Description

Technical Field

[0001] This utility model relates to the field of crankcase sealing technology for cleaning machines, specifically a waterproof sealing device for crankcases of cleaning machines. Background Technology

[0002] The crankcase is an important component inside a cleaning machine, especially in high-pressure cleaners. The crankcase works in conjunction with other components such as the pump to complete the cleaning work. The design and operating condition of the crankcase directly affect the overall performance and lifespan of the cleaning machine. Therefore, keeping the crankcase clean and in good condition is crucial to ensuring the normal operation of the cleaning machine.

[0003] In existing technologies, a sealing ring is installed at the crankcase output shaft position. Because the connection between the sealing ring and the output shaft will rub against each other for a long time, the sealing ring needs to be replaced frequently. However, the sealing ring needs to be disassembled with a variety of tools, which makes the operation inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a crankcase waterproof sealing device for a cleaning machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crankcase waterproof sealing device for a cleaning machine, comprising a crankcase, an mounting block fixedly connected to the crankcase, a limiting groove formed on the mounting block, a plurality of connecting rods arranged in an array slidably connected inside the limiting groove, a rotating ring fixedly connected to one end of the plurality of connecting rods, a plurality of toothed blocks arranged in an array on the inner ring of the rotating ring, a receiving groove formed at the center of the mounting block, a sealing ring slidably connected inside the receiving groove, a spring fixedly connected to the crankcase at a position corresponding to the receiving groove, an abutment ring fixedly connected to the spring, symmetrically arranged rotating rods rotatably connected to the mounting block, a blocking rod fixedly connected to each of the two rotating rods, and a driven gear fixedly connected to each of the two rotating rods.

[0006] Preferably, the limiting groove is annular in shape, and the receiving groove is annular in shape.

[0007] Preferably, the spring is located inside the receiving groove, the spring is in a compressed state, and the rotating ring has multiple leverage grooves arranged in an array.

[0008] Preferably, the abutment ring is slidably connected inside the receiving groove, and the abutment ring abuts against the opposite surface of the sealing ring.

[0009] Preferably, the driven gears are all meshed with the tooth blocks, and the blocking rod abuts against the sealing ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: when disassembling the sealing ring, no external tools are needed. Simply rotate the rotating ring, and the rotation of the rotating ring will cause all components to work together. At this time, the two blocking rods that block the sealing ring will rotate simultaneously. Then, the spring inside the receiving groove will slowly squeeze the sealing ring out of the receiving groove, thereby completing the disassembly of the sealing ring. This utility model does not require many external tools, which simplifies the steps for workers to disassemble the sealing ring and makes it more convenient. It is worth promoting and using.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: a crankcase waterproof sealing device for a cleaning machine, including a crankcase 1, an mounting block 2 fixedly connected to the crankcase 1, a limiting groove 3 opened on the mounting block 2, a plurality of connecting rods 4 arranged in an array slidably connected inside the limiting groove 3, a rotating ring 5 fixedly connected to one end of the plurality of connecting rods 4, a plurality of toothed blocks 6 arranged in an array on the inner ring of the rotating ring 5, a receiving groove 7 opened at the center position of the mounting block 2, a sealing ring 8 slidably connected inside the receiving groove 7, a spring 9 fixedly connected to the crankcase 1 at a position corresponding to the inside position of the receiving groove 7, an abutment ring 10 fixedly connected to the spring 9, symmetrically arranged rotating rods 11 rotatably connected to the mounting block 2, a blocking rod 12 fixedly connected to each of the two rotating rods 11, and a driven gear 13 fixedly connected to each of the two rotating rods 11.

[0018] The limiting groove 3 is ring-shaped, and the receiving groove 7 is also ring-shaped. The limiting groove 3 facilitates the rotation of the connecting rod 4. The spring 9 is located inside the receiving groove 7 and is in a compressed state. The rotating ring 5 has multiple leverage grooves 14 arranged in an array. The compressed state of the spring 9 facilitates the ejection of the sealing ring 8 from inside the receiving groove 7. The leverage grooves 14 facilitate the rotation of the rotating ring 5 by the operator. The abutting ring 10 is slidably connected inside the receiving groove 7 and abuts against the opposite surface of the sealing ring 8. The abutting ring 10 facilitates the pushing of the sealing ring 8. The driven gears 13 are all meshed with the toothed blocks 6. The blocking rod 12 abuts against the sealing ring 8, and the toothed blocks 6 facilitate the rotation of the driven gears 13.

[0019] Specifically, when using this utility model, the sealing ring 8 can provide a seal at the output shaft position on the crankcase 1, preventing water from entering the crankcase 1 through the output shaft position. When the sealing ring 8 needs to be disassembled, the rotating ring 5 can be rotated directly through the lever groove 14. The rotation of the rotating ring 5 will drive multiple connecting rods 4 to rotate together inside the limiting groove 3. The rotating ring 5 will drive multiple gear blocks 6 to rotate together. The gear blocks 6, following the rotation of the rotating ring 5, will drive the driven gear 13 to rotate. The rotation of the driven gear 13 will drive the rotating rod 11 to rotate. The rotation of both rods will cause the blocking rods 12 to rotate as well. The two blocking rods 12 will then rotate in opposite directions and will no longer abut against the outer wall of the sealing ring 8. At this point, the sealing ring 8 loses its abutment, and the force of the spring 9's compression will be released. The spring 9 will then drive the abutment ring 10 to push the sealing ring 8. As the sealing ring 8 is pushed and fits against the inner wall of the receiving groove 7, it will slowly move out of the receiving groove 7. The entire operation does not require many external tools, which simplifies the steps for workers to disassemble the sealing ring 8 and makes it more convenient. It is worth promoting and using.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
