[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is a detailed description of the present invention in conjunction with the specific implementation methods and with reference to the attached drawings. Figure 1-3 , the utility model is further described in detail. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] The utility model provides a trachea fixing bracket for a differential pressure gauge in a clean area, comprising a silicone patch 7 fixed on a wall, and the silicone patch 7 is glued to the wall. A silicone fixing tube 1 is provided at the center of the silicone patch 7, and the silicone fixing tube 1 is integrally formed with the silicone patch 7. The silicone fixing tube 1 corresponds to the trachea placement hole on the wall, and the silicone fixing tube 1 shrinks at one end away from the silicone patch 7. The silicone fixing tube 1 has an interference fit with the trachea, which plays a role in fixing the trachea. The end of the silicone fixing tube away from the silicone patch is set downward, and the corresponding end of the trachea set in the silicone fixing tube is also set downward to prevent dust from falling into the trachea.

[0022] The trachea passes through the trachea installation hole through the trachea fixing bracket and is connected to the differential pressure gauge in another room, thereby realizing air pressure control of the two rooms. At the same time, the silicone fixing tube 1 and silicone patch 7 can reduce the occurrence of sanitary dead corners and ensure the cleanliness of the clean area of ​​the workshop.

[0023] The silicone patch 7 is provided with a date recording unit. The date recording unit includes a month track 6, which is evenly divided into 12 parts and marked with the name of each month. An indicator plate 5 is slidably provided on the month track 6, through which the name of the month can be clearly seen. The indicator plate 5 is a magnifying glass with a light-colored indicator color. When the differential pressure gauge is inspected, the indicator plate 5 can be slid to the month of inspection for easy recording.

[0024] The silicone patch 7 is provided with a differential pressure gauge status indication unit. The differential pressure gauge status indication unit includes a status track, the base of which is divided into a qualified indication block 4 and an unqualified indication block 2. A status shield 3 is slidably provided on the status track, and the status shield 3 is in an opaque state. The status shield 3 is longer than the length of the qualified indication block 4 or the unqualified indication block 2. When in use, the status shield 3 can completely cover the qualified indication plate or the unqualified indication plate. The status shield is provided with a push groove for easy pushing. The status of the differential pressure gauge is marked by adjusting the position of the status shield on the status track, which is convenient and quick to use.

[0025] The utility model realizes the stable installation of the trachea on the trachea fixing bracket and connects with the differential pressure gauge through the trachea installation hole through the arrangement of the silicone patch and the silicone fixing tube. The utility model has a simple structure and no sanitary dead corners, and can ensure the cleanliness of the workshop.
