Flap cylinder launching tube

Abstract

According to the crackle cylinder launching tube, an opening of a launching tube filling end with the thickness not larger than 0.5 mm expands outwards, the launching tube filling end with the thickness larger than 0.5 mm is a groove inclining from inside to outside, and an opening of an emitting end of the launching tube shrinks inwards; the improvement schemes of the filling end and the emitting end of the crackle cylinder emitting tube can be independently applied. The diameter of the projectile body cut by vertically pressing tuberous roots, tubers, melons and fruits and the like through the launching tube is larger than the inner diameter of the launching tube body, due to the blocking and extruding effects of the launching tube on the projectile body, the air tightness and friction force between the launching tube and the projectile body are improved, the probability of successful launching is improved, and the playability of the crackle cylinder is improved.

Description

Technical Field

[0001] The present invention relates to the field of toys, in particular to a launching tube of a crackling tube toy Background Art

[0002] The crackle tube consists of a launch tube and a push rod. The part of the push rod that can enter the launch tube is slightly shorter than the launch tube. Before the first launch, fill the two ends of the launch tube with objects (projectiles), and use the push rod to push the projectile from one end of the launch tube (the loading end). The push rod pushes the projectile, and the air between the two projectiles is compressed. When the air pressure can overcome the friction of the projectile at the other end (the ejection end), the projectile is ejected with a "crackling" sound. For subsequent launches, you only need to load at the loading end.

[0003] Traditional crackle guns use bamboo tubes as launch tubes, and use granular fruits of plants or wet paper balls for firing. Now there are industrialized versions of crackle guns, which usually use aluminum alloy tubes as launch tubes and fire rubber soft bullets. Due to the thick tube wall, these two types of crackle guns need to insert the projectile into the tube. There is also a traditional toy called orange peel gun, which is also a crackle gun, using a pen tube or ballpoint pen core tube as the launch tube. The wall of the orange peel gun barrel is thin, and the orange peel is soft and easy to cut. Press the orange peel vertically with the launch tube to cut the orange peel and put it into the tube.

[0004] Whether the crackle tube can be successfully launched and the size of the sound when launched are related to the friction between the projectile and the wall of the launch tube and the airtightness. Unripe granular fruits, wet paper balls, rubber soft eggs and the launch tube are interference fits, which can increase friction and airtightness. The orange peel projectile used in the orange peel gun is a transition fit with the launch tube, which is insufficient in airtightness and friction, but the orange peel can exude a liquid containing tannic acid to make up for the problem of insufficient airtightness and friction. Despite this, the orange peel gun has a high probability of not being able to be successfully launched. Using the launch tube of the thin-walled crackle tube to vertically press the sliced ​​roots, tubers, fruits and other items to obtain the projectile, there is a greater probability of failure in the launch. If the problem of insufficient airtightness and friction is solved, the probability of successful launch of roots, tubers, fruits and other items as projectiles can be increased, and the playability of the crackle tube can be improved. For example, after eating watermelon, the watermelon peel can still be used to play with the crackle tube. In addition, roots, tubers, fruits and other items are easy to degrade, and after being launched, they will not pollute the environment even if they are not recycled. Summary of the invention

[0005] In order to solve the problems in the background technology, the present invention proposes a crackling tube launch tube, which improves the air tightness and friction between the launch tube and the projectile body. The technical solution of the present invention is as follows:

[0006] The opening of the loading end of the launch tube with a thickness not exceeding 0.5 mm expands outward, and the loading end of the launch tube with a thickness exceeding 0.5 mm is a groove inclined from the inside to the outside, and the opening of the launch tube exit end shrinks inward; or for the launch tube with a thickness not exceeding 0.5 mm, only the opening of the loading end is expanded outward, and for the launch tube with a thickness exceeding 0.5 mm, only the loading end is a groove inclined from the inside to the outside; or only the opening of the launch tube exit end shrinks inward.

[0007] When the loading end opening is expanded and there is a groove, the inner diameter of the tube mouth is 1.05 to 1.30 times the inner diameter of the launch tube body, and when the exit end opening is contracted, the inner diameter of the tube mouth is 0.50 to 0.95 times the inner diameter of the launch tube body.

[0008] When the inner diameter of the tube opening at the loading end of the crackle tube is larger than the inner diameter of the tube body, the diameter of the projectile cut by vertically pressing the root, tuber, fruit, etc. with the launch tube is larger than the inner diameter of the launch tube body. When the push rod pushes the projectile in the launch tube, the launch tube squeezes the projectile toward the center, improving the airtightness and friction between the launch tube and the projectile.

[0009] When the inner diameter of the exit port of the crackle tube launch tube is smaller than the inner diameter of the launch tube body, the projectile will be blocked in the process of leaving the launch tube and will be squeezed toward the center, which improves the air tightness and friction between the launch tube and the projectile.

[0010] Since the present invention improves the air tightness and friction between the launching tube and the projectile, the beneficial effects brought about are: the probability of successful launching of the crackling tube when using roots, tubers, melons and fruits as the projectile is improved, and the playability of the crackling tube is improved; in addition, the crackling tube can use roots, tubers, melons and fruits as the projectile, and is environmentally friendly at the same time.
