[0002] The knobs in the relevant technologies are prone to falling off after long-term use. The main reason is that most knobs do not have an anti-detachment structure. Even if there is an anti-detachment structure, it will cause trouble for users due to cost and difficulty in disassembly and assembly. Therefore, there is still room for improvement in the anti-detachment structure of knobs. Utility Model Content

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0039] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application discloses a knob structure, including a knob component 100, a mounting component 200, a fixing component 300, and an anti-detachment component 400.
[0040] The knob component 100 is rotatably mounted on the mounting assembly 200; the anti-detachment component 400 acts on the knob component 100; the fixing member 300 is used to limit the anti-detachment component 400 so that the anti-detachment component 400 can limit the knob component 100 in a preset position.
[0041] In the embodiments of this application, the knob component 100 is mounted on the mounting assembly 200, and the position of the anti-detachment component 400 is fixed by the fastener 300, so that the anti-detachment component 400 can act on the knob component 100 and achieve the anti-detachment effect. This structure is not only easy to assemble and disassemble and has low cost, but also has excellent anti-detachment effect.
[0042] It is understood that the mounting component 200 serves as a mounting base for the rotatable setting of the knob component 100, enabling the knob structure of this embodiment to perform common functions such as adjustment and control when mounted on a device or apparatus. Traditional knobs do not have an anti-detachment structure, allowing them to be easily unscrewed. In some embodiments of this application, an anti-detachment component 400 acts on the knob component 100. The anti-detachment component 400, without affecting the rotation of the knob component 100, limits the movement of the knob component 100 in the detachment direction, making it less prone to detachment even under long-term, repeated use. Furthermore, to ensure reliable installation of the anti-detachment component 400 and maintain the anti-detachment effect on the knob component 100, the position of the anti-detachment component 400 is fixed by the fixing component 300. Since the fixing component 300 is used to fix the position of the anti-detachment component 400, the anti-detachment component 400 continues to play a limiting role even when the knob component 100 is rotating normally, thereby limiting the knob component 100 to the installed position. Even after repeated use or multiple rotations, the knob component 100 is not easy to come out of the installed position, thus achieving the anti-detachment effect.
[0043] In some embodiments, the mounting assembly 200 has structures including, but not limited to, shaft-like components, mounting bosses, or mounting holes 403, allowing the knob component 100 to be rotatably mounted on the mounting assembly 200. In some embodiments, the anti-detachment component 400, without affecting the rotation of the knob component 100, may be configured to include, but not limited to, pins, baffles, or anti-retraction structures, thereby restricting the knob component 100 from disengaging in the axial direction. In some embodiments, the fixing member 300 may be provided and fixed to the anti-detachment component 400 by means including, but not limited to, limiting abutment, threaded connection, snap-fit connection, welding, etc. Further, in some embodiments, the fixing member 300 may be provided on the mounting assembly 200, or on a device or apparatus using the knob structure of the present application embodiment, or on a structure or device housing in the external environment, thereby fixing the position of the anti-detachment component 400 by the fixing member 300. Under the premise that the anti-detachment component 400 is reliably limited, the anti-detachment component 400 can have a good anti-detachment effect.
[0044] The following will combine Figures 1 to 4 The knob structure disclosed in the embodiments of this application will be explained and described in detail.
[0045] It should be understood that for the anti-detachment component 400 to have a better anti-detachment effect, the structural design of the limiting anti-detachment component 400 is the key to achieving the above functions. Since the knob component 100 may cause the anti-detachment component 400 to rotate slightly or have a tendency to rotate when rotated, it may affect the limiting effect of the fixing member 300 on the anti-detachment baffle. If the fixing member 300 comes out, it may further cause the knob component 100 to be unscrewed.
[0046] In this regard, in some embodiments of this application, reference is made to Figure 2 and Figure 3 A first limiting structure is provided between the mounting component 200 and the anti-detachment component 400. The first limiting structure is used to restrict the movement of the anti-detachment component 400 along the rotation direction of the knob component 100.
[0047] It is understood that since the mounting component 200 is fixedly mounted as a base or installed on a device or apparatus using the knob structure of this application embodiment, a first limiting structure is provided between the anti-detachment component 400 and the mounting component 200. By using the first limiting structure to restrict the rotation of the anti-detachment component 400, the anti-detachment component 400 can be smoothly installed in place along the axial direction or other directions of the knob component 100 without slight rotation due to the rotation of the knob component 100. Consequently, the rotation of the knob component 100 is less likely to affect the fixing member 300, so that the limiting effect of the fixing member 300 on the anti-detachment component 400 can be sustained, making the knob structure of this application embodiment better at preventing detachment.
[0048] In some embodiments, the first limiting structure may be configured as including, but not limited to, structures that cooperate between a stop groove and a stop member, keys, locating pins, ratchet structures, one-way tooth structures, and other commonly used structures for limiting rotation.
[0049] In some embodiments of this application, reference is made to Figure 2 and Figure 3 The first limiting structure includes an anti-detachment groove 510 and an anti-detachment boss 520; the mounting component 200 has an anti-detachment groove 510, and the anti-detachment component 400 has an anti-detachment boss 520; or the mounting component 200 has an anti-detachment boss 520, and the anti-detachment component 400 has an anti-detachment groove 510; the anti-detachment boss 520 is embedded in the anti-detachment groove 510, and the fixing member 300 limits the anti-detachment component 400 after the anti-detachment boss 520 is embedded in the anti-detachment groove 510.
[0050] It is understandable that the anti-detachment groove 510 is used to accommodate the anti-detachment boss 520. Utilizing the structural shape of the anti-detachment boss 520 itself, the anti-detachment component 400 can be installed based on the cooperation between the anti-detachment boss 520 and the anti-detachment groove 510. The assembly 200 is limited in the rotation direction along the knob component 100. Thus, after the anti-detachment component 400 is limited by the fixing member 300, the fixing member 300 will not be affected by the rotation of the knob component 100.
[0051] Specifically, the anti-detachment boss 520 protrudes along the axial direction of the knob component 100. During installation, the anti-detachment component 400 approaches the mounting assembly 200 along the axial direction of the knob component 100 and the anti-detachment boss 520 is embedded in the anti-detachment groove 510. At this time, the anti-detachment component 400 is initially pre-positioned. Then, the anti-detachment component 400 is limited by the fixing member 300. Finally, after fixing the fixing member 300, the installation is completed.
[0052] It should be understood that when the mounting component 200 has an anti-detachment groove 510, the anti-detachment component 400 is correspondingly provided with an anti-detachment boss 520. Conversely, when the mounting component 200 is provided with an anti-detachment boss 520, the mounting component 200 is provided with an anti-detachment groove 510. Both of these configurations enable the first limiting structure to restrict the rotation of the anti-detachment component 400.
[0053] In some embodiments of this application, reference is made to Figure 1The mounting component 200 has a threaded hole 201, and the anti-detachment component 400 has a mounting hole 403. The fastener 300 passes through the mounting hole 403 and is installed in the threaded hole 201. It is understood that the fastener 300 in this embodiment is provided on the mounting component 200, making the overall structure more compact. The threaded connection further improves the convenience of disassembly and assembly. Since the rotation of the knob component 100 cannot affect the fastener 300 due to the first limiting structure, the fastener 300 can be securely and reliably installed in the threaded hole 201.
[0054] In some embodiments, since the fastener 300 is installed in the threaded hole 201 through the mounting hole 403, the mounting hole 403 can be a commonly used hole structure such as a threaded hole 201 or a smooth hole without affecting the limiting effect on the anti-detachment component 400.
[0055] In some embodiments, based on the fastener 300 being installed in the threaded hole 201, common components such as washers and nuts can be used to ensure the installation effect of the fastener 300, which will not be further described here.
[0056] In one specific embodiment, refer to Figure 1 The anti-detachment component 400 is an anti-detachment baffle, which has a limiting surface 401 and a mounting surface 402 opposite to the limiting surface 401. The limiting surface 401 is used to abut against the knob component 100, and the fixing member 300 passes through the limiting surface 401 from the mounting surface 402 and is disposed on the mounting assembly 200. It can be understood that the knob structure of this embodiment of the application acts on the knob component 100 through the limiting surface 401 of the anti-detachment baffle, so that the movement of the knob component 100 in the axial direction of the detachment is limited, and the position of the anti-detachment baffle is limited by the fixing member 300, thereby achieving a good anti-detachment effect.
[0057] In this embodiment, the fastener 300 passes through the mounting surface 402 and is installed on the mounting assembly 200 or equipment via its end. After installation, the end of the fastener 300 abuts against the mounting surface 402, thereby limiting the anti-detachment plate. In some embodiments, pre-tightening elements such as threaded pre-tightening elements and elastic pre-tightening elements that can provide pre-tightening force can also be provided to act on at least one of the fastener 300 or the anti-detachment plate, thereby improving the limiting effect on the anti-detachment plate.
[0058] In some embodiments of this application, reference is made to Figure 1The mounting assembly 200 includes a connector 210 and a mounting plate assembly. The connector 210 passes through the mounting plate assembly so that its end is used to connect to the knob component 100. It is understood that by using the connector 210 as a mounting base for the rotatable knob component 100, and by using the mounting plate assembly for its fixed installation and as a mounting base, the knob component 100, the anti-detachment component 400, and the fixing component 300 can all be smoothly installed.
[0059] In some embodiments, both the fixing member 300 and the connecting member 210 are screws, thereby facilitating the installation of the various components of the knob structure of this application embodiment. In other embodiments, at least one of the fixing member 300 or the connecting member 210 may also be configured as commonly used components such as pins and bolts, but not limited to them.
[0060] It should be understood that, since the knob component 100 may cause the connector 210 to rotate slightly or tend to rotate when rotated, it may affect the connection effect of the knob component 100. In this regard, in some embodiments of this application, a second limiting structure 600 is provided between the connector 210 and the mounting plate assembly, the second limiting structure 600 being used to limit the connector 210 circumferentially.
[0061] It is understood that since the mounting plate assembly is fixedly installed as a base or installed on the device or apparatus using the knob structure of this application embodiment, a second limiting structure 600 is provided between the mounting plate assembly and the connector 210. By using the second limiting structure 600 to restrict the rotation of the connector 210, the connector 210 can be smoothly installed in place along the axial direction or other directions of the knob component 100 without slight rotation due to the rotation of the knob component 100. This ensures the stable installation of the knob component 100 to maintain the limiting effect of the anti-detachment component 400, making the knob structure of this application embodiment better at preventing detachment.
[0062] In some embodiments, the second limiting structure 600 may be configured as a structure that includes, but is not limited to, a structure in which a stop groove and a stop member cooperate, a key, a locating pin, a ratchet structure, a one-way tooth structure, or other commonly used structures for limiting rotation.
[0063] In some embodiments of this application, the connector 210 is used to mount the knob component 100. To reduce the impact of the knob component 100 rotating on the connector 210 and to prevent the connector 210 from dislodging, refer to... Figure 2The second limiting structure 600 includes a limiting groove and a limiting boss. When the limiting groove is formed on the mounting plate assembly, the limiting boss is provided on the connector 210; when the limiting groove is formed on the connector 210, the limiting boss is provided on the mounting plate assembly. By embedding the limiting boss into the limiting groove, the circumferential rotation of the connector 210 is limited by the fixedly mounted mounting plate assembly.
[0064] Understandably, the limiting groove is used to accommodate the limiting boss. By utilizing the structural shape of the limiting boss itself, the connector 210 can be limited by the mounting plate assembly in the rotation direction along the knob component 100 based on the cooperation between the limiting boss and the limiting groove, thereby ensuring that the connector 210 is not affected by the rotation of the knob component 100.
[0065] Specifically, the limiting boss protrudes along the axial direction of the connector 210 on the bottom surface of the end of the connector 210. During installation, the connector 210 is installed axially on the mounting plate assembly and the limiting boss is embedded in the limiting groove.
[0066] To make the knob structure of this application embodiment easier to assemble and disassemble, reference is made to... Figure 1 and Figure 4 In some embodiments of this application, the mounting plate assembly includes a first clamping plate 220 and a second clamping plate 230, with a connector 210 passing through the first clamping plate 220 and the second clamping plate 230, such that the end of the connector 210 is used to connect to the knob component 100. It is understood that by using the connector 210 as a mounting base for the rotatable mounting of the knob component 100, and by having the connector 210 pass through the first clamping plate 220 and the second clamping plate 230, the knob component 100 of this embodiment can be reliably mounted using at least one of the first clamping plate 220 or the second clamping plate 230. Furthermore, by dividing the mounting plate assembly into two structural components, the first clamping plate 220 and the second clamping plate 230, installation flexibility is also improved.
[0067] Furthermore, referring to Figure 1 The end of the connector 210 is connected to the knob component 100 via a threaded structure. When the knob component 100 is inserted along the threaded structure, it can drive the first clamping plate 220 and the second clamping plate 230 to move closer together, and when it is in place, the first clamping plate 220 and the second clamping plate 230 are tightly pressed against each other. It can be understood that the relative interval between the first clamping plate 220 and the second clamping plate 230 provides feedback on whether the knob component 100 is installed in place. When the first clamping plate 220 and the second clamping plate 230 are tightly pressed against each other, it means that the knob component 100 is installed in place. At this time, the anti-detachment component 400 is set to prevent the knob component 100 from coming off. The compact structure ensures a more stable and better limiting effect.
[0068] In some embodiments of this application, reference is made to Figure 1The knob component 100 has a receiving groove 110, and the fixing member 300 and the anti-detachment member 400 are located in the receiving groove 110. By setting both the fixing member 300 and the anti-detachment member 400 in the receiving groove 110, the space utilization of the embodiment of this application is more reasonable and the layout is more compact.
[0069] Furthermore, referring to Figure 1 The knob structure also includes a knob cover 700, which is closable on the knob component 100 and used to close the receiving groove 110. By closing the receiving groove 110 with the knob cover 700, the fixing member 300 and the anti-detachment member 400 disposed inside the knob component 100 can be protected. At least one of the fixing member 300 or the anti-detachment member 400 can be replaced by opening the knob cover 700, which improves the convenience of use.
[0070] The knob structure of this application embodiment is described in detail below with a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.
[0071] See Figures 1 to 4 As shown, the knob structure of this embodiment includes a knob component 100, a first screw, a second screw, and an anti-dislodgement plate.
[0072] The knob component 100 has threads that mate with the second screw. The end of the second screw has an anti-disengagement groove 510 and a threaded hole 201. The diameter of the anti-disengagement plate is larger than that of the second screw, and the anti-disengagement plate has an anti-disengagement boss 520 and a through hole. During assembly, the knob component 100 is first installed on the second screw, and then the anti-disengagement boss 520 on the anti-disengagement plate is inserted into the anti-disengagement groove 510 at the end of the second screw, and then secured with the first screw. When the knob component 100 is rotated outward to the point of almost falling off, the knob component 100 will press against the anti-disengagement plate, thereby preventing the knob component 100 from continuing to rotate outward and thus preventing the knob component 100 from being screwed off. The anti-detachment protrusion 520 on the anti-detachment plate is locked in the anti-detachment groove 510 of the second screw, so that the anti-detachment plate cannot rotate with the knob component 100, thus preventing the knob component 100 from driving the anti-detachment plate to rotate, thereby driving the first screw to rotate and causing the first screw to loosen, ensuring the reliability of anti-detachment.
[0073] Preferably, the assembly also includes a first clamping plate 220 and a second clamping plate 230. Both the first clamping plate 220 and the second clamping plate 230 have holes for the second screw to pass through. Furthermore, the head of the second screw is a flat, round head with a square neck. Correspondingly, the hole in the first clamping plate 220 has a square groove, and the square neck of the second screw is engaged in the square groove of the first clamping plate 220, preventing it from rotating relative to the first screw. In addition, when the knob component 100 rotates inward, the first clamping plate 220 and the second clamping plate 230 are clamped together by the action of the knob component 100 and the head of the second screw. When the knob component 100 rotates outward, the first clamping plate 220 and the second clamping plate 230 are released. Finally, a knob cover 700 is included to make the overall appearance neat and aesthetically pleasing.
[0074] The second aspect of this application discloses a device including: a knob structure according to the first aspect of this application.
[0075] It is easy to understand that the device in the second aspect embodiment of this application has the same technical effects as the knob structure in the first aspect embodiment, and therefore will not be described again.
