According to the technical scheme, the commercial refrigerator downspout structure capable of preventing water leakage comprises an inner container base plate, a rubber sealing ring and a downspout, wherein a base plate counter bore is manufactured in the position, where the downspout is installed, of the inner container base plate. The commercial refrigerator downspout structure capable of preventing water leakage is characterized in that a circle of vertical downward turnup is manufactured on the opening of the bottom plate counter bore; a first stage counter bore with the inner diameter adapting to the outer diameter of the turnup is formed in the upper portion of the downspout, a second stage counter bore provided with internal threads is formed in the middle of the downspout, and the diameter of the internal threads is slightly smaller than the inner diameter of the turnup; a smooth through hole is formed in the lower portion of the downspout, and the turnup is located in the first stage counter bore of the downspout; after the bottom plate counter bore is provided with a rubber sealing ring in a lining mode, a downspout cover is assembled, the downspout cover is bolt-shaped in appearance, the rubber sealing ring is pressed by a round cover plate at the upper portion of the downspout cover, external threads matched with the internal threads on the downspout are manufactured on the lower portion of the downspout cover, and an inner hexagon hole is formed along the central axis of the downspout cover. The commercial refrigerator downspout structure is applicable to a commercial refrigerator.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention 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 solution adopted in the present invention 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 invention has the beneficial effects as follows: the present invention 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, 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.

The specific embodiment
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.
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 scope of protection of present invention is not limited to introduce herein, all various forms of conversion of doing based on the present patent application the scope of the claims and description and replacement, all belongs to the scope that patent of the present invention contains.
