Abstract

The utility model discloses a novel type automatic lock head for rolling gate, which is composed of a clamping board arranged on the bottom of rolling gate frame and a matched automatic lock latch, characterized in that the clamping block is constituted by a section of inclined plane, a section of horizontal plane and a section of vertical plane; the automatic lock latch is composed of a core box and a core arranged inside the cavity of the box, a connection head, a pull plate connecting the two, a rivet passing through a limit slot hole on the top of the core and being fixed between the upper and lower horizontal plates of the core box, a tension spring with one end fixed on the rivet, the other end fixed on the rivet inside the shell of the core tail. During usage, a lock latch rod of the rolling gate lock is inserted into the shell on the tail of the connecting head and fixed by a rivet, and the core box is fixed on the back wall of the rolling gate. And the open and close of the gate are realized through the coordination between the core and the clamping plate. The utility model has the advantages of simple structure, easy manufacture, and low cost. The safety property against theft is increased compared with original rolling gates. And the service life of the key is increased since the key is only used to open the gate and not to close the gate.

Description

The new type auto tapered end of rolling-gate

Technical field

The utility model relates to a kind of rolling-gate safety anti-theft lock.

Background technology

Existing rolling-gate, because the installation site is not just, or long-term use distortion, all can cause door lock not handy, the difficulty of particularly locking a door; And surpass large-scale rolling-gate more than 3.6 meters for width, since long to the arm of force of fulcrum, often need not require great effort and just the door pull-up can be existed serious potential safety hazard; And door lock also damages because of using very easily continually.

Summary of the invention

Goal of the invention of the present utility model is: the problems referred to above that exist at present rolling-gate, for the user provide a kind of simple in structure, make easy, with low cost, existing rolling gate door lock is improved, can improve greatly the new type auto tapered end of rolling-gate of existing rolling-gate safe antitheft performance effectively.

Goal of the invention of the present utility model realizes by implementing following technical proposals:

The new type auto tapered end of a kind of rolling-gate, form by clamp and suitable automatic locking tongue, it is characterized in that: the clamp that is installed in a pair of vertical doorframe of rolling-gate bottom, be a pair of have from top to bottom one section inclined-plane, again inwardly be converted into one section horizontal plane, be converted into one section perpendicular again, be convenient to the pulley of core print by self end and slide, again the special-shaped clamp that can be blocked by its horizontal plane section along its bevel phase; Suit is fixed on a pair of automatic locking tongue on the former rolling-gate Door-lock bolt, by core print, coupling head, one end is movable with the core print afterbody and connects, the other end is the movable arm-tie that connects with the coupling head head, they are contained in core print box in the cavity, pass the rivet that the spacing slotted eye of core print housing end face, two ends are separately fixed on the core print box upper and lower plates face, core print and core print box are joined together, and be contained in the core print housing, an end is fixed on this rivet, the other end is fixed on the core print housing afterbody inwall elongation spring forms.

Additional technical feature is:

1. the described core print that is contained in the core print box cavity is that an end is equipped with pulley, end face and is had spacing slotted eye, cross section is the housing of  shape.

2. the described coupling head that is contained in the core print box cavity is a cross section and the identical  shape of core print housing cross section housing.

3. a described end is movable with the core print afterbody and connects, the other end is the movable arm-tie that connects with the coupling head head, is that an end is sleeved on the interior rivet of core print afterbody housing, the other end is sleeved on the flat annular rigid slab on the rivet in the coupling head head shell.

4. be contained in the elongation spring in the core print housing, the one end be fixed on the core print box up and down on the rivet in two level board faces, the other end is fixed on the rivet in the core print afterbody housing.Advantage of the present utility model is: simple in structure, make easy, with low cost, can with the use that matches of various rolling-gates, improved existing rolling-gate safe antitheft performance greatly, and improved the application life of door lock key greatly.

The specific embodiment

The new type auto tapered end of a kind of rolling-gate is made up of clamp 2 and suitable automatic locking tongue; Clamp 2 is installed in the bottom of a pair of vertical doorframe 1 of rolling-gate, and it is a pair of one section inclined-plane to be arranged from top to bottom, inwardly be converted into one section horizontal plane again, is converted into the deformed steel flats of one section perpendicular again; The automatic locking tongue comprises: be contained in the metal core print 4 in metal core print box 5 cavitys, flat annular steel arm-tie 8, metal coupling head 9 primary clusterings such as grade; Core print 4 is that a cephalic par is equipped with pulley 3, end face and has spacing slotted eye 14, cross section is the metal shell of , at the housing afterbody rivet 15 is housed; Coupling head 9 is a cross section and the identical  shape of core print 4 cross sections metal shell, in this housing head rivet 10 is housed, and afterbody is equipped with rivet 12; Flat annular steel arm-tie 8, one ends are sleeved on the rivet 15 in the core print 4 afterbody housings, the other end is sleeved on the rivet 10 in coupling head 9 head shells; Core print box 5 is that a cross section is

The metal shell of shape; A rivet 6 is housed in core print 4 housings, these rivet 6 tops pass spacing slotted eye 14 on the core print end face, go up the top is separately fixed at the core print box about in the of 5 on two level board faces with going to the bottom, the spring 7 of an elongation also is housed in core print 4 housings, the one end is fixed on the rivet 6, the other end is fixed on the rivet 15, these assemblies are assembled in the core print box 5, have constituted the automatic locking tongue.

Dead bolt bar 13 covers the rolling-gate door lock during use inject in the housing of coupling head 9 afterbodys, and by rivet 12 two assemblies are joined together, core print box 5 are fixed on the rolling-gate back wall again; When opening the door, with the key operated rolling gate door lock of rolling-gate, the dead bolt bar 13 pulling coupling heads 9 of this lock, by arm-tie 8 pulling core prints 4, spring 7 is elongated, core print 4 is toward the 5 interior retractions of core print box, when termination pulley 3 moves horizontally distance when surpassing the horizontal plane of clamp 2, upwards spur rolling-gate, core print 4 just rises on the clamp inclined-plane, and door is promptly opened; Down pull gently when closing, core print pulley 3 moves down into the clamp position and will move down along the inclined-plane under the effect of rolling-gate own wt, when arriving the bottom, inclined-plane of clamp, core print can stretch out under spring 7 restoring force effects, and is stuck under the surface plate of clamp, and door is with regard on the automatic locking, do not need to use again key lock, because key only need not close the door with opening the door, so the number of times that weares and teares reduces half, application life big leap ahead.
