[0047] The second locking ring 32 has a mounting groove 323 on the top side facing the push assembly 5, and the mounting groove 323 and the threaded connection column 312 are arranged coaxially. The second locking ring 32 is coaxially provided with a positioning column 324 on the bottom wall of the mounting groove 323, and the positioning column 324 is provided with a first elastic member 35. The radial cross section of the positioning column 324 is circular, and its outer diameter is smaller than the inner diameter of the mounting groove 323. Two locking grooves 3241 are symmetrically provided at the end of the positioning column 324 along the axis.

[0048] Reference Figure 3 , Figure 4 and Figure 6 The pushing assembly 5 includes a pushing ring 51 , a pushing block 52 limitedly installed on the top of the pushing ring 51 , and a second elastic member 53 connected to the pushing block 52 .

[0049] The pushing ring 51 is disc-shaped as a whole, and its outer diameter is matched with the outer diameter of the second positioning platform 321. The distance from the bottom surface of the pushing ring 51 to the top surface of the second positioning platform 321 is the sliding range of the pushing component 5 as a whole. The bottom of the pushing ring 51 is provided with a plurality of pushing arc blocks 511 for pushing the elastic sealing ring 4 along the circumferential direction of the axis. The second positioning platform 321 has a pushing through hole 3211 corresponding to the pushing arc block 511 one by one and for the pushing arc block 511 to pass through.

[0059] The arc of the rotating through hole 63 in the horizontal direction is the rotation range of the limit ring 81. The limit ring 81 has two locking holes 812 at the bottom of the end away from the toggle block 83, and the two locking holes 812 are arranged at intervals along the axis circumferentially. The elastic plunger 82 is consistent with the spring plunger structure of the prior art, and is arranged corresponding to the locking holes 812. By rotating the toggle block 83 back and forth, the two locking holes 812 are matched with the plunger head in sequence.

[0060] The limiting ring 81 has a limiting placement groove 813 that runs through the upper and lower end surfaces and is used for the unlocking button 71. A plurality of pressing limiting portions 711 are arranged at circumferential intervals on the outer wall of the unlocking button 71. The pressing limiting portion 711 and the unlocking button 71 are integrally formed and extend in the radial direction. The limiting ring 81 is provided with a limiting locking groove 814 corresponding to the pressing limiting portion 711 in the limiting placement groove 813. The limiting locking groove 814 includes a first groove 8141 and a second groove 8142, the first groove 8141 runs through and is connected to the top of the limiting ring 81, and the axial depth of the second groove 8142 is the same as the thickness of the pressing limiting portion 711.

[0061] When one locking hole 812 of the limit ring 81 and the elastic plunger member 82 are locked, the pressing limit portion 711 and the first groove 8141 correspond. At this time, the unlocking drive member 7 is in an unlocked state and can be slid and pressed in the up and down directions. When the other locking hole 812 of the limit ring 81 and the elastic plunger member 82 are locked, the pressing limit portion 711 and the second groove 8142 correspond. At this time, the pressing limit portion 711 is limited by the second groove 8142 and cannot slide in the up and down directions, thereby reducing the situation of accidentally touching the unlocking drive member 7 under normal storage conditions and improving ease of use.

[0062] The top of the cup cap 6 also has a sealing cover 64 covering the sliding groove 62 . The sealing cover 64 and the inner wall of the sliding groove 62 are sealed and clamped to reduce the probability of external dust and other pollution sources entering into the limiting ring 81 .

[0063] Second embodiment: In this embodiment, except that a handle portion 65 is provided on the cup cap 6, the rest of the structure is consistent with that of the first embodiment.

[0064] Reference Fig. 9 and Fig.10 In order to facilitate the taking of the heat preservation, a handle portion 65 is further provided on the outer wall of the cup cap 6, and the handle portion 65 is located on the side away from the toggle block 83. The handle portion 65 is integrally provided on the side wall of the cup cap 6, and the cross section of the handle portion 65 is U-shaped. In other embodiments, the handle portion 65 is rotatably provided on the side wall of the cup cap 6.

[0065] The implementation principle of the threadless press-type sealed thermos cup according to the embodiment of the present application is as follows: when installing the cup cover 1 and the cup body 2, first adjust the positioning column 324 and the pushing block 52 to the unlocked state, then insert the cup cover 1 into the cup body 2, and the second positioning platform 321 is positioned and abutted against the open end surface of the cup body 2; push the cup cap 6 and the pushing assembly 5 downward, and through the cooperation of the first locking arc surface 5211 and the second locking arc surface 3242, the positioning column 324 passes through the locking through hole 513, and after the locking block 521 and the locking groove 3241 correspond to each other, under the action of the second elastic member 53, the locking block 521 is automatically inserted into the locking groove 3241, so that the positioning column 324 and the pushing ring 51 are locked, and the pushing arc block 511 simultaneously pushes the elastic sealing ring 4 downward, so that the elastic deformation portion 41 expands and is clamped between the first positioning platform 311 and the inner wall of the cup body 2; When unlocking is required, first rotate the toggle block 83 to drive the limit ring 81 to rotate, so as to press the limit portion 711 and the first groove 8141, and the unlocking drive member 7 is adjusted to the unlocking state; then press the unlocking drive member 7 downward so that the unlocking piece 72 passes through the unlocking through hole 621 and abuts against the unlocking block 523, and continue to press, and under the action of the first unlocking arc surface 5231 and the second unlocking arc surface 721, the locking block 521 is driven to disengage from the locking groove 3241; release the unlocking drive member 7, the cup cap 6 and the push ring 51 automatically reset upward under the action of the first elastic member 35, so as to realize the locking of the positioning column 324 and the push ring 51, and at the same time the elastic sealing ring 4 also restores its deformation, and the cup cover 1 can be removed from the cup body 2 at this time.

[0066] Exhaust principle: when the positioning column 324 and the locking block 521 are in the locked state, the sealing column 516 is inserted into the second exhaust hole 3231, and the inner cavity of the cup body 2 and the outside are in a sealed state; when the positioning column 324 and the locking block 521 are disengaged, the sealing column 516 moves upward to disengage from the second exhaust hole 3231, and the first exhaust hole 3122, the exhaust chamber 34, the second exhaust hole 3231 and the exhaust gap 3212 form an exhaust channel, which connects the inner cavity of the cup body 2 and the outside atmosphere to achieve pressure relief and exhaust.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
