Of course, the number of the splicing units is not limited by the same splicing screen, only two splicing units can be spliced together, three or more splicing units can be spliced together, and each splicing unit can be arranged in a row, for example, arranged along the horizontal direction, and also can be arranged in a row and column manner.

Referring to fig. 1 to 6, the mounting seat 21 includes a connecting member 211 for connecting the splicing unit, a supporting member 212, a driving member 213 and a locking member 214, the connecting member 211 is provided with a guide slot 2111, the connecting member 211 includes a first side plate 2112, a second side plate 2113 which are oppositely arranged, and a first bottom plate 2114 which connects the first side plate 2112 and the second side plate 2113 to form the guide slot 2111, that is, the first side plate 2112, the first bottom plate 2114 and the second side plate 2113 all extend along the extending direction of the guide slot 2111 and are connected in sequence to form a semi-annular slot type structure, the opposite direction of the first side plate 2112 and the second side plate 2113 is perpendicular to the extending direction of the guide slot 2111, that is, the cross section of the guide slot 2111 perpendicular to the extending direction thereof is a semi-annular structure, and the semi-annular structure herein is a ring-shaped structure having an opening in the circumferential direction thereof and is not limited. The supporting member 212 is slidably coupled in the guiding slot 2111 along the extending direction of the guiding slot 2111, the driving assembly 213 is used for driving the supporting member 212 and the connecting member 211 to slide relatively, and the supporting member 212 and the connecting member 211 can be locked to each other by the locking assembly 214, i.e. when the connecting member 211 and the supporting member 212 slide relatively to a desired position, the two are locked by the locking assembly 214 to prevent the two from sliding continuously.

In the above embodiment, two splicing units are taken as an example for illustration, as shown in fig. 10 and fig. 11, for convenience of description, the two splicing units are respectively defined as a first splicing unit 11 and a second splicing unit 12, the first splicing unit 11 is connected to the supporting beam 22 through the mounting seat 21, the lower surface of the supporting member 212 abuts against the upper surface of the supporting beam 22 (i.e. the supporting member 212 is fixed relative to the supporting beam 22 in the following adjustment process), the second splicing unit 12 is mounted to the supporting beam 22 through other connecting structures, the extending direction is a vertical direction, i.e. the relative sliding direction of the connecting member 211 and the supporting member 212 is a vertical direction, in the initial stage of mounting, the upper surface of the first splicing unit 11 is higher than the upper surface of the second splicing unit 12 (as shown in fig. 11), the connecting member 211 is driven by the driving assembly 213 to slide downward relative to the supporting member 212, until the upper surface of the first splicing unit 11 is aligned with the upper surface of the second splicing unit 12, and then the connecting member 211 and the supporting member 212 are locked by the locking assembly 214 to prevent relative sliding. Obviously, the mounting base 21 of the present invention is provided with the connecting member 211 and the supporting member 212 which slide relatively, so that when the adjacent splicing units are dislocated during the installation of the splicing screen, the connecting member 211 can slide relative to the supporting member 212 to drive the splicing units connected thereto to move, so as to adjust the height of the splicing units in the vertical direction, and further align the splicing units with the adjacent splicing units. In addition, the invention considers that the relative sliding structure is adopted, the vertical direction can be deviated in the sliding process of the connecting piece 211, and even the connecting piece 211 is separated from the supporting piece 212, therefore, the guide groove 2111 of the connecting piece 211 forms an open ring structure through the first side plate 2112, the second side plate 2113 and the first bottom plate 2114, and the relative sliding between the supporting piece 212 and the connecting piece 211 is limited in at least three directions, so that the sliding of the connecting piece 211 can be better guided, the strength of the connecting piece 211 can be increased, the relative sliding stability of the connecting piece 211 and the supporting piece 212 is ensured, and the adjustment of the splicing unit is more stable. In addition, the splicing unit is usually larger, in order to increase the connection reliability, the connecting piece 211 needs to be arranged longer, and one of the two objects which slide relatively is arranged longer, in the invention, the guide groove 2111 is arranged on the connecting piece 211, the length of the connecting piece 211 is increased, when the splicing unit is connected, the connection reliability of the splicing unit and the connecting piece 211 can be increased, and the supporting piece 212 does not need to be arranged too long, so that the requirement of the relative sliding stroke can be met, therefore, the guide groove 2111 is arranged on the connecting piece 211, compared with the supporting piece 212, the space arrangement of the whole mounting seat 21 is more favorable, and the mounting reliability of the splicing unit can be improved.

The first side plate 2112, the second side plate 2113 and the first bottom plate 2114 may enclose a guide slot 2111 with a rectangular cross section, that is, the first side plate 2112, the second side plate 2113 and the first bottom plate 2114 are all of a flat plate structure, and the first side plate 2112 and the second side plate 2113 are both perpendicular to the first bottom plate 2114; the three parts can also form a U-shaped guide groove 2111, namely the first bottom plate 2114 is of an arc-shaped plate structure; or the three parts form a trapezoidal guide groove 2111, that is, the first side plate 2112, the second side plate 2113 and the first bottom plate 2114 are all of a flat plate structure, and the first side plate 2112 and the second side plate 2113 form a non-zero included angle with the first bottom plate 2114. Of course, the connecting member 211 may further include a first top board (not shown), which is connected to the first side board 2112 and the second side board 2113 at a side away from the first bottom board 211, and a distance is left between the two first top boards; the first top plate may be attached to only the first side plate 2112 or the second side plate 2113. The guide groove 2111 may be provided as a guide groove having another shape.

In order to further improve the smoothness of the sliding of the connecting member 211 and the supporting member 212, the supporting member 212 and the connecting member 211 may be at least partially formed in a shape of a contour, for example, in an embodiment, the supporting member 212 includes a third side plate 2121, a second bottom plate 2123, and a fourth side plate 2122, which are connected in sequence, the third side plate 2121 is disposed opposite to the first side plate 2112, the second bottom plate 2123 is disposed opposite to the first bottom plate 2114, and the fourth side plate 2122 is disposed opposite to the second side plate 2113, that is, the supporting member 212 is formed in a groove-shaped structure, so that the contact area between the supporting member 212 and the guide groove 2111 can be increased, the strength of the supporting member 212 can be increased, and.

Preferably, the guide slot 2111 is a rectangular slot, i.e. the first bottom plate 2114 and the second bottom plate 2123 are both of a flat plate structure, and the supporting member 212 is also of a rectangular slot structure, so as to further increase the smoothness of the relative sliding between the two. Moreover, the first bottom plate 2114 is configured to be a flat plate structure, and when the splicing unit is connected with the first bottom plate, the contact area between the splicing unit and the connecting piece 211 can be increased, and the connection reliability of the splicing unit and the connecting piece can be increased. Of course, only one of the first base plate 2114 and the second base plate 2123 may be a flat plate structure.

With continued reference to fig. 1-6, the driving assembly 213 includes an adjusting bolt 2131, a driving member 2132 connected to the connecting member 211, and an abutting member 2133 connected to the supporting member 212, wherein the driving member 2132 and the abutting member 2133 are disposed opposite to each other along the extending direction; the driving member 2132 is provided with a threaded hole 2132a, and the threaded hole 2132a penetrates through the driving member 2132 in the extending direction; when the adjusting bolt 2131 is in threaded fit with the threaded hole 2132a, one end of the adjusting bolt 2131 extends out of one side of the driving element 2132, which is close to the abutting piece 2133, and abuts against the abutting piece 2133, and in use, as shown in fig. 4, because the end of the adjusting bolt 2131 abuts against the upper surface of the abutting piece 2133, and the supporting piece 212 and the abutting piece 2133 are fixed relative to the supporting beam 22, the connecting piece 211 can be driven to slide upwards or downwards by rotating the adjusting bolt 2131, so that the relative sliding of the connecting piece 211 relative to the supporting piece 212 is realized.

Further, when the extending direction is vertical, the driving assembly 213 is located above the supporting member 212, i.e. on a side of the supporting member 212 away from the supporting beam 22, so that the acting force applied to the supporting member 212 by the adjusting bolt 2131 is always consistent with the gravity direction, thereby increasing the contact stability between the supporting member 212 and the supporting beam 22, and further facilitating the operation of the user.

The pushing part 2133 and the supporting part 212 may be an integral structure, or may be fixed together by welding, clamping, or screwing. Similarly, the driving element 2132 and the connecting element 211 may be integrated, or may be fixed together by welding, clamping, or screwing. Considering that in practical use, the splicing unit connected with the mounting seat 21 may be spliced with different splicing units, and the driving assembly 213 needs to be adjusted for multiple times during splicing, therefore, the threaded hole 2132a of the driving member 2132 may be threaded, the top of the pushing member 2133 may be worn, and the integral structure is not favorable for maintenance and replacement. In order to solve the above problems, in a preferred embodiment of the present invention, the driving element 2132 and the connecting element 211 form a detachable connecting structure, and the pushing element 2133 and the supporting element 212 form a detachable connecting structure, as shown in fig. 3, the driving assembly 213 further includes a screw 2134, the pushing element 2133 is connected with the supporting element 212 through the screw 2134, and the driving element 2132 is connected with the connecting element 211 through the screw 2134, so that the driving element 2132 and the pushing element 2133 are convenient to replace when damaged, and the maintenance cost is reduced.

More preferably, the driving element 2132 and the pushing element 2133 are block-shaped structures, and especially, the pushing element 2133 is preferably a block-shaped structure, or a projection of the block-shaped structure on a plane perpendicular to the extending direction is an annular structure, so as to increase the strength of the driving element 2132 and the pushing element 2133, and further improve the driving sensitivity of the driving assembly 213.

Further, the driving element 2132 is located in the guiding slot 2111 and connected to the first side plate 2112, the second side plate 2113 and the first bottom plate 2114, and thus, after the arrangement, the driving element 2132 can also function as a reinforcing structure, so as to prevent the guiding slot 2111 from deforming and increase the stability thereof. Of course, other reinforcing structures may be disposed at other positions of the guide slot 2111, for example, a plurality of reinforcing structures are disposed along the extending direction, and the reinforcing structures are flat plate structures connected to the first side plate 2112, the second side plate 2113 and the first bottom plate 2114. It will be appreciated that the reinforcing structure (or the driving member 2132) may also be connected with the first top plate when the connecting member 211 is provided with the first top plate.

Similarly, in the embodiment where the support 212 includes the third side plate 2121, the fourth side plate 2122 and the second bottom plate 2123, the push-piece 2133 is connected to the third side plate 2121, the fourth side plate 2122 and the second bottom plate 2123 to increase the strength of the support 212. Preferably, the pushing component 2133 is connected to an end of the supporting component 212 facing away from the supporting beam 22.

In addition, reinforcing ribs and the like may be provided on the first side plate 2112, the second side plate 2113, the first bottom plate 2114, the third side plate 2121, the fourth side plate 2122, and the second bottom plate 2123 to increase the strength of the connecting member 211 and the supporting member 212.

The driving assembly 213 may also be other driving structures, such as a linear motor, a hydraulic push rod, or a pneumatic tendon.

In order to prevent the connecting member 211 from deviating from the extending direction when sliding relative to the supporting member 212, even if the guide slot 2111 is separated from the supporting member 212, a limiting structure is disposed at an opening of the guide slot 2111, such as the first top plate, and a dimension of the first top plate in the extending direction may be unequal to the first bottom plate 2114, the first side plate 2112, or the second side plate 2113. In one embodiment, during the sliding of the connecting member 211 along the extending direction, if the sliding stroke of the connecting member 211 relative to the supporting member 212 is too large, it may cause the limiting plate of the supporting beam 22 to completely disengage from the limiting groove (described in detail below), which may cause the whole mounting seat 21 to disengage from the supporting beam 22, and if the mounting hidden trouble of the splicing unit may be increased, for this reason, a limiting structure may be disposed along the extending direction, which may be a protruding structure disposed on the connecting member 211, and at both ends of the sliding stroke allowed by the connecting member 211, the supporting member 212 abuts against the protruding structure to limit the sliding stroke of the connecting member 211 relative to the supporting member 212. That is, the mount base 21 may be provided with a stopper structure for restricting the extension direction by sliding, or may be provided with a stopper structure for restricting the direction perpendicular to the extension direction.

In a preferred embodiment, the mounting seat 21 further includes a limiting component 215, the limiting component 215 includes a first limiting hole 2151, a second limiting hole 2152 and a limiting member 2153, the first side plate 2112 and the second side plate 2113 are both provided with the first limiting hole 2151, the supporting member 212 is provided with the second limiting hole 2152, the first limiting hole 2151 penetrates the connecting member 211 along a direction perpendicular to the extending direction, the second limiting hole 2152 penetrates the supporting member 212 along a direction perpendicular to the extending direction and parallel to the first bottom plate 2114, at least one of the first limiting hole 2151 and the second limiting hole 2152 is a strip-shaped hole extending along the extending direction, the limiting member 2153 is inserted into the first limiting hole 2151 and the second limiting hole 2152, as shown in fig. 2, 3, 5 and 6, the connecting member 211 is provided with a circular hole (i.e., the first limiting hole 2151 is a non-strip-shaped hole), the supporting member is provided with a strip-shaped hole (i.e., the second limiting hole 2152 is a strip-shaped hole), the limiting member 2153 sequentially passes through the first limiting hole 2151, the second limiting hole 2152 and the first limiting hole 2151 from one side of the connecting member 211, so that the stroke of the connecting member 211 relative to the supporting member 212 is limited by the length of the strip-shaped hole, and the limiting member 2153 is arranged in the first limiting hole 2151 and the second limiting hole 2152, so that the supporting member 212 can be prevented from sliding out of the guide groove 2111 when the connecting member 211 slides relative to the supporting member 212, and therefore the connecting member 211 and the supporting member 212 can be limited in two directions by the limiting assembly 215; and with the structure, the relative sliding between the connecting piece 211 and the supporting piece 212 can be better guided. Of course, the first limiting hole 2151 may be a bar-shaped hole, the second limiting hole 2152 may be a circular hole, or both the first limiting hole 2151 and the second limiting hole 2152 may be bar-shaped holes.

In order to further improve the stability of the relative sliding between the connecting member 211 and the supporting member 212, at least two sets, such as two sets, three sets or more sets, are disposed on the limiting assembly 215 along the extending direction, and optionally, one set is disposed at each of two ends of the supporting member 212 along the extending direction.
