[0040] As a construction equipment, on the premise of achieving its purpose, the simpler and more practical the structure is, the more convenient it is to maintain. For the floor doors previously applied by the applicant that use rollers to realize the up and down movement of the door body, or the floor doors that use the way of sliding grooves and sliders to realize the movement, there are all some problems to a certain extent, such as inconvenient maintenance, or large production and processing difficulty, etc., resulting in difficult cost control. Therefore, this application proposes a floor door with a new structure.

[0041] The following will detail a new type of up and down linkage floor door of this application through the following embodiments.

[0042] Embodiment 1:

[0043] As Figures 1-4As shown in the figure, in this embodiment, an up-and-down linkage floor door includes: a door frame 1, and the door frame 1 includes: two side rods 11 symmetrically arranged; a door body 2; and an annular part which is sleeved on the side rods 11 in an up-and-down movable manner and is connected to the door body 2.

[0044] Among them, the door body 2 is arranged on the door frame 1 in an up-and-down movable manner through the annular part.

[0045] As a safety door on the building floor, a floor door needs to be installed on each floor, resulting in a very large demand. Moreover, due to the long construction time of the building and the large number of times the floor door is repeatedly opened and closed, the quality and cost of the inner door of the floor are very important. Based on this, on the basis of the original design concept, this application improves the up-and-down sliding structure of the door body 2, so that not only can the production cost be greatly reduced, but also the sliding structure is very firm and not easily damaged.

[0046] Specifically, since the door body 2 needs to slide up and down on the two side rods 11 on both sides of the door frame 1, for this reason, an annular part is provided on the door body 2. By sleeving the annular part on the side rods 11, the door body 2 can be installed on the two side rods 11 and can move up and down.

[0047] It should be noted that there is no special limitation on the structure of the side rods 11. Its cross-section can be circular, oval, square or other polygonal structures, as long as the annular part can slide up and down on the side rods 11. Optimally, in order to reduce friction and wear, the side rods 11 can be set as cylindrical, and the annular part can be circular.

[0048] It should be noted that in order to ensure the installation strength of the two side rods 11 and prevent them from tilting, the door frame 1 further includes: a bottom beam 13 and a top beam 12. Both ends of the bottom beam 13 and the top beam 12 are connected to the two side rods 11; among them, the bottom beam 13 is located below the side rods 11, and the top beam 12 is located above the side rods 11. By setting the top beam 12 and the bottom beam 13, the two side rods 11 are made more firm.

[0049] It should be noted that regarding the linkage of the door body 2, after the elevator reaches the corresponding floor, when the door on the elevator opens upward, there is a hook-shaped structure on the door, and this hook-shaped structure contacts the linkage component on the door body 2, and then applies an upward thrust to the linkage component, thereby driving the door body 2 to open upward synchronously; conversely, when the door on the elevator closes downward, the door body 2 on the floor door also moves downward simultaneously under the action of gravity, thereby closing the door body 2.

[0050] Embodiment Two:

[0051] This embodiment is a further improvement made on the basis of Embodiment One.

[0052] As Figures 1-4 shown, in this embodiment, the door body 2 includes: an upper door body 21; and a lower door body 22, which is arranged up and down with the upper door body 21; there are four groups of annular parts, which are divided into a first upper annular part 301, a first lower annular part 302, a second upper annular part 303 and a second lower annular part 304;

[0053] Among them, the first upper annular part 301 is arranged on one side or both sides of the upper side of the upper door body 21, and the first lower annular part 302 is arranged on one side or both sides of the lower side of the upper door body 21; the second upper annular part 303 is arranged on one side or both sides of the upper side of the lower door body 22; the second lower annular part 304 is arranged on one side or both sides of the lower side of the lower door body 22.

[0054] To prevent the top of the door body 2 from being too high after rising to the maximum opening degree, on the one hand, it interferes with the floor door on the upper floor, resulting in the need to stagger the floor doors; on the other hand, it leads to the need to make the entire door frame 1 structure very large. For this reason, the door body 2 is divided into an upper door body 21 and a lower door body 22. The lower door body 22 is driven by the door on the elevator to move upward, and then after the lower door body 22 moves a certain height, the lower door body 22 drives the upper door body 21 to move upward together, which not only realizes the large opening of the door body 2, but also limits the height of the door body 2.

[0055] Specifically, the lower door body 22 moves up and down on the side rod 11 through the second upper annular part 303 and the second lower annular part 304, and the upper door body 21 moves up and down on the side rod 11 through the first upper annular part 301 and the first lower annular part 302. It should be noted that to ensure the stability of the upper door body 21 and the lower door body 22 on the side rod 11, for this reason, the first upper annular part 301, the first lower annular part 302, the second upper annular part 303, and the second lower annular part 304 are all set to two, which are respectively arranged on both sides of the upper door body 21 and the lower door body 22 and are connected to the two side rods 11.

[0056] It should be noted that to prevent the upper door body 21 from sliding down under its own gravity to overlap with the lower door body 22, for this reason, a limiting part 4 for limiting the sliding height of the upper door body 21 is also arranged on the side rod 11.

[0057] For the height limit of the lower door body 22, it can be limited by the ground on the floor or by the upper door body 21.

[0058] Specifically, the lower side of the upper door body 21 and the upper side part of the lower door body 22 are reset, and then the first lower annular part 302 is located below the second upper annular part 303; among them, the first lower annular part 302 is used to limit the sliding height of the lower door body 22.

[0059] When the entire door body 2 is in the closed state, the upper door body 21 is limited by the limiting portion 4 on the side rod 11 at this time, so that it hangs on the two side rods 11, and the lower door body 22 is hung on the two first lower annular portions 302 on the upper door body 21 through the two second upper annular portions 303 thereon.

[0060] Embodiment 3:

[0061] This embodiment is a further improvement made on the basis of the above Embodiment 2.

[0062] As Figure 2 and Figure 3 shown, in this embodiment, the structure of the limiting portion 4 is not limited, as long as it can achieve the function of limiting the first annular portion, for example, by providing a convex structure on the side rod 11.

[0063] Optimally, for the convenience of installation, for this purpose, there is a through hole 111 penetrating horizontally on the side rod 11; the limiting portion 4 includes: a bolt 41, the head of which is located on the side rod 11, and the rod portion thereof passes through and extends out of the side rod 11 through the through hole 111; and a nut 42, which is threadedly connected to the rod portion of the bolt 41.

[0064] After this setting, after the upper door body 21 slides down to a certain height, the first upper annular portion 301 will be blocked by the bolt 41, thereby restricting the further sliding down of the first upper annular portion 301 and the upper door body 21. By using the bolt 41 and the nut 42 as the limiting portion 4, on the one hand, it is convenient for installation; on the other hand, it can also adjust the position of the limiting portion 4 on the side rod 11 according to the actual situation of the floor, that is, adjust the height of the upper door body 21.

[0065] Specifically, a plurality of through holes 111 are provided on the side rod 11 along its height direction, and according to the actual situation, the screw rod and the nut 42 can be installed in one of the through holes 111.

[0066] Embodiment 4:

[0067] This embodiment is a further improvement made on the basis of Embodiments 2 and 3.

[0068] As Figures 1-4 shown, in this embodiment, the annular portion includes: a connecting ring 31; and a connecting member 32, one end of which is connected to the connecting ring 31, and the other end is connected to the upper door body 21 or the lower door body 22.

[0069] The connecting ring 31 is the main component of the annular portion. In order to install it on the door body 2, a connecting member 32 is also provided for this purpose. The connecting member 32 can be set as an L-shaped structure, one end of which is welded or installed on the door body 2 by other means, and the other end is used to weld the connecting ring 31. Under the action of the connecting member 32, the installation strength of the connecting ring 31 is improved.

[0070] It should be noted that for the connecting ring 31 on the first upper annular part 301, it can be blocked by the limiting part 4; while the connecting rings 31 on the first lower annular part 302, the second upper annular part 303 and the second lower annular part 304 cannot be blocked by the limiting part 4 to prevent the lower door body 22 from moving upward. Therefore, an opening 311 is provided on the connecting rings 31 of the first lower annular part 302, the second upper annular part 303 and the second lower annular part 304; wherein, during the process of the lower door body 22 driving the upper door body 21 to move upward, the connecting rings 31 on the first lower annular part 302, the second upper annular part 303 and the second lower annular part 304 can pass through the limiting part 4 through their openings 311.

[0071] The embodiments of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications or improvements to the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the embodiments disclosed herein.
