Description

Technical Field

[0001] This utility model belongs to the field of support technology, specifically relating to a telescopic tripod. Background Technology

[0002] In some applications, a support structure is required, such as for cameras and supplementary lighting. These structures often use tripods for easy placement and positioning, and also allow for height adjustment. Existing technology typically uses a tripod body, a telescopic rod, and a telescopic adjustment knob. For example, CN201620909572.6 describes a multi-functional test frame for a security technology prevention system. While this allows for locking, it primarily relies on the end face of a screw for locking. Prolonged use can damage the lifting rod and cause it to fall automatically. The locking stability is limited, and the aesthetics are poor, thus restricting its applicability. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] See Figures 1 to 6 As shown, a telescopic tripod includes a tripod support 1 and a lifting rod 2 mounted on the tripod support. The tripod support is a conventional structure in the prior art and is simply applied, so it is not described in detail. In practical applications, the lifting rod includes a hollow lifting main rod 21, a telescopic rod 22, an external threaded sleeve 23, an internal threaded locking sleeve 24, and a C-shaped fastener 25. The C-shaped fastener is a fastener made of a 1-2mm thick metal sheet wound or molded and 3-10cm high. Both the external threaded sleeve and the internal threaded locking sleeve are metal structural parts. The outer diameter of the external threaded sleeve matches the inner diameter of the hollow lifting main rod. Matching means that the outer diameter of the external threaded sleeve and the inner and outer diameters of the hollow lifting main rod are within the same tolerance range. The lower thread of the external threaded sleeve is screwed into the hollow lifting main rod for fixation.

[0018] During connection, the lower part of the hollow lifting main rod is connected to the tripod support; the lower part of the external threaded sleeve is connected to the top of the hollow lifting main rod; the internal threaded locking sleeve is located on the outside of the telescopic rod body; and the C-shaped fastener is located at the connection between the telescopic rod body and the external threaded sleeve. The lower part of the telescopic rod body is inserted into the hollow lifting main rod, and the internal threaded locking sleeve is threadedly connected to the external threaded sleeve. When tightened, the C-shaped fastener is compressed to clamp the telescopic rod body to the top of the hollow lifting main rod. In actual application, the lower end of the C-shaped fastener is inserted between the telescopic rod body and the external threaded sleeve, and the upper part of the C-shaped fastener abuts against the inner wall of the internal threaded locking sleeve. When the internal threaded locking sleeve is tightened and moves downward, it will compress and retract the C-shaped fastener, thereby clamping it against the outer wall of the telescopic rod body.

[0019] In this embodiment, the C-shaped fastener has a sidewall thickness that is thicker at the bottom and narrower at the top. When the internal threaded locking sleeve is tightened with the external threaded sleeve, the C-shaped fastener is squeezed against the inner wall of the internal threaded locking sleeve, causing the lower part to contract and press against the telescopic rod. Meanwhile, for ease of operation, the outer wall of the internal threaded locking sleeve is provided with several vertical anti-slip grooves 3.

[0020] In this embodiment, a through hole 4 is provided in the center of the top surface of the tripod support; a support plate 5 is provided between the bottom of the hollow lifting main rod and the tripod support; an end cap 8 is provided in the center of the support plate. During assembly, the hollow lifting main rod passes through the through hole, and the bottom end of the hollow lifting main rod is inserted into the end cap. The two ends of the support plate are respectively connected to the end cap and the middle of the legs of the tripod support by pins. When the tripod support is opened, the support plate will drive the end cap to rise, and at the same time, the hollow lifting main rod will rise. Furthermore, the side wall of the tripod support is provided with a positioning screw hole that communicates with the through hole, and the positioning screw hole is internally threaded with a wing screw 6; the hollow lifting main rod rises and falls within the through hole and is locked and positioned by the wing screw.

[0021] To facilitate the connection of electronic devices, a clamp body 7 for positioning the electronic devices is fixed to the top of the telescopic rod. The clamp body can hold supplementary lights, etc.

[0022] This utility model has positive effects: Its structure is reasonably designed, with the lifting rod comprising a hollow lifting main rod, a telescopic rod, an external threaded sleeve, an internal threaded locking sleeve, and a C-shaped fastener. The external threaded sleeve and internal threaded locking sleeve, in conjunction with the C-shaped fastener, compress the C-shaped fastener when the internal threaded locking sleeve is tightened, thus clamping the telescopic rod. This not only makes operation convenient, requiring only rotation and tightening, but also improves the overall aesthetics. Furthermore, the C-shaped fastener increases the clamping contact area of ​​the telescopic rod, ensuring the effectiveness and reliability of the lifting adjustment and locking, enhancing stability, and making it highly applicable.

[0023] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0024] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
