Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a medical circuit board that can be quickly replaced. Background Technology

[0002] Circuit boards are core components that provide mechanical assembly support and electrical connections for various electronic systems, and also carry out signal transmission, signal reception, and power supply for electronic devices. Currently, circuit boards need protection during use, especially medical equipment which is related to human life and requires better protection. Even if they break, they need to be easier and simpler to replace. However, current medical circuit boards are similar to conventional circuit boards, with poor shock absorption and protection capabilities. Moreover, replacement requires the removal of more than four screws, which can delay treatment in critical moments. Therefore, we propose a medical circuit board that can be quickly replaced. Utility Model Content

[0003] The main objective of this invention is to provide a quick-replaceable medical circuit board, which can effectively solve the problems in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quick-replaceable medical circuit board includes a PCB board, a pre-installation slot, and a buffer fixing structure. The upper and lower surfaces of the PCB board, and near the two rear corners, are fixedly fitted with snap-fit ​​structures. Fixing screws are interspersed on the surface of the buffer fixing structure.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Example 1: like Figure 1-5 As shown, a quick-replaceable medical circuit board includes a PCB board 1, a pre-installation slot 2, and a buffer fixing structure 4. The upper and lower surfaces of the PCB board 1, and near the two rear corners, are fixedly installed with snap-fit ​​structures 3. The surface of the buffer fixing structure 4 is provided with fixing screws 5. The snap-fit ​​structure 3 includes a snap-fit ​​spring 31, a pressure spring 32, and a stop block 33. The pressure spring 32 is fixedly installed on the inner side of the open end of the snap-fit ​​spring 31, and the stop block 33 is fixedly installed on one end of the snap-fit ​​spring 31. The snap-fit ​​spring 31 of the snap-fit ​​structure 3 snaps into the pre-installation slot 2, which serves to secure the two corners of the PCB board 1. On the other hand, because the snap-fit ​​spring 31 and the pressure spring 32 have a certain elasticity, they can play a role in shock absorption and buffering when encountering vibration, thereby protecting the PCB board 1 and the electronic components on it. In addition, the pressure spring 32 is set to prevent the snap-fit ​​spring 31 from easily deforming under force, that is, it requires a large force to deform it so that it can be snapped into the pre-installation slot 2.

[0015] The surface of the PCB board 1 has mounting slots 11 on both sides of the snap-fit ​​structure 3. The mounting slots 11 are designed to allow the snap-fit ​​structure 3 to be inserted into the pre-installation slot 2 without obstruction. At the same time, the opening of the pre-installation slot 2 is provided with an angled opening to ensure the firmness and stability of the pre-installation slot 2 structure.

[0016] The buffer fixing structure 4 includes a fixed square post 41, an insertion hole 42, upper and lower spring pieces 43, an L-shaped plate 44, side buffer spring pieces 45, and front buffer spring pieces 46. The fixed square post 41 has an insertion hole 42 in the middle. An L-shaped plate 44 is fixedly installed in the middle of the outer surface of the fixed square post 41. Upper and lower spring pieces 43 are fixedly installed on the outer surface of the fixed square post 41 above and below the L-shaped plate 44. Side buffer spring pieces 45 and front buffer spring pieces are fixedly installed on the surface of the L-shaped plate 44 near both ends. 46; The side buffer spring 45 is used to abut against the side of the PCB board 1. The front buffer spring 46 abuts against the front of the PCB board 1. The upper and lower springs 43 abut against the upper and lower surfaces of the PCB board 1 respectively. The upper and lower springs 43, the side buffer springs 45 and the front buffer springs 46 can all play a buffering role on the PCB board 1 while being fixed and abutting. The fixing screw 5 passes through the through hole 42 and is fixed in the screw hole inside the medical device housing to fix the fixing square post 41, thereby fixing the entire buffer fixing structure 4.

[0017] The fixing screw 5 is movably inserted into the insertion hole 42; this arrangement is used to fix the fixing square column 41.

[0018] The pre-installation slot 2 is pre-set inside the medical device housing and is integrally formed with the medical device housing. The inside of the medical device housing is also provided with screw holes for connecting and fixing screws 5.

[0019] It should be noted that this utility model is a quick-replaceable medical circuit board. The pre-installation slot 2 and screw holes are pre-set inside the medical device housing. When installing the PCB board 1, simply align the two snap-fit ​​spring tabs 31 on the PCB board 1 with the ports of the pre-installation slot 2 inside the medical device housing and insert them. After insertion, the stop block 33 limits the snap-fit ​​structure 3, preventing it from being fully inserted, thus leaving a certain buffer space. Then, simply snap the front corner of the PCB board 1 between the two upper and lower spring tabs 43 of the buffer fixing structure 4, with the side buffer spring tab 45 attached to the side of that corner. Similarly, the other corner is snapped in the same way. After snapping, simply pass the fixing screw 5 through the insertion hole 42 and fix it to the corresponding screw hole to secure it. Conversely, when disassembling, simply remove the two fixing screws 5 for quick disassembly. The snap-fit ​​structure 3 and the buffer fixing structure 4 both provide good buffer protection for the PCB board 1. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
