Description

Technical Field

[0001] This utility model relates to the field of micro switches, and in particular to a waterproof installation structure for micro switches. Background Technology

[0002] A micro switch is a small, sensitive electrical switch that can trigger the opening and closing of a circuit through a tiny mechanical displacement. A plunger-type micro switch is one such type, typically consisting of a guide sleeve, with one end of the trigger head slidingly inside the guide sleeve and the other end positioned at the desired installation location. For example, in infusion pumps used in the medical field, the infusion tubing needs to be securely fixed. Loosening of the infusion tubing can affect the operation of the equipment and delay surgical treatment. Therefore, a plunger-type micro switch is installed at the infusion tubing installation location to monitor for loosening in real time. When the silicone membrane in the pressure chamber of the injection pipeline is damaged, the injection liquid will flow out from the pressure chamber seat of the injection pipeline. The outflowing injection liquid will flow directly to the mounting hole of the plunger-type micro switch and the plunger-type micro switch. Because there is a gap between the trigger head and the guide head of the plunger-type micro switch when they slide relative to each other, the liquid can easily enter the plunger-type micro switch through the gap, or enter the equipment through the mounting hole of the plunger-type micro switch along the guide sleeve. This can cause abnormal operation or even short circuit damage to the micro switch or the electrical components inside the equipment due to liquid corrosion, thereby causing equipment failure and affecting the normal use of the equipment.

The technical solution adopted by this utility model to solve its technical problems is as follows: A waterproof mounting structure for a micro switch includes a micro switch, which is fixed to a baffle plate, which is fixed to a mounting plate. The baffle plate is fitted onto a guide sleeve of the micro switch. One end of a trigger head is slidably disposed inside the guide sleeve, and the other end of the trigger head passes through the mounting plate. A first waterproof rubber ring and a second waterproof rubber ring are provided between the baffle plate and the mounting plate. The first waterproof rubber ring is fitted onto the guide sleeve, and the second waterproof rubber ring is fitted onto the trigger head.

[0004] Furthermore, the baffle is recessed in the middle to form a first groove, and a first through hole is provided at the bottom of the first groove. The baffle is sleeved on the guide sleeve through the first through hole. The outer wall of the guide sleeve is provided with threads, and a nut is provided in the first groove. The nut is threadedly connected to the guide sleeve to fix the micro switch on the baffle.

[0005] Furthermore, the four corners of the baffle are fixed to the mounting plate with screws, and the front end of the baffle is in close contact with the rear end of the mounting plate.

[0006] Furthermore, the first waterproof rubber ring is disposed in the first groove, and the rear end of the first waterproof rubber ring abuts against the front end of the nut.

[0013] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "a waterproof installation structure for a micro switch" is provided in conjunction with the accompanying drawings.

[0014] See Figures 1-3 In this embodiment, the waterproof mounting structure of the micro switch includes a micro switch 100, which is fixed to a baffle 200, which is fixed to a mounting plate 300. Preferably, the mounting plate 300 is a side wall of the equipment. The baffle 200 is sleeved on the guide sleeve 101 of the micro switch 100. One end of the trigger head 102 is slidably disposed inside the guide sleeve 101, and the other end of the trigger head 102 passes through the mounting plate 300 to protrude on the outside of the mounting plate 300, so that after the components are installed on the outside of the mounting plate 300, the micro switch 100 can confirm that the components are installed in place. A first waterproof rubber ring 201 and a second waterproof rubber ring 202 are provided between the 0 and the mounting plate 300. The first waterproof rubber ring 201 is fitted onto the guide sleeve 101 to prevent liquid from flowing into the equipment along the outer wall of the guide sleeve 101 and causing a short circuit. The second waterproof rubber ring 202 is fitted onto the trigger head 102 to prevent liquid from entering the micro switch 100 along the gap between the trigger head 102 and the guide sleeve 101 and causing a short circuit. This micro switch waterproof installation structure is designed with two layers of waterproof protection to meet the waterproof installation requirements of equipment that operates in some liquid environments.

[0015] See further Figure 2 and Figure 3 In this embodiment, the baffle 200 is recessed in the middle to form a first groove 203. A first through hole 204 is provided at the bottom center of the first groove 203, penetrating the baffle 200. The baffle 200 is sleeved on the guide sleeve 101 through the first through hole 204. The outer wall of the guide sleeve 101 is provided with threads, and a nut 205 is provided in the first groove 203. The nut 205 is threadedly connected to the guide sleeve 101 to fix the micro switch 100 on the baffle 200. It should be noted that there are two nuts 205 in this embodiment. This ensures that the nuts 205 are tightly fitted and prevents the micro switch 100 from falling off due to the loosening of one nut 205. Of course, in other embodiments, the number of nuts 205 can be one or more, depending on the actual needs.

[0016] More specifically, in this embodiment, the four corners of the baffle 200 are fixed to the mounting plate 300 with screws. The front end face of the baffle 200 is in close contact with the rear end face of the mounting plate 300. The front end face of the baffle 200 is provided with an annular groove 206, and a waterproof strip is provided in the annular groove 206. The waterproof strip is pressurized between the baffle 200 and the mounting plate 300 to prevent liquid from entering the equipment along the gap between the baffle 200 and the mounting plate 300, as a third layer of waterproof protection.

[0017] See further Figure 3 In this embodiment, the first waterproof rubber ring 201 is disposed in the first groove 203. The rear end of the first waterproof rubber ring 201 abuts against the front end of the nut 205, and the front end face of the first waterproof rubber ring 201 protrudes from the front end face of the baffle 200, so that the first waterproof rubber ring 201 is pressed between the baffle 200 and the mounting plate 300. The first waterproof rubber ring 201 is deformed under pressure, which improves the waterproof sealing performance. Furthermore, the first waterproof rubber ring 201 squeezes the nut 205, further preventing the nut 205 from loosening.

[0018] See further Figure 2 In this embodiment, a second groove 301 is provided on the rear end face of the mounting plate 300, and a second through hole 302 is provided at the bottom of the second groove 301, which penetrates the mounting plate 300. The trigger head 102 passes through the second through hole 302 and passes through the mounting plate 300 to expose the trigger head 102. The second waterproof rubber ring 202 is provided in the second groove 301. During installation, the second waterproof rubber ring 202 is pressed into the second groove 301 to improve the waterproof sealing of the trigger head 102.

[0019] More specifically, in this embodiment, the first waterproof rubber ring 201, the second waterproof rubber ring 202, and the waterproof rubber strip are all made of silicone material, which has good deformation ability and waterproof performance.
