[0003] Therefore, the prior art needs to be improved and developed. It should be noted that the above information disclosed in this section is only used to understand the background of the concept of the utility model, and therefore may contain information that does not constitute prior art. Utility Model Content

[0004] The purpose of the present application is to provide a quick-release structure for a film and television lamp, which can effectively solve the problem of inconvenience in installing or disassembling the film and television lamp due to the inconvenience in tightening or loosening the screws.

[0005] The present application provides a quick-release structure for a film and television lamp, which is used for quick installation or quick removal of the film and television lamp. The film and television lamp is provided with a protrusion, and at least one side of the protrusion is provided with a locking groove. The quick-release structure for the film and television lamp includes:

[0006] The card seat has a through hole and a protrusion slide groove for inserting the protrusion, and the through hole is perpendicular to the side wall of the protrusion slide groove;

[0007] The clamping shaft is slidably connected with the through hole and can be inserted into the locking groove on the protrusion located in the protrusion sliding groove through the through hole. A handle is fixed on the end of the clamping shaft away from the protrusion sliding groove.

[0008] The present application provides a quick-release structure for a film and television lamp, which can achieve quick installation or quick disassembly of the film and television lamp by using a handle to drive the card shaft to slide along the through hole toward or away from the protrusion slot. Since when installing or disassembling the film and television lamp, the present application only needs to use the handle to drive the card shaft to slide along the through hole toward and away from the protrusion slot, that is, the present application does not need to tighten or loosen the screws, so the present application can effectively solve the problem of inconvenience in installing or disassembling the film and television lamp due to the inconvenience in tightening or loosening the screws.

[0009] Furthermore, an elastic element placement groove is provided in the middle of the through hole, a convex edge is provided on the clamping shaft and is located in the elastic element placement groove, and the quick-release structure of the film and television lamp also includes a first elastic element, the first elastic element is located in the elastic element placement groove and is sleeved on the clamping shaft, and the two ends of the first elastic element respectively conflict with the convex edge and the inner wall of the elastic element placement groove.

[0010] Furthermore, the first elastic element is a spring.

[0011] Furthermore, locking grooves are provided on both sides of the same protrusion, elastic element placement grooves are provided on both sides of the protrusion sliding groove, and the number of the clamping shafts and the first elastic elements is the same as the number of the locking grooves.

[0012] Since locking grooves are provided on both sides of the same protrusion of this technical solution, and elastic element placement grooves are provided on both sides of the protrusion slide groove, this technical solution is equivalent to using two card shafts to lock the same protrusion, thereby effectively avoiding the situation where the protrusion cannot be locked due to insufficient force provided by the card shaft to the protrusion when only one card shaft is used to lock the same protrusion, and the film and television lamp can move relative to the bracket.

[0013] Furthermore, the protrusion sliding groove includes a contraction groove and a limiting groove which are connected to each other, the contraction groove contracts toward the limiting groove, and the limiting groove is connected to the through hole.

[0014] Since the bump slide groove of this technical solution includes a contraction groove and a limit groove that are interconnected, and the contraction groove is located above the limit groove and contracts toward the limit groove, when the bump is inserted into the bump slide groove, the contraction groove can guide the bump so that the bump can be smoothly inserted into the limit groove.

[0015] Furthermore, a second elastic element is installed on the protrusion sliding groove, and the direction of the elastic force provided by the second elastic element is perpendicular to the axial direction of the card shaft.

[0016] Furthermore, the second elastic element is a spring ball.

[0017] Furthermore, the card holder includes a base and a cover plate, the cover plate is detachably fixed to the base, and the protrusion slide groove is located on the base.

[0018] Furthermore, protrusions are provided on both sides of the film and television lamp, and the same film and television lamp can be quickly installed or disassembled through two symmetrically arranged sockets. The number of the sockets is 2n, where n is a positive integer greater than 1.

[0019] Furthermore, an unlocking groove is provided on the outer side wall of the card seat, and the unlocking groove is perpendicular to the sliding direction of the card shaft.

[0020] From the above, it can be seen that the utility model provides a quick-release structure for film and television lamps, which can achieve rapid installation or rapid disassembly of film and television lamps by using a handle to drive the card shaft to slide along the through hole toward or away from the protrusion slot. Since when installing or disassembling the film and television lamps, the application only needs to use the handle to drive the card shaft to slide along the through hole toward and away from the protrusion slot, that is, the application does not need to tighten or loosen the screws, so the application can effectively solve the problem of inconvenience in installing or disassembling film and television lamps due to the inconvenience in tightening or loosening the screws.

[0031] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples.

[0032] like Figures 1-6 As shown, the present application provides a quick-release structure for a film and television lamp, which is used for quickly installing or quickly removing a film and television lamp 1. The film and television lamp 1 is provided with a protrusion 3, and at least one side of the protrusion 3 is provided with a locking groove 4. The quick-release structure for the film and television lamp includes:

[0033] The card holder 5 has a through hole 14 and a bump slot 6 for inserting the bump 3, and the through hole 14 is perpendicular to the side wall of the bump slot;

[0034] The clamping shaft 7 is slidably connected to the through hole 14 and can be inserted into the locking groove 4 on the protrusion 3 located in the protrusion groove 6 through the through hole 14. A handle 8 is fixed to the end of the clamping shaft away from the protrusion groove 6.

[0035] The present application provides a quick-release structure for a film and television lamp that can quickly install the film and television lamp 1 on an object to be fixed (an object on which the film and television lamp 1 needs to be installed, such as a bracket 2). The film and television lamp 1 of this embodiment is preferably installed on the bracket 2. The film and television lamp 1 of this embodiment can be a complex composed of a light-emitting element (such as an LED lamp), a soft light panel, and a heat dissipation structure. A protrusion 3 is provided on the film and television lamp 1, and a locking groove 4 is provided on at least one side of the protrusion 3. The quick-release structure of the film and television lamp in this embodiment includes a card seat 5 and a card shaft 7. The number of the card seats 5 is greater than or equal to the number of the protrusions 3. The number of the card seats 5 in this embodiment is preferably equal to the number of the protrusions 3. The card seat 5 in this embodiment is preferably installed on the bracket 2. The card seat 5 has a through hole 14 and a protrusion slide 6 for inserting the protrusion 3. The through hole 14 in this embodiment is perpendicular to the side wall of the protrusion slide 6 and is connected to the protrusion slide 6. The number of the card shaft 7 in this embodiment is preferably the same as the number of the locking groove 4. The card shaft 7 is slidably connected to the through hole 14. The card shaft 7 can be inserted into the locking groove 4 on the protrusion 3 located in the protrusion slide 6 through the through hole 14. Specifically, when the card shaft 7 is inserted into the protrusion located in the protrusion slide 6 3, the card shaft 7 contacts the side wall of the locking groove 4. At this time, even if the film and television lamp 1 is subjected to a vertical upward external force, the position of the protrusion 3 will not change. That is, when the card shaft 7 is inserted into the locking groove 4 on the protrusion 3 located in the protrusion slide groove 6, the film and television lamp 1 is locked (the film and television lamp 1 cannot move relative to the card base 5), thereby realizing rapid installation of the film and television lamp 1. When the card shaft 7 is moved out of the locking groove 4, if the film and television lamp 1 is subjected to a vertical upward external force, the position of the protrusion 3 can change, that is, after the card shaft 7 is moved out of the locking groove 4, the film and television lamp 1 is unlocked (the film and television lamp 1 can move relative to the card base 5), thereby realizing rapid disassembly of the film and television lamp 1. In this embodiment, a handle 8 is fixed to the end of the card shaft 7 away from the protrusion slot 6. That is, in this embodiment, the handle 8 can be used to drive the card shaft 7 to slide along the through hole 14 or to drive the card shaft 7 to rotate. Specifically, in this embodiment, the handle 8 and the card shaft 7 can be fixed by making the handle 8 contact the outer wall of the card base 5. This prevents the card shaft 7 that has been moved out of the locking slot 4 from being accidentally inserted into the locking slot 4 when the film and television lamp 1 needs to be disassembled. The specific process of installing the film and television lamp 1 in this embodiment can be as follows: using the handle 8 to drive the card shaft 7 to slide along the through hole 14 away from the protrusion slot 6 to remove the card shaft 7 from the protrusion slot 6; driving the handle 8 to rotate so that the handle 8 contacts the outer wall of the card base 5; inserting the protrusion 3 of the film and television lamp 1 into the protrusion slot 6; using the handle 8 to drive the card shaft 7 to slide along the through hole 14 toward the protrusion slot 6, so that the card shaft 7 is inserted from the through hole 14 into the locking slot 4 on the protrusion 3 located in the protrusion slot 6 and the film and television lamp 1 is locked in the protrusion slot 6.The specific process for disassembling the film and television lamp 1 in this embodiment can be as follows: using the handle 8 to drive the card shaft 7 to slide along the through hole 14 away from the protrusion slot 6 to remove the card shaft 7 from the locking slot 4; driving the handle 8 to rotate so that the handle 8 contacts the outer wall of the card base 5; moving the protrusion 3 of the film and television lamp 1 out of the protrusion slot 6; driving the handle 8 to rotate to release the contact between the handle 8 and the outer wall of the card base 5, and using the handle 8 to drive the card shaft 7 to slide along the through hole 14 toward the protrusion slot 6 to reset the card shaft 7 (so that the card shaft 7 is inserted into the protrusion slot 6). Preferably, the film and television lamp 1 in this embodiment is provided with protrusions 3 on both sides. This embodiment is equivalent to fixing the film and television lamp 1 by both sides, thereby effectively improving the stability of the film and television lamp 1.

[0036] The present application provides a quick-release structure for a film and television lamp, which can achieve rapid installation or removal of the film and television lamp 1 by using a handle 8 to drive the card shaft 7 to slide along the through hole 14 toward or away from the protruding block groove 6. Since, when installing or removing the film and television lamp 1, the present application only requires using the handle 8 to drive the card shaft 7 to slide along the through hole 14 toward or away from the protruding block groove 6, that is, the present application does not require tightening or loosening screws, and thus the present application can effectively solve the problem of inconvenient installation or removal of the film and television lamp 1 due to the inconvenience of tightening or loosening screws. In addition, since the card shaft 7 cannot slide along the through hole 14 toward the protruding block groove 6 when the handle 8 contacts the outer wall of the card holder 5, the present application can complete the installation and removal of the film and television lamp 1 by a single person.

[0037] In some embodiments, an elastic element placement groove 10 is provided in the middle of the through hole 14, a convex edge 11 is provided on the card shaft 7 and is located in the elastic element placement groove 10, and the quick-release structure of the film and television lamp also includes a first elastic element 12, the first elastic element 12 is located in the elastic element placement groove 10 and is sleeved on the card shaft 7, and the two ends of the first elastic element 12 respectively conflict with the convex edge 11 and the inner wall of the elastic element placement groove 10. The first elastic element 12 is located in the elastic element placement groove 10 and is sleeved on the card shaft 7, and the two ends of the first elastic element 12 respectively conflict with the convex edge 11 and the inner wall of the elastic element placement groove 10. Specifically, after the card shaft 7 is inserted into the locking groove 4 or when the protrusion 3 is not inserted into the protrusion slot 6, the first elastic element 12 does not deform, and when the protrusion 3 is inserted into the protrusion slot 6, the first elastic element 12 deforms, and the first elastic element 12 provides an elastic force for the card shaft 7 toward the protrusion slot 6, in the locking groove 4 When facing the through hole 14, the elastic force drives the card shaft 7 to slide along the through hole 14 toward the protrusion groove 6, so that the card shaft 7 is inserted from the through hole 14 into the locking groove 4 on the protrusion 3 located in the protrusion groove 6. When the handle 8 conflicts with the outer wall of the card seat 5, the first elastic element 12 is deformed. The first elastic element 12 provides an elastic force toward the protrusion groove 6 for the card shaft 7. When the handle 8 is no longer in conflict with the outer wall of the card seat 5, the elastic force drives the card shaft 7 to slide along the through hole 14 toward the protrusion groove 6, so that the card shaft 7 is reset.

[0038] In some embodiments, the first elastic element 12 is a spring. This embodiment is equivalent to using a spring as the first elastic element 12. Since springs have the advantages of strong stability and low price, this embodiment can effectively improve the stability of the quick-release structure of the film and television lamp and reduce the production cost of the quick-release structure of the film and television lamp.

[0039] In some embodiments, as Figure 7 As shown, locking grooves 4 are provided on both sides of the same protrusion 3, elastic element placement grooves 10 are provided on both sides of the protrusion chute 6, and the number of the clamping shafts 7 and the first elastic elements 12 is the same as the number of the locking grooves 4. Since the locking grooves 4 are provided on both sides of the same protrusion 3 in this embodiment, and elastic element placement grooves 10 are provided on both sides of the protrusion chute 6, this embodiment is equivalent to using two clamping shafts 7 to lock the same protrusion 3, thereby effectively avoiding the situation where the clamping shaft 7 cannot lock the protrusion 3 due to insufficient force provided by the clamping shaft 7 to the protrusion 3 when only one clamping shaft 7 is used to lock the same protrusion 3, and the film and television lamp 1 can move relative to the bracket 2.

[0040] In some embodiments, the projection chute 6 includes a contraction groove 61 and a limiting groove 62 that are interconnected. The contraction groove 61 contracts toward the limiting groove 62, and the limiting groove 62 is connected to the through hole 14. The limiting groove 62 of this embodiment can fit with the projection 3. Since the projection chute 6 of this embodiment includes a contraction groove 61 and a limiting groove 62 that are interconnected, and the contraction groove 61 contracts toward the limiting groove 62, when the projection 3 is inserted into the projection chute 6, the contraction groove 61 can guide the projection 3, so that the projection 3 can be smoothly inserted into the limiting groove 62.

[0041] In some embodiments, a second elastic element 13 is mounted on the projection chute 6. The direction of the elastic force provided by the second elastic element 13 is perpendicular to the axial direction of the card shaft 7. The second elastic element 13 of this embodiment is located on the side of the projection chute 6 away from the cover plate 52. Specifically, when the projection 3 is not inserted into the projection chute 6, the second elastic element 13 does not deform. However, after the projection 3 is inserted into the projection chute 6, the second elastic element 13 deforms, providing the projection 3 with an elastic force perpendicular to the axial direction of the card shaft 7. This elastic force can press the projection 3 tightly to prevent the projection 3 from shaking in the projection chute 6.

[0042] In some embodiments, the second elastic element 13 is a spring ball. The spring ball of this embodiment can be an existing device. Specifically, the spring ball of this embodiment includes a mounting seat, a spring, and a ball. One side of the mounting seat is provided with an opening, and the ends of the spring are connected to the mounting seat and the ball, respectively. The cross-sectional area of ​​the opening is smaller than that of the ball, meaning that the ball can partially extend out of the mounting seat through the opening. Preferably, the protrusion 3 of this embodiment is provided with a retaining groove 15. After the protrusion 3 is inserted into the protrusion chute 6, the spring ball engages the retaining groove 15, thereby quickly securing the protrusion 3.

[0043] In some embodiments, the card holder 5 includes a base 51 and a cover 52. The cover 52 is detachably fixed to the base 51, and the protrusion slot 6 is located on the base 51. The cover 52 of this embodiment can be detachably fixed to the base 51 by screw locking or snap connection. The protrusion slot 6, through hole 14, and elastic element placement groove 10 of this embodiment are all located on the base 51. When the first elastic element 12 needs to be replaced, this embodiment requires removing the cover 52.

[0044] In some embodiments, as Figure 8 As shown, a projection 3 is provided on both sides of the film and television lamp 1. The same film and television lamp 1 is quickly installed or removed via two symmetrically arranged holders 5. The number of holders 5 is 2n, where n is a positive integer greater than 1. Since the number of holders 5 in this embodiment is 2n, and n is a positive integer greater than 1, this embodiment is equivalent to being able to simultaneously lock multiple film and television lamps 1 on the bracket 2 to meet different usage requirements.

[0045] In some embodiments, an unlocking groove 9 is provided on the outer wall of the card base 5, and the unlocking groove 9 is perpendicular to the sliding direction of the card shaft 7. Since the unlocking groove 9 is provided on the outer wall of the card base 5 and the unlocking groove 9 of this embodiment is perpendicular to the sliding direction of the card shaft 7, after the card shaft 7 is pulled out of the locking groove 4 using the handle 8, this embodiment only needs to rotate the handle 8 to make the handle 8 interfere with the unlocking groove 9. In addition, the unlocking groove 9 can prevent the card shaft 7 from being reinserted into the locking groove 4 under the action of the first elastic element 12 due to the handle 8 accidentally deflecting after the card shaft 7 is removed from the locking groove 4.

[0046] From the above, it can be seen that the utility model provides a quick-release structure for a film and television lamp, which can realize the quick installation or quick disassembly of the film and television lamp 1 by using the handle 8 to drive the card shaft 7 to slide along the through hole 14 toward or away from the protrusion slide groove 6. Since when installing or disassembling the film and television lamp 1, the application only needs to use the handle 8 to drive the card shaft 7 to slide along the through hole 14 toward and away from the protrusion slide groove 6, that is, the application does not need to tighten or loosen the screws, so the application can effectively solve the problem of inconvenience in installing or disassembling the film and television lamp 1 due to the inconvenience in tightening or loosening the screws.
