Description

Glue gun structure

The present invention relates to the technical field related to electric hand tools, and in particular to a glue gun structure.

According to the rules, doors and windows that are used as movable stops need to be equipped with sealing strips on the frame. The sealing strips can play the role of waterproofing, dustproof, shock absorption, buffering, and reducing or eliminating the vibration noise of objects. The installation of sealing strips is mostly done manually by using a hand hammer or a rolling tool with a roller to press the strip into the strip groove. In addition to being firm and not easy to fall off, the installation of sealing strips also requires that its appearance is smooth and flat. No scratches or damage.

The problems that the above-mentioned strip installation process needs to face include: Low installation efficiency: Manual installation of sealing strips requires a lot of time and effort, especially in the case of large-scale installation, which may lead to reduced work efficiency.

High labor intensity: Installing the sealing strip requires the use of a hammer or roller pressing tool to press the strip, which requires a certain amount of physical strength and labor intensity, especially in long-term continuous operations.

Improper installation: Due to manual installation factors, uneven installation or incomplete compaction may occur. This may lead to poor sealing or falling off during use.

In view of this, how to provide operators with suitable hand tools to improve installation efficiency, reduce operator labor, and ensure secure installation, etc., the existing glue pressing tools really need to be improved.

In view of the above-mentioned problems and deficiencies of the prior art, one of the main purposes of the present invention is to provide a glue gun structure to overcome the deficiencies of the prior art through structural innovation.

According to the above-mentioned purpose of the present invention, the present invention discloses a kind of pressure gun structure, including a housing, a connecting sleeve, a spring, a top rod, a limit shaft sleeve, at least one limit piece, a clutch upper seat, a plurality of balls, a clutch lower seat, and a driving mechanism. The connecting sleeve is assembled in the housing and has a hierarchical shaft hole. The spring is accommodated in the hierarchical shaft hole. The top rod has one end abutting against the spring and the other end protruding from the connecting sleeve. The limit shaft sleeve is serially connected to the connecting sleeve and has a through hole and at least one limit groove. At least one limit piece has one end inserted in the limit groove. The clutch upper seat has one end extending through a through hole to abut against the top rod and constrain the limiter, and the other end is provided with multiple ball grooves to accommodate each ball. The clutch lower seat abuts against each ball assembly housing. The driving mechanism is connected in series with the clutch lower seat to provide a power. Through the composition of the above components, it is convenient for the user to connect a pressing head in series with the top rod to apply an impact force to the preset rubber strip, and quickly press the rubber strip into the rubber strip groove.

Therefore, the above is an introduction to the various components and assembly methods of the glue gun structure provided by the present invention in a preferred embodiment. The operating features of the embodiment of the present invention are introduced as follows.

During implementation, the power source 71 (driving gear 712) is activated, driving the planetary gear set 76 (each planetary gear 763) to activate, so that each planetary gear 763 rotates along the inner gear shaft hole 751 of the engaged inner gear sleeve 75, and the wheel seat 761 of the movable pivot rotates at the same time.

When the wheel seat 761 is pulled and rotated, the sleeve disc 74 connected in series is moved at the same time, and the sleeve disc 74 also moves the clutch lower seat 60 connected to the sleeve and rotates at the same speed.

During the self-spinning process of the clutch lower seat 60, the balls 50 partially assembled in each ball hole 61 are driven to move along the ball groove 43 and are replaced in different ball grooves 43. During the displacement process of each ball 50 (when not in the ball groove 43), the clutch upper seat 40 is pushed by each ball 50 to move along the through hole 32 of the limit sleeve 30 toward the top rod 16. During the process, the rod 41 of the clutch upper seat 40 pushes the top rod 16 to move along the step shaft hole 21 and compresses the spring 14.

When each ball 50 is displaced and moved into each ball groove 43, the spring 14 pushes the top rod 16 and the rod 41 of the clutch upper seat 40 back synchronously, and the top rod 16 repeatedly forms a reciprocating axial motion.

Through the above-mentioned movement pattern, the top rod 16 can be assembled with a preset shape of the press joint A according to the needs, and then the press joint A is used to press against the rubber strip (not shown in the figure), so that the press joint A reciprocates to press against the rubber strip, which is convenient for the user to assemble the rubber strip.

The above description is only the preferred implementation mode of the present invention, which is intended to clarify the features of the present invention, and is not intended to limit the scope of the embodiments of the present invention. Equal changes made by ordinary technicians in the technical field based on the present invention, as well as changes familiar to technicians in the technical field, should still fall within the scope of the present invention.
