Description
Technical field
The utility model discloses a kind of high-performance sealing up screw, belongs to building unit technical field.
Background technology
In building operations, sealing up screw plays the effect of drawknot template, if but the waterproof effect of sealing up screw is bad, and the position that sealing up screw is set is just easy to occur Seepage, and water can be along screw rod to infiltration within the walls.
Utility model content
The purpose of this utility model is to provide a kind of high-performance sealing up screw of good water-proof effect.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of high-performance sealing up screw, comprise body, on the two ends inwall of described body, be provided with internal thread, the end, two ends of body is all fixedly installed the water-swellable sealing head being communicated with tube cavity, the interlude tube wall of body sets to the concave and forms three equally distributed cannelures, in each cannelure, be all equipped with a seal ring, meanwhile, on the tube cavity position corresponding with each cannelure position, be all equipped with a watertight rubber bar.
As the further setting of such scheme, the described seal ring external diameter that is positioned at centre position is greater than the seal ring external diameter that is positioned at dual-side.So arrange, can further improve waterproof effect of the present utility model.
On the outer wall of described body, and be positioned at the inner side of water-swellable sealing head, be fixed with sealing piece.So arrange, can further improve waterproof effect of the present utility model.
Between described sealing piece and body, be integral structure (being that sealing piece and body are one-body molded), can effectively stop the phenomenon that sealing piece and tube wall junction leak, make waterproof effect of the present utility model better.
A kind of high-performance sealing up screw of the utility model, its be fixedly installed on body end water-swellable sealing head, be arranged on the watertight rubber bar of tube cavity and be arranged on effective combination setting of the seal ring on cannelure, make to the utlity model has good waterproof effect, and simple in structure, cost is low.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of high-performance sealing up screw of the utility model, comprise body 1, on the two ends inwall of body 1, be provided with internal thread 2, the end, two ends of body 1 is all fixedly installed the water-swellable sealing head 3 being communicated with body 1 inner chamber, and the interlude tube wall of body 1 sets to the concave and forms three equally distributed cannelures 4, and each cannelure 4 is interior is all equipped with a seal ring 5, meanwhile, on the body 1 inner chamber position corresponding with each cannelure 4 positions, be all equipped with a watertight rubber bar 6.
For further improving waterproof effect of the present utility model, in the utility model, seal ring 5 external diameters that are positioned at centre position are greater than seal ring 5 external diameters that are positioned at dual-side.
For further improving waterproof effect of the present utility model, on the outer wall of body 1 of the present utility model, and be positioned at the inner side of water-swellable sealing head 3, be fixed with sealing piece 7.For making waterproof effect of the present utility model better, between sealing piece 7 of the present utility model and body 1, be integral structure (being that sealing piece 7 is one-body molded with body 1).
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
