[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0037] The present invention provides a bracket 1000, such as Figure 1-3 As shown, the bracket 1000 includes a main rod 100, a slider 200, and a plurality of support leg assemblies 300 disposed around the main rod 100. The slider 200 is mounted on the main rod 100 and can slide relative to the main rod 100 along its length. Each support leg assembly 300 includes a support leg 310, a connecting rod 320, and a tension spring 330. One end of the support leg 310 is rotatably connected to the slider 200, allowing the support leg 310 to rotate relative to the main rod 100 to expand or retract. One end of the connecting rod 320 is rotatably connected to the main rod 100, and the other end is rotatably connected to the support leg 310, allowing the connecting rod 320 to expand or retract with the support leg 310. One end of the tension spring 330 is connected to the support leg 310 or the slider 200, and the other end is connected to the connecting rod 320. The tension spring 330 is used to deform and store energy when the support leg 310 is retracted, and to drive the support leg to expand when the energy is released.

[0038] Specifically, since one end of the tension spring 330 is connected to the supporting foot 310 or the slider 200, and the other end of the tension spring 330 is connected to the connecting rod 320, and when the supporting foot 310 is stored on the main rod 100, the tension spring 330 deforms and stores energy, and the tension spring 330 can enable the supporting foot 310 to rotate relative to the main rod 100 and thus open when releasing energy. It can be seen that by implementing this embodiment, the tension spring 330 can be used to drive the supporting foot 310 to automatically open, which simplifies the operation of the user when opening the bracket 1000, and the user experience is excellent.

[0039] It is worth noting that during the opening of the support legs 310, the connecting rod 320 needs to rotate relative to the support legs 310 and the main rod 100, and the slider 200 also needs to slide along the length of the main rod 100, so that the support legs 310 can be properly opened. Therefore, in this embodiment, the slider 200 is mounted on the main rod 100 and can slide along the length of the main rod 100. One end of the connecting rod 320 is rotatably connected to the main rod 100, and the other end is rotatably connected to the support legs 310.

[0040] refer to Figure 4 In a specific embodiment, one end of the tension spring 330 is connected to the side of the support foot 310 close to the slider 200, and the other end of the tension spring 330 is connected to the connection position of the connecting rod 320 (such as Figure 4 a position in the figure), and the connection position between the connecting rod 320 and the supporting foot 310 (as shown in FIG. Figure 4 With this arrangement, the lever arm will be longer, making it easier for the tension spring 330 to drive the connecting rod 320 and the supporting leg 310 to rotate.

[0041] Optionally, one end of the tension spring 330 is connected to the slider 200, and the other end of the tension spring 330 is connected to the connection position of the connecting rod 320 (such as Figure 4 a position in the figure), and the connection position between the connecting rod 320 and the supporting foot 310 (as shown in FIG. Figure 4 This also makes it easier for the tension spring 330 to drive the connecting rod 320 and the supporting foot 310 to rotate.

[0042] refer to Figure 5 In one embodiment, a receiving groove 311 is provided on the side of the support leg 310 facing the main pole 100. When the support leg 310 is in the stowed state, the connecting rod 320 and the tension spring 330 are both received in the receiving groove 311. With this arrangement, when the support leg 310 is in the stowed state, the connecting rod 320 can be hidden in the receiving groove 311, which helps reduce the volume of the stand 1000 and improve its portability.

[0043] refer to Figure 3 、 Figure 6 、 Figure 7In some embodiments, the bracket 1000 further includes a first screw (not shown). One end of the tension spring 330 includes a first connecting ring 331. An internally threaded column 312 is protruding from the bottom of the receiving groove 311. The first screw is inserted into the first connecting ring 331 and the internally threaded column 312. This arrangement allows one end of the tension spring 330 to be connected to the support leg 310. Since the internally threaded column 312 is protruding from the bottom of the receiving groove 311, even if the bottom of the receiving groove 311 is relatively thin, the first screw can still be used to connect the tension spring 330 to the support leg 310. In addition, using the first screw to connect the tension spring 330 to the support leg 310 has the beneficial effects of stable connection and low cost.

[0044] In some embodiments, the bracket 1000 further includes a first screw. One end of the tension spring 330 has a first connecting ring 331. The bottom of the receiving groove 311 is provided with a first threaded hole (not shown). The first screw is inserted between the first connecting ring 331 and the first threaded hole. This arrangement also allows one end of the tension spring 330 to be connected to the support leg 310. This embodiment utilizes a first screw to connect the tension spring 330 to the support leg 310, resulting in a stable connection and low cost.

[0045] refer to Figure 3 、 Figure 8 In some embodiments, the other end of the tension spring 330 has a second connecting ring 332, and a barb 321 is provided on the side of the connecting rod 320 close to the main rod 100. The barb 321 is bent in a direction away from the slider 200, and the barb 321 is hooked on the second connecting ring 332.

[0046] By implementing this embodiment, the tension spring 330 can be connected to the connecting rod 320 by simply inserting the second connecting ring 332 onto the barb 321 and hooking the second connecting ring 332 with the barb 321. It is worth mentioning that the barb 321 is bent away from the slider 200 because when the support leg 310 is stored, the tension spring 330 has stress in the direction toward the slider 200. To prevent the tension spring 330 from escaping from the opening 322 defined by the barb 321, the barb 321 of this embodiment is bent away from the slider 200.

[0047] refer to Figure 3 In some embodiments, the other end of the tension spring 330 has a second connecting ring 332. The connecting rod 320 has a lug (not shown) on the side close to the main rod 100. The lug has a first through hole 510 (not shown) in the lug, and the connecting ring is inserted into the first through hole 510. By implementing this embodiment, the second connecting ring 332 can be prevented from separating from the connecting rod 320 and causing product failure.

[0048] It is worth mentioning that Figure 8 As shown, a barb 321 can be first provided on the side of the connecting rod 320 close to the main rod 100, and after the second connecting ring 332 is put onto the barb 321, the opening 322 of the barb 321 is sealed. In this way, a lug with a first through hole 510 is formed in this embodiment. Since the opening 322 no longer exists, the second connecting ring 332 cannot be separated from the first through hole 510, which can effectively prevent the second connecting ring 332 from separating from the connecting rod 320 and causing product failure.

[0049] refer to Figure 9 In some embodiments, a first locking structure 410 is provided on the main rod 100, and a second locking structure 313 is provided on the supporting foot 310. The first locking structure 410 and the second locking structure 313 are used in conjunction with each other to lock the supporting foot 310 when the supporting foot 310 is stored.

[0050] By implementing this embodiment, the first locking structure 410 and the second locking structure 313 can be used to lock the support leg 310, effectively preventing the tension spring 330 from releasing energy to drive the support leg 310 to open when the support leg 310 is in the retracted state.

[0051] In some embodiments, the first locking structure 410 is engaged with the second locking structure 313 , and the first locking structure 410 and the second locking structure 313 can be disengaged by forcibly pulling the support leg 310 .

[0052] In some embodiments, the first locking structure 410 is magnetically connected to the second locking structure 313 , and the first locking structure 410 and the second locking structure 313 can be disconnected from the magnetic connection by forcibly pulling the support leg 310 .

[0053] refer to Figure 9 In some embodiments, the first locking structure 410 is engaged with the second locking structure 313, and the bracket 1000 also includes an unlocking button 400. The unlocking button 400 is installed on the main rod 100 and is connected to the first locking structure 410. The unlocking button 400 is used to drive the first locking structure 410 so that the first locking structure 410 and the second locking structure 313 are disengaged from the engagement relationship.

[0054] In this embodiment, even if a force acts on the support leg 310, the first locking structure 410 and the second locking structure 313 will not be disengaged, and the support leg 310 cannot be opened. Only by triggering the unlocking button 400 can the first locking structure 410 and the second locking structure 313 be engaged. Therefore, by implementing this embodiment, it is possible to prevent the first locking structure 410 and the second locking structure 313 from being disengaged due to external forces to a certain extent.

[0055] Optionally, an elastic band can be used to bind the support leg 310 so that the tension spring 330 cannot release energy. If the support leg 310 is needed, the tension spring 330 can be freed from the constraint by simply removing the elastic band, and the support leg 310 can be opened by releasing energy.

[0056] refer to Figure 9 、 Figure 10 In a specific embodiment, the unlocking button 400 is installed at the bottom of the main rod 100, and the side of the supporting foot 310 away from the slider 200 is provided with a narrowing portion 314 extending toward the unlocking button 400. The second locking structure 313 is a slot 3131 provided on the side of the narrowing portion 314 facing the slider 200, and the first locking structure 410 is a hook 411 adapted to the slot 3131.

[0057] By implementing this embodiment, when the unlock button 400 is pressed, the hook 411 will move toward the slider 200 until the hook 411 is disengaged from the slot 3131; at this time, the tension spring 330 will be disengaged from the constraints of the hook 411 and the slot 3131, thereby releasing energy and deforming, and finally driving the support leg 310 to rotate relative to the main rod 100 and open.

[0058] refer to Figure 9 In a specific embodiment, the unlock button 400 and the hook 411 are integrally formed, which can reduce the number of parts and reduce the mold opening and assembly costs. Therefore, by implementing this embodiment, the production cost can be effectively saved.

[0059] refer to Figure 9 In some embodiments, a mounting base 500 is fixedly provided at the bottom of the main lever 100, and one end of the connecting rod 320 is rotatably connected to the mounting base 500. The unlock button 400 is movably connected to the mounting base 500 in the direction in which it is pressed, and a compression spring (not shown) is installed between the unlock button 400 and the mounting base 500, so that the unlock button 400 can be reset under the drive of the compression spring.

[0060] refer to Figure 11 In a specific embodiment, a through hole 510 is provided on the mounting base 500 along the length direction of the main rod 100, and a pin 420 is provided on the side of the unlocking button 400 facing the slider 200 and passes through the through hole 510. A second threaded hole 421 is provided on the side of the pin 420 facing the slider 200. The bracket 1000 also includes a second screw 600, which is inserted into the second threaded hole 421, and the head size of the second screw 600 is larger than the through hole 510, so that the unlocking button 400 is movably connected to the mounting base 500 in its pressing direction.

[0061] Furthermore, the compression spring is sleeved on the latch 420, so that the position of the compression spring can be constrained by the latch 420, thereby preventing the compression spring from deviating from its position during repeated use, resulting in the unlock button 400 being unable to reset.

[0062] In some embodiments, the connecting rod 320 and / or the supporting leg 310 are made of aluminum alloy, so that the connecting rod 320 and / or the supporting leg 310 have good strength and hardness, and the aluminum alloy has a lower density, which is conducive to keeping the bracket 1000 lightweight and can effectively reduce the burden on the user when carrying it outside.

[0063] The present invention also provides an auxiliary shooting device (not shown in the figure), such as Figure 1-Figure 3 As shown, the auxiliary shooting device includes the bracket 1000 shown in the above embodiment. Therefore, when the user uses the auxiliary shooting device of this embodiment, the tension spring 330 can be used to drive the support leg 310 to automatically open, simplifying the user's operation when opening the bracket 1000, and providing an excellent user experience.

[0064] In some embodiments, a telescopic joint (not shown in the figure) is provided inside the main rod 100, so that the relative position of the shooting device installed on the auxiliary shooting device can be adjusted, which provides an excellent user experience.

[0065] It should be noted that the shooting device can be mounted on the auxiliary shooting device by clamping, by screwing, or by magnetic placement, which is not limited in this embodiment.

[0066] In some embodiments, the auxiliary shooting device further includes a remote controller (not shown in the figure) for wirelessly connecting to the shooting device, so that the user can use the remote controller to control the shooting device for shooting.

[0067] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
