Abstract
The utility model discloses a kind of European rolling door bottom girder limit pulley, door body bottom girder when comprising pulley, pulley base, screw and install, described pulley base is connected by screw on door body bottom girder, and described pulley and pulley base link together.The utility model by adding top sheave at door body bottom girder two ends, when making a body double swerve directly and rail contact be pulley, pulley can roll in orbit freely, thus can not cause a body hair fastener, greatly increases ease of use and the application life of door.And this pulley structure is simple, installs very convenient, it is the first-selection of corollary apparatus during rolling door use.
Description
Technical field
The utility model relates to a kind of rolling door running gear, especially a kind of European rolling door bottom girder limit pulley.
Background technology
At present about rolling door bottom girder limit pulley also without this device, door body due to rolling door runs in the track on both sides, door body is in rising or decline process, have the situation of double swerve, rock and easily cause a sheet and track friction hair fastener, cause a pad wear or damage, increase maintenance probability, reduce the application life of door.
Utility model content
For the problems referred to above, the present invention aims to provide a kind of European rolling door bottom girder limit pulley.
For realizing this technical purpose, the solution of the present invention is: a kind of European rolling door bottom girder limit pulley, door body bottom girder when comprising pulley, pulley base, screw and install, described pulley base is connected by screw on door body bottom girder, and described pulley and pulley base link together.
As preferably, adopt roller bearing to connect between described pulley and pulley base, pulley flexibility is stronger.
As preferably, described pulley base two ends use a screw to be fixedly connected on a body bottom girder respectively.
The present invention by adding top sheave at door body bottom girder two ends, when making a body double swerve directly and rail contact be pulley, pulley can roll in orbit freely, thus can not cause a body hair fastener, greatly increases ease of use and the application life of door.Pulley stand and pulley all adopt 304 stainless steels to make, and reach more than 15 years application life.And this pulley structure is simple, installs very convenient, it is the first-selection of corollary apparatus during rolling door use.
Accompanying drawing explanation
Fig. 1 is the installation effect schematic diagram of utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing basis and specific embodiment, the present invention is described in further details.
As shown in Figure 1, the one European rolling door bottom girder limit pulley of the embodiment of the present invention, door body bottom girder 4 when its overall structure mainly comprises pulley 1, pulley base 2, screw 3 and installs, described pulley base 2 is connected on a body bottom girder 4 by screw 3, and described pulley 1 and pulley base 2 link together.
As preferably, adopt roller bearing to connect between described pulley 1 and pulley base 2, pulley flexibility is stronger.
As preferably, described pulley base 2 two ends use a screw to be fixedly connected on a body bottom girder 4 respectively.
The present invention by adding top sheave at door body bottom girder two ends, when making a body double swerve directly and rail contact be pulley, pulley can roll in orbit freely, thus can not cause a body hair fastener, greatly increases ease of use and the application life of door.Pulley stand and pulley all adopt 304 stainless steels to make, and reach more than 15 years application life.And this pulley structure is simple, installs very convenient, it is the first-selection of corollary apparatus during rolling door use.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
