Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air volleyball column, specifically to an air volleyball column. BACKGROUND

[0002] The air volleyball column is a device used for supporting the net in the air volleyball game.

[0003] Based on the above, the present inventors found that: at present, there are many air volleyball columns on the market, but the connecting column between the general air volleyball column and the net is directly exposed and placed, which can easily erode the outer wall of the column and affect the normal use of the column after long-term use. The staff directly fixes and installs the shell of the column and the bearing block, so that the device needs to be used under different bearing requirements, and the staff needs to replace air volleyball columns of different weights for use, which can easily increase the cost burden of the work site and reduce the practicability of the device. Therefore, in view of the above, the existing structure is improved, and an air volleyball column is provided to achieve the purpose of higher practical value. SUMMARY

[0004] In order to solve the above technical problems, the utility model provides the following technical scheme:

[0005] The utility model relates to an air volleyball column, which comprises a column, the inner wall of the column is provided with a telescopic rod, the inner wall of the telescopic rod is matched with a connecting column, one side of the connecting column is fixed with a hemispherical column, the outer wall of the hemispherical column is provided with two wheel bodies, and the inner wall of the hemispherical column is provided with a bearing installation mechanism.

[0006] The bearing installation mechanism comprises:

[0007] The bottom end of the pull plate is slidably connected to the inner wall of the hemispherical column, and the top end of the pull plate is provided with a plurality of square bearing blocks.

[0008] As a preferred technical scheme of the utility model, the outer wall of the column is matched with a protective sleeve, and the protective sleeve is arranged on the outer wall of the connecting column.

[0009] As a preferred technical scheme of the utility model, the two sides of the hemispherical column are both provided with arc-shaped cover plates.

[0010] As a preferred technical scheme of the utility model, the two sides of the pull plate are both provided with pull grooves, and the two pull grooves are arranged between the two arc-shaped cover plates.

[0011] As a preferred technical scheme of the utility model, the bottom end of the pull plate is provided with two sliding grooves, the inner walls of the two sliding grooves are both slidably connected with sliding columns, and the bottom ends of the two sliding columns are both fixed to the inner wall of the hemispherical column.

[0012] As a preferred embodiment of this utility model, the cross-sectional area of ​​the inner walls of the two sliding grooves is matched with the cross-sectional area of ​​the outer wall of the sliding column.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this solution, according to the required weight of the air spherical column, identical square load-bearing blocks are placed side by side on the top of the pull plate. The pull plate is slid along the outer wall of the sliding column fixed at the bottom of the inner wall of the hemispherical column using a groove at the bottom of the pull plate until the inner wall of the groove is completely engaged with the outer wall of the sliding column. Thus, the pull plate is completely inserted into the interior of the hemispherical column. This allows for the addition or reduction of load-bearing blocks as needed. At the same time, the pull plate can be quickly removed from the interior of the hemispherical column by the pull-out mechanism, thereby effectively improving the practicality of the device.

[0015] 2. This solution involves installing two arc-shaped cover plates on one side of the hemispherical column, using the inner wall of the protective sleeve to match the outer wall of the column, thus engaging one side of the connecting column with the inner wall of the column, while simultaneously fitting the outer wall of the connecting column with the inner wall of the protective sleeve. This increases the fit between the two sides of the hemispherical column, making the corners arc-shaped, preventing injuries to passersby. Furthermore, the protective sleeve provides better protection for the outer surface of the column, thereby increasing the service life of the device and improving its effectiveness.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a volleyball column, including a support column 1, an inner wall of the support column 1 with a telescopic rod 2, a connecting column 3 matchedly provided on the inner wall of the telescopic rod 2, a hemispherical column 4 fixed on one side of the connecting column 3, two wheels 5 provided on the outer wall of the hemispherical column 4, and a load-bearing installation mechanism 6 provided on the inner wall of the hemispherical column 4.

[0024] The load-bearing installation mechanism 6 includes:

[0025] A pull plate 61 is provided, the bottom end of which slides against the inner wall of the hemispherical column 4. Several square load-bearing blocks 62 are provided at the top of the pull plate 61. Pull grooves 63 are provided on both sides of the pull plate 61 to facilitate the quick pulling of the pull plate 61 from the inner wall of the hemispherical column 4. The two pull grooves 63 are both located between two arc-shaped cover plates 8. Two sliding grooves 64 are provided at the bottom of the pull plate 61. Sliding columns 65 slide on the inner wall of the two sliding grooves 64 to facilitate the stable sliding of the pull plate 61 on the inner wall of the hemispherical column 4 and to prevent misalignment between the outer wall of the pull plate 61 and the hemispherical column 4. The bottom ends of the two sliding columns 65 are fixed to the inner wall of the hemispherical column 4. The cross-sectional area of ​​the inner wall of the two sliding grooves 64 is matched with the cross-sectional area of ​​the outer wall of the sliding column 65.

[0026] As attached Figure 1 As shown, a protective sleeve 7 is provided on the outer wall of the support column 1.

[0028] Working principle: In use, according to the weight requirements of the air volleyball column, place the same square load-bearing blocks 62 side by side on the top of the pull plate 61. Use the sliding groove 64 opened at the bottom of the pull plate 61 to slide on the outer wall of the sliding column 65 fixed at the bottom of the inner wall of the hemispherical column 4 until the inner wall of the sliding groove 64 is completely engaged with the outer wall of the sliding column 65. Then, the pull plate 61 is completely inserted into the interior of the hemispherical column 4. Install the two arc-shaped cover plates 8 on one side of the hemispherical column 4 respectively. Use the inner wall of the protective sleeve 7 to match the outer wall of the support column 1. Engage one side of the connecting column 3 with the inner wall of the support column 1. At the same time, fit the outer wall of the connecting column 3 with the inner wall of the protective sleeve 7.
