The first embodiment is as shown in fig. 1, and the refrigeration house with the adjustable heat preservation effect comprises a storage space and an air conditioning system for regulating the temperature of the storage space. The storage space is enclosed by four side walls 1 and a top wall 11. The side wall 1 is formed by splicing a plurality of heat insulation plates 4.

When insulation is desired, the outer 415 and inner 411 conductor layers are insulated by outer soil insulation 414, inner soil insulation 412 and insulation plugs 4132 by moving the middle conductor layer 413 horizontally by the movement of the lever 44 to insulation plugs 4132 in a one-to-one correspondence between outer conductor heads 4151 and inner conductor heads 4111.
Referring to fig. 4, the hanging pin 5 includes a pointed head 51, an accommodating through hole 52 and a hanging section 53, which are sequentially arranged.
Two arresting bars 2 are accommodated in the accommodating through-hole 52. The middle parts of the two arresting bars 2 are connected together by a hinge pin 21. Both ends of the hinge pin 21 are connected to both side walls of the receiving through hole 52. The arresting bar 3 is prismatic. The two sides of the arresting bar 2 along the rotation direction of the arresting bar are provided with edges 22.
The two arresting bars 2 are respectively a first arresting bar 2-1 and a second arresting bar 2-2. The first barrier bar 2-1 comprises a middle section 2-11 and two edge sections 2-12. Both ends of the middle section 2-11 are provided with insertion holes 2-111 extending circumferentially along the hinge pin 21 and penetrating the middle section. The two end faces of the middle section 2-11 are provided with connecting holes 2-112. The connection holes 2-112 communicate with the insertion holes 2-111 located at the same end as the connection holes. One end of the edge section 2-12 is provided with a connector 2-121, and the other end is provided with a sharp head 2-122. The two edge sections 2-12 are correspondingly inserted into the connecting holes 2-112 at the two ends of the middle section 2-11 one by one through the connectors 2-121 and connected with the two ends of the middle section 2-11.

A threaded mandril 3 is connected with the internal thread of the internal thread hole 531. The axis of the threaded carrier rod 3 perpendicularly intersects the axis of the hinge pin 21. The hinge pin 21 is aligned with both arresting bars 2. One end of the threaded mandril 3 is rotatably connected with the jacking block 31, and the other end is provided with a straight groove 32. The top block 31 is located in the accommodating through hole 52. The threaded jack rod 3 drives the arresting bar 2 via the jack block 31. The linear groove 32 is used for inserting the head of a linear screwdriver when the threaded mandril 3 is rotated.
Referring to fig. 5, the crush boxes 2-21 and the second bars 2-2 form escape gaps 2-22 between them through which the first bars 2-1 pass. The insertion hole 2-111 and the pressing block 2-21 are located on the same plane perpendicular to the hinge pin 21. The insertion holes 2-111 and the pressing blocks 2-21 are aligned along the circumference of the hinge pin 21.
Referring to fig. 2 to 5, the method of mounting the hanger pin to the plate body is: the stopping pin 2 is firstly rotated and folded to be completely accommodated in the accommodating through hole 52, then the pointed head 51 faces the heat insulation board and the end part of the hanging object section 53 is knocked to pin the hanging object into the heat insulation board, and the nailing depth is determined by the fact that the nailing depth does not extend into the cavity 416. And then the threaded mandril 3 is rotated to increase the length of the threaded mandril extending into the accommodating through hole, the threaded mandril 3 drives the jacking block 31 to be inserted between the two blocking rods 2 so that the two blocking rods rotate and separate by taking the hinge pin 21 as an axis, and the separating result is that the blocking rods extend out of the accommodating through hole 52 and are inserted into the inner soil heat-insulating layer 412 along the plane direction of the heat-insulating plate, so that the resistance when the hanging pin is pulled out is increased, and the hanging pin is not easy to be pulled out. When the threaded mandril 3 drives the first arresting bar 2-1 and the second arresting bar 2-2 to rotate and separate, the depth of the extrusion block 2-21 inserted into the insertion hole 2-111 becomes deeper gradually, and the end surface 2-214 of the extrusion block far away from the hinge pin is abutted to the connecting head 2-121 so as to be ejected out of the middle section 2-11 through the edge section 2-12 (namely, the first arresting bar 2-1 is lengthened), thereby playing a role in improving the clamping effect. When the screwed length of the threaded ejector rod 3 reaches the maximum value, the extending length of the arresting rod 2 reaches the maximum value, and at the moment, both ends of the arresting rod extend out of the accommodating through holes by 3 cm.
The second embodiment is different from the first embodiment in that:
referring to fig. 6, the threaded mandril 3 is provided with a stringing hole 33. The rope threading hole 33 extends along the axial direction of the threaded mandril 3 and penetrates through the jacking block 31. The two arresting bars 2 are connected with the ropes 34. The iron cable 34 passes through the threaded mandril 3 through the rope-passing hole 33 and is led out from the object hanging section 53.
