Abstract

The utility model relates to a lock of U-shaped tapered end, comprising a lock head body, a lock plate which is arranged in the lock head body and a lock core. The lock head body is in a transverse direction provided with a slide groove which crosses the jack of a lock bolt in a vertical way. The lock plate is assembled movably in the slide groove. A column pin is fixedly connected to the side wall of the lock plate. One end of a reset spring below the lock plate butts at the lock head body. The other end of the reset spring presses against the column pin. The upper end of the lock core is provided with a linkage pole block. The pole block is matched with the lock plate at the two sides. The utility model overcomes the defect that a common lock of U-shaped tapered end in prior art has simple structure, low reliability and poor performance of antitheft. Through the detailed design, the utility model has the advantages of simple and compact assembly structure, convenient operation, strong reliability and good antitheft effect.

Description

U-shape lock tapered end lock uint

Affiliated technical field

The utility model relates to a kind of U-shape lock tapered end lock uint.

Background technology

Existing U-shape lock tapered end lock uint, all comprise tapered end and be assemblied in locking plate, lock core in the tapered end that also be provided with lock latch jack in the tapered end, lock core drives the locking plate forward or reverse, the groove that locking plate and U-shape lock are latched engages or separates, thus the purpose that reaches locking, unblanks.This U-shape lock tapered end lock uint, its assembly structure is simple and crude, and reliability is low, theftproof performance is poor, almost has been into the ornaments in the bicycle.Therefore can not adapt to that the customer increases day by day to the requirement on the theftproof performance of lock.

Summary of the invention

Simple and crude in order to overcome the structure that common U-shape lock tapered end lock uint exists in the prior art, reliability is low, the problem of theftproof performance difference, the utility model provides a kind of U-shape lock tapered end lock uint, this U-shape lock tapered end lock uint simple in structure, easy to assembly, reliability is high, theftproof performance is strong.

The technical scheme that its technical problem that solves the utility model adopts is: comprise tapered end and be assemblied in locking plate, lock core in the tapered end, the chute that horizontally set and lock latch jack intersect vertically in tapered end, movable assembling locking plate in the chute, affixed pin on the sidewall of locking plate, one end of locking plate below back-moving spring props up tapered end, the other end is pressed against on the pin, and the upper end of lock core is provided with the shifting block of interlock, and shifting block matches with the locking plate of both sides.

The utility model is by above-mentioned specific design, has that assembly structure is simple compact, easy to operate, an advantage of good reliability, good anti-theft effect, is adapted at applying in all kinds of U-shape lock tools.

Description of drawings

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

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A sectional view.

As shown in the figure, the utility model comprises tapered end 1 and is assemblied in locking plate 2, lock core 3 in the tapered end 1, tapered end 1 is by aluminium cast global formation, the chute 5 that horizontally set and lock latch jack 4 intersect vertically in tapered end 1, movable assembling locking plate 2 in the chute 5, affixed pin 6 on the sidewall of locking plate 2, one end of locking plate 2 below back-moving springs 7 props up tapered end 1, the other end is pressed against on the pin 6, and the upper end of lock core 3 is provided with the shifting block 9 of interlock, and shifting block 9 matches with the locking plate 2 of both sides.During rotational lock core 3, shifting block 9 also rotates simultaneously under user mode, and back-moving spring 7 discharges also and drives locking plates 2 along chute 5 moving linearlies by pin 6, and the end of locking plate 2 and U-shape lock door bolt 8 are separated, and U-shape lock is fastened 8 with a bolt or latch and extracted and unblank; Insert U-shape lock door bolt 8 and counter-rotation lock core 3 to 90 degree location during locking, shifting block 9 promotes locking plate 2 along chute 5 moving linearlies, compression reseting spring 7, locking plate 2 lockings.

Claims

1, a kind of U-shape lock tapered end lock uint, comprise tapered end and be assemblied in locking plate, lock core in the tapered end, the chute that horizontally set and lock latch jack intersect vertically in tapered end, movable assembling locking plate in the chute, it is characterized in that affixed pin (6) on the sidewall of locking plate (2), an end of locking plate (2) below back-moving spring (7) props up tapered end (1), and the other end is pressed against on the pin (6), the upper end of lock core (3) is provided with the shifting block (9) of interlock, and shifting block (9) matches with the locking plate (2) of both sides.
