Description

Technical Field

[0001] The utility model relates to the technical field of a ventilated mold test box, and more specifically, to a ventilated mold test box. Background Art

[0002] In the prior art, a ventilated mold test chamber is used to simulate the mold growth environment, wherein a certain air pressure is usually maintained inside the test chamber in order to simulate specific growth conditions. This internal pressure helps to ensure the stability of the test environment, thereby more accurately evaluating the growth response of the mold. However, existing ventilated mold test chambers have certain limitations in the exhaust process, especially in the inability to adjust the exhaust pressure. Since the internal air pressure may need to be adjusted according to different test stages during the test process, the unadjustable exhaust pressure becomes an obvious inconvenience.

[0003] The lack of exhaust pressure regulation function means that when the test chamber is vented, the outflow speed and pressure of the gas cannot be precisely controlled, which may cause the internal pressure to drop too quickly or become uneven, which will affect the stability of the test environment and the accuracy of the experimental results. In addition, if the internal pressure is not properly controlled, it may have an adverse effect on the growth conditions of mold. For example, if the pressure is too low, the mold growth rate may slow down or grow incompletely, and if the pressure is too high, the sealing performance of the test chamber may be damaged, which will affect the effectiveness of the overall test.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a ventilation type mold test box, which has the following

[0017] Beneficial effects:

[0018] 1. The adjustment mechanism provides precise internal pressure control function, allowing users to flexibly adjust the pressure according to experimental needs. Through the design of the air inlet pipe, adjustment pipe and nut sleeve, as well as the follower plate and positioning rod system that cooperates with the bellows and external pipe, the adjustment mechanism allows the sealing effect between the sealing plate and the sealing groove to be finely controlled by adjusting the pressure of the spring, thereby realizing dynamic adjustment of the internal pressure of the box, which is crucial for achieving accurate environmental simulation and ensuring the consistency of experimental conditions.

[0019] 2. The one-way mechanism ensures the one-way flow of gas during the pressure regulation process. The configuration of the one-way disk and the sealing plate, especially the application of the sealing ring on the one-way disk, ensures that the gas can only flow in the set direction. This not only protects the normal progress of the experiment, but also enhances the safety of the system and avoids test errors or equipment damage that may be caused by pressure reversal.

[0020] 3. The connection mechanism provides a stable and reliable connection method to ensure good fit and sealing between the adjustment mechanism and the box body. The design of the threaded tube and the fitting plate not only simplifies the installation process and improves assembly efficiency, but also ensures the sealing of the connection parts through the close contact of the fitting plate to prevent gas leakage, thereby maintaining the stability of the internal environment of the test box and the precise adjustment of the pressure, which is very beneficial for conducting high-standard mold growth experiments.

An adjusting mechanism is arranged on the box body 1, and the adjusting mechanism comprises an air inlet pipe 2, an adjusting pipe 3, a one-way mechanism, a nut sleeve 4, an insert sleeve 5, a bellows 6, an external pipe 7, a follower disc 8, a positioning rod 9, a spring 10 and a connecting mechanism. The air inlet pipe 2 is connected to the box body 1, and the connecting mechanism is cooperatively installed at the lower end of the adjusting pipe 3 and the side wall of the box body 1, the nut sleeve 4 is threadedly connected to the side wall of the adjusting pipe 3, the insert sleeve 5 is installed on the nut sleeve 4, one end of the bellows 6 is connected to the insert sleeve 5, and the other end of the bellows 6 is connected to the external pipe 7, the external pipe 7 is installed on the external device, the follower disc 8 is installed inside the insert sleeve 5, the positioning rod 9 is installed on the follower disc 8, the spring 10 is sleeved on the positioning rod 9, the one-way mechanism is installed on the adjusting pipe 3, and the one-way mechanism comprises a one-way The disk 11 and the sealing plate 12, the one-way disk 11 is installed in the adjusting tube 3, a sealing groove 13 is opened in the one-way disk 11, the sealing plate 12 fits in the sealing groove 13, a sealing ring 14 is coaxially provided on the sealing plate 12, the sealing ring 14 fits on the one-way disk 11, the adjusting tube 3 internal thread is provided with an adjusting ring 15, the adjusting ring 15 and the adjusting tube 3 are coaxially arranged, the spring 10 is pressed on the adjusting ring 15, a hexagonal sleeve 16 is arranged in the adjusting ring 15, a follower sleeve 17 is provided on the sealing plate 12, and the follower sleeve 17 is slidably connected to the hexagonal sleeve 16, a plurality of telescopic rods 18 are provided along the circumference of the sealing plate 12, and the length of each telescopic rod 18 is different, a plurality of insertion holes 19 are opened in the adjusting ring 15, and each insertion hole 19 corresponds to the telescopic rod 18 respectively, a positioning hole 20 is opened in the follower sleeve 17, and the positioning rod 9 is slidably connected in the positioning hole 20.

[0031] In this embodiment, when it is necessary to adjust the internal pressure, the rotation of the follower disk 8 can be driven by rotating the nut sleeve 4, and the rotation of the follower sleeve 17 can be driven by the snap connection between the positioning rod 9 and the positioning hole 20, and the hexagonal sleeve 16 is slidably connected to the follower sleeve 17, so the rotation of the adjustment ring 15 can be driven. Since the adjustment ring 15 is on the spring 10, and the nut sleeve 4 and the adjustment ring 15 are reversely threaded, the distance between the follower disk 8 and the adjustment ring 15 can be synchronously reduced or increased when the nut sleeve 4 is rotated, so the elastic force of the spring 10 can be changed, thereby changing the opening pressure of the sealing plate 12 and the sealing groove 13, and then the pressure in the box body 1 is adjusted.

[0032] See also Figure 3 As an implementation of the connecting mechanism: the connecting mechanism includes a threaded tube 21 and a fitting disk 22, the threaded tube 21 is installed on the adjusting tube 3, the fitting disk 22 is installed on the outside of the threaded tube 21, the threaded tube 21 is threadedly connected to the side wall of the box body 1, and the fitting disk 22 is in contact with the box body 1.

[0033] More specifically, when the follower disk 8 and the adjustment ring 15 are constantly moving away from each other, since the pressure is constantly decreasing, a portion of the insertion hole 19 can be sealed when the telescopic rod 18 is inserted into the insertion hole 19 each time it is opened, thereby avoiding the situation of too low pressure. Too low pressure means that all the internal air is discharged, thereby affecting the use effect.

[0034] In summary, when the overall equipment is in use or running: when it is necessary to adjust the internal pressure, first, the rotation of the follower disk 8 can be driven by rotating the nut sleeve 4, and the rotation of the follower sleeve 17 can be driven by the clamping connection between the positioning rod 9 and the positioning hole 20, and the hexagonal sleeve 16 is slidably connected to the follower sleeve 17, so it can drive the rotation of the adjustment ring 15. Since the adjustment ring 15 is on the spring 10, and the nut sleeve 4 and the adjustment ring 15 are reversely threaded, the distance between the follower disk 8 and the adjustment ring 15 can be synchronously reduced or increased when the nut sleeve 4 is rotated, so the elastic force of the spring 10 can be changed, thereby changing the opening pressure of the sealing plate 12 and the sealing groove 13, and then the pressure in the box body 1 is adjusted.

[0035] When the follower plate 8 and the adjustment ring 15 are always moving away from each other, since the pressure is always decreasing, a part of the insertion hole 19 can be sealed when the telescopic rod 18 is inserted into the insertion hole 19 each time it is opened, thereby avoiding the situation of too low pressure. Too low pressure means that all the air inside is discharged, thus affecting the use effect.
