Description

Technical Field

[0001] The utility model relates to the technical field of telescopic rods, in particular to a telescopic support rod. Background Art

[0002] As a mechanical component with adjustable height, compact structure and powerful function, the telescopic support rod is widely used in many fields such as furniture, photographic equipment, medical equipment, industrial equipment and daily life. It adopts a precise sliding or telescopic mechanism, allowing users to easily adjust its length according to actual needs to achieve the best support effect.

[0003] For example, a telescopic support rod disclosed in the prior art (CN208899204U) realizes the telescoping of two pipe fittings mainly through threaded connection, and there are also some known in the art that use elastic detents to realize the telescoping function of two pipe fittings, etc.

[0004] However, whether it is threaded connection or elastic detent connection, generally only the telescoping adjustment of two pipe fittings is carried out, and the multi-stage telescoping adjustment and fixation of multiple pipe fittings sleeved layer by layer cannot be carried out, so the use environment is relatively limited; there are also some telescopic rods similar to the antenna structure, which can only be fixed and telescoped by using the friction force between the pipe fittings, and the practicability is relatively poor and cannot be used for support. Summary of the Invention

[0005] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide a telescopic support rod.

[0006] The technical solution adopted by the utility model to achieve its technical purpose is: a telescopic support rod, including a pipe, the pipe is a telescopic rod made by sleeving multiple pipe fittings layer by layer, and a locking mechanism is arranged at the telescopic end of the pipe;

[0007] The locking mechanism includes an external clamping ring and an internal clamping ring. The internal clamping ring is locked on the outer walls of every two adjacent layers of pipe fittings, and the external clamping ring is locked at one end of the internal clamping ring;

[0008] A locking switch handle is rotatably arranged on the outside of the external clamping ring. By adjusting the tightness of the external clamping ring through the locking switch handle, the tightness of one end of the internal clamping ring is adjusted, so that every two adjacent layers of pipe fittings are fixed or relatively moved.

[0009] Preferably, the internal clamping ring is locked and fixed on the pipe through screws and nuts, and the other end of the internal clamping ring is locked on the pipe fitting close to the tail of the pipe through screws and nuts.

[0010] Preferably, the external clamping ring is locked and fixed to one end of the internal clamping ring by a locking screw rod, and a spring sleeve is arranged on the outer wall of the locking screw rod at the connection opening of the external clamping ring; the external clamping ring is located at one end of the internal clamping ring, and at the same time, the external clamping ring and one end of the internal clamping ring are located on the pipe fitting away from the tail of the pipe, and a spring is arranged at the connection opening of the external clamping ring to provide reverse resistance, so that the opening and closing process is smoother.

[0011] Preferably, after one end of the locking screw rod passes through the external clamping ring, one end of the locking screw rod is threadedly connected to a rotating shaft, and the locking switch handle is rotatably connected to the rotating shaft; through the setting of the rotating shaft, the locking switch handle can be rotated around the rotating shaft, and when the locking switch handle is bent away from one end in the direction away from the external clamping ring, the other end of the locking switch handle can temporarily release the connection opening of the external clamping ring, so that the external clamping ring opens under the action of the spring, so that the external clamping ring can be loosened.

[0012] Preferably, the locking mechanism also includes a gasket, which is located between each two adjacent pipe fittings. The gasket is used to provide a fixed gap between adjacent inner tubes and outer tubes in the pipe, and is placed between the inner tube and the outer tube to ensure that the inner tube and the outer tube will not be scratched or stuck during use, thereby ensuring the integrity of the tube wall and the smoothness of the expansion and contraction during long-term use.

[0013] Preferably, a tail handle is fixedly provided at one end of the tube, which is used to provide anti-slip during operation. The notch at the tail can protect the pipeline passing through the tube from being folded. A head connector is fixedly provided at the other end. The function of the head connector is to adapt to the equipment connected to the head, and there are various types.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The telescopic support rod, through the setting of the locking mechanism and the pipe, can realize multi-level telescopic adjustment and fixation of multiple pipe fittings in the pipe, so that the overall adjustment performance is better, and at the same time it can meet the effect of fixed support. The telescopic adjustment is also diverse and can be easily adapted to various usage environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1-3 , a telescopic support rod, including a pipe 3, which is a telescopic rod made by sleeving multiple pipe fittings layer by layer. A locking mechanism is provided at the telescopic end of the pipe 3; one end of the pipe 3 is fixedly provided with a tail handle 1, and the tail handle 1 is used to provide anti-slip during operation. The notch at the tail can protect the pipeline passing through the pipe 3 from being folded. The other end is fixedly provided with a head connector 8, and the function of the head connector 8 is to adapt and connect the equipment at the head, and there are various types.

[0025] The locking mechanism includes an external clamp ring 6 and an internal clamp ring 7. The internal clamp ring 7 is locked to the outer wall of each adjacent two layers of the pipe. The internal clamp ring 7 is locked and fixed to the pipe 3 by screws 11 and nuts 12. The other end of the internal clamp ring 7 is locked to the pipe near the tail of the pipe 3 by screws 11 and nuts 12.

[0026] The outer clamp ring 6 is locked to one end of the inner clamp ring 7; the outer rotation of the outer clamp ring 6 is provided with a locking switch handle 2, and the tightness of the outer clamp ring 6 is adjusted by the locking switch handle 2, and then the tightness of one end of the inner clamp ring 7 is adjusted, so that the pipes of each adjacent two layers are fixed or relatively moved.

[0027] Furthermore, in the present embodiment, the outer clamp ring 6 is locked and fixed to one end of the inner clamp ring 7 by means of a locking screw rod 5, and a spring 10 is provided at the connection opening of the outer clamp ring 6 and is sleeved on the outer wall of the locking screw rod 5; the outer clamp ring 6 is located at one end of the inner clamp ring 7, and at the same time, the outer clamp ring 6 and one end of the inner clamp ring 7 are located on the pipe fitting away from the tail of the pipe 3, and a spring 10 is provided at the connection opening of the outer clamp ring 6 to provide reverse resistance, so that the opening and closing process is smoother.

[0028] After one end of the locking screw rod 5 passes through the external clamping ring 6, and one end thereof is threadedly connected with a rotating shaft 9, the locking switch handle 2 is rotatably connected to the rotating shaft 9; through the setting of the rotating shaft 9, the locking switch handle 2 can be rotated around the rotating shaft 9. When the locking switch handle 2 is bent away from one end in the direction away from the external clamping ring 6, the other end of the locking switch handle 2 can temporarily not press against the connecting opening of the external clamping ring 6, so that the external clamping ring 6 opens under the action of the spring 10, so that the external clamping ring 6 can be loosened.

[0029] Furthermore, in this embodiment, the locking mechanism also includes a gasket 4, which is located between each two adjacent pipe fittings. The gasket 4 is used to provide a fixed gap between the adjacent inner tubes and outer tubes in the pipe 3, and is placed between the inner tube and the outer tube to ensure that the inner tube and the outer tube will not be scratched or stuck during use, thereby ensuring the integrity of the tube wall and the smoothness of the expansion and contraction during long-term use.

[0030] Specifically, when in use, the rotating shaft 9 is provided with a nut hole, and a rotating mechanism is formed by connecting the locking screw rod 5 and the locking switch handle 2 of the component. The locking force of the telescopic rod when locked is provided by the direction of the knob, so that the clamping force is applied or released to the clamping ring 7 inside the component by the rotation of the locking switch handle 2;

[0031] The external clamping ring 6 is, on the one hand, the core component connecting the pipe 3 and the locking mechanism. There is a convex structure inside the component that can bite into the hole positions on the top wall of the outer appearance of the pipe 3. On the other hand, by opening and closing the external clamping ring 6, the opening and closing of the component structure (there is an opening in the upper half of the component) is caused, and a clamping force is applied to or released from the inner pipe to complete the opening and closing process of the telescopic rod.

[0032] By connecting with the rotating shaft 9 and passing through the external clamping ring 6, the closing degree of the entire locking mechanism is adjusted. If the locking force decays after long-term use, the locking force can be strengthened by adjusting here (tightening), and vice versa.

[0033] It should be noted that although the above-mentioned embodiments have been described in this article, the patent protection scope of the present utility model is not limited thereby. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this article, or equivalent structural, equivalent process, or equivalent function transformations made by using the content of the specification and drawings of the present utility model, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present utility model.
