Abstract
The utility model discloses a bottom beam structure of a roller shutter door. The bottom beam structure comprises a cross tube forming the bottom beam and sliding positioning devices mounted at the two ends of the cross tube, wherein the sliding positioning devices are injection-molded once with antiwear plastics, and each sliding positioning device comprises a sliding positioning end and a limiting block; in the operation process, the bottom beam of the roller shutter door is enabled to rise and fall more steadily by virtue of the positioning sliding of two rollers mounted at the sliding positioning ends in a guide groove of the roller shutter door, the bottom beam is not prone to deform, after the roller shutter door rises to the top, the top of the roller shutter door is hooked by the hooked limiting blocks so that the collision of the bottom beam of the roller shutter door and the top of the roller shutter door is reduced, and therefore, the noise generated in the use process of the roller shutter door is greatly reduced.
Description
Technical field
The utility model relates to a kind of rolling door bottom beam structure, especially a kind of not yielding rolling door bottom beam structure blocking.
Background technology
Rolling door has been widely used in market safe antitheft at present, but rolling door in the market uses and but exists the difficulty of sliding.Rolling door, in order to rise and decline smooth and easy sliding, generally arranges guide groove in rolling door both sides, and the two ends of rolling shutter door base beam coordinate location to slide with guide groove.Bottom girder two ends are generally welded by stainless steel, are in operation, and stainless steel bottom girder two ends are easily out of shape, and are stuck in guide groove; Bottom girder two ends and guide groove produce friction simultaneously, and after rolling door rising, bottom girder clashes into top, all can produce very large noise, also can cause rolling door to use generation fault simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rolling door bottom beam structure, especially a kind of rolling door bottom beam structure of not yielding noise decrease.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rolling door bottom beam structure, comprise the transverse tube that forms bottom girder and the slip positioner that is arranged on transverse tube two ends, described slip positioner, once injection molded by wear-resistant plastic, comprise and coordinate the limited block that slides positioning end and fasten with rolling door top sliding up and down with rolling door guide groove, the described positioning end that slides is the shape that is arranged above and below two rollers is installed, and described limited block is barb-like.
The beneficial effects of the utility model are:
Adopt the slip positioner of wear-resistant plastic injection mo(u)lding, in running, position slip by being arranged on two rollers and the rolling door guide groove that slide positioning end, make rolling shutter door base beam rise, decline more steady, be difficult for producing distortion, rolling door rises to behind top, catches on rolling door top by hook-shaped limited block, the shock that reduces rolling shutter door base beam and rolling door top, reduces the noise that rolling door in use produces greatly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of rolling door bottom beam structure embodiment of the utility model.
Fig. 2 is the A-A sectional view of a kind of rolling door bottom beam structure embodiment of the utility model.
Fig. 3 is the lateral view of a kind of rolling door bottom beam structure embodiment of the utility model.
The specific embodiment
Fig. 1 is a kind of rolling door bottom beam structure, comprise the slip positioner 2 that is arranged on transverse tube 1 two ends, slip positioner 2 is once injection molded by wear-resistant plastic, slip positioner 2 has comprised and has coordinated the limited block 3 that slides positioning end 5 and fasten with rolling door top sliding up and down with rolling door guide groove, slides and on positioning end 5, is the shape that is arranged above and below two rollers 4 are installed.
Concrete rolling door bottom beam structure as shown in Figures 2 and 3.
