[0003] Although the existing installation and fixing structure is cost-effective and has advantages such as good stability.
[0004] However, this cost-saving mounting structure has the following disadvantages: the existing PCBA board mounting method is to install it by riveting screws with sheet metal, which mainly affects the cost. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a cost-saving installation and fixing structure, which can effectively solve the problem of the existing PCBA board fixing method, which is based on sheet metal riveting screws, mainly affecting the cost.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a cost-saving installation and fixing structure, including a front shell, a ribbed plate fixedly installed on the inner bottom wall of the front shell, a BOSS column provided on the top of the ribbed plate, and a PCBA assembly board snapped onto the top of the BOSS column.
[0008] Preferably, a mounting groove is provided in the middle of the top surface of the BOSS column, and a mounting screw is threaded into the mounting groove.
[0009] Preferably, threaded through grooves are provided at the four corners of the top surface of the PCBA assembly board, and the threaded through grooves are adapted to the mounting screws.
[0010] Preferably, the outer surface of the front shell is covered with a waterproof membrane to increase water resistance, and electronic components are disposed on the top of the PCBA assembly board.
[0011] Preferably, the top of the ribbed plate is provided with square grooves at equal intervals, and the bottom of the BOSS column is fixedly connected to the top of the intersection of the square grooves.
[0012] Preferably, the ribbed plate is made of a lightweight material, and the bottom of the BOSS column is fixed by welding. Compared with known prior art, the technical solution provided by this utility model has the following beneficial effects: 1. By utilizing the cooperative use of the BOSS column, PCBA component board, and ribbed plate, when installing the PCBA board, personnel can snap the PCBA component board to the top of the BOSS column, and then use the mounting screws 3 to fix the PCBA component board to the top of the BOSS column, making it convenient for personnel to install.
[0013] 2. To reduce the processing and manufacturing costs of the product, sheet metal is replaced by ribbed plates and boss columns, which not only reduces the overall cost of the product but also reduces its weight, making it more convenient for medical staff to use. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The utility model will be further described below with reference to the embodiments.
[0021] Example: Refer to Figures 1 to 4A cost-saving installation and fixing structure includes a front shell 1, a rib plate 4 fixedly installed on the inner bottom wall of the front shell 1, a BOSS column 5 provided on the top of the rib plate 4, threaded through grooves provided at the four corners of the top surface of the PCBA assembly board 2, the threaded through grooves being adapted to the mounting screws 3, a waterproof membrane for increasing waterproofness being attached to the outer surface of the front shell 1, and electronic components being provided on the top of the PCBA assembly board 2.
[0022] When personnel need to install PCBA component board 2, medical staff can directly snap PCBA component board 2 into the bottom of BOSS column 5. Then, medical staff can use the mounting screws 3 to pass through the four corners of the top surface of PCBA component board 2 and rotate it clockwise to quickly install and fix PCBA component board 2, thus facilitating the fixation of PCBA component board 2 by medical staff.
[0023] The top of the BOSS column 5 is snapped with a PCBA component board 2. A mounting groove is opened in the middle of the top surface of the BOSS column 5.
