Abstract
The utility model discloses a trackless electric telescopic door which comprises a door head, a door frame and road wheels arranged below the door head and the door frame. The door frame is composed of a plurality of door rows, and a lower beam of the door frame is provided with three guide devices. One of the three guide devices is of an embedded sliding groove shape, and is installed on the lower beam by a guide rail bracket. The guide devices are parallel to each other, and are installed in a staggered way. The guide rail bracket is composed of a connecting frame, a connecting column and a roller. The connecting frame is connected on the lower beam, the connecting column is installed at the lower part of the connecting frame, and the roller is installed on the connecting column. The utility model changes the defects of the prior trackless telescopic door, and causes a door body to have accurate movement and location as well as high stability when the telescopic door is folded or unfolded; the assembly and the maintenance are convenient.
Description
Technical field
The utility model relates to a kind of automatic door, relates to a kind of railless electric retractable door specifically.
Background technology
At present, because the automatic door series of products have exquisiteness attractive in appearance, switch door characteristics easily, on the compound gate of office, universities and colleges, factory and residential quarters etc., be widely adopted, and along with the fast development of social economy's construction, its market demand is increasing.Sum up, automatic door now of a great variety, but be broadly divided into two big classes, and a class is the rail electric extendable door that track is laid in the ground, another kind of is the railless electric retractable door that has guiding device.Wherein,, more and more be subjected to liking of customer because of need not to lay on the ground track about railless electric retractable door.
About railless electric retractable door, following two patents are arranged in the prior art: the one, patent " the linear running guiding device of railless electric retractable door " (patent No. 200410015338.0), the operating principle of these innovation and creation is to connect a gib block in the head bottom of retractable door, the free end of this this gib block extends to door row direction, length after its length is shunk less than door row, a guide holder that passes for gib block respectively is housed in the bottom of each doorframe of door row, and door comes that gib block passes each guide holder according to this when shrinking.There is following defective in these innovation and creation, a door body lack compression ratio, gib block can be out of shape when causing poor stability, door running body, inoperative when a gib block is gone out, guidance quality is bad when shrinking, wind resistance is poor; Another patent " retractable door " (number of patent application 200710133939.5), the operating principle of these innovation and creation is that the stretching motion of doorframe is to play guide effect by the primary and secondary railroad, described primary and secondary railroad comprises at least one chimeric parent part, be used for guiding and hold being bumped into component, with at least one component that is bumped into, in the motion of chimeric parent part length direction the each several part of mother and sons' parts is embedded in together by being bumped into component slidably, makes doorframe maintain correct linear running state.There is following defective in these innovation and creation, being bumped into component and need being fixed in ground in the primary and secondary railroad, and assembling is laid and is required highly, and maintenance cost is big, lacks practicality.
The utility model content
In order to solve existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of trackless extensible door of design, and its technical scheme is:
A kind of railless electric retractable door, it comprises a head, doorframe and places road wheel under a head, the doorframe, described doorframe is made up of several rows, it is characterized in that: described doorframe lower transverse beam is provided with three guiding devices, described guiding device is a kind of embedded chute form, be installed on the lower transverse beam the parallel and arranged in dislocation of described each guiding device by guide rail bracket.
Above-mentioned guide rail bracket is made up of link, joint pin and roller, and link is installed on the lower transverse beam, and joint pin is installed on the link bottom, and roller is installed on the joint pin.
In addition, for further increasing the doorframe operation stability, can also on the doorframe top rail, also be provided with three guiding devices, described guiding device is a kind of embedded chute form, be installed on the top rail the parallel and arranged in dislocation of described each guiding device by guide rail bracket.
The beneficial effects of the utility model are: at first, it has changed the defective of existing trackless extensible door, makes retractable door superimposed or when launching, the running fix of door body is accurate, and stability is high; The second, guiding device directly is installed on the doorframe lower transverse beam by guide rail bracket, retractable door assembling, easy to maintenance.
