Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, substantive distinguishing features of the present utility model is further described.
The door strap structure of a kind of band anticreep position-limited wheel as shown in Figure 1, it is made up of the door strap 1 affixed with layer door, the roller 2 that is arranged on door strap 1 and the guide rail 3 that coordinates with described roller 2, a position-limited wheel 4 it is rotationally connected on described door strap 1, the radial direction cambered surface both sides of the edge of described position-limited wheel 4 are equipped with anticreep bulge loop 5(as shown in Figure 2), described guide rail 3 is embedded in the anticreep groove 6 between described anticreep bulge loop 5 by its lower edge.
Guide rail 3 upper limb forms the upper guide ribs 9 that coordinates with roller 2, and lower guide ribs 7 lower surface be arranged in parallel with the upper surface of upper guide ribs 9, and can mate and be clamped between roller 2 and position-limited wheel 4.When assembling, upper guide ribs 9 snaps in the annular groove being located at described roller 2 radial arc Middle face so that door strap 1 and layer door mount on guides 3 by roller 2, and it is spacing that roller 2 realizes horizontal anticreep by annular groove sidewall and the conflict of upper guide ribs 9 sidewall；Lower guide ribs 7 snaps in groove 6 so that it is spacing that position-limited wheel 4 realizes horizontal anticreep by groove 6 sidewall and the conflict of lower guide ribs 7 sidewall.
In practical operation, minimum range between described groove 6 bottom surface and annular groove bottom surface should be greater than or equal to guide rail 3 thickness, and the minimum range between described groove 6 bottom surface and annular groove bottom surface refers to the length that roller 2 and position-limited wheel 4 circle center line connecting upper groove 6 bottom surface intercept with annular groove bottom surface；Described groove 6 width is more than lower guide ribs 7 width, and annular groove width is more than upper guide ribs 9 width, preset clearance between groove 6 sidewall and lower guide ribs 7 sidewall, between annular groove sidewall and upper guide ribs 9 sidewall, normally rolls offer for roller 2 or position-limited wheel 4 and facilitates.
In practical operation, described guide rail 3 is in strip, and its lower edge is provided with the linear lower guide ribs 7 mated with described groove 6 width, and described lower guide ribs 7 is embedded in described groove 6, and position-limited wheel 4 is rolled along described lower guide ribs 7.The either segment of strip guide rail 3 is respectively provided with identical thickness, guide rail 3 can be mated be clamped between the fixing roller 2 of spacing and position-limited wheel 4, and strip guide rail 3 has straight upper guide ribs 9 and lower guide ribs 7 so that layer door level is to the most mobile, it is ensured that the smooth folding of layer door.
In practical operation, described door strap 1 is provided with a horizontally disposed connecting shaft 8, and described position-limited wheel 4 is rotatably connected to the outer end of described connecting shaft 8 by the bearing bored a hole in a portion installed therein.
In practical operation, the cross section of described guide rail can be square or C-shaped or work shape, as long as having straight upper guide ribs 9 and lower guide ribs, is regarded as specific embodiment of the utility model.
In practical operation, described groove 6 is ringwise, and along the periphery setting of described position-limited wheel 4, the lateral cross section of described lower guide ribs 7 is mated with the radial cross-sectional profile of described groove 6, and described lower guide ribs 7 two side walls be arranged in parallel with corresponding anticreep bulge loop 5 sidewall respectively.The convenient lower guide ribs 7 of the profile of coupling snaps in groove 6 smoothly, and described groove 6 cross section profile can be various shape:
Embodiment one: groove 6 cross section profile is square, the cross section profile of lower guide ribs 7 is also square, and sidewall is vertically arranged, effectively undertakes the horizontal force being subject to offset layer door.
Embodiment two；Groove 6 cross section profile is that the big bottom land of notch is little, and the cross section profile of lower guide ribs 7 mates with groove 6, owing to groove 6 sidewall is angularly disposed so that the position-limited wheel 4 that stress deviates is had by lower guide ribs 7 leads back to positive effect.Groove 6 sidewall can be plane, it is also possible to for cambered surface, be regarded as detailed description of the invention of the present utility model.
