Abstract
The utility model relates to an anti-disassembling device for the screw bolt of a bicycle lock. The original lock head block is divided into two parts of a lock head seat and a lock head rotary disk. One center hole and a plurality of dormant screw bolt holes are arranged on the lock head seat. One thread center hole and one through hole for passing a steel rod are arranged on the lock head rotary disk. The lock head seat, the lock head rotary disk, and the steel rod are connected together by a screw small shaft with a step. The through hole on the lock head rotary disk, and the through hole is convenient for a screw bolt to pass through the dormant screw bolt holes to be connected with an attached block. The inner side of a lock core block disk is provided with two dormant screw holes. When the steel rod is locked, the screw holes are just blocked by a rod body. When a vehicle lock is opened, the anti-disassembling device for the screw bolt of a bicycle lock can install and disassemble the screw bolt. When the vehicle lock is locked, the screw bolt can be hidden by the anti-disassembling device for the screw bolt of a bicycle lock.
Description
The utility model relates to combined type lock bolt and prevents the device dismantled
Combined type anti-theft bicycle lock (patent No. 91214445.9) is to be connected with attached respectively by tapered end piece, lock core piece, and bolt, steel plug are unified into the integral body of not dismantling with them and back fork of bicycle, passes this two part with a rod iron again and realizes locking.But this device has such problem, and the invar plug is filled in the bolt duct dead, can't be fastening after the bolt generation is loosening, and very difficult when the car owner needs a lock to take off, rod iron need take off and be placed on inconvenience loss easily again in the special clip when opening.
The purpose of this utility model is that a kind of combined type lock bolt antiwithdrawal device will be provided, and it can be installed when lock is opened, demounting bolt, built-in bolt when the lock locking.
The utility model is to realize like this, divide tapered end seat and tapered end rotating disk two former tapered end piece partly, several countersunk screws hole is arranged on the tapered end seat, bolt passes the back and joins together with attached, car breeches pipe, the tapered end rotating disk has a through hole, rod iron therefrom passes the back by little one section plane of blocking the middle part of a screw, and rod iron can horizontally slip but get to come out.The tapered end seat is to connect like this with the tapered end rotating disk, one concave surface is arranged on the tapered end seat, one mesopore, little axle on the tapered end rotating disk pass mesopore and packing ring riveted joint afterwards the tapered end rotating disk can in concave surface, rotate and but carry to come out, one via hole is arranged on the tapered end rotating disk, just can aim at one by one with following several countersunk screws hole when dial rotation, bolt just connects with attached from the hole one by one.Rotating disk is that following bolt is blocked when lock is in the locking shape.Have one section breach on the tapered end rotating disk, the tapered end seat is equipped with a caging bolt in corresponding positions, and on it refilled after lock installs, it can be controlled rod iron and rotate in certain 90 degree together with rotating disk, lift rod iron when needing locking, caput is aimed at the lock core blind hole of opposite lock core piece; Rod iron withdraws to turn 90 degrees with car fork parallel direction behind the rim and hangs from above on the tapered end rotating disk when need opening, and caging bolt can guarantee the swing in the rim of rod iron body.The lock core piece is by the lock body of bullet lock and garden dish seat whole cast, on the dish seat of garden three countersunk screw holes are arranged, one in inboard two outsides, itself and attached, car breeches pipe can be joined together by bolt, there is a lock core blind hole lock core piece inboard, after rod iron passed blind hole realization locking, barred body just in time blocked half of inboard two screws, and these two bolts can't be dismantled.
The utility model only needs former tapered end piece is divided into two, former lock core is block-shaped to be become slightly, so structure is still simpler, its starting point built-in not shutting of bolt and at bolt, movable tapered end rotating disk and lock core piece particular design can the construction bolt demounting bolts, again can built-in bolt, rod iron horizontal position needs when the tapered end rotating disk can satisfy locking can satisfy the needs of rod iron vertical position when opening again.Convenience when the safety when caging bolt guarantees to open provides locking again.
The concrete structure of model utility is provided by following examples and accompanying drawing.
Fig. 1 is the utility model combined type lock bolt antiwithdrawal device assembling schematic representation.
Fig. 2 is that the utility model combined type lock bolt antiwithdrawal device tapered end seat connects part sectioned view partly with the tapered end rotating disk.
This device is divided into tapered end seat (3) and tapered end rotating disk (9) two parts to the tapered end piece, some is the tapered end seat (3) that several countersunk screws hole (4) is arranged, tapered end seat centre bit is equipped with a step hole (10), there is a concave surface (20) upper end, another partly is tapered end rotating disk (9), one through hole (18) is arranged at its top, rod iron (8) passes from the hole, the tapered end rotating disk has a center hole (19) to communicate with through hole (18), center hole has screw thread on (19), one has the little axle of screw (22) middle part of step that the screw thread (21) of joining center hole (19) is arranged, afterbody has the step of joining packing ring (23), pack into the center hole (19) of tapered end rotating disk (9) of the little axle of screw (22) blocks one section plane at rod iron (8) middle part, and rod iron (8) can horizontally slip and but get to come out.Step hole (10) back of the other end of the little axle of screw (22) being pierced into tapered end seat (3) rivets with packing ring (23).Tapered end rotating disk (9) can but be carried to come out in concave surface (20) in rotation like this, via hole (6) is arranged on the tapered end rotating disk (9), when tapered end rotating disk (9) rotates, via hole (6) can be aimed at one by one with the several countersunk screws hole (4) on the tapered end seat (3), bolt (7) from via hole (6) countersunk screw hole (4), pass with attached (1) on screw hole (2) link up, tapered end rotating disk (9) is the whole screws below can blocking when lock is in locked position of coupler.Have one section breach (5) on the tapered end rotating disk (9), after the lock installation is intact, on tapered end seat (3), load onto caging bolt (11) again, this bolt sticks in the breach (5), rod iron (8) and tapered end rotating disk (9) can only be rotated in 90 degree scopes, the direction of rod iron (8) is over against the lock core blind hole (14) on opposite when satisfying substantially horizontal, the afterbody that is pressed in rod iron (8) with the hand thumb is realized locking with in the caput jacking lock core blind hole (14) under the effect of dead bolt.Key inserts in the lockhole at lock core piece (16) middle part when needs are opened, rotate lockhole, rod iron (8) ejects under the inner spring action of lock core blind hole (14), with hand rod iron (8) along continuous straight runs is slided to a left side from the right side, with excellent tail toward pressing down, make rod iron (8) rotate 90 degree and be the direction that hangs down and hang with tapered end rotating disk (9) because the effect of caging bolt (11), rod iron when hanging down direction (8) but parallelly with the rear vehicle fork pipe can not spring into rim.Lock core piece (16) is by pin tumbler lock body and garden dish seat up-down structure whole cast, there are two countersunk screw holes (13) and a lock core blind hole (14) in dish inboard, lock core piece (16) garden, there is a countersunk screw hole in the dish outside, garden, the screw hole (12) that bolt (15) pierces on countersunk screw hole (13) and attached (17) links up, because lock core blind hole (14) is positioned at the centre in inboard two countersunk screw holes (13), so when lock is realized locking, rod iron (8) pierces into barred body in the lock core blind hole (14) and just in time keeps off some at inboard two bolts hole (13), and these two bolts can't be dismantled.
