Abstract
A kind of pulley of switchgear assembly cabinet door disclosed by the invention corrects structure, including cabinet door and doorframe tank bracket, further includes: is fixed on the positioning buckle of doorframe tank bracket appropriate location, the upper end for positioning buckle curves inwardly and downwardly；One is fixed on the pulley bracket fixation member on cabinet door inner surface；One end and the hinged pulley bracket moving component in pulley bracket fixation member upper end；The pulley being mounted on the other end of pulley bracket moving component；One end is connect with pulley bracket fixation member, the spring that the other end is connect with pulley bracket moving component.The degree of protection that should reach the purpose of the invention is to meet voltage switchgear, and effectively prevent cabinet door due to gravity, the phenomenon that laterally having a down dip close to door lock vertical, prevent hinge long-time stress from deforming.Effective to improve switchgear in the handling process, due to the unlocked jail of cabinet door key lock careless omission, cabinet door is possible to the case where arbitrarily opening, injure personnel.But also whole group switchgear assembly cabinet appearance more neat appearance.
Description
Technical field
The present invention relates to switchgear assembly technical field, in particular to the pulley of a kind of switchgear assembly cabinet door is corrected
Structure.
Background technique
The fixation of voltage switchgear cabinet door, generally using door lock, fixed pulley, L-type bending sheet metal, to be oriented to and support
Close cabinet door.Since the gravity and hinge position of cabinet door have deviation slightly, pulley and L-type bending gold are fixed when the door is closed
Belong to piece not can cooperate well with support frame, adds trouble for operator, influences the appearance technique of whole group switchgear.So
Needing one kind not only can be reduced the workload of operator, but also degree of protection and appearance work that whole group switchgear can be made to reach requirement
The method of skill beauty solves the problems, such as.
Summary of the invention
Technical problem to be solved by the present invention lies in for above-mentioned technical problem present in existing complete switch cabinet door
And provide a kind of pulley correction structure of switchgear assembly cabinet door.It can easily close cabinet door, and can position cabinet door,
Mitigate downward power.For basic principle of the invention by pulley come the movement of leading block bracket, pulley bracket is fixed on cabinet door
On, pulley bracket extension spring makes bracket under tension, and when pulley clasps positioning buckle, elastic deformation, spring occur for spring
It is exactly the pulling force to cabinet door, the direction of this pulling force is obliquely upward to pulley bracket pulling force.According to force resolution, cabinet door is received
The pulling force and upward support force closed.
The technical problems to be solved by the invention can be achieved through the following technical solutions:
A kind of pulley correction structure of switchgear assembly cabinet door, including cabinet door and doorframe tank bracket, further includes:
It is fixed on the positioning buckle of doorframe tank bracket appropriate location, the upper end of the positioning buckle is inwardly and downwardly curved
It is bent；
One is fixed on the pulley bracket fixation member on cabinet door inner surface；
One end and the hinged pulley bracket moving component in pulley bracket fixation member upper end；
The pulley being mounted on the other end of the pulley bracket moving component；
One end is connect with the pulley bracket fixation member, the bullet that the other end is connect with the pulley bracket moving component
Spring.
In a preferred embodiment of the invention, the pulley is fixed on the pulley bracket by pulley bracket and moves
On the other end of component, the pulley bracket is vertical with the pulley bracket moving component to be connect.
The degree of protection that should reach the purpose of the invention is to meet voltage switchgear, and effectively prevent cabinet door due to
The phenomenon that gravity laterally has a down dip vertical close to door lock, prevents hinge long-time stress from deforming.The effective switchgear that improves is being removed
During fortune, due to the unlocked jail of cabinet door key lock careless omission, cabinet door is possible to the case where arbitrarily opening, injure personnel.But also whole
The complete switchgear cabinet appearance of group more neat appearance.
The pulley of switchgear assembly cabinet door according to the present invention corrects structure, carries pulley by design pulley, support
Movable support, spring and positioning buckle, allow the significantly more efficient correction of pulley to position cabinet door, and improve cabinet door due to by gravity to
Have a down dip vertical situation.
The present invention makes with lower-cost material, optimizes the scheme of switchgear assembly cabinet door, improves product
Quality, reduce the workload of operator.
Detailed description of the invention
Assembly between pulley Fig. 1 of the invention, pulley bracket fixation member, pulley bracket moving component and spring is shown
It is intended to.
The original state and stress diagram of the pulley correction structure of Fig. 2 switchgear assembly cabinet door of the present invention.
The spring elongation position of the pulley correction structure of Fig. 3 switchgear assembly cabinet door of the present invention and stress diagram.
The cabinet door closed position of the pulley correction structure of Fig. 4 switchgear assembly cabinet door of the present invention and the decomposition of cabinet door stress are shown
It is intended to.
Specific embodiment
Present pre-ferred embodiments are provided with reference to the accompanying drawing, to illustrate technical solution of the present invention:
Referring to Fig. 1 to Fig. 4, a kind of pulley of switchgear assembly cabinet door of the present invention corrects structure, including pulley bracket is consolidated
Determine component 7, pulley bracket moving component 6, pulley bracket 2, pulley 3, positioning buckle 4, spring 5.
Pulley bracket fixation member 7 is fixedly welded in cabinet door 1, and the upper end of pulley bracket fixation member 7 passes through active pin 8
Hinged with one end of pulley bracket moving component 6, pulley bracket 2 is fixedly welded on the other end of pulley bracket moving component 6,
Pulley bracket 2 is mutually perpendicular to pulley bracket moving component 6.Pulley 3 is mounted on pulley bracket 2.5 one end of spring and pulley branch
Frame fixation member 7 connects, and the other end is connect with pulley bracket moving component 6.In the initial state, spring 5 consolidates pulley bracket
Determine component 7 and the support of pulley bracket moving component 6 shape in obtuse angle.
Positioning buckle 4 is installed on the doorframe tank bracket 9a of switchgear, and the upper end of positioning buckle 4 curves inwardly and downwardly.
When cabinet door 1 is under manpower drive, pulley 3 and positioning buckle 4 are moved to when contacting, since pulley 3 is in pulley branch
The oblique upper of frame fixation member 7, the resultant direction that pulley 3 is subject to are the oblique upper of pulley bracket moving component 6, therefore pulley 3
When moving upwards on positioning buckle 4, meeting extension spring 5 is moved upwards.Pulley bracket moving component 6 and pulley bracket 2
Vertical design is the scope of activities for increasing pulley 3 and entering positioning buckle 4.
When pulley 3 moves upward to positioning 4 top of buckle on positioning buckle 4, by the pulling force of spring 5, cross
The perpendicular joints of positioning 4 top of buckle, pulley bracket moving component 6 and pulley bracket 2 are under inertia force effect, along positioning
The inclined-plane of buckle 4 moves down, due to spring 5 deformation power and block positioning buckle 4.The resultant force being subject to obliquely, divides power
Solution is upward power and the power into cabinet.
Entire implementation process embodies, and pulley 3 on positioning buckle 4 when moving, due to external force, so that spring 5 produces
Raw pulling force blocks positioning buckle 4 by deformation.It solves since the gravity and hinge position of cabinet door have deviation slightly, and makes
The phenomenon that deforming at hinge long-time stress.And cabinet door is improved due to vertical situation downwardly gravitating of inclining.It ensure that out
The degree of protection for closing cabinet, so that whole group switchgear appearance technique is beautiful and tidy.
