Description

Technical Field

[0001] The utility model relates to the technical field of sealing of beverage containers, in particular to a sealing plug. Background Art

[0002] Existing beverage containers generally have a discharge port for pouring out beverages. For containers that require convenient output of beverages, a discharge port with a switching valve is generally opened at the bottom of the container, so that it is convenient to use and the corresponding switching valve can be opened to receive beverages.

[0003] Moreover, for a plunger-type switching valve, the sealing column of the switching valve generally controls the opening and closing of the discharge port by lifting, so the lifting channel for installing the sealing column is likely to smear the residues of the beverage on the inner wall of the lifting channel during repeated lifting activities, and the existing column-type sealing mechanism is not easy to disassemble and clean, and residues are likely to accumulate;

[0004] For the method of using a torsion spring to drive a seal to block the discharge port, since the torsion spring needs to be pre-compressed during the assembly process, and the torsion arms of the existing torsion springs have poor restraint to facilitate pre-assembly, it is easy to fall off when combined and assembled with other components, increasing the subsequent assembly difficulty.

[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] Referring to Figure 1 and Figure 2 An embodiment of the present utility model provides a sealing plug, which includes a sealing base 1, a sealing ring 2 and a torsion spring disposed on the sealing base 1. The sealing base 1 is provided with a mounting post 11 for mounting the sealing ring 2, and the sealing ring 2 is sleeved on the mounting post 11.

[0033] Wherein, one end of the sealing base 1 is provided with a rotating shaft mounting portion 12, and a rotating shaft hole is provided in the rotating shaft mounting portion 12 for mounting a base rotating shaft 3.

[0034] The front and rear end faces of the sealing base 1 are respectively a sealing end face 1a and a pressing end face 1b. The torsion spring includes an external torsion arm 41 for abutting against an external member, a spring portion 42 and a sealing torsion arm 43. The mounting post 11 is disposed at the sealing end face 1a.

[0035] Both ends of the rotating shaft mounting portion 12 are provided with spring socket columns 121, and the spring portion 42 of the torsion spring is sleeved on the spring socket columns 121.

[0036] The pressing end face 1b is provided with a clamping block 13 for clamping the sealing torsion arm 43, and the clamping block 13 is provided with a limiting groove 131 for restricting the movement of the sealing torsion arm along the pressing end face 1b.

[0037] The sealing torsion arm 43 includes a force arm section 431 and a clamping section 432 adapted to the shape of the limiting groove 131. The force arm section 431 is located on the outer side wall of the sealing base 1, and the clamping section 432 is placed in the limiting groove 131.

[0038] Preferably, the limiting groove 131 is L-shaped, and the clamping section 432 is L-shaped to be properly placed in the limiting groove 131. Correspondingly, the limiting groove 131 can also be non-linear shapes such as S-shaped, V-shaped, C-shaped, etc.

[0039] Specifically, the pressing end face 1b is provided with a traction portion for driving the sealing base 1 to rotate relative to the base rotating shaft 3. One end of the traction portion is connected to the sealing base 1, and the other end is provided with a traction rotating shaft for articulation with an external driving member, thereby simplifying the assembly process between the traction portion and the sealing base 1. At the same time, the integrated structure between the traction portion and the sealing base 1 also ensures the stability between the two.

[0040] In detail, the traction portion includes two symmetrically arranged traction arms 5, and a preset distance is left between the two traction arms 5 to form an activity space for the articulation activity of the external driving member.

[0041] Accordingly, in order to enhance the structural strength of the traction arm 5, on the pressure application end face 1b, an axial reinforcing plate 14 for enhancing the axial structural strength is provided between the two traction arms 5, and both ends of the axial reinforcing plate 14 are respectively connected to the inner side surfaces of the two traction arms 5.

[0042] Preferably, on the pressure application end face 1b, a radial reinforcing plate 15 for enhancing the radial structural strength is provided between the two traction arms 5, and the radial reinforcing plate 15 and the axial reinforcing plate 14 are arranged perpendicular to each other to form a cross structure. It should be noted that the axial and radial directions of the above-mentioned axial reinforcing plate 14 and radial reinforcing plate 15 are both relative to the base rotating shaft 3.

[0043] Furthermore, in order to improve the radial support strength of the radial reinforcing plate 15, a clamping block 13 is provided at the connection between the traction arm 5 and the pressure application end face 1b, and an arched support wall 16 for laterally supporting the radial reinforcing plate 15 is connected between the two clamping blocks 13, and one end of the radial reinforcing plate 15 is connected to the middle of the arched support wall 16.

[0044] On the other hand, in order to improve the stability of the pre-installed connection between the torsion spring and the sealing base 1, both ends of the rotating shaft mounting portion 12 are recessed inward relative to the two side walls of the sealing base 1 to form a spring activity space 1c for accommodating the spring portion 42; the spring activity space 1c is located between the two side walls of the sealing base 1, so that after the spring portion 42 and the clamping section 432 are installed, the force arm end can be attached to the side wall of the sealing base 1 by using the elastic force of the sealing torsion arm 43 itself, thereby increasing the difficulty of the external component accidentally hooking the sealing torsion arm 43 and causing it to fall off.

[0045] The sealing ring 2 is made of an elastic material. One end of the mounting post 11 is connected to the sealing base 1, and the other end is provided with an anti-detachment head 111 that prevents the sealing ring 2 from detaching from the mounting post 11, and the diameter of the anti-detachment head 111 is larger than the aperture of the sealing ring 2.

[0046] Due to the hard object setting of the mounting post 11, to a certain extent, the elastic deformation range of the sealing ring 2 is weakened. Therefore, the sealing ring 2 includes an embedding end 21 for embedding the sealed port and a limiting edge 22 for restricting the excessive embedding of the embedding end into the sealed port. The sealing ring 2 is an integral structure, and the sealing ring 2 is provided with a deformation annular groove 23 facing the sealing end face 1a to expand the radial deformation range of the embedding end 21; a deformation resistance rib 24 for hindering the deformation of the embedding end 21 is provided in the deformation annular groove 23 to prevent the opening of the deformation annular groove 23 from making the embedding end 21 too easy to deform and weakening the sealing performance.

[0047] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
