Problems solved by technology

But in actual use, this nail gun also has the following defects: 1. Since the gun body of the gun barrel is provided with a nail entry channel, and the length of the channel is greater than the length of the nail, when the nail is fired. , the balance of the nails in the barrel is poor, and the nails are easy to shoot at the slot of the barrel, causing the failure of the barrel to be stuck and unable to fire; at the same time, due to the poor balance of the nails in the barrel, it will also affect the Accuracy of nailing, that is, there is a problem that the nails are missed and the nails are not in place
2. The nail gun uses a separate nail magazine to feed the nails, which makes the entire nail gun heavier, resulting in greater labor intensity
3. The number of nails in the nail box is fixed, so the required number of nails cannot be loaded at one time according to the construction needs, resulting in low construction efficiency
4. Since the nails in the nail box are connected by a plastic connecting belt, there will be plastic residue hanging on the nail cap after firing, which will affect the nailing effect of the nail
However, this screw gun is mainly used for screwing screws, and it must be connected to the power supply through the power cord when in use, which is not conducive to construction

Embodiment 1

[0041] A chain belt nail gun, comprising a gun barrel, a safety pressure plate 3, a gun barrel cover 5, a nail feeder for chain belt nail shooting, a gun body 1, an action mechanism, a backstop device and a trigger 2, the gun barrel The movable sleeve is set in the barrel cover 5, and the backstop device includes a backstop plate 24 and a torsion spring 11, and the torsion spring 11 and the backstop plate 24 are fixed on the lower part of the barrel cover 5 by a cotter pin 15, and on the backstop plate 24 A clip for clamping the connecting band is provided, and the torsion spring 11 cooperates with the stop plate 24 to clamp the connecting band through the clamping bar to prevent it from going backwards. The gun barrel cover 5 is fixed on the gun body 1, and the gun barrel cover 5 is provided with a nail inlet and a connection belt outlet. The nail feeder sends the nails into the gun barrel cover 5 through the nail inlet. , the connecting tape is discharged from the connecting...

Embodiment 2

[0048] This embodiment is basically the same as the above-mentioned embodiment, the main difference is that: the gun barrel includes a gun mouth 26 and a gun body 27, a limiting platform is arranged between the gun mouth 26 and the gun body 27, and a limiting groove 28 is arranged on the gun body 27 , this limit groove 28 is not communicated with the barrel inner tube, the barrel cover 5 is provided with a limit bolt 4, after the gun barrel is inserted into the barrel cover 5, the end of the limit bolt 4 is located in the limit groove 28.

[0049] The preferred implementation of this embodiment is that two symmetrical grooves 16 are arranged on the side wall at the end of the gun body 27, and the grooves 16 are not communicated with the limiting groove 28. When the gun barrel is pressed down, the gun will When the pipe moves toward the gun body 1, the two grooves 16 correspond to the nailing inlet and the connecting belt outlet on the barrel cover 5 respectively. This structure...

Embodiment 3

[0051] A chain belt nailing special for a nail gun, including a strip-shaped chain belt 29 and a nail, the chain belt 29 is a long plastic chain belt 29, the chain belt 29 is an integrated structure, and the chain belt 29 is Evenly be provided with through-hole 31, and each through-hole 31 is provided with boss 30, and described through-hole 31 runs through the center (geometric center) of boss 30, (or evenly be provided with boss on chain belt 29 platform 30, the chain belt 29 is provided with a through hole 31 running through the chain belt 29 and the center of the boss 30), the nails pass through the chain belt 29 and the through hole 31 on the boss 30 in turn, and the nails are passed through the through hole 31 is fixed, and the described nail feeding groove 32 for continuous supply of nails is provided between the adjacent through holes 31. The nail feeding groove 32 is a gap located on the outside of the chain belt 29, and the circumference of the through hole 31 is alon...

Abstract

The invention discloses a chain belt nail gun. The chain belt nail gun comprises a nail conveying device, an actuating mechanism, a retaining device and a trigger, wherein the nail conveying device is used for chain belt type nailing; the retaining device is fixed on a gun barrel sleeve; a nail inlet and a connection belt outlet are formed in the gun barrel sleeve; the nail conveying device comprises a fixing seat and a nail pushing part; the fixing seat is fixedly connected with the gun barrel sleeve; the nail pushing part is elastically connected with the fixing seat, and is positioned below the nail inlet; a security pressing plate is movably connected with the nail pushing part; one end of the actuating mechanism is movably connected with a gun barrel, and the other end of the actuating mechanism is matched with the nail pushing part to control the security pressing plate; when the actuating mechanism moves toward the direction of a gun body, the actuating mechanism drives the nail pushing part to move downward, and enables the trigger to be in a percussion state; when the actuating mechanism moves toward the direction of the gun barrel, the fixing seat and the nail pushing part are matched to convey nails. The chain belt nail gun provided by the invention can solve the following technical problems that firstly, the gun barrel is blocked by nails; secondly, the weight of the nail gun is heavy; thirdly, plastic residues can be hung on nail caps after percussion.

Description

technical field [0001] The invention relates to a decoration tool, in particular to a nail gun with a chain belt, which is mainly used for directly driving nails connected by a connecting belt into hard substrates such as steel, concrete, brick masonry or rocks middle. Background technique [0002] The nail gun is a commonly used tool in construction and decoration industries. It can instantly inject nails into the matrix. Compared with traditional expansion bolts, using a nail gun to shoot nails has the advantages of saving time, labor and high construction efficiency. advantage. [0003] At present, the commonly used nail gun with compressed air as the power source, its structure usually includes a gun head, a gun body, a safety device, a trigger and a nail box. For example, Chinese Patent No. "201320035080.5" discloses a compressed air nail gun, and its publication date is August 14, 2013. The nail gun mainly sends nails to the gun head through a separate nail feedi...
