Description

Technical Field

[0001] The utility model relates to an electric wood nail gun, belonging to the technical field of electric tools. Background Art

[0002] There are many types of fastener drivers currently available on the market, which are mainly used to drive fasteners into workpieces. Usually a striker is used to hit the fastener. There is physical contact and friction in the process of driving the striker. In order to reduce wear and extend the life of the striker and mating parts, grease is added to the contact part to achieve the purpose of reducing mechanical wear. As the use time increases, grease leaks, the grease attached to the striker and the mating part decreases, and the friction reduction effect decreases, which can easily lead to increased wear of the striker and the mating part, resulting in premature failure. Due to the movement of the striker, grease leakage during use is difficult to avoid. How to ensure that the striker parts of the entire machine are effectively lubricated during long-term operation is an issue that urgently needs to be improved. Utility Model Content

[0003] The utility model aims to provide an electric wood nail gun to solve the problem that the lubrication effect of the striker and its meshing contact part deteriorates and the wear increases during long-term work of the existing tools, so as to ensure the long-term effective lubrication of the striker and improve the working efficiency.

[0004] In order to achieve the above purpose, the utility model provides an electric wood nail gun, including a casing, a driving component inside the casing that engages with a firing pin, a refueling interface on the casing, the refueling interface is located at the engaging portion between the firing pin and the driving component, and the surface of the refueling interface is detachably connected to a seal.

[0005] Furthermore, the sealing member is a circular sealing cover, and the sealing cover has a thread that is connected to the refueling interface. The outer periphery of the sealing cover is a regular polygon, and the middle of the cover body has a boss extending downward, and the outer surface of the boss is formed with a thread that is connected to the refueling interface, and the upper surface of the cover body is provided with a groove.

[0006] Furthermore, the sealing member is a strip-shaped sealing cover, which is fixed to the housing at the refueling interface by screws. Both ends of the sealing cover are provided with sunken screw holes matched with the screws, and the middle of the sealing cover has a hand-held rib protruding outward. The sealing cover is made of metal, plastic or rubber.

[0007] When in use, the seal can be quickly opened to expose the meshing portion of the driving component that cooperates with the striker, and the grease can be observed from the refueling interface to see whether there is enough grease, and grease can be added to the interface.

[0008] The utility model has a simple structure and is easy to use, and has the beneficial effects of: the interface for adding grease can be opened quickly and conveniently during maintenance, so as to achieve the purpose of quickly adding grease, thereby saving a lot of time spent on maintenance and improving work efficiency.

[0019] The striker 2 of the existing fastener driver 1 contacts the driving component 3 to obtain the driving force. In order to reduce wear, lubricating grease needs to be added here. During use, the lubricating grease is easy to leak, which may cause the striker 2 and the driving component 3 to wear more and fail prematurely. To improve this phenomenon, the structure of this embodiment is as follows Figure 1-5As shown, an electric wood nail gun includes a housing 5, a driving component 3 meshed with a striker 2 inside the housing 5, a refueling interface 7 on the housing 5, and the refueling interface 7 is located at the meshing portion of the striker 2 and the driving component 3. The surface of the refueling interface 7 is detachably connected to a seal. The seal is a circular sealing cover 4, and the outer periphery of the cover body 4-1 of the sealing cover 4 is a regular polygon, which is easy to unscrew. There is a boss 4-2 extending downward in the middle of the cover body, and the outer surface of the boss 4-2 is formed with a thread that cooperates with the refueling interface 7. A groove 4-3 is provided on the upper surface of the cover body 4-1. After the sealing cover 4 is opened, the driving component 3 can be directly observed through the refueling interface 7 located on the housing 5. Embodiment 2

[0020] The structure of this embodiment is roughly the same as that of the first embodiment, except that Figure 6-Figure 9 As shown, the sealing member is a long strip sealing cover, which is fixed to the housing 5 at the refueling interface 7 by screws 6. Both ends of the sealing cover 4 are provided with sunken screw holes 4-4 that cooperate with the screws, and the middle of the sealing cover 4 is provided with a hand-held rib 4-5 protruding outwards for easy access. The sealing cover is made of metal, plastic or rubber.

[0021] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
