Description

Nail gun with buffer dust cover

The present invention relates to a nail gun with a buffer dust cover.

According to the general nail gun, when the nail is hit at high speed, the high-speed impact of the target will cause dust to be spattered everywhere, which will not only cause the working environment to be dirty and dusty, so there is a dust collection on the market. a dust cover is mounted on the muzzle of the nail gun, and the dust cover is placed against the target and covers the target object, and when the target object is impacted by the nail, the dust is The dust cover is covered and does not spatter everywhere. The nail gun disclosed in TWM548052 is such.

However, since the nailing force is strong after the nail gun is shot, the nail gun and the dust collecting cover move in a direction away from the target when the nail is launched, which may cause the dust collecting cover to fail smoothly. The ground cover is placed on the target, and the dust is still inadvertently sputtered, and there is a drawback that needs to be improved.

Therefore, it is necessary to provide a novel and progressive nail gun with a buffer dust cover to solve the above problems.

The main object of the present invention is to provide a nail gun with a dust collecting cover, which can effectively prevent the nail gun from being fired in a direction away from the target, and the cover can effectively abut the target. To prevent dust from being spattered.

In order to achieve the above object, the present invention provides a nail gun with a buffer dust cover, which comprises a barrel, a cover and an elastic member. The barrel has a muzzle at one end and the muzzle is for receiving a nail body. The cover body is slidably sleeved on the barrel and encloses an accommodating space. The elastic member is disposed between the cover body and the barrel so that the cover body normally moves toward the muzzle of the barrel.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIGS. 1 through 6, there is shown a preferred embodiment of the present invention. The nail gun with a buffer dust cover of the present invention comprises a barrel 1, a cover 2 and an elastic member 3.

The barrel 1 has a muzzle 11 at one end and the muzzle 11 is for receiving a nail body 9. The cover body 2 is slidably sleeved on the barrel 1 and defines an accommodating space 21 . The elastic member 3 is disposed between the cover 2 and the barrel 1 such that the cover 2 is normally moved toward the muzzle 11 of the barrel 1.

Specifically, the barrel 1 has a first rib 12 radially adjacent to one end of the muzzle 11 , and the first rib 12 blocks the cover when the cover 2 is moved to the muzzle 11 The body 2 is such that the cover 2 cannot be detached from the barrel 1. In detail, the barrel 1 is provided with a ring groove 13 adjacent to one end of the muzzle 11 , and the first rib 12 is a ring fastener 14 , and the ring fastener 14 is detachably fastened to the ring Slot 13, in this real In the embodiment, the ring fastener 14 is a C-shaped buckle for easy disassembly. After the ring fastener 14 is removed, the cover 2 can be detached from the barrel 1.

The elastic member 3 is elastically biased between the second retaining edge 15 and the cover body 2, The elastic member 3 is normally pushed against the muzzle 11 in the direction of the muzzle 11 . In the embodiment, the second retaining edge 15 is integrally formed by the barrel 1 .

Further, the cover body 2 includes a disk body 22 and a ring body 23, and the ring body 23 is slidably sleeved on the barrel 1 , and the disk body 22 integrally extends from the ring body 23 , the disk body 22 is in the shape of a bowl and surrounds the accommodating space 21 to effectively cover an object (such as a wall).

In the embodiment, the sliding sleeve 4 is further slidably sleeved on the barrel 1 , and the ring body 23 is sleeved on the sliding sleeve 4 and cannot slide relative to the sliding sleeve 4 . The sliding sleeve 4 prevents the ring body 23 from coming into contact with the barrel 1 to generate a frictional force, and additionally prevents the ring body 23 from being worn. Preferably, the sliding sleeve 4 is made of metal material to achieve wear resistance and smooth sliding along the barrel 1. The cover body 2 is made of rubber material or plastic material, so that the cover body 2 can be slightly deformed to fit closely. In the object, the sliding sleeve 4 is remote from the one end of the muzzle 11 and has a third retaining edge 41 radially toward the periphery. The cover 2 abuts against the third retaining edge 41 so that the cover 2 abuts. The sliding sleeve 4 can be smoothly driven when it is slid in the direction of the second rim 15 against the target.

In actual operation, the cover 2 is firstly abutted against the target and covers the target, and the cover 2 is moved away from the muzzle 11 by a distance (as shown in FIG. 5). When the gunpowder explosion generates an impact force and the nail body 9 is emitted toward the outside of the muzzle 11, the nail gun of the buffer dust collecting cover generates a recoil force and moves away from the target object due to the cover body. 2 is moved away from the muzzle 11 by a distance, and when the nail gun with the buffer dust cover moves away from the target, the cover 2 is pointed by the elastic member 3 toward the muzzle The direction of the 11 is rebounded (ie, the top is toward the target) so that the cover 2 still abuts against the target (as shown in FIG. 6), and the nail 9 hits the target Time The generated dust is covered by the cover 2 and cannot be sputtered, so that the nail gun with the buffer dust cover can effectively prevent dust from being sputtered.

It should be noted that, in this embodiment, the barrel 1 includes an outer tube 16 and an inner tube 17, and the inner tube 17 is provided with the muzzle 11 at one end thereof, and the outer tube 16 is sleeved on the opposite side. The inner tube 17, the gas can be discharged from the vent hole of the inner tube 17 to the outer tube 16, so that the gas is not immediately discharged to the outside through the muzzle 11, and the flow rate of the gas discharged to the outside unit can be reduced. The cover body 2 is slidably disposed on the outer tube 16 , and the first rib 12 and the second rib 15 are disposed on the outer tube 16 . In other embodiments, the barrel 1 is provided. The outer tube 16 may not be included, and the cover body 2, the first rib 12 and the second rib 15 are directly disposed on the inner tube 17.

In addition, the nail gun with the buffer dust cover may further include a connecting rod 5 connected to the inner tube 17 away from one end of the muzzle 11 and communicating with the inner tube 17, the connection The ejector rod 51 is further slidably disposed in the rod 5, and the ejector rod 51 is selectively pushed in the direction of the muzzle 11 to bring the explosive after the explosion to the muzzle 11 to reach the shell. Features.

In summary, the nail gun with a buffer dust cover of the present invention is slidably disposed on the barrel by the cover body, and the elastic member normally moves the cover body toward the muzzle, when the cushion is buffered. When the nail gun of the dust collecting cover generates a recoil force and moves away from the target, the cover still abuts against the target and effectively prevents dust from being sputtered.
