Definitions

  • the invention relates to a fastener striking tool, in particular to an electric gas spring nail gun, belonging to the technical field of electric tools.
  • the compressed air causes the piston to drive the striker released by the drive wheel to move quickly to complete the nailing action. After that, the driving wheel enters the lifting meshing state again, and the next nailing cycle is performed. Since the energy source comes from electric energy, it has good control performance and is relatively safe.
  • the purpose of the present invention is to provide a fastener striking tool with a simple structure and avoiding jamming in view of the above-mentioned shortcomings of the prior art, thereby ensuring convenient and safe use.
  • the basic technical solution of the fastener striking tool of the present invention is: an energy storage mechanism composed of a cylinder in a housing and a piston, the piston is connected to a firing pin extending to the gun mouth, and one of the cylinders A handle with a battery pack is arranged on the side, a nail magazine is arranged on one side of the gun mouth, and a lifting mechanism is arranged between the handle and the nail magazine;
  • the lifting mechanism includes strikers with meshing teeth spaced apart in the length direction, and driving wheels spaced and meshing cylindrically spaced on a predetermined arc length, and the driving wheels are in transmission connection with the electric motor provided by the battery pack;
  • the driving wheel extends radially from the opposite side of the predetermined arc length, and the side surface of the striker opposite to the meshing tooth has a leading protruding pin that can be engaged with the stop finger, and the stop finger enters and Before the meshing teeth are lifted and meshed, turn to the meshing shifting position in front of the leading protruding pin; when the meshing cylinder enters and meshing with the meshing tooth lifting, the shifting finger is turned to toggle the leading protruding pin so that the meshing tooth is in the meshing cylinder The meshing position.
  • a further improvement of the present invention is that the driving wheel has two symmetrical wheels, and the engagement cylinder is supported between the two symmetrical wheels.
  • a further improvement of the present invention is that the opposite sides of the two symmetrical wheels with the predetermined arc length respectively extend radially from the gear fingers, and the two sides of the striker opposite to the meshing teeth have cylindrical advances that can mesh with the corresponding gear fingers. Convex pin.
  • a further improvement of the present invention is that the shift finger has a uniform-speed lifting curve flange which forms a cam pair with the advance convex pin.
  • a further improvement of the present invention is that the two ends of the uniform lifting curve flange respectively have transitional arcs.
  • FIG. 1 is a schematic diagram of a three-dimensional structure of Embodiment 1 of the present invention.
  • FIG. 2 is a schematic cross-sectional view of the structure of the embodiment in FIG. 1.
  • FIG. 3 is a schematic diagram of the three-dimensional structure of the lifting mechanism in the embodiment of FIG. 1.
  • FIG. 4 is a schematic diagram of the structure of the initial position of the lifting mechanism in FIG. 3.
  • Fig. 5 is a schematic diagram of the structure of the end position of the lifting mechanism of Fig. 3.
  • Fig. 6 is a schematic diagram of a prior art meshing interference structure.
  • the basic structure of the fastener striking tool of this embodiment is shown in Figures 1 and 2.
  • the rear end of the housing 1 is equipped with an energy storage mechanism 2 composed of a cylinder 2-2 and a piston 2-1, and the piston 2-1 It is fixedly connected with the firing pin 4 extending to the gun nozzle 3.
  • the lower side of the cylinder 2-2 is provided with a handle 5 with a battery pack 5-1.
  • the lower side of the gun nozzle 3 is provided with a nail magazine 6 for arranging nails.
  • the upper side of the handle 5 and the nail magazine 6 is provided.
  • the lifting mechanism 7 and the motor 8 and the reduction transmission mechanism 8-1 located at the lower part.
  • the lifting mechanism is shown in Fig. 3, which contains strikers 4 with meshing teeth spaced apart in the length direction, and a driving wheel 9 engaged with it.
  • the driving wheel 9 is supported by two symmetrical wheels 9-1 and between the two symmetrical wheels.
  • the meshing cylinders 9-2 spaced apart on a predetermined arc length are formed, and the driving wheel 9 is drivingly connected to the motor 8 provided by the battery pack 5-1.
  • the two symmetrical wheels of the driving wheel 9 are radially extended from the opposite sides of the predetermined arc length to the finger 9-3, and the two surfaces of the striker 4 opposite to the meshing teeth have cylindrical advance projections that can mesh with the corresponding finger 9-3. Pin 4-1.
  • the symmetrical wheel structure of this embodiment not only changes the prior art cantilever engagement cylinder into a two-end support structure, but also forms a symmetrical engagement structure of the stop fingers and the leading pins on both sides on this basis, which has stronger bearing capacity, The transmission is more stable.
  • the shift finger 9-3 has a uniform lifting curve flange C that forms a cam pair with the advance convex pin 4-1, and both ends of the uniform lifting curve flange C are respectively provided with transitional arcs, thereby ensuring the smooth and reliable lifting movement.
  • the shifting finger 9-3 turns to the engagement shifting position in front of the leading convex pin 4-1, even if it encounters a staple, etc. The reason causes the firing pin to deviate from the initial position.
  • the stop finger 9-3 can play a blocking role when it initially engages with the leading pin 4-1, effectively preventing the firing pin from losing control and ensuring safety, and then driving the firing pin to engage Cylinder 9-2 can enter the normal lifting engagement position of the meshing teeth, that is, when the shifting finger 9-3 enters the meshing cylinder 9-2 to lift the meshing teeth, it will turn to move the leading convex pin 4-1 to make the meshing teeth in The meshing position with the meshing cylinder, so as to avoid the jam as shown in FIG. 6. After that, the driving wheel continues to rotate, and the meshing cylinder and the meshing teeth complete the lifting and meshing until the meshing and disengaging position shown in Figure 5 is reached, and the striker will suddenly release the nail.
  • the present invention can also have other changes.
  • the stop finger in order to make the protruding pin on the striker only receive the force along the movement direction of the striker during the rotation of the driving wheel, the stop finger can also be designed as a lifting flange with other curves. All technical solutions formed by equivalent replacements or equivalent transformations fall within the protection scope of the present invention.
