Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, and in particular to a height-adjustable soccer goal. Background Technology

[0002] When installing a soccer goal, the most important thing is to ensure that the goal is level after installation. There should not be a large difference in height between the two sides, which would cause the goal to tilt.

[0003] Currently, the relatively advanced installation method for soccer goals in the industry involves first embedding the pre-embedded parts, visually estimating the approximate height difference between the two pre-embedded parts, roughly adjusting the height of the bolts inside the goalposts, and then placing the entire soccer goal into the pre-embedded parts. The drawbacks of this method are as follows: First, there is no precise height difference value, requiring multiple attempts to adjust the height to achieve a level soccer goal frame. Second, the soccer goal frame is quite heavy, requiring repeated removal of the pre-embedded parts during adjustment, which places a burden on on-site construction workers and increases construction costs. Furthermore, due to the overall weight, it is virtually impossible for customers to manually adjust the height of the soccer goal frame later on.

[0004] Therefore, this invention proposes a height-adjustable soccer goal. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a height-adjustable soccer goal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A height-adjustable soccer goal includes a goalpost and a goal tube embedded in the ground. The bottom of the goalpost is inserted into the goal tube, and a lifting groove is provided on the side of the goalpost. A lifting square tube is installed inside the goalpost by fixing bolts. A rocker arm is rotatably installed at the upper end of the lifting square tube, and the rocker arm corresponds to the lifting groove. A first lead screw is rotatably installed inside the lifting square tube near the top. A first bevel gear is installed at the upper end of the first lead screw. A second bevel gear is installed at one end of the rocker arm installed in the lifting square tube. The second bevel gear meshes with the first bevel gear. The inside of the lifting square tube is fitted with a sleeve, and the upper end of the sleeve is fixed with a first nut, which is threaded onto the first lead screw; the lower end of the sleeve is fitted with an insert rod, and the lower end of the insert rod is fixed on the base, which is placed on the first retaining ring, and the first retaining ring is fixed inside the goal tube.

[0008] Furthermore, a sliding groove is provided on the side of the lifting square tube, and a nut is installed on the side of the sleeve near the top. A bolt is threaded on the nut, and the bolt extends from the sliding groove to the outside of the lifting square tube, with the head diameter of the bolt being larger than the width of the sliding groove.

[0009] Furthermore, a sliding sleeve is installed at the bottom end of the lifting square tube, and the sliding sleeve is slidably fitted on the outside of the tube, with the tube and the sliding sleeve being slidably installed together.

[0010] Furthermore, the surface of the lifting square tube is bolted with ear plates, and probes are mounted on the ear plates.

[0011] Furthermore, it also includes multiple net tie rods installed behind the goalposts and tie rod conduits buried in the ground. The net tie rods are connected to the net via tie ropes. The lower end of the net tie rod is inserted into the tie rod conduit. A second retaining ring is fixed inside the tie rod conduit. A lower baffle, an upper baffle, and a second screw are provided between the lower part of the net tie rod and the second retaining ring. The lower end of the second screw is fixed at the center of the top surface of the lower baffle, and the upper end of the second screw extends through to the top of the upper baffle. A second nut is coaxially fixed at the center of the top and bottom surfaces of the upper baffle. The second nut is threadedly installed with the second screw.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention eliminates the need for repeatedly removing the entire soccer hoop, requires minimal construction personnel and equipment, and can be easily installed by just a few people, saving both time and effort. Furthermore, customers can easily adjust the hoop without external assistance during subsequent use, achieving a high degree of autonomy. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0017] Reference Figure 1-6 A height-adjustable soccer goal includes a goalpost 1 and a goal tube 2 buried in the ground. The bottom of the goalpost 1 is inserted into the goal tube 2. A lifting groove 11 is opened on the side of the goalpost 1. A lifting square tube 23 is installed in the goalpost 1 by fixing bolts 22. A rocker arm 21 is rotatably installed at the upper end of the lifting square tube 23, and the rocker arm 21 corresponds to the lifting groove 11. A first lead screw 29 is rotatably installed inside the lifting square tube 23 near the top. A first bevel gear 210 is installed at the upper end of the first lead screw 29. A second bevel gear 211 is installed at one end of the rocker arm 21 installed in the lifting square tube 23. The second bevel gear 211 meshes with the first bevel gear 210. A sleeve 27 is inserted inside the lifting square tube 23. A first nut 28 is fixed at the upper end of the sleeve 27. The first nut 28 is threadedly installed with the first lead screw 29. A rod 26 is inserted at the lower end of the sleeve 27. The lower end of the rod 26 is fixed on the base 25. The base 25 is placed on the first retaining ring 24, and the first retaining ring 24 is fixed inside the goal tube 2.

[0018] Furthermore, a groove 213 is provided on the side of the lifting square tube 23, and a nut is installed on the side of the sleeve 27 near the top. A bolt 212 is threaded on the nut. The bolt 212 extends from the groove 213 to the outside of the lifting square tube 23, and the head diameter of the bolt 212 is greater than the width of the groove 213.

[0019] Furthermore, a sliding sleeve 214 is installed at the bottom end of the lifting square tube 23. The sliding sleeve 214 is slidably sleeved on the outside of the sleeve 27, and the sleeve 27 and the sliding sleeve 214 are slidably installed.

[0020] Furthermore, ear plates 6 are bolted to the surface of the lifting square tube 23, and probes 7 are mounted on the ear plates 6. The net is installed together with the goalposts 1 and the probes 7.

[0021] Furthermore, it also includes multiple net tie rods 4 installed behind the goalposts 1 and tie rod conduits 5 buried in the ground. The net tie rods 4 are connected to the net through tie ropes 3. The lower end of the net tie rods 4 is inserted into the tie rod conduits 5. A second retaining ring 51 is fixed inside the tie rod conduits 5. A lower baffle 52, an upper baffle 53, and a second screw 55 are provided between the lower part of the net tie rods 4 and the second retaining ring 51. The lower end of the second screw 55 is fixed at the center of the top surface of the lower baffle 52, and the upper end of the second screw 55 extends through to the top of the upper baffle 53. A second nut 54 is coaxially fixed at the center of the top and bottom surfaces of the upper baffle 53. The second nut 54 is threadedly installed with the second screw 55.

[0022] The working principle of this invention is as follows:

[0023] Before installing the lower end of the goalpost 1 inside the goal tube 2, first insert the rod 26 and the base 25 into the goal tube 2, and place the rod 26 in the center of the first retaining ring 24 through the base 25. The center of the first retaining ring 24 can be provided with a through hole or a positioning recess to facilitate the centering of the base 25 and the rod 26. Then insert the goalpost 1 into the goal tube 2 and place the sleeve 27 aligned with the rod 26.

[0024] Before installing the lower end of the net tie rod 4 inside the tie rod embedding tube 5, first combine the second lead screw 55 with the upper baffle 53 and the second nut 54. Adjust the distance between the upper baffle 53 and the lower baffle 52 using the threaded engagement of the second lead screw 55 and the upper baffle 53. Then, place the lower baffle 52 onto the second retaining ring 51. A through hole or positioning recess can be provided in the center of the second retaining ring 51 to facilitate the centered placement of the lower baffle 52 and the second lead screw 55. Alternatively, the lower end of the second lead screw 55 can be designed to protrude from the bottom surface of the lower baffle 52, and a through hole or positioning recess can be provided in the center of the second retaining ring 51 to facilitate the centered placement of the lower baffle 52 and the second lead screw 55. After adjusting the distance between the lower baffle 52 and the upper baffle 53, they can be placed into the tie rod embedding tube 5. Then, insert the lower end of the net tie rod 4 into the tie rod embedding tube 5. At this point, the upper baffle 53 can support the net tie rod 4. By adjusting the distance between the upper baffle 53 and the lower baffle 52, the height of the net tie rod 4 can be adjusted, thereby providing different heights of tension and support for the net.

[0025] First, the goalpost 2 and the tie rod 5 are buried in the ground. Then, the goalpost 1 is inserted into the goalpost 2 and the net tie rod 4 is inserted into the tie rod 5. When adjusting the height of the goalpost 1, the second bevel gear 211 is meshed with the first bevel gear 210 by rotating the rocker arm 21, thereby controlling the rotation of the first lead screw 29. The first lead screw 29 is threadedly engaged with the first nut 28. Since the first nut 28 is fixed to the surface of the sleeve 27 and the sleeve 27 is restricted from rotating by the engagement of the bolt 212 and the nut, the rotation of the first lead screw 29 can control the lifting square tube 23, the first lead screw 29, and the rocker arm 21 to move up and down. The lifting square tube 23 is fixed to the goalpost 1 by the fixing bolt 22, so the goalpost 1 can be controlled to move up and down relative to the goalpost 2, thereby realizing the height adjustment of the goalpost 1. The adjustment process is simple and convenient. The ear plate 6 and the probe 7 also follow the goalpost 1 to realize the height adjustment.
