[0002] The energy storage components of existing nail guns generally include flywheel type, spring type, medium-pressure (specifically, about 3 atmospheres) piston type cylinders, and high-pressure plunger type cylinder energy storage devices.

[0003] Due to the small energy storage capacity of flywheel type and spring type, the product is heavy and large in size, and currently it is gradually replaced by nail guns with medium-pressure piston type cylinders and high-pressure plunger type cylinder energy storage components.

[0004] However, for existing nail guns, whether it is a medium-pressure piston type cylinder or a high-pressure plunger type cylinder, they are all installed in series on the top of the firing pin. The overall height of the nail gun includes not only the height in the moving direction of the firing pin but also the height of the cylinder.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 12。A nail gun provided by an embodiment of the present application includes: a housing 11, a striker assembly 32, an energy storage device 81, a power source 85, and a traction and steering device 83; wherein, the striker assembly 32 is movably disposed within the housing 11; the energy storage device 81 is disposed within the housing 11; the energy storage device 81 includes an energy storage cylinder 27 and a piston 29 disposed through the energy storage cylinder 27; a seal is disposed between the piston 29 and the energy storage cylinder 27, and the seal can be disposed on the piston 29, and during the reciprocating movement of the piston 29, the seal moves together with the piston 29; the seal can also be fixedly disposed within the energy storage cylinder 27, and during the reciprocating movement of the piston 29, the seal does not move together with the piston 29, and at this time the piston 29 can be understood in the form of a plunger; the piston 29 is connected to the striker assembly 32 through the traction and steering device 83; the power source 85 is configured to drive the striker assembly 32 to move in a first direction, so that the striker assembly 32 can drive the piston 29 to move in a second direction and compress the gas within the energy storage cylinder 27 in the energy storage mode; and further, in the striking mode, the piston 29 moves in a direction opposite to the second direction under the action of the compressed gas within the energy storage cylinder 27, and drives the striker assembly 32 to move in a direction opposite to the first direction to strike a nail 31; the first direction and the second direction are arranged at an angle.

[0037] It can be seen from the above technical solutions that: the nail gun 1 according to the embodiment of the present application is provided with a housing 11, a striker assembly 32, an energy storage device 81, a power source 85, and a traction and steering device 83; the power source 85 is configured to drive the striker assembly 32 to move in a first direction, so that the striker assembly 32 can drive the piston 29 to move in a second direction and compress the gas within the energy storage cylinder 27; and further, the piston 29 moves in a direction opposite to the second direction under the action of the compressed gas within the energy storage cylinder 27, and drives the striker assembly 32 to move in a direction opposite to the first direction to strike a nail 31; the first direction and the second direction are arranged at an angle. Thus, the moving direction of the striker assembly 32 of the nail gun according to the embodiment of the present application is arranged at an angle with the moving direction of the piston 29, so that the energy storage device 81 does not occupy the height of the housing 11 along the moving direction of the striker assembly 32; and further, the overall height of the nail gun is reduced. In the prior art, when the energy storage device 81 is serially installed on the top of the striker assembly 32, it will cause the height of the nail gun along the moving direction of the striker assembly 32 to increase due to the volume and movement of the energy storage device 81 itself. Therefore, the overall height of the nail gun according to the embodiment of the present application is low, and further, construction can be carried out in a narrow space.

[0038] In the present embodiment, the housing 11 is generally of a hollow structure. The hollow part forms a cavity. For example, Figure 1As shown, the machine housing 11 includes a connected housing body and a gun head 13. The housing body includes a handle portion 15 for gripping, a main body portion 17 connected to the handle portion 15 to perform the action of driving a nail 31, and a switch portion 19 for controlling the operation of the main body portion 17. A U-shaped is formed between the handle portion 15 and the main body portion 17 to facilitate the operator's gripping. The switch portion 19 includes a trigger 21 disposed between the handle portion 15 and the main body portion 17. The trigger 21 is used to open and close the power source 85. The power source 85 includes a motor 23. The trigger 21 is used to control the opening of the motor 23.

[0039] In the present embodiment, the striker assembly 32 is movably disposed within the machine housing 11. Specifically, the striker assembly 32 movably penetrates through the gun head 13. Further, the nail gun 1 of the present application embodiment further includes: a nail magazine 41 for accommodating the nails 31. Specifically, the nail magazine 41 includes a housing, a nail feeder movable relative to the housing, and an elastic member. The nail feeder is driven by the elastic member to continuously convey the nails 31 into the gun head 13, so that the striker assembly 32 can strike the nails 31 conveyed to the gun head 13 out of the gun head 13. For example, as Figure 1 shown, the nail magazine 41 is located below the main body portion 17 and is connected to the gun head 13. Further, as Figure 4 shown, the nail magazine 41 has an opening provided on a side close to the gun head 13, so that the nail feeder can continuously convey the nails 31 into the gun head 13 through the opening.

[0040] In the present embodiment, the energy storage device 81 is disposed within the machine housing 11. Specifically, the energy storage device 81 includes an energy storage cylinder 27 and a piston 29 penetrating through the energy storage cylinder 27. For example, as shown in the figure, the energy storage device 81 is disposed within the main body portion 17. And the piston 29 penetrates through the energy storage cylinder 27 through the right end of the energy storage cylinder 27. Further, the piston 29 is connected to the striker assembly 32 through a traction steering device 83. Thus, the piston 29 and the striker assembly 32 can form a linkage. That is, the movement of the piston 29 can drive the movement of the striker assembly 32. The movement of the striker assembly 32 can drive the movement of the piston 29.

[0041] In the present embodiment, the power source 85 is used to drive the striker assembly 32 to move in a first direction, so that the striker assembly 32 can drive the piston 29 to move in a second direction and compress the gas in the energy storage cylinder 27 in the energy storage mode; and then in the striking mode, the piston 29 moves in a direction opposite to the second direction under the action of the compressed gas in the energy storage cylinder 27, and drives the striker assembly 32 to move in a direction opposite to the first direction to strike the nail 31. As Figure 3 、 Figure 4 shown, in the energy storage mode, the power source 85 is used to drive the striker assembly 32 to move upward within the gun head 13. As Figure 3 、 Figure 4As shown, when the firing pin assembly 32 moves upward, the firing pin assembly 32 drives the piston 29 to move into the energy storage cylinder 27 through the traction steering device 83, thereby compressing the gas in the energy storage cylinder 27. When the firing pin assembly 32 moves upward to the highest point, the power source 85 stops driving the firing pin assembly 32 to complete energy storage. As Figure 5 , Figure 6 shown, in the striking mode, the power source 85 releases to drive the firing pin assembly 32, so that the compressed gas in the energy storage cylinder 27 can drive the piston 29 to move leftward, and thus the piston 29 drives the firing pin assembly 32 to move downward through the traction steering device 83, thereby striking the nail 31. As Figure 3 shown, the first direction is the vertically upward direction. The direction opposite to the first direction is the vertically downward direction. The second direction is the horizontally rightward direction. The direction opposite to the second direction is the horizontally leftward direction. Further, the first direction and the second direction are arranged at an angle. As Figure 1 shown, the overall height of the housing 11 is mainly determined by the height of the housing 11 near the gun head 13. And the firing pin assembly 32 is movably arranged in the gun head 13. Thus, by arranging the moving direction of the piston 29 and the moving direction of the firing pin assembly 32 at an angle, the height of the housing 11 near the gun head 13 is less increased or even not increased; thereby reducing the overall height of the housing 11 to enable construction in a narrow space. Preferably, for example, as Figure 3 shown, the first direction and the second direction are perpendicularly arranged. Thus, the movement of the piston 29 does not increase the height of the housing 11 near the gun head 13, making the overall height of the housing 11 reach the lowest. Further, the nail gun 1 has a length along the first direction. This length is not greater than 300 mm. Specifically, the nail gun 1 has a first outer end 87 and a second outer end 89 that are opposite to each other along the first direction. As Figure 1 shown, the first outer end 87 and the second outer end 89 are the top and bottom of the nail gun 1 near the gun head 13. Further, the distance between the first outer end 87 and the second outer end 89 is not greater than 300 mm.

[0042] Further, the nail magazine 41 has a longitudinal extension line, and this longitudinal extension line is arranged side by side with the energy storage device 81 and the power source 85 along the first direction. For example, as Figures 2 to 8As shown, the nail magazine 41, the energy storage device 81 and the power source 85 are arranged side by side in the vertical direction. And the nail magazine 41, the energy storage cylinder 27, the piston 29 and the power source 85 all extend in the horizontal direction. The piston 29 can move in the left and right direction in the energy storage cylinder 27. In this way, the energy storage device 81 in the nail gun described in the embodiment of the present application is no longer installed in series on the top of the striker assembly 32, but is arranged on one side of the moving direction of the striker assembly 32; thereby, the height dimension of the energy storage device 81 itself and the moving range of the piston 29 can overlap with the moving range of the striker assembly 32, thereby sharing the height space of the entire housing 11; thereby avoiding the volume of the energy storage device 81 itself and the movement of the piston 29 to increase the height space of the housing 11 near the gun head 13; thus reducing the overall height of the housing 11.

[0043] Furthermore, the energy storage device 81 is disposed between the power source 85 and the nail magazine 41. Specifically, the power source 85 also includes a reduction box 55 that is transmission-connected to the motor 23. Figure 5 As shown, the reduction box 55 is located on the left side of the motor 23. The energy storage device 81 is arranged between the reduction box 55 and the nail magazine 41. In this way, the traction wheel 47 in the traction steering device 83 can be arranged between the reduction box 55 and the energy storage cylinder 27, thereby making full use of the idle space between the reduction box 55 and the energy storage cylinder 27; reducing the volume of the nail gun; and making the structure of the nail gun more compact.

[0044] Furthermore, the striker assembly 32 includes a striker seat 33 and a striker body 34. Figure 4 , Figure 6 As shown, the firing pin seat 33 is disposed on one side of the main body 17 close to the gun head 13. The firing pin seat 33 is generally rectangular and extends up and down. Further, the firing pin body 34 is disposed on the firing pin seat 33. Specifically, the firing pin seat 33 has an inner cavity. The firing pin body 34 is fixedly disposed in the inner cavity. The fixing method may be screw fixing, bolt fixing, welding fixing, etc., which is not specified in this application. Further, as Figure 4 As shown, the striker body 34 is provided with a striker 25. Furthermore, the power source 85 is used to abut against the striker seat 33, thereby driving the striker seat 33 to move, so that the striker seat 33 can drive the striker body 34 to move along the first direction. Specifically, a lifting device 43 connected to the power source 85 is also provided in the housing 11. For example, Figure 5 As shown, the lifting device 43 is arranged on the side of the reduction box 55 close to the energy storage cylinder 27. And the lifting device 43 is located above the energy storage cylinder 27. Further, a stop surface 45 is arranged on one end of the striker seat 33 facing the nail magazine 41. For example, Figure 7 , Figure 8As shown, a stop surface 45 facing downward is provided at the top of the striker seat 33. The stop surface 45 is used to abut against the lifting device 43 so that the lifting device 43 can drive the striker seat 33 to move in the first direction. Specifically, the lifting device 43 includes a plurality of gears 57 meshing with each other in the up and down direction in sequence. The lowermost gear 57 is in transmission connection with the output shaft of the reduction gearbox 55. In this way, when the motor 23 is turned on, it can drive a plurality of gears 57 to rotate simultaneously. For example, as Figure 7 , Figure 8 shown, the lifting device 43 includes 3 gears 57 meshing with each other in the up and down direction in sequence. Further, protrusion portions 61 are provided on the end faces of the two upper gears 57 among the 3 gears 57 away from the reduction gearbox 55. The protrusion portions 61 are used to abut against the stop surface 45, and further drive the stop surface 45 to move in the first direction. More specifically, the protrusion portions 61 on the two gears 57 can abut against the stop surface 45 in sequence from bottom to top, so that the two gears 57 can drive the striker seat 33 to move upward in sequence.

[0045] Further, a guiding portion 35 is provided on the striker seat 33. Specifically, the guiding portion 35 is a guiding plate. The guiding plate protrudes radially from the side wall of the striker seat 33. For example, as Figure 7 , Figure 8 shown, there are two guiding portions 35. The two guiding portions 35 protrude radially from the opposite sides of the striker seat 33 respectively. Further, a guiding portion 37 is provided inside the housing 11. A guiding groove 39 is provided on the guiding portion 37. The guiding groove 39 is used for the guiding portion 35 to slide through, so as to guide the striker seat 33 to move in the first direction. For example, as Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, a guiding portion 37 is provided inside the main body. The guiding portion 37 is integrally strip-shaped. And the guiding portion 37 extends in the up and down direction. The guiding portion 35 is provided with a guiding groove 39 opening towards the striker seat 33. The guiding groove 39 extends in the up and down direction, so that the guiding groove 39 enables the guiding plate to move only along its extending direction, thereby ensuring that the striker seat 33 can move in the first direction and the direction opposite to the first direction. Even further, there are two guiding portions 37. Guiding grooves 39 are respectively provided on the two guiding portions 37. A guiding plate is slidably penetrated through each guiding groove 39. Further, the guiding portion 37 is arranged at an angle with the energy storage device 81. As Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, the guiding portion 37 is vertically arranged with the energy storage device 81.

[0046] Further, the traction and steering device 83 includes a traction wheel 47 and a traction member 49. For example, as Figure 3 , Figure 4 , Figure 5 ,Figure 6 As shown, the traction wheel 47 is arranged in the idle space between the energy storage cylinder 27 and the reduction gearbox 55. Further, as Figure 3 shown, there are two traction wheels 47 and two traction members 49 respectively. The two traction wheels 47 are parallel to the central axis of the over-striking needle body 34 and symmetric with respect to the plane in the second direction.

[0047] Further, the traction wheel 47 rotates around the wheel axis, and the wheel axis is located between the end face of the energy storage cylinder 27 facing away from the piston 29 and the striker 25 in the second direction. For example, as Figure 3 shown, the traction wheel 47 is located on the right side of the energy storage cylinder 27. And the traction wheel 47 is located on the left side of the striker 25.

[0048] Further, the traction wheel 47 rotates around the wheel axis, and the wheel axis is located between the central line of the energy storage cylinder 27 and the central line of the power source 85 in the first direction.

[0049] Further, the traction steering device 83 further includes a fixed shaft 51 arranged in the housing 11. A bearing 53 sleeved on the fixed shaft 51. The traction wheel 47 is sleeved outside the bearing 53. The traction wheel 47 can rotate relative to the fixed shaft 51. Specifically, the fixed shaft 51 is fixedly arranged in the housing 11. This fixing method can be screw fixing, bolt fixing, welding fixing and integral molding fixing, etc., which are not specified in this application. The bearing 53 can be a needle bearing 53, a roller bearing 53, etc. Further, the traction member 49 passes around the traction wheel 47 and changes the extension direction. And the two ends of the traction member 49 are respectively connected to the piston 29 and the striker seat 33. In this way, the acting force in one direction can be converted into the acting force in another direction through the traction member 49. Specifically, the traction member 49 can convert the horizontal acting force of the piston 29 into the vertical acting force of the striker assembly 32. Or the traction member 49 can convert the vertical acting force of the striker assembly 32 into the horizontal acting force of the piston 29. In this way, it is not necessary for the energy storage device 81 to be connected in series with the striker assembly 32, thereby reducing the overall height dimension of the housing 11. Further, the traction member 49 is made of a flexible and low elongation material, such as a belt, a steel wire rope, etc., so as to facilitate the steering of the force.

[0050] Further, a rod body 63 is arranged at one end of the piston 29 facing away from the energy storage cylinder 27. For example, as Figure 3 、 Figure 5 shown, the rod body 63 is perpendicularly arranged to the piston 29. Further, the two ends of the traction member 49 are respectively connected with a first traction part 65 and a second traction part 67. The first traction part 65 is connected with the guiding part 35. The second traction part 67 is connected with the rod body 63. In this way, the traction member 49 can be respectively connected with the striker seat 33 and the piston 29 through the first traction part 65 and the second traction part 67. Further, as Figure 9 、Figure 10 As shown, a first groove 69 is provided on the guide portion 35. The first traction portion 65 is a first hanging ear. The first hanging ear is embedded in the first groove 69. A second groove 71 is provided on the rod body 63. The second traction portion 67 is a second hanging ear. The second hanging ear is embedded in the second groove 71. Further, there are two traction steering devices 83. The two traction steering devices 83 are respectively arranged on opposite sides of the energy storage device 81. Therefore, the firmness of the connection between the piston 29 and the striker assembly 32 can be enhanced by the two traction steering devices 83.

[0051] Furthermore, a tension adjusting device is also provided on the piston 29. The tension adjusting device is used to adjust the tension of the traction member 49, and the tension is greater than the maximum thrust generated by the energy storage device 81 when storing energy, so that the length of the traction member 49 is almost unchanged when in motion and when stationary; the traction member 49 is pressed against the traction wheel 47 by the tension, and can drive the traction wheel 47 to rotate, and there is no relative friction movement between the surface of the traction member 49 and the surface of the traction wheel 47. In this way, the motion energy loss can be greatly reduced, the energy stored in the energy storage device 81 can be transferred to the striker assembly 32 to the greatest extent, and the wear and heat can be reduced.

[0052] Specifically, Figure 11 , Figure 12 The tension adjustment device includes a column 73 and an adjusting screw 75. The column 73 is sleeved on the rod 63. A through hole is provided in the column 73. The adjusting screw 75 is inserted into the through hole. The adjusting screw 75 is used to connect the column 73 with the piston 29. Therefore, when the adjusting screw 75 is rotated, the distance between the rod 63 and the piston 29 can be adjusted, thereby adjusting the tension of the traction member 49. Furthermore, the tension adjustment device also includes a tension indicating scale 79 for indicating the adjustment amount of the tension of the traction member 49.
