[0030] Please refer to Figures 1-6 As shown, the present utility model is a splicing fitting with an adjustable clamping structure, including a housing 1. A clamping assembly 2 is arranged inside the housing 1. A driving assembly 3 is rotatably connected inside the housing 1. The outer surface of the driving assembly 3 is drivingly connected with a rotating assembly 4. The outer surface of the rotating assembly 4 is provided with a supporting assembly 5. The supporting assembly 5 is fixedly connected inside the housing 1. The clamping assembly 2 is used to fix the wire. The driving assembly 3 is used to drive the rotating assembly 4 to rotate. The rotating assembly 4 is used to twist the wire.

[0031] Insert two wires into the housing 1 so that the wires are inside the clamping assembly 2 and the rotating assembly 4 inside the housing 1. Close the clamping assembly 2 to connect and fix the two wires. At this time, drive the rotating assembly 4 to rotate through the driving assembly 3. The supporting assembly 5 supports the rotation of the rotating assembly 4. The rotating assembly 4 can twist the two wires so that they are wound together. By changing the distance between the clamping assemblies 2 and the number of turns of the rotating assembly 4 rotating, the tightness of the connection of the two wires can be adjusted.

[0032] In the present utility model, through the connection of the driving assembly 3 and the rotating assembly 4, the driving assembly 3 is drivingly connected with the rotating assembly 4. The driving assembly 3 can drive the rotating assembly 4 to rotate so that the two wires are twisted and wound together. By changing the distance between the clamping assemblies 2 and the number of turns of the rotating assembly 4 rotating, the tightness of the connection of the two wires can be adjusted. The driving assembly 3 extends to the outside of the housing 1, which is convenient for the staff to operate the driving assembly 3 to drive the rotating assembly 4, thereby completing the adjustment of the tightness of the wire.

[0033] In one embodiment, for the above clamping assembly 2, the clamping assembly 2 includes a screw rod 201. The outer surface of the screw rod 201 is threadedly connected with a first clamping block 202 and a second clamping block 203. The outer surfaces of the first clamping block 202 and the second clamping block 203 are both slidably connected with a round rod 204. The round rod 204 is fixedly connected inside the housing 1. The screw rod 201 is rotatably connected with the housing 1. One end of the screw rod 201 extends to the outside of the housing 1.

[0034] There are two groups of the screw rod 201, the first clamping block 202, the second clamping block 203 and the round rod 204.

[0035] Insert two wires into the inside of the housing 1 from both sides respectively. The two wires are located between the first clamping block 202 and the second clamping block 203, and the two wires are close to each other. Rotate the screw 201 to drive the first clamping block 202 and the second clamping block 203. The rotation tendency of the first clamping block 202 and the second clamping block 203 is blocked by the round rod 204 to avoid unnecessary rotation of the first clamping block 202 and the second clamping block 203. At this time, the first clamping block 202 and the second clamping block 203 can move along the round rod 204. When the first clamping block 202 and the second clamping block 203 approach each other, they can clamp the two wires and fix them.

[0036] In one embodiment, for the above-mentioned driving assembly 3, the driving assembly 3 includes a rotating rod 301. A gear 302 is fixedly connected to the outer surface of the rotating rod 301. The rotating rod 301 is rotatably connected to the inside of the housing 1, and one end of the rotating rod 301 extends to the outside of the housing 1.

[0037] In one embodiment, for the above-mentioned rotating assembly 4, the rotating assembly 4 includes a toothed ring 401. A circular ring 402 is fixedly connected to the outer surface of the toothed ring 401. The outer surface of the circular ring 402 is rotatably connected to a ring cover 403. The toothed ring 401 meshes with the gear 302, and a fixing rod 404 is fixedly connected to the outer surface of the toothed ring 401.

[0038] Rotate the rotating rod 301. The rotating rod 301 drives the gear 302 to rotate. The gear 302 meshes with the toothed ring 401 and drives the toothed ring 401 to rotate. The circular ring 402 on the toothed ring 401 rotates in the ring cover 403. Since the two wires are respectively located on both sides of the fixing rod 404 inside the toothed ring 401, when the toothed ring 401 drives the fixing rod 404 to rotate, the fixing rod 404 can twist and wind the two wires together.

[0039] In one embodiment, for the above-mentioned supporting assembly 5, the supporting assembly 5 includes a vertical plate 501. The vertical plate 501 is fixedly connected to the housing 1. The vertical plate 501 is fixedly connected to the ring cover 403. A through hole 502 is formed in the outer surface of the vertical plate 501 for passing a wire through.

[0040] The vertical plate 501 supports the ring cover 403 and the circular ring 402 to maintain the normal rotation of the toothed ring 401 and the circular ring 402 and prevent the circular ring 402 from falling off. The through hole 502 in the vertical plate 501 enables the wire to pass through the vertical plate 501, and at the same time can also support and limit the wire.

[0041] In one embodiment, for the above-mentioned housing 1, an ear plate 6 is fixedly connected to the outer surface of the housing 1. The ear plate 6 is used for passing a bolt through to fix the housing 1.

[0042] There are multiple groups of ear plates 6, and screw holes are provided on the ear plates 6. Bolts can be inserted into the screw holes on the ear plates 6 to fix them to the connection brackets.

[0043] In one embodiment, for the above-mentioned screw rod 201, handwheels 7 are fixedly connected to the ends of the screw rod 201 and the rotating rod 301, and the handwheels 7 are located outside the housing 1.

[0044] The outer surface of the handwheel 7 is coated with a rubber layer. The rubber layer can protect the handwheel 7 and increase the friction force at the same time, facilitating the staff to rotate the handwheel 7.

[0045] In summary, by means of the above technical solution of the present utility model, two wires are respectively inserted into the housing 1 from both sides of the housing 1. The wires pass through the first clamping block 202, the second clamping block 203, the through hole 502 and the toothed ring 401 inside the housing 1, and the two wires are respectively located on both sides of the fixing rod 404 inside the toothed ring 401. Rotate the screw rod 201 above the housing 1. The screw rod 201 drives the first clamping block 202 and the second clamping block 203. The rotation tendency of the first clamping block 202 and the second clamping block 203 is blocked by the round rod 204, avoiding unnecessary rotation of the first clamping block 202 and the second clamping block 203. At this time, the first clamping block 202 and the second clamping block 203 can move along the round rod 204. When the first clamping block 202 and the second clamping block 203 approach each other, they can clamp the two wires and fix them. Then rotate the rotating rod 301 on the side of the housing 1. The rotating rod 301 drives the gear 302 to rotate. The gear 302 meshes with the toothed ring 401 and drives the toothed ring 401 to rotate. The circular ring 402 on the toothed ring 401 rotates in the ring cover 403. The vertical plate 501 can support the ring cover 403. Since the two wires are respectively located on both sides of the fixing rod 404 inside the toothed ring 401, when the toothed ring 401 drives the fixing rod 404 to rotate, the fixing rod 404 can twist and wind the two wires together. By adjusting the distance between the first clamping block 202 and the second clamping block 203 and the number of turns of the fixing rod 404 rotating, the tightness of the connection between the two wires can be adjusted.

[0046] Through the above technical solutions: 1. By connecting the driving component 3 and the rotating component 4, the driving component 3 is in transmission connection with the rotating component 4. The driving component 3 can drive the rotating component 4 to rotate so that the two wires are twisted and wound together. By changing the distance between the clamping components 2 and the number of turns of the rotating component 4, the tightness of the connection between the two wires can be adjusted. The driving component 3 extends to the outside of the housing 1, which is convenient for the staff to operate the driving component 3 to drive the rotating component 4, thus completing the adjustment of the tightness of the wire; 2. By connecting the gear 302 and the toothed ring 401, rotate the rotating rod 301. The rotating rod 301 drives the gear 302 to rotate. The gear 302 meshes with the toothed ring 401 and drives the toothed ring 401 to rotate. The fixing rod 404 in the toothed ring 401 can twist and wind the two wires together. By changing the distance between the first clamping block 202 and the second clamping block 203 and the number of turns of the fixing rod 404, the tightness of the connection between the two wires can be adjusted. The rotating rod 301 and the screw rod 201 both extend to the outside of the housing 1, which is convenient for the staff to rotate them to adjust the tightness of the wire.
