Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel barrel structure technology, and in particular to a high-sealing stainless steel barrel matching plug. Background Technology
[0002] Stainless steel drums are commonly used storage and transportation containers in industrial and civilian fields. The sealing performance, operability, and durability of their matching plugs directly affect the safety and efficiency of use.
[0003] The existing stainless steel drum stopper technology still has many shortcomings in practical applications: In terms of sealing performance, traditional matching plugs mostly use narrow annular rubber rings as sealing elements. Their contact area with threaded plugs and barrel openings is limited, resulting in insufficient sealing fit. This makes them prone to liquid and gas leakage due to transportation vibrations or pressure changes.
[0004] In terms of ease of operation, the existing matching plugs have poor wrench compatibility, mostly corresponding to a single wrench size. When the matching tools are not available on site, it is difficult to complete the installation and disassembly efficiently. In addition, the narrow ring rubber ring does not have a dedicated disassembly and assembly structure. When replacing it, additional tools are required, which is cumbersome and can easily damage the seal.
[0005] In terms of structural durability, the threaded plug body is prone to deformation due to insufficient structural support during long-term use under stress, leading to premature scrapping of the matching plug.
[0006] To address this, a high-sealing stainless steel barrel stopper is proposed. Utility Model Content
[0007] The purpose of this invention is to solve the above problems by proposing a high-sealing stainless steel barrel plug that can simultaneously solve the problems of weak sealing, inconvenient operation, and easy structural damage.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing stainless steel barrel fitting plug, including a matching metal threaded plug, wherein a star-shaped groove metal part is welded and fixed inside the matching metal threaded plug, and an L-shaped sealing elastic rubber ring is fitted on the upper outer side of the matching metal threaded plug.
[0009] Preferably, the matching metal threaded plug has a threaded groove at its lower outer end for engaging with the screw thread of the stainless steel barrel opening.
[0010] Preferably, the metal part with the star-shaped slot is integrally formed by four C-shaped sleeves in a star shape; the slot widths at both ends of each C-shaped sleeve are the same, and the slot widths of different C-shaped sleeves are different, so as to adapt to various sizes of opening wrenches.
[0011] Preferably, the L-shaped sealing elastic rubber ring has two symmetrical lugs integrally formed on its edge.
[0012] The beneficial effects of this utility model are as follows: Through the design of the matching stopper for this stainless steel bucket, the specific beneficial effects are as follows: Enhanced sealing performance: The L-shaped sealing elastic rubber ring forms a larger contact area with the matching metal threaded plug and the barrel opening end face through its L-shaped cross-section. Compared with a narrow annular rubber ring, it can more effectively block liquid and gas leakage and improve the overall sealing performance.
[0013] Easier to operate: The metal parts with the cross-shaped slot can be used with various sizes of opening wrenches, making it easy to install and remove the matching metal threaded plug; at the same time, the symmetrical lug design of the L-shaped sealing elastic rubber ring makes it easier to install and remove the sealing ring, reducing the difficulty of operation.
[0014] More durable structure: The metal parts of the star-shaped groove are welded and fixed inside the matching metal threaded plug, which can enhance the overall structural strength of the threaded plug, reduce its deformation and scrapping caused by force or pressure changes during use, and extend the service life of the matching plug.
[0015] Superior compatibility: The threaded groove of the matching metal threaded plug precisely matches the screw ring at the barrel opening. Combined with the multi-specification wrench compatibility of the cross-shaped metal parts, it can meet the installation needs of different usage scenarios, improving overall compatibility.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] See Figure 1-4As shown, the matching metal threaded plug 1 serves as the main support structure of the entire set of plugs, undertaking the core function of connecting with the stainless steel barrel. The threaded groove at its lower outer end can precisely engage with the screw ring at the mouth of the stainless steel barrel, achieving initial fixation between the plug and the barrel body; at the same time, its interior provides a carrier for welding and fixing the star-shaped slotted metal part 2, while the upper outer end provides an installation position for the L-shaped sealing elastic rubber ring 3, integrating and supporting the other two key components.
[0020] The core functions of the star-shaped slot metal part 2 are threefold. First, it provides wrench compatibility. It consists of four C-shaped sleeves integrally formed in a star shape. Different C-shaped sleeves have different slot widths, which can accommodate various sizes of cap-opening wrenches. When opening the cap, the front end of the wrench can be inserted into the corresponding slot to apply force and rotate. Second, it assists in installation and disassembly. By cooperating with the wrench, it can drive the matching metal threaded plug 1 to rotate, realizing the installation or removal of the matching plug at the mouth of the barrel. Third, it provides structural reinforcement and support. After being welded and fixed inside the matching metal threaded plug 1, it can enhance the overall structural strength of the matching metal threaded plug 1 and reduce the probability of deformation and scrap due to changes in force or pressure during use.
[0021] The L-shaped sealing elastic rubber ring 3 primarily serves two functions: sealing and easy disassembly / reassembly. In terms of sealing, its L-shaped cross-section design allows it to form a tight seal with the upper outer side of the matching metal threaded plug 1 and the end face of the stainless steel barrel opening. Compared to a narrow annular rubber ring, it has a larger sealing contact area, effectively preventing liquid and gas leakage and improving overall sealing performance. In terms of disassembly / reassembly, its two symmetrically formed lugs provide leverage points for operation. When replacing it, simply pinch the lugs to easily remove it from or install it onto the matching metal threaded plug 1, making it more convenient than a narrow annular rubber ring.
[0022] The operation procedure of this utility model is as follows: When pre-installing the sealing ring, take the L-shaped sealing elastic rubber ring 3, align it with the installation position of the upper outer side of the matching metal threaded plug 1, and put it in place to ensure that the sealing ring fits the outer wall of the threaded plug without deviation.
[0023] When aligning the barrel opening, hold the matching metal threaded plug 1 with the L-shaped sealing elastic rubber ring 3 already installed, and align the threaded groove at the lower end of the plug with the screw ring at the opening of the stainless steel barrel, so that the axis of the threaded plug is aligned with the axis of the barrel opening.
[0024] During the initial screwing-in and fixing, manually rotate the matching metal threaded plug 1 to gradually engage the threaded groove at the lower outer end of the plug with the screw ring at the barrel opening, until the threaded plug can no longer be manually screwed in, thus completing the initial fixing.
[0025] When tightening with the help of a wrench, select a wrench of the appropriate size to the metal part 2 with the cross-shaped groove, and insert the front end of the wrench into the corresponding C-shaped ferrule groove of the metal part 2 with the cross-shaped groove; hold the end of the wrench and rotate the wrench clockwise to drive the matching metal threaded plug 1 to rotate synchronously until the threaded plug is fully screwed into the barrel opening and the L-shaped sealing elastic rubber ring 3 is tightly fitted with the end face of the barrel opening.
[0026] When removing the matching plug, insert the front end of the opening wrench into the matching C-shaped ferrule groove of the metal part 2 with the cross pattern, rotate the wrench counterclockwise to drive the matching metal threaded plug 1 out of the screw ring at the barrel opening, until the threaded plug can be manually removed.
[0027] When replacing the sealing ring, if the L-shaped sealing elastic rubber ring 3 needs to be replaced, pinch the two symmetrical lugs on the edge of the L-shaped sealing elastic rubber ring 3 and apply force away from the matching metal threaded plug 1 to remove the old L-shaped sealing elastic rubber ring 3; then, in the same way as the pre-installed sealing ring, put the new L-shaped sealing elastic rubber ring 3 onto the upper outer side of the matching metal threaded plug 1.
[0028] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention is defined by the appended claims and their equivalents.
