Description

Technical Field

[0001] The invention relates to the technical field of elevator door panels, in particular to an elevator door panel capable of automatically changing width. Background Art

[0002] Nowadays, there are more and more high-rise buildings, and each high-rise building basically has to install elevators. The installation of elevators can greatly facilitate people's travel and the transportation of goods. With the popularity of elevators, more and more elevator accidents have occurred. Through investigation, it was found that violent damage to elevator doors accounted for a large part of the accidents.

[0003] The width of the elevator door opening is a very important indicator for users. Whether it is passengers or goods entering and exiting, the elevator car hopes that the door opening is as large as possible and as convenient as possible. Some users may encounter goods that are larger than the net width of the door opening and cannot go upstairs through the elevator. It takes a lot of manpower and material resources to ask a crane to lift the goods from the window of the building and deliver them to the room, which is both expensive and dangerous. In addition, the design of the elevator door opening width is limited by the width of the elevator shaft. Traditional elevator doors are generally center-split or side-opening, and the door panels are double-fold or triple-fold. Taking the conventional design of the center-split door as an example, the net width of the shaft must be greater than the operating space of the door opening width, and the shaft width is often limited by on-site conditions, so this problem has always plagued elevator designers.

[0004] Therefore, it is necessary to provide an elevator door panel that can automatically widen to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: traditional elevator doors are generally center-split or side-opening, and the door panels have double fold or triple fold. Taking the conventional design of center-split doors as an example, the net width of the shaft must be larger than the door opening width operating space, and the shaft width is often limited by on-site conditions, so this problem has always plagued elevator designers.

[0007] The technical solution adopted by the present application to solve the technical problem is: an elevator door panel that can automatically change width, comprising:

[0008] Limiting frame;

[0009] A connecting plate, fixedly connected to the two limiting frames, and the two connecting plates are arranged parallel to each other;

[0010] A closing mechanism, arranged on the limiting frame, to close and seal the device;

[0011] A parasitic door panel is slidably connected to the connecting plate;

[0012] A main door panel, slidably connected to the parasitic attached door panel;

[0013] An adjusting unit, arranged on the limiting frame, for controlling the opening and closing size of the closing mechanism;

[0014] A limiting mechanism, arranged on the limiting frame, for limiting the moving direction of the closing mechanism;

[0025] The beneficial effects of the present application are as follows: A slidable parasitic attached door panel is designed on the elevator door panel. When the driving motor is started, the rotating shaft fixedly arranged at the output end of the driving motor rotates. During the rotation of the rotating shaft, the sprocket fixedly arranged on the rotating shaft rotates, the chain connected between the two sprockets rotates, and the positioning rod on the chain drives the main door panel to move through the connecting rod and retracts into the parasitic attached door panel during the door opening process, thereby reducing the space occupied by the main door panel in the door opening state. During the elevator door closing process, the widened parasitic attached door panel and the main door panel start to slide together in the door closing direction. When sliding to the position required for the widening design, the main door panel slowly extends from the widened parasitic attached door panel until the main door panel is closed, and the widened parasitic attached door panel extends to the designed widened size. For safety protection, after the widened door panel reaches the designed width, the widened parasitic attached door panel cannot continue to extend, achieving the effect of a small space and a large door opening. It breaks through the traditional design concept, fills the industry gap, and obtains social and economic benefits.

[0036] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0037] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0038] Refer to Figures 1-3, an elevator door panel that can automatically change width, comprising: a limit frame 1; a connecting plate 2, fixedly connected to two limit frames 1, and the two connecting plates 2 are arranged parallel to each other; a closing mechanism 3, arranged on the limit frame 1, to realize closing and sealing of the device; a parasitic door plate 31, slidably connected to the connecting plate 2; a main door plate 32, slidably connected to the parasitic door plate 31; an adjusting unit 33, arranged on the limit frame 1, for controlling the size of the opening and closing of the closing mechanism 3; a limit mechanism 4, arranged on the limit frame 1, for limiting the direction of movement of the closing mechanism 3; a limit groove 1 41, opened on the limit frame 1, and the parasitic door plate 31 is slidably connected to the limit groove 1 41; a limit groove 2 42, arranged on the limit frame 1, and the main door plate 32 is slidably arranged on the limit groove 2 42, and the width of the limit groove 1 41 is not less than the width of the limit groove 2 42.

[0039] Reference Figures 4-6 A groove 311 is provided on the parasitic door panel 31, and the main door panel 32 is slidably connected in the groove 311. A plurality of springs 312 parallel to each other are fixedly arranged on the bottom end of the groove 311, and the other end of the spring 312 is fixedly connected to the main door panel 32. A disassembly unit 313 for disassembling the parasitic door panel 31 is provided on the parasitic door panel 31. The sliding connection between the parasitic door panel 31 and the main door panel 32 is realized by the groove 311 provided on the parasitic door panel 31. The spring 312 provided in the groove 311 can ensure that the sliding arrangement on the parasitic door panel 31 can push the main door panel 32 inside it to move.

[0040] Reference Figures 4-6 When the cam 313 is in the unlocking state, the locking cam 3134 is in the unlocking state, and the locking cam 3134 is in the unlocking state.

[0041] Reference Figure 1 , 2As shown in FIGS. 6 and 7, the adjusting unit 33 includes a positioning plate 331 fixedly connected to the limit frame 1. Between the two positioning plates 331, two parallel rotating shafts 332 are rotatably connected. A driving motor 333 is fixedly connected to the positioning plate 331. The output end of the driving motor 333 is fixedly connected to the rotating shaft 332. On the outer circumferential surfaces of the two rotating shafts 332, sprockets 334 are fixedly arranged. A chain 335 is drivingly connected between the two sprockets 334. On the outer circumferential surface of the chain 335, two parallel positioning rods 336 are fixedly arranged. An adjusting rod 337 is movably connected between the positioning rod 336 and the main door panel 32. When the staff needs to adjust the opening and closing size of the main door panel 32, the staff starts the driving motor 333. When the driving motor 333 rotates, the rotating shaft 332 fixedly connected to its output end rotates, and the sprocket 334 fixedly arranged on the outer circumferential surface of the rotating shaft 332 rotates, so that the chain 335 connected between the two sprockets 334 rotates. The rotating chain 335 drives the adjusting rod 337 to move through the positioning rod 336 fixedly arranged on its outer surface, and the moving adjusting rod 337 can drive the main door panel 32 to move.

[0042] Refer to Figures 6-8 , a long plate 5 is fixedly arranged on the parasitic attached door panel 31 and the main door panel 32. A shaft body 51 is fixedly arranged on the long plate 5 of the main door panel 32. The shaft body 51 is slidably connected to the long plate 5 of the parasitic attached door panel 31. A third spring 52 is fixedly arranged between the two long plates 5. When the main door panel 32 moves, the shaft body 51 fixedly arranged on the main door panel 32 moves. When the shaft body 51 contacts the long plate 5 of the parasitic attached door panel 31, the parasitic attached door panel 31 moves, realizing the opening of the closing mechanism 3 of the elevator.

[0043] Refer to Figures 4-6 , a clamping post 511 is fixedly arranged at the end of the shaft body 51. The diameter of the clamping post 511 is not less than the diameter of the shaft body 51. By arranging the clamping post 511 at the end of the shaft body 51, when the shaft body 51 moves, the clamping post 511 at its end can ensure that the main door panel 32 will not fall off during the moving process.

[0044] Refer to Figures 1-3 , a convex plate 6 is fixedly arranged on one of the main door panels 32, and a positioning groove 61 matching the convex plate 6 is formed on the other main door panel 32. By arranging the convex plate 6 and the positioning groove 61 on the two main door panels 32, it is convenient for the two main door panels 32 to fit together more easily when they are closed and connected.

[0045] Refer to Figures 1-3 , an antistatic protective film is coated on the outer surfaces of the parasitic attached door panel 31 and the main door panel 32. By coating the antistatic protective film on the parasitic attached door panel 31 and the main door panel 32, the safety of the device during use is ensured, and harm to people is avoided.

[0046] Reference Figure 1 , 2 and 6, the length of the shaft body 51 is not less than the length of the main door panel 32, and by setting the length relationship between the shaft body 51 and the main door panel 32, it is ensured that the main door panel 32 can be completely compressed into the parasitic door panel 31 during the movement of the shaft body 51.

[0047] Reference Figures 1-3 The corner of the main door panel 32 is arc-shaped, and a rubber pad is fixedly provided on one adjacent end of the main door panel 32. The rubber pad provided at the corner of the main door panel 32 increases its elasticity, and can reduce the damage to the body caused by the main door panel 32 when a collision occurs.

[0048] The specific solution is as follows: when the staff needs to adjust the opening and closing size of the main door panel 32, the staff starts the driving motor 333. When the driving motor 333 rotates, the rotating shaft 332 fixedly connected to the output end thereof rotates, and the sprocket 334 fixed on the outer circumference of the rotating shaft 332 rotates, thereby causing the chain 335 connected between the two sprockets 334 to rotate. The rotating chain 335 drives the connecting rod 337 to move through the positioning rod 336 fixed on the outer surface thereof. The moving connecting rod 337 can drive the main door panel 32 to move, and when the main door panel 32 moves, the shaft body 51 fixed on the main door panel 32 moves. When the shaft body 51 is aligned with the parasitic door panel 31, the connecting rod 337 can move. When the long board 5 on the upper part contacts, the parasitic door panel 31 moves to open the closing mechanism 3 of the elevator. When the staff needs to check the internal parts of the parasitic door panel 31, the convex plate 6 and the positioning groove 61 set on the two main door panels 32 make it easier for the two main door panels 32 to fit together when closed and connected. The staff manually moves the slide plate 3134, and the slide plate 3134 moves to press down the spring 2 3135. At this time, the limiting rod 3137 on the slide plate 3134 is disengaged from the limiting hole 3136. At this time, the card plate 3132 is in a sliding state, and the staff can directly manually remove the card plate 3132, which is convenient for the staff to inspect the inside of the parasitic door panel 31.
