Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, and more specifically, to a volleyball training device. Background Technology

[0002] The spiking technique of volleyball players is very important and directly affects the outcome of volleyball matches. Therefore, volleyball players often practice spiking. Currently, spiking training still requires the help of traditional human sparring. When a player practices spiking alone, the volleyball needs to be clamped in a volleyball training clamp by a human, who then holds the clamp to assist the player in spiking. This method requires two people to cooperate, which is quite cumbersome. Furthermore, holding the clamp manually is not only strenuous but also makes it difficult to maintain a stable and consistent spiking height, ultimately failing to improve the overall spiking training effect. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing technologies require two people to work together, which is time-consuming and laborious, and the overall training effect is not good. In order to overcome the above-mentioned defects of the existing technology, this invention provides a technology that can realize lifting and rotation adjustment, so as to adjust different heights and angles according to different team members, thereby improving the overall versatility and practicality.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted:

[0005] A volleyball training device includes a sliding base, a telescopic rod assembly, a connecting rod, a ball-clamping rod, and a spotlight. The telescopic rod assembly is vertically arranged, with its lower end fixedly connected to the sliding base and its upper end rotatably connected to the lower end of the connecting rod. The telescopic rod assembly and the connecting rod are locked together by a locking assembly. One end of the ball-clamping rod is detachably connected to the upper end of the connecting rod, and the other end of the ball-clamping rod is bent into a circle for clamping the volleyball. The spotlight is rotatably and adjustablely connected to the connecting rod and is used to mark the jump position for the players. This device, through the telescopic rod assembly, connecting rod, and locking assembly, allows for height and rotation adjustments, enabling different heights and angles to be adjusted for different players, improving overall versatility. Furthermore, it eliminates the need for two players; one person can complete the training, making it convenient and simple to operate while achieving better training results.

[0006] Preferably, the telescopic rod assembly includes an outer rod, an inner rod, and a locking screw. The outer rod is vertically fixed to the sliding base, and the inner rod is slidably connected inside the outer rod. A threaded hole is transversely provided on the outer wall of the outer rod, and the locking screw is threaded into the threaded hole. When locked, the inner end of the locking screw abuts against the outer wall of the inner rod. Telescopic adjustment is achieved through the outer and inner rods, making operation simple and convenient.

[0007] Preferably, the outer peripheral wall of the inner rod is provided with annular graduated grooves arranged at equal intervals along the vertical direction. These grooves display different corresponding heights, allowing for quicker adjustment to suit different teammates.

[0008] Preferably, the upper end of the inner rod is provided with horizontally distributed locking holes; the locking assembly includes a locking pin; the locking pin is horizontally inserted through the lower end of the connecting rod and is fixedly connected to the connecting rod. One end of the locking pin passes through the connecting rod and is inserted into the locking hole, and there is rotational frictional resistance between the locking pin and the locking hole, allowing the connecting rod to adjust its angle with the inner rod under external force. The rotational frictional resistance between the outer wall of the locking pin and the inner wall of the locking hole ensures that the outer wall of the locking pin will not rotate with respect to the locking hole when no external force is applied, allowing for adjustment when manually rotated, thus facilitating operation.

[0009] Preferably, the locking assembly further includes an angle plate; the angle plate is fixedly mounted on the upper end of the inner rod, and the center of the angle plate is aligned with the center of the locking pin. The angle plate has evenly spaced graduations along its circumference; when the inner rod and the connecting rod are on the same straight line, the corresponding graduation is 0°. The angle plate allows for convenient angle control and adjustment, enabling the selection of appropriate angles for different team members.

[0010] Preferably, a connecting post is provided at the upper end of the connecting rod along the direction of the connecting rod; the outer peripheral wall of the connecting post is provided with external threads; the end of the ball clamping rod that connects to the connecting rod is provided with internal threads, and the ball clamping rod and the connecting post are detachably connected by threads. The threaded connection facilitates a detachable structure while ensuring a fixed connection and robustness.

[0011] Preferably, the ball-clamping rod includes a straight section, a circular section, and a bent section. The straight section is aligned with the connecting rod, the circular section is a downward-curved circle, and the bent section bends away from its original circular trajectory, forming a ball-releasing opening parallel to the straight section after bending. The straight section facilitates connection with the connecting rod, enabling detachment while ensuring connection stability. The circular section adapts to the shape of the volleyball, and the ball-releasing opening allows the circular section to deform slightly during ball placement, facilitating ball insertion and securing.

[0012] Preferably, the outer wall of the ball clamp is also covered with a non-slip sleeve for securing the volleyball. By using a flexible material such as rubber or sponge for the non-slip sleeve, the volleyball can fit snugly against the sleeve when placed in the circular opening, facilitating its secure placement and ensuring stability and stability, preventing it from easily falling out.

[0013] Preferably, a fixing sleeve is fixedly installed on the outer wall of the connecting rod; a light frame is rotatably and adjustablely connected to the fixing sleeve; the illumination lamp is fixedly installed on the light frame. The fixing sleeve has a transverse rotating hole, into which the light frame is inserted laterally, thus enabling the rotational adjustment of the light frame. Furthermore, by fixing the illumination lamp to the light frame, the illumination position of the light lamp can be adjusted, facilitating a standard jump position and aiding in better spiking training.

[0014] Preferably, the sliding base is also equipped with a storage bin for storing volleyballs. The storage bin facilitates the storage of volleyballs, and allows for convenient retrieval of the balls directly from the storage bin when training is needed, saving time and effort.

[0015] In summary, the advantages of this utility model are that the device can achieve lifting and rotation adjustment through the telescopic rod assembly, connecting rod and locking assembly, so that different heights and angles can be adjusted according to different team members, improving the overall versatility. Moreover, it does not require two team members to cooperate, one person can complete the training, which is convenient and simple to operate, and can also achieve better training results.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 4 As shown, a volleyball training device includes a sliding base 1, a telescopic rod assembly 2, a connecting rod 3, a ball-clamping rod 4, and an illumination lamp 6. The telescopic rod assembly 2 is vertically oriented, with its lower end fixedly connected to the sliding base 1 and its upper end rotatably connected to the lower end of the connecting rod 3. The telescopic rod assembly 2 and the connecting rod 3 are locked together by a locking assembly 5. One end of the ball-clamping rod 4 is detachably connected to the upper end of the connecting rod 3, and the other end of the ball-clamping rod 4 is bent into a circle for clamping the volleyball. The illumination lamp 6 is rotatably and adjustablely connected to the connecting rod 3 and is used to mark the jump position for the players, further assisting them in precise spiking training. This device, through the telescopic rod assembly 2, the connecting rod 3, and the locking assembly 5, can achieve height and rotation adjustment, allowing for different heights and angles to be adjusted according to different players, improving overall versatility. Furthermore, it eliminates the need for two players; one person can complete the training, making it convenient and simple to operate while achieving better training results.

[0027] like Figure 1As shown, the telescopic rod assembly 2 includes an outer rod 21, an inner rod 22, and a locking screw 23. The outer rod 21 is vertically fixed to the sliding base 1, and the inner rod 22 is vertically slidably connected inside the outer rod 21. A threaded hole is horizontally provided through the outer wall of the outer rod 21, and the locking screw 23 is threaded into the threaded hole. When locked, the inner end of the locking screw 23 abuts against the outer wall of the inner rod 22. When unlocked, the inner rod 22 is raised and lowered within the outer rod 21. Telescopic adjustment is achieved through the outer rod 21 and the inner rod 22, making operation simple and convenient. Annular scale grooves 24 are arranged at equal intervals along the vertical direction on the outer peripheral wall of the inner rod 22. The annular scale grooves 24 can display different corresponding heights, allowing for quicker adjustment to suit different teammates.

[0028] like Figure 1 and Figure 2 As shown, the upper end of the inner rod 22 is provided with horizontally distributed lock holes; the locking assembly 5 includes a locking pin 51 and an angle plate 52; the locking pin 51 is horizontally inserted through the lower end of the connecting rod 3, and the locking pin 51 is fixedly connected to the connecting rod 3. One end of the locking pin 51 passes through the connecting rod 3 and is inserted into the lock hole, and there is rotational frictional resistance between the locking pin 51 and the lock hole, which allows the connecting rod 3 to adjust the angle between itself and the inner rod 22 under the action of external force. Through the rotational frictional resistance between the outer wall of the locking pin 51 and the inner wall of the lock hole, it is ensured that the outer wall of the locking pin 51 will not rotate with the lock hole when no external force is applied, and adjustment can be achieved when manual rotation is required, making operation convenient. Angle disc 52 is fixedly mounted on the upper end of inner rod 22, with its center aligned with the center of locking pin 51. Scale lines 53 are evenly distributed along the circumference of angle disc 52. When inner rod 22 and connecting rod 3 are on the same straight line, the value of the corresponding scale line 53 is 0°. Adjustment is made by rotating the disc to both sides around 0°. Angle disc 52 allows for convenient angle control and adjustment, enabling the selection of appropriate angles for different team members.
