[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Please also read Figures 1 to 10 The quick release mechanism 100 provided in the embodiment of the present application is now described. The quick release mechanism 100 is mainly used to detachably connect the lamp body to the bracket 200. Of course, it can also be used to connect photographic equipment to the bracket 200, and can also be used for other two parts that need to be detachably connected.

[0038] Please also read Figure 1 and Figure 5 The quick release mechanism 100 includes a base 10, an adapter block 20, a locking assembly 30 and a limiting assembly 40. The base 10 is provided with a mounting groove 11; the adapter block 20 is installed in the mounting groove 11; the locking assembly 30 is movably arranged on the base 10 so as to be able to switch between a locked state and an unlocked state, and when the locking assembly 30 is in the unlocked state, the locking assembly 30 acts on the adapter block 20 to lock the adapter block 20 in the mounting groove 11; the locking assembly 30 is provided with a limiting hole 311; the limiting assembly 40 is movably arranged on the base 10 and slidably cooperates with the locking assembly 30. When the locking assembly 30 is switched to the unlocked state, the limiting assembly 40 can be snapped into the limiting hole 311.

[0039] Among them, the base 10 is used to connect with the lamp body, and the adapter block 20 is used to connect with the bracket 200; or, the base 10 is used to connect with the bracket 200, and the adapter block 20 is used to connect with the lamp body, and the detachable connection between the lamp body and the bracket 200 is achieved through the detachable connection between the adapter block 20 and the base 10.

[0040] By movably setting the locking assembly 30 on the base 10, the locking assembly 30 can be switched between a locked state and an unlocked state, and when the locking assembly 30 is in the locked state, the locking assembly 30 can act on the adapter block 20 to lock the adapter block 20 in the mounting groove 11, and at this time, the adapter block 20 cannot be separated from the mounting groove 11. When the locking assembly 30 is in the unlocked state, the locking assembly 30 does not act on the adapter block 20, and at this time, the adapter block 20 can be taken out of the mounting groove 11. It can be understood that the adapter block 20 is locked and unlocked by the locking assembly 30, so that the adapter block 20 and the base 10 are detachably connected.

[0041] By movably setting the limiting component 40 on the base 10 and slidingly cooperating with the locking component 30, in this way, when the locking component 30 switches between the locked state and the unlocked state, the locking component 30 slides relative to the limiting component 40, that is, the position of the locking component 30 relative to the limiting component 40 changes. When the locking component 30 switches to the unlocked state, the limiting hole 311 on the locking component 30 corresponds to the limiting component 40. At this time, the locking component 30 can be inserted into the limiting hole 311 to prevent the locking component 30 from returning to the locked state from the unlocked state.

[0042] Compared with the prior art, the quick-release mechanism 100 provided in the present application has one of the base 10 and the adapter block 20 used to connect to the lamp body, and the other used to connect to the bracket 200. The adapter block 20 is locked and unlocked by switching the locking assembly 30 between the locked state and the unlocked state, so that the adapter block 20 and the base 10 are detachably connected, and then the lamp body and the bracket 200 are detachably connected. By providing a movable limiting assembly 40 that slidably cooperates with the locking assembly 30 on the base 10, when the locking assembly 30 is switched to the unlocked state, the limiting hole 311 on the locking assembly 30 corresponds to the limiting assembly 40. At this time, the locking assembly 30 can be inserted into the limiting hole 311 to prevent the locking assembly 30 from returning to the locked state from the unlocked state, so that the locking assembly 30 is always maintained. In the unlocked state, there is no need to continuously apply external force to the locking assembly 30. Specifically, when the lamp body needs to be removed from the bracket 200, the user applies external force to the locking assembly 30 with one hand to switch the locking assembly 30 from the locked state to the unlocked state. When the locking assembly 30 is in the unlocked state, the locking assembly 30 is inserted into the limiting hole 311 to limit the locking assembly 30 to the unlocked state. At this time, the external force on the locking assembly 30 is canceled, that is, the user's hand leaves the locking assembly 30, and the locking assembly 30 can also remain in the unlocked state, so that the user can free his hands to perform the next operation, such as removing the adapter block 20 from the mounting groove 11. The quick release mechanism 100 is easy to use and can quickly and easily remove the lamp body from the bracket 200, which can meet the quick release requirements.

[0043] In one embodiment of the present application, see Figure 1 and Figure 2 The adapter block 20 is slidably matched with the mounting groove 11. The adapter block 20 is slidably matched with the mounting groove 11 along a first direction F1. For example, the adapter block 20 can slide into the mounting groove 11 along the first direction F1 or slide out of the mounting groove 11 along a second direction F2 opposite to the first direction F1.

[0044] Specifically, the two opposite ends of the base 10 along the first direction F1 are respectively a first end 12 and a second end 13, the mounting groove 11 passes through the first end 12, and the adapter block 20 can slide into the mounting groove 11 from the first end 12 along the first direction F1, and slide out of the mounting groove 11 from the first end 12 along the direction opposite to the first direction F1.

[0045] It can be understood that the installation groove 11 does not pass through the second end 13, that is, the second end 13 is a closed structure. After the adapter block 20 slides into place, one end of the adapter block 20 abuts against the second end 13, so that the user can use this as a basis to judge whether the adapter block 20 is installed in place. At the same time, by abutting one end of the adapter block 20 against the second end 13, the stability of the adapter block 20 in the installation groove 11 is effectively improved.

[0046] The above technical solution can easily and quickly install the adapter block 20 into the installation groove 11 by slidingly matching the adapter block 20 with the installation groove 11, which is easy to operate.

[0047] Furthermore, the width of the mounting groove 11 gradually decreases from the first end 12 to the second end 13, that is, the mounting groove 11 is roughly trapezoidal or wedge-shaped, and the adapter block 20 matches the mounting groove 11, that is, the width of the adapter block 20 also gradually decreases from the first end 12 to the second end 13, and the adapter block 20 is also roughly trapezoidal or wedge-shaped.

[0048] The above technical solution gradually reduces the width of the installation groove 11 and the adapter block 20 from the first end 12 to the second end 13, so that the adapter block 20 is easier to align and slide into the installation groove 11 during installation, which is beneficial to improving the convenience of operation.

[0049] In some embodiments, the mounting groove 11 passes through a side surface of the base 10 to form a notch, the mounting groove 11 has a bottom surface, and the bottom surface is arranged opposite to the notch. The mounting groove 11 is a dovetail groove, and the adapter block 20 is a dovetail structure. The cooperation between the dovetail structure and the dovetail groove is beneficial to improve the stability of the adapter block 20 installed in the mounting groove 11.

[0050] Of course, in other embodiments, the adapter block 20 may also be embedded in the installation groove 11, that is, the installation groove 11 does not penetrate the first end 12 and / or the second end 13, and the adapter block 20 is directly embedded in the installation groove 11 from the side where the groove is located.

[0051] In one embodiment of the present application, see Figure 3 , Figure 5 and Fig.10 The base 10 is also provided with a receiving cavity 14, an opening 16 communicating with the receiving cavity 14, and a through-hole 17 communicating with the receiving cavity 14 and the mounting groove 11. The locking assembly 30 and the limiting assembly 40 are both arranged in the receiving cavity 14. One end of the locking assembly 30 extends out of the base 10 at the opening 16. When the locking assembly 30 is in a locked state, the locking assembly 30 passes through the through-hole 17 and abuts against the adapter block 20.

[0052] The opening 16 is provided at the second end 13 of the base 10 , and one end of the locking assembly 30 extends from the opening 16 to the second end 13 . The user can switch the locking assembly 30 between the locked state and the unlocked state by operating the end of the locking assembly 30 extending from the opening 16 .

[0053] The through opening 17 is provided at one side of the mounting groove 11. When the locking assembly 30 switches from the unlocked state to the locked state, part of the locking assembly 30 extends through the through opening 17 into the mounting groove 11 and abuts against the adapter block 20 to lock the adapter block 20 in the mounting groove 11. When the locking assembly 30 switches from the locked state to the unlocked state, the locking assembly 30 withdraws from the mounting groove 11 to release the abutment against the adapter block 20.

[0054] The above technical solution, by opening a receiving cavity 14 on the base 10, arranges the locking assembly 30 and the limiting assembly 40 in the receiving cavity 14, so that the overall structure of the quick release mechanism 100 is more compact and the overall volume is smaller, which is beneficial to reducing the space occupied by the quick release mechanism 100. At the same time, it can make the quick release mechanism 100 as a whole tidy, which is beneficial to beautify the appearance. In addition, one end of the locking assembly 30 extends out of the base 10 at the opening 16, which is convenient for the user to operate the locking assembly 30.

[0055] In one embodiment of the present application, see Figure 5 , Fig. 9 and Fig.10 The locking assembly 30 includes a push block 31 that slides with the base 10, a slider 32 that slides with the base 10, a second elastic member 33 that abuts against the push block 31, and a third elastic member 34 that abuts against the slider 32. One end of the push block 31 extends to the outside of the base 10 through the opening 16, and the slider 32 cooperates with the push block 31 in transmission. When the locking assembly 30 is in a locked state, one end of the slider 32 extends through the through opening 17 into the mounting groove 11 and abuts against the adapter block 20. A limiting hole 311 is provided on the push block 31.

[0056] By driving the slider 32 and the push block 31 together and pressing the push block 31 so that the push block 31 slides relative to the base 10, the push block 31 can drive the slider 32 to slide relative to the base 10, so that the slider 32 protrudes through the through opening 17 into the installation groove 11 or exits the installation groove 11, thereby realizing the locking assembly 30 sliding between the locked state and the unlocked state.

[0057] When the locking assembly 30 is in the unlocked state, the second elastic member 33 and the third elastic member 34 are both in a compressed state, wherein the second elastic member 33 abuts against the push block 31, so that the push block 31 has a tendency to return to its original position, and the third elastic member 34 abuts against the slider 32, so that the slider 32 has a tendency to move toward the push block 31. Therefore, when the locking assembly 30 is in the locked state, the slider 32 can extend through the through opening 17 to the mounting groove 11 and abut against the adapter block 20 under the action of the third elastic member 34, so as to lock the adapter block 20 in the mounting groove 11.

[0058] In one embodiment of the present application, see Figure 7 and Figure 8 , the sliding direction of the push block 31 is perpendicular to the sliding direction of the slider 32. Specifically, the push block 31 and the base 10 slide together in the second direction F2, so that the push block 31 can reciprocate along the second direction F2. It can be understood that the sliding direction of the push block 31 is parallel to the sliding direction of the adapter block 20. The slider 32 and the base 10 cooperate in the third direction F3, so that the slider 32 can reciprocate along the third direction F3, and the third direction F3 is perpendicular to the second direction F2. The push block 31 has a first contact surface 312 which is tilted relative to the sliding direction of the push block 31. The first contact surface 312 is disposed at an end of the push block 31 away from the opening 16. The slider 32 has a second contact surface 321 which is tilted relative to the sliding direction of the slider 32. The second contact surface 321 is disposed at an end of the slider 32 close to the push block 31. The second contact surface 321 cooperates with the first contact surface 312 to contact. In this way, when the push block 31 is pressed to move along the second direction F2, the first contact surface 312 cooperates with the second contact surface 321 to push the slider 32 to move along the third direction F3, so that the slider 32 exits the mounting groove 11.

[0059] Optionally, the second elastic member 33 may be a spring or other elastic member. One end of the second elastic member 33 abuts against the base 10, and the other end abuts against the end of the push block 31 away from the opening 16. Fig.10 Of course, the second elastic member 33 may also abut against other parts of the push block 31 as long as it can drive the push block 31 to reset.

[0060] Optionally, the third elastic member 34 may be a spring or other elastic member. One end of the third elastic member 34 abuts against the base 10, and the other end abuts against the end of the slider 32 away from the push block 31. Fig.10Of course, the third elastic member 34 may also abut against other parts of the push block 31 , as long as it can drive the slider 32 to abut against the adapter block 20 .

[0061] In some embodiments of this application, please refer to Figure 7 and Fig.10 The base 10 is provided with a first guide column 18, and the push block 31 is provided with a first guide groove 314 extending along the sliding direction of the push block 31. The first guide column 18 is movably arranged in the first guide groove 314. When the push block 31 slides relative to the base 10, the first guide column 18 cooperates with the first guide groove 314 to guide the push block 31, thereby effectively preventing the push block 31 from deflecting.

[0062] In some embodiments of the present application, a second guide column 19 is provided on the base 10, and the slider 32 is provided with a second guide groove 322 extending along the sliding direction of the slider 32, and the second guide column 19 is movably inserted into the second guide groove 322. When the slider 32 slides relative to the base 10, the second guide column 19 cooperates with the second guide groove 322 to guide the slider 32, thereby effectively preventing the slider 32 from deflecting.

[0063] Optionally, see Fig.10 A first boss 141 is provided on the base 10, and the first boss 141 is located in the accommodating cavity 14 and close to the opening 16. A second boss 315 is provided on the push block 31, and the second boss 315 is close to the opening 16. When the locking assembly 30 is in the locked state, the first boss 141 is engaged with the second boss 315 to prevent the push block 31 from completely separating from the accommodating cavity 14 from the opening 16.

[0064] In one embodiment of the present application, see Figure 3 , Figure 7 and Fig. 9 A protrusion 323 is provided at one end of the slider 32 away from the push block 31, and a groove 21 is provided on the adapter block 20. The groove 21 is provided on one side of the adapter block 20 along the sliding direction of the adapter block 20. When the locking assembly 30 is in a locked state, the protrusion 323 passes through the through opening 17 and is inserted into the groove 21 to prevent the adapter block 20 from moving in the installation groove 11, thereby locking the adapter block 20 in the installation groove 11.

[0065] Furthermore, a guide surface 324 is provided at one end of the protrusion 323 close to the first end 12, and the guide surface 324 is inclined in the direction of the first end 12. In the process of the adapter block 20 sliding into the installation groove 11, the adapter block 20 pushes the protrusion 323 to exit the installation groove 11 through the guide surface 324. After the adapter block 20 slides into place, the protrusion 323 corresponds to the groove 21, and the protrusion 323 automatically passes through the opening 17 and is stuck in the groove 21 under the action of the third elastic member 34, so that the adapter block 20 is automatically locked in the installation groove 11, which is convenient to operate.

[0066] It should be noted that when the locking assembly 30 is in the unlocked state, the limiting assembly 40 can be actively inserted into the limiting hole 311, or can be passively inserted into the limiting hole 311. The active insertion of the limiting assembly 40 into the limiting hole 311 means that the limiting assembly 40 can be automatically inserted into the limiting hole 311 without external force control, while the passive insertion of the limiting assembly 40 into the limiting hole 311 means that the user needs to apply external force to the limiting assembly 40 to insert the limiting assembly 40 into the limiting hole 311.

[0067] Specifically in this embodiment, when the locking assembly 30 is switched to the unlocking state, the limiting assembly 40 is actively inserted into the limiting hole 311 .

[0068] For example, see Figure 5 and Figure 6 The limiting assembly 40 includes a limiting column 41 and a first elastic member 42 . The first elastic member 42 abuts against the limiting column 41 . When the locking assembly 30 is switched to the unlocked state, the limiting column 41 can be inserted into the limiting hole 311 under the action of the first elastic member 42 .

[0069] The first elastic member 42 may be a spring or other elastic member.

[0070] Specifically, when the limit column 41 is misaligned with the limit hole 311, the locking assembly 30 abuts against the limit column 41, and the first elastic member 42 is in a compressed state. When the locking assembly 30 switches to the unlocked state, the limit column 41 is opposite to the limit hole 311, and the first elastic member 42 generates elastic expansion, pushing the limit column 41 to be inserted into the limit hole 311.

[0071] By cooperating with the limiting column 41 and the first elastic member 42, when the limiting column 41 is facing the limiting hole 311, the limiting column 41 is automatically snapped into the limiting hole 311 under the action of the first elastic member 42, so that the limiting component 40 is actively snapped into the limiting hole 311, which is beneficial to improving the convenience of operation.

[0072] Furthermore, the limiting assembly 40 also includes a fixed column 43, one end of which is connected to the base 10, the limiting column 41 is movably mounted on the fixed column 43, the first elastic member 42 is a coil spring, and is movably mounted on the fixed column 43, one end of the first elastic member 42 abuts against the limiting column 41, and the other end abuts against the fixed column 43 or the base 10.

[0073] Optionally, the fixing column 43 may be a component such as a screw or a bolt, which can facilitate and quickly fix the fixing column 43 on the base 10 .

[0074] The limiting column 41 is provided with a sleeve hole, and the limiting column 41 is sleeved on the fixing column 43 through the sleeve hole.

[0075] By movably sleeved the limit column 41 on the fixed column 43, the limit column 41 is made to move relatively along the axial direction of the fixed column 43, thereby guiding the movement of the limit column 41 and effectively preventing the limit column 41 from deviating, so that the limit column 41 can be accurately inserted into the limit hole 311. By setting the first elastic member 42 as a coil spring and movably sleeved on the fixed column 43, the first elastic member 42 is guided when it is axially deformed, effectively preventing the first elastic member 42 from being lateral skewed.

[0076] In one embodiment of the present application, see Figures 5 to 8 The locking assembly 30 is also provided with a clearance channel 313, one end of which is connected to the limiting hole 311. The limiting column 41 includes a column 411 and a clamping portion 412 connected to one end of the column 411. The column 411 is movably arranged in the clearance channel 313 or the limiting hole 311. The width of the clamping portion 412 is greater than the width of the clearance channel 313 and less than the width of the limiting hole 311.

[0077] The clearance channel 313 is arranged on the movable path of the locking assembly 30. Specifically, the clearance channel 313 is arranged on the push block 31 and extends along the sliding direction of the push block 31. The limiting column 41 can move relatively in the clearance channel 313 and the limiting hole 311 along the first direction F1 or the second direction F2.

[0078] The circumferential edge of the clamping portion 412 protrudes out of the circumferential edge of the first guide column 18, that is, the width of the clamping portion 412 is greater than the width of the column 411. Optionally, the column 411 and the clamping portion 412 are integrally formed.

[0079] Specifically, when the locking assembly 30 is in the locked state or switches from the locked state to the unlocked state, the limiting column 41 is penetrated through the clearance channel 313 and slidably cooperates with the clearance channel 313. Since the width of the clamping portion 412 is greater than the width of the clearance channel 313, the clamping portion 412 cannot be clamped into the clearance channel 313, and the first elastic member 42 is in a compressed state. Figure 6 and Figure 8 When the locking assembly 30 is in the unlocked state, the limiting column 41 is inserted into the limiting hole 311, and the clamping portion 412 corresponds to the limiting hole 311. Since the width of the clamping portion 412 is smaller than the width of the limiting hole 311, the clamping portion 412 can be clamped into the limiting hole 311 under the action of the first elastic member 42. Since the width of the clamping portion 412 is larger than the width of the clearance channel 313, the clamping portion 412 cannot slide from the limiting hole 311 into the clearance channel 313, thereby preventing the locking assembly 30 from switching to the locked state. Figure 5 and Figure 7 .

[0080] It should be noted that when it is necessary to release the restriction of the locking assembly 30 by the limit assembly 40, an active release method or a passive release method can be used. Among them, the active release method means that the limit assembly 40 can automatically release the restriction on the locking assembly 30, for example, after the adapter block 20 is removed from the installation slot 11, the limit assembly 40 is no longer stuck in the limit hole 311 through linkage. The passive release method means that an external force is used to release the restriction of the locking assembly 30 by the limit assembly 40, for example, the user applies a force to the limit assembly 40, and the limit assembly 40 is no longer stuck in the limit hole 311.

[0081] In one embodiment of the present application, please refer to Figures 4 to 6 The adapter block 20 is provided with a recess 22, and the recess 22 has a guide surface 221. The guide surface 221 is inclined relative to the sliding direction of the adapter block 20. The base 10 is provided with a through hole 15 connected to the mounting groove 11. One end of the limiting column 41 extends into the recess 22 through the through hole 15. When the adapter block 20 slides out of the mounting groove 11, the guide surface 221 can abut against the limiting column 41 and retract.

[0082] The through hole 15 passes through the bottom surface to communicate with the mounting groove 11, so that one end of the limiting column 41 can pass through the through hole 15 and extend into the recess 22. Figure 3 And such as Fig. 9 .

[0083] The two ends of the adapter block 20 along the second direction F2 are respectively a proximal end and a distal end. When the adapter block 20 is installed in the mounting groove 11, the proximal end is close to the first end 12, and the distal end is close to the second end 13. The recess 22 is arranged on the side of the adapter block 20 facing the bottom surface and is arranged close to the distal end. The guide surface 221 is a side surface of the recess 22 close to the distal end, and the distance between the guide surface 221 and the bottom surface gradually decreases along the first direction F1. In this way, when the adapter block 20 slides out along the second direction F2, the guide surface 221 can abut against the limit column 41, so that the limit column 41 gradually retreats into the through hole 15, so that the clamping portion 412 of the limit column 41 exits the limit hole 311, thereby releasing the restriction of the limit assembly 40 on the locking assembly 30, so that the locking assembly 30 can return to the locked state.

[0084] In the above technical solution, the guiding surface 221 cooperates with the limiting column 41 . After the adapter block 20 slides out of the installation slot 11 , the limiting assembly 40 automatically releases the restriction on the locking assembly 30 . No manual operation is required, and the use is convenient.

[0085] The quick-release mechanism 100 of the present application, when the adapter block 20 needs to be installed on the base 10, slide the adapter block 20 from the first end 12 into the installation groove 11 along the first direction F1. During the process of the adapter block 20 sliding into the installation groove 11, the adapter block 20 pushes the protrusion 323 to exit the installation groove 11. After the adapter block 20 slides into place, the protrusion 323 is automatically snapped into the groove 21 under the action of the third elastic member 34, so that the adapter block 20 is automatically locked in the installation groove 11.

[0086] When the adapter block 20 needs to be removed from the base 10, the user presses the push block 31 with one hand to make the push block 31 move along the second direction F2. When the push block 31 moves along the second direction F2, the slide block 32 is pushed to move along the third direction F3, so that the protrusion 323 on the slide block 32 gradually withdraws from the groove 21 on the adapter block 20; when the protrusion 323 completely withdraws from the groove 21, the locking assembly 30 is in an unlocked state. At this time, the limiting column 41 corresponds to the limiting hole 311, and the first elastic member 42 pushes the limiting column 41 to move in the direction of the adapter block 20, so that the clamping portion 412 is clamped into the limiting hole 311, so that the push block 31 cannot move along the first direction F1, that is, the push block 31 cannot be reset, and thus the slide block 32 cannot be The method is to move along the fourth direction F4 opposite to the third direction F3, so that the protrusion 323 and the groove 21 remain in a separated state. The user releases the force on the push block 31, and the locking assembly 30 can also remain in the unlocked state; gradually slide the adapter block 20 out of the installation groove 11 along the second direction F2. During this process, the guide surface 221 abuts against the column 411, so that the column 411 gradually retreats into the through hole 15, and the clamping portion 412 exits the limiting hole 311. At the moment when the clamping portion 412 exits the limiting hole 311, the push block 31 moves along the first direction F1 under the action of the second elastic member 33 until it returns to the initial position, and the slider 32 moves along the fourth direction F4 under the action of the third elastic member 34 until it returns to the initial position.

[0087] The quick release mechanism 100 further includes a sealing plate 50 . The sealing plate 50 is disposed on a side of the base 10 away from the adapter block 20 . The sealing plate 50 is used to seal the accommodating cavity 14 .

[0088] The quick release mechanism 100 provided in the embodiment of the present application can quickly lock the adapter block 20 in the installation slot 11, and can also achieve one-key unlocking, which is simple to operate and easy to use.

[0089] Please refer to Figure 1 The present application also provides a lamp, comprising a lamp body, a bracket 200 and a quick-release mechanism 100 according to any one of the above embodiments, wherein the lamp body is detachably connected to the bracket 200 via the quick-release mechanism 100.

[0090] Specifically in this embodiment, the lamp also includes a lamp housing 300, the lamp body is arranged in the lamp housing 300, the number of quick-release mechanisms 100 is two, the bases 10 of the two quick-release mechanisms 100 are respectively fixed on the outer walls on the opposite sides of the lamp housing 300, and the adapter blocks 20 of the two quick-release mechanisms 100 are respectively connected to the two ends of the bracket 200.
