[0002] A sofa is a multi-seat chair with cushions. It has a backrest with springs or thick foam, and armrests on both sides; it is a type of upholstered furniture.

[0003] During sofa manufacturing, nail guns are used to secure the panels together and the upholstery. Currently, the spacing of the nails is determined by the worker's experience and intuition. This method makes it difficult to guarantee the quality of the sofa's construction, resulting in significant quality differences between different sofas. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a nail gun auxiliary device to solve the technical problem that current nailing methods rely entirely on workers' experience, making it difficult to guarantee sofa quality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A nail gun auxiliary device includes two first force-bearing plates and a second force-bearing plate connected between them. One end of one of the first force-bearing plates is fixedly equipped with a protective cover. A first connecting shaft is rotatably mounted inside the protective cover. A friction wheel and a first sprocket are fixedly mounted on the first connecting shaft. The friction wheel contacts the material. A second connecting shaft is rotatably mounted inside the protective cover. A second sprocket and a transmission disc are fixedly mounted on the second connecting shaft. A chain is provided between the first sprocket and the second sprocket. A plurality of first drive rods are rotatably mounted on the transmission disc. A second drive rod is rotatably mounted inside one of the first force-bearing plates. The rotation of the first drive rod drives the second drive rod to rotate and activates the nail gun switch.

[0007] Working principle:

[0008] The nail gun is fixed between two first load-bearing plates, so that the friction wheel contacts the plate. The entire device moves along the plate, and the friction wheel rotates in contact with the plate. The friction wheel drives the first sprocket to rotate through the first connecting shaft. The first sprocket drives the second sprocket to rotate through the chain. The second sprocket drives the transmission disc to rotate through the second connecting shaft. The transmission disc drives the first drive rod to rotate. The first drive rod drives the second drive rod to rotate intermittently. The intermittent rotation of the second drive rod causes the nail gun to open intermittently, so that the nail gun opens to nail into the plate every time the friction wheel rolls a certain distance.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The nail gun is turned on intermittently according to the distance the friction wheel rolls, so that the distance between two nails can be controlled, ensuring the stability of the sofa's quality;

[0011] 2. The worker only needs to move the entire equipment to fit the board, without having to constantly press the nail gun switch, which reduces the worker's workload. Attached Figure Description

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] like Figure 1 and Figure 3As shown, a nail gun auxiliary device is used for the Tengya GSN40B gas gun. It includes two first force-bearing plates 14, with a second force-bearing plate 12 connected between them. One end of each first force-bearing plate 14 is fixed with a protective cover 24. A first connecting shaft 17 is rotatably mounted inside the protective cover 24. A friction wheel 19 and a first sprocket 39 are fixed on the first connecting shaft 17. The friction wheel 19 contacts the board material. The nail gun is intermittently activated based on the rolling distance of the friction wheel 19, thereby controlling the distance between two nails and ensuring the stability of the sofa's quality. A second connecting shaft 23 is rotatably mounted inside the protective cover 24. A second sprocket 22 and a transmission disc 33 are fixed on the second connecting shaft 23. A chain 21 connects the first sprocket 39 and the second sprocket 22. Several first drive rods 35 are rotatably mounted on the transmission disc 33. Preferably, as shown... Figure 3 As shown, in this embodiment, there are eight first drive rods 35. Users can rotate and adjust the first drive rods 35 according to actual needs, thereby adjusting the density of nailing by the nail gun. A second drive rod 27 is rotatably installed inside one of the first load-bearing plates 14. The rotation of the first drive rods 35 drives the second drive rod 27 to rotate and activate the nail gun switch. Workers only need to move the entire device to fit the board, eliminating the need for continuous pressing of the nail gun switch, thus reducing the worker's workload.

[0020] The nail gun is fixed between two first force-bearing plates 14, so that the friction wheel 19 contacts the plate. The entire device moves along the plate, and the friction wheel 19 rotates in contact with the plate. The friction wheel 19 drives the first sprocket to rotate through the first connecting shaft 17. The first sprocket drives the second sprocket 22 to rotate through the chain 21. The second sprocket 22 drives the transmission disc 33 to rotate through the second connecting shaft 23. The transmission disc 33 drives the first drive rod 35 to rotate. The first drive rod 35 drives the second drive rod 27 to rotate intermittently. The intermittent rotation of the second drive rod 27 causes the nail gun to open intermittently, so that the nail gun opens and nails into the plate every time the friction wheel 19 rolls a certain distance.

[0021] A third force plate 16 is fixed between the two first force plates 14. The third force plate 16 is perpendicular to the second force plate 12. A nail interface 15 is provided through the third force plate 16. The exit of the nail gun is opposite to the nail interface 15.

[0022] One end of the first force-bearing plate 14 away from the protective cover 24 is threadedly connected to a screw rod 11 with a nut. The screw rod 11 passes through one end of the first force-bearing plate 14 and is rotatably connected to an abutment plate 13. The abutment plate 13 cooperates with another first force-bearing plate 14 to fix the nail gun. When the screw rod 11 is rotated, the screw rod 11 drives the abutment plate 13 to move, and the movement of the abutment plate 13 fixes the nail gun.

[0023] A first mounting plate 20 is fixed inside the protective cover 24. A first connecting shaft 17 is rotatably mounted at one end of the first mounting plate 20. A contact port 18 is opened on one side of the protective cover 24, and the friction wheel 19 abuts against the plate through the contact port 18.

[0024] A second mounting plate 10 is fixed inside the protective cover 24. A second connecting shaft 23 rotatably passes through the second mounting plate 10. A second sprocket 22 and a transmission disc 33 are located on both sides of the second mounting plate 10. A plurality of first storage slots 36 are evenly circumferentially opened at one end of the transmission disc 33. The number of first storage slots 36 is the same as that of the first drive rods 35, which is eight in total. A third connecting shaft 34 is fixed inside the first storage slots 36. The first drive rods 35 are rotatably mounted on the third connecting shaft 34. When it is necessary to adjust the nail spacing, a certain number of first drive rods 35 are rotated appropriately so that the first drive rods 35 do not abut against the second drive rods 27 after rotation, such as rotating four first drive rods 35 at intervals.

[0025] like Figure 2 As shown, the first force-bearing plate 14 has a second storage groove 37 through it. A fourth connecting shaft 30 is fixedly installed in the second storage groove 37. The second drive rod 27 is rotatably mounted on the fourth connecting shaft 30. A torsion spring 32 is provided between the second drive rod 27 and the fourth connecting shaft 30.

[0026] The second drive rod 27 has a fifth connecting shaft 26 rotatably mounted on one end facing away from the transmission disk 33. A sixth connecting shaft 25 is rotatably mounted on one side of the fifth connecting shaft 26. A third drive rod 28 is rotatably mounted on the sixth connecting shaft 25. A connecting groove 29 is provided through the third drive rod 28. A blocking plate 38 is fixedly mounted on the end of the second drive rod 27 facing away from the transmission disk 33. The blocking plate 38 is used to restrict the rotation of the third drive rod 28. With the fifth connecting shaft 26 as the rotation center, the third drive rod 28 is rotated 90 degrees so that the blocking plate 38 can pass through the connecting groove 29. That is, the third drive rod 28 can be rotated with the sixth connecting shaft 25 as the rotation center. By rotating the third drive rod 28, it is convenient to fix the nail gun.

[0027] Working principle:

[0028] Rotate the third drive rod 28 90 degrees around the fifth connecting shaft 26 as the rotation center, and then rotate the third drive rod 28 again around the sixth connecting shaft 25 as the rotation center, so that the blocking plate 38 passes through the connecting groove 29, placing the nail gun between the two first force-bearing plates 14. Rotate the screw 11, which drives the abutment plate 13 closer to the nail gun, thereby fixing the nail gun. Rotate the third drive rod 28, moving it to the side opposite to the nail gun switch, so that the friction wheel 19 is in contact with the plate and moved along the direction where nailing is required. The friction wheel 19 rotates, and the friction wheel 19 drives the first sprocket 39 to rotate via the first connecting shaft 17. The first sprocket 39 drives the second sprocket 22 to rotate via the chain 21. The second sprocket 22 drives the transmission disc 33 to rotate via the second connecting shaft 23. The transmission disc 33 drives the first drive rod 35 to rotate. The first drive rod 35 drives the second drive rod 27 to rotate. The second drive rod 27 drives the third drive rod 28 to rotate. The rotation of the third drive rod 28 contacts the nail gun switch, causing the nail gun switch to close and the nail gun to drive nails into the board.
