Description

Technical Field

[0001] The utility model relates to the technical field of sealant application tools, in particular to a glue gun with an adjustable angle. Background Art

[0002] There are various types of glue guns on the current market, including straight nozzle type, right-angle nozzle type, 45° nozzle type, etc., but they are all fixed special-angle glue guns. These fixed special-angle glue guns have obvious deficiencies in the actual application process: First, the nozzles are all fixed nozzles and can only be used at specific angles. During the construction process, it is necessary to frequently replace them back and forth according to the construction needs. The replacement is troublesome, and the sealant will waste and flow out during the replacement, which is easy to pollute the surrounding environment. Second, since most of the nozzles of the glue guns on the market have only one fixed angle, they may not be applicable in actual construction. Especially, the external joints at the lower part of the pipeline during construction are affected by the construction space, and it is difficult for personnel to apply glue. This inadaptability will seriously affect the work efficiency.

[0003] In order to overcome the above problems, a glue gun head with a bent nozzle is often used in the prior art. For example, the patent document with the authorization announcement number CN206911668U discloses a glass glue gun nozzle, which adopts a structural form of a metal discharge nozzle made of a metal material and a glass glue gun nozzle body formed with a certain glue application angle. However, this solution still has some limitations, such as single angle, difficult to adjust, etc. In view of this, it is particularly important to find a glue gun with an adjustable angle. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Refer to Figures 1-6, An adjustable-angle glue gun, comprising a gun body 1, a handle 2, a trigger 3 and a push rod 4. A cylinder body 5 is arranged on the gun body 1, and a gun head assembly is arranged at the front end of the cylinder body 5. The gun head assembly includes a nozzle 6 communicated with the cylinder body 5, and a glue outlet pipe 7 is connected to the nozzle 6. One end of the glue outlet pipe 7 is sleeved on the nozzle 6, and an adjustment assembly for adjusting the angle of the glue outlet pipe 7 is arranged between the glue outlet pipe 7 and the gun body 1; A pressing assembly is further arranged on the handle 2, and the pressing assembly is used to drive the push rod 4 to move along the axial direction of the glue cylinder when the trigger 3 is pressed, so as to extrude the sealant.

[0028] Specifically, the adjustment assembly includes a bracket 8 installed on the gun body 1 and a slider 9 slidably arranged on the bracket 8. One side of the slider 9 is provided with a connecting rod 10, and one end of the connecting rod 10 is hinged to the end of the glue outlet pipe 7 far from the nozzle 6.

[0029] Further, a long slot 11 is vertically opened on the bracket 8. The slider 9 is of an I-shaped structure. The slider 9 includes a base body and side ears located at both ends of the base body. The base body of the slider 9 is located in the long slot 11. By adjusting the position of the slider 9 on the bracket 8, the pull rod is deflected, so that the glue outlet pipe 7 is bent, and thus the glue application angle can be flexibly adjusted.

[0030] Please refer to again Figure 6 , A threaded hole is opened on one of the side ears of the slider 9, and a wing bolt 12 is inserted into the threaded hole, which is convenient for hand-tightening operation. When the wing bolt 12 passes through the threaded hole on the slider 9 and abuts against the bracket 8, the slider 9 is fixed.

[0031] Please refer to again Figure 4 , A connecting plate 13 is arranged on the other side ear of the slider 9. The connecting plate 13 and the connecting rod 10 are connected by a wing bolt 14. The wing bolt 14 sequentially passes through the connecting rod 10 and the connecting plate 13, and a nut 15 is sleeved on the wing bolt 14. After the sliding is fixed, the wing bolt 14 is tightened, and the pull rod is kept fixed, so as to keep the adjusted angle of the glue outlet pipe 7.

[0032] As an implementable manner, the long slot 11 penetrates through the top of the bracket 8, and a plug 16 is arranged on the top of the bracket 8, which is convenient for putting the slider 9 into the long slot 11 and facilitating assembly.

[0033] In the present utility model, the pressing assembly includes a baffle 17 connected to the trigger 3. A first spring 18 is arranged on the right side of the baffle 17, a second spring 19 is arranged on the left side of the baffle 17, and a check plate 20 is arranged on the left side of the second spring 19. The push rod 4 sequentially passes through the first spring 18, the baffle 17, the second spring 19 and the check plate 20.

[0034] Through the above set structure, please refer to again Figure 2, when the trigger 3 is pressed, the baffle 17 is driven. The baffle 17 comes into force contact with the push rod 4 and forms motion transmission. The push rod 4 moves forward. When the trigger 3 is released, the first spring 18 drives the baffle 17 to return to its original position. And the check plate 20 is inclined at a certain angle due to the force of the second spring 19, comes into force contact with the push rod 4, and prevents the push rod 4 from moving backward. Therefore, during normal caulking, the push rod 4 will only move forward and will not retract, so that the sealant is continuously extruded from the nozzle 6 through the push plate 21. When the check plate 20 is pressed, the check plate 20 is perpendicular to the push rod 4. At this time, the push rod 4 can be pulled backward for resetting.

[0035] In addition, the push rod 4 passes through the inside of the cylinder body 5. A push plate 21 is provided at the front end of the push rod 4, and a hook 22 is integrally provided at the rear end of the push rod 4. After each caulking stroke is completed, it is convenient to pull the hook 22 to retract the push rod 4 backward. After resetting, new sealant can be replenished into the cylinder body 5 and then the push rod 4 is pushed back again, and the push plate 21 is re-abutted against the sealant to prepare for the next caulking work.

[0036] The working principle of the present utility model is as follows:

[0037] When the angle of the glue outlet pipe 7 needs to be adjusted, please refer to Figure 2 again. Loosen the wing bolt 12 and the wing bolt 14. The hand-held slider 9 can move up and down in the long slot 11. By adjusting the position of the slider 9 on the bracket 8, the pull rod is driven to deflect, so that the glue outlet pipe 7 is bent to the required angle. Then tighten the wing bolt 12 to fix the slider 9. Finally, tighten the wing bolt 14, and the pull rod remains fixed, so as to maintain the adjusted angle of the glue outlet pipe 7. After the angle of the glue outlet pipe 7 is adjusted, press the trigger 3 to extrude the sealant, so that the sealant can flow out from the outlet of the glue outlet pipe 7 for construction, which is convenient and fast to use.

[0038] In summary, the present utility model realizes the adjustment of the caulking angle by setting the adjustment assembly, meets different caulking requirements, is simple and convenient to operate, and has strong practicability.
