Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0031] Embodiment one

[0032] The present application provides a technical solution: a convenient-to-adjust oxygen cylinder transportation and supporting device, comprising a first supporting frame 1 and a second supporting frame 2, a first supporting plate 21 for containing oxygen cylinders is fixedly connected to the second supporting frame 2, a first circular ring 3 is fixedly connected to the second supporting frame 2, four placing grooves are formed in the first circular ring 3 and four piston cylinders 31 are fixedly connected through the four placing grooves, a sealing plug 34 is slidingly connected to each piston cylinder 31, a piston rod 33 is fixedly connected to each sealing plug 34, a wedge block 32 is fixedly connected to each piston rod 33, a first spring 35 is placed in each piston cylinder 31, and the two ends of each first spring 35 are fixedly connected to the corresponding sealing plug 34 and piston cylinder 31, respectively, and an adaptive mechanism for self-adaptive fixing according to the diameter of the oxygen cylinder is arranged on the second supporting frame 2.

[0033] In use, the oxygen cylinder is placed at the first circular ring 3, then the oxygen cylinder is in contact with the four wedge blocks 32, and the four wedge blocks 32 are moved away from the oxygen cylinder, then the oxygen cylinder continues to slide downward along the second circular ring 52 and the third circular ring 5, and then the oxygen cylinder is in contact with the first supporting plate 21.

[0034] The adaptive mechanism further comprises two second circular rings 52 fixedly connected to the second supporting frame 2, a hexagonal groove 56 is formed in each second circular ring 52, six sliding blocks 54 are slidingly connected to each hexagonal groove 56, a fixed block 51 is fixedly connected to each sliding block 54, and a slide rod 53 is fixedly connected to each fixed block 51.

[0035] The adaptive mechanism further comprises two third circular rings 5 and a connecting rod 58, two rotating grooves are formed in the second supporting frame 2 and the third circular ring 5 is rotatably connected through the two rotating grooves, six inclined sliding grooves 55 are formed in each third circular ring 5, each inclined sliding groove 55 is slidingly connected to the corresponding slide rod 53, a supporting block 57 is fixedly connected to each third circular ring 5, and the two supporting blocks 57 are fixedly connected through the connecting rod 58.

[0036] The adaptive mechanism further comprises a first arc-shaped piston cylinder 4 fixedly connected to the second support frame 2, a first arc-shaped sealing plug 42 slidably connected to the first arc-shaped piston cylinder 4, a first arc-shaped piston rod 41 fixedly connected to the first arc-shaped sealing plug 42, the first arc-shaped piston rod 41 being fixedly connected to the support block 57, a second spring 43 sleeved on the first arc-shaped piston rod 41, both ends of the second spring 43 being fixedly connected to the first arc-shaped sealing plug 42 and the first arc-shaped piston cylinder 4 respectively, and a circular truncated cone 45 slidably connected to the first arc-shaped piston cylinder 4 through a through hole formed in the first arc-shaped piston cylinder 4.

[0037] The adaptive mechanism further comprises an air inlet pipe 36 and an air outlet pipe 37, the piston cylinder 31 being fixedly communicated with the outside through the air inlet pipe 36, the piston cylinder 31 being fixedly communicated with the first arc-shaped piston cylinder 4 through the air outlet pipe 37, and the air inlet pipe 36 and the air outlet pipe 37 each being fixedly communicated with a first one-way valve 38.

[0038] When the four wedge blocks 32 slide away, the piston rods 33 thereon drive the sealing plugs 34 to slide towards one end close to the air inlet pipe 36, so that the gas in the first arc-shaped piston cylinder 4 is discharged into the first arc-shaped piston cylinder 4 through the air outlet pipe 37, thereby driving the first arc-shaped sealing plug 42 in the first arc-shaped piston cylinder 4 to slide towards an end away from the air outlet pipe 37, so that the support block 57 drives the third circular ring 5 to rotate along the rotating groove on the second support frame 2, since the sliding block 54 on the fixed block 51 is slidably connected to the first hexagonal groove 56 on the second circular ring 52, and the inclined sliding groove 55 on the third circular ring 5 is slidably connected to the sliding rod 53 on the fixed block 51, the six fixed blocks 51 slide, thereby fixing and supporting the oxygen cylinder, as shown in the figure, which is the sealing state of the six fixed blocks 51. Figure 6

[0039] And since the diameter of the oxygen cylinder is different, the sliding stroke of the piston rod 33 driven by the wedge block 32 is different.

[0040] When the diameter of the oxygen cylinder is larger, the sliding stroke of the piston rod 33 driven by the wedge block 32 is longer, so that more gas in the piston cylinder 31 is delivered into the first arc-shaped piston cylinder 4 through the air outlet pipe 37, thereby the sliding distance of the first arc-shaped piston rod 41 driven by the first arc-shaped sealing plug 42 in the first arc-shaped piston cylinder 4 is longer, so that the rotating distance of the third circular ring 5 driven by the support block 57 is larger, thereby the sliding distance of the six fixed blocks 51 is longer, thereby the fixed blocks 51 can fix and support the oxygen cylinder with larger diameter, and the interference between the oxygen cylinder and the fixed blocks 51 is avoided.

[0041] ​When the diameter of the oxygen cylinder is smaller, the sliding stroke of the wedge 32 driving the piston rod 33 is shorter, so that the gas in the piston cylinder 31 is delivered to the first arc-shaped piston cylinder 4 through the exhaust pipe 37, and the sliding distance of the first arc-shaped sealing plug 42 in the first arc-shaped piston cylinder 4 driving the first arc-shaped piston rod 41 is shorter, so that the distance of the support block 57 driving the third circular ring 5 rotating is smaller, so that the sliding distance of the six fixing blocks 51 is shorter, so that the fixing block 51 can fix and support the oxygen cylinder with smaller diameter, and the effect that the fixing block 51 does not contact the oxygen cylinder to avoid the shaking of the oxygen cylinder is avoided.

[0042] Thus, the sliding distance of the fixing block 51 is self-adaptively adjusted according to the size of the diameter of the oxygen cylinder, so that oxygen cylinders with various diameters can be fixed, time and labor are saved, and different fixing mechanisms are not needed.

[0043] When the oxygen cylinder needs to be taken out, the circular table 45 is manually pushed by hand, so that the gas in the first arc-shaped piston cylinder 4 is exhausted, the elastic force of the second spring 43 is released, so that the first arc-shaped piston rod 41 drives the third circular ring 5 to reset, so that the fixing block 51 cancels the support of the oxygen cylinder.

[0044] The first support frame 1 is fixedly connected with the reinforcing rib 11.

[0045] The reinforcing rib is provided to strengthen the strength of the first support frame 1.

[0046] Embodiment two

[0047] The same as embodiment one, and further, the first support frame 1 is provided with a walking mechanism for convenient transportation, the walking mechanism comprising a support rod 14 fixedly connected to the first support frame 1, two rotating frames 6 rotatably connected to the support rod 14, three first rotating rods 61 rotatably connected to each rotating frame 6, and moving wheels 62 fixedly connected to each first rotating rod 61.

[0048] When walking on a bumpy road, the rotating frame 6 can rotate, so as to avoid the shaking of the oxygen cylinder, and the walking mechanism can also adapt to the situation of going upstairs, the rotating frame 6 contacts the step and then rotates, and the moving wheels 62 rotate synchronously, so as to save the labor and avoid the shaking of the oxygen cylinder when going upstairs.

[0049] The walking mechanism is provided to adapt to most roads, so as to ensure the safety of the oxygen cylinder during transportation, reduce the pushing force of the staff, and avoid the shaking of the oxygen cylinder in complex road conditions, so as to avoid the damage of the oxygen cylinder.

[0050] Embodiment three

[0051] The further support mechanism is provided with a second support plate 73 fixedly connected with the support rod 14, a second arc-shaped piston cylinder 7 fixedly connected with the second support plate 73, a second arc-shaped sealing plug 76 slidably connected with the second arc-shaped piston cylinder 7, a second arc-shaped piston rod 71 fixedly connected with the second arc-shaped sealing plug 76, a foot pedal 72 fixedly connected with the second arc-shaped piston rod 71 and rotatably connected with the support rod 14, and a third spring 77 placed in the second arc-shaped piston cylinder 7 and fixedly connected with the second arc-shaped sealing plug 76 and the second arc-shaped piston cylinder 7.

[0052] The further support mechanism is provided with a second support plate 73 fixedly connected with the support rod 14, a second arc-shaped piston cylinder 7 fixedly connected with the second support plate 73, a second arc-shaped sealing plug 76 slidably connected with the second arc-shaped piston cylinder 7, a second arc-shaped piston rod 71 fixedly connected with the second arc-shaped sealing plug 76, a foot pedal 72 fixedly connected with the second arc-shaped piston rod 71 and rotatably connected with the support rod 14, and a third spring 77 placed in the second arc-shaped piston cylinder 7 and fixedly connected with the second arc-shaped sealing plug 76 and the second arc-shaped piston cylinder 7.

[0053] The further support mechanism is provided with a second support plate 73 fixedly connected with the support rod 14, a second arc-shaped piston cylinder 7 fixedly connected with the second support plate 73, a second arc-shaped sealing plug 76 slidably connected with the second arc-shaped piston cylinder 7, a second arc-shaped piston rod 71 fixedly connected with the second arc-shaped sealing plug 76, a foot pedal 72 fixedly connected with the second arc-shaped piston rod 71 and rotatably connected with the support rod 14, and a third spring 77 placed in the second arc-shaped piston cylinder 7 and fixedly connected with the second arc-shaped sealing plug 76 and the second arc-shaped piston cylinder 7.

[0054] When the oxygen cylinder needs to change the support angle, the foot pedal 72 is manually stepped on intermittently, so that the second arc-shaped piston rod 71 and the second arc-shaped sealing plug 76 reciprocate in the second arc-shaped piston cylinder 7, and the pressure in the second arc-shaped piston cylinder 7 changes.

[0055] When the second arc-shaped piston rod 71 and the second arc-shaped sealing plug 76 slide in the second arc-shaped piston cylinder 7 away from the liquid inlet pipe 78, a negative pressure is generated under the cooperation of the second one-way valve 75, so that the hydraulic oil of the external hydraulic oil supply mechanism is sucked into the second arc-shaped piston cylinder 7 through the liquid inlet pipe 78; when the second arc-shaped piston rod 71 and the second arc-shaped sealing plug 76 slide in the second arc-shaped piston cylinder 7 towards the liquid inlet pipe 78, a high pressure is generated under the cooperation of the second one-way valve 75, so that the gas in the second arc-shaped piston cylinder 7 is sent into the oil cylinder 8 through the liquid outlet pipe 74, the oil cylinder 8 drives the first support plate 21 to rotate around the second rotating rod 12, until the first support plate 21 is rotated to a proper angle, and the foot pedal 72 is manually released.

[0056] The second one-way valve 75 is a controllable one-way valve.

[0057] When the oxygen cylinder needs to be reset, manually touch the switch to make the second one-way valve 75 switch the flow direction, and the elastic force of the torsion spring 13 is released, so that the hydraulic oil in the oil cylinder 8 flows away from the oil cylinder 8, thereby achieving the effect of resetting the oxygen cylinder.

[0058] Working principle: when using the oxygen cylinder transportation and support device, place the oxygen cylinder at the first circular ring 3, then the oxygen cylinder and the four wedge blocks 32, and make the four wedge blocks 32 slide away, then the oxygen cylinder continues to slide down along the second circular ring 52 and the third circular ring 5, and then contacts the first support plate 21.

[0059] When the four wedge blocks 32 slide away, the piston rod 33 on them drives the sealing plug 34 to slide towards the end close to the air inlet pipe 36, so that the gas in the first arc-shaped piston cylinder 4 is discharged through the exhaust pipe 37 into the first arc-shaped piston cylinder 4, thereby driving the first arc-shaped second arc-shaped piston rod 71 in the first arc-shaped piston cylinder 4 to slide away from the end of the exhaust pipe 37, so that the support block 57 drives the third circular ring 5 to rotate along the rotating groove on the second support frame 2. Since the sliding block 54 on the fixed block 51 is slidingly connected to the first hexagonal groove 56 on the second circular ring 52, and the inclined sliding groove 55 on the third circular ring 5 is slidingly connected to the sliding rod 53 on the fixed block 51, the six fixed blocks 51 slide, thereby fixing and supporting the oxygen cylinder, as shown in Figure 6 The sealing state of the six fixed blocks 51.

[0060] And because of the diameter of the oxygen cylinder, the sliding stroke of the wedge block 32 and the piston rod 33 is different.

[0061] When the diameter of the oxygen cylinder is larger, the sliding stroke of the wedge block 32 and the piston rod 33 is longer, so that more gas in the piston cylinder 31 is transported into the first arc-shaped piston cylinder 4 through the exhaust pipe 37, thereby the first arc-shaped sealing plug 42 in the first arc-shaped piston cylinder 4 drives the first arc-shaped piston rod 41 to slide a longer distance, so that the support block 57 drives the third circular ring 5 to rotate a longer distance, thereby the six fixed blocks 51 slide a longer distance, thereby the fixed blocks 51 fix and support the oxygen cylinder with larger diameter, and avoid the interference between the oxygen cylinder and the fixed blocks 51.

[0062] When the diameter of the oxygen cylinder is small, the sliding stroke of the wedge 32 driving the piston rod 33 is short, so that the gas in the piston cylinder 31 is delivered to the first arc-shaped piston cylinder 4 through the exhaust pipe 37, and the sliding distance of the first arc-shaped sealing plug 42 in the first arc-shaped piston cylinder 4 is short, so that the sliding distance of the third circular ring 5 driven by the supporting block 57 is small, so that the sliding distance of the six fixing blocks 51 is short, so that the fixing block 51 supports the oxygen cylinder with small diameter, and avoids the effect that the fixing block 51 does not contact with the oxygen cylinder and the oxygen cylinder shakes.

[0063] Thus, the sliding distance of the fixing block 51 is adaptively adjusted according to the size of the diameter of the oxygen cylinder, so that oxygen cylinders of various diameters can be fixed, time and labor are saved, and different fixing mechanisms are not needed.

[0064] When the oxygen cylinder needs to be taken out, the circular table 45 is manually pushed, so that the gas in the first arc-shaped piston cylinder 4 is exhausted, the elastic force of the second spring 43 is released, so that the first arc-shaped piston rod 41 drives the third circular ring 5 to reset, so that the fixing block 51 cancels the support of the oxygen cylinder.

[0065] The circular table 45 can be provided with a spring, the other end of the spring is connected with the first arc-shaped piston cylinder 4, and other reset mechanisms can also be selected.

[0066] When walking on a bumpy road, the rotating frame 6 can rotate, so as to avoid the shaking of the oxygen cylinder, and the walking mechanism can also be adapted to the situation of climbing stairs, the rotating frame 6 contacts with the step and then rotates, and the moving wheel 62 rotates synchronously, so as to save the labor of climbing stairs and avoid the shaking effect.

[0067] By setting the walking mechanism, most roads can be adapted, so as to ensure the safety of the oxygen cylinder during transportation, reduce the pushing force of the staff, and avoid the shaking of the oxygen cylinder in complex road conditions, so as to avoid the damage of the oxygen cylinder.

[0068] When the oxygen cylinder needs to change the support angle, the foot pedal 72 is stepped by hand, and needs to be stepped intermittently, so that the second arc-shaped piston rod 71 and the second arc-shaped sealing plug 76 reciprocate in the second arc-shaped piston cylinder 7, so that the pressure in the second arc-shaped piston cylinder 7 changes, which will be described in detail as follows:

[0069] In the above, when the second arc-shaped piston rod 71 and the second arc-shaped sealing plug 76 slide in the second arc-shaped piston cylinder 7 in the direction away from the liquid inlet pipe 78, under the cooperation of the second one-way valve 75, negative pressure is generated, so that hydraulic oil from an external hydraulic oil supply mechanism is sucked into the second arc-shaped piston cylinder 7 through the liquid inlet pipe 78; when the second arc-shaped piston rod 71 and the second arc-shaped sealing plug 76 slide in the second arc-shaped piston cylinder 7 in the direction of the liquid inlet pipe 78, under the cooperation of the second one-way valve 75, high pressure is generated, so that the gas in the second arc-shaped piston cylinder 7 is sent into the oil cylinder 8 through the liquid outlet pipe 74, so that the oil cylinder 8 drives the first support plate 21 to rotate around the second rotating rod 12 until the second rotating rod 12 is rotated to a suitable angle, and then the foot pedal 72 is manually cancelled.

[0070] The second one-way valve 75 is a controllable one-way valve.

[0071] When the oxygen cylinder needs to be reset, the switch is manually touched, so that the second one-way valve 75 changes the flow direction, and the elastic force of the torsion spring 13 is released, so that the hydraulic oil in the oil cylinder 8 flows away from the oil cylinder 8, thereby achieving the effect of resetting the oxygen cylinder.

[0072] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
