Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4 A digital display potentiometer that is easy to disassemble and assemble comprises a digital display potentiometer body 1 and a device bracket 2 arranged at the lower end of the digital display potentiometer body 1. Disassembly structures 3 are installed on both the left and right sides of the digital display potentiometer body 1. The digital display potentiometer body 1 and the device bracket 2 are disassembled and assembled through the disassembly structure 3 (the digital display potentiometer is a prior art and need not be described in detail).

[0024] The disassembly and assembly structure 3 includes a fixing seat 31 and an open groove 32 opened on the surface of the fixing seat 31. A threaded rod 33 is threadedly inserted on the side wall of the fixing seat 31. One end of the threaded rod 33 is connected to a limiting plate 34, and the limiting plate 34 is placed on the inner side of the opening groove 32. A limiting groove 35 is opened on the surface of the opening groove 32. A groove 21 is opened on the surface of the equipment bracket 2, and a limiting card plate 22 is arranged inside the groove 21. When the threaded rod 33 rotates, the limiting plate 34 can be driven to move, and the limiting card plate 22 can be inserted into the limiting groove 35. The position of the digital display potentiometer body 1 can be limited, and the digital display potentiometer body 1 can be fixed on the equipment bracket 2. It does not need to be disassembled and assembled with the help of tools and bolts, and the operation is simple.

[0025] The limit card plate 22 and the limit slot 35 are on the same horizontal line, and the limit card plate 22 and the limit slot 35 are adapted to each other. When the limit plate 34 moves left and right, the limit card plate 22 can be inserted into the limit slot 35, so that the digital display potentiometer body 1 can be restricted on the equipment bracket 2.

[0026] In this embodiment: the digital display potentiometer body 1 is placed on the equipment bracket 2, and the bottom of the limit plate 34 is placed in the groove 21, and then the threaded rod 33 is rotated to move the limit plate 34 so that the limit card plate 22 can slide into the limit groove 35, so that the digital display potentiometer body 1 can be limited on the equipment bracket 2, and the digital display potentiometer body 1 can be fixed on the equipment bracket 2, without the need for tools and bolts to disassemble and assemble, the operation is simple, and the disassembly and assembly are convenient.

[0027] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 3 and Figure 4 The number of the grooves 21 and the limiting clamping plates 22 is consistent with that of the limiting plates 34 , and a magnetic block 23 is embedded on the surface of the limiting clamping plate 22 .

[0028] A reinforcing piece 36 is further provided on one side of the limiting plate 34 , and the reinforcing piece 36 can reinforce the limiting plate 34 and the limiting clamping plate 22 to avoid shaking.

[0029] The reinforcing member 36 includes a knob 361 and a connecting rod 362 arranged on one side of the knob 361. A groove is provided inside the limit plate 34, and a conical tooth A363 and a screw rod 364 are provided in the groove. The other end of the connecting rod 362 is inserted into the limit plate 34 and connected with the conical tooth A363. The outer side of the screw rod 364 is sleeved with a conical tooth B365, and the conical tooth B365 is meshed and connected with the conical tooth A363. The outer side of the conical tooth B365 is sleeved with a threaded sleeve 366, and the lower end of the threaded sleeve 366 is connected to a reinforcing magnetic plate 367 through a rod. When the knob 361 is rotated, the connecting rod 362 and the conical tooth A363 can be driven to rotate, and the transmission of the conical tooth B365 and the conical tooth A363 can drive the screw rod 364 to rotate, so that the threaded sleeve 366 can drive the reinforcing magnetic plate 367 to move downward, so that the limit plate 34 and the limit clamping plate 22 will not shake up and down.

[0030] The reinforcing magnetic plate 367 and the magnetic block 23 are oppositely charged magnets and can attract each other. When the reinforcing magnetic plate 367 moves downward toward the magnetic block 23, the two can attract each other and can achieve a magnetic connection, which can provide additional stability and a good reinforcement effect.

[0031] In this embodiment: when the knob 361 is rotated, the connecting rod 362 and the conical tooth A363 can be driven to rotate, and the screw rod 364 can be driven to rotate through the transmission of the conical tooth B365 and the conical tooth A363, so that the threaded sleeve 366 can drive the reinforcement magnetic plate 367 to move downward. When the reinforcement magnetic plate 367 moves downward and approaches the magnetic block 23, the two can attract each other, and a magnetic connection can be achieved, thereby ensuring the firmness of the connection.

[0032] Working principle: Place the digital display potentiometer body 1 on the equipment bracket 2, and then rotate the threaded rod 33 to move the limit plate 34 so that the limit card 22 can slide into the limit groove 35, and then rotate the knob 361. The transmission of the conical tooth B365 and the conical tooth A363 can drive the screw rod 364 to rotate, and the threaded sleeve 366 drives the reinforcement magnetic plate 367 to move downward. The reinforcement magnetic plate 367 and the magnetic block 23 can be magnetically attracted to ensure the firmness of the connection.
