Description

Technical Field

[0001] This utility model relates to the technical field of nail feeding devices for electric nail guns, and in particular to a nail feeding device for an electric nail gun. Background Technology

[0002] An electric nail gun is a product composed of a gun body assembly and a magazine assembly. The magazine assembly consists of accessories such as a gun head, a gun cover, a fixed magazine, and a movable magazine. The nail is fed into the slot in the gun cover by a compression spring or a tension spring. When the firing pin comes out of the nozzle, the nail is ejected. The nail pusher of the existing nail feeding device may have a problem with poor balance in the process of pushing the nail towards the nozzle.

[0003] For example, Chinese utility model patent CN204868765U discloses a nail feeding device for an electric nail gun. An inner nail slot is inserted into the housing, and a sliding rod is located within the inner nail slot. The sliding rod passes through the inner nail slot, and a compression spring is fitted onto the sliding rod. A nail pusher is mounted on the inner nail slot and slidably connected to the sliding rod. The nail pusher is pushed towards the nozzle end under the action of the compression spring. In this design, the nail pusher is U-shaped and is pushed solely by a spring on the outside of the sliding rod. If the nail needle length of the electric nail gun is small, there is no problem. However, if the nail needle length is large, after prolonged use, the electric nail gun may experience increased gaps due to friction between the nail pusher and the sliding rod or the inner nail. Longer nail needles may exhibit slight tilting, which could cause jamming when fed to the nozzle. Based on this, a nail feeding device for an electric nail gun is proposed. Utility Model Content

[0004] To address the technical problem of balance in the nail feeding device of an electric nail gun, this utility model provides a nail feeding device for an electric nail gun.

[0005] This utility model is achieved using the following technical solution: a nail feeding device for an electric nail gun, comprising a mounting plate, two limiting plates fixedly connected to one side of the mounting plate, toothed plates fixedly connected to one side of each of the two limiting plates, gears meshing between the two toothed plates, a nail pusher connected to one side of each of the two gears in a common rotation, a spring pushing mechanism provided on the side of the mounting plate near the nail pusher, a nail mounting mechanism provided on the side of the nail pusher near the mounting plate, and a push-pull cover plate mechanism provided on one side of the mounting plate.

[0006] As a further improvement to the above solution, the spring pushing mechanism includes a slide rod fixedly connected to one side of the mounting plate, a spring sleeved on the slide rod, a sliding sleeve slidably connected to the outside of the slide rod, the lower side of the sliding sleeve fixedly connected to the upper end of the spring, the lower end of the spring fixedly connected to the mounting plate, and one side of the sliding sleeve fixedly connected to one side of the push pin table.

[0007] As a further improvement to the above solution, the nail mounting mechanism includes a placement plate fixedly connected to the mounting plate on the side near the nail pusher, and the space formed by the nail pusher, the placement plate and the two limiting plates is used to place nails for an electric nail gun.

[0008] As a further improvement to the above solution, the push-pull cover mechanism includes slots opened on both sides of the mounting plate, with a card plate slidably connected in each of the two slots, and a cover plate fixedly connected to the side of the two card plates away from the mounting plate. One of the card plates has a running groove, a positioning bolt mechanism is provided on one side of the card plate, and a card plate driving mechanism is provided on the side of the cover plate close to the mounting plate.

[0009] As a further improvement to the above solution, the positioning bolt mechanism includes a screw rod fixedly connected to the side of the walkway near the limiting plate, the screw rod passing outward through the walkway, and a positioning nut threaded onto the side of the screw rod away from the limiting plate.

[0010] As a further improvement to the above solution, the card plate driving mechanism includes a pull plate fixedly connected to the side of the cover plate near the mounting plate, and a stop block fixedly connected to the side of the push nail stage near the cover plate, the stop block being configured to cooperate with the pull plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses two toothed plates, gears, slide rods and springs to work together. When the nail pusher pushes the nail needle upwards and moves it closer to the nozzle, the gears on both sides mesh with the toothed plates and roll, reducing the friction between the slide sleeve and the slide rod. In the long term of use, this helps to improve the accuracy of the nail pusher's up and down movement and avoids deviation. This improves the balance of the nail feeding device when the nail needle enters the nozzle and reduces the probability of nail jamming.

[0013] 2. This utility model uses a combination of a card plate drive mechanism and a positioning bolt mechanism. When nailing is required, the cover plate is first manually pulled down. At this time, the pull plate is blocked by the stop block, causing the nail pusher to move downward. The spring is compressed and deformed. Then, by tightening the positioning nut, the cover plate is positioned relative to the limiting plate and nails can be inserted. The operator does not need to use one hand to compress the spring to prevent it from rebounding, which makes it easier for the operator to insert nails. Attached Figure Description

[0021] Example:

[0022] Please combine Figures 1-4 This embodiment of an electric nail gun feeding device includes a mounting plate 1. The upper side of the mounting plate 1 is mounted on the lower side of the electric nail gun. Two limiting plates 3 are fixedly connected to one side of the mounting plate 1. The distance between the two limiting plates 3 is adapted to the length of the nail. A toothed plate 14 is fixedly connected to one side of each of the two limiting plates 3. The two toothed plates 14 are respectively meshed with gears 17. A nail pusher 5 is rotatably connected to one side of each of the two gears 17. A spring pushing mechanism is provided on the side of the mounting plate 1 near the nail pusher 5. A nail mounting mechanism is provided on the side of the nail pusher 5 near the mounting plate 1. A push-pull cover plate mechanism is provided on one side of the mounting plate 1.

[0023] Please combine Figure 3 As shown, the spring pushing mechanism includes a slide rod 13 fixedly connected to one side of the mounting plate 1, a spring 15 sleeved on the slide rod 13, a sliding sleeve 16 slidably connected to the outside of the slide rod 13, the lower side of the sliding sleeve 16 fixedly connected to the upper end of the spring 15, the lower end of the spring 15 fixedly connected to the mounting plate 1, and one side of the sliding sleeve 16 fixedly connected to one side of the push pin table 5.

[0024] Please combine Figure 3 As shown, the nail mounting mechanism includes a placement plate 4 fixedly connected to the mounting plate 1 on the side near the pusher plate 5. The placement plate 4 has a vertical movement channel and serves as a support. The space enclosed between the pusher plate 5, the placement plate 4, and the two limiting plates 3 is used to place the nails for the electric nail gun.

[0025] Please combine Figure 1 As shown, the push-pull cover mechanism includes slots 2 on both sides of the mounting plate 1. The slots 2 are T-shaped slots. Each slot 2 has a slidably connected plate 6. The lower end of the plate 6 is a T-shaped block. The two plates 6 are fixedly connected to a cover plate 10 on the side away from the mounting plate 1. The distance between the cover plate 10 and the placement plate 4 is adapted to the thickness of the nail. One of the plates 6 has a groove 7. The groove 7 provides space for the screw 8 to move when the cover plate 10 moves up and down, and also has a certain limiting function. A positioning bolt mechanism is provided on one side of the plate 6, and a plate drive mechanism is provided on the side of the cover plate 10 near the mounting plate 1.

[0026] Please combine Figure 1 As shown, the positioning bolt mechanism includes a screw 8 fixedly connected to the side of the walkway 7 near the limiting plate 3. The screw 8 passes outward through the walkway 7, and a positioning nut 9 is threaded onto the side of the screw 8 away from the limiting plate 3.

[0027] Please combine Figure 1 As shown, the card plate driving mechanism includes a pull plate 11 fixedly connected to the side of the cover plate 10 near the mounting plate 1, and a stop block 12 fixedly connected to the side of the pusher table 5 near the cover plate 10.

When the cover plate 10 is pulled down, the pusher table 5 can be driven to descend through the stop block 12.

[0028] The implementation principle of the nail feeding device of an electric nail gun in this embodiment is as follows: When nailing is required, the user first loosens the positioning nut 9 and pulls the cover plate 10 down to a certain position. The clamping plate 6 moves down along the clamping groove 2. At this time, the pull plate 11 on one side of the cover plate 10 and the stop block 12 block it, indirectly driving the nail pusher 5 to move down. At this time, the gear 17 meshes with the toothed plate 14 and rotates and moves down. The sliding sleeve 16 moves down along the sliding rod 13, and the spring 15 is compressed and deformed. Then, the positioning nut 9 is tightened again to keep the cover plate 10 in the same position. Then, the prepared nail is placed on the nail pusher 5, and the two ends of the nail just abut against the limiting plates 3 on both sides, and the other side abuts against the placement plate 4. Then, the positioning nut 9 is loosened, and the cover plate 10 is pushed up to connect with the electric gun. At this time, the pull plate 11 moves up and disengages from the stop block 12. The spring 15 rebounds and pushes the nail into the nozzle.
