detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figures 1 to 3, a sealing device for a can mouth 1 according to a preferred embodiment of the present invention includes a sealing cover 2, a stepped can mouth 1, and a can plug 3 matching the can mouth 1 , the outer wall of the can plug 3 is concave to form at least one concave surface 31 that abuts against the inner wall of the can mouth 1, and the outer peripheral edge of the bottom of the can plug 3 protrudes to form an undercut that is buckled with the bottom end surface of the can plug 3 32. The top of the can plug 3 and the inner wall of the can mouth 1 form a groove, the sealing cover 2 is fixed on the top of the can mouth 1, and the inner side of the sealing cover 2 is provided with a groove that is plugged and fitted with the groove. The boss 21.

Since the can plug 3 is matched with the can mouth 1, and the can mouth 1 is stepped, therefore, when in use, only the can plug 3 needs to be firmly inserted into the can mouth 1 and the can mouth The can plug 3 is embedded in the can mouth, and the concave surface 31 of the outer wall of the can plug 3 can abut against the inner wall of the can mouth 1, and the undercut 32 formed on the outer peripheral edge of the bottom of the can plug 3 is on the concave surface. 31 is fastened with the bottom end surface of the tank plug 3, so that the tank plug 3 is well fixed on the tank mouth 1, and it is ensured that the concave surface 31 is tight to the inner wall of the tank mouth 1 close fit, so as to play a certain sealing effect; because the can plug 3 is embedded in the can mouth 1, therefore, the top of the can plug 3 can be enclosed with the inner wall of the can mouth 1 groove, and after sealing the sealing cover 2 to the top of the tank mouth 1, the boss 21 can be inserted into the groove, therefore, the sealing cover 2 can not only prevent the The tank plug 3 is loosened to ensure the tightness of the tank plug 3, and a seal can be formed again between the tank plug 3 and the tank mouth 1, thereby greatly improving the tightness of the tank mouth 1 sealing device.

In order to further improve the sealing performance of the sealing device of the tank mouth 1, in one embodiment, as shown in Figure 1 and Figure 2, an annular accommodating groove 211, and make said accommodating groove 211 surround the top of said tank stopper 3, and said accommodating groove 211 is embedded with sealing ring 5, wherein said accommodating groove 211 can be formed by said boss 21 concave , and correspondingly, the sealing ring 5 is connected with the inner wall of the tank mouth 1; of course, the accommodating groove 211 can also be formed by the inner wall of the tank mouth 1 being concavely formed, and correspondingly, the sealing ring 5 is connected with the inner wall of the tank mouth 1 The boss 21 is connected. In this way, when the sealing cap 2 is fixed on the top of the tank mouth 1 , the accommodating groove 211 can be closely attached to the sealing ring 5 . Since the sealing ring 5 is embedded in the receiving groove 211 and surrounds the top of the can plug 3, and the sealing ring 5 is connected with the boss 21 or the inner wall of the can mouth 1, therefore, When there is liquid flowing out between the outer wall of the can plug 3 and the inner wall of the can mouth 1, the concavo-convex arrangement of the sealing ring 5 and the accommodating groove 211 can be connected between the top of the can plug 3 and the sealing cover 2. A layer of sealing is formed between them again, thereby greatly improving the sealing effect of the sealing device of the tank mouth 1 . Exemplarily, the connection between the sealing ring 5 and the inner wall of the tank mouth 1 , or between the sealing ring 5 and the boss 21 can be realized by welding or other methods, which also facilitates the unified processing of the tank mouth 1 . Of course, in order to better ensure the sealing effect of the sealing device of the tank mouth 1, more than two sealing rings 5 and receiving grooves 211 may also be provided according to actual needs, and the sealing ring 5 and the receiving groove 211 They are arranged concentrically with the central axis of the can plug 3 as the center, and the receiving groove 211 corresponds to the position of the sealing ring 5 .

In order to facilitate the insertion of the tank plug 3 into the tank mouth 1 and reduce wear on the inner wall of the tank mouth 1, as shown in Figure 3, the bottom surface of the tank plug 3 can also be concaved to form at least one buffer groove 33 In this way, the elasticity of the bottom of the can plug 3 can be enhanced. During the process of inserting the can plug 3 into the stepped can mouth 1, the bottom of the can stopper 3 can form a certain shape along with the shape of the can mouth 1. shrink, so as to conveniently fasten the barb at the bottom of the can plug 3 with the bottom end surface of the can mouth 1 .

For the convenience of installation, the top surface of the tank plug 3 can also be concaved to form a mounting groove 34, and the mounting groove 34 can be easily grasped by a machine or a human hand, so that when inserting the tank plug 3 or pulling out the Apply force at 3 o'clock. Certainly, a pull ring may also be provided in the installation groove 34 .

In addition, in order to improve the strength of the top of the can plug 3 and make the outer wall of the can plug 3 tightly fit with the inner wall of the can mouth 1, a side of the boss 21 facing the can plug 3 can be provided The protrusion 212 corresponding to the shape of the installation groove 34, as shown in Fig. 2 and Fig. 3, in this way, when in use, the protrusion 212 can be inserted into the installation groove 34, so that not only the sealing cover 2 can It is better fixed with the tank plug 3, and it can avoid the deformation of the tank plug 3 caused by the long-term plugging and unplugging of the tank plug 3, so that there is a gap with the inner wall of the tank mouth 1, thereby ensuring that the tank mouth 1 The tightness of the sealing device during long-term use. Further, both the mounting groove 34 and the protruding post 212 can be arranged in a ring shape, and the protruding post 212 can be threadedly connected to the mounting groove 34, so that not only the sealing cover can be better fixed 2. When the sealing device of the tank mouth 1 is opened, the tank plug 3 can be pulled out together by opening the sealing cover 2 .

Further, on the basis of the above configuration, the sealing cover 2 , the boss 21 and the boss 212 are integrated by injection molding technology to facilitate processing and reduce production costs. In order to avoid damage to the sealing cover 2, as shown in Figure 4, a metal cover 4 can also be sealed at the top of the sealing cover 2 to improve the life of the sealing device of the can mouth 1. The surface of the metal cover 4 is provided with an easy-to-pull ring 41, and a lifting ring is provided on the top surface of the sealing cover 2. In this way, when in use, it is not necessary to disassemble the metal cover 4, and it can be easily opened by tearing the easy-to-pull ring 41 The metal cover 4. Since the area of the easy-to-open ring 41 is larger than the top surface area of the sealing cover 4, after the easy-to-open ring 41 is torn off, the sealing cover 2 can be easily pulled out or taken out by the lifting ring. The metal cover 4 and the easy-to-open ring 41 can be made of conventional aluminum materials, and of course other metal materials can also be used as required.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and replacements can also be made. And replacement should also be regarded as the protection scope of the present utility model.
