Description

TECHNICAL FIELD

[0001] The present application relates to the field of isolation experimental devices, in particular to a laboratory isolation door. BACKGROUND

[0002] At present, many models used in aviation and aerospace need to be verified for low-temperature performance under normal pressure and dry air. The low-temperature performance verification of these models is usually carried out in a special variable-temperature laboratory. Because the space in the laboratory is relatively large, it takes a long time to heat and cool the entire laboratory, and the energy consumption is also relatively large. Therefore, the laboratory space is usually divided to form a separate small room, i.e., a rapid temperature changing room, so that the key parts of the experimental model can be placed in the rapid temperature changing room for operation. At this time, an isolation door needs to be set up. When the isolation door is closed, the rapid temperature changing room can be quickly heated and cooled, so that personnel can enter without affecting other parts of the laboratory.

[0003] In some related technologies, the models for low-temperature experiments are usually of two types, i.e., with a support rod and without a support rod. That is, the isolation door has two corresponding states. The first type of isolation door is provided with a support rod hole through which the support rod can pass. The second type of isolation door is not provided with a support rod hole.

[0004] (1) When experimental personnel enter the laboratory to replace the experimental model, the isolation door with the support rod hole cannot automatically seal the support rod hole, causing the air in the laboratory to diffuse, changing the temperature in the laboratory, and when the isolation door cannot be sealed, the cold air in the laboratory diffuses, which can freeze the operator.

[0005] (2) When the two types of models with and without support rods are subjected to low-temperature experiments, different isolation doors need to be matched for use. Therefore, an isolation door that can be used for both types of models is needed to facilitate the experiment. SUMMARY

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] The embodiment of the present application provides an isolation door for a laboratory, to solve the problem that the isolation door with the supporting rod hole cannot be automatically sealed when the model is replaced in the related technology.

[0052] Please refer to Figure 2 , Figure 3 and Figure 5The utility model provides a laboratory isolation door, including isolation door main body 1, bracket 2 and sealing slider 3,

[0053] Wherein isolation door main body 1 is equipped with support rod hole 10, support rod hole 10 is used to pass through the model with support rod of being carried out variable temperature laboratory;Bracket 2 is connected and is arranged on isolation door main body 1;Sealing slider 3 is movably arranged on bracket 2, and sealing slider 3 moves along bracket 2 under the action of gravity and covers and seals support rod hole 10.

[0054] In use, on the one hand, the support rod part of the model with the support rod is arranged in the support rod hole 10 and placed in the variable temperature laboratory for experiment, the sealing slider 3 is arranged on the bracket 2, and the sealing slider 3 is in contact with the support rod under the action of gravity, and at this time, the support rod plays a role in limiting the falling of the sealing slider 3.

[0055] When the support rod is taken out of the support rod hole 10, the sealing slider 3 falls in the bracket 2 under the action of its own gravity due to the loss of the limiting abutment of the support rod, thereby sealing the support rod hole 10. When the sealing slider 3 moves along the bracket 2, it is in contact with the isolation door main body 1, thereby sealing the support rod hole 10, preventing the cold air in the laboratory from spreading, preventing the operator from being frozen, and preventing the temperature in the laboratory from changing and destroying the dry environment of the laboratory.

[0056] On the other hand, when the model without the support rod is experimented and the laboratory needs to be closed, the sealing slider 3 seals the support rod hole 10 under the action of gravity, and at this time, the isolation door main body 1 is closed, which is equivalent to the isolation door without the support rod hole 10, so that the isolation door can be used for the model experiment with or without the support rod.

[0057] In some preferred embodiments, the above isolation door main body 1 can be a single whole door or a double-opening door, and the automatic sealing effect of the above bracket 2 and sealing slider 3 is suitable for the single whole door or the double-opening door.

[0058] For example, the bracket 2 is vertically arranged and located around the support rod hole 10, and the sealing slider 3 falls to cover and seal the corresponding support rod hole 10.

[0059] As shown in Figure 2 , Figure 3 , Figure 5 and Figure 6 , the isolation door main body 1 includes two closable sub-isolation doors 11, and the sub-isolation doors 11 are provided with sub-support rod holes, and the sub-support rod holes of the two sub-isolation doors can be combined to form the above-mentioned support rod hole 10.

[0060] Each of the sub-isolation doors 11 is provided with a bracket 2, and each bracket 2 is provided with a sealing sliding block 3, wherein the sealing sliding block 3 and the support rod hole 10 are arranged as follows:

[0061] The moving track of the corresponding sealing sliding block 3 on one of the sub-isolation doors 11 on the bracket 2 covers part of the support rod hole 10, and the moving track of the corresponding sealing sliding block 3 on the other sub-isolation door 11 covers the remaining part of the support rod hole 10, so that the left and right sealing sliding blocks 3 seal the support rod hole 10.

[0062] Further, the bracket 2 has the following two forms:

[0063] Firstly, the bracket 2 is vertically arranged, and the brackets 2 on each of the sub-isolation doors 11 are arranged in parallel, and the sealing sliding block 3 on each bracket 2 moves in the vertical direction along the bracket 2 under the action of gravity, and this form ensures that the sealing sliding block 3 slides on the bracket 2 and does not fall off.

[0064] Secondly, the bracket 2 is arranged in an inclined manner, and the brackets 2 on the two sub-isolation doors 11 are arranged in a symmetrical manner, and the sealing sliding block 3 on each bracket 2 slides downwardly along the bracket 2 under the action of gravity, and this form uses the inclined sliding manner to make the sealing sliding blocks 3 on the two brackets 2 abut against each other when sealing the support rod hole 10, that is, the abutting connection of the two sealing sliding blocks 3 abut against each other, and the gravity makes the connection between the two sealing sliding blocks 3 more compact, thereby enhancing the sealing performance, and this form ensures that the sealing sliding block 3 slides on the bracket 2 and does not fall off.

[0065] Further, in order to make the sealing sliding block 3 move more stably on the sub-isolation door 11 and not easy to fall off, the number of brackets 2 is set to two, and the two brackets 2 are arranged in parallel and at intervals, and the two brackets 2 form a sliding space for accommodating the sealing sliding block 3, so that the sealing sliding block 3 moves in the sliding space, and the moving track of the sealing sliding block 3 is defined, and the sealing sliding block 3 is limited in the sliding space;

[0066] Among them, the two brackets 2 are arranged in parallel and at intervals, and correspondingly have the above-mentioned two forms of inclined arrangement and vertical arrangement of the bracket 2; in the vertical state, the two brackets are located above the support rod hole 10, the sealing sliding block 3 on the bracket 2 slides downwardly in the vertical direction, and part of the sealing sliding block 3 extends out of the bracket 2, and the two sealing sliding blocks 3 cover and seal the support rod hole 10, and in this form, when opening and placing, an external force is needed to lift the sealing sliding block 3 upwardly to place it into the support rod hole 10;

[0067] In the inclined state, the two brackets 2 are arranged as follows: Figure 2As shown, two brackets 2 in such an inclined state do not need external force to lift the sealing slider 3 when the model with the support rod is tested and the door is closed. During the process of closing the door, the model with the support rod is placed between the two sub-isolation doors 11. As the gap between the sub-isolation doors 11 becomes smaller, the support rod and the sealing slider 3 come into contact and push the sealing slider 3 away to both sides, finally achieving the sealing of the sub-isolation doors 11. This mode mainly considers that in low temperature, lifting the sealing slider 3 in the vertical structure of the bracket 2 will cause damage to the operator, such as frostbite, etc.

[0068] As shown in the drawings, Figure 5 In some preferred embodiments, in order to simplify the structure and make the sealing slider 3 slide downward under the action of gravity, and cooperate with the inclined state of the bracket 2, the bracket 2 is set as follows:

[0069] The bracket 2 comprises a guide slide plate 20 and a limiting part 21 arranged on the guide slide plate 20. The guide slide plate 20 is arranged on the sub-isolation door 11, and the sealing slider 3 moves along the guide slide plate 20. The limiting part 21 is used to prevent the sealing slider 3 from falling off the guide slide plate 20;

[0070] The limiting part 21 comprises a first limiting part 210 and a second limiting part 211, which limit from different aspects respectively; such a form can

[0071] The first limiting part 210 is arranged at the position relatively lower of the two ends of the guide slide plate 20, which is used to prevent the sealing slider 3 from falling off the bottom of the guide slide plate 20 due to its own weight. This is the structure in the form of the inclined bracket 2;

[0072] The second limiting part 211 is arranged on the side of the guide slide plate 20 away from the sub-isolation door 11, which is used to prevent the sealing slider 3 from falling off laterally during the movement along the guide slide plate 20, thereby achieving the purpose of preventing the sealing slider 3 from falling off. In this embodiment, the two guide slide plates 20 are arranged in parallel and spaced apart, and the second limiting parts 211 are arranged oppositely. The guide slide plate 20, the second limiting part 211 and the first limiting part 210 form the above-mentioned sliding space.

[0073] Further, as shown in the drawings, Figure 6 At the joint of each bracket 2, a labyrinth seal is formed to reduce air convection. The sealing slider 3 is a special-shaped plate, which can be made of low-temperature-resistant and heat-insulating materials such as glass steel with large density, so as to facilitate heat insulation and sliding under its own weight.

[0074] Further, the sealing between the support rod and the isolation door main body 1 is strengthened. The sub-isolation door 11 is a welded part, and a low-temperature-resistant soft material is arranged at the joint of the sub-isolation door 11 and in the sub-support rod hole. When the door is closed, the soft material is compressed, and the sub-isolation doors 11 can be simply sealed.

[0075] Further, in order to strengthen the connection between the guide slide plate 20 and the sub-isolation door 11, and to apply the weight of the sealing slide block 3 and cooperate with the sliding of the sealing slide block 3, an L-shaped connecting part 22 is arranged, and the upper and lower connecting parts 22 are arranged opposite to each other, and a small gap is arranged between the upper and lower ends of the sealing slide block 3, which can generate a large resistance to air and achieve simple sealing of the normal pressure gas.

[0076] Through the above sealing arrangement, the sealing effect of the isolation door body 1 is enhanced, and the rapid temperature changing chamber is isolated, and the rapid temperature rising and falling operation can be carried out separately in order to process and observe the experimental model

[0077] Please refer to Figures 1-10 In order to apply the above isolation door body 1, realize the opening and closing of the door and sealing, the following settings are made:

[0078] Further comprising an upper track assembly 4, the upper track assembly 4 is slidably connected with the top of the isolation door body 1 and is used to be connected to the wall plate 8;

[0079] A lower track assembly 5 is slidably connected with the bottom of the isolation door body 1 and is used to be connected to the wall plate 8;

[0080] A sealing structure is arranged between the isolation door body 1 and the wall plate 8, which is used to seal the isolation door body 1 and the wall plate 8;

[0081] A driving device 7 is connected with the isolation door body 1 and is used to drive the isolation door body 1 to move along the upper track assembly 4 and the lower track assembly 5, realize linear reciprocating motion, so that the isolation door body 1 can seal the hole of the wall plate 8.

[0082] The lower track assembly 5 includes a support frame and a slide rail, and the slide rail is made of a material with low temperature resistance and low friction coefficient, such as high molecular weight polyethylene. The support frame is a welded part welded to the wall plate 8, and the support frame is rigidly fixed with the slide rail. The structure at the bottom of the isolation door body 1 clamps the slide rail, and the isolation door body 1 slides between the slide rails.

[0083] The upper track assembly 4 includes a hanging part 41 and a sliding part 42, the hanging part 41 is provided with a sliding groove and is connected with the wall plate 8, and the hanging part 41 is arranged in parallel with the slide rail of the lower track assembly 5; the sliding part 42 has a mounting part 420 and a sliding part 421 connected with each other, the mounting part 420 is connected with the isolation door body 1, and the sliding part 421 is slidably arranged in the sliding groove; the sliding part 42 moves along the sliding groove in the hanging part 41, which ensures the linear movement of the sliding part 42, and the sliding part 42 is connected with the isolation door body 1.

[0084] The driving shaft of the driving device 7 is connected with the isolation door body 1, and the isolation door body 1 moves linearly along the slide rail and the hanging member 41 of the lower rail assembly 5 to realize opening and closing of the door.

[0085] As shown in Figure 7 and Figure 8 , the sealing structure comprises a sealing frame 6 and a sealing strip 9; the sealing frame 6 is fixedly connected to the wall plate 8 and used for filling the gap between the isolation door body 1 and the wall plate 8; and the sealing strip 9 is connected to the isolation door body 1 and used for sealing the gap between the sealing frame 6 and the isolation door body 1 to separate the space on both sides (in the thickness direction) of the rapid temperature changing room.

[0086] Specifically, the sealing frame 6 is fixedly connected to the wall plate 8, the sealing frame 6 is arranged around the hole of the wall plate 8 and is rigidly fixed (screwed) to the wall plate 8, and the sealing frame 6 is made of a material with low friction coefficient and low temperature resistance, such as high molecular weight polyethylene. When the isolation door is closed, the sealing strip 9 is pressed against the side of the sealing frame 6 to achieve sealing around the hole.

[0087] The sealing strip 9 is an integral structure and is fixed to the top, bottom and outer side of the isolation door body 1 by screws. The specific structure of the sealing strip 9 comprises a profiled plate 90 provided with a receiving space and connected to the isolation door body 1 on one side, and a sealing sheet 91 arranged in the receiving space on one side and abutting against the sealing frame 6 on the other side. The sealing sheet 91 is a sealing sheet with low friction coefficient and low temperature resistance, such as a polytetrafluoroethylene sheet. The profiled plate 90 is a profiled steel plate approximately in the shape of C, facilitating the formation of an inner buckle. When the isolation door body 1 contacts the sealing frame 6, the sealing sheet 91 is pressed and tightly attached to the sealing frame 6.

[0088] The above-mentioned materials are conventional materials and easy to purchase, and the structure is simple, so that the isolation door in the application only needs to be installed once, the driving is simple, the operation is simple, and the control is easy.

[0089] Principle of the application:

[0090] (1) Experiment model without support rod

[0091] ①The driving device 7 drives the isolation door body 1 to open, and the experiment model is loaded into the rapid temperature changing room;

[0092] ②The driving device 7 drives the isolation door body 1 to close, and the isolation door body 1 moves linearly along the slide rail and the hanging member 41 of the lower rail assembly 5 until reaching the closed position, the two sub-isolation doors 11 contact, and the sealing material in the middle of the door is pressed. At this time, the sealing slide block 3 remains in the lowest position under the action of gravity, and the small gap between the sealing slide block 3 and the guide slide plate 20 of the bracket 2 can generate large resistance to air and achieve simple sealing of the gas at normal pressure;

[0093] When the isolation door body 1 is completely closed, the sealing band 9 is in contact with the sealing frame 6, and the sealing band 9 is pressed on the frame channel of the sealing frame 6 due to the closing force generated by the driving device 7;

[0094] When the door is closed, the isolation door body 1 is sealed with the surrounding wall plate 8; the isolation door body 1 has a soft compression material in the middle, which can be tightly sealed when the door is closed; the gap between the sealing sliding block 3 and the sub-isolation door 11 is sealed; through the above measures, the rapid temperature changing room is isolated, and the rapid temperature rising and falling operation can be performed alone to process and observe the experimental model.

[0095] After the experiment is completed, the reverse steps are performed, and the driving device 7 drives the sub-isolation door 11 to open to both sides.

[0096] (2) Experimental model with supporting rods

[0097] ① The driving device 7 drives the isolation door body 1 to open, and the experimental model is loaded into the rapid temperature changing room;

[0098] ② The driving device 7 drives the isolation door body 1 to close, and the isolation door body 1 moves linearly along the sliding rail and the hanging member 41 of the lower rail assembly 5. When the isolation door body 1 is closed to a certain extent, the sealing sliding block 3 will be in contact with the model supporting rod. At this time, the isolation door body 1 continues to close, the sealing sliding block 3 is naturally pushed to both sides by the supporting rod, until the model supporting rod is completely sealed and attached to the low-temperature resistant soft material of the supporting rod hole 10 of the isolation door body 1, and the isolation door body 1 stops moving.

[0099] The rest is the same as the above-mentioned operation without supporting rods.

[0100] It should be understood that during the use of the isolation door of the present application, the surrounding use environment should be kept dry to avoid freezing in low temperature, which causes the sealing sliding block 3 to be frozen and difficult to slide down.
