Description

Technical Field

[0001] This utility model relates to the field of potentiometer assembly technology, and more specifically, to an assembly structure for a potentiometer connector. Background Technology

[0002] A potentiometer is a resistive element with three leads whose resistance can be adjusted according to a certain rule. A potentiometer typically consists of a resistive element and a movable brush. When the brush moves along the resistive element, a resistance value or voltage proportional to the displacement is obtained at the output terminal. A potentiometer can be used as either a three-terminal or two-terminal element. The latter can be considered a variable resistor; because its function in the circuit is to obtain an output voltage proportional to the input voltage (applied voltage), it is called a potentiometer. However, existing potentiometer assembly devices are inconvenient for fixing circular potentiometers.

[0003] To address the aforementioned issues, specifically the technical problem of existing potentiometer assembly devices being inconvenient for fixing circular potentiometers, extensive research revealed a precision positioning device for potentiometer assembly (patent publication number CN210757381U). This device includes a bottom mechanism, a support mechanism, a limiting mechanism, and a positioning mechanism. The support mechanism is inserted into the top of the bottom mechanism, and the limiting mechanism is fixedly connected to the bottom of the bottom mechanism. The limiting mechanism engages with the support mechanism, and the positioning mechanism is inserted into the top of the support mechanism. In this precision positioning device, the positioning mechanism only fixes the bottom of the potentiometer body; during potentiometer assembly, this device does not affect the potentiometer's position. The top of the device body is positioned so as not to affect the assembly of the potentiometer. By inserting the support mechanism and the positioning mechanism, the positioning mechanism can be easily disassembled. When assembling the potentiometer, the positioning mechanism that matches the shape and size of the potentiometer is selected and directly inserted into the tray. Then, the potentiometer body is positioned and fixed for assembly, which improves the versatility of the device. However, the technical solution provided by this patent requires different positioning mechanisms to be replaced when assembling potentiometers of different sizes so that the positioning mechanism matches the potentiometer. This results in a lot of time being wasted when the factory changes the type of potentiometer and has to spend a lot of time replacing the positioning mechanism.

[0004] This invention can be used to clamp potentiometers of different sizes and adjust the height of devices. Utility Model Content

[0016] 1.

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0024] Please see Figure 1-5 In this embodiment of the present invention, an assembly structure for a potentiometer connector includes: a base 1, a height adjustment mechanism fixedly installed at the center of the top of the base 1, a top plate 9 fixedly connected to the height adjustment mechanism, and a clamping mechanism 10 installed at the top of the top plate 9. The clamping mechanism 10 includes: a mounting shell 1001, a clamping block 1003, a limiting straight groove 1005, a moving rod 1008, a turntable 1010, a limiting arc groove 1011, and a rotating shaft 1012. The rotating shaft 1012 is fixedly connected to the center of the top of the top of the top plate 9, and the turntable 1010 is rotatably connected to the outside of the rotating shaft 1012. The top of the turntable 1010 has several limiting arc grooves 1011, and the moving rod 1008 is installed in the limiting arc groove 1011. The clamping block 1003 is fixedly connected to the top of the moving rod 1008. A mounting shell 1001 is fitted on the outer side of the turntable 1010. Several limiting straight grooves 1005 are opened through the top of the mounting shell 1001, and a moving rod 1008 is installed in the limiting straight groove 1005. This achieves the effect of clamping potentiometers of different sizes, thus facilitating the assembly of potentiometers. In use, the potentiometer is fixed by placing it in the center of the clamping block 1003. When it is necessary to clamp potentiometers of different sizes, the turntable 1010 is rotated. The turntable 1010 drives the moving rod 1008 to move through the limiting arc groove 1011. Under the action of the limiting straight groove 1005, the moving rod 1008 moves along the limiting straight groove 1005, thereby changing the position of the clamping block 1003 from the center of the top plate 9, so that the assembly can clamp potentiometers of different sizes.

[0025] In this embodiment of the utility model, limiting blocks 1009 are fixedly connected to the left and right sides of the center of the side of the moving rod 1008. The center of the limiting straight groove 1005 is provided with a sliding groove that fits with the limiting block 1009. The cross-section of the limiting blocks 1009 on the left and right sides of the side of the moving rod 1008 is T-shaped, which achieves the effect of limiting the displacement of the moving rod 1008. Through the limiting blocks 1009 and the sliding groove, the moving rod 1008 can only move along the sliding groove and will not rotate, thus avoiding the situation where the clamping block 1003 rotates during the adjustment and use, and cannot clamp the central potentiometer.

[0026] In this embodiment of the utility model, a connecting rod 1006 is fixedly connected to the side of the turntable 1010, and a rotating rod 1007 is fixedly connected to the other end of the connecting rod 1006. A moving groove is provided on the side of the mounting shell 1001 to facilitate the movement of the connecting rod 1006, thereby facilitating the rotation of the turntable 1010. By pushing the rotating rod 1007, the turntable 1010 can be rotated through the connecting rod 1006.

[0027] In this embodiment of the utility model, a spring 1014 is installed inside the rotating rod 1007. The top end of the spring 1014 is fixedly connected to the inside of the rotating rod 1007, and a limiting rod 1013 is fixedly connected to the bottom end of the spring 1014. The bottom end of the limiting rod 1013 is a smooth spherical surface, and several limiting holes 1004 are equidistantly arranged around the top end of the top plate 9. This achieves the effect of increasing the torque required for the rotation of the turntable 1010 to prevent the turntable 1010 from rotating automatically. In daily use, the spring 1014 is adjusted by... The elastic force of the spring 1014 can press the limiting rod 1013 into the limiting hole 1004, thereby restricting the rotation of the turntable 1010. When the rotating rod 1007 needs to be rotated to adjust the position of the clamping block 1003, the bottom end of the limiting rod 1013 is a smooth spherical surface, which allows the limiting rod 1013 to be squeezed into the rotating rod 1007. At this time, it is only necessary to apply a certain force to the rotating rod 1007 to move the limiting rod 1013 out of the limiting groove so that the rotating rod 1007 can rotate.

[0028] In this embodiment of the present invention, a sponge pad 1002 is fixedly connected to the potentiometer clamping surface of the clamping block 1003 to prevent the clamping block 1003 from wearing down the potentiometer.

[0029] In this embodiment of the utility model, the height adjustment mechanism includes: a lower threaded sleeve 5, a threaded rod 6, a rotating block 7, and an upper threaded sleeve 8. The lower threaded sleeve 5 is fixedly connected to the center of the top of the base 1. The rotating block 7 is installed on the top of the lower threaded sleeve 5. The upper threaded sleeve 8 is installed on the top of the rotating block 7. A top plate 9 is fixedly connected to the top of the upper threaded sleeve. A threaded rod 6 with opposite rotation directions is fixedly connected to both the top and bottom ends of the rotating block 7. The lower threaded sleeve 5 and the upper threaded sleeve 8 have threaded sleeves that fit with the threaded rod 6 through them, so as to achieve the effect of adjusting the height of the device. When in use, rotating the rotating block 7 will drive the threaded rod 6 to rotate, so that the threaded rod 6 moves into or out of the lower threaded sleeve 5 and the upper threaded sleeve 8, thereby changing the distance between the lower threaded sleeve 5 and the upper threaded sleeve 8, thus changing the height of the entire device.

[0030] In this embodiment of the utility model, guide rods 3 are fixedly connected to the four corners of the bottom end of the top plate 9. A guide rod sleeve 2 is sleeved on the outer side of the bottom end of the guide rod 3. A guide hole that fits the guide rod 3 is opened through the inside of the guide rod sleeve 2. A base 1 is fixedly connected to the bottom end of the guide sleeve, so as to avoid the top plate 9 being rotated along with the rotating block 7.

[0031] In this embodiment of the utility model, a plurality of support ribs 4 are fixedly connected to the bottom side of the lower threaded sleeve 5, and a base 1 is fixedly connected to the bottom of the support ribs 4, thereby enhancing the stability of the lower threaded sleeve 5.

[0032] In this embodiment of the utility model, the side of the rotating block 7 is provided with several anti-slip grooves to avoid slipping when rotating the rotating block 7.

[0033] Working principle: In use, the potentiometer is fixed by placing it in the center of the clamping block 1003. The spring force of the spring 1014 presses the limiting rod 1013 into the limiting hole 1004, thus restricting the rotation of the turntable 1010. When different sizes of potentiometers need to be clamped, the turntable 1010 is rotated. The turntable 1010 drives the moving rod 1008 to move through the limiting arc groove 1011. Under the action of the limiting straight groove 1005, the moving rod 1008 moves along the limiting straight groove 1005. Because the bottom end of the limiting rod 1013 is a smooth spherical surface, the limiting rod 1013 can be squeezed into the rotating rod 1007. At this time, only a certain force needs to be applied to the rotating rod 1007 to... The limiting rod 1013 moves out of the limiting groove to allow the rotating rod 1007 to rotate, thereby changing the position of the clamping block 1003 from the center of the top plate 9. This allows the assembly to clamp potentiometers of different sizes. Through the limiting block 1009 and the slide groove, the moving rod 1008 can only move along the slide groove and will not rotate. This avoids the situation where the clamping block 1003 rotates during adjustment and cannot clamp the central potentiometer. When the height needs to be adjusted, the rotating block 7 is rotated, thereby driving the threaded rod 6 to rotate. This causes the threaded rod 6 to move into or out of the lower threaded sleeve 5 and the upper threaded sleeve 8, changing the distance between the lower threaded sleeve 5 and the upper threaded sleeve 8, thereby changing the height of the entire device.
