[0019] The locking piece is connected to the interface portion and is telescopically disposed in the inlet section;
[0020] Wherein, when the bayonet enters the entrance section, the locking piece can extend out of the entrance section, and after the bayonet enters the fastening section, the locking piece can at least partially retract into the entrance section to prevent the bayonet from detaching from the fastening section.
[0021] In some embodiments, the locking member includes a base, a locking portion, and an unlocking portion;
[0022] The base is arranged at the rear side of the interface portion along the axial direction and connected to the interface portion, and the base can move relative to the interface portion along the extension direction of the locking element;

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.
[0045] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0048] In different usage scenarios, photographic lights are used with different optical accessories to change the angle and direction of the light they emit. Optical accessories include but are not limited to reflectors, diffusers, snoots, Fresnel lenses, etc., which can adjust the nature, direction, range, etc. of the light.
[0049] Usually, a photographic light is installed by docking with the bayonet of an optical accessory through a mechanical interface. However, in the related art, after the mechanical interface and the bayonet are installed, the connection between the two is still relatively loose, which easily leads to a greater probability of the optical accessory shaking when the optical accessory is heavy, resulting in poor lighting and fill-in effects of the photographic light equipped with the optical accessory, greatly affecting the user experience.
[0050] To solve the above problems, please refer to Figure 1 The present application proposes a photography light 100, which is configured to emit light and is used to be installed with an optical accessory (not shown in the figure) so that the light can pass through the optical accessory and then be emitted to the outside to achieve lighting, fill light and other effects.
[0051] Please refer to Figure 1-Figure 4 In the embodiment of the present application, the photographic light 100 includes a lamp housing 10 and a fastening assembly 20. The lamp housing 10 serves as a carrier of the photographic light 100 and is used for installing various components of the photographic light 100, such as light source components, heat sink components, power supply components and other components. Among them, the shape of the lamp housing 10 can be roughly rectangular, so that the shape is relatively regular and easy to process and manufacture. Of course, in other embodiments, the shape of the lamp housing 10 can also be roughly cylindrical, etc. The lamp housing 10 can be a combination of sheet metal and plastic parts, so as to have the advantage of light weight on the basis of high strength. Of course, the present embodiment is not limited to this. The lamp housing 10 can also be a sheet metal part alone, or a plastic part alone, or other metal parts other than sheet metal parts alone.
[0052] The lamp housing 10 has a light outlet 10A. It is understood that the light emitted by the light source can be emitted through the light outlet 10A. The shape of the light outlet 10A can be circular, square, triangular or irregular, etc. For example, the shape of the light outlet 10A is circular, which has an axial direction, and this embodiment does not limit this. The lamp housing 10 is provided with an interface portion 11, which is located at the light outlet 10A.
[0053] The fastening assembly 20 is arranged at the front side of the interface portion 11 along the axial direction of the light outlet 10A, and includes a rotating member 21 and a pressing member 22. The rotating member 21 can be arranged in a ring shape, and the rotating member 21 can include at least one of a sheet metal member and a plastic member, which is not limited in this embodiment. The rotating member 21 is connected to the interface portion 11. It can be understood that the rotating member 21 can rotate under the application of external force, for example, when the user applies an external force along the circumference of the light outlet 10A, the rotating member 21 can rotate. The rotating member 21 abuts against the pressing member 22.
[0054] The clamping member 22 may be arranged in a ring shape to avoid the light emitted from the light outlet 10A. The clamping member 22 may include at least one of a sheet metal member and a plastic member, which is not limited in this embodiment. The clamping member 22 is arranged on the interface portion 11, and cooperates with the interface portion 11 to form an interface 30, which is used to cooperate with the bayonet of the optical accessory. It should be noted that the bayonet referred to here may be a more commonly used Bowers bayonet, or a bayonet of different specifications set by various manufacturers, which is not limited in this embodiment.
[0055] The rotating member 21 can rotate relative to the lamp housing 10 around the axial direction of the light outlet 10A. It can be understood that when an external force is applied to the rotating member 21 to rotate, the rotating member 21 can move relative to the interface portion 11 in the axial direction, and on the basis of the rotating member 21 abutting against the pressing member 22, the rotating member 21 moves itself to make the pressing member move backward or forward in the axial direction, that is, the pressing member 22 can reciprocate in the axial direction, for example, when the rotating member 21 rotates in the clockwise direction, the rotating member 21 drives the pressing member 22 to move from front to back in the axial direction, so that the space of the interface 30 is reduced to clamp the bayonet, and when the rotating member 21 rotates in the counterclockwise direction, the rotating member 21 drives the pressing member 22 to move from back to front in the axial direction, so that the space of the interface 30 is expanded to release the bayonet.
[0056] It should be noted that the lamp housing 10 may include a front housing 12 and a rear housing 13, and the front and rear directions referred to here can be corresponded with the front housing 12 and the rear housing 13 as a reference, that is, the direction from front to back is the direction in which the front housing 12 points to the rear housing 13 in the axial direction, and the direction from back to front is the direction in which the rear housing 13 points to the front housing 12 in the axial direction, and the front and rear directions here are parallel to the length direction of the lamp housing 10.
[0057] Based on the axial backward or forward movement of the clamping piece 22, the axial space of the interface 30 can be correspondingly reduced or expanded to correspond to clamping or releasing the bayonet. It can be understood that in the axial direction, when the clamping piece 22 is away from the interface portion 11, the axial space of the interface 30 is reduced, and when the clamping piece 22 is close to the interface portion 11, the axial space of the interface 30 is expanded.
[0058] The technical solution of the present application uses the rotating member 21 to drive the pressing member 22 to reciprocate along the axial direction, so as to achieve the clamping or fixing of the bayonet by the interface 30. In this way, after the bayonet enters the interface 30, the space of the interface 30 in the axial direction is reduced, so that the two axially opposite walls of the interface 30 press against the bayonet, thereby achieving the clamping of the bayonet. Compared with the loose connection between the interface 30 and the bayonet in the related art, the connection between the interface 30 and the bayonet in the present application can make the connection between the interface 30 and the bayonet more secure, thereby effectively reducing the probability of the optical accessory shaking when connected behind the movie light.
[0059] Furthermore, if the fastening assembly 20 is axially arranged on the rear side of the interface portion 11, then in this form, an escape hole needs to be reserved in the interface portion 11 so that the user can operate the rotating member 21 to rotate through the escape hole, or allow the handle member 60 to pass through the escape hole. Due to the existence of the escape hole, impurities such as dust and liquid may easily enter, and the impurities may easily enter the interior of the lamp housing 10 from the light outlet 10A, etc., and may easily affect the devices inside the photography light 100.
[0060] Therefore, in this embodiment, the fastening assembly 20 is arranged on the front side of the interface part 11, and there is no need to reserve an escape opening on the interface part 11, thereby effectively reducing the probability of impurities entering the interior of the lamp housing 10 and effectively extending the service life of the photography light 100.
[0061] See also Figure 1 In some embodiments, the photographic light 100 further includes a support frame (not shown in the figure), and the support frame can be roughly U-shaped or V-shaped, which is not limited in this embodiment.
[0062] The support frame is connected to opposite sides of the lamp housing 10 along the width direction thereof to support the lamp housing 10. The support frame can move relative to the lamp housing 10 along the front-rear direction of the lamp housing 10. It is understandable that in actual use, the photography light 100 will be used with different optical accessories, and the weights of different optical accessories will be different. Therefore, when the photography light 100 is connected with different optical accessories, the overall center of gravity position will change. Based on this, in this embodiment, the user can adjust the position of the support frame according to the actual center of gravity position of the photography light 100 after the photography light 100 is connected with a specific optical accessory, so that the support frame can stably support the photography light 100 connected with the optical accessory, thereby ensuring the stability of the photography light 100 during use.
[0063] Further, the support frame has a fixing portion (not shown in the figure), and at least two shifting portions (not shown in the figure) are arranged on the side wall of the lamp housing 10 along the width direction thereof, and the at least two shifting portions are arranged at intervals along the front-to-back direction of the lamp housing 10. The fixing portion can be selectively connected to one of the shifting portions, so that the support frame can be fixed at the set distance position after being moved relative to the lamp housing 10 by a set distance.
[0064] Thus, in this embodiment, the cooperation between the support frame and the lamp housing 10 is adjustable in gears, and corresponding gears can be set according to the weight of different optical accessories, so that users can use it conveniently and the operation is fast and convenient.
[0065] Please refer to Figure 1-Figure 4 In some embodiments, the photographic light 100 further includes a handle 60, which is fixedly connected to the rotating member 21. The handle 60 and the rotating member 21 may be separate components or integrated components. When they are separate components, the two may be connected in a detachable manner such as a threaded connection, which is not limited in this embodiment. The number of the handle 60 may be one or more. When there are more than one handle, the multiple handles 60 are arranged at intervals. The number of the handle 60 is not specifically limited in this embodiment.
[0066] On the basis of the fixed connection between the handle 60 and the rotating member 21, the rotating member 21 can be driven to rotate axially relative to the lamp housing 10 under the action of external force. It is understandable that when the user needs to rotate the rotating member 21, the user can hold the handle 60 and apply force to the handle 60 to rotate the rotating member 21, which is convenient for the user to operate and improves the user experience.
[0067] In some structural forms, along the axial direction of the light outlet 10A, the projection of the handle 60 is located inside the lamp housing 10. In this way, when the photography light 100 is placed on a work surface, such as a desktop, the handle 60 will not protrude from the lamp housing 10 in the axial direction, so that the lamp housing 10 can be placed stably for subsequent stable lighting and fill-in work.
[0068] Please refer to Figure 2-Figure 4 In some structural forms, the handle member 60 includes a handle portion 61 and a connecting portion 62 connected to each other, the handle portion 61 is used for a user to push or hold, and the connecting portion 62 is fixedly connected to the rotating member 21.
[0069] The connecting portion 62 includes a connecting section 621 and an abutting section 622, and the connecting section 621 and the abutting section 622 are connected and are arranged at an angle. The connecting section 621 is fixedly connected to the front side of the rotating member 21 along the axial direction, such as by threaded connection, and the abutting section 622 abuts against the outer side of the rotating member 21. In this way, the contact area between the connecting portion 62 and the rotating member 21 can be increased by utilizing the cooperation between the connecting section 621 and the abutting section 622 and the rotating member 21, so as to increase the friction between the connecting portion 62 and the rotating member 21, thereby helping to reduce the shaking or instability that may occur when the handle 60 drives the rotating member 21 to rotate, and can improve the rotation synchronization.
[0070] The handle portion 61 is provided with anti-skid ribs, which include a plurality of anti-skid ribs arranged at intervals. Thus, the anti-skid ribs can be provided to effectively increase the friction between the user's hand and the handle portion 61, thereby improving the anti-skid performance and thus effectively improving the user's experience.
[0071] Please refer to Figure 1-Figure 4 In some embodiments, the handle member 60 includes at least two, and the at least two handle members 60 are symmetrically arranged along the axial direction. In this way, the at least two handle members can be convenient for the user to hold with both hands and both hands can apply force together, which is more convenient to operate, especially in the use scenario of a high-power photography light 100. Usually, the structure of the rotating member 21 is relatively heavier, so it is more convenient when both hands can apply force, and it can also avoid concentrated force on a single handle member 60 to cause damage to the handle member 60, effectively extending the service life of the handle member 60.
[0072] See also Figure 3 In some embodiments, an abutting protrusion 214 is disposed on the outer side of the rotating member 21 , and two limit blocks 70 are also disposed on the lamp housing 10 . The two limit blocks 70 are disposed at opposite sides of the abutting protrusion 214 along the axial direction of the lamp housing 10 .
[0073] Among them, the two limit stops 70 are both located within the rotation trajectory of the handle member 60 and are used to resist the abutment protrusion 214. In this way, the movement distance of the abutment protrusion 214 can be limited by the cooperation of the two limit stops 70 to limit the axial movement range of the rotating member 21, thereby avoiding the separation of the rotating member 21 and the interface portion 11, and further preventing the rotating member 21 from being lost.
[0074] For example, when the rotating member 21 and the interface portion 11 are threadedly connected, if the moving distance of the abutting protrusion 214 is not limited, the rotating member 21 may be separated from the interface portion 11. Therefore, through the cooperation of the two limit blocks 70, the moving distance of the abutting protrusion 214 can be limited, thereby limiting the displacement of the rotating member 21 in the axial direction to prevent the rotating member 21 from being separated from the interface portion 11.
[0075] Please refer to Figure 2-Figure 4 In some embodiments, the pressing member 22 is provided with a first contact structure 80. It is understood that the first contact structure 80 is electrically connected to a control panel (not shown in the figure) of the photographic light 100. The optical accessory is provided with a second contact structure (not shown in the figure).
[0076] In which, when the interface 30 is in a state of being matched with the bayonet, the first contact structure 80 is used to contact and conduct with the second contact structure to achieve functions such as power supply and communication.
[0077] Taking the optical accessory as an example of a focusing tube, when the focusing tube has the function of automatic focusing, a power source is required to power it in order to realize the automatic focusing function. Therefore, when the first contact structure 80 is in contact with the second contact structure and is turned on, the photographic light 100 can power the focusing tube so that the focusing tube has electrical energy and can realize automatic focusing.
[0078] Please refer to Figure 5-Figure 8 In some embodiments, a lap step 22A is formed on the surface of the pressing member 22 facing away from the lamp housing 10 along the axial direction. The lap step 22A may be arranged to extend along the circumference of the pressing member 22 .
[0079] The rotating member 21 includes a main body 211 and a lap portion 212. The main body 211 is the main part of the rotating member 21, and the main body 211 can be arranged in an annular shape. The lap portion 212 can be arranged to extend along the circumference of the main body 211, and the lap portion 212 is connected to the main body 211 and extends toward the pressing member 22.
[0080] The overlapping portion 212 overlaps the overlapping step 22A. It is understandable that the overlapping step 22A has an abutting surface and a limiting surface arranged at an angle, and the angle can be 90 degrees, so that the two are arranged vertically. Of course, the angle can also be 70 degrees, 80 degrees or 90 degrees, etc., and this embodiment does not limit this.
[0081] In this way, on the one hand, the overlapping portion 212 can abut against the abutting surface of the overlapping step 22A to achieve the abutment between the rotating member 21 and the clamping member 22; on the other hand, the limiting surface of the overlapping step 22A can limit the overlapping portion 212 to prevent the rotating member 21 from deviating.
[0082] Please refer to Figure 7-Figure 8 In some embodiments, the interface portion 11 includes an interface body 111 and a connection body 112 .
[0083] The interface body 111 is located at the light outlet 10A and cooperates with the pressing member 22 to form the outlet 30. The connecting body is connected to the interface body 111 and axially protrudes on the front side of the lamp housing 10. The connecting body 112 is sandwiched between the main body 211 of the rotating member 21 and the pressing member 22.
[0084] In this way, the connecting body 112 is clamped by the rotating member 21 and the pressing member 22, and the rotating member 21 and the pressing member 22 can be used to protect the connecting body 112, and at the same time, the connecting body 112 can be at least partially covered by the rotating member 21 and the pressing member 22, so as to achieve an aesthetic effect. In addition, since the connecting body 112 is axially convexly arranged on the front side of the lamp housing 10, compared with the form in which the connecting body 112 is axially concavely arranged on the lamp housing 10, it can avoid occupying the internal space of the lamp housing 10, so that the utilization rate of the internal space of the lamp housing 10 is greater, so that the internal space of the lamp housing 10 can be arranged with larger components, such as radiators, etc., so that the accommodation effect of the lamp housing 10 is effectively improved.
[0085] See also Figure 8 Furthermore, the overlapping portion 212, the main body 211 and the clamping piece 22 cooperate to form a clamping space 10B. The connecting body 112 is disposed in the clamping space 10B and is clamped by two opposite side walls of the clamping space 10B. It can be understood that one side wall of the clamping space 10B is formed by the main body 211, and the other side wall is formed by the clamping piece 22.
[0086] In this way, by providing the clamping space 10B, not only can the overlapping portion 212 and the clamping piece 22 be used to protect and shield the connecting body 112, but also the overlapping portion 212 can protect and shield the connecting body 112 in the axial direction and from front to back, so as to achieve better protection and aesthetic effects.
[0087] Please refer to Figure 5 , Figure 6 as well as Figure 8 In some embodiments, the main body 211 of the rotating member 21 is provided with an internal thread structure 213 , and the connecting body 112 of the interface portion 11 is provided with an external thread structure 1121 .
[0088] The internal thread structure 213 is threadably matched with the external thread structure 1121 , so that the rotating member 21 is threadably connected to the interface portion 11 , thereby enabling the rotating member 21 to rotate relative to the lamp housing 10 around the axial direction.
[0089] In this way, the threaded connection can improve the reliability of the connection between the rotating member 21 and the connecting body 112, preventing the two from being separated during the rotation process, and can also provide the user with a smooth and stable hand feeling when applying force to the rotating member 21, thereby improving the user's experience. In addition, the threaded connection also facilitates the user to disassemble and assemble the rotating member 21 and the interface part 11, and the operation is very convenient.
[0090] In addition, the connection body 112 is clamped between the main body 211 and the clamping piece 22, which can also provide a good protective effect on the external thread structure 1121 provided on the connection body 112, thereby preventing the external structure from causing damage to the external thread structure 1121, and effectively reducing the probability of failure of the external thread structure 1121. The internal thread structure 213 is formed on the inner wall of the main body 211, and is therefore not easily damaged by the external structure. This is beneficial to extending the service life of the fastening assembly 20.
[0091] Please refer to Figure 5-Figure 6 In some embodiments, the connection body 112 is detachably connected to the interface body 111, and the detachable connection method includes but is not limited to threaded connection, snap connection, etc. In this way, even if the external thread structure 1121 provided on the connection body 112 fails, the connection body 112 can be removed from the interface body 111 and replaced with a new connection body 112, so that the fastening assembly 20 can continue to be used.
[0092] In actual operation, if the internal thread structure 213 fails, the main body 211 can be disconnected from the connecting body 112, and the main body 211 can be replaced to continue using the fastening assembly 20; and if the external thread structure 1121 fails, the main body 211 can be disconnected from the connecting body 112 first to disassemble the main body 211, and then the pressing member 22 can be disconnected from the front shell 12 of the lamp housing 10 to disassemble the pressing member 22, and finally the connecting body 112 can be disconnected from the interface body 111, and the connecting body 112 can be replaced to continue using the fastening assembly 20. This arrangement is conducive to extending the service life of the fastening assembly 20 and preventing at least one of the internal thread structure 213 and the external thread structure 1121 from failing, so that the fastening assembly 20 cannot be used any more.
[0093] In the form of realizing the rotation of the rotating member 21 relative to the lamp housing 10, in addition to the threaded connection form of the above-mentioned embodiment, optionally, the connecting body 112 of the interface part 11 is provided with a plug-in protrusion (not shown in the figure), and the main body 211 of the rotating member 21 is provided with a plug-in groove (not shown in the figure).
[0094] The plug-in groove extends along the circumference of the lamp housing 10 and has a first end and a second end. It can be understood that the first end and the second end are located at two ends of the plug-in groove along its extension direction. The first end is located in front of the second end in the axial direction.
[0095] The plug-in protrusion is plugged into the plug-in groove and can reciprocate between the first end and the second end, so that the rotating member 21 can rotate relative to the lamp housing 10 around the axial direction. Specifically, when the plug-in protrusion moves from the first end to the second end, the rotating member 21 drives the pressing member 22 to move from front to back in the axial direction, and the space of the interface 30 is reduced; and when the plug-in protrusion moves from the second end to the first end, the driving member drives the pressing member 22 to move from back to front in the axial direction, and the space of the interface 30 is expanded.
[0096] It is understandable that the end surface of the first end and the end surface of the second end can limit the insertion protrusion, so that the rotation trajectory range of the rotating member 21 can be limited by the first end and the second end, thereby limiting the axial displacement of the rotating member 21.
[0097] It should be noted that the connection body 112 is sandwiched between the main body 211 and the pressing member 22, which can also provide a good protection effect on the plug-in protrusion and the plug-in groove, which will not be elaborated in detail here.
[0098] In this embodiment, the plug-in protrusion cooperates with the plug-in groove to realize the rotation of the rotating member 21 relative to the lamp housing 10, and the structure is relatively simple, which is also convenient for manufacturing and production in the workshop. Of course, in other embodiments, the interface part 11 may be provided with a plug-in groove, and the rotating member 21 may be provided with a plug-in protrusion, which can also achieve the same effect, and this embodiment does not limit this.
[0099] Please refer to Figure 7-Figure 8 In some embodiments, the surface of the overlap portion 212 facing away from the lamp housing 10 along the axial direction is coplanar with the surface of the pressing member 22 facing away from the lamp housing 10 along the axial direction. In this way, the fastening assembly 20 can be made more compact as a whole, and when the two surfaces are flush, the whole will be more regular and beautiful.
[0100] Please refer to Figure 5-Figure 6 In some embodiments, the photographic light 100 further includes a first compression spring 40, which is disposed between the pressing member 22 and the interface portion 11. The number of the first compression spring 40 may be one or more. When there are more than one first compression spring 40, the plurality of first compression springs 40 are arranged at intervals along the circumference of the interface portion 11. The embodiment does not limit the number of the first compression springs 40.
[0101] One end of the first compression spring 40 abuts against the side of the pressing member 22 facing the interface portion 11, and the other end abuts against the side of the interface portion 11 facing the pressing member 22. Specifically, when the rotating member 21 abuts against the pressing member 22 and drives the pressing member 22 to move axially backward, the first compression spring 40 will be squeezed by the interface portion 11 and the pressing member 22 and compressed, and when the pressing member 22 needs to move axially forward later, the rotating member 21 will move axially forward, at which time the first compression spring 40 will rebound and give the pressing member 22 an axially forward rebound force, so that the pressing member 22 can move axially forward.
[0102] In this way, the first compression spring 40 can be used to realize that the rotating member 21 drives the pressing member 22 to move axially forward, which is convenient to operate and provides a better user experience. At the same time, the first compression spring 40 has the advantages of high stability and high reliability, so that the pressing member 22 can move axially forward during long-term use, thereby extending the service life of the fastening assembly 20.
[0103] Of course, in other embodiments, the first compression spring 40 may also be replaced by an elastic structure such as a spring sheet, and any structure may be selected as long as it can have a rebound effect on the pressing member 22 , and this embodiment does not impose any limitation on this.
[0104] Furthermore, a receiving groove is formed on one side of the pressing member 22 facing the interface portion 11, and one end of the first compression spring 40 abuts against the groove wall surface of the receiving groove facing the interface portion 11. In this way, the pressing member 22 can be used to form a receiving groove for accommodating the first compression spring 40, so that the distance between the pressing member 22 and the interface portion 11 along the axial direction can be shortened, effectively reducing the overall axial size of the video light 100, making the overall size of the video light 100 more compact.
[0105] See also Figure 2 In some embodiments, the interface 30 includes an inlet section 31A and a fastening section 31B, and the inlet section 31A is connected to the fastening section 31B and has an opening. It is understandable that when the bayonet is installed with the interface 30, the optical accessory will move axially backward, so that the bayonet enters the inlet section 31A through the opening, and then the optical accessory will rotate around the axial direction to enter the fastening section 31B from the inlet section 31A, so that the space of the interface 30 is reduced by moving the pressing member 22 axially backward, so as to clamp the bayonet; on the contrary, when the bayonet is separated from the interface 30, the space of the interface 30 is expanded by moving the pressing member 22 axially forward, so as to release the bayonet, and the optical accessory will rotate in the opposite direction around the axial direction to retreat from the fastening section 31B to the inlet section 31A, and then the optical accessory will move axially forward, so that the bayonet exits through the opening, so as to separate the bayonet from the interface 30.
[0106] The fastening assembly 20 also includes a locking piece 23, which is connected to the interface portion 11 and telescopically disposed in the inlet section 31A. Specifically, the inlet section 31A may be provided with a first opening, and the locking piece 23 is disposed in the first opening to achieve a telescopic function.
[0107] In which, when the bayonet enters the entrance section 31A, the locking piece 23 can extend out of the entrance section 31A, and after the bayonet enters the fastening section 31B, the locking piece 23 can at least partially retract into the entrance section 31A, and is used to limit and resist the bayonet along the circumference of the interface portion 11 to prevent the bayonet from detaching from the fastening section 31B.
[0108] With this arrangement, the fastening assembly 20 not only has the active fastening and locking function of clamping the bayonet with the interface 30, but also has the function of limiting the bayonet with the locking piece 23. With this arrangement, on the one hand, it can play a secondary locking function for the bayonet, more effectively reducing the risk of the bayonet and the interface 30 being separated during the use of the video light 100, and on the other hand, even if the active fastening and locking functions of the fastening assembly 20 fail, for example, at least one of the external thread structure 1121 and the internal thread structure 213 is damaged, resulting in the failure of the active fastening and locking functions, the locking piece 23 still has the function of limiting the bayonet, so that the user can continue to match the optical accessory with the video light 100, and the bayonet can still remain in the installed state with the interface 30, without hindering the user's normal use of the optical accessory, greatly improving the user's experience.
[0109] Please refer to Figure 5-Figure 6 , further comprising a connecting member 50, wherein the connecting member 50 has an internal thread. A threaded column 221 is provided on one side of the pressing member 22 facing the interface portion 11, and the threaded column 221 has an external thread.
[0110] The threaded column 221 is passed through the interface portion 11, wherein the interface portion 11 may be provided with a second opening, the threaded column 221 is passed through the second opening, and the threaded column 221 is threadedly connected to the connector 50. It is understood that the connector 50 is connected to one end of the threaded column 221 passing through the interface portion 11. The threaded column 221 can move relative to the interface portion 11 in the axial direction, and the connector 50 can prevent the threaded column 221 from being separated from the interface portion 11. It is understood that the outer diameter of the connector 50 can be larger than the caliber of the second opening, so that the connector 50 will abut against the interface portion 11 to prevent the threaded column 221 from being separated from the interface portion 11.
[0111] In this way, the threaded column 221 can be used to cooperate with the connecting piece 50, and the connecting piece 50 will abut against the interface part 11, so that there is a connection relationship between the clamping piece 22 and the interface part 11, and the connection is relatively firm. Therefore, when the active tightening and locking functions fail, for example, at least one of the external thread structure 1121 and the internal thread structure 213 is damaged, resulting in the failure of the locking function, it can still ensure that the bayonet and the interface 30 remain in an installed state, so that the user can continue to use the optical accessory and the photography light 100.
[0112] Optionally, the number of the threaded column 221, the connecting member 50 and the second opening is multiple, and the multiple threaded columns 221 are arranged at intervals along the circumference of the clamping member 22, and one threaded column 221, one connecting member 50 and one opening are matched to each other. In this way, the connection reliability between the clamping member 22 and the interface portion 11 can be improved in the circumferential direction.
[0113] In some embodiments, one of the interface portion 11 and the pressing member 22 is provided with a positioning protrusion, and the other is provided with a positioning groove, wherein the positioning protrusion is used to be inserted into the positioning groove to be positioned and matched with the positioning groove. In the actual assembly process, the positioning protrusion and the positioning groove can be used to achieve the pre-positioning of the interface portion 11 and the pressing member 22, and the assembly is accurate and convenient, thereby improving the assembly accuracy and efficiency of the workshop.
[0114] Please refer to Figure 4-Figure 6 In some embodiments, the locking member 23 includes a base 231, a locking portion 232, and an unlocking portion 233. The base 231 is axially arranged at the rear side of the interface portion 11 and connected to the interface portion 11. The base 231 can move relative to the interface portion 11 along the telescopic direction of the locking member 23. The locking member 23 is fixedly connected to the base 231 and telescopically penetrates the inlet section 31A. The unlocking portion 233 is fixedly connected to the base 231 and is spaced apart from the locking portion 232. The unlocking portion 233 is arranged on the outer side of the rotating member 21, and is used to drive the base 231 to move axially backward so that the locking portion 232 extends out of the inlet section 31A.
[0115] It can be understood that, when the bayonet enters the entrance section 31A, the bayonet can drive the base 231 to move axially backward by abutting the locking portion 232, so that the locking portion 232 extends out of the entrance section 31A, and then the bayonet can enter the fastening section 31B from the entrance section 31A, and after the bayonet enters the fastening section 31B, the base 231 will drive the locking portion 232 to move axially forward, so that the locking portion 232 can at least partially retract into the entrance section 31A; When the fixing section 31B is retracted to the entrance section 31A, the unlocking portion 233 can be operated at this time so that the unlocking portion 233 drives the base 231 to move axially backward, so that the locking portion 232 extends out of the entrance section 31A, and then the bayonet can be retracted from the fastening section 31B to the entrance section 31A, and then withdrawn through the opening to achieve separation. For example, the unlocking portion 233 can be a button structure, and by pressing the unlocking portion 233 to move axially backward, the unlocking portion 233 can be extended out of the entrance section 31A.
[0116] The outer wall of the rotating part is provided with a stopper 215, which is used to resist the unlocking part 233 when the interface 30 clamps the bayonet, so as to prevent the unlocking part 233 from driving the base 231 to move backward along the axial direction. In this way, in the actual operation, it is possible to prevent the bayonet from being disengaged from the interface 30 due to the accidental contact of the locking part 232, so that the operation is safe and the optical accessories are prevented from falling.
[0117] When unlocking is required, the rotating part 21 needs to be rotated, so that the clamping part 22 releases the bayonet, and at this time, the unlocking portion 233 will not contact the unlocking portion 233 when moving axially backward. For example, when the axial limiting portion 215 is staggered from the unlocking portion 233, the user can operate the unlocking portion 233 to make the locking portion 232 extend out of the entrance section 31A, so that the bayonet can be withdrawn from the fastening section 31B to the entrance section 31A, and then exit through the opening.
[0118] In some embodiments, the limiting portion 215 can be a limiting rib and is extended along the axial direction of the rotating member 21. The width of the limiting portion 215 along the axial direction gradually increases along the extension direction of the limiting portion 215. Therefore, the limiting portion 215 has a head end and a tail end along its extension direction, and the width of the head end along the axial direction is greater than the width of the tail end, and when the interface 30 clamps the bayonet, the head end is opposite to the unlocking portion 233 along the axial direction, so that the head end can resist the limiting portion 215 to prevent the unlocking portion 233 from driving the base 231 to move backward along the axial direction.
[0119] Please refer to Figure 5-Figure 6In some embodiments, the locking member 23 further includes a second compression spring 234, one end of the second compression spring 234 abuts against a side of the base 231 away from the unlocking portion 233, and the other end can abut against other components located in the lamp housing 10. In this way, the second compression spring 234 can provide a rebound force for the base 231, so that after the user releases the unlocking portion 233, the base 231 drives the locking portion 232 and the unlocking portion 233 to automatically reset.
[0120] It can be understood that when the user presses the unlocking part 233, the pressing force at this time will be greater than the rebound force of the second compression spring 234, so as to overcome the second compression spring 234 to realize the pressing operation. After the user releases the unlocking part 233, the rebound force of the second compression spring 234 will drive the base 231 to reset, thereby realizing the reset of the locking part 232 and the unlocking part 233.
