TECHNICAL FIELD

[0001] The present application relates to the technical field of support stands, in particular to an automatic pop-up support stand. BACKGROUND

[0002] As a common device support tool, support stands are widely used in the fields of photography, video shooting, projection, etc. With the popularity of portable electronic devices, the demand for support stands is increasing.

[0003] At present, a support stand generally comprises a main rod and a plurality of support legs, one end of each support leg is hinged to the main rod, when not in use, all the support legs are turned to adhere to the main rod to achieve folding, facilitating the storage and carrying of the device; when the support stand needs to be erected on the ground, the free end of each support leg is turned to gradually move away from the main rod to be unfolded, and a stable support structure is formed by the unfolded support legs and the ground. However, when unfolding the support legs, the user needs to manually operate the support legs, specifically, the free end of each support leg needs to be turned one by one to gradually move away from the main rod, and the angle of each support leg needs to be carefully adjusted to ensure that the device can be stably placed, which is not only cumbersome but also time-consuming. SUMMARY In order to improve the efficiency of the support stand, the present application provides an automatic pop-up support stand.

[0004] The automatic pop-up support stand provided by the present application adopts the following technical solution: An automatic pop-up support stand comprises: a main rod, a sliding sleeve is slidably connected to the main rod, a support leg is hinged to the sliding sleeve, and the free end of the support leg away from the sliding sleeve is a free end; an unlocking assembly for locking the folding state of the support leg and unlocking the support leg in the folding locked state after triggering the unlocking assembly; a pop-up assembly for popping up the support leg in the unlocking state and driving the free end of the support leg to move away from the main rod to completely unfold the support leg; a positioning assembly for positioning the position of the sliding sleeve when the support leg is in the completely unfolded state.

[0005] By adopting the above technical solution, the unlocking assembly can be triggered to unlock the folding state of the support leg, and then the pop-up assembly can pop up the support leg in the unlocking state and drive the free end of the support leg to move away from the main rod to completely unfold the support leg. At the same time, the positioning assembly can position the position of the sliding sleeve when the support leg is in the completely unfolded state, realizing one-key triggering and full-automatic unfolding function, which is simple and efficient in operation, improves the efficiency of the support stand, and has high reliability and long service life due to the use of mechanical locking and unlocking mechanism. The unfolded support leg is stably positioned to ensure the firmness of the support structure.

[0006] Optionally, the ejecting assembly comprises a support rod and an ejecting member, one end of the support rod is hinged to the support leg, one end of the ejecting member is connected to the main rod, and the other end of the ejecting member is abutted against the support rod.

[0007] By adopting the above technical scheme, when the unlocking assembly is triggered to release the support leg from the folded locking state, the one end of the ejecting member connected to the main rod provides stable support, and the other end of the ejecting member abutted against the support rod. Since one end of the support rod is hinged to the support leg, the elastic force of the ejecting member is transmitted to the support leg through the support rod, driving the support leg to rotate around the hinge point, so that the free end of the support leg is away from the main rod to realize unfolding. The elastic force of the ejecting member is effectively converted into the power of the support leg unfolding, realizing automatic ejecting of the support leg, reducing the cumbersome operation of manually unfolding the support leg one by one in the traditional leg stand, and improving the efficiency of the leg stand unfolding.

[0008] Optionally, the support leg comprises a leg part, a limiting part and a fixing part, the leg part is hinged to the main rod, the limiting part is connected to the leg part, the fixing part is engaged with the limiting part, the limiting part is provided with a mounting groove, the fixing part is inserted into the mounting groove, the fixing part and the groove wall of the mounting groove form a first hinge groove, and the ejecting assembly is inserted into the first hinge groove.

[0009] By adopting the above technical scheme, the leg part and the limiting part of the support leg are connected in an engaged manner, and the limiting part is provided with a mounting groove for inserting the fixing part, facilitating disassembly of each part of the support leg. At the same time, the ejecting assembly is inserted into the first hinge groove formed by the fixing part and the groove wall of the mounting groove, which is convenient for separation of the ejecting assembly when disassembling the support leg, facilitating disassembly of each component of the leg stand as a whole, and facilitating maintenance and component replacement.

[0010] Optionally, the unlocking assembly comprises a sliding member, an unlocking member and a first elastic member, the sliding member is slidably connected to the main rod, the unlocking member is connected to the sliding member, the free end of the support leg is engaged with the unlocking member, and the first elastic member is arranged between the sliding member and the main rod.

[0011] By adopting the above technical scheme, when the unlocking is triggered, the sliding member is pushed, the sliding member drives the unlocking member to move, and then the free end of the support leg is disengaged from the engagement state with the unlocking member, realizing the transition of the support leg from the folded locking state to the released locking state. The cumbersome process of manually unlocking the support leg one by one is avoided, the problem of time-consuming and cumbersome operation of unfolding the traditional support leg one by one is solved, and the efficiency is improved.

[0012] Optionally, the main rod comprises a base, a connecting seat and a rod part, the base is detachably fixedly connected to the connecting seat, the base and the connecting seat form a second hinge groove, the ejecting assembly is located in the second hinge groove, and the rod part is fixedly connected to the connecting seat.

[0013] By adopting the above technical solution, when the pop-up assembly is damaged, the main rod can be removed separately to replace the damaged part without replacing the sliding sleeve as a whole, thereby reducing maintenance costs, reflecting the advantages of modular design, and facilitating replacement.

[0014] Optionally, the support rod is connected to a rotating rod, and the connecting seat is provided with a sliding groove. The groove wall of the sliding groove is slidingly connected to a folding piece. The folding piece is used to push the rotating rod to rotate so that the support leg is folded. A locking piece is provided at one end of the folding piece close to the rotating rod. The base is rotatably connected to a two-way rod. The folding piece and the locking piece are movably assembled at both ends of the two-way rod respectively. The two-way rod is used to make the folding piece and the locking piece move toward or in opposite directions. The locking piece is slidably connected to the base. When the support leg is fully unfolded, the locking piece moves away from the end of the folding piece to the end of the flexible piece away from the unlocking piece, so that the end of the locking piece away from the folding piece is partially exposed to the air.

[0015] By adopting the above technical solution, when unfolded, the locking member is exposed to the air, which makes it easy to push the locking member, thereby facilitating the folding operation of the supporting leg, saving time and effort.

[0016] Optionally, the main rod is provided with an anti-rotation groove, the anti-rotation groove is arc-shaped, and the sliding sleeve is inserted into the anti-rotation groove.

[0017] By adopting the above technical solution, the arc-shaped anti-rotation groove provided on the main rod can be used for the sliding sleeve to be inserted. During the deployment of the tripod, the sliding sleeve slides along the anti-rotation groove. The arc-shaped anti-rotation groove can effectively limit the rotation of the sliding sleeve, reducing the possibility of unnecessary rotation during the sliding process, making the movement of the sliding sleeve more stable and smooth, thereby ensuring that the supporting legs can be deployed according to the predetermined trajectory, and improving the stability and reliability of the deployment of the tripod.

[0018] Optionally, the sliding sleeve includes a first ring and a second ring, the first ring and the second ring are detachably connected, and the first ring and the second ring are assembled to form a third hinge groove, and the supporting foot is hinged to the sliding sleeve through the third hinge groove.

[0019] By adopting the above technical solution, the sliding sleeve is set as a first ring and a second ring that can be detachably connected. During assembly, the first ring and the second ring can be operated separately, which makes it convenient to install the supporting foot in the third hinge groove formed by the two, thereby realizing the hinge connection between the supporting foot and the sliding sleeve, making the production and assembly process of the tripod more convenient and improving production efficiency. At the same time, when the supporting foot or the sliding sleeve of the tripod is damaged, the first ring or the second ring can be removed separately to replace the damaged part without replacing the sliding sleeve as a whole, thereby reducing maintenance costs, reflecting the advantages of modular design, and facilitating the maintenance and component replacement of the tripod.

[0020] Optionally, a flexible member is connected to the unlocking assembly and the end side away from the main rod.

[0021] By adopting the above technical solution, during the use of the tripod, when the unlocking component is triggered to unlock the supporting leg, since the unlocking component is connected to the end side away from the main rod with a flexible member, the flexible member can act as a buffer, reducing the wear and noise caused by collision, thereby improving the stability and durability of the entire automatic pop-up tripod.

[0022] Optionally, the positioning assembly includes a positioning block, which is fixed to the main rod. When the supporting legs are in a fully extended state, the sliding sleeve abuts against the positioning block.

[0023] By adopting the above technical solution, when the unlocking component is triggered to release the support leg from the retracted and locked state, the pop-up component drives the free end of the support leg away from the main rod, and the support leg gradually unfolds. During this process, the sliding sleeve slides on the main rod. As the support leg is fully unfolded, the sliding sleeve will abut against the positioning block during movement, thereby positioning the sliding sleeve when the support leg is in the fully unfolded state, ensuring the stability of the position of the support leg after unfolding, reducing the possibility of the sliding sleeve moving at will, and thereby improving the firmness of the entire tripod support structure, effectively solving the problem of unstable positioning of the support leg after unfolding. Compared with the existing technology, there is no need for manual additional adjustment of the positioning, and the operation is simpler and more efficient.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. During operation, the unlocking assembly is triggered to unlock the folded support legs. The pop-up assembly then pops up the released support legs, driving the free ends of the support legs away from the main pole, allowing the support legs to fully unfold. At the same time, the positioning assembly positions the sliding sleeves when the support legs are fully unfolded, achieving a one-touch trigger for fully automatic deployment. This makes operation simple and efficient, improving the deployment efficiency of the tripod. The mechanical locking and unlocking mechanism is highly reliable and has a long service life. The support legs are stably positioned after unfolding, ensuring the firmness of the support structure. 2. When the unlocking assembly is triggered to release the support legs from their retracted locked state, the end of the pop-up member connected to the main rod provides stable support, while the end of the pop-up member away from the main rod abuts against the support rod. Since one end of the support rod is hinged to the support legs, the elastic force of the pop-up member is transmitted through the support rod to the support legs, driving the support legs to rotate about the hinge point, causing the free ends of the support legs to move away from the main rod and unfold. This effectively converts the elastic force of the pop-up member into the driving force for the support legs to unfold, achieving automatic deployment of the support legs. This reduces the tedious manual operation of deploying the support legs one by one on traditional tripods and improves the deployment efficiency of the tripod. 3. When unfolded, the locking piece is exposed to the air, making it easier to push the locking piece and then to fold the supporting legs, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
