DETAILED DESCRIPTION

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0015] like Figure 1 As shown, a special latch for doors and windows of a culture medium production line includes a latch tongue mechanism 1 and a latch buckle mechanism 2. The latch tongue mechanism 1 is engaged with the latch buckle mechanism 2. The latch tongue mechanism 1 is provided with a latch tongue base 11 and a latch tongue 12. The latch tongue 12 is fixed to the latch tongue base 11 with bolts. The latch tongue 12 is provided with a locking tongue with large ends and a small middle. The latch buckle mechanism 2 includes a latch buckle base 21 and a latch part 22. The latch part 22 is symmetrically welded to the latch buckle base 21. It is worth mentioning that this The symmetry line is the center line of the tongue 12, and the buckle 22 is provided with an adjusting nut 220, a buckle 221, an adjusting spring 222 and an anti-fouling pad 223. The adjusting spring 222 is sleeved on the buckle 221, and the buckle 221 is located in the active cavity 224 of the buckle 22 and one end is against the anti-fouling pad 223. The anti-fouling pad 223 is located on the inner wall of the active cavity 224 of the buckle 22, and the adjusting nut 220 is located at the end of the active cavity 224 of the buckle 22.

[0016] Specifically, the movable cavity 224 is a stepped hole, on which a limiting cam 224A is provided, the anti-fouling pad 223 is fixed on the limiting cam 224A, a screw thread is provided on the larger section of the stepped movable cavity 224, and the adjusting nut 220 is fixed on the movable cavity 224 through the screw thread and contacts the adjusting spring 222. The buckle 221 is located on the smaller section of the movable cavity 224, and the limiting cam 224A is located on the smaller section of the movable cavity 224, and the smaller section of the movable cavity 224 is truncated. The buckle 221 is provided with a round head 221A and a limiting block 221B, half of the round head 221A protrudes out of the movable cavity 224, and the other half contacts the anti-fouling pad 223, and the limiting block 221B cooperates with the limiting cam 224A. The anti-fouling pad 223 is a plastic with an elastic trapezoidal ring.

[0017] Detailed description of the working principle:

[0018] The buckle 22 is symmetrically welded on the buckle base 21, and the middle is just right for the tongue 12 to be inserted, because the buckle 221 can clamp the tongue 12 to prevent it from falling off due to the effect of the adjustment spring 222. The elastic anti-fouling pad 223 always touches the round head 221A to prevent pollutants from entering or breeding bacteria.
