Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder anti-dumping, and specifically discloses a gas cylinder anti-dumping device. Background Art

[0002] Steel gas cylinders are a type of mobile, refillable pressure vessel, and are special pressure vessels. They are widely used to store various gases, including industrial gases, medical gases, and firefighting gases. Since the substances stored in steel gas cylinders are often under high pressure, when the gas cylinders are tipped over, heated, or subjected to improper operation, they may cause explosions and other dangers.

[0003] During the equipment manufacturing process, it is usually necessary to use steel gas cylinders in fixed places for production operations. In the traditional operation process, steel gas cylinders are usually placed directly in the corner, or simply tied with wire, hemp rope, etc., and the compressed gas is directly released for production operations. In order to improve safety and prevent gas cylinders from tipping over, the patent with announcement number CN215446032U discloses a gas cylinder anti-tipping mechanism, including two inclined support rods, a vertical rod is provided in the middle position of the support rod, a roller is provided at the lower end of the vertical rod, a support frame is provided at the bottom of the support rod, and a pallet for carrying the gas cylinder is provided between the two support rods. The gas cylinder can be placed on the pallet, and the bottom of the gas cylinder is supported on the support frame. The gas cylinder is firmly positioned and will not tip over.

[0004] However, in the above solution, the support rod is fixedly connected to the vertical rod, which causes the entire gas cylinder anti-dumping mechanism to be large in size and difficult to place. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a gas cylinder anti-dumping device to solve the problem that the support rod and the vertical rod are fixedly connected, resulting in the entire gas cylinder anti-dumping mechanism being large in size and difficult to place.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A gas cylinder anti-dumping device comprises two main rods, the lower ends of the two main rods are fixedly provided with support plates, a support plate is provided between the two main rods, and a support rod is hingedly connected to the upper end of each main rod; a connecting rod is provided in the middle of the support rod; a limiting assembly is provided on the outer side of the middle of the main rod; the limiting assembly can limit the angle between the support rod and the main rod. The support rod hingedly provided on the main rod reduces the volume when folded, and is convenient for folding and folding. The setting of the limiting assembly ensures the stability of the entire gas cylinder anti-dumping device when the support rod is lowered to prevent tipping.

[0008] Preferably, the cross section of the main rod is concave-shaped, so as to further reduce the volume of the supporting rod when it is folded.

[0009] Preferably, a clearance groove 1 is provided in the middle of the inner side wall of the main rod in cooperation with the connecting rod, so as to further reduce the volume of the support rod when it is folded, and facilitate the support rod to be placed entirely in the main rod when it is folded.

[0010] Preferably, the limiting assembly includes a straight rod; one end of the straight rod is hinged on the outer wall of the middle part of the main rod; a long hole is arranged on the straight rod; a hinge shaft is fixedly arranged on the outer wall of the middle part of the support rod; the hinge shaft is arranged in the long hole. The long hole can be used to limit the angle between the support rod and the main rod to prevent the entire gas cylinder anti-dumping device from tipping over when the angle is too large.

[0011] Preferably, a second clearance groove is provided on the outer side wall of the main rod to cooperate with the hinge shaft. When the support rod is retracted in the main rod, it is ensured that the limiting assembly does not interfere.

[0012] Preferably, an external thread is provided on the outer wall of the hinge shaft, and a nut is provided on the external thread, so as to limit the movement of the straight rod along the axial direction of the hinge shaft, ensure the normal operation of the limit assembly, and ensure the structural stability of the gas cylinder anti-dumping device.

[0013] Preferably, the limiting assembly includes a limiting rod; one end of the limiting rod is hinged on the outer wall of the middle part of the main rod; and a stopper rod is fixedly arranged inside the other end of the limiting rod. The stopper rod can be used to limit the angle between the support rod and the main rod to prevent the entire gas cylinder anti-dumping device from tipping over when the angle is too large.

[0014] The utility model has the following beneficial effects: the support rod hingedly arranged on the main rod reduces the volume when folded, and is convenient for folding and folding. The setting of the limit assembly ensures the stability of the entire gas cylinder anti-dumping device when the support rod is lowered to prevent dumping. BRIEF DESCRIPTION OF THE DRAWINGS
