Abstract
The utility model discloses an extension pipe for a bearing type support. The extension pipe comprises an outer pipe and an inner pipe, wherein the inner pipe is inserted into a pipe cavity of the outer pipe. The extension pipe is characterized in that a first groove rail and a second groove rail are arranged on the upper side and the lower side of the pipe cavity of the outer pipe; a third groove rail and a fourth groove rail are arranged on the upper side and the lower side of the inner pipe; a first row of bearings are arranged between the first groove rail and the third groove rail; and a second row of bearings are arranged between the second groove rail and the fourth groove rail. According to the extension pipe, a pipe is embedded into another pipe, so that the noise is eliminated, the extension pipe is stable and retractable; a limit bearing with high torque can be borne, and more choices can be provided for designing the support-like products. With the adoption of the extension pipe, the attractiveness of the appearance can be realized, the cost is reduced, and the practicability effect is realized.
Description
Technical field
The utility model relates to a kind of support telescopic pipe.
Background technique
At present, on support hanger series products, normally use the multi-layer tubes simple superposition and reach adjustable purpose.Multi-layer tubes roughly divides 2 kinds on the existing market: steel pipe and pack alloy tubing.Although steel pipe is with low cost, problem is to be difficult to accomplish attractive in appearance, and the joint be difficult to process, and welding manner more affects appearance effect.Though the pack alloy structural member can be realized the requirement on attractive in appearance, processing technology is complicated, and energy consumption is high, and reprocessing is loaded down with trivial details, and cost is high.
Summary of the invention
The purpose of this utility model is to design a kind of bearing type support telescopic pipe.
Although to be solved in the utility model is that existing steel pipe is with low cost, be difficult to accomplish that attractive in appearance, joint is difficult to process, though and the pack alloy structural member can be realized the requirement on attractive in appearance, the processing technology complexity, energy consumption is high, reprocessing is loaded down with trivial details, the problem that cost is high.
The technical solution of the utility model is:
It comprises outer tube and inner tube, inner tube inserts in the tube chamber of outer tube, it is characterized in that described outer tube tube chamber upside and downside are provided with the first grooved tracks and the second grooved tracks, same on inner pipe side and downside are provided with the 3rd grooved tracks and the 4th grooved tracks, between the first grooved tracks and the 3rd grooved tracks, be equipped with the first row bearing, between the second grooved tracks and the 4th grooved tracks, be equipped with the second row bearing.
The utility model has the advantages that: it is by the nested pipe of pipe, and realizes that noise free is steadily flexible, and the limit load-bearing that can bear high pulling torque, for the design of support series products provides more selection.And the utility model reach take into account attractive in appearance, cost and practical effect.

Fig. 3 is the structural relation figure of the utility model bearing and inner tube.
Fig. 4 is the utility model end construction schematic diagram.
Among the figure: 1. outer tube, 2. bearing cap, 3. inner tube, 4. bearing baffle, 5. bearing.
Embodiment
Now reaching by reference to the accompanying drawings embodiment is further described the utility model.
As shown in the figure, the utility model comprises outer tube 1 and inner tube 3, inner tube 3 inserts in the tube chamber of outer tube 1, described outer tube 1 tube chamber upside and downside are provided with the first grooved tracks and the second grooved tracks, same is provided with the 3rd grooved tracks and the 4th grooved tracks at inner tube 3 upsides and downside, between the first grooved tracks and the 3rd grooved tracks, be equipped with the first row bearing, between the second grooved tracks and the 4th grooved tracks, be equipped with the second row bearing.
Two side chamber walls of described tube chamber are the indent arcuate structure, inner tube 3 two sidewalls also be the indent arcuate structure and with the indent arc structure matching of tube chamber two side chamber walls.
The end of outer tube 1 and inner tube 3 is respectively equipped with bearing cap 2 and bearing baffle 4, for the slip of bearing 5 and inner tube 3 spacing.
Claims (3)
1. bearing type support telescopic pipe, comprise outer tube and inner tube, inner tube inserts in the tube chamber of outer tube, it is characterized in that described outer tube tube chamber upside and downside are provided with the first grooved tracks and the second grooved tracks, same on inner pipe side and downside are provided with the 3rd grooved tracks and the 4th grooved tracks, between the first grooved tracks and the 3rd grooved tracks, be equipped with the first row bearing, between the second grooved tracks and the 4th grooved tracks, be equipped with the second row bearing.
