Description

Technical Field

[0001] This utility model relates to the field of cylinder handle technology, and in particular to a handle assembly and a gas cylinder including the handle assembly. Background Technology

[0002] Gas cylinders are pressure vessels used for storing and transporting high-pressure oxygen, coal gas, liquefied petroleum gas, and other gases. Gas cylinders possess pressure-bearing characteristics and good sealing performance. As an important gas container, they are safety equipment for carrying compressed gases, liquefied gases, or other flammable or hazardous gases, and are widely used in various fields such as production, scientific research, medical treatment, and engineering construction. To facilitate the handling and movement of cylinders, they are usually equipped with handles on the top for easy lifting, making it more convenient and effortless to lift the cylinder. The handle design also protects the cylinder valve.

[0003] Currently, most cylinder handles are fixed to the top of the cylinder by welding. This welding method is not only time-consuming and labor-intensive, resulting in low efficiency, but also makes the cylinder handles, which are typically thin-walled structures, susceptible to deformation due to localized heating during welding. Improper welding sequence or lack of rigid fixing measures can lead to significant welding deformation, affecting the handle's accuracy and appearance. Furthermore, post-weld deformation is difficult to correct, and the process is costly and challenging. In addition, the complex structure and confined space of the handle make it difficult to ensure sufficient penetration depth and weld uniformity during welding. Improper operation can easily result in welding defects such as incomplete fusion, slag inclusions, or porosity, leading to connection defects or reducing the overall structural strength of the cylinder. While some cylinder handle structures are now installed using clamping methods, allowing for easy installation and removal, these still have the following drawbacks in practical use: (1) The assembly operation is complicated and inconvenient, and the assembly is not firm. The handle is easy to fall off during the handling and movement of the cylinder, which will cause the cylinder to fall and break, and there is a great safety hazard. (2) The handle is easy to rotate. During use, the handle may easily block the valve outlet of the gas cylinder due to rotation, affecting the use of the gas cylinder. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art as mentioned above, in-depth research was conducted, and after a great deal of creative work, this utility model was completed.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a handle assembly and a gas cylinder including the handle assembly, so as to solve the technical problems of the current gas cylinder handle, which has the problems of cumbersome and inconvenient assembly operation, easy to fall off and easy to rotate.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A handle assembly includes a clamping ring and a lifting handle. The clamping ring is a detachable split structure and has a clamping hole adapted to the top opening of a steel cylinder. The clamping hole is gradually narrowed from top to bottom, and the inner wall of the clamping hole is provided with several anti-slip protrusions. The lifting handle includes an integrally formed pressing part, a connecting part, and a gripping part. The pressing part has a clearance hole for avoiding the top of the cylinder opening, and the pressing part has an anti-disengagement edge that matches the outer diameter of the clamping ring. The connecting part is located between the pressing part and the gripping part.

[0007] As an improved technical solution, the clamping ring has at least one limiting protrusion, and the pressing part has a limiting groove that matches the limiting protrusion.

[0008] As an improved technical solution, the clamping ring includes a first clamping member and a second clamping member. Both the first clamping member and the second clamping member include an integrally formed crimping part, a clamping part, and a connecting ear. The clamping part and the connecting ear are both located on one side of the crimping part. The clamping part has an arched structure, and the clamping part and the crimping part have an arc-shaped groove. The groove surface of the arc-shaped groove is provided with a plurality of anti-slip protrusions. The connecting ear is located at both ends of the clamping part. When the first clamping member and the second clamping member are in a connected state, the two arc-shaped grooves surround and form the clamping hole.

[0009] As an improved technical solution, each of the connecting ears is provided with a connecting hole, and a connecting nut is fixedly installed in the connecting hole of the first clamping member or the second clamping member.

[0010] As an improved technical solution, the first clamping member and / or the second clamping member are provided with the limiting protrusion, which is located on the outer wall of the pressing part of the first clamping member and / or the second clamping member.

[0011] As an improved technical solution, a hand avoidance opening is formed between the pressing part, the connecting part and the gripping part to facilitate hand insertion and gripping, and the lifting handle also has a valve avoidance opening corresponding to the hand avoidance opening.

[0012] As an improved technical solution, the end of the pressing part away from the gripping part has an abutment edge that is adapted to the outer wall of the top of the cylinder.

[0013] As an improved technical solution, the pressing part has an assembly groove for positioning the clamping ring. The assembly groove is coaxially arranged with the clearance hole, and the depth of the assembly groove is consistent with the thickness of the pressing part of the clamping ring.

[0014] This utility model also discloses a gas cylinder, including the handle assembly described above, and a cylinder body. The top of the cylinder body has a bottle mouth, a bottle valve is installed at the bottle mouth, and the outer diameter of the bottle mouth gradually widens from bottom to top and is adapted to the clamping hole. The lifting handle is located at the top of the cylinder body, the cylinder mouth extends into the clearance hole, the clamping ring is fixedly installed on the cylinder mouth by connecting bolts, and the pressing part is located between the clamping ring and the cylinder body.

[0015] As an improved technical solution, the end of the pressing part away from the gripping part abuts against the top outer wall of the cylinder body via an abutment edge, and the gas outlet of the cylinder valve corresponds to the valve clearance port of the lifting handle.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are: (1) The handle assembly has a simple structure. When using it, first place the handle on the top of the cylinder body so that the cylinder mouth extends into the clearance hole of the handle. Then, fix the clamping ring on the cylinder mouth. The installation operation is simple, convenient, efficient and quick. After the handle assembly is installed, the pressing part of the handle is located between the clamping ring and the cylinder body. Since the clamping hole of the clamping ring is adapted to the cylinder mouth and gradually narrows from top to bottom, the clamping ring is not easy to fall off after installation. In addition, the anti-slip protrusions on the inner wall of the clamping hole increase the contact friction between the clamping ring and the cylinder mouth, further improving the installation firmness of the clamping ring and making it less likely to fall off. Thus, the clamping ring makes the handle installation firm and reliable. During the process of moving the cylinder by pulling the handle, the handle will not fall off, thus making the movement of the cylinder safe, reliable and convenient.

[0017] (2) The clamping ring has a limiting protrusion and the pressing part has a limiting groove. After the handle assembly is installed on the cylinder body, the limiting protrusion is located in the limiting groove. Since the clamping ring and the cylinder body are firmly and reliably installed, the lifting handle is not easy to rotate after installation, ensuring that the valve clearance port of the lifting handle always corresponds to the gas outlet port of the cylinder valve, thereby avoiding the phenomenon that the lifting handle blocks the gas outlet port of the cylinder valve during use.

[0018] (3) The clamping ring includes a first clamping part and a second clamping part. When in use, ensure that the bottle mouth of the steel cylinder body is located between the clamping parts of the first clamping part and the second clamping part. Then, connect and fix the first clamping part and the second clamping part through the connecting ear. This will enable the clamping ring to be installed and fixed on the bottle mouth of the steel cylinder body. This makes the installation and removal of the clamping ring on the bottle mouth of the steel cylinder body simple and convenient. In addition, the clamping parts of the first clamping part and the second clamping part and the connecting ear are both located on one side of the crimping part, that is, the connecting ear is higher than the crimping part. This makes it easy to connect the connecting ear of the first clamping part and the second clamping part through the valve clearance port when installing the clamping ring.

[0019] (4) Connecting holes are provided on the connecting ears of the clamping ring, and connecting nuts are fixedly installed in the connecting holes of the first clamping member or the second clamping member. When installing the clamping ring, the connecting bolt is threaded through the connecting holes of the corresponding two connecting ears and connected to the connecting nut. By tightening the connecting bolt, the first clamping member and the second clamping member can be pulled closer and firmly connected together. In this way, the clamping ring is clamped at the mouth of the steel cylinder body, making the installation of the clamping ring simple, convenient and reliable.

[0020] (5) The handle has a hand clearance opening, which makes it easy for staff to grasp the handle and move the cylinder, making the movement of the cylinder convenient and labor-saving. The handle also has a valve clearance opening, which can avoid the outlet of the cylinder valve.

[0021] (6) The pressing part has an abutting edge, which allows the lifting handle to make close contact with the outer wall of the top of the cylinder, ensuring that the lifting handle is stable and reliable after assembly and is not easy to loosen or shake.

[0022] (7) The depth of the assembly groove is consistent with the thickness of the pressing part of the clamping ring, so that after the clamping ring is placed in the assembly groove, it is easy to lock and fix the clamping ring through the valve clearance port, and the handle assembly is aesthetically pleasing.

[0023] (8) The gas cylinder is easy to install and remove the handle assembly on the cylinder body. The handle assembly is firmly and reliably installed on the cylinder body, and is not easy to fall off or rotate. The handle assembly protects the cylinder valve without affecting the use of the cylinder. It is also easy to move the gas cylinder by the handle assembly, making the movement of the gas cylinder convenient, labor-saving, safe and reliable. Attached Figure Description

[0030] like Figures 1 to 11 As shown in the figure, this embodiment provides a handle assembly, including a clamping ring 1 and a lifting handle 2. The clamping ring 1 is a detachable split structure, and the clamping ring 1 has a clamping hole adapted to the top opening of the steel cylinder. The clamping hole is gradually narrowed from top to bottom, and the inner wall of the clamping hole is provided with several anti-slip protrusions 104. The lifting handle 2 includes an integrally formed pressing part 201, a connecting part 202 and a gripping part 203. The pressing part 201 has a clearance hole for avoiding the top opening of the steel cylinder, and the pressing part 201 has an anti-disengagement edge 2011 adapted to the outer diameter of the clamping ring 1. The connecting part 202 is located between the pressing part 201 and the gripping part 203. This handle assembly has a simple structure. When using it, first place the lifting handle 2 on the top of the cylinder body so that the cylinder mouth extends into the clearance hole of the lifting handle 2. Then, fix the clamping ring 1 on the cylinder mouth. The installation operation is simple, convenient, efficient and quick, and the installation is firm and reliable and not easy to fall off.

[0031] In one embodiment, such as Figures 1 to 4, Figure 10 , Figure 11 As shown, a hand-avoidance opening is formed between the pressing part 201, the connecting part 202, and the gripping part 203 to facilitate hand insertion and gripping. The lifting handle 2 also has a valve avoidance opening corresponding to the hand-avoidance opening. The hand-avoidance opening of the lifting handle 2 facilitates the handling of the cylinder by the operator gripping the gripping part 203, making the handling of the cylinder convenient and effortless. The valve avoidance opening of the lifting handle 2 allows for the avoidance of the cylinder valve's outlet.

[0032] In one embodiment, such as Figures 1 to 9 As shown, the clamping ring 1 has at least one limiting protrusion 105, and the pressing part 201 has a limiting groove 2012 that matches the limiting protrusion 105. With the limiting protrusion 105 and the limiting groove 2012 in the pressing part 201, after the handle assembly is installed on the cylinder body, the limiting protrusion 105 is located within the limiting groove 2012. Because the clamping ring 1 and the cylinder body are securely and reliably installed, the lifting handle 2 is not easily rotated after installation, ensuring that the valve clearance port of the lifting handle 2 always corresponds to the outlet port of the cylinder valve, thereby preventing the lifting handle 2 from blocking the outlet port of the cylinder valve during use.

[0033] In one embodiment, such as Figures 1 to 9 As shown, the clamping ring 1 includes a first clamping member 1a and a second clamping member 1b. Both the first clamping member 1a and the second clamping member 1b include an integrally formed crimping part 101, a clamping part 102, and a connecting ear 103. The clamping part 102 and the connecting ear 103 are both located on one side of the crimping part 101. The clamping part 102 has an arched structure, and the clamping part 102 and the crimping part 101 have an arc-shaped groove. The groove surface of the arc-shaped groove is provided with a plurality of anti-slip protrusions 104. The connecting ear 103 is located at both ends of the clamping part 102. When the first clamping member 1a and the second clamping member 1b are in the connected state, the two arc-shaped grooves surround and form a clamping hole. In use, ensure that the bottle opening of the cylinder body is located between the clamping portions 102 of the first clamping member 1a and the second clamping member 1b, and then connect and fix the first clamping member 1a and the second clamping member 1b through the connecting lug 103. This will allow the clamping ring 1 to be installed and fixed on the bottle opening of the cylinder body, making the installation and removal of the clamping ring 1 on the bottle opening of the cylinder body simple and convenient. In addition, the clamping portions 102 of the first clamping member 1a and the second clamping member 1b and the connecting lug 103 are both located on one side of the crimping portion 101, that is, the connecting lug 103 is higher than the crimping portion 101. In this way, when installing the clamping ring 1, it is convenient to connect the connecting lug 103 of the first clamping member 1a and the second clamping member 1b through the valve clearance port.

[0034] In one embodiment, such as Figures 1 to 9As shown, each connecting lug 103 has a connecting hole 1031, and a connecting nut 3 is fixedly installed in the connecting hole 1031 of the first clamping member 1a or the second clamping member 1b. When installing the clamping ring 1, the connecting bolt passes through the connecting holes 1031 of the corresponding two connecting lugs 103 and is threaded to the connecting nut 3. By tightening the connecting bolt, the first clamping member 1a and the second clamping member 1b can be pulled closer and firmly connected together. In this way, the clamping ring 1 is clamped at the mouth of the cylinder body, making the installation of the clamping ring 1 simple, convenient and reliable.

[0035] In one embodiment, the first clamping member 1a and / or the second clamping member 1b are provided with a limiting protrusion 105, which is located on the outer wall of the pressing portion 101 of the first clamping member 1a and / or the second clamping member 1b.

[0036] In this embodiment, as Figure 1 , Figures 4 to 9 As shown, a limiting protrusion 105 is provided, and the limiting protrusion 105 is located at the middle position of the outer wall of the pressing part 101 of the second clamping member 1b.

[0037] In one embodiment, such as Figure 3 , Figure 10 and Figure 11 As shown, the end of the press-fit part 201 away from the grip part 203 has an abutment edge 2013 that is adapted to the outer wall of the top of the cylinder. The abutment edge 2013 enables the lifting handle 2 to make close contact with the outer wall of the top of the cylinder, ensuring that the lifting handle 2 is stable and reliable after assembly and is not easy to loosen or shake.

[0038] In one embodiment, such as Figure 1 , Figure 2 , Figures 4 to 10 As shown, the pressing part 201 has an assembly groove for positioning the clamping ring 1. The assembly groove is coaxial with the clearance hole, and the depth of the assembly groove is consistent with the thickness of the pressing part 101 of the clamping ring 1. This makes it easy to lock and fix the clamping ring 1 through the valve clearance port after the clamping ring 1 is placed in the assembly groove, and also makes the handle assembly aesthetically pleasing.

[0039] Based on the above structure, the handle assembly is simple in design. In use, the handle 2 is first placed on top of the cylinder body, so that the cylinder opening extends into the clearance hole of the handle 2. Then, the clamping ring 1 is fixedly installed onto the cylinder opening. The installation is simple, convenient, efficient, and quick. After installation, the pressing part 201 of the handle 2 is located between the clamping ring 1 and the cylinder body. The clamping hole of the clamping ring 1 is adapted to the cylinder opening and gradually narrows from top to bottom. This design ensures that the clamping ring 1 is not easily detached after installation. Furthermore, the anti-slip protrusions 104 on the inner wall of the clamping hole increase the contact friction between the clamping ring 1 and the mouth of the gas cylinder, further improving the installation firmness of the clamping ring 1 and making it even less likely to detach. In this way, the clamping ring 1 ensures that the lifting handle 2 is securely and reliably installed. During the process of moving the gas cylinder by lifting the handle 2, the lifting handle 2 will not detach, thus making the handling and moving of the gas cylinder safe, reliable, convenient, and practical.

[0040] This embodiment also discloses a gas cylinder, including the handle assembly described above, and a cylinder body. The top of the cylinder body has a bottle mouth, and a bottle valve is installed at the bottle mouth. The outer diameter of the bottle mouth gradually widens from bottom to top and is adapted to the clamping hole. The lifting handle 2 is located at the top of the cylinder body, and the bottle mouth extends into the clearance hole. The clamping ring 1 is fixedly installed on the bottle mouth by connecting bolts. The pressing part 201 is located between the clamping ring 1 and the cylinder body.

[0041] In one embodiment, the end of the press-fitting part 201 away from the gripping part 203 abuts against the top outer wall of the cylinder body via the abutting edge 2013, and the gas outlet of the cylinder valve corresponds to the valve clearance port of the lifting handle 2.

[0042] In this embodiment, the outer diameter of the cylinder body's opening gradually widens from bottom to top and is adapted to the clamping hole of the clamping ring 1. The handle assembly is installed and fixed on the top of the cylinder body based on the above-mentioned structure of the cylinder body. It is understood that, apart from the above-mentioned technical features, the other structures of the cylinder body are known to those skilled in the art. Therefore, the structure of the gas cylinder after the handle assembly is installed on the top of the cylinder body is not shown in the drawings. Those skilled in the art can clearly understand it based on the structure of the handle assembly and the cylinder body and the above-mentioned installation connection relationship.

[0043] Based on the above structure, the gas cylinder facilitates the installation, removal, and replacement of the handle assembly on the cylinder body. The handle assembly is firmly and reliably installed on the cylinder body, making it difficult to fall off or rotate. The handle assembly protects the cylinder valve without affecting the use of the cylinder, and facilitates the handling and movement of the gas cylinder, making the handling and movement of the gas cylinder convenient, labor-saving, safe, and reliable.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
