[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of an adjustable nailing depth structure for a manual nailing machine, comprising a housing 1, a movable box 11 slidably connected between the top and bottom of the inner wall of the housing 1, a first spring 9 fixedly connected to the front side of the inner wall of the movable box 11, a rotating rod 12 rotatably connected between the top and bottom of the inner wall of the housing 1, a trigger 13 rotatably connected to the right side of the rotating rod 12, the trigger 13 being tightly fitted with the movable box 11, a connecting box 17 fixedly connected to the right side of the housing 1, a dust collection box 4 fixedly connected to the right side of the housing 1, a filter plate 15 fixedly connected between the front and rear sides of the inner wall of the dust collection box 4, an air pump 6 fixedly connected to the front side of the housing 1, an air outlet hopper 7 fixedly connected to the output end of the air pump 6, a connecting pipe 5 fixedly connected to the input end of the air pump 6, the bottom end of the connecting pipe 5 being fixedly connected to the dust collection box 4, a dust suction hopper 16 fixedly connected to the bottom of the dust collection box 4, and an adjustment component provided inside the connecting box 17 for adjusting the nail outlet height.
[0024] Specifically, firstly, air is drawn into the dust collection box 4 through the connecting pipe 5 connected to the air pump 6, creating a negative pressure state inside the dust collection box 4. At this time, the dust suction hopper 16 draws in air, sucking the debris into the dust collection box 4 through the gap between the extension block 8 and the outer shell 1. The debris is blocked by the internal filter plate 15. The air pump 6 blows the gas towards the air outlet hopper 7, thereby continuously blowing air onto the nail outlet to remove debris from the contact surface and prevent it from affecting the nailing accuracy.
[0025] Reference Figure 3 and Figure 4 The adjustment assembly includes a gear 21, which is rotatably connected to the inner wall of the connecting box 17. A rack 24 is meshed with the top of the gear 21. An extension block 8 is fixedly connected to the front side of the rack 24. A ratchet 20 is fixedly connected to the right end of the gear 21. A limiting member 22 is rotatably connected between the left and right sides of the inner wall of the connecting box 17. A second spring 23 is fixedly connected between the limiting member 22 and the inner wall of the connecting box 17. A first knob 19 is fixedly connected to the right end of the ratchet 20.
[0026] Specifically, during operation, the user rotates the first knob 19 to drive the ratchet 20 to rotate, thereby rotating the gear 21. The gear 21 drives the meshing rack 24 to move, and the rack 24 pushes the extension block 8 to move, adjusting the distance between the nail outlet and the board. This allows the user to easily observe the position of the nail outlet. The extension block 8 can be removed and replaced to adapt to different work requirements. Replacing with a longer extension block 8 increases the distance between the nail outlet and the board, thereby adjusting the nailing depth. During this process, the second spring 23 presses against the limiting member 22, making it fit against the ratchet 20 to prevent the ratchet 20 from rotating back, thus fixing the position of the extension block 8. Moving the limiting member 22 disengages it from the ratchet 20, allowing the gear 21 to rotate normally. This allows the extension block 8 to be retracted, making it fit tightly against the nail outlet.
[0027] Reference Figure 2 The first spring 9 has a pressing component 10 at its rear end. A threaded rod 3 is fixedly connected to the rear side of the pressing component 10. The threaded rod 3 is threadedly connected to the outer shell 1. A second knob 25 is fixedly connected to the rear end of the threaded rod 3.
[0028] Specifically, by turning the second knob 25, the user can drive the threaded rod 3 to rotate, thereby pushing the extrusion piece 10 to move, adjusting the compression degree of the first spring 9, and thus changing the force and effect of nailing to adapt to different nailing conditions and needs.
[0029] Reference Figure 2 A pressing rod 2 is rotatably connected between the top and bottom of the inner wall of the outer casing 1, and the pressing rod 2 is tightly fitted with the left end of the rotating rod 12.
[0030] Specifically, the pressing rod 2, which is rotatably connected between the top and bottom of the inner wall of the outer casing 1, is tightly fitted to the left end of the rotating rod 12. Its significance is that when the pressing rod 2 is pressed, it can push the rotating rod 12 to rotate, thereby driving the trigger 13 to move. When the trigger 13 moves, it drives the moving box 11 to move upward and squeeze the first spring 9. When it moves to a certain distance, the trigger 13 disengages from the moving box 11. At this time, the first spring 9 rebounds, and the moving box 11 moves forward to touch the buffer block 14. The buffer block 14 hits the nail, thereby realizing the nail-driving trigger operation.
[0031] Reference Figure 2 A torsion spring 26 is provided between the rotating rod 12 and the inner wall of the outer casing 1. One end of the torsion spring 26 is fixedly connected to the outer casing 1, and the other end of the torsion spring 26 is fixedly connected to the rotating rod 12.
[0032] Specifically, the torsion spring 26 is used to automatically reset the rotating rod 12, thereby enabling the next nailing operation and ensuring the continuity of nailing.
[0033] Reference Figure 2 Two buffer blocks 14 are provided on the front side of the movable box 11. The two buffer blocks 14 are tightly fitted together, and both buffer blocks 14 are slidably connected to the inner wall of the outer shell 1.
[0034] Specifically, the buffer block 14 is used to help disperse and reduce the impact force generated when the spring is compressed, reduce the impact of vibration on other parts of the nail gun, and increase the stability and service life of the nail gun.
[0035] Reference Figure 3 and Figure 4 A slide rod 18 is fixedly connected to the right side of the extension block 8. The slide rod 18 passes through and extends into the inside of the connecting box 17 on the right side, and the slide rod 18 is slidably connected to the connecting box 17.
[0036] Specifically, the slide bar 18 provides guidance and stable support for the movement of the extension block 8, ensuring the straightness and smoothness of the movement of the extension block 8, preventing the extension block 8 from deviating or getting stuck during the movement, thereby accurately adjusting the height of the nail outlet, improving nailing accuracy and ease of operation.
[0037] Reference Figure 3 The bottom front side of the air vent 7 is fixedly connected to the outer shell 1, and the top front side of the dust hopper 16 is fixedly connected to the outer shell 1.
[0038] Specifically, the connection between the air outlet 7 and the dust collection 1 ensures that the air outlet 7 and the dust collection 16 are firmly positioned and will not shake or shift during operation. This guarantees stable and reliable air outlet and dust collection effects, helps maintain the normal operation and good performance of the nailing machine, and improves the efficiency and quality of nailing work.
[0039] Working principle: When the user uses it, first start the air pump 6, and draw air into the dust collection box 4 through the connecting pipe 5, so that the dust collection bucket 16 draws in air and sucks in the debris from the gap between the extension block 8 and the outer shell 1. The debris is blocked by the filter plate 15, and the air pump 6 blows the air out of the air outlet 7 to blow air into the nail outlet to remove the debris.
[0040] Then, turn the first knob 19 to drive the ratchet 20 to rotate, so that the gear 21 rotates and drives the rack 24 to move, pushing the extension block 8 to move and adjust the distance between the nail outlet and the plate. The extension block 8 can also be replaced to adapt to different needs. Turn the second knob 25 to drive the threaded rod 3 to push the extrusion piece 10 to adjust the compression degree of the first spring 9.
[0041] Pressing the pressing lever 2 pushes the rotating lever 12, which in turn drives the trigger 13. The moving trigger 13 causes the moving box 11 to move upward and compress the first spring 9. After moving to a certain distance, the trigger 13 disengages from the moving box 11, and the first spring 9 rebounds. The buffer block 14 in front of the moving box 11 strikes the nail to drive it into place. The torsion spring 26 causes the rotating lever 12 to automatically reset for the next nailing operation.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
