Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, and more specifically, to a caulking gun for building construction. Background Art

[0002] In the process of building construction, in order to evenly apply materials such as glue or sealant to the construction surface, a caulking gun is often used. Traditional caulking guns usually consist of a gun body, a gun nozzle and a pressure rod. When using it, you need to hold the gun body with your hand, aim the gun nozzle at the construction surface, and then apply pressure through the pressure rod to squeeze out the glue or sealant and apply it to the construction surface.

[0003] Traditional caulking guns require manual pressure to apply glue when in use. Without the assistance of a ladder, when caulking a construction surface that is too high, people need to stand on tiptoe and stretch their hands to the highest point. It is not convenient to use both hands to apply glue. Operating with one hand will result in unstable caulking, resulting in poor application effect and inconvenient operation. After working for a long time, the palms will become tired and sore, resulting in reduced work efficiency. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a caulking gun for building construction, which has the advantage of convenient operation.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model controls the motor to be turned on by moving the control button downward to trigger the controller. The output shaft of the motor provides power to drive the second gear to rotate, so that the second gear drives the first gear to rotate. Since the first gear and the threaded rod are threadedly sleeved, when the first gear rotates, the threaded rod is driven to translate left and right inside the first gear, and the glue is pressed out from the glue outlet head. Compared with the traditional caulking guns used in construction, the new control mechanism controls the motor to be turned on by the manual triggering of the controller, so that the motor drives the first gear to drive the threaded rod and the glue pushing block to press the glue.

[0030] The control mechanism includes a gear 14 and a gear 2 15 movably mounted on the inner wall of the casing 4, and also includes a motor 16 fixedly mounted inside the casing 4. The gear 14 is meshed with the gear 2 15. The internal thread of the gear 14 is sleeved with a threaded rod 13. The output shaft of the motor 16 is fixedly connected to the gear 2 15. A rubber pushing block 12 is fixedly mounted on the top of the threaded rod 13. The rubber pushing block 12 is located inside the rubber pressing tube 5.

[0031] The staff member presses the control button 3 with his finger, so that the control button 3 moves downward to trigger the controller 21. When the controller 21 is triggered, the motor 16 is controlled to be turned on. The output shaft of the motor 16 provides power to drive the gear 2 15 to rotate, so that the gear 2 15 drives the gear 1 14 to rotate. Since the gear 14 and the threaded rod 13 are threadedly connected, when the gear 14 rotates, it drives the threaded rod 13 to translate left and right inside the gear 14, and presses the glue out of the glue head 6.

[0032] The control button 3 is moved downward to trigger the controller 21 to start the motor 16. The output shaft of the motor 16 provides power to drive the gear 2 15 to rotate, so that the gear 2 15 drives the gear 1 14 to rotate. Since the gear 14 and the threaded rod 13 are threadedly connected, when the gear 14 rotates, the threaded rod 13 is driven to translate left and right inside the gear 14, and the glue is pressed out from the glue head 6.
