Description

Technical Field

[0001] The utility model relates to the technical field of electronic membrane switches, in particular to a protection structure for an electronic membrane switch. Background Technique

[0002] A membrane switch is an operating system that integrates button functions, indicating elements, and instrument panels. It has the characteristics of being thin and light in volume, having a rigorous structure, and producing less noise when pressed. It is widely used in various fields, such as in electronic communication, electronic measurement instruments, industrial control, medical equipment, the automotive industry, intelligent toys, household appliances, etc. The membrane switch is relatively fragile, so a protection structure is needed to protect the membrane switch.

[0003] The existing patent (Publication No.: CN218730572U) discloses a protection structure for an electronic membrane switch, including an installation frame and an electronic membrane switch. An electronic membrane switch is arranged inside the installation frame. An annular groove is opened inside the installation frame. Air is injected into the annular groove through a small air supply machine, and with the cooperation of multiple groups of evenly distributed nozzles, the air is sprayed out to form an air surface on the upper surface of the film layer, effectively blocking the entry of dust. In the process of implementing this solution, it is found that the following problems exist in the prior art and have not been well solved: The above device blows air inside the installation frame through an air supply machine to prevent dust from entering the inside of the installation frame. However, after pressing the electronic membrane switch for a long time, the buttons on the upper side of the electronic membrane are prone to damage, which may lead to problems such as poor contact of the electronic membrane switch. Summary of the Invention

[0004] In order to improve the problem that the buttons on the upper side of the electronic membrane are prone to damage after pressing the electronic membrane switch for a long time, which may lead to problems such as poor contact of the electronic membrane switch, the utility model provides a protection structure for an electronic membrane switch.

[0005] The utility model provides a protection structure for an electronic membrane switch, adopting the following technical scheme:

[0006] A protection structure for an electronic membrane switch includes a protection frame. The switch body is slidably connected to the inside of the top surface of the lower protection frame, and the upper protection frame is slidably connected to the top of the lower protection frame;

[0007] Chutes are opened on both the front and rear sides of the top surface of the lower protection frame. Sliders are slidably connected to the inside of the chutes. The top of the sliders is fixedly connected to the bottom of the upper protection frame. A fixing member is movably inserted into the bottom of the lower protection frame.

[0008] Through the above technical solution, it is convenient to reduce the direct contact between the user and the switch body, reduce the occurrence of poor contact of the switch body, and can quickly fix the electronic membrane switch on the wall.

[0009] Optionally, in the above protection structure for an electronic membrane switch, the shapes of the slider and the inner part of the chute are both T-shaped, and a slot is opened at the bottom of the vertical block of the T-shaped slider, and the side surface of the fixing member is slidably connected to the inside of the slot.

[0010] Through the above technical solution, it is convenient for the T-shaped slider to slide vertically inside the chute with a T-shaped inner part.

[0011] Optionally, in the above protection structure for an electronic membrane switch, the fixing member includes a C-shaped rod. The two vertical rods of the C-shaped rod are movably inserted into the lower side of the lower protection frame. The side surface of the vertical rod of the C-shaped rod is slidably connected to the inside of the slot. A tension spring is fixedly connected to the top of the cross bar of the C-shaped rod, and the top end of the tension spring is fixedly connected to the bottom of the lower protection frame.

[0012] Through the above technical solution, it is convenient to stretch the C-shaped rod downward to release the fixation of the vertical rod of the C-shaped rod on the slot, so that the upper protection frame can drive the two sliders to slide inside the chute, and then quickly open the lower protection frame and the upper protection frame.

[0013] Optionally, in the above protection structure for an electronic membrane switch, a T-shaped block is movably inserted into the side surface of the cross bar of the C-shaped rod. A fixing groove is opened on the side surface of the vertical block of the T-shaped block. Compression springs are fixedly connected to the side surfaces of the two cross blocks of the T-shaped block, and one end of each compression spring is fixedly connected to the side surface of the cross bar of the C-shaped rod.

[0014] Through the above technical solution, it is convenient to fix the electronic membrane switch on the bracket on the wall through the fixing groove opened inside the T-shaped block and the cross bar of the C-shaped rod.

[0015] Optionally, in the above protection structure for an electronic membrane switch, a rectangular groove is opened on the upper side of the inner wall of the upper protection frame, and a transparent acrylic plate is slidably connected to the side surface of the inner wall of the rectangular groove.

[0016] Through the above technical solution, it is convenient for the user to press the button on the upper side of the switch body through the transparent acrylic plate.

[0017] Optionally, in the above protection structure for an electronic membrane switch, a rectangular through groove is opened on the left side inside the lower protection frame, and the materials of the lower protection frame and the upper protection frame are both acrylic.

[0018] Through the above technical solution, it is convenient that the lower protection frame and the upper protection frame made of acrylic are light in weight and have corrosion resistance.

[0019] Optionally, in one of the above protection structures for an electronic membrane switch, the sides of the lower protection frame and the upper protection frame are both rounded.

[0020] Through the above technical solution, the lower protection frame and the upper protection frame that are easy to be rounded reduce the possibility of the corners being broken after falling to the ground.

[0021] In summary, the present utility model includes at least one of the following beneficial effects:

[0022] Place the switch body in the lower protection frame. By placing the transparent acrylic plate in the upper protection frame, drive the two sliders of the upper protection frame to slide to the left side of the inner wall of the chute. Protect the switch body through the upper protection frame and the lower protection frame. Move the two vertical rods of the C-shaped rod into the slots to fix the upper protection frame and the lower protection frame. Furthermore, it reduces the direct contact between the user and the switch body and reduces the occurrence of poor contact of the switch body.

[0023] Pre-install a fixing frame on the wall panel. Move the T-shaped block upward to squeeze the two compression springs, so that the fixing groove in the middle of the T-shaped block moves to the upper side of the cross bar of the C-shaped rod. Secondly, insert the fixing groove into the side of the fixing frame, release the T-shaped block, and drive the T-shaped block to reset downward through the compression spring, so that the top of the cross bar of the C-shaped rod and the inside of the fixing groove clamp the fixing frame, and the electronic membrane switch can be quickly fixed on the wall surface.
