DETAILED DESCRIPTION

[0023] ​The following specific embodiments illustrate the embodiments of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosed content. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] In combination with reference to Figures 1-4 The present application provides a medical oxygen supply equipment, which comprises a support frame 1, and a main oxygen supply tank 2 and a vice oxygen supply tank 3 are fixedly penetrated on the support frame 1.

[0025] The main oxygen supply tank 2 can be used as a main oxygen supply tank body, and the vice oxygen supply tank 3 can be used as a standby tank for the main oxygen supply tank 2.

[0026] In the embodiment, the main oxygen supply tank 2 and the vice oxygen supply tank 3 are connected in communication, and one connecting pipe 9 is fixedly connected in communication with the outer surfaces of the main oxygen supply tank 2 and the vice oxygen supply tank 3, and the pair of connecting pipes 9 are connected through flanges.

[0027] The on-off of the communication between the main oxygen supply tank 2 and the vice oxygen supply tank 3 can be realized by controlling the on-off of the connecting pipe 9, so that when it is necessary to expand the oxygen storage volume of the main oxygen supply tank 2, the vice oxygen supply tank 3 can be connected in communication with the main oxygen supply tank 2, and vice versa, and the vice oxygen supply tank 3 is closed.

[0028] In the embodiment, the main oxygen supply tank 2 is provided in a single-opening structure, and the vice oxygen supply tank 3 is provided in a double-opening structure, one end of the main oxygen supply tank 2 is flange-connected with a cover plate one 13, and both ends of the vice oxygen supply tank 3 are flange-connected with a cover plate two 14.

[0029] In the embodiment, the top of the main oxygen supply tank 2 is fixedly connected in communication with an oxygen inlet pipe 4.

[0030] The oxygen inlet pipe 4 can collect the prepared oxygen into the main oxygen supply tank 2.

[0031] The cover plate one 13 and the cover plate two 14 can be disassembled to seal the openings of the main oxygen supply tank 2 and the vice oxygen supply tank 3, so as to assemble the tank structure, and the cover plate one 13 and the cover plate two 14 are both provided with air holes.

[0032] In the embodiment, one explosion-proof strip window 10 is fixedly embedded on the main oxygen supply tank 2 and the vice oxygen supply tank 3, and the explosion-proof strip window 10 is provided with a capacity scale line 11.

[0033] The explosion-proof strip window 10 is provided in a strip structure, so that the internal structure of the oxygen supply tank can be conveniently observed, and the capacity scale line 11 indicates the volume of the oxygen storage of the main oxygen supply tank 2 and the vice oxygen supply tank 3.

[0034] In this embodiment, the main gas supply tank 2 is slidably connected with a sealing piston one 5, and the auxiliary gas supply tank 3 is slidably connected with a sealing piston two 6.

[0035] When the volume of the oxygen storage in the main gas supply tank 2 needs to be adjusted, the sealing piston one 5 can be controlled to move up and down in the main gas supply tank 2, so that the sealing piston one 5 can adjust the volume of the oxygen storage in the main gas supply tank 2. Similarly, the sealing piston two 6 can achieve the same principle as the sealing piston one 5, so that the sealing piston two 6 can conveniently adjust the volume of the oxygen storage in the auxiliary gas supply tank 3.

[0036] In this embodiment, the sealing piston one 5 is fixedly penetrated with an oxygen outlet pipe 7, one end of the oxygen outlet pipe 7 movably penetrates through the cover plate one 13 and is fixedly connected with an extension pipe 71.

[0037] After the sealing piston one 5 adjusts the volume of the oxygen storage in the main gas supply tank 2, the position of the oxygen outlet pipe 7 can conveniently supply the oxygen in the main gas supply tank 2 to the outside, the extension pipe 71 can extend the pipe structure at one end of the oxygen outlet pipe 7, and the oxygen outlet end of the extension pipe 71 can be connected with a flexible pipe structure to adapt the action of the extension pipe 71, and the flexible pipe can be conveniently connected with an external oxygen connection structure.

[0038] In this embodiment, the support frame 1 is provided with a lifting mechanism 8 for controlling the lifting of the sealing piston one 5 and the sealing piston two 6, the lifting mechanism 8 includes a lifting device one 81, the lifting device one 81 is fixedly connected to the inner top of the support frame 1, the output end of the lifting device one 81 is fixedly connected with a lifting plate 82, the lifting plate 82 is fixedly connected with four support rods 83, and the four support rods 83 are fixedly connected with the sealing piston one 5 and the sealing piston two 6 two by two, wherein two support rods 83 movably penetrate through the cover plate one 13, and the other two support rods 83 movably penetrate through the cover plate two 14 located at the bottom.

[0039] In use, the lifting device one 81 adopts a self-locking type lifting motor, which drives the lifting plate 82 to move up and down, and the lifting plate 82 can drive the sealing piston one 5 and the sealing piston two 6 to perform compression action through the position synchronization of the support rods 83, so that the sealing piston one 5 and the sealing piston two 6 can respectively adjust the volume of the oxygen storage in the main gas supply tank 2 and the auxiliary gas supply tank 3.

[0040] It is worth noting that because the sealing piston one 5 and the sealing piston two 6 share the drive of the lifting device one 81, the sealing piston one 5 and the sealing piston two 6 will move synchronously, and when the oxygen storage volume of the medical oxygen supply equipment needs to be adjusted, and the auxiliary gas supply tank 2 is not used to expand the volume of the main gas supply tank 2, at this time, the connecting pipe 9 connected with the main gas supply tank 2 and the auxiliary gas supply tank 3 should be in a connected and opened state, so that the sealing piston two 6 can move normally under standard pressure.

[0041] When the auxiliary oxygen tank 2 is needed to expand the oxygen storage volume, the sealing piston one 5 should be lowered in the main oxygen tank 2, and the synchronous movement of the sealing piston two 6 and the sealing piston one 5 can also expand the oxygen storage volume of the auxiliary oxygen tank 3, so as to improve the efficiency of expanding the oxygen storage volume.

[0042] In the embodiment, the lifting plate 82 is fixedly connected with a sliding seat 12 at both ends, and the sliding seat 12 is slidingly connected to the inner side of the support frame 1.

[0043] The sliding seat 12 can be used to stabilize the track of the lifting plate 82.

[0044] In the embodiment, the lifting device two 15 is fixedly connected to the top cover plate two 14, the output end of the lifting device two 15 is movably connected through the cover plate two 14 and fixedly connected with the sealing piston three 16, and the sealing piston three 16 is slidingly connected in the auxiliary oxygen tank 3.

[0045] Since the auxiliary oxygen tank 3 is a secondary oxygen tank of the main oxygen tank 2, in order to compensate for the stroke limitation of the sealing piston two 6 corresponding to the lifting mechanism 8 when expanding the oxygen storage volume of the main oxygen tank 2, the lifting device two 15 adopts a self-locking lifting motor, and the compression movement of the sealing piston three 16 in the auxiliary oxygen tank 3 driven by the lifting device two 15 can quickly adjust the size of the oxygen storage volume of the auxiliary oxygen tank 3 to the main oxygen tank 2.

[0046] It is worth mentioning that the cover plate one 13 and the cover plate two 14 are respectively detachably connected to the main oxygen tank and the auxiliary oxygen tank 3, and the positions of the sealing piston one 5, the sealing piston two 6 and the sealing piston 16 are connected by the cover plate one 13 and the cover plate two 14, so that the structure for adjusting the oxygen storage volume and the oxygen tank 2 can be easily assembled.

[0047] In the embodiment, a valve is arranged on the oxygen inlet pipe 4, the extension pipe 71 and the connecting pipe 9.

[0048] The valve is used to control the on-off of the oxygen supply in the pipe structure.
