Description

Technical Field

[0001] The utility model belongs to the technical field of sealing parts, in particular to a mechanical sealing gland which is easy to disassemble. Background Art

[0002] Sealing refers to the components or measures that prevent fluids or solid particles from leaking from adjacent joint surfaces and prevent external impurities from invading the interior of machinery and equipment; when sealing containers or bottle mouths, machine seal caps are used. Machine seal caps are also called mechanical seal caps, which refer to a device used to seal containers or bottle mouths; machine seal caps are to install a matching seal on the bottle mouth or container mouth, and compress the seal onto the bottle mouth or container mouth by rotation or compression, so as to achieve the purpose of sealing and leak prevention; currently, there are several types of machine seal caps: extrusion type mechanical seal caps, twist bottle type mechanical seal caps and spiral mechanical seal caps.

[0003] After searching, a patent document with patent publication number CN218542575U discloses a machine seal cover that is easily disassembled. A disassembly groove is provided on the bottom surface of the machine seal cover. The disassembly groove is located close to the edge of the side wall of the machine seal cover. The opening of the disassembly groove is located on the side wall of the machine seal cover and the bottom surface of the machine seal cover. The machine seal cover has the advantages of simple structure, convenient maintenance and disassembly, and low manufacturing cost.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the process of disassembling the existing mechanical seal gland, two external disassembly tools need to be inserted into the disassembly grooves on both sides of the mechanical seal gland respectively, and the mechanical seal gland is lifted up with force to complete the disassembly of the mechanical seal gland. However, the above operation steps require the staff to operate the disassembly tools to disassemble and assemble the existing mechanical seal gland, which brings inconvenience to the disassembly of the existing mechanical seal gland, and increases the objects carried by the staff and the weight of the staff;

[0006] 2. During use, the existing machine-sealed gland improves the stability of the machine-sealed gland on the container and the sealing effect on the container mouth by connecting the threads on the inner wall of the machine-sealed gland with the threads on the bottleneck of the container. However, the existing machine-sealed gland is an integrated structure, so when the threads on the existing machine-sealed gland are damaged, the entirety of the gland will be discarded, which increases material waste.

[0007] To this end, we provide a machine seal gland that is easy to disassemble to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a machine seal gland that is easy to disassemble. By arranging a connection component and a shell component, the utility model solves the problem that the existing machine seal gland needs to be disassembled by controlling external disassembly tooling and is inconvenient to disassemble.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model discloses a mechanical sealing gland that is easy to disassemble, comprising a sealing gasket, wherein the lower surface of the sealing gasket abuts against the lower surface of the bottleneck of a container and is in communication with the container body, a connecting component is arranged on the peripheral side of the sealing gasket, a screw barrel in the connecting component is sleeved on the peripheral side of the sealing gasket, the screw barrel is threadedly connected to the outer peripheral side of the bottleneck of the container, an anti-slip sleeve is sleeved on the peripheral side wall of an insertion rod fixed in an annular array on the screw barrel; an outer shell component is arranged on the outer peripheral side of the screw barrel, an outer cylinder shell in the outer shell component is sleeved on the outer peripheral side of the screw barrel, and a limiting plate fixed on the outer cylinder shell is provided with insertion holes in an annular array, and the insertion holes are plugged with the insertion rod.

[0011] The utility model is further configured such that the outer cylinder shell is hollow, the limiting plate is hollow, and the inner diameter of the limiting plate is smaller than the inner diameter of the outer cylinder shell.

[0012] The utility model is further configured that the inner side wall of the outer cylinder shell is provided with a sealing sleeve, and the lower surface of the outer cylinder shell is provided with a sealing ring.

The above operation does not require the use of external disassembly tooling, which is convenient for the staff to disassemble the machine sealing cover.

[0020] 2. The utility model sets a shell assembly. After the sealing cover of the machine is disassembled, opposite external forces are applied to the outer cylinder shell and the screw cylinder to move the insertion rod out of the inside of the socket, thereby completing the separation between the shell assembly and the connecting assembly, making it convenient to replace the damaged connecting assembly, effectively reducing the number of structures of the sealing cover of the machine when it is replaced due to damage, and reducing material waste.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
