The utility model provides an inner door sealing strip for a box body, and aims to solve the technical problem.
In order to achieve the purpose, the technical solution of the utility model is as follows:
the inner door sealing strip for the box body comprises a bottom edge and a lip edge, wherein the lip edge is connected with two ends of the bottom edge to form an annular structure, and a sliding material coating is arranged on the outer side of the lip edge; and extension parts are further arranged at two ends below the bottom edge.
Preferably, the lip edge is connected with two ends of the bottom edge at a right angle, and the middle part of the lip edge is upwards protruded.
Preferably, the slip coating is disposed at a middle portion of the lip.
Preferably, the slip coating is a thermoplastic elastomer.
Preferably, the extension part extends towards two sides, and the end part of the extension part is provided with an upward hook-shaped bulge.
Preferably, the bottom of the extension part is provided with a downward projection.
The utility model has the beneficial effects that:
1. according to the inner door seal, the sliding material coating is arranged on the lip edge, and under the condition that the door seal is frozen due to low temperature on a box body, the sliding material coating can reduce the friction force of the door seal, so that the box door is easier to open.
2. The lip edge is of an annular structure, so that a double-layer sealing effect is achieved, and the air tightness of a box door of the box body is better.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In addition, the technical solutions in the embodiments of the present invention may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, the inner door sealing strip for the box body comprises a bottom edge 1 and a lip edge 2, wherein the lip edge 2 is connected with two ends of the bottom edge 1 to form an annular structure, and a sliding material coating 3 is arranged on the outer side of the lip edge; and extension parts 4 are arranged at two ends below the bottom edge.
The sealing strip for the box body can be used on a container, a van vehicle and a cold storage door; the lip edge 2 of the inner door seal is provided with a sliding material coating 3, and the sliding material coating can reduce the friction force of the door seal under the condition that the door seal is frozen due to low temperature on the box body, so that the box door can be opened more easily. The lip edge 2 is of an annular structure, so that a double-layer sealing effect is achieved, and the air tightness of a box door of the box body is better.
Further, the lip edge 2 is connected with two ends of the bottom edge 1 in a right angle, and the middle part of the lip edge 2 protrudes upwards. Preferably, the sliding material coating 3 is provided at the middle portion of the lip. Preferably, the slip coating is a thermoplastic elastomer. The height of the lip can be adjusted according to the actual situation, and the sectional views are shown in fig. 1 to 3.
