Problems solved by technology

[0003] At the same time, there are also pneumatic nail guns on the market to fasten the cement, but the pneumatic nail gun also needs a compressor to supply air, which increases equipment and costs, and is poor in portability and transportation.

Embodiment 1

[0048] Embodiment one: if Figure 1-12 As shown, a cement nail gun includes a cylinder 1, and a piston assembly 2 is slidably arranged in the cylinder 1. The piston assembly 2 is used to discharge the air at the rear end of the piston assembly 2 and form a vacuum at the front end of the compression piston assembly 2 during the movement. cavity 11; the front end of the piston assembly 2 is provided with an impact head 21, and the front end of the impact head 21 is provided with a striker 12; the rear end of the piston assembly 2 is connected with a driving device 3, and the driving device 3 is used to drive the piston assembly 2 in the The cylinder 1 moves and fires the striker 12 to move.

[0049] The technical solution specifically describes a cement nail gun that utilizes the pressure difference between the inside and outside of the atmosphere as power for nailing operations. Specifically, in actual use, when the driving device 3 drives the piston assembly 2 to move toward ...

Embodiment 2

[0091] Embodiment two, such as Figure 5 and Figure 8 As shown, this embodiment is basically the same as Embodiment 1, and the difference lies in that "the mounting hole 331 is formed on one side of the locking pawl 33, and the upper end of the mounting seat 34 is provided with a limiting pressing piece 35, which limits A tension spring 36 is arranged between the position pressing piece 35 and the mounting hole 331, and this part of the technical solution can be replaced by "a return torsion spring abuts between the mounting seat 34 and the locking pawl 33." 332". That is to say, a reset torsion spring can be arranged at the front end of the locking pawl 33 , so that there is always a force to drive the locking pawl 33 against the rack pull rod 31 . This makes the sliding process of the rack rod 31 smoother and labor-saving.

Embodiment 3

[0092] Embodiment 3, this embodiment is basically the same as Embodiment 1, the difference lies in that the rear limit pin 37 also has a function as a signal for the rack pull rod 31 to move to the set position. Specifically, at this time, the tooth surface height of the rack pull rod 31 should be designed "from high to low" from the front end to the rear end. When the rack pull rod 31 moves to the set position, the distance between the lower end of the locking pawl 33 and the rear limit pin 37 becomes smaller and smaller as the tooth surface is lifted. 31 just can't move, and performance is exactly that hand wheel can not be shaken again externally, and this moment then represents rack pull bar 31 and can enter the percussion step in place.

[0093] Such a design has a function of prompting and limiting. Can tell the user when to stop. In this embodiment, "from high to low" does not represent a linear change process, and it can also be one of the teeth on the rack rod 31. I...

Abstract

The invention discloses a cement nail gun, and belongs to the technical field of fastening. The cement nail gun comprises a cylinder; a piston module is slidingly arranged in the cylinder, and is usedfor compressing air at the back end of the piston module in the moving process and compressing the front end of the piston module to form a vacuum cavity; a collision head is arranged at the front end of the piston module; a collision pin is arranged at the front end of the collision head; the back end of the piston module is connected with a driving device; and the driving device is used for driving the piston module to move in the cylinder and driving the collision pin to move. Preferentially, the driving device comprises a rack pull rod; a driving gear is arranged on the outer side of thecylinder; and the driving gear is matched and engaged with the rack pull rod. The atmospheric pressure difference between the front and back ends in the cylinder is used as power for driving the piston to move. Mechanical structures are adopted in the whole process, and no gunpowder or no air compressor is used as an external power source, so that higher environmental protection and safety are achieved, the use is more convenient, and an external power supply is not needed.

Description

technical field [0001] The invention belongs to the field of fastening technology, in particular to a cement nail gun. Background technique [0002] At present, the traditional method of domestic ceiling installation is: tie an impact drill to the end of a long rod, the operator holds the long rod to make the impact drill drill holes in the bottom of the ceiling and install expansion bolts, install the boom on the bolts, and then install the expansion bolts on the boom. Construction methods for installing suspended ceilings. Traditional methods are time-consuming, labor-intensive, costly, and labor-inefficient. Gunpowder nail guns have appeared on the market in recent years, and its principle is to drive steel nails into cement by using gunpowder explosion. Its advantages are obvious, greatly reducing the labor intensity. [0003] At the same time, there are also pneumatic nail guns on the market to fasten the cement, but the pneumatic nail guns also need a compressor to ...
