[0002] The new technologies currently developed around gyroscopes are all aimed at improving the main performance of gyroscopes, such as changes in rotation stability, rotation speed, and attack performance, so that children can get more fun from playing with toy gyroscopes.

[0003] There is a gyroscope launcher currently on the market, whose driving mechanism mainly includes a gear box and a rack. When loading the gun, the rack needs to be pulled backwards, and the gyroscope can be driven to rotate by the gear box. The trigger is pulled to release the top cover plate, and the gyroscope gear shaft is pushed forward by the fork to launch the gyroscope.

[0004] The above-mentioned gyro launcher mainly rotates the gyro by repeatedly pulling the rack / pull rope to convert the horizontal movement into the rotation of the gyro axis. When playing, the player usually holds the launcher with the left hand and pulls the rack / pull rope with the right hand. During the battle, the left hand is restricted and cannot be freed. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the prior art, the utility model provides a gyro toy launcher which can be worn on the wrist and can launch gyros, so that the left hand can be freed when playing against the opponent.

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Reference Figure 1 As shown, the utility model discloses a wristband type toy gyroscope launcher, comprising a dial 1 composed of a lower disc body 11 and an upper disc body 12, and a detachable strap 2. Figure 2 The figure shows the toy gyroscope launcher after the strap 2 is removed. The top of the upper plate body 12 is provided with a gyroscope cavity 21 for placing the gyroscope 5, which is used to load and clamp the gyroscope 5. The bottom of the gyroscope 5 launched by the present patent application is provided with a gyroscope shaft 51, a limit seat and a gyroscope gear in sequence, and the cross-section of the limit seat is a regular polygon. A driving mechanism for accelerating the gyroscope 5 and a release mechanism for pushing the gyroscope 5 away are respectively provided in the dial 1.

[0021] like Figure 3 As shown, the driving mechanism of the utility model includes a gear box 4 formed by a box bottom cover 41 and a box top cover 42 buckled together, and an acceleration gear set arranged in the gear box 4, wherein the acceleration gear set is composed of an input gear 43 fixedly arranged between the box bottom cover 41 and the box top cover 42, an output gear 44, and a double gear 45 movably arranged between the box bottom cover 41 and the box top cover 42, and the outer diameter of the input gear 43 is much larger than the output gear 44 and the double gear 45, and the double gear 45 has coaxial upper and lower layers of teeth, the lower layer of teeth meshes with the input gear 43, and the upper layer of teeth meshes with the output gear The output gear 44 is meshed with the gyroscope gear on the gyroscope shaft 51. A winding groove 47 and a mainspring are connected below the input gear 43. A pull rope 31 is wound around the winding groove 47, and a pull ring 3 is connected to the pull rope 31. When the pull ring 3 is pulled backward, the pull ring 3 pulls the input gear 43 to rotate through the pull rope 31, and the output gear 44 is accelerated through the input gear 43 and the double gear 45, and the gyroscope 5 is accelerated through the meshing of the output gear 44 and the gyroscope gear.

[0022] A top cover plate 22 that can move horizontally is arranged in the gyro chamber 21 of the utility model, a first return spring (not shown in the figure) is arranged between the top cover plate 22 and the lower disk body 11 or the upper disk body 12, a fork 23 for accommodating the gyro shaft 51 is arranged at the front end of the top cover plate 22, a hook 24 is arranged on the left or right side of the fork 23, the first return spring can be buckled on the hook at the top of the rear end of the top cover plate 22, and the gyro 5 is loaded by placing it into the top cover plate 22 and then pushing the gyro 5 backwards. After the gyro 5 is launched, the top cover plate 22 is reset under the action of the first return spring.

[0023] Reference Figure 4 , Figure 5 As shown, the release mechanism of the utility model includes a launch button 6 arranged in each half of the button groove on the lower plate body 11 and the upper plate body 12, and a tenon 61 corresponding to the hook 24 is arranged on the launch button 6. After the gyro 5 is loaded, the tenon 61 hooks the hook 24, and a second reset spring (not shown in the figure) is arranged between the bottom end of the launch button 6 and the gear box 4 for resetting after the launch button 6 is pressed down. After the gyro 5 is loaded, the tenon 61 hooks the hook 24 to limit the top cover plate 22. When the launch button 6 moves downward, the tenon 61 is separated from the hook 24 to release the top cover plate 22.

[0024] The working principle of the watch-type gyro toy launcher of the utility model is described below:

[0025] In the initial state, the gyro 5 to be launched is placed in the fork 23 of the top cover plate 22, and the top cover plate 22 is pushed backward to compress the first return spring until the hook 24 is hooked by the tenon 61. At this time, the gyro 5 is in the state of being ready to launch; when the pull ring 3 is quickly pulled backward, the gyro 5 is accelerated by the acceleration gear set, and the gyro 5 is in a high-speed rotation state; once the launch button 6 is pressed by hand, the tenon 61 on its top is disengaged from the hook 24, and the top cover plate 22 launches the gyro through the fork 23 under the action of the first return spring.

[0026] Compared with the existing gyroscope toy launchers, the utility model can be fixed on the left wrist through the strap 2, and the loading of the gyroscope, energy storage and launching are all completed by the other hand. During the battle, the left and right hands are freed, which is convenient for holding other toys. At the same time, the direction of the gyroscope cavity 21 can be adjusted by rotating the arm, which can more conveniently control the launching direction of the gyroscope. In addition, when not playing games, the launcher can be worn on the wrist and used as a toy watch.

[0027] Furthermore, the bottom cover 41 and the top cover 42 are provided with arc grooves 46 concentric with the input gear 43, and the shafts at both ends of the double gear 45 are located in the arc grooves 46, so that the double gear 45 can move circumferentially around the input gear 43 along the arc grooves 46. When the pull rope 31 is pulled through the pull ring 3, the winding groove 47 and the input gear 43 rotate forward and drive the mainspring to rotate and store energy, and the input gear 43 is accelerated through the double gear 45 and the output gear 44, and the output gear 44 is meshed with the torsion gear to accelerate. The gyroscope 5 is accelerated, and when the input gear 43 rotates, it moves along the arc groove 46 under the action of centrifugal force and separates from the input gear 43 and the output gear 44. When the pull ring 3 is released, the energy-storing mainspring automatically rotates in the reverse direction to recover the pull rope 31, thereby driving the input gear 43 to rotate in the reverse direction. When the pull rope 31 is pulled again, the double gear 45 that slides to the end of the arc groove 46 and is rebounded again meshes with the input gear 43 and the output gear 44, and the gyroscope 5 is accelerated again. The gyroscope 5 can be repeatedly accelerated by pulling the pull ring 3.

[0028] Furthermore, an elastic buckle piece 7 is provided in the fork 23. The elastic buckle piece 7 can be connected to the sword blade portion 2 and extend from the opening of the side wall of the top cover plate 22. It is used to adapt to the limit seat 52 set between the gyroscope shaft 51 and the gyroscope gear at the bottom of the gyroscope 5, and the loaded gyroscope 5 is fixed by the clamped limit seat 52 to prevent it from falling off.

[0029] The watch band 2 of the present invention can be arranged to be perpendicular or parallel to the top cover plate 22 to determine whether the gyroscope is launched horizontally or vertically.

[0030] The above embodiments are only illustrative of the principle and efficacy of the present invention, as well as some embodiments of its application. A person skilled in the art may make several modifications and improvements without departing from the inventive concept of the present invention, and all of these belong to the protection scope of the present invention.
