Abstract
The utility model discloses a blind flange. The blind flange is made of aluminum products in a forging and pressing mode and comprises a flange plate in a disc shape, a center hole is formed in the center of the flange plate, one side of the flange plate is provided with three annular convex rings, an installing groove used for installing a seal ring is formed between every two convex rings, and the end face of each convex ring is provided with anti-slipping patterns. The frictional force is increased by arranging the anti-slipping patterns on the convex rings, so that when connected with an assembly part, the blind flange is good in anti-slipping performance and convenient to assemble.
Description
Technical field
The utility model relates to a kind of blank flange.
Background technique
Existing blank flange, conventionally made by stainless steel, heavier, and it comprises discoidal flanged plate, the center of described flanged plate offers center hole, one side of described flanged plate has three annular bead, the mounting groove that is formed for installing seal ring between adjacent flange collar, is connected with assembly parts by link, because flange collar surface is smooth surface, therefore non-skid property is poor, causes installation more inconvenient.
Model utility content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of easy to connect, blank flange that skid resistance is good is provided.
For achieving the above object, the technical solution of the utility model has been to provide a kind of blank flange, formed by aluminium forging and stamping, it comprises and is discoidal flanged plate, the center of described flanged plate offers center hole, one side of described flanged plate has three annular bead, is formed for installing the mounting groove of seal ring between adjacent flange collar, and the end face of described flange collar has anti-skid design.
As preferably, described anti-skid design is reticulate pattern.
As preferably, described anti-skid design is groove.
As preferably, the end face of described groove is plane and/or the conical surface.
As preferably, described flange collar arranges with described center hole is concentric.
As preferably, in the flange collar in the middle of being positioned at, offer some locating slots.
As preferably, some described locating slots are uniformly distributed in described flange collar.
Advantage of the present utility model and beneficial effect are: by anti-skid design is set in flange collar, and increasing friction force, when it is connected with assembly parts, non-skid property is good, easy to assembly.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Wherein: 1, flanged plate; 2, center hole; 3, flange collar; 4, anti-skid design; 5, mounting groove; 6, locating slot.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of blank flange, formed by aluminium forging and stamping, it comprises and is discoidal flanged plate 1, the center of flanged plate 1 offers center hole 2, one side of flanged plate 1 has three annular bead 3, between adjacent flange collar 3, be formed for installing the mounting groove 5 of seal ring, the end face of flange collar 3 has anti-skid design 4, in the present embodiment, anti-skid design 4 is groove, the end face of the groove of outside flange collar 3 is the conical surface, the end face of the groove of two flange collars 3 in inner side is plane, in addition, anti-skid design 4 is reticulate pattern, flange collar 3 and the concentric setting of center hole 2, in flange collar 3 in the middle of being positioned at, offer some locating slots 6, some locating slots 6 are uniformly distributed in flange collar 3.
The utility model, in the time of assembling, insert in center hole 2 and be connected with assembly parts by link, the interior installation seal ring of mounting groove 5 is for the sealing between blank flange and assembly parts, in addition increase the frictional force between flange collar 3 and assembly parts by anti-skid design 4 being set on the surface of flange collar 3, skid resistance is better.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
