[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , in the embodiment of the present invention, it includes a cup body 5, a base 1, a handle 2, a transmission part 3 and a locking part 4. An external thread is coaxially provided at the top of the cup body 5, and an internal thread is coaxially provided on the inner side surface of the base 1. The base 1 and the cup body 5 are hermetically connected to each other by means of screw connection.

[0024] The base 1 is integrally in the shape of a cylinder. A convex boss 11 is fixedly installed in the middle position of the upper end surface of the base 1. A direct drinking port 111 is opened on the upper surface of the boss 11, and the boss 11 and the base 1 are integrally formed. Fixed plates 12 are arranged at intervals on both sides of the boss 11 and the boss 11. And the two fixed plates 12 are symmetrically arranged on both sides of the boss 11. Guide bars 122 are fixedly installed on the opposite side surfaces of the two fixed plates 12, and the length directions of the two guide bars 122 are both horizontally arranged. Positioning holes 121 are opened at positions close to the bottom of the two fixed plates 12, and the axially horizontally arranged positioning holes 121 are two-stage stepped holes that gradually narrow from the outside to the inside. A limiting groove 1211 is opened at the uppermost end of the positioning hole 121.

[0025] A two-stage stepped shaft 33 that is coaxially rotatably arranged in the positioning hole 121 and cooperates with it passes through the front end of the positioning hole 121 and is coaxially fixed to the driving gear 32. When the two-stage stepped shaft 33 is inserted into the positioning hole 121, the shaft shoulder of the two-stage stepped shaft 33 abuts against the hole shoulder of the positioning hole 121. At this time, the driving gear 32 passes through the positioning hole 121 and enters the gap between the fixed plate 12 and the boss 11, and the driving gear 32 and the driven rack 34 are in a state of meshing and driving with each other. A transition groove 332 and a clamping groove 333 are formed in the tail end of the two-stage stepped shaft 33, and the transition groove 332 and the clamping groove 333 are arranged symmetrically with the axis of the two-stage stepped shaft 33 as the axis of symmetry.

[0026] A sliding cover 13 is also slidably arranged on the upper table surface of the boss 11. During the sliding process of the sliding cover 13, the lower cover surface of the sliding cover 13 fits closely with the upper table surface of the boss 11, so that when the sliding cover 13 slides to the direct drinking port 111, it can cover the direct drinking port 111 from top to bottom to seal the direct drinking port 111. At the same time, in order to improve the sealing performance, a sealing rubber is also provided at the position where the lower cover surface of the sliding cover 13 cooperates with the direct drinking port 111, and then the sealing performance is improved through the extrusion deformation of the sealing rubber at the direct drinking port 111. At the same time, a pressure relief hole is also provided on the upper table surface of the boss 11, and a valve-type one-way pressure relief valve is installed in the pressure relief hole.

[0027] The two side surfaces of the sliding cover 13 are respectively in close contact with the inner side surfaces of the two fixed plates 12, and guiding grooves 131 are formed on both side surfaces of the sliding cover 13, and two guiding strips 122 are slidably engaged with the two guiding grooves 131. Through the sliding cooperation of the guiding grooves 131 and the guiding strips 122, the sliding stability of the sliding cover 13 can be improved. A driven rack 34 is fixedly installed on the sliding cover 13, and the length direction of the driven rack 34 is parallel to the reciprocating linear sliding direction of the sliding cover 13. And the driven rack 34 is located in the gap between the fixed plate 12 and the boss 11.

[0028] The handle 2 is composed of a cross bar 21 and two vertical bars 22 respectively and vertically fixed at both ends of the cross bar 21. The formed handle 2 is in the shape of a U-shaped bent rod. Moreover, both the vertical bar 22 and the cross bar 21 are of hollow structure, so the formed handle 2 is a hollow shell. Positioning shafts 31 are installed on the inner side surfaces at the front ends of the two vertical bars 22, and the two positioning shafts 31 on the two vertical bars 22 are coaxially arranged. Chute grooves 311 are formed on the outer circumferential surfaces of the two positioning shafts 31, and the openings of the two chute grooves 311 communicate with the rod cavities of the corresponding vertical bars 22. Cards 312 are installed on the positioning shafts 31. The groove length directions of the two chute grooves 311 are parallel to the rod length direction of the vertical bar 22, and the groove ends of the two chute grooves 311 close to the cross bar 21 are open ends. Guide grooves 221 are formed on the inner side surfaces of the two vertical bars 22, and the guide grooves 221 communicate with the rod cavities of the vertical bars 22. Pressing holes 211 are formed on the upper side surface of the cross bar 21.

[0029] The two pressing rods 411 and the connecting rod 43 cooperate with each other to form a U-shaped bent rod. Limit pieces 412 are fixedly installed at the bottom ends of the two pressing rods 411. Moreover, the thickness of the limit piece 412 is the same as the groove widths of the chute groove 311 and the guide groove 221. The diameter of the pressing rod 411 is the same as the inner diameter of the rod cavity of the vertical bar 22 to prevent the pressing rod 411 from shaking in the rod cavity during use.

[0030] When assembling the present utility model, first place the base 1 on the desktop, and then through the cooperation of the guide groove 131 and the guide strip 122, slidably install the sliding cover 13 on the boss 11, and make the sliding cover 13 cover the direct drinking port 111 at this time. Then install the driving gear 32 in the positioning hole 121 through the two-stage stepped shaft 33. When installing, first make the transition groove 332 on the top and the card slot 333 on the bottom, and then push the driving gear 32 into the positioning hole 121, and make the driving gear 32 mesh with the driven rack 34 on the sliding cover 13 that currently covers the direct drinking port 111.

[0031] Next, insert the two return springs into the rod cavities of the two vertical rods 22 respectively. Then insert the pressing rod 411 through the pressing hole 211 on the cross bar 21 into the vertical rod 22, and the limiting piece 412 slides along the guiding groove 221 into the sliding groove 311. At this time, without pressing, a part of the limiting piece 412 is located outside the sliding groove 311. Then press the pressing block 431 at the top of the connecting rod 43 to press the limiting piece 412 completely into the sliding groove 311. Then align the positioning shaft 31 on one side with the through hole 331 and insert the positioning shaft 31 into the through hole 331. Then gently bend the other vertical rod 22 outwards and insert the other positioning shaft 31 into the through hole 331. During this process, the card 312 of the positioning shaft 31 is inserted into the card slot 333, and then release the pressing block 431. At this time, under the action of the return spring, the limiting piece 412 passes through the transition groove 332 and is inserted into the limiting groove 1211 and abuts against the bottom of the limiting groove 1211. At this time, the limiting piece 412 straddles the sliding groove 311, the transition groove 332 and the limiting groove 1211, thereby locking the position of the handle 2. At this time, the handle 2 is in the vertical state. Thus, the cup lid is assembled. Then cover the cup lid on the cup body 5 and it can be used.

[0032] During the use process, first press the pressing block 431 to retract the limiting piece 412 into the sliding groove 311. Then rotate the handle 2 and release the pressing block 431. At this time, the front end of the limiting piece 412 abuts against the hole wall of the positioning hole 121. At the same time, the sliding cover 13 slides to open the direct drinking port 111 under the driving action of the driving gear 32. In the present invention, during the process of opening the direct drinking port 111, the handle 2 and the sliding cover 13 move to the same side. During the process of closing the direct drinking port 111, the handle 2 and the sliding cover 13 also move to the same side. During the closing process, directly rotate the handle 2. When it rotates back to the initial position, the limiting piece 412 is reinserted into the limiting groove 1211 to lock the sliding cover 13 again.

[0033] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
