[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0024] See also Figure 1-6 The utility model discloses a nailing device for driving C-shaped nails, including a gun body, a gas exchange mechanism 2 and a foot switch (not shown in the figure), wherein the gun body includes an air control seat 1 and a nailing mechanism, wherein the air control seat 1 is provided with a nail pushing cavity, and the nailing mechanism includes a nail pushing assembly movably connected to the air control seat 1, wherein the nail pushing assembly divides the nail pushing cavity into an entry cavity 13 and a retreat cavity 16.

[0025] The ventilation mechanism 2 is installed on the air control seat, and is provided with an air inlet 21 and an air outlet; the ventilation mechanism 2 is electrically connected to the foot switch, and the ventilation mechanism 2 connects the air inlet 21 and the air outlet with the inlet cavity 13 and the retreat cavity 16 respectively through the foot switch, or connects the air outlet and the air inlet 21 with the inlet cavity 13 and the retreat cavity 16 respectively, so as to drive the pin push assembly to move back and forth.

[0026] The nailing device of the utility model is provided with a ventilation mechanism and a foot switch. The foot switch can be used to control the ventilation mechanism to turn on and off, so that the ventilation mechanism changes its internal air path structure, so that the air inlet and the air outlet can be alternately connected with the inlet cavity and the outlet cavity in the air control seat, so that the air inlet channel and the air outlet channel in the air control seat are alternately changed, and the nail pushing component is driven to move back and forth, so as to realize the two operations of pushing and clamping nails of the nailing device. In this process, the operator only needs to step on the foot switch to control the ventilation mechanism, realize the change of the air path, and thus drive the nail pushing component to realize nailing. It not only frees the hands of the operator and reduces the labor intensity, but also facilitates the nailing at the nailing position of the object, thereby ensuring the nailing quality.

[0027] Preferably, the ventilation mechanism 2 is a solenoid valve. More preferably, the solenoid valve is an AirTac solenoid valve 4V210-08 AC220V, but not limited thereto.

[0028] It should be noted that the air source is connected to the air inlet 21 to supply air to the air control seat 1. Therefore, a joint 211 is provided on the air inlet 21 to facilitate connection with the air source.

[0029] Among them, Figure 1-5As shown, the utility model further includes a base 10, the air control seat 1 is fixedly mounted on the base 10, and the nailing mechanism is mounted on the base 10 through a cushion block 8. The setting of the base makes the gun body more stable during nailing, so that the nailing effect is better and it is also convenient for transportation. The cushion block plays a role in supporting and stabilizing the nailing mechanism. Preferably, the air control seat is fixedly connected to the base through a connecting plate 17.

[0030] Preferably, if Figure 2-5 As shown, a sealing gasket 9 is provided between the gas control seat 1 and the ventilation mechanism 2. The sealing gasket is provided to prevent gas from leaking from the gap between the gas control seat and the ventilation mechanism, that is, to play a sealing role. The sealing gasket is a sealing rubber gasket.

[0031] Specifically, the air control seat 1 is provided with a first air port 11, a first air channel 12, a second air port 14 and a second air channel 15. The first air port 11, the first air channel 12 and the inlet cavity 13 are connected in sequence, and the second air port 14, the second air channel 15 and the retreat cavity 16 are connected in sequence. That is, the first air port 11, the first air channel 12 and the inlet cavity 13 constitute the first air channel, and the second air port 14, the second air channel 15 and the retreat cavity 16 constitute the second air channel. When the gas flows into the first air channel, the nail pushing assembly will be pushed toward the retreat cavity, so that the gas in the second air channel flows out, and the nail is pushed. At this time, the first air channel is the inlet channel, and the second air channel is the outlet channel. When the gas flows into the second air channel, the nail pushing assembly will be pushed toward the inlet cavity, so that the gas in the first air channel flows out, and the nail is clamped. At this time, the first air channel is the outlet channel, and the second air channel is the inlet channel.

[0032] Preferably, if Figure 2-5 As shown, the air outlet includes a first air outlet 221 and a second air outlet 222, and the ventilation mechanism 2 makes the air inlet 21 and the first air outlet 221 communicate with the first air outlet 11 and the second air outlet 14 respectively, or makes the air inlet 21 and the second air outlet 222 communicate with the second air outlet 14 and the first air outlet 11 respectively through the foot switch. That is to say, when the foot switch is released, the ventilation mechanism 2 makes the air inlet 21 communicate with the first air outlet 11 and the first air outlet 221 communicate with the second air outlet 14; when the foot switch is stepped on, i.e., the foot switch is closed, the ventilation mechanism 2 makes the air inlet 21 communicate with the second air outlet 14 and the second air outlet 222 communicate with the first air outlet 11. The air path structure inside the ventilation mechanism is changed according to the release or closing state of the foot switch, and the air outlet channel is also changed to communicate with different air outlets to adapt to the change of its structure.

[0033] Preferably, if Figure 2-5 As shown, the air outlet is provided with a muffler 223. More preferably, both the first air outlet 221 and the second air outlet 222 are provided with a muffler 223. The setting of the muffler plays a role in reducing noise.

[0034] Specifically, Figure 2-5 As shown, the nail pushing assembly includes a piston 3, a piston rod 4 and a nail pushing piece 5. The piston 3 is arranged in the nail pushing chamber and is movably connected to the air control seat 1. The piston 3 divides the nail pushing chamber into an entry chamber 13 and a retreat chamber 16; one end of the piston rod 4 is connected to the piston 3, and the other end extends out of the air control seat 1 and is connected to the nail pushing piece 5.

[0035] When the gas flows into the first gas channel, the piston 3 is pushed toward the retreat chamber 16, causing the gas in the second gas channel to flow out, and at the same time, the pin pusher 5 is pushed away from the gas control seat 1 through the piston rod 4. When the gas flows into the second gas channel, the piston 3 is pushed toward the inlet chamber 13, causing the gas in the first gas channel to flow out, and at the same time, the pin pusher 5 is pulled toward the gas control seat 1 through the piston rod 4.

[0036] More specifically, Figure 1-5 As shown, the nail driving mechanism also includes a nail clamping assembly, which includes a mounting plate 6 fixedly connected to the air control seat 1 and a clamp 7 movably connected to the mounting plate 6, and the nail pushing member 5 can contact with the clamp 7 to drive the clamp 7. The provision of the mounting plate makes the movement of the clamp more stable and reliable. The nail pushing member moves driven by the piston and the piston rod, and can contact with the clamp. When the nail pushing member is pushed away from the air control seat, the nail pushing member pushes the nail that falls into the clamp toward the front end of the clamp to prepare for clamping the nail. When the nail pushing member is pulled close to the air control seat, the nail pushing member contacts with the rear end of the clamp, and the lever principle is used to make the front end of the clamp clamp the nail into shape, and the material is rolled tightly and firmly to achieve nailing.

[0037] Further, if Figure 1 As shown, the utility model further comprises a nail guide mechanism 20 connected to the nail clamp assembly, and the nail guide mechanism 20 is used to guide the nails. The nail guide mechanism can adopt the existing technical structure, which will not be described in detail here.

[0038] The working principle of the nailing device of the utility model is as follows:

[0039] like Figure 2-3 As shown, when the operator does not step on the foot switch, that is, the foot switch is in the released state, the air inlet 21 is connected to the first air port 11 through the air exchange mechanism 2, and the first air outlet 221 is connected to the second air port 14 through the air exchange mechanism 2. Figure 2 As indicated by the arrow, the gas flows into the first gas port 11, the first gas channel 12 and the inlet chamber 13 in sequence through the gas inlet 21, pushing the piston 3 toward the retreat chamber 16, so that the gas in the retreat chamber 16 flows through the second gas channel 15 and the second gas port 14 in sequence, and then flows out from the first gas outlet 221. Figure 3 Push the pin in the direction of the arrow.

[0040] like Figure 4-5As shown, when the operator steps on the foot switch, that is, the foot switch is in the closed state, the air inlet 21 is connected to the second air port 14 through the air exchange mechanism 2, and the second air outlet 222 is connected to the first air port 11 through the air exchange mechanism 2. Figure 4 As indicated by the arrow, the gas flows into the second gas port 14, the second gas channel 15 and the retreat chamber 16 in sequence through the gas inlet 21, pushing the piston 3 toward the inlet chamber 13, so that the gas in the inlet chamber 13 flows through the first gas channel 12 and the first gas port 11 in sequence, and then flows out from the second gas outlet 222. Figure 5 The arrow points to the direction to achieve clamping.

[0041] In summary, the utility model provides a nailing device, which reduces labor intensity and ensures nailing quality.
