Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present embodiment provides an anti-collision heat-resistant wooden fireproof door, which includes a door frame 1, and a fireproof door main body 2 rotatably installed inside the door frame 1.

Wherein, for the convenience at 1 internal rotation main part 2 of door frame, the side fixed mounting of door frame 1 has a hinge 4 that is used for rotating main part 2, and hinge 4 threaded connection is on door frame 1 and main part 2.

The door frame 1 and the main body 2 are preferably made of fireproof and flame-retardant wood, and the fireproof and heat-resistant functions are achieved through the material.

In order to conveniently open and close the fireproof door, handles 23 are fixedly arranged on the two sides of the main body 2 close to the edges, and the fireproof door can be opened by pulling the handles 23.

In order to prevent the main body 2 from being damaged by an impact, a damper plate 3 is movably mounted on one surface of the main body 2.

Wherein, the recess 21 that matches with damper plate 3 is seted up to the one side of main part 2, damper plate 3 slidable mounting in recess 21, and recess 21 internal fixation installs elastic component 31, and the one end fixed connection damper plate 3 of elastic component 31 is used for providing elasticity to damper plate 3.

The elastic members 31 are preferably arranged in a plurality of rectangular arrays and uniformly distributed in the grooves 21, and the elastic members 31 are preferably arranged as springs, but not limited to springs, and elastic mechanisms such as metal elastic sheets can be adopted.

When the fire door is impacted, the impact force is collided on the damping plate 3, the moving speed of the damping plate 3 close to the main body 2 is buffered by the elastic member 31, and the impact on the main body 2 is reduced.

In order to make the damping plate 3 stably approach the main body 2 after being impacted, sliding blocks 33 are fixedly connected to both sides of the damping plate 3.

Wherein, the inside lateral wall of recess 21 is seted up the spout 22 that matches with slider 33, slides and then makes damper plate 3 stably be close to main part 2 in spout 22 through slider 33, slides in spout 22 through slider 33 and still removes damper plate 3 and carries on spacingly, prevents damper plate 3 and breaks away from recess 21.

In order to further reduce the impact on the body 2, a cushion cotton 32 is fixedly installed in the groove 21.

The damping cotton 32 is preferably made of high temperature resistant glass fiber cotton, but is not limited to this material, and may be made of ceramic heat insulation cotton, so long as it is soft, elastic and high temperature resistant.

In order to facilitate the installation of the elastic member 31, the damping cotton 32 is provided with a through hole 321 matching with the elastic member 31.

In order to limit the rotation of the main body 2 in the door frame 1, a stop strip 11 and a doorsill 12 are fixedly connected in the door frame 1.

Wherein, blend stop 11 fixed connection is close to limit edge department in 1 inside upper end of door frame and both sides, and threshold 12 fixed connection is close to limit edge department at 1 inside lower extreme of door frame, and when main part 2 rotated and closed, one side contact laminating blend stop 11 and threshold 12 of main part 2, and then carried on spacingly to 2 turned angle in main part.

The door seam of the fire door is also shielded by the bar 11 and the door sill 12, thereby preventing smoke from passing through the fire door in the event of a fire.

To further prevent smoke from passing through the fire door, a strip 13 is fixedly connected to one side of the body 2 to which the barrier strip 11 and the doorsill 12 are attached.

Wherein, adhesive tape 13 preferred adopts high temperature resistant rubber material, seals up the crack through this material.

In order to reduce the supporting force of the body 2 to the damper plate 3, a roller 34 is rotatably installed at the lower end of the damper plate 3.

Wherein, gyro wheel 34 rolls on ground, and then conveniently rotates main part 2, and simultaneously, gyro wheel 34 is supporting damper plate 3, and then reduces main part 2 and to damper plate 3's holding power, and gyro wheel 34 still can shield the crack, prevents that the conflagration from taking place the back, and smog gets into through the crack.

In order to enhance the fireproof performance of the wooden fireproof door, the door frame 1, the main body 2 and the damping plate 3 are all coated with paint.

Wherein, the preferred setting of finish is fireproof paint, and this material is prior art, increases wooden fire door's fire stability, fire-resistant integrality, fire-resistant heat-proof quality through fireproof paint.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
