Description

Technical Field

[0001] This utility model relates to the field of photographic supports, specifically to a quick-connect structure for the legs of a photographic support. Background Technology

[0002] In the field of photographic equipment, the camera stand, as a key component supporting cameras, camcorders, and other equipment, directly affects the ease of use, stability, and lifespan of its leg connection structure. Currently, the most common camera stand leg connection methods on the market include threaded connections, snap-fit ​​connections, and pin connections.

[0003] Threaded connections achieve fixation through the internal and external threads at the ends of the legs. While this structure provides a certain level of connection strength, installation and disassembly require repeated rotation of the legs, making the process cumbersome. This significantly reduces work efficiency, especially in outdoor shooting scenarios where quick adjustments to the tripod height are needed. Clip-on connections rely on the engagement of elastic clips with corresponding slots. However, over time, the clips are prone to fatigue and weakening, leading to loosening and even the risk of the legs detaching, compromising equipment safety. Pin connections require manual insertion and removal of the pins, which is not only cumbersome but also prone to loss, potentially delaying shooting in emergency situations. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a quick-connect structure for the legs of a camera bracket. This structure ensures connection strength while enabling quick assembly and disassembly of the legs, thus solving the technical problem of balancing connection efficiency and stability in existing technologies.

[0005] The objective of this utility model is achieved through the following means:

[0006] A quick-connect structure for a camera bracket leg includes a connecting rod, a first damping ball joint mounted on the upper end of the connecting rod, a top plate mounted on the upper end of the first damping ball joint, a bottom tube mounted on the lower end of the connecting rod, a cone head fixedly mounted on the lower end of the connecting rod, and a fixed outer ring rotatably mounted on the lower end of the connecting rod via a damping bearing. Side cavities are formed on both sides of the inner surface of the fixed outer ring. A return spring and a plug are sequentially installed from the inside out inside each side cavity, with the plug slidably connected to the side cavity. A bottom bevel is formed on one side of the lower end of the plug, and a side bevel is formed on one side of the outer surface of the plug. Square grooves are formed on both the left and right sides of the outer surface of the bottom tube near the plug.

[0007] Furthermore, the inclined surface is provided on the end face of the insertion block in the clockwise rotation direction, and a second damping ball joint is installed on the lower end face of the bottom tube, with a supporting chassis installed at the lower end of the second damping ball joint.

[0008] Furthermore, an anti-slip protrusion is installed at the lower end of the supporting chassis, and the anti-slip protrusion is fixedly connected to the supporting chassis. An anti-slip protrusion is provided along the outer edge of the fixed outer ring, which improves the anti-slip capability of the outer edge of the fixed outer ring.

[0009] Furthermore, a waterproof rubber ring is embedded on one side of the upper inner end of the bottom tube, and the waterproof rubber ring is fixedly connected to the bottom tube to prevent water from entering the bottom tube.

[0010] Furthermore, the cone head is provided with limiting plates on both the left and right sides of its exterior, and the bottom tube is provided with slots on both the left and right sides of its interior lower end. The limiting plates are adapted to the slots, and the combination of the slots and the limiting plates prevents the connecting rod from twisting with the bottom tube.

[0011] Furthermore, the connecting rod has a spiral guide groove on its outside, and the spiral guide groove is integrally formed with the connecting rod, which enhances the air convection heat dissipation effect.

[0012] The beneficial effects of this utility model are:

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figures 1-5 The specific implementation of the quick connection structure of the camera bracket legs includes a connecting rod 1, a first damping ball joint 3 installed at the upper end of the connecting rod 1, a top plate 4 installed at the upper end of the first damping ball joint 3, a bottom tube 5 installed on the lower end of the connecting rod 1, a cone head 12 fixedly installed at the lower end of the connecting rod 1, and a fixed outer ring 10 rotatably installed on the lower end of the connecting rod 1 through a damping bearing 9. The fixed outer ring 10 has side cavities 14 on both sides inside, and a return spring 15 and a plug 16 are installed in sequence from the inside to the outside of the side cavity 14. The plug 16 is slidably connected to the side cavity 14. A bottom inclined surface 17 is opened on one side of the lower end of the plug 16, and a side inclined surface 18 is opened on one side of the outer side of the plug 16. Square grooves 21 are opened on the left and right sides of the outer side of the bottom tube 5 near the plug 16.

[0021] like Figure 2 , Figure 4 and Figure 5 As shown, the side inclined surface 18 is provided on the end face of the insertion block 16 in the clockwise rotation direction. The lower end face of the bottom tube 5 is equipped with a second damping ball joint 6, and the lower end of the second damping ball joint 6 is equipped with a support base 7. When the fixed outer ring 10 rotates clockwise, the side inclined surface 18 collides with the side wall of the square groove 21. Under the action of the inclined surface, the insertion block 16 is retracted toward the side cavity 14, thereby canceling the connection between the bottom tube 5 and the connecting rod 1.

[0022] like Figure 3 and Figure 4 As shown, an anti-slip protrusion 8 is installed at the lower end of the support chassis 7, and the anti-slip protrusion 8 is fixedly connected to the support chassis 7. An anti-slip protrusion 11 is provided along the outer edge of the fixed outer ring 10. The anti-slip protrusion 11 improves the anti-slip ability of the outer edge of the fixed outer ring 10, and the anti-slip protrusion 8 improves the anti-slip ability of the bottom of the support chassis 7.

[0023] like Figure 2 and Figure 3 As shown, a waterproof rubber ring 13 is embedded on one side of the upper end of the bottom pipe 5, and the waterproof rubber ring 13 is fixedly connected to the bottom pipe 5. The waterproof rubber ring 13 prevents water from entering the interior of the bottom pipe 5.

[0024] like Figure 2 and Figure 3 As shown, the cone head 12 is provided with limiting plates 19 on both the left and right sides of the outside, and the bottom tube 5 is provided with slots 20 on both the left and right sides of the lower end inside. The limiting plates 19 and slots 20 are matched. The combination of slots 20 and limiting plates 19 prevents the connecting rod 1 and the bottom tube 5 from twisting.

[0025] like Figure 1 and Figure 2 As shown, a spiral guide groove 2 is provided on the outside of the connecting rod 1, and the spiral guide groove 2 is integrally formed with the connecting rod 1. The spiral guide groove 2 enhances the air convection heat dissipation effect.

[0026] The working principle of the quick connection structure of the camera bracket leg tube in this embodiment is as follows: When the connecting rod 1 is connected to the base tube 5, the cone head 12 is inserted into the base tube 5, and the limiting plate 19 is embedded in the slot 20 to prevent the two from twisting; the insert block 16 pops out of the side cavity 14 under the action of the return spring 15 and is inserted into the square groove 21 of the base tube 5 to fix the two; the anti-slip protrusion 11 on the outside of the fixing outer ring 10 is easy to hold, and when it rotates clockwise, the side inclined surface 18 of the insert block 16 collides with the side wall of the square groove 21. Under the action of the inclined surface, the insert block 16 is retracted into the side cavity 14, and the connection between the base tube 5 and the connecting rod 1 is released;

[0027] The spiral guide groove 2 on the outside of the connecting rod 1 enhances heat dissipation, and the waterproof rubber ring 13 prevents water from entering the bottom pipe 5. The supporting chassis 7 is connected to the bottom pipe 5 through the second damping ball joint 6, and the anti-slip convex ring 8 at its lower end enhances anti-slip performance. The top plate 4 is installed on the upper end of the connecting rod 1 through the first damping ball joint 3. The supporting chassis 7 can be adjusted to multiple angles through the second damping ball joint 6. The anti-slip convex strip 11 and the anti-slip convex ring 8 respectively enhance the anti-slip ability of the fixed outer ring 10 and the supporting chassis 7, ensuring the stability of the overall structure.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
