Description

Technical Field

[0001] The utility model relates to the technical field of elevator door covers, in particular to an elevator door cover structure. Background Art

[0002] Elevator door covers are a kind of decorative material installed on elevator doors. They are mainly used to protect the edges and corners of elevator doors and improve the aesthetics of elevator doors. Functionally, elevator door covers fix elevator doors to prevent accidental falling off when elevator doors are opened, thereby ensuring passenger safety. In addition, they can also improve the stability and sealing of elevator doors, effectively isolating gases, dust, noise, etc. inside and outside the car, ensuring a comfortable riding experience for passengers.

[0003] When the elevator door frame structure is in use, it is easy to be hit by external force or foreign objects, which will cause damage to the door frame and affect the overall aesthetics of the door frame. In serious cases, the door frame needs to be replaced as a whole, which is time-consuming and labor-intensive, causing economic losses. Based on these problems, Chinese patent CN217458403U discloses an elevator door frame structure, which can increase the overall aesthetics of the elevator door frame by adding antique copper stainless steel plates and light strips. The antique copper stainless steel plates are corrosion-resistant and have a long service life. The light strips can indicate at night, increasing the overall practicality of the door frame structure. By setting up an anti-collision mechanism, when there is an external object collision, the protective pad can be protected by the protective strip and the reinforcing ribs. At the same time, the damping buffer shrinks to absorb the impact force, thereby achieving the advantage of increasing the anti-collision performance of the door frame.

[0004] There are gaps for buffering between the protective pad, anti-collision mechanism and light strip in the elevator door frame, so dust and water vapor in the outside air can easily enter and accumulate in the gaps. If they are not removed in time, it will not only affect the buffering effect of the anti-collision mechanism, but also reduce the service life of the damping buffer and the buffer mechanism. Since the disassembly and assembly steps between the anti-collision mechanism and the protective pad are relatively complicated, it will also bring a lot of inconvenience to the cleaning staff.

The present invention provides the following embodiments.

[0036] Reference Figure 1-8The utility model provides an embodiment: an elevator door frame structure, including a top plate 1, an elevator door 2 is installed at the rear end of the top plate 1, first stainless steel plate frames 3 are welded at both ends of the bottom of the top plate 1, the front end of the first stainless steel plate frame 3 is fixedly connected with a sliding frame 4, the internal cross-sectional size of the sliding frame 4 is larger than the internal cross-sectional size of the first stainless steel plate frame 3, the opposite surface of the first stainless steel plate frame 3 is fixedly connected with an arc wall panel 5, the rear end of the arc wall panel 5 is fixedly connected with a second stainless steel plate frame 6, the rear end of the inner wall of the first stainless steel plate frame 3 is fixedly connected with a first wall panel 7, by arranging the first wall panel 7, the stability of the first stainless steel plate frame 3 can be improved, one end of the inner wall of the second stainless steel plate frame 6 is fixedly connected with a second wall panel 8, by arranging the second wall panel 8, the stability of the second stainless steel plate frame 6 can be improved.

[0037] Both sides of the front end of the first wall panel 7 and both ends of the opposite surfaces of the two groups of second wall panels 8 are fixedly connected with pads 9, and the front ends of the pads 9 are fixedly connected with inserts 10. The outer walls of the inserts 10 are sleeved with sleeves 11. Long-axis bolts 12 pass through the center of the front end of the inserts 10. The inner wall of the sleeve 11 is threaded. The threaded portion of the outer wall of the long-axis bolt 12 can be threadedly connected with the inner wall of the insert 10. The sleeve 11 can be fixed to the outer wall of the insert 10 by the long-axis bolt 12.

By setting the ventilation holes 24, when the first protective plate 16 and the second protective plate 22 slide back and forth, the gas will pass through the ventilation holes 24, so as to balance the air pressure on both sides of the first protective plate 16 and the second protective plate 22. By setting the second dust-proof ventilation net 25, dust in the outside air can be prevented from entering the first stainless steel plate frame 3 or the second stainless steel plate frame 6. The top and bottom ends of the second protective plate 22 are penetrated by the second shell 26, and the first shell 19 and the second shell 26 are provided with a cavity that runs through the front and back. The size of one end of the inner wall of the cavity becomes smaller, and a thread is provided at the other end of the inner wall. One end of the inner wall of the first shell 19 and the second shell 26 are both slidably connected to the outer wall of the sleeve 11. The sleeve 11 can limit the range of movement of the first shell 19 and the second shell 26, and can also fix the first shell 19 and the second shell 26. When the sleeve 11 is removed from the insert 10, the first protective plate 16 of the outer wall of the first shell 19 can be removed from the first stainless steel plate frame 3, and the second protective plate 22 of the outer wall of the second shell 26 can be removed from the second stainless steel plate frame 6. At this time, the staff can clean the inside of the first stainless steel plate frame 3 or the second stainless steel plate frame 6.

[0041] The other ends of the inner walls of the first shell 19 and the second shell 26 are both threadedly connected with a hollow cover 20. By setting the hollow cover 20, the sleeve 11 and the long-axis bolt 12 can be shielded and protected. The inner walls of the hollow cover 20 are fixedly connected with a third dustproof ventilation net 21. The raised portions of the arc-shaped wall panels 5 are fixedly connected with arc-shaped protective plates 27. A light bar 28 is installed in the arc-shaped protective plates 27. A groove is provided in the arc-shaped protective plates 27. The light bar 28 is installed in the inner groove of the arc-shaped protective plates 27. The raised portions of the arc-shaped protective plates 27 are bonded with a first sticker 29. The first sticker 29 is provided with a first square groove 30 that runs through the front and back. By setting The first square groove 30 is arranged to expose the light strip 28, and the front end of the first protective plate 16 and the opposite surfaces of the two groups of second protective plates 22 are adhered with the second sticker 31. By arranging the first sticker 29 and the second sticker 31, the aesthetics of the elevator door frame can be improved. The second sticker 31 has second square grooves 32 running through the front and back at both ends, and the inner walls of the second square grooves 32 are sleeved with one end of the outer wall of the hollow cover 20. The other two ends of the second sticker 31 have third square grooves 33 running through the front and back, and the third square grooves 33 are arranged at the front ends of the ventilation frame 14 and the ventilation hole 24, so that the ventilation frame 14 and the ventilation hole 24 are exposed.
