Description

Technical Field

[0001] The utility model relates to the technical field of oxygen pressure detection, and specifically relates to an oxygen pressure detector. Background Technique

[0002] The oxygen pressure detector is used to monitor the pressure in the oxygen supply system in real time and ensure that the pressure is within the set safe range. This device can be used in medical respiratory systems, industrial gas supply systems or laboratory environments to ensure the stable and safe operation of the oxygen supply system. Oxygen enters the interior of the detector through a connecting pipe, and the pressure sensor converts the oxygen pressure into a readable pressure value, which is displayed through a screen or a dial. Generally, the oxygen pressure detector is directly threadedly connected to the oxygen gas pipeline. After locking, the orientation of the display panel is random, and it is rather troublesome to adjust the panel orientation.

[0003] Based on this, an oxygen pressure detector is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

Detailed implementation manners

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, as Figures 1-4 shown, an oxygen pressure detector includes an instrument housing 101. The instrument housing 101 is provided with a display module 103 for detecting and displaying the oxygen pressure. A rotatable connection block is provided at the lower end of the instrument housing 101 for enabling the pressure sensor in the oxygen pressure detector to contact oxygen. A protective cover 104 for protecting the display module 103 is provided at the front end of the instrument housing 101.

[0024] In this embodiment, the rotatable connection block can rotate by itself. One end of the rotatable connection block is threadedly connected to the oxygen pipeline, and the other end is connected to the instrument housing 101, so as to introduce oxygen into the oxygen pressure detector, realizing the convenience of adjusting the orientation of the display panel on the detector while fixing the detector.

[0025] In one embodiment, as Figures 2-4As shown in the figure, the rotating connection block includes an oxygen inlet 102 provided at the lower end of the instrument housing 101. At the lower end of the oxygen inlet 102, there is a socket hole 202. At the upper end of the socket hole 202, there is an oxygen input hole 201 communicating with the instrument housing 101. A socket post 303 is movably arranged in the socket hole 202. At the upper end of the socket post 303, a sealing head 301 is provided in the oxygen input hole 201. Between the socket post 303 and the oxygen inlet 102, there is an anti-disengagement structure to prevent the socket post 303 from disengaging from the socket hole 202. At the lower end of the socket post 303, a threaded connection head 304 is connected. The threaded connection head 304 is axially provided with a ventilation through hole 305, and the ventilation through hole 305 penetrates through the sealing head 301, the socket post 303 and the threaded connection head 304. Between the sealing head 301 and the oxygen input hole 201, there is a sealing structure. The socket post 303 can rotate and slide in the socket hole 202. The anti-disengagement structure restricts the sliding of the socket post 303 in the socket hole 202. The threaded connection head 304 is threadedly connected to the oxygen pipeline. Oxygen enters the oxygen input hole 201 through the ventilation through hole 305, and the oxygen pressure acts on the pressure sensor in the oxygen pressure detector. The sealing structure prevents the oxygen in the oxygen input hole 201 from leaking from the gap between the oxygen input hole 201 and the sealing head 301.

[0026] In one embodiment, as Figure 3 and Figure 4 shown, the anti-disengagement structure includes a through hole 402 provided on the oxygen inlet 102 and penetrating through the socket hole 202. A retaining pin 403 is slidably arranged in the through hole 402. There is a sliding damping between the retaining pin 403 and the through hole 402. At the position of the socket post 303 corresponding to the retaining pin 403, there is a circle of card slots 401 matching the retaining pin 403. After inserting the socket post 303 into the socket hole 202, insert the retaining pin 403 into the through hole 402 so that the retaining pin 403 is embedded in the card slots 401, preventing the socket post 303 from sliding in the socket hole 202 and making there be damping when the socket post 303 rotates in the socket hole 202.

[0027] In one embodiment, as Figure 3 shown, the sealing structure includes a sealing groove 306 coaxially arranged on the outside of the sealing head 301. In the sealing groove 306, there is a sealing ring 302 matching the gap between the sealing head 301 and the oxygen input hole 201, preventing the oxygen in the oxygen input hole 201 from leaking from the gap between the oxygen input hole 201 and the sealing head 301.

[0028] In one embodiment, as Figure 2 shown, between the protective cover 104 and the instrument housing 101, they are connected through a snap connection structure. The material of the transparent part of the protective cover 104 is usually acrylic or glass material, and it is easily damaged when being bumped. The snap connection structure facilitates removing the protective cover 104 from the instrument housing 101 for replacement.

[0029] In one embodiment, as Figure 1 and Figure 2 shown, the snap connection structure includes a snap groove 504 provided on the peripheral side of the front end of the instrument housing 101, and a matching snap post 503 is provided on the protection cover 104 at the position corresponding to the instrument housing 101. When disassembling the protection cover 104, first rotate the protection cover 104 counterclockwise to release the restriction of the snap post 503 from the snap groove 504, and then the protection cover 104 can be removed. When installing, first align the snap post 503 on the protection cover 104 with the snap groove 504 and insert it. After it is in place, rotate the protection cover 104 clockwise to make the snap post 503 stuck in the snap groove 504.

[0030] In one embodiment, as Figure 1 shown, anti-slip strips 501 are densely provided on the peripheral side of the protection cover 104 to prevent slipping when rotating the protection cover 104.

[0031] In one embodiment, as Figure 1 shown, a protective boss 502 is provided at the edge of the front end face of the protection cover 104 to protect the transparent part of the front end face of the protection cover 104.

[0032] The above embodiment discloses an oxygen pressure detector. Among them, the threaded connection head 304 is threadedly connected to the oxygen pipeline. Oxygen enters the oxygen input hole 201 through the ventilation perforation 305, and the oxygen pressure acts on the pressure sensor in the oxygen pressure detector. The insertion post 303 can rotate and slide in the insertion hole 202. The snap pin 403 is embedded in the card slot 401 to prevent the insertion post 303 from sliding in the insertion hole 202 and make the insertion post 303 have damping when rotating in the insertion hole 202, realizing that after the oxygen pressure detector is fixed, it is convenient to adjust the orientation of the display panel of the detector.

[0033] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
