Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to a double-hole adhesive application device for door seal strips. Background Technology

[0002] In door and window installation and sealing operations, the caulking process has a significant impact on the sealing effect and appearance quality. Existing caulking guns typically have only one nozzle, resulting in low caulking efficiency. Furthermore, due to the lack of an effective positioning structure during operation, the caulking gun is prone to shaking, leading to uneven caulking, misalignment, and even caulking that spills and contaminates the door frame surface. This not only affects the aesthetics but may also require rework and cleaning, increasing construction time and wasting materials. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, this utility model proposes a double-hole glue applicator for door sealant strips. Specifically, it includes the following:

[0004] A double-hole adhesive applicator for door sealant strips includes an adhesive gun body, a gun head at the front end of the adhesive application wall, the gun head being elliptical cylindrical, and having two adhesive outlets on the gun head, forming two adhesive lines simultaneously during application. A positioning rod is provided on one side of the adhesive gun body near the gun head, and the positioning rod moves close to the edge of the door frame, serving as a guide and limiting mechanism.

[0005] Furthermore, the end of the positioning rod extends beyond the glue outlet, with the positioning rod extending outward by 4 to 5 centimeters beyond the glue outlet.

[0006] Furthermore, the positioning rod is a slender strip made of stainless steel.

[0007] The above technical solution has the following beneficial effects:

[0008] This invention features a positioning rod at one end of the glue gun body, which prevents the glue gun from shaking when moving along the door frame, ensuring that the glue is accurately applied to the predetermined position, avoiding glue overflow and pollution, reducing rework and material waste. The design of two glue outlets makes the glue distribution more even, and double-line glue application can be completed in one operation, improving work efficiency. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] See Figures 1-3 The illustrated dual-hole adhesive applicator for door sealant strips includes an applicator gun body 1, a gun head 2, and a positioning rod 3. The applicator gun body 1 is a handheld structure with an internal cavity for accommodating the adhesive cartridge and equipped with a conventional adhesive pushing mechanism, such as a trigger or push rod. The gun head 2 is mounted at the front end of the applicator gun body 1 and communicates with the adhesive path inside the gun body. The positioning rod 3 is fixed to the side of the applicator gun body 1 near the gun head 2.

[0015] The gun head 2 has an elliptical cylindrical structure, and two glue outlets 4 are provided at the end of the gun head 2. The distance between the two glue outlets 4 is 0.5-1 cm, and the diameter of the glue outlets 4 is the same to ensure that the glue output and diameter of the two glue lines are uniform.

[0016] Positioning rod 3 is a slender rod made of stainless steel. Positioning rod 3 is welded to the side of the caulking gun body 1. Its installation position must ensure that positioning rod 3 is flush against the edge of the door frame during caulking.

[0017] The end of the positioning rod 3 must extend beyond the glue outlet 4 on the gun head 2. The specific extension length L is limited to between 4 and 5 centimeters. This is to prevent the positioning rod 3 from detaching from the edge of the door frame during user movement.

[0018] In practical use, the positioning rod 3 of the glue gun body 1 is engaged with the edge of the door frame, ensuring the positioning rod 3 is flush against the side of the door frame. The glue gun body 1 is then held and moved smoothly along the door frame, and the glue is simultaneously extruded from both nozzles 4, evenly spreading across the door frame. Because the end of the positioning rod 3 extends beyond the nozzles 4, it contacts the door frame and provides guidance before the glue is extruded, ensuring a straight path for the glue gun and resulting in neat and accurate glue lines. The design of two nozzles 4 allows for more even glue distribution, enabling double-line glue application in a single operation, significantly improving work efficiency. The entire device has a simple structure and is easy to operate.

[0019] The basic principles and main features of this utility model have been described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
