Description

Technical Field

[0001] This utility model relates to the field of gun nozzles, and in particular to a gun nozzle device and a nail gun. Background Technology

[0002] Existing nail gun nozzles consist of a nozzle body and a nozzle panel. The nozzle body has a nail ejection channel. The nail feed body pushes the nail into the ejection channel through a through hole at the bottom of the nozzle, and then the nail-driving pin drives the nail out of the ejection channel. The nozzle panel covers the top of the nail ejection channel, which can seal the nail ejection channel to prevent the nail from being driven out in other directions, and at the same time guide the movement of the nail. Currently, the nozzle panel is fixed to the nozzle body with screws. If a nail gets stuck, the screws need to be unscrewed to open the nozzle panel, which is time-consuming, laborious, and inconvenient.

[0003] Some designs have a snap-on plate on the side of the nozzle body to hold the nozzle panel in place, ensuring it covers the nail delivery channel. However, there is often a gap between the snap-on plate and the nozzle panel, causing the nozzle panel to wobble on the nozzle body and preventing it from being effectively secured, thus affecting the nailing effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a nozzle device that is easy to disassemble and has a reliable and stable connection.

[0005] The technical problem to be solved by this utility model is to provide a nail gun equipped with the nozzle device.

[0006] To solve the above-mentioned technical problems, this utility model provides a gun nozzle device, including a gun nozzle, a gun nozzle panel and a quick-release mechanism, wherein the gun nozzle is provided with a nail ejection channel and the quick-release mechanism is installed on the gun nozzle panel;

[0007] The nozzle is provided with a limiting component, and the limiting component is provided with a first limiting inclined surface; the quick release mechanism includes a quick release part that is movably connected to the nozzle panel, and the quick release part is provided with a first positioning inclined surface;

[0008] The quick-release component is engaged on the limiting component, and the first limiting inclined surface and the first positioning inclined surface abut against each other, so that the positions of the nozzle and the nozzle panel are relatively fixed, thereby closing the nail ejection channel;

[0009] By driving the quick-release mechanism, the quick-release mechanism and the limiting component are separated, thereby opening the nail ejection channel.

[0010] As an improvement to the above solution, the quick-release mechanism further includes a reset component, which includes an elastic member. The two ends of the elastic member abut against the quick-release component and the nozzle panel, respectively, so that the first limiting slope and the first positioning slope abut against each other.

[0011] As an improvement to the above solution, the reset assembly further includes a guide rod, and the quick-release component and the elastic component are both sleeved on the guide rod.

[0012] As an improvement to the above solution, the nozzle panel is provided with a first positioning seat and a second positioning seat, the two ends of the guide rod are respectively mounted on the first positioning seat and the second positioning seat, and the quick-release component and the elastic component are located between the first positioning seat and the second positioning seat.

[0013] As an improvement to the above solution, the first positioning seat is provided with a mounting hole, and the second positioning seat is provided with a mounting groove; one end of the guide rod passes through the mounting hole, and the other end is inserted into the mounting groove;

[0014] The first positioning seat is provided with a positioning hole, which is connected to the mounting hole; the reset assembly also includes a positioning pin, which is installed in the positioning hole and passes through the guide rod to fix the guide rod to the first positioning seat.

[0015] As an improvement to the above solution, the quick-release component includes a positioning part, and the first positioning inclined surface is disposed on the positioning part;

[0016] The limiting component includes a limiting post with a limiting notch, and a first limiting inclined surface is disposed within the limiting notch; the positioning part is inserted into the limiting notch through an elastic component, and the first limiting inclined surface and the first positioning inclined surface abut against each other.

[0017] As an improvement to the above solution, the limiting component further includes a limiting seat fixedly installed on the nozzle, and the limiting seat is provided with a second limiting inclined surface;

[0018] The nozzle panel is provided with a second positioning slope, and the second limiting slope and the second positioning slope abut against each other.

[0019] As an improvement to the above solution, the quick-release mechanism is located between the limiting post and the limiting seat;

[0020] The first limiting slope is inclined downward from the side closer to the quick-release mechanism to the side farther away from the quick-release mechanism, and the second limiting slope is inclined downward from the side closer to the quick-release mechanism to the side farther away from the quick-release mechanism.

[0021] As an improvement to the above solution, the nozzle panel is provided with a limiting platform, which is locked onto the limiting seat.

[0022] Accordingly, this utility model also provides a nail gun, including a gun body, a nail feeding mechanism and the aforementioned nozzle device, wherein the nozzle device is connected to the gun body and the nail feeding mechanism respectively.

[0023] Implementing this utility model has the following beneficial effects:

[0024] This utility model's nozzle device features a limiting component on the nozzle, with a first limiting inclined surface. A quick-release mechanism with a first positioning inclined surface is also provided on the nozzle panel. When the quick-release mechanism engages with the limiting component, it limits the nozzle panel, preventing it from detaching from the nozzle and keeping it closed to seal the nail delivery channel, allowing for nailing operations. Simultaneously, to ensure a tight connection between the nozzle and the nozzle panel and prevent the nozzle panel from wobbling and affecting the nailing effect, the first limiting inclined surface and the first positioning inclined surface abut against each other. This interaction generates potential energy for the nozzle panel to move towards the nozzle, ensuring the nozzle panel remains firmly against the nozzle without wobbling, resulting in a reliable and stable connection.

[0025] When a nail gets stuck, the user simply needs to drive the quick-release mechanism away from the limiting component to separate them. Then, the nozzle panel can be pulled out to open the nail ejection channel and remove the stuck nail. The disassembly operation is simple, convenient, and saves time and effort.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0036] See Figure 1-9 This utility model discloses a nozzle device 100, including a nozzle 1, a nozzle panel 2, and a quick-release mechanism. The nozzle 1 is provided with a nail ejection channel 11, and the quick-release mechanism is installed on the nozzle panel 2. The nozzle panel 2 closes or opens the nail ejection channel 11 through the quick-release mechanism.

[0037] The nozzle 1 is provided with a limiting component, and the limiting component is provided with a first limiting inclined surface 121; the quick release mechanism includes a quick release part 3 that is movably connected to the nozzle panel 2, and the quick release part 3 is provided with a first positioning inclined surface 321.

[0038] The quick-release component 3 is engaged on the limiting component, and the first limiting inclined surface 121 and the first positioning inclined surface 321 abut against each other, so that the positions of the nozzle 1 and the nozzle panel 2 are relatively fixed, thereby closing the nail outlet channel 11.

[0039] By driving the quick-release component 3, the quick-release component 3 and the limiting component are separated, thereby opening the nail outlet channel 11.

[0040] This utility model's nozzle device features a limiting component on the nozzle, with a first limiting inclined surface. A quick-release mechanism with a first positioning inclined surface is also provided on the nozzle panel. When the quick-release mechanism engages with the limiting component, it limits the nozzle panel, preventing it from detaching from the nozzle and keeping it closed to seal the nail delivery channel, allowing for nailing operations. Simultaneously, to ensure a tight connection between the nozzle and the nozzle panel and prevent the nozzle panel from wobbling and affecting the nailing effect, the first limiting inclined surface and the first positioning inclined surface abut against each other. This interaction generates potential energy for the nozzle panel to move towards the nozzle, ensuring the nozzle panel remains firmly against the nozzle without wobbling, resulting in a reliable and stable connection.

[0041] When a nail gets stuck, the user simply needs to drive the quick-release mechanism away from the limiting component to separate them. Then, the nozzle panel can be pulled out to open the nail ejection channel and remove the stuck nail. The disassembly operation is simple, convenient, and saves time and effort.

[0042] Furthermore, the quick-release mechanism also includes a reset component. The reset component not only helps the quick-release component to automatically reset, but also ensures that the quick-release component is always stuck on the limiting component, so that the first limiting slope and the first positioning slope always remain in contact, thereby ensuring that the nozzle panel closes the nail outlet channel during the nailing process and ensuring the nailing effect.

[0043] Specifically, such as Figure 1-5 As shown in Figures 7-8, the reset assembly includes an elastic component 4. Both ends of the elastic component 4 abut against the quick-release piece 3 and the nozzle panel 2, respectively, causing the first limiting inclined surface 121 and the first positioning inclined surface 321 to abut against each other. The elastic component 4 is a spring. Under the elastic force of the elastic component, the quick-release piece moves towards the limiting assembly, causing the first limiting inclined surface and the first positioning inclined surface to abut against each other. The first limiting inclined surface guides the first positioning inclined surface, causing the nozzle panel and the quick-release mechanism to move diagonally downwards, i.e., towards the nozzle, so that the nozzle panel is tightly locked onto the nozzle, conforming to the nozzle and effectively sealing the nail ejection channel.

[0044] It should be noted that the nozzle panel 2 is used to close the top of the nail ejection channel 11, while the two ends of the nail ejection channel are open. The firing pin can enter the nail ejection channel from one end and eject the nails from the other end of the nail ejection channel.

[0045] Preferably, such as Figure 1-5 As shown in Figure 7, the reset assembly also includes a guide rod 5, and the quick-release piece 3 and the elastic component 4 are both sleeved on the guide rod 5. The guide rod 5 is mounted on the nozzle panel 2. The guide rod guides the movement of the quick-release piece and the elastic component, ensuring that they move in the predetermined direction without deviating, thereby ensuring that the nozzle panel is locked on the nozzle, thus guaranteeing the nailing effect.

[0046] Better, such as Figure 1-5 As shown in Figures 7-8, the nozzle panel 2 is provided with a first positioning seat 21 and a second positioning seat 22. The two ends of the guide rod 5 are respectively mounted on the first positioning seat 21 and the second positioning seat 22. The quick-release component 3 and the elastic component 4 are located between the first positioning seat 21 and the second positioning seat 22. The guide rod is mounted on the first and second positioning seats, suspending the quick-release component and the elastic component, allowing them to slide back and forth along the guide rod. The first and second positioning seats support the guide rod, ensuring the reliability and stability of the quick-release component's movement.

[0047] Specifically, such as Figure 3 As shown, the first positioning seat 21 has a mounting hole 211, and the second positioning seat 22 has a mounting groove 221. One end of the guide rod 5 passes through the mounting hole 211, and the other end is inserted into the mounting groove 221. The axes of the mounting hole 211 and the mounting groove 221 are on the same axis, ensuring the stability and reliability of the guide rod installation, and making the guide rod tightly and reliably connected to the first positioning seat and the second positioning seat respectively.

[0048] Better, such as Figure 3As shown, the first positioning seat 21 has a positioning hole 212, which communicates with the mounting hole 211. The axes of the positioning hole 212 and the mounting hole 211 are perpendicularly connected to each other. The reset assembly also includes a positioning pin 6, which is installed in the positioning hole 212 and passes through the guide rod 5 to fix the guide rod 5 to the first positioning seat 21, thereby locking the guide rod onto the first and second positioning seats. The positioning pin 6 is a cotter pin, which is easy to install. The positioning pin ensures that the guide rod is installed on the first and second positioning seats, preventing the guide rod from dislodging from the mounting hole and mounting groove.

[0049] Furthermore, such as Figure 4 , 7 As shown in Figure 8, the quick-release component includes a positioning part 32, and the first positioning inclined surface 321 is disposed on the positioning part 32. The quick-release component 3 also includes a handle part 31, which allows the user to move the handle part to separate the quick-release component from the limiting component, so that the nozzle panel can be removed from the nozzle and the nail ejection channel can be opened.

[0050] Specifically, such as Figure 1-2 As shown in Figures 4-6, the limiting component includes a limiting post 12, which has a limiting notch 122. The first limiting inclined surface 121 is disposed within the limiting notch 122. The positioning part 32 is inserted into the limiting notch 122 via an elastic member 4, and the first limiting inclined surface 121 and the first positioning inclined surface 321 abut against each other. The quick-release piece is inserted into the limiting notch under the elastic force of the elastic member, and the first limiting inclined surface and the first positioning inclined surface abut against each other to limit the quick-release piece, fixing it on the limiting post, thereby fixing the nozzle panel on the nozzle. The first limiting inclined surface and the first positioning inclined surface interact to press the nozzle panel tightly against the nozzle.

[0051] Preferably, there are two limiting posts 12, symmetrically arranged on both sides of the nozzle 1; and two positioning parts 32, symmetrically arranged on both sides of the quick-release part 3. The limiting posts 12 and the positioning parts 32 are arranged in a one-to-one correspondence.

[0052] Preferably, such as Figure 1-8 As shown, the limiting assembly also includes a limiting seat 13 fixedly installed on the nozzle 1, the limiting seat 13 having a second limiting inclined surface 131; the nozzle panel 2 has a second positioning inclined surface 23, the second limiting inclined surface 131 and the second positioning inclined surface 23 abutting against each other. The cooperation between the second limiting inclined surface and the second positioning inclined surface makes the other end of the nozzle panel also press tightly against the nozzle, further making the entire nozzle panel press tightly against the nozzle.

[0053] Among them, such as Figure 1-5 As shown, the quick-release mechanism is located between the limiting post 12 and the limiting seat 13; Figure 3-4As shown in Figures 6-8, the first limiting slope 121 is inclined downwards from the side closer to the quick-release mechanism to the side farther away from the quick-release mechanism, and the second limiting slope 131 is inclined downwards from the side closer to the quick-release mechanism to the side farther away from the quick-release mechanism. That is, the inclination directions of the first limiting slope 121 and the second limiting slope 131 are opposite. Correspondingly, the inclination directions of the first positioning slope 321 and the first limiting slope 121 are the same, and the inclination directions of the second positioning slope 23 and the second limiting slope 131 are the same. That is, the inclination directions of the first positioning slope 321 and the second positioning slope 23 are opposite. Under the action of the elastic component, the quick-release component moves towards the limiting post and abuts against the limiting post through the limiting slope, causing the quick-release component to move towards the nozzle. At the same time, a reaction force is applied to the second positioning seat, i.e., the nozzle panel, causing the second positioning slope and the second limiting slope to abut against each other, causing the quick-release component to move towards the nozzle. Therefore, under the action of the two sets of inclined planes, both ends of the nozzle panel move towards the nozzle, closely adhering to the nozzle and not wobbling, ensuring the nailing effect.

[0054] Better, such as Figure 5 , 8 As shown, the nozzle panel 2 is provided with a limiting platform 24, which is engaged with the limiting seat 13. The limiting platform and the limiting seat cooperate to limit and position the nozzle panel, ensuring the accuracy of the nozzle panel's installation position and improving installation efficiency.

[0055] During installation, first insert the nozzle panel 2 under the limiting seat 13, so that the second limiting slope 131 and the second positioning slope 23 abut against each other. Then, move the quick release piece 3 to compress the elastic component 4, so that the nozzle panel 2 is completely attached to the nozzle 1. Finally, release the quick release piece 3, and the elastic component 4 returns to its original position, allowing the quick release piece 3 to be inserted into the limiting notch 122 of the limiting post 12 under the action of the elastic component 4. At the same time, the first limiting slope 121 and the first positioning slope 321 abut against each other, thereby locking the nozzle panel 2 onto the nozzle 1.

[0056] Accordingly, see Figure 1-9 This utility model also discloses a nail gun, including a gun body 200, a nail feeding mechanism 300, and the aforementioned nozzle device 100, wherein the nozzle device 100 is connected to both the gun body 200 and the nail feeding mechanism 300. The specific structures of the gun body 200, the nail feeding mechanism 300, and the nozzle device 100 can adopt existing technical structures and will not be described in detail here. The specific structure of the nozzle device is as described above and will not be repeated here.

[0057] In summary, this utility model provides a nozzle device and a nail gun that are easy to disassemble and have a reliable and stable connection.

[0058] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
