Description

Technical Field

[0001] This utility model relates to the field of elevator door sealing technology, and in particular to a high-sealing soft and hard door sealing strip for elevator landing doors. Background Technology

[0002] Door seals are an important component of elevators. They are symmetrically installed at the ends of the left and right elevator doors. When the left and right elevator doors are closed, the door seals on the left and right sides fit together, serving functions such as sealing, anti-collision, light blocking, and decoration.

[0003] In existing technologies, elevator door seals generally use a combination of metal frame and rubber, such as aluminum alloy frame or stainless steel frame, which is costly and prone to permanent deformation under external force, affecting service life.

[0004] An existing patent (publication number: CN219448986U) discloses a soft and hard door seal for elevator landing doors. This utility model uses a buffer element set on the seal body to provide a good buffering effect. With the cooperation of the compression absorption groove, when the buffer element is subjected to a large impact force, the linkage push block can push the edges of the buffer element on both sides of the compression absorption groove to expand. Under the action of the buffer element itself, the linkage push block can be reset, reducing the possibility of permanent deformation. The buffer layer set on the seal body further improves the buffering effect, and the reinforcing plate set on the partition plate can improve the strength of the seal and prevent breakage.

[0005] While existing patents offer solutions that improve cushioning through the use of components such as buffers, they still suffer from poor sealing in practical use. This affects the elevator's operating efficiency and passengers' sense of security. Furthermore, they fail to effectively prevent external noise, dust, and moisture from entering the elevator car, thus reducing the comfort of the riding environment. Summary of the Invention

[0006] The purpose of this utility model is to provide a high-sealing soft and hard door seal for elevator landing doors, which can close the gaps in the elevator door when the elevator door is closed, improve the sealing performance, and prevent external noise, dust, moisture and other external factors from entering the elevator car, thereby improving the comfort of the riding environment and solving the problems mentioned in the background art.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figure 1 and Figure 2 A high-sealing elevator landing door soft and hard door seal includes a connecting plate 1, a support plate 2 fixedly installed at the front end of the connecting plate 1, and a sealing mechanism 3 provided on the outside of the support plate 2. The sealing mechanism 3 includes a receiving pad 301, which is sleeved on the outside of one support plate 2. The inner wall of the receiving pad 301 has a locking groove 302. A buffer pad 303 is embedded at the front end of the receiving pad 301. The buffer pad 303 has a buffer groove 304 inside. A sealing layer 305 is sleeved on the outside of another support plate 2. An insertion block 306 is fixedly installed on the outer wall of the sealing layer 305. The two sides of the outer wall of the insertion block 306 have locking grooves 307. The buffer pad 303 is tightly fitted with the sealing layer 305. The sealing layer 305 is bonded to the support plate 2. The outer dimensions of the insertion block 306 match the outer dimensions of the locking groove 302. The insertion block 306 is tightly fitted with the receiving pad 301.

[0028] By adopting the above technical solution, when the elevator door closes, it drives the support plates 2 fixed by the two connecting plates 1 to move relative to each other, so that the insertion block 306 is inserted into the engagement groove 302 of the receiving pad 301, and the buffer pad 303 is squeezed through the buffer groove 304 to reserve the compression and shrinkage space, and passes into the slot 307 to improve the sealing performance. It also works with the sealing layer 305 to further improve the sealing performance. The receiving pad 301, the buffer pad 303, and the sealing layer 305 are all made of rubber, and the insertion block 306 is made of hollow metal material with an outer rubber layer, thereby improving the sealing effect.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, a mounting groove 4 is provided inside the receiving pad 301 on the side near the buffer pad 303. A disassembly and assembly mechanism 5 is provided inside the mounting groove 4. The disassembly and assembly mechanism 5 includes a locking block 501, which is slidably connected inside the mounting groove 4. A connecting plate 502 is fixedly installed on one side of the inside of the buffer groove 304. A buffer spring 503 is embedded on one side of the outer wall of the connecting plate 502. The disassembly and assembly mechanism 5 also includes a fixing rod 504, which is fixed on the other side of the outer wall of the connecting plate 502. A support rod 505 is fixed at one end of the fixing rod 504 that passes through the locking block 501. The fixing rod 504 and the support rod 505 are perpendicular to each other. The fixing rod 504 passes through the inside of the locking block 501.

[0030] By adopting the above technical solution, the locking block 501 is made of rubber and slides into the receiving pad 301 along the placement groove 4. It is convenient to disassemble and assemble when the buffer pad 303 is damaged due to long time. The fixing rod 504 protruding from the inside of the buffer pad 303 is inserted into the locking block 501 and is fixed with the support rod 505 to improve the hardness of the locking block 501. At the same time, the connecting plate 502 is fixed at one end of the fixing rod 504 that is inserted into the buffer pad 303. The connecting plate 502 can quickly recover after the buffer pad 303 loses its compression through the embedded buffer spring 503.

[0031] Working principle: Two connecting plates 1 are fixed to both sides of the elevator door by bolts or fasteners, respectively. At the same time, the receiving pad 301 and the sealing layer 305 are respectively bonded by two support plates 2. When the elevator closes, the insert block 306 is inserted into the locking groove 302 of the receiving pad 301 and squeezes the buffer pad 303 through the space reserved for deformation in the buffer groove 304, so that it can enter the locking groove 307 for limiting, thereby improving the sealing performance when closing. The locking block 501 is supported by the support rod 505 and has a certain rigidity. At the same time, it is fixedly connected to the buffer pad 303 through the cooperation of the fixing rod 504 and the connecting plate 502. The locking block 501 is inserted into the placement groove 4 for easy and quick disassembly and assembly with the receiving pad 301, and can be replaced when damaged. The buffer spring 503 fixed by the connecting plate 502 is used to elastically support the buffer pad 303 to restore its original state after the elevator door opens and closes.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
