Abstract
The utility model relates to an anti-rust cap and a leakage-proof gasket. The anti-rust cap comprises a hollow cylinder, wherein the upper end face of the cylinder is closed through a top cover, while the lower end face of the cylinder is opened. The diameters of the upper end face and the lower end face of the cylinder are unequal. The leakage-proof gasket comprises a circular sheet body, wherein a cone-shaped hole is formed in the center of the circular sheet body. The anti-rust cap and the leakage-proof gasket provided by the utility model are simple in structure, and the anti-rust cap and the leakage-proof gasket are used, so that a screw is not directly contacted with outside and is not contacted with rain, wind and light, thereby, the sealing performance is realized and the service life is prolonged.
Description
Technical field
The utility model relates to cap and pad technical field, especially relates to a kind of antirust cap and anti-drain gasket.
Background technology
The pad method of existing single watt, plastic made tile, Sandwich tile (C type watt) is the fixed bolster combination with metal basically, comprise that some accessories all are metal products, most screw all is directly to expose outside, aggravated getting rusty, rotting of whole metal fixed bolster so more, time for a long time can be serious leak and plate, tiling breakage, particularly south the typhoon here, the frequent accessory of fixed bolster that often causes of rainwater are sent out the rust back earlier to whole fastening devices breakage.
Therefore, get rusty in order to prevent accessory, the appearance of a kind of antirust cap and anti-drain gasket is necessary.
The utility model content
The utility model proposes a kind of antirust cap, solved the exposed problem of screw in the prior art.
The utility model has also proposed a kind of and above-mentioned antirust anti-drain gasket that emits lid to be used, and has solved stationarity and the sealing of screw in the prior art.
Antirust lid and the leakproof pad of emitting in the utility model is used in combination, and makes screw can not directly contact the external world, can not reached sealing by rain, wind, light contact, increases application life.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of antirust cap comprises hollow cylinder, and the upper surface of described cylinder is airtight by top cover, and the lower surface of described cylinder is uncovered, and wherein, the upper surface of described cylinder and the diameter of lower surface are unequal.
As optimized technical scheme, the diameter of described upper surface is less than the diameter of described lower surface.
As optimized technical scheme, the inner ring of the lower surface of described cylinder is provided with fillet.
The anti-drain gasket that a kind of and above-mentioned antirust cap is supporting comprises circular lamellar body, is provided with the hole at the center of described circular lamellar body, and described hole is bellmouth.
As optimized technical scheme, be provided with fillet at an end face of described circular lamellar body.
As optimized technical scheme, described fillet is arranged on the end face of the big side of the bore dia of circular lamellar body.
Beneficial effect
The utility model is simple in structure, uses by antirust cap and anti-drain gasket, makes screw can not directly contact the external world, can not reached sealing by rain, wind, light contact, increases application life.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-2, a kind of antirust cap comprises hollow cylinder 1, the upper surface 2 of cylinder 1 is airtight by top cover 3, the lower surface 4 of cylinder 1 is uncovered, and wherein, the upper surface 2 of cylinder 1 and the diameter of lower surface 4 are unequal, the diameter of upper surface 2 is less than the diameter of lower surface 4, lower surface 4 diameter 18mm in the present embodiment, upper surface 2 is 17.3mm, height 11mm, the inner ring of the lower surface 4 of cylinder 1 is provided with fillet 5, and the diameter of fillet 5 is 7mm.
With reference to shown in Figure 3, a kind of anti-drain gasket, should adopt the plastic cement material injection mo(u)lding by anti-drain gasket, comprise circular lamellar body 6, be provided with hole 7 at the center of circular lamellar body 6, hole 7 is bellmouth, is provided with fillet 8 at an end face of circular lamellar body 6, and fillet 8 is arranged on the end face of the big side of hole 7 diameters of circular lamellar body 6.
In the present embodiment, the inner ring diameter of circular lamellar body 6 is 4.7mm, and race diameter is 13.9mm, thickness 1.5mm.
Shown in Fig. 4-6: a kind of dedicated fixed pad, comprise gripper shoe 9, be provided with at the middle part of gripper shoe 9 and reserve the vacant circular hole 10 of placing screw, be provided with an open column shape projection 11 at the center of gripper shoe 9, in order to place pad, be provided with fillet 12 at the top of columnar projections 11; Be provided with support side edge 13 in the both sides of gripper shoe 9.Big for contact area, alleviate and reduce the Nature disaster to the damage of building, support side edge 13 is 30 °-90 ° with the angle theta of gripper shoe 9, the support side edge 13 in the utility model is 77 ° with the angle theta of gripper shoe 9.
Above-mentioned anti-drain gasket is that plastic cement is made the stationarity sealing that can play screw, antirust cap is to be placed on the middle circular hole screw of dedicated fixed pad, can accomplish rainproof, water, light like this, the practicality that contacts, increased greatly whole single watt, plastic made tile, Sandwich tile (C type watt) dedicated fixed pad of isolated metal screw and external environment.Anti-drain gasket is placed on the inboard fixed screw of dedicated fixed pad and uses; Antirust cap lid is put at the fixed bolster upside and is made screw can not directly contact the external world, can not reached sealing by rain, wind, light contact.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
