Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a windproof and noise reduction structure for a high-speed elevator landing door. Background Art

[0002] In conventional elevator door systems, there are certain gaps between doors, between doors and door frames, and between doors and sills. During the operation of low-speed elevators, airflow will flow between the shaft and the elevator lobby through these gaps. Since the elevator runs at a low speed, no obvious wind sound and noise will be generated. However, in the case of high-speed elevators, the elevator runs at a high speed, and airflow will rapidly pass through the above gaps, which will generate relatively loud wind sound and noise, bringing an uncomfortable experience to passengers waiting for the elevator, and even affecting the living or office environment of each floor. Therefore, we need to propose a high-speed elevator door windproof and noise reduction structure to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-5 The utility model provides a technical solution: a high-speed elevator landing door windproof and noise reduction structure, comprising a door cover assembly 1, a landing door assembly 2 and a landing door sill 3, the landing door sill 3 is installed at the lower end of the door cover assembly 1, the landing door assembly 2 is located on the landing door sill 3, and a sealing wool strip 6 is installed on one side of the landing door assembly 2, one end of the sealing wool strip 6 is in contact with one side of the door cover assembly 1, that is, one end of the sealing wool strip 6 is slightly in contact with the surface of the door cover assembly 1;

[0024] The floor door assembly 2 includes a left door 21 and a right door 22, and a door rubber strip 4 that can be snapped and opened and closed is provided between the left door 21 and the right door 22. The door rubber strip 4 is used to seal the left door 21 and the right door 22 when the floor door assembly 2 is closed, so as to avoid a gap between the left door 21 and the right door 22, and effectively block the airflow from passing between the left door 21 and the right door 22;

[0025] The door cover assembly 1 is a U-shaped structure consisting of a left door cover 11, a top door cover 13 and a right door cover 12. The top door cover 13 is provided with slots for the left door 21 and the right door 22 to move, so as to improve the stability of the horizontal movement of the left door 21 and the right door 22 when opening the door.

[0026] The sealing wool strips 6 include two top wool strips 62 and two side wool strips 61. The two side wool strips 61 are respectively fixed to the edge of the left door 21 and the right door 22 on the side opposite to the door cover assembly 1. The two top wool strips 62 are respectively fixed to the top of the left door 21 and the right door 22 on the side opposite to the door cover assembly 1. One end of the side wool strips 61 and the top wool strips 62 are both in contact with one side of the door cover assembly 1. The connection between the layer door assembly 2 and the door cover assembly 1 is sealed by the two side wool strips 61 and the two top wool strips 62 to avoid a gap between the layer door assembly 2 and the door cover assembly 1, thereby effectively blocking the airflow from passing between the door cover assembly 1 and the layer door assembly 2.

[0027] The door rubber strip 4 includes a left rubber strip 41 and a right rubber strip 42. One end of the left rubber strip 41 is fixed to one end of the left door 21 close to the right door 22, and one end of the right rubber strip 42 is fixed to one end of the right door 22 close to the left door 21. The other end of the left rubber strip 41 is clamped with the other end of the right rubber strip 42 through a connecting mechanism, so that the left rubber strip 41 and the right rubber strip 42 can be clamped and sealed when the left door 21 and the right door 22 are closed, and can be separated when the left door 21 and the right door 22 are opened, thereby improving the convenience of opening and closing the floor door assembly 2.

[0028] like Figure 5 As shown, one end of the right rubber strip 42 is embedded in the end of the right door 22 close to the left door 21, and one end of the left rubber strip 41 is embedded in the end of the left door 21 close to the right door 22. The connecting mechanism includes a protrusion 43 and a slot 44. The slot 44 is located at the other end of the right rubber strip 42, and the protrusion 43 is located at the other end of the left rubber strip 41. The protrusion 43 and the slot 44 are matched. When the layer door assembly 2 is closed, the protrusion 43 can enter the interior of the slot 44 to seal the left door 21 and the right door 22 to avoid a gap between the left door 21 and the right door 22.

[0029] Baffles 5 are fixed to the lower ends of the left door 21 and the right door 22, and sliding grooves for the baffles 5 on the left door 21 and the right door 22 to slide are provided on the landing door sill 3. Through the mutual coordination between the baffles 5 on the left door 21 and the right door 22 and the landing door sill 3, the gap between the landing door assembly 2 and the sill is avoided, and the airflow is effectively prevented from passing between the landing door sill 3 and the landing door assembly 2.

[0030] Example 2

[0031] The similarities will not be repeated here. The difference from Example 1 is that Figure 6As shown, one end of the left rubber strip 41 is fixed to the side wall of the left door 21 near the end of the right door 22 by bolts, and one end of the right rubber strip 42 is fixed to the side wall of the right door 22 near the end of the left door 21 by bolts. The connecting mechanism includes a protrusion 43 and a slot 44. The protrusion 43 is located at the other end of the right rubber strip 42, and the slot 44 is located at the other end of the left rubber strip 41. The protrusion 43 and the slot 44 are matched. When the layer door assembly 2 is closed, it is convenient for the protrusion 43 to enter the interior of the slot 44 to seal the left door 21 and the right door 22, avoid a gap between the left door 21 and the right door 22, and effectively block the airflow from passing between the left door 21 and the right door 22.

[0032] In summary, after the floor door is closed, the sealing structure composed of the door frame assembly 1, the floor door assembly 2, the floor door sill 3, the door rubber strip 4, the side wool strip 61, the top wool strip 62, and the baffle 5 can effectively block the rapid circulation of air between the hoistway and the elevator lobby when the elevator is running at high speed, thereby reducing wind sound and noise, and improving the riding comfort of passengers to a certain extent.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
