Description

Technical Field

[0001] The invention relates to a pneumatic nail gun component, in particular to a nail limiting and pressing piece device of a pneumatic nail gun. Background Art

[0002] Pneumatic nail guns are also called pneumatic nailing machines. Pneumatic nail guns are a type of equipment that uses the air pressure generated by an air pump (air compressor), small gun air pressure〔4-6.5Kg / c㎡(Bar)〕, large nail gun air pressure〔5-8Kg / c㎡(Bar)〕 as a power source, and uses high-pressure gas to drive the firing pin in the nail gun cylinder to do hammering motion, nailing the nails in the nail clip into the object or firing the nails out, or fixing the nails on the object in a rolled manner. The nails used in this pneumatic nail gun are collectively called pneumatic gun nails.

[0003] Pneumatic nail guns have been widely used in various production occasions. In order to adapt to various production scenarios, pneumatic nail guns are equipped with nails of different specifications, so the nails have different lengths. Since the length of the nail entry of the pneumatic nail gun is fixed, when using longer nails, the nails can be well positioned by using the length of the nail entry and can remain stable during the firing process; however, when using shorter nails, a certain gap is generated between the nail and the nail entry, so the nail is prone to displacement or even rotation in the gun mouth during transportation and firing, which makes it easy for the pneumatic nail gun to get stuck, thereby increasing the failure rate of the nail gun, extending the maintenance assistance time of the pneumatic nail gun, and reducing the efficiency of the use of the pneumatic nail gun. Summary of the invention

[0004] The purpose of the present invention is to provide a pneumatic nail gun nail limiting and pressing device which has a simple structure, is safe and reliable, can effectively limit the flipping and deviation of nails without tools, increases the firing stability of nails, and prevents the pneumatic nail gun from getting stuck.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a pneumatic nail gun nail limiting and pressing device, comprising: a nail guide groove and a gun nozzle installed and fixed on the nail guide groove, characterized in that: a gun nozzle nail guide column is provided in the gun nozzle, and the gun nozzle nail guide column is correspondingly connected to the nail entry port of the nail guide groove, and a pair of hinged nail guide plates are provided on the nail guide groove, and the nail guide plates are located between the nail guide groove and the gun nozzle nail guide column, and the nail guide plates extend from the nail guide groove to the gun nozzle through the nail entry port to form a V-shaped opening, and one end of the nail guide plate located in the nail guide groove is flush with the nail guide plane of the nail guide groove; the symmetry planes of the paired nail guide plates coincide with the symmetry planes of the guide groove and the nail feeding groove of the gun nozzle nail guide column, respectively.

[0006] Preferably, a guiding slope is provided on one side of the nail guide plate corresponding to the gun nozzle nail guide column.

[0007] Preferably, a spring is provided between the pair of nail guide plates, and the spring keeps the pair of nail guide plates in a V-shaped open state and close to the nail entry wall of the gun muzzle.

[0008] Beneficial Effects

[0009] The structure of the present invention adopts a structural form of adding a pair of movable nail guide pieces in the nail entry of the nail guide groove between the nail feeding entrance and the gun nozzle, so that the nail entry of the pneumatic nail gun is provided with anti-stuck nail protection. When short nails are used, the guide pieces in the open state can be used to guide and convey; when long nails are used, the nail feet of the long nails can overcome the spring force of the guide pieces to close the guide pieces, which will not affect the conveyance of the long nails, thereby limiting the flipping and deviation of the gun nails, increasing the stability of the gun nail firing, and preventing the pneumatic nail gun from getting stuck.

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The implementation of the present invention is described in detail below with reference to specific drawings and embodiments.

[0018] A pneumatic nail gun nail limiting and pressing device comprises: a nail guide groove 1 and a gun nozzle 3 installed and fixed on the nail guide groove 1, characterized in that: a gun nozzle nail guide column 2 is arranged in the gun nozzle 3, and the gun nozzle nail guide column 2 is correspondingly connected to the nail entry of the nail guide groove 1, and a pair of hinged nail guide plates 5 are arranged on the nail guide groove 1, and the nail guide plates 5 are located between the nail guide groove 1 and the gun nozzle nail guide column 2. The nail guide plates 5 pass through the nail entry and extend from the nail guide groove 1 to the gun nozzle 3 in a V-shaped opening shape, and one end of the nail guide plates 5 located in the nail guide groove 1 is flush with the nail guide plane of the nail guide groove 1; the symmetry planes of the paired nail guide plates 5 coincide with the symmetry planes of the nail guide groove 1 and the nail feeding groove of the gun nozzle nail guide column 2 respectively.

[0019] Preferably, a guiding slope 31 is provided on one side of the nail guide plate 5 corresponding to the gun nozzle nail guide column 2 .

[0020] Preferably, a spring 4 is provided between the pair of nail guide plates 5 , and the spring 4 keeps the pair of nail guide plates 5 in a V-shaped open state and close to the nail entry wall of the gun nozzle 3 .

[0021] In actual application, the paired nail guide plates 5 open in a V shape under the action of the spring force of the spring 4, and are flush with the nail feeding entrance and the nail guide plane of the nail guide groove 1. The coding nails 6 pass through the nail entrance of the nail guide groove 1 under the guidance of the nail pushing plate 7 and enter the corresponding position of the gun nozzle guide nail column 2, and the coding nails 6 are snap-locked and positioned on the gun nozzle guide nail column 2.

[0022] like Figure 3 As shown, when the code nail 6 used in the nail gun is a long nail, the length of the nail foot is sufficient to buckle the nail guide plate 5 on the inner side of the code nail 6, and the code nail 6 overcomes the spring force of the spring 4 to close the paired nail guide plates 5. At this time, the length of the code nail is sufficient to pass through the gun nozzle guide nail column 2 smoothly, and the delivery and firing of the nail pusher plate 7 will not cause flipping, deviation, and other nail jamming phenomena in the gun nozzle guide nail column 2.

[0023] like Figure 4 As shown, when the code nails 6 used in the nail gun are short nails, the nail feet are insufficiently long, and the spring force of the spring 4 fully opens the paired nail guide plates 5 without resistance. The nail guide plates 5 are pressed against the entrance wall of the gun nozzle 3 and fill the gap at the nail entrance of the nail guide groove 1. At this time, the nail guide plates 5 are pressed against the end of the nail guide plates 5 under the guidance of the guide slope 31, and smoothly pass through the gap at the nail entrance of the guide groove 1 under the guidance of the nail guide plates 5. The delivery and firing of the nail push plates 7 will not cause nail jamming such as flipping and deflection in the gun nozzle guide nail column 2.

[0024] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
