Abstract

The utility model discloses a building is grout syringe needle for mending leakage, including the cylinder that link up from top to bottom, the lower extreme of cylinder has a screw rod that link up from top to bottom soon, and the screw rod overcoat has rubber circle and the gasket of card between screw rod and cylinder lower extreme, the through-hole that link up from top to bottom has in the screw rod, and the internal diameter of through-hole is filled in rubber grain and the tower spring of top at rubber grain lower extreme from last to crescent down in the through-hole, and the lower extreme of through-hole has interior bulge and is used for blocking the barb of tower spring lower extreme. The grouting needle for building leakage repair is simple in structure and convenient to assemble.

Description

Grouting needle head for building leakage repairing

Technical Field

The utility model relates to a supplementary work piece of waterproof leaking stoppage for building that cooperation high pressure grouter used specifically says so a building is grout syringe needle for leaking stoppage.

Background

The construction industry is exposed to leaks in walls or other building surfaces, such as subway, tunnel, sewer. The seepage causes the problem of water seepage, and the building surface is easily damaged and easily collapsed in the past, thereby seriously affecting the safety problem. Therefore, the grouting needle has the appearance, and is matched with a high-pressure grouting machine for use, so that chemical liquid is injected into cracks, and the cracks are filled with the chemical liquid to form a waterproof effect. At present, many products are available on the market, but most of the products have the problem of troublesome assembly, a spring and a rubber ball are required to be arranged in a metal needle cylinder, and a screw rod at the tail part is screwed, so that a strict assembly procedure is required to ensure that the assembly cannot be mistaken.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention is directed to: provides a grouting needle head for building leakage repair, which is simple to assemble.

The technical solution of the utility model is that: the utility model provides a building is grout syringe needle for mending leakage, includes the cylinder that link up from top to bottom, and the lower extreme of cylinder has a screw rod that link up from top to bottom soon, and the screw rod overcoat has rubber circle and the gasket of card between screw rod and cylinder lower extreme, the through-hole that link up from top to bottom has in the screw rod, and the internal diameter of through-hole is from last to increasing gradually down, has filled in the through-hole rubber grain and has pushed up the tower spring at rubber grain lower extreme, and the lower extreme of through-hole has interior bulge and is used for blocking the barb of.

Furthermore, the quantity of rubber circle and gasket all is two at least, rubber circle and gasket interval distribution set up a gasket between rubber circle and the cylinder.

Further, the rubber particles are blocked at the middle lower section of the through hole.

Use the utility model provides a building is grout syringe needle for mending leakage, its beneficial effect is: during assembly, firstly, the rubber ring and the gasket are sleeved outside the screw rod, then the upper end of the screw rod is screwed with the needle cylinder, and then the rubber particles and the tower spring are sequentially plugged from the lower end of the screw rod, namely, the assembly is finished, and the structure is simple and the assembly is convenient.

Drawings

Fig. 1 is a schematic cross-sectional view of the present invention;

FIG. 2 is an enlarged view of area A of FIG. 1;

fig. 3 is an exploded view of the present invention.

Shown in the figure: 1-needle cylinder, 2-screw rod, 21-through hole, 211-barb, 3-rubber ring, 4-gasket, 5-rubber grain, 6-tower spring.

Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

as shown in fig. 1-3, a building is grout syringe needle for mending leakage, including cylinder 1 that link up from top to bottom, the lower extreme of cylinder 1 revolves has a screw rod 2 that link up from top to bottom, 2 overcoat of screw rod have the rubber circle 3 and the gasket 4 of card between

screw rod

2 and 1 lower extreme of cylinder, through-hole 21 that link up from top to bottom has in the screw rod 2, the internal diameter of through-hole 21 is from last to increasing gradually down, it has rubber grain 5 and top at the tower spring 6 of rubber grain 5 lower extreme to pack into in the through-hole 21, the lower extreme of through-hole 21 has interior protruding and is used for blocking the barb 211 of tower spring 6 lower extreme, barb 211 is the.

The quantity of rubber circle 3 and gasket 4 is two, and rubber circle 3 and 4 interval distribution of gasket set up a gasket 4 between rubber circle 3 and the cylinder 1, and rubber circle 3 and gasket 4 play sealed effect.

The rubber particles 5 are blocked at the middle lower section of the through hole 21. When the syringe 1 is filled with the grout, the grout pushes the rubber particles 5 open to open the through holes 21, the tower spring 6 is compressed, and after the completion of the grouting, the rubber particles 5 are restored by the elastic force of the tower spring 6 to block the through holes 21.

During assembly, the rubber ring 3 and the gasket 4 are sleeved outside the screw rod 2, then the upper end of the screw rod 2 is screwed with the needle cylinder 1, and then the rubber grain 5 and the tower spring 6 are sequentially plugged from the lower end of the screw rod 2, namely the assembly is finished.

It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.

Claims
