A kind of weather strip
Technical field
The utility model relates to a kind of weather strip.
Background technology
Section bar is all adopted in the outer moulding wall connection of each steel construction at present, existing section bar mostly is rigid material and makes, section bar can not solve the rigid knuckle of moulding wall angle in use, and rigid section can not well play the effect of sealing in structure wall annexation, and the cost height.
The utility model content
The purpose of this utility model provides a kind of weather strip, to remedy the problem that angle that existing section bar can not make the structure body of wall can not flexible transition.
For achieving the above object, the technical scheme that adopts is: a kind of weather strip, have base plate and two sidewalls, and one of described two sidewall are the entity arc structure of projection, another surrounds a rectangular recess for entity arc structure of depression, two sidewalls and base plate.
A sidewall of described weather strip body rectangular recess is provided with the entity arc structure of projection, and another sidewall is provided with the entity arc structure of depression.
Described weather strip adopts flexible material.
Described weather strip adopts the rubber material.
One of two sidewall of the utility model are the entity arc structure of projection, another is the entity arc structure of depression, two sidewalls and base plate surround a rectangular recess, good realization is to the clamping of moulding wall, the part that leaks outside when weather strip is installed is level and smooth, and it is flexible transition that the structure of two sidewalls makes the angle of moulding wall, can not cause scraping to damage to peripheral apparatus; Weather strip adopts flexible material, can have effectively to contact with body of wall is installed, and has increased sealing effectiveness.

The specific embodiment
Embodiment one
As depicted in figs. 1 and 2, have base plate 2, the first side wall 3 and second sidewall 4, the first side wall 3 is an entity arc structure for projection, and second sidewall 4 is an entity arc structure for depression, and the first side wall 3, second sidewall 4 and base plate 1 surround a rectangular recess 1.
As shown in Figure 3, sealing bar 5 is arranged between first body of wall 6 and second body of wall 7 when mounted, plays the effect of clamping sealing.
Embodiment two
As shown in Figure 4, be that with the difference of embodiment one the first side wall 3 and second sidewall 4 are the entity arc structure of projection, other parts are all identical with embodiment one.
Embodiment three
As shown in Figure 5, be that with the difference of embodiment one the first side wall 3 and second sidewall 4 are the entity arc structure into depression, other parts are all identical with embodiment one.
