Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a nail gun, particularly to a nail ejection structure for a nail gun. Background Technology

[0002] A nail gun mainly consists of a gun body, cylinder, switching assembly, piston, firing pin, firing pin locking device, nail nozzle, and nail magazine. Nails are placed in the nail magazine of the nail gun. The nails in the nail magazine enter the nail nozzle. After the gas in the cylinder is compressed, the pressure inside the cylinder is greater than the atmospheric pressure. When the firing pin locking device is unlocked, the piston is driven by the high-pressure gas to move the firing pin. The firing pin enters the nail nozzle and strikes the first nail in the nail nozzle, shooting the nail out from the nail outlet of the nail nozzle, thus realizing nail shooting. When the firing pin is locked again by the locking device, the second nail moves upward and becomes the first nail.

[0003] During the manufacturing process of a nail gun, the tip of the nail rests against the nozzle for positioning. However, in actual nailing, the nail struck by the firing pin may become stuck at the front of the nail ejection groove. Because adjacent nails are in close contact, and the ejector mechanism in the nail magazine constantly pushes the nail upwards, once a nail jams, it is difficult for the stuck nail to move within the ejection groove. The nail gun must be disassembled, along with the nozzle and nail magazine, to remove the stuck nail and restore the gun's operation. This makes removing a jammed nail from a nail gun very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a nail ejection structure for a nail gun. The technical problem this invention aims to solve is: how to facilitate nail removal when nails become stuck during the nail-shooting process of a nail gun.

[0005] The objective of this invention can be achieved through the following technical solution: a nail ejection structure for a nail gun, the nail gun including a nail magazine and a nail ejection nozzle disposed on the nail magazine, the nail ejection nozzle having a nail ejection groove, the nail magazine having a nail storage groove and a top nail structure for moving nails from the nail storage groove into the nail ejection groove, a cover plate being disposed above the nail ejection nozzle, the cover plate including a slide rail, the nail gun also including a firing pin for nailing, the firing pin reciprocating within the slide rail, characterized in that the nail ejection nozzle is provided with a plurality of locking blocks, the locking blocks forming locking grooves within the nail ejection groove for restricting nail movement, and the front end of the nail ejection groove also having a clearance gap for creating a gap between the front end of the nail and the front end of the nail ejection groove.

[0006] The working principle of this solution is as follows: Several nails are placed in the nail magazine of the nail gun. The nail magazine has a top nail structure, and the nail nozzle has a nail ejection groove. The top nail in the nail magazine is pushed into the slide of the cover plate. The nail ejection groove of the nail nozzle also has several locking blocks. The locking blocks form a locking groove to lock the tail of the nail. The locking groove is used to position the nail in the nail ejection groove. The clearance at the front end of the nail ejection groove ensures that there is a gap between the front end of the nail in the nail ejection groove and the nail ejection groove. The firing pin slides in the slide, striking the nail in the slide. When the nail in the slide engages in the nail ejection slot, the nail is locked in place with either the slide or the ejection slot. When the nail is locked in place with the slide, it can be directly removed from the slide. When the nail is locked in place with the nail ejection slot, the engagement point is located in the clearance gap of the ejection slot. Since the nail in the ejection slot no longer abuts against the locked nail, the locked nail has a larger adjustment range, making it easy to remove from the ejection slot. The main design feature of this solution is that the engagement slot and clearance gap in the ejection slot ensure that the nail in the ejection slot is located at the rear end of the ejection slot and that there is a gap between the nail and the front end of the ejection slot, making it easier to remove the nail locked in the ejection slot and making the nail gun more convenient to use.

[0007] In the nail ejection structure of the aforementioned nail gun, the ejection nozzle is provided with a clearance groove, which is connected to a clearance gap. The ejection nozzle is also provided with a guide surface, which is connected to the clearance groove. The clearance groove increases the adjustment space when the nail is engaged, and the guide surface facilitates easy removal of the nail from the ejection nozzle when the nail is stuck.

[0008] In the aforementioned nail ejection structure of the nail gun, the nail ejection nozzle is a split structure comprising a first nail ejection nozzle and a second nail ejection nozzle. The first and second nail ejection nozzles are joined together to form a nail ejection groove, and their upper surfaces are flush. This split structure facilitates the disassembly of the nail ejection nozzle and the removal of the engaged nail from the nail ejection groove.

[0009] In the nail ejection structure of the aforementioned nail gun, the first ejection nozzle is equipped with a retaining plate, and the second ejection nozzle is equipped with a clearance space. The retaining plate is located within the clearance space, and the retaining plate and the clearance space form a clearance groove. The guide surface is located on the second ejection nozzle. The retaining plate being located in the clearance groove prevents gaps from forming between the first and second ejection nozzles in the clearance gap, reducing the likelihood of the nail getting stuck. It also makes it easier to remove the nail if it does get stuck.

[0010] In the nail ejection structure of the aforementioned nail gun, the nail magazine is a split structure, including nail magazine one and nail magazine two. Nail magazine one and nail magazine two are joined together to form a nail storage slot. Both nail magazine one and nail magazine two are provided with locking strips for limiting the movement of nails. The locking strips correspond to locking blocks and are located within the nail storage slot. The locking strips facilitate the entry of nails from the nail storage slot into the nail ejection nozzle and their fixation in the locking slot of the nail ejection nozzle.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The main design of this solution is to make the nail in the nail outlet groove located at the rear end of the nail outlet groove and to create a gap between the nail and the front end of the nail outlet groove, so that the nail locked in the nail outlet groove can be easily removed, making the use of the nail gun more convenient.

[0013] 2. In this solution, the snap-fit ​​plate is located in the clearance groove to prevent the nail ejector nozzle 1 and nail ejector nozzle 2 from forming a gap in the clearance gap, thereby reducing the chance of the nail getting stuck and making it easier to remove the nail when it does get stuck.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] Example 1

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a pneumatic nail gun includes a housing 5 and a firing pin 4 that reciprocates on the housing 5 for nailing. The housing 5 also has a locking element 6 that locks or releases the firing pin 4. The locking element 6 has a locking hook 6a, and the firing pin 4 has a slot 4a on its side. In the locked state, the locking hook 6a is engaged in the slot 4a, keeping the firing pin 4 locked and unable to move. A first cylinder 7 and a second cylinder 8 are also provided inside the housing 5. A first piston 9 is located inside the first cylinder 7, and a piston rod 15 is connected to the first piston 9. A crank 14 is connected to the piston rod 15. A motor 12, located inside the housing 5, is connected to a gear reducer 13. The output shaft of the gear reducer 13 is connected to the crank 14. The rotational power of the motor 12 drives the first piston 9 to reciprocate linearly within the first cylinder 7. A second piston 10, which reciprocates, is located inside the second cylinder 8, and the firing pin 4 is fixed to the second piston 10. A removable battery 11 is also provided at the lower end of the grip portion of the housing 5. The battery 11 supplies power to the control board of the motor 12. A button is also provided at the lower end of the grip portion of the housing 5, which is also connected to the control board of the motor 12. When the button is pressed, the control board of the motor 12 controls the motor 12, which drives the first piston 9 to perform a compression stroke and a return stroke. A nail box 1 is provided at the front end of the housing 5. The nail box 1 has a top nail structure. Under the action of the top nail structure, the nail will automatically rise into the slide 3a of the cover plate 3 and the nail outlet slot 2e. After the first piston 9 completes the compression stroke, the unlocking mechanism will release the locking hook 6a from the slot 4a of the firing pin 4, so that both the firing pin 4 and the second piston 10 are in the unlocked state. The second piston 10 moves at high speed under high pressure, driving the firing pin 4 to strike the nail in front of the firing pin 4, completing one nailing action. Afterwards, the first piston 9 performs a return stroke. Under the action of negative pressure, the second piston returns to the locked position of the firing pin 4, and the locking hook 6a locks the firing pin 4 again, realizing continuous nailing.

[0025] Such as 4 and Figure 5As shown, the nail box 1 is a split structure, formed by splicing nail box 1b and nail box 1c. After splicing, nail box 1b and nail box 1c form a nail storage slot 1a for storing nails. Nail box 1b and nail box 1c are also provided with several locking strips 1d for limiting the nails. The locking strips 1d are located in the nail outlet slot 2e. The setting of multiple sets of locking strips 1d can accommodate nails of various lengths. The nail box 1 is provided with a nail outlet 2 at the top. The nail outlet 2 is a split structure, including a first nail outlet 2a and a second nail outlet 2c. The first nail outlet 2a and the second nail outlet 2c are spliced ​​together to form a nail outlet groove 2e. The upper surfaces of the first nail outlet 2a and the second nail outlet 2c are flush. The nail box 1 is provided with a top nail structure for moving the nails in the nail storage groove 1a into the nail outlet groove 2e. The top nail structure includes a nail outlet plate 1e. The nails in the nail storage groove 1a are located above the nail outlet plate 1e. The first nail ejector 2a and the second nail ejector 2c are also provided with several locking blocks 2g, or the locking blocks 2g on the first nail ejector 2a and the second nail ejector 2c form a locking groove 2f in the nail ejector groove 2e to restrict the movement of the nail. The locking groove 2f can accommodate nails of different lengths and types. The nails can be T-shaped, L-shaped, or other nails that can be fixedly locked in the locking blocks 2g or the locking groove 2f. In this example, the nail is T-shaped, and the nail 16 is positioned in the locking groove 2f. The position of the locking groove 2f corresponds to the position of the locking strip 1d. The front end of the nail ejector groove 2e is also provided with a clearance gap 2h. The first nail ejector 2a is provided with a locking plate 2b, and the second nail ejector 2c is provided with a clearance space 2d. The locking plate 2b is located in the clearance space 2d to form a clearance groove 2i. The second nail ejector 2c is also provided with a guide surface 2j.

[0026] like Figure 2 and Figure 5 As shown, a cover plate 3 is provided above the nail outlet 2, and a slide 3a is provided on the cover plate 3, in which the firing pin 4 moves back and forth.

[0027] The working principle of this solution is as follows: Several nails are placed in the nail magazine 1 of the nail gun. The nail magazine 1 is equipped with a top nail structure, and the nail nozzle is equipped with a nail delivery groove 2e. The topmost nail is pushed into the slide rail 3a of the cover plate 3. Several locking blocks 2g form a locking groove 2f to lock the tail of the nail. The locking groove 2f is used to position the nail in the nail outlet groove 2e. The clearance gap 2h at the front end of the nail outlet groove 2e creates a gap between the front end of the nail in the nail outlet groove 2e and the nail outlet groove 2e. The clearance groove 2i increases the distance between the front end of the nail in the nail outlet groove 2e and the end of the nail outlet groove 2e. The firing pin 4 slides in the slide rail 3a and strikes the nail in the slide rail 3a. When the nail in the slide rail 3a is locked in the nail outlet groove 2e, the nail is locked with the slide rail 3a or the nail outlet groove 2e. When the nail is locked with the slide rail 3a, the nail can be directly removed from the slide rail 3a. When the nail is locked in the nail outlet groove 2e, the locking point of the nail is located in the nail outlet groove 2e. In the clearance gap 2h, because the nail in the nail outlet groove 2e no longer abuts against the engaged nail, and the clearance gap 2h provides adjustment space for the engaged nail, while the clearance groove 2i also increases the adjustment hole space for the engaged nail, the engaged nail is easily removed from the nail outlet groove 2e. The main design of this scheme is to use the engagement groove 2f in the nail outlet groove 2e and the clearance gap 2h to ensure that the nail in the nail outlet groove 2e is located at the rear end of the nail outlet groove 2e and that there is a gap between the nail and the front end of the nail outlet groove 2e. This makes it easier to adjust and remove the nail engaged in the nail outlet groove 2e, making the use of the nail gun more convenient.
