Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] First see Figure 1The utility model provides a support frame 10 for supporting a shooting device to prevent the shooting device from shaking and affecting the shooting effect when the user is using the shooting device. By shooting with the support frame 10, the user can get the desired photography effect. The support frame 10 can be used in conjunction with the shooting device to adapt to a variety of usage scenarios. The support frame 10 can be unfolded in a variety of usage scenarios, and the user can switch between different usage methods according to usage requirements, and the user experience is good.

[0037] It should be noted that the shooting equipment is electronic devices such as mobile phones and cameras.

[0038] refer to Figure 2 and Figure 3 The support frame 10 includes a base 100, a leg 200 and a first elastic member 300. The number of the legs 200 is at least two. The plurality of legs 200 are rotatably connected to the base 100 so that the legs 200 can switch between an extended state and a retracted state. In the extended state, the support frame 10 can be placed on a work surface and used in conjunction with a photographing device for photographing. In the retracted state, the support frame 10 can be stored, and the storage volume is small, which is convenient for carrying. The first elastic member 300 is connected between the leg 200 and the base 100. When the leg 200 is rotated and the leg 200 is switched from the extended state to the retracted state, the first elastic member 300 accumulates elastic force. When the leg 200 is switched from the retracted state to the extended state, the first elastic member 300 releases the elastic force and the leg 200 is automatically extended.

[0039] It should be noted that, in this embodiment, the number of the legs 200 is set to three. In other embodiments, the number of the legs 200 can be set to four or five. Therefore, the utility model does not specifically limit the number of the legs 200.

[0040] It should be noted that the working surface is the position where the support frame 10 is fixed, and the working surface can be a photography position such as a desktop or the ground.

[0041] It should be noted that, in this embodiment, the first elastic member 300 is a torsion spring.

[0042] Continue to refer Figure 2 and Figure 3 The support frame 10 further includes a limit member 400, which is connected to the base body 100 and is rotatably connected to the legs 200. When the plurality of legs 200 are in a folded state, the limit member 400 magnetically attracts the legs 200 to maintain the folded state.

[0043] Among them, reference Figure 3 and Figure 4The leg 200 is provided with a first connecting portion 210, and the limiting member 400 is provided with a second connecting portion 410 corresponding to the number of the legs 200. At least one of the first connecting portion 210 and the second connecting portion 410 is a magnetic member, and the limiting member 400 drives the second connecting portion 410 to rotate until the second connecting portion 410 is misaligned or corresponds to the first connecting portion 210.

[0044] It should be noted that, in the unfolded state, the second connection part 410 is misaligned with the first connection part 210 , and the second connection part 410 is detached from the first connection part 210 ; in the folded state, the second connection part 410 corresponds to the first connection part 210 , and the second connection part 410 abuts against the first connection part 210 .

[0045] refer to Figure 3 and Figure 4 When the first connection part 210 and the second connection part 410 are aligned and abutted, the first connection part 210 and the second connection part 410 can be magnetically attracted to each other. When the stopper 400 rotates along the circumference of the seat body 100, the first connection part 210 and the second connection part 410 are circumferentially misaligned, and the second connection part 410 releases the restriction on the rotation of the first connection part 210, and the second connection part 410 is separated from the first connection part 210. By providing the first connection part 210 and the second connection part 410, the consumption of magnetic attraction materials can be reduced, and the overall weight of the support frame 10 can also be reduced, so that the user can carry the support frame 10 more conveniently.

[0046] In summary, in the present application, the stopper 400 can rotate relative to the leg 200 along the circumferential direction of the seat body 100. When using the support frame 10, it is only necessary to rotate the stopper 400 so that the stopper 400 drives the second connection part 410 to rotate until the second connection part 410 is separated from the first connection part 210. The leg 200 is automatically unfolded under the elastic force of the first elastic member 300, and the user does not need to open the legs 200 one by one and fix the legs 200 one by one, which is convenient for operation. The user does not need to put the support frame 10 in a vertical state to achieve automatic opening, and the user does not need to open the legs 200 one by one and fix the legs 200 one by one. The operation is convenient, one-button triggering is achieved, and the user experience is good.

[0047] refer to Figure 3The side wall of the base 100 is provided with a receiving groove 110, the first elastic member 300 is received in the receiving groove 110, and the leg 200 is installed between two opposite inner side walls of the receiving groove 110, and the shape of the receiving groove 110 is adapted to the shape of the leg 200. By providing the receiving groove 110, the structure of the base 100 is more compact, and the leg 200 is installed in the receiving groove 110, and the overall structure of the support frame 10 is more beautiful. It can be understood that, without considering the compactness and beauty of the structure, the receiving groove 110 may not be provided, and all solutions that can install the leg 200 on the base 100 should be protected.

[0048] It should be noted that when the legs 200 are unfolded, the legs 200 abut against the groove wall of the receiving groove 110 to limit the legs 200 from further unfolding relative to the base 100. When the legs 200 are unfolded, when the angle formed between the legs 200 and the base 100 reaches a preset angle, the legs 200 abut against the groove wall of the receiving groove 110. At this time, the support frame 10 is unfolded to the maximum extent, and the groove wall of the receiving groove 110 limits the legs 200 from further unfolding relative to the base 100. At this time, the support frame 10 can be stably placed on the work surface.

[0049] refer to Figure 4 It should be noted that the support leg 200 has a rotating end 220 and a supporting end 230, the rotating end 220 is rotatably connected to the base body 100, and the supporting end 230 is supported on the working surface.

[0050] refer to Figure 4 , a third mounting groove 231 is provided on the side of the support end 230 facing the limiter 400, and the third mounting groove 231 extends along the length direction of the support leg 200, and the support leg 200 is provided with a stabilizing structure 240, and the stabilizing structure 240 is accommodated in the third mounting groove 231, and the stabilizing structure 240 is provided with a supporting surface 241, and in the folded state, the normal of the supporting surface 241 is inclined to the height direction of the support frame 10, and in the unfolded state, the supporting surface 241 is perpendicular to the height direction of the support frame 10, and the supporting surface 241 contacts with the working surface to support the support frame 10. By providing the stabilizing structure 240, the supporting surface 241 can be in full contact with the working surface, so that the support frame 10 can be stably placed on the working surface. It can be understood that the stabilizing structure 240 may not be provided, as long as the solution that the support frame 10 can be placed on the working surface in the unfolded state should be protected.

[0051] It should be noted that, in this embodiment, the first connection part 210 is configured as a magnetic attraction member, the second connection part 410 is configured as a magnetic attraction member, and the second connection part 410 is magnetically attracted to the first connection part 210, so that the leg 200 is maintained in a folded state. When the first connection part 210 is configured as a magnetic attraction member, and the second connection part 410 is also configured as a magnetic attraction member, the magnetism of the first connection part 210 and the second connection part 410 are opposite.

[0052] It should be noted that, in other embodiments, the first connection part 210 is configured as a magnetic metal part, the second connection part 410 is configured as a magnetic attraction part, and the second connection part 410 is magnetically attracted to the first connection part 210, so that the support leg 200 is maintained in a folded state.

[0053] It should be noted that, in other embodiments, the first connection part 210 is configured as a magnetic member, the second connection part 410 is configured as a magnetic metal member, and the first connection part 210 is magnetically attracted to the second connection part 410, so that the support leg 200 is maintained in a folded state.

[0054] It should be noted that the magnetic metal part is a part made of magnetic metal materials such as iron, nickel or cobalt, and the magnetic metal part can be magnetically attracted by the magnetic part.

[0055] It should be noted that the leg 200 and the limit member 400 are not all set to magnetic materials or magnetic metal materials, so that the limit member 400 can rotate relative to the leg 200. Otherwise, the limit member 400 will firmly magnetically attract the leg, and the limit member 400 cannot release the restriction on the leg 200, and the support frame 10 cannot be used.

[0056] refer to Figure 3 and Figure 5 The stopper 400 is provided with a plurality of first mounting grooves 420, the first mounting grooves 420 extend along the height direction of the support frame 10, and the plurality of first mounting grooves 420 are arranged at intervals along the circumference of the stopper 400, the second connection portion 410 is accommodated in the first mounting grooves 420, the second connection portion 410 is fixedly connected to the stopper 400, the stopper 400 is rotated, and the second connection portion 410 can rotate with the rotation of the stopper 400, the first connection portion 210 and the second connection portion 410 are misaligned along the circumference of the seat body 100, and the leg 200 is automatically unfolded under the elastic force of the first elastic member 300. By providing the first mounting grooves 420, the second connection portion 410 is accommodated in the first mounting grooves 420, the structure of the stopper 400 is more compact, the second connection portion 410 is flush with the outer surface of the stopper 400, and the second connection portion 410 will not hit the leg 200, thereby limiting the storage angle of the leg 200, and increasing the aesthetics of the overall structure of the support frame 10. It is understandable that, without considering the compactness and aesthetics of the structure, the first mounting groove 420 may not be provided, and any solution in which the second connecting portion 410 is fixedly connected to the limiting member 400 should be protected.

[0057] It should be noted that the number of the first installation grooves 420 matches the number of the second connection portions 410 .

[0058] refer to Figure 3 and Figure 4 , a second mounting groove 221 is provided inside the rotating end 220, and the second mounting groove 221 extends along the height direction of the support frame 10, and the first connecting portion 210 is accommodated in the second mounting groove 221, and the first connecting portion 210 is magnetically attracted to the limiter 400, so that the legs 200 are close to each other to maintain the folded state. By providing the second mounting groove 221, the first connecting portion 210 is accommodated in the second mounting groove 221, and the first connecting portion 210 is flush with the outer surface of the leg 200. The first connecting portion 210 will not hinder the storage of the leg 200, and will not limit the storage angle of the leg 200, thereby increasing the aesthetics of the overall structure of the support frame 10. It can be understood that without considering the compactness and aesthetics of the structure, the second mounting groove 221 may not be provided, and any solution in which the first connecting portion 210 is fixedly connected to the leg 200 should be protected.

[0059] Continue to refer Figure 3 and Figure 5 The stopper 400 includes a plurality of first surfaces 430 and a plurality of second surfaces 440. The first surfaces 430 and the second surfaces 440 are arranged at intervals along the circumference of the stopper 400. An edge 431 is formed at the connection between the first surface 430 and the second surface 440. The first mounting groove 420 is formed on the first surface 430. The leg 200 contacts and cooperates with the first surface 430. When the stopper 400 rotates, the leg 200 is driven by the edge 431 to tilt outward along the radial direction of the stopper 400, so that the leg 200 switches from the folded state to the unfolded state under the action of the first elastic member 300. By forming the edge 431 at the connection between the first surface 430 and the second surface 440, when the stopper 400 rotates, the edge 431 can abut the leg 200, so that the leg 200 rotates outward along the radial direction of the stopper 400 to switch to the unfolded state. It is understandable that the edge 431 may not be provided, and any solution in which the leg 200 can be switched from the folded state to the unfolded state under the action of the first elastic member 300 should be protected.

[0060] refer to Figure 2 and Figure 3 The support frame 10 further includes a knob 500, which is sleeved on the outer side of the seat body 100 and fixedly connected to the stopper 400. By rotating the knob 500, the knob 500 can drive the stopper 400 to rotate along the circumferential direction of the seat body 100; Figure 6The knob 500 includes a plurality of rotation slots 510, which extend along the circumference of the base 100. The base 100 is provided with a fixing column 120, which passes through the rotation slots 510 and can rotate along the slot wall of the rotation slot 510. By providing the knob 500, the knob 500 is fixedly connected to the stopper 400, and the stopper 400 is driven to rotate by turning the knob 500. Moreover, the knob 500 is not covered by the leg 200, so the user can directly turn the knob 500 without having to put his hand into the inside of the retracted leg 200 to turn the stopper 400. The operation is convenient and the user experience is good. It is understandable that the knob 500 may not be provided. For example, the rotation of the limit member 400 is electrically controlled. When the user needs to use the support frame 10, he only needs to press the switch on the support frame 10, and the limit member 400 can automatically rotate. After the first connecting part 210 and the second connecting part 410 form a circumferential misalignment, the leg 200 switches from the folded state to the unfolded state. As long as the limit member 400 can rotate circumferentially along the seat body 100, it should be protected.

[0061] refer to Figure 2 and Figure 3 It should be noted that the outer wall of the knob 500 is provided with anti-slip grooves 520, which can effectively prevent the user from slipping when turning the knob 500. Compared with the solution without anti-slip grooves 520, the user can turn the knob 500 with less effort.

[0062] refer to Figure 2 and Figure 3 It should be noted that, in the present embodiment, the support frame 10 further includes a connecting shaft 600, one end of the connecting shaft 600 is connected to the knob 500, and the other end of the connecting shaft 600 is connected to the stopper 400 after passing through the seat 100, and the rotation of the knob 500 can drive the stopper 400 to rotate synchronously. By setting the connecting shaft 600, the connecting shaft 600 is connected to the stopper 400 after passing through the knob 500 and the seat 100, which is convenient for installation, and is also convenient for disassembly when the knob 500 needs to be replaced after a certain period of use. It can be understood that the connecting shaft 600 may not be set, as long as the solution of the stopper 400 and the knob 500 being fixedly connected should be protected.

[0063] refer to Figure 3The support frame 10 also includes a second elastic member 700, which is arranged between the base body 100 and the knob 500. The knob 500 includes a bottom plate 530. The above-mentioned rotation groove 510 is arranged on the bottom plate 530. A baffle 531 is also arranged on the side of the bottom plate 530 facing the support leg. The baffle 531 extends along the height direction of the support frame 10. The opposite ends of the second elastic member 700 are respectively abutted against the fixing column 120 and the baffle 531; the second elastic member 700 can overcome elastic deformation, so that the knob 500 rotates and returns to the position before being screwed. By setting the second elastic member 700, after the user has screwed the knob 500 and released the knob 500, the knob 500 and the stopper 400 return to their original positions under the action of the second elastic member 700. After the user has used the support frame 10, the user rotates the multiple legs 200 until the legs 200 are magnetically attracted to the stopper 400, and the storage of the support frame 10 is completed. The user does not need to rotate the stopper 400 first to return the stopper 400, and then rotate the multiple legs 200 to complete the storage of the support frame 10. By setting the second elastic member 700, the support frame 10 can be expanded and stored with one key, which is easy to operate and provides a good user experience. It can be understood that the second elastic member 700 may not be provided, and any solution in which the stopper 400 can return to its original position should be protected.

[0064] It should be noted that, in this embodiment, the second elastic member 700 is a torsion spring.

[0065] refer to Figure 2 and Figure 7 The support frame 10 also includes an adapter seat 800, which is arranged at one end of the knob 500 away from the seat body 100, and the adapter seat 800 and the seat body 100 form an installation space 810, and the base plate 530 is installed in the installation space 810; the knob 500 also includes a ring 540, which is connected to the base plate 530 and is sleeved on the outer side of the seat body 100 and the adapter seat 800. Since the bottom plate 530 is installed in the installation space 810, the knob 500 rotates along the circumference of the seat body 100. After the knob 500 is used for a certain period of time, it will inevitably be worn out, resulting in a gap when the knob 500 is installed in the installation space 810, resulting in the knob 500 and the seat body 100 being installed unstably, and the shooting equipment installed on the adapter 800 may shake slightly, resulting in poor photography effect. Therefore, in this embodiment, the adapter 800 and the seat body 100 are set to be detachably connected, and the adapter 800 can be removed and the knob 500 can be replaced when the knob 500 is used for a certain period of time, so as to ensure the service life of the entire support frame 10. Of course, without considering the service life, the adapter 800 and the seat body 100 can also be set to be non-detachably connected, for example, the adapter 800 and the seat body 100 are set to be an integrally formed structure, and any solution that the knob 500 can be installed in the installation space 810 should be protected.

[0066] When using the support frame 10, the user first turns the knob 500, and the knob 500 rotates along the circumference of the base body 100, so that the first connection portion 210 and the second connection portion 410 are circumferentially misaligned, and the legs 200 are automatically switched from the folded state to the unfolded state under the elastic force of the first elastic member 300. When the user releases the knob 500, the elastic force accumulated in the second elastic member 700 is released, and the knob 500 and the limit member 400 return to their original positions. At this time, the user places the support frame 10 on the work surface. After installing the shooting equipment, the support frame 10 can be used to take the required photos; when the user has finished using the support frame 10, the user first detaches the shooting equipment from the support frame 10, and then overcomes the elastic force of the first elastic member 300, pulls the multiple legs 200, so that the multiple legs 200 are magnetically attracted to the limiting member 400, and the multiple legs 200 are switched from the expanded state to the folded state, and the expansion of the legs 200 relative to the base 100 is limited by the limiting member 400, thereby completing the storage of the support frame 10.
