Description

Technical Field

[0001] This utility model relates to the field of enamel label hanging technology, and in particular to a folding hook for enamel gas cylinder labels. Background Technology

[0002] In the field of industrial gas storage and transportation, enamel gas cylinders are widely used due to their corrosion resistance and high strength. In order to clearly identify key information such as the medium, pressure, filling date and safety warnings inside the cylinder, it is usually necessary to hang an enamel label in a prominent position on the cylinder body.

[0003] Currently, traditional label hanging methods have the following drawbacks: When multiple labels (such as medium identification, inspection labels, filling records, etc.) need to be hung on gas cylinders at the same time, multiple independent hooks or slots usually need to be installed on the cylinder body or bracket. This not only requires multiple rows of fixing points to be arranged on the limited cylinder surface, resulting in low space utilization, but also increases the complexity of installation and maintenance. Moreover, most existing hooks are rigid structures that cannot be folded and stored, resulting in a large space occupation when idle or transported. Furthermore, the protruding hook parts are easy to snag on foreign objects, making them inconvenient to use.

[0004] To address this issue, we propose a folding hook for enamel gas cylinder labels. Utility Model Content

[0012] In a further embodiment, the hook consists of a straight rod and a bent hook, with the top end of the straight rod fixedly connected to a telescopic joint and the bottom end of the straight rod rotatably connected to the bent hook.

[0013] In a further embodiment, a pair of rubber rings are also fitted over the hook portion of the hook, with the pair of rubber rings located on both sides of the enamel label.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model uses a telescopic hanging rod composed of multi-stage telescopic joints, which can hang multiple enamel labels at the same time, eliminating the need for multiple rows of independent hooks.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A folding hook for enamel gas cylinder labels includes a base 1, a screw 2 threaded through and connected to the base 1, and a pressure plate 3 installed at one end of the screw 2 extending into the base 1. Specifically, the pressure plate 3 and the screw 2 are rotatably connected, and anti-slip pads 9 are connected to the bottom surface of the pressure plate 3 and the inner bottom surface of the base 1 to reduce slippage. A telescopic hanging rod is rotatably connected to the outside of the base 1. Specifically, a rotating sleeve 7 is fixed at one end of the telescopic hanging rod near the base 1, and a fixed rod 8 passes through the rotating sleeve 7. The fixed rod 8 is fixed in a groove 12 of the base 1. The telescopic hanging rod is composed of several telescopic sections 4 that slide and fit together in sequence. The telescopic sections 4 gradually taper from the direction near the base 1 to the direction away from the base 1. Specifically, the tail end of the telescopic section 4 is provided with a protruding ring 4 protruding from the outer circumference. 1. The head end of the telescopic joint 4 is provided with a protruding edge 42 protruding from the inner circumferential surface. When the thinner telescopic joint 4 moves within the thicker telescopic joint 4, the protruding ring 41 of the thinner telescopic joint 4 will be stopped and limited by the protruding edge 42 of the thicker telescopic joint 4, so that the adjacent telescopic joints 4 will not separate. A hook 5 is installed below the head end of each telescopic joint 4, and an enamel label 10 is suspended on the hook 5. The hook 5 is composed of a straight rod part 51 and a bent hook part 52. The top end of the straight rod part 51 is fixedly connected to the telescopic joint 4, and the bottom end of the straight rod part 51 is rotatably connected to the bent hook part 52. A pair of rubber rings 11 are also sleeved on the outside of the bent hook part 52 of the hook 5. The pair of rubber rings 11 are located on both sides of the enamel label 10. An end block 6 is also installed at the head end of the telescopic joint 4 furthest from the base 1.

[0025] Working principle: When in use, place the base 1 on the protective ring of the gas cylinder, rotate the screw 2 to drive the pressure plate 3 to move down, and clamp the protective ring through the anti-slip pads 9 on both sides. The pressure plate 3 and the screw 2 are connected by a bearing to ensure that the pressure plate 3 does not rotate with the screw 2 when tightened, so as to avoid the label shifting. Then, hold the end block 6 and pull it outward. The telescopic joints 4 extend step by step. Due to the locking of the convex ring 41 by the convex edge 42, the telescopic hanging rod rotates around the fixed rod 8 through the rotating sleeve 7 until it is perpendicular to the base 1. When not in use, rotate it to fit against the base 1. Then, put the enamel label 10 into the hook part 52 of the hook 5. The hook part 52 can rotate around the straight rod part 51 to adjust the label orientation. The rubber ring 11 is symmetrically fitted on the outer wall of the hook part 52 to elastically press the label on both sides to prevent slippage.
