Description

Technical Field

[0001] This utility model belongs to the field of membrane switch technology, specifically relating to a protection structure for the output terminal of a membrane switch. Background Technology

[0002] A membrane switch is an integrated operating system combining button functions, indicating elements, and an instrument panel. It consists of four parts: a panel, an upper circuit, an insulating layer, and a lower circuit. When the membrane switch is pressed, the contacts in the upper circuit deform downwards, making contact with the plates in the lower circuit to conduct electricity. When the finger is released, the contacts in the upper circuit rebound, the circuit breaks, and the loop triggers a signal. Currently, with the increasing application of membrane switches in various industries, the requirements for high-quality membrane switches in end products are becoming increasingly stringent.

[0003] Existing membrane switches typically require the output terminal to be connected to the device during use. This connection often results in the output terminal being bent. Prolonged bending of the output terminal can affect the switch's performance, potentially causing it to break and rendering the switch ineffective. Furthermore, the output terminal is usually welded to the switch; accidental pulling can cause it to break. Additionally, existing membrane switches tend to accumulate oil and grease on their surface, which can penetrate the switch over time, leading to malfunction and rendering the switch unusable. Utility Model Content

[0004] The purpose of this invention is to provide a protective structure for the output end of a membrane switch, which can effectively fix the membrane switch and effectively clean the surface of the membrane switch to prevent oil stains from penetrating the membrane switch and causing it to fail; at the same time, it can effectively fix the output end to prevent extreme bending of the output end, which could lead to damage to the output end.

[0005] The specific technical solution adopted by this utility model is as follows: A membrane switch output terminal protection structure includes a mounting base, a fixing groove is provided on the back of the mounting base, a membrane switch is fixed in the fixing groove, and sliding grooves are provided on both sides of the mounting base. A cleaning mechanism is slidably connected inside the sliding groove, and one end of the mounting base is rotatably connected to the protection mechanism. The cleaning mechanism includes a cleaning roller brush, which is fixed to the outside of a sliding rod. The two ends of the sliding rod are slidably connected to sliding grooves on both sides, and the outside of the sliding rod is fixedly connected to one end of a protective plate. The other end of the protective plate is slidably connected to the inside of the mounting base. The protection mechanism includes multiple drive cylinders, the interior of each drive cylinder being threadedly connected to one end of a drive rod, the other end of each drive rod being fixedly connected to one end of a protection plate, and a fixing plate being rotatably connected to one side of the protection plate.

[0006] Furthermore, one end of the mounting base is provided with multiple rotating holes, and multiple driving cylinders are rotatably connected to the multiple rotating holes respectively, and the outer side of the multiple driving cylinders is provided with anti-slip texture.

[0007] Furthermore, a cleaning groove is provided on the outer side of the other end of the mounting base, and a collection box is fitted on the outer side of the cleaning groove. The top of the collection box is slidably connected to the outer side of the other end of the mounting base.

[0008] Furthermore, the cleaning mechanism also includes a cleaning scraper, which is slidably disposed inside the cleaning groove.

[0009] Furthermore, one side of the fixing plate is rotatably connected to one side of the protection plate via a rotating pin, and the other side of the fixing plate is engaged with the other side of the protection plate. The output terminal of a membrane switch is slidably connected between the protection plate and the fixing plate.

[0010] Furthermore, protective pads are fixed to the side of the protective plate and the fixing plate that are slidably connected to the output terminal of the membrane switch, and the protective pads are made of rubber.

[0011] The technical effects achieved by this utility model are as follows: This utility model discloses a protective structure for the output terminal of a membrane switch. By setting up a cleaning mechanism, a cleaning roller brush cleans the surface of the membrane switch, effectively removing residual stains and preventing stains from penetrating the switch surface and damaging the internal components, thus effectively improving the safety of the membrane switch. At the same time, the protective plate can protect the switch when it is not in use, preventing external oil and water stains from directly contacting the membrane switch and causing damage, thus effectively extending the service life of the membrane switch.

[0012] This utility model discloses a protective structure for the output end of a membrane switch. By setting a protective mechanism, the protective plate and the fixing plate squeeze and fix the output end of the membrane switch, effectively preventing bending and breakage at the connection between the output end and the membrane switch. At the same time, by fixing the output end, it can effectively prevent personnel from accidentally pulling the output end, which could lead to breakage with the membrane switch. Through the cooperation of the drive cylinder and the drive rod, the fixing plate and the protective plate can be driven to squeeze the bent part of the output end, effectively completing the bending recovery.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1 to 4 As shown, a membrane switch output terminal protection structure includes a mounting base 10, a fixing groove 11 is provided on the back of the mounting base 10, a membrane switch is fixed in the fixing groove 11, and sliding grooves 12 are provided on both sides of the mounting base 10. A cleaning mechanism 20 is slidably connected inside the sliding grooves 12, and one end of the mounting base 10 is rotatably connected to the protection mechanism 30. The cleaning mechanism 20 includes a cleaning roller brush 21, which is fixed to the outside of a sliding rod 22. The two ends of the sliding rod 22 are slidably connected to the sliding grooves 12 on both sides, and the outside of the sliding rod 22 is fixedly connected to one end of a protective plate 23. The other end of the protective plate 23 is slidably connected to the inside of the mounting base 10. The protection mechanism 30 includes multiple drive cylinders 31, the interior of each drive cylinder 31 is threaded to one end of a drive rod 32, the other end of each drive rod 32 is fixedly connected to one end of a protection plate 33, and a fixed plate 34 is rotatably connected to one side of the protection plate 33.

[0017] In this embodiment, it should be noted that the fixing groove 11 is adapted to the membrane switch, and a pneumatic suction cup is also fixed to the back of the mounting base 10, which can effectively connect with the surface of the device. This is a conventional technical means and will not be described in detail here. When the mounting base 10 is adsorbed and connected to the device, it can effectively fix the outside of the membrane switch. It should also be noted that the outer side of the cleaning roller brush 21 is slidably connected to the surface of the membrane switch. When there is oil residue on the surface of the membrane switch after use, pulling the protective plate 23 will drive the sliding rod 22 to slide inside the sliding groove 12, and effectively drive the cleaning roller brush 21 on the outside of the sliding rod 22 to clean the surface of the membrane switch, effectively removing oil and water stains from the surface of the membrane switch. When the membrane switch is not in use, the protective plate 23 protects the switch, effectively preventing water and oil stains from directly contacting it and causing malfunction. Simultaneously, the protective mechanism 30 effectively adjusts the protective plate 33 and the fixed plate 34, protecting the output end and preventing bending. Specifically, rotating the drive cylinder 31 and engaging the threaded action with the drive rod 32 within it effectively adjusts the drive rod 32, thereby adjusting the protective plate 33 fixedly connected to it. The protective plate 33, in conjunction with the fixed plate 34, compresses the output end, facilitating the restoration of any bent sections.

[0018] like Figure 2 , Figure 3 As shown, one end of the mounting base 10 has multiple rotating holes 101, and multiple drive cylinders 31 are rotatably connected to the multiple rotating holes 101 respectively. The outer side of the multiple drive cylinders 31 is provided with anti-slip texture. When the drive cylinder 31 rotates, by rotating with the rotating holes 101, it can ensure stable cooperation with the drive rod 32. The drive rod 32 drives the protective plate 33 to make stable adjustment. The anti-slip texture increases the friction when the drive cylinder 31 rotates, ensuring that the adjustment is accurate and stable.

[0019] like Figure 2 , Figure 4 As shown, a cleaning groove 13 is provided on the outer side of the other end of the mounting base 10, and a collection box 14 is fitted on the outer side of the cleaning groove 13. The top of the collection box 14 is slidably connected to the outer side of the other end of the mounting base 10. The cleaning groove 13 can effectively guide the oil and water stains cleaned by the cleaning roller brush 21, and the collection box 14 can collect the stains to ensure that the stains do not drip onto the surface of the equipment.

[0020] like Figure 2 As shown, the cleaning mechanism 20 also includes a cleaning scraper 24, which is slidably disposed inside the cleaning groove 13; the cleaning scraper 24 is used to clean the cleaning roller brush 21 and the stains remaining inside the cleaning groove 13.

[0021] In a preferred embodiment, based on the first embodiment, when the protective plate 23 drives the sliding rod 22 and the cleaning roller brush 21 to move, the cleaning roller brush 21 cleans the surface of the membrane switch, effectively cleaning the oil and water stains on the surface of the membrane switch; when it moves to the inside of the cleaning groove 13, the oil and water stains enter the collection box 14 through the cleaning groove 13; then, by using the cleaning scraper 24, the surface of the cleaning roller brush 21 can be scraped to ensure that the stains remaining on the outside of the cleaning roller brush 21 are cleaned; at the same time, the stains remaining in the cleaning groove 13 can be cleaned; when there are many stains in the collection box 14, the collection box 14 can be removed to facilitate the cleaning of the stains in the collection box 14, ensuring that the collection box 14 can effectively collect stains for a long time.

[0022] like Figure 3 , Figure 4 As shown, one side of the fixing plate 34 is rotatably connected to one side of the protection plate 33 via a rotating pin, and the other side of the fixing plate 34 is engaged with the other side of the protection plate 33. The output end of the membrane switch is slidably connected between the protection plate 33 and the fixing plate 34. It should be noted that when the fixing plate 34 and the protection plate 33 are engaged, the output end of the membrane switch can be effectively squeezed to ensure that the bent part of the output end of the membrane switch is flattened. At the same time, the output end can be protected to prevent bending and breakage at the connection between the output end and the membrane switch.

[0023] Preferably, protective pads are fixed on the side of the protective plate 33 and the fixing plate 34 that are slidably connected to the output terminal of the membrane switch. The protective pads are made of rubber. The protective pads can effectively protect the output terminal, prevent hard materials from damaging the output terminal, and ensure the stability and safety of the signal transmission at the output terminal.

[0024] The working principle of this utility model is as follows: When protection of the membrane switch output terminal is required, the mounting base 10 is placed on the outside of the membrane switch and fixed to the surface of the device by adsorption; simultaneously, rotating the drive cylinder 31 moves the drive rod 32 and the protective plate 33 through the thread action; at the same time, by engaging the fixing plate 34 with the protective plate 33, the output terminal can be fixed to prevent bending damage. Furthermore, by adjusting the position of the protective plate 33 and the fixing plate 34, the bent area of ​​the output terminal can be compressed and restored; when the membrane switch surface has residual stains and water stains after use, pulling the protective plate 23 can move the sliding rod 22. 2. When sliding and adjusting within the sliding groove 12, it can effectively drive the cleaning roller 21 fixed on its outer side to clean the surface of the membrane switch, ensuring that oil and water stains are effectively removed and preventing them from penetrating into the membrane switch and causing control failure. When the cleaning roller 21 cleans the stains into the cleaning groove 13, the cleaning scraper 24 can be used to scrape the stains remaining on the surface of the cleaning groove 13 and the cleaning roller 21, so that the stains enter the collection box 14. When the membrane switch is not in use, the protective plate 23 is slidably connected to the inside of the mounting base 10, which can effectively protect the surface of the membrane switch and ensure that external water stains and oil stains will not enter the protective plate 23 and damage the membrane switch.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
