Abstract

The utility model relates to a cylinder, in particular a cylinder for a U-shaped lock. The cylinder comprise a lock body and a lock ring. The lock ring consists of a plurality of locking pins that are symmetrically retained in different directions, has a compact structure, resists the impact of external force in different directions, increases the anti-destruction ability and improves the theft-proof performance.

Description

A kind of tapered end

The utility model relates to a kind of tapered end, particularly the tapered end of " U " shape lock.

The transmission mechanism and the stop structure of existing tapered end mainly contain two kinds, and a kind of be axial moving device, and after mostly being key and opening the locking password, lock core or lock pin can move axially (key roof pressure) and insert lock ring groove pinning lock ring under the alignment pin guiding;

Another kind of key is opened locking password rear lock core under key drives, and can rotate in order to change brake mechanism, stirs the commentaries on classics lock lock ring can be pulled out, and lock is opened, and can press lock ring when locking, and changes lock and resets in the torsion spring effect, snaps in the lock ring groove.The tapered end of present U-shaped lock, although simple in structure, the stop position is out of shape under external force collision easily, makes tapered end malfunctioning.

The purpose of this utility model is to provide a kind of external force resistance impact strong for overcoming above-mentioned the deficiencies in the prior art, the tapered end that theftproof performance is good.

For achieving the above object, the utility model has adopted following scheme: tapered end comprises lock body, lock ring, lock body end axial direction is embedded with rotating shifting part and lock core and lock ring seat, the lock ring head is inserted into the lock ring seat and pins lock ring by stop mechanism when locking, shifting part and lock core interlock, it is characterized in that: be provided with the lock ring groove before and after on the same cross section of lock ring head symmetrically, lock ring seat wall correspondence position is provided with lockpin hole, be provided with telescopic lock pin in the lockpin hole, lock pin length is greater than lock ring seat wall thickness, shifting part is made of two disks that are parallel to each other and link, the lock ring seat is located between two disks movingly, lock ring seat axis and shifting part axis normal, the position corresponding to lock pin sliding trace in the above when shifting part rotates is provided with surface groove.

Adopted the tapered end of said structure, lock ring is blocked symmetrically from different directions by a plurality of lock pins, and structure is also very compact, therefore can resist the external force collision of different directions, has strengthened survivability, has improved theftproof.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment simultaneously.

Accompanying drawing 1 is embodiment (blocking) structural representation;

Accompanying drawing 2 is embodiment (unlocking condition) structural representation;

Accompanying drawing 3 is local enlarged diagram.

As shown in Figure 1, the tapered end of present embodiment comprises lock body 16 and lock ring 1, lock ring 1 head is provided with the lock ring groove 2 of the annular groove formation of cross section semicircular in shape, lock body 16 ends are axially arranged with tapered end chamber 17, drum shape tapered end shell 18 is located at wherein, shifting part 6 is made of two disks that are parallel to each other and have part edge to be linked together, lock ring seat 3 is located between two disks movingly, lock ring seat 3 axis and shifting part 6 axis normal, when rotating, shifting part 6 is provided with different and surface groove 7 that constitute by the arc groove that the inclined-plane is connected by two sections degree of depth corresponding to the position of lock pin 4 sliding trace in the above, lock ring seat 3 walls are arranged with two lockpin holes 5 corresponding to the position of lock ring groove 2, be provided with steel ball in the lockpin hole 5 movingly and constitute lock pin 4, be provided with spring housing 10 in the lock ring seat 3 movingly, spring housing 10 is provided with the inside spring storage chamber 8 of opening, in establish ejector spring 9, the inboard disc center of shifting part 6 is provided with centre bore and alignment pin 19 movingly and place on the tapered end shell 18, alignment pin 19 between inboard disc and the locker shell 18 is provided with torsion spring 21, the outboard disc of shifting part 6 even constitutes linkage structure with the lock core 11 fixing connection that are set in movingly in the tapered end shell 18, be provided with lateral pin 12 in the lockhole 15 on the lock core 11, lateral pin 12 is provided with lockhole cap 13 and port lid torsion spring 14, and is fixing by baffle ring 20 between tapered end shell 18 and the lock body 16.

During use, rotational lock core 11 after key 22 is opened the locking password, drive shifting part 6 rotates to an angle and makes one section darker aligning lock pin 4 position of the degree of depth in the surface groove 7, outside under the ejector spring active force of lock ring 1 this moment in spring housing 10, lock pin 4 is reduced in the surface groove 7 in the effect lower part of this power, and lock ring 1 is opened; Lock ring 1 head is inserted in the lock ring seat 3 spring housing 10 is depressed when locking, and shifting part 6 rotates under the effect of torsion spring 21, by surface groove 7 lock pin 4 is ejected to be stuck in and pins lock ring 1 in the lock ring groove 2.
