Abstract

The utility model relates to the technical field of roller shutter doors, in particular to a polygonal roller of the roller shutter door. The polygonal roller comprises a roller body. The roller body comprises an outer wall of the roller body, and the outer wall of the roller body is polygonal. The outer wall of the roller body is regularly polygonal. By the arrangement, roller deflection is reduced by changing the roller in shape, so that the roller body can bear heavier curtain surfaces of the roller shutter doors, materials needed in mounting of the curtain surfaces of the roller shutter doors are fewer, steel is saved, and cost is lowered.

Description

Polygon rolling door cylinder and rolling door

Technical field

The utility model relates to electric rolling door field, in particular to a kind of polygon rolling door cylinder and rolling door.

Background technology

Electric rolling door be with multi-joint activity door a sheet be cascaded, starting is driven by motor unit, door curtain, in fixing slideway, rotates and rolls curtain face with door top cylinder, is applicable to the place of larger, the inconvenient installation ground door of the door opening bodies such as the business shop front, garage, market.

Electric rolling door is mainly by cylinder, electric roll-up door mechanism (motor), door curtain, supporting plate and composition of the control system.Cylinder is mainly responsible for door curtain to roll, and has carried the weight of all door curtains.As shown in Figure 1, the cylinder cross section of existing rolling door is circular, and the cylinder of this structure has following defect:

(1) cylinder amount of deflection (during flexural deformation, the cross section centre of form is along the linear displacement with axis vertical direction) is relatively large, and while causing curtain face to be rolled, door curtain is sagging obviously.

(2) in order to ensure door curtain not sagging (reducing door curtain sag), can only increase cylinder thickness or diameter.Increasing cylinder thickness can cause cylinder manufacturing cost to increase.

Utility model content

It is polygonal rolling door cylinder that the purpose of this utility model is to provide a kind of cross section, to solve the problem that above-mentioned circular drum amount of deflection is large, cylinder cost is high.

The polygon rolling door cylinder that the utility model provides, comprises cylinder body, and cylinder body comprises cylinder body outer wall and cylinder inner body wall, and cylinder body outer wall is polygon.Preferably, described cylinder body outer wall is regular polygon.

The utility model provides a kind of rolling door simultaneously, comprises polygon rolling door cylinder, motor, door curtain, supporting plate and control system.

The technique effect that the utility model is realized: the polygon rolling door cylinder that the utility model provides, by the change to cylinder shape, reduced cylinder amount of deflection, reduce the sag of door curtain, without reducing door curtain sag by increasing cylinder external diameter, made the weight of cylinder institute carry rolling screen door curtain face of same thickness, same external diameter, same length larger, be the required material of the rolling screen door curtain face of carry identical weight still less, thereby saving steel, have reduced cost, be convenient to install.

Accompanying drawing explanation

Fig. 1 shows the structure of rolling door cylinder in prior art;

The cross section that Fig. 2 shows embodiment to be provided is a kind of structure of polygonal rolling door cylinder;

The cross section that Fig. 3 shows embodiment to be provided is the another kind of structure of polygonal rolling door cylinder.

Mark in figure: 10-cylinder body outer wall, 20-cylinder inner body wall.

The specific embodiment

Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.

The polygon rolling door cylinder that the present embodiment is enumerated, comprises cylinder body, and cylinder body comprises cylinder body outer wall and cylinder inner body wall, and cylinder body outer wall is polygon, and cylinder body is shaped as polygon.For easily manufactured, cylinder body be shaped as regular polygon.The shape of cylinder body is set to polygon, has reduced the amount of deflection of cylinder body, makes cylinder body can carry more heavy weight rolling screen door curtain face.

It should be noted that, inner wall of rotary drum can be circle, polygon or regular polygon, and when inner wall of rotary drum is polygon, the shape of inner wall of rotary drum and cylinder outer wall can be identical or different.Consult Fig. 2, Fig. 3, Fig. 2, Fig. 3 show respectively the rolling door cylinder that is shaped as octagon of the cylinder body of two kinds of structures.Polygon rolling door cylinder shown in Fig. 2, cylinder body outer wall 10 is octagon, and cylinder inner body wall 20 is rounded; Polygon rolling door cylinder shown in Fig. 3, cylinder body outer wall 10 and cylinder inner body wall 20 are all octagon.Polygon rolling door cylinder shown in Fig. 3 is than the polygon rolling door cylinder shown in Fig. 2, and the required material of the rolling screen door curtain face of carrying identical weight still less, is more saved cylinder manufacturing cost.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
