Description

Technical Field

[0001] This utility model relates to the field of potentiometer technology, and in particular to a rotary potentiometer with an adjustable rotation angle. Background Technology

[0002] A potentiometer typically consists of a resistive element and a movable brush. The resistive element is made of materials such as metal or carbon film and has a fixed resistive characteristic. The brush is a movable contact that moves across the resistive element by rotating or sliding, thereby changing the contact area with the element and thus affecting the resistance value. When the brush moves, a resistance value or voltage proportional to the displacement is obtained at the output terminal. A potentiometer has three terminals, so it can be used as a three-terminal or two-terminal device. As a two-terminal device, a potentiometer can be considered a variable resistor for current control in a circuit. As a three-terminal device, a potentiometer is more often used as a voltage divider, where the desired output voltage is obtained by adjusting the position of the brush.

[0003] For example, Chinese Patent No. CN212032778U discloses a potentiometer, including a potentiometer body, the potentiometer body having a potentiometer base, and a potentiometer handle provided on the potentiometer base, which changes the resistance between the functional pins of the potentiometer by shaking; the potentiometer handle is a hollow rotary handle, and an LED light is provided in the middle of the rotary handle.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The rotary potentiometers described above all have a fixed rotation angle, which cannot meet the needs of specific occasions requiring special angles. For example, in controlling air conditioning temperature, lighting brightness and volume, and airport elevation and tilt angle, the potentiometer needs to be adjusted to different angles.

[0034] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] Please refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a rotary potentiometer with an adjustable rotation angle, comprising: a potentiometer assembly 1 with adjustable angle limit; a potentiometer adjustment assembly 2 for adjusting the potentiometer assembly 1 mounted on the top of the potentiometer assembly 1; a potentiometer positioning assembly 3 for limiting the angle adjustment of the potentiometer adjustment assembly 2 mounted on the potentiometer adjustment assembly 2; and a potentiometer limiting assembly 4 for limiting the rotation of the potentiometer adjustment assembly 2 mounted on the potentiometer adjustment assembly 2.

[0036] By adopting the above technical solution, during the installation process, the different angle requirements of the potentiometer in different places can be met by replacing the angle adjustment plate 301 with different angles. At the same time, by setting the limit bearing 403, the problem of the original potentiometer structure shaking can be solved, the feel and life of the potentiometer extension shaft 202 during use can be improved, and by setting the potentiometer mounting component 5, the installation of potentiometer component 1, potentiometer adjustment component 2, potentiometer positioning component 3 and potentiometer limit component 4 can be facilitated. The simple structural design also greatly reduces the difficulty and cost of installation.

[0037] To facilitate the installation of the potentiometer body 102, in this embodiment: the potentiometer assembly 1 includes a potentiometer mounting plate 101, the potentiometer body 102 is mounted on the bottom of the potentiometer mounting plate 101, and a potentiometer adjustment shaft 103 for rotating and adjusting the potentiometer body 102 is mounted on the top of the potentiometer mounting plate 101.

[0038] To facilitate the rotation and adjustment of the potentiometer mounting plate 101, in this embodiment: the potentiometer adjustment assembly 2 includes a connecting rotating block 201 fixedly connected to the top of the potentiometer adjustment shaft 103, a potentiometer extension shaft 202 fixedly connected to the top of the connecting rotating block 201, and a positioning pin 203 fixedly connected to the edge of the top of the connecting rotating block 201.

[0039] In order to limit the positioning pin 203, in this embodiment, the potentiometer positioning assembly 3 includes an angle adjustment plate 301. The center of the angle adjustment plate 301 is provided with a groove 302 coaxial with the potentiometer extension shaft 202. On the angle adjustment plate 301 and on both sides of the groove 302, there are slots 303 that cooperate with the positioning pin 203.

[0040] In order to limit the potentiometer extension shaft 202 and thus increase the stability of the rotation of the potentiometer extension shaft 202, in this embodiment: the potentiometer limiting component 4 includes a bearing mounting base 401, and positioning sleeves 402 are fixedly connected to both sides of the bottom of the bearing mounting base 401. A limiting bearing 403 matching the potentiometer extension shaft 202 is installed at the center of the bearing mounting base 401.

[0041] To facilitate the assembly and disassembly of the potentiometer positioning component 3, in this embodiment: the potentiometer assembly 1 is also equipped with a potentiometer mounting component 5 for fixing the potentiometer assembly 1, the potentiometer positioning component 3 and the potentiometer limiting component 4. The potentiometer mounting component 5 includes mounting bolts 501.

Fixing nuts 502 are threadedly connected to the mounting bolts 501.

[0042] The working principle of this utility model is as follows: During use, the potentiometer adjustment shaft 103 is rotated by the potentiometer extension shaft 202, and the positioning pin 203 is rotated from one slot 303 to another slot 303, thereby realizing the positioning adjustment of the potentiometer body 102.

[0043] During installation, the angle adjustment plate 301 can be replaced with one of different angles to meet the different angle requirements of the potentiometer in different locations, such as... Figure 5 As shown, it can rotate the positioning pin 203 from one slot 303 to another slot 303, a rotation of 240°, making it suitable for lighting brightness control and volume control, such as... Figure 6As shown, it can rotate 270° from one slot 303 to the other slot 303. At the same time, a 300° angle adjustment plate 301 can be set, which can be used to adjust the airport elevation and tilt angle. It can be used for air conditioning temperature control. Therefore, by disassembling the angle adjustment plate 301 and replacing it with angle adjustment plates 301 of different angles, it can be adapted to the needs of different equipment.

[0044] Meanwhile, by setting a limit bearing 403, the potentiometer extension shaft 202 is limited, increasing the stability of the potentiometer extension shaft 202 rotation, which can solve the problem of the original potentiometer structure shaking, and enhance the feel and lifespan of the potentiometer extension shaft 202 during use. Furthermore, by setting a potentiometer mounting component 5, it is convenient to install the potentiometer component 1, potentiometer adjustment component 2, potentiometer positioning component 3 and potentiometer limit component 4. Therefore, it is convenient to disassemble and replace the angle adjustment plate 301. In addition, the simple structural design also greatly reduces the difficulty and cost of installation.
