Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable branch boxes, specifically a safety interlocking device for cable branch boxes. Background Technology
[0002] Cable branch boxes are important devices in power systems used for branching, connecting, and distributing electrical energy from cable lines. They are widely used in power distribution networks such as urban power grid upgrades, industrial parks, and residential communities. They can divide a main cable into multiple branch cables, enabling flexible distribution of electrical energy. They also facilitate the inspection and maintenance of cable lines. Cable branch boxes play a vital role in power systems, not only achieving efficient distribution of electrical energy and meeting the electricity needs of different users, but also ensuring the safe and stable operation of the power system. With the continuous development of the power industry, the performance requirements for cable branch boxes are becoming increasingly stringent. In the future, they will develop towards intelligence, miniaturization, and environmental friendliness.
[0003] Currently, cable distribution boxes typically use interlocking devices to lock the boxes. However, these devices require manual locking, and if the locker forgets to lock the box, it can compromise safety and is not practical for current use. Therefore, improvements are needed.

[0022] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.
[0023] A safety locking device for a cable branch box includes a housing 8, a pushing mechanism 2 embedded on the left side of the housing 8, a limiting mechanism 9 embedded on the right side of the housing 8, a connecting plate 10 connected to the right side of the housing 8, a limiting port 11 opened on the right side of the connecting plate 10, a rotating mechanism 1 connected to the bottom surface of the housing 8, and a distance sensor 4 connected to the bottom surface of the housing 8.
[0024] In this embodiment, the rotating mechanism 1 includes a frame 101 connected to the housing 8. A first drive motor 102 is connected to the inner top wall of the frame 101. A rolling bearing 104 is embedded in the bottom surface of the frame 101. A rotating rod 103 is connected to the inner ring of the rolling bearing 104. The output end of the first drive motor 102 is connected to the top end of the rotating rod 103. A take-up roller 105 is connected to the bottom end of the rotating rod 103. The design of the first drive motor 102 and the rotating rod 103 facilitates the take-up roller 105 and the connecting rope to drive the box door closer to the box body, and at the same time facilitates closing the box door.
[0025] In this embodiment, support plates 3 are connected to both the left and right sides of the frame 101. One side of each support plate 3 is connected to the bottom surface of the housing 8. The support plates 3 facilitate the support of the frame 101. The pushing mechanism 2 includes a second drive motor 201 embedded in the housing 8. The output end of the second drive motor 201 is connected to a threaded cylinder 202. A threaded rod 205 is threadedly connected to the inner wall of the threaded cylinder 202. The power provided by the second drive motor 201 facilitates the rotation of the threaded cylinder 202. Based on the cooperation between the threaded cylinder 202 and the threaded rod 205, the threaded rod 205 facilitates the movement of the insertion rod 902. A pressure bearing 203 is connected to the outer surface of the threaded cylinder 202. A support block 204 is connected to the outer surface of the pressure bearing 203. The bottom surface of the support block 204 is connected to the inner bottom wall of the housing 8. The design of the pressure bearing 203 and the support block 204 facilitates the increase of the stability of the threaded cylinder 202.
[0026] In this embodiment, the limiting mechanism 9 includes a slide cylinder 901 embedded in the housing 8. An insertion rod 902 is slidably connected to the inner wall of the slide cylinder 901. The left end of the insertion rod 902 is connected to the right end of the threaded rod 205 through a push plate. The movement of the insertion rod 902 inside the slide cylinder 901 facilitates insertion into the limiting port 11 and can lock the door, which improves safety and solves the problem of forgetting to close the door. A model plate 6 is provided on the top of the housing 8. The bottom surface of the model plate 6 is connected to the upper surface of the housing 8. The model plate 6 makes it easy to identify the model of the device. Two first mounting plates 7 are connected to the upper surface of the housing 8. A second mounting plate 5 is connected to the front of the connecting plate 10. The first mounting plates 7 facilitate the installation of the device on the top wall inside the housing. The design of the second mounting plate 5 facilitates the installation of the connecting plate 10 on the side of the door.
[0027] Working principle: The distance sensor 4 is designed to monitor the distance to the cabinet door. When the monitored distance reaches the preset value, the first drive motor 102 inside the frame 101 starts, and its output end drives the rotating rod 103 to rotate. Since the rotating rod 103 is connected to the frame 101 through the rolling bearing 104, the stability of the rotation is ensured. The rotation of the rotating rod 103 will drive the bottom winding roller 105 to rotate synchronously. The winding roller 105 is connected to the cabinet door through the connecting rope. When the winding roller 105 winds up, the connecting rope pulls the cabinet door closer to the cabinet body.
[0028] At this time, the distance sensor 4 controls the second drive motor 201 to start through the external controller. Its output end drives the threaded cylinder 202 to rotate. Under the support of the pressure bearing 203 and the support block 204, the rotation of the threaded cylinder 202 is more stable. Since the threaded rod 205 is threadedly connected to the inner wall of the threaded cylinder 202, the rotation of the threaded cylinder 202 will be converted into the linear movement of the threaded rod 205, thereby pushing the insertion rod 902 to slide inside the slide cylinder 901. The movement of the insertion rod 902 can be inserted into the limiting port 11 on the connecting plate 10 to complete the locking operation.
[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
