Description

Technical Field

[0001] The utility model relates to the technical field of oxygen pressure reducers, in particular to a quick-connection structure of an oxygen pressure reducer. Background Art

[0002] Oxygen pressure reducers are generally pressure reducing devices for bottled gas. When the inlet pressure and outlet flow rate change, the outlet pressure is guaranteed to remain stable. The increase in the low pressure gauge reading may indicate potential danger and hidden danger. When the oxygen pressure reducer needs to supply oxygen, it is generally necessary to connect the device to achieve this.

[0003] The existing quick-connect structure of the oxygen pressure reducer is generally aimed at the existing oxygen pressure reducer device, which cannot display the oxygen content in the cylinder. In practical applications, the problem of delayed treatment caused by temporary replacement of the oxygen cylinder due to insufficient oxygen may occur. For example, an oxygen pressure reducer device disclosed in the authorized Chinese patent CN212997881 U can display the residual oxygen content in the oxygen cylinder through the use of a pressure reducing valve body, a control knob, a switching part, an air inlet pipe, an air outlet pipe, a first connecting pipe, a second connecting pipe, an inner cavity, a first pressure gauge, a second pressure gauge connected, an oxygen cylinder, a ventilator switching valve and a ventilator, so as to avoid the problem of delayed treatment caused by temporary replacement of the oxygen cylinder due to insufficient oxygen.

[0004] However, the oxygen pressure reducer device in the above cited document has a relatively complicated operation to realize the connection function, and cannot realize quick connection. For the oxygen pressure reducer used in emergency situations, there are requirements for the connection speed. Therefore, in order to avoid the delay of treatment due to the connection speed problem, a quick connection structure of the oxygen pressure reducer is proposed to solve the above problem.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

[0030] Through the mutual cooperation between the oxygen pressure reducer body 2, the quick connecting structure 300, the hose 4 and the ventilator 5 on the oxygen steel tank 1, a function of quickly connecting the oxygen steel tank 1 and the ventilator 5 can be provided, thereby improving the connection speed and avoiding the situation where the treatment is delayed due to the connection speed problem, thereby effectively improving the connection speed of the existing oxygen pressure reducer.

[0031] In this embodiment, the quick connection structure 300 is a structure for quickly connecting the oxygen tank 1 and the breathing machine 5 .

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the quick connection structure 300 includes a cannula 301 fixedly connected to the oxygen pressure reducer body 2 and two handles 302 respectively fixedly connected to the outside of the cannula 301;

[0033] The interior of the cannula 301 is provided with a sliding cavity 303, and the number of the sliding cavities 303 is two and they are distributed in a mirror-symmetrical manner;

[0034] A limit assembly and two adjustment blocks 305 respectively connected to the outside of the limit assembly are installed in the sliding cavity 303. An oxygen supply pipe 308 is fixedly connected to the side of the cannula 301 away from the oxygen pressure reducer body 2. A connecting sealing pipe 315 is slidably connected to the outside of the oxygen supply pipe 308. The outside of the oxygen supply pipe 308 is tightly fitted with the inner side of the connecting sealing pipe 315. A connecting pipe 309 is fixedly connected to the side of the connecting sealing pipe 315 away from the oxygen supply pipe 308. Two sets of mirror-symmetrical fastening assemblies are installed on the connecting sealing pipe 315, and a convex slider 313 is connected to one side of the fastening assembly.

[0035] It should be noted that an adjustment groove 306 for the adjustment block 305 to slide in is provided on the inner wall of the sliding cavity 303 so as to make the adjustment block 305 move more stably.

[0036] It can be understood that the limiting assembly includes a moving block 3041, a No. 1 return spring 3042 and a limiting bevel block 3043; the outer side of the moving block 3041 slides on the inner side of the sliding cavity 303, one end of the No. 1 return spring 3042 is fixedly connected to the side of the moving block 3041 away from the limiting bevel block 3043, and the other end is fixedly connected to the inner wall of the sliding cavity 303, and one side of the limiting bevel block 3043 is fixedly connected to the end of the moving block 3041 away from the No. 1 return spring 3042, so as to perform limiting movement after the oxygen supply tube 308 is inserted into the connecting sealing tube 315.

[0037] In addition, the fastening assembly includes a sliding rod 3101, a No. 2 return spring 3102 and a push plate 3103; one end of the sliding rod 3101 passes through the connection sealing tube 315 and is connected to the limiting inclined block 3043, and the other end is fixedly installed on one side of the push plate 3103, the inner side of the No. 2 return spring 3102 is sleeved on the outer side of the sliding rod 3101, and the No. 2 return spring 3102 is located below the connection sealing tube 315, and one side of the convex slider 313 is fixedly connected to one side of the push plate 3103;

[0038] A sliding hole 312 for sliding the sliding rod 3101 is provided on one side of the connecting sealing tube 315 , so as to facilitate the release of the restriction on the insertion tube 301 .

[0039] In this embodiment, a through hole 311 for the limiting bevel block 3043 to pass through is opened on one side of the sliding rod 3101, and a slot 307 for engaging with the sliding rod 3101 is opened on the side of the limiting bevel block 3043 away from the connecting sealing tube 315, in order to further improve the stability of the limit.

[0040] It should also be noted that a convex groove 314 for the convex sliding block 313 to slide against is provided on the outer side of the connecting tube 309 in order to improve the stability of the movement of the pushing plate 3103 .

[0041] It should also be noted that sealing rings are abutted against each other on opposite sides of the cannula 301 and the connecting sealing tube 315 to prevent oxygen leakage.

[0042] The working principle of the above embodiment is:

[0043] During installation, first insert the oxygen supply tube 308 fixed on the cannula 301 into the connecting sealing tube 315. During the insertion and movement, the limiting bevel block 3043 contacts the sliding rod 3101, which will push the limiting bevel block 3043 to move in the direction close to the cannula 301, and at the same time squeeze the moving block 3041 to move in the direction close to the cannula 301. Because the moving block 3041 can only move in the sliding cavity 303 under the sliding connection between the adjusting block 305 and the adjusting groove 306, and the No. 1 return spring 3042 is squeezed by the moving block 3041. When the moving block 3041 moves to the sliding cavity, the return spring 3042 is compressed. 303, at this moment, the No. 1 reset spring 3042 resets the moving block 3041 to move, and the limiting bevel block 3043 moves accordingly, so that the slot 307 thereon is engaged with the sliding rod 3101, and under the elastic potential energy thrust of the No. 2 reset spring 3102 and the sliding connection between the convex sliding block 313 and the convex slot 314, the pushing plate 3103 is stably pushed to move away from the cannula 301, and the sliding rod 3101 moves along with it and is tightened, so that the oxygen supply tube 308 and the connecting sealing tube 315 can be connected more tightly. At this time, the oxygen reducer body 2 and the ventilator 5 are opened to output the oxygen in the oxygen steel tank 1.

[0044] Compared with the prior art: the quick connection structure of the oxygen pressure reducer can provide a function of quickly connecting the oxygen steel tank 1 and the ventilator 5 through the mutual cooperation between the oxygen pressure reducer body 2 on the oxygen steel tank 1, the quick connection structure 300, the hose 4 and the ventilator 5, thereby improving the connection speed and avoiding the situation where the treatment is delayed due to the connection speed problem, thereby effectively improving the connection speed of the existing oxygen pressure reducer and solving the problem of poor connection speed of the existing oxygen pressure reducer.
