Abstract

A high-strength hydraulic-shearing-resistant motorcycle lock consists of a lock bow and a bolt, wherein an idle lock cylinder and a lock body are assembled to form a sealed U-shaped lock; a C end of the lock bow is connected with a C' end of the lock body by taking a Phi 6mm cylindrical pin as a rotating shaft; a D end of the lock bow is connected with the bolt in a D' end of the lock body; and an oblate hole in the center of the bolt is connected with a rotating shaft of the idle lock cylinder. When inserted into the idle lock cylinder hole but not in place, a key is idle while being rotated and the bolt can not rotate; and when inserted in place, the key is rotated clockwise to unlock and rotated counterclockwise to lock.

Description

The anti-hydraulic shear lock for motorcycle of high strength
Technical field
The utility model relates to the lock that a kind of lock especially includes the portable hydraulic shear ability of opposing; Be applicable to motorcycle (containing Harly Scooter), electric motor car, bicycle, warehouse gate, push-and-pull iron canopy door etc.
Background technology
At present, the structure of known anti-hydraulic shear lock for motorcycle is comprised of lock bow, lock tongue, lock core and lock body.
One, anti-hydraulic shear is strong not.The diameter of lock bow is less than Φ 25mm, and sectional area is less than 5cm 2, hardness is not resisted portable largest domestic specification hydraulic shear and can be cut diameter of phi 25mm steel part less than the HRC50 degree.
Two, anti-technical unlocking poor performance.Lock core uses conventional lock cylinders, can open with master key, brill, prizes and does not also prevent, causes that vehicle is stolen often a generation.
Summary of the invention
The purpose of this utility model is inadequate for the ability that overcomes the anti-hydraulic shear of used anti-hydraulic shear lock for motorcycle for anti-technical unlocking poor performance.Provide a kind of lockset that the lockset of the portable hydraulic shear ability of opposing is arranged.Fig. 1.
The technical scheme that the utility model technical solution problem adopts is: the anti-hydraulic shear lock for motorcycle of high strength of the present utility model, and by lock bow (Fig. 2.), lock tongue and idle-run lock pin (Fig. 3.Fig. 4.), lock body (Fig. 5) is assembled into one, it is characterized in that: lock bow C end is that turning cylinder is connected with lock body C ' end by the straight pin of Φ 6mm, the interior lock tongue idle-run lock pin of lock bow D end and lock body D ' end contains and connects, the lock tongue center has flat round hole to be connected on the turning cylinder of idle-run lock pin, pegging graft when key has put in place into lockhole, clockwise rotates 90 ° and namely unblanks: namely shut counterclockwise.Fig. 4.
Described lock bow is superior alloy steel 40Cr, diameter of phi 30mm, sectional area 7cm 2, through the extraordinary nitrogen treatment of heat treatment, hardness is more than the HRC60 degree.Fig. 2.
The anti-liquid of described high strength is cut lock for motorcycle, and lock tongue and idle-run lock pin turning cylinder are contained in one., when key insertion idle-run lock pin hole, not putting in place, screw key is idle running: put in place, screw key drives the lock tongue rotation.Fig. 3.Fig. 4.
The anti-liquid of described high strength is cut lock for motorcycle, and lock body is selected No. 40 steel of high-quality, diameter of phi 38mm seamless steel pipe, through modifier treatment hardness at HB200.Fig. 5.
This lockset can not only be prevented technical unlocking, anti-drilling, pick-proof, anti-hammering, has more the function of the anti-hydraulic shear of enough high strength.
Description of drawings
Fig. 1 is that the anti-liquid of high strength of the present utility model is cut the lock for motorcycle structural representation.
Fig. 2 is the lock bow structure schematic diagram of the utility model Fig. 1.
Fig. 3 is that the utility model lock tongue connects schematic diagram with lock core.
Fig. 4 is that the utility model key is in position, pass schematic diagram.
Fig. 5 is the utility model lock body schematic diagram.
The specific embodiment
As shown in Fig. 1-5
The utility model has lock bow, lock tongue, idle-run lock pin, lock body to be assembled into one.Lock bow C end is that turning cylinder is connected with lock body C ' end by Φ 6mm straight pin, the interior lock tongue of lock bow D end and lock body D ' end is connected, and lock tongue center flat round hole is connected on the turning cylinder of idle-run lock pin, when original key insertion lockhole has put in place, clockwise rotate 90 degree, i.e. expenses; Namely shut counterclockwise.
Described lock bow (Fig. 2), the overstriking Hardening improves anti-hydraulic shear intensity.Lock bow adopts high duty alloy steel 40Cr, and diameter of phi 30mm is through the extraordinary nitrogenize of heat treatment, hardness HRC60.
Described idle-run lock pin, anti-technical unlocking is processed into round homalocephalus on turning cylinder, the circle homalocephalus is installed lock tongue (Fig. 3), plugging Φ 0.9mm cottor pin is connected, when lock core rotated, lock tongue is and then rotation also, and limit turn 90 degrees, when key inserts the idle running lockhole, do not put in place, screw key is idle running; Put in place, screw key, lock core shaft drives the lock tongue rotation, switch from.Namely work as dextrorotation and turn 90 degrees, lock could be opened, and is rotated counterclockwise 90 degree, namely shuts; If meet the key that is not the first wife, even be inserted into the position, also can rotate key, but just idle running, lock tongue does not rotate, and lock does not leave.Fig. 3 is that lock tongue connects figure with lock core; Fig. 4 is that key is in the position, pass, and described idle-run lock pin has anti-drilling and tamper-resistant function, meets drilling tool and bores lock core, and idle-run lock pin is followed the drill bit synchronous rotary, can not produce the cutting phenomenon.
Lock body is selected the high-quality steel No. 40, external diameter Φ 38mm seamless steel pipe, through modifier treatment greater than the HB200 degree.Can prevent hammering.Fig. 5.
