Description

Technical Field

[0001] This utility model relates to the field of switches for clamp nail guns, and particularly to a switch assembly and a clamp nail gun for clamp nail guns. Background Technology

[0002] In existing barbed wire nail guns, when used for barbed wire application, the nail gun is suspended vertically, with the nailing nozzle 1' and trigger 2' both located at the bottom of the nail gun. Figure 1 As shown. When nailing barbed wire, the worker holds the nail gun to control the nailing position and aims it at the barbed wire. Since the pinky finger is close to the trigger, it is usually used to pull the trigger to fire the nail. However, the pinky finger lacks dexterity and strength, and after prolonged operation, it is easy to miss nails or get nails stuck, reducing production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a switch assembly for a clip nail gun, which changes the pressing position, saves effort, and reduces the occurrence of missing nails and nail jamming.

[0004] The technical problem to be solved by this utility model is to provide a clamp nail gun that includes a switch assembly.

[0005] To solve the above-mentioned technical problems, this utility model provides a switch assembly for a clip nail gun, including a trigger and a switch lever. The trigger includes a pressing part, a connecting part, a transition part, and an actuating part, which are arranged sequentially. The trigger can rotate around the transition part, and the actuating part abuts against the switch lever to drive the switch lever. The length of the connecting part is greater than the length of the lever part.

[0006] As an improvement to the above solution, the pressing part includes a limiting section and a pressing section, the limiting section is located at one end of the pressing section, and the end of the limiting section is higher than one side of the pressing section.

[0007] As an improvement to the above solution, the connecting part includes a clearance section and a connecting section. The clearance section is located at the other end of the pressing section and extends from the pressing section to one side of the pressing section. The clearance section, connecting section, and lever section are connected in sequence.

[0008] As an improvement to the above solution, the lever part includes a receiving section and a lever section, the connecting section, the receiving section and the lever section are connected in sequence, and the adapter part is located at the connection between the connecting section and the receiving section; the lever section abuts against the switch rod.

[0009] As an improvement to the above solution, the actuating section is provided with a limiting groove, and the switch rod is inserted into the limiting groove.

[0010] As an improvement to the above solution, the adapter is a bushing.

[0011] As an improvement to the above solution, the switch lever includes a transmission part, a movable part, and a driving part, which are arranged sequentially. The switch lever can rotate around the movable part, and the lever actuating part and the transmission part abut against each other.

[0012] As an improvement to the above solution, the movable part is a through hole.

[0013] Accordingly, this utility model also provides a clip nail gun, including a gun body and a switch assembly of the above-mentioned clip nail gun mounted on the gun body; The trigger and switch lever are rotatably connected to the gun body.

[0014] As an improvement to the above solution, the gun body is provided with a first rotating shaft, a second rotating shaft and a positioning pin, the trigger is rotatably connected to the gun body through the first rotating shaft, and the switch lever is rotatably connected to the gun body through the second rotating shaft; The locating pin can abut against the connecting part to restrict trigger rotation.

[0015] The following are the beneficial effects of implementing this utility model: 1. The switching assembly of this utility model's clip-on nail gun includes a trigger and a switch lever. The trigger activates the nail gun via the switch lever to drive nails. The switch lever increases the distance between the trigger and the switch rod inside the gun body, thus increasing the distance between the trigger and the gun body and preventing interference between the trigger and the user's hand holding the gun body when the trigger is pulled.

[0016] 2. The connecting part supports the pressing part, positioning it in the upper middle part of the gun body, corresponding to the position of the user's index finger when holding the gun. This allows the user to easily press the pressing part with their index finger to pull the trigger. Compared to existing triggers that use the pinky finger, the index finger offers better flexibility and strength, reducing the occurrence of missed shots and jamming, thus improving production efficiency.

[0017] 3. The length of the connecting part is greater than the length of the trigger, and the distance between the pressing part and the transition part (support point) is also increased compared to the existing design. According to the lever principle, the longer lever arm reduces the force required. Therefore, it requires less effort for the user to press the trigger, reducing labor intensity and minimizing the occurrence of missed nails and jamming. The easier it is for users to press the trigger, thus improving production efficiency. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] See Figure 2-9 This utility model discloses a switch assembly for a clip nail gun, including a trigger 1 and a switch lever 2. The trigger 1 includes a pressing part 11, a connecting part 12, a transition part 13, and an actuating part 14, which are arranged sequentially. The trigger 1 can rotate around the transition part 13, and the actuating part 14 abuts against the switch lever 2 to drive the switch lever 2.

[0021] The length of the connecting part 12 is greater than the length of the lever part 14.

[0022] The following are the beneficial effects of implementing this utility model: 1. The switching assembly of this utility model's clip-on nail gun includes a trigger and a switch lever. The trigger activates the nail gun via the switch lever to drive nails. The switch lever increases the distance between the trigger and the switch rod inside the gun body, thus increasing the distance between the trigger and the gun body and preventing interference between the trigger and the user's hand holding the gun body when the trigger is pulled.

[0023] 2. The connecting part supports the pressing part, positioning it in the upper middle part of the gun body, corresponding to the position of the user's index finger when holding the gun. This allows the user to easily press the pressing part with their index finger to pull the trigger. Compared to existing triggers that use the pinky finger, the index finger offers better flexibility and strength, reducing the occurrence of missed shots and jamming, thus improving production efficiency.

[0024] 3. The length of the connecting part is greater than the length of the trigger, and the distance between the pressing part and the transition part (support point) is also increased compared to the existing design. According to the lever principle, the longer lever arm reduces the force required. Therefore, it requires less effort for the user to press the trigger, reducing labor intensity and minimizing the occurrence of missed nails and jamming. The easier it is for users to press the trigger, thus improving production efficiency.

[0025] like Figure 3 As shown, the pressing part 11 includes a limiting section 111 and a pressing section 112. The limiting section 111 is located at one end of the pressing section 112, and the end of the limiting section 111 is higher than one side of the pressing section 112. The limiting section 111 extends from one side of the pressing section 112. The user presses the pressing section with their index finger to pull the trigger. The pressing section and the index finger are positioned correspondingly to facilitate the user pulling the pressing section with their index finger. The limiting section allows the index finger to quickly find the pressing section and pull it towards the gun body. In other words, the limiting section limits the index finger, allowing it to land accurately and quickly on the pressing section, improving efficiency. The index finger abuts against the side of the pressing section to pull the trigger.

[0026] like Figure 3 As shown, the connecting part 12 includes a clearance section 121 and a connecting section 122. The clearance section 121 is located at the other end of the pressing section 112 and extends from the pressing section 112 to one side of the pressing section 112. The clearance section 121, the connecting section 122 and the lever part 14 are connected in sequence.

[0027] In other words, both the anti-slip section 121 and the limiting section 11 extend towards the same side of the pressing section 112. The anti-slip section and the limiting section work together to limit the index finger from both ends of the pressing section, preventing slippage. This also makes it easier for the index finger to quickly locate the pressing section, improving production efficiency. Simultaneously, the anti-slip section extends from the pressing section towards one side, keeping the connecting section away from the gun body and preventing the connecting section from pinching the hand when the trigger is pulled.

[0028] Preferably, such as Figure 3 As shown, the lever 14 includes a receiving section 141 and a lever section 142. The connecting section 122, the receiving section 141 and the lever section 142 are connected in sequence. The adapter 13 is located at the connection between the connecting section 122 and the receiving section 141. The lever section 142 abuts against the switch rod 2.

[0029] like Figure 7 , 9As shown, the adapter 13 is a bushing, which is fitted around the first rotating shaft 33 of the gun body 3, allowing the trigger 1 to rotate around the first rotating shaft 33. Therefore, the adapter is equivalent to a fulcrum in the lever principle. When the user presses its pressing part, the connecting part is driven, causing the trigger to rotate around the first rotating shaft, and the triggering part is driven to drive the switch rod. Specifically, the receiving section drives the triggering section to move, and the triggering section moves the switch rod. The receiving section plays a transmission role and also a connecting role, so that the setting position of the triggering section can adapt to the position of the switch rod to smoothly drive the switch rod.

[0030] Better, such as Figure 2 As shown, the lever section 142 is provided with a limiting groove 143, and the switch rod 2 is inserted into the limiting groove 143. The limiting groove limits the switch rod, preventing it from moving left or right and disengaging from the trigger, thus causing the trigger to fail to engage.

[0031] Furthermore, such as Figure 4 As shown, the switch lever 2 includes a transmission part 21, a movable part 22, and a drive part 23. The transmission part 21, the movable part 22, and the drive part 23 are arranged in sequence. The switch lever 2 can rotate around the movable part 22. The lever 14 and the transmission part 21 are in contact.

[0032] like Figure 7 , 9 As shown, the movable part 22 is a through hole, through which the switch rod 2 is sleeved on the second rotating shaft 34 of the gun body 3, allowing the switch rod 2 to rotate around the second rotating shaft 34. When the user pulls the trigger, the trigger part and the transmission part abut against each other, moving the switch rod and causing it to rotate. This causes the drive part to abut against the switch pin inside the gun body, thereby changing the gas path inside the gun body and achieving nail driving. Specifically, the transmission part is inserted into the limiting groove to prevent the switch rod from moving left or right and disengaging from the trigger part.

[0033] Accordingly, see Figure 2-9 This utility model also discloses a clip nail gun, including a gun body 3 and a switch assembly of the aforementioned clip nail gun mounted on the gun body 3; the trigger 1 and the switch lever 2 are respectively rotatably connected to the gun body 3. The specific structure of the switch assembly of the clip nail gun is as described above, and will not be repeated here.

[0034] Preferably, such as Figure 7 , 9 As shown, the gun body 3 is provided with a first rotating shaft 33, a second rotating shaft 34 and a positioning pin 35. The trigger 1 is rotatably connected to the gun body 3 through the first rotating shaft 33, and the switch rod 2 is rotatably connected to the gun body 3 through the second rotating shaft 34. The positioning pin 35 can abut against the connecting part 13 to restrict the rotation of the trigger 1.

[0035] like Figure 7 , 9As shown, the adapter 13 is a bushing, which is fitted around the first rotating shaft 33 of the gun body 3, allowing the trigger 1 to rotate around the first rotating shaft 33. The movable part 22 is a through hole, through which the switch rod 2 is fitted around the second rotating shaft 34 of the gun body 3, allowing the switch rod 2 to rotate around the second rotating shaft 34. The positioning pin limits the trigger, preventing the trigger from resetting and causing the index finger to be unable to reach the pressing part, thereby limiting the angle of trigger rotation.

[0036] Specifically, as shown in Figures 7-8, the gun body is provided with a first air chamber 31 and a second air chamber 32. The first air chamber 31 is provided with a first elastic element 4, a sealing element 5, and a switch pin 6. The sealing element 5 is fixed in the first air chamber 31 by the first elastic element 4. Under the action of air pressure in the first air chamber, the switch pin abuts against the sealing element, thereby sealing the first air chamber. When the switch pin is subjected to external force and separates from the sealing element, the first air chamber opens.

[0037] The second air chamber 32 is equipped with a firing pin head 7 and a second elastic element 8. The nail clamp gun also includes a firing pin 9, a nail coiling block 10, and a support member 15. The nail coiling block 10 and the support member 15 are respectively fixed to the gun body 3. The firing pin 9 is connected to the firing pin head 7 and is located between the nail coiling block 10 and the support member 15, allowing it to move between them. When the firing pin moves towards the nail coiling block, it contacts the block, clamping the nail; when the firing pin resets and moves towards the support member, it abuts against the support member, which limits its movement. It should be noted that the air path of the nail clamp gun can adopt existing technology, which will not be described in detail here.

[0038] In the unfired state of this utility model's clamp nail gun: when the air source is connected to the nail gun, the gas flows through the air passage in the gun body 3 to the first air chamber 31. The air pressure in the first air chamber 31 pushes the switch pin 6 to contact the switch lever 2, and the switch lever 2 contacts the trigger 1. At the same time, the positioning pin 35 limits the trigger 1, so that the clamp nail gun is in the initial ready-to-fire state, such as... Figure 5-7 As shown.

[0039] The firing state of this utility model's clamp nail gun is as follows: When the air source is connected to the nail gun, the gas enters the first air chamber 31 through the air passage inside the gun body 3. When the index finger is on the trigger and the pressing part 11 is pressed to the limit of contact with the gun body 3, according to the lever principle, the trigger 1 rotates, and the actuating section 142 moves the transmission part 21 of the switch lever 2, causing the switch lever 2 to rotate around the second rotating shaft 34. At the same time, the driving part 23 of the switch lever 2 pushes up the switch top rod 6, causing the switch top rod 6 and the sealing part 5 to separate. The gas in the first air chamber 31 is discharged from the gap between the switch top rod 6 and the sealing part 5, allowing the gas from the air source to enter the second air chamber 32. The air pressure in the second air chamber 32 increases instantaneously, pushing the firing pin head 7 to move. The firing pin head 7 pushes the firing pin 9 towards the nail coiling block 10. The firing pin 9 pushes the nail to the nail coiling block 10 and clamps the nail to form a shape, thus realizing nailing. Figure 8-9 As shown.

[0040] This utility model of a clip-on nail gun restores its initial state as follows: When the air source is connected to the nail gun, the gas flows through the air passage in the gun body 3 to the first air chamber 31. When the trigger 1 is released, the air pressure in the first air chamber 31 pushes the switch pin 6 back to its original position, and it contacts the switch lever 2. The switch lever 2 and the trigger 1 then contact each other, and the trigger 1 is reset under the limiting action of the positioning pin 35. At the same time, the gas in the second air chamber 32 is discharged from the rear cover of the gun body 3. The firing pin head 7 is reset under the action of the second elastic element 8, and at the same time, the firing pin head 74 pulls the firing pin 9. The firing pin 9 is reset under the limiting action of the support element 15. Figure 6 As shown.

[0041] In summary, this utility model provides a switch assembly and a clamping nail gun that change the pressing position, saving effort and reducing the occurrence of missing nails and nail jamming.

[0042] 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.
