Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1 to 3 This utility model provides an embodiment of a tension lock with an anti-vibration structure, comprising a lock body 1, which is the main body of the entire tension lock. A connecting plate 2 is rotatably connected to the top of the lock body 1, and a connecting ring 3 is slidably connected to the outside of the connecting plate 2 to provide additional stability and support. Multiple cavities 4 are formed inside the connecting ring 3, and springs 5 are fixedly connected inside the cavities 4 to accommodate the springs 5 and other components. A pressure plate 6 is fixedly connected to the other end of the spring 5 to provide elastic force. The pressure plate 6 is slidably connected to the inner wall of the cavity 4, allowing the pressure plate 6 to fit tightly against the inner wall of the cavity 4.
[0032] When the lock cylinder 9 moves, the pressure plate 6 is pressed by the spring 5, thus fitting tightly against the inner wall of the cavity 4. An elastic plate 7 is fixedly connected to the other side of the pressure plate 6. The bottom of the connecting plate 2 is fixedly connected to the lock cylinder 9. The locking or unlocking of objects is achieved by moving it up and down, and this plate is used to connect and secure the lock cylinder 9. It is rotatably connected to the lock body 1, allowing the lock cylinder 9 to move on it. The outer surface of the elastic plate 7 contacts the outer surface of the latch 10. When the lock cylinder 9 moves, the elastic plate 7 is subjected to pressure and squeezed to both sides, thereby increasing the stability of the lock cylinder 9.
[0033] The connecting plate 2 is externally threaded with a locking ring 11. The lock body 1 is internally equipped with an adjustment component that can adjust the position of the lock cylinder 9. The adjustment component includes a sliding plate 12, which is externally slidably connected to the inside of the lock body 1. The sliding plate 12 has a groove 13 inside. When the sliding pins 14 slide in the groove 13, they will drive the locking plate 15 to move together. Two sliding pins 14 are fixedly connected inside the groove 13. The side of the sliding pins 14 away from the groove 13 is fixedly connected to the locking plate 15. When the sliding pins 14 slide in the groove 13, they will drive the locking plate 15 to move together. The outside of the lock cylinder 9 engages with the outside of the locking plate 15.
[0034] When the sliding pin 14 slides in the groove 13, the locking plate 15 moves with the sliding pin 14, thereby changing the position of the lock cylinder 9. The outer side of the locking plate 15 is slidably connected to the inner wall of the lock body 1. The connecting plate 2 has two adjustment grooves 21 inside. The outer side of the locking plate 15 engages with the inner wall of the adjustment groove 21. When the locking plate 15 contacts the adjustment groove 21, it will slide outward due to inertia and engage with the inner wall of the adjustment groove 21, thereby fixing the lock cylinder 9 in a specific position.
[0035] Reference Figure 4 The top of the connecting plate 2 is provided with a limiting component, which can limit the lock cylinder 9. The limiting component includes two locking rods 10. The locking rods 10 are fixedly connected to the outside of the lock cylinder 9. When the lock cylinder 9 moves, the locking rods 10 will slide along the limiting groove 8, thereby limiting the movement range of the lock cylinder 9. The top of the connecting plate 2 is provided with a placement groove 16. The bottom of the placement groove 16 is fixedly connected with a protrusion 17. When an external tool is inserted into the placement groove 16 and the protrusion 17 is rotated, the lock cylinder 9 will also rotate accordingly.
[0036] A directional indicator 18 is fixedly connected to the bottom of the connecting plate 2 to indicate the rotation direction of the lock cylinder 9. This helps the user to operate the lock correctly. The outer side of the locking rod 10 engages with the inner wall of the limiting groove 8. When the locking rod 10 slides along the limiting groove 8, it restricts the range of movement of the lock cylinder 9. A screw is fixedly connected to the bottom end of the lock body 1 to support the abutment plate 19 and provide an adjustable interface to change the position of the abutment plate 19. The abutment plate 19 is slidably connected to the outer side of the screw for contact with the object to be locked.
[0037] When nut 20 is tightened, the abutment 19 is pushed toward the object and locked in place. The screw has an external threaded connection to nut 20, which is used to adjust the position of the abutment 19 and lock the object. When nut 20 is tightened, it pushes the abutment 19 toward the object and locks it in place; when nut 20 is loosened, the abutment 19 can move freely and release the object.
[0038] Working principle: First, place the lock body 1 in a suitable position, then put the external tool into the placement slot 16, and then use the protrusion 17 to rotate the lock cylinder 9. At this time, the rotation position can be determined by the direction of the directional mark 18. As the lock cylinder 9 moves, the locking rod 10 will squeeze the elastic plates 7 on both sides. The elastic plates 7 are forced to press the pressure plates 6 on both sides. At this time, the pressure plates 6 slide towards the inner wall of the cavity 4, causing the spring 5 to be compressed. When the spring 5 is compressed, it will generate a reaction force on the pressure plates 6, making the elastic plates 7 and the locking rod 10 fit more tightly. At the same time, the spring 5 and the elastic plates 7 can absorb the external force generated when the lock cylinder 9 rotates, thereby preventing the lock cylinder 9 from breaking when the force is too great.
[0039] As the lock cylinder 9 enters the interior of the lock body 1 and continues to move, it comes into contact with the outside of the locking plate 15. At the same time, the locking plate 15 will drive the sliding column 14 to slide on the inner wall of the slide groove 13, so that the locking plate 15 fits against the inner wall of the lock body 1, fixing the lock cylinder 9. Then, the abutment plate 19 is brought into contact with the object to be locked, and the nut 20 is turned to lock the abutment plate 19 to the outside of the object. The protrusion 17 is turned in the opposite direction, which drives the lock cylinder 9 to move upward. At this time, the sliding plate 12 will also move upward with the lock cylinder 9. When the locking plate 15 contacts the adjustment groove 21, the locking plate 15 slides outward due to inertia and engages with the inner wall of the adjustment groove 21. At this time, the lock cylinder 9 separates from the locking plate 15, and the lock cylinder 9 can be taken out.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
