Description

Technical Field

[0001] This utility model belongs to the field of cable testing technology, and in particular relates to a multifunctional cable quick positioning clamp for a cable tester. Background Technology

[0002] The multi-functional cable quick positioning fixture for cable testers is a special tool used to assist cable testers in conducting tests. Its main function is to enable rapid positioning, fixing, and test preparation of cables, thereby improving testing efficiency and accuracy.

[0003] For example, Chinese patent CN214292752U discloses a positioning clamp for cable testing, including clamps, a base plate, and a slide plate disposed at one end of the base plate. The clamps are located between two sliders, forming a straight groove between the clamps for the cable to pass through. The base plate also has a cam assembly, which is arranged in a straight line and adjacent to an axial slot parallel to the straight groove. The height of the cam assembly is lower than the height of the slide plate. By connecting the clamps and sliders to the slide plate, the distance between the clamps can be controlled by rotating a screw, and the distance between the clamp's locking parts can be adjusted to match the cable thickness, allowing the clamps to adapt to the cable's thickness specifications and firmly fix the cable. The cam assembly, arranged in a straight line and adjacent to an axial slot parallel to the straight groove, is used to further distinguish and fix multiple cables or multiple branch cables from a main cable for separate testing.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as the fact that the cable testing positioning fixture is driven by two motors and two threaded rods, resulting in high manufacturing costs and an inability to quickly position cables. Therefore, we propose a multifunctional cable rapid positioning fixture for cable testers. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional cable quick positioning clamp for a cable tester, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a multifunctional cable quick positioning clamp for a cable tester, comprising:

[0008] The base and multiple rotating slots are formed on the inner wall of the base, and multiple clamping rods are rotatably connected in the multiple rotating slots;

[0009] Multiple first rotating slots are formed in the base and are respectively connected to multiple clamping rods. Multiple first gears are rotatably connected in the multiple first rotating slots, and one end of each of the multiple first gears extends into the multiple rotating slots and is fixed to the multiple clamping rods respectively.

[0010] The second rotating groove is formed inside the base and communicates with multiple first rotating grooves. A toothed ring is rotatably connected inside the second rotating groove, and the toothed ring meshes with multiple first gears.

[0011] A drive assembly, located within the base, is used to drive the gear ring to rotate.

[0012] Based on the above structure, the set rotating groove and clamping rod ensure that the clamping rod can rotate within the rotating groove. The set first rotating groove and first gear ensure that the first gear can rotate within the first rotating groove, allowing the first gear to drive the clamping rod to rotate within the rotating groove. The set second rotating groove and gear ring ensure that the gear ring can rotate within the second rotating groove, allowing the gear ring to drive multiple first gears to rotate. The set driving component ensures that the user can drive the gear ring to rotate within the second rotating groove through the driving component.

[0013] In the above technical solution, the driving component further includes:

[0014] The third rotating groove is formed on the inner wall of the second rotating groove. A second gear is rotatably connected in the third rotating groove. A fourth rotating groove is formed on the inner wall of the third rotating groove. A third gear is rotatably connected in the fourth rotating groove. The third gear meshes with the second gear. A first rotating rod is fixedly connected to the third gear. One end of the first rotating rod passes through the inner wall of the fourth rotating groove and extends to the outside to be rotatably connected to the base.

[0015] A fixing component is located on the first rotating rod and is used to fix the first rotating rod.

[0016] In this technical solution, it is ensured that when multiple clamping rods are rotated to the appropriate position, the multiple clamping rods can quickly clamp and fix the cable.

[0017] In the above technical solution, the fixing component further includes:

[0018] A chute is formed inside a first rotating rod and connected to the outside. A slider is slidably connected inside the chute, and both ends of the slider extend to the outside. The two ends of the slider are fixedly connected to the same extrusion block, which is located on the periphery of the first rotating rod and slidably connected to the periphery of the first rotating rod. A threaded rod is threadedly connected inside the slider. One end of the threaded rod is fixedly connected to a second rotating rod, and one end of the second rotating rod penetrates the inner wall of the chute and extends to the outside, where it is rotatably connected to the first rotating rod.

[0019] In this technical solution, it is ensured that the first rotating rod can be fixed.

[0020] In the above technical solution, furthermore, one end of the second rotating rod is fixedly connected to an anti-slip block.

[0021] In this technical solution, it is ensured that the user can rotate the second rotating rod by using the anti-slip block at one end of the second rotating rod, and it is also ensured that the user's hand will not slip when rotating the second rotating rod.

[0022] In the above technical solution, furthermore, the two ends of the slider are slidably connected to the first rotating rod.

[0023] In this technical solution, it is ensured that when the slider slides, both ends of the slider can slide normally within the first rotating rod.

[0024] In the above technical solution, the number of teeth of the third gear is greater than the number of teeth of the second gear.

[0025] In this technical solution, it is ensured that when the third gear rotates, the third gear will quickly drive the second gear to rotate.

[0026] In the above technical solution, one end of the first gear is rotatably connected to the rotating groove.

[0027] In this technical solution, it is ensured that when the first gear rotates, one end of the first gear can rotate normally within the rotating groove.

[0028] The beneficial effects of this utility model are:

[0029] 1. This cable tester uses a multi-functional cable quick positioning fixture. Through a rotating groove and a clamping rod, the clamping rod can rotate within the rotating groove. Through a first rotating groove and a first gear, the first gear can rotate within the first rotating groove, driving the clamping rod to rotate within the rotating groove. Through a second rotating groove and a gear ring, the gear ring can rotate within the second rotating groove, driving multiple first gears to rotate. Through a driving component, the user can drive the gear ring to rotate within the second rotating groove. This solves the problems of high manufacturing cost and inability to quickly position cables using positioning fixtures for cable testing.

[0030] 2. This cable tester uses a multi-functional cable quick positioning fixture. Through the setting of a first rotating rod, a slide groove, a slider, and a pressing block, it ensures that the pressing block can slide along the slide groove on the circumference of the first rotating rod. Through the setting of a threaded rod and a second rotating rod, it ensures that when the user rotates the second rotating rod, the second rotating rod can drive the threaded rod to rotate in the slide groove, so that the slider is subjected to the action of the threaded rod and moves along the slide groove, allowing the slider to drive the pressing block to move. When the pressing block moves to the appropriate position, the pressing block can fix the first rotating rod on the base and prevent it from rotating. Attached Figure Description
