[0002] The high-toughness and wear-resistant ball machine protective cover is an external protective device specifically designed for ball machines. Made of high-toughness and wear-resistant materials, it can effectively resist external impacts and wear. It not only protects the delicate internal components of the ball machine from damage, but also extends the service life of the equipment. In addition, this protective cover is usually lightweight, easy to install and remove, and suitable for various training and competition environments, ensuring the safety and reliability of the ball serving process.
[0003] When using the high-toughness and wear-resistant ball-launching machine protective cover, the hopper and the main body of the protective cover are connected by multiple bolts during installation. Disassembly takes more time and requires tools, making it very inconvenient. Therefore, the market needs a new device to solve the current problems. Utility Model Content
[0004] The purpose of this utility model is to provide a high-toughness and wear-resistant protective cover for a ball-serving machine, in order to solve the problem that, in the above-mentioned high-toughness and wear-resistant protective cover for a ball-serving machine, the hopper and the main body of the protective cover are connected by multiple bolts during installation, which takes more time to disassemble and requires tools to disassemble, making the operation very inconvenient. Therefore, the market needs a new device to solve the current problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-toughness and wear-resistant protective cover for a ball-serving machine, comprising a protective cover body, a hopper installed at the upper end of the protective cover body, insertion holes provided at the lower ends of the hopper, and through circular holes provided at the upper inner ends of the left and right ends of the protective cover body, with the center of the through circular holes aligned with the center of the insertion holes. A fixing cylinder is fixed at the upper ends of the left and right ends of the protective cover body, and sliding grooves are provided on the left and right sides of the fixing cylinder. A connecting ring is sleeved on the outer side of the fixing cylinder through the sliding grooves. A circular plate is fixed at the inner side of the connecting ring, and the circular plate is sleeved on the inner side of the fixing cylinder. An insertion post is fixed at the lower end of the circular plate, and a stainless steel spring is fixed at the upper end of the circular plate.
[0006] Preferably, a base plate is provided at the lower end of the main body of the protective cover, and the lower end of the base plate is provided with a plurality of T-shaped grooves at the inner side.
[0007] Preferably, a counterweight is fitted onto the inner side of each T-shaped groove, and the counterweight is engaged with the inner position of the T-shaped groove by its shape and structure.
[0008] Preferably, a ball-out pre-drilling hole is provided at the front end of the main body of the protective cover, and the shape and structure of the ball-out pre-drilling hole are set to a square structure.
[0009] Preferably, the hopper has a vent at the front end and a handle is fixed at the rear end of the hopper.
[0010] Preferably, the hopper is installed at the upper end of the protective cover body, and the interior of the hopper is in communication with the interior of the protective cover body.
[0011] Preferably, the sleeve ring can be moved along the outer wall of the fixed cylinder by manual control, and the groove limits the movement distance of the sleeve ring.
[0012] Preferably, the movement of the sleeve ring drives the circular plate to move, the circular plate controls the movement of the insertion post, and the circular plate, through the elastic force of the stainless steel spring, causes the insertion post to pass through the circular hole and be inserted into the insertion hole.
[0013] Compared with the prior art, this utility model provides a high-toughness and wear-resistant protective cover for a ball-serving machine, which has the following beneficial effects:
[0014] 1. When using this device, insert the bottom of the hopper into the upper part of the protective cover body. During insertion, pull the sleeve ring outward so that the insertion post is inside the fixed cylinder. At this time, align the center of the round hole with the center of the insertion hole. Release the sleeve ring to release the elastic force of the stainless steel spring, and let the insertion post pass through the round hole into the inner position of the insertion hole, thus completing the installation of the hopper. This method allows for quick installation and disassembly without the need for tools.
[0015] 2. Traditional protective covers are too light at the bottom, which makes the center of gravity of the protective cover unstable. This device has a T-shaped groove on the inner side of the base plate, and the counterweight is designed with a T-shaped structure so that the counterweight can be snapped into the inside of the T-shaped groove. This allows for easy installation and removal, thereby increasing the flexibility of the equipment. Attached Figure Description
