Abstract
The utility model provides a driving connection device for shutter sheets of an automatic curtain wall, which comprises rotating shafts arranged in pairs, wherein the rotating shafts are respectively arranged at both ends of the sheets and are fixedly connected with the side edges of the sheets and are movably connected with a frame. The middle parts of the rotating shafts are respectively provided with a through hole; stretching screws are arranged in the through holes. The section profile of the shaft body of each rotating shaft at one end connected with the sheets forms an equilateral geometric shape; gaps are arranged on shaft walls of the connection parts of sides of the geometric shape. The section profile of the shaft body of each rotating shaft at the other end connected with the frame is circular. The utility model has the advantages that the rotating shaft and the sheets are firmly connected through the modes that the centers of the rotating shafts are provided with the through holes and the rotating shaft walls are provided with the gaps and the mode of utilizing the expansive action of the stretching screws on the rotating shaft gaps; the generation of loose and desquamation phenomena is eliminated; the safety performance is enhanced; the utility model has finished structure, and is simple and practical.
Description
Technical field
The utility model relates to the drive disk assembly of automatic curtain wall, especially automatically the transmission joint of curtain wall louvre blade.
Background technology
The automatic curtain wall of louvered generally is as transmission by connecting rod, drive some blinds and move together, being connected and rotation between blinds blade and the connecting rod generally is that blade pass is crossed and is fixed at the paracentral axle of its both end sides and flexibly connects with framework, connecting rod is connected with turning cylinder, the pulling blade rotation.But this structure can not be suitable for the automatic curtain wall built-in with power transmission, and along with the wearing and tearing of using, the central axis of blade two ends side becomes flexible easily and between the framework, causes situations such as leaf abscission, has potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic curtain wall that power transmission is built-in, transmission joint of the louvre blade of the automatic curtain wall that blade installation is firm, safe of being applicable to for solving above-mentioned the deficiencies in the prior art.
The technical scheme that the utility model provides for achieving the above object is: a kind of transmission joint of automatic curtain wall louvre blade, it comprises the turning cylinder of paired setting, they are located at the two ends of blade respectively, fixedly connected with the side of blade, flexibly connect with framework, can be by rolling bearing being set or by being socketed on the various forms that metallic sheath on the turning cylinder axis body etc. can make turning cylinder and framework produce relative rotation.If adopt the connected mode of metallic sheath, on the turning cylinder axis body with the position of metallic sheath socket on be provided with annular groove, be used to pour into lubrication oil, to reduce pivoting friction and wearing and tearing.
Middle part at turning cylinder is provided with through hole, stretching screw is set in the through hole, the end axis body cross-sectional shape that turning cylinder is connected with blade is equilateral geometry, and the axial wall of each junction, limit of geometric form is provided with breach, and the end axis body cross-sectional shape that turning cylinder is connected with framework is for circular.
Above-mentioned turning cylinder is divided into active rotating shaft and driven spindle, main rotary shaft is provided with the boss that can fixedly connected with fork on an end end face that is connected with framework, the shape of boss cross section matches with shape of through holes on the fork, so that main rotary shaft can be driven by fork easily by boss.
The beneficial effects of the utility model are: by the breach of offering of through hole and rotation axial wall is set at the turning cylinder center, utilize the expansion of stretching screw for the turning cylinder breach, turning cylinder is connected securely with blade, eliminated the generation of loose or dislocation phenomenon, improved security performance, delicate structure, simple and practical, have good comprehensive benefit.
The utility model is further elaborated by embodiment below in conjunction with accompanying drawing, but embodiment does not limit protection domain of the present utility model.

The specific embodiment
Embodiment 1:
As shown in Figure 1 and Figure 2, the transmission joint of automatic curtain wall louvre blade described in the utility model, it comprises the turning cylinder 5 of paired setting, be divided into active rotating shaft 51 and driven spindle 52, they are located at the two ends of blade 3 respectively, fixedly connected with the side of blade 3, and framework 4 between flexibly connect by the copper sheathing 10 that is socketed on the turning cylinder 5.
As shown in Figure 3, the end axis body cross-sectional shape that turning cylinder 5 is connected with blade 3 is square, and the axial wall of each junction, limit of square is provided with breach 15, and the end axis body cross-sectional shape that turning cylinder 5 is connected with framework 4 is for circular.As shown in Figure 4, turning cylinder 5 middle parts are provided with through hole 7, and stretching screw 8 is set in the through hole 7.
As shown in Figure 5, between the two ends of the automatic blade 3 of curtain wall blinds and framework 4 turning cylinder 5 is set, the relevant position of blade 3 and framework 4 is provided with the hole that is complementary with turning cylinder 5.During installation, earlier in the through hole 7 of turning cylinder 5, insert stretching screw 8, load onto copper sheathing 10 in its outside, passing framework 4 then is fit into turning cylinder 5 square ends in the hole of blade 3 sides, screw on nut 13 at stretching screw 8, fastening along with nut 13, the afterbody of stretching screw 8 can strut the breach 15 of turning cylinder 5, produce expansion, make turning cylinder 5 and blade 3 firm being connected.
Be connected with framework 4 at main rotary shaft 51 on the end face of an end and be provided with the boss 9 that to fixedly connected with fork 6, boss 9 cross sections is shaped as square in the present embodiment, match with the shape of through holes on the fork 6, fork 6 and connecting rod 12 pin joints, when power set drivening rod 12 produced displacements, connecting rod was stirred fork 6, and fork 6 changes into swing offset with straight-line displacement, by boss 9 main rotary shaft 51 is rotated, thereby the louvre blade of curtain wall is realized opening or shutoff operation automatically.
Embodiment 2:
As shown in Figure 3, Figure 4, the transmission joint of the automatic curtain wall louvre blade described in the embodiment 1, the inner surface of the external surface of its turning cylinder 5 and copper sheathing 10 relevant positions, be provided with annular groove 11, the lubrication oil of can annotating in it, so that pivoting friction is littler, reduce the wearing and tearing of device simultaneously and reduce blinds the noise when rotating, the performance and the life-span of improving automatic curtain wall.
