Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically an adjustable children's basketball hoop. Background Technology

[0002] Basketball hoops are a common piece of sports equipment in children's sports activities, playing an important role in cultivating children's interest and ability in sports. However, existing children's basketball hoops have some significant problems in their use.

[0003] Regarding height adjustment, traditional children's basketball hoops are often fixed in height or have complex adjustment methods. For children of different ages and heights, fixed-height basketball hoops cannot meet their actual needs. Younger and shorter children find it difficult to complete shooting motions when using standard-height basketball hoops, which not only dampens their enthusiasm for basketball but may also lead to frustration due to repeated failed attempts. For older and taller children, fixed-height basketball hoops cannot meet their challenge of making more difficult shots. Even if some basketball hoops have height adjustment functions, the adjustment methods may involve complicated tools or operating procedures, which is extremely inconvenient for children and their parents, reducing the practicality and applicability of the basketball hoop.

[0004] For example, in a height-adjustable children's basketball hoop with announcement number CN205386318U, a connecting rod is embedded in the center of the front end of the upper surface of the base, and the lower end of the connecting rod is connected to the left and right sides by diagonal support rods. Elastic pressure blocks are evenly spaced at the upper end of the connecting rod, and the lower end of the connecting rod at the elastic pressure block has external threads. A telescopic rod is located inside the connecting rod, and a locking screw is located at the bottom of the outer side of the telescopic rod. In use, the height of the aforementioned children's basketball hoop is fixed or its adjustment is complex, failing to meet the needs of different children and affecting their enthusiasm for use and skill development. However, it still has its limitations. Other issues include the lack of anti-tipping design in existing children's basketball hoops. Children may collide with or pull on the basketball hoop while using it, or the hoop's center of gravity may shift after height adjustments, all of which could affect its stability. If the hoop tipps over, it could cause serious injury to nearby children. Many basketball hoops rely solely on the weight of their base for balance, which is often ineffective in preventing tipping during vigorous play or accidental collisions, posing a significant safety hazard to children. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable children's basketball hoop to solve the problems mentioned in the background art, such as children's basketball hoops having fixed or complicated height adjustments that cannot meet the needs of different children, affecting their enthusiasm for use and skill development, and children's basketball hoops having insufficient anti-tipping design that are prone to tipping over due to external forces, threatening children's safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable children's basketball hoop, comprising a fixed column and an adjusting column nested inside the upper end of the fixed column; a ball receiving plate is fixedly installed on the left side of the upper end of the adjusting column, a rotating shaft is rotatably installed on the upper right end of the fixed column, and a rotating handle is fixedly installed on the right end of the rotating shaft; a height adjustment mechanism is provided at the upper end of the fixed column, and a placement groove is opened at the right end of the adjusting column; a fixed plate is fixedly installed at the lower end of the fixed column, a support plate is provided at the lower end of the fixed plate, and two support plates are evenly distributed around the fixed plate as the center of symmetry; an anti-tipping mechanism is provided at the lower end of the fixed plate, and a limit cylinder is installed on the left side of the upper end of the support plate, and four limit cylinders are evenly distributed around the fixed plate as the center of symmetry.

[0007] Furthermore, the height adjustment mechanism includes a spur rack fixedly installed at the front end of the placement slot, and a spur gear fixedly installed at the left end of the rotating shaft.

[0008] Furthermore, the spur gear is installed inside the placement slot, and the spur rack meshes with the spur gear.

[0009] Furthermore, the anti-tipping mechanism includes a push block disposed inside the limiting cylinder, and a first spring is disposed at the lower end of the push block, with the lower end of the first spring disposed at the lower end of the limiting cylinder.

[0010] Furthermore, a movable rod is installed on the ball on the lower left side of the fixed plate, and the lower end of the movable rod is fixedly installed on the upper end of the push block. A connecting rod is installed on the ball on the lower front side of the fixed plate, and four connecting rods are evenly distributed with the fixed plate as the center of symmetry.

[0011] Furthermore, a sliding block is installed on the lower ball of the connecting rod, and a pressing block is provided at the lower end of the sliding block; a guide groove is provided on the support plate.

[0012] Furthermore, the squeezing block at the lower end of the sliding block is installed inside the guide groove, and a second spring is installed inside the guide groove, with the right end of the second spring installed at the left end of the sliding block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the height of the receiving board needs to be adjusted, the user turns the handle. Turning the handle drives the rotating shaft, which in turn drives the spur gear. The spur gear meshes with the spur rack inside the placement slot, causing the spur gear to move the spur rack up and down. The spur rack then moves the adjusting column inside the fixed column up and down, thereby moving the receiving board up and down for adjustment. This height adjustment method, using a spur gear and spur rack, allows for precise adjustment of the basketball hoop height according to the different heights of children.

[0015] Furthermore, both young and older children can find a basketball hoop height that suits them, allowing them to better participate in basketball, improve their shooting accuracy, and enhance their interest and confidence in the sport. The simple operation method enables them to adjust the basketball hoop height independently, increasing their sense of participation and autonomy in the game.

[0016] Furthermore, the convenient adjustment method saves time and effort, improves the efficiency of basketball hoop use, and a basketball hoop of appropriate height can ensure the safety of children during exercise, avoiding accidental injuries caused by basketball hoops that are too high or too low. Basketball hoops adapted to the height of children at different stages help them better develop basketball skills, gradually transitioning from simple close-range shooting to long-range shooting, constantly challenging themselves, improving their athletic ability, and promoting the physical and mental health development of children.

[0017] 2. When the fixed column and adjusting column shake, the lower end of the fixed plate will push the movable rod, which in turn pushes the push block. The push block pushes the first spring inside the limiting cylinder, thereby buffering the shaking. The connecting rod at the lower end of the fixed plate will push the sliding block installed on the guide groove. The pressing block at the lower end of the sliding block will press the second spring inside the guide groove, thereby buffering the shaking and effectively reducing the risk of the basketball hoop tipping over due to various reasons.

[0018] Furthermore, when children collide or pull while using the basketball hoop, or when the center of gravity changes after the height of the basketball hoop is adjusted, the system can quickly buffer external forces, maintain the stability of the basketball hoop, and prevent it from tipping over, thereby avoiding accidental injuries to children. It can also reduce damage to the basketball hoop structure caused by slight shaking and other factors during long-term use. Attached Figure Description
