Description
Technical field
The utility model relates to a kind of preventing water leakage commercial refrigerator downpipe structure.Be mainly used in commercial refrigerator.
Background technology
As shown in Figure 1, in commercial refrigerator, modal is that downpipe 4 is first overlapped after a rubber seal 2, inserts in the counterbore of interior plate 1, then screws with nut outside.The maximum disadvantage of this downpipe structure is easily to leak, and for deep freezer, after leaking, water can freeze in foaming layer, so just destroy hard polyurethane foam layer structure, after refrigerator defrost is frozen again, destroy further foaming layer, finally caused foaming layer all to damage, lost the function of insulation.
Utility model content
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of simple in structure, be skillfully constructed, preventing water leakage commercial refrigerator downpipe structure easy for installation, thoroughly to solve the drainage of downpipe in current refrigerator.
The technical scheme that the utility model adopts is: a kind of preventing water leakage commercial refrigerator downpipe structure, comprise interior plate, rubber seal and downpipe, and described interior plate is shaped with base plate counterbore at installation downpipe place, it is characterized in that:
Described base plate counterbore is shaped with circle flange straight down in its aperture;
Described downpipe is divided into three parts, top is the downpipe one-level counterbore of internal diameter and flange external diameter adaptation, middle part is the downpipe secondary counterbore that is slightly less than flange internal diameter with internal thread and internal thread diameter, and bottom is smooth through hole, and described flange is seated in described downpipe one-level counterbore;
Equipped downpipe lid after lining is established rubber seal on base plate counterbore, this downpipe lid outward appearance is bolt shape, the circular cover on top is pushed down rubber seal, and bottom is shaped with the external screw thread matching with internal thread on described downpipe, opens an inner hexagonal hole along downpipe lid axis.
Described circular cover has the radial draining shallow slot of some through external screw thread roots at its back side.
Described flange overcoat has rubber seal.
The height of described flange is 2～4 millimeters, is less than the degree of depth of one-level counterbore.
The beneficial effects of the utility model are: the utility model has carried out local improvement to original downpipe structure, retaining former basic structure, seldom taking up space, have under the front dike that increases cost, have solved dexterously refrigerator seepy question.Simple and reasonable, easy for installation after improvement, experimental results show that and can reach good waterproof effect.As slightly loosening between downpipe and water falling hole, water still can enter downpipe by draining shallow slot, can not outflow and affect foaming layer.

Detailed description of the invention
Embodiment 1: the present embodiment is a kind of preventing water leakage commercial refrigerator downpipe structure, this structure comprises that interior plate 1(is as shown in Figure 2), rubber seal 2 and downpipe 4(as shown in Figure 3), wherein on interior plate 1, be shaped with the base plate counterbore 1-1 that downpipe 4 is installed, this counterbore can be held back polywater, and anti-sealing leaks outside.Be shaped with circle flange 1-2 straight down at the aperture place of base plate counterbore 1-1, described flange 1-2 coordinates with downpipe 4.The height of this routine flange 1-2 is 3mm, should be less than the one-level counterbore degree of depth.
Downpipe 4 is divided into three parts, and it is smooth that top is shaped with one-level counterbore 4-1(internal diameter), the internal diameter of this one-level counterbore 4-1 and flange 1-2 adaptation, and flange 1-2 inserts in downpipe one-level counterbore 4-1.Downpipe 4 middle parts are to be with female secondary counterbore 4-2, and the internal thread diameter of this secondary counterbore 4-2 is slightly less than flange 1-2, to ensure follow-up completing and the assembling of other parts.Downpipe 4 bottoms are smooth through hole 4-3, and this through hole 4-3 is used for draining.
As shown in Figure 4, the similar bolt of downpipe lid 3 profile, its top is circular cover 3-1, on lower cylindrical body, be shaped with external screw thread 3-2, be used for matching with the internal thread on downpipe secondary counterbore 4-2, open an inner hexagonal hole 3-3 along downpipe lid 3 axis on the one hand for draining, can use on the other hand inner hexagon spanner turn downpipe lid.Described circular cover 3-1 is used for compressing rubber seal 2.
The installation method of the present embodiment is as follows:
As shown in Figure 5, first downpipe 4 is set in to the flange 1-2 outside of interior plate 1, then has the downpipe lid 3 of rubber seal 2 to pack in downpipe 4 in cover, screw downpipe lid 3 and downpipe 4 with inner hexagon spanner afterwards.
This routine rubber seal 2 is enclosed within on the external screw thread 3-2 of downpipe lid 3, is sandwiched between base plate counterbore 1-1 and circular cover 3-1.
Embodiment 2: the structure of the present embodiment and embodiment 1 is basic identical, unique different place is: have the draining shallow slot 3-4(of some through external screw thread 3-2 roots at the back side of downpipe lid 3 circular cover 3-1 as shown in Figure 6), this draining shallow slot 3-4 is radial, and its effect is a small amount of residual water between emptying downpipe lid 3 and base plate counterbore 1-1.
The installation method of the present embodiment is as follows:
As shown in Figure 7, outside the flange 1-2 of interior plate 1, after sheathed rubber seal 2, downpipe 4 is set in outside flange 1-2, afterwards the downpipe lid 3 that has draining shallow slot 3-4 is packed in downpipe 4, screw downpipe lid 3 and downpipe 4 with inner hexagon spanner.
This routine rubber seal 2 is enclosed within flange 1-2 outside, is sandwiched between base plate counterbore 1-1 and downpipe 4 tops.
Each embodiment that the claimed scope of the utility model is not limited to introduce herein, all various forms of conversion of doing based on the utility model claim and description and replacement, all belongs to the scope that the utility model patent contains.
