[Industrial applications]

 The present invention relates to an inspection port, more specifically, a stainless steel cosmetic inspection port for waterproof and dustproof. In recent years, as the number of stainless steel makeup inspection openings such as various pipes and electrical equipment on the streets and floors has increased, the location where high-level instruments and equipment are likely to generate moisture, temperature, dust, etc., becomes an easy-to-see installation location. For this reason, a waterproof and dustproof stainless steel makeup inspection port is required to have a structure that is aesthetically pleasing and safe, and has a structure that makes it easy to lift the middle frame lid, even though the period from inspection to inspection is long. . It is necessary to popularize the stainless steel inspection port of this invention as an industrial application field. 0002

[Prior art]

 As shown in Fig. 3, the conventional waterproof and dustproof stainless steel makeup inspection port has a structure to prevent sewage and dust from being formed on the lower surfaces of the outer frame and the middle frame lid. It hardens in the gap between the middle frame lid and it is difficult to lift the middle frame lid only by the handle of the middle frame lid at the time of inspection, which requires labor and tools. Also, as shown in Fig. 4, there is a structure in which the contact sides of the outer and middle frame lids are tapered to prevent sewage and dust, but if it is used for a long period after installation, the sewage will harden into a minute gap and Stuck due to the passage of heavy objects, and it was difficult to inspect, and both of them had damaged the cosmetic lid, handle, etc. 0003

[Problems to be solved by the device]

 However, the upper surface support of the middle frame lid of the stainless steel cosmetic inspection port of the present invention is waterproof and dustproof on the upper side with the upper packing of the outer frame, and the double safety that the inner frame lid support packing is arranged on the lower surface of the outer frame. A protective stainless steel cosmetic inspection door has never been seen before. This stainless steel makeup inspection port has a structure that does not allow infiltration of dirty water, dust, etc., and even if the inspection period is long, there is no hardened material that will become a resistance, so it is safe to carry in heavy vehicles. At the time of inspection, there is no change from the beginning, and the inner frame lid can be easily lifted without damage, facilitating inspection. 0004

【Example】

A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a part of the makeup point inspection mouth of the present invention, in which 1 is a stainless steel makeup inspection mouth, and makeup inspection mouth 1 The support upper surface packing 8 is provided, and the outer frame 2 and 6 and the inner frame lid 4 and 5 support the upper surface for waterproofing, dustproofing and support the inner frame lid 4, and the lower surface of the outer frame 2 is provided with the inner frame lid receiver 7. , The lower surface support packing 9 is arranged on the upper surface, and the lower surface waterproof and dustproof and the middle frame lid 4 are received. Since only the packing 9 does not allow sewage and dust to enter and no resistance hardened material is generated in the gap between the outer frame 2 and the inner frame lid 4, even after a long inspection period, it is the same as during construction. The frame lid 4 can be easily lifted by the handle 10 of the middle frame lid 4. Also, because of the double support structure, the inner frame lid is not damaged, and it has the features that it does not lose its aesthetic appearance over the years. 0005

[Effect of device]

 As explained above, the stainless steel makeup inspection port of the present invention does not cause an obstacle during the long period of time from the inspection after installation to the inspection because there is no place where hardened products caused by dust, dirty water, etc. come into close contact. , The inspection is facilitated and the inspection of the instruments and instruments inside the inspection port is protected from dust, dirty water, etc., resulting in labor saving of the inspection. In addition, it can be used not only for makeup inspection port but also for lids of various tanks, and the inspection port material can be made of metal, plastic, ceramic, etc. and can be installed regardless of the shape of the inspection port.
