Description

Technical Field

[0001] This utility model relates to the field of gas cylinder technology, and in particular to a gas cylinder with a flexible full protective layer. Background Technology

[0002] Gas cylinders are containers used for storing and transporting compressed or liquefied gases, and are widely used in industry, medical fields, laboratories, and households. The design and manufacture of gas cylinders require very strict standards and must meet relevant safety standards to ensure safety and reliability when used in high-pressure environments.

[0003] Existing protective layers are typically simply fitted onto the gas cylinder, failing to completely cover it. This leaves the exposed parts of the cylinder vulnerable to impact damage, and the loose connections allow the protective layer to detach, affecting usability. Furthermore, existing protective layers on gas cylinders merely isolate the cylinder from the outside environment, offering limited functionality and inadequate protection. Therefore, those skilled in the art have developed a gas cylinder with a flexible, fully protective layer to address the problems described in the background section. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gas cylinder with a flexible full protective layer. The functional layer can greatly improve the protective performance of the protective layer, resulting in better usability. Furthermore, the limiting mechanism allows for convenient assembly, disassembly, and maintenance of the two protective covers, providing greater convenience.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gas cylinder with a flexible full protective layer includes an upper protective cover, a lower protective cover, and a gas cylinder body. The gas cylinder body is movably fitted inside the upper and lower protective covers. A limiting mechanism is provided between the upper and lower protective covers. Both the upper and lower protective covers include an inner protective layer. A functional layer is adhered and fitted onto the outer wall of the inner protective layer.

[0007] The limiting mechanism includes two mounting posts and two mounting ports. The two mounting posts are fixedly connected to both sides of the lower end face of the upper protective cover, and the two mounting ports are respectively opened on both sides of the upper end face of the lower protective cover. The mounting posts are engaged in the mounting ports. An adjustment groove is opened on one side of the mounting post. A return spring is fixedly connected to the inner wall of one side of the adjustment groove. A moving plate is fixedly connected to one end of the return spring. A locking rod is fixedly connected to the other side of the moving plate. A locking hole is opened on one side of the mounting port, and the locking rod is engaged in the locking hole.

[0008] With the above technical solution, the upper and lower protective covers are fitted onto the gas cylinder body. Pressing the locking rod causes the moving plate to be stressed and pushes the return spring to compress. The locking rod moves into the adjustment groove, and the mounting column is unrestricted and locked into the mounting opening. At this time, the return spring pops out, causing the moving plate to move synchronously. The locking rod is stressed and moves and locks into the locking hole. The upper and lower protective covers are stably fixed, and the gas cylinder body is sealed and protected, providing better usability. When it is necessary to remove the gas cylinder body for use, simply press the locking rod to remove the upper protective cover, providing greater convenience.

[0009] Furthermore, the functional layer includes a wear-resistant layer, a heat-resistant layer is adhered to the inner wall of the wear-resistant layer, a corrosion-resistant layer is adhered to the inner wall of the heat-resistant layer, and a buffer layer is adhered to the inner wall of the corrosion-resistant layer.

[0010] Through the above technical solution, the functional layers can achieve the function of high-strength use of the inner protective layer. The added wear-resistant layer can greatly improve the wear resistance of the inner protective layer, the added heat-resistant layer can effectively block the heat transfer brought by external heat, the added corrosion-resistant layer can prevent the gas cylinder from being corroded by external chemical substances, and the added buffer layer can improve excellent elasticity and impact resistance.

[0011] Furthermore, the wear-resistant layer is made of chromium alloy, and the heat-resistant layer is made of silicone.

[0012] The above technical solution achieves high strength and wear resistance through a wear-resistant layer made of chromium alloy, and achieves better heat resistance through a heat-resistant layer made of silicone.

[0013] Furthermore, the corrosion-resistant layer is made of stainless steel, and the buffer layer is made of foam.

[0014] The above technical solutions achieve better corrosion resistance through a corrosion-resistant layer made of stainless steel, and better protection for the gas cylinder body through a buffer layer made of foam.

[0015] Furthermore, the upper and lower end faces of the movable plate are fixedly connected to limit sliders, and the inner walls of the upper and lower ends of the adjustment groove are provided with limit grooves, and the limit sliders are slidably disposed in the limit grooves.

[0016] The above technical solution achieves the purpose of limiting the movement of the moving plate by sliding the limiting slider in the limiting groove.

[0017] Furthermore, a limiting plate is fixedly connected to the lower end face of the mounting column, and a limiting groove is formed on the lower inner wall of the mounting port, with the limiting plate engaging in the limiting groove.

[0018] The above technical solution achieves a better limiting effect by using the locking mechanism of the limiting plate within the limiting slot.

[0019] Furthermore, annular retaining plates are fixedly connected to the lower end face of the upper protective cover at both the front and rear, and annular slots are opened on the upper end face of the lower protective cover at both the front and rear, with the annular retaining plates engaging in the annular slots.

[0020] The above technical solution achieves a stable connection between the upper and lower protective covers by using the snap-fit ​​mechanism of the annular plate within the annular slot.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a gas cylinder with a flexible full protective layer. An upper and lower protective cover are fitted onto the gas cylinder body. Pressing the locking rod causes the moving plate to be stressed and pushes the return spring to compress. The locking rod moves into the adjustment groove, and the mounting post is unrestricted and locked into the mounting opening. At this time, the return spring pops out, causing the moving plate to move synchronously. The locking rod is stressed and moves, locking into the locking hole. The upper and lower protective covers are stably fixed, and the gas cylinder body is sealed and protected, providing better usability. When the gas cylinder body needs to be removed for use, simply pressing the locking rod removes the upper protective cover, providing greater convenience.

[0023] 2. The gas cylinder with a flexible full protective layer proposed in this utility model can achieve high-strength use of the inner protective layer through the setting of functional layers. The added wear-resistant layer can greatly improve the wear resistance of the inner protective layer, the added heat-resistant layer can effectively block the heat transfer from the outside, the added corrosion-resistant layer can prevent the gas cylinder from being corroded by external chemicals, and the added buffer layer can improve the excellent elasticity and impact resistance, thereby achieving better protection for the main body of the gas cylinder.
