The catapulted object is piled in the catapulting cylinder, a spring is arranged at the tail end of the catapulting cylinder, a cylinder cover is arranged at an outlet end of the catapulting cylinder, the cylinder cover is hinged on the catapulting cylinder, the catapulted object is pressed into the catapulting cylinder and compresses the spring, a locking groove is formed in the catapulted object, and a locking pin is inwards inserted in the locking groove from the side wall of the catapulting cylinder. One end of the locking pin is inserted into the locking groove, a first air cylinder which is arranged vertically is arranged outside the catapulting cylinder close to the hinged point of the cylinder cover, a T-shaped pressing rod is drawn from a piston of the first air cylinder, a reset spring is arranged between the T-shaped pressing rod and a first air cylinder body, and pressing blocks are arranged at the outer circumference of the hinged point of the cylinder cover in an extending mode. A second air cylinder and a third air cylinder are respectively arranged on two sides of the outer end of the locking pin, a connection rod is connected between a piston of the second air cylinder and a piston of the third air cylinder, the connection rod is connected with the locking pin, and two air chambers of the first air cylinder are respectively and correspondingly connected with two air chambers of the second air cylinder and two air chambers of the third air cylinder.

Description

A kind of toy catapult

Technical field:

The utility model relates to a kind of toy catapult.

Background technology:

On market, toy catapult is of a great variety, peashooter, bead ejector etc. are arranged, these ejectors are all to put into by projectile in the ejection guns of ejector simply, the ejection guns milli unhinderedly communicates with the external world, this ejector easily occurs not met by the unexpected danger of penetrating of projectile the requirement that the head of a family places above the other things safely to toy catapult when child plays.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, to provide a kind of security very high toy catapult.

goal of the invention of the present utility model can realize by following technical scheme: a kind of toy catapult, include ejection guns and by projectile, filled in ejection guns by projectile, end at ejection guns is provided with spring, the port of export is provided with cover, cover is hinged on ejection guns, compressed into ejection guns and Compress Spring by projectile, be provided with locked groove by projectile, from outer inwardly the reeve through the ejection guns sidewall, lock pin is arranged, one end of lock pin injects locked groove, be provided with the first cylinder of vertical setting near cover pin joint place outside ejection guns, draw T shape depression bar from the piston of the first cylinder, be provided with back-moving spring between T shape depression bar and the first cylinder block, be extended with briquetting on the excircle of cover pin joint, be respectively equipped with the second cylinder and the 3rd cylinder in the both sides, outer end of lock pin, connect connecting rod between the second cylinder piston and the 3rd cylinder piston, connecting rod is connected with lock pin, the 2 air chambers of the first cylinder is corresponding respectively to be connected with the 2 air chambers of the second cylinder with the 3rd cylinder.

After adopting the technical program, compared with prior art, the technical program has the following advantages: by in the ejection guns exit, cover being set, order about the lock pin release when being rotated by cover, order is to being penetrated by projectile, as long as cover is not opened, lock pin all can guarantee to pin by projectile, thus the security that has improved toy catapult.

Description of drawings:

Fig. 1 is that the cover of the utility model toy catapult is blocked the ejection guns structure chart in when outlet;

Fig. 2 is the structure chart when being penetrated by the projectile release after the cover rotating opening of the utility model toy catapult.

The specific embodiment:

Below in conjunction with accompanying drawing, present technique is described further.

the toy catapult of the present embodiment includes ejection guns 1 and by projectile 2, filled in ejection guns 1 by projectile 2, end at ejection guns 1 is provided with spring 3, the port of export is provided with cover 4, cover 4 is hinged on ejection guns 1, compressed into ejection guns 1 and Compress Spring 3 by projectile 2, be provided with locked groove 5 by projectile 2, from outer inwardly the reeve through ejection guns 1 sidewall, lock pin 6 is arranged, one end of lock pin 6 injects locked groove 5, at outer the first cylinder 7 that is provided with vertical setting near cover 4 pin joint places of ejection guns 1, draw T shape depression bar 8 from the piston of the first cylinder 7, be provided with back-moving spring 9 between T shape depression bar 8 and the first cylinder block, be extended with briquetting 10 on the excircle of cover 4 pin joints, be respectively equipped with the second cylinder 11 and the 3rd cylinder 12 in the both sides, outer end of lock pin 6, connect connecting rod 13 between the second cylinder piston and the 3rd cylinder piston, connecting rod 13 is connected with lock pin 6, the 2 air chambers of the first cylinder 7 is corresponding respectively to be connected with the 2 air chambers of the second cylinder 11 and the 3rd cylinder 12.

Cover 4 rotating opening, this moment, briquetting 10 will press down T shape depression bar 8, the piston that makes the first cylinder 7 drive simultaneously the second cylinder 11 and the 3rd cylinder 12 moves up, thereby drive lock pin 6 and skid off ejection guns 1, the inner of lock pin 6 detaches locked groove 5, by projectile 2 releases, be subjected to spring 3 to promote to penetrate by projectile 2.Generally, in the situation that cover 4 is not opened, the first cylinder 7 is not have action, guarantees that the second cylinder 11 and the 3rd cylinder 12 can not move, and lock pin 6 keeps sticking in locked groove 5, thereby prevents by the unexpected ejaculation of projectile 2.

The above is only preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art, do not breaking away from technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore every content that does not break away from technical solutions of the utility model, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in protection domain of the present utility model.
