[0055] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0056] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0057] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply 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 on this application.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0059] See also Figure 1 The clamping mechanism 100 provided in an embodiment of the present application will now be described. The clamping mechanism 100 is used to clamp an object. In this embodiment, the object to be clamped is specifically a lamp stick 2000, and the clamping mechanism 100 is used to clamp and secure the lamp stick 2000. Of course, in other embodiments of the present application, the clamping mechanism 100 can also be used to clamp other structures, such as a lamp tube or a column, and this is not intended to be the sole limitation.

[0060] See also Figure 5 and Figure 6 The clamping mechanism 100 includes a mounting base 110, a driving structure 120, two clamping members 130, and two elastic members. The driving structure 120 is mounted on the mounting base 110; the two clamping members 130 are arranged opposite each other and spaced apart, and are swingably mounted on the mounting base 110; the two clamping members 130 are respectively connected to the output ends of the driving structure 120, and can swing toward each other under the drive of the driving structure 120 to clamp the object to be clamped; and the two elastic members are elastically connected to the two clamping members 130, so that the two clamping members 130 have a pre-tightening clamping force when not driven by the driving structure 120.

[0061] The two clamping members 130 are both swingably mounted on the mounting base 110. The clamping members 130 have a swing fulcrum, and the clamping members 130 are swingably mounted on the mounting base 110 about the swing fulcrum. The driving structure 120 drives the two clamping members 130 to swing, which means that the driving structure 120 pushes the clamping members 130 to a position outside the swing fulcrum, thereby causing the two clamping members 130 to swing toward each other to clamp the object to be clamped.

[0062] In addition, the elastic member is elastically connected to a position other than the swing fulcrum on the clamping member 130; the elastic member enables the two clamping members 130 to have a pre-tightened clamping force, which means that when the driving structure 120 has no driving force on the clamping member 130, the clamping member 130 will swing in the opposite direction following the driving end of the driving structure 120, specifically, the two clamping members 130 rotate in opposite directions, and at this time the elastic member can apply an elastic supporting force or an elastic pulling force to the clamping member 130 to ensure that the clamping member 130 has a certain preset clamping force.

[0063] The clamping mechanism 100 in this embodiment, through the arrangement of the driving structure 120 and the two clamping members 130, the driving structure 120 can drive the two clamping members 130 to swing toward each other to clamp the object to be clamped, so that when the lamp stick 2000 is clamped by the clamping mechanism 100, the lamp stick 2000 can be clamped firmly, and at the same time, when the lamp stick 2000 is adjusted to a large angle, there is no risk of the lamp stick 2000 falling off. In addition, through the provision of the elastic member, when the driving force of the driving structure 120 on the clamping member 130 disappears, the elastic member can apply an elastic supporting force or an elastic pulling force to the clamping member 130 to prevent the clamping member 130 from loosening and becoming difficult to be driven again by the driving structure 120. At the same time, the two clamping members 130 also tend to swing toward each other, that is, they have a pre-tightening clamping force on the lamp stick 2000, so that when the lamp stick 2000 is installed in the clamping mechanism 100, the clamping mechanism 100 has preliminary positioning and preset supporting force on the lamp stick 2000, thereby ensuring the clamping stability of the clamping mechanism on the lamp stick 2000.

[0064] Optionally, the elastic member may be a spring, a compression spring or a torsion spring.

[0065] In one embodiment, see Figures 5 to 7 The elastic member is a spring clip 141 having a connecting end 1411 and an abutting end 1412 disposed opposite each other. The connecting end 1411 is fixed to the mounting base 110. The abutting ends 1412 of the two spring clips 141 respectively abut against opposite sides of the two clamping members 130, causing the two clamping members 130 to swing toward each other. When the driving force of the drive structure 120 on the clamping members 130 disappears, the spring clip 141 can abut the clamping members 130 at a certain angle, so that the two clamping members 130 have a certain pre-tightening clamping force.

[0066] In one embodiment, see 5 and Figure 7 The clamping mechanism 100 includes a pre-pressed part 140. The pre-pressed part 140 includes a mounting plate 142 and two spring clips 141; the mounting plate 142 is fixed to the mounting seat 110, specifically, the mounting plate 142 is attached to the mounting seat 110 and is locked by screws. The two spring clips 141 are respectively connected to the opposite ends of the mounting plate 142, and the two spring clips 141 are respectively in contact with the opposite sides of the two clamping members 130 so that the two clamping members 130 have a tendency to swing toward each other, that is, they have a pre-tightening clamping force. In this embodiment, the two spring clips 141 are connected together and installed on the mounting seat 110 by the mounting plate 142, which not only makes the two spring clips 141 easy to manufacture, but also makes the two spring clips 141 easy to install. In addition, the structural strength of the two spring clips 141 can also be improved.

[0067] In this application, please see Figure 7 Since the two clamping members 130 are respectively arranged between the two elastic sheets 141, an avoidance groove 143 is further opened in the center of the mounting plate 142, and the two elastic sheets 141 are respectively connected to the opposite side walls of the avoidance groove 143 along the first direction X.

[0068] In another embodiment of the present application, see Figure 2 The above two elastic members can also be connected into an integrated elastic sheet 150, which is connected between the two clamping members 130, thereby giving the two clamping members 130 a preset pulling force to move closer to each other, ensuring that the two clamping members 130 have a preset clamping force.

[0069] Specifically, connecting portions 151 are formed at the opposite ends of the elastic sheet 150, and a receiving groove (not marked in the figure) is formed on the clamping member 130; the connecting portion 151 is arc-shaped, and the connecting portion 151 can be axially inserted into the receiving groove, and the connecting portion 151 can be elastically deformed to abut against the inner wall of the receiving groove, thereby connecting the opposite ends of the spring sheet 141 with the two clamping members 130 respectively.

[0070] In addition, the elastic piece 141 extends in an arc-shaped wave shape between the two connecting portions 151 . The arc-shaped wave shape enables the elastic piece 141 to have a telescopic elastic force.

[0071] In another embodiment of the present application, the two elastic members may also be springs connected as one body, and the springs are connected between the two clamping members 130, thereby giving the two clamping members 130 a preset pulling force to move closer to each other, ensuring that the two clamping members 130 have a preset clamping force.

[0072] In one embodiment, see Figure 2 、 Figure 5 、 Figure 6 and Figure 8A clamping portion 131 is formed on the clamping member 130, and the two clamping portions 131 on the two clamping members 130 are arranged to be inclined toward each other; the two clamping portions 131 are used to be inserted into two relative positions of the clamped piece to clamp the clamped piece.

[0073] The two clamping portions 131 are tilted toward each other, which means that the two clamping portions 131 are tilted toward each other. Figure 5 Taking the two clamping parts 131 distributed left and right as an example, the left clamping part 131 extends obliquely to the right, specifically, it can be extended obliquely to the right and in a direction away from the mounting seat 110 or it can be extended obliquely to the right and in a direction toward the mounting seat 110; the right clamping part 131 extends obliquely to the left, specifically, it can be extended obliquely to the left and in a direction away from the mounting seat 110 or it can be extended obliquely to the left and in a direction toward the mounting seat 110. Specifically, of the two clamping parts 131 in this application, the left clamping part 131 extends obliquely to the right and in a direction away from the mounting seat 110, and the right clamping part 131 extends obliquely to the left and in a direction toward the mounting seat 110. This arrangement enables the two clamping parts 131 to clamp and support the workpiece facing each other, thereby ensuring the clamping reliability and stability of the clamping mechanism 100 on the workpiece.

[0074] For details, please refer to Figure 5 and Figure 6 The two clamping members 130 are spaced apart along a first direction X, forming a clamping space. The clamping portion 131 is a bar formed on the opposing clamping surfaces of the two clamping members 130, extending along a second direction Y. The first direction X and the second direction Y are perpendicular to each other. A slot 2110 is formed on the outer wall of the clamped component. During installation, the component can pass through the clamping space in the second direction Y, and the bar can be inserted into the slot 2110 of the component along the second direction Y. The driving mechanism 120 then drives the two clamping members 130 to swing toward each other, causing the two bar to clamp the inner walls of the slot 2110, thereby clamping the component.

[0075] In the present application, the bottom shell 2100 of the lamp stick 2000 is made of a profile, the surface of which is distributed with multiple slots 2110 extending along the axial direction (i.e., the second direction Y) of the lamp stick 2000. In other words, when the clamping mechanism 100 of the present application is used to clamp the lamp stick 2000, no structural modifications to the lamp stick 2000 are required to achieve the clamping member 130's clamping of the lamp stick 2000. Furthermore, because the bottom shell 2100 of the lamp stick 2000 is not illuminated, the clamping mechanism 100 does not block light from the lamp stick 2000 when clamping the lamp stick 2000.

[0076] See also Figure 2 The width of the insert gradually decreases from the clamping surface to the end, thereby facilitating the insertion of the insert into the slot 2110 of the light stick 2000 .

[0077] In one embodiment, see Figure 5 and Figure 6 The mounting base 110 is formed with a rotating shaft 111, and the clamping member 130 is formed with a rotating groove 132. The rotating groove 132 is rotatably sleeved on the rotating shaft 111, so that the clamping member 130 is swingably mounted on the mounting base 110 around the rotating shaft 111. In particular, by forming the rotating shaft 111 on the mounting base 110, the process of additionally providing the rotating shaft 111 and mounting the rotating shaft 111 on the mounting base 110 can be reduced.

[0078] See also Figure 5 and Figure 6 The rotating shaft 111 extends along the second direction Y, and the rotating groove 132 penetrates the clamping member 130 along the second direction Y. During installation, the clamping member 130 is simply sleeved on the rotating shaft 111 along the second direction Y so as to align the rotating groove 132. This is convenient to operate.

[0079] At the same time, since the rotating shaft 111 is directly formed on the mounting seat 110 , the rotating shaft 111 is not a complete cylindrical shape, and the rotating groove 132 is not a complete cylindrical groove either.

[0080] Also, see Figure 5 The pre-pressed member 140 also includes two baffles 144, which are respectively arranged on opposite sides of the mounting plate 142 along the second direction Y. The two baffles 144 are respectively attached to opposite ends of the rotating shaft 111 along the second direction Y to serve as an axial limit for the rotating shaft 111.

[0081] In one embodiment, see Figure 5 and Figure 6The driving structure 120 includes a driving member 121, a pushing member 122, and a reset member 123. The driving member 121 is mounted on the mounting base 110 and is used to output reciprocating linear motion; the pushing member 122 is connected to the output end of the driving member 121 and abuts against the two clamping members 130 respectively; and the reset member 123 is connected to the pushing member 122 and is used to drive the pushing member 122 to reset. When it is necessary to clamp the lamp stick 2000, the driving member 121 first pushes the pushing member 122 to move in a positive linear motion, driving the pushing member 122 to push the two clamping members 130 at the same time, so that the two clamping members 130 rotate toward each other around the rotating shaft 111, and then drive the two inserting strips to be inserted into the two corresponding slots 2110 of the lamp stick 2000, thereby clamping the lamp stick 2000. At this time, the reset member 123 is compressed and accumulates elastic force; when it is necessary to release the lamp stick 2000, the driving member 121 outputs a reverse linear motion, and the pushing member 122 is reset in a straight line under the drive of the reset member 123. The pushing member 122 loses the pushing force on the clamping member 130, and the clamping member 130 swings in the opposite direction following the pushing member 122. At this time, since the two elastic members accumulate elastic force and abut on the two clamping members 130, the clamping member 130 remains stationary after rotating in the opposite direction by a preset angle. It can be understood that in other embodiments of the present application, the above-mentioned driving structure 120 can also fixedly connect the pushing member 122 with the output end of the driving member 121, so that the pushing member 122 can follow the output end of the driving member 121 to perform reciprocating linear motion, and the setting of the reset member 123 can be cancelled.

[0082] In one embodiment, see Figure 6 The pushing member 122 includes two pushing plates 1221 and a connecting plate 1222. The two pushing plates 1221 are relatively spaced apart and respectively abut against the two clamping members 130. The connecting plate 1222 is connected between the two pushing plates 1221 and is respectively connected to the driving member 121 and the reset member 123.

[0083] Specifically, the connecting plate 1222 is vertically connected to the two pushing plates 1221 respectively, and the connecting plate 1222 and the two pushing plates 1221 are an integral connection structure. The connecting plate 1222 abuts against the output end of the driving member 121, and the reset member 123 abuts between the connecting plate 1222 and the mounting seat 110. The end of the pushing plate 1221 away from the connecting plate 1222 abuts against the clamping member 130. Figure 6 When the driving member 121 drives the connecting plate 1222 to rise, the two pushing plates 1221 rise accordingly and push the opposite outer sides of the two clamping members 130 respectively, thereby driving the two clamping members 130 to swing toward each other to clamp the object to be clamped.

[0084] The pushing member 122 in this embodiment is provided with two pushing plates 1221, so that the same pushing member 122 can simultaneously push the two clamping members 130 to swing, and the two clamping members 130 swing synchronously, thereby simplifying the drive control of the two clamping members 130 and improving the consistency of the clamping of the two clamping members 130 on the clamped member, thereby improving the clamping reliability of the clamping mechanism 100 on the clamped member.

[0085] Also, see Figure 6 and Figure 8 The clamping member 130 is formed with a guide groove 133 for guiding the push plate 1221 to be inserted into the guide groove 133 so as to abut against the clamping member 130. Specifically, the guide groove 133 is V-shaped, with the opening of the guide groove 133 facing the push plate 1221. This configuration not only guides the push plate 1221 to abut against the clamping member 130 when the push plate 1221 moves upward, but also prevents the push plate 1221 from being completely separated from the clamping member 130 when the push plate 1221 returns downward, making it difficult to drive the clamping member 130 again.

[0086] In one embodiment, see Figure 5 and Figure 6 The driving member 121 includes a screw rod 1211, a nut 1212, and a handle 1213. The screw rod 1211 is vertically fixed to the mounting base 110; the nut 1212 is threadedly sleeved on the screw rod 1211; the pusher 122 is sleeved on the screw rod 1211 and abuts against the nut 1212; the handle 1213 is fixedly sleeved on the nut 1212 and is used to drive the nut 1212 to move back and forth on the screw rod 1211. When it is necessary to clamp the workpiece, the handle 1213 can be manually rotated, and the handle 1213 drives the nut 1212 to rotate on the screw rod 1211. Since the screw rod 1211 is fixed in position, the nut 1212 can also move upward on the screw rod 1211, and the nut 1212 pushes the pushing member 122 upward, thereby driving the clamping member 130 to clamp the workpiece. When it is necessary to loosen the workpiece, the handle 1213 is rotated in the opposite direction, driving the nut 1212 to rotate in the opposite direction on the screw rod 1211, so that the nut 1212 moves downward along the screw rod 1211, and the pushing member 122 is reset downward under the push of the reset member 123. In this embodiment, the provision of the handle 1213 makes it possible to manually adjust the clamping force of the clamping member 130 according to the installation situation, and the operation is convenient. It can be understood that in other embodiments of the present application, the driving member 121 can also select an automatic driving structure, such as a linear motor or a linear cylinder, etc. By abutting the pushing member 122 with the output end of the linear motor or the linear cylinder, the pushing member 122 can be pushed to move linearly by the linear motor or the linear cylinder.

[0087] Optionally, the reset member 123 may be a compression spring, a spring 141 or a torsion spring.

[0088] See also Figure 2 When the reset member 123 is a compression spring, the compression spring is sleeved on the screw rod 1211 and abuts between the mounting seat 110 and the pushing member 122 .

[0089] See also Figure 5 and Figure 9 When the reset member 123 is a spring, please refer to Figure 4 The reset member 123 includes a connecting piece 1231 and two elastic pieces 1232. The two elastic pieces 1232 are respectively connected to opposite ends of the connecting piece 1231. The two elastic pieces 1232 extend outward and away from the connecting piece 1231. The connecting piece 1231 is sleeved on the screw 1211 and abuts against the connecting plate 1222 of the pushing member 122. The ends of the two elastic pieces 1232 facing away from the connecting piece 1231 are curved and abut against the mounting seat 110. When the driving member 121 drives the pushing member 122 to rise, the pushing member 122 drives the connecting piece 1231 to rise, causing the two elastic pieces 1232 to move away from each other and open. When the driving member 121 is reset, the driving force of the driving member 121 on the pushing member 122 disappears, and the pushing force of the pushing member 122 on the connecting piece 1231 disappears. The two elastic members approach each other under their own elastic force and push the connecting piece 1231 and the pushing member 122 to reset.

[0090] The connecting piece 1231 and the two elastic pieces 1232 are integrally connected.

[0091] In this application, since the screw 1211, the nut 1212 and the handle 1213 all need to occupy installation space, the screw 1211, the nut 1212 and the handle 1213 are all installed on the back of the mounting base 110, and the two pushing plates 1221 of the pushing member 122 respectively pass through the mounting base 110 to extend from the back of the mounting base 110 to the front of the mounting base 110, thereby driving the clamping member 130.

[0092] Second, see Figures 1 to 4 The present application also provides a clamping device for clamping a light stick 2000. The clamping device includes a mounting plate 200 and at least two of the aforementioned clamping mechanisms 100. The at least two clamping mechanisms 100 are sequentially spaced apart on the mounting plate 200 along a second direction Y. The at least two clamping mechanisms 100 are used to clamp the light stick 2000 at different positions along its axis. The second direction Y is parallel to the axis of the installed light stick 2000.

[0093] The clamping device of the present application, through the provision of at least two clamping mechanisms 100, can clamp the lamp stick 2000 at different positions along the axial direction, thereby ensuring stable clamping of the lamp stick 2000. Furthermore, the clamping mechanisms 100 not only stably hold the lamp stick 2000, but also, because the clamping position is located on the rear housing of the lamp stick 2000, prevent light from being blocked.

[0094] In one embodiment, see Figure 1 The clamping device includes at least two sets of clamping mechanism assemblies, each set of which includes at least two clamping mechanisms 100 spaced apart along the second direction Y. Each set of clamping mechanism assemblies is used to clamp one light stick 2000. The at least two sets of clamping mechanism assemblies are spaced apart along the first direction X and are used to clamp at least two light sticks 2000. The clamping device of the present application, through the arrangement of at least two sets of clamping mechanism 100 assemblies, can simultaneously clamp at least two light sticks 2000, enabling the splicing of multiple lights to achieve different lighting effects.

[0095] In one embodiment, see Figure 1 The clamping device further includes at least two guide seats 300, which are arranged in a one-to-one correspondence with the at least two clamping mechanisms 100; each guide seat 300 is spaced apart from the corresponding clamping mechanism 100 along the second direction Y. The guide seats 300 are used to support the lamp stick 2000 and guide the lamp stick 2000 to pass through the corresponding clamping mechanism 100 along the second direction Y. In the present application, since only the clamping portion 131 of the clamping mechanism 100 abuts the lamp stick 2000, the clamping mechanism 100 cannot support and position the lamp stick 2000 in its installation position. However, the provision of the guide seats 300 can support the lamp stick 2000 beside the clamping mechanism 100 and simultaneously position the lamp stick 2000, thereby guiding the lamp stick 2000 to pass through the clamping mechanism 100.

[0096] Optionally, the clamping device includes two clamping mechanisms 100 and two guide seats 300, with the two guide seats 300 being located on opposite inner sides of the two clamping mechanisms 100, so that the lamp stick 2000 can be guided for installation by the two guide seats 300. It is understood that in other embodiments of the present application, depending on the axial length of the lamp stick 2000, the number of clamping mechanisms 100 and guide seats 300 may also be three, four, or four in sequence, and this is not intended to be a limitation.

[0097] In one embodiment, see Figure 1The guide base 300 is formed with an arcuate groove 310 extending along the second direction Y. The arcuate groove 310 is used to support the lamp stick 2000. Specifically, the inner wall of the arcuate groove 310 is used to abut against the outer wall of the bottom shell 2100 of the lamp stick 2000, thereby not only providing support and positioning, but also preventing the lamp stick 2000 from being blocked.

[0098] The arc groove 310 is a symmetrical structure along the first direction X, and the clamping mechanism 100 is also a symmetrical structure along the first direction X. The first symmetry plane of the arc groove 310 along the first direction X coincides with the second symmetry plane of the clamping mechanism 100 along the first direction X, so that the arc groove 310 and the clamping mechanism 100 can be completely opposite to each other along the first direction X. When the lamp stick 2000 is axially passed through the arc groove 310, the lamp stick 2000 can also axially pass through the clamping mechanism 100. Then, by appropriately adjusting the height of the arc groove 310, when the lamp stick 2000 is supported in the arc groove 310, the two clamping members 130 of the clamping mechanism 100 can also be clamped to the corresponding positions of the lamp stick 2000, thereby achieving the installation of the lamp stick 2000 on the clamping mechanism 100 guided by the guide seat 300.

[0099] In one embodiment, see Figure 2 , a soft rubber pad 320 is attached to the inner wall of the arc-shaped groove 310, wherein the soft rubber pad 320 can be a silicone pad or a rubber pad. During installation, the heat sinks on the outer wall of the bottom shell 2100 of the lamp stick 2000 respectively abut against the soft rubber pad 320. Through the provision of the soft rubber pad 320 in this embodiment, on the one hand, it can increase the friction between the guide seat 300 and the lamp stick 2000, prevent the lamp stick 2000 from sliding, and improve the installation reliability of the lamp stick 2000; on the other hand, because the soft rubber pad 320 is elastic, it can fill the gap between the bottom shell 2100 and the soft rubber pad 320, so that the bottom shell 2100 and the soft rubber pad 320 fit more tightly and the installation is more secure.

[0100] In one embodiment, see Figure 4 The clamping device also includes an angle adjustment structure 400, which is connected to the mounting plate 200. The angle adjustment structure 400 is used to adjust the angle of the mounting plate 200 and the lamp stick 2000 installed on the mounting plate 200. That is, the angle of the mounting plate 200 is adjusted by the angle adjustment structure 400, thereby adjusting the angle of the lamp stick 2000 installed on the mounting plate 200, and then the angles of multiple lamp sticks 2000 can be adjusted at the same time to achieve different lighting effects.

[0101] For details, please refer to Figure 10The angle adjustment structure 400 includes a first connector 410 and a second connector 420. The first connector 410 is mounted on the mounting plate 200 and is provided with a universal ball 412. The second connector 420 is used to connect to an external support structure and is formed with a spherical groove 421. The universal ball 412 is received in the spherical groove 421, and the universal ball 412 and the spherical groove 421 form a spherical pair. In this embodiment, the universal ball 412 on the first connector 410 and the spherical groove 421 on the second connector 420 form a spherical pair, thereby enabling the first connector 410 to be universally rotated relative to the second connector 420, thereby enabling universal angle adjustment of the mounting plate 200 and the light bar 2000 to achieve different lighting effects.

[0102] See also Figure 10 The first connecting member 410 is installed on the mounting plate 200 through the fixing plate 430. The first connecting member 410 also includes a connecting column 411, which is locked on the fixing plate 430 by a fastener, and a universal ball 412 is formed on the end of the connecting column 411 away from the fixing plate 430.

[0103] In one embodiment, see Figure 1 The mounting plate 200 is also provided with a handle 500, by which the mounting plate 200 and the structure thereon can be transported and transferred.

[0104] In a third aspect, the present application further provides a lighting device, comprising a light stick 2000 and the above-mentioned clamping device, wherein the clamping device is used to install and clamp the light stick 2000.

[0105] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
