DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary description and cannot be understood as limiting the present patent.

[0030] In order to more concisely describe the present embodiment, some parts known to those skilled in the art but not related to the main content of the present invention are omitted in the drawings or descriptions. In addition, for the convenience of description, some parts in the drawings are omitted, enlarged or reduced, but they do not represent the size or entire structure of the actual product.

[0031] The utility model relates to a push-type cup cover that is convenient to open and close, such as Figure 1 , Figure 2 As shown, it includes an upper cover 1, an inner cover 2 and a hollow outer cover 3.

[0032] The outer cover 3 and the inner cover 2 are fixedly connected, such as Figure 4 , Figure 5 As shown, the outer cover 3 and the inner cover 2 are fixedly connected by the clamping strip 31 and the clamping slot 25. Alternatively, the inner wall of the outer cover 3 is provided with the clamping strip 31, and the outer wall of the inner cover 2 is provided with the clamping slot 25 correspondingly; or, conversely, the inner wall of the outer cover 3 is provided with the clamping slot, and the outer wall of the inner cover 2 is provided with the clamping strip.

[0033] The inner cover 2 is a cover body with an opening at the lower end, and at least two first through holes 21 are evenly arranged on the wall of the inner cover 2 .

[0034] like Figure 3 As shown, the upper cover 1 is a cover body with an opening at the lower end, and the upper cover 1 is provided with a push-pressing portion 11, which protrudes from the lower edge of the opening of the upper cover 1. The push-pressing portion 11 is provided with second through holes 12 or grooves, and the number of the second through holes 12 or grooves is equal to and corresponds to the first through holes 21.

[0035] The push-pressing portion 11 may be an insert plate arranged around the inner wall of the upper cover 1, and the insert plate is provided with second through holes 12 or grooves which correspond to the first through holes 21 one by one and are equal in number, or may be arranged as follows: Figure 3 The independent inserting strips shown correspond one-to-one to the first through holes 21, and each inserting strip is provided with a second through hole 12 or a groove.

[0036] An accommodating space for the push-pressing portion 11 is formed between the walls of the inner cover 2 and the outer cover 3 ; the upper cover 1 is slidably connected to the outer cover 3 , and the upper cover 1 can move up and down relative to the outer cover 3 .

[0037] The push-pressing portion 11 is disposed in the accommodation space, and a rolling body 22 is disposed in the space formed by the push-pressing portion 11 and the first through hole 21. The diameter of the first through hole 21 is smaller than the maximum diameter of the rolling body 22, so as to ensure that the rolling body 22 can partially protrude from the first through hole 21, but will not be squeezed out of the first through hole 21. Due to the fixed connection between the inner cover 1 and the outer cover 3, it is ensured that the rolling body 22 will not fall off. The rolling body 22 is usually a steel ball.

[0038] When the upper cover 1 is pressed down to make the first through hole 21 intersect with the second through hole 12 or the groove, the rolling body 22 rolls at the intersecting part of the first through hole 21 and the second through hole 12 or the groove, and the second through hole 12 or the groove can accommodate part of the rolling body 22 .

[0039] Combination Figure 1 , Figure 3As shown, a rolling body slide groove 13 is set below the second through hole 12 or groove of the pushing and pressing part 11; when the pushing and pressing part 11 chooses to set a groove, the depth of the slide groove 13 is shallower than the depth of the groove. The reason for this is that the groove is a retreat route prepared for the rolling body 22 to retreat from the first through hole 21, and the deeper groove is to allow more of the rolling body 22 to withdraw from the first through hole 21, so as to facilitate the opening of the cup cover; the slide groove 13 is designed to squeeze the rolling body 22, and the depth of the slide groove 13 is shallower, so that more of the rolling body 22 can protrude out of the first through hole 21, so that the cup cover can be closed more firmly; therefore, when the second through hole 12 or the groove is misaligned with the first through hole 21, the slide groove 13 squeezes the rolling body 22 out of the first through hole 21.

[0040] The inner cover 2 is elastically connected to the upper cover 1. The inner cover 2 is elastically connected to the upper cover 1 via a first return spring 51. Figure 1 As shown, a first spring seat 14 is disposed on the top of the upper cover 1, a second spring seat 24 is disposed at the third through hole 23 on the top of the inner cover 2, and two ends of the first return spring 51 are respectively sleeved on the first spring seat 24 and the second spring seat 14.

[0041] like Figure 6 As shown, it is a schematic diagram of the utility model used in the cup body 7. When the cup cover of the utility model needs to be covered on the cup mouth, the upper cover 1 is pressed downward, the first through hole 21 is connected with the second through hole 12 or the groove, and the rolling body 22 rolls toward the second through hole or groove 12 under the pressure of the cup mouth. The cup cover is covered on the cup mouth, and the hand is released. The upper cover 1 rises under the action of the first reset spring 51, and the second through hole or groove 12 is misaligned with the first through hole 21. The rolling body chute 13 squeezes the rolling body 22 outward from the first through hole 21, and the part of the rolling body 22 protruding from the first through hole 21 is stuck in the cup mouth slot 71. The lid is completely covered on the cup mouth and cannot be pulled out. When the cup cover needs to be opened, the upper cover 1 is pressed down, the first through hole 21 is connected with the second through hole or groove 12, and the outer cover 3 is pinched at the same time, and pulled upward together with the upper cover 1. The rolling body 22 rolls into the second through hole or groove 12 under the pressure of the cup mouth, and is separated from the cup mouth slot 71, and the cup cover is opened.

[0042] like Figure 1-3 and Figure 6 As shown, a third through hole 23 is set in the center of the top of the inner cover 2, and an exhaust device is set in the inner cover 2. The exhaust device includes a sealing cover 41 and a connecting rod 42. The connecting rod 42 passes through the third through hole 23 and is located in the space between the top of the inner cover 2 and the top of the upper cover 1. The sealing cover 41 is located below the third through hole 23.

[0043] A limiting portion 43 is provided at the top of the connecting rod 42 , and a second return spring 52 is provided and sleeved on the connecting rod 42 . The second return spring 52 is located between the limiting portion 43 and the top of the inner cover 2 .

[0044] In this way, when the cup cover is opened, while the upper cover 1 is pressed downward, the top of the upper cover 1 presses the connecting rod 42 and moves downward together, so that the sealing cover 41 is moved away from the third through hole 23 to achieve exhaust.

[0045] In order to achieve heat preservation and sealing effect, a sealing ring installation part 6 is provided in the inner cover 1, and a sealing ring 62 is sleeved on the bottom of the sealing ring installation part 6. A third through hole 23 is provided in the center of the top of the inner cover 2, and a fourth through hole 61 penetrating the third through hole 23 is provided in the center of the sealing ring installation part 6; the connecting rod 42 of the exhaust device passes through the fourth through hole 61 and the third through hole 23 and is located in the space between the top of the inner cover 2 and the top of the upper cover 1, and the sealing cover 41 is located below the fourth through hole 61. In this way, when the cup lid is opened, while the upper cover 1 is pressed downward, the top of the upper cover 1 presses the connecting rod 42 and moves downward together, so that the sealing cover 41 is moved away from the fourth through hole 61 to achieve exhaust.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
