[0024] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.

[0025] The utility model discloses a kind of strain clamp suitable for transmission and transformation project.

[0026] The utility model provides a kind of strain clamp suitable for transmission and transformation project as Figures 1-3 As shown in the figure, the strain clamp suitable for transmission and transformation project includes first clamp 1 and the second clamp 2 that is connected with first clamp 1, the outside of second clamp 2 is equipped with multiple U-shaped pressing rods 3, the lower end of U-shaped pressing rod 3 is fixedly provided with connecting rod 4, connecting rod 4 is U-shapedly arranged, rubber pressing block 5 is fixedly sleeved on the rod wall upper end of U-shaped pressing rod 3, rubber pressing block 5 extends into second clamp 2, the both ends of the rod wall of U-shaped pressing rod 3 are slidably sleeved with limiting ring 8, limiting ring 8 is fixedly arranged on the outer wall of second clamp 2, the lower end of connecting rod 4 is fixedly sleeved with moving block 6, moving block 6 is in contact with push block 7, the side of moving block 6 and push block 7 being in contact is all arranged as inclined plane, the side of push block 7 away from moving block 6 is in contact with the outer wall of second clamp 2.

[0027] When using the strain clamp, first, the conductor is inserted into first clamp 1 and second clamp 2, at this time, since the lower end of U-shaped pressing rod 3 is connected with moving block 6 through connecting rod 4, moving block 6 is in contact with push block 7 and the contact surface is inclined plane, limiting ring 8 at both ends of the rod wall of U-shaped pressing rod 3 can limit the moving range of U-shaped pressing rod 3, to prevent it from shaking randomly, so that when push block 7 moves, according to the principle of inclined plane, moving block 6 will move downward under the push of push block 7, and then drive U-shaped pressing rod 3 to move downward, so that rubber pressing block 5 at the upper end of U-shaped pressing rod 3 generates downward pressure on the conductor, to play the role of preliminarily fixing the conductor.

[0028] In order to be able to drive multiple push blocks 7 simultaneously to make multiple moving blocks 6 move simultaneously and drive U-shaped pressing rod 3 to press and fix the conductor, as Figures 2-4 As shown in the figure, multiple push blocks 7 are commonly provided with a pushing and pressing mechanism, the pushing and pressing mechanism is used to drive multiple push blocks 7 to move, the pushing and pressing mechanism includes mounting plate 9, mounting plate 9 is fixedly arranged on the bottom of second clamp 2, and drive screw 10 is rotatably arranged in the inside of mounting plate 9, the rod wall of drive screw 10 is threadedly arranged in the inside of push block 7, and the end of drive screw 10 is fixedly provided with rotating plate 11.

[0029] When the push block 7 needs to be driven laterally, the rotating plate 11 is rotated, and the rotating plate 11 drives the driving screw 10 to rotate, since the driving screw 10 is threadedly connected with the push block 7, the rotation of the driving screw 10 will drive the push block 7 to move along the axial direction of the driving screw 10, and since the plurality of push blocks 7 are synchronously moved in this way, the plurality of push blocks 7 will simultaneously push the corresponding moving blocks 6, thereby driving the plurality of U-shaped pressing rods 3 to synchronously move downward, and the plurality of rubber pressing blocks 5 simultaneously apply greater pressure on the wires, so as to tightly press and fix the wires, and ensure the stable connection of the wires in the strain clamp.

[0030] In order to fix the position of the driving screw 10 after the push block 7 is driven, as shown in Figures 3-4 The inside of the rotating plate 11 is slidably provided with a positioning rod 12, the positioning rod 12 is a U-shaped positioning rod, the two side walls of the positioning rod 12 are both sleeved with a spring 13, the two ends of the spring 13 are fixedly connected with the positioning rod 12 and the rotating plate 11 respectively, and the outer wall of the mounting plate 9 is provided with a plurality of positioning grooves 14 which are arranged at intervals and surround the driving screw 10, and the end of the positioning rod 12 is inserted into the positioning groove 14 through the rotating plate 11.

[0031] Before the driving screw 10 is rotated, the positioning rod 12 can be pulled away from the mounting plate 9, so that the end of the positioning rod 12 is separated from the current positioning groove 14, and then the rotating plate 11 is rotated to adjust the position of the driving screw 10, when the push block 7 completes the pushing work of the moving block 6, the positioning rod 12 is loosened, and under the elastic force of the spring 13, the end of the positioning rod 12 is inserted into the corresponding positioning groove 14, thereby limiting the rotation of the driving screw 10, ensuring the position of the push block 7 is fixed, and maintaining the state of the wires being pressed.

Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the scope of protection of the present application.
