[0002] Power distribution control equipment includes distribution cabinets, distribution panels, distribution boxes, etc., which are mainly used for the distribution and control of electrical energy. The power supply board of the power distribution control equipment is a circuit board used to control and monitor the power supply of the power distribution equipment. Its installation methods include screw installation, welding, plug-in installation, etc.
[0003] For example, Chinese utility model patent with announcement number CN221688048U discloses a power supply board for power distribution control equipment, which includes a power supply board body. Several connecting rings for connecting lines are installed on the surface of the power supply board body. Several circuit connecting pieces are installed in the middle of the power supply board body. Mounting components for assisting the power supply board body in heat dissipation are connected to both sides of the power supply board body.
[0004] Based on the above, the inventors discovered that: The power board in CN221688048U is installed with a pair of mounting components, allowing it to be installed non-adhesively with the power distribution control equipment, thereby improving the heat dissipation of the power board itself. However, since the two mounting components are independently installed, the installation gap and angle need to be measured before each installation; otherwise, the installation of the power board may fail, making it inconvenient to use. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a power board for power distribution control equipment, aiming to achieve a more practical purpose.

In addition, it is equipped with a rotatable and adjustable dustproof component, which can prevent dust from falling directly onto the power board, reduce the problem of dust accumulation on the power board, and play an effective dustproof role.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A power distribution control equipment power board includes a base, a top plate on the top of the base, a power board body centrally located on the opposite side of the base and the top plate, and a dust prevention mechanism located on the front side of the opposite side of the base and the top plate. A pair of mounting feet are fixedly connected to both sides of the base, and a limit plate is fixedly connected to the bottom front side of the base. Sliding blocks are fixedly connected to both ends of the top plate, and a pair of support blocks are fixedly connected to the front side of the top plate.

[0017] 3. Beneficial effects
[0018] Compared with existing technologies, the advantages of this utility model are:
[0019] (1) This solution involves pulling the top plate upward to engage the bottom of the power board body with the snap-fit groove at the bottom of the base, and then releasing the top plate. Under the action of the snap-fit spring, the sliding block drives the top plate to reset, so that the top of the power board body engages with the snap-fit groove on the bottom surface of the top plate, thus completing the installation of the power board. Compared with the existing technology, the setting of the limit snap-fit component allows for quick non-adhesive installation of the power board, which is convenient to operate and improves the efficiency of power board loading and unloading.
[0020] (2) By setting up a dustproof mechanism, the dustproof cover is rotated downward with the limit ring as the rotating axis, so that the snap strip at the bottom of the dustproof cover is snapped with the limit plate, and the position of the dustproof cover is fixed. The dustproof cover prevents dust from falling directly onto the power board body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] Example:
[0028] Please see Figure 1-4 A power distribution control equipment power board includes a base 1, a top plate 2 on the top of the base 1, a power board body 3 centrally located on the opposite side of the base 1 and the top plate 2, and a dust prevention mechanism 4 located on the front side of the opposite side of the base 1 and the top plate 2. A pair of mounting feet 5 are fixedly connected to both sides of the base 1, and a limit plate 6 is fixedly connected to the bottom front side of the base 1. Sliding blocks 8 are fixedly connected to both ends of the top plate 2, and a pair of support blocks 10 are fixedly connected to the front side of the top plate 2. A snap-fit spring 9 is fixedly connected to the top surface of the sliding block 8.
[0029] The dust prevention mechanism 4 includes a dust prevention cover 11. Limiting rings 12 are fixedly connected to the top of the dust prevention cover 11 on both sides, and a set of snap-fit strips 13 are fixedly connected to the bottom of the dust prevention cover 11. An observation window 14 is fixedly connected to the middle of the dust prevention cover 11. The dust prevention mechanism 4 is provided in order to reduce the dust adhering to the power board body 3.
[0030] See Figure 3 Both the bottom of the base 1 and the bottom surface of the top plate 2 are provided with snap-fit grooves 7. The two ends of the power board body 3 are respectively snap-fitted to the two snap-fit grooves 7. First, the base 1 is fixed inside the power distribution control equipment by bolting through the mounting feet 5. Then, the top plate 2 is pulled upward and the power board body 3 is placed inside the base 1 so that its bottom is snap-fitted to the snap-fit grooves 7 at the bottom of the base 1.
[0031] See Figure 2 The sliding block 8 is located on the side of the base 1, close to the inside, and is slidably connected to the base 1. The movement of the top plate 2 causes the sliding block 8 to move simultaneously. The sliding block 8 ensures the stability of the movement of the top plate 2 and compresses the locking spring 9.
[0032] See Figure 3 The end of the snap-fit spring 9 away from the sliding block 8 is fixedly connected to the inner surface of the base 1. When the top plate 2 is released, the sliding block 8 is driven to reset the top plate 2 under the action of the snap-fit spring 9, so that the top of the power board body 3 is snapped into the snap-fit groove 7 on the bottom surface of the top plate 2.
[0033] See Figure 4 Two limiting rings 12 are located inside the two support blocks 10 respectively, and the limiting rings 12 are movably connected to the support blocks 10. The dust cover 11 is rotated downward with the limiting rings 12 as the rotation axis.
[0034] See Figure 1 The front end of the limiting plate 6 is provided with a set of card interfaces. The card strip 13 is set to be connected to the card interface, so that the card strip 13 at the bottom of the dust cover 11 is connected to the limiting plate 6, thus fixing the position of the dust cover 11.
[0035] See Figure 4 The dust cover 11 is L-shaped, and the observation window 14 is located in front of the power board body 3. The dust cover 11 prevents dust from falling directly onto the power board body 3, thus achieving the dust prevention effect.
[0036] In use: First, fix the base 1 inside the power distribution control equipment by bolting through the mounting feet 5. Then, pull the top plate 2 upward and place the power board body 3 inside the base 1, so that its bottom engages with the snap-fit groove 7 at the bottom of the base 1. The movement of the top plate 2 drives the sliding block 8 to move simultaneously, and the sliding block 8 ensures the stability of the movement of the top plate 2. At the same time, the snap-fit spring 9 is compressed, and then the top plate 2 is released. Under the action of the snap-fit spring 9, the sliding block 8 drives the top plate 2 to reset, so that the top of the power board body 3 engages with the snap-fit groove 7 on the bottom surface of the top plate 2, completing the installation of the power board. Finally, using the limit ring 12 as the rotation axis, rotate the dustproof cover 11 downward, so that the snap-fit strip 13 at the bottom of the dustproof cover 11 engages with the limit plate 6, thus fixing the position of the dustproof cover 11. The dustproof cover 11 prevents dust from falling directly onto the power board body 3, achieving a dustproof effect and ensuring the normal operation of the power board.
