DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1 to 8 As shown, a solenoid valve comprises a solenoid valve body 1, a wiring port 11 is provided on the solenoid valve body 1, a wire 2 is inserted into the wiring port 11, a mounting portion 12 is provided on the wiring port 11, an anti-loosening mechanism 3 is provided on the wiring port 11, the anti-loosening mechanism 3 comprises a connection box 31, the connection box 31 is connected to the mounting portion 12, a first fixing sleeve 32 and a second fixing sleeve 33 are provided in the connection box 31, the first fixing sleeve 32 and the second fixing sleeve 33 are both arranged in contact with the wiring port 11, a through hole is provided on the connection box 31 for the power supply line 2 to pass through; a fixing component 4 capable of driving the first fixing sleeve 32 and the second fixing sleeve 33 to move is provided on the top of the connection box 31.

[0026] When it is necessary to fix the wire 2, first install the connection box 31 on the wiring port 11 through the installation part 12. After the connection box 31 is installed, insert the wire 2 into the wiring port 11 from the through hole of the connection box 31. When the wire 2 is connected to the wiring port 11, the user drives the first fixing sleeve 32 and the second fixing sleeve 33 to move through the fixing component 4, so that the first fixing sleeve 32 and the second fixing sleeve 33 clamp the wire 2 to ensure that the wire 2 will not fall off or loosen during long-term use. Through the arrangement of the first fixing sleeve 32, the second fixing sleeve 33 and the fixing component 4, it is ensured that the wire 2 can be fixed in the wiring port 11, so that the wire 2 will not fall off or loosen due to long-term use or shaking of the solenoid valve, thereby improving the stability of the work.

[0027] Reference Figure 3 and Figure 4As shown, the mounting portion 12 includes a mounting ring 121 , which is sleeved on the wiring port 11 , and a mounting groove 122 is provided in the mounting ring 121 . A mounting block 311 matching the mounting groove 122 is provided at one end of the connection box 31 .

[0028] When the connection box 31 needs to be installed on the wiring port 11 , the user holds the connection box 31 , aligns the mounting block 311 with the mounting groove 122 , and inserts the mounting block 311 into the mounting groove 122 , so that the connection box 31 is fixed on the wiring port 11 .

[0029] Reference Figure 5 As shown, a moving rod 321 is provided at one end of the first fixing sleeve 32 and the second fixing sleeve 33 away from the electric wire 2 , and a through hole for the moving rod 321 to pass through is provided on the connection box 31 .

[0030] By setting the moving rod 321, the first fixing sleeve 32 and the second fixing sleeve 33 are more stable when being driven by the fixing assembly 4 to move, ensuring that the first fixing sleeve 32 and the second fixing sleeve 33 will not deviate when moving, thereby improving the working stability.

[0031] Reference Figure 5 and Figure 6 As shown, the fixing assembly 4 includes a rotating rod 41, which is arranged on the connecting box 31. The connecting box 31 is provided with a through hole for the rotating rod 41 to pass through. The rotating rod 41 extends to the inside of the connecting box 31, and one end of the connecting box 31 is provided with a protective portion 34. The end of the connecting box 31 away from the protective portion 34 is provided with a gear 42. The upper and lower ends of the gear 42 are respectively provided with a first rack 43 and a second rack 44 meshing therewith, and the ends of the first rack 43 and the second rack 44 away from the gear 42 are both provided with a connecting frame 45, and the connecting frames 45 are respectively connected to the corresponding moving rods 321.

[0032] When it is necessary to fix the wire 2, the user twists the rotating rod 41, and the rotating rod 41 drives the gear 42 to rotate. Through the engagement of the first rack 43, the second rack 44 and the gear 42, the first rack 43 and the second rack 44 begin to move with the rotation of the gear 42. The movement of the first rack 43 and the second rack 44 drives the connecting frame 45 to move, and the connecting frame 45 drives the moving rod 321 to move, so that the moving rod 321 can drive the first fixing sleeve 32 and the second fixing sleeve 33 to move, so that the wire 2 can be fixed by the first fixing sleeve 32 and the second fixing sleeve 33.

[0033] Reference Figure 6As shown, a limit rod 421 is provided at one end of the gear 42 away from the rotating rod 41, and the limit rod 421 is rotatably connected to the inside of the connecting box 31. A connecting rod 431 is provided at one end of the first rack 43 and the second rack 44 respectively. A slider 432 is provided at the connecting rod 431 away from the gear 42, and a slide rail 433 for the slider 432 to slide is provided inside the connecting box 31.

[0034] By setting the slide rail 433 and the slider 432, the first rack 43 and the second rack 44 can move more smoothly, and at the same time, the first rack 43 and the second rack 44 can be more stable during operation, so that the first fixing sleeve 32 and the second fixing sleeve 33 will not deviate during movement, thereby improving the working stability.

[0035] Reference Figure 7 and Figure 8 As shown, the protective part 34 includes a sleeve 341, which is arranged at one end of the rotating rod 41 away from the gear 42, and the sleeve 341 is fixedly connected to the rotating rod 41. A rotating shaft 342 is provided at the end of the sleeve 341 away from the rotating rod 41, and the rotating shaft 342 is plugged into the sleeve 341. A protrusion 3421 is provided on the rotating shaft 342, and a rotating groove 3411 that cooperates with the protrusion 3421 is provided in the sleeve 341.

[0036] When it is necessary to rotate the rotating rod 41, the user rotates the rotating shaft 342 to match the protrusion 3421 on the rotating shaft 342 with the rotating groove 3411 in the sleeve 341, and inserts the rotating shaft 342 and the protrusion 3421 into the sleeve 341. At this time, rotating the rotating shaft 342 drives the sleeve 341 to rotate, and the rotating rod 41 is driven to rotate through the rotation of the sleeve 341. The setting of the protrusion 3421 and the rotating groove 3411 ensures that the user will not accidentally touch the gear 42, and the gear 42 will not rotate, thereby improving the stability of the operation.

[0037] Reference Figure 8 As shown, a knob 3422 is provided at one end of the rotating shaft 342 away from the sleeve 341 .

[0038] The setting of the knob 3422 makes it easier for the user to drive the rotating shaft 342 to rotate, making the work more convenient.

[0039] Reference Figure 7 As shown, the first fixing sleeve 32 and the second fixing sleeve 33 are both provided with anti-slip grooves 322 .

[0040] By providing the anti-slip groove 322 , the first fixing sleeve 32 and the second fixing sleeve 33 can better fix the electric wire 2 , thereby improving the working stability.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
