[0001] This utility model relates to the field of flooring technology, and in particular to a raised floor. Background Technology

[0002] Raised floors are a type of modular flooring where the floorboards are installed on supports, creating a space between the floorboards and the ground. This space can be used for wiring or ventilation, and for maintenance, repair, or cable installation and removal. Raised floors are commonly used in computer rooms, equipment rooms, open-plan offices, and mobile buildings. Currently, raised floors are fixedly connected, requiring disassembly for stacking and storage, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a raised floor that uses lifting rods to lift the panels, making it easy to fold and store the panels.

[0004] To achieve the above objectives, this utility model provides a raised floor, comprising: at least two panels, which are rotatably connected to each other so that they can be unfolded and folded, and the connection position of the two panels is close to the lower surface of the panels; at least one panel is provided with a lifting rod at its bottom, which is rotatably connected to the panel so that it can support the unfolded panel, and the lifting rod can extend and retract relative to the panel in the vertical direction so that it can lift the connected panel to change the included angle between the two panels.

[0005] In some embodiments, the lower surface of the plate has a first receiving groove, one end of the lifting rod is hinged to the plate and disposed in the first receiving groove, and the lifting rod can rotate relative to the plate and enter the first receiving groove for storage.

[0006] In some embodiments, the rotation axis of the lifting rod is parallel to the rotation axis of the plate, and the first receiving groove has a first end and a second end disposed opposite to each other, the second end being away from the rotation axis of the plate, and the lifting rod being hinged to the second end.

[0007] In some embodiments, the lifting rod includes a third hinge, a driving member, and a lifting rod body. The third hinge is disposed in the first receiving groove. One end of the driving member is rotatably connected to the plate body through the third hinge, and the other end of the driving member is used to drive the lifting rod body to reciprocate.

[0008] In some embodiments, the lifting rod includes a support pad mounted on the end of the lifting rod body away from the drive member.

[0009] In some embodiments, a support rod is included, one end of which is hinged to the plate. The lower surface of the plate has a second receiving groove, and one end of the support rod is disposed in the second receiving groove. The second receiving groove is used to receive the support rod, and the support rod is spaced apart from the lifting rod.

[0010] In some embodiments, the support rod includes a fourth hinge and a support rod body. The fourth hinge is disposed in the second receiving groove, and one end of the support rod body is rotatably connected to the plate body through the fourth hinge, so that the support rod body is in a supported state or a stored state.

[0011] In some embodiments, one end of the support rod has a first abutting surface, which abuts against the lower surface of the plate when the support rod is in a supported state.

[0012] In some embodiments, one end of the support rod has a second abutment surface, which abuts against the side wall of the second receiving groove when the support rod is in a supported state.

[0013] In some embodiments, the panel includes an outer frame, a first crossbar and a second crossbar mounted on the outer frame, and a plurality of panels.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1-7As shown, the raised floor of this utility model embodiment includes: at least two panels 11, which are rotatably connected to each other, allowing them to be unfolded and folded, with the connection point of the two panels 11 close to the lower surface of the panels 11; at least one panel 11 has a lifting rod 12 at its bottom, which is rotatably connected to the panel 11, allowing the lifting rod 12 to support the unfolded panel 11, and the lifting rod 12 can extend and retract relative to the panel 11 in the vertical direction, allowing the lifting rod 12 to lift the connected panel 11 to change the included angle between the two panels 11. The panel 11 and the lifting rod assembly 12 combine to form a panel assembly 1.

[0027] Specifically, the raised floor also includes: a first hinge 2 and a second hinge 3. The panel 11 has an upper surface, a lower surface, and first and second ends arranged opposite to each other. The first ends of two adjacent panels 11 are rotatably connected by the first hinge 2, and the second ends of two adjacent panels 11 are rotatably connected by the second hinge 3. The first hinge 2 is installed on the lower surface of the panel 11, and the second hinge 3 is installed on the upper surface of the panel 11. The first hinge 2 and the second hinge 3 are hinges or latches.

[0028] In this embodiment, the lifting rod 12 is used to support or lift the plate 11. When the lifting rod 12 lifts the plate 11, the first ends of two adjacent plates 11 rotate around the first hinge 2 and move upward, while the second ends of two adjacent plates 11 rotate around the second hinge 3 and move downward. When the lifting rod 12 is used for support, its position is fixed, and the support keeps each plate 11 in a horizontal position.

[0029] The specific process of lifting plate 11 by lifting rod 12 is as follows: 1, 1, as Figure 1 As shown, the lifting rod 12 supports the plate 11, and each plate 11 is in a horizontal position. At this time, the horizontal plane where the first hinge 2 is located is below the horizontal plane where the first hinge 2 is located.

[0030] II. As Figure 2 As shown, the lifting rod 12 extends, lifting the plate 11 so that the first ends of the two adjacent plates 11 rotate around the first hinge 2 and move upward, and the second ends of the two adjacent plates 11 rotate around the second hinge 3 and move downward. At this time, the first hinge 2 and the second hinge 3 are on the same horizontal plane.

[0031] III. III. As Figure 3As shown, the lifting rod 12 continues to extend, lifting the plate 11 so that the first ends of the two adjacent plates 11 rotate around the first hinge 2 and continue to move upward, and the second ends of the two adjacent plates 11 rotate around the second hinge 3 and continue to move downward. At this time, the horizontal plane where the first hinge 2 is located is above the horizontal plane where the first hinge 2 is located, thus facilitating the folding and storage of each plate 11.

[0032] It should be noted that the lifting rod 12 only lifts the plate 11. The rotation and storage of the plate 11 is achieved by applying a force in the horizontal direction to bring the two plates 11 closer together. Since the lifting rod 12 lifts the plate 11, the included angle between the two plates 11 changes. The force applied in the horizontal direction can then drive the two plates 11 to rotate around the first hinge 2, thus achieving folding.

[0033] Based on the above structural configuration, when the lifting rod 12 lifts the plate 11, the first ends of the two adjacent plates 11 rotate around the first hinge 2 and move upward, and the second ends of the two adjacent plates 11 rotate around the second hinge 3 and move downward, so that the lower surfaces of the two adjacent plates 11 come closer to each other and the upper surfaces of the two adjacent plates 11 come closer to each other, which facilitates the folding and storage of each plate.

[0034] like Figure 5 and 6 As shown, in some embodiments, the lower surface of the plate 11 has a first receiving groove 111. One end of the lifting rod 12 is hinged to the plate 11, and the other end of the lifting rod 12 is disposed in the first receiving groove 111. The lifting rod 12 can rotate relative to the plate 11 and enter the first receiving groove 111 for storage. Thus, by rotating the lifting rod 12 to make it perpendicular to the plate 11, the lifting rod 12 supports the plate 11. By rotating the lifting rod 12 to make it parallel to the plate 11, the lifting rod 12 is stored in the first receiving groove 111.

[0035] In some embodiments, the rotation axis of the lifting rod 12 is parallel to the rotation axis of the plate 11, and the first receiving groove 111 has a first end and a second end disposed opposite to each other. The second end is away from the rotation axis of the plate 11, and the lifting rod 12 is hinged to the second end. In this way, the lifting rod 12 is hinged to one end away from the rotation axis of the plate 11, so that when the lifting rod 12 is raised a small distance, the plate 11 can be raised a longer distance.

[0036] like Figure 6As shown, in some embodiments, the lifting rod 12 includes a third hinge 121, a driving member 122, and a lifting rod body 123. The third hinge 121 is disposed within the first receiving groove 111. One end of the driving member 122 is rotatably connected to the plate body 11 via the third hinge 121, and the other end of the driving member 122 is used to drive the lifting rod body 123 to reciprocate. Thus, the driving member 122 can rotate around the third hinge 121, thereby adjusting the position of the driving member 122 to achieve a storage or support function. The driving member 122 drives the lifting rod body 123 to reciprocate, thereby achieving the function of lifting the plate body 11.

[0037] like Figure 6 As shown, in some embodiments, the lifting rod 12 includes a support pad 124, which is mounted on the end of the lifting rod body 123 away from the drive member 122. Thus, when the lifting rod 12 supports the plate body 11, the support pad 124 is positioned on the ground, providing an anti-slip effect.

[0038] In some embodiments, the lifting rod 12 is one of a hydraulic rod, a pneumatic rod, and an electric actuator. The hydraulic rod is connected to a hydraulic power source to achieve the lifting function, the pneumatic rod is connected to a pneumatic power source to achieve the lifting function, and the electric actuator is connected to a power source to achieve the lifting function.

[0039] like Figure 5 As shown, in some embodiments, the plate assembly 1 includes a support rod 13, one end of which is hinged to the plate 11. The lower surface of the plate has a second receiving groove 116, and one end of the support rod 13 is disposed within the second receiving groove 116. The second receiving groove 116 is used to accommodate the support rod 13, and the support rod 13 is spaced apart from the lifting rod 12. In this way, the support rod 13 can increase the number of support points of the plate 11, making the support structure of the plate 11 more stable.

[0040] like Figure 5 and 7 As shown, in some embodiments, the support rod 13 includes a fourth hinge 131 and a support rod body 132. The fourth hinge 131 is disposed within the second receiving groove 116. One end of the support rod body 132 is rotatably connected to the plate body 11 via the fourth hinge 131, so that the support rod body 132 is in a supported state or a retracted state. Thus, by rotating the support rod 13 to make it perpendicular to the plate body 11, the support rod 13 supports the plate body 11; by rotating the support rod 13 to make it parallel to the plate body 11, the support rod 13 is retracted into the second receiving groove 116.

[0041] During the use of the raised floor, it will be subjected to load-bearing force. At this time, the board 11 will transfer the load-bearing force to the support rod 132. If the board 11 and the support rod 132 are only connected by the fourth hinge 131, when the load-bearing force is too large, the pin of the fourth hinge 131 will be deformed or broken due to excessive force, making it impossible for the board 11 and the support rod 132 to rotate normally, thus affecting the normal use of the raised floor.

[0042] like Figure 7 As shown, in some embodiments, one end of the support rod 132 has a first abutment surface 132a. When the support rod 132 is in a supported state, the first abutment surface 132a abuts against the lower surface of the plate 11. Thus, when the plate 11 is subjected to excessive load, the plate 11 undergoes slight deformation. At this time, the first abutment surface 132a can support the lower surface of the plate 11, increasing the force-bearing area of ​​the plate 11, reducing the force on the fourth hinge 131, making the fourth hinge 131 less prone to damage, thereby increasing the load-bearing capacity of the plate 11 and reducing the deformation of the plate 11.

[0043] Since the plate 11 and the support rod 132 are connected by the fourth hinge 131, when the plate 11 is subjected to a horizontal force, the support rod 132 and the plate 11 will rotate relative to each other, which will affect the stability of the entire raised floor.

[0044] like Figure 7 As shown, in some embodiments, one end of the support rod 132 has a second abutment surface 132b. When the support rod 132 is in a supported state, the second abutment surface 132b abuts against the side wall of the second receiving groove 116. Preferably, two support rods 132 are installed on each plate 11, and the second abutment surfaces 132b of the two support rods 132 face opposite directions. In this way, the second abutment surface 132b abuts against the side wall of the second receiving groove 116, which can restrict the rotation of the support rod 132 and facilitate adjusting the support rod 132 to be perpendicular to the plate 11. Furthermore, since the second contact surfaces 132b of the two support rods 132 face opposite directions, when the plate 11 is subjected to a horizontal force, there is always a second contact surface 132b of one support rod 132 that abuts against the side wall of the second receiving groove 116, thereby limiting the position of the plate 11 and preventing relative rotation between the support rods 132 and the plate 11, thus ensuring the stability of the entire raised floor.

[0045] like Figure 5As shown, in some embodiments, the plate 11 includes an outer frame 112, a first crossbar 113 and a second crossbar 114 mounted on the outer frame 112, and multiple plates 115. The first crossbar 113 and the second crossbar 114 divide the internal space of the outer frame 112 into multiple mounting positions, and the multiple plates 115 are mounted one-to-one in the multiple mounting positions. In this way, when a plate 115 is damaged, a single plate 115 can be disassembled for replacement or repair, reducing usage costs.

[0046] like Figure 4 As shown, rotating the lifting rod 12 and the support rod 13 causes the lifting rod 12 to be housed in the first receiving groove 111 and the support rod 13 to be housed in the second receiving groove 116. Figure 3 Based on the folding and storage of each plate 11 shown, each plate 11 is folded further so that the lower surfaces of two adjacent plates 11 are in contact with each other and the upper surfaces of two adjacent plates 11 are in contact with each other, so that the structure between each plate component 1 is compact after folding.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
