Description

New retractable protective tube

technical field

The utility model relates to the field of protective pipes, in particular to a novel retractable protective pipe.

Background technique

The main function of the steering column is the steering transmission function, that is, the force applied on the steering wheel is transmitted to the steering intermediate shaft, and then transmitted to the steering gear by the steering intermediate shaft, and then the steering gear applies it to the wheels to realize the steering of the car. Steering, and the protective tube assembly is an important part of the mechanism and connects all other steering accessories (such as switch brackets), so it is particularly important to study this product and improve this product, while the protective tube design of the prior art generally uses tubes Casing design (the upper and lower protective pipes are connected by telescopic bushings), in this design, the upper and lower protective pipes are connected by bushings, so the rigidity and natural frequency of the pipe string are affected.

Utility model content

The technical problem mainly solved by the utility model is to provide a novel telescopic protective tube.

In order to solve the above technical problems, a technical solution adopted by the utility model is to provide a new type of retractable protective tube, including: a lower protective tube, an upper protective tube, an adjustment handle and a steering wheel, and the side section of the lower protective tube It is Ω-shaped, one side of the lower protective tube is provided with an upper protective tube, and one end of the upper protective tube is inserted into the lower protective tube, and the unclosed opening of the lower protective tube is A connecting rod is provided, and one side of the connecting rod is connected with the adjusting handle.

In a preferred embodiment of the present invention, the adjustment handle is L-shaped.

In a preferred embodiment of the present utility model, a steering wheel is provided on one side of the upper protection tube.

The beneficial effects of the utility model are: the utility model is a new type of retractable protective tube, which reduces the sliding force between the upper and lower protective tubes, and the column has better rigidity than the existing design when the adjustment mechanism is locked. and natural frequency, and this design does not need a bushing, low cost, easy assembly between the upper and lower protection tubes, reduces assembly time, and improves productivity.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings that need to be used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some implementations of the present invention. For example, for those of ordinary skill in the art, other drawings can also be obtained based on these drawings without creative work, wherein:

Fig. 1 is a three-dimensional structural schematic diagram of a preferred embodiment of the new retractable protection tube of the present utility model.

The marks of each part are as follows in the accompanying drawings: 1, lower protective pipe, 2, upper protective pipe, 3, adjustment handle, 4, steering wheel.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to FIG. 1 . FIG. 1 is a three-dimensional structural schematic view of a preferred embodiment of the new telescopic protective tube of the present invention.

The utility model is a new type of retractable protective tube, comprising: a lower protective tube 1, an upper protective tube 2, an adjustment handle 3 and a steering wheel 4, the side section of the lower protective tube 1 is Ω-shaped, and the Ω-shaped section is connected. This design not only reduces the bushing between the upper and lower protective pipes, the cost of raw materials is low, the time for bushing assembly is omitted, and the productivity is improved. One side of the lower protective pipe 1 is provided with an upper protective pipe 2, and the upper protective pipe 2 is provided. One end of the protective tube 2 is inserted in the lower protective tube 1, and a connecting rod is arranged on the unclosed opening of the lower protective tube 1, and one side of the connecting rod is connected with the adjusting handle 3, and the The matching method of the lower protective tube 1 and the upper protective tube 2 is changed, and the lower protective tube 1 and the upper protective tube 2 pass through the Ω-shaped section, which does not require a telescopic bushing, increases the natural frequency, reduces costs, and reduces the assembly of the two time and increase productivity.

In a preferred embodiment of the present utility model, the adjustment handle 3 is L-shaped. When adjusting the tightness, the L-shaped use is more convenient. After the adjustment handle 3 is locked, the upper protective tube 2 and the lower protective tube The gap between 1 is small, thereby improving the stiffness and natural frequency of the pipe string.

In a preferred embodiment of the present utility model, a steering wheel 4 is provided on one side of the upper protective tube 1 , and the steering wheel 4 is connected with the bearing inside the upper protective tube 1 .

The new retractable protection tube of the utility model solves the defects in the technical solution. This protection tube reduces the sliding force between the upper and lower protection tubes, and the pipe column has better rigidity than the existing design when the adjustment mechanism is locked. And the natural frequency, and this design does not need a bushing, the cost is low, the assembly between the upper and lower protective tubes is easy, the assembly time is reduced, and the productivity is improved.

The above descriptions are only embodiments of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the description of the utility model and the contents of the accompanying drawings, or directly or indirectly used in other Related technical fields are all included in the patent protection scope of the present utility model in the same way.
