Abstract

The lever-type trackless translation linear door belongs to a translation door, in specific, a translation door is provided to realize trackless linear translation using the lever principle. According to the design scheme of the unity model, the tablets are installed on the underbeam of the tablets, an inner cavity is disposed in the underbeam, and rolling wheels are installed on rolling-wheel guide bracket. A downwards convex salient is provided in the middle part of the upper plane of the inner cavity. Two guide bearings are installed on the rolling-wheel guide bracket which contact with two side faces of the convex salient. The unity model realizes trackless rectilinear translation by using the lever balance between the two roll-wheel guide brackets and the door plates. The unity model is characterized by prepared track needless, simple and rapid installment, relatively less noise and more security of the walkers and cars.

Description

The lever track-less translation linear door

Technical field

The utility model belongs to a kind of translation door, is a kind of translation door of utilizing lever balance theory to realize no track rectilinear translation specifically.

Background technology

Existing translation door is generally a sheet bottom road wheel straight line moving in orbit is set, and there is a series of shortcoming in this translation door: 1 track needs pre-buried in advance, will guarantee its levelness, straightness accuracy when pre-buried, and influence the logistics transportation in construction period; What 2 general pre-buried tracks were used is i iron or angle steel, the unsafe factor when therefore having increased pedestrian and vehicle by track; When 3 road wheels were walked in orbit, noise was bigger, and road wheel easily gets rusty, and had had a strong impact on the attractive in appearance of gate.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby designs a kind of novel translation door of utilizing the no track rectilinear translation of principle realization of lever balance.

According to design scheme provided by the utility model, the door sheet is installed on the door sheet bottom beam, and inner chamber is arranged in door sheet bottom beam, and the roller that is installed on the roller guide tray is arranged in inner chamber.

There is the protruding key of downward protrusion at the middle part on plane on inner chamber, and two guide bearings are installed on roller guide tray, and these two guide bearing rolling surfaces are in the contact of the two sides of protruding key.The door sheet is movably located in the portal frame, portal frame is formed by connecting by two root posts that are positioned at a sheet both sides and the cross bar that is positioned at two root posts upper end, upper inner at two root posts is separately installed with two junction plates, on per two relative up and down junction plates directive wheel is installed, the last beam sides of door sheet contacts with directive wheel.

Guide strip is installed at the position that contacts with directive wheel on the upper beam of door sheet.The outside at door sheet bottom beam connects flanging spare, is connected with tooth bar on flanging spare.

The utility model has the advantages that because translation door is the trackless operation, thus need not pre-buried track, quick for installation simple; The performance brilliance contacts because of no wheel and guide rail are rigid, and noise is less, is applicable to frequent open and close; Human oriented design, pedestrian and vehicle by the time safety greatly increase.

The specific embodiment

As shown in the figure, door sheet 4 is installed on the door sheet bottom beam 3, and inner chamber 11 is arranged in door sheet bottom beam 3, and the roller 14 that is installed on the roller guide tray is arranged in inner chamber 11.There is the protruding key 9 of downward protrusion at the middle part on plane on inner chamber 11, and two guide bearings 10 are installed on roller guide tray, and these two guide bearing 10 rolling surfaces are in the contact of the two sides of protruding key 9.Door sheet 4 is movably located in the portal frame 5, portal frame 5 is formed by connecting by two root posts that are positioned at a sheet 4 both sides and the cross bar that is positioned at two root posts upper end, upper inner at two root posts is separately installed with two junction plates 6, directive wheel 8 is installed on per two relative up and down junction plates 6, and the last beam sides of door sheet 4 contacts with directive wheel 8.Guide strip 7 is installed at the position that contacts with directive wheel 8 on the upper beam of door sheet 4.The outside at door sheet bottom beam 3 connects flanging spare 12, is connected with tooth bar 13 on flanging spare 12.

Operating principle of the present utility model is a lever balance theory.Main two strong points that rely on roller guide tray 1 and roller guide tray 2 conduct door sheets 4, these two is to decide according to door opening width and door leaf length by the distance between the roller guide tray 1,2, roller 14 on the roller guide tray 1,2 is positioned at the inner chamber 11 of door sheet bottom beam 3, work to support the door sheet and hold the door sheet, make whole door sheet 4 break away from ground, guaranteed door sheet 4 move left and right on roller guide tray 1 and roller guide tray 2, guarantee the orthostatic of door sheet 4 again by the directive wheel of installing on the portal frame 58, reach the function of open and close door with this.Two groups of guide bearings 10 are installed on roller guide tray 1 and roller guide tray 2, are guaranteed the linearity of moving before and after the translation door.

The course of work of the present utility model is: when door sheet 4 during in the centre position, supporting the last transverse plane of door sheet bottom beam 3 inner chambers by the roller 14 in roller guide tray 1 and the roller guide tray 2, reaching the balance of a sheet 4 with this; When at closing time, promptly door sheet 4 moves right, movable length was above 1/2 o'clock, the right-hand member of door sheet 4 is sagging because of the deviation of gravity center roller guide tray 1 of whole door sheet, roller guide tray 1 plays a part toward upper support, and 2 of roller guide trays are past drop-down door sheet 4, work the effect of pushing down, the right-hand member that guarantees door sheet 4 is not sagging, and left end door sheet is toward upwarping; When opening the door, promptly door sheet 4 is moved to the left, movable length was above 1/2 o'clock, the left end of door sheet 4 is sagging because of the deviation of gravity center roller guide tray 2 of whole door sheet, and at this moment, roller guide tray 2 plays a part toward upper support, roller guide tray 1 is past drop-down door sheet 4, work the effect of pushing down, guarantee that the left end of door sheet 4 is not sagging, the right-hand member of door sheet 4 is toward upwarping.When door sheet 4 move left and right, roller guide tray 1 and roller guide tray 2 checker functions as lever, are guaranteed translation door even running under the condition of not having the wheel trackless.
