Description

The invention relates to belts for transport vehicles, more specifically to fast-acting m locks, to connect the system, the belt is molded with a part of the creile to the body.

The high-speed locks for safety belts of airborne vehicles, consisting of 13 two interlocking parts, one of which is uncovered with one of the parts installed in it, and an rom / bumper part; 1o connected to partus t) ansnor-1 means of mediating 1.

However, in the known locks, the practical activity of the kinetic body of the human body is abruptly slowing down the movement of the trans-organic agent.

The technical solution closest to the invention is a quick-release locking device for a safety belt of transport means containing two recessing parts, one of which is wound in the form of an axle hole with an axle hole, in which an interleaved brush attached to the opening hole and equipped with an axle hole is installed. inserted into the hole of the Cornus of the other part, in which the fully mounted and rotatable and immersed with the central part of the uriornaya verhosti Ko | mi, entering the ring pin of the shtyr, as well as with the bores covering the inner side of the side surface of the lock between the locks of the lock of the cylindrical locking element, bushing separator with an axial bore, longitudinal slots and holes for the axes Sooachsk and Nromezh toch about vhlku, coupled with the detail of inclining to the body 2.

The lock is known to be operated one-handedly, however, this requires nroiz1), two movements of opening: pull out ujTbipb for Hj) oyiii) iHy and simultaneously draw a kionku bol1) H1nm ovalts of the same hand.

The aim of the invention is to demonstrate the complexity of the castle’s deconstruction and the new conveniences of irnation.

This is achieved by those. that the blocking element is fastened at the outer end of the stem, the spring of which is installed with the possibility of holding and subsequently in the extended) 13 pin to the unor is naked, and the opening opening handle encloses the pin of the pin .5 and is disposed with the possibility of displacement along its axis and unilateral action on the inner end of the stem in his liking

A-A in FIG. one; in fig. 3 shows the lock in an intermediate position during the closing process; in fig. 4, however, in the closed state; in fig. 5 - lock at the beginning of the opening; in fig. 6 is a section BB in FIG. five.

The lock consists of two interlocking parts, one of which is made in the form of having 1 pin 2 with a ring with an annular groove 3 at the end inserted into the opening of the housing 4 of the other part.

B pin 2, along its axis, a hole is made, in which the stem 5 with the fixed on its outer end is blocked by an element 6 in the form of cylinders} 1 of the drill boss. The rod is made in stage, and on its shoulder there is a set-up washer 7 to serve, and an emphasis for a spring 8 supported by the other end on the sleeve 9 fixedly mounted in the pin. The inner end of the stem 5 with a gap passes through the bore of the sleeve and the hole of the cross member 10. With the end of the stem, the locking ring 11 is rigidly connected across the cross bar. The cross bar is installed in guides forming the walls of the longitudinal groove of the pin, and its ends are located in sections 13 connected between by itself, for example, rivet.mp, and the forming pin and eye handle of the drive for opening the lock. The handle covers the eyelet with a gap and is located with the possibility of movement along the axis of the pin and unilaterally acting on the inner end of the rod in the direction of its retraction inside the pin. The pin eye also covers the tape 14 passing through a slot in the handle body, forming a system of LECEMP security.

In the case 4 of the lock in the separator 15 pa axles x16 pawl 17 are mounted, they are equipped with a cylindrical part 18 pa the thrust surface of the case. The dogs are mounted on the axles with a gap that excludes the non-proliferation of efforts arising from opening the lock on the senator.

Dogs. Can be two n more. They have protrusions 19 which are included in the ring pin 3 pin, as well as protrusions 20 encompassing the locking element 6 when the lock state is locked. Installing the rod with a blocking element in the pin hole with a radial clearance, as well as the presence of a gap between the pin and the housing hole, ensure self-alignment of all worn parts and even distribution of the load on the dogs n on their projections 19, which perceive tensile forces acting on the system security.

The lock body 4 is connected to the body part 21 via an intermediate sleeve 22. Outside, a rubber or plastic cover 23 is put on the carnus.

The eyebolt pin can be made as a composite or single piece. In the latter case, after the hole has been machined, this is ensured by the displaced initial position of the lug 24 of the eyelet, the latter being removed in the stamp until its center coincides with the pin axis.

When locking the lock, while holding its hand connected to the lu mock system, by the case of the lock, insert the lock into the hole of the case. The insertion of the pin is facilitated by the entrance conic chamfer of the housing bore and the copy shape of the surface tangent to the rounded

edge of the locking element and the pin end. When inserting a pin is a blocking element, then the end of the pin is separated from the lips of 19 dogs 17, turning them so that the projections slide along the outer surface of the pin.

The blocking element, resting the rounded end part on the tips of the protrusions of the 20 dogs, stops. With further advancement of the pin, the blocking element and the stem are retracted inside the pin, while the spring 8 is compressed, and the locking ring 11 is withdrawn from the upper surface of the cross member 10 until the protrusions of the dog 19 approach the edge of the ring groove of the pin. In the closure hopper (see Fig. 3), when the protruding dvpzhenpp P1tyr continues, the protrusions of 19 dogs, tend to turn away under the action of their protrusions 20, unclipping the forces from the spindle of the chain locking element, enter the annular groove of the pin, and the locking element the protrusions 20 (see Fig. 4), enters between them, blocking the pawl from turning.

To unlock the lock, it is necessary to hold the handle body, and in its direction from the lock body, in this case, the handle body (see Fig. 5) moves along the axis of the crossbar, carried away by crossbars with njTOKOM and compressing the spring. The locking element releases the protrusions of the 20 dogs, which, having been pushed under the action of the protruding 19 radial forces that protrude as a result of engagement with the annular groove of the extracted pin, release the latter.

The advantages offered by my quick-release lock are simplicity of design and reliability in operation, which is eliminated by uniform loading of dogs.
