Description

Technical Field

[0001] The utility model belongs to the technical field of potentiometers, and in particular relates to a potentiometer. Background Art

[0002] A potentiometer is an adjustable electronic component consisting of a resistor and a rotating or sliding system. By changing the position of the moving contact on the resistor, the potentiometer can obtain a voltage between the moving contact and the fixed contact that is closely related to the position of the moving contact.

[0003] Potentiometers include straight-slide push-pull potentiometers, which feature a base and a slider that moves left and right within the base. This allows the slider to move left and right to change the potentiometer's resistance. However, this type of structure is prone to physical damage during transportation or customer use. If the slider is struck, the slider will transfer the impact force to the slider, which in turn will transfer the impact force to the base, causing physical damage to the internal structure of the base. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a potentiometer, including a panel and:

[0005] A variable resistance base, which is fixedly arranged on the rear side of the panel;

[0006] A sliding piece, which is slidably arranged on the rear side of the variable resistance base;

[0007] A sliding groove is provided on the panel;

[0008] An L-shaped piece, wherein the horizontal plate of the L-shaped piece is slidably arranged in a sliding groove, and the vertical plate of the L-shaped piece is provided with a groove matching the sliding piece, and one end of the sliding piece is located in the groove;

[0009] A slider, which is fixedly arranged at the front end of the horizontal plate of the L-shaped piece;

[0010] A limiting component, which is provided on the L-shaped piece and is used to limit the position of the L-shaped piece;

[0011] A support assembly, which is provided on the panel and is used to support the L-shaped piece;

[0012] The protection component is arranged on the panel and is used for protecting the L-shaped piece.

[0013] Furthermore, the limiting component includes:

[0014] A protruding piece, wherein the horizontal plate of the L-shaped piece is bent to form a protruding piece;

[0015] Wherein, the panel is located between the slider and the protruding piece.

[0016] Furthermore, the support assembly includes:

[0017] a support plate fixedly disposed on the rear side of the panel;

[0018] Wherein, the lower surface of the L-shaped piece contacts the upper surface of the support plate.

[0019] Furthermore, the protection component includes:

[0020] A protective shell, which is fixedly arranged on the rear side of the panel;

[0021] The protective shell houses the support plate, the L-shaped sheet, the sliding sheet and the variable resistor base cover.

[0022] Furthermore, the protective shell and the panel are detachably connected via screws.

[0023] Furthermore, it also includes:

[0024] a slot provided on the rear side of the slider;

[0025] Wherein, the front side of the transverse plate of the L-shaped piece is interference-fitted with the slot of the slider.

[0026] Furthermore, it also includes:

[0027] An arc-shaped groove is provided on the front side of the slider.

[0028] The beneficial effects of the present invention are:

[0029] 1. By setting a slider to drive the slider to move on the variable resistance base through the L-shaped piece, when the slider is hit, the impact force will not be transmitted to the slider, thereby preventing the slider from causing damage to the interior of the variable resistance base.

[0030] 2. By setting a protrusion and positioning the panel between the slider and the protrusion, the forward and backward movement of the L-shaped piece is restricted. When the L-shaped piece moves forward, the protrusion will contact the panel. When the L-shaped piece moves backward, the slider will contact the panel, making the position of the L-shaped piece more stable.

[0031] 3. By setting up the support plate, a supporting effect is played on the installation and placement of the L-shaped piece. When installing the L-shaped piece and the slider, the horizontal plate of the L-shaped piece can be placed on the support plate first, and the L-shaped piece can be pushed so that the front end of the L-shaped piece protrudes from the front side of the panel, and then the slider and the front end of the L-shaped piece can be installed. When the L-shaped piece is in use, the support plate can support the horizontal plate of the L-shaped piece to prevent the L-shaped piece from tilting due to its own weight, thereby causing the slider to tilt, so that the horizontal plate of the L-shaped piece and the slider are always in a horizontal state, making the overall appearance more beautiful.

[0032] 4. By setting up a protective shell, and the protective shell covers the support plate, L-shaped piece, sliding piece and variable resistor base, when the rear side of the panel is hit, the protective shell protects the support plate, L-shaped piece, sliding piece and variable resistor base, so that when the front and back sides of the panel are hit, the components inside the variable resistor base are not easily damaged, thereby improving the overall safety.

[0033] 5. Since the protective shell and the panel are detachably connected by screws, even if the protective shell is damaged due to a hard collision, as long as the internal components are not damaged, a new protective shell can be replaced to restore the protective effect, thereby extending the overall service life and providing better protection performance.

[0034] 6. By setting up a slot, it is convenient to plug and install with the front side of the L-shaped piece. The slider is made of plastic and has a certain deformation ability. After the sliding groove of the slider is forced to plug with the front side of the L-shaped piece, the front side of the horizontal plate of the L-shaped piece and the slot of the slider can be interference fit.

For ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn to scale. Technologies, methods, and devices known to a person of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely illustrative and not limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] Example 1:

[0045] This embodiment provides a potentiometer, including a panel 1, and further including:

[0046] A variable resistance base 2 is fixedly arranged on the rear side of the panel 1;

[0047] The slider 3 is arranged on the rear side of the variable resistance base 2 for sliding left and right;

[0048] A sliding groove 4 is provided on the panel 1;

[0049] An L-shaped piece 5, wherein the horizontal plate of the L-shaped piece 5 is slidably arranged in the sliding groove 4, and the vertical plate of the L-shaped piece 5 is provided with a groove 6 matching the sliding piece 3, and one end of the sliding piece 3 is located in the groove 6;

[0050] Slider 7, which is fixedly arranged at the front end of the horizontal plate of the L-shaped piece 5;

[0051] A limiting component, which is provided on the L-shaped piece 5 and is used to limit the position of the L-shaped piece 5;

[0052] A support assembly, which is provided on the panel 1 and is used to support the L-shaped piece 5;

[0053] The protection component is provided on the panel 1 and is used to protect the L-shaped piece 5 .

[0054] In this technical solution, when the position of the slide 3 needs to be adjusted, the slider 7 can be moved left and right. The slider 7 drives the L-shaped piece 5 to move left and right. The L-shaped piece 5 drives one end of the slide 3 to move left and right through the groove 6, thereby adjusting the position of the slide 3. The vertical plate of the L-shaped piece 5 is at a 90° angle to one end of the slide 3. When the vertical plate of the L-shaped piece 5 moves forward and backward, it will not drive the slide 3 to move forward and backward.

[0055] During logistics transportation or use, if the slider 7 is hit, the slider 7 will drive the L-shaped piece 5 to move toward the rear side of the panel 1, so that the groove 6 of the L-shaped piece 5 will move backward relative to the slide 3. However, since the groove 6 of the L-shaped piece 5 is not fixedly connected to the slide 3, the vertical plate of the L-shaped piece 5 will not drive the slide 3 to move forward and backward when it moves back and forth, so that when the slider 7 is hit, the impact force will not be transmitted to the slide 3, thereby avoiding the slide 3 from causing damage to the inside of the variable resistor base 2.

[0056] Through this structural design, a slider 7 is provided to drive the slider 3 to move on the variable resistor base 2 through the L-shaped piece 5, so that when the slider 7 is hit, the impact force will not be transmitted to the slider 3, thereby preventing the slider 3 from causing damage to the interior of the variable resistor base 2.
