Technical Field

[0001] This utility model relates to the technical field of ethylene oxide sterilizers, specifically a flipping mechanism. Background Technology

[0002] Ethylene oxide sterilization equipment is a key piece of equipment for manufacturers of disposable sterile medical devices. Its installation, operation, and management have specific requirements. Using ethylene oxide as a sterilizing agent, a broad-spectrum sterilizer, it can kill various microorganisms at room temperature, including spores, tubercle bacilli, bacteria, viruses, and fungi. In pharmaceutical companies, using ethylene oxide sterilizers is a commonly used sterilization method. However, when servicing ethylene oxide sterilizers, it is often difficult to open them quickly and safely, making maintenance extremely cumbersome.

[0003] Based on this, a flipping mechanism is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a flipping mechanism to solve the problem that in the prior art, it is often impossible to open an ethylene oxide sterilizer quickly and safely.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flipping mechanism includes a base plate, a top cover, and a flipping mechanism. The top cover is provided on the top of the base plate, and the flipping mechanism is provided inside the base plate for flipping the top cover for subsequent maintenance. The fixing mechanism is provided inside the base plate for installing the flipping mechanism.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-9 As shown, a flipping mechanism includes a base plate 1, a top cover 2, and a flipping mechanism 3. The top cover 2 is provided on the top of the base plate 1, and the flipping mechanism 3 is provided inside the base plate 1 for flipping the top cover 2 for subsequent maintenance. The fixing mechanism 4 is provided inside the base plate 1 for installing the flipping mechanism 3.

[0029] In one embodiment, such as Figures 4-7As shown, the flipping mechanism 3 includes a parallel upward-moving base 301, a connecting groove 302, a bushing 303, a support rod 304, a connecting plate 305, a parallel upward-moving top bracket 306, a clamping plate 307, a screw 308, a flat washer 309, a spring washer 310, and a nut 311. Two sets of parallel upward-moving bases 301 are provided on the top surface of the base plate 1, and a parallel upward-moving top bracket 306 is provided on the bottom surface of the top cover 2. Two sets of connecting grooves 302 are formed on the surfaces of the parallel upward-moving bases 301 and the parallel upward-moving top bracket 306. Bushings 303 are slidably connected to the inner walls of the two sets of connecting grooves 302. Two sets of support rods 304 and connecting plates 305 are slidably connected to the surfaces of the two sets of bushings 303. The bushings 303 effectively reduce hole wear and increase concentricity. The tops of the two sets of parallel upward-moving bases 301 are fixed... A retaining plate 307 is fixedly connected to limit the position of the support rod 304. A screw 308 is slidably connected to the inner wall of the bushing 303. A flat washer 309 and a spring washer 310 are slidably connected to the surface of the screw 308 to make the fixing of the screw 308 and the nut 311 more stable. One end of the screw 308 is threadedly connected to the nut 311. The bushing 303 is inserted into the connecting groove 302 on the support rod 304, the connecting plate 305, the parallel upward base 301, and the parallel upward top frame 306, so that the support rod 304 and the connecting plate 305 can rotate on the bushing 303. Then, the screw 308 is passed through the flat washer 309, the bushing 303, the spring washer 310, and the nut 311. The nut 311 is turned so that the screw 308 is fixed on the bushing 303 by the nut 311.

[0030] In one embodiment, such as Figure 6 As shown, the inner wall size of the connecting groove 302 matches the outer wall size of the bushing 303. When the bushing 303 slides inside the connecting groove 302, the connecting groove 302 can limit the sliding of the bushing 303 and prevent the bushing 303 from shaking inside the connecting groove 302.

[0031] In one embodiment, such as Figure 6 As shown, screw 308 is a cross-head flat screw, and nut 311 is a non-metallic insert hexagonal lock nut, which can prevent moving parts such as parallel upward base 301, parallel upward top bracket 306, support rod 304 and connecting plate 305 from detaching from bushing 303.

[0032] In one embodiment, such as Figures 8-9As shown, the fixing mechanism 4 includes a fixing groove 401, a first threaded hole 402, a first screw 403, a second threaded hole 404, and a second screw 405. The top surface of the base plate 1 has two sets of fixing grooves 401. A parallel upward-moving base 301 is slidably connected to the inner walls of the two sets of fixing grooves 401. Two sets of first threaded holes 402 are opened on the surface of the parallel upward-moving base 301. A first screw 403 is threadedly connected to the inner wall of the first threaded hole 402. One end of the first screw 403 mates with the base plate 1. Two sets of second threaded holes 404 are opened on both sides of the bottom of the top cover 2. A second screw is threadedly connected to the inner wall of the second threaded hole 404. 405. One end of the second screw 405 engages with the parallel upward-moving top bracket 306. One end of the parallel upward-moving base 301 is inserted into the fixing slot 401. The first screw 403 is turned, and the first screw 403 passes through the first threaded hole 402 and is threadedly connected to the base plate 1, so that the parallel upward-moving base 301 can be fixed on the base plate 1. Then, the parallel upward-moving top bracket 306 is placed in the groove inside the top cover 2. The second screw 405 is turned, and the second screw 405 passes through the second threaded hole 404 and is threadedly connected to the parallel upward-moving top bracket 306, so that the parallel upward-moving top bracket 306 can be fixed on the top cover 2, thereby completing the installation of the flipping mechanism 3.

[0033] In one embodiment, such as Figure 1 As shown, the surface of the base plate 1 is provided with a power distribution panel 5, which is used to distribute power to the ethylene oxide sterilizer.

[0034] In one embodiment, such as Figure 1 As shown, the base plate 1 has multiple sets of positioning holes 6. When the base plate 1 and the top cover 2 are put together, the bolts are turned and the bolts pass through the positioning holes 6 and are threaded to the top cover 2, so that the base plate 1 and the top cover 2 can be fixed together.

[0035] In one embodiment, such as Figure 1 As shown, multiple sets of heat dissipation holes 7 are provided on both sides of the top cover 2 to improve the heat dissipation effect of the ethylene oxide sterilizer.

[0036] Working Principle: The above embodiment discloses a flipping mechanism. In use, the bushing 303 is inserted into the connecting groove 302 on the support rod 304, connecting plate 305, and parallel upward-moving base 301 and parallel upward-moving top frame 306, allowing the support rod 304 and connecting plate 305 to rotate on the bushing 303. Then, the screw 308 passes through the flat washer 309, bushing 303, spring washer 310, and nut 311. Tightening the nut 311 fixes the screw 308 to the bushing 303. One end of the parallel upward-moving base 301 is inserted into the fixing groove 401. Tightening the first screw 403 causes it to pass through the first threaded hole 402 and threadedly connect to the base plate 1, fixing the parallel upward-moving base 301 to the base plate 1. Finally, the parallel upward-moving top frame 306 is placed in the groove inside the top cover 2. Tighten the second screw 405, which passes through the second threaded hole 404 and is threadedly connected to the parallel upward moving top frame 306, so that the parallel upward moving top frame 306 can be fixed on the top cover 2, thereby completing the installation of the flipping mechanism 3. When the base plate 1 and the top cover 2 are together, tighten the bolt, which passes through the positioning hole 6 and is threadedly connected to the top cover 2, so that the base plate 1 and the top cover 2 can be fixed together. When it is necessary to repair the ethylene oxide sterilizer, unscrew the bolt fixing the top cover 2, manually open the top cover 2, so that the flipping device can be opened, one end of the support rod 304 is raised, thereby supporting the top cover 2. When the opening angle of the top cover 2 is greater than 90 degrees, the support rod 304 will touch the clamping plate 307 on the parallel upward moving base 301, so that it can mechanically limit it, so that the top cover 2 can be stable and not fall back, thereby facilitating the repair of the device on the base plate.
