Description

Technical Field

[0001] This utility model relates to a height adjustment device, and more particularly to a volleyball net height adjustment device, belonging to the field of sports equipment technology. Background Technology

[0002] Volleyball is a ball sport in which players use both hands to perform actions such as serving, setting, passing, spiking, and blocking to organize offense and defense. A net is set up above the center line of the court, with a width of 1 meter and a length of 9.50 meters. It is hung on two posts outside the court. The net height is 2.24 meters for women and 2.43 meters for men. There are 5-centimeter-wide marker tapes at both ends of the net, perpendicular to the intersection of the sideline and the center line. A 1.80-meter-long marker pole is attached to the outside of each of these tapes.

[0003] Chinese patent publication (CN202021702667.3) discloses a height-adjustable volleyball net frame, which uses two electric hydraulic cylinders to synchronously raise and lower the net to achieve automatic height adjustment, making the net height suitable for people of different heights and allowing the same volleyball court to meet the needs of people of different heights. However, using electric hydraulic cylinders to adjust the height of the volleyball net increases the production cost of the volleyball frame and increases the overall weight of the volleyball frame, resulting in poor overall portability. The adjustment requires power support, which limits the application scenarios.

[0004] To solve the above-mentioned technical problems, a volleyball net height adjustment device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a volleyball net height adjustment device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown, this utility model embodiment provides a volleyball net height adjustment device, which consists of a support mechanism 10, a connecting mechanism 20, and a net 24.

[0030] The support mechanism 10 includes two support rods 11, which are symmetrically arranged on both sides of the net 24. The inside of the support rod 11 is provided with an annular groove 31 along its circumference, and multiple sets of annular grooves 31 are provided at equal intervals along its height. The inside of the support rod 11 is provided with a vertical groove 32 along its circumference, and multiple sets of vertical grooves 32 are provided at equal intervals along its height. The vertical grooves 32 are connected to the annular grooves 31 and are arranged in a cross shape. One side of the support rod 11 is engaged with a limiting plate 17, and one side of the limiting plate 17 is fixedly connected with a limiting strip 18. The limiting strip 18 is engaged with the vertical grooves 32. One side of the limiting plate 17 is threadedly connected with four fixing bolts 19, and one end of the fixing bolts 19 is threadedly connected to the support rod 11.

[0031] In one embodiment, to enhance the stability of the support rod 11, a stabilizing frame 13 is hinged to both sides of the support rod 11. When the stabilizing frame 13 is unfolded, it contacts the ground. Fixing holes 15 are evenly distributed on one side of the stabilizing frame 13. Conical fasteners, positioning pins, or fixing nails can be installed through the fixing holes 15. The conical fasteners, positioning pins, and fixing nails pass through the fixing holes 15 and one end is embedded in the ground to fix the position of the stabilizing frame 13. A counterweight 14 is provided on one side of the stabilizing frame 13. The counterweight 14 fixes the stabilizing frame 13 when the fixing cone cannot be installed, preventing the support rod 11 from becoming unstable.

[0032] In one embodiment, in order to reduce the space occupied by the stabilizer 13 when carried, storage slots 35 are provided on both sides of the support rod 11, and a collar 12 is fitted on one side of the support rod 11. The collar 12 limits the stabilizer 13 when it is put into the storage slot 35.

[0033] In one embodiment, to facilitate carrying the support rods 11, a connecting seat 16 and a insert plate 34 are fixedly connected to one side of each of the two support rods 11. The insert plate 34 engages with the connecting seat 16, and the two support rods 11 are assembled into one unit by the insert plate 34 and the connecting seat 16, which facilitates carrying and transportation.

[0034] The connecting mechanism 20 includes a connecting rod 21 and a fixing block 23. The connecting rod 21 is symmetrically arranged on both sides of the net 24 and inserted into the support rod 11. The fixing blocks 23 are evenly distributed and fixedly connected to one side of the connecting rod 21. The fixing blocks 23 are arranged in a cross shape and are slidably connected to the support rod 11 through an annular groove 31.

[0035] In one embodiment, the support rod 11 and the connecting rod 21 are hollow inside to reduce the overall weight, and a drainage hole 33 is provided at the bottom of the support rod 11 to facilitate the drainage of internal water.

[0036] In one embodiment, to facilitate the connection and fixation of the net 24 and the connecting rod 21, a connector 22 is symmetrically fixedly connected to one side of the connecting rod 21, and the net 24 is fixedly connected to the connector 22.

[0037] In operation, the two support rods 11 are joined together, with the insert plate 34 on one side of one support rod 11 inserted into the connecting seat 16 of the other support rod 11. The two support rods 11 are then assembled into a single unit for carrying and use. When in use, the support rods 11 are separated and placed in the designated position. The upward-moving collar 12 releases the restriction on the stabilizer 13 in the storage slot 35, allowing the stabilizer 13 to unfold and contact the ground. In soft ground, the fixing cone can be inserted through the fixing hole 15 to secure the stabilizer 13. If the ground does not allow the fixing cone to be inserted, a counterweight 14 is placed on the stabilizer 13 to fix its position. The net 24 is then connected to the connector. 22 is connected and fixed to the connecting rod 21. The limiting plate 17 is removed. The connecting rod 21 is rotated so that the fixing block 23 on one side of the connecting rod 21 slides from the annular groove 31 into the vertical groove 32. The connecting rod 21 is moved vertically to adjust the height of the connecting rod 21, thereby adjusting the height of the net 24. After adjustment, the connecting rod 21 is rotated so that the fixing block 23 slides into the annular groove 31. At this time, the fixing block 23 and the connecting rod 21 cannot move up or down. The limiting plate 17 is connected to the support rod 11 through the fixing bolt 19 so that the limiting strip 18 on one side of the limiting plate 17 is inserted into the vertical groove 32, so that the fixing block 23 on one side of the connecting rod 21 cannot enter the vertical groove 32, thus fixing the height of the connecting rod 21.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
