Description

Technical Field

[0001] The utility model belongs to the technical field of gas filling steel cylinders, and in particular relates to a steel cylinder mouth protection device. Background Art

[0002] When transporting industrial gases, steel cylinders are required as storage media. Since there is a high pressure inside the steel cylinder and the mouth of the cylinder is relatively slender, the valve body at the mouth of the cylinder is easily damaged by collision, causing gas leakage, posing a safety hazard.

[0003] A Chinese patent with publication number CN214777885U discloses a cylinder mouth protection device, which includes: a protective shell and two sets of clamping mechanisms. The above scheme uses the threaded preload force to make the pressure block fit and press against the cylinder, and combines the elastic force of the clamping spring to fix the position of the pressure block, so that the cylinder mouth protection device has an anti-impact protection effect.

[0004] However, the main problems with the steel cylinder mouth protection device are: when operating the clamping mechanism to press the steel cylinder mouth, multiple rotating rods need to be rotated separately, resulting in low working efficiency. Utility Model Content

[0005] The utility model aims to provide a steel cylinder mouth protection device to solve the problem of low working efficiency when the existing steel cylinder mouth protection device clamps the steel cylinder mouth.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A steel cylinder mouth protection device comprises a ring mouth, an adjustment mechanism and a steel belt, wherein a first shell and a plurality of second shells are fixedly arranged at the bottom of the ring mouth, the first shell and the second shell are both elastic, the first shell and the second shell are arranged in a ring shape, gaps are left between the first shell and the second shell and between adjacent second shells, the first shell is provided with an inner cavity, the adjustment mechanism is inserted into the first shell, the steel belt is passed through the plurality of second shells, one end of the steel belt is fixedly connected to the right end side wall of the first shell, the other end passes through the left end side wall of the first shell and extends into the inner cavity, and the other end of the steel belt is slidably connected to the adjustment mechanism.

[0008] The principle and effect of this technical solution:

[0009] The steel cylinder mouth protection device is sleeved on the steel cylinder mouth, and the adjusting mechanism is rotated to shorten the length of the steel belt exposed from the first shell, so as to drive the first shell and multiple second shells to tighten inwards until the steel cylinder mouth is clamped.

[0010] Through the above arrangement, by rotating an adjustment mechanism, the first shell and multiple second shells are driven to tighten inward at the same time and clamp the mouth of the cylinder, thereby achieving the purpose of making the cylinder mouth protection device have an anti-fighting protection effect. At the same time, compared with the prior art, the number of adjustment mechanisms that need to be adjusted is reduced, thereby improving work efficiency.

[0011] In the utility model, the adjustment mechanism includes a rod handle, a screw and an adjustment block. The screw is inserted into the first shell and is threadedly connected to the first shell. One end of the screw extends into the inner cavity and is rotatably connected to the adjustment block. The other end of the screw is fixedly provided with a rod handle. The other end of the steel belt is fixedly provided with a limit block. The adjustment block and the limit block are both provided with inclined surfaces, and the inclined surface of the limit block abuts against the inclined surface of the adjustment block.

[0012] The principle and effect of this technical solution:

[0013] The handle is rotated to make one end of the screw push the adjusting block to move toward the steel belt. When the inclined surface of the adjusting block abuts against the inclined surface of the limiting block, the adjusting block continues to move toward the steel belt, and the limiting block is squeezed by the adjusting block and slides to the right.

[0014] Through the above arrangement, the adjusting block can drive the limiting block to move, thereby achieving the purpose of controlling the length of the steel belt exposed from the first shell.

[0015] In the utility model, a warning mechanism and an elastic film are also included, the warning mechanism includes a cross bar and a color strip, the elastic film is arranged in the gap and connected to the inner wall of the gap, and the elastic film is fixedly connected to the ring mouth, the cross bar is transversely arranged between the inner walls of the ring mouth, and the color strip is sleeved on the cross bar. Through the above arrangement, when the bottle mouth leaks, the gas can be guided to blow out from the middle of the ring mouth and blow up the color strip, which is convenient for staff to observe.

[0016] In the utility model, the surface of the color strip has a fluorescent layer. Through the above arrangement, the staff can observe whether there is gas leakage at the bottle mouth at night.

[0017] In the utility model, the inner walls of the first shell and the second shell are both provided with anti-skid pads. Through the above arrangement, the cylinder mouth protection device can be prevented from sliding off the bottle mouth, thereby improving the operating efficiency.

[0018] In the utility model, the first shell and the second shell are both arranged in an arc shape. Through the above arrangement, the contact area between the steel cylinder mouth protection device and the steel cylinder mouth can be increased, and the steel cylinder mouth can be prevented from being locally over-pressurized and thus damaged.

[0019] In the present invention, the number of the second shells is three. BRIEF DESCRIPTION OF THE DRAWINGS
