[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] Example 1

[0036] This embodiment discloses a spring assembly mechanism for a forklift switch. Figure 1 A spring assembly mechanism for a forklift switch includes a support frame 1, two feed pipes 11 and a limiting structure 2. The limiting structure 2 is arranged on the support frame 1, and the two feed pipes 11 are both arranged on the limiting structure 2.

[0037] Reference Figure 1 and Figure 2 The limiting structure 2 includes a limiting driving member 21, a limiting plate 22, two first limiting rods 23 and two second limiting rods 24. The limiting driving member 21 includes a limiting cylinder, which is fixedly connected to the support frame 1. The limiting plate 22 is fixedly connected to the driving shaft of the limiting cylinder, and the limiting cylinder drives the limiting plate 22 to reciprocate. A vertical plate 221 is integrally formed on the surface of the limiting plate 22, and the vertical plate 221 extends in a direction perpendicular to the length of the limiting plate 22. A connecting hole 222 for inserting two feeding pipes 11 is opened on the surface of the limiting plate 22, and the connecting hole 222 extends along the length of the limiting plate 22.

[0038] Reference Figure 2 The vertical plate 221 has two first limiting holes 223 formed on its surface. The first limiting holes 223 are for inserting the first limiting rod 23. The vertical plate 221 has two second limiting holes 224 formed on its surface. The second limiting holes 224 communicate with the connecting hole 222 and extend to the limiting plate 22. The second limiting holes 224 are for inserting the second limiting rod 24.

[0039] Reference Figure 2The limiting plate 22 is provided with a fastening assembly 3, which includes a plurality of fastening bolts 31. The fastening bolts 31 can be threadedly connected to the limiting plate 22 or the vertical plate 221. When the first limiting rod 23 is inserted into the first limiting hole 223, the fastening bolts 31 are threadedly connected to the vertical plate 221, allowing the fastening bolts 31 to abut the first limiting rod 23, making it difficult for the first limiting rod 23 to disengage from the first limiting hole 223, and one end of the first limiting rod 23 is located in the connecting hole 222. When the second limiting rod 24 is inserted into the second limiting hole 224, the fastening bolts 31 are threadedly connected to the limiting plate 22, allowing the fastening bolts 31 to abut the second limiting rod 24, making it difficult for the second limiting rod 24 to disengage from the second limiting hole 224, and one end of the second limiting rod 24 is now located in the connecting hole 222.

[0040] Reference Figure 2 When the limiting cylinder drives the limiting plate 22 to move, the first limiting rod 23 is inserted into the feed pipe 11. At this time, the second limiting rod 24 is not inserted into the feed pipe 11, and the installation spring located between the first limiting rod 23 and the second limiting rod 24 can fall from the feed pipe 11; when the limiting cylinder drives the limiting plate 22 to move, the second limiting rod 24 is inserted into the feed pipe 11. At this time, the first limiting rod 23 is not inserted into the feed pipe 11, and the installation spring above the first limiting rod 23 falls, and the installation spring is restricted by the second limiting rod 24, so that the installation spring cannot continue to move in the feed pipe 11, thereby realizing the sequential falling of the installation springs in the feed pipe 11.

[0041] Reference Figure 1 The support frame 1 is provided with a fixed driving member 25, which includes a fixed cylinder. The fixed cylinder's drive shaft is fixedly connected to a fixed seat 251, and the fixed seat 251 is fixedly connected to eight discharge pipes 26. The fixed cylinder can drive the fixed seat 251 to move toward the housing, allowing the discharge pipes 26 to communicate with the installation slot in the housing, so that the installation spring can fall smoothly into the housing.

[0042] Reference Figure 3 A mobile drive member 27 is fixedly connected to the support frame 1. The mobile drive member 27 includes a mobile motor 272, a mobile turntable 273, and a mobile bar 274. The mobile motor 272 is fixedly connected to the support frame 1, the mobile turntable 273 is fixedly connected to the drive shaft of the mobile motor 272, one end of the mobile bar 274 is rotatably connected to the mobile turntable 273, and the other end of the mobile bar 274 is rotatably connected to the mobile seat 271. Both feed pipes 11 are fixedly connected to the mobile seat 271, which is located on the side of the discharge pipe 26 facing the feed pipe 11. When the mobile seat 271 moves, the discharge pipe 26 and the feed pipe 11 can be connected to each other.

[0043] Reference Figure 3When the moving motor 272 is started, the moving motor 272 drives the moving seat 271 to move horizontally through the moving turntable 273 and the moving bar 274, so that the feed pipe 11 and different discharge pipes 26 are connected, so that the installation spring can enter the different discharge pipes 26 in turn, and the installation spring can be smoothly placed in the shell.

[0044] Reference Figure 1 A discharge air outlet member 28 is fixedly connected to the support frame 1. Two discharge pipes 281 are fixedly connected to the discharge air outlet member 28. Each discharge pipe 281 is connected to a different discharge pipe 26. The discharge pipes 281 are located on the side of the feed pipe 11 away from the limit plate 22. The discharge air outlet member 28 can blow air into the discharge pipes 281. Because the discharge pipes 281 and the discharge pipe 26 are connected, the installation spring can fall smoothly into the discharge pipe 26.

[0045] The implementation principle of Example 1 is: the limiting cylinder drives the limiting plate 22 to move, so that the first limiting rod 23 abuts the installation spring. At this time, the second limiting rod 24 does not abut the installation spring, allowing the installation spring to fall smoothly. At the same time, the discharge air outlet part 28 blows gas through the discharge pipe 281, allowing the installation spring to move smoothly from the feed pipe 11 to the discharge pipe 26, and the fixed cylinder drives the fixed seat 251 to move, so that the discharge pipe 26 and the installation groove are connected, so that the installation spring can fall smoothly into the shell.

[0046] Example 2

[0047] Reference Figure 4 and Figure 5 This embodiment differs from Embodiment 1 in that the fastening assembly 3 includes a fastening plate 35 and a stop plate 34. The second limiting hole 224 extends through the surface of the limiting plate 22, and the limiting plate 22 is provided with a groove 32 that communicates with the second limiting hole 224. The fastening plate 35 is inserted into the groove 32, thereby preventing the second limiting rod 24 from detaching from the limiting plate 22 in the direction in which the second limiting hole 224 extends.

[0048] Reference Figure 5 The fastening plate 35 has a through-hole 33 formed on its surface. A moving block 331 is slidably connected to the through-hole 33. A fastening spring 332 is fixedly connected to the surface of the moving block 331. A fastening block 333 is fixedly connected to the surface of the fastening spring 332 away from the moving block 331. When the fastening plate 35 is inserted into the groove 32, the fastening spring 332 drives the fastening block 333 toward the second limiting hole 224, allowing the fastening block 333 to abut the second limiting rod 24. At this time, the moving block 331 partially protrudes from the through-hole 33.

[0049] Reference Figure 5The stop plate 34 slides on the limiting plate 22. A moving groove 341 is formed on the surface of the stop plate 34 for the moving block 331 to be inserted into. When the fastening plate 35 is inserted into the moving groove 341, the fastening block 333 abuts the second limiting rod 24, and the moving block 331 can be inserted into the moving groove 341. At this time, the fastening spring 332 is in a compressed state.

[0050] Reference Figure 5 The stop plate 34 has an operating hole 342 connected to the movable groove 341. An operating bar 343 is slidably connected to the operating hole 342. The operating bar 343 can be inserted into the movable groove 341. When the operating bar 343 is inserted into the movable groove 341, the operating bar 343 can drive the movable block 331 to disengage from the movable groove 341. At this time, the stop plate 34 can slide on the limit plate 22.

[0051] The implementation principle of Example 2 is as follows: the staff places the fastening plate 35 in the movable groove 341, and allows the fastening spring 332 to drive the fastening block 333 to abut against the second limiting rod 24. At this time, the staff presses the movable block 331, and the staff slides the stop plate 34 to allow the movable block 331 to be inserted into the movable groove 341, thereby realizing the limiting of the fastening plate 35 by the stop plate 34.
