Abstract
The invention is related to the structure of an adhesive dispenser that is composed of an outer tube with a push rod and a handle. The apparatus uses a certain number of elastic elements to make relative displacement between push rod and outer tube, while it uses the locking end of the push rod and cotter groove to perform functions like locating, acceleration and stepwise movement, which makes easy operation for the users. Moreover, in the apparatus the outer tube can be equipped with an inner tube. So the spacing between inner tube and outer tube provides a mechanism that the sealant and adhesive filled in-between the inner and outer tube will flow out and mix under the motion of the push rod. This mechanism will not only facilitate sealing, adhesion and hardening prevention, but will also provide reusability.
Claims8
A structure of adhesive dispenser, comprising
- an outer tube, having a filling head at an end thereof, at an axial center of said filling head being a passing hole, surrounding the passing hole being a through hole, the outer tube also having a holding section protruding from an exterior at another end thereof,
- a push rod, having a rod with a plurality of toothed grooves on one side along the axis thereof, installed inside the outer tube;
- a specified number of elastic elements, having two ends attached respectively to the outer tube and the push rod, and capable of pulling the push rod to move by means of their elasticity;
- a handle, having two different protruded locking ends at one end thereof, the handle being movably fitted onto the outer tube, the locking ends matching the toothed grooves on the push rod, thereby the handle can be controlled to engage different locking ends with different toothed grooves, to set the push rod in position, or produce stepped movement and increase its acting force.
