Description

Technical Field

[0001] This utility model belongs to the technical field of environmental test chambers, and in particular relates to a multi-channel independent control environmental test chamber. Background Technology

[0002] An environmental test chamber is a closed device that uses mechanical control technology to simulate specific environmental conditions (such as temperature, humidity, air pressure, light, salt spray, etc.) to test the performance, reliability and durability of products under different extreme conditions.

[0003] There are many types of environmental test chambers on the market. For example, a climate environmental test chamber with the publication number CN221907153U is disclosed on the Chinese Patent Network. This type of environmental test chamber can be used for product testing, but it has some defects and shortcomings that need to be improved: (1) Due to structural design, most of the existing environmental test chambers have a single chamber, which means that the product can only be tested under one environmental condition each time. When the test environment needs to be changed, the environmental parameters of the relevant equipment (such as temperature, humidity, light, etc.) often need to be reset, which not only reduces the overall working principle, but also wastes resources; (2) Some existing environmental test chambers lack effective protective measures. When subjected to external impacts such as collisions, the surface of the test chamber is prone to bending and deformation, which affects its normal operation; (3) In order to facilitate transportation, some existing environmental test chambers usually install rollers at the bottom. However, the rollers are often fixed at the bottom of the test chamber and are difficult to disassemble, which makes it inconvenient to repair and replace the rollers when they fail. Therefore, in view of the above problems, the multi-channel independent control environmental test chamber provided by this utility model is of great significance. Utility Model Content

[0004] This invention provides a multi-channel independently controlled environmental test chamber. Multiple test chambers and test compartments divide the interior of the chamber into several independent test areas. Each area can be configured with different environmental conditions by adjusting the equipment parameters. This allows for simultaneous testing of the product under test under various environmental conditions through multi-channel independent control, eliminating the need for frequent resetting of equipment parameters. This significantly improves overall work efficiency, saves resources, and avoids waste. A protective frame prevents bending and deformation of the chamber surface from impacts, ensuring proper operation. A movable component allows for easy movement of the chamber using rollers. If the rollers malfunction, the entire movable component can be removed from the bottom of the protective frame by unscrewing the nuts for inspection and replacement. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a multi-channel independent control environmental test chamber, including a chamber body, a door installed on the front side of the chamber body, and several threaded cylinders fixedly connected to the bottom of the chamber body. Each threaded cylinder has a pad installed at its bottom. Several partitions are fixedly connected to the inner wall of the chamber body, and the partitions divide the interior of the chamber body into several test chambers. Each test chamber is rectangular, and a test compartment is placed in each test chamber. Protective frames are fixedly connected to the two outer walls of the chamber body. Several positioning cylinders are fixedly connected to the top of the protective frames, and a moving component is provided at the bottom of the protective frames.

[0007] The movable component includes a mounting base, an electric telescopic rod is mounted on the bottom of the mounting base, a lifting plate is fixedly connected to the bottom end of the output shaft of the electric telescopic rod, and a number of rollers are mounted on the bottom of the lifting plate.

[0008] Furthermore, each of the test chambers has a heat insulation pad on its outer wall surface. The heat insulation pad is rectangular, and its length and width are equal to the length and width of the test chamber, respectively.

[0009] Furthermore, a number of sealing blocks are fixedly connected to the inner side of the box door. The number of sealing blocks is the same as that of the test chamber, and the center of each sealing block corresponds one-to-one with the center of each test chamber. The sealing block is rectangular, and a sealing ring is provided on its side wall surface. The sealing ring is rectangular, and its outer length and width are equal to the length and width of the test chamber, respectively.

[0010] Furthermore, the protective frame is C-shaped, and several reinforcing ribs are fixedly connected between its inner wall and the outer wall of the box. The reinforcing ribs are X-shaped and are distributed linearly at equal intervals along the height direction of the protective frame.

[0011] Furthermore, a top cover is installed on the top of the box body. The top end face of the top cover is inverted V-shaped, and several positioning rods are fixedly connected to its bottom. The number of positioning rods is the same as that of the positioning cylinders, and their diameters correspond to the inner diameters of the positioning cylinders. The center of each positioning rod corresponds one-to-one with the center of each positioning cylinder.

[0012] Furthermore, a screw is fixedly connected to the top of the foot, the diameter of the screw is equal to the inner diameter of the threaded cylinder, and its body is provided with an external thread that mates with the threaded cylinder. A layer of anti-slip pad is provided on the bottom surface of the foot, and the surface of the anti-slip pad is provided with herringbone anti-slip texture.

[0013] Furthermore, the bottom of the protective frame is fixedly connected with several studs, and the studs are threaded with nuts that cooperate with them. The mounting base is provided with several mounting holes, the number of which is the same as the number of studs, and the diameter of the holes corresponds to the diameter of the studs. The center of each mounting hole corresponds one-to-one with the center of each stud.

[0014] The present invention has the following advantages over the prior art:

[0015] (1) When using the multi-channel independent control environmental test chamber of this utility model, the interior of the environmental test chamber can be divided into multiple independent test areas through multiple test chambers and test compartments. Each area can form different environmental conditions by adjusting the parameters of the equipment. Thus, the product under test can be tested under multiple environmental conditions at the same time through multi-channel independent control, without having to frequently reset the environmental parameters of the relevant equipment. This not only greatly improves the overall work efficiency, but also effectively saves resources and avoids waste.

[0016] (2) When using the multi-channel independent control environmental test chamber of this utility model, the protective frame can play a protective role to prevent the surface of the chamber from bending and deforming when the sides of the chamber are impacted by external forces such as collisions, which would affect the normal operation of the environmental test chamber.

[0017] (3) When using the multi-channel independent control environmental test chamber of this utility model, the position of the environmental test chamber can be easily moved by the rolling action between the rollers and the ground through the moving component, so as to complete the transportation work. When the rollers fail, the entire moving component can be removed from the bottom of the protective frame by unscrewing the nut, so as to repair and replace the rollers.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figure 1-6As shown, this utility model discloses a multi-channel independently controlled environmental test chamber, comprising a chamber body 1, a door 2 installed on the front side of the chamber body 1, and several threaded cylinders 3 fixedly connected to the bottom of the chamber body 1. Each threaded cylinder 3 has a foot 4 installed at its bottom. Several partitions 5 are fixedly connected to the inner wall of the chamber body 1, dividing the interior of the chamber body 1 into several test chambers 6. Each test chamber 6 is rectangular, and each test chamber 6 contains a test compartment 7. Each test compartment 7 can be equipped with devices for adjusting environmental conditions (such as refrigeration equipment, heating equipment, etc., not shown in the figure). Through the multiple test chambers 6 and test compartments 7, the interior of the environmental test chamber can be divided into multiple independent test areas. Each area can be shaped by adjusting the parameters of the equipment. Different environmental conditions (such as temperature, humidity, light, etc.) can be set, so that the product under test can be tested under multiple environmental conditions simultaneously through multi-channel independent control, without the need to frequently reset the environmental parameters of related equipment. This not only greatly improves the overall work efficiency, but also effectively saves resources and avoids waste. Protective frames 8 are fixedly connected to the outer walls on both sides of the chamber 1. When the sides of the chamber 1 are impacted by external forces such as collisions, they will first come into contact with the protective frames 8. At this time, the protective frames 8 can play a protective role to prevent the surface of the chamber 1 from bending and deforming, which would affect the normal operation of the environmental test chamber. Several positioning cylinders 9 are fixedly connected to the top of the protective frame 8, and a moving component is set at the bottom of the protective frame 8.

[0031] The moving assembly includes a mounting base 10, with an electric telescopic rod 11 mounted on the bottom of the mounting base 10. A lifting plate 12 is fixedly connected to the bottom end of the output shaft of the electric telescopic rod 11. Several rollers 13 are mounted on the bottom of the lifting plate 12. By driving the electric telescopic rod 11, the lifting plate 12 and the rollers 13 can be moved downward together. When the rollers 13 contact the ground, the position of the environmental test chamber can be easily moved by the rolling action between the rollers 13 and the ground to complete the handling work.

[0032] Each test chamber 7 has a heat insulation pad 14 on its outer wall surface. The heat insulation pad 14 is rectangular, and its length and width are equal to the length and width of the test chamber 6, respectively. The heat insulation pad 14 has a strong heat insulation effect and can be wrapped around each test chamber 7 to prevent the heat in each test chamber 7 from being transferred to the adjacent test chamber 6 and test chamber 7 through the partition 5 and affecting the ambient temperature of other test areas.

[0033] The inner side of the chamber door 2 is fixedly connected with several sealing blocks 15. The number of sealing blocks 15 is the same as that of the test chambers 6, and the center of each sealing block 15 corresponds one-to-one with the center of each test chamber 6. The sealing block 15 is rectangular, and its side wall surface is provided with a sealing ring 16. The sealing ring 16 is rectangular, and its outer length and width are equal to the length and width of the test chamber 6, respectively. The sealing ring 16 can be made of elastic materials such as rubber and is fixed by means of glue. When the chamber door 2 is closed, each sealing block 15 can extend into the corresponding test chamber 6. At this time, the sealing ring 16 can fit against the inner wall of each test chamber 6 to fill the gap between each sealing block 15 and the test chamber 6, thereby effectively improving the sealing performance of the chamber door 2 and preventing cold air and moisture in the outside air from entering the test chamber 6 through the gap and affecting the test environment in each test chamber 7.

[0034] The protective frame 8 is C-shaped, and its inner wall is fixedly connected to the outer wall of the box 1 with several reinforcing ribs 17. The reinforcing ribs 17 are X-shaped and are distributed linearly at equal intervals along the height direction of the protective frame 8. The protective frame 8 can be reinforced by multiple reinforcing ribs 17 to improve the structural strength and deformation resistance of the protective frame 8, thereby effectively extending the service life of the protective frame 8.

[0035] The top of the box 1 is equipped with a top cover 18. The top end face of the top cover 18 is inverted V-shaped, and several positioning rods 19 are fixedly connected to its bottom. The number of positioning rods 19 is the same as that of the positioning cylinders 9, and their diameters correspond to the inner diameters of the positioning cylinders 9. The center of each positioning rod 19 corresponds one-to-one with the center of each positioning cylinder 9. Each positioning rod 19 can be aligned and inserted into the corresponding positioning cylinder 9. Through the cooperation between the positioning rods 19 and the positioning cylinders 9, the top cover 18 can be fixedly installed on the top of the box 1. The top cover 18 can play a role in dust and water protection to prevent the top of the box 1 from getting dusty and wet. At the same time, the top cover 18 can also protect the top of the box 1 to prevent heavy objects from falling onto the top of the box 1 and causing damage to the box 1.

[0036] The top of the foot 4 is fixedly connected to a screw 20, the diameter of which corresponds to the inner diameter of the threaded cylinder 3. The screw 20 has an external thread that mates with the threaded cylinder 3. The bottom surface of the foot 4 is provided with an anti-slip pad 21, which has a herringbone anti-slip texture. The anti-slip pad 21 can be made of elastic materials such as rubber and is fixed by means of glue. The screw 20 can be threaded into the threaded cylinder 3 so that the foot 4 can be fixedly installed at the bottom of each threaded cylinder 3 through the threaded engagement. The foot 4 can support the chamber 1 so that it can be lifted off the ground. The anti-slip texture on the surface of the anti-slip pad 21 can increase the friction between the foot 4 and the ground to play an anti-slip role, thereby effectively preventing the environmental test chamber from slipping and shifting. When the anti-slip pad 21 wears out due to prolonged contact with the ground, the foot 4 can be removed from the corresponding threaded cylinder 3 by unscrewing the screw 20 so that the anti-slip pad 21 can be replaced.

[0037] The bottom of the protective frame 8 is fixedly connected with several studs 22. The studs 22 are threaded with nuts 23 that mate with them. The mounting base 10 has several mounting holes 24. The number of mounting holes 24 is the same as that of the studs 22. The diameter of the holes corresponds to the diameter of the studs 22. The center of each mounting hole 24 corresponds to the center of each stud 22. Each stud 22 can be aligned and passed through the corresponding mounting hole 24. At this time, the nuts 23 are threaded onto each stud 22 and tightened. The mounting base 10, together with the entire moving assembly, is fixedly installed at the bottom of the protective frame 8 through the mutual cooperation between the studs 22, mounting holes 24, and nuts 23. When the roller 13 malfunctions, the entire moving assembly can be removed from the bottom of the protective frame 8 by unscrewing the nuts 23 for inspection and replacement of the roller 13.

[0038] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0039] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0040] The working principle of this utility model is as follows:

[0041] In use, this invention divides the interior of the chamber 1 into several test chambers 6 using multiple partitions 5. Each test chamber 6 contains a test compartment 7, and each test compartment 7 can be equipped with devices for adjusting environmental conditions (such as refrigeration or heating equipment, not shown in the figure). The multiple test chambers 6 and test compartments 7 divide the interior of the environmental test chamber into multiple independent test areas. Each area can be configured with different environmental conditions (such as temperature, humidity, and light intensity) by adjusting the parameters of the equipment. This allows for simultaneous testing of the product under test under various environmental conditions through multi-channel independent control, eliminating the need for frequent resetting of the environmental parameters of the relevant equipment. This significantly improves overall work efficiency, effectively saves resources, and avoids waste. Protective frames 8 are fixedly connected to both outer walls of the chamber 1. When the sides of the chamber 1 are impacted by external forces such as collisions, they will first come into contact with the protective frames 8. At this time, the protective frames 8 can play a protective role to prevent the surface of the chamber 1 from bending and deforming, which would affect the normal operation of the environmental test chamber. When the environmental test chamber needs to be moved, the electric telescopic rod 11 can be driven to move the lifting plate 12 and the rollers 13 downward together until the rollers 13 contact the ground. At this time, the position of the environmental test chamber can be easily moved by the rolling action between the rollers 13 and the ground to complete the moving work. When the rollers 13 malfunction, the entire moving assembly can be removed from the bottom of the protective frame 8 by unscrewing the nut 23 to repair and replace the rollers 13.
