[0002] The interface size of the existing quick-release devices for photography is fixed. For example, in the prior art, the patent with publication number CN216743546U mentions a magnetic suction structure, which has the following problems: each brand has its own quick-release plate with an Arca interface, but the size of the quick-release plates processed by each manufacturer is different, and there is no unified size requirement, and thus there is a lack of an installation mechanism that is compatible with quick-release plates of various sizes for quick assembly. Utility Model Content

[0003] The utility model aims to provide a mounting mechanism for mounting a quick-release plate, which can meet the requirements of mounting quick-release plates of different sizes in the mounting mechanism by adjusting the size of the opening.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions.

[0005] The mounting mechanism for mounting a quick-release plate comprises a lower cover, an upper cover forming a cavity, and a quick-release plate, wherein an opening is provided at the upper portion of the cavity, one end of the opening forms a fixed end, and the other end is provided with a movable part, and the movable part moves horizontally along the cavity to adjust the size of the opening, thereby adapting to the disassembly and assembly of quick-release plates of different sizes;

[0006] The upper cover is fixed on the lower cover, and a locking mechanism for locking or unlocking the quick-release plate is provided between the upper cover and the lower cover.

[0007] The cavity is integrally formed with a support portion close to the movable part and lower than the fixed end and close to the lower cover.

[0008] It also includes a driving mechanism located in the upper cover, which drives the movable part to move along the side of the cavity, so that the movable part and the fixed end form a clamping cavity with adjustable width.

[0009] The driving mechanism is an adjusting screw, and the supporting part is provided with a screw hole section matching the adjusting screw.

[0010] The screw rod of the adjusting screw passes through the movable part, and the screw head is clamped with the movable part.

[0011] One of the upper part of the movable part and the screw head of the adjusting screw forms a clamping groove, and the other forms a clamping block.

[0012] The locking mechanism comprises locking hooks respectively abutting against the upper cover and the lower cover, and the inner wall of the locking hook is provided with a locking surface matching the outer side of the quick-release plate.

[0013] It also includes a torsion spring assembled on the lower cover through the assembly part, and the torsion spring is respectively connected to the locking hook and the supporting part.

[0014] The locking hook is dovetail-shaped, and one side of the dovetail is provided with a locking surface and the other side abutting against the torsion spring forms a locking groove.

[0015] An inclined surface is formed on the outer side of the locking groove and abuts against the inclined surface of the inner wall of the fixing end.

[0016] The support portion extends downward to form a contact portion that is in contact with the torsion spring.

[0017] It also includes a rotating pin which passes through the torsion spring and drives the torsion spring to rotate. The rotating pin extends outward to form an unlocking knob which rotates along the lower cover.

[0018] The lower cover is provided with a bearing portion with an inverted T-shaped cross section, the supporting portion is partially inserted into the groove body of the inverted T-shaped side portion, and the inverted T-shaped top portion bears the supporting portion, and the inverted T-shaped bottom portion contacts the inner wall of the lower cover.

[0019] The beneficial effects of the utility model are as follows:

[0020] Firstly, in the utility model, movable adjustment is performed at the opening of the upper cover, and then when the size of the quick-release plate changes, the movable part can be adjusted to expand or reduce the opening to meet the installation of quick-release plates of different manufacturers and specifications, and has a wide range of applications.

[0021] Secondly, the supporting part in the utility model not only supports the quick-release plate, but also provides space and a range of motion for the assembly of movable parts, and at the same time provides a telescopic area for the locking and unlocking of the subsequent locking mechanism.

[0022] Again, in the utility model, a dovetail-shaped locking portion is selected, which is abutted at multiple locations. Before assembly, the support portion is pressed downward to squeeze the torsion spring.

DETAILED DESCRIPTION

[0031] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0032] Refer to the attached Figure 1-6 As shown, the installation mechanism for quick-release plate installation in the utility model specifically includes an upper cover 100, a lower cover 200, a locking mechanism 300, a movable part 400 and a quick-release plate 500; specifically, the upper cover 100 and the lower cover 200 form an assembly cavity for the quick-release plate 500, specifically, the lower cover 200 forms a base, and then the upper cover 100 is a through cavity, the bottom of which is fixed to the lower cover 200, and the upper part forms a fixed end 110 and a movable part 400, respectively, and then the movable part 400 is used to move horizontally along the cavity to adjust the size of the opening above the through cavity, thereby adapting to the disassembly and assembly of quick-release plates 500 of different sizes; in order to lock the assembled quick-release plate 500, the locking mechanism 300 is arranged between the upper cover 100 and the lower cover 200 for locking or unlocking the quick-release plate 500. By adding the movable part 400, the size of the present embodiment can be adjusted, so that quick-release plates of different sizes can enter the cavity for installation and locking.

[0033] In order to better assemble and fix the quick release plate, the cavity is integrally formed with a support portion 600 which is lower than the fixed end and close to the lower cover near the movable part 400. After the quick release plate is assembled, it is supported between the upper cover 100 and the lower cover 200 by the support portion 600.

[0034] With reference to the attached drawings, the following introduction will focus on the adjustment of the size of the opening.

[0035] In order to realize automatic opening size control, a driving mechanism is also included in the upper cover 100, which drives the movable member 400 to move along the side of the cavity, so that the movable member 400 and the fixed end 110 form a clamping cavity with adjustable width. The driving mechanism is used in conjunction with the movable member to form a clamping cavity with a length, thereby increasing the contact surface with the quick-release plate and ensuring stable assembly and installation.

[0036] Specifically, the driving mechanism is an adjusting screw 120, and the support portion 600 is provided with a screw hole section 610 matching the adjusting screw 120. The adjusting screw is low in cost, easy to obtain, and has a mature process. It is easy to operate during use and greatly meets user needs. The screw hole section has a certain length, which provides a basis for adjusting the length of the adjusting screw.

[0037] During the specific adjustment, the screw of the adjusting screw 120 passes through the movable member 400, and the screw head is clamped with the movable member 400. In this embodiment, the screw passes through the movable member, so that the screw head can drive the movable member to move horizontally left and right as the screw moves.

[0038] In order to better drive the movable part, the upper part of the movable part 400 and the screw head of the adjusting screw 120 form a slot and a block. In subsequent use, the slot and the block can be adjusted according to the specific structure and application scenario, as long as the screw head and the movable part are connected. In subsequent use, the slot and the block may not be in full contact, and a certain buffer may be provided to protect the screw head and the movable part.

[0039] In this embodiment, the size of the opening is adjusted as follows:

[0040] If the size of the quick-release plate of other brands is slightly larger, the locking mechanism 300 cannot be reset when the quick-release plate is installed. This is because the larger quick-release plate blocks the reset stroke of the locking mechanism 300. At this time, you only need to adjust the fine-tuning screw 120 to move the movable part 400 to the left, so that the relative position of the movable part 400 and the locking mechanism becomes larger, so that the larger quick-release plate can be locked;

[0041] On the contrary, if the size of the quick-release plate 500 is too small, and the upward travel of the locking mechanism 300 is limited, the quick-release plate of a smaller size cannot be locked after being assembled. In this case, it is necessary to fine-tune the adjustment screw 120 so that the movable part moves to the right, so that the relative position between the movable part 400 and the locking mechanism 300 becomes smaller, so that the quick-release plate of a smaller size can be locked.

[0042] The locking mechanism in this embodiment is specifically described as follows:

[0043] Refer to the attached Figure 1-6 As shown, the locking mechanism 300 in this embodiment includes a locking hook 310 respectively abutting against the upper cover 100 and the lower cover 200, and the inner wall of the locking hook 310 is provided with a locking surface 311 matching the outer side of the quick-release plate 500. During assembly, the locking hook 310 is respectively contacted and fixed with the upper cover 100 and the lower cover 200, and then the quick-release plate 500 is locked through the locking surface 311, thereby realizing rapid assembly.

[0044] In order to perform locking and resetting, two protrusions are added upwards to the lower cover 200 to form an assembly cavity, and then a torsion spring 320 is arranged in the assembly cavity. The torsion spring is fixedly connected to the rotating pin 350 concentrically, and then when the rotating pin 350 rotates, the torsion spring is driven to rotate. At this time, the torsion spring 320 connected to the locking hook 310 and the support part 600 respectively controls the up and down movement of the locking hook 310.

[0045] In order to facilitate user operation, an arc groove is set between the upper cover 100 and the lower cover 200, and then the rotating pin extends to form an unlocking knob 330 that rotates along the lower cover. The user directly rotates the unlocking knob 330 to make the torsion spring 320 drive the locking hook 310 to move up and down.

[0046] Specifically, in this embodiment, the locking hook 310 at the core of the locking mechanism 300 is dovetail-shaped. Figure 2 As shown, it forms a structure with three contact parts. Specifically, the first contact part is arranged toward the upper cover and the inner wall forms a locking surface locked with the quick-release plate 500. Then the second contact part is a contact surface 340 that is in contact with the torsion spring 320. Then the first contact part and the second contact part form a locking groove that locks the quick-release plate 500. At this time, in order to fully consider the contact with the upper cover, an inclined surface 312 is formed on the outer side of the locking groove to abut against the inclined surface of the inner wall of the fixed end 110.

[0047] In order to ensure the support of the support part 600, refer to the attached Figure 2 It can be seen that the lower cover 200 is provided with a bearing portion 210 with an inverted T-shaped cross section, the support portion 600 is partially inserted into the groove body of the inverted T-shaped side portion, and the inverted T-shaped top portion bears the support portion 600, and the inverted T-shaped bottom portion contacts the inner wall of the lower cover 200. In this embodiment, a gap is formed between the support portion 600 and the fixed end for inserting and removing the quick-release plate 500, and an inverted L-shaped structure is formed near the torsion spring to fix the torsion spring.

[0048] In this embodiment, two inclined plugs are integrally formed on one side of the quick-release plate 500, and the inclined plugs and the quick-release plate 500 form an expansion cavity. The two outer inclined surfaces of the expansion cavity are respectively in contact with the inclined surface formed on the inner wall of the movable part 400 and the locking surface on the locking hook for assembly.

[0049] When using the utility model, the quick installation process of the quick-release plate assembly is as follows:

[0050] First, use the adjusting screw 120 to adjust the size of the opening so that it is larger than the assembly width of the quick-release plate 500. At this time, the torsion spring is in a normal state. Then, when the quick-release plate 500 is installed into the upper and lower covers, pressure is applied so that the downward pressure of the quick-release plate 500 will be greater than the elastic force or compression spring force of the torsion spring 320 of the locking hook 310. The support part 600 moves downward, and synchronously drives the locking hook 310 to rotate clockwise downward. When the quick-release plate 500 is installed in place, the unlocking knob 330 is rotated so that the locking hook 310 rotates counterclockwise (reset) under the action of the torsion spring or compression spring force.

[0051] In this embodiment, a 1 / 4 threaded hole is provided on the quick release plate 500, to which a camera can be grafted; the locking hook 310 can rotate around the rotating pin, and the locking hook 310 is initially in a pop-up state due to a torsion spring or a compression spring, and thus the locking hook is the reason for realizing the quick installation of the quick release plate assembly, and the locking hook has a dovetail surface and contacts in multiple places, so the assembly is stable.

[0052] In this embodiment, the movable member 400 can move left and right inside the main body of the upper cover 100, and the movable member 400 can move to lock the quick-release plates of different sizes. The movable member 400 also has a dovetail surface on it, which cooperates with the dovetail inclined surface of the locking hook 310 to lock the quick-release plate 500.

[0053] In this embodiment, the installation and locking of quick-release plates 500 of different widths are achieved through a simple structure, achieving a wide compatibility effect. In this embodiment, a large supporting and fixing cavity is formed by using a support part, a movable part and a locking mechanism to match the assembly of the quick-release plate.
