[0002] The insulation door is an energy-saving and environmentally friendly door that can well control the indoor temperature. The thickness of the insulation material can be determined according to the needs of the project. At present, the most commonly used insulation doors on the market are sliding opening and closing and door leaf opening and closing. The sliding insulation door needs to use a longer top frame slideway, and the door leaf opening and closing needs to occupy a large space, which is inconvenient to use. According to the Chinese utility model patent (application number: 201921623004.X), an insulation door is disclosed. The utility model discloses an automatic insulation door for a greenhouse, including a door panel, a door frame, and a door handle. It is characterized in that it also includes a driving telescopic rod, a driving shaft, a connecting rod, and an electric control box. The inner and outer surfaces of the door panel are provided with a touch switch. The door panel is provided with a vacuum pressure-resistant layer, an insulation layer, a moisture-proof sealing layer, and a stainless steel outer layer from the inside to the outside; the automatic insulation door for a greenhouse disclosed by the utility model has a simple structure and a reasonable design. On the basis of the existing greenhouse, it can be realized through modification and installation, which not only improves the insulation effect of the insulation door, but also frees both hands, and is convenient for easily opening and closing the greenhouse door when carrying objects.

DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] like Figure 1-Figure 6 As shown, the thermal insulation door provided in this embodiment includes a door frame 1, the inner side of the door frame 1 is connected to a first door body 2 by a hinge, one side of the first door body 2 is connected to a second door body 3 by a hinge, and an electric telescopic rod 4 is connected between the door frame 1 and the second door body 3; limiting grooves 5 are symmetrically provided at the top and bottom of the door frame 1, and universal wheels 6 that cooperate with the limiting grooves 5 are symmetrically rotatably installed at the top and bottom of the second door body 3, a locking block 7 is slidably installed on the inner side of the door frame 1, and an insert block 8 that cooperates with the locking block 7 is fixedly connected to one side of the second door body 3.

[0027] By setting the door frame 1, the first door body 2 and the second door body 3, the first door body 2 and the second door body 3 are connected by hinges, so the first door body 2 and the second door body 3 can be folded together. Compared with a single door, the space occupied and the space required for opening and closing the door are relatively small, which is suitable for use in a greenhouse with a small activity space in front of the door; through the limiting groove 5 and the universal wheel 6, the universal wheel 6 is installed at the top and bottom of the second door body 3, and slides with the limiting groove 5, one side of the first door body 2 and the second door body 3 is supported by the side wall of the door frame 1 through the hinge, and the bottom of the first door body 2 and the second door body 3 is supported by the bottom limiting groove 5 of the door frame 1, and the weight is dispersed, so it is not easy to be damaged; by the setting of the locking block 7 and the inserting block 8, when the power is off, the first door body 2 and the second door body 3 are manually pushed so that the inserting block 8 is restricted by the locking block 7 to achieve closing, which can prevent the situation where the first door body 2 and the second door body 3 cannot be completely closed and cannot keep warm when the power is off.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 5 As shown, a mounting plate 101 rotatably connected to the electric telescopic rod 4 is fixedly installed on the front of the door frame 1, a rotating block 301 is fixedly installed on the front of the second door body 3, a handle 302 located on one side of the rotating block 301 is fixedly connected to the front of the second door body 3, and mounting holes 303 cooperating with the universal wheel 6 are provided at the top and bottom of the second door body 3.

[0029] By setting the mounting plate 101 and the rotating block 301, bolts are used to connect the bottom of the electric telescopic rod 4 to the mounting plate 101, and bolts are used to connect the top of the electric telescopic rod 4 to the rotating block 301, so that the electric telescopic rod 4 can rotate relative to the door frame 1 and the second door body 3; the handle 302 is set to facilitate opening and closing.

[0030] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, a slot 102 cooperating with the insert block 8 is provided on the inner wall of the door frame 1 , and a slide groove 103 cooperating with the lock block 7 is provided on the top of the slot 102 .

[0031] Through the setting of the slot 102 , the insertion block 8 into the slot 102 can prevent the second door body 3 from continuing to rotate. Through the setting of the slide groove 103 , the locking block 7 can slide up and down in the slide groove 103 to lock the insertion block 8 .

[0032] In this embodiment, if Figure 1 , Figure 4 and Figure 6As shown, a limiting hole 104 is provided at the top of the slide groove 103, a sliding hole 105 penetrating the door frame 1 is provided at the front of the slide groove 103, a nut groove 106 is provided at the top of the sliding hole 105, a maintenance groove 107 is provided at the top of the nut groove 106, a sliding rod 701 that slides with the limiting hole 104 is fixedly connected to the top of the lock block 7, a lever 704 that slides with the sliding hole 105 is fixedly connected to the front of the lock block 7, a spring 702 is sleeved on the outer side of the sliding rod 701, a nut 703 is threadedly connected to the top of the sliding rod 701, and a slope is provided at the bottom of the lock block 7.

[0033] Through the setting of the slide rod 701 and the limiting hole 104, the lock block 7 can only move up and down. When installing the lock block 7, first hold the lever 704 and slide it on the slide hole 105, so that the top of the slide rod 701 enters the maintenance groove 107. After installing the nut 703, release the lever 704. Under the action of the spring 702, the nut 703 shrinks into the nut groove 106. At this time, the bottom slope of the lock block 7 is located in the slot 102. When closing the door, the insertion block 8 squeezes the slope at the bottom of the lock block 7 to make the lock block 7 move up and compress the spring 702 to lock the door. When the door needs to be opened, move the lever 704 up to unlock and open the door.

[0034] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a thermal insulation door provided in this embodiment is as follows:

[0035] Step 1: When opening the door, the electric telescopic rod 4 pulls the second door body 3, at which time the first door body 2 and the second door body 3 are folded with each other, and the universal wheel 6 moves in the limiting groove 5;

[0036] Step 2: When closing the door, the electric telescopic rod 4 pushes the second door body 3, and the first door body 2 and the second door body 3 folded together move away from each other and finally close;

[0037] Step 3: When the power is off, slide the lever 704 and pull the handle 302 to manually switch on and off.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
