The utility model relates to a kind of elevator landing door, comprise a head, be arranged on roller on a head and anti-biasly take turns, and with described roller with anti-biasly take turns fixing link plate, described door head comprises base portion and protrudes out forward the rail portion of formation from described base portion, described roller and anti-bias take turns be arranged in described rail portion and in described rail portion sway, the two ends up and down of described rail portion are respectively to being bent to form bending part outward, described link plate extends back and has a pair hook part at least, described hook part is the corresponding both sides being arranged on described bending part respectively, the eave tile portion of described hook part is positioned at described bending part rear, and described eave tile portion blocks by the orthogonal projection of described bending part at least partly.
Further, described roller and anti-biasly take turns the both sides being oppositely arranged on bending part, described roller is arranged on described anti-bias top of taking turns, and described roller is convex rollers, described anti-bias wheel is taken turns for spill is anti-bias, and described bending part has with convex rollers and spill is anti-bias takes turns the arcwall coordinated.
Further, described roller and described anti-bias wheel are fixed on link plate by rotating shaft.
Further, there is gap between described hook part and door head.
Further, described hook part is arranged in the mode misplaced up and down on link plate.
By such scheme, the utility model at least has the following advantages: elevator landing door provided by the utility model, bending part rear is arranged on owing to link plate having a pair hook part at least, and described eave tile portion blocks by the orthogonal projection of described bending part at least partly, therefore, when link plate is in rail portion during sway, can effectively prevent link plate from coming off from rail portion, improve the safety in elevator use procedure, and this device fabrication accuracy requirement is not high, technique is simple.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Fig. 2 is the assembly drawing of door head and link plate in Fig. 1;
Wherein: 1-door head, 11-base portion, 12-rail portion, 13-bending part, 2-roller, 3-is anti-bias to take turns, 4-link plate, 5-a pair hook part, 51-eave tile portion, 6-rotating shaft.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, elevator landing door described in the utility model to comprise 1, to be arranged on 1 on roller 2 and anti-biasly take turns 3 and with described roller 2 with anti-biasly take turns 3 fixing link plates 4.Wherein, described door 1 comprises base portion 11 and protrudes out forward the rail portion 12 of formation from described base portion 11, and the two ends up and down of described rail portion 12 are bent to form bending part 13 respectively to outer arcuate.Described roller 2 and anti-biasly take turns the both sides that 3 are oppositely arranged on bending part 13, described roller 2 be arranged on described anti-bias take turns 3 top, described roller 2 is convex rollers, describedly anti-biasly takes turns 3 for spill is anti-bias and takes turns 3, and described bending part 13 has with convex rollers 2 and spill is anti-bias takes turns 3 arcwalls coordinated.Described roller 2 is anti-biasly taken turns 3 with described and is fixed on link plate 4 by rotating shaft 6, described roller 2 and anti-bias take turns 3 to be arranged in described rail portion 12 and in rail portion 12 sway, meanwhile, link plate 4 is with roller 2 and anti-biasly take turns 3 opposite rail portion 12 sway, time mobile described roller 2 and anti-bias take turns 3 respectively with vertical folding turn of bilge 13 close contact of described rail portion 12, thus realize roller 2 and anti-bias to take turns between 3 and rail portion 12 spacing, effectively prevent link plate 4 opposite rail portion 12 from occurring loosening and coming off from rail portion 12.
See Fig. 2, described link plate 4 has extended back a pair hook part 5, and described hook part 5 tears formation backward on link plate.In other embodiments, described hook part 5 is multipair setting.Described hook part 5 is the corresponding both sides being arranged on described bending part 13 respectively, and described hook part 5 is arranged in the mode misplaced up and down on link plate 4.The eave tile portion 51 of described hook part 5 is positioned at described bending part 13 rear, and described eave tile portion 51 blocks by the orthogonal projection of described bending part 13 at least partly.When link plate 4 is in rail portion 12 during sway, the eave tile portion 51 of described hook part 5 can carry out effectively spacing to link plate 4, even if when link plate 4 is because rocking before and after various factors appearance, described bending part 13 can stop the disengaging of hook part 5, thus effectively reduces the possibility that link plate 4 comes off from rail portion 12.
Gap is there is between described hook part 5 and door 1, namely, when link plate 4 does not occur acutely to rock, described hook part 5 does not contact with described rail portion 12, to avoid link plate 4 to rub with rail portion 12 in moving process in rail portion 12, hinder the effective slip of link plate 4 in rail portion 12.
In sum, bending part 13 rear is arranged on by the hook part 5 on link plate 4, and eave tile portion 51 blocks by the orthogonal projection of bending part 13 at least partly, therefore, when link plate 4 during sway, effectively can prevent link plate 4 from coming off from rail portion 12, improve the safety in elevator use procedure in rail portion 12, and this device fabrication accuracy requirement is not high, technique is simple.
Elevator landing door provided by the utility model; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within the utility model protection domain.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
