Description

Technical Field

[0001] The utility model relates to the technical field of electronic screen equipment, in particular to a ground stand, a supporting frame group and a ground screen. Background Art

[0002] When laying a floor screen on an uneven surface to be installed, in order to ensure that the floor screen is stably supported on the uneven surface and does not collapse locally, and to ensure the flatness of the floor screen, the floor screen usually 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. It 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.

[0059] 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 surface to be installed on which the anchor is laid has a high degree of unevenness, a large number of foot cups need to be adjusted, and the operation process is cumbersome, resulting in low installation efficiency and difficult operation.

[0060] Based on this, the inventors of this application attempted to provide a positioning assembly on the side 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 assembly is provided as a coarse positioning assembly and a fine positioning assembly. The coarse positioning assembly can guide the downstream anchor frame to move to a position where the locking assembly can be locked. During the locking process of the locking assembly, the downstream anchor frame moves with the locking assembly until it is locked and matched with the fine positioning assembly. Due to the coarse positioning assembly and the fine positioning assembly, the downstream anchor frame can be placed in the approximate installation position before installation. Coarse positioning can be achieved by moving the downstream anchor frame toward the installation position. Then, the downstream anchor frame can be accurately locked and installed by operating the locking assembly, making the installation of the anchor frame simple and easy to operate.

[0061] On this basis, the inventor sets the coarse positioning assembly in a plug-in matching mode, which can limit the position of the downstream ground support along the Z direction when the coarse positioning assembly is matched, so that even if the downstream ground support is in the pit position, the pressure of the downstream ground support sinking is transmitted to the upstream ground support to be borne together, so that the downstream ground support can be adjusted without adjusting the foot cup at the pit position when installed, but will not affect the stability of the support frame group as a whole.

[0062] The utility model will be described in further detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the utility model, and not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

[0063] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0064] In the utility model, unless otherwise explicitly specified and limited, the first feature "on" or "below" the second feature can include that the first and second features are in direct contact, or the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0065] In the description of the embodiment, the terms "up", "down", "right", etc. orientation or position relationship is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0066] In an embodiment of the present application, a floor screen is provided, which includes a support frame assembly arranged at a location to be installed and a screen body assembly supported on the support frame assembly. The support frame assembly not only provides installation support for the screen body assembly, but also compensates for the height of uneven locations on the surface to be installed, ensuring the flatness of the floor screen after it is laid. In addition, the support frame assembly allows a certain gap to be provided between the screen body assembly and the surface to be installed. The data lines or wires on the screen body assembly used to transmit electrical energy and signals can be accommodated in the gap, which not only ensures that the data lines or wires will not be damaged by external influences, but also ensures the overall aesthetics of the floor screen.

[0067] 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 and the floor screen is no longer used, it can be stored. This not only allows for greater flexibility in the decoration of the original installation space for the floor screen, but also reduces the risk of damage to the floor screen. In some embodiments of this application, please refer to Figure 1 As shown, the screen group includes multiple floor tile screens 2 that are detachably connected in sequence, and the support frame group includes multiple 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. Multiple floor tile screens 2 can be stacked and stored, and multiple ground anchors 1 can be stacked and stored.

[0068] Two adjacent floor tile screens 2 can be unlocked by simply operating the unlocking assembly, which is convenient. 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 the precise installation position, making it time-consuming and labor-intensive to assemble the support frame assembly, and the operation is difficult.

[0069] In order to solve the above problems, in some embodiments of this application, please refer to Figures 1-5 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. The frame body 10 includes a first side group 15 and a second side group 16 along a diagonal line. The coarse positioning assembly 20, the fine positioning assembly 40, and the locking assembly 30 each include two matching mating component groups, one of which is provided on the first side group 15 and the other is provided on the second side group 16. When the downstream anchor frame 1 is installed, the mating component group on the first side is precisely matched with the other mating component group on the upstream anchor frame 1.

[0070] For details, please refer to Figures 2-3As shown, the coarse positioning assembly 20 includes a first coarse positioning structure 21 and a second coarse positioning structure 22, the fine positioning assembly 40 includes a first fine positioning structure 41 and a second fine positioning structure 42, 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 disposed on one of the first side surface group 15 and the second side surface group 16, while the second coarse positioning structure 22, the second locking structure, and the second fine positioning structure 42 are disposed on the other. 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.

[0071] Please refer to Figures 2-3 As 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. Specifically, when the downstream anchor frame 1 is installed, the downstream anchor frame 1 is placed in the approximate position and can be moved diagonally toward the installation position. Then, during 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 is guided to move in the direction of matching with the second coarse positioning structure 22 on the upstream anchor frame 1, allowing the first coarse positioning structure 21 to extend into the second coarse positioning structure 22, thereby limiting the position of the downstream anchor frame 1 in the Z-axis direction and acting as a pressure transmitter. When the support frame assembly is locally subjected to pressure, the support frame assembly can resist the pressure as a whole, thereby increasing the overall rigidity of the support frame assembly. After the downstream anchor frame 1 is limited in the Z-axis direction, 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 lock within 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.

[0072] It should be noted that the frame 10 can be of different shapes, such as an even number of shapes such as a rectangle, a hexagon, and an octagon. When the frame 10 is rectangular, 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 each other on the other side of the diagonal. When the frame 10 is hexagonal, the first side group 15 is three consecutive sides on one side of the diagonal, and the second side group 16 is three consecutive 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. 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 anchor stand 1 is rectangular, so the following description will take the example in which 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 mating 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 mating component arranged on the second side group 16.

[0073] 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 Figures 2-3 As shown, at least one first mating component is provided on each of the two side surfaces of the first side surface group 15, and at least one second mating component is provided on each of the two side surfaces of the second side surface group 16. This allows the downstream anchor frame 1 to be guided by the coarse positioning component 20 when connected to the upstream anchor frame 1, and the downstream anchor frame 1 to move more smoothly. After the downstream anchor frame 1 is connected to the upstream anchor frame 1, the connection is more stable, and the pressure transmission is more uniform, making the overall pressure resistance of the support frame group stronger. There can be a first mating component at each end of the side surface belonging to the first side surface group 15, and a second mating component at each end of the side surface belonging to the second side surface group 16. Alternatively, there can be multiple first mating components spaced apart on the side surface belonging to the first side surface group 15, and multiple second mating components spaced apart on the side surface belonging to the second side surface group 16. As long as the number of first mating components is the same as the number of second mating components, this embodiment does not impose any specific restrictions.

[0074] In some embodiments of this application, please refer to Figures 2-5 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 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, allowing the support frame group to 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.

[0075] 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 Figures 2-5 As shown in the figure, the first coarse positioning structure 21 is provided with two first guide inclined surfaces 211 facing each other at the two ends of the side away from the frame 10 along the Z axis, and is provided with two second guide surfaces facing each other at the two sides along the length direction, and the second coarse positioning structure 22 is provided with a first matching surface 221 matched with the first guide inclined surface 211 and a second matching surface 222 matched with the second guide surface.

[0076] The inclined first guide inclined surface 211 and the second guide inclined surface 212 make the side of the first coarse positioning structure 21 away from the frame smaller in size, making it easier to enter the second coarse positioning structure 22, and making the first guide inclined surface 211 and the first matching surface 221 and the second guide surface and the second matching surface 222 more easily abut. When the first guide inclined surface 211 and the first matching surface 221 abut, or the second guide inclined surface 212 and the second matching surface 222 abut, the first matching surface 221 moves along the first guide inclined surface 211, and the second matching surface 222 moves along the second guide inclined surface 212, thereby achieving the purpose of guiding the downstream foot mounting direction and achieving the coarse positioning of the downstream foot stand 1.

[0077] Further, the inclination angle of the first guide inclined surface 211 and the second guide surface is 45 degrees, which can evenly divide the moving force of the downstream foot stand 1, so that the foot stand 1 has half of the moving force to drive the downstream foot stand 1 to move towards the mounting direction at any angle, thereby obtaining good guiding effect.

[0078] Since the ground screen has boundaries, the first coarse positioning structure 21 on the foot stand 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 edge wrapping or 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, and the first coarse positioning structure 21 is in the second position when it matches with the second coarse positioning structure 22, and the two sides of the first coarse positioning structure 21 along the Z direction are limited by the second coarse positioning structure 22. When the first coarse positioning structure 21 of the convex part 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.

[0079] Further, in some embodiments of the present application, the first coarse positioning structure 21 can move along the frame 10, and when it moves to the first position or the second position, it can be locked or unlocked with the frame 10 by screws, thereby realizing the switching of the first coarse positioning structure 21 between the first position and the second position.

[0080] In some embodiments of this application, please refer to Figure 2 and Figure 4 As 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 can be rotated around the rotating shaft 311 to rotate out of the locking groove 114, or it can be rotated 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 ground frame 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.

[0081] In order to ensure that the adjacent sides of two adjacent anchors 1 fit together without any gaps when locked, please refer to Figures 2-5 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 provided 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 the two adjacent anchor frames 1 are fitted together, thereby realizing the fitting between the adjacent side faces of the frame 10 of the two adjacent anchor frames 1 after the locking assembly 30 is locked.

[0082] In some embodiments of this application, please refer to Figures 2-5 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 groove is not only simple in structure but also easy to match. To prevent the edges on both sides of the protrusion from interfering with the matching of the protrusion and groove, in some embodiments of the present application, the protrusion is provided with third guide surfaces 411 inclined toward each other along the length direction, and the groove is provided with third mating surfaces 421 adapted to the third guide surfaces along the length direction. Because the third guide surfaces 411 are inclined surfaces, they can guide the anchor 1 to move the protrusion in the direction aligned with the groove until it matches the fine positioning assembly 40 when the locking assembly 30 is locked.

[0083] If the surface to be installed of the support frame group is relatively uneven, a small number of anchors 1 located in the concave areas will not cause any major problems if they rely on the strength of the support frame group as a whole. However, if a large number of anchors 1 located in the concave areas all rely on the support of anchors 1 located in the convex areas, the overall compressive strength of the support frame group will be affected. Therefore, in some embodiments of this application, please refer to Figures 2-3 As 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 have the same support height as 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.

[0084] 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. Each of the four corners of the square steel frame 11 is provided with a foot cup 14. A foot cup 14 is also provided at the connection between the cross-reinforcement beam 12 and the square steel 111, and a foot cup 14 is also provided at the center of the cross-reinforcement beam 12. The square steel frame 11 has a relatively high rigidity, which can increase the support strength of the frame 10. The cross-reinforcement beam 12 further increases the stability of the square steel frame 11 and improves the compressive strength of the frame 10. To ensure the overall shape of the frame 10 and avoid local deformation caused by the connection method, in some embodiments of the present application, the square steel frame 11 includes multiple square steels 111 spliced ​​end to end. For rectangular square steel frames 11, four square steels 111 are spliced ​​end to end. The four square steels 111 can be spliced ​​end to end by inserting the two sides of the right-angled corner piers 112 into the corresponding square steels 111 and connecting them using screws. The ends of the cross reinforcing beam 12 can be connected to the corresponding square steel 111 using a connecting block 13. The connecting block 13 includes an end sleeve that is sleeved on the end of the cross reinforcing 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 splicing of the cross reinforcing 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 good support for the floor tile screen 2.

[0085] Based on the support frame set described above, in some embodiments of the present application, a method for installing a support frame set is also provided, the method comprising:

[0086] S10, placing the downstream outrigger 1 in a general installation position;

[0087] S20, pushing the downstream outrigger 1 towards the installation position along the diagonal direction, the downstream outrigger 1 abuts against the upstream outrigger 1 for rough positioning, and the upstream outrigger 1 limits the displacement of the downstream outrigger 1 along the Z-axis direction;

[0088] S30, operating the locking assembly 30 to lock the downstream outrigger 1 and the upstream outrigger 1, and moving the downstream outrigger 1 along the X-axis and Y-axis directions for fine positioning;

[0089] S40, repeating the above process until all the outriggers 1 are installed.

[0090] In the S20 step, after the downstream outrigger 1 abuts against the upstream outrigger 1, the first rough positioning structure 21 and the second rough positioning structure 22 of the downstream outrigger 1 abut under the action of the pushing force towards the installation position, and are guided to move towards the installation position by the first guide slope 211 and the second guide slope 212, so as to realize rough positioning, and the first rough positioning structure 21 cannot move along the Z-axis direction under the limitation of the second rough positioning structure 22, thereby realizing that the upstream outrigger 1 limits the displacement of the downstream outrigger 1 along the Z-axis direction after rough positioning.

[0091] In the S30 step, after the downstream outrigger 1 abuts against the upstream outrigger 1, the first locking member 31 rotates out of the locking groove 114 and then hooks on the second locking member 32, and after the first locking member 31 abuts against the second locking member 32, the second locking member 32 gives the abutting force to the first locking member 31 with the rotation of the first locking member 31, so as to drive the frame body 10 to move along the X-axis and Y-axis directions under the action of the abutting force, so that the downstream outrigger 1 moves to the installation position which is fitted with the upstream outrigger 1 and in which the first fine positioning structure 41 cooperates with the second fine positioning structure 42.

[0092] In this whole process, the operator does not need to accurately position the downstream outrigger 1, thereby avoiding the problem of installation difficulty caused by misalignment between the downstream outrigger 1 and the upstream outrigger 1. According to the embodiments of the present application, the outrigger 1 only needs to be placed in the approximate position of the installation position, and then an approximate pushing force is applied to the downstream outrigger 1 towards the installation position, so as to realize rough positioning of the downstream outrigger 1, and fine positioning of the downstream outrigger 1 can be realized by operating the locking assembly 30 to lock, which is simple to operate and has high installation efficiency.

[0093] 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.
