DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0027] Embodiment 1

[0028] As Figures 1 to 7As shown, a spliced wear-resistant composite plate includes a steel plate layer 1 and a wear-resistant layer 2, wherein there are splicing grooves 3 and splicing rods 4 on the steel plate layer 1, the splicing groove 3 is a rectangular groove extending from the edge of the bottom surface of the steel plate layer 1 towards the wear-resistant layer 2, the middle part of the groove wall surface of the splicing groove 3 has a vertically protruding protruding strip facing each other, the splicing rod 4 is a rectangular straight rod extending from the edge of the bottom surface of the steel plate layer 1 towards the wear-resistant layer 2, the middle part of the two side surfaces of the splicing rod 4 has a vertically recessed groove recessed inward, the splicing rod 4 has a positioning convex ball, the positioning convex ball is a spherical convex particle protruding outward from the outer side surface of the splicing rod 4, the splicing groove 3 has an embedded ball groove, the embedded ball groove is an arc-shaped recessed groove recessed inward from the inner side surface of the splicing groove 3. The wear-resistant layer 2 is a complete rectangular shape, the splicing grooves 3 and the splicing rods 4 are distributed on the steel plate layer 1, wherein the splicing grooves 3 are arranged on one pair of adjacent sides at the same time, the splicing rods 4 are arranged on the other pair of adjacent sides at the same time, so that the composite plate can be spliced continuously until the required length or size is reached, and the protruding splicing rods 4 around are cut off according to the actual situation. When splicing two composite plates, the splicing groove 3 of one composite plate can be aligned with the splicing rod 4 of the other composite plate from above, and then pressed down so that the splicing rod 4 is inserted into the splicing groove 3, at the same time, the vertically recessed groove cooperates with the vertically protruding protruding strip to avoid the inclination and tilting of the composite plate, especially when the splicing rod 4 is completely inserted into the splicing groove 3, the spherical convex particle will enter the embedded ball groove to prevent the two composite plates from separating, wherein the spherical convex particle and the embedded ball groove can be arranged above the splicing rod 4 and the splicing groove 3 respectively. The spliced wear-resistant composite plate has the benefit of efficient replacement, the part that is not seriously worn can be reused, only the part that is seriously worn is replaced, and the utilization rate of materials is improved.

[0029] It also includes a self-locking part that increases the firmness between the composite plates.

[0030] The self-locking part comprises a horizontal sliding groove 5, a sliding lock plate, a pushing rod 6, an expansion groove 7 and a locking groove 8. The expansion groove 7 is a vertical recessed groove extending inward from the inner side groove wall of the self-splicing groove 3. The horizontal sliding groove 5 is a groove extending horizontally and inward to the inner side of the expansion groove 7, which communicates with the two splicing grooves 3. The sliding lock plate comprises a regular block 9 and an inclined pressing rod 10. The regular block 9 is a rectangular panel. The inclined pressing rod 10 extends outward and obliquely from the middle of the side of the regular block 9 to the extension line of the long side of the regular block 9. The pushing rod 6 is a straight rod extending obliquely downward from the middle of the vertical edge of the outer side of the splicing rod 4 inserted into the splicing groove 3 on one side of the expansion groove 7. The pushing rod 6 is in the same plane as the expansion groove 7. The locking groove 8 is a recessed groove with gradually decreasing thickness inward from the side of the splicing rod 4 on the side other than the side of the pushing rod 6. The sliding lock plate is pushed into the horizontal sliding groove 5, wherein the side of the inclined pressing rod 10 is close to the splicing groove 3 on the side of the expansion groove 7. At this time, the two composite boards are spliced. When the splicing rod 4 enters the splicing groove 3, the pushing rod 6 enters the expansion groove 7 at the same time. With the deepening, the pushing rod 6 will extrude the inclined pressing rod 10, pushing the regular block 9 to move in the horizontal sliding groove 5 to the splicing groove 3 on the other side until the pushing rod 6 completely extrudes the inclined pressing rod 10. The distal end of the regular block 9 is inserted into the locking groove 8 which is aligned with the rising of the splicing rod 4 on the other side. The locking groove 8 gradually decreases in thickness for matching the gradually inserted regular block 9, realizing the self-locking of the two composite boards. Since the splicing rod 4 is limited by the sliding lock plate and cannot move in the splicing groove 3, the pushing rod 6 cannot move because it is in contact with the position of the inclined pressing rod 10. Therefore, the sliding lock plate cannot move, realizing self-locking and improving the firmness of the spliced composite boards.

[0031] It also includes a reinforcing strip 11 to improve the bending resistance.

[0032] The reinforcing strip 11 is a straight rod extending horizontally and outward from the side edge of the splicing rod 4 where the pushing rod 6 is located. As the splicing rod 4 enters the splicing groove 3, the outer end of the reinforcing strip 11 will be in contact with the groove surface of the expansion groove 7. If the spliced two composite boards are bent by external force, the reinforcing strip 11 can be in contact with the groove surface of the expansion groove 7, reducing the extrusion of the pushing rod 6 by bending and preventing structural damage, thereby destroying the self-locking structure.

[0033] The outer end of the reinforcing strip 11 is a convex cylindrical arc surface.

[0034] There is a stress groove 12 on the outer end of the reinforcing strip 11. The stress groove 12 is a recessed rectangular groove distributed on both sides of the top of the cylindrical arc surface. When the stress groove 12 is extruded and rotated on the top of the outer end of the reinforcing strip 11, it can increase the contact roughness and prevent the reinforcing strip 11 from slipping on the groove surface of the expansion groove 7.

[0035] The steel plate layer 1 also has a regulating groove, which includes a through groove and a spreading groove, the through groove is a straight-through groove penetrating through both sides of the groove surface of the steel plate layer 1, and the spreading groove is a straight groove extending outward from both sides of the through groove. The wear-resistant layer 2 will have a whole or partial sharp temperature rise under a large-area wear working condition, and the regulating liquid can be passed into the regulating groove to alleviate the temperature rise condition, and in particular, the shrinkage condition of the splicing part can be changed when the composite plate is replaced, so as to facilitate disassembly.
