Description

Technical Field

[0001] The utility model relates to the technical field of elevator floor door sill baffles, in particular to an elevator floor door sill shielding plate for preventing dust accumulation. Background Art

[0002] The elevator floor door sill is a horizontal metal component that is close to the ground at openings such as entrances and exits. The main function of the floor door sill is to ensure the normal operation of the door. The elevator floor door sill is an indispensable part of the elevator system. Its design, installation, adjustment and maintenance are directly related to the safety and service life of the elevator.

[0003] However, the elevator door sill is essentially a sunken guide rail. Therefore, when pedestrians pass by the sill during use, it is easy to push dust or other foreign objects into the inside of the sill. Therefore, after long-term use, it is easy to affect the smoothness of the sill. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an elevator floor door sill shielding plate that prevents dust accumulation, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A dust-proof elevator door sill shielding plate comprises an elevator sill and an elevator door, wherein the elevator door is slidingly arranged inside the elevator sill, a receiving cavity is provided at the inner bottom end of the elevator sill, an air bag is arranged inside the receiving cavity, a shielding strip is arranged at the top of the receiving cavity, a pressing wheel is arranged at the bottom end of the elevator door, a pneumatic cylinder is arranged on one side of the elevator sill, and an air guide pipe connected to the air bag is arranged at one end of the pneumatic cylinder.

[0007] Furthermore, there is a gap between the shielding strip and the airbag, and a stabilizing chain plate is provided at the bottom end of the shielding strip.

[0008] Furthermore, the shielding strip is made of a flexible material, and the side wall of the shielding strip fits with the inner wall of the elevator sill.

[0009] Furthermore, the stabilizing chain plate includes a plurality of pressing shaft rollers, both sides of the pressing shaft rollers are provided with connecting plates, and the connecting plates are rotationally connected to the pressing shaft rollers, and the connecting plates connect two adjacent pressing shaft rollers.

[0010] Furthermore, a guide shaft is provided inside the pneumatic cylinder, a pressure piston is slidably provided on the outer surface of the guide shaft, and the outer wall of the pressure piston is in contact with the inner wall of the pneumatic cylinder, and the side wall of the pressure piston is provided with a supporting spring connected to the inner wall of the pneumatic cylinder.

[0011] Furthermore, a mounting shaft is arranged inside the pressing wheel, and fixing plates are arranged on both sides of the mounting shaft, and the two fixing plates are fixedly connected to both sides of the bottom end of the elevator door.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:

[0013] 1. The dust-proof elevator door sill shielding plate has two elevator doors located on both sides of the elevator sill when the elevator doors are open. When the elevator is inside the elevator sill, the elevator doors will compress the airbags to move the air to a position not compressed by the elevator doors. That is, when the elevator doors are opened to both sides along the straight line of the elevator sill, the air inside the airbags will be squeezed to the middle of the airbags, causing the middle of the airbags to swell and bulge, so that the shielding strips arranged on the top of the airbags are lifted up, thereby achieving the purpose of sealing the top of the elevator sill, effectively preventing dust and foreign objects from being brought into the interior of the elevator sill by passengers, and thus effectively protecting the elevator sill.

[0014] 2. An anti-dust elevator door sill shielding plate. When the elevator door is fully closed, the gas inside the airbag will enter the interior of the pneumatic cylinder through the air guide pipe and push the supporting spring, so that a large amount of air will enter the interior of the pneumatic cylinder to achieve the effect of protecting the airbag. When the elevator door is opened, the air pressure inside the airbag decreases. At this time, the supporting spring will push the air into the airbag, causing the airbag to expand rapidly and lift up the shielding strip, thereby achieving the purpose of increasing the closing speed of the elevator sill.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 6 The utility model discloses an anti-dust accumulation elevator door sill shielding plate, comprising an elevator sill 1 and an elevator door 2, the elevator door 2 being slidably arranged inside the elevator sill 1, a receiving cavity 3 being provided at the inner bottom end of the elevator sill 1, an air bag 4 being provided inside the receiving cavity 3, a shielding strip 5 being provided at the top of the receiving cavity 3, a pressing wheel 6 being provided at the bottom end of the elevator door 2, a pneumatic cylinder 7 being provided at one side of the elevator sill 1, and an air guide pipe 8 connected to the air bag 4 being provided at one end of the pneumatic cylinder 7.

[0026] In this embodiment, the accommodating chamber 3 is provided for installing the airbag 4, and the air guide tube 8 and the pneumatic cylinder 7 are provided for storing air to avoid the problem that the airbag 4 is compressed and causes the airbag 4 to burst. The friction force of the elevator door 2 on the shielding strip 5 is reduced by the provision of the pressing wheel 6, so as to achieve the effect of increasing the service life of the shielding strip 5.

[0027] When the elevator doors 2 are in a closed state, the two elevator doors 2 are in contact with each other, shielding the corresponding position of the elevator sill 1 and the elevator door. At this time, passengers cannot enter the elevator, so dust will not follow the passengers into the elevator.

[0028] When the elevator doors 2 are opened, the two elevator doors 2 are respectively located on both sides of the elevator sill 1. When the elevator is inside the elevator sill 1, the elevator doors 2 will compress the airbag 4, causing the air to move to a position not compressed by the elevator doors 2. That is, when the elevator doors 2 are opened to both sides along the straight line direction of the elevator sill 1, the air inside the airbag 4 will be squeezed to the middle of the airbag 4, causing the middle of the airbag 4 to swell and bulge, so that the shielding strip 5 set at the top of the airbag 4 is lifted up, thereby achieving the purpose of sealing the top of the elevator sill 1. At this time, the position in the middle of the elevator sill 1 that is not blocked by the elevator doors 2 will be blocked by the shielding strip 5. Figure 1 As shown, dust and foreign objects can be effectively prevented from being brought into the elevator sill 1 by passengers, thereby effectively protecting the elevator sill 1.

[0029] In a further preferred embodiment of the present invention, Figure 1-6 As shown, there is a gap between the shielding strip 5 and the airbag 4 , and a stabilizing chain plate 9 is provided at the bottom end of the shielding strip 5 .

[0030] In this embodiment, when the elevator door 2 and the pressing wheel 6 compress the airbag 4 through the shielding strip 5, the airbag 4 sinks more evenly by stabilizing the chain plate 9, so as to avoid the problem that only the position of the airbag 4 corresponding to the position of the pressing wheel 6 sinks, while the adjacent position bulges, thereby achieving the purpose of increasing the service life of the airbag 4.

[0031] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the shielding strip 5 is made of a flexible material, and the side wall of the shielding strip 5 fits with the inner wall of the elevator sill 1 .

[0032] In this embodiment, since the shielding strip 5 is made of a flexible and elastic material, when the elevator door 2 is opened or closed, the shielding strip 5 can be effectively lifted up by the airbag 4 and bent at a position close to the elevator door 2 to increase the shielding rate of the elevator sill 1. Figure 6 shown.

[0033] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the stabilizing chain plate 9 includes a plurality of pressing shaft rollers 91 , and connecting pieces 92 are provided on both sides of the pressing shaft rollers 91 , and the connecting pieces 92 are rotationally connected to the pressing shaft rollers 91 , and the connecting pieces 92 connect two adjacent pressing shaft rollers 91 .

[0034] In this embodiment, the setting of two pressing shaft rollers 91 connected by a connecting piece 92 can effectively make the stabilizing chain plate 9 form a movable chain, and the connecting piece 92 is made of elastic material, so that the stabilizing chain plate 9 can expand and contract following the ups and downs of the airbag 4, so as to achieve the effect of making the stabilizing chain plate 9 always fit the airbag 4. Since the lengths of the two ends of the pressing shaft roller 91 are equal to the width of the airbag 4, when the pressing shaft roller 91 is compressed by the elevator door 2, the airbag 4 can be completely pressed down, so that the gas inside the airbag 4 is moved to a position that is not compressed by the elevator door 2, thereby facilitating the transfer of air, thereby preventing the problem of bulging of the airbag 4 due to incomplete air movement.

[0035] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a guide shaft 71 is provided inside the pneumatic cylinder 7, a pressure piston 72 is slidably provided on the outer surface of the guide shaft 71, and the outer wall of the pressure piston 72 is in contact with the inner wall of the pneumatic cylinder 7, and the side wall of the pressure piston 72 is provided with a supporting spring 73 connected to the inner wall of the pneumatic cylinder 7.

[0036] In this embodiment, the guide shaft 71 is provided for installing the pressure piston 72. When the air pressure inside the airbag 4 is too high, that is, when the elevator door 2 is completely closed, the gas inside the airbag 4 will enter the interior of the pneumatic cylinder 7 through the air guide tube 8 and push the support spring 73, so that a large amount of air enters the interior of the pneumatic cylinder 7 to achieve the effect of protecting the airbag 4. When the elevator door 2 is opened, the air pressure inside the airbag 4 becomes smaller. At this time, the support spring 73 will push the air into the interior of the airbag 4, causing the airbag 4 to expand, so as to lift up the shielding strip 5, thereby closing the elevator sill 1.

[0037] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a mounting shaft 61 is disposed inside the pressing wheel 6 , and fixing plates 62 are disposed on both sides of the mounting shaft 61 . The two fixing plates 62 are fixedly connected to both sides of the bottom end of the elevator door 2 .

[0038] In this embodiment, the pressing wheel 6 is fixed by installing the shaft 61 and the fixing plate 62, so that the pressing wheel 6 is installed at both ends of the bottom of the elevator door 2. When the elevator door 2 moves, the airbag 4 is pressed by the pressing wheel 6 to reduce the friction of the elevator door 2 on the shielding strip 5, thereby achieving the purpose of increasing the service life of the shielding strip 5.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
