Abstract

The utility model relates to a rail-less automatic telescopic door, which is suitable for commodious inlets and outlets. The utility model comprises a door piece, a telescopic rack which is hinged with the door piece and a machine head. The utility model is characterized in that the telescopic rack is a long rod integration type telescopic rack, and flat ground travelling wheels are arranged on the lower ends of the machine head and the door piece. In addition, the door piece can be formed by inserting and assembling rectangular materials; star-shaped inner sliding grooves are arranged on the corresponding inner side of the front column and the rear column of the door piece. The utility model has the advantages of reasonable structure, beautiful appearance, good linking performance, uniform and nimble expansion and contraction, high travelling precision, convenient installation and convenient use. The utility model can be made into a straight type structure and a cambered structure.

Description

The automatic retractable door of trackless

The utility model relates to a kind of automatic retractable door of trackless that is suitable in the import and export use of spaciousness, and it has good, the easy to install characteristics of runnability.

Automatically retractable door compares with traditional gate that to have a switch flexible, easy to use, the characteristics of good looking appearance.Existing automatic retractable door is usually by the door sheet, forms with a hinged expansion bracket of door sheet and the head that drives the walking of door body, and whole retractable door need could realize linear running by two tracks of ground laying.In actual use, the automatic retractable door of this rail operation exists many deficiencies, one, the laying of track need destroy the road surface, install and use all convenient inadequately; Two, be easy to take turns derailing or not the phenomenon of rail, the flexible operation of influence door; Three, the connecting rod in the expansion bracket is a quarter butt, is hinged with two film gate sheets respectively, and the whole linkage of door is poor; Four, door be provided with in the sheet with the hinged chute of expansion bracket be the U type, easy so hinged slip cap is skidded off outside the groove, cause a body flexible malfunctioning; In addition, the flexible track of existing automatic retractable door is linear and can not be arc, and style is comparatively single.

Task of the present utility model be to provide a kind of rational in infrastructure, functional performance good, the automatic retractable door of trackless easy for installation.

Task of the present utility model is realized by following technical scheme: it include a sheet 2, with a door sheet hinged expansion bracket 3 and a head 1, its difference is that expansion bracket is a stock integrated type expansion bracket, is installed on the level land travelling wheel in the lower end of head and door sheet.

Press such scheme, corresponding inboard setting of the forward and backward column of door sheet 2

The internal chute of type like this can be more reliable hinged with the slip cap on the hinge bar, and whole door sheet can be by being provided with The rectangle tubing of type internal chute is spliced and is formed.

According to above-mentioned scheme, because the utility model has adopted stock integrated type expansion bracket, the telescopicing performance of this expansion bracket and linear precision are good, thereby whole retractable door structure is more become rationally, and it is good to have linkage, evenly flexible, the high characteristic of walking precision guarantees its running orbit so need not to be provided with track, has brought convenience not only for installation and use and do not establish track, the situation that also can avoid taking turns the card rail takes place, and makes the flexible of door become more nimble.

Fig. 6 is the D-D sectional view among Fig. 2.

Fig. 7 is the plan structure figure of another embodiment of the utility model.

An embodiment of the present utility model is shown in Fig. 1,2,3,4,5,6, constitute by head 1, door sheet 2 and expansion bracket 3, the both sides, lower end of head are equipped with the active level land travelling wheel 5 that links with drive unit, the 1-2 sheet is equipped with passive level land travelling wheel 4 at the interval, both sides, lower end of door sheet, the level land travelling wheel can be made of rubber wheel, with the frictional force of increase with ground, prevents to skid, door sheet 2 is spliced assembled by square type tubing, be provided with in the front column 15 and the rear column 14 corresponding inboards of door sheet

The internal chute 11 of type, the top rail of door sheet is flat oblique shape, be decoration door sheet, slot can be set in the outside of door sheet front column 15 and install and to see panel 16, the door sheet is by internal chute and slip cap 7, fixed cover 8 is hinged with expansion bracket, expansion bracket 3 is hinged by hinge bar 6 and forms in two ends end to end by one group of front rod 10 and back link 9, before, side direction between the back link is by spacer sleeve 12 certain interval of staggering, constitute the stock integrated type expansion bracket of many rhombuses that can stretch alone, whole expansion bracket places among the sheet frame chamber, preceding, the interlude intersection of back link is coated with hinge bar 13, the middle part of hinge bar covers spacer sleeve 12, the two ends of hinge bar are equipped with slip cap 7 by rivet 18, and slip cap is the wheel shaft with groove, before the groove of its front end embeds the door sheet, rear column Type internal chute 11, it is hinged reliably that a sheet 2 and expansion bracket 3 are able to, hinge bar 13 two ends of intersection are equipped with fixed cover 8 in the middle of expansion bracket, fixed cover connects firmly with the door sheet mutually by screw 17, as the relative fixed point of door sheet and expansion bracket, the two ends of expansion bracket 3 are joined by the front and rear connecting rods that shortens by joint, and one end and head 1 are hinged, the other end is a fixed end, and direct and fixture is that wall column is hinged.

Second embodiment of the present utility model as shown in Figure 7, it is an automatic retractable door of arc trackless, the track that is its flexible walking is curved, and its design feature is a pair of active level land travelling wheel 5 of the head lower end angle that staggers, and makes the operation that it can arc, meanwhile, the slip cap 7 that install at hinge bar 13 two ends on expansion bracket makes retractable door be convex arc for pre-large post-small, and perhaps slip cap is pre-small post-large, make retractable door be concave arc, remainder is identical with a last embodiment.

In order to make the utility model in long flexible distance, higher walking precision be arranged, can install directive wheel in the centre of head lower end, and follow away gib block of direction relative set on the ground.
