The terminology used in the description of the present application in this description is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-7, a first embodiment of the present application provides a quick release component 10 that is convenient for the disassembly and assembly operations of the quick release component 10 itself. For convenience of description, in this embodiment, the application of the quick release component 10 to the field of photographic equipment technology is illustrated.

Specifically, the quick release member 10 includes a first member 100, a second member 200, a locking member 300, and a first reset member 400. In this embodiment, the first component 100 is a movable component for connecting with a camera or the like, and the second component 200 is a fixed component for connecting with a tripod head or the like, and the tripod head is usually mounted on a tripod in actual use. The first component 100 and the second component 200 are assembled and disassembled, so that the camera, the tripod head and the tripod are assembled and disassembled. Of course, in other embodiments, the first component 100 may be connected to a tripod, and the second component 200 may be connected to a camera, which is not described herein.

The second member 200 includes a mounting portion 210 provided with a fixing groove 211, and the fixing groove 211 is used for the assembly of the first member 100. The fixing groove 211 extends in the axial direction of the second member 200 (i.e., in the direction of the central axis 241) with its tip as a notch 2111 into which the first member 100 is inserted. The second member 200 further includes a first locking portion 290 connected to the mounting portion 210, wherein the first member 100 extending into the fixing groove 211 can be locked when the first locking portion 290 is in the locking position, and the first member 100 can be released when the first locking portion 290 is in the releasing position. When the first component 100 extends into the corresponding position in the fixing groove 211 and the first locking portion 290 is at the locking position, the first component 100 can be locked, so that the connection between the first component 100 and the second component 200 is completed, and the quick installation of the camera and the tripod is further realized.

The locking member 300 is movably connected to the mounting portion 210, and the locking member 300 can move to a first position and a second position relative to the mounting portion 210, that is, the locking member 300 can reciprocate between at least the first position and the second position (the locking member 300 moves to the first position and the second position are both moved relative to the mounting portion 210 in the present application). The locking member 300 may be slid along a straight line or curve to the first position or the second position, or the locking member 300 may be rotatable to the first position or the second position. In this embodiment, the locking member 300 slides along a straight line to the first position or the second position. The locking member 300 is configured to drive the first locking portion 290 to the locking position during movement to the first position, and to enable the first locking portion 290 to retract to the release position when moved to the second position.

When the first member 100 is inserted into the corresponding position in the fixing groove 211, the locking member 300 can drive the first locking portion 290 to move from the release position to the locking position after the locking member 300 moves from the second position to the first position, so that the locking of the first member 100 is achieved, and when the locking member 300 moves from the first position to the second position, the first locking portion 290 can move to the release position, so that the first member 100 can be separated from the mounting portion 210. It should be noted that the locking member 300 may be directly driven or indirectly driven by other components for driving the first locking portion 290. In this embodiment, the locking member 300 directly drives the first locking portion 290. When the locking member 300 moves to the second position, the first locking portion 290 can return to the release position by itself (e.g. using gravity), or can return to the release position by using other elastic members or magnetic members, or can return to the release position by pushing the first locking portion 290 when the first member 100 extends out of the fixing slot 211.

In summary, in the present embodiment, when the locking member 300 is located at the first position, the first component 100 can be mounted to the second component 200. When the locking member 300 is in the second position, the first member 100 can be separated from the second member 200.

The first restoring member 400 is connected to the locking member 300 and the mounting portion 210, respectively, and the first restoring member 400 generates a force to drive the locking member 300 to move to the first position. In this embodiment, the locking member 300 can be kept at the first position, and when the operator does not push the first reset member 400 to slide relative to the mounting portion 210, the first reset member 400 can push the locking member 300 to be at the first position. The first restoring member 400 may be a spring or a magnetic member, and in this embodiment, the first restoring member 400 is a spring.

When the quick release structure has only the above-described structure, if the first member 100 needs to be installed, an operator needs to press the locking member 300 with one hand and hold the locking member 300 at the second position, so that the first member 100 can be extended into the corresponding position of the fixing groove 211 (when the locking member 300 is at the first position, since the first locking portion 290 is located at the locking position, the first member 100 cannot be extended into the corresponding position of the fixing groove 211). When the operator's other hand extends the first member 100 into the corresponding position of the fixing groove 211 and releases the locking member 300, the first restoring member 400 can push the locking member 300 to the first position by releasing the hand holding the locking member 300, thereby completing the final locking of the first member 100. In the above operation, the operator needs to operate with two hands, and the hand holding the lock 300 needs to be continuously applied with force, which is inconvenient.

In view of this, in the present embodiment, the second member 200 further includes the second locking portion 270 and the unlocking portion 281, and the second locking portion 270 is configured to lock the locking member 300 when the locking member 300 is in the second position. The unlocking portion 281 is configured to be able to drive the second locking portion 270 to release the locking member 300 after the driving force is obtained, and to be able to give the driving force to the unlocking portion 281 in the process that the first member 100 is inserted into the fixing groove 211. That is, when the operator slides the locking member 300 to the second position, the second locking portion 270 locks the locking member 300, and the operator may not continuously apply force to the locking member 300. When the user stretches the first component 100 into the fixing groove 211, the unlocking portion 281 can be driven to move, so that the unlocking portion 281 drives the second locking portion 270 to release the locking piece 300, and the locking piece 300 can return to the first position under the driving of the first resetting piece 400, so that the first locking portion 290 locks the first component 100.

In the quick release component 10 of the present embodiment, when the first component 100 and the second component 200 are mounted, an operator can slide the locking member 300 relative to the second component 200 to the second position by one hand (at this time, the second locking portion 270 can lock the locking member 300, so that the operator can leave the locking member 300 by hand), and then can insert the first component 100 into the fixing slot 211 by one hand. The unlocking portion 281 is driven during the process that the first member 100 is inserted into the fixing groove 211, so that the second locking portion 270 releases the locking member 300, thereby enabling the locking member 300 to move to the first position, and further enabling the first locking portion 290 to lock the first member 100. The whole installation process can be completed by only one hand of a user, and the installation process is convenient and quick.

The specific structure of the first locking portion 290 for locking the first member 100 depends on the actual requirement, and in this embodiment, the mounting portion 210 includes an annular wall 240 disposed around a central axis 241, and the fixing groove 211 is disposed in the annular wall 240. The mounting portion 210 is provided with a first mounting hole 220, and the first mounting hole 220 penetrates the annular wall 240 in the radial direction and communicates with the fixing groove 211. The first locking portion 290 is provided to the first mounting hole 220, and the first locking portion 290 is movable to a locking position protruding into the fixing groove 211 in a direction toward the central axis 241 in a radial direction or to an unlocking position protruding out of the annular wall 240 in a direction away from the central axis 241 in a radial direction. In this embodiment, the first member 100 may be provided with a groove that cooperates with the first locking portion 290, and the first member 100 may be locked when the inner end of the first locking portion 290 extends into the fixing groove 211 and is inserted into the groove of the first member 100. In other embodiments, the first locking portion 290 may also lock the first member 100 by a pressing force against the first member 100.

The quick release member 10 further includes a second restoring member 251, the second restoring member 251 being connected to the mounting portion 210 and the first locking portion 290, respectively, the second restoring member 251 generating a driving force for moving the first locking portion 290 to the unlocking position. That is, after the locking member 300 slides to the second position, the second reset member 251 can drive the first locking portion 290 to the second position protruding out of the annular wall 240, thereby achieving locking of the first component 100.

The locking member 300 is disposed on the outer side of the annular wall 240, i.e., on the side radially away from the central axis 241, and the locking member 300 slides linearly in the axial direction, so that the first locking portion 290 is pushed to move to the locking position in the direction approaching the central axis 241 during the movement of the locking member 300 to the first position.

Specifically, the locking member 300 is annular and is sleeved outside the annular wall 240, and the locking member 300 is configured to be capable of sliding along the central axis 241 with respect to the mounting portion 210, to a first position in a direction toward the notch 2111 of the fixing groove 211, or to a second position in a direction away from the notch 2111 of the fixing groove 211. In the present embodiment, the locking member 300 can push the first locking portion 290 to slide up and down by using the inner circumferential wall 310.

The first resetting member 400 is disposed between the locking member 300 and the annular wall 240, the first resetting member 400 is a spring, the spring is sleeved outside the annular wall 240, an end portion of the spring, which is away from the notch 2111, abuts against the mounting portion 210, and an end portion of the spring, which is close to the notch 2111, abuts against the locking member 300.

The mounting portion 210 is provided with a second mounting hole 230, and the second locking portion 270 is movably provided in the second mounting hole 230, and is capable of sliding in a direction perpendicular to the central axis 241, i.e., radially outward to protrude from the annular wall 240 and lock the locking member 300 in the second position, or radially inward to a position releasing the locking member 300.

The quick release member 10 further includes a third restoring member 252, the third restoring member 252 being embodied as a spring, the third restoring member 252 being provided in the second mounting hole 230, and the third restoring member 252 being capable of generating a driving force for moving the second locking portion 270 to a position extending out of the annular wall 240 and locking the locking member 300. The second locking portion 270 can be pushed to slide in the direction approaching the central shaft 241 during the process of moving the locking member 300 to the second position, and the third reset member 252 drives the second locking portion 270 to slide in the direction departing from the central shaft 241 after the locking member 300 moves to the second position, so that the second locking portion 270 locks the locking member 300.

The inner peripheral wall 310 of the lock 300 is provided with an annular protrusion 320 arranged around the central axis 241, the annular protrusion 320 being provided with a first annular wall 322 and a first inclined wall 321, the first annular wall 322 being axially opposite to the first inclined wall 321, the first annular wall 322 facing the notch 2111, the first inclined wall 321 facing away from the notch 2111. In the process of moving the locking member 300 from the first position to the second position, the first inclined wall 321 can push the second locking portion 270 to slide towards the direction approaching the central shaft 241, and after the annular protrusion 320 slides over the second locking portion 270, the second locking portion 270 is pushed by the third reset member 252 to make the second locking portion 270 abut against the first annular wall 322, so that the second locking portion 270 locks the locking member 300.

The inner peripheral wall 310 of the locking member 300 is further provided with a second inclined wall 330 surrounding the central axis 241, the second inclined wall 330 being located on the side of the annular protrusion 320 adjacent to the notch 2111, the second inclined wall 330 being configured to urge the first locking portion 290 to extend beyond the annular wall 240 and thereby urge the first locking portion 290 to the locking position during sliding of the locking member 300 from the second position to the first position.

The unlocking member 280 is disposed at the bottom of the fixing groove 211, i.e., at the end of the fixing groove 211 facing away from the notch 2111, and the unlocking member 280 is configured to push the second locking portion 270 to move in a direction approaching the central shaft 241 when moving in a direction facing away from the notch 2111.

The quick release member 10 further includes a fourth restoring member 253, the fourth restoring member 253 being connected to the mounting portion 210 and the unlocking member 280, respectively, the fourth restoring member 253 being configured to generate a driving force for moving the unlocking member 280 in a direction toward the notch 2111.

The unlocking member 280 includes an unlocking portion 281, the unlocking member 280 may extend into the second mounting hole 230, the unlocking portion 281 includes a third inclined wall 2811, the second locking portion 270 includes a fourth inclined wall 271, the third inclined wall 2811 is located between the fourth inclined wall 271 and the notch 2111 in the axial direction, and the third inclined wall 2811 is located outside the fourth inclined wall 271 in the radial direction, i.e., on a side away from the central axis 241, and when the unlocking portion 281 moves in a direction away from the notch 2111, the third inclined wall 2811 abuts against the fourth inclined wall 271, thereby pushing the second locking portion 270 to move in a direction close to the central axis 241.

The specific installation process of the quick release component 10 in this embodiment is as follows:

the operator pushes the locking member 300 located at the first position (a position close to the notch 2111 of the fixing groove 211) to the second position in a direction away from the notch 2111 of the fixing groove 211, and during the sliding of the locking member 300 to the second position, the first locking portion 290 is driven by the second restoring member 251 to retract from the locking position to the release position (a position protruding from the annular wall 240 of the mounting portion 210), thereby enabling the first member 100 to be protruded into the corresponding position of the fixing groove 211. In the process of sliding the locking member 300 to the second position, under the cooperation of the annular protrusion 320 and the second locking portion 270, the second locking portion 270 is pushed by the locking member 300 to move in a direction approaching the central shaft 241, and after the locking member 300 is in the second position, the second locking portion 270 moves in a direction deviating from the central shaft 241 to lock the locking member 300, so that the locking member 300 is kept in the second position.

The operator extends the first member 100 into the fixation groove 211, pushing the unlocking member 280 to move in a direction away from the notch 2111 of the fixation groove 211 when the first member 100 abuts the unlocking member 280. With the engagement of the unlocking portion 281 and the second locking portion 270, the unlocking portion 281 urges the second locking portion 270 to move in a direction approaching the central axis 241 to a position where the lock 300 can be released. After the first member 100 extends into the corresponding position of the fixing groove 211 and the locking member 300 is released, the first reset member 400 pushes the locking member 300 to move to the first position, and the first locking portion 290 is pushed to move to the locking position for locking the first member 100 in the process of moving the locking member 300 to the first position, so that the final locking of the first member 100 is completed.
