[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figures 1 to 4 As shown, an embodiment of the present invention provides a clamping mechanism. The clamping mechanism includes a fixing assembly and a pressing assembly. The fixing assembly has a holding end 11; the pressing assembly includes an operating member 21 and a pressing member 22 connected to the operating member 21. The pressing assembly is rotatably mounted on the fixing assembly. By rotating the operating member 21, the pressing member 22 can switch between a clamping position close to the holding end 11 to hold the clamped member, and a release position away from the holding end 11 to release the clamped member.

[0031] When the second frame 1 needs to be adjusted on the first frame 1, the operating member 21 is rotated in the opposite direction to move the pressing member 22 away from the abutting end 11, and the clamping mechanism can release the first frame 1, thereby facilitating the movement of the clamping mechanism, so as to facilitate the movement of the second frame, and then the operating member 21 is rotated again to make the pressing member 22 close to the abutting end 11 and abut against the first frame 1, so that the second frame is fixed to the first frame 1. Therefore, the clamping mechanism of the present invention only needs to rotate the operating member 21 to lock the second frame 1 on the first frame 1 through the clamping mechanism or release the clamping mechanism to release the first frame 1, thereby facilitating the adjustment of the relative position between the second frame and the first frame 1, thereby achieving the effect of simple operation.

[0032] like Figure 3 As shown, in the embodiment of the present invention, there is a pivot point between the clamping assembly and the fixing assembly, and the clamping member 22 is provided with a clamping surface at one end facing the abutting end 11, at least part of the clamping surface is an arcuate surface, and the arcuate surface protrudes in the direction away from the pivot point.

[0033] Through the above arrangement, the arcuate surface can play a guiding role, facilitating the switching of the pressing member 22 between the clamping position and the releasing position, thereby improving the convenience of operation.

[0034] like Figure 3 As shown, in the embodiment of the present invention, the pressing surface includes a plane 221 and an arc-shaped slope 222 connected to the plane 221 . The plane 221 is located on the high side of the arc-shaped slope 222 , and the plane is used to press against the part to be clamped.

[0035] Through the above arrangement, the arc-shaped slope 222 plays a guiding role. Figure 3The pressing assembly is rotated counterclockwise, and the lower side of the arc-shaped slope 222 first faces the first frame 1, and then the pressing assembly is continued to be rotated, and the distance between the arc-shaped slope 222 and the first frame 1 gradually decreases until the high side of the arc-shaped slope 222 and the flat surface 221 successively abut against the first frame 1, so that it is easy to rotate the pressing assembly and to switch the pressing member 22 from the release position to the clamping position; Figure 3 When the clamping assembly is rotated clockwise, the high sides of the plane 221 and the arc-shaped slope 222 are separated from the first frame 1 in turn, and the low side of the arc-shaped slope 222 can avoid the first frame 1 to prevent the first frame 1 from hindering the continued rotation of the clamping surface, thereby facilitating the rotation of the clamping assembly and facilitating the switching of the clamping member 22 from the clamping position to the release position.

[0036] It should be noted that in the embodiment of the present invention, the low side of the curved slope 222 is closer to the support shaft 12 than the high side of the curved slope 222, that is, the end of the curved slope 222 away from the support shaft 12 is the high side, and the end of the curved slope 222 close to the support shaft 12 is the low side, that is, the end of the curved slope 222 away from the supporting end 11 is the low side, and the end of the curved slope 222 close to the supporting end 11 is the high side.

[0037] In one embodiment, the entire pressing surface may be an arc-shaped surface, so that when the pressing member 22 is in the clamping position, the pressing surface is in linear contact with the first frame 1 .

[0038] like Figure 3 As shown, in the embodiment of the present invention, a support shaft 12 is provided within the fixing assembly, and a pivot hole 23 is provided on the operating member 21. The support shaft 12 rotatably engages with the pivot hole 23. Thus, the operating member 21 can be rotated relative to the fixing assembly, thereby causing the pressing member 22 to rotate relative to the fixing assembly, so that the pressing surface can move closer to or further away from the first frame 1.

[0039] In one embodiment, a pivot hole 23 may also be provided on the pressing member 22 .

[0040] like Figure 3 and Figure 4 As shown, in an embodiment of the present invention, at least one first limiting member 13 and at least one second limiting member 18 are provided in the fixing assembly, the first limiting member 13 is provided with a first groove 14, and the second limiting member 18 is provided with a second groove 19. The first limiting member 13 and the second limiting member 18 are respectively located on the radial sides of the support shaft 12, and the first groove 14 and the second groove 19 are both limited and matched with the support shaft 12.

[0041] Through the above arrangement, the first limiting member 13 and the second limiting member 18 can be used to limit and fix the support shaft 12, thereby fixing the support shaft 12 in the fixing assembly.

[0042] Preferably, in an embodiment of the present invention, there is one first limiting member 13 and one second limiting member 18, and the first limiting member 13 and the second limiting member 18 are arranged at intervals along the axial direction of the support shaft 12 to support and limit the support shaft 12, thereby fixing the support shaft 12 in the fixing assembly; wherein, the first limiting member 13 is fixedly connected to the cover plate 17, and the second limiting member 18 is fixedly connected to the fixing seat 10.

[0043] In one embodiment, there are multiple first limiting members 13 and multiple second limiting members 18 , and the first limiting members 13 and the second limiting members 18 are alternately arranged in the axial direction of the support shaft 12 .

[0044] In one embodiment, there are multiple first limiting members 13 and multiple second limiting members 18. Multiple first limiting members 13 are arranged at intervals along the axial direction of the support shaft 12, and multiple second limiting members 18 are arranged at intervals along the axial direction of the support shaft 12. The first limiting members 13 and the second limiting members 18 are arranged correspondingly so that the first groove 14 and the first groove 14 are spliced ​​to form a limiting hole for limiting the support shaft 12.

[0045] like Figure 6 As shown, in an embodiment of the present invention, the clamping mechanism also includes an elastic member 50, the first end of the elastic member 50 is connected to the fixing assembly, and the second end of the elastic member 50 is connected to the clamping assembly. The elastic member 50 is used to provide an elastic force to restore the clamping assembly to a released position.

[0046] With the above settings, Figure 6 In the process, the operating member 21 is rotated counterclockwise to overcome the elastic force of the elastic member 50, so that the pressing surface abuts against the first frame 1, so as to clamp the clamping mechanism on the first frame 1. When it is necessary to adjust the position of the second frame on the clamping mechanism relative to the first frame 1, the operating member can be rotated clockwise to switch the pressing surface from the state of abutting against the first frame 1 to the state of releasing the first frame 1. Under the action of the elastic member 50, the pressing member 22 can return to the released position, thereby making the operation simpler and facilitating the adjustment of the position of the second frame relative to the first frame 1.

[0047] Preferably, in the embodiment of the present invention, the elastic member 50 is a spring.

[0048] like Figure 6 As shown, in the embodiment of the present invention, the operating member 21 is pivotally connected to the fixed assembly, the elastic member 50 is used to provide a pulling force to the operating member 21, and the pivot point between the operating member 21 and the fixed assembly is located between the second end of the elastic member 50 and the pressing member 22. Figure 6In the process, the operating member 21 is rotated counterclockwise to stretch the elastic member 50 so that the pressing surface abuts against the first frame 1 to clamp the clamping mechanism on the first frame 1. When it is necessary to adjust the position of the second frame on the clamping mechanism relative to the first frame 1, the operating member can be rotated clockwise to switch the pressing surface from abutting against the first frame 1 to releasing the first frame 1. Under the action of the pulling force of the elastic member 50, the pressing member 22 can return to the released position, thereby making the operation simpler and facilitating the adjustment of the position of the second frame relative to the first frame 1.

[0049] In one embodiment, the second end of the elastic member 50 may be located between the pivot point between the operating member 21 and the fixing assembly and the pressing member 22 , and the elastic member 50 is in a compressed state.

[0050] like Figure 1 、 Figure 3 and Figure 5 As shown, in an embodiment of the present invention, the fixing assembly includes a fixing seat 10, a cover plate 17 and a supporting member, the cover plate 17 is connected to the fixing seat 10, the supporting member is connected to the side of the cover plate 17 facing away from the fixing seat 10, and a receiving space for accommodating the part to be clamped is formed between the supporting member and the cover plate 17, wherein the supporting member forms a supporting end 11.

[0051] Through the above arrangement, the part to be clamped (part of the first frame) can be placed in the accommodating space. By moving the clamping mechanism, the position of the second frame on the clamping mechanism relative to the first frame 1 can be adjusted. Then, the operating member 21 is rotated to make the pressing member 22 abut against the first frame 1 to fix the second frame on the first frame 1.

[0052] Preferably, in the embodiment of the present invention, the cover plate 17 and the fixing seat 10 are connected by screws.

[0053] Preferably, in an embodiment of the present invention, the first end of the elastic member is connected to the cover plate 17 , and the second end of the elastic member is connected to the pressing assembly.

[0054] like Figure 3 and Figure 7 As shown, in the embodiment of the present invention, the pressing member 22 is installed in the fixing seat 10, and the cover plate 17 is provided with an avoidance hole 15 connected to the interior of the fixing seat 10, so that the pressing member 22 can extend out of or be retracted into the fixing seat 10 through the avoidance hole 15.

[0055] With the above arrangement, by rotating the operating member 21, the pressing member 22 can extend out of the fixing seat 10 through the avoidance hole 15 and into the accommodating space, so as to abut the first frame 1 against the abutting member; by reversing the operating member 21, the pressing member 22 can be retracted from the accommodating space into the fixing seat 10 through the avoidance hole 15. In this way, when adjusting the position of the clamping mechanism relative to the first frame 1, the problem of interference between the pressing member 22 and the first frame 1 and resulting in poor movement can be avoided.

[0056] like Figure 3 As shown, in the embodiment of the present invention, the operating member 21 includes an operating section 211 and a connecting section 212 connected to each other. The operating section 211 and the connecting section 212 are arranged at an angle. The connecting section 212 is located in the fixing seat 10 and is connected to the pressing member 22. The operating section 211 can extend out of the fixing seat 10. In this way, the pressing assembly can be rotated by rotating the operating section 211, which is convenient for the operator to operate.

[0057] Preferably, in the embodiment of the present invention, the operating section 211 , the connecting section 212 and the pressing member 22 are integrally formed, which facilitates processing.

[0058] like Figures 5 to 9 As shown, an embodiment of the present invention provides a monitor stand. The monitor stand comprises a first frame 1, a second frame, and a clamping mechanism 2 described below. The second frame is connected to a fixing base 10 of a fixing assembly. The first frame 1 has a limiting flange 3 that slidably engages with a receiving space of the fixing assembly, forming a member to be clamped.

[0059] Through the above arrangement, the operating member 21 is rotated to release the limiting flange 3 by the pressing member 22. The position of the second frame relative to the first frame 1 can be adjusted by moving the clamping mechanism 2 to slide the limiting flange 3 in the accommodating space. Then, the operating member 21 is rotated to press the limiting flange 3 by the pressing member 22 to fix the clamping mechanism 2 on the first frame 1, thereby fixing the second frame relative to the first frame 1.

[0060] The above-mentioned display bracket has all the advantages of the above-mentioned clamping mechanism 2, which will not be described in detail here.

[0061] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the second frame is connected to the fixed seat, and part of the first frame is placed between the pressing member and the abutting end, and the operating member is rotated so that the pressing member is close to the abutting end and abuts against the first frame, so that the second frame can be fixed to the first frame; when it is necessary to adjust the position of the second frame on the first frame, the operating member can be rotated in the opposite direction to make the pressing member move away from the abutting end, and the clamping mechanism can release the first frame, thereby facilitating the movement of the clamping mechanism to facilitate the movement of the second frame, and then the operating member is rotated again to make the pressing member close to the abutting end and abut against the first frame, so that the second frame is fixed to the first frame. Therefore, the clamping mechanism of the present invention only needs to rotate the operating member to lock the second frame on the first frame through the clamping mechanism or release the clamping mechanism to release the first frame, thereby facilitating the adjustment of the relative position between the second frame and the first frame, thereby achieving the effect of simple operation.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
