Description

Technical Field

[0001] The utility model relates to the technical field of glue spraying equipment, in particular to a glue spraying gun connecting rod mechanism. Background Art

[0002] A glue gun is a common handheld tool used to precisely apply glue, sealant or adhesive to a target surface. These applications include construction, decoration, auto repair, furniture manufacturing and other fields. In order to achieve efficient and precise application of glue, the design of the glue gun is crucial. The high friction generated at the contact point between the sliding connecting rod and the guide cylinder of the glue gun in the related art will not only reduce the smoothness of the operation, but also cause accelerated wear of the connecting rod mechanism, thereby affecting the service life and maintenance cost of the glue gun. Secondly, due to the lack of an effective buffering mechanism, the push plate may leak glue due to impact during movement, which will not only waste glue, but also may damage the structure of the glue gun. In addition, the push plate rebounding too quickly may also cause damage to the glue gun, affecting its stability and reliability. In view of this, it is necessary to improve the current glue gun connecting rod mechanism to solve the above problems;

[0003] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a glue gun connecting rod mechanism to solve the problem that the high friction generated at the contact part between the sliding connecting rod and the guide cylinder of the glue gun proposed in the above background technology not only reduces the smoothness of operation, but also causes accelerated wear of the connecting rod mechanism, thereby affecting the service life and maintenance cost of the glue gun. Secondly, due to the lack of an effective buffer mechanism, the push plate may leak glue due to collision during movement, which not only wastes glue, but also may damage the structure of the glue gun. In addition, the push plate rebounding too quickly may also cause damage to the glue gun, affecting its stability and reliability.

[0010] The beneficial effects of the utility model are:

[0011] Through this mechanism, when the operator pulls the trigger, the sliding link moves along the guide hole of the guide cylinder, thereby pushing the circular push plate forward. The guide cylinder is made of polyurethane material, which has good wear resistance and self-lubricating properties, so it can reduce friction during sliding, improve the service life of the link mechanism and the smoothness of operation.

[0012] Since one side of the sliding connecting rod is connected to the circular push plate through a nut, the stable movement of the push plate is ensured, and the first rubber gasket can provide good buffering to avoid glue leakage caused by friction between the push plate and the rubber barrel. The second rubber gasket on the side of the guide cylinder provides good buffering between the push plate and the guide cylinder to avoid damage to the glue gun caused by too fast rebound of the push plate.

[0019] Reference Figure 1-2 A glue gun connecting rod mechanism comprises a glue gun barrel 1, a sliding connecting rod 3, a limit block 5 and a trigger 14, a glue tube baffle 2 is fixedly installed on one side of the glue gun barrel 1, an arc bracket 101 is fixedly installed inside the glue gun barrel 1, a limit block 5 is fixedly installed inside the glue gun barrel 1, a guide cylinder 6 is fixedly installed inside the limit block 5, a guide hole is opened inside the guide cylinder 6, the guide cylinder 6 is made of polyurethane, a second rubber gasket 601 is fixedly installed on one side of the guide cylinder 6, the sliding connecting rod 3 passes through the guide hole of the guide cylinder 6, one side of the sliding connecting rod 3 is connected to a circular push plate 4 through a nut 402, and a first rubber gasket 401 is fixedly installed on one side of the circular push plate 4.

[0020] With this design, when the operator pulls the trigger 14, the sliding link 3 moves along the guide hole of the guide cylinder 6, thereby pushing the circular push plate 4 forward. The guide cylinder 6 is made of polyurethane material, which has good wear resistance and self-lubricating properties, so it can reduce friction during sliding, improve the service life of the connecting rod mechanism and the smoothness of operation.

[0021] Since one side of the sliding connecting rod 3 is connected to the circular push plate 4 through the nut 402, the stable movement of the push plate 4 is guaranteed, and the first rubber gasket 401 can provide good buffering, avoiding glue leakage caused by the friction between the push plate 4 and the glue cylinder. The second rubber gasket 601 on the side of the guide cylinder 6 provides a good buffer between the push plate 4 and the guide cylinder 6, avoiding damage to the glue gun caused by the push plate 4 rebounding too quickly.

[0023] Through this design, the arrangement of the inner bracket 7, the first spring stopper 8 and the second spring stopper 11 provides dual stopper and support for the sliding link 3, so that the sliding link 3 can always be kept in the correct position during operation without deviation or jamming. The elastic force of the first spring 9 and the second spring 12 further stabilizes the movement of the sliding link 3, so that it can push the circular push plate 4 more smoothly during use, achieve uniform gluing, and improve the accuracy and consistency of the gluing effect.

[0025] Through this design, the setting of the grip 15 enables the user to hold and control the glue gun more conveniently, and enhances the comfort and stability of use. The movable connection mode of the first pin 16 and the second pin 17 enables the trigger 14 to be flexibly operated. The user only needs to gently pull the trigger 14 to make the second pin 17 push the sliding sheet 10 to drive the sliding connecting rod 3, so as to achieve precise gluing operation, which not only improves the efficiency of gluing, but also reduces the user's operating fatigue, and increases the practicality of the product and the satisfaction of the user experience.

[0026] In this embodiment, when the operator pulls the trigger 14, the sliding link 3 moves along the guide hole of the guide cylinder 6, thereby pushing the circular push plate 4 forward.

[0027] Since one side of the sliding connecting rod 3 is connected to the circular push plate 4 through the nut 402, the stable movement of the push plate 4 is guaranteed, and the first rubber gasket 401 can provide good buffering, avoiding glue leakage caused by the friction between the push plate 4 and the glue cylinder. The second rubber gasket 601 on the side of the guide cylinder 6 provides a good buffer between the push plate 4 and the guide cylinder 6, avoiding damage to the glue gun caused by the push plate 4 rebounding too quickly.
