Description
Technical Field
[0001] This utility model relates to the field of potentiometer technology, and in particular to a dustproof potentiometer. Background Technology
[0002] A dustproof potentiometer is an adjustable resistor specifically designed for dusty environments. It is designed to prevent dust and contaminants from entering the interior and is typically equipped with a sealed housing. This design ensures the potentiometer's long-term stability and accuracy in harsh environments. It is widely used in circuits that require adjusting current or voltage, such as audio equipment and monitor brightness control. By adjusting the potentiometer's resistance, the current or voltage can be controlled, thereby adjusting the device's parameters.
[0003] However, when using dustproof potentiometers, there are sometimes situations where the potentiometer malfunctions and needs to be removed from the external dustproof housing for cleaning and maintenance, which is inconvenient and requires extra time for disassembly and assembly, thus affecting the efficiency of subsequent maintenance. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a dustproof potentiometer.
[0005] This utility model is achieved by the following technical solution: a dustproof potentiometer, including a potentiometer, an adjustment knob rotatably connected to the upper end of the potentiometer, a terminal block fixedly connected to the right end of the potentiometer, a connecting component provided at the left end of the potentiometer, and a protective component provided at the right end of the potentiometer;
[0006] The connecting assembly includes a first protective shell, a sliding groove at the right end of the first protective shell, a sliding frame slidably connected to the inner wall of the sliding groove, a fixed shaft slidably connected to the inner wall of the sliding frame, a spring sleeved on the surface of the fixed shaft, a connecting frame fixedly connected to the right end of the sliding frame, a drive plate fixedly connected to the side end of the sliding frame, the sliding groove being located on the front and rear sides of the potentiometer, the drive plate being slidably connected to the surface of the first protective shell on the side near the sliding frame, the surface of the fixed shaft being fixedly connected to the inner wall of the sliding groove, the spring being located at the lower end of the sliding frame, and the surface of the connecting frame being slidably connected to the inner wall of the first protective shell.
[0007] The above technical solution utilizes the cooperation between the drive plate and the spring to drive the sliding frame and the connecting frame to rise and fall, thereby controlling the connection between the connecting frame and the connecting groove. This design enables convenient assembly and disassembly of the first protective shell and the second protective shell, making subsequent maintenance of the device more convenient and further improving the overall practicality of the device.
[0008] As a further improvement to the above solution, the protective component includes a second protective shell, a connecting groove is provided at the left end of the second protective shell, an installation groove is provided on the inner wall of the second protective shell, the inner wall of the installation groove is slidably connected to the surface of the terminal block, the inner wall of the connecting groove is snapped into the surface of the connecting bracket, and the potentiometer is snapped between the first protective shell and the second protective shell.
[0009] The above technical solution utilizes a second protective shell to cooperate with the first protective shell in providing protection for the intermediate potentiometer, and a design that uses connection slots and mounting slots to provide connection conditions for other components in the device. This makes the subsequent use of the device more convenient and faster, and improves the overall practicality of the device.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This utility model, through the setting of a connecting component, specifically: pulling down the front and rear drive plates causes the sliding frame to slide downwards, and simultaneously the sliding frame causes the connecting frame to slide downwards, thereby releasing the limiting effect of the connecting frame on the connecting groove. At this point, the first protective shell and the second protective shell can be separated, thereby releasing the limiting effect on the intermediate potentiometer. The potentiometer can then be removed for maintenance. After maintenance, the potentiometer is put back, and then the two drive plates are pulled down to lower the connecting frame. At this point, the first and second protective shells are merged again, and the connecting frame is inserted back into the inner wall of the connecting groove. Then, the limiting effect on the drive plates is released, and the sliding frame rebounds under the action of the spring, thereby causing the connecting frame to slide upwards, thus locking the connecting frame back into the inner wall of the connecting groove. This completes the disassembly and assembly of the potentiometer. The design, which uses the cooperation between the drive plate and the spring to drive the sliding frame and the connecting frame to rise and fall, and thereby controls the connection between the connecting frame and the connecting groove, achieves the purpose of convenient disassembly and assembly of the first and second protective shells, making subsequent maintenance of the device more convenient, thereby further improving the practicality of the device.
[0012] This utility model incorporates a protective assembly: after the first and second protective shells on both sides are separated, the limiting effect on the intermediate potentiometer is released. At this point, the potentiometer can be pulled to detach the wiring terminals from the inner wall of the mounting slot for maintenance. After maintenance, the potentiometer is reinserted, and the first and second protective shells on both sides are connected to protect the potentiometer from dust. The design of using the second protective shell in conjunction with the first protective shell to protect the intermediate potentiometer, along with the connection slot and mounting slot to provide connection conditions for other components in the device, makes subsequent use of the device more convenient and quick, improving the overall practicality of the device.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0021] Example:
[0022] Please combine Figure 1-5 A dustproof potentiometer according to this embodiment includes a potentiometer 1, an adjustment knob 2 rotatably connected to the upper end of the potentiometer 1, a terminal block 3 fixedly connected to the right end of the potentiometer 1, a connection component 4 provided at the left end of the potentiometer 1, and a protective component 5 provided at the right end of the potentiometer 1.
[0023] The connecting component 4 includes a first protective shell 401. A sliding groove 402 is provided at the right end of the first protective shell 401. A sliding frame 403 is slidably connected to the inner wall of the sliding groove 402. A fixed shaft 404 is slidably connected to the inner wall of the sliding frame 403. A spring 405 is sleeved on the surface of the fixed shaft 404. A connecting frame 406 is fixedly connected to the right end of the sliding frame 403. A drive plate 407 is fixedly connected to the side end of the sliding frame 403. The design uses the cooperation between the drive plate 407 and the spring 405 to drive the sliding frame 403 and the connecting frame 406 to rise and fall, thereby controlling the connection between the connecting frame 406 and the connecting groove 502. This design achieves the purpose of conveniently assembling and disassembling the first protective shell 401 and the second protective shell 501, making subsequent maintenance of the device more convenient, and thus improving the overall practicality of the device.
[0024] The sliding groove 402 is located on the front and rear sides of the potentiometer 1, and the drive plate 407 is slidably connected to the surface of the first protective shell 401 on the side near the sliding frame 403.
[0025] The surface of the fixed shaft 404 is fixedly connected to the inner wall of the sliding groove 402, and the spring 405 is located at the lower end of the sliding frame 403.
[0026] The protective component 5 includes a second protective shell 501. A connecting groove 502 is provided at the left end of the second protective shell 501, and an installation groove 503 is provided on the inner wall of the second protective shell 501. The design of using the second protective shell 501 to cooperate with the first protective shell 401 to provide protection for the intermediate potentiometer 1, and the connecting groove 502 and the installation groove 503 to provide connection conditions for other components, makes the subsequent use of the device more convenient and quick, and improves the overall practicality of the device.
[0027] The inner wall of the mounting groove 503 is slidably connected to the surface of the terminal block 3, and the inner wall of the connecting groove 502 is snapped into the surface of the connecting bracket 406.
[0028] Potentiometer 1 is snapped between the first protective shell 401 and the second protective shell 501.
[0029] The surface of the connecting bracket 406 is slidably connected to the inner wall of the first protective shell 401.
[0030] The implementation principle of a dustproof potentiometer in this embodiment is as follows: When using the device and performing disassembly and maintenance, first pull down the drive plates 407 on both sides to drive the sliding frame 403 downward. At the same time, the sliding frame 403 drives the connecting frame 406 downward, thereby releasing the limiting effect of the connecting frame 406 on the connecting groove 502. At this time, the first protective shell 401 and the second protective shell 501 can be separated, thereby releasing the limiting effect on the intermediate potentiometer 1. Then, the potentiometer 1 can be pulled to drive the terminal block 3 to separate from the inner wall of the mounting groove 503 for maintenance of the potentiometer 1. After maintenance, the potentiometer 1 and the terminal block 3 are reinserted. Then, the drive plates 407 on both sides are pulled down again to lower the connecting frame 406. At this time, the first protective shell 401 is pulled down again. 01 merges with the second protective shell 501, and at the same time, the connecting bracket 406 is inserted into the inner wall of the connecting groove 502 again. Then, the limit on the drive plate 407 is released. At this time, the sliding bracket 403 rebounds under the action of the spring 405, thereby driving the connecting bracket 406 to slide upward, so that the connecting bracket 406 and the inner wall of the connecting groove 502 are engaged again. This completes the disassembly and assembly of potentiometer 1. The device uses the sliding of the sliding bracket 403 to drive the connecting bracket 406 and the connecting groove 502 to separate and join. This design realizes the purpose of conveniently switching the connection between the first protective shell 401 and the second protective shell 501 on both sides of potentiometer 1. This allows potentiometer 1 to be easily disassembled and maintained when it is damaged in subsequent use, thereby further improving the overall practicality of the device.
[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
