Abstract
The utility model relates to a door of a fridge, more specifically relating to an ultra-low temp double-sealed door. The utility model is provided with an outer face plate and an inner face plate between which a heat-insulating layer is arranged. The outer face plate is provided with a handle, and the periphery of the inner face plate is provided with a seal strip. The utility model is characterized in that the inner side of the seal strip is provided with an intensified seal strip. The utility model has the advantages of simple structure, good sealed effect, etc. A gap is arranged between the seal strip and the intensified seal strip, so the thermal insulating effect can be further improved by utilizing the characteristic of air thermal insulating. The utility model can be extensively used in ultra-low temp fridge or ultra-low temp thermal insulating cabinet.
Description
Technical field
The utility model relates to the door of refrigerator, and specifically a kind of ultralow temperature double density is sealed up a door.
Background technology
As everyone knows, refrigerator or ice box all are provided with door, door of refrigerator also must have good sealing property except that having insulation effect, it generally is provided with outer panels, wainscot, be provided with insulation layer between outer panels and the wainscot, one side is provided with hinge, to be connected with refrigerator body, opposite side is provided with handle, so that open the door or close the door, in order to strengthen its sealing, around the wainscot of door, be provided with one deck weather strip, weather strip is connected with wainscot, and the hermatic door heat insulation effect of this structure is poor, is not suitable for ultralow temperature refrigerator and ultralow temperature ice box and uses.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of ultralow temperature double density simple in structure, high insulating effect to seal up a door.
The utility model can reach by following measure:
A kind of ultralow temperature double density is sealed up a door, and is provided with outer panels, wainscot, is provided with insulation layer between outer panels and the wainscot, and outer panels is provided with handle, and the wainscot periphery is provided with weather strip, it is characterized in that the weather strip inboard is provided with the enhanced leaktightness bar on the wainscot.
In order further to increase heat insulation effect of the present utility model, be provided with the gap between weather strip and the enhanced leaktightness bar, weather strip is connected by connection strap with the enhanced leaktightness bar.
The utility model is owing to adopt said structure, have advantages such as simple in structure, good sealing effect, be provided with the gap between weather strip and the enhanced leaktightness bar, the characteristics of air thermal insulation have been made full use of, its heat insulation effect is further enhanced, can be widely used in the insulation of ultralow temperature refrigerator or ultralow temperature and cashier's office in a shop uses.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, also is the structural representation of a kind of embodiment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings: a kind of ultralow temperature double density is sealed up a door, be provided with outer panels, wainscot 1, be provided with insulation layer between outer panels and the wainscot 1, can be provided with handle on the outer panels, the wainscot periphery is provided with weather strip 2, outer panels, wainscot 1, insulation layer, the structure and the interconnected relationship of handle and weather strip 2 are same as the prior art, this does not give unnecessary details, feature of the present utility model is that weather strip 2 inboards are provided with enhanced leaktightness bar 3 on the wainscot 1, in order further to increase heat insulation effect of the present utility model, be provided with the gap between weather strip 2 and the enhanced leaktightness bar 3, weather strip is connected by connection strap 4 with the enhanced leaktightness bar, enhanced leaktightness bar 3 can adopt the weather strip the same with weather strip 2, also can be processed into the special seal bar of weather strip 2 and enhanced leaktightness bar 3 disjunctors, with the utlity model has simple in structure, advantages such as good sealing effect, be provided with the gap between weather strip and the enhanced leaktightness bar, the characteristics of air thermal insulation have been made full use of, its heat insulation effect is further enhanced, can be widely used in the insulation of ultralow temperature refrigerator or ultralow temperature and cashier's office in a shop uses.
