Abstract

When the anti-leakage bolt is used, the anti-leakage liquid in the inner liquid filling washer is extruded into gaps on the surfaces of the washer, the bolt and the fastener by a method of fastening the bolt, so that the aim of preventing water leakage is fulfilled.

Description

Liquid-filled washer and water-leakage-proof bolt

Technical Field

The utility model relates to a with liquid (having leak protection water function) pour into the packing ring into in, when fastening bolt, the inside liquid (having the prevention of seepage water function) of packing ring is through the extrusion, extrudeing liquid to between packing ring, bolt, the fastener, reaches the effect of leak protection water.

Background art:

at present, the known rubber or silica gel gasket has a certain waterproof effect on the surface of a very flat object, but has a poor waterproof effect on the surface of an uneven object.

Disclosure of Invention

The technical problem to be solved is as follows:

the utility model aims at providing an inside packing ring of filling a certain amount of liquid and through the device that the liquid extrusion in the fastening bolt in-process was gone to the packing ring in with the packing ring and is filled up bolt, packing ring, fastener surface space.

The technical scheme is as follows:

the purpose of the utility model is realized like this: the inner circular wall of the gasket filled with liquid is thin and is easily pressed and broken, the outer circular wall, the upper surface wall and the lower surface wall are thick and cannot be pressed and broken, the inner circular wall is pressed and broken through pressing in the process of fastening the bolt, and the liquid is pressed to gaps on the surfaces of the bolt, the gasket and the fastener.

Has the advantages that:

by adopting the scheme, the designed and manufactured gasket can fill liquid into the gaps on the surfaces of the bolt, the gasket and the fastener, so that the aim of preventing water leakage is fulfilled.

Detailed Description

Fig. 1 is made of a softer material, such as silicone or rubber.

In fig. 1, the liquid material for preventing water leakage is filled into the liquid filling space (1) inside the gasket, the thicknesses of the upper surface wall (2) of the gasket, the lower surface wall (3) of the gasket and the outer circular wall (4) of the gasket are all thick and cannot be squeezed to break, and the thickness of the inner circular wall (5) of the gasket is thin and is easy to squeeze to break.

Fig. 3 is a front view of the bolt.

Fig. 4 is a water leakage preventing bolt assembled in fig. 1 and 3.

In fig. 6, a small gap exists between the color steel plate (11) and the thread (16), and water easily permeates into the other side of the color steel plate (11) from the gap between the color steel plate (11) and the thread (16) before the bolt is fastened.

Fig. 7 shows that after the bolt is fastened, the inner wall (5) of the washer is pressed and cracked to form a crack opening (12), and the water leakage-proof liquid flows into the gap (10) between the washer and the bolt from the crack opening (12) and fills the gap, so that water cannot penetrate into the other side of the color steel plate (11) from the tiny gap between the color steel plate (11) and the thread (16) to achieve the purpose of water leakage prevention.

Fig. 2 can be made of a softer material (such as rubber, silicon gel, etc.), or can be made of a metal material with better ductility (such as copper, aluminum, etc.).

In fig. 2, the liquid material for preventing water leakage is filled into the liquid filling space (6) in the gasket, the thickness of the upper surface wall (7) of the gasket and the thickness of the lower surface wall (8) of the gasket are both thicker, so that the gasket cannot be squeezed to be broken, and the thickness of the inner circular wall (9) of the gasket is thinner, so that the gasket can be squeezed to be broken easily.

Fig. 5 is a water leakage preventing bolt composed of fig. 2 and 3.

In fig. 8, a small gap exists between the color steel plate (14) and the thread (17), and water easily permeates into the other side of the color steel plate (14) from the small gap between the color steel plate (14) and the thread (17) before the bolt is fastened.

In fig. 9, the material for manufacturing the gasket has certain ductility, so after the bolt is fastened, the gasket is flattened, the inner wall (9) of the gasket is squeezed and broken to form a crack opening (15), and the anti-leakage liquid flows into a gap (13) between the gasket and the bolt from the crack opening (15) and fills the gap, so that the water cannot permeate into the other side of the color steel plate (14) from a tiny gap between the color steel plate (14) and the thread (17), and the aim of preventing the water leakage is fulfilled.

Claims
