[0019] In the following, the application is further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.
[0020] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application.
[0021] The terms "first", "second", and the like in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.
[0022] As shown in Figure 1 and Figure 2 A screw cap, comprising an inner cover 2, an outer cover 6 and a sealing ring 1 provided on the inner cover 2, a stainless steel ring 4 is provided between the inner cover 2 and the outer cover 6, a plurality of inwardly protruding anti-dropping buckles 3 are provided on the stainless steel ring 4, the outer side wall of the inner cover 2 adopts a stepped ring structure, a plurality of clamping grooves 9 are provided on the side wall of the inner cover 2, and the anti-dropping buckles 3 are inserted into the clamping grooves 9 for reverse locking and fixing.
[0023] In the process of assembling the inner cover 2 and the outer cover 6, the existing connection structure is abandoned, and a stainless steel ring 4 is added between them for relative locking connection. Especially when the inner cover 2 is installed and fixed, the plurality of inwardly protruding anti-dropping buckles 3 on the stainless steel ring 4 are inserted into the clamping grooves 9 on the outer side wall of the inner cover 2 for directional buckling and locking, which can effectively avoid the loosening and falling of the installed inner cover 2. Moreover, the connection with the stainless steel ring 4 is more environmentally friendly, the production cost is lower, the process structure is simple, and there is basically no scrap situation in product production. The outer cover 6 is more convenient for secondary surface process treatment, and can better meet the diversified industrial design, so that the production and installation of the cup cover are more simple and beautiful.
[0024] Further improvement is that the stainless steel ring 4 comprises a fixed ring 42 in interference fit with the contact surface of the outer cover 6, and a first guide ring 41 provided on the fixed ring 42, and the first guide ring 41 and the outer cover 6 are in clearance fit.
[0025] When the stainless steel ring 4 is installed, the first guide ring 41 can facilitate the direct installation of the stainless steel ring 4 into the outer cover 6 during the early assembly. After complete installation, the fixed ring 42 part is in interference fit with the contact surface of the outer cover 6, which can realize firm positioning of the two and avoid loosening after installation.
[0026] Further improvement is that the anti-off buckle 3 is formed into a sheet-shaped rectangular structure with an inclined upward protrusion by stamping, and is arranged on the fixing ring 42; the anti-off buckle 3 is a stainless steel tube ring with a length of 0.8-1 mm, and the protruding length of the anti-off buckle 3 is not less than 1.5 mm.
[0027] The anti-off buckle 3 is formed into a sheet-shaped rectangular structure with an inclined upward protrusion by stamping, which is simpler and more convenient in production, and does not cause processing scrap, and has lower process difficulty. When the inner cover 2 is inserted, the anti-off buckle 3 can be deformed by extrusion and shrink, and can be quickly reset and buckled when moved to the buckle slot 9, which has lower operation difficulty and better assembly. Meanwhile, the anti-off buckle 3 is a stainless steel tube ring with a length of 0.8-1 mm, which can ensure rigidity and reduce thickness and weight, and the protruding length of the anti-off buckle 3 is not less than 1.5 mm, which can make the anti-off buckle 3 have an effective protruding height, so that the upper end of the anti-off buckle 3 can be inserted into the buckle slot 9. Generally, four anti-off buckles 3 are used.
[0028] Further improvement based on any of the above solutions is that the stainless steel ring 4 is matched with the inner cover 2 by a gap, which is simpler in installation and does not cause extrusion of the stainless steel ring 4 during assembly.
[0029] Further improvement is that the outer side of the inner cover 2 is formed into an assembly ring 21 and a second guide ring 22 by different outer diameters, and the buckle slot 9 is arranged outside the assembly ring 21; the second guide ring 22 is further provided with a guide groove 8 matched with the anti-off buckle 3.
[0030] During installation, the second guide ring 22 can more quickly assemble the inner cover 2, so that the anti-off buckle 3 is extruded for a shorter time and does not cause the anti-off buckle 3 to be insufficiently protruded to cause ineffective locking. In particular, the second guide ring 22 is further provided with a guide groove 8 matched with the anti-off buckle 3, and the anti-off buckle 3 is inserted into the guide groove 8 for assembly, which ensures the installation position and avoids extrusion of the anti-off buckle 3.
[0031] Further improvement is that the inner cover 2 is provided with a buffer pad 5 at the corner of the inner cover 2 and the outer cover 6; and the top of the inner cover 2 is provided with an upward protruding limiting convex ring 7, and the buffer pad 5 is sleeved on the limiting convex ring 7.
[0032] The combination of the limiting convex ring 7 and the buffer pad 5 can block the corner of the inner cover 2 and the outer cover 6, avoid deformation of the top of the inner cover 2 and the outer cover 6 due to excessive assembly, and ensure the installation depth of the inner cover 2 and the outer cover 6 and the position of the anti-off buckle 3, so that the tightness after installation is better.
[0033] The above embodiments are only the preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
