Abstract
The utility model discloses a roller special for a rolling screen, comprising a roller body, wherein the roller body is provided with a plurality of axial flanges which are axially extended along the roller body and have round-rectangle-shaped sections, and further provided with a slot which is axially extended along the roller body to form an axial slot. The utility model uniformly disperses the stress of the roller in the axial direction of the roller to increase the twisting strength and rigidity of the roller. When in use, the blocking head of an upward push resisting track blocking bar is blocked into a slot to fit and contact the upward push resisting track blocking bar with a blocking mouth, so that the assembly and disassembly of rolling doors or rolling windows are convenient and the contact area of the upward push resisting track blocking bar and the blocking mouth is increased; meanwhile, the axial force acted on the roller is uniform to increase the twisting resistance and rigidity of the roller and prolong the service life of the roller.
Description
Technical field
The utility model relates to the special-purpose spool of a kind of roller shutter.
Background technology
Mostly the roller shutter of rolling door or roller shutter window is the composition that is cascaded of the roller shutter sheet with the multi-joint activity, and the roller shutter sheet is arranged in the fixing slideway, and the roller shutter sheet and is that the center moves up and down with the spool on the spool of door or window top.Roller shutter is applicable to public place or dwelling houses such as the commercial shop front, garage, market, hospital, industrial enterprise.Especially door opening is bigger, and the place of ground door body is installed in inconvenience, plays the effect of convenient, fast unlatching.As be used for garage door, market fire resistance rolling shutter door, hangar door.During use, the roller shutter sheet is the center rotation with the spool, but no matter the rotary power of spool is manually still electronic, driving force always is applied directly on the spool, and spool must bear huge radially torsion, especially in moment that spool rotates, radially torsion is bigger, and general rolling door. used spool on the window only is the cylinder interlock shape spool of common material, and the articulation port of this spool is extremely unstable, in use, rigidity that can bear and intensity are all little, and stress is concentrated, easy deformation, cause the roller shutter resistance of motion to become big after the distortion, thereby, further make the spool distortion, finally cause rolling door. window shortening in application life.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, provides that a kind of strength and stiffness are big, anticorrosive, long service life, and can stand the special-purpose spool of roller shutter of bigger radially torsion.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the special-purpose spool of a kind of roller shutter, comprise reel body, and described reel body is provided with along the axially extended a plurality of axial raised lines of reel body.The utility model is provided with a plurality of along the axially extended a plurality of raised lines of reel body at the reel body outer peripheral face, and axial raised line and reel body once-forming, the setting of a plurality of axial raised lines with stressed the axial of spool that be dispersed in, has increased the torsional strength and the rigidity of spool.
Further improve as the utility model, push away being connected of crawler belt card article and spool on preventing for convenience, also be provided with draw-in groove on the described reel body.During use, the dop that pushes away on the crawler belt card article on anti-is snapped in the draw-in groove, so both made things convenient for the installation of rolling door or roller shutter window, also made things convenient for dismounting, so operation and maintenance is all very convenient.
Further improve as the utility model, described draw-in groove extends axially along reel body and forms axial draw-in groove.Axially draw-in groove has increased the length of draw-in groove, the stressed further dispersion when using.
Further improve as the utility model, the cross section of described axial raised line is a round rectangle.In use, the dop that pushes away on preventing on the crawler belt card article is movable in bayonet socket, and axially the fillet of raised line makes movable resistance reduce, and has further reduced frictional dissipation. the reduction noise.
The utility model is a plurality of along the axially extended axial raised line of reel body by being provided with on reel body, with stressed the axial of axle that be dispersed in of spool, has increased the torsional strength and the rigidity of spool.During use, dop on the roller shutter sheet is snapped in the draw-in groove, the roller shutter installation and removal had so both been made things convenient for, operation and maintenance is all very convenient, also increased the contact area that pushes away crawler belt card article and draw-in groove on preventing on the other hand, make to push away the crawler belt card article on anti-and work in coordination with draw-in groove and contact, make spool evenly stressed in the axial direction simultaneously, prolonged the application life of spool.The utility model can be used for rolling door, also can be used for roller shutter window or other need use the place of roller shutter.
Description of drawings
Fig. 1 is the spool cross section structure schematic diagram of embodiment 1.
Fig. 2 for the spool of embodiment 1 with anti-on push away the connection diagram of crawler belt.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Referring to Fig. 1 and Fig. 2, the special-purpose spool of this roller shutter comprises reel body 1, and the outer peripheral face part of reel body 1 outer process vertically forms a plurality of axial raised lines 2, and axially the quantity of raised line 2 is decided according to the actual requirements, be generally between four to ten, present embodiment adopts seven axial raised lines 2; Axially the cross section of raised line 2 is a round rectangle, also is provided with draw-in groove 3 on reel body 1, and draw-in groove 3 is used for connecting and pushes away the crawler belt card article on anti-, pushes away the crawler belt card article on anti-by being fastened in the draw-in groove 3 with the suitable dop 4 of draw-in groove.Draw-in groove 3 extends axially along reel body 1 and forms axial draw-in groove, the length of draw-in groove 3 can equal the axial length of reel body 1, also can be shorter than the axial length of reel body 1, stressed in order to disperse fully, the length of draw-in groove 3 equals the axial length of reel body 1 in the present embodiment.
