Description

Technical Field

[0001] The utility model relates to the technical field of sealing covers, in particular to an anti-loosening sealing cover for a pressure container. Background Art

[0002] A pressure vessel is a device designed to withstand internal pressure and store liquids or gases in it. They are commonly used in the industrial field to store, process or transport various substances, such as chemicals, oil and gas. Pressure vessels must meet strict design and manufacturing standards to ensure safe operation and prevent leakage or explosion. In order to ensure that the container remains safely sealed when under pressure, it is often closed with a non-loosening sealing cover. The sealing cover usually adopts special structures or mechanisms, such as threads, pins, pins or pressure locking devices, to ensure that the cover remains safely sealed when the container is under pressure.

[0003] The traditional anti-loosening sealing cover of the pressure vessel is designed by setting a thread at the bottom of the sealing cover and opening a corresponding thread groove inside the container. This design enables the sealing cover to form a tighter combination with the container when it is connected to the container by twisting, thereby effectively preventing loosening problems caused by factors such as vibration and temperature changes.

[0004] Although the traditional method has effectively prevented the loosening problem caused by factors such as vibration and temperature change, it does not take into account the problem that when the sealing cover is connected to the container by twisting, because the sealing cover is generally large in size and has a certain weight, when twisting, the entire sealing cover needs to be rotated, which is troublesome, time-consuming and labor-intensive. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an anti-loosening sealing cover for a pressure vessel, aiming to improve the problem that the sealing cover of some pressure vessels has a relatively simple structure and the barrel cover is fixed by threaded connection, which is time-consuming and labor-intensive.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure vessel anti-loosening sealing cover, comprising a barrel, a placing table is arranged inside the barrel, a groove is opened inside the barrel, a barrel cover is arranged inside the barrel, an auxiliary component is arranged on the upper surface of the barrel cover, a fixing frame is fixedly connected to the lower surface of the barrel cover, a slide plate is fixedly connected to the fixing frame, a slider is slidably connected to the slide plate, a limiting column is fixedly connected to the upper surface of the slider, a rotating plate is rotatably connected to the fixing frame, a limiting groove is opened inside the rotating plate, a side wall of the limiting column is slidably connected to the inside of the limiting groove, a side wall of the slider is slidably connected to the inside of the groove, a twist is rotatably connected to the inside of the barrel cover, and the lower surface of the twist is fixedly connected to the upper surface of the rotating plate.

[0007] Furthermore, the auxiliary component includes a handle, and the lower surface of the handle is fixedly connected to the upper surface of the barrel cover.

[0008] Furthermore, a concave hole is opened inside the barrel, and a clamping column is fixedly connected to the lower surface of the barrel cover.

[0009] Furthermore, the side wall of the clamping column is slidably connected inside the concave hole.

[0010] Furthermore, a sealing ring 1 is fixedly connected to the upper surface of the placement table, and a sealing ring 2 is fixedly connected to the side wall of the barrel cover.

[0011] Furthermore, the outer diameter of the sealing ring 1 matches the inner diameter of the sealing ring 2, and a side wall of the sealing ring is slidably connected to the inside of the sealing ring 2.

[0012] Furthermore, the side wall of the barrel cover is slidably connected to the inside of the barrel, and the side wall of the barrel cover is in contact with the placement table.

[0013] The utility model has the following beneficial effects:

[0014] 1.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a pressure vessel anti-loosening sealing cover, including a barrel 1, a placing table 2 is arranged inside the barrel 1, a groove 3 is opened inside the barrel 1, a barrel cover 5 is arranged inside the barrel 1, an auxiliary component is arranged on the upper surface of the barrel cover 5, a fixed frame 7 is fixedly connected to the lower surface of the barrel cover 5, a slide plate 8 is fixedly connected inside the fixed frame 7, a slider 9 is slidably connected inside the slide plate 8, a limiting column 10 is fixedly connected to the upper surface of the slider 9, a rotating plate 11 is rotatably connected inside the fixed frame 7, a limiting groove 12 is opened inside the rotating plate 11, a side wall of the limiting column 10 is slidably connected inside the limiting groove 12, a side wall of the slider 9 is slidably connected inside the groove 3, a twist 13 is rotatably connected inside the barrel cover 5, and the lower surface of the twist 13 is fixedly connected to the upper surface of the rotating plate 11, and the auxiliary component includes a handle 6, and the lower surface of the handle 6 is fixedly connected to the upper surface of the barrel cover 5.

[0023] When installing the barrel cover 5, first, place the barrel cover 5 inside the barrel 1, and then rotate the knob 13 to drive the rotating plate 11 to rotate. During the rotation of the rotating plate 11, under the action of the limiting groove 12, the slider 9 is driven by the limiting column 10 to slide inside the slide plate 8. As the rotating plate 11 continues to rotate, the slider 9 is gradually inserted into the groove 3 to fix the barrel cover 5, ensuring that after the slider 9 is inserted into the groove 3, the barrel cover 5 can be tightly pressed against the mouth of the barrel 1 to form an effective seal.

[0024] Reference Figure 1 - Figure 3A concave hole 4 is opened inside the barrel 1, a clamping column 16 is fixedly connected to the lower surface of the barrel cover 5, and the side wall of the clamping column 16 is slidably connected to the inside of the concave hole 4, a sealing ring 14 is fixedly connected to the upper surface of the placement table 2, and a sealing ring 2 15 is fixedly connected to the side wall of the barrel cover 5. The outer diameter of the sealing ring 14 is consistent with the inner diameter of the sealing ring 2 15, and the side wall of the sealing ring 14 is slidably connected to the inside of the sealing ring 2 15, and the side wall of the barrel cover 5 is slidably connected to the inside of the barrel 1, and the side wall of the barrel cover 5 is in contact with the placement table 2.

[0025] When the barrel 1 needs to be closed, the operator will place the barrel cover 5 on the top of the barrel 1, and then press the barrel cover 5 downward to insert the clamping column 16 into the inside of the concave hole 4. This action not only fixes the barrel cover 5 on the barrel 1, but also starts the sealing process. As the barrel cover 5 is further pressed down, the sealing ring 14 on the surface of the placement table 2 gradually moves to the inside of the sealing ring 2 15 and fits tightly with it. When they fit tightly, a barrier will be formed to effectively prevent the substance in the barrel 1 from leaking into the external environment.

[0026] Working principle: When the barrel 1 needs to be closed, the barrel cover 5 is placed on the top of the barrel 1 and then pressed downward to insert the clamping column 16 into the inside of the concave hole 4. When the barrel cover 5 is completely moved into the barrel 1, the sealing ring 14 on the surface of the placement table 2 moves to the inside of the sealing ring 2 15 and fits with it. At this time, the knob 13 is rotated to drive the rotating plate 11 to rotate, and under the action of the limiting groove 12, the slider 9 is driven by the limiting column 10 to slide inside the slide plate 8 and gradually inserted into the inside of the groove 3, so as to fix the barrel cover 5 and make the sealing ring 2 15 fit more closely with the sealing ring 1 14, thereby ensuring the sealing of the equipment.
