Description

Technical Field

[0001] This utility model belongs to the field of cable tie technology, and particularly relates to a self-locking, shock-resistant, and anti-loosening cable tie. Background Technology

[0002] Cable ties are a commonly used binding and securing tool, widely used in various fields.

[0003] In some complex vibration environments, such as the internal wiring harness fixing of vehicles and the pipeline organization of industrial equipment, ordinary cable ties are prone to loosening due to vibration, causing the bundled objects to loosen and even causing safety hazards. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by proposing the following technical solution:

[0005] The self-locking shockproof and anti-loosening cable tie includes a cable tie body and a locking head, wherein anti-slip teeth are evenly arranged on the cable tie body along the length direction;

[0006] The lock head has an insertion cavity for inserting the cable tie body, and the inner wall at the bottom end of the insertion cavity has a locking tooth that engages with the anti-slip tooth.

[0007] A movable plate is provided above the inner wall of the insertion cavity. A pressure plate is fixedly connected to the bottom of the movable plate, and a connecting rod that penetrates the outer wall of the lock head is connected to the top of the movable plate. A limiting plate is provided at the top of the connecting rod.

[0008] Elastic elements are connected to both sides of the top of the movable plate, and the top of the elastic elements is fixed to the inner wall of the lock head;

[0009] The movable plate is symmetrically provided with sliders on both sides, and the inner wall of the lock head is provided with a slide rail that slides with the sliders.

[0010] As a preferred embodiment of the above technical solution, the pressure plate abuts against the smooth surface of the cable tie body under the action of gravity or the elastic force of the elastic element.

[0011] As a preferred embodiment of the above technical solution, the elastic element is a compression spring, a sheet, or an elastic rubber column.

[0012] As a preferred embodiment of the above technical solution, the surface of the pressure plate that contacts the cable tie body is provided with anti-slip texture or rubber layer.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this application, the anti-slip teeth and the locking teeth form a mechanical engagement to provide basic locking force. Then, the pressure plate continuously presses the cable tie body with gravity or elastic elements to suppress the micro-displacement between the teeth caused by vibration, thus achieving double locking to prevent loosening.

[0015] In this application, a linear guide mechanism is formed by a slider and a slide rail to prevent the pressure plate from swaying, and the travel of the movable plate is limited by a limit plate to avoid overload failure, thereby improving the seismic stability.

[0016] In this application, when the plate is in a vertical position, gravity drives it to press down. When the plate is not in a vertical position, the elastic element provides compensating elastic force to ensure that the clamping force does not decrease and to guarantee full-angle self-adaptation.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the self-locking shockproof and anti-loosening cable tie includes a cable tie body 1 and a locking head 3. Anti-slip teeth 2 are evenly arranged along the length direction on the cable tie body 1. Its characteristic is that:

[0023] The lock head 3 has an insertion cavity 4 for inserting the cable tie body 1. The inner wall of the bottom end of the insertion cavity 4 has a locking tooth 5 that engages with the anti-slip tooth 2. After the cable tie body 1 is inserted into the insertion cavity 4 of the lock head 3, the anti-slip tooth 2 and the locking tooth 5 engage to form the main lock.

[0024] A movable plate 7 is provided on the upper part of the inner wall of the insertion cavity 4. The bottom of the movable plate 7 is fixedly connected to the pressure plate 6, and the top is connected to the connecting rod 8 that penetrates the outer wall of the lock head 3. A limiting plate 9 is provided at the top of the connecting rod 8.

[0025] The top two sides of the movable plate 7 are connected to elastic elements 10, and the top of the elastic element 10 is fixed to the inner wall of the lock head 3.

[0026] The movable plate 7 has symmetrical sliders 11 on both sides, and the inner wall of the lock head 3 has a slide rail 12 that slides with the sliders 11; the sliders 11 on both sides of the movable plate 7 slide in a straight line along the slide rail 12 to prevent the pressure plate 6 from tilting.

[0027] like Figure 1 and Figure 2 As shown, the pressure plate 6 abuts against the smooth surface of the cable tie body 1 under the action of gravity or the elastic force of the elastic element 10; gravity drives the movable plate 7 to move down, causing the pressure plate 6 to press tightly against the surface of the cable tie body 1; the elastic element 10 is a compression spring, a spring sheet, or an elastic rubber column; the elastic element 10 generates a restoring force under pressure, pushing the movable plate 7 to keep the pressure plate 6 pressed; the surface of the pressure plate 6 in contact with the cable tie body 1 is provided with anti-slip texture or rubber layer.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
