Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a support foot pad structure and an automatically pop-out bracket using the same. Background Technology

[0002] In the field of tripod technology, retractable and deployable tripod structures are widely used in shooting equipment, support devices, and other scenarios. When users need quick access, some automatically deployable tripods can automatically unfold their legs with a simple operation (such as placing them on the ground) to achieve rapid support. However, in existing technologies, during the automatic unfolding process, sliding friction occurs between the bottom of the legs and the contact surface (such as the ground, tabletop, etc.), leading to frequent wear on the bottom of the legs. After long-term use, the wear of the legs will disrupt the balance and stability of the tripod, affecting its support function and even causing the tripod to malfunction. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a foot pad structure, which isolates the foot body from the contact surface, avoids direct friction wear of the foot during the unfolding, retraction or movement of the support, significantly improves the durability of the foot, and ensures the balance and stability of the support for long-term use.

[0004] This utility model also proposes an automatically pop-out bracket with the above-mentioned support foot pad structure.

[0005] According to a first aspect embodiment of the present invention, the support foot pad structure includes a support foot and a foot pad, wherein the bottom of the support foot is provided with an inwardly recessed mounting groove; the foot pad is disposed in the mounting groove, and the end of the foot pad protrudes from the bottom of the support foot.

[0006] According to the support foot pad structure of this utility model embodiment, the following beneficial effects can be achieved: The bottom of the support foot has an inwardly recessed mounting groove for assembling the foot pad, and the end of the foot pad protrudes from the bottom of the support foot, making the foot pad a component that directly contacts the contact surface (such as the ground or tabletop). This design isolates the support foot body from the contact surface, avoiding direct friction wear of the support foot during the unfolding, retraction, or movement of the bracket, significantly improving the durability of the support foot and ensuring the balance and stability of the bracket for long-term use. After the foot pad wears out, it can be directly replaced without replacing the support foot, reducing maintenance costs.

[0007] According to some embodiments of the present invention, the support leg and the foot pad are provided with limiting parts, and the support leg and the foot pad are detachably connected through the limiting parts.

[0008] According to some embodiments of the present invention, the inner sidewall of the mounting groove is provided with a limiting protrusion, and the foot pad is provided with a matching limiting hole at a corresponding position. The limiting protrusion is inserted into the limiting hole, and the foot pad is detachably installed in the mounting groove.

[0009] According to some embodiments of the present invention, a positioning hole is provided on the bottom wall of the mounting groove, and a matching positioning protrusion is provided on the foot pad at the corresponding position. The positioning protrusion is inserted into the positioning hole, so that the foot pad can be detachably installed in the mounting groove.

[0010] According to some embodiments of the present invention, the foot pad protrudes from the bottom of the support foot and covers the bottom of the support foot.

[0011] According to some embodiments of the present invention, the foot pad is made of an elastic material.

[0012] The automatically retractable bracket according to a second aspect of the present invention includes a main rod, a locking assembly, a retractable member, and a foot pad structure according to a first aspect of the present invention. The top of the foot is rotatably connected to the main rod. The locking assembly is used to restrict the movement of the foot relative to the main rod when the foot is retracted onto the main rod, and the locking assembly releases the restriction after being triggered. After the locking assembly is triggered, the retractable member drives the bottom of the foot away from the main rod and fully unfolds the foot.

[0013] The automatically retractable bracket according to this embodiment of the invention achieves at least the following beneficial effects: the top of the support leg is rotatably connected to the main rod, forming an automatically retractable bracket system in conjunction with the locking assembly and the retracting component. The foot pad, a key component of the support leg, is installed in the mounting groove at the bottom of the support leg, ensuring both the compactness of the support leg when retracted and providing a stable support base after retraction. When the locking assembly is triggered to release the restriction, the retracting component drives the bottom of the support leg away from the main rod, and the foot pad simultaneously contacts the ground. Its protruding design preferentially absorbs impact force, preventing a hard collision between the support leg body and the contact surface, thus protecting structural integrity.

[0014] The protruding design of the feet cushions the outriggers during deployment, reducing vibration and noise. Simultaneously, the stable contact area ensures quick positioning of the outriggers after deployment, preventing incomplete deployment or tipping due to slippage. Once the locking mechanism is released, the spring-loaded mechanism drives the outriggers via a mechanical structure (such as springs or leaf springs). The feet, acting as end-support components, provide reverse friction during the spring-loaded process, assisting the outriggers in quickly and stably deploying to their working position, improving user convenience and reliability.

[0015] According to some embodiments of this utility model, the locking component includes a trigger button, one end of which is used to receive external force pressing, and the other end is provided with a locking structure; when the support leg is retracted onto the main rod, the locking structure abuts against the support leg, restricting the support leg from opening; when the trigger button is pressed by external force, the locking structure moves, releasing the restriction on the support leg.

[0016] According to some embodiments of this utility model, when the trigger button is pressed by an external force, it drives the locking structure to move along the axial direction of the main rod, thereby releasing the restriction on the support foot; the bottom of the foot pad is provided with a receiving groove to accommodate the movement of the trigger button.

[0017] According to some embodiments of this utility model, the side wall of the trigger button is provided with a plurality of spring pieces corresponding to the support foot, and the inner side wall of the foot pad is provided with an inclined abutment surface adapted to the spring pieces. When the trigger button moves along the axial direction of the main rod, it drives the spring pieces to contact the abutment surface and pushes the support foot outward.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] The following is for reference. Figures 1 to 7 This invention describes the support foot pad structure and the automatically pop-out bracket according to embodiments of the present invention.

[0034] According to the first aspect of the present invention, the support foot pad structure includes a bracket and a foot pad 300. The bottom of the support 200 is recessed with an installation groove 210. The foot pad 300 is disposed in the installation groove 210, and the end of the foot pad 300 protrudes from the bottom of the support 200.

[0035] For example Figure 1 and Figure 2 As shown, the support leg 200 serves as the main supporting structure, and its bottom mounting groove 210 provides mounting space for the foot pad 300. The foot pad 300 adopts a shape that fits the mounting groove 210, ensuring that it can be stably installed in the mounting groove 210. At the same time, its end, that is, the protrusion 350, protrudes from the bottom of the support leg 200, so that the foot pad 300 becomes a component that directly contacts the contact surface during the use of the bracket.

[0036] For example Figure 6 and Figure 7 As shown, the protrusion 350 of the foot pad 300 protrudes from the bottom of the support leg 200. That is, when the support is in the retracted state, the protrusion 350 of the foot pad 300 is located at the lowest point of the entire support, rather than the bottom of the support leg 200 being located at the lowest point of the entire support. Without the foot pad, the bottom of the support leg 200 would rub against the contact surface during the spring-opening process, causing wear. However, with the foot pad 300 installed, during the spring-opening process of the support leg 200, the protrusion 350 of the foot pad 300 contacts the contact surface and slides. After the support leg 200 is fully extended, the side of the foot pad 300 contacts the contact surface, providing support for the entire support.

[0037] By placing the foot pad 300 within the mounting groove 210 at the bottom of the support leg 200, and ensuring that the end of the foot pad 300 protrudes from the bottom of the support leg 200, isolation is achieved between the support leg 200 body and the contact surface. This ensures that during the deployment, retraction, or movement of the support, the contact surface contacts the foot pad 300, preventing direct frictional wear between the support leg 200 body and the contact surface, significantly improving the durability of the support leg 200. Furthermore, when the foot pad 300 wears out, only the foot pad 300 needs to be replaced, eliminating the need to replace the entire support leg 200, reducing maintenance costs and ensuring the long-term balance and stability of the support.

[0038] In some specific embodiments of this utility model, the support leg 200 and the foot pad 300 are provided with limiting parts, and the support leg 200 and the foot pad 300 are detachably connected through the limiting parts.

[0039] For example Figure 2 , Figure 3 and Figure 4 As shown, the support leg 200 and the foot pad 300 are detachably connected by a limiting part.

[0040] Specifically, the limiting part can take various forms. For example, a limiting protrusion 211 can be provided on the inner side wall of the mounting groove 210, and a matching limiting hole 310 can be provided at the corresponding position of the foot pad 300. The limiting protrusion 211 can be inserted into the limiting hole 310, thereby detachably installing the foot pad 300 in the mounting groove 210. Alternatively, a positioning hole 212 can be provided on the bottom wall of the mounting groove 210, and a matching positioning protrusion 320 can be provided on the foot pad 300 at the corresponding position. The positioning protrusion 320 can be inserted into the positioning hole 212, thereby realizing the detachable connection between the foot pad 300 and the support leg 200.

[0041] The limiting part allows for a detachable connection between the foot pad 300 and the support leg 200. This design facilitates the installation and removal of the foot pad 300. When the foot pad 300 wears out and needs to be replaced, the old foot pad 300 can be quickly and easily removed and a new foot pad 300 installed, improving maintenance convenience. It also ensures that the foot pad 300 will not easily fall out of the mounting groove 210 of the support leg 200 during use, thus ensuring the stability of the bracket support.

[0042] In some specific embodiments of this utility model, the inner sidewall of the mounting groove 210 is provided with a limiting protrusion 211, and the foot pad 300 is provided with a matching limiting hole 310 at the corresponding position. The limiting protrusion 211 is inserted into the limiting hole 310, and the foot pad 300 is detachably installed in the mounting groove 210.

[0043] For example Figure 3 and Figure 4 As shown, the inner sidewall of the mounting groove 210 is provided with a limiting protrusion 211, and the foot pad 300 is provided with a matching limiting hole 310 at the corresponding position. The limiting protrusion 211 is inserted into the limiting hole 310, so that the foot pad 300 can be detachably installed in the mounting groove 210.

[0044] When machining the support leg 200, raised limiting protrusions 211 are machined on the inner sidewall of the mounting groove 210. Multiple limiting protrusions 211 can be evenly distributed on the inner sidewall of the mounting groove 210. Simultaneously, when manufacturing the foot pad 300, matching limiting holes 310 are formed on the edge of the foot pad 300 according to the position and shape of the limiting protrusions 211. When installing the foot pad 300, it is aligned with the mounting groove 210, allowing the limiting protrusions 211 to insert into the limiting holes 310, thereby fixing the foot pad 300 within the mounting groove 210.

[0045] By engaging the limiting protrusion 211 with the limiting hole 310, the movement of the foot pad 300 within the mounting groove 210 is effectively restricted, ensuring that the foot pad 300 is securely installed within the mounting groove 210 of the support leg 200. This limiting structure is simple, reliable, and easy to manufacture. Moreover, during disassembly, only a slight force is needed to pull the foot pad 300 out of the mounting groove 210, which separates the limiting protrusion 211 from the limiting hole 310, facilitating the replacement of the foot pad 300 and further improving the practicality and maintainability of the support leg foot pad structure.

[0046] In some specific embodiments of this utility model, a positioning hole 212 is provided on the bottom wall of the mounting groove 210, and a matching positioning protrusion 320 is provided on the foot pad 300 at the corresponding position. The positioning protrusion 320 is inserted into the positioning hole 212, and the foot pad 300 is detachably installed in the mounting groove 210.

[0047] For example Figure 3 and Figure 4 As shown, a positioning hole 212 is provided on the bottom wall of the mounting groove 210. A matching positioning protrusion 320 is provided on the foot pad 300 at a corresponding position. The positioning protrusion 320 is inserted into the positioning hole 212, allowing the foot pad 300 to be detachably installed in the mounting groove 210. Positioning holes 212 are machined on the bottom wall of the mounting groove 210 of the support leg 200. There can be one or more positioning holes 212, positioned at appropriate locations on the bottom wall as needed. Simultaneously, a positioning protrusion 320 matching the positioning hole 212 is provided on the bottom of the foot pad 300. The shape and size of the positioning protrusion 320 match the positioning hole 212. During installation, the positioning protrusion 320 of the foot pad 300 is aligned with the positioning hole 212 of the mounting groove 210, and the foot pad 300 is pressed firmly into the mounting groove 210, causing the positioning protrusion 320 to insert into the positioning hole 212, thereby achieving the positioning and fixing of the foot pad 300.

[0048] The engagement of the positioning protrusion 320 and the positioning hole 212 ensures accurate positioning of the foot pad 300 during installation, guaranteeing its correct placement within the mounting groove 210. This structure also effectively prevents the foot pad 300 from moving vertically within the mounting groove 210, enhancing the connection stability between the foot pad 300 and the support leg 200. Similar to the structures of the limiting protrusion 211 and the limiting hole 310, this positioning structure facilitates the removal and replacement of the foot pad 300. Replacement is achieved simply by applying external force to remove the foot pad 300 from the mounting groove 210, reducing maintenance costs.

[0049] In some specific embodiments of this utility model, the foot pad 300 protrudes from the bottom of the support leg 200 and covers the bottom of the support leg 200.

[0050] The foot pad 300 is designed to cover the entire area of ​​the bottom of the support leg 200, with its edges extending outwards to form a wrapping structure around the bottom of the support leg 200. For example, the foot pad 300 can be designed in a bowl or basin shape, with its internal space adapted to the shape of the bottom of the support leg 200. When the foot pad 300 is installed in the mounting groove 210, the edge of the foot pad 300 extends beyond the edge of the bottom of the support leg 200, completely wrapping around the bottom of the support leg 200.

[0051] The design of the foot pads 300 covering the bottom of the support legs 200 ensures that all parts of the bottom of the support legs 200 are covered, completely avoiding direct contact between the support leg 200 body and the contact surface, further enhancing the protection of the support legs 200. At the same time, the covering structure increases the contact area between the foot pads 300 and the contact surface, making the bracket more stable when supported and reducing the possibility of the bracket wobbling or tipping over due to insufficient contact area. In addition, this covering design can also prevent dust, debris, etc., from entering the gap between the bottom of the support legs 200 and the mounting groove 210, keeping the bracket clean and in good working condition.

[0052] In some specific embodiments of this utility model, the foot pad 300 is made of an elastic material.

[0053] Elastic materials can be selected from materials with good elasticity and wear resistance, such as rubber, plastic, and silicone. These materials have a certain degree of elastic deformation capability, and can undergo slight deformation when subjected to pressure, thereby better adapting to the unevenness of the contact surface, increasing the friction between the contact surface, and making the support of the bracket more stable.

[0054] The foot pads 300, made of elastic material, have excellent cushioning properties. When the bracket is deployed or subjected to external impact, they can absorb part of the impact force, reducing impact damage to the legs 200 and the main body of the bracket. Simultaneously, the elastic material has good wear resistance, extending the service life of the foot pads 300. Furthermore, the use of elastic material can reduce noise generation during bracket movement, improving the user experience. Because of the elasticity of the foot pads 300, when installed in the mounting groove 210, they can fit tightly against the groove through their own elastic deformation, further enhancing the stability of the installation.

[0055] The automatically opening bracket according to the second aspect of the present invention includes a main rod 100, a locking component, a spring-opening component, and a foot pad structure according to the first aspect of the present invention. The top of the foot 200 is rotatably connected to the main rod 100. The locking component is used to restrict the movement of the foot 200 relative to the main rod 100 when the foot 200 is retracted onto the main rod 100, and the locking component releases the restriction after being triggered. After the locking component is triggered, the spring-opening component drives the bottom of the foot 200 away from the main rod 100 and causes the foot 200 to fully unfold.

[0056] For example Figure 1 and Figure 5 As shown, the main rod 100 serves as the main support structure of the bracket. The support legs 200 are connected to the main rod 100 via a rotating connection structure at the top, allowing the support legs 200 to rotate around the main rod 100 and switch between retracted and extended states. The locking assembly can be a mechanical structure, such as a buckle or spring lock. When the support legs 200 are retracted, the locking assembly locks them onto the main rod 100, preventing them from automatically extending. When the bracket needs to be extended, the locking assembly is triggered to release the restriction on the support legs 200. The spring-loaded component can be a spring, a spring plate 410, or other component with elastic potential energy. After the locking assembly releases the restriction, the spring-loaded component releases energy, driving the bottom of the support legs 200 to move outward, causing the support legs 200 to rotate around the rotating connection point and eventually fully extend.

[0057] The use of foot pads in the self-opening bracket ensures that the foot pads 300 at the bottom of the leg 200 remain in contact with the contact surface during expansion and contraction, preventing direct wear on the leg 200 itself. The top of the leg 200 is rotatably connected to the main rod 100, forming a self-opening bracket system in conjunction with the locking assembly and the spring-loaded mechanism. When the locking assembly is triggered to release the restriction, the spring-loaded mechanism drives the bottom of the leg 200 away from the main rod 100, and the foot pads 300 simultaneously contact the ground. Because the foot pads 300 protrude from the bottom of the leg 200, they preferentially absorb impact forces, preventing a hard collision between the leg 200 and the contact surface, thus protecting the integrity of the bracket structure. Simultaneously, the foot pads 300 provide a stable support base for the leg 200, ensuring the bracket can stably support the load after expansion.

[0058] In some specific embodiments of this utility model, the locking component includes a trigger button 400, one end of which is used to receive external force pressing, and the other end is provided with a locking structure 420; when the support leg 200 is retracted onto the main rod 100, the locking structure 420 locks the support leg 200, preventing the support leg 200 from opening; when the trigger button 400 is pressed by external force, the locking structure 420 moves, releasing the restriction on the support leg 200.

[0059] For example Figure 1 and Figure 5 As shown, the locking assembly includes a trigger button 400. One end of the trigger button 400 is used to receive external force pressing, and the other end is provided with a locking structure 420. When the support leg 200 is retracted onto the main rod 100, the locking structure 420 and the support leg 200 abut against each other, restricting the support leg 200 from opening. When the trigger button 400 is pressed by external force, the locking structure 420 moves, releasing the restriction on the support leg 200.

[0060] The trigger button 400 is located on the outside of the main rod 100 for easy user operation. One end of the trigger button 400 extends to the outside of the main rod 100, forming a pressing part. The user can trigger the unlocking action of the locking component by pressing this pressing part. The other end of the trigger button 400 is located inside the main rod 100 or connected to the internal structure of the main rod 100, and is provided with a locking structure 420, such as a hook or a slot. When the support leg 200 is retracted onto the main rod 100, the locking structure 420 and the corresponding structure on the support leg 200, such as a locking hole or a protrusion, cooperate to lock the support leg 200 and prevent it from unfolding. When the user presses the trigger button 400, the trigger button 400 drives the locking structure 420 to move, causing the locking structure 420 to separate from the corresponding structure on the support leg 200, releasing the restriction on the support leg 200. At this time, the pop-out component can then drive the support leg 200 to unfold.

[0061] The trigger button 400 allows users to unlock and unfold the bracket with a simple press, making operation convenient and efficient. The locking structure 420 reliably locks the legs 200 when they are retracted, ensuring that the legs 200 will not accidentally unfold during transportation or storage. When needed, simply pressing the trigger button 400 quickly unlocks the bracket, causing it to automatically spring open, improving the user experience. This locking component has a simple structure, high reliability, and is easy to manufacture and assemble.

[0062] In some specific embodiments of this utility model, when the trigger button 400 is pressed by an external force, it drives the locking structure 420 to move along the axial direction of the main rod 100, thereby releasing the restriction on the support foot 200; the bottom of the foot pad 300 is provided with a receiving groove 340 to accommodate the movement of the trigger button 400.

[0063] For example Figure 2 and Figure 5 As shown, the trigger button 400 and the locking structure 420 are designed to move in the axial direction of the main rod 100. When the user presses the trigger button 400, the trigger button 400 moves downward or upward along the axial direction of the main rod 100, causing the locking structure 420 to move synchronously, thus separating the locking structure 420 from the locking structure on the foot 200 and releasing the restriction on the foot 200. In order not to affect the normal use of the foot pad 300 and its contact with the contact surface, a receiving groove 340 adapted to the moving path of the trigger button 400 is provided on the bottom of the foot pad 300. The size and shape of the receiving groove 340 are such that the trigger button 400 will not interfere with the foot pad 300 during movement.

[0064] The design of the trigger button 400, which moves axially along the main rod 100, makes the unlocking action of the locking component smoother and more stable, accurately releasing the restriction on the support foot 200. The receiving groove 340 at the bottom of the foot pad 300 provides space for the movement of the trigger button 400, ensuring that the trigger button 400 is not obstructed by the foot pad 300 during movement, while also maintaining close contact between the foot pad 300 and the contact surface, thus ensuring the stability of the support. This compact structural design makes efficient use of the space at the bottom of the foot pad 300, optimizing the overall structure of the support.

[0065] In some specific embodiments of this utility model, the side wall of the trigger button 400 is provided with a plurality of spring pieces 410 corresponding to the support foot 200, and the inner side wall of the foot pad 300 is provided with an inclined abutment surface 330 adapted to the spring piece 410. When the trigger button 400 moves along the axial direction of the main rod 100, it drives the spring piece 410 to contact the abutment surface 330, pushing the support foot 200 outward.

[0066] For example Figure 2 and Figure 5 As shown, multiple spring pieces 410 are provided on the side wall of the trigger button 400. The number of spring pieces 410 corresponds to the number of support legs 200, with each spring piece 410 corresponding to one support leg 200. An inclined abutment surface 330 is provided on the inner side wall of the foot pad 300, and the inclination direction of the abutment surface 330 is adapted to the unfolding direction of the support leg 200. When the trigger button 400 moves axially along the main rod 100, the spring pieces 410 move together with the trigger button 400. When the spring pieces 410 contact the inclined abutment surface 330 of the inner side wall of the foot pad 300, the spring pieces 410 continue to move, thereby pushing the foot pad 300 and the support leg 200, thus pushing the support leg 200 outward, and the auxiliary spring-loaded component drives the support leg 200 to unfold.
