Description
Technical field
The invention belongs to the mounting device technical fields of building insulating layer, and in particular to a kind of expansion anchor.
Background technique
With gradualling mature for China's Building technology, generally can all be done at heat preservation to building when construction is built a house
Reason, adds insulating layer between inner wall and exterior wall, to guarantee the comfort of resident, however the building insulating layer of the prior art
Fixing means mainly uses binder to be directly bonded on base material, keeps stability and being firmly bonded property poor, it is difficult to long
Time uses, and part heat preservation layer material is not suitable for being bonded using binder, so to a certain extent also can shadow
Applicability and practicability are rung, while heat bridge cannot be prevented well when being used for exterior-wall heat insulation in the fixed expansion anchor of insulating layer
Effect causes a large amount of heat loss, to influence heat insulation effect.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention is to provide that a kind of structure is simple, the good expansion anchor of stability in use.
The technical solution for realizing the object of the invention is a kind of expansion anchor, including lug cap and pin body, in the pin
It is equipped with cavity in vivo, groove ring is equipped on the outer wall of the pin body, the company of being equipped between the cavity and the groove ring
Connect hole, expansion ring body be equipped in the groove ring, equipped with inflating port in the expansion ring body, the inflating port with it is described
Connection through-hole is connected, and expansion control port is equipped on the lug cap, check valve is equipped in the expansion control port,
Sealing bed course is equipped in the cavity.
Buffering pressing plate is equipped between the expansion ring body and the groove ring, in the buffering pressing plate and the groove ring
Between be equipped with buffer spring.
The expansion ring body is that the sealing of high pressure resistant material is made, and is equipped with wear-resisting wrapping layer in the outside of the expansion ring body.
Air pressure, which is equipped with, in the inflating port and the connection through-hole junction detects alarm.
The present invention has the effect of positive: structure of the invention is simple, convenient to use, can effectively realize building heat preservation
The connection of layer and substrate, and it is equipped with expansion ring body, it can effectively realize the leakproofness at pin, improve the heat preservation effect of insulating layer
Fruit, easy to use, strong applicability, practicability are good.
Detailed description of the invention
In order to make the content of the present invention more clearly understood, right below according to specific embodiment and in conjunction with attached drawing
The present invention is described in further detail, in which:

See Fig. 1, a kind of expansion anchor, including lug cap 1 and pin body 2, cavity 3 is equipped in the pin body 2, in institute
The outer wall for stating pin body 2 is equipped with groove ring 4, connection through-hole 5 is equipped between the cavity 3 and the groove ring 4, described
It is equipped with expansion ring body 6 in groove ring 4, inflating port 7, the inflating port 7 and the connection through-hole are equipped in the expansion ring body 6
5 are connected, and 1 is equipped with expansion control port 8 on the lug cap, and check valve 9 is equipped in the expansion control port 8,
Sealing bed course 10 is equipped in the cavity 3.
Between the expansion ring body 6 and the groove ring 4 be equipped with buffering pressing plate 11, the buffering pressing plate 11 with it is described
Buffer spring 12 is equipped between groove ring 4.
The expansion ring body 6 is that the sealing of high pressure resistant material is made, and is equipped with wear-resisting wrapping layer in the outside of the expansion ring body 6
13。
Air pressure, which is equipped with, with 5 junction of connection through-hole in the inflating port 7 detects alarm.
Structure of the invention is simple, convenient to use, can effectively realize the connection of building insulating layer and substrate, and set
There is expansion ring body, can effectively realize the leakproofness at pin, improves the heat insulation effect of insulating layer, easy to use, strong applicability,
Practicability is good.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And these
Belong to the obvious changes or variations that connotation of the invention is extended out and still falls within protection scope of the present invention.
