Description

Technical Field

[0001] The utility model belongs to the technical field of weak current construction, in particular to a wire end fixing device. Background Art

[0002] Generally, the lines that transmit signals are called weak current lines. In weak current construction, the most complicated work is wiring. Although wireless network cards can meet the network needs of most people, in some server operations, network cables are still the most stable choice. When wiring network cables, it is generally necessary to bundle the cables tightly and then lay them in the already laid bridge.

[0003] When wiring the network cable, the cable is on the ground, while the bridge is in the air, and the cables are scattered, so the cable ends need to be fixed, otherwise the cable will be lost. At the same time, because the bridge is generally made of metal and there may be other obstacles inside, the cable ends need to be protected, otherwise dust and other substances may enter the cable sheath, affecting the subsequent connection of the crystal head, and causing damage to the cable sheath in severe cases.

[0004] Among them, it was found through work that the common way to fix the cable ends is to wrap the cable ends with tape, or to tie the cable ends to the ends of PVC pipes for wiring operations. The above operations are easy to leave glue marks when fixing the cables. During the movement of the cable ends, friction occurs between the cable bridge, causing the tape to break and the cable to be lost. Therefore, a device is designed that is convenient for clamping the cables and has the function of protecting the cables. Utility Model Content

[0005] The purpose of the present utility model is to provide a wire end fixing device in order to solve the above-mentioned problem.

[0006] The technical solution adopted by the utility model is as follows: a wire end fixing device, wherein a connecting plate is integrally provided inside a hollow tube, a connecting hole is provided on the surface of the connecting plate, a screw rod passes through the connecting hole and is connected to a nut, a clamping structure for clamping the cable is provided on the outside of the hollow tube, and a protective structure for protecting the cable end is movably connected inside the hollow tube;

[0007] The clamping structure includes: a sleeve and a first air bag;

[0008] A sleeve is fixedly installed on the outside of the hollow tube, and a first airbag is embedded in the inner wall of the sleeve;

[0009] The protective structure includes: traction head, plug column, second air bag, screw rod;

[0010] The hollow tube is movably connected with a plug post, the outer wall of the plug post is embedded with a second air bag, and the tail of the plug post is fixedly installed with a screw rod;

[0011] The plug post head is integrated with a traction head, the traction head is hemispherical, and a hook is integrated in the center; the traction head is integrated with a second mortar-shaped groove around it, and the sleeve is integrated with a first mortar-shaped groove around it.

[0012] There are several first mortar-shaped grooves and second mortar-shaped grooves, which are arranged in a ring array, and balls are installed inside them for rolling.

[0013] Wherein, the inner diameter of the hollow tube gradually increases from one end to the other end.

[0014] Among them, the sleeve and the traction head are both nested with valve nozzles, and the valve nozzles are connected to the first airbag and the second airbag through pipelines.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In the utility model, an air pump is used to inflate the valve mouth, so that the first airbag and the second airbag expand, and the cable is squeezed and fixed. Since the inner diameter of the hollow tube gradually increases from one end to the other, the contact between the second airbag and the cable can increase the folding angle of the cable, protecting the cable end while cooperating with the first airbag to further fix the cable to prevent it from falling out without causing damage to the cable. It is more practical and easy to operate.

[0017] 2. In the present invention, the traction hook pulls the whole to move. At this time, the number of the first mortar-shaped groove and the second mortar-shaped groove is several and they are arranged in a circular array. Balls are installed inside to roll. When the balls come into contact with the bridge frame, the friction can be reduced, which is more labor-saving and further improves the protection of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In this utility model:

[0026] Reference Figure 1-4 :

[0027] Embodiment 1: A cable end fixing device, wherein a connecting plate 101 is integrally provided inside a hollow tube 1, a clamping structure capable of clamping a cable is provided outside the hollow tube 1, and a protective structure capable of protecting a cable end is movably connected inside the hollow tube 1;

[0028] The clamping structure includes: a sleeve 2 and a first airbag 201; the sleeve 2 is fixedly installed on the outside of the hollow tube 1, and the first airbag 201 is embedded in the inner wall of the sleeve 2;

[0029] The protective structure includes: a traction head 3, a column 4, a second airbag 401, and a screw rod 402; the column 4 is movably connected to the inside of the hollow tube 1, the second airbag 401 is embedded in the outer wall of the column 4, and the screw rod 402 is fixedly installed at the tail of the column 4; the column 4 is inserted into the inside of the hollow tube 1, and since a connecting hole is provided on the surface of the connecting plate 101, the screw rod 402 passes through the connecting hole and is connected to the nut. This setting can fix the column 4 and the hollow tube 1.

[0030] The head of the plug post 4 is integrated with a traction head 3; the traction head 3 is integrated with a second mortar-shaped groove 301 around it, and the sleeve 2 is integrated with a first mortar-shaped groove 202 around it. The number of the first mortar-shaped groove 202 and the second mortar-shaped groove 301 are several, and they are arranged in a circular array. Balls are installed inside the first mortar-shaped groove 202 and the second mortar-shaped groove 301 are several, and they are arranged in a circular array. Balls are installed inside the first mortar-shaped groove 202 and the second mortar-shaped groove 301. When the balls come into contact with the bridge frame, the friction can be reduced, which saves more effort.

[0031] Furthermore, the inner diameter of the hollow tube 1 gradually increases from one end to the other. The contact between the second airbag 401 and the cable can increase the folding angle of the cable, protecting the cable end while cooperating with the first airbag 201 to further fix the cable to prevent it from falling out.

[0032] Furthermore, a connection hole is provided on the surface of the connection plate 101, and the screw rod 402 passes through the connection hole and is connected to the nut.

[0033] Furthermore, the traction head 3 is hemispherical, and a hook is integrated in the center. The hemispherical traction head 3 can avoid obstacles, and is more practical.

[0034] Furthermore, valves are nested on the sides of the sleeve 2 and the traction head 3, and the valves are connected to the first airbag 201 and the second airbag 401 through pipes. An air pump is used to inflate the valves to expand the first airbag 201 and the second airbag 401, thereby squeezing and fixing the cables and avoiding damage to the cables.

[0035] Reference Figure 4-5 , Example

[0036] In addition to the embodiment in which the traction head 3 is hemispherical, there is another embodiment in which the traction head 3 is conical. This design also has the function of avoiding obstacles and, at the same time, has a better ability to eliminate resistance.

[0037] Working principle: First, insert the cables side by side between the hollow tube 1 and the sleeve 2, adjust the inserted wire ends to be equal in length, about 12CM-16CM, then fold the wire ends back and insert the wire ends into the hollow tube 1. At this time, insert the plug 4 into the hollow tube 1. Since the surface of the connecting plate 101 is provided with a connecting hole, the screw 402 passes through the connecting hole and is connected to the nut. This setting can fix the plug 4 to the hollow tube 1. Then, since the sides of the sleeve 2 and the traction head 3 are nested with valves, and the valves are connected to the first airbag 201 and the second airbag 401 through a pipe, use an air pump to inflate the valve. The air in the hollow tube 1 is inflated to expand the first airbag 201 and the second airbag 401, and the cable is squeezed and fixed. Since the inner diameter of the hollow tube 1 gradually increases from one end to the other, the contact between the second airbag 401 and the cable can increase the folding angle of the cable, and protect the cable end while cooperating with the first airbag 201 to further fix the cable to prevent it from falling out. Finally, the staff pulls the hook to move the whole. At this time, the number of the first mortar-shaped groove 202 and the second mortar-shaped groove 301 is several, and they are arranged in a circular array. Balls are installed inside. When the balls come into contact with the bridge frame, etc., friction can be reduced, which is more labor-saving.
