Description

Technical Field

[0001] This utility model relates to the field of shooting auxiliary equipment technology, and in particular to a bracket and shooting auxiliary device. Background Technology

[0002] The support frame typically has multiple legs, forming an openable and foldable structure for easy carrying and use. To enhance the stability of the support structure after deployment, a support rib is often installed between the legs and the main rod. One end of the support rib is rotatably connected to the leg, while the other end can rotate relative to the main rod. The support rib connects the main rod and legs, allowing each leg to unfold or fold in unison as it slides relative to the main rod.

[0003] In the process of unfolding and using the existing support, when the legs of the support are slid to the bottom of the main rod relative to the main rod to the limit position (that is, when the support is in the supported state and all legs are fully unfolded), the legs will "bounce back" after reaching the limit position (that is, the legs will slide to the top of the main rod relative to the main rod), which will cause the legs of the support to not fully unfold and the support performance to be poor. Utility Model Content

[0004] This utility model provides a bracket and a shooting auxiliary device to solve the problem that during use, the support legs slide back on the main rod, causing the bracket's legs to not fully extend and resulting in poor support performance.

[0005] This utility model discloses a bracket, comprising: a main rod having a positioning protrusion; a support assembly slidably fitted onto the main rod along its length; and a support component including at least three legs, one end of each leg being rotatably connected to the support assembly. The support component further includes support ribs, each support rib being paired with a leg, one end of each support rib being rotatably connected to the main rod, and the other end being rotatably connected to a leg. The support assembly, when sliding along the main rod, can switch between a retracted and extended state. When the support component is in the extended state, the positioning protrusion abuts against the support assembly to prevent the support assembly from sliding towards the top of the main rod.

[0006] Optionally, at least two positioning protrusions are provided, and the positioning protrusions are distributed at intervals on the outer periphery of the main rod.

[0007] Optionally, two positioning protrusions are provided, and the two positioning protrusions are distributed radially along the main rod on opposite sides of the main rod.

[0008] Optionally, three positioning protrusions are provided, and the three positioning protrusions are evenly distributed on the outer periphery of the main rod.

[0009] Optionally, the support assembly includes interconnected support legs and sleeves, both of which are slidably connected to the main rod, and one end of each support leg is rotatably connected to the support leg. When the support assembly is in the retracted state, each support leg approaches each other and forms a space for storing the main rod and the sleeve. When the support assembly is in the extended state, the positioning protrusion abuts against the sleeve to prevent the support assembly from sliding towards the top of the main rod. The diameter of the sleeve is smaller than the diameter of the support leg.

[0010] Optionally, when the support assembly is in the unfolded state, the positioning protrusion abuts against the inner wall of the sleeve; a guide slope connects the positioning protrusion and the inner wall of the sleeve.

[0011] Optionally, the inner wall of the sleeve is provided with a limiting part, and when the support assembly is in the unfolded position, the positioning protrusion abuts against the limiting part.

[0012] Optionally, a sliding sleeve is provided at the end of the sleeve away from the support base, and part or all of the sliding sleeve is located between the sleeve and the main rod, with the positioning protrusion abutting against the sliding sleeve.

[0013] Optionally, the bracket further includes a locking element located at the bottom end of the main rod. The locking element is used to lock and unlock the support assembly. When the locking element is locked, the support assembly is retracted to the outer periphery of the main rod. When the locking element is unlocked, the support assembly can slide out along the main rod.

[0014] This utility model also discloses a shooting auxiliary device, including a clamping member and a bracket as described above, wherein the clamping member is disposed at the top of the main rod.

[0015] The beneficial effects of the bracket and shooting auxiliary device provided in this utility model embodiment are as follows: when the support component is in the unfolded state, the positioning protrusion abuts against the support component, and the friction between the two after abutting is used to fix the support component, preventing the support component from sliding back on the main rod (i.e. sliding towards the top of the main rod), thereby ensuring that each support leg can remain in the fully unfolded state after being fully unfolded, thus forming a stable support structure.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] This utility model embodiment provides a bracket, such as Figures 1 to 6 As shown, the assembly includes a main rod 10, a support assembly 20, and a support component. The main rod 10 is provided with a positioning protrusion 110. The support assembly 20 is slidably fitted onto the main rod 10 along its length. The support component includes at least three legs 310, one end of which is rotatably connected to the support assembly 20. The support component also includes support ribs 320, which are provided one-to-one with the legs 310 (i.e., the same number of each is provided). One end of each support rib 320 is rotatably connected to the main rod 10, and the other end is rotatably connected to the legs 310. The support assembly 20 can slide along the main rod 10 to switch between a retracted and an extended state. When the support component is in the extended state, the positioning protrusion 110 abuts against the support assembly 20 to prevent the support assembly 20 from sliding toward the top of the main rod 10.

[0027] In this embodiment, the support assembly 20 is slidably fitted onto the main rod 10 along its length, allowing the support assembly 20 to be adjusted in position on the main rod 10, thus enabling the support assembly to switch between unfolding and retracting. The support assembly consists of a support leg 310 and a support rib 320. The support leg 310 is rotatably connected to the support assembly 20, allowing the support leg 310 to rotate about its connection point with the support assembly 20, thus enabling unfolding and retracting actions. One end of the support rib 320 is rotatably connected to the main rod 10, and the other end is rotatably connected to the support leg 310, forming a linkage structure. When the support assembly is in the unfolded state, the positioning protrusion 110 abuts against the support assembly 20, using the frictional force between them to fix the support assembly 20, preventing it from sliding back on the main rod 10 (i.e., sliding towards the top of the main rod 10), thereby ensuring that each support leg 310 remains in the fully unfolded state after unfolding, thus forming a stable support structure. In this embodiment, the positioning protrusion 110 is disposed on the main rod 10. After the positioning protrusion 110 abuts against the support assembly 20, the positions of the support assembly 20 and the main rod 10 are relatively fixed. The friction generated after the positioning protrusion 110 abuts against the support assembly 20 prevents the support assembly 20 from sliding back on the main rod 10. In the prior art, when each leg 310 of the bracket is fully extended, the support assembly 20 will abut against the bottom end of the main rod 10 because it is in the extreme position. During the abutment process, it will spring back (i.e., the support assembly 20 will slide towards the top end of the main rod 10), which means that after the prior art bracket is extended, the legs 310 cannot be fully extended due to the springback.

[0028] As a preferred embodiment, at least two positioning protrusions 110 are provided, and the positioning protrusions 110 are distributed at intervals on the outer periphery of the main rod 10.

[0029] The multiple positioning protrusions 110 allow for positioning and fixing of the support assembly 20 from multiple locations, providing a more reliable fixation compared to a single positioning protrusion 110. Their spaced distribution around the outer periphery of the main rod 10 ensures a more uniform positioning force on the support assembly 20, avoiding the risk of fixation failure due to uneven force on a single positioning protrusion 110. This makes the support assembly 20 more securely fixed to the main rod 10, effectively preventing slippage during use. Ultimately, this improves the overall stability and reliability of the support system.

[0030] As a preferred embodiment, two positioning protrusions 110 are provided, and the two positioning protrusions 110 are distributed radially along the main rod 10 on opposite sides of the main rod 10.

[0031] Among them, two positioning protrusions 110 are radially distributed on opposite sides of the main rod 10, so that when the positioning protrusions 110 abut against the support assembly 20, they provide a symmetrical and balanced positioning force for the support assembly 20, further improving the stability of the positioning protrusions 110 in fixing the support assembly 20 and ensuring the support stability when the support assembly is deployed.

[0032] As a preferred embodiment, refer to Figure 3 There are three positioning protrusions 110, which are evenly distributed on the outer periphery of the main rod 10.

[0033] Among them, the three positioning protrusions 110 evenly distributed around the main rod 10 provide a balanced positioning force for the support assembly 20 when the positioning protrusions 110 abut against the support assembly 20, further improving the stability of the positioning protrusions 110 in fixing the support assembly 20 and ensuring the support stability when the support assembly is deployed.

[0034] As a preferred embodiment, refer to Figure 3 The support assembly 20 includes interconnected support feet 210 and sleeves 220. Both support feet 210 and sleeves 220 are slidably connected to the main rod 10, and one end of each support foot 310 is rotatably connected to the support foot 210. When the support assembly is in the retracted state, each support foot 310 approaches each other and forms a space for the main rod 10 and sleeves 220 to be stored. When the support assembly is in the extended state, the positioning protrusion 110 abuts against the sleeve 220 to prevent the support assembly 20 from sliding towards the top of the main rod 10. The diameter of the sleeve 220 is smaller than the diameter of the support foot 210.

[0035] The support assembly 20 consists of interconnected support feet 210 and sleeves 220. This structural design divides the support assembly 20 into two parts. The support feet 210 are mainly used to connect the legs 310, providing support and connection points for the rotation of the legs 310. The sleeves 220, when the support assembly is deployed, cooperate with the positioning protrusions 110 on the main rod 10 to fix the support assembly 20. The diameter of the sleeves 220 is smaller than the diameter of the support feet 210, so that the sleeves 220 can be housed within the space formed by the legs 310 when they are close together.

[0036] In this embodiment, the support 210 and the sleeve 220 can be either an integral structure or a separate structure, as shown in the reference. Figure 1 An example is given where the support 210 and the sleeve 220 are separate structures. The connection between the support 210 and the sleeve 220 can be a plug-in connection, which is not specifically limited here.

[0037] As a preferred embodiment, when the support component is in the unfolded state, the positioning protrusion 110 abuts against the inner wall of the sleeve 220; a guide slope 111 is connected between the positioning protrusion 110 and the inner wall of the sleeve 220.

[0038] See Figure 3 and Figure 4 The positioning protrusion 110 abuts against the inner wall of the sleeve 220, meaning that all or part of the positioning protrusion 110 can extend into the sleeve 220, thereby achieving abutment against the inner wall of the sleeve 220. This abutment includes direct abutment between the positioning protrusion 110 and the inner wall of the sleeve 220, or indirect abutment achieved by providing other components between them. See also... Figure 5 and Figure 6 The guide slope 111 is used to guide the sleeve 220 to abut against the positioning protrusion 110 when it slides on the main rod 10. Specifically, the guide slope 111 can be provided on the positioning protrusion 110. During the process of the inner wall of the sleeve 220 abutting against the positioning protrusion 110, the guide slope 111 gradually reduces the distance between the two until they abut against each other, thus making the abutting process smoother. Similarly, a guide slope can also be provided on the inner wall of the sleeve 220 to make the process of the positioning protrusion 110 abutting against the inner wall of the sleeve 220 smoother.

[0039] As a preferred embodiment, refer to Figure 3 and Figure 4 The inner wall of the sleeve 220 is provided with a limiting part 221. When the support assembly is in the unfolded position, the positioning protrusion 110 abuts against the limiting part 221. Figure 4 In this embodiment, the positioning protrusion 110 directly abuts against the inner wall of the sleeve 220, and the limiting part 221 is part of the sleeve 220.

[0040] In a preferred embodiment, a sliding sleeve (not shown in the figure) is also provided inside the sleeve 220, and the sliding sleeve is slidably connected to the main rod 10. A sliding sleeve (not shown in the figure) is also provided at the end of the sleeve 220 away from the support 210, and part or all of the sliding sleeve is located between the sleeve 220 and the main rod 10, with the positioning protrusion 110 abutting against the sliding sleeve. In this embodiment, the positioning protrusion 110 and the inner wall of the sleeve 220 are indirectly abutted, and the abutment between the positioning protrusion 110 and the inner wall of the sleeve 220 is achieved through the sliding sleeve. It should be understood that the arrangement and fixing method of the sleeve 220 and the sliding sleeve are relatively conventional in the art and will not be described in detail here.

[0041] As a preferred embodiment, refer to Figure 1 and Figure 2The bracket also includes a locking element 40, which is located at the bottom end of the main rod 10. The locking element 40 is used to lock and unlock the support assembly. When the locking element 40 is locked, the support assembly is retracted to the outer periphery of the main rod 10. When the locking element 40 is unlocked, the support assembly can slide along the main rod 10 and be in an extended state. The locking element 40 provides a more reliable and convenient way to control the extension and retraction of the bracket, allowing users to easily switch the bracket between different states by operating the locking element 40. The locking element 40 in this embodiment can adopt an existing structure, which will not be described in detail here.

[0042] As a preferred embodiment, see [link to previous document]. Figure 2 and Figure 3 A spring 60 can be installed inside the sleeve 220. When the support assembly is retracted to the outer periphery of the main rod 10, the spring 60 accumulates elastic potential energy. Thus, when the locking element 40 is unlocked, the support assembly can slide along the main rod 10 under the action of the elastic potential energy, thereby realizing the automatic deployment of the support assembly. The specific setting of the spring 60 can adopt existing structures, which will not be described in detail here.

[0043] This utility model also provides a shooting assistance device, including a clamping member 50 and a bracket as described above, with the clamping member 50 disposed at the top of the main rod 10. Specifically, the shooting assistance device includes selfie sticks, handheld stabilizers, and other devices that can assist in shooting. The clamping member 50 adopts an existing structure and is used to clamp shooting devices such as mobile phones, tablets, and cameras.

[0044] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
