Abstract

This new utility model relates to quick-dismantling structure of gearbox on one peashooter, which belongs to mechanic category. This structure consists of lower body, upper body and insertion pin. Run-through hole is arranged on lower body, upon which is combined with upper body. Insertion hole is arranged on the upper body in line with the position of the run-through hole and one insertion pin is provided in insertion hole and run-through hole. Claws are provided at the upper body to clasp with camshaft. With insertion pin in conjunction with clasping device of claw and camshaft, lower body can be fastened tightly with upper body. Besides this, when disassembling the gearbox, only disengagement of the insertion pin out of insertion hole and run-through hole can achieve quick-separation of upper and lower bodies for users to do replacement and repair. Advantages: convenient assembly and disassembly; less time of consumption, easy for repair, strong practicality.

Description

The gear-box quick-disassembly structure of peashooter

Technical field

The utility model relates to mechanical, particularly a kind of gear-box quick-disassembly structure of peashooter.

Background technology

As shown in Figure 1, the gear box A of the general peashooter of using always, combining between its lower box A1 and upper box A2, be to be arranged between jack A5, A6 and perforation through the first pin A3 and the second pin A4, if when this gear box A is done separating action, need the first pin A3 and the second pin A4 are extracted respectively when jack A5 and the perforation A6, it causes the user when replacing with casing A2 or carrying out the maintenance of gear box A, need expend the long time, need be improved.

The utility model content

The purpose of this utility model is to provide a kind of gear-box quick-disassembly structure of peashooter, has solved problems such as the gear-box dismounting trouble of peashooter commonly used, the length that expends time in.

The technical solution of the utility model is: comprise lower box, upper box and pin, be provided with perforation in lower box, be combined with upper box on this lower box, upper box is provided with jack and corresponding to the position of perforation, and is equipped with a pin in this jack and the perforation; Upper box is provided with the hook part and is sticked in lower box and is provided with protruding axle, this gear-box cooperates the clamping close device of hook part and protruding institute's shape by pin, make between lower box and upper box and be able to fastening the combination, this clamping close device can be made as sliding push type device, bar button device and the relevant device of signing an undertaking and closing; When gear-box is done decomposition, pin is broken away from jack and perforation, can separate upper box and lower box fast, so that doing, the user changes and maintenance.

Advantage of the present utility model is: the dismounting facility, and it is few to expend time in, and convenient for maintaining is practical.
