Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following instance is used for illustrating the present invention, but is not limited to the scope of the present invention.
In describing the invention, it is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, for instance, it is possible to it is fixing connection, it is also possible to be removably connect, or connect integratedly；Can be mechanically connected, it is also possible to be electrical connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, it is possible to be the connection of two element internals.For the ordinary skill in the art, it is possible to concrete condition understands above-mentioned term concrete meaning in the present invention.
As depicted in figs. 1 and 2; for a kind of draw curtain buffer unit provided by the invention; it includes two spring leafs being mutually butted 1; the described spring leaf 1 arc in evagination; after the docking of two described spring leafs 1 in intermediate muster, the concordant structure in two ends, described spring leaf 1 pressurized can produce inside elastic deformation, in order to provides a small amount of displacement for whole device; thus providing buffer protection for whole device, to avoid huge impulsive force to cause the damage of Keelof green house.
The joint of said two spring leaf 1 is connected by connector, specifically, described connector can be bolt or rivet 2, in the present embodiment, four rivets 2 are adopted to be connected to the joint of said two spring leaf 1 between two, to be connected as one by said two spring leaf 1.
For the ease of being connected with other devices, it is positioned at the evagination place of described spring leaf 1 and is provided with and takes ear 3 for what connect, specifically, take described in two and ear 3 is respectively equipped with through hole.
Preferably, described spring leaf 1 is made up of stainless steel material, to improve the elastic deformability of described spring leaf 1, increases its service life.
As shown in Figure 3, the present invention also provides for a kind of house shading system, it includes the push rod connecting device that push rod 10 is slidably matched and the driving limit device being connected with described push rod connecting device with described push rod 10, it also includes the draw curtain buffer unit as described in technique scheme, described draw curtain buffer unit is connected to described push rod connecting device and drives between the device of limit, wherein, described driving limit device and described push rod connecting device are connected with the ear 3 of taking of described draw curtain buffer unit respectively through securing members such as bolts.
Specifically, one end of described draw curtain buffer unit is taken ear 3 and is connected with described driving limit device by T-bolt 6, packing ring 5 and stop nut 4, its other end is taken ear 3 and is connected with push rod connecting device by bolt 8, stop nut 4, wherein, described driving limit device is generally driving limit aluminium 7, and described push rod connecting device is generally push rod guide rod Connection Card 9.
The operation principle of the present invention: house shading system normally-open and Guan Bi time, described driving limit aluminium 7, draw curtain buffer unit move with described push rod 10, it is achieved the unlatching of house shading system and greenhouse sunshade system and Guan Bi.
Break down or during misoperation in installation and debugging process when drive motor is spacing, such as described driving limit aluminium 7 reaches precalculated position and drive motor is being rotated further, described push rod 10 is driven to continue motion, together with described driving limit aluminium 7 hit with Keelof green house, motion can not be further continued for, now described draw curtain buffer unit is produced extruding with described push rod guide rod Connection Card 9 by described driving limit aluminium 7, the spring leaf 1 of described draw curtain buffer unit produces elastic deformation makes the tooth bar on house shading system and push rod 10 obtain a small amount of displacement space, it is achieved in the buffer protection to this house shading system.
Present configuration is simple, easy for installation, with low cost, it is possible to provide effective buffer protection to house shading system, it is to avoid the Keelof green house in Greenhouse System is impaired and causes economic loss.
