[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0021] like Figure 1-4As shown, a heat insulation board that is easy to splice includes a hard board 1, a heat insulation board body 2 and a connecting piece 6. One side of the hard board 1 is fixedly connected to the heat insulation board body 2, and the other side of the hard board 1 is provided with mounting grooves 3 at four corners, and one end of the mounting groove 3 is provided with a limiting groove 4. Both ends of the connecting piece 6 are fixedly connected to the limiting piece 7, and the connecting piece 6 is adapted to the mounting groove 3, and the limiting piece 7 is adapted to the limiting groove 4. The connecting piece 6 and the limiting piece 7 are arranged on the hard board 1 through fasteners 5.

[0022] Specifically, the material of the hard board 1 is asbestos board, hard polyurethane board, rock wool insulation board or glass wool insulation board, which can ensure the hardness of the hard board 1 and also have heat insulation performance. The connecting piece 6 and the limiting piece 7 are fastened by the fastener 5, and then the connecting piece 6 and the limiting piece 7 are fastened to another insulation board to make the two insulation boards spliced. At the same time, the limiting piece 7 is located in the limiting groove 4, so that the connecting piece 6 and the limiting piece 7 cooperate to limit the two hard boards 1 to avoid gaps between the two hard boards 1.

[0023] like Figure 2 As shown, two mounting grooves 3 are arranged at four corners of the hard board 1, and the two mounting grooves 3 are perpendicular to each other.

[0024] Specifically, when a plurality of heat insulation boards are connected, the connecting piece 6 and the limiting piece 7 can be placed in the installation groove 3 and the limiting groove 4, so that the plurality of heat insulation boards are firmly connected.

[0025] like Figure 1 As shown, the connecting piece 6 and the limiting piece 7 are an integrally formed structure, and are provided with a mounting hole 8 for the fastener 5 to pass through.

[0026] Specifically, the integrated structure makes the connecting piece 6 and the limiting piece 7 structurally stable, thus ensuring the stability of the connection.

[0027] like Figure 2 As shown, the fastener 5 includes a screw rod 51 and a nut 52 . The screw rod 51 is fixedly connected to the hard board 1 , and the nut 52 is threadedly connected to the screw rod 51 .

[0028] Specifically, the connecting piece 6 is placed in the mounting groove 3, and the two screws 51 on the two boards pass through the two mounting holes 8 on the connecting piece 6 at the same time, and then the two nuts 52 are screwed onto the screws 51 one by one, so as to tighten the connecting piece 6, and thus splice two or more adjacent insulation boards. If splicing is not required, the screw 51 is passed through the mounting hole 8 at one end of the connecting piece 6, and then the nut 52 is screwed to tighten it, and the other end is fastened to the equipment by other fastening measures, so it can also be used alone.

[0029] like Figure 4As shown, the insulation board body 2 is a multi-layer structure, which includes an infrared reflective coating 9, a ceramic fiber layer 10, a double-sided smooth aluminum foil layer 11, a foam metal layer 12 and a high-temperature resistant insulation coating 13 in sequence, and the infrared reflective coating 9 is fixedly connected to the hard board 1 on one side away from the ceramic fiber layer 10, and the multi-layer insulation can ensure the insulation performance.

[0030] In the above structure, thermal insulation can be achieved by attaching the insulation board body 2 to the equipment to be insulated, and the insulation board is fixed to the equipment by passing the fastener 5 through the mounting hole 8. If multiple pieces need to be spliced, the connecting piece 6 is placed in the mounting groove 3, and the two screws 51 on the two boards are passed through the two mounting holes 8 on the connecting piece 6 at the same time, and then the two nuts 52 are screwed onto the screws 51 one by one, so as to tighten the connecting piece 6, thereby splicing two adjacent insulation boards, which is more convenient for splicing.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments.
