[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figures 1 to 6 As an embodiment of this utility model, a quick-release locking mechanism includes a quick-release plate 1 and a quick-release base assembly 2. The quick-release plate 1 is provided with a locking screw 11, and the photographic equipment is fixed to the quick-release plate 1 by the locking screw 11. The quick-release base assembly 2 includes a plug-in base 21, a locking base 22 and a locking member 23. The plug-in base 21 is rotatably connected to the locking base 22. One side of the plug-in base 21 has an opening 211 and forms a plug-in groove 212. The locking base 22 is provided with a locking position 221 and an unlocking position 222. When the opening 211 of the plug-in base 21 is located in the unlocking position 222, the quick-release plate 1 is inserted from the opening 211 into the plug-in groove 212. When the plug-in base 21 is rotated so that the opening 211 faces the locking position 221, the locking member 23 pushes the plug-in base 21 to move so that the opening 211 is locked to the locking position 221.

[0034] When the quick-release plate 1 needs to be installed, it is inserted into the insertion slot 212 through the opening 211 on one side of the connector 21. The connector 21 is rotated so that the opening 211 faces the locking position 221. Then, the locking member 23 pushes the connector 21 to move, locking the opening 211 into the locking position 221, thus completing the installation process of the quick-release plate 1. When the quick-release plate 1 needs to be removed, the connector 21 is pushed directly to separate the opening 211 from the locking position 221 by a certain distance. Then, the connector 21 is rotated to the unlocking position 222. At this time, the quick-release plate 1 can be slid off the connector 21 and removed. In this application, the quick-release plate 1 and the quick-release connector do not require an additional unlocking button, making the operation simple and improving the user experience.

[0035] Specifically, the quick-release plate is a square plate structure. The quick-release plate 1 is equipped with a locking screw 11, which is rotatably connected to the quick-release plate 1. The camera equipment has a threaded hole, into which the locking screw 11 can be inserted and locked in place via a threaded connection. At this point, the camera equipment is fixedly connected to the quick-release plate 1. Subsequently, the quick-release plate 1 is installed, achieving a fixed connection between the quick-release plate 1 and the quick-release base assembly 2, thus securing the camera equipment to the quick-release base assembly 2. The quick-release base assembly 2 is typically connected to a support device such as a tripod or monopod. The function of the quick-release plate 1 and the quick-release base assembly 2 is to fix the camera equipment to the support device.

[0036] Furthermore, the locking seat 22 is provided with a guide groove 223, which is an arc-shaped groove. The plug seat 21 is provided with a guide protrusion 213, which is embedded in the guide groove 223 and slidably connected to the guide groove 223. One end of the guide groove 223 is connected to a limiting groove 224. The guide protrusion 213 can slide to the end of the guide groove 223, and the locking member 23 pushes the guide protrusion 213 into the limiting groove 224.

[0037] Specifically, there are two sets of guide grooves 223, which are arranged opposite to each other and can form a circumferential outer contour. The connector 21 has two guide protrusions 213, each of which is embedded in and slidably connected to the corresponding guide groove 223. Through the limiting effect of the two sets of guide grooves 223 and the guide protrusions 213, the rotational position of the connector 21 is limited, allowing the connector 21 to rotate around its center position. One end of each guide groove 223 is connected to a limiting groove 224, which communicates with the guide groove 223. After the guide protrusion 213 slides to the end of the guide groove 223, the locking member 23 pushes the guide protrusion 213 into the limiting groove 224. The limiting groove 224 extends toward the locking position 221. The locking member 23 pushes the guide protrusion 213 into the limiting groove 224, while the opening 211 abuts against the locking position 221 and locks it.

[0038] In other embodiments, the positions of the guide groove 223 and the guide protrusion 213 can be interchanged, that is, the guide protrusion 213 is provided on the locking seat 22, and the guide groove 223 is provided on the plug seat 21.

[0039] In other embodiments, two sets of guide grooves 223 and guide protrusions 213 are also provided. One set of guide grooves 223 and guide protrusions 213 is provided on the locking seat 22, and the other set of guide grooves 223 and guide protrusions 213 is provided on the plug seat 21. The guide protrusions 213 of one set are embedded in the guide grooves 223 of the other set.

[0040] Furthermore, the locking seat 22 is provided with a sliding groove 225, and the plug-in seat 21 is provided with a slider 214. The slider 214 can rotate and slide within the sliding groove 225. The locking element 23 is a torsion spring, which abuts against the slider 214.

[0041] Specifically, the slider 214 is positioned at the center of the connector 21. The slider 214 is cylindrical in shape, and a groove 225 is disposed on the locking seat 22. The groove 225 includes a first part 2251 and a second part 2252. The slider 214 is rotatably connected to the first part 2251 and slidably connected to the second part 2252. In this embodiment, to facilitate the processing of the groove 225, it is designed as an oblong groove. One end of the oblong groove forms the first part 2251, facilitating the rotation of the slider 214, while the remaining part forms the second part 2252, facilitating the sliding of the slider 214. The extension direction of the second part 2252 is parallel to the extension direction of the limiting groove 224, so that the second part 2252 has the same function as the limiting groove 224, serving as a guide to facilitate the opening 211 abutting against the locking position 221 and achieving locking.

[0042] In this embodiment, after the guide protrusion 213 slides to the end of the guide groove 223, it is pushed into the limiting groove 224 by the thrust of the torsion spring. At the same time, the slider 214 is pushed from the first part 2251 of the slide groove 225 to the second part 2252 of the slide groove 225. In this embodiment, the locking seat 22 is provided with a mounting groove 226. One end of the torsion spring is installed in the mounting groove 226, and the other end is a movable end that abuts against the slider 214. The torsion spring always has a resisting force on the slider 214. The locking member 23 uses a torsion spring to ensure that the slider 214 can rotate while abutting against the torsion spring. When the slider 214 rotates, it can maintain normal abutment with the torsion spring.

[0043] In other embodiments, the locking member 23 may also be a spring, with one end of the spring fixed to the locking seat 22 and the other end always maintaining contact with the slider 214.

[0044] In other embodiments, the slide groove 225 structure can be omitted, in which case the slider 214 only serves to keep in contact with the locking member 23.

[0045] Furthermore, the locking seat 22 is also provided with a baffle 227, which can cover the locking component 23. On the one hand, it can protect the locking component 23, and on the other hand, it can improve the overall appearance of the quick-release seat assembly 2.

[0046] Specifically, the guide groove 223, the limiting groove 224, and the sliding groove 225 are all through-groove structures. The guide protrusion 213 and the slider 214 are both provided with threaded holes. Screws pass through the baffle 227 and connect to the threaded holes, allowing the baffle 227 to be installed on the locking seat 22. After locking, the baffle 227 not only blocks the locking element 23 but also rotates and slides with the connector 21 without interfering with its movement. In this embodiment, to improve the appearance of the locking seat 22, an embedding groove is provided. After installation, the baffle 227 is directly embedded into the embedding groove. During installation, the tightness of the screws must be controlled to prevent the baffle 227 from locking and becoming immobile, which would prevent the connector 21 from rotating and moving.

[0047] In other embodiments, the baffle 227 can also be fixed to the locking seat 22. In this case, the baffle 227 does not move with the plug seat 21, and the baffle 227 only blocks components such as the locking member 23, guide groove 223, limiting groove 224, and sliding groove 225. In this case, limiting members need to be provided for components such as the guide protrusion 213 and the slider 214 to ensure that they do not disengage when sliding in the guide groove 223 and sliding groove 225.

[0048] Furthermore, the locking position 221 is provided with a locking block 228, which abuts against the quick-release plate 1. The unlocking position 222 is provided with a stop block 229, which abuts against the plug socket 21.

[0049] Specifically, the shape of the locking block 228 is adapted to the outer contour edge shape of the quick-release plate 1. The quick-release plate 1 is inserted into the insertion slot 212 from the opening 211 of the insertion seat 21. After insertion, the edge of the quick-release plate 1 near the opening 211 is exposed. When the insertion seat 21 rotates so that the opening 211 faces the locking position 221, the locking member 23 pushes the insertion seat 21 to move so that the exposed side of the quick-release plate 1 abuts against the locking block 228. Through the elastic abutment action of the locking member 23 and the limiting abutment action of the locking block 228, the quick-release plate 1 can be locked in the insertion slot 212, completing the installation process of the quick-release plate 1. When it is necessary to remove the quick-release plate 1, push the connector 21 directly, and then rotate the connector 21 in the opposite direction. During the rotation, the connector 21 abuts against the stop 229 and cannot rotate. At this time, the connector 21 rotates to the position, and the opening 211 of the connector 21 rotates to the unlock position 222, so that the quick-release plate 1 can be slid off the connector 21 and removed.

[0050] In other embodiments, the stop 229 can be omitted. During the process of removing the quick-release plate 1, the plug-in 21 should be rotated simultaneously and observed until it stops rotating automatically after it has reached the correct position.

[0051] The quick-release locking mechanism in this embodiment is easy to operate, and the specific operation is as follows:

[0052] When the quick-release plate 1 needs to be installed, the quick-release plate 1 is inserted into the insertion slot 212 from the opening 211 on one side of the insertion base 21. The insertion base 21 is rotated so that the opening 211 faces the locking position 221. Then the locking member 23 pushes the insertion base 21 to move so that the opening 211 is locked to the locking position 221, thus completing the installation process of the quick-release plate 1.

[0053] When it is necessary to remove the quick-release plate 1, simply push the connector 21 to separate the opening 211 of the connector 21 from the locking position 221 by a certain distance. Then rotate the connector 21 to rotate the opening 211 to the unlocking position 222. At this time, the quick-release plate 1 can be slid off the connector 21 and removed. In this application, the quick-release plate 1 and the quick-release connector do not require an additional unlocking button, making operation simple and improving the user experience.

[0054] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
