When the decorative wall board is installed in place, the connecting bulges between two adjacent splicing blocks and between the splicing blocks and the edge strips are clamped into the splicing grooves. Because the inclined splicing inclined planes between two adjacent splicing blocks are closely attached together, and the inclined splicing inclined planes between the splicing blocks and the edge strips are closely attached together with the lapping inclined planes, any one splicing block can only rotate towards one side of the splicing inclined plane far away from the adjacent splicing blocks, or rotate towards one side of the lapping inclined plane far away from the edge strips, and at the moment, the connection protrusions and the splicing grooves which are mutually clamped together can effectively prevent the splicing blocks from rotating. That is to say, this scheme makes all splice to link into an organic whole, can avoid the rotation of any one of them splice and separate and produce the gap with between its adjacent splice.
Preferably, the length of the clamping sliding groove is a, and a is less than or equal to B/3.
The length of the clamping sliding groove is controlled to be less than one third of the width of the splicing block, so that the fixing pin is eccentrically positioned on one side of the width direction of the splicing block. Like this, one side of each splice receives the location of fixed pin, and the opposite side receives the location of the connection arch of mutual joint and concatenation recess, has both been favorable to simplifying structure, easy to assemble, can ensure the reliable location of splice again, avoids forming the concatenation gap between the adjacent splice.

Therefore, the guide-in ports at the upper side and the lower side of the splicing block to be installed can be opposite to the fixing pins corresponding to the upper connecting piece and the lower connecting piece, and the splicing block and the decorative wallboard are inclined to form an included angle. After the fixed pin gets into in the joint spout, rotate the splice again, make splice the direction unanimous with decorating the wallboard, then remove the splice again, make the splice inclined plane of this splice front side and splice the inclined plane laminating of splicing or the overlap joint of strake of a splice rear side before with. That is, this scheme can reduce the required installation interval of installation splice remarkably, and especially, when installing to last two splices, its remaining installation clearance receives the restriction, and this scheme can ensure the easy to assemble of splice.

It can be understood that 8 wedge-shaped spaces can be formed between the round outer peripheral surface of the pin shaft and the square inner hole of the fixed sleeve, each wedge-shaped space is from the vertex angle of the square inner hole of the fixed sleeve to the middle position of the side length, when the maximum radial dimension of the vertex angle is set to be L1 and the minimum radial dimension of the middle position of the side length is L2, the diameter of the locking cylinder is larger than L2 and smaller than L1, so that the locking cylinder is positioned at the approximately middle position of the wedge-shaped space under the torque action of the torsion spring, and at the moment, the inner side surface of the fixed sleeve is tightly attached to the circumferential surface of the. When the pin shaft rotates forwards, the locking cylinder can be driven to roll towards one side of the maximum radial dimension by virtue of friction force, and the pin shaft can rotate smoothly at the moment; when the pin shaft rotates reversely, a tendency that the locking cylinder is driven to roll towards one side of the minimum radial dimension can be formed by means of friction force, and the pressure of the locking cylinder, the inner side face of the pin shaft and the inner side face of the fixing sleeve is correspondingly increased at the moment because the locking cylinder cannot roll towards one side of the minimum radial dimension. The locking cylinder can be conveniently self-locked by reasonably setting the sizes of the inner hole of the fixing sleeve, the diameter of the pin shaft, the diameter of the locking cylinder and the like, so that the reverse rotation of the pin shaft can be effectively prevented. Therefore, when the fixing pin enters the clamping sliding groove from the introducing port, the gear at the lower section of the pin shaft is meshed with the rack on one side inside the clamping groove, and the pin shaft is driven to rotate in the forward direction. When the splicing blocks are installed in place, the pin shafts are locked and cannot rotate reversely, so that the splicing blocks can be effectively prevented from moving reversely, and the splicing blocks are ensured to be clamped with the upper connecting strip and the lower connecting strip.
Therefore, the invention has the following beneficial effects: the on-site assembly type fixed installation of the decorative wall board can be realized, and the reliability of connection can be ensured.

Preferably, as shown in fig. 4, the upper connecting member may be formed by an extrusion process such that an upper long groove 32 extending in a transverse direction (i.e., a length direction of the upper connecting member) is formed at a middle position in a width direction of an upper side surface of the upper connecting member, a lower long groove 33 extending in the transverse direction is formed at a middle position in the width direction of a lower side surface of the upper connecting member, and a moving groove 34 penetrating the upper long groove is formed at a bottom surface of the lower long groove. In addition, the fixing pin includes a pin 311 movably located in the moving groove, and a stopper 312 integrally connected to an upper end of the pin and movably located in the upper long groove. The round pin axle includes the screw thread section of being connected with the stopper, and coaxial coupling is in the joint section of screw thread section lower extreme to the diameter of joint section is less than the diameter of screw thread section, and threaded connection has fastening nut 35 on the screw thread section.
Thus, in the steps d and e, the fastening nut of the fixing pin corresponding to the subsequent splice block to be installed can be unscrewed by using a tool such as a socket wrench, and then the fixing pin is moved to the side (namely the right side) far away from the first edge strip, so that an installation space is formed between the fixing pin corresponding to the splice block to be installed and the subsequent fixing pin, at the moment, the lower side of the splice block to be installed can be placed into the sliding long groove corresponding to the installation space, and then the splice block is righted, so that the upper side of the splice block is positioned in the installation space. When the splicing blocks needing to be installed transversely move and are installed in place, a fixing pin which is adjacent to the next splicing block is moved to the left side to a set position, and the fastening nut is screwed up to fix the fixing pin, so that the installation of the next splicing block can be started. Of course, corresponding positioning marks can be arranged on the upper connecting piece so as to facilitate accurate positioning of the fixing pins.
In order to enable adjacent splicing blocks to be reliably lapped, a splicing groove extending along the width direction (namely, transversely) of the splicing blocks can be arranged on a splicing inclined plane on one side of the splicing blocks, a connecting bulge is arranged on a splicing inclined plane on the other side of the splicing blocks, a splicing groove is arranged on a lapping inclined plane of a first edge strip, and a connecting bulge is arranged on a lapping inclined plane of a second edge strip.

That is to say, this scheme makes all splice to link into an organic whole, can avoid the rotation of any one of them splice and separate and produce the gap with between its adjacent splice.
Preferably, the length a of the clamping chute can be controlled in the following range: a is less than or equal to B/3. Therefore, when the splicing blocks are installed in place, the length of the clamping sliding groove is controlled to be less than one third of the width of the splicing blocks, and the fixing pin is eccentrically positioned on one side in the width direction of the splicing blocks. Like this, one side of each splice receives the location of fixed pin, and the opposite side receives the location of the connection arch of mutual joint and concatenation recess, has both been favorable to simplifying structure, easy to assemble, can ensure the reliable location of splice again, avoids forming the concatenation gap between the adjacent splice.
As another preferred scheme, a plurality of fixing pins corresponding to the splicing blocks can be respectively arranged on the upper connecting piece and the lower connecting piece, the clamping sliding grooves are respectively arranged on the upper side and the lower side of each splicing block, and the clamping sliding grooves extend to one side of the splicing blocks along the length direction to form the introducing ports. In step d and step e, the guide-in openings at the upper side and the lower side of the splicing block to be installed are directly opposite to the fixing pins corresponding to the upper connecting piece and the lower connecting piece, then the splicing block is moved, so that the corresponding fixing pins slide into the clamping sliding grooves of the splicing block through the guide-in openings until the fixing pins and the clamping sliding grooves form clamping.
It should be noted that, during installation, an included angle is formed between the splicing block to be installed and the width direction of the decorative wallboard, then the guide-in ports on the upper side and the lower side of the splicing block are opposite to the fixing pins corresponding to the upper connecting piece and the lower connecting piece, and the splicing block is moved. When the corresponding fixing pins slide into the clamping sliding grooves of the splicing blocks through the introducing ports, the splicing blocks can be rotated to the required direction, and then the splicing blocks move transversely until being installed in place. Thus, a large installation space does not need to be reserved when the splicing blocks are installed.
In order to facilitate clamping when the splicing installation is in place, as shown in fig. 6 and 7, the clamping sliding grooves on the splicing blocks can comprise sliding grooves 121 at the opening and clamping grooves 122 arranged at the bottoms of the sliding grooves, so that the cross sections of the clamping sliding grooves are stepped grooves with large openings and small bottoms. That is, the opening of the slide groove constitutes the opening of the catch slide. In addition, a rack 23 is arranged on one side of the inside of the clamping groove, which is far away from the leading-in port, the fixing pin comprises a fixing sleeve 313 with a cavity inside, a pin shaft vertically and rotatably arranged in the cavity of the fixing sleeve, and a circular supporting ring 314 arranged between the fixing sleeve and the pin shaft, the upper side of the fixing sleeve is fixedly connected to the upper connecting piece and movably located in the sliding groove, a gear 315 which can be meshed with the rack is arranged on the lower section of the pin shaft, which extends out of the fixing sleeve, and the inner hole of the fixing sleeve is a square hole, so that an annular space is formed between the square inner hole of the. The radial dimension of the annular space is the smallest at the middle position of the side wall of the inner hole of the fixing sleeve and the largest at the corner of the side wall of the inner hole of the fixing sleeve, so that a wedge-shaped space 316 with the radial dimension from small to large is formed between the interval from the middle of the side wall of the inner hole of the fixing sleeve to the corner and the outer peripheral surface of the pin shaft. In addition, 4 radial through holes which are uniformly distributed in the circumferential direction and have rectangular cross sections are arranged on the supporting ring, the radial through holes radially penetrate through the inner side wall and the outer side wall of the supporting ring, a locking cylinder 317 is arranged in each radial through hole, and the axial section shape of each locking cylinder is matched with the cross section shape of each radial through hole. In addition, the round pin epaxial pot head is equipped with torsional spring 318, and the one end of torsional spring is connected on the fixed cover, and the other end is connected on supporting the lasso, and the pretension elasticity of torsional spring forms the moment of torsion to supporting the lasso to make supporting the lasso and drive 4 locking cylinders and rotate, make the locking cylinder be located wedge space department, and the locking cylinder pastes the round pin axle outer peripheral face and fixed cover medial surface respectively. That is, when the maximum radial dimension at the apex is set to L1 and the minimum radial dimension at the middle position of the side length is L2, the diameter of the locking cylinder should be larger than L2 and smaller than L1.
In the step d and the step e, the introducing port of the clamping chute on one side of the splicing block is opposite to the fixing pin, then the splicing block is moved, so that the corresponding fixing pin slides into the clamping chute of the splicing block through the introducing port, the fixing sleeve of the fixing pin movably enters the sliding chute, and the lower part of the pin shaft of the fixing pin movably enters the clamping chute; when the fixed pin moves to the inside of the clamping sliding groove, the gear of the lower section of the pin shaft is meshed with the rack, so that the pin shaft is driven to rotate in the forward direction.
It will be appreciated that the locking cylinder is held in position approximately midway in the wedge-shaped space by the support collar under the torque of the torsion spring, with the inner side of the retaining sleeve engaging closely with the circumferential surface of the locking cylinder. When the pin shaft rotates forwards, the locking cylinder can be driven to roll towards one side of the maximum radial dimension by virtue of friction force, and the pin shaft can rotate smoothly at the moment; when the pin shaft rotates reversely, a tendency that the locking cylinder is driven to roll towards one side of the minimum radial dimension can be formed by means of friction force, and the locking cylinder cannot roll towards one side of the minimum radial dimension, so that the pressure of the locking cylinder, the pin shaft and the inner side surface of the fixed sleeve is correspondingly increased, and further the friction force is increased to form positive correlation. Through rationally setting the size of the inner hole of the fixed sleeve, the diameter of the pin shaft, the diameter of the locking cylinder and other sizes, the locking cylinder can conveniently form self-locking, thereby effectively preventing the reverse rotation of the pin shaft. Therefore, when the fixing pin enters the clamping sliding groove from the introducing port, the gear at the lower section of the pin shaft is meshed with the rack on one side inside the clamping groove, and the pin shaft is driven to rotate in the forward direction. When the splicing blocks are installed in place, the pin shafts are locked and cannot rotate reversely, so that the splicing blocks can be effectively prevented from moving reversely, and the splicing blocks are ensured to be clamped with the upper connecting strip and the lower connecting strip.
That is, one side of the decorative wall board formed by the above embodiments is connected with the wall surface, and the other side is in a suspended state. When we need to install the decorative wall board with both sides connected with the wall surface, as shown in fig. 8, the splicing groove on one side of the second edge strip away from the lapping inclined plane is a through hole which transversely penetrates through the lapping inclined plane, a locking pin 23 is movably arranged in the splicing groove, a connecting bulge of the side connecting piece connected with the second edge strip comprises a telescopic sleeve 52 arranged in the side connecting piece, a telescopic pin 53 capable of extending out of the surface of the side connecting piece is arranged in the telescopic sleeve, a pressure spring 54 abutting against the telescopic pin is arranged at the bottom of the telescopic sleeve, and the telescopic pin at the moment is in an extending state. After the installation method of the invention finishes the step f, a gap with a right trapezoid cross section is formed between the splicing inclined plane at the rear side of the Nth splicing plate and the surface of the side connecting piece, namely, the transverse size of one side of the gap is small, and the transverse size of the other side is large, at this time, the step g is as follows:
and putting a second edge strip into the gap from the side with the large transverse size, so that the lap joint inclined plane of the second edge strip is attached to the splicing inclined plane at the rear side of the Nth splicing plate, and then pressing the telescopic pin of the side connecting piece at the side with the small transverse size of the gap. When the second edge strip is installed in place in the gap, the pressure spring pushes the telescopic pin to extend outwards, so that the locking pin is pushed to move transversely in the locking through hole, the front end of the locking pin enters the splicing groove of the splicing inclined plane on the rear side of the Nth splicing plate, the front end of the telescopic pin enters the rear end of the locking through hole of the second edge strip, and then two sides of the second edge strip are respectively locked.
