Technical Field

[0001] This utility model relates to the field of switch box technology, specifically a mine explosion-proof mobile transformer low-voltage terminal switch box. Background Technology

[0002] The explosion-proof mobile substation low-voltage switch box (commonly known as a low-voltage protection box) is an electrical device used in underground coal mine mobile substations. It is mainly used for monitoring, protecting and controlling the low-voltage side power grid. It is suitable for underground coal mine environments with methane and coal dust explosion hazards. For reference, see announcement number CN218215126U, which describes an explosion-proof and intrinsically safe low-voltage permanent magnet mechanism vacuum feeder switch for mining. It includes a switch housing, a door on the front of the switch housing, an opening in the center of the front of the door, a fixing box on the back of the door, and a matching sliding mounting bracket inside the opening.

[0003] While the aforementioned device effectively protects the display screen, the functionality of the device's enclosure door is relatively limited. It is inconvenient to quickly fix the wiring according to the enclosure door's condition or to quickly disassemble the display screen protection structure, which affects the user experience of the device. Utility Model Content

[0004] The purpose of this invention is to provide a mine-use explosion-proof mobile transformer low-voltage terminal switch box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mine explosion-proof mobile transformer low-voltage terminal switch box includes a switch box body, and a first limiting rail is fixedly connected to the side surface of the switch box body.

[0007] The switch box is provided with a pushing mechanism on its side surface. The pushing mechanism includes a fixed sleeve, a connecting plate, and a sliding seat. The fixed sleeve is fixedly connected to one side surface of the switch box. An electric push rod is fixedly connected inside the fixed sleeve. The connecting plate is fixedly connected to the output end of the electric push rod. The sliding seat is slidably connected to the inside of the first limit rail. A box door is hinged to one end of the sliding seat. The pushing mechanism controls the opening and closing of the box door. A controller is embedded in the rear surface of the box door.

[0008] Furthermore, a second limiting rail is fixedly connected to the other side surface of the switch box body, and a guide plate is fixedly connected to the other side surface of the box door, with the guide plate and the second limiting rail being slidably connected.

[0009] Furthermore, a support frame is fixedly connected to the front surface of the switch box, a rubber buffer pad is fixedly connected to the front surface of the support frame, and a threaded hole is provided on the rear surface of the switch box.

[0010] Furthermore, both sides of the switch box are fixedly connected with wiring pipes, and the lower surface of the wiring pipes is provided with through grooves.

[0011] Furthermore, the pushing mechanism also includes a support base, a lifting plate, and a stud. There are two support bases, which are respectively fixedly connected to the upper surfaces of the sliding seat and the guide plate. The lifting plate is embedded and movably connected to the upper surface of the support base. A limit rod is fixedly connected to the lower surface of the lifting plate. The stud is threadedly connected to the lower surface of the support base.

[0012] Furthermore, a limiting frame is fixedly connected to the front surface of the door, and a transparent acrylic plate is slidably connected to the inner surface of the limiting frame. The transparent acrylic plate protects the controller display screen without affecting the normal use of the display screen on the controller.

[0013] Furthermore, the front surface of the door is provided with a mounting groove, which provides operating space for the installation of the controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By pushing the mechanism to adjust the opening and closing of the box door, it is convenient to open and close the box door and to assist in fixing the wires and transparent acrylic plates entering the switch box from the outside, thereby improving the functionality of the device;

[0016] 2. By manually rotating the stud, the lifting plate will rise under the push of the thread. When the lifting plate rises, it inserts into the through groove, which can help fix the wires inside the wiring pipe. The limit rod passes through the support base and is slidably connected to the support base. The limit rod limits the movement of the lifting plate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a mine explosion-proof mobile low-voltage switch box includes a switch box body 1, and a first limiting rail 101 is fixedly connected to the side surface of the switch box body 1.

[0024] A pushing mechanism 3 is provided on the side surface of the switch box 1. The pushing mechanism 3 includes a fixed sleeve 301, a connecting plate 303, and a sliding seat 304. The fixed sleeve 301 is fixedly connected to one side surface of the switch box 1. An electric push rod 302 is fixedly connected inside the fixed sleeve 301. The connecting plate 303 is fixedly connected to the output end of the electric push rod 302. The sliding seat 304 is slidably connected to the inside of the first limit rail 101. A door 4 is hinged to one end of the sliding seat 304. The pushing mechanism 3 controls the opening and closing of the door 4. A controller 5 is embedded in the rear surface of the door 4.

[0025] Specifically, the switch box 1 is installed on the low-voltage side of the explosion-proof mine transfer device. The first limit rail 101 limits the push mechanism 3. The push mechanism 3 adjusts the opening and closing of the box door 4, which facilitates the opening and closing of the box door 4 and provides auxiliary fixation for the wires and transparent acrylic plate 402 entering the switch box 1 from the outside, thereby improving the functionality of the device. The fixing sleeve 301 is connected to the switch box 1 with the threaded assembly and can be used to install the electric push rod 302. When the electric push rod 302 is started, the output end of the electric push rod 302 can push the connecting plate 303 to move the sliding seat 304, thereby separating the box door 4 from the switch box 1.

[0026] Example 1

[0027] like Figure 1-4As shown, a second limiting rail 102 is fixedly connected to the other side surface of the switch box body 1, and a guide plate 403 is fixedly connected to the other side surface of the box door 4. The guide plate 403 and the second limiting rail 102 are slidably connected. Both sides of the switch box body 1 are fixedly connected to wiring pipes 2, and a through groove 201 is opened on the lower surface of the wiring pipe 2.

[0028] In this embodiment, when the electric push rod 302 pushes the box door 4 to move, the box door 4 drives the guide plate 403 to slide along the second limit rail 102. When the guide plate 403 and the second limit rail 102 separate, one end of the box door 4 can be unfixed, making it easier to open the box door 4 to perform wiring operations inside the switch box 1.

[0029] like Figure 1-4 As shown, the pushing mechanism 3 also includes a support base 305, a lifting plate 306, and a stud 308. There are two support bases 305, which are respectively fixedly connected to the upper surfaces of the sliding seat 304 and the guide plate 403. The lifting plate 306 is embedded and movably connected to the upper surface of the support base 305. The lower surface of the lifting plate 306 is fixedly connected to a limit rod 307. The stud 308 is threadedly connected to the lower surface of the support base 305.

[0030] In this embodiment, manually rotating the stud 308 will cause the lifting plate 306 to rise under the push of the thread. When the lifting plate 306 rises, it will insert into the through groove 201, which will help fix the wires inside the wiring pipe 2. The limiting rod 307 passes through the support base 305 and is slidably connected to the support base 305. The limiting rod 307 limits the movement of the lifting plate 306.

[0031] Example 2

[0032] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to replace the transparent acrylic sheet 402 in Embodiment 1.

[0033] like Figure 1-4 As shown, a limiting frame 401 is fixedly connected to the front surface of the door 4, and a transparent acrylic plate 402 is slidably connected to the inner surface of the limiting frame 401. The transparent acrylic plate 402 protects the display screen of the controller 5 without affecting the normal use of the display screen on the controller 5. A support frame 103 is fixedly connected to the front surface of the switch box body 1, and a rubber buffer pad 104 is fixedly connected to the front surface of the support frame 103. A threaded hole 105 is opened on the rear surface of the switch box body 1, and an installation groove 404 is opened on the front surface of the door 4. The installation groove 404 can provide operating space for the installation of the controller 5.

[0034] In this embodiment, when the door 4 is closed, the transparent acrylic sheet 402 and the rubber buffer pad 104 on the support frame 103 come into contact, so that the transparent acrylic sheet 402 and the limiting frame 401 are tightly connected together. After the door 4 is opened, the upper end of the transparent acrylic sheet 402 is no longer fixed, and the transparent acrylic sheet 402 can be easily taken out.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
