Description

Technical Field

[0001] This utility model relates to the field of electric nail gun technology, and in particular to an electric nail gun with an adjustable nail gun rod stop position. Background Technology

[0002] In existing electric nail guns, after a period of use, the cylinder pressure decreases, resulting in insufficient power. Some require disassembly, refilling, and reassembly to restore power. Such nail guns demand a high level of operator skill and have very low efficiency. Some nail guns use a delayed shutdown method—such as a long press or two long and two short presses—to delay the nail-shooting rod's movement at the cylinder's outer end. This allows for refilling with a regular air compressor when the cylinder pressure is at its lowest, making it difficult for the operator to determine if the nail-shooting rod is in the desired functional state. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electric nail gun with an adjustable nail gun rod stop position.

[0015] The beneficial effects of this utility model are:

[0016] 1) In this technology, through the coordinated use of components such as the nail gun rod, drive shaft, winch disc, and winch shaft, the nail gun rod can completely compress the pneumatic cylinder assembly. The position of the nail gun rod can be changed when the nail gun is stopped by rotating the adjusting ring. This is significant because when the nail gun needs to be pneumatically refilled, the nail gun rod can be quickly stopped at the outer end of the cylinder, where the internal air pressure is at its lowest. This allows for direct refilling of the nail gun with a standard air compressor without the need to disassemble the tool and place the nail gun rod at the outer end of the cylinder. After the nail gun has been refilled, rotating the adjusting ring returns the nail gun to the position where the nail gun rod can return to the inner end of the cylinder, allowing the nail gun to be used normally. The entire refilling process does not require complete disassembly and reassembly of the nail gun, making it simple and quick. This easily solves the problem of difficult refilling of nail guns.

[0017] 2) In this technology, the length of the movable tube inside the nail tube sleeve is adjusted by adjusting the adjusting rod, thereby controlling the distance between the end of the nail gun rod and the end of the movable tube. The end of the nail gun rod acts on the nail, thus realizing the adjustment of the nail penetration depth.

[0018] 3) In this technology, the adjustment disc serves two purposes: first, it facilitates manual rotation of the adjustment rod, and second, it allows for better contact with the adjustment block, reducing the height of the adjustment block design.

[0019] 4) In this technology, the anti-rotation component and the anti-disengagement snap ring are used together to effectively prevent the adjusting rod from rotating during use. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. 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.

[0030] See Figures 1-8 This utility model provides a technical solution:

[0031] An electric nail gun with an adjustable nail gun rod stop position includes a winch box 1, a nail tube sleeve 2, a nail gun rod 3, a drive shaft 4, a winch disc 5, a winch shaft 6, a depth adjustment assembly, an energy storage power assembly, and a pneumatic cylinder assembly. The winch box 1 is provided with a winch groove 7. One end of the nail tube sleeve 2 is located in the winch groove 7. The depth adjustment assembly is located on the other end of the nail tube sleeve 2. The nail gun rod 3 is located in the nail tube sleeve 2. The other end of the nail gun rod 3 is connected to the pneumatic cylinder assembly, which is connected to the winch box 1. The nail gun rod 3 is provided with at least two push tooth grooves 8, which cooperate with the winch shaft 6. The two ends of the winch shaft 6 are respectively located on two winch discs 5. Both winch discs 5 are located on the drive shaft 4 and are located in the winch grooves 7. The drive shaft 4 is rotatably mounted on the winch box 1 and is connected to the energy storage power assembly. The energy storage power assembly is located on the winch box 1. Both ends of the drive shaft 4 are mounted on the winch box 1 via bearings 50, and a flat washer 51 is provided between the bearing 50 and the winch disc 5. A winch shaft sleeve 52 is provided on the winch shaft 6, and the winch shaft sleeve 52 is located between two winch discs 5. At least three winch shafts 6 are provided between two winch discs 5, and adjacent winch shafts 6 are equally spaced. The electric nail gun also includes an outer connecting housing 55 and a nail gun sleeve 56. The winch box 1, nail tube sleeve 2, nail gun rod 3, drive shaft 4, winch disc 5, winch shaft 6, depth adjustment assembly, energy storage power assembly, and pneumatic cylinder assembly are all fixed inside the outer connecting housing 55. The nail gun sleeve 56 is used to carry the nails. One end of the nail gun sleeve 56 is located on the depth adjustment assembly, and the other end of the nail gun sleeve 56 is located on the outer connecting housing 55. One end of the winch box 1 is threaded and threadedly connected to the pneumatic cylinder assembly. The other end of the winch box 1 has a through winch groove 7, which is used to install the nail tube sleeve 2, the nail rod 3, the drive shaft 4, the winch disc 5, and the winch shaft 6. One side of the winch box 1 is used to install the energy storage power assembly. The depth adjustment assembly is used to adjust the length of the end of the nail rod 3 within the depth adjustment assembly. The energy storage power assembly drives the drive shaft 4 to rotate, the drive shaft 4 drives the winch disc 5 to rotate, and the winch disc 5 drives the winch shaft 6 to rotate. The winch shaft 6 engages with the push tooth groove 8 on the nail rod 3, thereby compressing the pneumatic cylinder assembly through the nail rod 3. When the air in the pneumatic cylinder assembly is compressed and released, it pushes the nail rod 3 to move. The end of the nail rod 3 pushes the nail and shoots it into the building.Eight winch shafts 6 are evenly arranged between the two winch discs 5. The eight winch shafts 6 are arranged on the same circle, which is coaxial with the drive shaft 4. In order to allow the nail gun rod 3 to be pushed out smoothly, two adjacent winch shafts 6 that would block the movement of the nail gun rod 3 are removed. At the same time, the nail gun rod 3 is provided with six push tooth grooves 8 that correspond one-to-one with the winch shafts 6. In order to prevent the winch shafts 6 from falling out, both winch discs 5 are provided with winch blind holes that cooperate with the winch shafts 6. The six winch shafts 6 are all arranged parallel to each other with the drive shaft 4. In order to prevent the winch shafts 6 from being severely worn during use, each winch shaft 6 is fitted with a winch shaft sleeve 52. The winch shaft sleeve 52 directly cooperates with the push tooth groove 8. The cross section of the winch shaft sleeve 52 that cooperates with the push tooth groove 8 on the push end side of the nail gun rod 3 is a regular polygon with no less than five sides. The other winch shaft sleeves 52 are all circular. To prevent wear on the drive shaft 4 during rotation, it is connected to the winch box 1 via two bearings 50. Two winch discs 5 are positioned between the bearings 50. To prevent friction between the bearings 50 and the winch discs 5, flat washers 51 separate them. An anti-rotation plane is provided on the drive shaft 4, ensuring synchronous rotation between the winch discs 5 and the drive shaft 4 under the action of this anti-rotation plane.

[0032] In some embodiments, the depth adjustment assembly includes a movable tube 9, an adjusting rod 10, an adjusting slider 11, an ejector spring 12, a guide plate 13, and a stabilizing plate 14. The movable tube 9 is slidably disposed within the nail tube sleeve 2, and the nail gun 3 is slidably disposed within the movable tube 9. An adjusting block 15 is provided on the movable tube 9 to cooperate with one end of the adjusting rod 10. A guide groove 16 is provided on the nail tube sleeve 2 to cooperate with the adjusting block 15. The other end of the adjusting rod 10 is threadedly engaged with the adjusting slider 11. The adjusting slider 11 is slidably disposed on the nail tube sleeve 2 and is located between the guide plate 13 and the stabilizing plate 14. Both the guide plate 13 and the stabilizing plate 14 are fixedly disposed on the nail tube sleeve 2. The two ends of the ejector spring 12 abut against the adjusting slider 11 and the winch box 1, respectively. A guide hole 17 is provided on the guide plate 13 to cooperate with the adjusting rod 10, and a spring hole 18 is provided on the stabilizing plate 14 to cooperate with the ejector spring 12. The movable tube 9 is movable within the nail tube sleeve 2. The nail tube sleeve 2 has an installation groove into which the end of the nail gun sleeve 56 can be inserted. A limiting groove, which is an elongated groove, is provided on the movable tube 9. A protrusion on the end of the nail gun sleeve 56 mates with the limiting groove. Therefore, when the nail gun sleeve 56 is inserted into the installation groove, the movable tube 9 can move. When the nail gun sleeve 56 is removed, the movable tube 9 can also be removed from the nail tube sleeve 2. Because the adjusting block 15 engages with the guide groove 16, the movable tube 9 cannot rotate within the nail tube sleeve 2. The movable tube 9 is used to hold the nail gun rod 3, which pushes the nail in the movable tube 9 out to achieve fixation between the two objects. The adjusting slider 11 can slide between the guide plate 13 and the stabilizing plate 14. The adjusting slider 11 can rest against the stabilizing plate 14. One end of the adjusting rod 10 rests against the adjusting block 15 on the movable tube 9, and the other end of the adjusting rod 10 is threadedly engaged with the adjusting slider 11, thereby adjusting the relative position between the nail tube sleeve 2 and the movable tube 9. The nail gun 3 is set inside the pneumatic cylinder assembly, which is fixedly connected to the stabilizing plate 14 through the winch box 1 and the nail tube sleeve 2. Therefore, the extension length of the nail gun 3 is constant within the movable tube 9, and the nail penetration depth is achieved by adjusting the movable tube 9. The movable tube 9 and the adjusting block 15 are integrally formed. The guide plate 13 guides the movement of the adjusting rod 10. The nail tube sleeve 2, the movable tube 9, the adjusting rod 10, and the nail gun 3 are arranged parallel to each other. The guide plate 13 and the stabilizing plate 14 are integrally formed with the nail tube sleeve 2. The ejector spring 12 is used to push the adjusting slider 11. When using the electric nail gun, the entire nail gun is pressed down manually, and the movable tube 9 on the nail gun comes into contact with the object. The movable tube 9 moves the adjusting slider 11 by pressing it down through the adjusting rod 10. When the movable tube 9 stops moving, the nail gun can be controlled to fire nails. After firing the nail, the ejector spring 12 causes the movable tube 9 to extend forward and return to its initial position. An adjusting disc that cooperates with the adjusting block is coaxially fixed on the end of the adjusting rod 10. The adjusting disc has two functions: first, it makes it easier for the operator to rotate the adjusting rod 10 by hand; second, it allows for better contact with the adjusting block 15, reducing the design height of the adjusting block 15.

[0033] In some embodiments, a detection rod 19 is fixedly mounted on the adjusting slider 11, and a first detection block 20 is fixedly mounted on the detection rod 19. A first detection sensor 21 that cooperates with the first detection block 20 is fixedly mounted on the winch box 1. The detection rod 19 has a mounting hole, and the first detection block 20 is a magnet (as in the prior art) mounted within the mounting hole. A rubber sleeve 53 is fitted onto the detection rod 19, fixing the first detection block 20 to the detection rod 19. The first detection sensor 21 is a Hall effect switch (as in the prior art). When the first detection sensor 21 detects the first detection block 20, it indicates that the movable tube 9 is in contact with an object and has been compressed, preventing further movement. At this time, the first detection block 20 transmits a signal to the control board (as in the prior art) inside the electric nail gun. The control board controls the indicator light to illuminate, and the electric nail gun is then manually controlled to fire the nail. The first detection block 20 is fixedly mounted within the locking member 34, facilitating its installation and fixation. The locking member 34 is fixed to the winch box 1 with screws.

[0034] In some embodiments, a limiting groove 22 is provided on the threaded end of the adjusting rod 10, and a limiting spring 23 that cooperates with the limiting groove 22 is provided in the limiting groove 22. The adjusting slider 11 is disposed between the limiting spring 23 and the guide plate 13. The guide plate 13 is provided with a through anti-rotation hole 24, and an anti-rotation component 25 that cooperates with the anti-rotation hole 24 is provided in the anti-rotation hole 24. A plurality of anti-rotation grooves 26 that cooperate with the anti-rotation component 25 are provided on the side wall of the adjusting rod 10. The anti-rotation grooves 26 are arranged parallel to the adjusting rod 10. The guide plate 13 is provided with an anti-disengagement groove 27 that cooperates with the anti-rotation hole 24, and an anti-disengagement spring 28 that prevents the anti-rotation component 25 from falling out of the anti-rotation hole 24 is provided in the anti-disengagement groove 27. The limiting groove 22 is provided to install the limiting spring 23, and the limiting spring 23 limits the adjusting slider 11 to prevent the adjusting slider 11 from separating from the adjusting rod 10. The side wall of the adjusting rod 10 is evenly provided with two, three, four, or five anti-rotation grooves 26, and one side of the anti-rotation component 25 is disposed in the anti-rotation groove 26, while the other side of the anti-rotation component 25 is provided with an anti-rotation hole 24, thus preventing the adjusting rod 10 from rotating during use. Since the anti-rotation component 25 is a steel ball as in the prior art, an anti-disengagement spring 28 is provided to prevent the steel ball from detaching from the anti-rotation hole 24. After the anti-disengagement spring 28 is engaged, one side of the steel ball contacts the anti-disengagement spring 28, and the other side contacts the anti-rotation groove 26. To prevent the anti-disengagement spring 28 from moving, an anti-disengagement groove 27 is provided on the guide plate, and the anti-disengagement groove 27 cooperates with the anti-disengagement spring 28.

[0035] In some embodiments, a detection disc 29 is fixedly mounted on the winch 5, and a second detection block 30 is mounted on the detection disc 29. An adjusting ring 31 is mounted on the winch box 1, and a second detection sensor 32 that cooperates with the second detection block 30 is mounted on the adjusting ring 31. The adjusting ring 31 is coaxially mounted with the drive shaft 4, and a rotating groove 57 that cooperates with one end of a positioning spring 33 is provided on the outer wall of the adjusting ring 31. The other end of the positioning spring 33 is fixed to the winch box 1 by a locking member 34. The detection disc 29 is provided with a mounting groove, and the second detection block 30 is fixed in the mounting groove. The second detection block 30 is a magnet in the prior art, and the second detection sensor 32 is a Hall switch in the prior art. Directly setting the mounting groove on the winch 5 would reduce the strength of the winch 5. Therefore, the detection disc 29 is provided to mount the second detection block 30. The detection disc 29 is fixedly connected to the winch 5 and rotates synchronously with the winch 5. A flat washer 51 separates the bearing 50 from the detection disc 29 to prevent the detection disc 29 from being damaged by friction. The adjusting ring 31 is equipped with a lever 54, which has a mounting slot for installing the second detection sensor 32. The lever 54 drives the adjusting ring 31 to rotate on the winch box 1. When the second detection block 30 is detected by the second detection sensor 32, it indicates that the winch 5 has moved the nail gun rod 3 to the preset position, and it also indicates that the air pressure in the pneumatic cylinder assembly has been compressed to the preset value. At this time, the second detection sensor 32 transmits a signal to the control board inside the electric nail gun, and the corresponding control signal light on the control board lights up. At this time, the electric nail gun can be manually aimed at the position of the object to be fixed, and the nail can be fired after the movable tube 9 is compressed. The outer wall of the adjusting ring 31 is equipped with multiple rotating slots 57. After the end of the positioning leaf spring 33 is inserted into the rotating slot 57, it can effectively prevent the adjusting ring 31 from rotating without external force. The adjusting ring 31 can only be rotated manually. The locking member 34 is used to fix the positioning leaf spring 33 and the first detection sensor 21 on the winch box 1. The position of the nail gun rod 3 can be changed when the nail gun is stopped by rotating the adjusting ring 31. This is significant because when the nail gun needs to be pneumatically added, the nail gun rod 3 can be quickly stopped at the outer end of the cylinder, where the internal air pressure is at its lowest. This allows for direct pneumatic addition of the nail gun using a regular air compressor, eliminating the need to disassemble the nail gun and place the nail gun rod 3 at the outer end of the cylinder before adding air. After the nail gun has been pneumatically added, rotating the adjusting ring 31 again allows the nail gun to return the nail gun rod 3 to the inner end of the cylinder, at which point the nail gun can be used normally. The entire pneumatic process does not require complete disassembly and reassembly of the nail gun, making it simple, quick, and easily solving the problem of difficult pneumatic addition for nail guns.

[0036] In some embodiments, a locking tooth shaft 35 is provided on the middle part of the nail tube sleeve 2, and a locking tooth 36 is rotatably provided on the locking tooth shaft 35. The locking tooth 36 engages with the locking tooth groove 37 on the nail rod 3. A spring ear 38 is provided on the locking tooth 36, and one end of the spring ear 38 is connected to a tension spring 39. The other end of the tension spring 39 is connected to a spring shaft 40 on the end of the nail tube sleeve 2. An unlocking block 41 is fixedly provided on the locking tooth 36, and the unlocking block 41 engages with the unlocking protrusion 42 on the winch 5. The locking tooth shaft 35 is used to install the locking tooth 36. The locking tooth 36 rotates around the locking tooth shaft 35. When the nail rod 3 moves to a certain position, the locking tooth 36 is inserted into the locking tooth groove 37 under the action of the tension spring 39, thus preventing the nail rod 3 from popping out under the action of the pneumatic cylinder assembly. An unlocking protrusion 42 is fixedly provided on the outer wall of the winch 5. After the unlocking protrusion 42 is pressed against the unlocking block 41, the locking tooth 36 is disengaged from the locking tooth groove 37. At this time, the nail gun rod 3 is ejected under the action of the pneumatic cylinder assembly, realizing the nail firing.

[0037] In some embodiments, the energy storage power assembly includes a drive motor 43, a reducer 44, and an anti-rotation protrusion 45. The drive motor 43 is fixed to the reducer 44 by a pin 46, and the reducer 44 is mounted on the winch box 1 by the anti-rotation protrusion 45. The output of the drive motor 43 is connected to the input of the reducer 44, and the output of the reducer 44 is connected to the drive shaft 4. Both the drive motor 43 and the reducer 44 are existing technologies. The drive motor 43 drives the drive shaft 4 to rotate via the reducer 44. The pin 46 securely connects the housing of the drive motor 43 to the housing of the reducer 44, and the anti-rotation protrusion 45 restricts the rotation of the housing of the reducer 44 relative to the winch box 1.

[0038] In some embodiments, the pneumatic cylinder assembly includes a cylinder body 47, a piston 48, and a brake ring 49. The cylinder body 47 is sealed and mounted on the winch box 1. The piston 48 is sealed and slidably mounted within the cylinder body 47 and fixedly connected to the nail gun rod 3. The brake ring 49 is fixedly mounted on the winch box 1 and cooperates with the piston 48. The cylinder body 47 and the winch box 1 are connected by a threaded seal. The piston 48 is sealed and slidably mounted within the cylinder body 47. The nail gun rod 3 is fixedly connected to the piston 48 and coaxially arranged. The brake ring 49 is fixedly mounted on the winch box 1 to buffer the impact force on the piston 48, preventing direct interaction between the winch box 1 and the piston 48 from damaging the entire nail gun.
