Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Example 1: Please refer to Figures 1 to 3 The utility model provides a technical solution: a retractable lock, comprising a lock box 1 and a lock tongue 2 slidably mounted at one end of the lock box 1, an auxiliary slide groove 3 is provided on one side of the lock box 1, an auxiliary slide button 4 is slidably mounted on the inner side of the auxiliary slide groove 3, the auxiliary slide button 4 is fixedly mounted on one side of the lock tongue 2, a telescopic slide groove 13 is provided on the inner side of one end of the lock tongue 2, a telescopic spring 12 is fixedly mounted on one end of the inner side of the telescopic slide groove 13, a telescopic slider 14 is fixedly mounted on one end of the telescopic spring 12, the telescopic slider 14 is slidably mounted in the telescopic slide groove 13, an active slide 5 is fixedly mounted on one side of the telescopic slider 14, one side of the active slide 5 is connected to the lock box 1 through a telescopic mechanism, and the auxiliary slide button 4 is slidably mounted on the inner side of the auxiliary slide groove 3, and the lock tongue 2 is moved by sliding. The telescopic slide 13 and the telescopic slider 14 move on the active slide 5, and the auxiliary slide button 4 is released to push the lock tongue 2 to reset through the elastic force of the telescopic spring 12; the side surface of one end of the lock tongue 2 is set as an inclined surface, and the auxiliary slide button 4 and the telescopic slider 14 are both slidably installed on the lock tongue 2, which is convenient for the lock tongue 2 to stably slide and plug in the switch when in use. The lock box 1 includes a box body 15 and a box cover 16, and the inner four corners of the box body 15 are provided with screw holes. The box cover 16 is fixedly installed on the box body 15 by screws and screw holes. One side of the lock tongue 2 is connected to the telescopic mechanism, and the other side of the lock tongue 2 is slidably installed on one side of the auxiliary slide groove 3, which is convenient for the lock tongue 2 to stably slide in the lock box 1. A heat dissipation port is provided on the outer surface of one end of the lock box 1, which is convenient for internal heat dissipation when in use.
[0021] From the above description, it can be seen that the utility model has the following beneficial effects: when in use, the lock tongue 2 is connected to the active slide 5 through the telescopic spring 12 and the telescopic slide groove 13. When the electric drive component fails, the auxiliary slide button 4 can be used to drive the lock tongue 2 to telescopically slide and open on the active slide 5. In the event of a failure, it is more convenient to open the box without disassembling it, and it can be repaired later.
[0022] Example 2: Please refer to Figures 1 to 3As shown, on the basis of Example 1, the utility model provides a technical solution: the telescopic mechanism includes a moving screw 8 rotatably mounted in the lock box 1 through a bearing and a driving motor 11 fixedly mounted at one end of the lock box 1, one end of the moving screw 8 is sleeved with a moving nut 7, one side of the moving nut 7 is fixedly mounted with a mounting frame 6, one end of the mounting frame 6 is fixedly connected to the active slide 5, and the other end of the moving screw 8 is connected to the output shaft of the driving motor 11, and the driving motor 11 drives the moving screw 8 to drive the moving nut 7 and the mounting frame 6 to move, thereby driving the lock tongue 2 to move and open and close the motorcycle box; one end of the moving screw 8 is fixedly mounted with a transmission worm gear 10, one side of the transmission worm gear 10 is meshed with a transmission worm 9, the transmission worm 9 is rotatably mounted in the lock box 1 through a bearing, one end of the transmission worm gear 9 is fixedly connected to the output shaft of the driving motor 11, and the drive motor 11 can stably drive the moving screw 8 to rotate through the transmission of the transmission worm gear 10 and the transmission worm gear 9.
[0023] By adopting the above technical solution, when in use, the mounting frame 6 and the active slide 5 are driven to move by the transmission of the moving nut 7 and the moving screw 8, thereby driving the lock tongue 2 to slide and switch, and the self-locking effect of the transmission worm 9 and the transmission worm wheel 10 makes the lock tongue 2 more stable when telescopically moving.
[0024] The working principle and use process of the utility model are as follows: when in use, the lock box 1 is installed on the inner side of the motorcycle box body, and is fixed on the box cover by the lock tongue 2, and the lock box 1 is hidden on the outer side of the motorcycle box body through a lock cover. When in use, the drive motor 11 drives the moving screw 8 to rotate through the transmission of the transmission worm 9 and the transmission worm wheel 10, and the moving screw 8 drives the moving nut 7 and the mounting frame 6 to move, thereby driving the lock tongue 2 to move the switch. After long-term use, when the drive motor 11 fails and cannot drive the lock tongue 2 to move, it is only necessary to open the lock cover on the outer side of the motorcycle box body with a key, and then slide the auxiliary slide button 4 to drive the lock tongue 2. The lock tongue 2 moves on the active slide frame 5 through the telescopic slide groove 13 and the telescopic slider 14, so that one end of the lock tongue 2 is removed from the box cover, and then the items can be taken out, and the components in the lock box 1 can be inspected later.
