Description

Technical Field

[0001] This utility model relates to the technical field of constant temperature and humidity chambers, and in particular to a sealing structure for a constant temperature and humidity control chamber. Background Technology

[0002] A constant temperature and humidity control chamber is a device that can precisely regulate and maintain a stable temperature and humidity inside the chamber. The sealing structure is a key part of the constant temperature and humidity control chamber that prevents the exchange of air, water vapor and heat between the inside and outside of the chamber in order to maintain a stable temperature and humidity environment inside the chamber.

[0003] The sealing structure of existing constant temperature and humidity control boxes generally suffers from a short sealing lifespan during long-term use. In traditional structures, the sealing strips mostly rely on a single compression method to achieve a seal. When the temperature difference between the inside and outside of the box causes thermal expansion and contraction of components, frequent opening and closing of the door causes mechanical wear, and the sealing strips lose elasticity due to aging, there is a lack of an effective pressure compensation mechanism.

[0004] The connection structure of external components such as humidifiers often adopts bolt fixing or simple snap-fit ​​design. During disassembly and assembly, the seals are easily subjected to excessive compression and friction, which accelerates the wear of the seals and further shortens the service life of the overall sealing structure. This makes it difficult to meet the long-term stable sealing requirements. Therefore, a sealing structure for a constant temperature and humidity control box is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a sealing structure for a constant temperature and humidity control box, aiming to improve the problem that in the prior art, some constant temperature and humidity control box seals are prone to excessive compression and friction during disassembly and assembly, which accelerates the wear of the seals and further shortens the service life of the overall sealing structure.

The opposite sides of the multiple extrusion plates are in contact with the adjacent sides of the multiple sealing strips.

[0012] As a further description of the above technical solution:

[0013] The compensation component includes multiple connecting plates, with the outer sides of the multiple connecting plates fixedly connected to the interior of the intelligent temperature and humidity chamber.

The pressing rod is slidably connected to the exterior of the fixed slotted column. A sealing ring b is fitted on the bottom of the outer side of the connecting pipe, and the bottom of the sealing ring b is fixedly connected to the top of the exterior of the intelligent temperature and humidity chamber.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1, Figure 2 This utility model provides an embodiment of a constant temperature and humidity control box sealing structure, including an intelligent temperature and humidity box 1. A horizontal support plate 2 is fixedly connected to the right side of the intelligent temperature and humidity box 1. A drive assembly is fixedly connected to the top of the horizontal support plate 2, which supports the drive assembly. A slotted turntable 5 is fixedly connected to the left side of the drive assembly. The slotted turntable 5 has multiple grooves 6 inside, and each groove 6 has a slidably connected compression assembly. Multiple sealing strips 8 are placed inside the intelligent temperature and humidity box 1. The drive assembly can adjust the rotation state of the slotted turntable 5 to control the degree of compression of the sealing strips 8 by the compression assembly. A compensation assembly is fixedly connected to the right side of the intelligent temperature and humidity box 1. A vertical support plate 11 is fixedly connected to the inside of the intelligent temperature and humidity box 1. A sealing plate 23 is fixedly connected to the right side of the vertical support plate 11, which supports the sealing plate 23. The drive assembly includes a motor 3, the bottom of which is fixedly connected to the top of the horizontal support plate 2. The drive end of motor 3 is fixedly connected to a rotating shaft a4. The left side of rotating shaft a4 is fixedly connected to the right side of slotted turntable 5. The extrusion assembly includes multiple sliding columns 24. The groove 6 provides a track for the sliding columns 24, restricting the movement direction of the sliding columns 24, so that the sliding columns 24 can slide with the rotation of slotted turntable 5. The external parts of multiple sliding columns 24 are slidably connected to the inside of multiple grooves 6. Extrusion plates 7 are rotatably connected to the external parts of multiple sliding columns 24. Under the drive of the sliding columns 24, the extrusion plates 7 directly contact the sealing strip 8 and exert an extrusion effect on it, causing the sealing strip 8 to deform, filling the sealing gap, and enhancing the sealing effect. The far side of multiple extrusion plates 7 is in contact with the near side of multiple sealing strips 8. The compensation assembly includes multiple connecting plates 9. The far side of the external parts of multiple connecting plates 9 is fixedly connected to the inside of intelligent temperature and humidity chamber 1. Springs 10 are fixedly connected to the right side of multiple connecting plates 9. The right side of multiple springs 10 is in contact with the left side of sealing plate 23.

[0033] Reference Figure 1 , Figure 3 , Figure 4A connecting pipe 14 is fixedly connected to the top of the intelligent temperature and humidity chamber 1. A locking assembly is fixedly connected to the top of the connecting pipe 14. A humidifier 16 is placed on the top of the connecting pipe 14. The humidifier 16 delivers moisture into the intelligent temperature and humidity chamber 1 through the connecting pipe 14 to regulate the humidity inside the chamber. The connecting pipe 14 connects the intelligent temperature and humidity chamber 1 and the humidifier 16, serving as a channel for the humidifier 16 to deliver moisture into the intelligent temperature and humidity chamber 1. The locking assembly includes a sealing ring a15, the bottom of which is fixedly connected to the top of the connecting pipe 14. A fixed slotted post 18 is fixedly connected to the outside of the connecting pipe 14. The humidifier 16 is internally connected to a rotating shaft b19, and externally fixed to the rotating shaft b19 is an eccentric disk 20. Externally fixed to the eccentric disk 20 is a pressing rod 21. The eccentric disk 20 rotates under the drive of the rotating shaft b19. When it rotates to contact the annular groove 17, it uses its eccentric structure to generate a squeezing force on the humidifier 16, pressing the humidifier 16 tightly onto the connecting pipe 14, thus fixing the two. When it rotates in the opposite direction, it disengages from the annular groove 17, releasing the fixation on the humidifier 16. The humidifier 16 has an annular groove 17 on its outside, and the eccentric disk 20 can contact the inside of the annular groove 17. The pressing rod 21 is slidably connected to the outside of the fixed slotted column 18.

[0034] Reference Figure 1 , Figure 4 A controller 13 is fixedly connected to the front of the intelligent temperature and humidity chamber 1. The controller 13 displays real-time temperature and humidity data, operating status and other information and controls the temperature and humidity inside the device. A viewing window 12 is fixedly connected to the front of the intelligent temperature and humidity chamber 1. The viewing window 12 is made of transparent material, allowing the operator to observe the state of the test sample and the changes in temperature and humidity environment inside the chamber without opening the chamber. A sealing ring b22 is fitted on the bottom of the connecting pipe 14. The bottom of the sealing ring b22 is fixedly connected to the top of the intelligent temperature and humidity chamber 1. The sealing ring b22 fills the gap between the connecting pipe 14 and the top of the intelligent temperature and humidity chamber 1, enhancing the sealing of this part.

[0035] Working principle: Motor 3 drives the slotted turntable 5 to rotate through the rotating shaft a4. The groove 6 of the slotted turntable 5 guides the sliding column 24 to slide, causing the extrusion plate 7 to swing and extrude the sealing strip 8. Under the extrusion action, the sealing strip 8 undergoes elastic deformation, filling the gaps in the intelligent temperature and humidity chamber 1 and blocking the exchange of air and water vapor inside and outside the chamber. At the same time, the spring 10 in the compensation component applies force to the sealing plate 23, making the sealing plate 23 and the sealing strip 8 fit tightly together, further enhancing the sealing effect. The vertical support plate 11 provides stable support for the sealing plate 23.

[0036] The sealing ring a15 is located at the top of the connecting pipe 14. When the humidifier 16 is placed on the connecting pipe 14, the sealing ring a15 first fills the gap. Then, the pressing rod 21 is moved, which drives the eccentric disk 20 to rotate around the rotating shaft b19. The eccentric disk 20 enters the annular groove 17 of the humidifier 16 and generates a squeezing force, pressing the humidifier 16 tightly onto the connecting pipe 14. This causes the sealing ring a15 to deform further, enhancing the sealing performance. The sealing ring b22 at the bottom of the outer side of the connecting pipe 14 fills the gap between the connecting pipe 14 and the top of the intelligent temperature and humidity chamber 1, forming a double seal to prevent leakage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
