Description

A kind of novel anti-lock of cutting

Technical field

The utility model relates to a kind of lockset, and particularly a kind of preventing cut the novel anti-lock of cutting of implementing theft by hydraulic pressure.

Background technology

Electric bicycle, battery-operated motor cycle and motorcycle (hereinafter being referred to as motorcycle for sake of convenience) are the important tool that people go on a journey, but the stolen incident of motorcycle happens occasionally, have plenty of the car owner and control oneself and motorcycle is not locked, have plenty of the burglar and steal by the mode of destroying theftproof lock.On August 14th, 2002, the Chinese patent CN2505564Y of bulletin disclosed a kind of portable security alarm lock, it comprises a U type bar and is located at U type masthead portion and the end connecting rod hinged with it, by the lock body releasable connection, and be positioned at lock body (lock core) outside and be provided with sheath and prevent that it from being opened or prying open by the lawless person between described U type bar one end and the connecting rod free end.The theftproof lock of this U type bar structure is most popular a kind of theftproof lock on the present motorcycle, find in the use, increasing thief is cut by hydraulic pressure and is stolen, because U type bar is easy to be cut off, therefore uses the theftproof lock offender of this kind structure still to have an opportunity to take advantage of.

The utility model content

The purpose of this utility model provides a kind of good novel anti-lock of cutting of performance of cutting simple in structure, anti-.

The technical scheme that the utility model adopted is such: a kind of novel anti-lock of cutting, comprise left arc watt, right arc watt, bearing pin, tapered end and lock core, described bearing pin is heavy be located at an axial side of right arc watt and to the right arc watt opposite side extend, described left arc watt is watt hinged by this bearing pin and right arc, the position of the corresponding bearing pin of right arc watt opposite side is provided with the countersunk head plug, and this countersunk head plug is connected with the bearing pin interference fit, tapered end is located on the left arc watt, lock core is removable to be located on the tapered end, the position of right arc watt last corresponding lock core is provided with fixing hole, nationality is entered and is withdrawed from relative positioning and the release that this fixing hole is realized left arc watt and right arc watt by lock core, the axial length of left side arc watt and right arc watt is between 25～55mm, and left arc watt or right arc watt tool are to radially or axial projection portion.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by two semicircle tile structures, suitable equally for this lockset of wheel hub that does not have perforate, by two semicircle tile and tires are set, gap between the wheel hub, the cutting edge that makes hydraulic pressure cut can not enter between wheel hub and the arc watt, simultaneously the axial length of left arc watt and right arc watt is arranged to surpass the opening of hydraulic pressure shearing blade, can't realize cutting off operation, and bearing pin adopts the countersunk head setting, finish once assembling two arc tiles are separated again, whole anti-to cut lock construction simple, and the anti-performance of cutting is good.

The specific embodiment

With reference to figure 1 and Fig. 2, embodiment discloses a kind of novel anti-lock of cutting, comprise left arc watt 1, right arc watts 2, bearing pin 3, tapered end 4 and lock core 5, described bearing pin 3 has the relatively large cap portion of diameter, described right arc watts 2 is provided with axis hole 21, bearing pin 3 by axis hole 21 heavy be located at an axial side of right arc watts 2 and to the right arc watt 2 opposite sides extend, the position of the corresponding bearing pin 3 of right arc watt 2 opposite sides is provided with countersunk head plug 31, one end interference fit of one end of described countersunk head plug 31 and bearing pin 3 is provided with, described left arc watt 1 one ends watt can rotate with respect to bearing pin 3 by hinged two arcs that are arranged so that of this bearing pin 3 and right arc watts 2, tapered end 4 is located on the left arc watt 1, lock core 5 movably is located on the tapered end 4, the position of corresponding lock core 5 is provided with fixing hole on the right arc watts 2, nationality enters and withdraws from relative positioning and the release that this fixing hole is realized left arc watt 1 and right arc watts 2 by lock core 5, the axial length of left side arc watt 1 and right arc watts 2 is 35mm, and right arc watt 2 tools are to lug boss 22 radially.Described lug boss 22 is used to prevent to cut lock around wheel, and it also can be an axial projection portion, and the free end of the free end of left arc watt 1 and right arc watts 2 can be that what to separate also can be contacted.Described tapered end and on lock core can be located on the right arc watt, corresponding left arc watt is provided with the fixing hole that lock core is entered and withdraw from, near the arc of this fixed hole position bearing pin watt inboard.

Design philosophy of the present utility model is watt to embrace wheel by two arcs that are hinged, by being set, two arcs watt prevent that under the locking states and the gap of tire inboard cutting edge that hydraulic pressure is cut from entering between arc watt and the tire, simultaneously the axial length of arc watt is arranged to surpass the maximum subtended angle of cutting edge that common hydraulic pressure is cut, and makes it finish shearing work along the axial direction of arc watt.

Claims (1)
