Description

Technical Field

[0001] The present application relates to the field of elevator maintenance technology, and specifically to a warning sign for elevator maintenance. Background Art

[0002] An elevator is a type of transportation equipment that carries pedestrians or goods vertically. It is widely used in high-rise residential and office buildings to facilitate the movement of people and goods up and down floors. When an elevator is in use, it is often subject to regular maintenance and inspection to prevent sudden emergency or high-risk failures during use. When the elevator is inspected and maintained, a warning panel is often placed at the elevator door to warn people not to enter, in order to prevent others from getting injured by breaking into a faulty elevator.

[0003] For example, the Chinese utility model patent with publication number "CN219891834U" discloses a warning sign with good warning effect for elevator maintenance, which is achieved by vertically placing upright pole one and upright pole two, sleeve a connecting piece on the surface of upright pole two, and then pulling the spring rod to enable the connecting piece to move downward until the spring rod can be inserted into the fixing groove to fix the connecting piece, and the threaded rod end of the cross rod is inserted from the through hole until the threaded rod is screwed into the interior of upright pole one, thereby fixing upright pole one and upright pole two through two cross rods to form a frame, and then sleeve the other side on the connecting piece in the same way to form an opening and closing type elevator maintenance warning sign, which can increase the opening and closing angle by rotating the hinge according to the size of the elevator being maintained, thereby increasing the warning range and achieving a good warning effect, and it can be disassembled after the maintenance is completed without taking up a lot of storage space, and is easy to carry.

[0004] However, in the above patent, although the structure of the prior art can provide warnings to passers-by during elevator maintenance, when such devices are actually used, the width of the device is combined by splicing the frames. After installation, it occupies a large space in the corridor where the elevator is installed, which is not convenient for pedestrians to pass through, and it is not convenient for staff to carry the device with them for convenient use.

[0033] Reference Figure 1 and Figure 2 In one aspect of the present application, a fixed suction cup 410 is fixedly installed at the output end of the telescopic rod, and multiple groups of telescopic rods are fixedly installed on the outer surface of the pulling and unfolding shaft 3, and multiple groups of damping hinge seats 106 hingedly connected to the telescopic rods are arranged on the surface of the winding chamber 1.

[0034] The telescopic rod includes a connecting sleeve rod 401 and a connecting rod 402 which are sleeved and connected. The surface of the connecting sleeve rod 401 is threadedly connected to a locking bolt 403 for fixing the connecting rod 402 against abutment. When the device is in use, the device can be unfolded and fixed at the elevator entrance for placement and use by adsorbing the fixed suction cup 410 at the telescopic end of the telescopic rod to the planes on both sides of the elevator entrance. The use length of the connecting rod 402 can be adjusted by adjusting the tightness of the locking bolt 403, thereby adjusting the distance between the device and the walls on both sides of the elevator entrance.

[0035] Reference Figure 2 and Figure 3In one aspect of the present application, a handle 105 is fixedly mounted on one side of the surface of the shell 101, and a reflective strip is provided on the surface of the warning banner 2. When the device is in use, by pulling the handle 105, the staff can conveniently carry the rolled-up device by hand, and by providing the reflective strip on the surface of the warning banner 2, the warning banner 2 can be made more conspicuous, thereby providing warnings to pedestrians.

[0036] Reference Figure 1 and Figure 4 In one aspect of the present application, one end of the winding shaft 102 is rotatably connected to the shell 101 through a bearing seat, and the other end of the winding shaft 102 penetrates the shell 101, and a rotating disk 103 is fixedly installed on one end of the winding shaft 102 that passes through the shell 101.

[0037] A resisting fixing member 110 for resisting and fixing the winding shaft 102 is disposed on one side of the housing 101 . The resisting fixing member 110 includes a pull-out rod 111 penetratingly connected to one side of the housing 101 . A limit plate is fixedly installed on one end of the pull-out rod 111 passing through the housing 101 .

[0038] The pull-out rod 111 penetrates into one end of the shell 101 and is fixedly installed with a resistance plate 113, and the pull-out rod 111 is sleeved with a limit spring 112 at one end thereof that is close to the resistance plate 113. When the device is in use, the resistance limit of the resistance plate 113 on the winding shaft 102 can be released by pulling the limit plate outside the resistance fixing member 110 outward, and the warning banner 2 can be wound onto the winding shaft 102 or unfolded for use by rotating the rotating disk 103 or pulling the pull-out unfolding shaft 3 outward, and after unfolding or winding up the warning banner 2, by releasing the pulling of the limit plate outward, the resistance plate 113 will, under the action of the elastic force of the limit spring 112, come into contact and squeeze with the winding shaft 102 and the warning banner 2 wound on the surface, so as to avoid accidental retraction and release of the device when it is unfolded for use or stored and carried.

[0039] Working principle: When using the elevator maintenance warning sign, the device should first be carried to the desired location by holding the handle 105, and according to the horizontal size of the elevator entrance, the warning banner rolled up in the winding chamber 1 is unfolded to a suitable size by pulling the resistance fixing member 110 on one side of the winding chamber 1, and then pulling the pull-out unfolding shaft 3 outward. In this process, by releasing the pull on the resistance fixing member 110, the resistance plate 113 of the resistance fixing member 110 will, under the elastic force of the limit spring 112, resist and squeeze the winding shaft 102 and the warning banner 2 rolled up on the surface, so as to prevent the warning banner from being deformed. 2 In the event of accidental retraction and release, during this process, by setting multiple sets of fixing mechanisms 4 outside the reeling chamber 1 and the pull-out and unfolding shaft 3, that is, in the fixing mechanism 4, the fixing suction cup 410 is fixed to the planes on both sides of the elevator entrance by adsorption, the device can be conveniently placed and fixed at the elevator entrance to provide a warning to passers-by, and after the device is used, by pulling the abutting fixing member 110 outwards and then rotating the rotating disk 103 at one end of the reeling chamber 1, the warning banner 2 can be rolled into the reeling chamber 1, and the pull-out and unfolding shaft 3 can be released to make the warning banner 2 rolled and fixed in the reeling chamber 1, and the pull-out and unfolding shaft 3 can be fixed outside the reeling chamber 1.
