Description

Technical Field

[0001] The utility model relates to the field of ball training devices, and particularly relates to a ball hitting training device. Background Art

[0002] Table tennis is a world-famous ball sports project, and its audience group in China is very extensive. In order to improve table tennis skills, people have invented many table tennis training devices. Generally, a table tennis training device includes a base, a vertical rod, and a table tennis ball. The base is placed on the ground, and by hitting the table tennis ball, the elastic force of the vertical rod is used to make the hit table tennis ball sway back and forth, so as to achieve the effect of simulating single-person table tennis hitting.

[0003] However, the structure of the existing training device prevents the training device from tipping over by the weight of the base, and it can only be used with balls of relatively small mass, such as table tennis balls. When using balls of relatively large mass, the movement of the ball after being hit easily causes the base to tip over. At the same time, the training device cannot be installed on walls or other positions for use. Therefore, there is still room for optimization in the existing ball training devices. Content of the Utility Model

[0004] An object of the utility model is to provide a ball hitting training device to solve the above problems.

[0005] To achieve the above object of the utility model, the utility model is realized through the following technical solutions:

[0006] A ball hitting training device includes a base, a first vertical rod, a second vertical rod, and a ball. The base is provided with a fixing mechanism, and the fixing mechanism fixedly installs the base at the to-be-installed position. The lower end of the first vertical rod is installed on the base and extends upward. The first vertical rod is tubular and provided with a positioning mechanism at the top. The second vertical rod is inserted downward into the first vertical rod, and the positioning mechanism positions the second vertical rod at a preset position. The ball is provided with an installation groove, and the top of the second vertical rod is inserted into the installation groove to be fixedly connected with the ball. The second vertical rod is made of an elastic material. When hitting the ball, the ball moves in the first direction to drive the second vertical rod to deform and bend in the first direction. When the second vertical rod deforms to the limit position, it resets and deforms in the second direction opposite to the first direction, and drives the ball to move in the second direction to simulate hitting. By setting a fixing mechanism on the base to fix the base at horizontal or non-horizontal to-be-installed positions such as the ground and the wall for use, and the setting of the fixing mechanism increases the connection stability between the base and the to-be-installed position, so that the training device can be used to simulate various balls such as table tennis and tennis, the functions of the product are more diversified, and the use interest is enhanced. At the same time, the setting of the positioning mechanism, the first vertical rod, and the second vertical rod can freely adjust the length of the second vertical rod and the height of the ball according to the height or needs of the user, and adjust the hitting movement distance of the ball.

[0007] Preferably, the fixing mechanism is set as a suction cup. A dome-shaped cavity is provided on the bottom surface of the base, and the suction cup is installed in the cavity. An adjustment hole is provided at the top of the suction cup, and an adjustment rod is provided in the adjustment hole. The base is provided with a connection hole penetrating through the upper and lower parts. The upper end of the adjustment rod passes through the connection hole and communicates with the outside. By controlling the adjustment rod, the middle part of the suction cup can be deformed upward or downward, and the suction cup can form negative pressure adsorption fixation with the installation position to be installed or be disassembled and separated from the installation position to be installed. Using the suction cup to fix between the base and the installation position to be installed can reduce the weight of the base, facilitate carrying, and also reduce the transportation cost; the cooperation of the adjustment rod and the adjustment hole is used to realize the adsorption fixation and disassembly of the suction cup, making the use more stable and convenient.

[0008] Preferably, the connection hole is directly below the first vertical rod, and the lower end of the first vertical rod is connected to the adjustment rod. Rotating or moving the first vertical rod up and down can control the movement of the adjustment rod, so that the suction cup is fixed or separated from the installation position to be installed. Using the first vertical rod to control the movement of the adjustment rod can reduce the accessories and make the use more convenient.

[0009] Preferably, the adjustment rod is set as a screw rod, and the adjustment hole is provided with internal threads. The rotation of the first vertical rod drives the screw rod to rotate to adjust the relative position between the middle part of the suction cup and the installation position to be installed, so that the suction cup is fixed or separated from the installation position to be installed. By rotating the adjustment rod to adjust the air pressure inside and outside the suction cup, the fixation and disassembly of the suction cup are realized. Compared with the up and down movement adjustment, it can avoid the up and down movement of the adjustment rod caused by the movement of the sphere and the first vertical rod when hitting the sphere, so that the suction cup is loosened.

[0010] Preferably, the width of the suction cup in at least one direction is greater than the width of the base in the same direction. When the suction cup is adsorbed and fixed to the installation position to be installed, the edge of the suction cup extends out from the base, and the outer periphery of the base abuts against the suction cup, clamping the suction cup between the base and the installation position to be installed. Using the base to abut and press the suction cup can prevent the outer edge of the suction cup from warping and admitting air, resulting in the detachment of the suction cup.

[0011] Preferably, the positioning mechanism includes an upper locking sleeve and a lower locking sleeve. The upper locking sleeve is provided with an upper locking hole penetrating through the upper and lower parts. The lower locking sleeve is provided with a lower locking hole penetrating through the upper and lower parts. A flexible body is arranged between the upper locking sleeve and the lower locking sleeve. The flexible body is provided with a middle locking hole penetrating through the upper and lower parts. The upper locking hole, the lower locking hole and the middle locking hole are located on the same straight line. The upper end of the first vertical rod is inserted into the lower locking hole for positioning. The lower end of the second vertical rod passes through the upper locking hole, the middle locking hole and the lower locking hole and enters the first vertical rod. By actively changing the relative position between the upper locking sleeve and the lower locking sleeve, the flexible body deforms to change the pressing force between the flexible body and the second vertical rod, so that the second vertical rod is fixed relative to the first vertical rod or can move up and down. Through the connection of the upper locking sleeve, the lower locking sleeve and the flexible body, the extended length of the second vertical rod can be freely adjusted to adjust the height of the sphere. The structure is simple and the adjustment is convenient.

[0012] Preferably, the upper end of the lower locking hole is provided with a resisting top extending into the hole. The upper end of the first vertical rod is provided with a resisting groove. The resisting top is inserted into the resisting groove, so that the lower locking sleeve and the first vertical rod are circumferentially fixed and the lower locking sleeve is prevented from moving downward relative to the first vertical rod. Through the resisting top and the resisting groove, the lower locking sleeve and the first vertical rod can be circumferentially fixed and limited downward at the same time.

[0013] Preferably, the flexible body is provided with an extension part. The extension part passes through the upper locking hole and is located above the upper locking sleeve. When the second vertical rod deforms, the extension part is located between the second vertical rod and the upper locking sleeve to form a protective layer. Since the upper locking sleeve is made of rigid material, when the second vertical rod deforms during use, the second vertical rod will contact the upper locking sleeve, and the second vertical rod is likely to be worn or broken. The setting of the extension part can be used for buffering when the second vertical rod deforms to form a protection and extend the service life of the second vertical rod.

[0014] Preferably, a retaining cap is arranged between the second vertical rod and the sphere. The retaining cap covers the second vertical rod and the sphere. A retaining pin is arranged between the retaining cap and the second vertical rod for fixed connection. This facilitates the disassembly and replacement of the sphere.

[0015] Preferably, the sphere is set as an elastic ball, a table tennis ball or an inflated ball.

[0016] The advantages of the present utility model are as follows: By setting a fixing mechanism on the base to fix the base on horizontal or non-horizontal installation positions such as the ground and the wall, and the setting of the fixing mechanism increases the connection stability between the base and the installation position, enabling the trainer to be used for simulating various ball games such as table tennis and tennis, making the functions of the product more diverse and enhancing the usage interest; at the same time, the setting of the positioning mechanism, the first vertical rod and the second vertical rod can freely adjust the length of the second vertical rod and the height of the ball according to the height or needs of the user, and adjust the distance of the ball hitting movement; the use of the suction cup to fix between the base and the installation position can reduce the weight of the base, facilitate carrying, and also reduce the transportation cost; the cooperation of the adjusting rod and the adjusting hole is used to realize the adsorption fixation and disassembly of the suction cup, making the use more stable and convenient; the base is used to press the suction cup tightly to prevent the outer edge of the suction cup from warping and admitting air, resulting in the detachment of the suction cup.

[0026] like Figures 1-7 A ball hitting training device includes a base 1, a first upright pole 2, a second upright pole 3 and a sphere 4. The base 1 is provided with a fixing mechanism, which fixes the base 1 to the position to be installed. The lower end of the first upright pole 2 is installed on the base 1 and extends upward. The first upright pole 2 is made of rigid material and is tubular. A positioning mechanism 5 is provided on the top. The second upright pole 3 is inserted downward into the first upright pole 2. The positioning mechanism 5 positions the second upright pole 3 in a preset position. A mounting groove 6 is provided on the sphere 4. The top of the second upright pole 3 is inserted into the mounting groove 6 and fixedly connected with the sphere 4. The second upright pole 3 is made of elastic material. When the sphere 4 is hit, the sphere 4 moves in the first direction, driving the second upright pole 3 to deform and bend in the first direction. The second upright pole 3 deforms to the limit position and resets the deformation in the second direction opposite to the first direction, and drives the sphere 4 to move in the second direction to simulate hitting.

[0027] In this embodiment, the installation location can be a horizontal or non-horizontal location such as the ground, a table, or a wall. Compared with the existing method of achieving horizontal placement by the weight of the base 1, by providing a fixing mechanism on the base 1, the trainer can be installed in more locations, and the ball 4 can be replaced with balls of different sizes and weights, such as table tennis, elastic balls, inflatable balls, etc., to simulate ball sports such as table tennis, tennis, volleyball, and football.

[0028] In this embodiment, the upper and lower positions, heights, etc. are all as follows Figure 1As shown in the description of the state when placed in the horizontal position, the first direction and the second direction refer to that when the ball 4 is hit forward, the second vertical rod 3 first deforms forward, and after reaching the extreme position, the second vertical rod 3 resets and deforms backward and continues to deform backward according to inertia. The front and back directions are the first direction and the second direction. Of course, when the hitting is continued, due to the changes in the direction of multiple hits, the first direction and the second direction are not opposite directions on the same straight line. The opposite of the first direction and the second direction in this embodiment refers to being roughly opposite, and does not necessarily mean being absolutely opposite on the same straight line.

[0029] The second upright pole 3 in this embodiment is made of glass fiber material and is provided with rubber coating on the outside. In other embodiments, the second upright pole 3 may not adopt the rubber coating structure, or may be made of other elastic materials.

[0030] The fixing mechanism in this embodiment is configured as a suction cup 7. The bottom surface of the base 1 is provided with a dome-shaped cavity 8. The suction cup 7 is installed in the cavity 8. The top of the suction cup 7 is provided with an adjustment hole 9. The adjustment hole 9 is provided with an adjustment rod 10. The base 1 is provided with a connecting hole 11 running through from top to bottom. The upper end of the adjustment rod 10 passes through the connecting hole 11 and communicates with the outside world. The adjustment rod 10 is controlled to deform the middle part of the suction cup 7 upward or downward. The suction cup 7 can be fixed to the position to be installed by forming a negative pressure adsorption or be disassembled and separated from the position to be installed. Compared with the traditional press-type suction cup, the suction cup 7 in this embodiment has an adjustment rod 10 to adjust the deformation and air pressure, and is less likely to loosen due to air intake after being fixed.

[0031] Preferably, the connecting hole 11 is located directly below the first vertical pole 2, and the lower end of the first vertical pole 2 is connected to the adjusting rod 10. Rotating or moving the first vertical pole 2 up and down can control the movement of the adjusting rod 10, so that the suction cup 7 is fixed to or separated from the installation position. Using the first vertical pole 2 to control the movement of the adjusting rod 10 can reduce accessories and is more convenient to use.

[0032] In this embodiment, the adjusting rod 10 is set as a screw rod, and the adjusting hole 9 is provided with an internal thread. The rotation of the first vertical rod 2 drives the screw rod to rotate to adjust the relative position of the middle of the suction cup 7 and the position to be installed, so that the suction cup 7 is fixed or separated from the position to be installed. The air pressure inside and outside the suction cup 7 is adjusted by rotating the adjusting rod 10 to achieve the fixation and removal of the suction cup 7. Compared with the up and down movable adjustment, it can avoid the movement of the sphere 4 and the first vertical rod 2 when hitting the sphere 4, causing the adjusting rod 10 to move up and down, thereby loosening the suction cup 7.

[0033] The width of the suction cup 7 in at least one direction is greater than the width of the base 1 in the same direction. When the suction cup 7 is adsorbed and fixed to the installation position, the edge of the suction cup 7 extends from the base 1, and the outer periphery of the base 1 abuts against the suction cup 7, clamping the suction cup 7 between the base 1 and the installation position. The base 1 is used to abut and press the suction cup 7 to prevent the outer edge of the suction cup 7 from warping and admitting air, resulting in the detachment of the suction cup 7. In this embodiment, the shapes of the base 1 and the suction cup 7 are both circular, and the diameter of the suction cup 7 is greater than the diameter of the base 1. In other embodiments, if the base 1 and the suction cup 7 are set to other shapes, it can be understood that the size of the suction cup 7 in a certain same direction is greater than the width of the base 1, so that the base 1 can press the edge of the suction cup 7. The width sizes of the suction cup 7 and the base 1 in this embodiment refer to the sizes in the state where the suction cup 7 is adsorbed to the installation position. Since the size of the suction cup 7 during adsorption is greater than the size after loosening and disassembly, the size of the suction cup 7 when not adsorbed can be equivalent to that of the base 1 or slightly smaller than the size of the base 1, and only need to satisfy that the size of the suction cup 7 during adsorption is greater than the base 1.

[0034] In the above embodiment, the positioning mechanism 5 includes an upper locking sleeve 12 and a lower locking sleeve 13. The upper locking sleeve 12 is provided with an upper locking hole 14 penetrating up and down, the lower locking sleeve 13 is provided with a lower locking hole 15 penetrating up and down, and a flexible body 16 is provided between the upper locking sleeve 12 and the lower locking sleeve 13. The flexible body 16 is provided with a middle locking hole 17 penetrating up and down. The upper locking hole 14, the lower locking hole 15 and the middle locking hole 17 are located on the same straight line. The upper end of the first vertical rod 2 is inserted into the lower locking hole 15 for positioning, and the lower end of the second vertical rod 3 passes through the upper locking hole 14, the middle locking hole 17 and the lower locking hole 15 and enters the first vertical rod 2, changing the relative position between the upper locking sleeve 12 and the lower locking sleeve 13. The flexible body 16 deforms to change the pressing force between the flexible body 16 and the second vertical rod 3, so that the second vertical rod 3 is fixed relative to the first vertical rod 2 or can move up and down.

[0035] In this embodiment, the upper locking sleeve 12 and the lower locking sleeve 13 are threadedly connected. When the upper locking sleeve 12 and the lower locking sleeve 13 are rotationally locked, the cavity between the upper locking sleeve 12 and the lower locking sleeve 13 shrinks, and the flexible body 16 is squeezed and deformed toward the middle locking hole 17. The friction or pressing force between the flexible body 16 and the second vertical rod 3 increases, and the second vertical rod 3 cannot move up and down. When unlocking, the upper locking sleeve 12 and the lower locking sleeve 13 are rotated to loosen, the cavity between the upper locking sleeve 12 and the lower locking sleeve 13 becomes larger, the friction or pressing force between the flexible body 16 and the second vertical rod 3 shrinks, and the second vertical rod 3 can move up and down or be pulled out as a whole. In other embodiments, the upper locking sleeve 12 and the lower locking sleeve 13 can also adopt structures such as snap fixation. This embodiment does not further limit the specific locking structure of the upper locking sleeve 12 and the lower locking sleeve 13, and only requires that the connection structure between the two can change the volume of the cavity between the upper locking sleeve 12 and the lower locking sleeve 13 during installation and disassembly.

[0036] Preferably, a top supporting part 18 extending into the hole is provided at the upper end of the lower lock hole 15, and a top supporting groove 19 is provided at the upper end of the first vertical rod 2. The top supporting part 18 is inserted into the top supporting groove 19 to circumferentially fix the lower locking sleeve 13 and the first vertical rod 2 and prevent the lower locking sleeve 13 from moving downward relative to the first vertical rod 2.

[0037] In this embodiment, the flexible body 16 is provided with an extension part 20. The extension part 20 passes through the upper lock hole 14 and is located above the upper locking sleeve 12. When the second vertical rod 3 deforms, the extension part 20 is located between the second vertical rod 3 and the upper locking sleeve 12 to form a protective layer. Since the upper locking sleeve 12 is made of a rigid material, when the second vertical rod 3 deforms during use, the second vertical rod 3 will contact the upper locking sleeve 12, and the second vertical rod 3 is likely to be worn or broken. The setting of the extension part 20 can be used for buffering when the second vertical rod 3 deforms to form protection and extend the service life of the second vertical rod 3.

[0038] An anti - detachment cap 21 is provided between the second vertical rod 3 and the sphere 4. The anti - detachment cap 21 covers the second vertical rod 3 and the sphere 4, and an anti - detachment pin is provided for fixed connection between the anti - detachment cap 21 and the second vertical rod 3.

[0039] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent substitution on some of the technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
