Summary of the invention
Technical matters to be solved by this invention is to provide the high and water rocket launching device that experiment effect is good of a kind of security.
In order to solve the problem, the technical solution adopted in the present invention is: this water rocket launching device includes expelling plate, and described expelling plate is hinged on seat board by hinge, and described seat board is provided with the limiting plate that described expelling plate rotates around described hinge; Described expelling plate is equipped with one and has the charging connector being set with conical seal ring; Described expelling plate is provided with the location-plate of arc in described charging connector side, and two movable depression bars are at least housed between described location-plate and described charging connector, is provided with ejector in described charging connector opposite side; Described ejector has the ejection plate be hinged on described expelling plate, and having in described ejection plate clamps the arc-shaped slot of described movable depression bar, and described ejection plate is crossed wire rope and is connected with control brake lever.
In technique scheme, technical scheme can also be more specifically: described arc-shaped slot is located at the both sides of described ejection plate, described ejection plate be provided with above described arc-shaped slot be connected with described wire rope draw pin; Described location-plate is positioned at the nearly described hinge side of described expelling plate.
Further: described limiting plate is provided with deep-slotted chip breaker, described expelling plate is provided with the screw rod through this deep-slotted chip breaker, described screw rod is provided with gland nut.
Further: described charging connector is connected with inflator by tracheae.
Further: described conical seal ring is rubber parts.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, owing to being provided with location-plate and movable depression bar in the side of expelling plate charging connector, ejector is provided with at the opposite side of charging connector, ejector has the ejection plate be hinged on expelling plate, and ejection plate is provided with the arc-shaped slot clamping movable depression bar; First the air intake opening of water rocket is tipped upside down on the conical seal ring of charging connector, movable depression bar is pressed in the collar flange outside water receiving rocket air intake opening, then ejection plate is upwards overturn make the arc-shaped slot of its both sides and the clamping of two movable depression bar phases; So just avoid water rocket to come off from launcher, security is high; 2, due to the adjustable angle of expelling plate, during transmitting, ejection plate pulled open rapidly by controlling brake lever, water rocket can launch away instantaneously, and directivity is clear and definite, and experiment effect is better; 3, practicality, this device is drawn materials easily, and make simple, effect is fine, is applicable to student and makes, improve manipulative ability.
