Description

Technical Field

[0001] This utility model relates to the technical field of gas cylinder protection equipment, specifically a protective cover for gas cylinders. Background Technology

[0002] Generally, seamless steel acetylene cylinders are equipped with valve protection caps at the neck to prevent damage to the valve during handling, which could cause difficulties in use or lead to leaks and explosions. Ordinary valve protection caps are screwed onto the neck of the cylinder via threads at the bottom or welded directly to the top. These caps are difficult to replace and have a short lifespan, leaving many acetylene cylinders in a dangerous, bare-capped state during actual use. Utility Model Content

[0003] The purpose of this invention is to provide a protective cover for gas cylinders to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for a gas cylinder, comprising a connecting part threadedly connected to the cylinder neck, a supporting part on the connecting part, a protective cover slidably mounted on the outside of the supporting part, and both the connecting part and the protective cover having clearance areas; a spring is also provided between the supporting part and the protective cover, and the protective cover is moved upward by the spring; the side of the protective cover away from the connecting part is an open structure, so that the valve on the cylinder is exposed when the protective cover moves downward.

[0005] As a preferred technical solution of this utility model: the back of the protective cover is also provided with an internal threaded hole, and the support part is also provided with a waist-shaped groove corresponding to the position of the internal threaded hole; the bolt is provided to pass through the internal threaded hole and then through the waist-shaped groove so that the bolt guides the protective cover to slide.

[0006] As a preferred technical solution of this utility model: the outer wall surface of the support is further provided with a guide post, and the inner wall surface of the protective cover is further provided with a guide groove that is compatible with the guide post.

[0007] As a preferred technical solution of this utility model: the guide post is further provided with a countersunk hole, wherein one end of the spring is inserted into the countersunk hole.

[0008] As a preferred technical solution of this utility model: the inner wall surface of the protective cover is further provided with a support platform, and the end of the spring away from the connecting part abuts against the support platform.

[0009] The beneficial effects of this utility model using the above technical solution are as follows: 1. Due to the provision of a connecting part, the connecting part can be installed at the mouth of the cylinder. Simultaneously, a support part is provided on the connecting part, and the protective cover slides on the support part. Therefore, by pulling the protective cover upwards until it covers the valve at the cylinder mouth, the valve at the cylinder mouth can be protected. In particular, because the connecting part is threadedly connected to the cylinder mouth, firstly, the connecting part can be reliably fixed to the cylinder mouth when there is no external force; secondly, when the connecting part is rotated until the clearance area is misaligned with the valve's outlet, the valve's outlet can also be protected.

[0010] 2. Because the upper part of the protective cover is an open structure, pressing the protective cover downwards until the valve handle is completely exposed allows the valve to be opened and closed without disassembling the protective cover. In particular, when there is no external force, the protective cover can automatically move upwards under the action of the spring, thereby causing the protective cover to cover the valve at the bottle mouth, so as to achieve automatic protection of the valve.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0020] Please see Figure 1-7 This utility model provides an embodiment of a protective cover for a gas cylinder, comprising a connecting part 1 threadedly connected to the mouth of a gas cylinder, a supporting part 2 provided on the connecting part 1, a protective cover 7 slidably mounted on the outside of the supporting part 2, and both the connecting part 1 and the protective cover 7 are provided with clearance areas 8; a spring 4 is also provided between the supporting part 2 and the protective cover 7, and the protective cover 7 is moved upward by the spring 4; the side of the protective cover 7 away from the connecting part 1 is an open structure, so that the valve on the gas cylinder is exposed when the protective cover 7 moves downward.

[0021] In summary, due to the provision of the connecting part 1, it can be installed at the mouth of the cylinder. The connecting part 1 also has a support part 2, and the protective cover 7 slides on the support part 2. Therefore, by pulling the protective cover 7 upwards until it covers the valve at the cylinder mouth, the valve at the cylinder mouth can be protected. In particular, as... Figure 7 As shown, since the connecting part 1 is threadedly connected to the mouth of the gas cylinder, firstly, the connecting part 1 can be reliably fixed to the mouth of the cylinder when there is no external force; secondly, when the connecting part 1 is rotated until the clearance area 8 is misaligned with the outlet of the valve, the outlet of the valve can be protected.

[0022] At the same time, such as Figure 6 As shown, since the upper end of the protective cover 7 is an open structure, pressing the protective cover 7 downwards until the valve handle is completely exposed allows the valve to be opened and closed without disassembling the protective cover 7. In particular, when there is no external force, the protective cover 7 can automatically move upwards under the action of the spring 4, thereby causing the protective cover 7 to cover the valve at the bottle mouth, so as to achieve automatic protection of the valve.

[0023] Furthermore, since the back of the protective cover 7 is provided with an internal threaded hole 5, and the support part 2 is provided with a waist-shaped groove 3 corresponding to the position of the internal threaded hole 5; the bolt 6 passes through the internal threaded hole 5 and then through the waist-shaped groove 3 to guide the protective cover 7 to slide. Therefore, when one end of the bolt 6 is inserted into the waist-shaped groove 3, the waist-shaped groove 3 can be used to limit the sliding distance of the bolt 6, thereby preventing the protective cover 7 from separating from the support part 2 due to excessive upward sliding.

[0024] Based on the above solution, since the outer wall of the support part 2 is also provided with guide posts 9, and the inner wall of the protective cover 7 is also provided with guide grooves 10 that are adapted to the guide posts 9, the mutual cooperation between the guide posts 9 and the guide grooves 10 can be used to ensure the directional sliding of the protective cover 7 and avoid the problem of axial rotation of the protective cover 7 on the connecting part 2.

[0025] Furthermore, since the guide post 9 is also provided with a countersunk hole 11, one end of the spring 4 is inserted into the countersunk hole 11, thus ensuring the stability of the spring 4 during operation and thereby improving the automatic reset capability of the protective cover 7.

[0026] In addition, since the inner wall of the protective cover 7 is also provided with a support platform 8, and the end of the spring 4 away from the connecting part 1 abuts against the support platform 8, the lower end surface of the support platform 8 can prevent the protective cover 7 from moving further down after it comes into contact with the upper end surface of the support part 2.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
