[0002] With the continuous improvement of people's living standards, various household appliances are becoming increasingly popular in people's daily lives. Mechanical knobs for manual operation are often provided on household appliances. The mechanical knob generally includes a knob cover and a knob shaft extending into the electrical appliance housing. The inner surface of the knob cover has a tubular knob hole, and the knob cover is installed on the knob shaft by sleeving the outer end of the knob shaft through the knob hole. In order to prevent the knob from disengaging from the knob shaft during use, an interference fit is adopted between the knob hole and the knob shaft.

[0003] The patent specification with the publication number of CN202121205874.2 discloses a fastening knob, which "comprises an outer sleeve and an inner liner. The surface of the outer sleeve is provided with anti-slip grooves, and the inner side of the outer sleeve is provided with an inner wall, and internal threads are provided on the surface of the inner wall. An installation cavity is provided inside the inner liner, and an upper end portion is provided on the outer side of the installation cavity, and a claw is provided at the upper end of the upper end portion. An arc-shaped end face is provided on the outer side of the claw, and a friction surface is provided on the inner side of the claw. A vertical section is provided at the lower end of the claw, and external threads are provided on the surface of the vertical section, and a positioning hole is provided at the lower end of the external threads. This fastening knob has a reasonable structure, is simple in structure, convenient to manufacture and install, convenient to adjust the tightness, firm in fastening and not easy to be damaged".

[0004] However, it is found that the above-mentioned fastening knob has the following problems in the implementation of related technologies: Since the knob is often exposed during use, it is easily impacted or misoperated externally and is accidentally driven to rotate, resulting in the sudden opening or closing of the device, and thus triggering safety accidents. In view of this, an anti-slip fixed knob based on a new process is provided to overcome the above defects. Content of the Utility Model

[0023] As a further implementation of the above technical solution: The locking assembly 7 includes a plurality of chutes 71, a plurality of sliding plates 72, a plurality of return springs 73 and a plurality of elastic pieces 74. The plurality of chutes 71 are equidistantly opened on the surface of the card hole 6. The inner walls of the plurality of chutes 71 are all slidably connected with sliding plates 72. On one side of the inner walls of the plurality of chutes 71, two return springs 73 are fixedly provided respectively. One ends of the plurality of return springs 73 are fixedly connected with the plurality of sliding plates 72 respectively. On one side of the plurality of sliding plates 72, elastic pieces 74 are fixedly provided respectively;

[0024] A groove 9 is opened on the surface of the card shaft 5. A plurality of anti-slip strips 10 arranged at equal intervals are fixedly provided on the inner wall of the groove 9. The plurality of anti-slip strips 10 and the plurality of elastic pieces 74 are both magnetic attraction blocks of opposite-sex magnetic poles. By the tapered end of the card shaft 5 pressing the plurality of elastic pieces 74, the plurality of elastic pieces 74 are stressed to make the plurality of return springs 73 contract. At the same time, the plurality of sliding plates 72 respectively slide into the inner walls of the plurality of chutes 71. When the groove 9 moves to the same horizontal plane as the plurality of chutes 71, the plurality of return springs 73 reset to make the plurality of elastic pieces 74 respectively move into the plurality of grooves 9. At this time, rotate the torsion part 1 to threadedly fix the connecting disk 2 and the card shaft 5 through the screw block 12. Then, through the mutual attraction of the opposite-sex magnetic poles of the plurality of anti-slip strips 10 and the plurality of elastic pieces 74, the stability of the fixed card shaft 5 is improved, and it is not easy to cause the knob to loosen due to rotation.

[0025] As a further implementation of the above technical solution: The sealing assembly 8 includes a first sealing ring 81, a second sealing ring 82 and a sealing strip 83. The first sealing ring 81 is fixedly provided at the top end of the chuck 4. The second sealing ring 82 is fixedly provided on the surface of the chuck 4. The sealing strip 83 is fixedly provided in the middle of the top end of the chuck 4;

[0026] A waterproof rubber strip 11 is fixedly provided between the first sealing ring 81 and the sealing strip 83. The bottom end of the hemisphere 3 is rotatably connected between the first sealing ring 81 and the second sealing ring 82. Through the first sealing ring 81 and the second sealing ring 82, the sealing performance between the hemisphere 3 and the chuck 4 can be effectively improved. At the same time, the sealing strip 83 can seal the gap between the card shaft 5 and the card hole 6, thereby effectively improving the sealing effect of the knob, and further preventing dust and water vapor from entering the knob to cause it to loosen.

[0027] As a further implementation of the above technical solution: A screw block 12 is fixedly provided at the top end of the card shaft 5. The screw block 12 is threadedly connected with the connecting disk 2.

[0028] As a further implementation of the above technical solution: Anti-slip lines 13 are fixedly provided on the surface of the torsion part 1.

[0029] Working principle: First, insert the spindle 5 of the chuck 4 into the inside of the card hole 6. During the insertion process of the spindle 5 with a conical top, several elastic pieces 74 are stressed, causing several return springs 73 to contract. At the same time, several sliding plates 72 slide into the inner walls of several sliding grooves 71 respectively. When the groove 9 moves to the same horizontal plane as several sliding grooves 71, several return springs 73 reset, causing several elastic pieces 74 to move into several grooves 9 respectively. At this time, rotate the torsion part 1 to thread-fix the connecting plate 2 and the spindle 5 through the screw block 12. Then, through the mutual attraction of several anti-slip strips 10 and the opposite magnetic poles of several elastic pieces 74, the stability of the fixed spindle 5 is improved, and it is not easy to cause the knob to loosen due to rotation. Moreover, during the application of this knob, the hemispherical body 3 rotates between the first sealing ring 81 and the second sealing ring 82. The first sealing ring 81 and the second sealing ring 82 can effectively improve the sealing performance between the hemispherical body 3 and the chuck 4. At the same time, the sealing strip 83 can seal the gap between the spindle 5 and the card hole 6. Then, the waterproof rubber strip 11 is used to waterproof the connection part of this knob, thereby effectively improving the sealing effect of this knob, and further preventing dust and water vapor from entering the inside of this knob and causing it to loosen.
