Technical Field

[0001] This utility model relates to the field of shooting accessories, and in particular to a portable auxiliary shooting stand. Background Technology

[0002] Auxiliary shooting supports are essential tools in photography, videography, live streaming, and other scenarios. They are used to stabilize equipment, adjust shooting angles, or expand functionality. Tripods are a common auxiliary structure used to stabilize cameras and other shooting equipment.

[0003] Traditional shooting supports, such as tripods and monopods, are usually manually unfolded by adjusting multiple legs radially outward to form a support structure. After expansion, they often need to be tightened by twisting and locking, which is cumbersome, time-consuming, and inconvenient. In addition, there is a significant risk of loosening when folding and storing such shooting supports, and the structure is unstable during transportation. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a portable auxiliary shooting bracket that is simple to deploy, easy to use, and structurally stable during storage and transportation.

[0005] A portable auxiliary shooting stand according to an embodiment of the present utility model includes:

[0006] The main components include a sleeve, a telescopic rod, and a lifting slider. The upper and lower ends of the sleeve are respectively provided with a ring cover and a base. The telescopic rod is connected to the base. The lifting slider passes through the sleeve and is ring-shaped and sleeved on the telescopic rod. The bottom of the ring cover is provided with a second magnetic attraction component. The lifting slider is provided with a first magnetic attraction component for attracting the second magnetic attraction component. The base is provided with a slider positioning cavity for storing the lifting slider. The slider positioning cavity is connected with n clearance grooves around its perimeter. The clearance grooves extend to the side and bottom of the base, where n is an integer greater than 2. The lifting slider is provided with n rotating grooves that match the corresponding clearance grooves.

[0007] The support leg assembly is provided in n groups. The support leg assembly includes a main support leg, a rotating shaft and an elastic element. One end of the main support leg is located in the rotating groove and passes through the relief groove. The main support leg is rotatably connected to the lifting slider through the rotating shaft. The two ends of the elastic element are respectively connected to the main support leg and the lifting slider, so that the main support leg forms a tendency to rotate away from the slider positioning cavity.

[0008] In this embodiment, the support leg assembly also includes a branch leg. The main support leg has a receiving groove and a limiting groove on the side near the slider positioning cavity. The receiving groove is parallel to the main support leg, and the limiting groove is perpendicular to the main support leg. The two ends of the limiting groove pass through the opposite sides of the main support leg. The width of the limiting groove is equal to the width of the receiving groove. The depth of the limiting groove, the depth of the receiving groove, and the thickness of the branch leg are equal. The length of the branch leg is equal to the length of the receiving groove.

[0009] In this embodiment, the bottom of the storage slot is provided with a first positioning slot, the bottom of the limiting slot is provided with a second positioning slot, and the top of the branch foot is provided with a positioning block that matches the first positioning slot and the second positioning slot.

[0010] In this embodiment, the positioning block is an anti-slip rubber block.

[0011] In this embodiment, a reinforcing rib is provided on the side of the main support leg away from the slider positioning cavity.

[0012] In this embodiment, the wall of the clearance groove is covered with a buffer layer.

[0013] In this embodiment, an anti-slip sleeve is provided at the end of the main support leg away from the rotating groove.

[0014] In this embodiment, a guide post is provided inside the sleeve, and the lifting slider is provided with a guide groove that matches the guide post.

[0015] The embodiments of this utility model have at least the following beneficial effects:

[0016] The telescopic rod, in conjunction with the sleeve, creates a dual guiding effect for the annular lifting slider, effectively improving the alignment of the slider's lifting motion, providing excellent anti-deviation performance, and ensuring high precision in the unfolding and retraction of the support leg assembly. This effectively reduces wear and extends service life. The elastic element, in conjunction with the rotating shaft, creates an outward-rotating unfolding motion trend for the main support leg. When the top of the sleeve is held and swung, the lifting slider and support leg assembly slide down the sleeve under inertia until the lifting slider enters the slider positioning cavity to align the rotating groove with the clearance groove. At this point, the circumferential limit of the main support leg is released, and the main support leg, under the pre-tightening force of the elastic element, can rotate around the sleeve to form a support structure. The unfolding operation is convenient, the deployment efficiency is high, and it is easy to use. Two magnetic attachments, respectively fixed to the sleeve and the lifting slider, create a reliable magnetic adsorption positioning effect when the support leg assembly is fully retracted into the sleeve. This effectively counteracts vibrations or collisions during transportation, significantly improving the stability of the retracted state during transport, providing excellent anti-loosening performance, a stable storage structure, and convenient transport and carrying.

[0033] Auxiliary shooting supports are essential tools in photography, videography, and live streaming, used to stabilize equipment, adjust shooting angles, or expand functionality. Tripods are a common auxiliary structure used to stabilize cameras and other shooting equipment. Traditional shooting supports, such as tripods and monopods, typically involve manually unfolding multiple legs and adjusting them radially outwards to form a support structure. After unfolding, they often require twisting and locking adjustments, making operation cumbersome, time-consuming, and inconvenient. Furthermore, folding and storing these supports also requires tedious folding and locking operations, resulting in long folding and storage times, hindering quick folding and storage, and posing a significant risk of loosening. The structure is also unstable during transportation, and vibrations during transport can easily cause the legs to detach and extend, making transportation difficult.

[0034] The following is for reference only. Figure 1 To be continued Figure 8 This invention describes a portable auxiliary shooting bracket that is simple to deploy and operate, easy to use, structurally stable, and convenient to transport.

[0035] Reference Figures 1 to 8 A portable auxiliary shooting bracket according to an embodiment of the present invention includes:

[0036] The main component 100 includes a sleeve 110, a telescopic rod 120, and a lifting slider 130. The upper and lower ends of the sleeve 110 are respectively provided with an annular cover 140 and a base 150. The fixed part of the telescopic rod 120 is connected to the center of the base 150. The telescopic rod 120 is positioned by an interference fit or rubber ring between its inner and outer tubes. The fixed part of this telescopic rod 120 is located on the outermost sleeve. The telescopic part of the telescopic rod 120 passes through the through hole of the annular cover 140. The lifting slider 130 passes inside the sleeve 110 and moves between the annular cover 140 and the base 150. The lifting slider 130 is annular and fits around the fixed part of the telescopic rod 120. The telescopic rod 120, in conjunction with the sleeve 110, provides reliable positioning and guidance for the lifting movement of the lifting slider 130. The lifting slider 130 can achieve aligned and reliable lifting within the sleeve 110. The bottom of the annular cover 140... The unit is provided with a second magnetic suction member 141, and the lifting slider 130 is provided with a first magnetic suction member 131 for magnetically adsorbing the second magnetic suction member 141. When the second magnetic suction member 141 and the first magnetic suction member 131 are close to each other, they can form a magnetic attraction force. The second magnetic suction member 141 and the first magnetic suction member 131 can be set as a combination of magnet and magnetic metal. The base 150 is provided with a slider positioning cavity 151 for housing the lifting slider 130. The slider positioning cavity 151 is connected with n clearance grooves 152 around its perimeter. All clearance grooves 152 are evenly distributed along a circumferential trajectory with the center of the slider positioning cavity 151 as the center. The clearance grooves 152 penetrate to the side and bottom surface of the base 150. n is an integer greater than 2, that is, n is at least 3. The lifting slider 130 is provided with n rotating grooves 132 that match the corresponding clearance grooves 152 respectively. The rotating grooves 132 penetrate to the side and bottom surface of the lifting slider 130.

[0037] The support leg assembly 200 has n groups. Each support leg assembly 200 includes a main support leg 210, a rotating shaft 220, and an elastic element 230. One end of the main support leg 210, the rotating shaft 220, and the elastic element 230 are all located in the rotating groove 132. The main support leg 210 also passes through the relief groove 152. One end of the main support leg 210 is rotatably connected to the lifting slider 130 via the rotating shaft 220, so that the main support leg 210 can slide relative to the lifting slider 130 around the rotating shaft 220. The rotating shaft 220 is perpendicular to the extension direction of the sleeve 110. The two ends of the elastic element 230 are respectively connected to the main support leg 210 and the lifting slider 130, so that the main support leg 210 forms a tendency to rotate away from the center of the slider positioning cavity 151. The elastic element 230 can be a torsion spring. For easy installation, both the lifting slider 130 and the main support leg 210 are provided with a rotating insertion hole. After one end of the support leg 210 passes through the rotating groove 132, the torsion spring and each rotating insertion hole are aligned. Then, the rotating shaft 220 passes through each rotating insertion hole and the torsion spring. At this time, the two ends of the rotating shaft 220 are respectively connected to the opposite two groove walls of the rotating groove 132. One end of the main support leg 210 is rotatably connected to the middle of the rotating shaft 220. The torsion spring is sleeved on the outside of the rotating shaft 220, and the two ends of the torsion spring are respectively connected to the main support leg 210 and the lifting slider 130. The torsion spring is used to make the main support leg 210 form the following movement trend: the top of the main support leg 210 rotates around the rotating shaft 220, and the bottom of the main support leg 210 rotates to the side away from the center of the slider positioning cavity 151. This allows the main support leg 210 to rotate from the relief groove 152 to the periphery of the sleeve 110 when the lifting slider 130 reaches the slider positioning cavity 151, so that the main support leg and the sleeve 110 form a near-vertical positioning support effect.

[0038] When storing: Refer to Figure 1 As shown, the lifting slider 130 is located at the top inside the sleeve 110, the second magnetic suction member 141 contacts and attracts the first magnetic suction member 131, and each support leg assembly 200 surrounds the telescopic rod 120. The extension direction of the main support leg 210 is parallel to the extension direction of the sleeve 110, and the end of the main support leg 210 away from the rotating groove 132 is located in the support positioning groove.

[0039] When using: Refer to Figures 2 to 6As shown, by holding the top of the sleeve 110 and swinging it to generate inertial force, the lifting slider 130 and each support leg assembly 200 move away from the annular cover 140. The main support leg 210 moves outward through the relief groove 152 until the lifting slider 130 reaches the slider positioning cavity 151. At this time, the rotating groove 132 and the relief groove 152 are aligned and connected. Under the elastic force of the elastic element 230, the main support leg 210 rotates around the rotating shaft 220, and the end of the main support leg 210 away from the rotating shaft 220 rotates outward around the sleeve 110 so that the main support leg 210 tends to be perpendicular to the sleeve 110. The main support legs 210 cooperate to form a reliable support and positioning effect.

[0040] The telescopic rod 120, in conjunction with the sleeve 110, creates a dual guiding effect for the annular lifting slider 130, effectively improving the alignment of the lifting slider 130's lifting motion and providing good anti-deviation performance. The extension and retraction of the support leg assembly 200 exhibits high motion precision, effectively reducing wear and extending its service life. The elastic element 230, in conjunction with the rotating shaft 220, creates an outward-rotating extension tendency for the main support leg 210. When the top of the sleeve 110 is held and swung, the lifting slider 130 and the support leg assembly 200 slide down the sleeve 110 under inertia until the lifting slider 130 enters the slider positioning cavity 151, aligning the rotating groove 132 with the clearance groove 152. Since the rotating groove 132 penetrates the side and bottom of the lifting slider 130... The main support leg 210 is released from its circumferential limiting state under the pre-tightening force of the elastic element 230. Under the action of the pre-tightening force of the elastic element 230, the main support leg 210 can rotate around the sleeve 110 to form a support structure. The unfolding operation is convenient, the unfolding deployment efficiency is high, and it is easy to use. Through two magnetic suction parts that are respectively fixed to the sleeve 110 and the lifting slider 130, when the support leg assembly 200 is completely stored in the sleeve 110, the two magnetic suction parts can form a reliable magnetic adsorption positioning effect, thereby effectively resisting the vibration or collision generated during transportation. It can effectively improve the stability of the storage state during transportation, has good anti-loosening performance, stable storage structure, convenient transportation and carrying, and high portability and adaptability.

[0041] Understandably, for each support leg assembly 200, the support leg assembly 200 also includes a branch leg 240. The main support leg 210 has a receiving groove 211 and a limiting groove 212 on the side near the center of the slider positioning cavity 151. When the main support leg 210 is stored inside the sleeve 110, both the receiving groove 211 and the limiting groove 212 are located on the side of the main support leg 210 near the central axis of the sleeve 110. When the main support leg 210 passes through the relief groove 152 and reaches the circumference of the sleeve 110, both the receiving groove 211 and the limiting groove 212 are located at the bottom of the main support leg 210. The receiving groove 211 and the limiting groove 212... 2. The storage groove 211 is distributed at intervals along the extension direction of the main support leg 210. The extension direction of the storage groove 211 is parallel to the extension direction of the main support leg 210. The extension direction of the limiting groove 212 is perpendicular to the extension direction of the main support leg 210. The two ends of the limiting groove 212 pass through the opposite sides of the main support leg 210. The width of the limiting groove 212 is equal to the width of the storage groove 211. The depth of the limiting groove 212, the depth of the storage groove 211, and the thickness of the branch leg 240 are equal. The length of the branch leg 240 is equal to the length of the storage groove 211. The length of the branch leg 240 is greater than the depth of the limiting groove 212.

[0042] When stored or unfolded normally, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the branch foot 240 is hidden in the storage slot 211, making it easy to carry.

[0043] When applying to surfaces with irregular shapes or long, recessed grooves, refer to Figure 4 As shown, the branch leg 240 is removed from the storage slot 211 and inserted into the limiting slot 212. At this time, the branch leg 240 is perpendicular to the main support leg 210, which can form a multi-dimensional reliable support and positioning effect, effectively adapting to different placement surfaces, especially complex outdoor environments, thereby assisting in achieving stable and reliable shooting. The branch leg 240 can be pried out of the storage slot 211 from the gap between the two. In addition, a clearance groove can be provided at the edge of the storage slot 211 to facilitate removal.

[0044] Understandably, the bottom of the storage slot 211 is provided with a first positioning slot 213, the bottom of the limiting slot 212 is provided with a second positioning slot 214, and the top of the branch leg 240 is provided with a positioning block 241 that matches the first positioning slot 213 and the second positioning slot 214. The positioning block 241 can be inserted into the first positioning slot 213 or the second positioning slot 214. Especially when unfolded for use, when the branch leg 240 is inserted into the limiting slot 212 and the positioning block 241 is inserted into the second positioning slot 214, the relative position between the branch leg 240 and the main support leg 210 can be effectively restricted from all directions, thereby effectively improving the stability of the support structure.

[0045] Understandably, the positioning block 241 is an anti-slip rubber block, such as a silicone block or a rubber block. By increasing friction, the stability of the structural position when the positioning block 241 is installed in the first positioning groove 213 or the second positioning groove 214 can be effectively improved. The length and width of the positioning block 241 are slightly larger than the length and width of the first positioning groove 213, and the length and width of the positioning block 241 are also slightly larger than the length and width of the second positioning groove 214. The tolerance can be set to 0.1~0.2mm, which can effectively improve the positioning effect.

[0046] In addition to being configured as an anti-slip rubber block, the positioning block 241 can also be configured as a magnetic block, and the main support leg 210 can be configured as a magnetic metal support leg, which can be easily picked up and put into combination by magnetic adsorption. Preferably, the branch leg 240 can also be configured as a magnetic support leg, which can further improve the stability of the combination positioning.

[0047] It is understandable that the main support leg 210 is provided with a reinforcing rib 215 on the side away from the center of the slider positioning cavity 151. When the main support leg 210 is housed in the sleeve 110, the reinforcing rib 215 is located on the side of the main support leg 210 close to the central axis of the sleeve 110. When the main support leg 210 passes through the relief groove 152 and reaches the periphery of the sleeve 110, the reinforcing rib 215 is located at the bottom of the main support leg 210.

[0048] It should be noted that the reinforcing rib extends along the extension direction of the main support leg 210. The reinforcing rib 215 can effectively improve the mechanical strength of the main support leg 210. Especially when the storage groove 211 and the limiting groove 212 are set, the reinforcing rib 215 can strengthen the mechanical structure of the main support leg 210, thereby effectively improving the reliability of positioning when deployed.

[0049] Understandably, the groove wall of the clearance groove 152 is covered with a buffer layer 153. When unfolded for use, the buffer layer 153 reduces the pressure between the main support leg 210 and the base 150, effectively extending the service life of the main support leg 210 and reducing the risk of the main support leg 210 being bent. Specifically, the buffer layer 153 can be a silicone layer or a rubber layer.

[0050] It is understandable that the end of the main support leg 210 away from the rotating groove 132 is provided with an anti-slip sleeve 216. When unfolded for use, the anti-slip sleeve 216 can effectively increase the friction between the main support leg 210 and the surface on which it is placed, thereby improving the stability of the support and positioning.

[0051] It is understood that the sleeve 110 is provided with a guide post 111 fixedly connected to the inner wall of the sleeve 110, and the lifting slider 130 is provided with a guide groove 133 that matches the guide post 111. Through the guide post 111 and the guide groove 133, the deflection between the lifting slider 130 and the sleeve 110 can be effectively avoided, thereby effectively improving the alignment of the lifting action of the lifting slider 130.

[0052] Understandably, the circumferential surface of the sleeve 110 is provided with a hand grip anti-slip layer, which makes it easy for users to hold and reduces the chance of the sleeve 110 slipping out of the user's hand when it is thrown out and unfolded. The hand grip anti-slip layer can be a layer structure with a high coefficient of friction, such as a rubber layer or a silicone layer.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
