Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a novel glass glue gun. Background Art

[0002] Glass glue gun is a sealing and caulking glue tool, which is widely used in building decoration, electronic appliances, automobiles and automobile parts, ships and containers and other industries. Glass glue gun mainly includes barrel, push rod, trigger and other parts. The push rod is equipped with a rear buckle ring. Before use, press the rear buckle ring with your thumb and pull it back as far as possible. Put the glass glue head (the end with the mouth) first, so that the glue mouth part is exposed in front, and then put the whole glass glue tube in, relax the thumb part, and squeeze it. At present, many structural improvements on glass glue guns have been disclosed. For example, Chinese patent announcement No. CN214160347U discloses a glass glue gun, which specifically includes the following: a barrel, a push rod, a trigger, a gun body, a spring, a glue gun effort-saving propulsion device, and a propulsion piece. The characteristic is that the propulsion piece is composed of a metal block, a rubber pad, and a metal block stacked in sequence, and is installed on the push rod through a hole, a roller is arranged in the middle of the top of the trigger, bearings are respectively arranged on both sides of the trigger, and rubber sleeves are sleeved on the bearings. The springs are a coarse spring and a thin spring, and the coarse spring, the propulsion piece, and the thin spring are sequentially installed on the push rod; thus, the structure is reasonable and simple, and it can effectively reduce the friction between the trigger and other components, reduce the noise during use, and extend the service life of the glass glue gun.

[0003] The working principle of the above patented structure is similar to that of a traditional glass glue gun. By manually pressing the plate back and forth, the push rod is driven to move forward in one direction at a certain distance, thereby squeezing out glue from the glass glue cylinder. However, from actual application, we found that the above structure still has the following defects: glass glue will overflow from the mouth of the glass glue cylinder during a pause, that is, the above patented structure does not solve the problem of glue overflow in traditional glass glue guns. The operator often needs to wipe off the overflowed glue with a paper towel, which is not only troublesome, but also causes a lot of waste in the long run. Based on this, it is necessary to propose a glass glue gun that can solve the above technical defects. Utility Model Content

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figures 1 to 6 As shown, a novel glass glue gun includes a handle 1, and a barrel 2 is detachably connected to the handle 1; Figure 4 As shown, a first connecting cover 10 is provided on the handle 1, and a first threaded ring 11 is provided at a corresponding position of the gun barrel 2. The first threaded ring 11 is connected to the first connecting cover 10 through threads, and the inner wall of the first connecting cover 10 has an internal thread corresponding to the first threaded ring 11. Therefore, the detachable connection between the first threaded ring 11 and the first connecting cover 10 facilitates the installation of the gun barrel 2.

[0027] In addition, a second threaded ring 12 is provided at the other end of the gun barrel 2 away from the first threaded ring 11, and the second threaded ring 12 is threadedly connected to a second connecting cover 13; the connection method between the second threaded ring 12 and the first threaded ring 11 is the same as the connection method between the first threaded ring 11 and the first connecting cover 10; the purpose of the above two structures is that when installing or removing the glass glue cylinder in the gun barrel 2, the gun barrel 2 can be separated from the first connecting cover 10 to load or remove the glass glue cylinder from the gun barrel 2; or, the gun barrel 2 can be left unremoved, only the second connecting cover 13 can be removed, the glass glue cylinder can be directly placed in the gun barrel 2 or taken out from the gun barrel 2, and then the second connecting cover 13 can be screwed on, which is very convenient for both the overall installation and the placement and removal of the glass glue cylinder.

[0028] The surface of the gun barrel 2 is sprayed with an anti-rust layer; the anti-rust layer is attached to the surface of the gun barrel 2 by a spraying process to improve the anti-rust effect.

[0029] A push rod 3 is movably provided on the handle 1. When the barrel 2 is connected to the handle 1, the pushing end of the push rod 3 is located in the barrel 2. The push rod 3 is used to push the rear cover of the glass glue cylinder, so as to squeeze out the glass glue in the glass glue cylinder. A trigger 4 is provided below the push rod 3, and the trigger 4 is rotatably connected to the handle 1. A groove section 301 is provided along the length direction of the push rod 3. An elastic push sheet 5 is connected to the trigger 4, and the upper end of the elastic push sheet 5 abuts against the groove section 301. Figure 2 As can be seen, when the handle 1 is held and the trigger 4 is driven to rotate in the direction of the arrow in the figure, the elastic push piece 5 will be driven to rotate forward to push the locking position of the card groove section 301, so that the push rod 3 moves forward in the direction of the arrow in the figure; an elastic limiting piece 6 is provided in the handle 1, and the lower end of the elastic limiting piece 6 is rotatably connected to the handle 1, and the upper end of the elastic limiting piece 6 abuts against the card groove section 301; the elastic limiting piece 6 is used to stop the push rod 3; in the actual structure, a reset torsion spring is provided between the trigger 4 and the handle 1. When the hand relaxes the pressure on the trigger 4, the trigger 4 will rotate back and return to the position under the action of the reset torsion spring. Figure 2 The reset torsion spring structure is a prior art and will not be described here. At this time, the trigger 4 is pressed by the hand to push the push rod 3 again. Each time the push rod 3 moves forward, the elastic limit plate 6 limits the push rod 3 to prevent the push rod 3 from being pushed back, thereby gradually driving out the glass glue in the glass glue cylinder. When the trigger 4 rotates back under the action of the reset torsion spring, the elastic push plate 5 will rotate back to the position of the snap groove section 301 behind the push rod 3. Due to the limiting effect of the elastic limit plate 6 on the push rod 3, the push rod 3 will not move back when the elastic push plate 5 rotates.

[0030] One of the improvements of the utility model is that the handle 1 is also provided with an adjustment structure for bending the elastic limiting piece 6; the adjustment structure includes a rod body 7 and an elastic member 8, one end of the elastic member 8 is connected to the rod body 7, and the other end of the elastic member 8 is connected to the middle of the elastic limiting piece 6. In the present embodiment, the elastic member 8 is a torsion spring, one end of the torsion spring is fixedly connected to the rod body 7, and the other end of the torsion spring is fixedly connected to the middle of the elastic limiting piece 6; a transversely arranged guide groove 101 is provided on the handle 1, and the rod body 7 is movably arranged in the guide groove 101; the two ends of the rod body 7 protrude from the guide groove 101, so the rod body 7 can be bent with fingers to move the rod body 7 to the left or right position of the guide groove 101; and combined with Figure 5 and Figure 6 As can be seen, when the rod body 7 is located at the right side of the guide slot 101, the elastic stopper 6 is in a straight state, and when the rod body 7 is pushed to the left side of the guide slot 101, the elastic member 8 will slightly lift the middle part of the elastic stopper 6, so that the elastic stopper 6 has a certain bending state. Figure 6 It can be seen that when the elastic limiting piece 6 is in a bent state, the upper end position of the elastic limiting piece 6 and the locking position of the latching groove section 301 will have a certain amount of retraction. After the push rod 3 moves forward under the action of the elastic pushing piece 5, when the elastic pushing piece 5 is about to rotate to prepare for the next round of pushing work, since the elastic limiting piece 6 and the locking position of the latching groove section 301 have a certain amount of retraction at this time, the push rod 3 will retreat under the drive of the rotation of the elastic pushing piece 5 until it hits the elastic limiting piece 6. That is, when the rod body 7 is located at the right side of the guide groove 101, the elastic limit plate 6 is in a straight state. At this time, each forward movement of the push rod 3 will maintain the tightening force on the back plate of the glass glue cylinder, which is suitable for the operator to keep shooting for large-throughput construction; and when the rod body 7 is pushed to the left side of the guide groove 101, the elastic limit plate 6 has a certain bending state. At this time, the push rod 3 will retract slightly after each forward movement, and will not maintain the tightening force on the back plate of the glass glue cylinder, that is, the back plate of the glass glue cylinder also has a certain return space (the internal pressure of the glass glue cylinder will cause the back plate to return), which is suitable for the operator to perform intermittent construction. This state achieves the function of preventing glue overflow.

[0031] A passive wheel set 9 is arranged above the push rod 3, and the passive wheel set 9 is rotatably connected to the handle 1; the passive wheel set 9 is connected to the push rod 3; lubricating glue can be injected between the passive wheel sets 9, and when the push rod 3 moves, the passive wheel set 9 rotates to drive the lubricating glue to be applied to the surface of the push rod 3, thereby achieving the purpose of lubrication.

[0032] The end of the push rod 3 is detachably connected with a push head 14, which is fixed to the push rod 3 by means of a threaded connection, so as to facilitate installation and replacement. The push head 14 includes a disc-shaped soft film ring 1401. When the push rod 3 moves forward, the front end of the push head 14 pushes against the back plate of the glass glue cylinder, and the soft film ring 1401 undergoes a certain deformation and bending to connect with the inner wall of the glass glue cylinder, which is beneficial to maintaining the stability of the push head 14 moving in the glass glue cylinder.

[0033] from Figure 2 It can be seen that a limiting arc edge 401 is provided on the trigger 4. As can be seen from the above, the reset torsion spring will cause the trigger 4 to rotate and reset. The design of the limiting arc edge 401 can prevent the trigger 4 from excessively returning to its original position, thereby achieving the purpose of limiting the position; it can also prevent a person's hand from being embedded in the clamping position between the trigger 4 and the barrel 2 and causing injury.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
