Abstract
Description
Technical Field
[0001] This utility model relates to a fastening device, specifically a cable fastening device for security equipment, belonging to the field of security accessories technology. Background Technology
[0002] Currently, in the security field, real-time monitoring of images is mainly achieved by installing cameras to improve security performance. When installing security cameras, due to the different locations of the cameras, cables need to be installed to connect multiple security cameras. During installation, the two cables need to be connected, and in order to improve the firmness of the cable connection, the cable joints need to be tightened.
[0003] A cable fastening device for security equipment disclosed in Chinese Patent Application Publication CN222884323U describes a method for fastening cable connections. First, a fastening ring is nested within the cable connector. Then, the extension sleeve is pulled outwards. The process stops when the limiting protrusion on the sidewall of the slot contacts the inner wall of the annular groove, preventing further pulling. At this point, a fastening tool (pliers) is used to press the locking plate at the end of the extension sleeve, ensuring a tight contact between the locking plate and the cable surface. Next, the threaded push rods on both sides are manually rotated, pushing the horizontal plate to move. This movement engages the locking block with the slot, further securing the two extension sleeves. Afterwards, a sealing plug is inserted and removed, and an external air pump inflates the rubber sleeve. The inflation of the rubber sleeve further compresses and secures the cable connection, improving the tightness of the cable connector.
[0004] The solutions in the above patents can lock the cable, improve the tightness of the cable joint, and reduce the problem of poor contact caused by excessive tension at the cable joint. However, the device requires fastening tools and an air pump, and also requires manual rotation of the threaded push rods on both sides. This process is cumbersome and makes it difficult to fasten the cable quickly, causing inconvenience to people.
[0005] Therefore, a cable fastening device for security equipment is proposed here. Utility Model Content

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0024] Please see Figures 1-4 The present invention proposes the following implementation scheme: a cable fastening device for security equipment, including a fastening sleeve 1, and a fastening component 2 provided on the fastening sleeve 1.
[0025] An insulating sleeve 102 is fixed to the inner wall of the fastening sleeve 1, and the insulating sleeve 102 is located in the middle of the fastening sleeve 1, which can protect and insulate the connection of the cable.
[0026] Please refer to this carefully. Figure 3 and Figure 4 The fastening assembly 2 includes a threaded ring 201 threaded to the outer surface of the fastening sleeve 1 and a plurality of movable rods 203 slidably connected to the inner wall of the outer side of the fastening sleeve 1. The bottom surface of the threaded ring 201 near the movable rod 203 has an inclined groove 202. A ball 204 is installed at the top of the movable rod 203, and the top of the ball 204 abuts against the inner wall of the inclined groove 202. An arc-shaped clamping plate 206 is fixed to one end of the movable rod 203 inside the fastening sleeve 1. A telescopic spring 205 is sleeved on the outer surface of the movable rod 203, and the two ends of the telescopic spring 205 are respectively fixed to the fastening sleeve 1 and the side of the arc-shaped clamping plate 206 that are close to each other.
[0027] By rotating the threaded ring 201, it can move on the outer surface of the fastening sleeve 1. While the threaded ring 201 moves, it can squeeze the ball 204 on the moving rod 203 through the inclined groove 202, so that the moving rod 203 moves along the limiting groove 101 on the fastening sleeve 1. The moving rod 203 can drive the arc-shaped clamping plate 206 to move. The arc-shaped clamping plate 206 can clamp and fix the connection of the cable, so that the connection of the cable in the fastening sleeve 1 can be squeezed and fixed quickly and conveniently without the use of tools, thereby improving the tightness of the cable connection joint.

[0032] A guide rod 207 is slidably connected to the inner wall of the hole on the fastening sleeve 1, and one end of the guide rod 207 is fixed to the side of the arc-shaped clamping plate 206 near the moving rod 203, which can further limit and guide the movement of the arc-shaped clamping plate 206.
[0033] In use, the fastening sleeve 1 is fitted onto the cable connector, passing between the two arc-shaped clamping plates 206. Rotating the threaded ring 201 allows it to move on the outer surface of the fastening sleeve 1. Simultaneously, the threaded ring 201 compresses the balls 204 on the moving rod 203 via the inclined groove 202, causing the moving rod 203 to move along the limiting groove 101 on the fastening sleeve 1. The moving rod 203 then moves the arc-shaped clamping plates 206, which clamp and fix the cable connection, thereby enabling… Without using tools, the connection of the cable inside the fastening sleeve 1 can be quickly and easily squeezed and fixed, improving the tightness of the cable connection joint. At the same time, the movement of the arc-shaped clamping plate 206 can stretch the telescopic spring 205, causing it to generate a corresponding tension. When it is necessary to remove the fastening sleeve 1, the compression of the ball 204 and the moving rod 203 can be released by rotating the threaded ring 201 in the opposite direction. At this time, the arc-shaped clamping plate 206 will reset under the tension of the telescopic spring 205, thereby driving the moving rod 203 and the ball 204 to reset, making it convenient for the next use.
