Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

An embodiment of the present invention provides an access door, please refer to fig. 1-2, including a fixed frame 1, a movable frame 2 and a connection frame 3, wherein one end of the connection frame 3 is rotatably connected to a first side of the fixed frame 1, the other end is rotatably connected to a second side of the movable frame 2, the first side and the second side are opposite in direction, the movable frame 2 can be stacked on the fixed frame 1, the fixed frame 1 and the first side of the movable frame 2 can be fixed or separated by a first fixing portion 4, and the fixed frame 1 and the second side of the connection frame 3 can be fixed or separated by a second fixing portion 5 along with the first fixing portion 4.

By adopting the structure, the connecting frame 3 is respectively connected with the fixed frame 1 and the movable frame 2 through the two rotating shafts, so that the second fixed part 5 can be opened or closed together with the first fixed part 4, the fixed frame 1 and the movable frame 2 can be synchronously fixed or separated, and a user can open or close the access door only by one-hand operation; the first fixing part 4 and the second fixing part 5 fix two sides of the movable frame 2 at the same time, so that the other side of the movable frame 2 is prevented from being opened after one side of the movable frame 2 is closed, the other side of the movable frame 2 protrudes out of the whole access door, and the stability of the access door can be effectively improved; the movable frame 2 can be integrally stacked on the fixed frame 1, and the attractive appearance is good.

The first side and the second side refer to two opposite sides of the fixed frame 1 and the movable frame 2 in the closed state, that is, the left side and the right side in fig. 2 can be respectively defined as the first side and the second side, and the upper side and the lower side can also be respectively defined as the first side and the second side, in this embodiment, the first side is the left side in fig. 2, and the second side is the right side in fig. 2.

As shown in fig. 1 and 2, in the present embodiment, the first fixing portion 4 is a push switch assembly disposed on a first side of the fixed frame 1 and the movable frame 2, and a user can open the push switch assembly by pressing the movable frame 2 on the side, so that the movable frame 2 on the side can be separated from the fixed frame 1, and the movable frame 2 can be opened more conveniently;

second fixed part 5 is for setting up the magnetism switch module of inhaling in the second side of fixed frame 1 and connection frame 3, break away from fixed frame 1 as the activity frame 2 of first side, and when being continuously drawn open, because the second side of fixed frame 1 and connection frame 3 still keeps fixed by second fixed part 5, the second side of connection frame 3 is connected with activity frame 2, consequently 2 whole just can slopes of activity frame, and the in-process that is continuously drawn open at activity frame 3, connection frame 3 also can break away from the normal position gradually with the fixed position of activity frame 2, make magnetism switch module also opened, activity frame 2 breaks away from thereupon with the second side of fixed frame 1.

It should be understood that the first fixing portion 4 may also be a fixing structure other than a push switch component, and the second fixing portion 5 may also be a fixing structure other than a magnetic switch component. For example, the first fixing portion 4 may also be a clamping structure that is opened and closed by a rotary switch, and the second fixing portion 5 may also be a clamping structure that is opened and closed by an interference fit of an elastic member, and the two can also achieve the above technical effects.

In the embodiment, the connecting frame 3 is rotatably connected with the first side of the fixed frame 1 through the first rotating shaft 6 and is rotatably connected with the second side of the movable frame 2 through the second rotating shaft 7.

Referring to fig. 1 and 2, the first rotating shaft 6 is disposed in the frame body on the first side of the fixing frame 1, and a reserved space is left in the middle for the first fixing portion 4; the second rotating shaft 7 is arranged at the bottom of the frame body at the second side of the movable frame 2, and a certain distance is reserved between the second rotating shaft and the second side edge of the movable frame 2, so that the second fixing part 5 is arranged, and meanwhile, when the movable frame 2 is opened and integrally inclined, the second rotating shaft 7 can be quickly separated from the original position, so that the second fixing part 5 is opened, and the movable frame 2 is integrally separated from the fixed frame 1.

The peripheral dimension of the movable frame 2 in this embodiment is smaller than that of the fixed frame 1.

As shown in fig. 2, the peripheral dimensions of the fixed frame 1 and the movable frame 2 refer to the dimensions of the outermost ring of the fixed frame and the movable frame, and thus, when the movable frame 2 is in a closed state, i.e., when being fixed to the fixed frame 1, the movable frame 2 does not protrude from the fixed frame 1 in all directions, so that the access door can be easily installed, and only the dimensions of the fixed frame 1 need to be considered during installation.

In this embodiment, the connection frame 3 is formed by splicing a plurality of pipes, and a plurality of hollow holes are formed in the middle of the connection frame. As shown in figure 1, so set up, the connection frame 3 can satisfy the intensity demand of access door, and weight is lighter and the cost is lower simultaneously, indirectly reduces the holistic cost of access hole.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
