Description

Technical Field

[0001] The utility model relates to the technical field of switch panels, in particular to a portable bottom box structure for a switch panel. Background Technique

[0002] Existing switch boxes generally include three major parts: a switch panel, a switch bottom box, and a wall-mounted bottom box. In order to connect and fix these two parts of the switch panel and the switch bottom box, screws and nuts are generally used for connection. The nut is installed inside the nut post, and the nut post is installed on the bottom plate of the switch bottom box;

[0003] Due to the rapid development of Internet of Things technology, for switch panels of smart homes, central air-conditioning control panels, background music controller panels, etc., there will be more and more switches with strong and weak electricity in the same panel. The circuits of these control panels are more complex than the original switch panels, and require good heat dissipation effects and larger installation spaces to match the use of circuit boards.

[0004] A bottom box structure of a switch panel disclosed in the existing patent (publication number: CN 213277857 U) has a large installation cavity inside the bottom box body, heat dissipation holes are provided at the bottom of the installation cavity, and wire connection holes, first data interface connection holes, second data interface connection holes, and power interface connection holes are provided inside the installation cavity, which can cooperate with the installation of the panel switch to achieve multi-target adjustment and connection, and has good heat dissipation performance and a large installation space.

[0005] However, the above technical solution still has certain defects. When the device is used, it is connected to the panel through a connection card slot and an inverted card slot. After multiple repairs, the connection stability between the connection card slot and the inverted card slot and the panel will decrease. At this time, the panel body is likely to fall off, and the internal components are exposed to the outside, posing a problem to the personal safety of users. Therefore, a portable bottom box structure for a switch panel is proposed. Content of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide a portable bottom box structure for a switch panel to solve the technical problems raised in the above background.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: A portable bottom box structure for a switch panel, including a bottom box, an auxiliary card slot is opened at the top of the bottom box, and an installation mechanism is provided inside the auxiliary card slot;

[0008] The installation mechanism includes an auxiliary clamping block arranged inside the auxiliary clamping groove. A panel is fixed to the top end of the auxiliary clamping block. A knob is installed on the top end of the panel. A transmission rod is fixed to the bottom end of the knob. A wire rope is fixed to the outer wall of the transmission rod.

[0029] The installation mechanism 200 includes an auxiliary clamping block 220 disposed inside the auxiliary clamping slot 110. A panel 210 is fixed to the top end of the auxiliary clamping block 220. A knob 230 is installed on the top end of the panel 210. A transmission rod 240 is fixed to the bottom end of the knob 230. A wire rope 250 is fixed to the outer wall of the transmission rod 240. The other end of the wire rope 250 is fixed to a limiting block 260. One end of the wire rope connected to the limiting block 260 is fixed to a return spring 270. The other end of the return spring 270 is fixed to the outer wall of the frame 280. The limiting block 260 is disposed inside the insertion block 290 and is slidably connected thereto. The insertion block 290 is disposed in the slot 170. The slot 170 is opened at the top end of the installation block 160. The installation block 160 is fixed to the inner wall of the bottom box 100. Limiting grooves 180 are opened at both ends of the inner wall of the slot 170. A connection block 211 is provided at the center position of the bottom end of the panel 210.

[0030] The auxiliary clamping block 220 and the auxiliary clamping slot 110 in the installation mechanism play an auxiliary connection role. The staff rotates the knob 230 to drive the wire rope 250 to contract through the transmission rod 240, so that the limiting block 260 contracts into the insertion block 290. After the insertion block 290 is placed inside the slot 170, release the knob 230, and the limiting block 260 can be inserted into the limiting groove 180 to complete the locking through the return spring 270. And by the insertion block 290 abutting against the blade 150, the square groove is opened for heat dissipation, avoiding the problem that the panel 210 is prone to fall off after multiple repairs, and solving the danger of internal components being exposed outside.

[0031] Please refer specifically to Figures 2 to 4 , the size of the limiting groove 180 matches the size of the limiting block 260 and is slidably connected to the limiting block 260. A through hole is opened on the outer wall of the frame 280, and the size of the through hole matches the size of the wire rope 250.

[0032] The limiting groove 180 allows the limiting block 260 to be displaced and inserted for locking, and the through hole opened on the outer wall of the frame 280 allows the wire rope 250 to move.

[0033] Please refer specifically to Figure 4 and Figure 5 , a wire connection hole 120 is opened at the bottom end of the bottom box 100. A square groove is provided below the wire connection hole 120 and is opened at the bottom end of the bottom box 100. A rotating rod is provided inside the square groove. A blade 150 is fixed to the outer wall of the rotating rod. A counterweight is provided at one end of the blade 150. The connection block 211 is in abutting connection with the blade 150. Multiple function grooves are opened on the surface of the panel 210. A data interface connection hole 130 is provided below the square groove and is opened at the bottom end of the bottom box 100. A power interface connection hole 140 is provided on one side of the data interface connection hole 130 and is opened at the bottom end of the bottom box 100.

[0034] Multiple groups of functional slots are provided for personnel to use. The cable connection hole 120, the data interface connection hole 130 and the power interface connection hole 140 can facilitate the use of the panel. When maintenance is required, the installation mechanism 200 is removed and the blade 150 will be affected by the counterweight block to block the square slot, thereby preventing external impurities from entering. Otherwise, it will open through the resistance of the connection block 211 to dissipate heat.

[0035] When in use, the auxiliary card block 220 in the installation mechanism and the auxiliary card slot 110 play an auxiliary connection role. The staff rotates the knob 230 to drive the rope 250 to shrink through the transmission rod 240, so that the limit block 260 shrinks to the inside of the plug block 290. When the plug block 290 is placed in the slot 170, the knob 230 is released, and the limit block 260 can be inserted into the limit slot 180 to complete the locking through the return spring 270. The plug block 290 contacts the blade 150, thereby opening the square groove to expose the heat dissipation, avoiding multiple repairs of the rear panel The problem that 210 is easy to fall off is solved, which solves the danger of internal components being exposed to the outside; multiple groups of functional slots are provided for personnel to use, and the cable connection hole 120, the data interface connection hole 130 and the power interface connection hole 140 can facilitate the use of the panel. When maintenance is required, the installation mechanism 200 is removed and the blade 150 will be affected by the counterweight block and the square slot will be blocked, thereby preventing external impurities from entering. Otherwise, it will be opened through the resistance of the connecting block 211 for heat dissipation. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
