Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment, and specifically to a micro-gap structure of a sill for an elevator. Background Art

[0002] In existing lift elevators, there is often a large gap between the car door and the hall door. The national standard stipulates that this gap is allowed to exist, and the qualified standard for the gap is within 30 mm. The existence of the gap is necessary. When getting on and off passengers or transporting goods, the physical weight of the passengers or goods in the car will change, and the car will vibrate or shake. This gap can prevent the car from colliding with the hall door sill and causing damage to the car and the shaft. However, the existence of this gap creates certain safety hazards. Even if the gap meets the standards, it will create some unexpected safety hazards. For example, women's high heels can easily get stuck in the gap, and small objects such as keys will fall into the shaft through the gap, causing the risk of falling objects from high altitude. Not only that, the existence of the gap also affects the aesthetics of the elevator and increases the fear of taking the elevator.

[0003] At present, the door opening and closing mode of common elevators on the market is that the door opening knife fixed on the car door hanging plate clamps the hall door lock roller fixed on the hall door, thereby driving the door hook lock to open. In this mode, the elevator door knife must extend beyond the car sill, and the hall door lock roller must also extend beyond the hall door sill. In addition to the necessary movement gap, there must be a certain distance between the car sill and the hall door sill. This distance shall not exceed 35 mm in the national standard. At present, elevators on the market generally control this distance within a distance of 25 to 35 mm. The existence of this distance often causes trolleys, wheelchair rollers, high heels, etc. to be stuck, and small items to fall into the elevator shaft through this movement gap. Accidents such as. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-4 , an embodiment provided by the present invention:

[0021] A micro-gap structure for an elevator sill comprises a bottom plate 1, a first connecting rod 2 is connected to the outer surface of the bottom plate 1, a second connecting rod 3 is connected to the outer surface of the bottom plate 1, a left baffle 8 is connected to the end of the first connecting rod 2 away from the bottom plate 1, the second connecting rod 3 is connected to the inner surface of the left baffle 8, a first linkage device 5 is connected to the outer surface of the left baffle 8, and a roller 4 is connected to the top end of the first linkage device 5.

[0022] The outer surface of the first linkage device 5 is connected with a spring 6, and the end of the spring 6 away from the first linkage device 5 is connected with the second linkage device 7. The top of the bottom plate 1 is connected with a first connecting block 10, and the top of the first connecting block 10 is connected with a right baffle 9. An insert block 11 is inserted inside the first connecting block 10, and both ends of the insert block 11 are connected with limiting wheels 12. The number of limiting wheels 12 is set to four groups, and the four groups of limiting wheels 12 are respectively connected to the two ends of the insert block 11. The movement of the insert block 11 can be limited by the limiting wheels 12 to prevent the insert block 11 from moving too far or misaligned in direction. The inner side of the insert block 11 is connected with a second connecting block 15, and the end of the second connecting block 15 is connected to the limiting block 13. The inner surface of the second connecting block 15 is movably connected with a gear 14.

[0023] Furthermore: a mounting hole is provided at one end of the left baffle 8, and the mounting hole is connected to the first linkage device 5 through a hinge. By providing a mounting hole at one end of the left baffle 8, the first linkage device 5 can be connected to the left baffle 8, thereby improving the firmness and stability of the equipment.

[0024] Furthermore: the first connecting block 10 and the base plate 1 are slidably connected, the plug block 11 is rectangular in shape, the limiting wheel 12 and the inner wall of the first connecting block 10 are rollingly connected, and the first connecting block 10 can be opened and closed by slidingly connecting the first connecting block 10 and the base plate 1. Since the right baffle 9 is connected to the first connecting block 10, the right baffle 9 will also be driven to move. By setting the plug block 11 to a rectangle, the first connecting block 10 can be limited and fixed, and the limiting wheel 12 and the inner wall of the first connecting block 10 can be rolled to limit the moving direction of the plug block 11 to prevent deviation in the movement of the plug block 11.

[0025] Furthermore: the number of the plug blocks 11 is set to two groups, and the two groups of plug blocks 11 are respectively connected to the inside of the first connecting block 10, and the plug blocks 11 and the second connecting block 15 are perpendicular to each other. By setting two groups of plug blocks 11, the two ends of the first connecting block 10 can be plugged and fixed, and the plug blocks 11 and the second connecting block 15 are made perpendicular to each other, so that the second connecting block 15 can drive the plug blocks 11 to move outward.

[0026] Furthermore, the gear 14 and the second connecting block 15 are connected in rotation, and a tooth block is provided on the inner surface of the second connecting block 15, and the tooth block and the gear 14 are meshed. By setting the gear 14 and the second connecting block 15 to rotate, the gear 14 drives the second connecting block 15 to move outward, and the tooth block on the inner surface of the second connecting block 15 is meshed with the gear 14 to achieve the purpose of movement.

[0027] Furthermore: the number of second connecting blocks 15 is set to two groups, and the two groups of second connecting blocks 15 are respectively connected to the left and right ends of the gear 14. Through the two groups of second connecting blocks 15, when the gear 14 is rotated, the plug 11 can be driven to move outward, thereby improving the convenience of using the equipment.

[0028] Working principle: First, we need to connect the equipment to the required position. When the car door is opened, the first linkage device 5 is bounced up by the spring 6, and at the same time drives the left baffle 8 to move horizontally to fill the gap. When the car door is closed, the first linkage device 5 is pushed by the car door to push the left baffle 8 to the other side, making room for the hall door wheel to avoid malfunction caused by the left baffle 8 not being retracted and touching the door wheel when the elevator is running.

[0029] Then we can connect the right baffle 9 and the first connecting block 10, and by rotating the gear 14, the gear 14 drives the second connecting block 15 to move outward. Since the gear 14 and the second connecting block 15 are meshingly connected, the rotation of the gear 14 will drive the second connecting block 15 to move, and the second connecting block 15 will push the plug-in block 11 to extend outward, and the plug-in block 11 extends outward and connects with the bottom plate 1, thereby completing the installation of the right baffle 9.

[0030] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
