Wherein: the upper bank of 1-, 2-guide rail, 21-upper convex portion, protuberance under 22-, 3-layer door hanging plate, the upper change gear of 4-, 41-annular stop groove I, 5-bottom roller, 51-annular stop groove II, 6-straight line elongated hole, 7-roller mount, 8-spacing hole, 9-positioning plate, 10-bolt hole.
Detailed description of the invention
As shown in Fig. 1 ~ Fig. 6, this crashproof run-resistant elevator landing door that the present embodiment provides, comprises bank 1, guide rail 2 and layer door hanging plate 3.Wherein, guide rail 2 and upper bank 1 one-body molded, namely the two is structure as a whole, and guide rail 2 horizontal arrangement.Described layer door hanging plate 3 by it arrange upper change gear 4 and bottom roller 5 be slidably mounted on described guide rail 2, during practical application, the position bolt of roller mount on straight line elongated hole is fixed, if be subject to external impacts, roller mount is linearly elongated hole slip probably.Straight line elongated hole 6, one roller mount 7 described layer door hanging plate 3 offering oblique extension is slidably mounted on described straight line elongated hole 6, and described bottom roller 5 is rotatably installed in described roller mount 7.The rolling surface of described upper change gear 4 is provided with the annular stop groove I 41 be looped around on this on change gear, the rolling surface of described bottom roller 5 is provided with the annular stop groove II 51 be looped around on this bottom roller, the top of described guide rail 2 is provided with the upper convex portion 21 stretched in described annular stop groove I, and the bottom of described guide rail 2 is provided with the lower protuberance 22 stretched in described annular stop groove II.
Due to the rolling surface of upper change gear 4 and bottom roller 5 being respectively arranged with annular stop groove I 41 and annular stop groove II 51, thus achieve change gear 4 and spacing between bottom roller 5 and guide rail 2, effectively reduce the possibility that layer door hanging plate 3 comes off from guide rail 2.
Although the annular stop groove I 41 that upper change gear 4 and bottom roller 5 are arranged and annular stop groove II 51 effectively reduce the possibility that layer door hanging plate 3 comes off, but because the up and down upright position of roller mount 7 on layer door hanging plate 3 can change, if roller mount 7 under external force linearly elongated hole 6 glide downwards to lowermost end, the position of bottom roller 5 also just moves down thereupon, it is very large that the vertical distance gone up like this between change gear 4 and bottom roller 5 will be drawn, when layer door hanging plate 3 is subject to diagram impact and upwards moves right, upper change gear 4 probably comes off from guide rail 2, and cause coming off of whole layer door hanging plate 3.
In order to avoid the generation of above-mentioned phenomenon, the present embodiment has done again further improvement to above-mentioned elevator landing door: with reference to shown in Fig. 2, this example positioning plate 9 that adopted bolt to fixedly mount on described layer door hanging plate 3, be specially, layer door hanging plate 3 is shaped with the bolt hole 10 for mounting limit plate 9, bolt to penetrate in this bolt hole thus layer door hanging plate 3 and positioning plate 9 is fixed together.This positioning plate 9 offers the both sides being positioned at described straight line elongated hole 6 and parallel two linear spacing holes 8 with straight line elongated hole 6, described roller mount 7 part stretches in described spacing hole 8 and also can slide along spacing hole 8, and the length of described spacing hole 8 is less than the length of described straight line elongated hole 6.So, due to the position-limiting action of spacing hole 8, during roller mount 7 glide downwards, the lowermost end of spacing hole 8 can only be slided at most, and the lowermost end of straight line elongated hole 6 can not be slided into, that is, the downstream position of roller 5 is restricted, and the maximum normal distance between upper change gear 4 and bottom roller 5 obtains reduction.In practical application, when making layer door strap 3, choose reasonable good spacing hole 8 size, during to ensure that the roller mount 7 of bottom roller 5 goes downwards to spacing hole's 8 lowermost end, mobile layer door strap 3 also can not make the upper convex portion 21 above guide rail 2 depart from annular stop groove I 41 straight up.
Described positioning plate 9 is between roller mount 7 and layer door hanging plate 3.Because positioning plate 9 is bolted on layer door hanging plate 3, so dismounting can be carried out easily.
When layer door hanging plate 3 splits from upper bank 1 by needs, only the bolt be fixed between roller mount 7 and straight line elongated hole 6 need be unclamped, roller mount 7 just can depart from spacing hole 8 completely, and can slide the lowermost end to straight line elongated hole, and such layer door hanging plate 3 just can split from upper bank 1.
In the present embodiment, every block layer door hanging plate 3 is provided with altogether two upper change gears 4 and two bottom rollers 5.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
