Technical Field
[0001] This application relates to the field of industrial washing machines, and more particularly to a switch structure and an industrial washing machine. Background Technology
[0002] An industrial washing machine is a specialized washing device primarily used for cleaning various types of clothing and textiles.
[0003] In related technologies, industrial washing machines include a body and a door. The door is rotatably connected to one side of the body, and the washing machine is opened and closed by rotating the door. A locking block is fixedly connected to the body, and a latch is rotatably connected to the door. When the industrial washing machine is closed, rotating the latch engages with the locking block, restricting the door's rotation and ensuring the normal operation of the washing machine.
[0004] However, in practical applications, industrial washing machines are prone to shaking during operation, which can cause the latch and locking block to loosen, resulting in the door rotating when opening and closing, thus affecting the normal operation of the industrial washing machine. Therefore, improvements are needed. Utility Model Content
[0005] In order to limit the rotation of the opening and closing door and ensure the normal operation of industrial laundry, this application provides a switch structure.
[0006] The switch structure provided in this application adopts the following technical solution:
[0007] A switch structure includes a body, a switch door, and a fastening assembly; the switch door is rotatably connected to one side of the body; the fastening assembly includes a fastening handle, a latch, and a locking block; one end of the fastening handle is rotatably connected to the side of the switch door away from the body, the latch is rotatably connected to the rotatable end of the fastening handle, and the locking block is located on the side of the body near the switch door, with the latch engaging with the locking block.
[0008] By adopting the above technical solution, in practical applications, the operator holds the fastening handle to drive the door opening and closing and the fastening handle to rotate. After rotating to the appropriate position, the latch engages with the locking block. Then, the fastening handle is rotated in the opposite direction. Since the latch is connected to the fastening handle, the latch is more stably locked to the locking block, which minimizes the possibility of the latch and the locking block loosening during the operation of the industrial washing machine. This restricts the rotation of the door opening and closing, thus ensuring the normal operation of the industrial washing machine.
[0009] Preferably, the fastening assembly further includes a mounting component, which includes a mounting bolt and a mounting nut. The fastening handle is located in one end of the latch, and one end of the mounting bolt passes through the latch and the fastening handle and is threadedly connected to the mounting nut.
[0010] By adopting the above technical solution, and by setting mounting bolts and mounting nuts, a rotational connection between the latch and the fastening handle can be achieved. Furthermore, by rotating the mounting nuts, the damping between the latch and the fastening handle can be adjusted, allowing the latch to be more stably locked onto the locking block.
[0011] Preferably, the fastening assembly further includes a limiting plate, a mounting shell, a limiting post, and a spring. The limiting plate is disposed on the fastening handle and has a limiting hole. The mounting shell is disposed on the switch door, and the fastening handle is rotatably connected to the mounting shell. The limiting post and the spring are disposed in the mounting shell. The limiting post extends out of the mounting shell under the drive of the spring, and the limiting post matches the limiting hole.
[0012] By adopting the above technical solution, by setting a limiting plate, mounting shell, limiting post and spring, rotating the fastening handle makes the limiting plate close to the limiting post, then pressing the limiting post, the limiting post compresses the spring, and then continuing to rotate the fastening handle, so that the limiting post is inserted into the limiting hole under the drive of the spring, so as to restrict the rotation of the fastening handle, further restrict the loosening between the latch and the locking block, thereby further ensuring the stability of the industrial washing machine operation.
[0013] Preferably, the fastening assembly further includes a fastening bolt, the limiting plate has a sliding hole and a relief groove, the fastening handle is slidably connected to the sliding hole, the relief groove is connected to the sliding hole, and the fastening bolt is threadedly connected to the relief groove of the limiting plate to shorten the width of the relief groove.
[0014] By adopting the above technical solution, by setting fastening bolts and sliding the limiting plate, the position of the limiting plate is adjusted so that the limiting post can be inserted into the limiting hole. By rotating the fastening bolts, the width of the relief groove is shortened so that the limiting plate is clamped to the fastening handle to fix the sliding limiting plate.
[0015] Preferably, the limiting post includes a post body and an abutment plate. The abutment plate is disposed on the post body, and the spring is sleeved on the post body with one end abutting against the abutment plate and the other end abutting against the mounting shell, so that the post body extends out of the mounting shell and the abutment plate abuts against the mounting shell.
[0016] By adopting the above technical solution, and by setting up a column and abutment plate, the installation between the limiting column and the spring is facilitated, and the column limits the spring to avoid excessive bending of the spring, thereby improving the service life of the spring.
[0017] Preferably, the abutment plate is threadedly connected to the column.
[0018] By adopting the above technical solution, the abutment plate is threadedly connected to the column to facilitate adjustment of the position of the abutment plate, thereby adjusting the length of the column extending out of the mounting shell to ensure that the column can be inserted into the limiting hole.
[0019] Preferably, the limiting post further includes a force-applying rod, which is disposed on the abutment plate. The mounting shell has a sliding groove along its own length direction, and the force-applying rod is slidably connected to the sliding groove and extends out of the sliding groove.
[0020] By adopting the above technical solution and setting a force-applying rod, it is easy for workers to apply force, thereby facilitating the insertion of the column into the mounting shell and making it easier to insert the column into the limiting hole.
[0021] Preferably, the mounting housing also has a groove that communicates with the sliding groove for the force-applying rod to be embedded.
[0022] By adopting the above technical solution, by setting a groove, the column is rotated by the force-applying rod, so that the force-applying rod is embedded in the groove, thereby limiting the movement of the column driven by the spring. This facilitates the insertion or disengagement between the column and the limiting hole.
[0023] Secondly, this application provides an industrial washing machine.
[0024] The industrial washing machine provided in this application adopts the following technical solution:
[0025] An industrial washing machine includes the switch structure described above.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1. In practical applications, the operator holds the fastening handle to rotate the door and the fastening handle. After rotating to the appropriate position, the latch engages with the locking block. Then, the fastening handle is rotated in the opposite direction. Because the latch is connected to the fastening handle, the latch is more stably locked to the locking block, which minimizes the possibility of the latch and the locking block loosening during the operation of the industrial washing machine. This restricts the rotation of the door and ensures the normal operation of the industrial washing machine.
[0028] 2. By setting mounting bolts and mounting nuts, a rotational connection between the latch and the fastening handle can be achieved. Furthermore, by rotating the mounting nuts, the damping between the latch and the fastening handle can be adjusted, allowing the latch to be more stably locked onto the locking block.
[0029] 3. By setting a limit plate, mounting shell, limit post, and spring, rotate the fastening handle to bring the limit plate close to the limit post. Then press the limit post, which compresses the spring. Continue to rotate the fastening handle so that the limit post is inserted into the limit hole under the drive of the spring, thereby restricting the rotation of the fastening handle and further restricting the loosening between the latch and the locking block, thus further ensuring the stability of the industrial washing machine.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0036] This application discloses a switch structure.
[0037] Example 1:
[0038] Reference Figure 1 The switch structure includes a body 1, a switch door 2, and a fastening assembly 3. The body 1 is placed horizontally on the ground. The body 1 is hollow and has an opening on one side. The switch door 2 is rotatably connected to one side of the opening of the body 1. By rotating the switch door 2, the opening of the body 1 can be opened or closed to realize the opening and closing of the industrial washing machine.
[0039] Reference Figure 1 and Figure 2The fastening assembly 3 includes a fastening handle 31, a latch 32, and a locking block 33. One end of the fastening handle 31 is rotatably connected to the side of the door 2 away from the body 1. The latch 32 is U-shaped and is rotatably connected to the rotating end of the fastening handle 31. The locking block 33 is fixedly connected to the side of the body 1 near the door 2, and the shape of the locking block 33 matches the shape of the latch 32, so that the latch 32 is engaged in the locking block 33.
[0040] In practical applications, operators hold and rotate the fastening handle 31, which in turn rotates the door 2. When the fastening handle 31 and the door 2 are rotated to the appropriate position, the latch 32 engages with the locking block 33. Then, rotating the fastening handle 31 in the opposite direction further secures the latch 32 to the locking block 33, preventing it from loosening during operation and thus limiting the rotation of the door 2, ensuring the normal operation of the industrial washing machine.
[0041] Reference Figure 2 and Figure 3 In some embodiments, the fastening assembly 3 further includes a mounting member 34. Specifically, the mounting member 34 includes a mounting bolt 341 and a mounting nut 342. The end of the fastening handle 31 is limited to one end of the opening of the latch 32. The lower end of the mounting bolt 341 passes through the latch 32 and the fastening handle 31 and is threadedly connected to the mounting nut 342, so that the upper end of the fastening handle 31 and the mounting nut 342 are both pressed against the latch 32, thereby realizing the rotational connection between the latch 32 and the fastening handle 31. At the same time, by rotating the mounting nut 342, the damping between the latch 32 and the fastening handle 31 is adjusted, so that the lower end of the mounting bolt 341 and the mounting nut 342 are pressed more tightly against the latch 32, making it more difficult to rotate the latch 32, thereby enabling the latch 32 to be more stably locked onto the locking block 33.
[0042] In some embodiments, the fastening assembly 3 further includes a limiting plate 35, a mounting shell 36, a limiting post 37, and a spring 38. The limiting plate 35 is mounted on the fastening handle 31 and has a limiting hole 351. The mounting shell 36 is rectangular and is fixedly connected to the side of the switch door 2 away from the body 1. The fastening handle 31 is rotatably connected to one end of the mounting shell 36 to achieve a rotatable connection between the fastening handle 31 and the switch door 2. The limiting post 37 is movably inserted through the mounting shell 36. One end of the spring 38 abuts against the limiting post 37, and the other end abuts against the mounting shell 36. Driven by the spring 38, the limiting post 37 extends out of the mounting shell 36 away from the fastening handle 31, and the limiting post 37 matches the limiting hole 351.
[0043] After the latch 32 is engaged with the locking block 33, the limiting plate 35 is rotated to one end of the limiting post 37 by rotating the fastening handle 31. Then, the limiting post 37 is pressed, and the limiting post 37 compresses the spring 38. Then, the fastening handle 31 is rotated again, so that the limiting post 37 is inserted into the limiting hole 351 under the drive of the spring 38, so as to restrict the rotation of the fastening handle 31 and further restrict the latch 32 from loosening with the locking block 33, thereby further ensuring the stability of the industrial washing machine.
[0044] In some embodiments, the fastening assembly 3 further includes a fastening bolt 39. The limiting plate 35 has a sliding hole 352 and a relief groove 353. The fastening handle 31 is slidably connected to the sliding hole 352, so that the limiting plate 35 can slide along the length direction of the fastening handle 31 to adjust the position of the limiting plate 35, ensuring that the limiting post 37 can be inserted into the limiting hole 351. At the same time, the relief groove 353 is connected to the sliding hole 352, and the fastening bolt 39 is threadedly connected to the relief groove 353 of the limiting plate 35. By rotating the fastening bolt 39, the width of the relief groove 353 is shortened, so that the limiting plate 35 is clamped to the fastening handle 31 to fix the sliding limiting plate 35.
[0045] The implementation principle of this embodiment is as follows: In practical application, the operator holds the fastening handle 31 to rotate it. Rotating the fastening handle 31 causes the door 2 to rotate. When the fastening handle 31 and the door 2 are rotated to the appropriate position, the latch 32 engages with the locking block 33. Then, rotating the fastening handle 31 in the opposite direction, because the latch 32 is rotatably connected to the fastening handle 31, makes the latch 32 more stably locked with the locking block 33, minimizing the possibility of loosening between the latch 32 and the locking block 33 during the operation of the industrial washing machine. This restricts the rotation of the door 2, thereby ensuring the normal operation of the industrial washing machine.
[0046] Example 2:
[0047] Reference Figure 4 This embodiment is identical to Embodiment 1 in all other aspects, except that the limiting post 37 includes a post body 371 and an abutment plate 372. The post body 371 is movably inserted through the mounting shell 36, and the abutment plate 372 is fixedly connected to the post body 371. The spring 38 is sleeved on the post body 371, with one end of the spring 38 elastically abutting against the abutment plate 372 and the other end abutting against the mounting shell 36, thereby driving the post body 371 to extend out of the mounting shell 36 and driving the abutment plate 372 to abut against the mounting shell 36. This facilitates the installation between the limiting post 37 and the spring 38, and also allows the post body 371 to limit the spring 38, minimizing the risk of excessive bending and damage to the spring 38, thus improving its service life.
[0048] In some embodiments, the abutment plate 372 is threaded to the column 371 to adjust the position of the abutment plate 372, thereby adjusting the length of the column 371 extending out of the mounting shell 36 to ensure that the column 371 can be inserted into the limiting hole 351.
[0049] In some embodiments, the limiting post 37 further includes a force-applying rod 373, which is vertically arranged and fixedly connected to the periphery of the abutment plate 372. A sliding groove 361 is formed on the upper side of the mounting shell 36 along its own length direction. The force-applying rod 373 is slidably connected in the sliding groove 361 and extends out of the sliding groove 361. By applying force to the force-applying rod 373, the limiting post 37 can be driven to compress the spring 38 without pressing the end of the post 371, thereby facilitating the insertion of the post 371 into the mounting shell 36 and thus facilitating the insertion of the post 371 into the limiting hole 351.
[0050] In some embodiments, the mounting housing 36 is further provided with a groove 362, which is connected to the sliding groove 361 for the force-applying rod 373 to be embedded. The force-applying rod 373 is used to rotate the column 371 so that the force-applying rod 373 is embedded in the groove 362, thereby limiting the movement of the column 371 driven by the spring 38. This facilitates the insertion or disengagement of the column 371 from the limiting hole 351.
[0051] This application also discloses an industrial washing machine.
[0052] The industrial washing machine includes the switching structure described in the above embodiments.
[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
