Abstract

The utility model discloses a force-bearing quick release lock which comprises a lock nail (1) and a lock seat (2), wherein a lock head (3) is connected at the end part of the lock nail (1), a bushing (4) and a spring (5) are arranged on a lock rod of the lock nail (1) in a penetrating way, a lock nail hole (6) is arranged on the lock seat (2), a lock head clamping groove (7) is formed at the bottom of the lock seat (2), and a rotating slope (8) is arranged at one side of the lock head clamping groove (7). In the force-bearing quick release lock, the lock head can be clamped in the lock head clamping groove to finish connection by extruding and rotating the tail part of the lock nail and can be drawn out by extruding and reversely rotating the lock nail during disassembly; the force-bearing quick release lock has the advantages of simple structure, rapidness in assembly and disassembly, convenience for connection and the like; and when the lock head is clamped in the lock head clamping groove, the spring is in an elastic deformation state, and the force-bearing quick release lock has self-locking function.

Description

A kind of load quick-release lock

Technical field

The utility model relates to a kind of machanical fastener, particularly a kind of load quick-release lock.

Background technique

Since mechanical industry is come out; Locking device (like bolt) has just produced; Locking device is with a long history, has become the indispensable component of mechanical industry, as being widely used invariably on the instruments such as railway, bridge, electric power, mine, aircraft, tank, automobile.Along with industrial expansion, also need locking device to have the function of fast lock, quick-release simultaneously at some special occasions; Existing fast lock bolt also emerges in an endless stream; But these fast lock devices always also keep this worm structure in using process; Just two or three screw threads are adopted in conversion, though improved the connection speed of locking device like this, it still is not very quick, convenient using.Simultaneously some occasion also deposit can't fixation fastener (like nut) problem, as just can't nut being placed on desired area in narrow space, the problems referred to above have restricted the using scope of locking device.

Summary of the invention

The purpose of the utility model is, provide a kind of simple in structure, loading and unloading are quick, easy to connect, the load quick-release lock of band self-locking, can overcome the deficiency of existing technology.

The technological scheme of the utility model: it comprises pinning and lock, is connected with tapered end in the pinning end, on the locking bar of pinning, is installed with lining and spring; On lock, offer locking nail hole, be provided with the tapered end draw-in groove, be provided with the turn slope in a side of tapered end draw-in groove in the bottom of lock.

The both sides of locking nail hole are provided with positioning hole on lock.

Be socketed with clamping sleeve on the lining.

Compare with existing technology, the utility model is through connecting tapered end, socket lining and spring on the locking bar of pinning in the pinning end; On lock, offer locking nail hole; In the bottom of lock the tapered end draw-in groove is set; Side at the tapered end draw-in groove is established the turn slope; With the locking nail hole contraposition of pinning and lock, extruding pinning afterbody and rotation just can be connected to tapered end to accomplish in the tapered end draw-in groove and connect like this, and extruding and counter-rotating pinning just can withdraw from pinning during dismounting; Have superiority such as simple in structure, that loading and unloading are quick, easy to connect; In the time of in tapered end is connected to the tapered end draw-in groove, spring is in elastic deformation, makes to have the utlity model has auto-lock function.Both sides at the locking nail hole of lock are provided with positioning hole, convenient like this lock predetermined fixed are connected; On lining, be socketed with clamping sleeve, the function class of clamping sleeve and pad seemingly but links together with lining, and just the similar operations such as pad, compression spring of setting level are exempted in installation and removal simultaneously; Therefore the utility model can be popularized and applied to various mechanical industries.

Embodiment

Embodiment: as shown in Figure 1; The locking device of the utility model is pinning 1 and lock 2; When making pinning 1, elder generation is spring of socket 5 and lining 4 on the locking bar of pinning 1, and an end of the spring 5 of socket withstands on the afterbody of pinning 1; The other end is connected in the lining 4, on lining 4, is socketed with a clamping sleeve 10 in addition for the lifting surface area that increases pinning and fixation simultaneously; Connect behind the above-mentioned parts and to offer a circular hole in the end of pinning 1; In circular hole, insert short pin and constitute tapered end 3; Spring 5, lining 4 and clamping sleeve 10 all are connected between the afterbody and tapered end 3 of pinning 1 like this, be connected in one, thus installation and removal simultaneously in use; Exempt the similar operations such as pad, compression spring of setting level.When making lock 2; On the base plate of lock 2, offer earlier a locking nail hole 6; The shape of locking nail hole 6 is similar with the shape at tapered end 3 positions, and the bottom figure of lock 2 is as shown in Figure 2, when the processing lock, also needs the tapered end draw-in groove 7 at clamping tapered end of the bottom of lock 2 processing 3 pins; Process the turn slope 8 of constant slope in tapered end draw-in groove 7 lower sides, simultaneously on lock 2, the both sides of locking nail hole 6 also are drilled with the convenient positioning hole 9 that connects lock 2.

In use, can in advance lock 2 be fixed to through positioning hole 9 and need the installation position, pinning 1 is passed needs fixture, and the afterbody of extruding pinning 1 also rotates to an angle, and tapered end 3 is connected in the tapered end draw-in groove 7 can accomplishes fast lock; Extruding tapered end 3 and counterrotating can be accomplished quick-release.

Claims

1. a load quick-release is locked, and it comprises pinning (1) and lock (2), it is characterized in that: be connected with tapered end (3) in pinning (1) end, on the locking bar of pinning (1), be installed with lining (4) and spring (5); On lock (2), offer locking nail hole (6), be provided with tapered end draw-in groove (7), be provided with turn slope (8) in a side of tapered end draw-in groove (7) in the bottom of lock (2).
