Background Technology
[0002] Existing foldable photography stands typically achieve portability through the extension or folding of multiple sections, but they suffer from the following problems: Limited carrying methods: users must hold the stand by hand or put it in a backpack, lacking quick-attachment features (such as carabiners), making operation in mobile shooting scenarios inconvenient; Limited functionality when folded: in the folded state, the end structure of the stand may be obstructed by other components, rendering the attachment holes unusable. To address these issues, this invention proposes a foldable photography stand with a carabiner, resolving the technical contradiction between portability, multi-functional adaptability, and complete functionality when folded by optimizing the folding structure and functional integration. Utility Model Content
[0003] The present invention provides a foldable photography bracket with a carabiner. The design of the carabiner at the end enables the quick attachment of the foldable photography bracket and ensures normal use of the carabiner when folded.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model provides a foldable photography bracket with a carabiner. The foldable photography bracket includes a main bracket, a secondary bracket, and an adapter. The two ends of the secondary bracket are rotatably connected to the main bracket and the adapter via pivots. A carabiner is provided at the end of the main bracket facing away from the secondary bracket. The carabiner includes a hanging hole formed at the end of the main bracket, a notch connecting the hanging hole to the outside, and a lever connected to the side wall of the notch via a torsion spring. When not bent, the lever closes the notch by the elastic force of the torsion spring. When bent, the lever rotates toward the inside of the hanging hole. In the folded state, the secondary bracket and the adapter are stacked sequentially on one side of the main bracket along the thickness direction of the main bracket. The lever is not blocked by the secondary bracket and the adapter on the rotation path of the lever. There is a gap between the end of the secondary bracket and the adapter connected to the end of the hanging hole facing away from the secondary bracket, and the gap allows the carabiner to be used normally.
[0006] In one embodiment, the outer side wall of the sub-support is provided with a cold shoe interface, and at least a portion of the structure of the cold shoe interface in the folded state is embedded in the central circular hole of the adapter, the diameter of the central circular hole being larger than the lateral dimension of the cold shoe interface.

The portion where the first plate and the second plate are connected is hinged to the side wall of the installation notch via a second pivot. The two support legs are respectively hinged to the second plate via a third pivot. When the support legs are unfolded, they form a tripod support structure with the main support. When folded, they are stacked between the main support and the sub-support. The support legs and the lever are offset in the thickness direction of the main support. The first pivot is parallel to the second pivot and perpendicular to the third pivot. In the folded state, the second plate is located within the installation notch, and the third pivot is parallel to the thickness direction of the main support.
[0009] In one embodiment, the hanging hole extends axially along the main bracket to both ends of the main bracket, the hanging hole forms the mounting notch at the front end of the main bracket, and at least a portion of the two legs in the folded state is embedded in the hanging hole.
[0010] In one embodiment, the main support is provided with a crossbeam located in the hanging hole. The crossbeam has a threaded hole along the thickness direction of the main support. The two legs are respectively provided with a first clearance notch and a second clearance notch corresponding to the threaded hole. In the folded state, the first clearance notch and the second clearance notch are connected to form a clearance circular hole. In the folded state, the threaded hole and the clearance circular hole are arranged opposite to each other and exposed through the clearance circular hole.
[0011] In one embodiment, both the end of the outrigger and the end of the main support are provided with an anti-slip structure. The anti-slip structure includes two grooves and an anti-slip rubber sleeve formed on the outrigger or the main support. The two grooves are arranged opposite to each other. One end of the anti-slip rubber sleeve is open and the other end is closed. Two sidewalls opposite to the open end of the anti-slip rubber sleeve are provided with integral buckles. The distance between the inner sides of the two buckles gradually decreases towards the inside of the opening. When the anti-slip rubber sleeve is fitted onto the end of the main support or the end of the outrigger, the main support or the outrigger moves along the inner side of the buckle, and the opening is expanded until the buckle is embedded in the groove.
[0012] In one embodiment, the sidewall of the notch is provided with an extension beam, the lever is provided with a stud, and the foldable camera bracket further includes a threaded connector. The threaded connector passes through the extension beam along the thickness direction of the main bracket and is threadedly connected to the stud. The torsion spring is sleeved on the stud and its two ends are respectively connected to the extension beam and the lever.
[0013] In one embodiment, the connecting end of the lever is provided with a receiving groove, and the side of the extension beam facing the connecting end of the lever is provided with a receiving groove of the same structure. The receiving groove includes a circular groove and a wire groove that are interconnected. The circular groove surrounds the stud. The circular grooves of the two receiving grooves are aligned with each other, and the wire grooves of the two receiving grooves are staggered. The torsion spring includes an axially extending winding section and extension sections located at both ends of the winding section. The extension sections at both ends of the winding section extend radially outward along the winding section. The winding section is simultaneously received in the two circular grooves, and the two extension sections are respectively received in the two wire grooves.
[0014] In one embodiment, the adapter is a magnetic adapter ring; or the adapter is a mobile phone clip with a telescopic function.
[0015] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:
[0016] This embodiment of the photographic bracket includes a main bracket, a secondary bracket, and an adapter. The two ends of the secondary bracket are connected to the main bracket and the adapter via pivots. A carabiner is located at the end of the main bracket, including a hanging hole, a notch, and a lever with a torsion spring. When folded, the secondary bracket and the adapter are stacked along the thickness direction of the main bracket, with a gap between their connecting ends and the end of the hanging hole, ensuring unobstructed rotation of the lever and normal use of the carabiner. The stacking design achieves compact storage while ensuring the carabiner remains functional even when folded. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0035] Please see Figures 1 to 4 This utility model provides a foldable photography bracket 10, including a main bracket 1, a secondary bracket 2, and an adapter 3. The two ends of the secondary bracket 2 are rotatably connected to the main bracket 1 and the adapter 3 respectively via pivots, so that the foldable photography bracket 10 can be used for... Figure 1 and Figure 2 The unfolded state shown is the same as Figure 3 and Figure 4Switch between the shown folded states. (Reference) Figure 1 and Figure 2 In its unfolded state, the foldable camera stand 10 forms a basically longitudinally extending rod-like structure. The foldable camera stand 10 can be used as a handheld selfie stick, allowing users to take selfies using a mobile phone mounted on the adapter 3. (Reference) Figure 3 and Figure 4 In the folded state, the sub-support 2 and the adapter 3 are stacked sequentially along the thickness direction of the main support 1. The camera support 10 in the folded state is small in size and easy to store when not in use.
[0036] refer to Figure 1 and Figure 5 A carabiner 4 is provided at the axial end of the main support 1 facing away from the secondary support 2. The carabiner 4 includes a hanging hole 41 formed at the end of the main support 1, a notch 42 connecting the hanging hole 41 to the outside, and a lever 43 connected to the side wall of the notch 42 by a torsion spring 44. When not bent, the lever 43 closes the notch 42 by the elastic force of the torsion spring 44. When bent, the lever 43 rotates toward the inside of the hanging hole 41. That is, under normal conditions, the lever 43 closes the notch 42 by the elastic force of the torsion spring 44; when bent, the lever 43 rotates toward the inside of the hanging hole 41, opening the notch 42 so that a rope, strap, or hook can enter. Therefore, when the user needs to use the function of the carabiner 4, he only needs to bend the lever 43 inward to open the notch 42, and then he can thread a rope, strap, or hook through the hanging hole 41. In one specific embodiment, to facilitate the installation of the lever 43, an extension beam 421 can be provided on the side wall of the notch 42. The extension beam 421 and the side wall of the notch 42 form a step, and the connecting end of the lever 43 overlaps on the step and is fixedly connected to the extension beam 421 via a pivot. Here, the lever 43 is provided with a stud 431, and the foldable camera bracket 10 also includes a threaded connector 5 (i.e., a pivot). The threaded connector 5 passes through the extension beam 421 along the thickness direction of the main bracket 1 and is threadedly connected to the stud 431. A torsion spring 44 is sleeved on the stud 431, and its two ends are fixedly connected to the extension beam 421 and the lever 43, respectively. When the lever 43 is bent toward the inside of the hanging hole 41, the lever 43 and the threaded connector 5 rotate synchronously around the axis of the threaded connector 5. During assembly, the damping of the lever 43 rotation can be adjusted by controlling the degree of contact between the screwing end of the threaded connector 5 and the extension beam 421 after the threaded connector 5 passes through the extension beam 421. If necessary, a washer can be placed between the screwing end of the threaded connector 5 and the extension beam 421 to avoid excessive friction and wear.
[0037] Continue to refer to Figure 5The connecting end of the lever 43 is provided with a receiving groove 432, and the side of the extension beam 421 facing the connecting end of the lever 43 is provided with a receiving groove 432 of the same structure. The receiving groove 432 includes a circular groove 4321 and a wire groove 4322 that are interconnected. The circular groove 4321 surrounds the stud 431. When the connecting end of the lever 43 overlaps on the step, the circular grooves 432 of the two receiving grooves 432 are aligned with each other, and the wire grooves 4322 of the two receiving grooves 432 are misaligned with each other. The torsion spring 44 includes an axially extending winding section 441 and extension sections 442 located at both ends of the winding section 441. The extension sections 442 at both ends of the axial direction extend outward along the radial direction of the winding section 441. When the torsion spring 44 is installed, the winding section 441 of the torsion spring 44 is simultaneously received in the two circular grooves 4321, and the two extension sections 442 of the torsion spring 44 are respectively received in the two wire grooves 4322.
[0038] In the folded state, the lever 43 is not obstructed by the sub-support 2 and the adapter 3 along its rotation path. There is a gap between the ends of the sub-support 2 and the adapter 3 and the end of the hanging hole 41 facing away from the sub-support 2. This gap allows space for ropes, hooks, or straps to pass through. Provided the lever 43 is not obstructed along its rotation path, this gap allows the carabiner 4 to be used normally. In one embodiment, the gap between the connecting ends of the sub-support 2 and the adapter 3 and the end of the hanging hole 41 is at least 5mm to ensure that the folded carabiner 4 can still be used normally with a strap or a hook of a standard size. The above example of the gap is merely an illustration; other sizes are also possible.
[0039] In one embodiment, reference Figure 3 and Figure 4 The outer wall of the secondary bracket 2 is equipped with a cold shoe interface 21 for mounting external devices such as fill lights and microphones. (Refer to the folded state) Figure 3 and Figure 4 At least a portion of the structure of the cold shoe interface 21 is embedded in the central circular hole 31 of the adapter 3. The diameter of the central circular hole 31 is larger than the lateral dimension of the cold shoe interface 21 to avoid interference between the cold shoe interface 21 and the adapter 3.
[0040] In one embodiment, reference Figure 2 and Figure 6 A magnet 11 is embedded on the side of the main bracket 1 facing away from the secondary bracket 2, and a sealing gasket 12 covers the outside of the magnet 11. Specifically, the main bracket 1 has a mounting groove 101 on the side facing away from the secondary bracket 2, and the magnet is placed in the mounting groove 101. The sealing gasket 12 is made of wear-resistant rubber and its height is slightly higher than the surface of the main bracket 1, which protects the magnet 11 from wear and ensures that the magnetic attraction force acts on the metal surface (such as railings, vehicle shells). Figure 2 and Figure 6The illustration shows four magnets 11 and four encapsulation pads 12, arranged in an array to enhance magnetic attraction. It should be understood that in other embodiments, the number of magnets 11 and encapsulation pads 12 is not limited.
[0041] It should be noted that in various embodiments of this utility model, the adapter 3 can be a magnetic adapter ring with a central circular hole 31, or the adapter 3 can be a telescopic phone clip. When the adapter 3 is a magnetic adapter ring, the axis of its central circular hole 31 coincides with the axis of the cold shoe interface 21, and when folded, the cold shoe interface 21 is partially embedded in the circular hole 31; when the adapter 3 is a telescopic phone clip, its clip arm can extend and retract to adapt to different phone sizes, and after folding, the clip arm is folded to the side of the main bracket 1. Of course, in other embodiments, the adapter 3 can also be a cold shoe mount, a gimbal, a dovetail plate, or other structures. In addition, the end of the main bracket 1 can also be provided with a lanyard hole 13 spaced apart from the hanging hole 41. By threading a cord through the lanyard hole 13, the photography bracket 10 can be tied to a backpack with a lanyard.
[0042] In one embodiment, reference Figures 7 to 9 The camera bracket 10 also includes an L-shaped fixing base 6 and two support legs 7. The main bracket 1 has a mounting notch 14 at its end. The L-shaped fixing base 6 includes a first plate 61 and a second plate 62 connected vertically. The end of the first plate 61 is rotatably connected to the auxiliary bracket 2 via a first pivot 81. The portion connecting the first plate 61 and the second plate 62 is hinged to the side wall of the mounting notch 14 via the second pivot 82. The two support legs 7 are respectively hinged to the second plate 62 via a third pivot 83. When the two support legs 7 are extended, they form a tripod support structure with the main bracket 1 (see reference). Figure 7 When folded, the two support legs 7 are stacked side by side between the main support 1 and the auxiliary support 2 (see reference). Figure 10 and Figure 11 Furthermore, the support leg 7 and the lever 43 are offset in the thickness direction of the main support 1. The first pivot 81 is parallel to the second pivot 82 and perpendicular to the third pivot 83. When the second plate 62 is folded, it retracts into the installation notch 14. At this time, the third pivot 83 is parallel to the thickness direction of the main support 1, which improves the structural compactness.
[0043] refer to Figure 9Two protruding pillars 621 can be provided on the second plate 62, and an arc-shaped track (not shown in the figure) can be provided on each of the two support legs 7. The two protruding pillars 621 are respectively embedded in the two arc-shaped tracks. When the two protruding pillars 621 move on the two arc-shaped tracks to one end of the two arc-shaped tracks that are close to each other, the two protruding pillars 621 abut against the sidewalls of the two arc-shaped tracks that are close to each other. At this time, the two support legs 7 are exactly in a side-by-side storage state. When the two protruding pillars 621 move on the two arc-shaped tracks to one end of the two arc-shaped tracks that are far apart from each other, the two protruding pillars 621 abut against the sidewalls of the two arc-shaped tracks that are far apart from each other. At this time, the two support legs 7 are exactly extended to their maximum angle. The maximum angle that the two support legs 7 can extend depends on the included angle between the far apart ends of the two arc-shaped tracks. This embodiment, through the cooperative design of the protruding pillars 621 and the arc-shaped tracks, can avoid damage to the support legs 7 due to excessive rotation.
[0044] In one embodiment, the hanging hole 41 extends axially along the main support 1 to both ends of the main support 1. The hanging hole 41 forms an installation notch 14 at the front end of the main support 1. At least a portion of the two legs 7 in the folded state are embedded in the hanging hole 41. In this way, the hanging hole 41 further reduces the size of the folded camera bracket 10, making it more convenient for users to store. Based on this, in order to optimize the external interface and function of the camera bracket, in one embodiment, the camera bracket 10 has a crossbeam 9 located in the hanging hole 41 in the main support 1. The crossbeam 9 has a threaded hole 91 along the thickness direction of the main support 1. The two legs 7 are respectively provided with a first clearance notch 71 and a second clearance notch 72 corresponding to the threaded hole 91. In the folded state, the first clearance notch 71 and the second clearance notch 72 are connected to form a clearance circular hole 73. In the folded state, the threaded hole 91 and the clearance circular hole 73 are opposite to each other and are exposed through the clearance circular hole 73. In this way, the external connection function of the threaded hole 91 is not affected whether in the folded state or the unfolded state.
[0045] In one embodiment, reference Figure 12 Both the end of the outrigger 7 and the end of the main support 1 are equipped with anti-slip structures 92. Figure 12Taking the example of the anti-slip structure 92 located at the end of the support leg 7, it should be understood that the anti-slip structure 92 at the end of the main support 1 is the same. The anti-slip structure 92 includes two locking grooves 921 formed in the support leg 7 or the main support 1 and an anti-slip sleeve 922. The two locking grooves 921 are arranged opposite each other. One end of the anti-slip sleeve 922 is open, and the other end is closed. Two sidewalls opposite the open end of the anti-slip sleeve 922 are provided with integral locking blocks 923. The distance between the inner surfaces of the two locking blocks 923 gradually decreases towards the inside of the opening. When the anti-slip sleeve 922 is fitted onto the end of the main support 1 or the end of the support leg 7, the main support 1 or the support leg 7 moves along the inner surface of the locking blocks 923 towards the inside of the opening, widening the opening until the locking blocks 923 are embedded in the locking grooves 921. Because the inner side of the opening end is provided with locking blocks 923 with a gradually decreasing spacing, during installation, the anti-slip sleeve 922 is fitted onto the end of the support leg 7, and the locking blocks 923 are deformed by compression and then snap into the locking grooves 921, achieving rapid fixation. This design prevents the rubber sleeve from falling off and facilitates replacement. It also improves the stability of the tripod support structure on the ground.
[0046] In summary, the workflow and beneficial effects of this utility model are as follows: In the unfolded state, the main support 1, the secondary support 2, and the adapter 3 extend longitudinally to form a handheld selfie stick. Users can mount their mobile phones via the adapter 3, connect peripherals via the cold shoe interface 21, or use the magnet 11 to attach them to a metal surface for fixation. In the folded state, the legs 7, the secondary support 2, and the adapter 3 are stacked compactly along the thickness direction of the main support 1; functional modules such as the carabiner 4, threaded hole 14, and magnet 11 are all exposed and usable, meeting the needs of quick attachment during mobile shooting. The core advantage of this utility model lies in achieving "zero interference" storage of functional modules through a stacked folding design; the modular structure (cold shoe interface, magnet, tripod support) expands the adaptability to outdoor shooting scenarios; and detailed designs such as anti-slip rubber sleeves and reinforced levers improve durability and operational efficiency.
