Abstract
The invention discloses a kind of combination fire retardant sleeves, including several round linkage sections, several linkage sections to be sequentially connected；Described linkage section one end offers several circular grooves, and the circular groove is using the center of circle of the linkage section as center array distribution, and the circular groove side offers a strip groove, and the strip groove is using the center of circle of the linkage section as center array distribution；Both sides are respectively equipped with a baffle to the strip groove up and down, and the baffle and the strip groove bottom form a guide rail；The linkage section other end is equipped with several connection terminals, and using the center of circle of the linkage section as center array distribution, the connection terminal is connected by connecting rod with the linkage section connection terminal.By the above-mentioned means, a kind of combination fire retardant sleeve of the present invention, the fire retardant sleeve use composite structure, can locally carry out dismounting maintenance, and it is more laborsaving when not only to install, without cutting specially, and also it is more convenient in maintenance.
Description
Technical field
The present invention relates to pipeline fields, more particularly, to a kind of combination fire retardant sleeve.
Background technique
Casing is generally used for building basement, is for protective conduit or to facilitate the iron ring of Pipe installing, point of casing
Class has rigid casing, soft waterproof casing, steel pipe casing and iron sheet casing etc..
Plastics, rubber tubing are frequently utilized in civil buildings, due to the flammable properties of plastics and rubber so that its often at
For the fuse cord of fire, simultaneously because it is overall structure, it is very inconvenient to install and repair.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of combination fire retardant sleeves, can locally carry out dismounting maintenance.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of combination fire retardant sleeve, if including
Dry circle linkage section, several linkage sections are sequentially connected；
Described linkage section one end offers several circular grooves, and the circular groove is using the center of circle of the linkage section as center array distribution, institute
It states circular groove side and offers a strip groove, the strip groove is using the center of circle of the linkage section as center array distribution；
Both sides are respectively equipped with a baffle to the strip groove up and down, and the baffle and the strip groove bottom form a guide rail；
The linkage section other end is equipped with several connection terminals, connection terminal battle array centered on the center of circle of the linkage section
Column distribution, the connection terminal are connected by connecting rod with the linkage section.
In a preferred embodiment of the present invention, the diameter of the circular groove and the strip groove is of same size.
In a preferred embodiment of the present invention, the size of the connection terminal is matched with the size of the circular groove.
In a preferred embodiment of the present invention, the thickness of the connection terminal is matched with the width of the guide rail.
In a preferred embodiment of the present invention, the spacing of two baffles is matched with the diameter of the connecting rod.
In a preferred embodiment of the present invention, it is equipped with relative to another section of the circular groove in the bar shaped groove bottom
Angle.
It, can be with the beneficial effects of the present invention are: a kind of combination fire retardant sleeve of the present invention, the fire retardant sleeve use composite structure
Part carries out dismounting maintenance, more laborsaving when not only to install, without cutting specially, and more just in maintenance
It is prompt.
Detailed description of the invention
Fig. 1 is a kind of main view for combining fire retardant sleeve linkage section.
Fig. 2 is a kind of rearview for combining fire retardant sleeve linkage section.
Fig. 3 is a kind of right view for combining fire retardant sleeve linkage section.
The components in the drawings are labeled as follows: 1, linkage section；2, circular groove；3, strip groove；4, baffle；5, connection terminal；6,
Connecting rod；7, guide rail；8, chamfering.
Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
It please refers to Fig.1 to Fig.3, the embodiment of the present invention includes: a kind of combination fire retardant sleeve, including several round linkage sections 1,
Several linkage sections 1 are sequentially connected, and using composite structure, can locally carry out dismounting maintenance, when not only to install more
It is laborsaving, without cutting specially, and maintenance when it is more convenient.
The linkage section 1 uses fire-retardant material, so that the casing has flame retarding function.
Described 1 one end of linkage section offers several circular grooves 2, and the circular groove 2 is using the center of circle of the linkage section 1 as center array
Distribution, 2 side of circular groove offer a strip groove 3, and the diameter of the circular groove 2 is of same size with the strip groove 3.It is described
For strip groove 3 using the center of circle of the linkage section 1 as center array distribution, the circular groove 2 is used for the company with the strip groove 3 cooperation
The sliding of connecting terminal 5.
About 3 both sides of strip groove are respectively equipped with a baffle 4, and the spacing of two baffles 4 is straight with the connecting rod 6
Diameter matches, so that only having the connecting rod 6 that can slide between the baffle 4, while playing to the connection terminal 5
The effect of limitation.
The baffle 4 forms a guide rail 7, the thickness of the connection terminal 5 and the guide rail 7 with 3 bottom of strip groove
Width matches, and the connection terminal 5 is slided along the guide rail 7.
1 other end of linkage section is equipped with several connection terminals 5, the size of the connection terminal 5 and the circular groove 2
Size matches, and allows the connection terminal 5 from the guide rail 7 that the circular groove 2 imports the strip groove 3.
For the connection terminal 5 using the center of circle of the linkage section 1 as center array distribution, the connection terminal 5 passes through connection
Bar 6 is connected with the linkage section 1.
It is equipped with chamfering 8 relative to another section of the circular groove 2 on 3 bottom surface of strip groove, described at the chamfering 8 is led
The width of rail 7 narrows, to clamp the connection terminal 5, plays the role of locking.
Compared with prior art, a kind of combination fire retardant sleeve of the present invention, the fire retardant sleeve use composite structure, can be local
