Description

Gear box shell with reinforced structure and toy launcher Technical Field The utility model relates to the technical field of shooting toys, in particular to a gear box shell with reinforced structure and a toy launcher. Background Toy guns are a popular toy within the toy industry. The gear box of the toy gun is the core transmission part. The gear box is not only used for accommodating and supporting the mechanical components of the internal circulation firing of the toy gun, but also needs to bear larger mechanical stress caused by high-strength use of an upgrade spring, a high-speed motor, a pneumatic system and the like. Therefore, the gearbox housing must have extremely high mechanical strength. The existing toy gun gear box shell is usually made of common aluminum alloy, zinc alloy or engineering plastic, has limited mechanical strength, and is easy to crack or deform under high-load working conditions. Furthermore, existing housing designs are typically optimized for a single model only, lack suitability for different systems (e.g., pneumatic, electric hybrid) or upgrade components, and are less versatile. Disclosure of utility model In view of the above, the present utility model provides a gear case housing and toy launcher with reinforced structure, which aims to solve or at least improve the above problems to some extent. In order to solve the problems, the technical scheme is that the gearbox shell comprises a first shell and a second shell which are buckled with each other in the radial direction, the first shell and the second shell jointly define a containing cavity for containing a piston, a gear and a gearbox, the first shell and the second shell comprise a first part and a second part which are connected with each other in the axial direction, a third part which is positioned below the first part and the second part and is respectively connected with the first part and the second part, the axial direction is perpendicular to the radial direction, the second part is provided with a transmitting end which is away from the first part and is cylindrical, the transmitting end is limited with a transmitting hole which axially penetrates through the shell, the shell further comprises a reinforcing rib which extends along the axial direction, the reinforcing rib is connected with the upper circumferential surface and the lower circumferential surface of the transmitting end, and the reinforcing rib and the transmitting end are integrally formed. In some embodiments, the first housing is provided with an AOE inspection window radially extending through the first housing for viewing and adjusting contact between the gear and the piston. In some embodiments, the second housing is provided with at least one pre-load inspection window extending radially through the second housing for monitoring transmission cycling and piston operation. In some embodiments, the AOE inspection window is located at the junction of the second and third portions and extends in an axial direction. In some embodiments, the at least one pre-tensioned inspection window is located at the junction of the second and third portions and is in turn axially aligned. In some embodiments, the third portion is provided with alignment bolt holes for aligning the gearbox, and the alignment bolt holes are located at the reinforcing bars of the third portion. In some embodiments, the third portion bottom is provided with an adjustment bolt hole collectively defined by the first and second housings for mounting a trigger pretension adjustment screw.
