Technical Field

[0001] This utility model belongs to the field of cable testing technology, specifically relating to a testing fixture for cable intermediate joints. Background Technology

[0002] Currently, testing cable joints involves manually installing and fixing the test cable to the joint before conducting the required tests. After testing, the joint must be manually removed from the test cable, which is time-consuming and labor-intensive.

[0003] Existing cable joint testing fixtures have the following drawbacks: the drive mechanism is complex and cannot be adjusted simultaneously, causing inconvenience in use; the joint fixing mechanism is not secure, affecting testing; and the height of the fixing ring cannot be adjusted, causing the cable and joint to be out of sync, thus affecting the test results.

[0004] In view of this, a test fixture for cable intermediate joints is designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a cable intermediate joint testing fixture, which features convenient drive adjustment, reliable joint fixation, and adjustable fixing ring height.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a test fixture for cable intermediate joints, comprising a frame, drive components on both sides of the upper end of the frame, a placement plate in the middle of the upper end of the frame, joint fixing components on both sides of the placement plate, a fixing platform mounted on the upper end of the drive components, and adjustable fixing rings mounted on both sides of the fixing platform. The drive assembly includes a bidirectional lead screw, which is rotatably connected to the middle of the frame. The two sides of the bidirectional lead screw are screwed together. There are movable seats on both sides of the upper end of the frame. The top of the movable seats is threaded and fixed to the fixed platform. Slide seats are provided around the bottom of the fixed platform. Slide rails are installed on both sides of the upper end of the frame. The slide seats are connected to the slide rails. A bevel gear one is installed in the middle of the bidirectional lead screw. A rotating rod is installed in the middle of the side of the frame. A bevel gear two is fixed to one end of the rotating rod near the bevel gear one. The other end of the rotating rod is connected to a turntable.

[0007] Preferably, the two ends of the bevel gear are fixed to the frame by bearing seats, and the bidirectional lead screw is rotatably connected to the bearing seats.

[0008] Preferably, the first bevel gear and the second bevel gear are meshed together, and the rotating rod is rotatably connected to the frame.

[0009] Preferably, the joint fixing assembly includes a mounting base plate, with fixing posts fixedly connected to both sides of the upper end of the mounting base plate, a lower plate body slidably inserted into the middle groove of the fixing posts, an upper plate body provided above the lower plate body, fixing holes opened at the upper ends of both sides of the upper plate body, limit grooves provided on the sides of the fixing posts, and fasteners screwed into the middle of the fixing holes.

[0010] Preferably, the fastener includes a bolt, an adjusting disc is connected to the side of the bolt, and a pressure plate is rotatably connected to the end of the bolt surface near the adjusting disc.

[0011] Preferably, a bolt is screwed into the middle of the fixing hole, and the surface of the pressure plate is in close contact with the side wall of the placement plate.
