Description

Technical Field

[0001] This utility model relates to the field of wire and cable testing technology, and in particular to a test clip that is easy to fix. Background Technology

[0002] Wires and cables are conductor materials used for power transmission and signal transmission. They play an important role in modern life and are widely used in fields such as construction, power systems, and communication systems. Wires usually refer to a single conductor and are mainly used for power transmission and electrical connection, while cables are usually composed of multiple conductors and insulation layers and are mainly used for power, signal and control.

[0003] The prior art (publication number: CN218157247U) discloses a wire and cable testing fixture, including a testing platform. Two sets of first sliding grooves are provided on the upper outer surface of the testing platform. A fixture assembly is provided on the upper outer surface of the first sliding groove. A replacement component is provided on one side of the upper outer surface of the fixture assembly. The fixture assembly includes an upper clamp, a first connecting block, a threaded rod, a lower clamp, an anti-slip pad, a wire placement groove, a self-locking rod, a second sliding groove, a second connecting block, a guide rod, a housing, and a cylinder. The housing is provided on the upper outer surface of the first sliding groove. The wire and cable testing fixture of this invention, through its fixture assembly, allows the tester to easily adjust the curvature of the wire placement groove according to the thickness of the wire and cable. The replacement component allows the tester to easily replace the clamping block in the lower arc-shaped groove of the upper clamp, thereby adjusting the curvature of the corresponding wire placement groove.

[0004] After securing both ends of the wire, the clamp needs to be manually pulled to the opposite side, which is quite troublesome. Furthermore, when testing other positions of the wire, the clamp must first be released from its hold, and then the wire must be lifted while its position is adjusted, which is also quite cumbersome.

[0005] Therefore, those skilled in the art have provided a test clip that is easy to fix in order to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a test clip that is easy to fix. By setting an adjustment mechanism to drive the fixing mechanism to move, the fixing mechanism does not need to be pulled manually, which is more convenient. By setting two rotatable compression cylinders to fix the surface of the wire, it is easy to change the pulling position of the wire.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a test clip that is easy to fix, comprising an adjustment mechanism and four fixing mechanisms. The adjustment mechanism includes a base, two bidirectional lead screws, a U-shaped plate, two pulleys, a sliding groove, a dual-axis motor, two unidirectional lead screws, two first sliding plates, four second sliding plates, and four first pressing blocks. A single-axis motor is fixedly installed on one side of the rear end face of the base. The U-shaped plate is fixedly installed on the front end of the base by bolts. A belt is provided between the two pulleys. A controller is fixedly installed on the rear side of one end face of the base. Second pressing blocks are fixedly installed on the lower side of the opposite end faces of the four second sliding plates.

[0008] The four fixing mechanisms include four sliders, four electric telescopic rods, and four lifting plates. Limiting blocks are fixedly installed on both sides of the upper end face of the four sliders. Support plates are fixedly installed on the upper side of the opposite end faces of the multiple limiting blocks. Extrusion cylinders are rotatably installed between the opposite end faces of the multiple limiting blocks and the inner walls of the opposite sides of the four lifting plates. Anti-slip pads are fixedly sleeved on the outer end faces of the four extrusion cylinders. Pointers are fixedly installed at the lower ends of four of the multiple limiting blocks.

[0009] Furthermore, the two bidirectional lead screws are respectively rotatably disposed on both sides of the front end face of the base, and the two pulleys are respectively rotatably disposed on both sides of the front end face of the U-shaped plate, with the rear ends of the two pulleys being slidably connected to the front ends of the two bidirectional lead screws respectively.

[0010] Furthermore, the sliding groove is located in the middle of the upper surface of the base, the dual-axis motor is fixedly installed in the middle of the bottom surface of the sliding groove, and the two unidirectional lead screws are respectively fixedly connected to the two ends of the dual-axis motor.

[0011] Furthermore, the inner walls of the two first slide plates are respectively threaded onto opposite sides of the outer end faces of the two one-way screws, and the four second slide plates are slidably connected to the two first slide plates in pairs.

[0012] Furthermore, one end of each of the four first extrusion blocks is slidably connected to one of the four second sliding plates, and the other end of each of the four first extrusion blocks is slidably connected to one of the four support plates.

[0013] Furthermore, one rear end of one side of the two bidirectional lead screws is fixedly connected to the output end of the single-axis motor, and the four sliders are respectively threaded onto the front and rear sides of the outer ends of the two bidirectional lead screws.

[0014] Furthermore, the four electric telescopic rods are respectively embedded in the middle of the upper surface of the four support plates, and the four lifting plates are respectively fixedly connected to the output ends of the four electric telescopic rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a test clip that is easy to fix. After manually placing the wire between two fixing mechanisms and fixing both ends of the wire, the single-axis motor is turned on to drive the bidirectional lead screw to rotate, which can move the two fixing mechanisms on its surface to opposite sides. It is more convenient because it does not require manual pulling of the two ends of the wire. In addition, according to the needs, the rear end of the pulley can be selected to be inside the bidirectional lead screw to pull a single wire or two wires, reducing the cost of use.

[0017] 2. The test clamp proposed in this utility model is easy to fix. The lifting plate is moved by an electric telescopic rod, which can fix wires of different diameters, improving the practicality of the device. It is more convenient because it does not require manual fixing. After the wire is pulled at one position, the dual-axis motor can be turned on to drive the two first sliding plates to move towards the middle, so that the sharp blocks on the surface of the first and second extrusion blocks do not abut against the rotating shaft end of the extrusion cylinder. At this time, the wire can be pulled directly, which can make it easier to pull the wire at other positions. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a test clip that is easy to fix, including an adjustment mechanism 1 and four fixing mechanisms 2. The adjustment mechanism 1 includes a base 101, two bidirectional lead screws 102, a U-shaped plate 104, two pulleys 105, a sliding groove 107, a dual-axis motor 108, two unidirectional lead screws 109, two first sliding plates 111, four second sliding plates 112, and four first pressing blocks 113. The U-shaped plate 104 is fixedly mounted on the front end of the base 101 by bolts. A belt 106 is arranged between the two pulleys 105. A controller 110 is fixedly installed on the rear side of one end face of the base 101. Two bidirectional lead screws 102 are respectively rotatably installed on both sides of the front end face of the base 101. Two pulleys 105 are respectively rotatably installed on both sides of the front end face of the U-shaped plate 104. The rear ends of the two pulleys 105 are slidably connected to the front ends of the two bidirectional lead screws 102. One rear end of one side of the two bidirectional lead screws 102 is fixedly connected to the output end of the single-axis motor 103. Four sliders 201 are threadedly sleeved on the front and rear sides of the outer end faces of the two bidirectional lead screws 102.

[0028] Specifically, the wire is placed between two fixing mechanisms 2, and one end of the wire is fixed by the fixing mechanism 2. After both ends of the wire are fixed, the single-axis motor 103 is turned on to drive a bidirectional lead screw 102 to rotate. During the rotation, the two sliders 201 on its surface move to opposite sides, thereby pulling the two ends of the wire to test the wire's toughness. During the test, it is possible to choose to test one wire or two wires. When testing only one wire, the bolt at the front end of the base 101 is manually turned to release the fixing of the U-shaped plate 104. At this time, the U-shaped plate 104 can be pulled to drive the rear ends of the two pulleys 105 away from the inside of the two bidirectional lead screws 102, so that one wire can be pulled.

[0029] Reference Figure 2 and Figure 4The inner walls of the two first slide plates 111 are threaded onto the opposite sides of the outer end faces of the two one-way screws 109. The four second slide plates 112 are slidably connected to the two first slide plates 111 in pairs. One end of the four first extrusion blocks 113 is slidably connected to the four second slide plates 112, and the other end of the four first extrusion blocks 113 is slidably connected to the four support plates 203.

[0030] Specifically, when the slider 201 moves, the pointed blocks on the surfaces of the first extrusion block 113 and the second extrusion block 114 abut against the rotating shaft end of the extrusion cylinder 206, and because the first extrusion block 113 is located inside the support plate 203, the second slide plate 112 can be driven to slide inside the first slide plate 111. This prevents the two extrusion cylinders 206 inside the fixing mechanism 2 from rotating when the slider 201 moves, thus ensuring the stability of the wire fixation.

[0031] Reference Figure 5 and Figure 6 The four fixed mechanisms 2 include four sliders 201, four electric telescopic rods 204, and four lifting plates 205. Limiting blocks 202 are fixedly installed on both sides of the upper end face of the four sliders 201. Support plates 203 are fixedly installed on the upper side of the opposite end face of each pair of limiting blocks 202. Extrusion cylinders 206 are rotatably installed between the opposite end face of each pair of limiting blocks 202 and between the opposite inner wall of the four lifting plates 205. Anti-slip pads 207 are fixedly sleeved on the outer end face of each of the four extrusion cylinders 206. Pointers 208 are fixedly installed at the lower end of each of the four limiting blocks 202. A sliding groove 107 is opened in the middle of the upper end face of the base 101. A dual-axis motor 108 is fixedly installed in the middle of the bottom surface of the sliding groove 107. Two one-way lead screws 109 are fixedly connected to the two ends of the dual-axis motor 108 respectively. The four electric telescopic rods 204 are embedded in the middle of the upper end face of the four support plates 203 respectively. The four lifting plates 205 are fixedly connected to the output ends of the four electric telescopic rods 204 respectively.

[0032] Specifically, by moving the lifting plate 205 upwards via the electric telescopic rod 204, the distance between the two extrusion cylinders 206 inside the fixing mechanism 2 can be changed, thereby allowing for the fixing of wires of different diameters and improving the practicality of the device. After the toughness test of one part of the wire is completed, other parts of the wire can be tested. At this time, the dual-axis motor 108 is turned on by the controller 110 to drive the two one-way lead screws 109 to rotate, thereby driving the two first slide plates 111 to move closer to the center. During the movement of the first slider 201, it drives the two second slide plates 112 inside the first slide plate 111 to move together, thereby causing the first extrusion block 113 to slide inside the lifting plate 205. At this time, the sharp blocks on the surface of the first extrusion block 113 and the second extrusion block 114 do not abut against the rotating shaft of the two extrusion cylinders 206 inside the fixing mechanism 2. Then the wire is pulled. During the pulling process, the two extrusion cylinders 206 inside the fixing mechanism 2 rotate without obstructing the wire.

[0033] Working principle: The dual-axis motor 108 is turned on by the controller 110, causing the two first slide plates 111 to move closer together. At this time, the four electric telescopic rods 204 are turned on, driving the four lifting plates 205 to move upward. Then, the two wires are inserted from the two fixing mechanisms 2 in the same row. After they are in place, the wires are pulled. When they are pulled to the appropriate position, the four electric telescopic rods 204 are turned on, driving the four lifting plates 205 to move downward. This causes the two extrusion cylinders 206 inside one of the fixing mechanisms 2 to fix the wires. Then, the dual-axis motor 108 drives the two first slide plates 111 back to their original positions. Finally, the single-axis motor 103 is turned on, driving the two bidirectional lead screws 102 to pull, thus pulling the wires.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
