Embodiment 1

[0018] Such as figure 1 , figure 2 As shown, the sliding door includes a right sliding door leaf 1 and a left sliding door leaf 2 that cooperate with each other to slide. After the right sliding door leaf 1 and the left sliding door leaf 2 are closed, there is an overlapping surface. On the overlapping surface corresponding to the left sliding door leaf 2, there is The left sliding door groove 5 is installed with a sealing strip 7 sliding along the depth direction of the left sliding door groove 5 in the left sliding door groove 5. The cross section of the sealing strip 7 is a semi-circular structure, and at the two ends of the semi-circular ring Limiting blocks 8 are all extended outwards, and the corresponding limiting block 8 is provided with a stopper to prevent the sealing strip 7 from sliding out of the left sliding door groove 5 at the notch of the left sliding door groove 5, corresponding to the semicircle of the sealing strip 7. The outer surface of the ring is prov...

Embodiment 2

[0026] On the basis of the first embodiment, the sealing assembly 3 is changed to an elastic rubber block; the maximum depth of cooperation between the sealing strip 7 and the groove 4 of the right sliding door is 4 mm.

[0027] Others are the same as embodiment one.

Embodiment 3

[0029] A change is made on the basis of Embodiment 1, and the maximum depth of cooperation between the sealing strip 7 and the groove 4 of the right sliding door is changed to 5mm.

[0030] Others are the same as embodiment one.

Abstract

The invention relates to a sliding door, and belongs to the technical field of sliding doors. The sliding door comprises a right sliding door leaf and a left sliding door leaf which slide in a matching mode with each other, an overlapping surface exists after the right sliding door leaf and the left sliding door leaf are closed, a left sliding door groove is formed in the overlapping surface corresponding to the left sliding door leaf, a sealing bar which slides in the depth direction of the left sliding door groove is installed in the left sliding door groove, the cross section of the sealingbar is of a semi circular ring structure, limiting blocks which extend outwards are arranged at two ends of the semi circular ring, baffle bars for preventing the sealing bar from sliding out of theleft sliding door groove are arranged on the limiting blocks at groove entrances of the left sliding door groove, a right sliding door groove is formed in the right sliding door leaf corresponding tothe outer surface of the semi circular ring of the sealing bar, a sealing assembly is arranged in the right sliding door groove, and the sealing assembly is matched with the outer surface of the semicircular ring of the sealing bar in a sealing mode. According to the sliding door, sealing is conducted by adopting an arc-shaped surface matching principle of the sealing bar and the sealing assembly, and relative sealing area is enlarged in the shortest sealing area.

Description

technical field [0001] The invention relates to a sliding door and belongs to the technical field of sliding doors. Background technique [0002] Last year, the applicant designed several sets of door installation structures for refrigerated trucks, but none of them were ideal. The structure was complicated and the production cost was relatively high. It is cost-effective, and now there are more and more small refrigerated vehicles. [0003] For this reason, the applicant has also designed a kind of downturn door type refrigerated carriage this year. Its structure mainly includes the carriage, and the right side of the carriage is a door opening. The sliding door and the lower flap door are composed of the upper sliding door, which is located on the left side of the lower flap door and is close to it. The corresponding upper sliding door is provided with slide rails on the front and rear sides of the carriage for the upper sliding door to slide freely up and down. The guid...
