Description

Muzzle mechanism that reduces displacement path

This invention relates to a muzzle mechanism, and in particular to a muzzle mechanism capable of reducing the displacement path.

When the nail gun is used to eject nails, the gap between the nail and the muzzle is 2.8mm, which will cause the nail to move to a certain extent after being driven. The above displacement will cause the nail to fall on the workpiece with a larger distance after each shot, thus affecting the appearance of the workpiece, and may have an adverse effect on the neatness and aesthetics of the workpiece surface, especially in applications that require high precision and neat appearance.

If nails can be fired and positioned in a more accurate and consistent manner, it will help improve the smoothness and aesthetics of the workpiece surface after nailing. Therefore, there is still room for improvement in the muzzle of nail guns.

In order to solve the above problems, this invention provides a gun muzzle mechanism that can reduce the displacement path and reduce the offset when the nail is driven out.

In order to achieve the above-mentioned purpose, the invention provides a gun muzzle mechanism that can reduce the displacement path, including a main guide plate, a push plate, a safety piece, a limit sleeve, a pressing piece and a cover plate. The side of the main guide plate has a groove, and the main guide plate has two parallel and symmetrically arranged slide rails, and there is a long nail hole, a split groove and a push nail groove between the two slide rails. The push nail groove is located above the long nail hole and the split groove, and the long nail hole is not connected to the split groove. The end of the push plate has a push needle block, and the bottom of the push plate is parallel to two slide grooves, and the slide grooves are arranged correspondingly on the slide rails, so that the push needle block can slide in the push nail groove. The safety piece has a fixing plate, and the fixing plate is arranged in the groove. A guide protrusion is convexly provided on the top surface of the limit sleeve, and a side wall plate is extended upward on both sides of the top surface of the limit sleeve. The limit sleeve is sleeved on one end of the slide rail adjacent to the cutout groove, and the side wall plate is covered on the outer side wall of the corresponding slide rail, and the guide protrusion is arranged below the cutout groove. One end of the abutment member forms an abutment edge, and the abutment member is sleeved and fixed on the bottom surface of the limit sleeve, and at the same time, one end of the limit sleeve is attached to the inner wall surface of the abutment edge. The bottom surface of the cover plate is a plane with a concave arc-shaped limit groove, and the cover plate is arranged on the top of the main guide plate so that the limit groove is located above the push nail groove.

Based on the above, this invention adopts the combination of the limit sleeve and the main guide plate, so that the guide protrusion is located below the slot, thereby effectively limiting the inner diameter of the muzzle. In operation, the up and down displacement amplitude of the nail after firing is reduced, and the nail can be shot to the surface of the workpiece more stably, ensuring that the position of the nail is more accurate. Since the displacement amplitude of the nail is reduced, the spacing between the nails can be maintained within a relatively consistent range, which helps to maintain the neatness and beauty of the surface of the workpiece.

Various objects in the embodiment are depicted according to the proportion, size, deformation or displacement suitable for the explanation, rather than being drawn according to the proportion of the object.

The directional terms mentioned in this work, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", etc., are merely diagrammatic directions; therefore, the directional terms used are intended to explain and understand this work, rather than to limit this work, and it is appropriate to state this in advance.

1 to 7 , the invention discloses a gun muzzle mechanism capable of reducing the displacement path, including a main guide plate 10 , a push plate 20 , a safety member 30 , a limit sleeve 40 , a pressing member 50 and a cover plate 60 .

The main guide plate 10 has a groove 11 on its side. The main guide plate 10 has two parallel and symmetrically arranged slide rails 12. There is a nail-entry long hole 13, a split groove 14 and a push-nail groove 15 between the slide rails 12. The push-nail groove 15 is located above the nail-entry long hole 13 and the split groove 14. The nail-entry long hole 13 and the split groove 14 are not connected.

The push plate 20 has a push pin block 21 at its end. Two slide grooves 22 are parallelly recessed at the bottom of the push plate 20 . The slide grooves 22 are correspondingly arranged on the slide rails 12 , so that the push pin block 21 can slide on the push pin groove 15 .

The fuse 30 has a fixing piece 31 at one end. The fixing piece 31 is disposed in the groove 11 .

A guide protrusion 41 is convexly provided on the top surface of the limiting sleeve 40, and a side wall plate 42 is extended upward on both sides of the top surface of the limiting sleeve 40. The limiting sleeve 40 is sleeved on one end of the slide rail 12 adjacent to the groove 14, and the side wall plate 42 is covered on the outer side wall of the corresponding slide rail 12, and the guide protrusion 41 is arranged below the groove 14.

One end of the abutting member 50 forms an abutting edge 51 . The abutting member 50 is sleeved and fixed on the bottom surface of the limiting sleeve 40 . Meanwhile, one end of the limiting sleeve 40 abuts against the inner wall surface of the abutting edge 51 .

The bottom surface of the cover plate 60 is flat and has an arc-shaped limiting groove 61 concavely formed therein. The cover plate 60 is disposed on the main guide plate 10 so that the limiting groove 61 is located above the push pin groove 15 .

2A and 2B, the fixing plate 31 has a curved side wall surface, and the side wall surface is bent at at least one angle. In addition to being bent in accordance with the shape of the side of the main guide plate 10, multiple angles can also provide expansion deformation margins to reduce the possibility of deformation and damage of the fuse 30.

2A and 2B , a reinforcing portion 16 is provided at the bottom of the main guide plate 10 between the long nail hole 13 and the slot 14 , and both ends of the reinforcing portion 16 extend in a direction different from the slot 14 . The reinforcing portion 16 can enhance the structural strength of the main guide plate 10 .

Please continue to refer to Figures 2A and 2B in conjunction with Figures 6 and 7. A slope 131 is provided on the hole wall of one end of the nail entry hole 13 adjacent to the cutout groove 14. The slope 131 gradually expands from the nail entry hole 13 toward the push nail groove 15. In other words, the slope 131 is inclined according to the firing direction of a nail 70, so that the nail 70 can be displaced along the direction of the slope 131 when fired.

Please continue to refer to Figures 3 and 4 in conjunction with Figure 1. The side wall plate 42 is respectively provided with a fixing hole 421, and two fixing flanges 52 are provided on the corresponding inner edge of the abutment member 50. The fixing flanges 52 are correspondingly embedded in the fixing holes 421, which helps to ensure that the abutment member 50 can be firmly fixed at the desired position and is not easy to move or shake.

In addition, an outer ring groove 53 is formed around the outer wall of the abutment member 50, and the outer ring groove 53 is tightly fitted by a reinforcing member 54. The two ends of the outer ring groove 53 form a clamping convex edge 531. The position of the reinforcing member 54 corresponding to the clamping convex edge 531 is bent to form a limiting concave portion 541, and the limiting concave portion 541 is embedded and attached to the corresponding clamping convex edge 531. The above structure helps to enhance the overall structural strength of the abutment member 50, reduce possible deformation or damage, and can also effectively fix the abutment member 50 in the outer ring groove 53 to prevent it from excessive displacement or falling off.

Please continue to refer to FIG. 6 and FIG. 7 in conjunction with FIG. 4 . First, the abutting edge 51 is pressed against the surface of a workpiece 80. After the push plate 20 is fired, the reaction force acts on the cover plate 60. The nail 70 is pushed toward the gun mouth by the push needle block 21 and moves along the push nail groove 15 until it is shot into the workpiece 80. When the nail 70 passes through the limit sleeve 40, the guide protrusion 41 provides support for the nail 70, so that a height H is formed between the nail 70 and the guide protrusion 41. The range of the height H is between 0 mm and 0.5 mm.

Please continue to refer to FIG. 6 and FIG. 7 in conjunction with FIG. 4 . The guide protrusion 41 has a first end 411 and a second end 412. The first end 411 is a square column, and the second end 412 is gradually inclined in a direction different from the first end 411. The inclination angle of the second end 412 helps the nail 70 to pass through the guide protrusion 41 along the angle, reducing the situation where the nail 70 is stuck on the second end 412 of the guide protrusion 41. In addition, the length of the guide protrusion 41 is more than half of the length of the limit sleeve 40, thereby increasing the supporting area under the nail 70, so that more area of the nail 70 is abutted by the guide protrusion 41 before firing, greatly reducing the displacement of the nail 70 after firing.

With the above structure, the advantages of this creation are as follows:

1. Improved stability of the nail 70: Due to the small height H, the up and down deflection of the nail 70 after firing is limited, reducing the displacement amplitude, making the landing point of the nail 70 more stable, which helps to form a neat and uniform arrangement of the nails 70 on the surface of the workpiece 80.

2. Improve working accuracy: After firing, the nail 70 can move more accurately along the nail pushing groove 15 due to the support of the guide protrusion 41, thereby ensuring the accurate position of the nail 70 and improving the working accuracy.

3. Reduce the impact of reaction force: The firing reaction force is concentrated on the cover plate 60, and the limit sleeve 40 and other components are relatively stable, which is conducive to the accurate firing of the nail 70.

The above examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Any modification or change that does not violate the spirit of the present invention is within the scope of protection of the present invention.
