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.

[0017] Example: Figures 1-4 As shown, this utility model provides a DC contactor contact fixing cavity, including a base plate 1, a fixing frame 2 integrally formed on the top of the base plate 1, and an adjustment door 3 hinged to one side of the fixing frame 2. A groove 11 is provided at the upper end of the base plate 1, and a DC contactor body 4 is detachably provided in the groove 11. A fixing mechanism 5 and an auxiliary mechanism 6 that cooperate with the DC contactor body 4 are respectively provided on the base plate 1 and the fixing frame 2. The fixing mechanism 5 includes a cylindrical body 51, which is fixedly installed on the base plate 1. The cylindrical body 51 has a symmetrical structure. The cylindrical body 51 has a cooperating inner groove 52, a connecting groove 53, a recessed groove 54, and a retaining groove 55. A rotating rod 56 is rotatably inserted into the inner groove 52 and the recessed groove 54. There are four retaining grooves 55 arranged in an array. A rotating plate 57 is fixedly sleeved on the bottom end of the rotating rod 56. One end of the rotating plate 57 can slide through the connecting groove 53 and connect with the DC contactor. The bottom end of the main body 4 slides and fits together. A rotating hole 512 is provided through between the inner groove 52 and the sinker 54, and the rotating rod 56 is rotatably inserted into the rotating hole 512. The rotating hole 512 ensures the stable rotation of the rotating rod 56. One end of the rotating plate 57 has a through-hole 513, and the bottom end of the rotating rod 56 is fixedly inserted into the through-hole 513. The through-hole 513 ensures the stable connection between the rotating rod 56 and the rotating plate 57. At the other end, a torsion spring 58 is fixedly installed, and the top end of the torsion spring 58 is fixedly connected to the inner wall of the inner groove 52. A sleeve 59 is slidably sleeved on the top end of the rotating rod 56, and a torsion spring 510 is fixedly installed at the bottom end of the sleeve 59. An array of anti-slip grooves 514 are provided on the upper end of the sleeve 59. The anti-slip grooves 514 can increase friction and facilitate operation. The end of the torsion spring 510 is fixedly connected to the inner wall of the recess 54. The top end of the rotating rod 56 is integrally formed. There are symmetrically distributed guide blocks 515, and the guide blocks 515 are slidably inserted into the inner wall of the sleeve 59. The inner wall of the sleeve 59 is provided with symmetrically arranged guide grooves 516, and the guide blocks 515 are slidably inserted into the guide grooves 516. The cooperation between the guide blocks 515 and the guide grooves 516 plays a limiting and guiding role in the movement adjustment of the sleeve 59. The lower end of the sleeve 59 is integrally formed with symmetrically arranged locking blocks 511, and the locking blocks 511 can be slidably inserted into the locking grooves 55.

[0018] By adopting the above technical solution, when using it, open the adjustment door 3, then hold the two sleeves 59 in sequence and move them upwards, so as to stretch the corresponding torsion spring 510 and completely separate the corresponding locking block 511 from the corresponding locking groove 55. Then rotate the corresponding sleeve 59, so as to drive the rotating rod 56 and the rotating plate 57 to rotate and twist the corresponding torsion spring 58 and the torsion spring 510. When the sleeve 59 rotates 90 degrees, it moves downwards, so that the corresponding locking block 511 can be inserted into the other corresponding locking groove 55. Then hold the DC contactor body 4 and insert its end into the groove 11. Then, reverse the above steps to reset the rotating plate 57.

[0019] The auxiliary mechanism 6 includes a slide rod 61, which is slidably inserted into the top of the fixed frame 2, and a pressure plate 62 is fixedly sleeved at the bottom of the slide rod 61. A symmetrically arranged sliding hole 21 is opened through the top of the fixed frame 2, and the slide rod 61 is slidably inserted into the sliding hole 21. The sliding hole 21 is used to limit and guide the movement of the slide rod 61. The end of the pressure plate 62 near the regulating door 3 is arc-shaped, and a spring 63 is fixedly installed at the end of the pressure plate 62 away from the regulating door 3. The top of the spring 63 is fixedly connected to the inner wall of the fixed frame 2.

[0020] By adopting the above technical solution, when in use, hold the DC contactor body 4 in the back hand and push it into the fixed frame 2. At this time, the DC contactor body 4 will contact the arc-shaped parts of the two pressure plates 62 and push the corresponding pressure plates 62 to move, thereby driving the corresponding slide rod 61 to move and squeeze the spring 63 until the end of the DC contactor body 4 is stuck into the groove 11.

[0021] Working principle: When in use, open the adjustment door 3, then hold the two sleeves 59 in turn and move them upwards, so as to stretch the corresponding torsion spring 510 and completely separate the corresponding locking block 511 from the corresponding locking groove 55. Then rotate the corresponding sleeve 59, so as to drive the rotating rod 56 and the rotating plate 57 to rotate and twist the corresponding torsion spring 58 and the torsion spring 510. When the sleeve 59 rotates 90 degrees, it moves downwards, so that the corresponding locking block 511 can be inserted into the other corresponding locking groove 55. Then, hold the DC contactor body 4 and push it into the fixed frame 2. At this time, the DC contactor body 4 will contact the arc-shaped parts of the two pressure plates 62 and push the corresponding pressure plates 62 to move, thereby driving the corresponding slide rod 61 to move and squeeze the spring 63 until the end of the DC contactor body 4 is stuck into the groove 11. Then, reverse the above steps to reset the rotating plate 57.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
