Description
Technical Field
[0001] The utility model relates to the technical field of nail guns, in particular to a nail gun. Background Art
[0002] As is well known, the nail gun is often called a nail gun because its appearance and principle are similar to those of a pistol. It is a fastening tool that uses blank cartridges, gas, or compressed air as power to drive nails into a building body. Since the firing steps of the nail gun are simple and only need to turn on the switch or pull the trigger to fire, it is also widely used. For example, a construction engineering nail gun disclosed in the Chinese utility model patent with the authorization publication number CN219293876U triggers by clicking on a control button to control an electronically controlled air valve, so that the gas inside the air pipe enters the air cylinder, drives the air cylinder to move to the right, and then pushes the movement of the firing pin rod to achieve the point impact trigger of the nail, and completes the fixing work of the nail. Since this needs to be used frequently and repeatedly, it is very easy to have jamming and misfiring phenomena, so the stability and safety required by users cannot be satisfied, and thus it cannot meet the requirements.

However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0034] Embodiment 1: Refer to Figures 1 to 9, A nail gun, comprising a housing 1. Inside the housing 1, a base 2 is provided. Inside the base 2, a reset member 3 is provided. On the end face of the base 2, a limit housing 4 is fixed. Inside the limit housing 4, a sliding housing 5 is provided. Inside the sliding housing 5, a firing pin 6 that moves back and forth is provided. On the end face of the limit housing 4, a reset telescopic sleeve 7 is provided. On the end face of the reset telescopic sleeve 7, a nail head 8 is provided. On the end face of the housing 1, a sliding sleeve 9 is provided. The sliding sleeve 9 slides on the housing 1, and a driving portion 91 is provided on the sliding sleeve 9. A groove is formed between the reset telescopic sleeve 7 and the nail head 8, and the driving portion 91 is located in the groove. During the back-and-forth movement of the sliding sleeve 9, the reset telescopic sleeve 7 and the nail head 8 are driven to move. The firing pin 6 is connected to the base 2 through the reset member 3. This is beneficial for realizing the reset of the firing pin 6, and a firing structure 10 is formed between the firing pin 6 and the base 2. Through the firing structure 10, the firing pin 6 can be prompted to be fired, avoiding accidental firing and improving the safety of use. The firing pin 6 will also operate more smoothly and stably without jamming. Further explanation, an exhaust valve is provided on the nail head 8. This is beneficial for exhausting air through the nail head 8 and is more beneficial for the movement of the firing pin 6.
[0035] When the present utility model is in use, a nail (nail gun) is installed on the nail head 8, and then the sliding sleeve 9 is slid towards one side of the housing 1. At this time, the sliding sleeve 9 will drive the reset telescopic sleeve 7 and the nail head 8 to move towards one side of the housing 1. Next, the reset telescopic sleeve 7 will drive the sliding housing 5 to also slide towards one side of the housing 1. Furthermore, the sliding housing 5 will drive the firing pin 6 to move towards one side of the housing 1. In this way, the firing pin 6 will compress the reset member 3 until the firing structure 10 is triggered. Then, the firing pin 6 will move towards the side away from the housing 1. The firing pin 6 is used to achieve the point impact trigger of the nail gun, and the fixing work of the nail gun is completed.
[0036] Embodiment 2: It can be described on the basis of Embodiment 1 that, for example Figures 1 to 9As shown in the figure, the firing structure 10 includes a ratchet wheel 101 provided on the firing pin 6, and a binding sleeve 102 is provided on the ratchet wheel 101. In the original state, the front end of the ratchet wheel 101 is in an unfolded state. At this time, the outer diameter of the front end of the ratchet wheel 101 is greater than the inner diameter of the sliding shell 5, so that the front end face of the ratchet wheel 101 abuts against the rear end face of the sliding shell 5, which can prevent the firing pin 6 from moving forward. A starting portion 103 is provided on the inner side wall of the front end of the base 2. When the starting portion 103 contacts the front end of the ratchet wheel 101, it forces the front end of the ratchet wheel 101 to converge and contract towards the inner diameter, thereby making the outer diameter of the ratchet wheel 101 smaller than the inner diameter of the sliding shell 5, which ultimately facilitates the forward sliding of the firing pin 6. In the original state, the front end of the ratchet wheel 101 is in an unfolded state. At this time, the outer diameter of the front end of the ratchet wheel 101 is greater than the inner diameter of the sliding shell 5, so that the front end face of the ratchet wheel 101 abuts against the rear end face of the sliding shell 5, which can prevent the firing pin 6 from moving forward. When in use, only need to manually slide the sliding sleeve 9 towards the outer shell 1. At this time, the sliding sleeve 9 will drive the reset telescopic sleeve 7 and the nail head 8 towards the outer shell 1. Next, the reset telescopic sleeve 7 will drive the sliding shell 5 to also slide towards the outer shell 1. Then the sliding shell 5 will drive the firing pin 6 to move towards the outer shell 1. In this way, the firing pin 6 will compress the reset member 3. Since the ratchet wheel 101 is bundled on the firing pin 6 by the binding sleeve 102, when the starting portion 103 contacts the front end of the ratchet wheel 101, it forces the front end of the ratchet wheel 101 to converge and contract towards the inner diameter, thereby making the outer diameter of the ratchet wheel 101 smaller than the inner diameter of the sliding shell 5. Ultimately, it is beneficial for the firing pin 6 to slide forward, and the firing pin 6 will move away from the outer shell 1. The firing pin 6 is used to achieve the point impact trigger of the nail 81 to complete the fixing work of the nail. Through this setting, it is beneficial to avoid the danger caused by misoperation. Only by sliding the sliding sleeve 9 towards the outer shell 1 to prompt the rear part of the firing pin 6 to move into the base 2, so that the starting portion 103 and the front end of the ratchet wheel 101 are fully matched, can the front end of the ratchet wheel 101 be forced to converge and contract towards the inner diameter, so that it can be triggered, making the use safer and more reliable, and the movement of the firing pin 6 is smoother in the later stage.
[0037] As Figures 1 to 9 shown, further explanation is that the ratchet wheel 101 includes at least two mounting grooves provided on the firing pin 6. A corresponding tilting block is installed in each mounting groove. All the tilting blocks are sleeved on the firing pin 6 by the binding sleeve 102, and the tilting blocks can perform lever movement with the binding sleeve 102 as the fulcrum. This is beneficial to make the front end of the ratchet wheel 101 force the front end of the ratchet wheel 101 to converge and contract towards the inner diameter, thereby making the outer diameter of the ratchet wheel 101 smaller than the inner diameter of the sliding shell 5. Ultimately, it is beneficial for the firing pin 6 to slide forward, and the firing pin 6 will move away from the outer shell 1. The firing pin 6 is used to achieve the point impact trigger of the nail to complete the fixing work of the nail. In this embodiment, both the mounting grooves and the tilting blocks are three. The three mounting grooves and tilting blocks are evenly distributed on the firing pin 6. This setting is reasonable and convenient to implement.
[0038] As Figures 1 to 9 shown, for further illustration, the starting part 103 adopts an inner inclined surface, while the tilting block adopts an outer inclined surface on its front outer surface. When the inner inclined surface is in full contact with the outer inclined surface, the tilting block can move downward, ultimately making the outer diameter of the ratchet wheel 101 smaller than the inner diameter of the sliding shell 5, which is beneficial for the forward sliding start of the firing pin 6. When the outer inclined surfaces of all the tilting blocks lose external pressure, the front part of the ratchet wheel 101 will expand, and the outer diameter of the front end of the ratchet wheel 101 is larger than the inner diameter of the sliding shell 5, causing the front end surface of the ratchet wheel 101 to abut against the rear end surface of the sliding shell 5, ultimately preventing the forward movement of the firing pin 6 from being started and preventing accidental triggering.
[0039] Embodiment Three: It can be described based on Embodiment One or Embodiment Two. As Figures 1 to 9 shown, a limiting hole 41 is provided on the limiting shell 4, a restricting hole 51 is provided on the sliding shell 5, and a limiting pin 61 is provided on the firing pin 6. The limiting pin 61 moves back and forth in the limiting hole 41 and the restricting hole 51 simultaneously. In this way, the limiting hole 41 and the restricting hole 51 can simultaneously restrict the movement of the limiting pin 61, which is beneficial for the movement of the firing pin 6.
[0040] Embodiment Four: It can be described based on Embodiment One or Embodiment Two or Embodiment Three. As Figures 1 to 9 shown, the reset telescopic sleeve 7 includes a connecting sleeve 71 arranged between the nail head 8 of the nail gun and the limiting shell 4. One end of the connecting sleeve 71 is threadedly connected to the nail head 8 of the nail gun. This setting is convenient for installation and disassembly and is also beneficial for moving together. The other end of the connecting sleeve 71 is located between the limiting shell 4 and the sliding shell 5, and a return spring 72 is provided on the other end of the connecting sleeve 71. The return spring 72 is sleeved on the sliding shell 5. This is beneficial for promoting the return of the connecting sleeve 71 through the return spring 72.
[0041] Embodiment Five: It can be described based on Embodiment One or Embodiment Two or Embodiment Three or Embodiment Four. As Figures 1 to 9 shown, a limiting sleeve 11 is provided between the limiting shell 4 and the outer shell 1. The limiting sleeve 11 is more beneficial for fixing the limiting shell 4 inside the outer shell 1.
[0042] Embodiment Six: It can be described based on Embodiment One or Embodiment Two or Embodiment Three or Embodiment Four or Embodiment Five. As Figures 1 to 9 shown, the outer shell 1 is in the shape of a gunstock. This setting is more beneficial for the user to hold and use.
[0043] Embodiment Seven: It can be described based on Embodiment One or Embodiment Two or Embodiment Three or Embodiment Four or Embodiment Five or Embodiment Six. As Figures 1 to 9 shown, the reset part 3 adopts a reset spring, which has a wide source and is convenient for implementation.
[0044] The standard parts used in this application document can all be purchased from the market. For the specific connection methods of each part, conventional means such as bolts and rivets that are mature in the prior art are adopted, and no specific description will be made here.
