[0002] When laying a floor screen on an uneven surface to be installed, in order to ensure that the floor screen is stably supported in the uneven place and does not collapse locally, and to ensure the flatness of the floor screen, usually the floor screen includes a screen group and a support frame group. The screen group is installed on the support frame group, and the support frame group is laid on the uneven surface to be installed, which can not only compensate for the uneven surface to be installed, but also provide stable support for the screen group, ensuring the flatness and aesthetics of the floor screen.

[0003] Since the support frame group is composed of multiple anchor frames arranged at one time, the interlocking and locking structures between two adjacent anchor frames must be aligned to achieve connection.

[0067] When a traditional anchor is installed on an uneven surface to be installed, there is no guide structure between the downstream anchor and the upstream anchor. Therefore, the first locking structure and the second locking structure that can lock and unlock the downstream anchor and the upstream anchor need to be precisely aligned to achieve locking, which is not easy to operate. In addition, the side of the anchor that abuts the surface to be installed is usually provided with a foot cup that can be adjusted in height. By adjusting the foot cup, the height of the uneven surface to be installed can be compensated. However, due to the lack of rigidity of the existing anchor, when the unevenness rate of the surface to be installed on which the anchor is laid is relatively high, a large number of foot cups need to be adjusted, and the operation process is cumbersome, resulting in low installation efficiency and difficult operation.

[0068] Based on this, the inventor of the present application tried to set a positioning component on the side of the frame of the anchor frame that can guide the downstream anchor frame to align with the upstream anchor frame. However, considering that the positioning of two adjacent anchor frames is not accurate before they are locked, the positioning component is set as a coarse positioning component and a fine positioning component. The coarse positioning component can guide the downstream anchor frame to move to a position where the locking component can be locked. During the locking process of the locking component, the downstream anchor frame moves with the locking component until it is locked to match the fine positioning component. Due to the coarse positioning component and the fine positioning component, the downstream anchor frame is placed in the approximate installation position before installation. The coarse positioning can be achieved by moving the downstream anchor frame toward the installation position. Then, the precise locking and installation of the downstream anchor frame can be achieved by operating the locking component to lock it, making the installation of the anchor frame simple and easy to operate.

[0069] On this basis, the inventor arranges the coarse positioning component in a plug-in matching manner. When the coarse positioning component is matched, it can limit the position of the downstream anchor frame along the Z direction, so that even when the downstream anchor frame is in the pit position, the pressure of the downstream anchor frame sinking due to the coarse positioning component is transmitted to the upstream anchor frame to share the responsibility. Therefore, when installing the downstream anchor frame, if the foot cup at the pit position is inconvenient to adjust, it does not need to be adjusted, but it will not affect the stability of the overall support of the support frame group.

[0070] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0071] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0073] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0074] In an embodiment of the present application, a floor screen is provided, which includes a support frame group arranged at a position to be installed and a screen body group supported on the support frame group. The support frame group can not only provide installation support for the screen body group, but also compensate for the height of the uneven position of the surface to be installed, ensuring the flatness of the floor screen after it is laid. In addition, the support frame group allows a certain gap between the screen body group and the surface to be installed, and the data line or wire on the screen body group used to transmit electrical energy and signals can be accommodated in the gap, which can not only ensure that the data line or wire will not be damaged by external influences, but also ensure the overall aesthetics of the floor screen.

[0075] Floor screens are often used on stages or in exhibition halls to give the audience an immersive viewing experience. When the performance or exhibition is over, if the floor screen is no longer used, it can be stored, which not only allows the original installation space of the floor screen to have greater decoration flexibility, but also reduces the risk of damage to the floor screen. Figure 1 As shown, the screen body group includes a plurality of floor tile screens 2 that are detachably connected in sequence, and the support frame group includes a plurality of ground anchors 1 that are connected in sequence. When the floor screen needs to be disassembled, the floor tile screens 2 and the ground anchors 1 can be disassembled in sequence, and a plurality of floor tile screens 2 and a plurality of ground anchors 1 can be stacked and stored.

[0076] Two adjacent floor tile screens 2 can be unlocked by directly operating the unlocking assembly, which is convenient to operate. However, when installing the floor screen, the unlocking assembly needs to be aligned before it can be locked. During this process, the operator needs to move the downstream anchor frame 1 to a precise installation position, so it is time-consuming and laborious to assemble the support frame group, and the operation is difficult.

[0077] In order to solve the above problems, in some embodiments of the present application, please refer to Figure 1 to Figure 5 As shown, the anchor frame 1 includes a frame body 10, a coarse positioning assembly 20, a fine positioning assembly 40 and a locking assembly 30, wherein the frame body 10 includes a first side group 15 and a second side group 16 opposite to each other along a diagonal line, and the coarse positioning assembly 20, the fine positioning assembly 40 and the locking assembly 30 each include two matching matching component groups, wherein one matching component is disposed on the first side group 15, and the other matching component is disposed on the second side group 16. When the downstream anchor frame 1 is installed, the matching component group on the first side is matched and connected with the other matching component group on the upstream anchor frame 1.

[0078] For more information, see Figure 2-3 As shown, the coarse positioning assembly 20 includes a first coarse positioning structure 21 and a second coarse positioning structure 22 adapted to each other, the fine positioning assembly 40 includes a first fine positioning structure 41 and a second fine positioning structure 42 adapted to each other, and the locking assembly 30 includes a first locking structure and a second locking structure that can be locked and unlocked. The first coarse positioning structure 21, the first locking structure, and the first fine positioning structure 41 are arranged on one of the first side surface group 15 and the second side surface group 16, and the second coarse positioning structure 22, the second locking structure, and the second fine positioning structure 42 are arranged on the other one. The first coarse positioning structure 21, the first locking structure and the first fine positioning structure 41 may be arranged on the first side group 15, and the second coarse positioning structure 22, the second locking structure and the second west positioning structure may be arranged on the second side group 16; or the first coarse positioning structure 21, the second locking structure and the first fine positioning structure 41 may be arranged on the first side group 15, and the second coarse positioning structure 22, the first locking structure and the second west positioning structure may be arranged on the second side group 16; or the second coarse positioning structure 22, the second locking structure and the first fine positioning structure 41 may be arranged on the second side group 16, and the second coarse positioning structure 22, the first locking structure and the second west positioning structure may be arranged on the second side group 16; as long as the coarse positioning component 20 can match, the fine positioning component 40 can match, and the locking component 30 can match when the downstream anchor frame 1 is installed, this embodiment does not make any specific limitations.

[0079] Please refer to Figure 2-3As shown, the coarse positioning assembly 20 of the embodiment of the present application can guide the installation direction of the anchor frame 1 and limit the position of the frame body 10 in the Z-axis direction. In detail, when the downstream anchor frame 1 is installed, the downstream anchor frame 1 is placed in a general position, and the downstream anchor frame 1 can be moved to the installation position along the diagonal direction. Then, in the process of matching the first coarse positioning structure 21 with the second coarse positioning structure 22, the first coarse positioning structure 21 on the downstream anchor frame 1 will be guided to move in the direction of matching with the second coarse positioning structure 22 on the upstream anchor frame 1, so that the first coarse positioning structure 21 can extend into the second coarse positioning structure 22, thereby limiting the position of the downstream anchor frame 1 in the Z-axis direction and playing a role in pressure conduction, so that when the support frame group is locally subjected to pressure, the support frame group can resist the pressure as a whole, thereby achieving the effect of increasing the overall rigidity of the support frame group. After the Z-axis direction of the downstream anchor frame 1 is limited, although there is still a certain deviation from the target position in the X-axis and Z-axis directions, the deviation is not large, so the locking assembly 30 can be locked under this deviation. During the locking process, the downstream anchor 1 moves along the X-axis and Y-axis directions due to the abutment force to eliminate the deviation, so the fine positioning assembly 40 is matched after locking.

[0080] It should be noted that the frame 10 can be in different shapes, such as an even number of shapes such as a rectangle, a hexagon, and an octagon. When the frame 10 is a rectangle, the first side group 15 is two adjacent sides that are perpendicular to each other, and the second side group 16 is two adjacent sides that are perpendicular to the other side of the diagonal. When the frame 10 is a hexagon, the first side group 15 is three sequentially connected sides on one side of the diagonal, and the second side group 16 is three sequentially connected sides on the other side of the diagonal. The number of sides included in the first side group 15 and the second side group 16 is related to the shape of the frame 10, and the sides located on both sides of the diagonal can be divided into the first side group 15 and the second side group 16. Typically, the foot stand 1 is rectangular, and therefore the following description will take the example that the first side group 15 and the second side group 16 both include two adjacent perpendicular side surfaces, and the first coarse positioning structure 21, the first locking structure and the first fine positioning structure 41 constitute a first matching component arranged on the first side group 15, and the second coarse positioning structure 22, the second locking structure and the second fine positioning structure 42 constitute a second matching component arranged on the second side group 16.

[0081] In order to ensure the stability of the connection between the downstream anchor frame 1 and the upstream anchor frame 1, in some embodiments of the present application, please refer to Figure 2-3As shown, at least one first matching component is provided on both sides of the first side group 15, and at least one second matching component is provided on both sides of the second side group 16, so that when the downstream anchor frame 1 is connected with the upstream anchor frame 1, it is guided by the coarse positioning component 20 and moves more smoothly, and after the downstream anchor frame 1 is connected with the upstream anchor frame 1, the connection is more stable, and the pressure transmission is more uniform, so that the overall pressure resistance of the support frame group is stronger. There can be a first matching component at each end of the side of the first side group 15, and a second matching component at each end of the side of the second side group 16, or there can be multiple first matching components spaced apart on the side of the first side group 15, and multiple second matching components spaced apart on the side of the second side group 16, as long as the number of the first matching components is the same as the number of the second matching components, this embodiment does not make any specific restrictions.

[0082] In some embodiments of this application, please refer to Figure 2 to Figure 5 As shown, the first coarse positioning structure 21 is a positioning protrusion, and the second coarse positioning structure 22 is a positioning groove. When the positioning protrusion is inserted into the positioning groove, the bottom surface of the positioning protrusion abuts against the lower groove wall of the positioning groove, and the positioning groove can support the positioning protrusion. When the installation position of the downstream anchor frame 1 is relatively low, the gravity of the anchor frame 1 is sequentially transmitted to the multiple upstream anchor frames 1 through the positioning protrusion and the positioning groove, so that the support frame group can bear the weight of the local anchor frame 1 as a whole. In addition, under the action of the gravity of the anchor frame 1, the upstream anchor frame 1 limits the displacement of the downstream anchor frame 1 in the Z-axis direction.

[0083] In order to facilitate the matching of the first coarse positioning structure 21 and the second coarse positioning structure 22, in some embodiments of the present application, please refer to Figure 2 to Figure 5 As shown, the first coarse positioning structure 21 is provided with first guide slopes 221 inclined toward each other at both ends along the Z axis on the side facing away from the frame body 10, and the first coarse positioning structure 21 is provided with second guide surfaces inclined toward each other on both sides along the length direction, and the second coarse positioning structure 22 has a first mating surface 211 adapted to the first guide slope 221, and a second mating surface 222 adapted to the second guide surface.

[0084] The inclined first guide bevel 221 and the second guide bevel 212 make the side of the first coarse positioning structure 21 away from the frame smaller, making it easier to enter the second coarse positioning structure 22, and making it easier for the first guide bevel 221 and the first mating surface 211, as well as the second guide surface and the second mating surface 222 to abut. When the first guide bevel 221 abuts against the first mating surface 211, or the second guide bevel 212 abuts against the second mating surface 222, the first mating surface 211 moves relatively along the first guide bevel 221, and the second mating surface 222 moves relatively along the second guide bevel 212, thereby achieving the purpose of guiding the installation direction of the downstream anchor and achieving the coarse positioning of the downstream anchor frame 1.

[0085] Furthermore, the inclination angle between the first guide slope 221 and the second guide surface is 45 degrees, which can evenly divide the moving force of the downstream anchor frame 1, so that half of the moving force of the anchor frame 1 drives the downstream anchor frame 1 to move toward the installation direction at any angle, thereby obtaining a good guiding effect.

[0086] Since the ground screen has a boundary, the first coarse positioning structure 21 on the anchor frame 1 constituting the boundary of the support frame group is in the shape of the convex frame 10, which will not only interfere with other structures, such as the edging or the lifting stage. Therefore, in some embodiments of the present application, the first coarse positioning structure 21 has a first position extending out of the frame 10 and a second position retracted into the frame 10. When the first coarse positioning structure 21 matches the second coarse positioning structure 22, the first coarse positioning structure 21 is in the second position, and the two sides of the first coarse positioning structure 21 along the Z direction are limited to the second coarse positioning structure 22. When the first coarse positioning structure 21 in the convex position interferes with other structures or affects the overall aesthetics of the support frame group, the first coarse positioning structure 21 can be switched to the second position retracted into the frame 10.

[0087] Furthermore, in some embodiments of the present application, the first coarse positioning structure 21 can move along the frame 10. When it moves to the first position or the second position, the first coarse positioning structure 21 can be locked or unlocked with the frame 10 by using screws, thereby realizing the switching of the first coarse positioning structure 21 between the first position and the second position.

[0088] In some embodiments of this application, please refer to Figure 2 and Figure 4As shown, the first locking structure includes a rotating shaft 311 and a locking hook 312. The rotating shaft 311 is arranged on the side of the frame 10 along the Z-axis direction. The side of the frame 10 can have a locking groove 114, and the rotating shaft 311 is arranged in the locking groove 114. The locking hook 312 is arranged on the rotating shaft 311. The locking groove 114 around the rotating shaft 311 is a space for the locking hook 312 to rotate. It is virtual that it can rotate around the rotating shaft 311 to rotate out of the locking groove 114, and it can also rotate around the rotating shaft 311 to rotate until it is accommodated in the locking groove 114. The second locking structure is a lock column. After the lock hook 312 rotates out of the locking groove 114, the end of the lock hook 312 abuts against the lock column, and as the lock hook 312 rotates, the end of the lock hook 312 applies a driving force to the lock column to move toward the inside of the lock hook 312, thereby enabling the downstream anchor 1 to move along the X-axis and Y-axis directions when the locking assembly 30 is locked. When the locking assembly 30 is locked, the first fine positioning structure 41 is aligned and matched with the second fine positioning structure 42.

[0089] In order to make the adjacent sides of two adjacent anchors 1 fit together without gaps when they are locked, please refer to Figure 2 to Figure 5 As shown, a locking groove 113 is provided on the side of the upstream frame 10 at a position matching the locking groove 114, and a locking column is arranged in the locking groove 113. When the locking hook 312 is locked with the locking column, the locking hook 312 can be accommodated in the locking groove 113. The length of the locking hook 312 matches the distance between the axis of the rotating shaft 311 and the axis of the locking column when two adjacent anchor frames 1 are fitted together, thereby realizing the fitting between the adjacent sides of the frame 10 of the two adjacent anchor frames 1 after the locking assembly 30 is locked.

[0090] In some embodiments of this application, please refer to Figure 2 to Figure 5 As shown, one of the first fine positioning structure 41 and the second fine positioning structure 42 is a protrusion and the other is a groove. The structure of the protrusion and the groove is not only simple in structure but also easy to match. In order to avoid the edges on both sides of the protrusion interfering with the matching of the protrusion and the groove, in some embodiments of the present application, the protrusion is provided with third guide surfaces 411 inclined toward each other on both sides along the length direction, and the groove is provided with third matching surfaces 421 adapted to the third guide inclined surfaces on both sides along the length direction. Since the third guide surface 411 is an inclined surface, it can guide the anchor 1 to drive the protrusion to move in the direction aligned with the groove to match the fine positioning component 40 when the locking component 30 is locked.

[0091] If the surface to be installed of the support frame group is relatively uneven, there is no big problem if a small number of anchors 1 located in the concave parts rely on the support of the overall strength of the support frame group. However, if a large number of anchors 1 located in the concave parts rely on the support of anchors 1 located in the convex parts, it will affect the overall compression resistance of the support frame group. Therefore, in some embodiments of the present application, please refer to Figure 2-3As shown, a plurality of height-adjustable foot cups 14 are provided at intervals on the lower side of the frame 10. When the ground frame 1 is installed in a relatively concave place, the flatness of the installation position can be compensated by adjusting the height of the foot cups 14 below the frame 10, so as to support the ground frame 1 to be consistent with the support height of other ground frames 1, and ensure the overall rigidity of the entire support frame group. During the installation of the ground frame 1, due to the limitation of the installation space, it is difficult to adjust some of the foot cups 14 below the frame 10. Since the frame 10 is also supported by other foot cups 14 and can also be supported by the upstream ground frame 1, when the foot cups 14 are difficult to adjust, the height of the foot cups 14 can be omitted to maintain the consistency of the support surface of the support frame, and the overall compressive strength of the support frame group will not be affected too much. The use of such a solution reduces the difficulty of installing the support frame group and improves the installation efficiency.

[0092] In some embodiments of the present application, the frame 10 includes a square steel frame 11 and a cross reinforcement beam 12 connected to the center of the square steel frame 11. A foot cup 14 is provided at each of the four corners of the square steel frame 11. A foot cup 14 is also provided at the connection between the cross reinforcement beam 12 and the square steel 111. A foot cup 14 is also provided at the center of the cross reinforcement beam 12. The rigidity of the square steel frame 11 is relatively high, which can increase the support strength of the frame 10. The cross reinforcement beam 12 can further increase the stability of the square steel frame 11 and improve the compressive strength of the frame 10. In order to ensure the overall shape of the frame 10, the problem of local deformation caused by the connection method is avoided. Therefore, in some embodiments of the present application, the square steel frame 11 includes a plurality of square steels 111 spliced ​​end to end. For the rectangular square steel frame 11, it is formed by splicing four square steels 111 end to end. The two sides of the right-angle pier 112 can be inserted into the corresponding square steel 111, and the connection is made by screwing, thereby realizing the end to end splicing of the four square steels 111. The end of the cross reinforcement beam 12 can be connected to the corresponding square steel 111 by using a connecting block 13. The connecting block 13 includes an end sleeve mounted on the end of the cross reinforcement beam 12 and an L-shaped connecting plate connected to the end sleeve. The vertical side of the L-shaped connecting plate is connected to the end of the end sleeve, and the horizontal side is abutted against the square steel 111, and then a threaded connection is used to achieve the splicing of the cross reinforcement beam 12 and the square steel frame 11. The splicing not only has reliable connection strength but also can ensure the flatness of the frame 10, ensuring that good support is provided for the floor tile screen 2.

[0093] Based on the above-mentioned support frame assembly, some embodiments of the present application further provide a method for installing the support frame assembly, the method comprising:

[0094] S10, placing the downstream anchor bracket 1 at an approximate installation position;

[0095] S20, pushing the downstream anchor frame 1 to the installation position along the diagonal direction, the downstream anchor frame 1 abuts against the upstream anchor frame 1 for rough positioning, and the upstream anchor frame 1 limits the displacement of the downstream anchor frame 1 along the Z-axis direction;

[0096] S30, operating the locking assembly 30 to lock the downstream anchor frame 1 with the upstream anchor frame 1, and the downstream anchor frame 1 moves along the X-axis and Y-axis directions for precise positioning;

[0097] S40, repeat the above process until all the anchors 1 are installed.

[0098] In step S20, after the downstream anchor frame 1 abuts against the upstream anchor frame 1, the first coarse positioning structure 21 of the downstream anchor frame 1 abuts against the second coarse positioning structure 22 under the action of the thrust toward the installation position, and the anchor frame 1 is guided by the first guide slope 221 and the second guide slope 212 to move toward the installation position until the first coarse positioning structure 21 is inserted into the second coarse positioning structure 22 to achieve coarse positioning. Under the restriction of the second coarse positioning structure 22, the first coarse positioning structure 21 cannot move along the Z-axis direction, thereby achieving the upstream anchor frame 1 limiting the displacement of the downstream anchor frame 1 along the Z-axis direction after coarse positioning.

[0099] In step S30, after the downstream anchor frame 1 abuts against the upstream anchor frame 1, the first locking piece 31 rotates out from the locking groove 114 and then hooks onto the second locking piece 32. After the first locking piece 31 abuts against the second locking piece 32, as the first locking piece 31 rotates, the second locking piece 32 applies an abutting force to the first locking piece 31. Under the action of the abutting force, the first locking piece 31 drives the frame body 10 to move along the X-axis and Y-axis directions, so that the downstream anchor frame 1 moves to a mounting position where it fits with the upstream anchor frame 1 and the first fine positioning structure 41 cooperates with the second fine positioning structure 42.

[0100] During this entire process, the operator does not need to accurately position the downstream anchor frame 1, thereby avoiding the problem of installation difficulties caused by the misalignment of the downstream anchor frame 1 and the upstream anchor frame 1. The anchor frame 1 provided in the embodiment of the present application only needs to be placed in the approximate position of the installation position and then a rough thrust is applied to the downstream anchor frame 1 to move toward the installation position to achieve the rough positioning of the downstream anchor frame 1. The downstream anchor frame 1 can be accurately positioned by operating the locking assembly 30 to lock it. The operation is simple and the installation efficiency is high.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
