Abstract
The utility model provides a no-rivet door structure for a refrigerated container, which comprises a door frame, the inner edge of a frame body of the door frame is provided with a groove section, an outer door plate spliced into the groove section of the door frame, an insulation foam layer positioned at the inner side of the outer door plate. A pair of lug bosses is formed and rises up in the opposite direction on the opposite inner walls of the groove section. The pair of lug bosses has a difference in height and a level interval between the pair of lug bosses is no more than the thickness of the outer door plate, thus clamping the outer door plate to lead the door plate and door frame to be sealed. By adopting the no-rivet door structure of the utility model, when the outer door plate is inserted into the door frame, the lug bosses impose certain pretightening force to the door plate, thus achieving better sealing performance and preventing the plate surface from being polluted caused by the leaking of foaming liquid during the frothing course.

In above-mentioned no rivet type door, this concave part can be formed by framework inner edge one two extension arms upwardly extending, that keep at a certain distance away of this doorframe certainly.
In above-mentioned no rivet type door, described a pair of lug boss can be formed at the free end of described two extension arms respectively.
In above-mentioned no rivet type door, the length that is positioned at the extension arm of this external door panel inboard in described two extension arms can be greater than the length of the extension arm that is positioned at this external door panel outside.
In above-mentioned no rivet type door, being positioned at the end face of the lug boss on the extension arm of this external door panel inboard and angle that this external door panel forms can be greater than 90 degree.
In above-mentioned no rivet type door, the contact surface of described at least a pair of lug boss one of them and this external door panel can be formed with anti-skidding line.
In above-mentioned no rivet type door, the inside face of this concave part can be coated with adhesives.
In above-mentioned no rivet type door, the contact jaw of this external door panel and this groove inner bottom part can be provided with Continuous pressing device for stereo-pattern.
Compared with prior art, the no rivet type door of refrigerated container of the present utility model has following beneficial effect: by be formed with a pair of lug boss of projection in opposite directions on the opposed inner walls of this concave part, has diff-H between the described a pair of lug boss, and the level interval L between the described a pair of lug boss is not more than the thickness D of external door panel, clamping external door panel more securely, when external door panel is inserted doorframe, certain predetermincd tension is arranged, thereby reach the fastening effect of better sealing; In addition, the angle that the end face of lug boss and external door panel form can prevent to cause in foaming process foaming liquid to leak, pollute the problem of plate face greater than 90 degree better.

The specific embodiment
Below in conjunction with embodiment shown in the drawings the technical solution of the utility model is done further detailed description.
Fig. 2 a and Fig. 2 b are respectively the partial schematic diagram of no rivet type door of refrigerated container of the present utility model and the partial enlarged drawing of B portion.Shown in Fig. 2 a and Fig. 2 b, this no rivet type door comprises: doorframe 5, be plugged in external door panel 3 in the doorframe 5, be positioned at the heat insulation foaming layer 4 of external door panel 3 inboards, be installed in locking bar 1 and other respective accessory Door sealing adhesive tapes, interior lining panel and the inner reinforced rib etc. in external door panel 3 outsides by bolt 2.
In no rivet type door of the present utility model, also be formed with a pair of lug boss 8 and 9 of projection in opposite directions on the opposed inner walls of this concave part 7, have diff-H between lug boss 8 and the lug boss 9, and the level interval between lug boss 8 and the lug boss 9 is not more than the thickness of external door panel.Specifically see also Fig. 2 b and Fig. 3 a, concave part 7 two extension arms 71 and 72 upwardly extending by the framework inner edge one of doorframe 5, that keep at a certain distance away form, lug boss 8 and lug boss 9 are formed at the free end of two extension arms 71 and 72 respectively, and make simultaneously level interval L between lug boss 8 and the lug boss 9 (a) be not more than the thickness D (referring to Fig. 2 b) of external door panel 3 referring to Fig. 3, with this external door panel of clamping and make this door-plate and this doorframe between seal.When the concave part 7 on the external door panel 3 insertion doorframes 5, apply certain predetermincd tension by lug boss 8 and 9 to door-plate 3, thus but enhanced leaktightness effect.
Preferably, two extension arms 71 can be different with 72 length, the length of extension arm 71 that for example is positioned at external door panel 3 inboards is greater than the length of the extension arm 72 that is positioned at external door panel 3 outsides, thereby makes that to form certain height between extension arm 71 and 72 free- ended lug bosses 8 and 9 poor.Certainly, lug boss 8 and 9 height and position are not limited to the free end of extension arm 71 and 72, but can be positioned at any height and position on extension arm 71 and 72.
Moreover by Fig. 2 b as seen, the end face and the external door panel 3 that are positioned at the lug boss 8 on the extension arm 71 of external door panel 3 inboards are formed with certain angle [alpha], and this angle [alpha] is greater than 90 degree, to prevent foaming liquid leakage pollution external door panel 3 better.
Further, by Fig. 3 b as seen, lug boss 8 is formed with anti-skidding line 10 with the contact surface of external door panel 3, to increase the friction force between external door panel 3 and the lug boss 8, makes doorframe clamping external door panel more firmly 3.Simultaneously, lug boss 8 also can be formed with anti-skidding line with the contact surface of external door panel 3.
In addition, for the leakproofness that makes external door panel 3 and doorframe 5 better, more firm being connected, can also be coated with adhesives (as: butyl rubber) at the inside face of groove 7, perhaps can also be provided with Continuous pressing device for stereo-pattern at the contact jaw of external door panel 3 and groove 7 inner bottom parts.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any personnel that are familiar with this technology may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations;, all still belong in the scope that the utility model asks for protection any simple modification, equivalent variations and modification that above embodiment did according to technical conceive of the present utility model.
