Description

Technical Field

[0001] The utility model relates to the technical field of camera tripods, and particularly relates to a tripod support leg structure. Background Art

[0002] Tripods are usually used to support photographic, videographic or surveying equipment. In order to prevent the tripod legs from slipping when providing support, rubber foot pads or spikes need to be installed at the lower ends of the legs according to different sites. When the site is a hard ground, rubber foot pads need to be installed at the lower ends of the tripod legs. When the site is soft ground such as snow or sand, spikes need to be installed at the lower ends of the tripod legs. This means that when the tripod is switched to different sites, the lower ends of the legs also need to be switched back and forth between the foot pads and the spikes. To solve this problem, the traditional solution is to remove the foot pads and then install the spikes, or remove the spikes and then install the foot pads. The operation is cumbersome, and the removed foot pads or spikes also need to be properly stored to avoid loss. Summary of the Utility Model

[0003] In view of the above deficiencies of the current tripod, the utility model provides a tripod support leg structure, which can quickly switch between two support modes of snow spikes and foot pads, and achieve stable support on soft ground.

[0004] To achieve the above object, the embodiments of the utility model adopt the following technical solutions:

[0005] A tripod support leg structure includes three leg tubes installed on a base. Snow spikes are installed at the bottoms of the leg tubes. The upper ends of the snow spikes are fixedly connected in the tube holes of the leg tubes, and the tips of the snow spikes protrude from the lower end faces of the leg tubes. A sheathing that can move up and down is also provided at the bottom of the leg tubes. The snow spikes are wrapped in the sheathing, and friction blocks are arranged between the snow spikes and the sheathing. By rotating the sheathing to drive the friction blocks to rotate, the friction blocks are clamped between the snow spikes and the sheathing.

[0006] In one embodiment, the friction blocks are in a semi-circular ring structure, and the thickness of the friction blocks gradually increases from left to right.

[0007] In one embodiment, the snow spike includes an interface section, a main body section and a penetrating section from top to bottom. The interface section is fixedly connected in the tube hole of the leg tube. The main body section is connected to the sheathing through the friction blocks. The interface section, the main body section and the penetrating section are integrally formed structures.

[0008] In one embodiment, the friction blocks are embedded and connected in the main body section, and the part of the main body section connected to the friction blocks is elliptical.

[0009] In one embodiment, a protrusion is provided on one side of the main body portion for rotationally limiting the friction block.

[0010] In one embodiment, a foot pad is fixedly connected to the bottom of the sheath. The foot pad includes a limiting end and a bottom end. The foot pad is designed in an L-shaped structure and is provided with a through hole for the snow peg to pass through.

[0011] In one embodiment, a plurality of anti-slip protrusions or patterns are provided on the foot pad.

[0012] In one embodiment, the surface of the friction block in contact with the sheath is designed as an uneven plane.

[0013] The beneficial effects of the present utility model lie in providing a tripod support foot structure, which is applicable to soft ground environments such as snow and sand. Through the tip design of the snow peg and the adjustment function of the sheath, it can quickly switch between two support modes of the snow peg and the foot pad, effectively providing stable support force; through the clamping action of the friction block and the anti-slip designs of the sheath and the foot pad, it has extremely high stability and reliability; the sheath is designed as a rotatable structure, and the tightness of the friction block can be adjusted according to needs to adapt to different terrains and usage requirements.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 and Figure 2 shown, a tripod support foot structure includes three pins 1 installed on a base. A snow insert 2 is installed at the bottom of each pin 1. The upper end of the snow insert 2 is fixedly connected in the pipe hole of the pin 1, and the tip of the snow insert 2 protrudes from the lower end surface of the pin 1. The pin 1 can be made of high-strength aluminum alloy or carbon fiber material to ensure sufficient load-bearing capacity and lightness. A pipe hole is machined inside the pin 1 for fixedly connecting the interface section 21 of the snow insert 2.

[0024] Specifically, the snow stake 2 includes an interface section 21, a main body section 22, and a penetrating section 23 from top to bottom. The interface section 21 is fixedly connected inside the tube hole of the pin 1. The main body section 22 is connected to the sheath 3 through a friction block 4. The penetrating section 23 is designed as a sharp conical or nail-like structure to penetrate the snow or soft ground. The interface section 21, the main body section 22, and the penetrating section 23 are integrally formed structures, which improves the strength and stability of the overall structure.

[0025] As Figure 3 and Figure 4 shown, a sheath 3 that can move up and down is provided at the bottom of the pin 1. The snow stake 2 is wrapped inside the sheath 3, and a friction block 4 is provided between the snow stake 2 and the sheath 3. The friction block 4 can be made of rubber or polymer composite material with good wear resistance, having sufficient elasticity and friction force, and can effectively clamp the snow stake 2 when the sheath 3 is rotated. By rotating the sheath 3, the sheath 3 drives the friction block 4 to rotate, so that the friction block 4 is clamped between the snow stake 2 and the sheath 3, thereby realizing the firm fixation of the snow stake 2. In this embodiment, the friction block 4 is a semi-circular ring structure, and its thickness gradually increases from left to right. This design enables the friction block 4 to fit more closely to the snow stake 2 when the sheath 3 is rotated, enhancing the friction force and improving the fixation effect.

[0026] The sheath 3 can be made of lightweight alloy or plastic material, and its surface is designed with anti-slip textures for easy hand holding and rotation.

[0027] The friction block 4 is embedded and connected in the main body section 22. The part of the main body section 22 connected to the friction block 4 is oval-shaped, and a protrusion 41 is provided on one side of the main body section 22 for limiting the rotation of the friction block. Such a design helps the friction block 4 to clamp the snow stake 2 more effectively when the sheath 3 is rotated, preventing it from loosening in the snow.

[0028] The surface of the friction block 4 in contact with the sheath 3 is designed as an uneven plane, which can be a fine uneven texture or a structure with alternating protrusions 41 and grooves to increase the complexity of the contact surface and the friction force.

[0029] In practical applications, a foot pad 5 is fixedly connected to the bottom of the sheath 3. The foot pad 5 can be made of high-elastic rubber or silicone material to further increase the stability of the tripod on snow or other soft ground. The foot pad 5 includes a limiting end 51 and a bottom end 52. The foot pad 5 is designed in an L-shaped structure, and the foot pad 5 is provided with a through hole 53 for the snow stake 2 to pass through.

[0030] Multiple anti-slip protrusions 41 or textures are also provided on the foot pad 5 to enhance the friction with the ground and prevent the tripod from sliding during use.

[0031] The present utility model provides a tripod support leg structure. The sheath 3 is designed to be a structure that can move up and down and rotate. It is sleeved outside the snow stake 2, and a friction block 4 is provided between the sheath 3 and the snow stake 2. The friction block 4 is a semi-circular ring structure, and its thickness gradually increases from one side to the other side. By rotating the sheath 3, the friction block 4 can be driven to rotate on the main body portion 22 of the snow stake 2 and drive the snow stake 2 to move up and down, so as to adjust the tightness between the friction block 4 and the snow stake 2 and achieve a stable fixing effect. At the same time, the part of the main body portion 22 connected to the friction block is elliptical, and such a design helps to enhance the locking force between the friction block 4 and the snow stake 2.

[0032] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the scope of the utility model patent.

[0033] In order to make it more convenient for those of ordinary skill in the art to understand the improvements of the present utility model over the prior art, some drawings and descriptions of the present utility model have been simplified. And for the sake of clarity, some other elements have also been omitted in this application document. Those of ordinary skill in the art should be aware that these omitted elements may also constitute the content of the present utility model.
