DETAILED DESCRIPTION

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

[0020] Reference Figure 1 , Figure 2As shown, the utility model discloses a gyro launching toy pen, which comprises a pen body consisting of a pen head 11 and a pen shell 12 and a pen core 14 arranged in the pen body, and has the writing function of a traditional pen.

[0021] A gyro launching mechanism is arranged on the pen housing 12, and the gyro launching mechanism comprises a support 13, a lower limit seat 42 arranged on the support 13, and a fixed seat 2 located above the lower limit seat 42. A button hole is opened on the side wall of the fixed seat 2, wherein the fixed seat 2 is composed of a symmetrical front shell 23 and a rear shell 24, and the button hole is located between the front shell 23 and the rear shell 24. A release button 21 is arranged in the button hole, and an upper limit seat 41 located above the lower limit seat 42 is arranged in the fixed seat 2, and a cavity 45 for accommodating the release button 21 to be inserted is arranged on the lower side of the upper limit seat 41, and an outer ratchet 43 is arranged at the central opening of the upper limit seat 41, and the outer ratchet 43 is composed of a plurality of grooves extending in the same direction around the central hole, and the grooves are divided into two groups, inner and outer, which fall into two concentric circles of different sizes respectively.

[0022] Reference Figure 3 , Figure 4 and Figure 5 As shown, a rotating shaft 5 and a torsion spring 6 surrounding the rotating shaft 5 are sequentially arranged at the central opening of the lower limit seat 42. One end of the torsion spring 6 is fixed on the rotating shaft 5, and the other end is connected to the pin 44 on the lower limit seat 42. The bottom of the rotating shaft 5 has an arc surface, which is preferably a hemispherical surface in this embodiment. The top end of the rotating shaft 5 is provided with an inner ratchet 51 inserted into the outer ratchet 43. The inner ratchet 51 is formed by two half-cut wedging surfaces at the top end of the circular shaft, and the two wedging surfaces form an angle α. The outer ratchet 43 and the inner ratchet 51 are respectively adapted to the outer ratchet 31 and the inner ratchet 32 ​​concentrically arranged on the main shaft of the gyroscope 3. The structure of the gyroscope 3 is as shown in FIG. Figure 6 As shown, the outer pawl 31 is composed of a plurality of fan blades extending in the same direction around the central axis, and the fan blades are divided into two groups, inner and outer, respectively falling into two concentric circles of different sizes, and the fan blades correspond to the grooves one by one, and the inner pawl 32 is formed by two half-cut wedging surfaces at the top of the circular shaft, and the two wedging surfaces are at an angle of β, wherein α=β. After the gyroscope 3 is inserted into the fixed seat 2, the wedging surfaces of the outer ratchet 43 and the inner pawl 32 are tightly attached to form an engagement, and the fan blade of the outer pawl 31 is inserted into the groove. After the gyroscope 3 is inserted, it is rotated a small angle, and the slight deformation of the fan blades will cause the outer pawl 31 to engage with the outer ratchet 43, and the gyroscope 3 will not fall off even if the pen body is turned upside down.

[0023] The release button 21 has an inclined surface 22 at the rear end, and a return spring 7 is arranged between the release button 21 and the fixed seat 2 or the upper limit seat 41. The arc surface of the rotating shaft 5 abuts against the inclined surface 22 of the release button 21. When the hemispherical surface of the rotating shaft 5 slides along the inclined surface 22, the horizontal movement of the release button 21 can be converted into the vertical movement of the rotating shaft 5.

[0024] The working principle of the gyro launching toy pen of the utility model is described below.

[0025] The torsion spring 6 of the utility model constitutes the energy storage mechanism of the gyroscope 3, and the release button 21 constitutes the release mechanism of the gyroscope 3. The gyroscope 3 is installed by meshing the outer ratchet 43 of the upper limit seat 41 and the inner ratchet 51 of the rotating shaft 5 with the gyroscope 3 correspondingly provided with the outer pawl 31 and the inner pawl 32.

[0026] When storing energy, the gyroscope 3 is first embedded in the upper limit seat 41. At this time, the outer pawl 31 and the inner pawl 32 on the inner shaft of the gyroscope 3 abut against the outer ratchet 43 on the upper limit seat 41 and the inner ratchet 51 on the rotating shaft 5 respectively. At this time, both hands hold the gyroscope 3 and the fixed seat 2 respectively to rotate, so that the gyroscope 3 rotates around the upper limit seat 41 or the upper limit seat 41 rotates around the gyroscope 3. At this time, the gyroscope 3 drives the inner ratchet 51 to rotate through the inner pawl 32, and then drives the rotating shaft 5 to rotate. The torsion spring 6 is driven to twist and store energy, and the outer ratchet 43 is stuck in the outer pawl 31, so that the gyroscope 3 cannot be reversed under the action of the torsion spring 6, thereby completing the energy storage of the gyroscope 3.

[0027] When the gyroscope 3 is to be launched, the release button 21 is pressed, and the release button 21 drives the wedge-shaped surface 22 to push the arc surface of the rotating shaft 5, thereby converting the horizontal movement of the release button 21 relative to the fixed seat 2 into the vertical movement of the rotating shaft 5 relative to the fixed seat 2. When the rotating shaft 5 moves downward, it pushes the gyroscope 3, so that its outer pawl 31 is separated from the outer ratchet 43, so that the gyroscope 3 rotates at a high speed under the action of the torsion spring 6 and separates from the upper limit seat 41 and the fixed seat 2 at the same time, completing the launch, and the release button 21 is reset under the action of the reset spring 7.

[0028] The lower limit seat 42 of the utility model is plugged with the upper limit seat 41. A plurality of positioning posts can be arranged on the lower limit seat 42, and the upper limit seat 41 is provided with corresponding positioning holes for the positioning posts to be inserted. Alternatively, a plurality of positioning holes can be arranged on the lower limit seat 42, and the upper limit seat 41 is provided with corresponding positioning posts to be inserted into the positioning holes.

[0029] Compared with the Chinese patent "A gyro toy pen", the utility model uses the outer pawl 31 and the inner pawl 32 of the gyro 3 to quickly and firmly insert the gyro 3 into the upper limit seat 41, without setting a rotating base, and the gyro 3 will not fall off when the pen body is turned over; the gyro 3 is energy-stored by the torsion spring 6 on the lower limit seat 42, rather than by the sliding drive member-rotating mechanism-rotating base; the gyro 3 is released by pushing the rotating shaft 5 through the inclined surface 22 at the tail end of the release button 21, instead of the inverted pen body falling off by the gyro's own gravity. The product has fewer parts and components and a simpler structure, which reduces costs on the one hand and reduces the failure rate on the other hand, thereby increasing reliability and improving playability.

[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.
