Description

Technical Field

[0001] The present application relates to the technical field of knob structures, and in particular to a tamper-proof threaded knob structure. Background Art

[0002] The widespread and popular design and optimization of knob structures not only significantly improves device operation convenience, but also enhances user experience and reliability. They are particularly popular in a variety of fields, including household appliances and mechanical equipment. Knob structures play a significant role in device safety. However, with the development of technology, further improvements are being made, and the market is increasingly demanding higher requirements for knob structures, especially in terms of safety.

[0003] Utility model patent announcement number CN215487117U discloses an anti-dismantling threaded connector, comprising: a main body, a first stopper, an abutting portion, and a slipping portion. The main body has an end face, and the first stopper is protruding from the outer peripheral surface of the main body to stop a tool when the main body is rotated along a tightening direction. The abutting portion is provided on the outer peripheral surface of the main body to abut the tool. The slipping portion is provided on the outer peripheral surface of the main body and has a slipping surface. Along a loosening direction opposite to the tightening direction, the distance between the slipping surface and the end face gradually increases. When the tool rotates the main body along the loosening direction, the slipping surface abuts the tool and gradually moves away from the end face of the main body, eventually causing the tool to detach from the main body, thereby achieving an anti-dismantling effect. This anti-dismantling threaded connector is only suitable for preventing the tool from being disassembled. When it is manually disassembled, it can still be disassembled. The applicability of the anti-dismantling structure is low. Summary of the Invention

[0004] The purpose of this application is to provide an anti-dismantling threaded knob structure in order to solve the problem that the anti-dismantling structure cannot cope with human disassembly, resulting in low applicability.

[0005] The present application provides a tamper-proof threaded knob structure that adopts the following technical solutions:

[0006] A tamper-proof threaded knob structure includes:

[0007] The knob seat has a first thread and a clamping block on its outer wall, the clamping block protrudes from the surface of the knob seat and is elastically connected to the knob seat;

[0008] The knob cover is sleeved on the outside of the knob base, and the inner wall of the knob cover is provided with a second thread and a snap-in groove. The second thread fits with the first thread to connect the knob base and the knob cover, and the snap-in groove fits with the snap-in block. The snap-in groove has a rotating surface and a snap-in surface. The rotating surface can press the snap-in block to form a snap connection, so that the first thread and the second thread can be rotatably connected. The snap-in surface forms a snap connection with the snap-in block, so that the knob base and the knob cover cannot be rotated and disassembled.

[0009] By adopting the above technical solution, the first and second threads connect the knob base and the knob cover through rotation. During rotation, the engaging block and the engaging slot form an engaging connection. The rotating surface of the engaging slot presses the engaging block when the knob base and the knob cover are rotationally connected, thereby ensuring normal rotational connection. When the knob base and the knob cover rotate in the opposite direction to separate, the engaging block is resisted by the engaging surface of the engaging slot, preventing the knob base from rotating in the opposite direction, thereby achieving the purpose of anti-disassembly. This knob structure automatically forms an engaging anti-disassembly structure after the knob base and the knob cover are rotated to connect. It is easy to operate and the completely locked state makes it difficult to separate even if manually separated, thereby improving the applicability of the anti-disassembly structure.

[0010] Optionally, one side of the clamping block is connected to the knob seat, and the other side is tilted from the surface of the knob seat. The side of the clamping block connected to the knob seat corresponds to the direction of the rotational connection between the knob seat and the knob cover.

[0011] By adopting the above technical solution, the snap-in block is tilted from one side, so that when the knob structure is rotated and connected, the tilted side can be pressed by the snap-in slot, and when the knob structure is rotated and disassembled, the tilted side is clamped by the snap-in slot, so that the snap-in block can more easily fit into the snap-in slot to complete the snap-in operation.

[0012] Optionally, the clamping groove is wavy, and the rotating surface and the clamping surface are arranged at intervals.

[0013] By adopting the above technical solution, the wavy clamping groove enables the clamping block to be clamped with the clamping groove at any rotation position. When the connection between the first thread and the second thread changes, the clamping groove can also be clamped with the clamping block to ensure the anti-dismantling effect.

[0014] Optionally, there are two clamping blocks, which are arranged oppositely on the side walls of the knob seat.

[0015] By adopting the above technical solution, the two clamping blocks can improve the clamping effect, thereby ensuring the anti-disassembly performance of the knob structure.

[0016] Optionally, the knob seat further has a pressing groove, and the pressing groove corresponds to a clamping block provided on the side wall of the knob seat.

[0017] By adopting the above technical solution, the pressing groove can sink into the surface of the knob seat after the clamping block is pressed, so that the clamping block does not occupy too much space when rotating, ensuring the normal rotation of the knob structure.

[0018] Optionally, the first thread is located at an end portion of the clamping block close to the knob seat.

[0019] By adopting the above technical solution, the clamping block is arranged below the first thread, and the corresponding clamping groove is arranged below the second thread, so that when the knob seat and the knob cover are rotated and connected, the first thread and the second thread are connected first, and at the end of the rotational connection, the clamping block is connected to the clamping groove, thereby making the connection process faster and more convenient.

[0020] Optionally, the outer wall of the knob cover is cylindrical.

[0021] By adopting the above technical solution, the outer wall of the knob cover is cylindrical, so that the knob cover has a better grip and aesthetics, is easy for users to operate, and has a simple and elegant appearance.

[0022] Optionally, the clamping block is provided with a mounting edge, which is provided at an edge of the clamping block close to the end of the knob seat, so that the clamping block can be conveniently clamped into the clamping slot.

[0023] By adopting the above technical solution, since the snap-in block protrudes from the surface of the knob seat and needs to be snapped into the snap-in groove during installation, the provision of the mounting edge allows the snap-in block to snap into the snap-in groove when the knob seat and the knob cover rotate relative to each other, thus avoiding the need to manually snap the snap-in block in, and facilitating the use of the knob structure.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The rotating surface of the snap-in groove presses the snap-in block when the knob base and knob cover are rotated together, allowing the rotational connection to proceed normally. When the knob base and knob cover are rotated in the opposite direction to separate, the snap-in block is resisted by the snap-in surface of the snap-in groove, preventing the knob base from rotating in the opposite direction, thereby achieving the purpose of anti-tampering. This knob structure automatically forms a snap-in anti-tampering structure after the knob base and knob cover are rotated together. It is easy to operate and the fully locked state is difficult to separate even if separated manually, which improves the applicability of the anti-tampering structure.

[0026] 2. The snap-in block is tilted from one side, so that when the knob structure is rotated to connect, the tilted side can be pressed by the snap-in slot. When the knob structure is rotated to separate, the tilted side is engaged by the snap-in slot, making it easier for the snap-in block to fit into the snap-in slot to complete the snap-in operation.

[0027] 3. Since the snap-in block protrudes from the surface of the knob seat and needs to be snapped into the snap-in groove during the installation process, the installation edge is provided so that the snap-in block can be snapped into the snap-in groove when the knob seat and the knob cover rotate relative to each other; the need to manually snap the snap-in block is avoided, making the use of the knob structure more convenient.

[0033] The present application is further described in detail below with reference to the accompanying drawings.

[0034] A tamper-proof threaded knob structure, referring to Figure 1 , comprising a knob base 1 and a knob cover 2, wherein both the knob base 1 and the knob cover 2 are cylindrical structures, and the knob cover 2 can be sleeved on the outer side of the knob base 1. The outer wall of the knob base 1 is provided with a first thread 11 and a clamping block 12, and the inner wall of the knob cover 2 is provided with a second thread 21 and a clamping groove 22. The second thread 21 is matched with the first thread 11. By rotating the knob cover 2 and the knob base 1 relative to each other, the first thread 11 and the second thread 21 are connected, thereby connecting the knob base 1 and the knob cover 2.

[0035] Reference Figure 2 There are two clamping blocks 12, which are relatively arranged below the first thread 11. The clamping blocks 12 protrude from the surface of the knob seat 1, wherein one side of the clamping block 12 is elastically connected to the knob seat 1, and the other side is tilted from the surface of the knob seat 1, so that the clamping block 12 forms a certain angle with the surface of the knob seat 1, and is connected to the surface of the knob seat 1 in a manner similar to a tangent. When the knob seat 1 and the knob cover 2 are rotated in a connected manner, the tilted end of the clamping block 12 will be pressed down by the clamping groove 22, so that the rotational connection between the knob seat 1 and the knob cover 2 is not hindered. A pressing groove 13 is provided on the surface of the knob seat 1 corresponding to the clamping block 12. After being pressed, the clamping block 12 can sink into the pressing groove 13, so that the clamping groove 22 can be closer to the clamping block 12, so that when the clamping is formed, the clamping structure can also be more stable.

[0036] Reference Figure 2 and Figure 4The snap-fitting groove 22 is aligned with the snap-fitting block 12. The snap-fitting groove 22 is a wave-shaped structure and is located on the outer side of the inner side wall of the knob cover 2, that is, below the second thread 21. The snap-fitting groove 22 has a rotating surface 23 and a snap-fitting surface 24. The rotating surface 23 can press the snap-fitting block 12 when the knob base 1 and the knob cover 2 are rotationally connected, thereby allowing the first thread 11 and the second thread 21 to rotate and connect normally. When the knob base 1 and the knob cover 2 are rotationally connected, and the snap-fitting block 12 is in an area where the rotating surface 23 cannot press, the snap-fitting block 12 will tilt up, thereby forming a snap-fitting connection with the snap-fitting surface 24, so that the knob base 1 and the knob cover 2 cannot rotate in the opposite direction, thereby achieving the purpose of preventing disassembly.

[0037] Reference Figure 3 and Figure 4 The upward edge of the clamping block 12 is also provided with a mounting edge 14, and the mounting edge 14 is an inclined slope. The clamping block 12 and the clamping groove 22 are respectively located below the first thread 11 and the second thread 21. During the rotation connection process, the clamping block 12 needs to be clamped into the clamping groove 22 from the bottom. Since the clamping block 12 will protrude from the surface of the clamping groove 22 due to elasticity, the mounting edge 14 is provided, so that the clamping block 12 can be squeezed into the clamping groove 22 as the knob seat 1 rotates and rises, making the installation of the knob structure more convenient.

[0038] The implementation principle of the embodiment of the present application is as follows: the first thread 11 and the second thread 21 enable the knob base 1 and the knob cover 2 to be tightly connected, while the snap-in block 12 and the snap-in groove 22 only need to prevent the knob base 1 and the knob cover 2 from rotating in the opposite direction to achieve anti-dismantling. The snap-in block 12 and the snap-in groove 22 can achieve unidirectional snap-in. When the knob base 1 and the knob cover 2 are connected and rotated, the snap-in block 12 will not form a snap-in with the snap-in groove 22. When the knob base 1 and the knob cover 2 rotate in the opposite direction, the snap-in block 12 and the snap-in groove 22 form a snap-in to prevent directional rotation. The anti-dismantling threaded knob structure provided in this embodiment increases the anti-dismantling performance while ensuring convenient operation. It has a simple structure and is easy to produce and maintain. This design enhances the safety of the device while improving the user experience, and solves the problem of low applicability of existing anti-dismantling structures.

[0039] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
