Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a high and low temperature test chamber. Background Technology

[0002] High and low temperature test chambers are mainly used to check the performance indicators of various products, materials or other items under high and low temperature changes. For example, the high and low temperature test chamber disclosed in patent number CN202020836604.0. Most high and low temperature test chambers in the prior art adopt outward-opening hinged doors. However, there are some drawbacks to using outward-opening hinged doors: on the one hand, when the hinged door is opened, as the hinged door needs to swing outward, the staff needs to follow and avoid it, which means that the test chamber needs to occupy a large external space during opening. In the laboratory or other limited space, it is easy to interfere with the surrounding equipment; on the other hand, after frequent opening and closing operations, the hinge components are prone to loosening and deformation due to long-term stress, resulting in the door sinking, incomplete closing, etc., which in turn affects the sealing performance of the test chamber.

[0003] Based on this, the applicant is considering designing a space-saving high and low temperature test chamber with a door that is not prone to sinking. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a high and low temperature test chamber that saves space and whose door is not easy to sink.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high and low temperature test chamber includes a test chamber body and a sliding door assembly. The test chamber body has a test chamber opening on the front side. The sliding door assembly includes a door body and a guide fixedly connected to the test chamber body.

[0007] A sealing element is connected to the side of the door facing the experimental chamber opening. The door moves on the guide to either block or open the experimental chamber opening. When the door blocks the experimental chamber opening, the guide guides the door closer to the front of the experimental chamber body so that the sealing element contacts the front of the experimental chamber body. When the door opens the experimental chamber opening, the guide guides the door away from the front of the experimental chamber body, releasing the contact between the sealing element and the front of the experimental chamber body.

[0008] The working principle and advantages of this high and low temperature test chamber are as follows:

[0009] When the experimental chamber needs to be closed, move the door on the guide to block the experimental compartment opening. Simultaneously, the guide guide moves the door closer to the front of the experimental chamber, ensuring the door's seal contacts the front of the chamber. When the experimental chamber needs to be opened, move the door on the guide until it no longer blocks the experimental compartment opening. Simultaneously, the guide guide moves the door away from the front of the chamber, releasing the seal from contact with the front. This solution uses a sliding door assembly to open and close the experimental compartment opening. The outward-opening hinged door effectively reduces the space occupied by the experimental chamber when it is opened, avoids interference with surrounding equipment in space-constrained environments such as laboratories, and improves space utilization efficiency. The guide components of the sliding door assembly support and guide the door body, reducing the sinking phenomenon caused by gravity during frequent opening and closing, and ensuring the sealing and reliability of the experimental chamber. The sealing components connected to the door body make tight contact with the front side of the experimental chamber body when the door body covers the experimental chamber opening, forming a good sealing effect and improving the sealing performance of the experimental chamber body.

[0010] Furthermore, the guide includes a first guide plate and a second guide plate fixedly connected to the front side of the experimental chamber body and spaced apart, the door is installed between the two, and guide grooves are provided on the opposite side of the first guide plate and the second guide plate. Movable wheels that are movably disposed in the guide grooves are installed at the top and bottom of the door.

[0011] Furthermore, the guide groove includes a distance section, a closed section, and a transition section connecting the two; when the movable wheel is located in the distance section, the door is in the open experimental chamber state; when the movable wheel is located in the closed section, the door is in the closed experimental chamber state.

[0012] Furthermore, the sealing element includes a first sealing ring. When the door covers the experimental chamber opening, the first sealing ring abuts against the front side of the experimental chamber body to form an annular closed barrier, and the experimental chamber opening is located within the annular closed barrier.

[0013] Furthermore, a compression structure for compressing the first sealing ring is installed inside the door body.

[0014] Furthermore, the extrusion structure includes an annular moving cavity and an annular extrusion opening within the door body; a magnetic suction ring plate is movably installed within the moving cavity, and an extrusion protrusion ring is provided on the side of the magnetic suction ring plate facing the extrusion opening; the magnetic suction ring plate is magnetically attracted to the side of the moving cavity near the first sealing ring and the side away from the first sealing ring; when the magnetic suction ring plate is magnetically attracted to the side of the moving cavity near the first sealing ring, the extrusion protrusion ring extends out of the extrusion opening to extrude extrusion ring; when the magnetic suction ring plate is magnetically attracted to the side of the moving cavity away from the first sealing ring, the extrusion protrusion ring retracts to release the extrusion ring from the first sealing ring.

[0015] Furthermore, a handle is movably connected to the side of the door away from the experimental chamber opening, and the handle extends into the movable cavity and is fixedly connected to the magnetic suction ring plate.

[0016] Furthermore, a second sealing ring located inside the first sealing ring is fixedly connected to the side of the door facing the experimental chamber opening. When the door blocks the experimental chamber opening, the second sealing ring extends into the experimental chamber opening and its outer wall is press-fitted with the inner wall of the experimental chamber opening.

[0017] Furthermore, the door is provided with a transparent window.

[0018] Furthermore, the guide is provided with an extension extending to the front side of the experimental chamber body, so that the door can move to the front side of the experimental chamber body. Attached Figure Description

[0036] Refer to together Figures 1 to 10This embodiment provides a high and low temperature test chamber, which includes a test chamber body 100 and a sliding door assembly 200. The test chamber body 100 has a test chamber opening 110 on the front side. The sliding door assembly 200 includes a door body 220 and a guide member 210 fixedly connected to the test chamber body 100.

[0037] A sealing element is connected to the side of the door 220 facing the experimental chamber opening 110. The door 220 moves on the guide 210 to block or open the experimental chamber opening 110. When the door 220 blocks the experimental chamber opening 110, the guide 210 guides the door 220 closer to the front of the experimental chamber body 100 so that the sealing element abuts against the front of the experimental chamber body 100. When the door 220 opens the experimental chamber opening 110, the guide 210 guides the door 220 away from the front of the experimental chamber body 100, releasing the seal from abutting against the front of the experimental chamber.

[0038] In this implementation, when the experimental chamber body 100 needs to be closed, the door 220 on the guide 210 is moved so that the door 220 blocks the experimental compartment opening 110 on the experimental chamber body 100. Simultaneously, the guide 210 guides the door 220 closer to the front of the experimental chamber body 100, so that the seal on the door 220 contacts the front of the experimental chamber body 100. When the experimental chamber body 100 needs to be opened, the door 220 on the guide is moved so that it no longer blocks the experimental compartment opening 110 on the experimental chamber body 100. Simultaneously, the guide 210 guides the door 220 away from the front of the experimental chamber body 100, releasing the seal from contact with the front of the experimental chamber. This solution uses the sliding door assembly 200 to... The experimental chamber opening 110 of the experimental chamber body 100 opens and closes, which, compared to an outward-opening hinged door, effectively reduces the space occupied by the experimental chamber when it is opened, avoids interference with surrounding equipment in space-constrained environments such as laboratories, and improves space utilization efficiency. The guide component 210 of the sliding door assembly 200 supports and guides the door body 220, reducing the sinking phenomenon of the door body 220 due to gravity during frequent opening and closing, ensuring the sealing and reliability of the experimental chamber. The sealing component connected to the door body 220 makes tight contact with the front side of the experimental chamber body 100 when the door body 220 covers the experimental chamber opening 110, forming a good sealing effect and improving the sealing performance of the experimental chamber body 100.

[0039] Preferably, such as Figures 1 to 6As shown, the guide component 210 includes a first guide plate 211 and a second guide plate 212 fixedly connected to the front side of the experimental chamber body 100 and spaced apart. The door body 220 is installed between the two. Guide grooves 213 are provided on the opposite sides of the first guide plate 211 and the second guide plate 212. Movable wheels 221 are installed at the top and bottom of the door body 220 and are movably disposed in the guide grooves 213. The first guide plate 211 and the second guide plate 212 form a stable track, and the movable wheels 221 move in the guide grooves 213, which can guide the door body. The top and bottom of the door 220 are supported to ensure the stability of the door 220 when it moves horizontally, and the sealing element tightly abuts against the front side of the test chamber body 100. Specifically, at least two movable wheels 221 are connected to the top and bottom of the door 220 respectively. The movable wheels 221 are detachably connected to the door 220. When the movable wheels 221 on the door 220 are removed, the door 220 can be easily removed from between the first guide plate 211 and the second guide plate 212 for easy maintenance and replacement. More specifically, the movable wheels 221 can directly adopt the universal wheels in the prior art.

[0040] Preferably, such as Figures 1 to 6 As shown, the guide groove 213 includes a distance section 2131, a closed section 2133, and a transition section 2132 connecting the two. When the movable wheel 221 is located in the distance section 2131, the door 220 is in the open state of the experimental chamber opening 110; when the movable wheel 221 is located in the closed section 2133, the door 220 is in the closed state of the experimental chamber opening 110. The segmented design of the guide groove 213 allows the door 220 to move between the distance section 2131 and the closed section 2133, thereby opening or closing the experimental chamber opening 110. When the movable wheel 221 moves into the closed section 2133, the door 220 moves closer to the experimental chamber body 100, so that the sealing element is in close contact with the front side of the experimental chamber body 100, ensuring sealing. When the door 220 moves to the distance section 2131, it moves away from the experimental chamber body 100, releasing the seal and facilitating the movement of the door 220. The transition section 2132 ensures that the door 220 has sufficient buffer space during opening and closing, allowing the movable wheel 221 to smoothly slide from the distance section 2131 into the closed section 2133, or from the closed section 2133 to the distance section 2131. The operator only needs to push the door 220 to open or close it by moving the movable wheel 221 in the guide groove 213. No additional auxiliary tools are required, making the operation simple and improving work efficiency. The design of the transition section 2132 makes the door 220 more stable during opening and closing, reducing shaking or jamming.

[0041] Preferably, such as Figures 6 to 8As shown, the sealing element includes a first sealing ring 230. When the door 220 blocks the experimental chamber opening 110, the first sealing ring 230 abuts against the front side of the experimental chamber body 100, forming an annular closed barrier, and the experimental chamber opening 110 is located within the annular closed barrier. When the first sealing ring 230 abuts tightly against the front side of the experimental chamber body 100, the annular closed barrier formed and the experimental chamber opening 110 is completely surrounded within the annular closed barrier can effectively prevent air exchange between the inside and outside of the experimental chamber body 100, thereby maintaining the temperature stability inside the experimental chamber, preventing temperature leakage, maintaining a stable experimental environment, reducing energy consumption, and lowering operating costs.

[0042] Preferably, a compression structure is installed inside the door 220 to compress the first sealing ring 230; when the door 220 blocks the experimental chamber opening 110, the compression structure applies additional pressure to the first sealing ring 230, which allows the first sealing ring 230 to fit more tightly against the front side of the experimental chamber body 100, enhancing the sealing effect; the compression of the compression structure can compensate for the wear of the sealing ring caused by long-term use, ensuring the durability of the sealing performance.

[0043] Preferably, such as Figures 7 to 9 As shown, the extrusion structure includes an annular moving cavity 260 and an annular extrusion opening 262 within the door body 220. A magnetic suction ring plate 252 is movably installed within the moving cavity 260. A compression protrusion ring 251 protrudes from the side of the magnetic suction ring plate 252 facing the extrusion opening 262. The magnetic suction ring plate 252 magnetically attracts the side of the moving cavity 260 near the first sealing ring 230 and the side away from the first sealing ring 230. When the magnetic suction ring plate 252 magnetically attracts the side of the moving cavity 260 near the first sealing ring 230, the compression protrusion ring 251 extends out of the extrusion opening 262 to compress the first sealing ring 230. When the magnetic suction ring plate 252 magnetically attracts the side of the moving cavity 260 away from the first sealing ring 230, the compression protrusion ring 251 retracts to release the compression of the first sealing ring 230. 52 can switch positions within the moving cavity 260. When the magnetic ring plate 252 is attracted to the side near the first sealing ring 230, the extrusion protrusion 251 extends from the extrusion port 262 and applies uniform extrusion to the first sealing ring 230, thereby enhancing the tightness of the seal ring in contact with the front of the experimental chamber body 100, effectively preventing internal gas leakage and ensuring the temperature stability of the experimental environment. When the magnetic ring plate 252 is attracted to the side away from the first sealing ring 230, the extrusion protrusion 251 retracts into the moving cavity 260, releasing the extrusion on the sealing ring and facilitating the opening of the door 220. Specifically, magnetic blocks 261 that are magnetically connected to the magnetic ring plate 252 are embedded on both the side of the moving cavity 260 near the first sealing ring 230 and the side away from the first sealing ring 230.

[0044] Preferably, such as Figures 2 to 9As shown, a handle 270 is movably connected to the side of the door 220 away from the experimental chamber opening 110. The handle 270 extends into the movable cavity 260 and is fixedly connected to the magnetic ring plate 252. The handle 270 and the magnetic ring plate 252 are fixedly connected. By pushing or pulling the handle 270, the magnetic ring plate 252 moves within the movable cavity 260. When sealing is required, pushing the handle 270 causes the magnetic ring plate 252 to approach the first sealing ring 230, and the compression protrusion 251 extends out of the compression port 262 to compress the sealing ring. When it is necessary to open the door 220 or replace... When sealing the ring, pull the handle 270 to move the magnetic ring plate 252 away from the first sealing ring 230, and squeeze the protruding ring 251 to retract, releasing the compression on the sealing ring; the handle 270 is located on the side of the door 220 away from the experimental chamber opening 110, which is reasonable and ergonomic, and the operator can operate it intuitively; specifically, it includes two U-shaped handles 270, which are fixedly connected by a horizontal bar 271. The operator can control the movement of the door 220 and the magnetic ring plate 252 by operating the two handles 270 or the horizontal bar.

[0045] Preferably, such as Figures 6 to 8 As shown, a second sealing ring 240 located inside the first sealing ring 230 is fixedly connected to the side of the door 220 facing the experimental chamber opening 110. When the door 220 blocks the experimental chamber opening 110, the second sealing ring 240 extends into the experimental chamber opening 110 and its outer wall is press-fitted with the inner wall of the experimental chamber opening 110. The press-fit between the second sealing ring 240 and the experimental chamber opening 110 generates pressure through elastic deformation, which further enhances the sealing effect and prevents internal gas leakage. The opening and closing actions of the second sealing ring 240 and the door 220 are synchronized. Specifically, the first sealing ring 230 and the second sealing ring 240 are made of flexible materials that are resistant to high and low temperatures in the prior art.

[0046] Preferably, such as Figure 5 and Figure 6 As shown, a transparent window 222 is provided on the door 220; the transparent window 222 facilitates observation of the situation inside the experimental chamber.

[0047] Preferably, such as Figures 1 to 6As shown, the guide member 210 is provided with an extension extending to the front side of the experimental chamber body 100, so that the door 220 can move to the front side of the experimental chamber body 100. In the prior art, some experimental chambers have an experimental compartment opening 110 with a front width that is insufficient for the door 220 to move to fully open the experimental compartment opening 110. The extension of the guide member 210 provides additional moving space for the door 220, ensuring that the door 220 can fully open the experimental compartment opening 110. Moreover, when the door 220 moves to the front side of the experimental chamber body 100, it can expose the side of the door 220 facing the experimental chamber body 100, which is convenient for maintenance, cleaning and replacement of the door 220. The extension of the guide member 210 includes a first guide plate 211 and a second guide plate 212 extending out of the front end of the experimental chamber body 100.

[0048] Specifically, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 10 As shown, the sliding door assembly 200 also includes a triangular reinforcing frame 300 connecting the guide member 210 and the experimental chamber body 100; the triangular reinforcing frame 300 includes two triangular frames 310, which are fixedly connected by three connecting posts 320. The two adjacent sides of one triangular frame 310 are fixedly connected to the side wall of the experimental chamber body 100 and the first guide plate 211, respectively, and the two adjacent sides of the other triangular frame 310 are fixedly connected to the side wall of the experimental chamber body 100 and the second guide plate 212, respectively; the triangular reinforcing frame 300 can improve the connection strength between the guide member 210 and the experimental chamber body 100.

[0049] Specifically, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 as well as Figure 8 As shown, the first sealing ring 230 has an annular groove 231 on the side facing the experimental chamber body 100. A protruding ring 120 corresponding to the annular groove 231 is fixedly connected to the front side of the experimental chamber body 100. When the door 220 blocks the experimental chamber opening 110, the protruding ring 120 is embedded in the annular groove 231 of the first sealing ring 230, further enhancing the sealing effect. More specifically, the protruding ring 120 and the above-mentioned extrusion protrusion 251 can be magnetically connected to improve the extrusion effect.

[0050] Specifically, such as Figure 1 and Figure 2As shown, a baffle 130 is also fixedly connected to the front side of the experimental chamber body 100. When the door 220 blocks the experimental chamber opening 110, the side wall of the door 220 abuts against the baffle 130. The baffle 130 can restrict the door 220 and prevent the door 220 from moving excessively. More specifically, the side wall of the door 220 and the baffle 130 can be magnetically connected so that the door 220 can more stably maintain the state of blocking the experimental chamber opening 110.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
