Description

FIELD OF THE INVENTION

The present utility patent relates to the toy technology, and more particularly, to an ejection toy.

BACKGROUND OF THE INVENTION

Ejection toys are common toys that shoot at objects through elastic bullets for entertainment. In order to make them greater fun, in some ejection toys, a string is set between the bullet and ejection toy, which can not only help to draw back the bullet through the string after the bullet is shot, but also control the launching distance of the bullet relying on the length of the string, so as to improve the safety of the ejection toys. For example, a string launcher —China Patent Publication No.: CN217246756U, which is set with a reel entangled with a piece of string, is just one of them. Because the reel is entangled with a piece of string, the reel needs to be pulled through the string to rotate when the string launcher is ready for launch, affecting the launching speed of the string launcher. In addition, during launching of the string, when the bullet encounters a barrier, the reel rotates continuously due to inertia under an incomplete launching, which is liable to make part of the string fall off the reel and be jammed in the launch tube or the reel slot, causing knotting or seizing of the string, and then failing to retract the string smoothly by the string launcher; therefore, an improvement is needed.

The ejection locking mechanism 600 can drive the string retracting wheel 501 and friction wheel 502 to approach each other to hold the string 400 under its own restoring force. The driving component 700 drives the string retracting wheel 501, and at the same time, the string retracting wheel 501 drives the friction wheel 502 under a friction force, making the string 400 held between the string retracting wheel 501 and friction wheel 502 move towards the container a under the friction force, and thus achieving string retracting.

The fourth sloping surface at one end of a rocker arm 614 contacts with the fifth sloping surface on the linkage 603, so the linkage 603 can expand the angle between the two rocker arms 614 during moving. The rocker arms 614 can help to separate the gear 703 from the worm 702 during rotation while driving the string retracting wheel 501 and friction wheel 502 to release the string 400; At the same time, the sliding of the linkage 603 makes the propping part 605 of the linkage 603 insert into the butt-joint slot i along the first sloping surface, thereby driving the sliding buckle 612 to move downwards, separating the sliding buckle 612 from the snap-fit slot e of the bullet 300, unlocking the bullet 300 and allowing launching of the bullet 300 by the first elastic member 202. When the user releases the trigger 602, the linkage 603 can reset under the restoring force of the second elastic member 604, the sliding buckle 612 can reset under the restoring force of the third elastic member 613, and the rocker arms 614 can reset under the restoring force of the fourth elastic member 615, making the string retracting wheel 501 and friction wheel 502 hold the string 400. When retracting the string and pressing the control switch 705 to control the motor 701, the motor shaft can drive the worm 702 as well as the gear 703 to rotate. The gear 703 drives the string retracting wheel 501 through the second rotating shaft 601, and the string retracting wheel 501 drives the friction wheel 502 through friction while making the string 400 be retracted into the container a.

Preferably, in order to avoid entangling of the string 400 around the string retracting wheel 501 and/or friction wheel 502 during string retracting in the container a, as shown in FIG. 5, the container a is provided with separator parts 102. The separator parts 102 have openings connecting to the locking track (d); The separators are used to separate the string 400 in the container a from the string retracting wheel 501 and the string 400 in the container a from the friction wheel 502.
