Abstract

The utility model relates to a U -type lock head, including the hasp, the tapered end body and shell, be equipped with the lock core in the tapered end body, the slide bar, it sets up the hasp jack to correspond on the tapered end body and the shell, the upper end eccentric settings shifting block of lock core, the shifting block drives the slide bar seesaw of both sides, the recess is seted up to the equal axial in both ends at the tapered end body, the recess intersects vertically with the hasp jack, slide in the recess and set up the latch hook knot, one end and slide bar that the latch hook was detained meet, the other end forms the locking cooperation with the hasp tip that inserts the hasp jack, the constant head tank is seted up to tapered end body surface face in lock core both sides, the stable piece of guide way is taken to the scarf joint in the constant head tank, the slide bar inserts in the guide way. The utility model overcomes the structure that ordinary U -type lock head locking means exists among the prior art is simple and crude, and the reliability is low, the poor defect of theftproof performance, through above -mentioned detailed design, has effectively improved the reliability of U type lock locking, has simple structure compactness, convenient assembling, good reliability, the effectual advantage of theftproof.

Description

A kind of U-shape lock tapered end

Technical field

This utility model is related to a kind of U-shape lock tapered end.

Background technology

Existing U-shape lock lock locking device, all includes tapered end and is assemblied in locking plate in tapered end, lock core, tapered end It is additionally provided with lock latch jack in body, lock core drives locking plate forward or reverse, so that the groove that locking plate is latched with U-shape lock is engaged or separate, Thus reaching locking, the purpose unlocked.This U-shape lock lock locking device, its assembling structure is simple and crude, and reliability is low, anti-theft Can be poor, it has been almost into the ornaments in bicycle.Therefore do not adapt on the theftproof performance to lock that consumer increasingly increases Requirement.

Content of the invention

In order to overcome the structure that in prior art, common u-shaped lock locking mechanism exists simple and crude, reliability is low, anti-theft Can difference problem, this utility model provides a kind of U-shape lock tapered end, the structure of this U-shape lock tapered end is simple, easy to assembly, sealed can Lean on, theftproof performance strong.

This utility model solves its technical problem and be employed technical scheme comprise that：Including lock bolt, tapered end and shell, tapered end It is equipped with lock core, slide bar in body, tapered end and shell be correspondingly arranged lock latch jack, the upper end eccentric setting shifting block of lock core, Shifting block drives the slide bar of both sides to move forward and backward, and all axially opens up groove at the two ends of tapered end, groove phase vertical with lock latch jack Hand over, slide in groove setting latch hook button, one end of latch hook button is connected with slide bar, the latch end of the other end and insertion lock latch jack Form lock fit.

Open up locating slot on the tapered end surface of lock core both sides, in locating slot, rabbet the stable block with gathering sill, slide bar is inserted Enter in gathering sill.

The axial cross section that groove and latch hook are buckled on tapered end is " Qian " shape, and tapered end has the extension of radial direction in a groove Be formed as limiting section, latch hook button and limiting section form spacing cooperation.

The extension that tapered end has radial direction above the groove of limiting section side is formed as strengthening cover plate, and lock latch jack passes through Strengthen cover plate.

In tapered end, the side of latch hook button has radial protrusion and is formed as contiguous block, the company that contiguous block is opened up with slide bar end Connect hole to plug.

This utility model, by above-mentioned specific design, effectively increases the reliability of U-shape lock locking, has structure simply tight Gather, easy to assembly, highly reliable, good anti-theft effect advantage, be suitable for all kinds of U-shape locks have in popularization and application.

Brief description

Below in conjunction with drawings and Examples, detailed content of the present utility model is described.

Fig. 1 is decomposition texture schematic diagram of the present utility model.

Fig. 2 is this utility model assembling structure schematic diagram in the locked state.

Fig. 3 is this utility model assembling structure schematic diagram in the on state.

Specific embodiment

As illustrated, this utility model includes lock bolt 1, tapered end 2 and shell 3, in tapered end 2, it is equipped with lock core 4, slide bar 5, tapered end 2 and shell 3 are correspondingly arranged lock latch jack 6, the upper end eccentric setting shifting block 7 of lock core 4, shifting block 7 drives both sides Slide bar 5 move forward and backward, all axially open up groove 8 at the two ends of tapered end 2, groove 8 is intersected vertically with lock latch jack 6, groove 8 The middle setting latch hook button 9 that slides, one end of latch hook button 9 is connected with slide bar 5, the lock bolt 1 end shape of the other end and insertion lock latch jack 6 Become lock fit.Open up locating slot 10 on tapered end 2 surface of lock core 4 both sides, in locating slot 10, interlocking is steady with gathering sill 11 Determine block 12, in slide bar 5 insertion gathering sill 11, stablize gathering sill 11 and the cooperation of slide bar 5 on block 12 and can strengthen slide bar 5 translation Stability has guide effect concurrently.Groove 8 and latch hook button 9 axial cross section on tapered end 2 is " Qian " shape, and tapered end 2 is in groove 8 In there is the extension of radial direction be formed as limiting section 16, latch hook button 9 and limiting section 16 form spacing cooperation.Tapered end 2 is in limiting section The extension that the top of 16 side grooves 8 has radial direction is formed as strengthening cover plate 13, and lock latch jack 6 passes through strengthens cover plate 13.Tapered end In body 2, the side of latch hook button 9 has radial protrusion and is formed as contiguous block 14, the connecting hole that contiguous block 14 is opened up with slide bar 5 end 15 plug.During unlatching, rotate lock core 4, the shifting block 7 of eccentric setting also rotates simultaneously, band moving slide-bar 5 and latch hook button 9 make straight line Motion, is made latch hook button 9 be separated with the lock slots 17 on lock bolt 1, extracts lock bolt 1 and unlock；During locking, on tapered end 2 and shell 2 Insert lock bolt 1 in the lock latch jack 6 being correspondingly arranged and opposite direction rotates lock core 4 and puts in place, shifting block 7 drives lock strap moving slide-bar 5 and lock Reverse linear motion made by fastener 9, and latch hook button 9 is fastened with the lock slots 17 on lock bolt 1, and lock bolt 1 is locked.Above-described enforcement Example is only that the preferred implementation to a kind of this utility model U-shape lock tapered end is described, the not design to utility model It is defined with scope, on the premise of without departing from this utility model scheme, those skilled in the art are to skill of the present utility model Various external form modifications and improvement that art scheme is made, all should fall into a kind of protection domain of this utility model U-shape lock tapered end.
