Description

Technical Field

[0001] The invention relates to a flip-type movable threshold impact-resistant protective door, belonging to the technical field of protective doors. Background Art

[0002] A protective door is a door that can withstand various shock waves or heavy object collisions, and is generally made of steel. The threshold mechanism of a protective door is divided into a fixed threshold, a movable threshold, and a drop-type threshold. Fixed thresholds are relatively cheap, but are inconvenient for people and vehicles to enter and exit; movable thresholds can be installed when needed to provide protection and sealing functions. For existing movable threshold protective doors, the movable threshold is easily lost or damaged when placed alone, and is mostly needed for emergencies. The movable threshold is inconvenient to take and install, which can lead to unnecessary accidents. In addition, the function of the movable threshold of existing protective doors mostly only considers the sealing function, and does not consider the function of transmitting shock waves or heavy object collisions. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a flip-type movable threshold anti-impact protective door in response to the above-mentioned prior art. It adopts a flip-type movable threshold. When the door leaf is opened, the movable threshold can be flipped down into the pit to keep the door leaf passage unobstructed; when the door leaf is closed, the movable threshold can be flipped upward to offset the door leaf, thereby ensuring the impact resistance of the door leaf.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: a flip-type movable threshold anti-impact protective door, which includes a wall, a door opening is opened on the wall, a door leaf is arranged at the position of the door opening, the door leaf is hinged to the wall, a pit is arranged at the rear side of the door opening, and a flip-type movable threshold is arranged in the pit. When the door leaf is opened, the flip-type movable threshold flips down to the pit; when the door leaf is closed, the flip-type movable threshold flips up to abut against the door leaf.

[0005] Optionally, there are two door leaves, which are arranged opposite to each other on the left and right.

[0006] Optionally, the door leaf is hinged to the wall via a door leaf rotation mechanism.

[0007] Optionally, the flip-up movable threshold includes a plurality of rotating shaft seats arranged at intervals on the left and right, the rotating shaft seats are fixedly set in a pit, a rotating shaft is installed between the plurality of rotating shaft seats, a threshold body is set on the rotating shaft, the rear part of the threshold body is hinged to the rotating shaft seat through the rotating shaft, an electric push rod is set on one side above the threshold body, and the lower end of the electric push rod is connected to the front part of the threshold body.

[0008] Optionally, the threshold body includes a top plate, a bottom plate, a front baffle and a rear baffle, and a support and limiting plate is provided at the front of the bottom plate.

[0009] Optionally, an intermediate baffle is provided between the top plate and the bottom plate.

[0010] Optionally, the threshold body is provided with a plurality of latch openings at intervals on the front side of the middle baffle.

[0011] Optionally, when the door leaf is opened, the threshold body flips down until the support limit plate on the bottom plate abuts against the bottom surface of the pit, and at this time the top plate of the threshold body is flush with the top surface of the pit; when the door leaf is closed, the threshold body flips up until the rear baffle abuts against the limit baffle, and at this time the front baffle of the threshold body abuts against the door leaf.

[0012] Optionally, a shaft support plate is provided on the left and right sides of the shaft seat.

[0013] Optionally, a limit baffle is provided at the rear side of the pit, and the limit baffle is located behind the threshold body.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The present invention discloses a flip-type movable threshold anti-impact protective door, which adopts a flip-type movable threshold. When the door leaf is opened, the movable threshold can be flipped down into a ground pit, so that the door leaf passage remains unobstructed; when the door leaf is closed, the movable threshold can be flipped up to abut against the door leaf, thereby ensuring the anti-impact ability of the door leaf.

[0048] The present invention is further described in detail below with reference to the accompanying drawings.

[0049] See also Figures 1 to 8The present invention relates to a flip-type movable threshold impact-resistant protective door, which comprises a wall 1, a door opening 2 is formed on the wall 1, a door leaf 3 is arranged at the position of the door opening 2, the door leaf 3 is hinged to the wall 1, a pit 4 is arranged at the rear side of the door opening 2, a flip-type movable threshold 5 is arranged in the pit 4, when the door leaf 2 is opened, the flip-type movable threshold 5 flips down to the pit 4 and is flush with the ground; when the door leaf 2 is closed, the flip-type movable threshold 5 flips up to abut against the door leaf 2;

[0050] There are two door leaves 2, and the two door leaves 2 are arranged opposite to each other on the left and right;

[0051] The flip-up movable threshold 5 includes a plurality of rotating shaft seats 51 arranged at intervals on the left and right, the rotating shaft seats 51 are fixedly arranged in the pit 4, a rotating shaft 52 is installed between the plurality of rotating shaft seats 51, a threshold body 53 is arranged on the rotating shaft 52, the rear part of the threshold body 53 is hinged to the rotating shaft seat 51 through the rotating shaft 52, an electric push rod support 54 is arranged on one side above the threshold body 53, the electric push rod support 54 is fixedly arranged on the wall 1, an electric push rod 55 is hingedly arranged on the electric push rod support 54, and the lower end of the electric push rod 55 is connected to the front part of the threshold body 53;

A support limit plate 535 is provided at the front of the bottom plate 532. A limit baffle plate 10 is provided at the rear side of the pit 4. The limit baffle plate 10 is located behind the threshold body 51.

[0053] An intermediate baffle 536 is provided between the top plate 531 and the bottom plate 532;

[0054] When the door leaf 2 is opened, the threshold body 51 flips down until the support limit plate 535 on the bottom plate 532 abuts against the bottom surface of the pit 4. At this time, the top plate of the threshold body 51 is flush with the ground, and the pit can be filled, thereby ensuring smooth passage at the door opening; when the door leaf 2 is closed, the threshold body 51 flips up until the rear baffle 534 abuts against the limit baffle 10.

Since there may be a certain installation gap between the threshold body and the limit baffle, by installing the rotating shaft support plates at a suitable distance on the left and right sides of the rotating shaft seat, under the limiting effect of the rotating shaft support plates, when the threshold body is impacted by the door leaf, the rotating shaft is allowed to bend backward to a certain extent, thereby compensating for the matching gap between the threshold body and the limit baffle, ensuring that the threshold body and the limit baffle are closely matched, and at the same time, the bending of the rotating shaft within a reasonable range does not affect the normal lifting or falling of the threshold body;

[0056] The threshold body 1 is provided with a plurality of latch openings 57 at intervals in front of the middle baffle 536;

[0057] The door leaf 2 is hinged to the wall 1 via a door leaf rotating mechanism 6;
