Description

Technical Field

[0001] The utility model relates to the technical field of sports training equipment, in particular to a spike launching device used for volleyball blocking training. Background Art

[0002] Volleyball is one of the most familiar ball games. Athletes usually need some auxiliary equipment to help them with their daily training. Different training items require different auxiliary training devices. Volleyball blocking auxiliary training devices are important equipment to improve the strength of athletes.

[0003] Blocking is one of the most effective means to deal with spikes. Volleyball players use spike launchers to simulate spikes for blocking training, but existing spike launchers can only serve in one direction. Athletes perform blocking training on the volleyballs served, which leads to a single training method and cannot well train the athletes' reaction ability. At the same time, the spike launcher has the same serving speed each time, which is not convenient for serving with different strengths according to the spike intensity required by the trainees.

[0035] See also Fig. 9The volleyball limiting mechanism 1 56 and the volleyball limiting mechanism 2 57 have the same structure, and the volleyball limiting mechanism 1 56 and the volleyball limiting mechanism 2 57 are symmetrically arranged front to back. The volleyball limiting mechanism 1 56 includes a volleyball pushing block 561, a movable shaft 1 562, a bare rod 2 563, a connecting pipe 2 564, a limiting rod 1 565, a limiting block 566, a limiting plate 2 567 and a guide groove 2 568. The movable shaft 1 562 is vertically fixed to the inner front side of the volleyball pushing block 561, and the bare rod 2 563 is fixed to the front end of the volleyball pushing block 561. The outer wall of the second 563 is provided with a connecting tube 564, the left end of the connecting tube 564 is fixedly connected to the limiting rod 565, the left side of the limiting rod 565 horizontally passes through the limiting block 566, the inner wall of the limiting plate 567 is provided with a guide groove 568, the movable shaft 562 slides along the inner wall of the guide groove 568, the rear end of the volleyball push block 561 extends into the launching tube 51, the rear ends of the limiting block 566 and the limiting plate 567 are fixedly connected to the launching tube 51, and the bottom end of the connecting tube 564 is fixedly connected to the connecting rod 58.

[0036] The guide groove 1 555 and the guide groove 2 568 have the same shape, and the left sides of the guide groove 1 555 and the guide groove 2 568 are inclined outward from right to left, so that the movable shaft 2 5516 moves to the left along the movable shaft 1 562 along the guide groove 1 555 and the guide groove 2 568 respectively. When sliding to the left end of the guide groove, it moves outward along the left end of the guide groove, thereby driving the push block assembly 551 and the volleyball push block 561 to move outward.

[0037] See also Fig.10 Slots 5911 are provided on both the front and rear sides of the push plate 591 to prevent the push plate 591 from being blocked by the volleyball push block 561 when it is pushed to the right.

[0038] In summary, when in use, the device is first placed in a desired plane position, and the height of the volleyball launcher 5 is adjusted by adjusting the height of the lifting frame 1. The angle of the launch tube 51 is adjusted by controlling the extension and retraction of the electric push rod 54. When the launch tube 51 rotates, the rotating connecting frame 52 rotates along the support ring 53 to adjust the launch angle of the volleyball. When adjusting the strength of the spike launch, the motor 5974 is controlled to generate power to drive the worm 5973 to rotate, and the rotation of the worm 5973 drives the worm wheel 5972 to rotate, and the worm wheel 5972 rotates. The rotation of the screw 595 drives the screw 595 to rotate. The rotation of the screw 595 drives the movable support ring 593 to move horizontally through the threaded fit between the screw 595 and the movable support ring 593. The movable support ring 593 slides along the outer wall of the movable rod 592. The launching force of the launch spring 594 is adjusted by the movement of the movable support ring 593, and then the launching force of the volleyball is adjusted. Since the worm gear 5972 cannot drive the worm 5973 to rotate, the movable support ring 593 has a good stability effect after adjustment, so that the movable support ring 593 will not be squeezed by the launch spring 594 to move;

[0039] The volleyball to be launched is placed in the ball loading frame 3, and the volleyball is lifted to the ball outlet 4 by the lifting frame 1, and after passing through the support ring 53 and the rotating connecting frame 52, it enters the launching tube 51. At this time, the volleyball is located between the push plate 591 and the volleyball push block 561, and the volleyball is limited to prevent the volleyball from falling out of the launching tube 51. The electric push rod 2 510 is controlled to drive the connecting tube 1 553 to move left, and the connecting tube 1 553 drives the volleyball limiting mechanism 1 56 and the connecting tube 2 564 of the volleyball limiting mechanism 2 57 to move left synchronously through the connecting rod 58. The connecting tube 1 553 drives the push block assembly 551 to move left through the light rod 1 552, and the push block assembly 551 pushes the push plate 591 to move left, and the push plate 591 squeezes the launching spring 594 to move left, and the push plate 591 drives the movable rod 592 to move left. When the connecting tube 2 564 moves left The volleyball push block 561 is driven to move leftward by the light rod 2 563, and the volleyball push block 561 pushes the volleyball to move leftward, so that the volleyball moves leftward along the push plate 591. Since the left sides of the guide slot 1 555 and the guide slot 2 568 are inclined outward from right to left, the movable shaft 2 5516 moves leftward along the movable shaft 1 562 along the guide slot 1 555 and the guide slot 2 568 respectively, and when it slides to the left end of the guide slot, it moves outward along the left end of the guide slot, thereby driving the push block assembly 551 and the volleyball push block 561 to move outward. The push block assembly 551 moves outward to disconnect the support for the push plate 591, and the volleyball push block 561 moves outward to prevent the launch of the volleyball from being blocked. The launch spring 594 generates elastic potential energy to push the push plate 591 out, and the push plate 591 pushes the volleyball in the launch tube 51 to launch, thereby completing the launch of the volleyball spike.

[0040] When the push plate 591 is reset, the electric push rod 2 510 is controlled to extend, and the electric push rod 2 510 pushes the connecting pipe 1 553 to move right, so that the push block assembly 551 and the volleyball push block 561 move right. When the push block assembly 551 passes the push plate 591, since the top surface of the block 5511 tilts downward from left to right, the block 5511 squeezes the push plate 591 downward when it moves to the right, and the block 5511 drives the vertical rod 5512 and the support plate 5514 to squeeze the reset spring 5515 downward, so that the block 5511 contracts. After the block 5511 moves to the right side of the push plate 591, the reset spring 5515 generates elastic potential energy to push the block 5511, the vertical rod 5512 and the support plate 5514 to move upward, so that the block 511 is reset, and the next volleyball spike can be launched.

[0041] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0042] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
