[0025] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a vital capacity measuring instrument for physical health test, comprising a measuring instrument body 10, a fixing tube 11 is fixedly connected inside the right side of the measuring instrument body 10, a hose 12 is fixedly connected to one end of the fixing tube 11, an air intake pipe 15 is fixedly connected to one end of the hose 12, a mouthpiece 16 is slidably connected inside the upper end of the air intake pipe 15, a sleeve 14 is fixedly connected to the air intake pipe 15, and a rubber block 17 is arranged at the upper end of the air intake pipe 15;
[0026] A sealing sleeve 18 is provided at the top of the sleeve 14, a blowing nozzle 16 is provided inside the rubber block 17 and the sealing sleeve 18, a bolt 19 is threadedly connected to the left side of the sleeve 14, a handle 13 is fixedly connected to the right side of the sleeve 14, and an adjustment component is fixedly connected to the bottom of the measuring instrument body 10;
[0027] The adjustment component includes a telescopic frame 3, which is fixedly connected to the bottom of the measuring instrument body 10. The front side of the telescopic frame 3 is provided with evenly distributed sockets 4, and the front side of the telescopic frame 3 is provided with an insertion rod 5, which is slidably connected to the inside of the socket 4.
[0028] By pulling out the insertion rod 5 and separating it from the insertion hole 4, the telescopic frame 3 is pulled upward and its height is adjusted to a suitable height. When the mouthpiece 16 needs to be replaced, the bolt 19 is turned to separate it from the sleeve 14, and the mouthpiece 16 is pulled upward to separate it from the air intake pipe 15 and replaced; and the mouthpiece 16 is made to fit closely to the air intake pipe 15 through the rubber block 17 and the sealing sleeve 18, so that the mouthpiece 16 can be replaced quickly and conveniently, and it is fixed so that the mouthpiece 16 fits closely to the air intake pipe 15 to prevent air leakage.
[0029] Reference Figure 1 , Figure 3 and Figure 4 The right front side of the measuring instrument body 10 is fixedly connected with a connecting piece 20, the inner rear side of the connecting piece 20 is rotatably connected with a first arc plate 21, the inner front side of the connecting piece 20 is rotatably connected with a second arc plate 23, the rear side of the second arc plate 23 is fixedly connected with an insert block 22 at the upper and lower sides, and a fixed block 8 is arranged inside the insert block 22;
[0030] Springs 25 are fixedly connected to the left and right sides of the fixed block 8, one end of the spring 25 is fixedly connected to a clamping block 24, a sliding groove 26 is provided inside the insert block 22, the clamping block 24 is slidably connected inside the sliding groove 26, and the insert block 22 and the clamping block 24 are slidably connected inside the first arc plate 21.
[0031] The first arc plate 21 and the second arc plate 23 are rotated inside the connecting member 20 to fix the hose 12. When the first arc plate 21 and the second arc plate 23 are rotated and fitted together, the insert block 22 drives the clamping block 24 to move and insert into the clamping groove provided inside the first arc plate 21. While the clamping block 24 is squeezed through the clamping groove, the spring 25 is squeezed to generate a rebound force. When the clamping block 24 is no longer squeezed, the rebound force of the spring 25 causes the clamping block 24 to be inserted into the clamping groove to fix the hose 12.
[0032] Reference Figure 1 A fixing ring 6 is arranged on the outside of the telescopic frame 3, a placement box 7 is fixedly connected to the front side of the fixing ring 6, and a storage box 9 is slidably connected to the right side of the inside of the placement box 7; the bottom of the telescopic frame 3 is fixedly connected to a base 1, and universal wheels 2 are fixedly connected to the four bottom corners of the base 1.
[0033] By fixing and supporting the telescopic frame 3 via the base 1 , the fixing ring 6 can fix and support the storage box 9 , so that the storage box 9 can store the disposable mouthpieces 16 , and the measuring instrument can be moved via the universal wheels 2 .
[0034] Working principle:
[0035] When the device needs to be used, after the previous tester has finished the test, the bolt 19 is turned to separate it from the sleeve 14, and the mouthpiece 16 is pulled out of the air inlet pipe 15, and the disposable mouthpiece 16 placed in the storage box 9 is taken out, replaced and reinserted into the air inlet pipe 15, and fixed by the bolt 19, and the mouthpiece 16 is closely attached to the air inlet pipe 15 under the action of the rubber block 17 and the sealing sleeve 18, so that the mouthpiece 16 can be quickly and conveniently replaced and fixed, and the mouthpiece 16 is closely attached to the air inlet pipe 15 to prevent air leakage and affect the measurement effect;
[0036] When the device is not used, the hose 12 is placed inside the first arc plate 21 and the second arc plate 23, and the second arc plate 23 is pushed so that the insert block 22 drives the clamping block 24 to move and insert into the clamping slot of the first arc plate 21. When the insert block 22 is inserted into the clamping slot, the clamping block 24 is pressed, so that the clamping block 24 presses the spring 25 and resists the fixing block 8, so that the spring 25 generates a rebound force.
[0037] When the block 24 is no longer squeezed, it is inserted into the slot by the rebound force of the spring 25 to fix the hose 12 , thereby fixing the hose 12 when the measuring instrument is not in use to prevent it from falling and causing dust or debris to enter the hose 12 .
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
