[0018] 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.
[0019] Example
[0020] Please see Figure 1-3This embodiment provides the following technical solution: a testing device for testing the opening and closing of an electrical box, including a mounting frame 1, a swing frame 2, a push-pull frame 3 and a pull rope 4. The swing frame 2 is rotatably connected to the mounting frame 1. The left end of the swing frame 2 is rotatably connected to the mounting frame 1 through a fixed shaft 5, so that the swing frame 2 can rotate around the fixed shaft 5.
[0021] A push-pull frame 3 is fixedly connected to the swing frame 2, and a pull rope 4 is fixedly connected to the push-pull frame 3. The other end of the pull rope 4 is detachably connected to the door body. The push-pull frame 3 and the pull rope 4 work together to form the opening and closing structure of the door body. Through the push-pull frame 3 and the pull rope 4, the door body can be repeatedly opened and closed on the electrical box. The number of times the door body is opened and closed can be counted, and the service life of the door body can be estimated. Thus, a plan for regular lubrication, tightening or component replacement can be formulated, reducing the risk of sudden failure of the electrical box.
[0022] like Figure 2 As shown, it also includes a reciprocating swing mechanism for driving the swing frame 2 to swing back and forth. The reciprocating swing mechanism includes a geared motor 9, a rotating frame 10, and a connecting frame 11. The geared motor 9 is fixedly connected to the mounting frame 1. The output shaft of the geared motor 9 is connected to the rotating frame 10. The connecting frame 11 is hinged on the rotating frame 10. The other end of the connecting frame 11 is hinged to the swing frame 2. During the process of the geared motor 9 driving the swing frame 2 to rotate in a circle, the connecting frame 11 limits the swing frame 2, thereby causing the swing frame 2 to drive the push-pull frame 3 to perform reciprocating swing motion. At this time, when the push-pull frame 3 rotates in the direction of the rotating frame 10, the pull rope 4 can pull the door to open. When the push-pull frame 3 rotates away from the rotating frame 10, the push-pull frame 3 can push the door to close.
[0023] The rotating frame 10 and the connecting frame 11 are rotatably connected by locking bolts 12. The rotating frame 10 is provided with an adjustment groove 13 for the locking bolts 12 to move. Under the action of the adjustment groove 13, the position of the end of the connecting frame 11 on the rotating frame 10 can be adjusted so that the connecting frame 11 is closer to or further away from the output shaft of the geared motor 9. By adjusting the position of the frame, the swing range of the swing frame 2 can be changed.
[0024] like Figure 2 As shown, in some embodiments, the connecting frame 11 can be a bearing connecting rod, with the front end of the bearing connecting rod hinged to the swing frame 2 and the rear end of the bearing connecting rod hinged to the rotating frame 10.
[0025] It also includes an opening and closing counting mechanism for detecting the number of times the door is opened and closed by the push-pull frame 3. The opening and closing counting mechanism includes a detection frame 6, a detector 7, and a counter 8. The detection frame 6 is fixedly connected to the mounting frame 1, and the detector 7 and the counter 8 are fixedly connected to the detection frame 6. When the push-pull frame 3 rotates towards the rotating frame 10 around the fixed shaft 5, the detector 7 detects the passing push-pull frame 3 and transmits the detected signal to the counter 8. The counter 8 processes the signal and displays it digitally on the display screen, thereby completing the counting of the number of times the door is opened and closed. In some embodiments, the detector 7 can be a photoelectric sensor that works using the photoelectric effect. When the swing frame 2 passes by the photoelectric sensor, it will block or reflect light, thereby triggering the sensor to work.
[0026] The power terminals of detector 7 and counter 8 are both connected to the power supply equipment, and detector 7 and counter 8 are electrically connected to each other.
[0027] The working principle of this utility model is as follows: When in use, the distribution box to be used is fixed in the corresponding position, and the movable end of the pull rope 4 is fixed on the door. By turning on the switch, the reduction motor 9 is started, which drives the rotating frame 10 to rotate in a circle on the mounting frame 1. Under the action of the connecting frame 11, the swing frame 2 drives the push-pull frame 3 to swing back and forth around the fixed shaft 5. During the swing of the push-pull frame 3, when the push-pull frame 3 rotates towards the rotating frame 10, the pull rope 4 is taut and can pull the door to open. When the push-pull frame 3 rotates away from the rotating frame 10, the push-pull rod contacts the door and applies external force to the door to close it.
[0028] Meanwhile, as the push-pull frame 3 reciprocates around the fixed axis 5, when the push-pull frame 3 passes the detector 7, the detector 7 transmits the detected signal to the counter 8. The counter 8 processes the signal and displays it on the display screen in digital form. Thus, the number of times the swing frame 2 swings can be counted to complete the counting of the number of times the door opens and closes.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
