Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

As shown in fig. 1, combine fig. 2 and fig. 3, the utility model discloses a booth apart from LED cell board convenient to installation is fixed, including cell board 1, still include bridging block 2, quick detach nut 3, gasket 4 and tension spring 5.

Wherein, cell board 1 includes plate body 11 and screw rod 12, and plate body 11 is the cuboid board, and the breach 13 of the same cuboid shape is all seted up at four angles in plate body 11 bottom, and two liang of adjacent three open faces of breach 13 flush with two liang of adjacent three faces of plate body 11 base angle respectively, and screw rod 12 has eight, and the equal vertical fixed connection in the top of per two screw rods 12 is on one breach 13 top face and two screw rods 12 all set up along the direction of the long limit axis of breach 13 top face. It should be noted that, preferably, the distance between the two screws 12 is equal to the length of the wide side of the notch 13, so that the plate bodies 11 of two adjacent unit plates 1 can be tightly attached as much as possible.

The bridging block 2 is a rectangular block, two through holes 21 are formed in pairs in the top end face of the bridging block 2 along the direction of a long edge, and the bridging block 2 is movably sleeved between the two screw rods 12 through the two through holes 21 and located in the gap 13 to connect and fix the two adjacent plate bodies 11.

Quick detach nut 3 installs in 12 bottoms of screw rod and hugs closely in bridging piece 2 bottom faces for fix bridging piece 2, simultaneously through rotatory quick detach nut 3, can be very convenient adjust the board face roughness to plate body 11.

Tension spring 5 installs on screw rod 12, and both ends are connected between 13 top end faces of breach and 2 top end faces of bridging piece about tension spring 5, utilize tension bounce-back of tension spring 5, have formed effectual fixed action to plate body 11 in the tension spring 5 both ends and bridging piece 2, have played the cushioning effect simultaneously, avoid the mutual extrusion force between bridging piece 2 and the plate body 11 too big, lead to the risk that plate body 11 damaged.

The spacer 4 is connected between the bottom end of the tension spring 5 and the top end face of the bridging block 2, and also plays a certain role in buffering the extrusion force between the bridging block 2 and the plate body 11.

By adopting the technical scheme, when the plate edge or the plate corner of the plate body 11 of one unit plate 1 is tilted and higher than the adjacent unit plate 1, the quick-release nut 3 in the notch 13 of the tilted end of the plate body 11 is rotated to shorten the distance between the bridging block 2 and the plate body 11, so that the tilted end of the plate body 11 moves towards the bridging block 2, and the two adjacent plate bodies 11 are adjusted to the same flat surface.

Specifically, the invention is also realized by the following technical scheme.

Preferably, the plate body 11 further includes a positioning strip 14, and the positioning strip 14 is vertically disposed on two side surfaces of the plate body 11; the plate body 11 is further provided with a sliding groove 15, the sliding groove 15 is vertically arranged on the other two side surfaces of the plate body 11, the positioning strip 14 is matched with the sliding groove 15 in shape, a good limiting effect is achieved, the situation that the adjacent unit plates 1 are deviated left and right or up and down is avoided, and meanwhile, the single unit plates 1 are convenient to disassemble and take out from the whole matrix of the unit plates 1.

As some optional embodiments, the two wide sides of the bridging block 2 are in a semicircular arc shape, so that the bridging block 2 can rotate in the gap 13 conveniently.

As some alternative embodiments, the plate body 11 may also be a square plate. It should be noted that the present solution is also applicable to a backing plate or a bottom plate on which the LED unit board 1 is mounted.

The working principle is as follows:

a plurality of unit plates 1 are arranged in a matrix and aligned, and the positioning strips 14 and the sliding grooves 15 of the adjacent plate bodies 11 are matched with each other.

As shown in fig. 2, a bridging block 2 is installed in each of the notches 13 at the four corners where the four unit boards 1 adjacent to each other in the vertical and horizontal directions are closely attached to each other. All quick detach nuts 3 are unscrewed, and the positions of four bridging blocks 2 are adjusted, as shown in fig. 2, so that one bridging block 2 is connected between two adjacent plate bodies 11, and finally the quick detach nuts 3 are installed and screwed, so that good tightness and firmness can be ensured between the adjacent unit plates 1.

As shown in fig. 1, when the plate edge or plate corner of the plate body 11 of one unit plate 1 is tilted and higher than the adjacent unit plate 1, the quick release nut 3 in the notch 13 of the tilted end of the plate body 11 is rotated. Because bridging block 2 one end is fixed in on the adjacent plate body 11, consequently bridging block 2's position is fixed, and rotatory quick detach nut 3 can shorten bridging block 2 and plate body 11's distance, and then makes plate body 11's perk end move to bridging block 2's direction to make two adjacent plate bodies 11 adjusted to same planishing face.

When a single or a plurality of connected unit plates 1 need to be disassembled and replaced, the quick-release nuts 3 fixed at four corners of the corresponding unit plates 1 are only required to be screwed off, so that the unit plates 1 are separated from the adjacent unit plates 1 in a fixed connection relationship, then the unit plates 1 are upwards pushed, the unit plates can be conveniently taken out from the matrix of the unit plates 1, and meanwhile, the installation stability of other unit plates 1 cannot be influenced.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
