[0006] The technical solution adopted by the utility model to solve the above technical problem is: A cup lid structure includes an inner lid made of plastic and an outer lid sleeved on the inner lid. The outer lid is made of metal. A fixing ring made of metal is arranged between the inner lid and the outer lid. The fixing ring is sleeved on the inner lid. At least two clamping parts are arranged on the inner wall of the fixing ring. After the fixing ring is sleeved on the inner lid, the clamping parts are clamped on the inner lid to fix the fixing ring and the inner lid. The outer lid is sleeved on the fixing ring and fixedly connected to it.

[0007] A further preferred technical solution of the utility model is: The clamping part is an elastic barb, one end of the barb is connected to the fixing ring, and the other end extends towards the inside of the fixing ring.

[0008] A further preferred technical solution of the utility model is: A plurality of openings are provided at positions corresponding to the barbs on the fixing ring, and the barbs extend out from the openings towards the inside of the fixing ring.

[0009] A further preferred technical solution of the utility model is: The number of the barbs is four.

[0010] A further preferred technical solution of the utility model is: The barb is triangular in shape.

[0011] A further preferred technical solution of the present utility model is that: an annular step is provided on the inner cover. After the fixing ring is sleeved on the inner cover, the bottom end of the fixing ring abuts against the step.

[0012] A further preferred technical solution of the present utility model is that: the connection manner between the outer cover and the fixing ring is interference fit connection.

[0013] A further preferred technical solution of the present utility model is that: the materials of both the fixing ring and the outer cover are made of stainless steel.

[0014] Another theme of the present utility model, a cup, includes the above cup cover structure.

[0015] Compared with the prior art, the advantages of the present utility model are that a fixing ring is provided between the outer cover and the inner cover. The fixing ring is arranged on the inner cover and is snap-connected to the inner cover through the barbs on the inner wall of the fixing ring. The outer cover is interference-fitted with the fixing ring, making the cooperation between the outer cover, the fixing ring and the inner cover more firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will understand that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0026] It should be noted that similar reference numerals denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0027] As Figure 1 shown, the cup includes a cup body 2 and a cup cover, and the cup cover is threadedly connected to the cup body 2.

[0028] This embodiment mainly elaborates on the cup cover structure, which is as follows:

[0029] As Figure 5 shown, the cup cover structure includes an inner cover 6 and an outer cover 1 sleeved on the inner cover 6, and a fixed ring 4 is arranged between the inner cover 6 and the outer cover 1.

[0030] The inner cover 6 is integrally formed and made of plastic material.

[0031] A circular step 3 is provided on the inner cover 6. When the fixed ring 4 is sleeved on the inner cover 6, the bottom of the fixed ring 4 abuts against the step 3.

[0032] The fixed ring 4 is made of metal material. Preferably, the fixed ring 4 is made of stainless steel.

[0033] At least two clamping parts are arranged on the inner wall of the fixed ring 4. Preferably, four clamping parts are arranged on the inner wall of the fixed ring 4, and the four clamping parts are evenly distributed on the fixed ring 4 and are symmetric in pairs.

[0034] Preferably, the four clamping parts are all elastic barbs 5. One end of the barb 5 is connected to the fixed ring 4, and the other end extends towards the inside of the fixed ring 4 and abuts against the inner wall of the inner cover 6.

[0035] The shape of the barb 5 has various choices, such as rectangular shape, rhombus shape, triangular shape, etc. Preferably, the barb 5 on the fixed ring 4 is triangular.

[0036] As Figure 6 、 7 shown, several openings are provided on the circumferential side wall of the fixed ring 4, and the barb 5 extends out from the opening towards the inside of the fixed ring 4.

[0037] Preferably, a non-closed wire groove profile is cut out on the fixing ring 4 to form the above-mentioned opening 7 on the fixing ring 4. By pressing the cut-out part inside the opening inward, the cut-out part warps inward to form the above-mentioned barb 5.

[0038] After the fixing ring 4 is snap-fitted on the inner cover 6, the outer cover 1 is sleeved on the fixing ring 4, and the outer cover 1 and the fixing ring 4 are in press-fit interference fit.

[0039] The outer cover 1 is made of a metal material. Preferably, the outer cover 1 is made of a stainless steel material.

[0040] Both the outer cover 1 and the fixing ring 4 are made of stainless steel material. After the outer cover 1 is sleeved on the fixing ring 4, the outer cover 1 and the fixing ring 4 are pressed against each other. There is a stronger frictional force between the outer cover 1 and the fixing ring 4 made of the same stainless steel material, and the two are not easily separated.

[0041] As Figure 3 shown, the outer cover 1 is sleeved outside the fixing ring 4, and the bottom of the outer cover 1 also abuts against the annular step 3 of the inner cover 6.

[0042] During installation, the fixing ring 4 is sleeved on the inner cover 6, the bottom of the fixing ring 4 abuts against the annular step 3 of the inner cover 6, and the barb 5 is stuck on the inner wall of the inner cover 6 to fix the fixing ring 4 and the inner cover 6. The outer cover 1 is sleeved on the fixing ring 4, the bottom of the outer cover 1 abuts against the step 3 of the inner cover 6, and the outer cover 1 and the fixing ring 4 are connected in press-fit interference fit.

[0043] The above introduces the cup lid structure and the cup provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
