[0001] The utility model relates to the technical field of sealing appliances, in particular to a sealing cover for a barrel. Background Art
[0002] A sealing cover is a fitting used to close a container to prevent the leakage of its contents or the entry of external impurities. They are usually made of rubber, silica gel, plastic or other flexible materials to ensure good sealing performance. A sealing cover is a practical tool that protects the safety of products and the environment by providing an effective closure. When choosing a sealing cover, the durability, applicability of its material and its compatibility with the required closed container should be considered.
[0003] In the prior art, when transporting chemical supplies, workers will place some chemical drugs in the barrel body. However, since there are some volatile organic compounds in chemical supplies, when using a traditional sealing cover for sealing, the organic compounds will volatilize, which has an impact on the environment. At the same time, in high-temperature or low-temperature environments, under the cooperation of atmospheric pressure, the barrel body will deform, affecting its transportation.

In the middle of the mounting block, there is a through groove. At the lower part of the through groove, there is a one-way valve. At the lower part of the outer periphery of the one-way valve, there is a fixed plug, and at the lower part of the fixed plug, there are a plurality of uniformly distributed slot holes. At the upper part of the sealing cover main body, there is a mounting groove, and a sealing gasket is fitted and installed in the mounting groove;
[0007] Multiple groups of pressure auxiliary adjustment mechanisms, each group of the sealing cover main bodies are arranged in the inner cavity of the mounting block.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0023] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a sealing cover for a bucket, including: a bucket body 1, a sealing cover main body 2 is provided at the port of the bucket body 1, an installation block 4 is fixedly installed in the middle of the sealing cover main body 2, a through groove 5 is opened in the middle of the installation block 4, a one-way valve 6 is installed at the lower part of the through groove 5, a fixing plug 7 is provided at the lower part of the outer periphery of the one-way valve 6 and a plurality of uniformly distributed slot holes are opened at the lower part of the fixing plug 7, an installation groove 10 is provided at the upper part of the sealing cover main body 2, a sealing gasket 9 is fitted and installed in the installation groove 10, lifting rings 3 are fixedly installed at the upper middle parts of both sides of the bucket body 1. By connecting the threaded interface on the sealing cover main body 2 with the end of the bucket body 1, the sealing cover main body 2 can seal the bucket body 1. At the same time, the sealing cover main body 2 is provided with a through groove 5. Since the through groove 5 is provided with a one-way valve 6 and a fixing plug 7, the one-way valve 6 allows fluids such as gas to only flow from the inlet to the outlet, preventing the relevant fluid from flowing back into the inlet from the outlet, ensuring the one-way fluidity, and can avoid the volatilization of the organic matter contained in the bucket body 1 to the outside, which is beneficial to environmental protection. At the same time, it can ensure that the pressure in the bucket body 1 is slightly greater than the external pressure, avoiding the deformation of the bucket body 1 and affecting the normal use of the bucket body 1.
[0024] Multiple groups of pressure-assisted adjustment mechanisms 8, and each sealing cover body 2 is disposed in the inner cavity of the mounting block 4. Each group of pressure-assisted adjustment mechanisms 8 includes a limiting groove 804 and an opening groove 801. The limiting groove 804 is opened in the lower part of the inner cavity of the mounting block 4, and the opening groove 801 is opened in the upper part of the inner cavity of the mounting block 4. And the limiting grooves 804 and the opening grooves 801 in the same group correspond to each other one by one. Baffles 805 are provided in the limiting grooves 804. The sides of the baffles 805 and the limiting grooves 804 close to each other are chamfered. Wedge blocks are provided in the opening grooves 801, and limiting ball heads 802 are provided in the opening grooves 801. Each group of pressure-assisted adjustment mechanisms 8 further includes a movable rod 806. The movable rods 806 are respectively fixedly installed in the middle parts of the corresponding limiting ball heads 802 and the baffles 805. Abutting blocks 807 are movably installed on the upper parts of the outer peripheries of the movable rods 806. Springs 803 are fixedly installed on the lower parts of the abutting blocks 807. The tops of the springs 803 are fixedly installed on the upper parts of the corresponding baffles 805. The sealing cover body 2 is detachably connected to the barrel body 1 through threads. When the pressure in the barrel body is abnormal and exceeds the operating range of the one-way valve 6, at this time, the larger pressure inside the barrel body 1 will push the baffle 805 upward. Furthermore, the movable rod 806 will drive the corresponding baffle 805 to disengage from the limiting groove 804. At the same time, the limiting ball head 802 will move upward. At this time, the limiting groove 804 and the opening groove 801 will be opened simultaneously, and then the pressure in the barrel body 1 will be relieved, avoiding the explosion of the barrel body 1 due to excessive pressure inside the barrel body 1 under harsh environments such as high temperature, reducing potential safety hazards. And, the staff can select springs 803 of different material models and specifications, and thus can control the adaptability between the spring 803 and the internal pressure of the barrel body 1.
[0025] During the actual use process, the sealing cover body 2 is installed on the barrel body 1 through a threaded interface. Since the one-way valve 6, the fixed plug 7 and the through groove 5 are provided in the sealing cover body 2, it is possible to prevent the volatilization of the organic matter contained in the barrel body 1 and affect the environment. At the same time, it is possible to ensure that the pressure inside the barrel body 1 is slightly greater than the external pressure, which can prevent the barrel body 1 from deforming under environments such as high temperature and facilitate transportation. And, when the pressure inside the barrel body 1 is abnormal, the baffle 805 will disengage from the limiting groove 804. At the same time, the limiting ball head 802 will disengage from the opening groove 801, and then the pressure in the barrel body 1 can be relieved to avoid the explosion of the barrel body 1 due to excessive pressure inside the barrel body 1.
[0026] Although the above describes the illustrative specific embodiments of the present application for the convenience of those skilled in the art to understand the present application, the present application is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the appended claims, all application creations using the concept of the present application are within the scope of protection.
