Description

Technical Field

[0001] The utility model relates to the technical field of locking a shoulder strap in camera assembly, in particular to a shoulder strap locking mechanism and a camera quick-hanging mechanism containing the locking mechanism. Background Art

[0002] In the prior art, the straps are usually locked in the following ways:

[0003] The first one is to clamp and lock the two sides, for example, by cooperating with cams and hooks on both sides to clamp the strap in the middle. However, this method mainly increases the strap's capacity by replacing parts, and the operation is cumbersome.

[0004] The second method is to lock the straps by passing the dead point of the lever. This method has a small application range and is easy to unlock once it is overweight or the buckle is subjected to excessive force.

[0005] The third method is to continuously tighten the straps with screws. This method is performed by continuous clamping with external force, and the locking method is limited;

[0006] The above-mentioned methods have a small adaptability range. Once parts need to be replaced, cumbersome operations are required. When used for camera quick hang, the strap clamp is not secure. In certain circumstances, such as when subjected to high force, it is easy to unlock, causing safety issues. Utility Model Content

[0007] The purpose of the utility model is to provide a quick-release plate mounting seat and a camera quick-hanger, which acts on a trigger portion during assembly, thereby driving a sliding portion and a locking portion to move in different directions respectively, thereby occupying less space. In addition, this movement mode does not require adding other redundant structures in the assembly cavity to complete the disassembly and installation of the quick-release plate, making it more compatible with the quick-release plate and expanding its application range.

[0008] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions.

[0009] .The shoulder strap locking mechanism comprises a base, a cover plate rotatably connected to the base, a shoulder strap between the base and the cover plate, and a primary locking mechanism for locking or unlocking the base and the cover plate;

[0010] The cover plate is provided with a secondary locking mechanism toward the base, and a pressure plate rotatably connected to the cover plate. When the pressure plate is rotated under force, it approaches or moves away from the secondary locking mechanism, controls the secondary locking mechanism to form a locking force or release the locking force, and completes the locking or unlocking of the shoulder strap.

[0011] Furthermore, the secondary locking mechanism forms a pressing portion facing the shoulder strap, and a pressing surface is formed on the pressing portion.

[0012] Furthermore, the secondary locking mechanism includes a hook protruding toward the base and hung at a set position of the pressure plate.

[0013] Furthermore, the pressure plate is provided with a plurality of slots matching with the hooks along the width direction of the shoulder strap.

[0014] Furthermore, the extrusion portion is linked with a driving mechanism for driving the secondary locking mechanism to rotate.

[0015] Furthermore, a rotating shaft is provided at the end of the cover plate, and an avoidance groove is formed on the pressure plate near the rotating shaft.

[0016] Furthermore, the driving mechanism is a flexible belt arranged along the pressure plate and fixed on the base via an avoidance groove.

[0017] Furthermore, the cover plate forms a cavity structure through which the shoulder strap passes, and the pressing plate is filled in the cavity during rotation.

[0018] Furthermore, the base is recessed to form an assembly cavity with a primary locking mechanism, the cover plate extends downward to form an extension portion matching the assembly cavity, and the pressure plate rotates at the extension portion.

[0019] The utility model also discloses a camera quick-hanging mechanism, comprising a mounting seat formed by the base as described above, and a quick-release plate located on the mounting seat, wherein the camera with the shoulder strap is arranged on the quick-release plate.

[0020] The beneficial effects of the utility model are as follows:

[0021] Firstly, in the present invention, the cover plate and the base are initially locked, and then a secondary locking mechanism is added, so that the shoulder strap is actually locked twice. Compared with other locking methods, this locking method is more secure.

[0022] Secondly, in the utility model, the cover and the base are fitted together by rotation, and then rotated again to form a pressure plate on the cover that fits against the base. Compared with locking methods such as snaps, the method of rotating to produce extrusion is more clever in design and safer to use.

[0023] Thirdly, in the utility model, the hook with the protrusion can be fixed to different positions of the pressure plate to form locking at different positions, thereby realizing locking for pressed parts of different widths, thereby having a wider range of applications and being suitable for popularization and use.

DETAILED DESCRIPTION

[0032] 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.

[0033] See attached Figure 1-6 As shown, the shoulder strap locking mechanism in this embodiment first includes a base 100, an assembly surface is formed on the base 1 for facilitating the placement of the shoulder strap 200, and then includes a cover plate 300 rotatably connected to the base 100, the shoulder strap 200 is located between the base 100 and the cover plate 300, at this time, an initial locking mechanism 400 is added between the base 100 and the cover plate 300, so that when the cover plate 300 is close to the base 100, the two are initially locked, thereby completing the initial locking of the shoulder strap 200, and the locking at this time can be various locking methods such as snap-on.

[0034] In order to ensure a firm lock, in the present embodiment, a secondary lock is also separately provided on the cover plate 300. At this time, the secondary locking mechanism 500 is specifically provided close to the base 100, which is also rotatably connected to the cover plate 300, specifically a pressure plate 510. The pressure plate 510 rotates along the cover plate 300 and then approaches or moves away from the cover plate 300. During this process, the pressure plate 510 controls the secondary locking mechanism 500 to form a locking force, thereby completing the secondary locking of the shoulder strap 200, or moves away from the pressure plate 510 to release the locking force and complete the unlocking.

[0035] When using this embodiment, the secondary locking of the shoulder strap is completed by cleverly utilizing the method of rotating the matching pressure plate. The secondary locking mechanism and the primary locking mechanism are introduced separately below.

[0036] First, an introduction to the secondary locking mechanism.

[0037] As shown in the accompanying drawings, it can be seen that in this embodiment, the pressing plate 510 in the secondary locking mechanism 500 forms a pressing portion 511 facing the shoulder strap 200, and a pressing surface is formed on the pressing portion 511. At this time, the pressing surface is in contact with the shoulder strap 200 to complete the pressing of the shoulder strap 200, and the protrusion forms a local pressing surface, so that the shoulder strap 200 is pressed at a set position, thereby providing the possibility of subsequent position adjustment of the pressing surface and use for shoulder straps of different widths.

[0038] Specifically, in order to facilitate assembly, the secondary locking mechanism is a hook 520 protruding toward the base and hung at a set position of the pressure plate 510. At this time, the hook 520 forms an extrusion surface acting on the strap, and the rotation of the pressure plate drives the hook 520 to rotate, thereby achieving a locking and unlocking process, achieving multiple goals at one stroke.

[0039] In order to expand its application range and make it suitable for shoulder straps of various widths, in this embodiment, a plurality of slots 530 matching with the hooks 520 are provided on the pressing plate 510 along the width direction of the shoulder strap 200. At this time, by matching and assembling with different slots 530, extrusion clamping cavities of different widths are formed to match shoulder straps of different widths.

[0040] In this embodiment, in order to realize the rotation of the pressing plate 510, a driving mechanism 540 for driving the secondary locking mechanism 500 to rotate is linked to the pressing portion 511. Compared with directly driving the pressing plate, in this embodiment, the pressing plate is driven to rotate by driving the pressing portion 511 or the hook 520. On the one hand, the driving mechanism can be hidden inside to ensure safety in use and beautiful appearance. On the other hand, such a driving method drives from the inside and has little impact on the outside of the pressing plate 510.

[0041] Specifically, the rotating shaft 310 is arranged at the end of the cover plate 300, and the pressing plate 510 is formed with an avoidance groove near the rotating shaft 310. By utilizing the avoidance groove, the driving mechanism 540 can extend out of the entire cover plate and avoid the rotation of the two to avoid influence.

[0042] Specifically, the driving mechanism 540 is a flexible belt arranged along the pressing plate 510 and fixed to the base 100 via the avoidance groove. It can also be a knitted belt. In this embodiment, the other end of the driving mechanism 540 is fixed to the base 100. During the rotation, it can be fixedly connected with the pressing plate, and its length will not change. However, since part of the driving mechanism is exposed at the avoidance groove, it is convenient for the user to drive the pressing plate 510 to rotate by operating the exposed flexible connection belt.

[0043] Furthermore, the secondary locking mechanism also includes an unlocking button 550 and a knob connector 570, which are arranged away from the avoidance groove and located on the cavity of the cover 300. A spring tongue 560 is arranged on the pressure plate 510, or the spring tongue 560 is fixedly connected to the hook 520, and then the unlocking button 550 is operated to unlock the pressure plate 510 locked on the cover 300. At this time, it can be rotated by the driving mechanism 540, and then when it is rotated in the opposite direction to close to the base 100, force is applied downward, and the spring tongue 560 enters the cavity to achieve locking. During specific use, when the pressing plate 510 is opened, the shoulder strap 200 is placed between the cover plate 300 and the base 100, the driving mechanism 540 formed by the hook is hung on the pressing plate 510, the pressing plate 510 rotates along the cover plate 300, the driving mechanism 540 formed by the webbing is locked, and finally the pressing plate 510 is covered into the cover plate 300, and the spring tongue 560 is ejected from the cavity of the pressing plate 510 into the cavity of the cover plate 200, locking the pressing plate 510 and preventing it from leaving the cover plate 300, thereby completing the secondary locking.

[0044] Next, the initial locking mechanism 400 is described.

[0045] In this embodiment, the initial locking mechanism 400 is arranged near the avoidance groove. At this time, a buckle can be arranged on one of the cover plate 300 and the base 100, and a slot can be arranged on the other. Then, during the rotation, the buckle and the slot are matched to complete the assembly. The initial locking mechanism at this time can be any one of the methods given in the prior art.

[0046] In this embodiment, the cover plate 300 forms a cavity structure through which the shoulder strap 200 passes, and the pressing plate 510 is filled in the cavity during rotation. Specifically, it can be seen that a portion of the pressing cover 300 is hollowed out, and then the pressing plate 510 is just filled into the hollowed out portion to form a complete structure, which is not only beautiful in structure but also saves raw materials.

[0047] In this embodiment, in order to achieve better assembly, the base 100 is recessed to form an assembly cavity with a primary locking mechanism 400, the cover plate 300 extends downward to form an extension portion 320 matching the assembly cavity, and the pressing plate 510 rotates at the extension portion 320. In this embodiment, the extension portion 320 is an arc-shaped structure, and the rotating shaft 310 is arranged at the arc-shaped structure, so that the friction force during rotation is reduced and the rotation is more convenient.

[0048] Again, for the entire rotation process.

[0049] In this embodiment, it can be seen that the secondary locking is completed by two rotations, and the rotating shafts of the two rotations can be located on the two sides of the base 100, so that the entire force can be dispersed in time to avoid wear and tear occurring only on one side. At the same time, the secondary locking in this embodiment is somewhat similar to the principle of a cam, but it is not just a simple clamping, but also uses a spring tongue, etc., to lock it while the pressure plate is pressed. Specifically, the unlocking button 550 is used to cooperate with the squeezing part 511 to squeeze the shoulder strap 200 for further locking.

[0050] The working principle in this embodiment is as follows:

[0051] The cover plate 300 is hinged to one side (for example, the left side) of the base 100, and the cover plate 300 is rotated to make it close to the base 100, thereby pressing the shoulder strap 200 on the base 100 to achieve the initial fixation, and then the pressing plate 510 hinged to the cover plate 300 can rotate on the left or right side, but preferably on the right side of the base plate, so that both sides rotate and the force is more dispersed. When locking, after the initial locking is completed, the webbing rope (i.e., the driving mechanism 540) on the inner wall hook 520 of the pressing plate 510 is used to start the relevant operation. It can be seen from the driving mechanism at this time that the pressing plate 510 passes through the right side of the pressing plate 510, and then controls it to rotate. During the rotation, the pressing plate 510 is locked to the base 100 and the cover plate body, and drives the cover plate 300 to press down to generate a squeezing force on the shoulder strap 200, thereby achieving the clamping and locking of the shoulder strap 200.

[0052] This embodiment is used in a camera quick-hanging structure for assembling a camera, and then the base 100 is used to form a mounting seat of the quick-hanging structure, and a quick-release plate for assembling the camera is provided on the mounting seat, and then the shoulder strap on the camera can be locked by the structure of this embodiment. And the quick-release plate is located on the mounting seat, and the camera with the shoulder strap is provided on the quick-release plate.
