Description

Technical Field

[0001] The utility model relates to the technical field of elevator protection doors, in particular to an automatically locked magnetic adsorption type anti-deformation elevator protection door. Background Technique

[0002] The anti-deformation elevator protection door is a door that can resist various shock waves or heavy object impacts, and is generally made of steel materials.

[0003] For example, a magnetic adsorption type anti-deformation construction elevator protection door for construction sites with the authorization announcement number of "CN210888575U", by setting a female magnetic adsorption door bumper and a male magnetic adsorption door bumper, etc., makes the magnetic adsorption type anti-deformation construction elevator protection door for construction sites not easily damaged and unable to be closed, effectively preventing the occurrence of object hitting or falling from a height accidents. By setting a first round tube and a second round tube, etc., makes the magnetic adsorption type anti-deformation construction elevator protection door for construction sites effectively prevent the double doors from being unable to be closed when misaligned. However, during the use of the elevator protection door, only the upper crossbeam is strengthened against collision, but the strength of the elevator protection door itself has not changed. When the elevator protection door is impacted, it will deform and contact the crossbeam, only making the deformation of the elevator protection door reach the limit, rather than achieving anti-deformation itself, reducing the protection effect of the elevator protection door and shortening the service life of the elevator protection door.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below with reference to the accompanying drawings:

[0020] Embodiment 1:

[0021] Please refer to Figures 1-5 : In this embodiment, an automatically locked magnetic anti-deformation elevator protection door includes a frame 1 and an elevator protection door 4. The rear inner wall of the frame 1 is rotatably connected to the outer wall of the elevator protection door 4. The elevator protection door 4 rotates through a pin shaft at the rear of the inner wall of the frame 1 under force. A first magnet 5 is fixedly connected to the top of the front surface of the elevator protection door 4. The first magnet 5 is a positive pole. A second magnet 6 is adsorbed and connected to the front surface of the first magnet 5. The second magnet 6 is a negative pole. The top of the second magnet 6 is fixedly connected to the top of the inner wall of the frame 1. A reinforcement structure 2 is connected to the front surface of the elevator protection door 4. A square plate 7 is fixedly connected to the lower part of the front surface of the elevator protection door 4. A locking structure 3 is connected to the inner wall of the square plate 7.

[0022] The reinforcement structure 2 includes a vertical plate 201 and a straight plate 202. The rear end surface of the vertical plate 201 is attached to the front surface of the elevator protection door 4. The inner side of the vertical plate 201 is fixedly connected to the end of the straight plate 202. The vertical plate 201 and the straight plate 202 reinforce the elevator protection door 4 through their own steel plate materials. Curved plates 203 are fixedly connected to the upper and lower sides of the vertical plate 201 respectively. A bolt 204 is threadedly connected to the inner wall of the curved plate 203. The rear end surfaces of the curved plate 203 and the straight plate 202 are both attached to the front surface of the elevator protection door 4. The bolt 204 fixes the curved plate 203 and the elevator protection door 4. The rear outer wall of the bolt 204 is threadedly connected to the round opening on the front surface of the elevator protection door 4. A handle 8 is fixedly connected to the front surface of the inner vertical plate 201;

[0023] Through the curved plates 203 on the upper and lower sides of the vertical plate 201 in the reinforcement structure 2 being located in front of the round opening on the front surface of the elevator protection door 4, and then the bolt 204 is threadedly connected from the right front to the rear through the curved plate 203 and the round opening on the front surface of the elevator protection door 4, the vertical plate 201 and the straight plate 202 are completed. The vertical plate 201 and the straight plate 202 play a reinforcement role in front of the elevator protection door 4, preventing the elevator protection door 4 from being damaged by impact, improving the protection effect of the elevator protection door, and ensuring the service life of the elevator protection door.

[0024] The locking structure 3 includes a vertical rod 301 and a curved block 302. The outer wall of the vertical rod 301 is inserted into the inner wall of the square plate 7. The vertical rod 301 moves up and down through the inner wall of the square plate 7 under force. The bottom of the vertical rod 301 is fixedly connected to the top of the curved block 302. A spring 303 is sleeved on the outer wall of the vertical rod 301. The upper and lower ends of the spring 303 are respectively fixedly connected to the bottom of the square plate 7 and the top of the curved block 302. After the curved block 302 moves upward under force, it rebounds through the elastic force of the spring 303. A spherical ball 304 is fixedly connected to the top of the vertical rod 301. The spherical ball 304 facilitates pulling the vertical rod 301. The bottom of the outer wall of the curved block 302 is inserted into the notch at the bottom of the inner wall of the frame 1.

[0025] Working principle:

[0026] Installation of elevator protection door:

[0027] Weld the connection between the door frame 1 and the elevator car to complete the fixation. Then, fit the vertical plate 201 to the front of the elevator protection door 4. At this time, the curved plates 203 on both the upper and lower sides of the vertical plate 201 are in front of the round openings on the front of the elevator protection door 4. Then, the bolt 204 is threaded through the curved plate 203 from the right front to the back and is threadedly connected to the round opening on the front of the elevator protection door 4 to complete the vertical plate 201 and the straight plate 202. The vertical plate 201 and the straight plate 202 play a reinforcement role in front of the elevator protection door 4 to prevent the elevator protection door 4 from being damaged by impact.

[0028] Use of elevator protection door:

[0029] Pull the handle 8. The handle 8 drives the elevator protection door 4 to rotate forward. At the same time, cooperate with the square plate 7 to drive the locking structure 3 to move forward, so that the front surface of the curved block 302 fits under the front frame 1. Due to the inclined surface of the curved block 302 itself and the insertion fit between the vertical rod 301 and the square plate 7, the curved block 302 is forced to move upward, and at the same time, the spring 303 is compressed. When the bottom of the curved block 302 moves to the bottom of the inner wall of the frame 1, the spring 303 provides a return force to make the curved block 302 move downward. The bottom of the outer wall of the curved block 302 will be inserted into the notch at the bottom of the inner wall of the frame 1 to achieve automatic locking. At this time, the first magnet 5 above the front of the elevator protection door 4 and the second magnet 6 at the bottom of the inner wall of the frame 1 are adsorbed and connected.

[0030] Embodiment 2:

[0031] Please refer to Figures 1-5 : In this embodiment, an automatically locking magnetic adsorption type anti-deformation elevator protection door further includes a bottom plate 9. The inner sides of the two bottom plates 9 are fixedly connected to the front and rear bottom sides of the frame 1 respectively.

[0032] Working principle:

[0033] The curved plate 9 will form inclined surfaces at the front and rear bottom sides of the frame 1. The curved plate 9 is convenient for the vehicle body to pass through and avoids the vehicle body being carried when passing through the frame 1.

[0034] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
