Description

Technical Field

[0001] This utility model relates to the field of constant temperature and humidity testing, and more particularly to an openable constant temperature and humidity test chamber. Background Technology

[0002] According to customer feedback, some test samples are large in size. During testing, it is necessary to remove the top cover of the test chamber, use hoisting equipment to lift the product into the test chamber, and then reinstall the top cover on the top of the test chamber.

[0003] Although traditional test chambers can disassemble large test samples, the original design of the test chamber did not take into account testing large samples in this way. Therefore, with frequent disassembly, the sealing performance between the top cover and the chamber body drops sharply. In order to avoid abnormal temperature in the test environment, the frequency of maintenance can be increased to alleviate the occurrence of the above problems. However, the result is that labor costs and maintenance costs will increase significantly. In particular, the additional disassembly and assembly process for testing large products leads to low overall testing efficiency. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an openable constant temperature and humidity test chamber, aiming to solve the issues of low testing efficiency and decreased sealing performance of the test chamber when handling large test samples.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an openable constant temperature and humidity test chamber, comprising a test tank, wherein a blower for stirring the internal airflow is provided in the test tank, characterized in that the interior of the test tank is composed of a fixed box and a movable box spliced ​​together, wherein the movable box integrates a platform extending outward from the main body, and the two sides of the platform are inclined surfaces adapted to the bottom surface of the movable box, the movable box moves along the horizontal direction onto the inclined surface, and the interior of the test tank is formed after the two are tightly fitted together.

[0006] The beneficial effects of this utility model are:

[0007] This utility model provides a design scheme specifically for large test samples. The scheme designs the test tank as a detachable structure, which can be separated from the fixed box by a movable box, resulting in an exposed platform. At this point, the large test sample can be directly hoisted or placed on the platform by other transportation mechanisms, and then the movable box is pushed to join the fixed box to seal the large test sample. In the whole process, there is no need to perform actions such as disassembling the top cover, thus eliminating the step of disassembling the top cover, significantly improving efficiency, saving a lot of labor, and significantly optimizing maintenance costs.

[0008] It also includes a guide rail, pulleys, and a drive mechanism. The guide rail is set outside the test chamber, the pulley is set on the moving box and slidably connected to the guide rail, and the drive mechanism is set on the side of the test chamber. The movable end of the drive mechanism is connected to the moving box and drives the moving box to move linearly back and forth. With the above scheme, the guide rail and pulley guidance method has the characteristics of structural stability, and the rolling method reduces the pushing resistance.

[0009] The aforementioned drive mechanism includes a reducer and a rack. One end of the rack is fixed to the movable box, and the reducer is located outside the fixed box. The output gear of the reducer meshes with the other end of the rack. By adopting the above solution, in addition to providing precise speed regulation, it can also provide greater output torque.

[0010] Considering the splicing and assembly between the fixed box and the mobile box, a sealing strip is provided on the side of the platform and the fixed box facing the mobile box. The sealing strip is compressed by the mobile box to isolate the air exchange between the inside of the test tank and the outside.

[0011] The fixed box and the mobile box need to be locked together. In order to improve the success rate of this locking and the retention of the lock, a locking device with a linkage mechanism is adopted. The locking device includes a locking part and a lock head. The linkage mechanism is the transmission part in the locking part. The locking part in the locking part has a rotational action for locking on the test slot under the guidance of the linkage mechanism, so that the locking part is mounted on the back of the lock head and in close contact with the lock head in the locked state.

[0012] The aforementioned linkage mechanism includes a positioning pair and a rotating pair. The positioning pair is connected to the first end of the locking member and forms the rotation axis of the locking member. The rotating pair includes a driving pair and a driven pair. The central rotation axis of the driving pair is connected to the positioning pair. The eccentric shaft end of the driving pair is coaxially connected to one end of the driven pair. The other end of the driven pair is rotatably connected to the locking member. When the driving pair rotates, it guides the driven pair to raise or lower the locking member. When raised, the constraint on the driven pair causes the locking member to ultimately lock the locking head.

[0013] The linkage mechanism is designed based on the cylinder seat, the cylinder, and the lock head whose assembly position remains unchanged. The cylinder is located below the cylinder seat, and the driving pair is V-shaped. In this specific implementation, there are two eccentric shafts, one of which is connected to the piston rod of the cylinder. The positioning pair is directly fixed to the cylinder seat. In this specific implementation, the lock head is located above the cylinder seat. In this way, the locking component can rotate and abut against the lock head to complete the locking.

[0014] A preferred design is that the lock head is a roller mounted on one end of the lever, which is horizontal. When locked, the locking element is in close contact with the roller, and the rolling friction reduces wear on the locking element.

[0015] The locking part is located on the side of the fixed box, and the lock head is located on the side of the movable box. Attached Figure Description

[0024] like Figure 1-8 As shown, an openable constant temperature and humidity test chamber includes a test tank, and a blower 1a for stirring the internal airflow is provided in the test tank. The test tank is characterized in that the interior of the test tank is formed by splicing a fixed box 100 and a movable box 101. The movable box 101 integrates a platform 101a extending outward from the main body. The two sides of the platform 101a are inclined surfaces 101b adapted to the bottom surface of the movable box 101. The movable box 101 moves along the horizontal direction onto the inclined surfaces 101b, and the two are tightly fitted together to form the interior of the test tank.

[0025] The beneficial effects of this utility model are:

[0026] This utility model provides a design scheme specifically for large test samples 4. The scheme designs the test tank as a detachable structure, which can be separated from the fixed box 100 by the movable box 101, resulting in the exposed platform 101a. At this time, the large test sample 4 can be directly hoisted or placed on the platform 101a by other transportation mechanisms, and then the movable box 101 is pushed to join with the fixed box 100 to seal the large test sample 4. In the whole process, there is no need to perform actions such as disassembling the top cover, thus eliminating the step of disassembling the top cover, significantly improving efficiency, saving a lot of labor, and significantly optimizing maintenance costs.

[0027] It also includes a guide rail 21, a pulley 22, and a drive mechanism. The guide rail 21 is set outside the test chamber, and the pulley 22 is set on the movable box 101 and slidably connected to the guide rail 21. The drive mechanism is set on the side of the test chamber, and the movable end of the drive mechanism is connected to the movable box 101, driving the movable box 101 to move linearly back and forth. With the above scheme, the guiding method using the guide rail 21 and the pulley 22 has the characteristics of structural stability, and the rolling method reduces the resistance of pushing.

[0028] The aforementioned drive mechanism includes a reducer and a rack 23. One end of the rack 23 is fixed to the movable box 101, and the reducer is located outside the fixed box 100. The output gear of the reducer meshes with the other end of the rack 23. By adopting the above solution, in addition to providing precise speed regulation, it can also provide greater output torque.

[0029] Considering the splicing and assembly between the fixed box 100 and the movable box 101, a sealing strip 101c is provided on the side of the platform 101a and the fixed box 100 facing the movable box 101. The sealing strip 101c is squeezed by the movable box 101 to isolate the air exchange between the inside of the test tank and the outside.

[0030] The fixed box 100 and the movable box 101 need to be locked together. In order to improve the success rate of this locking and maintain a high locking position, a locking device with a linkage mechanism is adopted. The locking device includes a locking part 300 and a locking head 301. The linkage mechanism is the transmission part in the locking part 300. The locking member 300a in the locking part 300 has a rotational action for locking on the test slot under the guidance of the linkage mechanism, so that in the locked state, the locking member 300a is mounted on the back of the locking head 301 and in close contact with the locking head 301.

[0031] The aforementioned linkage mechanism includes a positioning pair 300b-1 and a rotating pair. The positioning pair 300b-1 is connected to the first end of the locking member 300a and forms the rotation axis of the locking member 300a. The rotating pair includes a driving pair 300b-2 and a driven pair 300b-3. The central rotation axis of the driving pair 300b-2 is connected to the positioning pair 300b-1. The eccentric shaft end of the driving pair 300b-2 is coaxially connected to one end of the driven pair 300b-3. The other end of the driven pair 300b-3 is rotatably connected to the locking member 300a. When the driving pair 300b-2 rotates, it guides the driven pair 300b-3 to raise or lower the locking member. When raised, the constraint on the driven pair 300b-3 causes the locking member 300a to ultimately lock the lock head 301.

[0032] The specific arrangement of the linkage mechanism is designed based on the cylinder seat 300c, the cylinder 300d, and the lock head 301 whose assembly position remains unchanged. The cylinder 300d is located below the cylinder seat 300c, and the active pair 300b-2 is V-shaped. In this specific embodiment, there are two eccentric shafts, one of which is connected to the piston rod of the cylinder 300d. The positioning pair 300b-1 is directly fixed on the cylinder seat 300c. In this specific embodiment, the lock head 301 is located above the cylinder seat 300c. In this way, the locking member 300a can rotate and abut against the lock head 301 to complete the locking.

[0033] Preferably, the lock head 301 is a roller 301-b set on one end of the rod 301-a. The rod 301-a is horizontal. When locked, the locking member 300a is in close contact with the roller 301-b. The advantage of rolling friction reduces the wear on the locking member 300a.

[0034] In this specific embodiment, the locking part 300 is provided on the side of the fixed box 100, and the lock head 301 is provided on the side of the movable box 101.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
