Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a novel anti-collision door comprises a door frame 1 and a door leaf 2 hinged to the door frame 1, wherein the door leaf 2 comprises an upper door leaf 21 and a lower door leaf 22 which are detachably connected. Therefore, when the lower door leaf 22 is damaged, only the lower door leaf 22 needs to be detached and replaced, and the whole door leaf 2 does not need to be replaced, so that the resources are saved.

Referring again to fig. 1, the lower door leaf 22 is configured as an upright rectangular plate, and the middle portion of the two plate surfaces thereof is provided with an anti-collision rubber plate 221 in a mirror image manner. The anti-collision rubber plate 221 is a rectangular rubber plate, and the short edge of the anti-collision rubber plate is vertical. Four corner ends of the anti-collision rubber plate 221 are fixed on the lower door leaf 22 through screws; the distance between two short edges of the anti-collision rubber plate 221 is smaller than the length of the long edge of the anti-collision rubber plate, so that the middle part of the anti-collision rubber plate 221 is bulged to be in an arc shape; the parts of the anti-collision rubber plate 221, which are abutted against the lower door leaf 22, are positioned on two different plate surfaces of the anti-collision rubber plate 221, so that the bump shape of the anti-collision rubber plate 221 is uneven; the side of the anti-collision rubber plate 221 away from the hinge of the door frame 1 and the door leaf 2 has a large swelling range.

Referring to fig. 2, a connecting portion 222 having a T-shaped cross section is integrally provided on the top surface of the lower door 22, and the lower door 22 is connected to the upper door 21 via the connecting portion 222.

One side surface of the lower door leaf 22 is provided with a second arc-shaped abutting surface 223, and the second arc-shaped abutting surface 223 is a vertical semi-cylindrical side surface with the diameter equal to the thickness of the lower door leaf 22 and the length equal to the length from the bottom surface of the lower door leaf 22 to the bottom of the connecting part 222.

Referring to fig. 1 and 2, the upper door leaf 21 is a rectangular plate having a thickness consistent with that of the lower door leaf 22, and a T-shaped connection slot 211 is disposed on a bottom surface of the upper door leaf 21, and the connection slot 211 is engaged with the connection portion 222, so that the upper door leaf 21 and the lower door leaf 22 can be slidably connected. The door leaf 2 formed by connecting the upper door leaf 21 and the lower door leaf 22 is rectangular as a whole.

A rectangular window 212 is provided in the upper door leaf 21.

The side that goes up door leaf 21 and second arc butt face 223 and be located the homonymy sets up to first arc butt face 213, and first arc butt face 213 footpath length equals second arc butt face 223 and with the coaxial setting of second arc butt face 223, the length of first arc butt face 213 equals the distance of last door leaf 21 top to spread groove 211 bottom to it is sealed to spread groove 211 one end. During installation, one end of the connecting portion 222 close to the second arc-shaped abutting surface 223 is inserted into the connecting groove 211 from the open side of the connecting groove 211, and the connecting portion 222 slides along the connecting groove 211 to abut against the closed end of the connecting groove 211.

Referring to fig. 3, in order to prevent the lower door 22 from sliding off the upper door 21 in a direction away from the first arc-shaped contact surface 213, a bean-jumping spring 224 is disposed at one end of the top surface of the connection portion 222 away from the second arc-shaped contact surface 223, and a spring hole 214 engaged with the bean-jumping spring 224 is disposed in the connection groove 211.

Referring to fig. 1, the door frame 1 includes two upright stiles 11 integrally formed and a horizontal frame 12 fixedly connected to the top ends of the two stiles 11. A vertical frame 11 is connected with one side of the arc-shaped abutting surface of the door leaf 2 through the door shaft 3.

Referring to fig. 1 and 2, the door shaft 3 is provided with two hydraulic hinges, the two hydraulic hinges are respectively used for connecting the upper door leaf 21 and the lower door leaf 22 with the door frame 1, and the middle shaft of the hydraulic hinge is coaxial with the arc-shaped abutting surface of the door leaf 2. When the door leaf 2 is installed in the door frame 1, the arc-shaped abutting surface of the door leaf 2 abuts against the plane of the door leaf 2 connected with the vertical frame 11, and the door leaf 2 can be opened and closed in the door frame 1 in two directions by an angle of ninety degrees, so that the range for people to pass through is enlarged.

Referring to fig. 2 and 4, specifically, both sides of the hydraulic hinge are respectively inserted into the door frame 1 and the door leaf 2, and are fixed to the door frame 1 and the door leaf 2 by vertically inserting screws through the surfaces of the door frame 1 and the door leaf 2. In order to realize the ninety-degree opening and closing of the door leaf 2, an abdicating cavity for the relative rotation of the two parts of the hydraulic hinge is arranged on the door leaf 2.

In order to further improve the isolation effect of the anti-collision door, a sealing strip is arranged to block the gap between the door frame 1 and the door leaf 2. The sealing strips are rubber strips and are respectively positioned on the door frame 1 and the door leaf 2, wherein two sealing strips respectively positioned on two plate surfaces of the door leaf 2 are vertically arranged on the frame of the door frame 1 hinged with the door leaf 2, and the two sealing strips can cover a gap between the door frame 1 and the door leaf 2 when the door leaf 2 is opened and closed along different directions; the other two surfaces of the door frame 1 facing the door leaf are also provided with sealing strips for covering the gap between the door frame 1 and the door leaf 2 where the sealing strips are located; the bottom of the door frame 1 has no frame, so the bottom sealing strip is arranged at the bottom of the door leaf 2. The existence of sealing strip not only can strengthen the isolation effect of crashproof door, can also reduce the noise of switch door, and has certain shock attenuation effect, can reduce the wearing and tearing of crashproof door, and then prolongs the life of crashproof door.

In the specific application process, because the lower door leaf 22 is detachable relative to the upper door leaf 21 and the door shaft 3, the lower door leaf 22 can be directly detached and replaced when needed, and the whole door leaf 2 does not need to be replaced, thereby saving resources. Meanwhile, the lower door leaf 22 is connected with the upper door leaf 21 in a sliding mode, and a clamping device is arranged at the connecting part of the lower door leaf 22 and the upper door leaf 21, so that convenience in disassembly and assembly is realized on the basis of keeping certain connecting strength. Because the existence of sealing strip, this anticollision door's isolation effect is better.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
