DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 An environmentally friendly low-density metal-faced rigid polyurethane sandwich panel comprises: a polyurethane sandwich panel body 1 and a splicing mechanism 2, wherein the splicing mechanism 2 is arranged on the polyurethane sandwich panel body 1, and the splicing mechanism 2 comprises a positioning groove 21 and a positioning block 22, wherein the positioning groove 21 is arranged on the right side of the top of the polyurethane sandwich panel body 1, and the positioning block 22 is installed on the left side of the polyurethane sandwich panel body 1 and corresponds to the position of the positioning groove 21.

[0019] The limiting fixing mechanism 3 is arranged on the positioning groove 21. The limiting fixing mechanism 3 includes a slot 31, which is opened at the bottom of the inner wall of the positioning groove 21. The bottom of the positioning block 22 and the position corresponding to the slot 31 are fixedly connected with an insert block 32 adapted to the slot 31. A connecting groove 33 is opened on the left side of the slot 31 and is interconnected with the slot 31. A fixing groove 34 is opened on the left side of the connecting groove 33 and is interconnected with the slot 31. Two fixing rods 35 are fixedly connected to the left side of the inner wall of the fixing groove 34. The right end of the fixing rod 35 is fixedly connected to the right side of the inner wall of the fixing groove 34. The surfaces of the two fixing rods 35 slide through the movable block 36. The surface of the movable block 36 is in sliding contact with the inner wall of the fixed groove 34. The surface of the fixed rod 35 is sleeved with an elastic member 37, and the elastic member 37 is made of a spring. The right side of the movable block 36 is fixedly connected with a connecting block 38. The right side of the connecting block 38 passes through the fixed groove 34 and the connecting groove 33 from left to right in sequence and extends to the inside of the connecting groove 33. The right side of the connecting block 38 is fixedly connected with a limiting block 39. The right side of the limiting block 39 passes through the connecting groove 33 and the slot 31 from left to right in sequence and extends to the inside of the slot 31. A limiting groove 310 adapted to the limiting block 39 is provided on the left side of the insert block 32 and at the position corresponding to the limiting block 39.

[0020] Through the mutual cooperation of the positioning groove 21, the positioning block 22, the slot 31, the insert block 32, the connecting groove 33, the fixing groove 34, the fixing rod 35, the movable block 36, the elastic member 37, the connecting block 38, the limiting block 39 and the limiting groove 310, it is convenient to splice and fix two adjacent environmentally friendly low-density metal-faced rigid polyurethane sandwich panels, thereby ensuring the stability after splicing and fixing, avoiding the phenomenon of looseness after splicing, and the splicing process is simple and convenient, thereby improving practicality.

[0021] When in use, another polyurethane sandwich panel body 1 drives the positioning block 22 to be inserted into the positioning groove 21, so that the insert block 32 is inserted into the slot 31. When the insert block 32 and the limit block 39 come into contact, the insert block 32 squeezes the limit block 39 to move to the left. The limit block 39 drives the movable block 36 to move to the left through the connecting block 38. The movable block 36 squeezes the elastic member 37 to move, so that the limit block 39 moves to the inside of the connecting groove 33. When the insert block 32 drives the limit groove 310 downward and overlaps with the limit block 39, the elastic member 37 drives the movable block 36 to move to the right through the restoring elastic force of the elastic member 37. The movable block 36 drives the limit block 39 to move to the right through the connecting block 38, so that the limit block 39 is inserted into the limit groove 310 to complete the splicing.
