[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0049] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0050] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0051] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0052] Please refer to Figures 1 to 3, the quick release device provided by the embodiment of the present application is now described. The quick release device is installed on the support rod 100. The quick release device includes a quick release part 1, a quick release seat 2, a limiter 3, an unlocking button 4 and a first elastic member 5. The quick release seat 2 is provided with a limiter installation groove 22, and one side of the limiter installation groove 22 is provided with an insertion port 220. The quick release part 1 can be inserted into the limiter installation groove 22 from the insertion port 220 along the X direction, and the limiter installation groove 22 can limit the movement of the quick release part 1 in the Y direction and the Z direction. The quick release part 1 is provided with a limiter groove 10, and the limiter 3 is slidably arranged on the quick release seat 2 in the Y direction. When the limiter 3 slides to the limit state, the limiter 3 can at least partially be inserted into the limiter groove 10 to limit the movement of the quick release part 1 in the X direction; when the limiter 3 slides to the unlocking state, the limiter 3 is separated from the limiter groove 10. The unlocking button 4 is connected to the limiter 3, and the unlocking button 4 is at least partially located outside the quick release seat 2. The first elastic member 5 is in contact between the quick release seat 2 and the unlocking button 4 , and is used to drive the limiting member 3 to return from the unlocking state to the limiting state.

[0053] Assembly process: The quick release part 1 is inserted from the insertion port 220 into the limiting installation slot 22 of the quick release seat 2 along the X direction. During the insertion process, the quick release part 1 pushes the limiting part 3 to move from the limiting state to the unlocking state (that is, out of the limiting installation slot 22). When the quick release part 1 is in place in the limiting installation slot 22, the limiting part 3 automatically returns to the limiting state under the action of the first elastic part 5, thereby limiting the movement of the quick release part 1 in the X direction. Since the limiting installation slot 22 limits the quick release part 1 in the Y direction and the Z direction, the quick release part 1 is locked on the quick release seat 2 to achieve assembly.

[0054] Disassembly process: manually press the unlock button 4, the unlock button 4 pushes the limit member to switch from the limit state to the unlock state, and at the same time uses the lock block 60 to limit the movement of the limit member 3 and keep it in the unlock state. The limit member 3 in the unlocked state is separated from the limit installation groove 22, thereby releasing the restriction of the limit member 3 on the movement of the quick release member 1 along the X direction, so that the quick release member 1 can slide out of the limit installation groove 22 along the X direction to achieve disassembly.

[0055] By connecting the quick-release part 1 with the device to be installed and installing the quick-release seat 2 on the support rod 100, the device to be installed and the support rod 100 can be quickly disassembled and assembled. For example, the quick-release device provided by the present application is applied to the disassembly and assembly of a lamp and a support rod 100, the lamp is installed on the quick-release part 1, and the quick-release seat 2 is installed on the support rod 100. When in use, the quick-release part 1 and the quick-release seat 2 cooperate to achieve the quick disassembly and assembly of the lamp and the support rod 100.

[0056] Compared with the prior art, for the quick-release device provided in this application, assuming that the unlocking button 4 is accidentally pressed during daily use, the limiting member 3 is in an unlocked state and loses the limiting effect on the quick-release member 1. Since the first elastic member 5 is squeezed when the unlocking button 4 is pressed, when the unlocking button 4 is released, the first elastic member 5 exerts a force on the unlocking button 4 to drive the unlocking button 4 to reset. Furthermore, the unlocking button 4 drives the limiting member 3 to reset, that is, the limiting member 3 is timely restored to the limiting state, thereby avoiding the accidental detachment of the quick-release member 1 from the quick-release base 2 due to accidental contact with the unlocking button 4 and improving the use safety of the quick-release device.

[0057] For convenience of description, it is defined that the X direction is specifically the left-right direction, the Y direction is specifically the up-down direction, and the Z direction is specifically the front-back direction, and the corresponding orientations are specifically the left side, the right side, the upper side, the lower side, the front side, and the rear side.

[0058] In another embodiment of the present application, please refer to Figure 4 , the cross-sectional shape of the quick-release member 1 in the Y direction is square, and at least one pair of opposite sides of the quick-release member 1 is provided with a limiting groove 10. Thus, the quick-release member 1 can be inserted into the quick-release base 2 at at least two angles (such as 0 degrees and 180 degrees), so that the devices on the quick-release member 1 can be installed at different angles. Of course, the cross-sectional shape of the quick-release member 1 in the Y direction can also be rectangular, and the quick-release member 1 can be inserted into the quick-release base 2 at two angles.

[0059] Furthermore, the cross-sectional shape of the quick-release member 1 in the Y direction is square, and limiting grooves 10 are provided on all four sides of the quick-release member 1, so that the quick-release member 1 can be inserted into the quick-release base 2 from four different angles.

[0060] In another embodiment of the present application, please refer to Figure 3 and Figure 4 , the shape of the limiting installation groove 22 is in the shape of a dovetail groove. Thus, when the quick-release member 1 is inserted into the limiting installation groove 22, the limiting installation groove 22 limits the quick-release member 1 in the Y direction and the Z direction.

[0061] In another embodiment of the present application, please continue to refer to Figure 3 and Figure 4 , a positioning block 23 is provided on one side of the quick-release base 2 away from the insertion port 220, and the positioning block 23 is used to limit the position of the limiting groove 10 in the limiting installation groove 22. Thus, it is avoided that the quick-release member 1 is inserted into the limiting installation groove 22 from the insertion port 220 and then pulled out from the other side of the limiting installation groove 22, and at the same time, it is ensured that the position of the limiting groove 10 in the limiting installation groove 22 can coincide with the limiting member 3.

[0062] In another embodiment of the present application, please continue to refer to Figure 3 and Figure 4, limiting slots 10 are provided on all four sides of the quick-release part 1. When the quick-release part 1 is inserted into the limiting installation slot 22, the positioning block 23 can be inserted into one of the corresponding limiting slots 10.

[0063] In another embodiment of the present application, refer to Figure 2 and Figure 3 , the quick-release seat 2 is of a housing structure, and the limiting part 3 and the first elastic part 5 are arranged inside the quick-release seat 2. Accommodating the limiting part 3 and the first elastic part 5 inside the quick-release seat 2 makes the structure more compact and can play a role in limiting and protecting the limiting part 3 and the first elastic part 5.

[0064] In another embodiment of the present application, a through hole is provided on the quick-release seat 2. One end of the unlocking button 4 extends into the quick-release seat 2 through the through hole and is connected to the limiting part 3, and the other end of the unlocking button 4 is located outside the quick-release seat 2.

[0065] In another embodiment of the present application, refer to Figure 3 and Figure 5 , a card slot 40 is provided on the unlocking button 4, and a clamping block 311 is provided on the limiting part 3. The clamping block 311 can be inserted into the card slot 40 along the X direction or the Z direction, and the clamping block 311 and the card slot 40 are limited in movement in the Y direction, so that the limiting part 3 and the unlocking button 4 are hooked with each other in the Y direction, and further the limiting part 3 and the unlocking button 4 can move synchronously along the Y direction.

[0066] Specifically, the card slots 40 are provided on both sides of the unlocking button 4, a U-shaped hole 310 is provided at the bottom of the limiting part 3, and the clamping blocks 311 are provided on the two side walls of the U-shaped hole 310. The limiting part 3 sleeved the unlocking button 4 through the U-shaped hole 310, and the two clamping blocks 311 are respectively inserted into the card slots 40 correspondingly.

[0067] In another embodiment of the present application, refer to Figure 3 and Figure 5 , a first installation slot 41 for inserting the first elastic part 5 is provided at the end of the unlocking button 4 located inside the quick-release seat 2. One end of the first elastic part 5 is connected to the quick-release seat 2, and the other end of the first elastic part 5 is installed in the first installation slot 41. The first installation slot 41 can play a guiding role for the first elastic part 5.

[0068] In another embodiment of the present application, refer to Figure 2 and Figure 3, the quick-release seat 2 includes a seat body 20 and a cover body 21. The seat body 20 and the cover body 21 are covered to form a housing structure, which can accommodate the limiting member 3 and the first elastic member 5. A guiding groove 24 is provided on the inner wall of the seat body 20 for guiding the movement of the limiting member 3 in the Y direction. An installation block 25 extending towards the cover body 21 in the Z direction is also provided on the inner wall of the seat body 20. The installation block 25 is used for one end of the first elastic member 5 to abut against or be fixed to the quick-release seat 2. Therefore, the first elastic member 5 abuts between the installation block 25 and the groove wall of the first installation groove 41.

[0069] In another embodiment of the present application, refer to Figure 5 and Figure 6 , a limiting hole 27 is provided on the quick-release seat 2. The limiting hole 27 communicates the inside of the quick-release seat 2 with the limiting installation groove 22. When the limiting member 3 is in the limiting state, the limiting member 3 can be located in the limiting installation groove 22 through the limiting hole 27.

[0070] In another embodiment of the present application, refer to Figure 4 , a pushing inclined surface 300 for pushing and cooperating with the quick-release member 1 is provided on the limiting member 3. By using the pushing inclined surface 300, during the assembly process, the operator only needs to push the quick-release member 1 to smoothly push the limiting member 3 to the unlocked state, so as to facilitate the installation of the quick-release member 1 on the quick-release seat 2.

[0071] In order to enable the limiting member 3 to remain in the unlocked state during the process of the quick-release member 1 being pulled out from the quick-release seat 2, so as to facilitate the operator to pull out the quick-release member 1. In another embodiment of the present application, please refer to Figures 7 to 8 , the quick-release device further includes an unlocking and holding assembly 6. When the limiting member 3 is in the unlocked state, the unlocking and holding assembly 6 can abut against the limiting member 3 in the Y direction to keep the limiting member 3 in the unlocked state.

[0072] In another embodiment of the present application, please refer to Figures 7 to 8 , a locking groove 312 is provided on the limiting member 3. The unlocking and holding assembly 6 includes a locking block 60 and a second elastic member 61. The locking block 60 is slidably arranged on the quick-release seat 2 in the Z direction. When the limiting member 3 is in the unlocked state, the locking block 60 can be inserted into the locking groove 312 in the Z direction. The second elastic member 61 abuts between the locking block 60 and the quick-release seat 2, and the second elastic member 61 is used to drive the locking block 60 to insert into the locking groove 312.

[0073] During the disassembly process, after manually pressing the unlocking button 4 and pushing the limiting member 3 to the unlocked state, the locking block 60 is driven by the second elastic member 61 to be inserted into the locking groove 312 in the Z direction, thereby restricting the limiting member 3 from sliding in the Y direction to the limiting state and keeping the limiting member 3 in the unlocked state, so as to facilitate the extraction of the quick-release member 1 from the quick-release seat 2.

[0074] In another embodiment of the present application, please refer toFigures 8 to 9 The lock block 60 is a cylindrical structure. At one end of the lock block 60 facing away from the quick-release member 1, a second installation groove 601 is provided. The second elastic member 61 is installed in the second installation groove 601. One end of the second elastic member 61 abuts or is fixedly connected to the groove wall of the second installation groove 601, and the other end of the second elastic member 61 abuts or is fixedly connected to the inner cavity wall of the accommodating cavity of the quick-release seat 2. The second installation groove 601 can play a guiding role for the second elastic member 61.

[0075] In another embodiment of the present application, please refer to Figure 7 , Figure 8 and Figure 10 , the limiting member 3 includes a limiting portion 30 and a main body portion 31. The limiting portion 30 is connected to the end of the main body portion 31. The limiting portion 30 is the part located in the limiting installation groove 22 (refer to Figure 4 ) in the limiting state as described above. The abutting inclined surface 300 is formed on the limiting portion 30. The main body portion 31 has a U-shaped structure and has the aforementioned U-shaped hole 310. The locking block 311 is provided at the end of the main body portion 31 far from the limiting portion 30.

[0076] The middle position of the U-shaped hole 310 of the main body portion 31 is for the lock block 60 to pass through, and the U-shaped hole 310 extends a certain length in the Y direction, so that the limiting member 3 will not interfere with the lock block 60 when moving between the limiting state and the unlocking state. The lock groove 312 is formed by extending and opening from the U-shaped hole 310 to the two side walls of the main body portion 31. A flange 600 is provided on the lock block 60. The flange 600 is arranged around the side circumference of the lock block 60. The flange 600 can be snapped into the lock groove 312. When the limiting member 3 is in the limiting state, the flange 600 is abutted against the end wall of the main body portion 31. When the limiting member 3 is in the unlocking state, since the lock groove 312 can allow the flange 600 to be snapped in, the lock block 60 moves forward under the action of the second elastic member 61, and the flange 600 is snapped into the lock groove 312, so that the lock groove 312 and the lock block 60 are restricted from moving relative to each other in the Y direction.

[0077] Since the above-mentioned lock block 60 can play a holding role when the limiting member 3 is in the unlocking state, in order to release the holding effect of the lock block 60 on the limiting member 3 after the operator pulls out the quick-release member 1, so that the limiting member 3 can automatically return to the limiting state. In another embodiment of the present application, please refer to Figures 6 to 8 , a reset hole 26 is provided on the quick-release seat 2, and a reset groove 11 is provided on the quick-release member 1. When the quick-release member 1 is inserted into the limiting installation groove 22, the reset hole 26 communicates with the reset groove 11. When the lock block 60 is inserted into the lock groove 312, the lock block 60 passes through the reset hole 26 along the Z direction and extends into the reset groove 11. That is, the front end of the lock block 60 sequentially passes through the U-shaped hole 310 and the reset hole 26 along the Z direction and extends into the reset groove 11.

[0078] Supplementary description: When the limiting member 3 is in the limiting state, the locking block 60 sequentially passes through the U-shaped hole 310 of the limiting member 3 and the reset hole 26 of the quick-release seat 2, but the length is not enough to extend into the reset groove 11 of the quick-release member 1. When the limiting member 3 is in the unlocking state, since the locking groove 312 on the limiting member 3 allows the flange 600 of the locking block 60 to be inserted, the locking block 60 moves a certain distance in the direction close to the quick-release member 1 (this distance is the length of the locking groove 312 along the Z direction). At this time, the front end of the locking block 60 sequentially passes through the U-shaped hole 310 of the limiting member 3 and the reset hole 26 of the quick-release seat 2 and extends into the reset groove 11 of the quick-release member 1.

[0079] During disassembly, since the limiting member 3 is in the unlocking state and the locking block 60 can extend into the reset groove 11 of the quick-release member 1, when the quick-release member 1 is withdrawn from the limiting installation groove 22, the notch of the reset groove 11 will push the locking block 60 out of the reset groove 11. At the same time, the flange 600 of the locking block 60 is withdrawn from the locking groove 312. Therefore, the locking block 60 loses its restrictive effect on the limiting member 3 in the Y direction, so that the limiting member 3 can automatically return to the limiting state when the quick-release member 1 is withdrawn, realizing the automatic reset function.

[0080] In order to enable the limiting member 3 to achieve the automatic reset function after disassembly, it is necessary to ensure that the limiting portion 30 of the limiting member 3 moves ahead of the locking block 60 during the process of the quick-release member 1 being withdrawn from the limiting installation groove 22. That is to say, when the limiting member 3 can move from the unlocking state to the limiting state, the locking block 60 is still abutted by the end face of the quick-release member 1 and the flange 600 cannot be inserted into the locking groove 312. In another embodiment of the present application, please refer to Figures 7 to 8 , let the angle on the limiting member 3 that can abut against the quick-release member 1 be the abutting angle 301, and let the side of the locking block 60 close to the insertion port 220 be the abutting side 604. The abutting side 604 is closer to the insertion port 220 in the X direction than the abutting angle 301.

[0081] During the process of the quick-release member 1 being withdrawn from the limiting installation groove 22 (refer to Figure 4 ), since the abutting side 604 of the locking block 60 is closer to the insertion port 220, when the side of the quick-release member 1 away from the insertion port 220 moves to the abutting angle 301, the limiting member 3 can start to move in the direction of the limiting state under the action of the first elastic member 5, and at least the abutting side 604 of the locking block 60 is still abutted by the back surface of the quick-release member 1 and cannot be inserted into the locking groove 312. Therefore, the locking block 60 cannot limit the movement of the limiting member 3, and further the limiting member 3 can achieve automatic reset after the quick-release member 1 is withdrawn.

[0082] In order to ensure that the quick-release member 1 can smoothly push the locking block 60, in another embodiment of the present application, the notch of the reset groove 11 of the quick-release member 1 is chamfered.

[0083] During daily use, if the unlocking button 4 is accidentally pressed, it will cause the locking block 60 to hold the limiting member 3 in the unlocked state. Generally speaking, at this time, it is necessary to use the quick-release member 1 to extract it from the quick-release seat 2 so that the locking block 60 exits the locking groove 312, and then the limiting member 3 returns to the limiting state.

[0084] The quick-release device provided by the embodiment of the present application is to avoid the above unnecessary operations caused by accidentally touching the unlocking button 4. In another embodiment of the present application, please refer to Figure 8 and Figure 11 , the quick-release device includes a control component 7, and the control component 7 is used to make the locking block 60 exit the locking groove 312 and limit the locking block 60 from inserting into the locking groove 312.

[0085] During daily use, the control component 7 restricts the locking block 60 from inserting into the locking groove 312. At this time, no matter how the unlocking button 4 is pressed, the unlocking button 4 can be reset in time under the action of the first elastic member 5, that is, the limiting member 3 can return to the limiting state in time. Even if the locking block 60 is not restricted from inserting into the locking groove 312 by the control component 7, when the unlocking button 4 is accidentally pressed and the locking block 60 inserts into the locking groove 312, the control component 7 can also make the locking block 60 exit the locking groove 312.

[0086] Specifically, in another embodiment of the present application, please refer to Figure 8 and Figure 11 , the control component 7 includes a pull rod 70 and a fixing member. One end of the pull rod 70 is movably inserted through the support rod 100 and the quick-release seat 2 along the Z direction and is connected to the locking block 60, and the other end of the pull rod 70 is located on the side of the support rod 100 away from the quick-release seat 2. The fixing member is connected to the pull rod 70 and the support rod 100, and the fixing member can restrict the pull rod 70 from moving along the Z direction toward the limiting member 3.

[0087] When the unlocking button 4 is accidentally pressed to move the limiting member 3 to the unlocked state, the pull rod 70 is pulled in the direction of extracting the quick-release seat 2, and the pull rod 70 drives the locking block 60 to move synchronously, so that the flange 600 of the locking block 60 disengages from the locking groove 312, and the limiting member 3 is reset to the limiting state under the action of the first elastic member 5.

[0088] In addition, after pulling the pull rod 70 to make the locking block 60 exit the locking groove 312, the fixing member is used to restrict the pull rod 70 from moving along the Z direction toward the limiting member 3. This setting can ensure the assembly reliability and safety of the quick-release device during daily use. For example: without disassembly, by pulling the pull rod 70 so that the locking block 60 cannot reach the position of the locking groove 312, and fixing the pull rod 70 through the fixing member, so that no matter how the unlocking button 4 is pressed, the limiting member 3 can be automatically reset under the action of the first elastic member 5.

[0089] Specifically, in another embodiment of the present application, please refer to Figure 8and Figure 11 The support rod 100 is provided with a rectangular hole 1000, and the pull rod 70 has a rectangular section 700 for passing through and mating with the rectangular hole 1000. The fixing member is a knob 71. One end of the pull rod 70 away from the lock block 60 is provided with a threaded section 701. The knob 71 is threadedly connected to the threaded section 701, and the knob 71 is abutted against the side of the support rod 100 away from the quick-release base 2. During installation, the quick-release base 2 is placed on one side of the support rod 100, the pull rod 70 passes through the rectangular hole 1000, and the knob 71 is screwed tightly on the other side of the support rod 100. By rotating the knob 71, since the rectangular section 700 of the pull rod 70 cooperates with the rectangular hole 1000 of the support rod 100 to limit the rotation of the pull rod 70, the knob 71 can move on the threaded section 701 to adjust the distance that the pull rod 70 can extend into the quick-release base 2, so as to control whether the lock block 60 can be inserted into the lock groove 312 to limit the limiting member 3.

[0090] In another embodiment of the present application, please refer to Figure 3 and Figure 11 One end of the pull rod 70 away from the threaded section 701 is connected with a first screw 72. An abutting hole 602 is formed in the lock block 60. The rod portion of the first screw 72 can pass through the abutting hole 602 and be connected to the pull rod 70. The cap portion of the first screw 72 is abutted outside the lock block 60, so that the pull rod 70 abuts against the lock block 60. When the pull rod 70 moves in the Z direction away from the limiting member 3, the cap portion of the first screw 72 pushes the lock block 60 to move together.

[0091] In another embodiment of the present application, please refer to Figure 9 and Figure 11 One end of the lock block 60 close to the quick-release member 1 is provided with a displacement groove 603. The displacement groove 603 is communicated with the abutting hole 602, and the displacement groove 603 can allow the cap portion of the first screw 72 to pass through. Therefore, the rod portion of the first screw 72 passes through the displacement groove 603 and the abutting hole 602 in sequence and is connected to the pull rod 70, and the cap portion of the first screw 72 is located in the displacement groove 603. By providing this structure, when the distance that the pull rod 70 extends into the quick-release base 2 is increased, the first screw 72 will not protrude outside the lock block 60, thereby avoiding interference between the first screw 72 and the quick-release member 1 when the quick-release member 1 is pulled out.

[0092] In another embodiment of the present application, please refer to Figure 11 One end of the pull rod 70 provided with the threaded section 701 is connected with a second screw 73, and the second screw 73 is used to limit the knob 71 from detaching from the pull rod 70.

[0093] Please refer to Figure 1 The present application further provides a lighting device, which includes a lamp (not shown in the figure), a support rod 100 and the quick-release device provided by the embodiment of the present application. The lamp is connected to the quick-release member 1, and the support rod 100 is connected to the quick-release base 2.

[0094] The lighting device provided by this application adopts the quick-release device provided by the embodiments of this application, which can achieve the quick and convenient installation of the lamp and the support rod 100, and the assembly is more reliable and safe.

[0095] In another embodiment of this application, refer to Figure 3 and Figure 11 , the cover 21 of the quick-release base 2 is provided with a plug rod 28, and the support rod 100 is provided with a slot 1001. The plug rod 28 can be inserted into the slot 1001 along the Z direction. In some other embodiments, the cover 21 of the quick-release base 2 is provided with a slot 1001, and the support rod 100 is provided with a plug rod 28. The plug rod 28 can be inserted into the slot 1001 along the Z direction. Through the cooperation of the slot 1001 and the plug rod 28, the assembly stability of the quick-release base 2 and the support rod 100 can be improved.
