Description

Technical Field

[0001] This utility model relates to the field of personnel management technology, and in particular to a circuit board mounting structure for personnel management equipment. Background Technology

[0002] With the acceleration of urbanization and the increasing demands for quality of life, the cleaning industry plays a crucial role in maintaining public hygiene and creating a comfortable environment. To address the problems of inefficiency, lack of transparency, and scheduling difficulties inherent in traditional cleaning personnel management methods, and to meet the high standards of modern cleaning services, personnel management equipment is being used to manage personnel.

[0003] In the existing technology, personnel management equipment includes a housing, a display screen, and a PCB circuit board. The PCB circuit board is fixed inside the housing with screws. When the PCB circuit board needs to be repaired, it needs to be disassembled with the help of tools, which is cumbersome and therefore has room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circuit board mounting structure for personnel management equipment. Its advantage lies in improving the ease of PCB circuit board installation and removal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circuit board mounting structure for personnel management equipment includes a housing, a display screen is disposed on one side of the bottom inner wall of the housing, and a PCB circuit board is disposed on the other side of the bottom inner wall of the housing. The housing is fixed to the PCB circuit board from the four corners by four mounting components.

[0007] The installation assembly includes a positioning tube fixed to the inner wall of the housing. A positioning ring is provided on the outer wall of the positioning tube. A fixing cap is sleeved on the top of the positioning tube. Sliding grooves are provided on both sides of the inner wall of the top of the fixing cap. A push post is slidably connected to the inner wall of the sliding groove. The two push posts are connected by a return spring. A connecting rod is provided at the bottom of the push post. The connecting rod has an L-shaped structure. A locking block is provided at the end of the connecting rod away from the push post. A locking hole is provided on the inner wall of the opening of the positioning tube. The locking block is adapted to the locking hole.

[0008] The above technical solution involves placing the four corners of the PCB circuit board onto the positioning tubes during use, with the bottom of the PCB circuit board in contact with the positioning ring. Holding the push-buttons causes them to move relative to each other, retracting the two connecting rods together. The fixing cap is then placed on the surface of the positioning tube. When the bottom of the fixing cap contacts the top of the PCB circuit board, the push-buttons are released, causing them to move in opposite directions. The locking block then enters the locking hole, fixing the fixing cap onto the positioning tube. The combined action of the fixing cap and the positioning ring secures the PCB circuit board. This simple operation improves the ease of PCB circuit board installation and removal.

[0009] The present invention is further configured such that the end of the pressing column away from the reset spring has a spherical structure.

[0010] The above technical solution, with its spherical structure at one end, makes the end of the push-button smoother, preventing any discomfort when pressing.

[0011] The present invention is further configured such that the side of the card block near the card hole has an arc-shaped structure.

[0012] The above technical solution, with its arc-shaped structure on one side, makes the side of the card block smooth, facilitating its entry into the positioning tube and improving operational convenience.

[0013] The present invention is further provided with a blocking plate on both sides of the inner wall of the positioning tube, and the blocking plate is located below the card hole.

[0014] The above technical solution involves setting up a blocking plate to easily block the block and prevent it from moving too much inside the positioning tube.

[0015] The present invention is further provided that a buffer pad is provided on the top of the positioning ring.

[0016] Through the above technical solutions, the setting of the buffer pad can provide a good cushioning effect and avoid damage to the PCB circuit board.

[0017] The present invention is further configured such that the buffer pad is made of silicone material.

[0018] Through the above technical solutions, the silicone cushioning pad has good elasticity and insulation, preventing leakage from the PCB circuit board.

[0019] The present invention is further provided with a pressure plate at the bottom of the fixing cap, and a buffer plate at the bottom of the pressure plate.

[0020] Through the above technical solutions, the buffer plate can buffer the PCB circuit board from the top, thus improving the protection effect on the top of the PCB circuit board.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This circuit board mounting structure for personnel management equipment is used by placing the four corners of the PCB circuit board onto the positioning tubes, with the bottom of the PCB circuit board in contact with the positioning ring. Hold the push-buttons by hand; the two push-buttons move relative to each other, causing the two connecting rods to retract together. Place the fixing cap on the surface of the positioning tube. When the bottom of the fixing cap contacts the top of the PCB circuit board, release the push-buttons; the push-buttons move in opposite directions, and the locking block enters the locking hole, thus fixing the fixing cap onto the positioning tube. The fixing cap and positioning ring work together to secure the PCB circuit board. The operation is simple, improving the convenience of PCB circuit board installation and removal.

[0023] 2. The circuit board mounting structure for personnel management equipment features a spherical design at one end, which makes the end of the pressing column smooth and avoids hand discomfort when pressing; the arc-shaped design on one side makes the side of the locking block smooth, facilitating the locking block's entry into the positioning tube and improving operational convenience; the blocking plate can easily block the locking block, preventing it from moving too much within the positioning tube.
