Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
The first embodiment is as follows:
the utility model relates to a self-adaptive vehicle lock, which comprises a fixing piece, a connecting rod 3, a lock body 1 and a lock rod 22; the two ends of the connecting rod 3 are arranged on the bicycle frame through fixing parts, the lock body is arranged on the connecting rod 3, and the lock rod 22 is arranged on the lock body; the lock body 1 is provided with a lock shell 11, an oblique tongue 12 and a key hole 6, and the oblique tongue 12 can extend out of the lock shell 11; the lock rod 22 is L-shaped and comprises a long arm and a short arm which are vertical to each other, the lock rod 22 is hinged on the lock shell through a corner, and a torsional spring 21 is arranged at the joint; when in an unlocking state, the long arm is clamped and positioned with the latch bolt 12; in the locking state, the short arm is clamped and positioned with the latch bolt 12, and the long arm is inserted into the wheel hub to lock the vehicle.
The short arm is provided with a notch 23 matched with the inclined tongue 12, and after the lock rod 22 rotates through the inclined tongue 12, the notch 23 is clamped on the inclined tongue 12.
As shown in fig. 1-3, in the using process, the lock body is fixed on the connecting rod 3, the lock rod 22 has a simple structure, the lock rod 22 is in an inverted L shape, when the lock is not locked, the long arm of the lock rod 22 faces downwards, the short arm of the L can be pressed, the rotating device rotates clockwise, and the torsion spring can rebound the lock rod to the original state anticlockwise when the latch bolt 12 contracts; the latch bolt 12 is tightly attached to the middle of the left side of the long arm of the lock rod 22, and the inclined surface faces to the left, so that when the rotary lock rotates clockwise, the latch bolt 12 is forced to contract, the rotation of the latch bolt cannot be influenced, but the latch bolt is popped up and clamped when the short arm of the rotary lock rod faces downwards, the lock rod is forced to stop at the original position, the short arm faces downwards, the long arm faces to the right, and the long arm facing to the right can clamp the axle of the bicycle, so that the function of locking the bicycle is achieved. When the latch tongue 12 is retracted, the lock lever returns to its original position due to the elastic restoring force provided by the torsion spring. The lock hole 6 is positioned above the vehicle lock main body, so that a user can conveniently unlock the vehicle lock, and the vehicle lock is not different from an ordinary lock cylinder and can rotate behind a key inserted and matched with the lock cylinder.
Example two:
the further improvement of the embodiment is that: the fixed piece is provided with a positioning device 4; the positioning devices 4 are respectively and symmetrically arranged at two ends of the connecting rod 3; and is fixed on the frame; the positioning device 4 comprises an upper clamp 41 and a lower clamp 42; after the upper clamp 41 and the lower clamp 42 are clamped, a hole 43 capable of accommodating the frame is formed in the middle of the upper clamp; the upper clamp 41 is provided with a groove 411 and a lock hole 412; the lower clip 42 is provided with a bump 421 capable of being sleeved in the groove 411 and a return spring 422 abutting against the bump 421 and the bottom of the groove 411; the protrusion 421 is hollow and has a control line 424 and a latch 423 adapted to the lock hole 412; one end of the control wire 424 is connected with the bolt 423; the other end passes through the connecting rod 3 to be connected with the lock body 1.
As shown in fig. 4-9, the whole lock is substantially I-shaped, the positioning device 4 is arranged at two ends of the connecting rod 3, the two ends have the same structure, each end is composed of an upper clamp and a lower clamp, the whole external shape of the upper clamp and the lower clamp is rectangular, the middle part of the upper clamp and the lower clamp is hollow and circular, the upper clamp and the lower clamp are fixed on the frame after being clamped, a groove with a cylindrical space is reserved inside the upper clamp, and a lock hole 412 is reserved at the upper right of the cylindrical space for facilitating the lock tongue 423. The upper clamp and the lower clamp are connected by a hollow convex block 421, the diameter of the convex block is slightly smaller than that of the groove, the uppermost end of the convex block is in a flat cake shape, the diameter of the convex block is equal to the cylindrical space in the upper clamp, and a return spring is arranged between the bottom of the convex block and the bottom of the groove 411, so that the convex block 421 moves up and down and has a certain moving range. The lug is hollow and is provided with a control line and a bolt 423, a spring is arranged between the control line and the bolt 423, and the bolt passes in and out of the lug through the control line; the inside passage and the lock core unit connection of lock body unit are connected to another of control line, when the lock core rotated 180 left, the control line just can be pulled backward, make the spring bolt shrink, can make and go up to press from both sides, press from both sides separately down, when the lock core got back to the normal position, the spring bolt can be because the spring's the reason stretches out outward, contact the lockhole when the spring bolt, the spring bolt stretches out completely, and blocked in the original place, go up to press from both sides, press from both sides the block down, and can't beat, until the lock core carries out 180 operations left, so the spring bolt plays the effect of pinning the clip, do not let it loosen. The lower clamp is fixed with the convex block, a space similar to a round cake shape is further arranged in the lower clamp and used for a universal joint connected with the connecting rod, and the universal joint is in the round cake shape, so that the joint can have a plane rotating angle, the lock body unit cannot rotate around to lose functions after the clamp is fixed in a universal mode.
During installation, the clips on the two sides are buckled on the frame after the angles are selected and then pressed, and at the moment, the lock tongue can touch the lock hole and then clamp the clips to fix the bicycle lock.
When the lock is used, the long arm of the lock rod is pressed downwards, the latch bolt can be ejected into the lock shell until the short arm of the lock rod passes through the latch bolt, the latch bolt is ejected, and the notch is clamped on the latch bolt; at this point the bicycle is locked.
The internal structure of the lock body is the same as that of a door lock, and the internal control system is opened through a key, so that the movement of the latch bolt on the lock tongue is controlled. The utility model discloses simple structure, the cost is lower, and application scope is wide, convenient to use.
