[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0014] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0015] The components of this application, such as the cylinder body 1, annular seat 2, protective cover 3, reinforcing rib 4, limiting baffle 5, receiving groove 6, horizontal shaft 7, limiting groove 8, first rubber pad 9, valve body 10, second rubber pad 11, valve seat 12, rubber ring 13, locking block 14, locking groove 15, pressing protrusion 16, and torsion spring 17, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0016] Example 1: Please see Figures 1-4 As shown, this utility model provides a steel cylinder with a sealing structure, comprising: The cylinder body 1 has a valve seat 12 fixedly connected to the middle of the top of the cylinder body 1, and a valve body 10 is threadedly connected to the upper end of the inner cavity of the valve seat 12. A ring seat 2 is fixedly connected to the top of the cylinder body 1. Limiting grooves 8 are opened at the lower ends of both sides of the outer surface of the ring seat 2. A slot 15 is opened at the upper end of the outer surface of the ring seat 2. A protective cover 3 is fitted on the outer surface of the ring seat 2. A locking block 14 is fixedly connected to the lower end of the inner cavity of the protective cover 3. The surface of the locking block 14 is movably connected to the surface of the slot 15. A receiving groove 6 is opened at the lower ends of both sides of the outer surface of the protective cover 3. A horizontal shaft 7 is fixedly connected to the middle end of the receiving groove 6. A limiting baffle 5 is movably inserted through the surface of the horizontal shaft 7. The lower end of the limiting baffle 5 is movably connected to the surface of the limiting groove 8. A torsion spring 17 is fixedly installed between the middle end of the limiting baffle 5 and the middle end of the horizontal shaft 7.
[0017] In this technical solution, during the transportation or handling of the cylinder body 1, the protective cover 3 around the annular seat 2 effectively protects the valve body 10, preventing damage caused by personnel's mistakes or negligence during handling. It also prevents dust from entering the valve body 10's interface and causing contamination when idle. The locking block 14 and locking groove 15 limit the vertical movement between the annular seat 2 and the protective cover 3. Furthermore, the receiving groove 6, horizontal shaft 7, torsion spring 17, limiting baffle 5, and limiting groove 8 limit the rotational direction between the annular seat 2 and the protective cover 3. When the cylinder body 1 needs to be used, the upper end of the limiting baffle 5 is pressed to rotate the limiting baffle 5 along the surface of the horizontal axis 7. At the same time, the torsion spring 17 is pressed until the lower end of the limiting baffle 5 can be disengaged from the surface of the limiting groove 8. Then, the operator rotates the protective cover 3 along the surface of the annular seat 2. The rotation of the protective cover 3 can drive the locking block 14 to rotate along the surface of the locking groove 15 until the locking block 14 can be aligned with the opening of the locking groove 15. Then, the operator can remove the protective cover 3 from the surface of the annular seat 2 by pulling it up. Then, the operator can connect the pipeline to the valve body 10 on the cylinder body 1.
[0018] It should be noted that in the initial state, the torsion spring 17 is already under force, so under the action of the reaction force of the torsion spring 17, the lower end of the limiting baffle 5 can be inserted into the limiting groove 8 with a certain force.
[0019] Example 2: Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a first rubber pad 9 is fixedly installed at the lower end of the inner cavity of the valve seat 12, the top of the first rubber pad 9 contacts the bottom of the valve body 10, a second rubber pad 11 is fixedly installed at the lower end of the valve body 10, the bottom of the second rubber pad 11 contacts the top of the valve seat 12, a rubber ring 13 is fixedly installed around the middle of the outer surface of the annular seat 2, the lower end of the inner cavity of the protective cover 3 contacts the surface of the rubber ring 13, a pressing protrusion 16 is fixedly connected to the upper end of the limiting baffle 5, a reinforcing rib 4 is fixedly connected to the upper end of the outer surface of the protective cover 3, and there are four slots 15 and four blocks 14.
[0020] In this technical solution, the sealing performance between the valve body 10 and the valve seat 12 is effectively improved by setting the first rubber pad 9 and the second rubber pad 11. The sealing performance between the annular seat 2 and the protective cover 3 is improved by setting the rubber ring 13. The pressing protrusion 16 makes it easy for personnel to press the upper end of the limiting baffle 5. The reinforcing rib 4 is used to strengthen the area around the protective cover 3.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
