DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, the utility model provides a sensor fixing device for a circuit breaker, comprising a fixing frame 1, a clamping mechanism 2 is arranged inside the fixing frame 1, a stabilizing mechanism 3 is installed at one end of the clamping mechanism 2, and limiting mechanisms 4 are installed on the surfaces of both sides of the fixing frame 1;

[0022] The clamping mechanism 2 includes a moving block 21 , two sliders 22 fixedly connected to both sides of the moving block 21 , two power plates 23 slidably connected to the two sliders 22 , and two clamping blocks 24 assembled at one end of the two power plates 23 .

[0023] The above scheme is adopted: as the main frame of the entire device, it provides space for installation and operation of other mechanisms, its internal space is used to accommodate the clamping mechanism 2, etc., and the surfaces on both sides are used to assemble the limiting mechanism 4 to ensure the integrity and stability of the entire device structure. Through the setting of the clamping mechanism 2, the sliders 22 on both sides of the moving block 21 are slidably connected with the power plate 23, and the clamping block 24 at one end of the power plate 23 can be flexibly moved and adjusted according to the size of the sensor, so as to adapt to sensors of different sizes and achieve wide applicability. The reset spring 31, reset telescopic column 32 and other components in the stabilizing mechanism 3 can ensure the smoothness and reliability of the clamping process, and the cooperation between the auxiliary block 33 and the telescopic rod 34 further enhances the stability.

[0024] like Figures 1 to 4 As shown, a mounting plate 101 is installed on the bottom surface of the fixed frame 1, and fixing plates are fixedly connected on both sides of the mounting plate 101. There are two fixing plates, and mounting holes are provided inside the two fixing plates. Slide grooves are provided on both sides of the fixed frame 1, and the slide grooves are adapted to the power plates 23. Power grooves adapted to the two sliders 22 are provided on the opposite sides of the two power plates 23. One end of the two power plates 23 is fixedly connected with a protruding block 231, and one end of the fixed frame 1 is provided with a groove adapted to the protruding block 231. Fixing bolts are fixedly installed on the surfaces of the two clamping blocks 24, and the fixing bolts are located on the same straight line.

[0025] The above scheme is adopted: the moving block 21 is the trigger component of the clamping action. By pushing the moving block 21, the movement of the subsequent components is driven to realize the clamping function. The sliders 22 are fixed on both sides of the moving block 21 and cooperate with the power grooves on the power plate 23 to play a role of precise guidance and power transmission, ensuring that the movement of the moving block 21 can be accurately converted into the movement of the power plate 23. The power plate 23 moves along the slide groove under the action of the slider 22, thereby driving the clamping block 24 to perform the clamping operation. The raised block 231 on the power plate 23 cooperates with the groove on the fixed frame 1 to further ensure the stability and accuracy of the movement of the power plate 23. The clamping block 24 directly contacts the sensor and applies the clamping The tightening force is used to fix the sensor. The fixing bolts on the surface can be used to connect with other components to enhance the reliability of fixation. The reset spring 31 is sleeved on the surface of the reset telescopic column 32. When the moving block 21 is pushed for clamping operation, the reset spring 31 is stretched. When the external force disappears, the reset spring 31 uses its elastic potential energy to pull the moving block 21 to reset, ensuring that the clamping mechanism 2 can restore to its initial state. The reset telescopic column 32 supports and guides the reset spring 31 to ensure the stability of the reset spring 31. The auxiliary block 33 and the telescopic rod 34 assist in enhancing the stability and reliability of the stabilizing mechanism 3, further ensuring the stability of the moving block 21 during movement and resetting.

[0026] like Figures 1 to 4 As shown, the stabilizing mechanism 3 includes a reset spring 31, a reset telescopic column 32, an auxiliary block 33 and a telescopic rod 34. The reset spring 31 is sleeved on the surface of the reset telescopic column 32, and the interior of the auxiliary block 33 is connected to one end of the telescopic rod 34. One end of the reset spring 31 and the auxiliary block 33 are both connected to the front of the moving block 21, and the other end of the reset spring 31 is connected to one side of the inside of the fixed frame 1. The limiting mechanism 4 includes a limit spring 41 and a limit frame 42. The number of limit frames 42 and limit springs 41 is equal, and two are provided. One end of the two limit springs 41 is connected to the inner side walls of the two limit frames 42, one side of the two limit frames 42 is fixedly connected to the fixed frame 1, and the other end of the two limit springs 41 is connected to one side of the two power plates 23.

[0027] The above scheme is adopted: the limit spring 41 plays the role of limiting and assisting in resetting the power plate 23. When the power plate 23 moves, the limit spring 41 is compressed or stretched. When the clamping operation is completed, it assists the power plate 23 to return to its original position. The limit frame provides an installation position for the limit spring 41 to ensure the working stability of the limit spring 41. At the same time, it is also fixedly connected to the fixed frame 1 to ensure the stability of the entire limit mechanism 4.

[0028] The working principle and usage process of the utility model are as follows: when the sensor needs to be fixed, by pushing the moving block 21, the sliders 22 on both sides of the moving block 21 slide in the power grooves of the power plate 23, thereby driving the two power plates 23 to move in the slide grooves on both sides of the fixed frame 1, and the raised block 231 at one end of the power plate 23 slides in the groove at one end of the fixed frame 1, which plays a guiding and stabilizing role. As the power plate 23 moves, the clamping block 24 at one end thereof approaches each other to achieve clamping and fixing of the sensor. In this process, the stabilizing mechanism 3 composed of the reset spring 31 and the reset telescopic column 32 plays a buffering and resetting role. When the moving block 21 moves, the reset spring 31 will be stretched. When the external force disappears, the reset spring 31 pulls the moving block 21 to reset through elastic potential energy. The auxiliary block 33 and the telescopic rod 34 further enhance the stability. At the same time, the limit spring 41 in the limit mechanism 4 plays a role of limiting and auxiliary resetting for the power plate 23.
