[0002] A cylinder is a steel cylinder for storing high-pressure oxygen, gas, liquefied petroleum gas, etc. Gas cylinders generally contain permanent gases, liquefied gases or mixed gases.

[0003] When operating on the inside of a cylinder, it is necessary to first open the cylinder cap at its end. Since the cylinder cap can ensure the airtightness inside the cylinder, the connection between the cylinder cap and the cylinder is very tight. Most traditional opening methods require two people to cooperate. One person holds the cylinder to fix it, and the other person holds a tool to remove the cylinder cap. The whole process is not only time-consuming and laborious, but also there are certain safety hazards in manually fixing the cylinder. Therefore, there is an urgent need for an adjustable cylinder clamping device to solve the above problems. Content of the Utility Model

[0004] Based on the deficiencies in the prior art mentioned in the above background technique, the utility model provides an adjustable cylinder clamping device.

[0005] The utility model overcomes the above technical problems by adopting the following technical solutions, specifically:

[0006] An adjustable cylinder clamping device includes a clamping seat. The cross-section of the clamping seat is concave. One inner wall of the clamping seat is rotatably connected with a threaded lead screw. A threaded sleeve is meshed with the circumferential outer wall of the threaded lead screw. A reinforcing column is fixedly connected to the top outer wall of the threaded sleeve. The top end of the reinforcing column is fixedly connected to a guiding cylinder. Both inner walls of the clamping seat are fixedly connected with guiding rods. The guiding cylinder is sleeved on the circumferential outer wall of the guiding rod. A bent rod is fixedly connected to the top outer wall of the guiding cylinder. One end of the bent rod away from the guiding cylinder passes through one side of the clamping seat. A positioning shell is fixedly connected to one end of the bent rod. A positioning roller for clamping the cylinder body is arranged on one side of the positioning shell;

[0007] An adjusting assembly is arranged inside the positioning shell.

[0008] As a further scheme of the utility model: One end of the threaded lead screw is fixedly connected with an end column. A threaded hole is opened inside the end column. A handle is threadedly connected inside the threaded hole.

[0009] As a still further scheme of the utility model: Both inner walls of the positioning shell are rotatably connected with rotating columns. A rotating plate is fixedly connected to the circumferential outer wall of the rotating column. One end of a rotating shaft is rotatably connected to the outer wall of one side of the rotating plate. One end of the rotating shaft is fixedly connected with the positioning roller.

[0010] As a further solution of the present utility model: the number of the positioning rollers on one side of a group of the positioning shells is two groups, and the two groups of the positioning rollers are distributed up and down.

[0011] As a further solution of the present utility model: the adjusting assembly includes a gear fixedly connected to the circumferential outer wall of the rotating column, the gear meshes with a toothed plate, and the bottom of the toothed plate meshes with another gear.

[0012] As a further solution of the present utility model: a vertical plate is fixedly connected to the outer wall of one side of the toothed plate, a bearing seat is fixedly connected to the outer wall of one side of the vertical plate, a threaded rod is fixedly connected to the inner wall of the circumferential of the bearing seat, and a turning handle is fixedly connected to the end of the threaded rod away from the bearing seat.

[0013] As a further solution of the present utility model: a threaded tube is fixedly connected to the outer wall of one side of the positioning shell, and the threaded rod meshes with the threaded tube.

[0014] As a further solution of the present utility model: a guide plate is fixedly connected to the inner wall of one side of the positioning shell, the number of the guide plates is two groups, and the outer walls of one sides of the two groups of the guide plates are both in contact with the outer wall of one side of the toothed plate.

[0015] After adopting the above structure, compared with the prior art, the present utility model has the following advantages:

[0016] 1. In the present utility model, by arranging a threaded screw rod, a handle and positioning rollers, when it is necessary to fix the cylinder body, the staff can rotate the handle, and the end post and the threaded screw rod can be driven to rotate together by the handle. Since the threaded screw rod is a bidirectional screw rod, during the rotation of the threaded screw rod, two threaded sleeves meshing on its outer wall can move towards each other, and during the movement of the threaded sleeves towards each other, the positioning rollers can move towards the middle of the clamping seat, so as to effectively clamp the cylinder body, and the fixation of the cylinder can be realized without the cooperation of multiple people, which is convenient for the staff to perform operations inside the cylinder body subsequently.

The turning handle can drive the threaded rod to rotate. At the same time, one end of the threaded rod is rotatably connected to the vertical plate, and the vertical plate is firmly fixed to the toothed plate. Therefore, during the rotation of the threaded rod, the toothed plate can be driven to move horizontally. When the toothed plate moves horizontally, it will mesh with the gears on the upper and lower sides, so as to adjust the opening degree between the two groups of positioning rollers through the rotation of the gears, so that the positioning rollers can clamp and fix cylinders of different specifications, and the applicable range of the device is expanded.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6, in the embodiment of the present utility model, an adjustable cylinder clamping device includes a clamping seat 1. The cross-section of the clamping seat 1 is concave. One inner wall of the clamping seat 1 is rotatably connected with a threaded lead screw 15. A threaded sleeve 16 is engaged with the circumferential outer wall of the threaded lead screw 15. A reinforcing column is fixedly connected to the top outer wall of the threaded sleeve 16. The top end of the reinforcing column is fixedly connected to a guide cylinder 18. Guide rods 17 are fixedly connected to both inner walls of the clamping seat 1. The guide cylinder 18 is sleeved on the circumferential outer wall of the guide rod 17. A bent rod 19 is fixedly connected to the top outer wall of the guide cylinder 18. One end of the bent rod 19 away from the guide cylinder 18 passes through one side of the clamping seat 1. A positioning shell 7 is fixedly connected to one end of the bent rod 19. A positioning roller 3 for clamping the cylinder body 10 is arranged on one side of the positioning shell 7. An adjusting component is arranged inside the positioning shell 7. One end of the threaded lead screw 15 is fixedly connected to an end column 11. A threaded hole is opened inside the end column 11. A handle 12 is threadedly connected to the inside of the threaded hole. When it is necessary to fix the cylinder body 10, the staff can rotate the handle 12. By rotating the handle 12, the end column 11 and the threaded lead screw 15 can be driven to rotate together. Since the threaded lead screw 15 is a bidirectional lead screw, during the rotation of the threaded lead screw 15, the two threaded sleeves 16 engaged on its outer wall can move towards each other. During the movement of the threaded sleeves 16 towards each other, the positioning roller 3 can move towards the middle of the clamping seat 1, so as to effectively clamp the cylinder body 10. It is possible to fix the cylinder without the cooperation of multiple people, which facilitates the subsequent operation of the staff inside the cylinder body 10.

[0027] Preferably, rotating columns 6 are rotatably connected to both inner walls of the positioning shell 7. A rotating plate 4 is fixedly connected to the circumferential outer wall of the rotating column 6. A rotating shaft is rotatably connected to one outer wall of the rotating plate 4. One end of the rotating shaft is fixedly connected to the positioning roller 3.

[0028] Preferably, the number of the positioning rollers 3 on one side of a group of positioning shells 7 is two. The two positioning rollers 3 are distributed vertically. By distributing four positioning rollers 3 on both sides of the cylinder body 10, the fixing effect on the cylinder body 10 can be further improved.

[0029] Preferably, the adjusting assembly includes a gear 5 fixedly connected to the circumferential outer wall of the rotating column 6. The gear 5 meshes with a rack 8. The bottom of the rack 8 meshes with another gear 5. One side outer wall of the rack 8 is fixedly connected to a vertical plate. One side outer wall of the vertical plate is fixedly connected to a bearing seat 21. The inner circumferential wall of the bearing seat 21 is fixedly connected to a threaded rod 13. One end of the threaded rod 13 away from the bearing seat 21 is fixedly connected to a turning handle 9. By turning the turning handle 9, the threaded rod 13 can be driven to rotate. At the same time, one end of the threaded rod 13 is rotatably connected to the vertical plate, and the vertical plate is firmly fixed to the rack 8. Therefore, when the threaded rod 13 rotates, the rack 8 can be driven to move horizontally. When the rack 8 moves horizontally, it will mesh with the upper and lower gears 5, so as to adjust the opening degree between the two positioning rollers 3 through the rotation of the gears 5, enabling the positioning rollers 3 to clamp and fix gas cylinders of different specifications, expanding the applicable range of the device. One side outer wall of the positioning shell 7 is fixedly connected to a threaded tube 14. The threaded rod 13 meshes with the threaded tube 14. The rotation of the threaded rod 13 can be locked through the threaded tube 14, ensuring that the positioning rollers 3 mentioned above remain stable after adjusting the angle.

[0030] Preferably, two guide plates 20 are fixedly connected to one side inner wall of the positioning shell 7. One side outer walls of the two guide plates 20 are in contact with one side outer wall of the rack 8. The guide plates 20 can play a good guiding role in the movement of the rack 8, avoiding the situation of unstable movement of the rack 8.

[0031] Working principle: When it is necessary to fix the gas cylinder body 10, the staff can rotate the handle 12. By rotating the handle 12, the end column 11 and the threaded lead screw 15 can be driven to rotate together. Since the threaded lead screw 15 is a bidirectional lead screw, during the rotation of the threaded lead screw 15, the two threaded sleeves 16 meshing on its outer wall can move towards each other. During the movement of the threaded sleeves 16 towards each other, the positioning rollers 3 can be moved towards the middle of the clamping seat 1, so as to effectively clamp the gas cylinder body 10. Fixing the gas cylinder can be achieved without the cooperation of multiple people, facilitating the subsequent operation of the staff on the inside of the gas cylinder body 10. And before fixing the gas cylinder body 10 through the positioning rollers 3, the staff can rotate the turning handle 9 according to the specification of the gas cylinder body 10. By rotating the turning handle 9, the threaded rod 13 can be driven to rotate. At the same time, one end of the threaded rod 13 is rotatably connected to the vertical plate, and the vertical plate is firmly fixed to the rack 8. Therefore, when the threaded rod 13 rotates, the rack 8 can be driven to move horizontally. When the rack 8 moves horizontally, it will mesh with the upper and lower gears 5, so as to adjust the opening degree between the two positioning rollers 3 through the rotation of the gears 5, enabling the positioning rollers 3 to clamp and fix gas cylinders of different specifications, expanding the applicable range of the device.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
