Description
The utility model relates to a kind of bicycle lock, particularly a kind of two hitching post locks that are applicable to bicycle, vehicle using motor.
Existing single throw lock, when being installed on the locking of car fork, the horizontal spoke that stops of locking bolt must not rotate wheel.But locking bolt is easy to be prized transposition and moves, so its safety performance is relatively poor, its defective system because of Vehicle lock structure unreasonable due to.
The purpose of this utility model is to overcome above-mentioned defective of the prior art, provides that a kind of lock body is firm, locking bolt is difficult for pulling, safe and reliable two hitching post locks, to satisfy social needs.
Task of the present utility model is finished according to following technical proposals:
This pair of hitching post lock, system is by lock body, locking bolt, tapered end, back-moving spring, fixed screw, fixed head is constituted by assembly, the as a whole foundry goods of its lock body, screw hole and hitching post hole are run through lock body from positive to the back side, lockhole that the lock body side is offered contain put tapered end and stretch into lock body at right angles crossing with a hitching post hole, side is provided with a dowel hole in addition, the lock body back side is provided with cancave cambered surface between the two-screw hole, locking bolt is U type shape, the thin footpath of portion constitutes circular step with wide section joint, rear portion before two hitching posts, and be respectively equipped with radially the lock slots and the axial locating slot of side on two wide sections, tapered end is made of lock core and cylindric stem stem, the afterbody of this stem stem have with the hitching post wide section outside footpath and the arc that is complementary of lock slots size lack.
Fixed head is one, and two ends are straight and the middle part is the plate of concave arc, and engrave on its two sides flat segments plate face with lock body on the equidistant isometrical screw thread of two screw holes hole that spins.
Screw hole is furnished with the protection plug of plug envelope.
Description of drawings of the present utility model:
Fig. 1 is the overall diagram of this pair hitching post lock;
Fig. 2 is the rear elevation of the lock body of this pair hitching post lock;
Fig. 3 is the structure chart of this pair hitching post lock locking bolt;
Fig. 4 is the partial cross-sectional view of this pair hitching post lock.
Among the figure: lock body 1, locking bolt 2, fixed screw 3, fixed head 4, protection plug 5, tapered end 6, hitching post hole 7, screw hole 8, back-moving spring 9, circular step 10, lock slots 11, stem stem 12, locating slot 13, tapered end hole 14.
The utility model will elaborate with embodiment in conjunction with the accompanying drawings.
The two hitching post locks of this kind are made of by critical piece lock body 1, locking bolt 2, fixed screw 3, fixed head 4, tapered end 6 and back-moving spring 9 shown in accompanying drawing 1 to 4.Lock body 1 as a whole foundry goods, its front offer respectively screw hole 8 and hitching post hole 7 each two in arranging up and down, and run through lock body 1 to the back side.One of lock body 1 side offers contains the tapered end hole 6 put tapered end hole 14, this tapered end hole 14 stretch into lock body 1 and with one of nearest hitching post hole 7 right angle intersections.Locking bolt 2 is U type shape, and its two hitching posts are 7 insertion lock bodies 1 from the hitching post hole, and hitching post is anterior, and the two joint constitutes a circular step 10 for thin diameter section, rear portion are wide section, and this circular step 10 is located on 9 pushing tows of back-moving spring on the thin diameter section.Two wide sections of hitching post touch in subsides that the hitching post top of stem stem 12 is corresponding to be provided with a lock slots 11 radially, and lateral column is provided with the locating slot 13 of an axial side on one's body outside another root hitching post.It is to be made of lock core and cylindric stem stem 12 that culvert places the tapered end 6 in tapered end hole 14.Stem stem 12 backs down keyhole, intension pellet shot from a slingshot and pellet shot from a slingshot spring group, its afterbody have one with locking bolt 2 wide sections outside the footpath radian and on the arc of lock slots 11 size match offered lack, be formed at the protruding tongue that embeds lock slots 11 lock-out state under just, makes the scalable slippage of hitching post when opening on the scarce applying hitching post of rotation backarc thereby make it afterbody.Lock body side in addition embeds in the axial location groove 13 of side on the hitching post from the affixed alignment pin of fixed pin holes, makes the complete and qualification locking bolt aperture of locking bolt 2 and lock body 1 assembly.
The fixed head 4 of this pair bolt lock is one, and two ends are straight and the middle part is the plate of concave arc shape, and engrave on its two flat segments plate face with lock body 1 on two screw holes, the 8 equidistant isometrical and screwed holes that spin.When this pair hitching post lock passes the car that spins fixed head 4 and be assemblied in bicycle, vehicle using motor when sticking with fixed screw 3 from screw hole 8, car is pitched just by concave arc on lock body 1 back side and the opposed ring shape fixed clamp that is of the concave arc part on the fixed head 4, and spins fixing by two pieces of fixed screws 3.In the recessed screw hole 8 of the nut of fixed screw 3, its outer available protection plug 5 plug envelopes are prevented to revolve unloads, and is another security measures.
The locking of the two hitching post locks of this kind with open in the summary of situation movingly of parts:
Locking: will push away before the locking bolt 2, circular step 10 compressing back-moving springs 9 retractions of hitching post, when the lock slots on the hitching post 11 moves to, formerly under opening, lack stem stem 12 on the applying hitching post with arc, its protruding tongue promptly changes in the lock slots 11 and embedding ends locking bolt 2, make lock enter lock-out state, its two hitching posts stretch into and stop between the wheel bar and move in turn.
Open: insert lockhole with key and rotate, stem stem 12 rotations make protruding tongue migrate out lock slots 11, locking bolt 2 is retired under the effect of back-moving spring 9 pushing tow circular steps 10, arc lacks the state that is in again on the applying hitching post, locking bolt 2 promptly returns to the enable possition because of the qualification that cooperates of side locating slot 13 with alignment pin.
The utility model with lock of the prior art relatively is total to advantage and is:
The as a whole foundry goods of lock body is solid firm; Two hitching posts of U-shape lock bolt stretch between the wheel bar when locking and block Wheel, insurance is reliable; Concave arc counter-rings on lock body concave arc and the fixed head is enclosed fixed clamp, in addition the spiral shell of fixed screw Cap embeds screw hole and the plug envelope has the protection plug, so lock body is again not quick detachable.
