Description

TECHNICAL FIELD

The invention belongs to a fixed or movable closing device used at the position of an opening of a building, a vehicle, a fence or a similar surround, and in particular relates to a door with an embedded protecting device.

BACKGROUND

Typically, when a door is opened, it rotates around door hinges under the action of its own gravity and external force to close automatically, which causes inconvenience to people's life. To solve the problem, a protecting device is designed to facilitate fixing the door at a specific position when it is opened.

However, the structure of the door can be affected and the service life of the door can be shortened due to the defect of unbalanced stress caused when the existing protecting device is externally mounted and positioned on the top of the door sheet. Besides, the protecting device has poor durability due to structural particularity.

SUMMARY OF THE INVENTION

The invention aims at providing a door with an embedded protecting device so as to prolong the service life of the door and the protecting device.

To solve the above problem, according to the technical scheme:

a door with an embedded protecting device comprises a door sheet and a door frame, wherein the door sheet is connected with the door frame through hinges. The door further comprises an elastic sheet and/or an elastic column, and one end of the elastic sheet and/or the elastic column is fixedly connected with the inner side of a vertical frame. A first clamped board and a second clamped board are also arranged inside the door sheet, and the first clamped board and the second clamped board are fixedly connected with the inner side of the door frame to form a hollow area which matches with the elastic sheet and/or the elastic column. The hollow area further includes an opening and a bottom which are positioned on different sides inside the door sheet, and the elastic sheet and/or the elastic column extend/extends into the hollow area from the opening.

Preferably, the door further comprises a bearing, wherein the inner ring of the bearing is fixed on the first clamped board through a fixing device which comprises a bolt.

Preferably, the distance from the bearing to the opening is 0-25 cm.

Preferably, at least one bearing is provided.

Preferably, one bearing is provided, and the difference between the distance from the bearing to the top of the first clamped board and the distance from the bearing to the bottom of the first clamped board is 0-8 cm.

Preferably, the door comprises a first bearing and a second bearing, wherein the first bearing is positioned on the top of the first clamped board, and the second bearing is positioned under the first bearing.

Preferably, the first clamped board and/or the second clamped board form/forms cavities/a cavity with the door panel.

Preferably, the cavities/cavity are/is filled with fillers.

Preferably, two opposite sides of the first clamped board and the second clamped board are smooth surfaces.

The invention has the following technical effects: 1. the elastic sheet and/or the elastic column can be used for filing gaps between the door sheet and the door frame so that accidental injury caused when fingers are pinched by the gaps can be avoided, especially, the door achieves good effects in the aspect of preventing children or seniors unable to get about from being pinched; further, the door can be normally used while avoiding pinching so that the technical effect is obvious; 2. the protecting device is embedded in the door so that unbalanced force of the protecting device and the door can be eliminated and the service life of the protecting device and the door can be prolonged; 3. the protecting device is embedded in the door and therefore gaps which may be produced when an outer door gap protecting device is installed can be avoided; 4. the hollow area defined by the first clamped board and the second clamped board can be used for guiding, thus reducing friction and facilitating door opening; and 5. the bearings are added on the clamped boards, so that friction is reduced, the elastic sheet and/or the elastic column can be easily inserted into the door, abrasion is avoided and the door is easy to use.

DETAILED DESCRIPTION

To describe the content of the invention more clearly and completely, accompanying drawings that can describe the conception of the invention most suitably are provided as below. It is understood that the provided drawings aim to describe the conception of the invention, rather than the design scheme of the invention, and are not to be considered as the limit to the content of the invention.

Embodiment 1

Referring to FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 7, the door with the embedded protecting device comprises the door sheet 1 and the door frame 2, and the door sheet 1 is connected with the door frame 2 through the hinges 8. The door further comprises the elastic sheet 6, wherein the elastic sheet 6 can be replaced by the elastic column, or the door comprises both the elastic sheet 6 and the elastic column, i.e. two or more of them are included, and one end of the elastic sheet and/or one end of the elastic column is fixedly connected with the inner side of the vertical frame 21. The door sheet comprises the first clamped board 41 and the second clamped board 42, wherein the first clamped board and the second clamped board are fixedly connected with the inner side of the door frame to form the hollow area 51 which matches with the elastic sheet 6 and/or the elastic column and includes the opening 52 and the bottom 53. The opening and the bottom are positioned on different sides inside the door sheet, i.e. the hollow area has certain degree of curvature: supposing the four angular vertexes of the cross section of the door are set as A, B, C and D, the vertex close to the elastic sheet is A and the other three vertexes are sequentially B, C and D in clockwise direction, thus the fact that the opening and the bottom of the hollow area are positioned on different sides inside the door sheet means that the bottom 53 of the door sheet is positioned at the position of D or infinitely extends to D, and the elastic sheet and/or the elastic column extend/extends into the hollow area from the opening. When used, the door frame 2 is fixed on the wall 3.

To reduce the friction between the elastic sheet and the clamped boards, the door further comprises the bearing 7, and the inner ring of the bearing is fixed on the first clamped board through the fixing device which comprises the bolt. The inner ring of the bearing can also be fixed on the column, and then one end of the column is fixed on the first clamped board.

In order to enable the bearing to decrease friction better, the distance from the bearing to the opening is 0-25 cm.

At least one bearing is provided. When the door comprises one bearing, according to FIG. 6, the bearing 72 is positioned in the middle of the first clamped board, certainly, the bearing can be arranged right in the middle or in an area near the middle of the first clamped board. When the difference between the distance from the bearing to the top of the first clamped board and that from the bearing to the bottom of the clamped board I is 0-8 cm, friction can be effectively decreased.

As shown in FIG. 5, when two or more bearings are provided, i.e. the door comprises the first bearing 7 and the second bearing 71, the first bearing is positioned on the top of the first clamped board, the second bearing 71 is arranged under the first bearing, and the second bearing 71 can be positioned either at the bottom or in the middle of the elastic sheet 6 and/or the elastic column.

To reduce the weight of the door sheet, the cavities/cavity 9 are/is formed between the first clamped board and/or the second clamped board and the door panel.

In order to decrease noise generated when the door is opened or closed, the cavities/cavity are/is filled with the fillers.

In order to reduce the friction between the elastic sheet 6 and the clamped boards to facilitate use, the two opposite sides of the first clamped board and the second clamped board are smooth surfaces.
