[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0017] The utility model provides Figure 1-3 A security equipment cable fastening device shown in the figure includes a fastening ring 1 and two extension sleeves 2. The extension sleeves 2 are nested at both ends of the fastening ring 1. An annular groove 8 is opened on the inner wall of the fastening ring 1. Cross plates 10 are nested on both sides of the annular groove 8. An inflatable rubber ring 11 is fixed between the two cross plates 10, and the inflatable rubber ring 11 is placed inside the annular groove 8.

[0018] Specifically, by providing an inflatable rubber ring 11 inside the fastening ring 1, the connecting end of the security equipment cable can be tightly contacted and fixed, and the cooperation of the two extension sleeves 2 can increase the protection length of the connecting end, and the locking plates 3 provided at the ends of the two extension sleeves 2 can further lock the cable, thereby improving the tightness of the cable joint and reducing the problem of poor contact due to excessive tension at the cable joint.

[0019] according to Figure 1 , Figure 2 and Figure 3 As shown, the ends of one end of the two extension sleeves 2 are fixedly provided with integral and evenly distributed locking plates 3, and the surface of the locking plates 3 is provided with evenly distributed anti-slip patterns.

[0020] Specifically, the provision of the locking piece 3 can assist in locking, thereby improving the cable tightening effect.

[0021] A card slot 7 is provided on both side walls of the other end of the two extension sleeves 2, and blocks 12 adapted to the card slot 7 are fixedly provided on both sides of the bottom end of the cross plate 10. The card block 12 is engaged with the card slot 7, and the side walls of the two card slots 7 are fixedly provided with limiting protrusions.

[0022] Specifically, the maximum extension length of the extension sleeve 2 is controlled by setting the limiting protrusion. When the limiting protrusion moves to the side wall of the annular groove 8, the extension sleeve 2 cannot move again.

[0023] Threaded push rods 4 are threadedly connected to both sides of the inner wall of the annular groove 8 , and the ends of the two threaded push rods 4 are rotatably connected to the center of the corresponding horizontal plate 10 .

[0024] Specifically, the threaded push rod 4 is rotated to push the horizontal plate 10 to move, and the horizontal plate 10 moves so that the blocks 12 on both sides of the bottom end of the horizontal plate 10 are inserted into the inside of the slot 7, thereby locking and fixing the extension sleeve 2.

[0025] An air filling hole 5 is provided at the top of the fastening ring 1 , and the bottom of the air filling hole 5 is connected to the air inlet end of the air-filled rubber sleeve 11 through a connecting hose 9 .

[0026] Specifically, the inflatable rubber sleeve 11 can be inflated conveniently through the inflation hole 5. The inflatable rubber sleeve 11 is inflated and expanded to squeeze and tighten the connection part, thereby improving the tightness of the cable connection and reducing the problem of excessive tension at both ends of the cable causing it to fall off.

[0027] A sealing plug 6 is nested inside the inflation hole 5 , and a sealing ring is sleeved on the surface of the sealing plug 6 .

[0028] Specifically, the inflation hole 5 is sealed by the sealing plug 6 to prevent the gas filled into the inflation rubber sleeve 11 from flowing out.

[0029] Working principle of the utility model: when the cable fastening device is used to fasten the connection part of the cable, the fastening ring 1 is firstly nested in the cable joint part, and then the extension sleeve 2 is pulled outward, and when the limiting protrusion on the side wall of the card slot 7 contacts the inner wall of the annular groove 8 and the extension sleeve 2 cannot be pulled, it stops, and at this time, the locking piece 3 at the end of the extension sleeve 2 is manually pressed by a fastening tool (pliers) to make the locking piece 3 closely contact with the cable surface;

[0030] Then, the threaded push rods 4 on both sides are manually rotated to push the movement of the cross plate 10 through the threaded push rods 4. The movement of the cross plate 10 makes the block 12 engage with the slot 7 to further fix the two extension sleeves 2. Then, the sealing plug 6 is pulled out and inserted, and the inflatable rubber ring 11 is inflated by an external air pump. The cable connection is further squeezed and fixed by the inflation of the inflatable rubber ring 11, thereby improving the tightness of the cable connection joint.
