Description
Technical Field
[0001] The utility model relates to the technical field of detection and protection, in particular to a dead space performance tester for protective products. Background Art
[0002] A dead space performance tester for protective products is an instrument specifically used to detect the dead space performance of protective products, such as gas masks, respirators, etc. Dead space refers to the part of the space that is not in communication with the outside air during use. The gas in this part of the space cannot be effectively utilized by the user, which may lead to problems such as insufficient oxygen or an increase in the concentration of harmful gases.
[0003] Most of the existing testers directly test the protective products. However, this testing method may not fully simulate the actual use conditions. During actual use, the protective products may show different protection effects due to factors such as head movement and impacts at different angles. Measuring the protective products without using a human skull mold may cause deviations in the subsequent dead space performance test data. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides a dead space performance tester for protective products.
[0005] The utility model is implemented by the following technical solutions: A dead space performance tester for protective products, including a test box body. One side of the upper surface of the test box body is fixedly connected with a telescopic frame, and a display instrument body is fixedly connected to the surface of the telescopic frame. On the other side of the upper surface of the test box body, a mold assembly is arranged;
[0006] The mold assembly includes a mold base plate. The bottom of the mold base plate is fixedly connected to the other side of the upper surface of the test box body. One side of the upper surface of the mold base plate is fixedly connected with a main bearing, and a main mold is fixedly connected to the surface of the main bearing. The other side of the upper surface of the mold base plate is fixedly connected with a secondary bearing, and a secondary mold is fixedly connected to the surface of the secondary bearing. Exhaust pipes are fixedly connected to the outer surfaces of the main mold and the secondary mold.
[0007] Through the above technical solutions, by using a telescopic frame whose position can be adjusted, the operator can conveniently test the protective products without directly contacting the test box body. And by setting a main mold and a secondary mold, the operator can put the protective products on the surface of the molds. Since the outer shape of the molds is the same as that of the human skull, the test can be carried out under conditions close to the actual use environment, so as to obtain data closer to the actual use effect. At the same time, two molds of different sizes enable the operator to measure two different types of protective products simultaneously, thereby improving the test efficiency of the protective products.
[0008] As a further improvement of the above solution, an assembly support plate is fixedly connected to the inner wall of the test box body, and protective seats are fixedly connected to both sides of the lower surface of the assembly support plate.
[0009] Through the above technical solution, the assembly support plate is fixedly connected to the inner wall of the test box body, making the air pump more stable during the test process, avoiding displacement caused by vibration or external force, and thus ensuring the accuracy and reliability of the test.
[0010] As a further improvement of the above solution, the bottom of the protective seat is fixedly connected to the inner bottom wall of the test box body, and a main air pump is fixedly connected to one side of the upper surface of the assembly support plate.
[0011] Through the above technical solution, fixing the protective seat on the inner bottom wall of the test box body can provide a stable foundation, helping to support the upper assembly support plate and main air pump, and reducing vibration and unstable factors during the working process.
[0012] As a further improvement of the above solution, a secondary air pump is fixedly connected to the other side of the upper surface of the assembly support plate, and the secondary air pump is connected to the secondary mold.
[0013] Through the above technical solution, the secondary air pump can directly provide power for the secondary mold without the need for transmission through other equipment or pipelines, which can improve work efficiency.
[0014] As a further improvement of the above solution, the main air pump is connected to the main mold.
[0015] Through the above technical solution, compared with the traditional air pump system, the direct connection between the main air pump and the main mold can reduce air flow loss, thus saving energy.
[0016] As a further improvement of the above solution, an adapter seat is fixedly connected to the lower surface of the test box body, and the number of adapter seats is four, which are respectively fixedly connected to the four corners of the lower surface of the test box body.
[0017] Through the above technical solution, the four adapter seats are fixed at the four corners of the lower surface of the test box body, which can increase the stability of the test box body and prevent tilting or shaking during use.
[0018] As a further improvement of the above solution, moving wheels are arranged inside the adapter seat, and a sealing cover is clamped on the outer surface of the test box body.
[0019] Through the above technical solution, the arrangement of the moving wheels enables the test box body to be conveniently moved and positioned, which is very beneficial for scenarios where tests or experiments need to be carried out at different locations.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0021] By providing a mold assembly in the present utility model, personnel can first use a telescopic frame whose position can be adjusted to facilitate the testing of protective products without directly contacting the test box. Subsequently, by providing a main mold and a sub-mold, personnel can put the protective product on the surface of the mold. Since the outer shape of the mold is consistent with that of the human skull, the test can be carried out under conditions close to the actual use environment, thereby obtaining data closer to the actual use effect. At the same time, two molds of different sizes enable personnel to measure two different types of protective products simultaneously, thus improving the testing efficiency of protective products.
