Description

Technical Field

[0001] The utility model relates to the technical field of containers, and more specifically, to a high-airtightness folding container door. Background Art

[0002] Side-opening door containers are highly customizable. They can be customized in specific sizes and positions according to the cargo conditions to facilitate loading and unloading of cargo. Side-opening door containers are divided into full side-opening and partial side-opening, and the locking rod can be designed to extend beyond the corner or not extend beyond the corner.

[0003] For example, application number CN201520661779.1 discloses a side-opening container, including a container body and a door. The container body is provided with four supporting columns at the four corners, and corner pieces are provided on the supporting columns. Top longitudinal beams and bottom longitudinal beams are connected between the supporting columns. Box boards are respectively mounted on the top longitudinal beams and the bottom longitudinal beams. The door is provided at the rear end of the container body, and a pair of folding doors are provided on one side of the container body. The container has a reasonable structural design, is safe to use, has high material loading and unloading efficiency, meets the needs of various material loading and unloading, and has no impact on the container body.

If there are obstacles around, the door cannot be opened smoothly, and the structural design is extremely unreasonable. The overall sealing type of the container door is relatively poor, and the structural form of the profile and rubber strip is single. Utility Model Content

DETAILED DESCRIPTION

[0039] Example:

[0040] The following is combined with Figure 1-7 The utility model is described in further detail.

[0041] The high airtightness folding container door is mainly composed of two groups of symmetrical folding doors arranged on the box body 20, and the folding door on the right side is taken as an example. The side folding door includes a revolving door panel 10, a hinged door panel and a rubber strip 40. One end of the revolving door panel 10 is provided with a reinforcing rib connected by bolts, and is hinged to the outer side of the box body 20 through the reinforcing rib, so that the revolving door panel 10 rotates outward relative to the box body 20, that is, rotates outward counterclockwise. The other end of the revolving door panel 10 is provided with a profile on the inner side, and the folding door panel 30 is also provided with a profile correspondingly. An insulation board 90 is added between the profile and the plate. The revolving door panel 10 and the folding door panel 30 are hinged by two profiles, so that the two form an inward rotation structure, that is, the rotation of the two requires an inward force to be applied. The hinges of the two adjacent folding door panels 30 and the revolving door panel 10 and the box body 20 are all provided with corresponding grooves and plugged with rubber strips 40. The specific structure is not the focus of this application, and it is part of the prior art, so it will not be repeated.

[0042] The revolving door panel 10 is connected to the box body 20 via a row of hinge plates 11 , and the revolving door panel 10 is connected to the folding door panel 30 via hinges 12 .

[0043] After the hinged ends of the revolving door panel 10 and the folding door panel 30 are attached, three types of embedding grooves are formed, and three types of rubber strips 40 are embedded accordingly. The innermost first embedding groove 50 is two grooves that are separately arranged at the ends of their respective panels and have openings facing each other. The first embedding groove 50 is an outward-expanding structure, and a positioning alignment protrusion 51 is provided at the center end of the groove bottom. Embedded in the first embedding groove 50 are the first rubber strip 41 and the second rubber strip 42. The two rubber strips 40 belong to the same type of rubber strips 40, both of which have an outward-expanding tail structure and a rotating offset arc strip at the head end. The difference is that the offset arc strip of the first rubber strip 41 is counterclockwise, and the offset arc strip of the second rubber strip 42 is clockwise. After the tail end of the first rubber strip 41 is squeezed and inserted into the first embedding groove 50 of the folding door panel 30, it automatically recovers, and the offset arc strip extends out and squeezes into the first embedding groove 50 of the revolving door panel 10. The tail end of the second rubber strip 42 is squeezed and inserted into the first embedding groove 50 of the rotating door panel 10. The offset arc strips of the two rubber strips 40 are both deflected outwards.

[0044] The second embedding groove 60 in the middle position is formed by the groove bodies of the folding door panels 30 and the rotating door panels 10 on both sides being butted and spliced. The folding door panels 30 at this position are provided with an inner concave structure, and the rotating door panels 10 are provided with an outer convex structure. The inner side of the inner concave structure close to the box body 20 is an arc segment, and the outer side is a rectangular open inner groove. The outer convex structure close to the inner side of the box body 20 is also an arc segment, and the outer side is an irregular rectangular convex. After the two are butted and spliced, a second embedding groove 60 is formed, which is a semicircular arc segment on the inner side of the box body 20 and a rectangular segment on the outer side. The head end of the third rubber strip 43 embedded in the second embedding groove 60 is an arc structure with a hollow cavity, and the tail end is a rectangular structure with a notch on the left side.

[0045] The outermost third embedding groove 70 is formed by the groove bodies of the folding door panel 30 and the rotating door panel 10 being butted and joined up and down. An embedding groove 71 is provided on the outer end surface of the outer convex structure, opening outward. The structure of the embedding groove 71 is similar to that of the first embedding groove 50, one is horizontally arranged and the other is vertically arranged. The fourth rubber strip 44 embedded in the third embedding groove 70 has a sawtooth structure with a hollow cavity at the tail end and an outward expansion structure at the head end.

[0046] The rubber strip 40 with a hollow cavity cooperates with the embedded groove to improve the sealing between the folding door panel 30 and the revolving door panel 10. The revolving door panel 10 and the folding door panel 30 are structurally reinforced by the Z-shaped template 80 and bolts. All bolts are installed in the form of concave bolt grooves, which does not affect the smoothness of the panel surface. Reinforcing ribs are added between the revolving door panel 10 and the box body 20 to form a cavity and fill with rubber strips 40 to enhance structural strength and sealing. Rubber strips 40 are also filled between adjacent folding door panels 30. The overall folding space occupied by the folding door becomes smaller and is less affected by obstacles.

[0047] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
