the spring 3 is sleeved on the pressure lever 2 and is positioned between the annular blocking edge III and the annular blocking edge II; the upper end and the lower end of the spring 3 are respectively fixedly connected with the annular blocking edge III and the annular blocking edge II;
the movable clamping plate 8 is L-shaped, a through inverted U-shaped clamping groove 6 is formed in the front end of the movable clamping plate 8, the rear end of the movable clamping plate 8 is connected with the lower end of the connecting rod 5 through a connecting hole 9, a rotating shaft 7 is arranged between the front end and the rear end of the movable clamping plate 8, the rotating shaft 7 is matched with the second mounting hole 18, and the movable clamping plate 8 is rotatably connected with the first mounting piece 17 and the second mounting piece through the rotating shaft 7 and the second mounting hole 18; the inverted U-shaped clamping groove 6 is matched with the gear teeth.
When the handle 1 is pulled to the left side to the maximum rotation angle, the inverted U-shaped clamping groove 6 is abutted against the extension plate 11.
The movable clamping plate used in the prior art is shown in fig. 3, other structures and installation manners are the same as those of the invention, and in a large number of practical processes, the inventor of the invention finds that: in order to ensure that the movable clamping plate 21 can rotate around the rotating shaft 7, a gap needs to be left between the first mounting plate 17 and the movable clamping plate 21 and between the second mounting plate and the movable clamping plate 21, the gap exists, so that the movable clamping plate 21 and the gear teeth can not be completely aligned (the movable clamping plate 21 deviates to the left side or the right side of the gear teeth), when the braking is finished or the braking is released, because the movable clamping plate 21 and the gear teeth are in an incomplete alignment state, the movable clamping plate 21 can continuously apply outward thrust to the arc-shaped part (refer to the attached figure 1 in the description) on the left side of the mounting hole II 18 on the mounting piece I17 or the mounting piece II, so that the left arc-shaped part of the mounting plate I17 and the mounting hole II 18 on the mounting plate II are outwards turned and deformed towards two sides, when the deformation is enough, the movable clamping plate 21 can not be effectively clamped between wheel teeth, so that the traditional hand brake fails.
On the other hand, if the handbrake is used unnormally, for example, the handle is pulled when the pressing amount of the pressing rod 2 is insufficient, a large friction force exists between the movable clamping plate 21 and the gear teeth, under the action of the friction force, the front end of the movable clamping plate 21 is prone to deviating to the two sides of the gear teeth, the outwards-turning deformation amount of the arc-shaped part on the left side of the mounting hole two 18 on the first mounting plate 17 and the second mounting plate to the two sides is further increased, and when the deformation amount is sufficient, the traditional handbrake brake is failed.
The movable clamping plate 8 is an improvement on a movable clamping plate 21 in the prior art, the inverted U-shaped clamping groove 6 is arranged at the front end of the movable clamping plate 8, the bottom of the inverted U-shaped clamping groove 6 is clamped with the gear teeth for braking, the side wall of the inverted U-shaped clamping groove 6 can prevent the movable clamping plate 8 from deviating from the gear teeth and can be well aligned with the gear teeth in the braking process, and the structure can avoid the problems that an arc part on the left side of a mounting piece I17 and a mounting hole II 18 on the mounting piece II turns outwards towards two sides to cause destructive deformation, the movable clamping plate is not aligned with the gear teeth and the like to cause malfunction of a hand brake in the braking process in the use process.
One end, far away from the fan-shaped chuck 12, of the limiting plate is provided with a first mounting lug 10, and the first mounting lug 10 is provided with an oblong through hole.
The lower end of the fan-shaped chuck 12 is provided with an L-shaped connecting plate 13, the lower end of the L-shaped connecting plate 13 is provided with a second mounting lug 14, and the lower end of the second mounting lug 4 is provided with a circular through hole. The first mounting lug 10 and the second mounting lug 4 are used for being connected with other parts.
The working principle is as follows: the user applies downward pressure to the upper end of the pressure lever 2, the pressure lever 2 moves downwards in the handle 1, the spring 3 is compressed, along with the descending of the pressure lever 2, the connecting rod 5 is driven to push the movable clamping plate 8, the left end of the movable clamping plate 8 rotates clockwise, so that the inverted U-shaped clamping groove 6 is separated from the gear teeth on the fan-shaped chuck 12, then the handle 1 is pulled towards the right side, when the left side surface of the fan-shaped chuck 12 abuts against the limiting column 15, the user stops applying pressure to the pressure lever 2, the pressure lever 2 moves upwards in the handle 1 under the action of the spring 3, the left end of the movable clamping plate 8 is driven to rotate anticlockwise through the connecting rod 5, the inverted U-shaped clamping groove 6 is clamped into the gear teeth on the fan-shaped chuck 12, the braking is completed, when the hand brake needs to be released, downward pressure is applied to the upper end of the pressure lever 2, the pressure lever 2 moves downwards, along with depression bar 2's decline, drive connecting rod 5 and promote movable cardboard 8, make the left end of activity cardboard 8 carry out clockwise rotation, thereby make the teeth of a cogwheel on the type of falling U draw-in groove 6 and the fan-shaped chuck 12 break away from, then the user pulls handle 1 to the left side, when reacing suitable position, the user stops exerting pressure to depression bar 2, depression bar 2 is under spring 3's effect, rebound in handle 1, the left end that drives movable cardboard 8 through connecting rod 5 carries out anticlockwise rotation, the type of falling U draw-in groove 6 card is gone into on the teeth of a cogwheel on the fan-shaped chuck 12, the braking is relieved.
