As shown in FIGS. 2-5 , the cup lid assembly 1 is mainly composed of a cup lid 101 , an inner cover plate 110 and an inner lid 111 . Openings are provided on both sides of the cup cover 101 corresponding to the raised ribs 204, and locks 104 are fixed on both sides of the cup cover 101 through rotating shafts 109, which are symmetrically rotated and fixed. A gap for the lock catch 104 to rotate is provided therebetween. The bottom of the locking buckle 104 is provided with an inward claw, and the claw can pass through the opening of the cup cover 101 and engage with the lower end surface of the convex rib 204 .

A groove is provided on the top of the inner cover 111 , and a heat insulating foam 113 is arranged in the groove. An inner cover sealing ring 112 is clamped and fixed around the inner cover 110 to prevent water from flowing into the cup body 202 from the gap between the inner cover 110 and the cup cover 101 . The bottom of the inner cover 111 is open, and the inner cover 111 is provided with a steel bowl 115. The steel bowl 115 is put in from the bottom. Bowl 115 can be used to hold food. An air pressure balance check valve 114 is provided on the outer wall of the inner cover 111 to prevent the negative pressure in the cup body from opening the cup cover.

A safety lock component is provided on the inner cover 110 , and the safety lock component includes a safety lock button 102 , a safety lock rotor 103 , a safety lock spring 105 , a top shaft 106 and a top shaft spring 107 . Two jacking shaft fixing plates 125 are respectively arranged on the vertically downward side of the cup lid 101 . One end of the jacking shaft 106 abuts against the inner side of the lock buckle 104 , and the other end passes through the jacking shaft fixing plate 125 horizontally. A guide support seat 128 is provided on the inner cover plate 110 , and a slideway slidably matched with the top shaft 106 is provided on the top of the guide support seat 128 , and the top shaft 106 can slide horizontally along the top shaft fixing plate 125 and the slideway. The guiding support seat 128 is used to guide the jacking shaft 106 and at the same time play a supporting role to reduce the stress on the jacking shaft fixing plate 125 and play the role of a reinforcing rib. The top shaft 106 is radially provided with an annular slot 119, and a card 108 is arranged inside the annular slot 119, and a top shaft spring 107 is set inside the top shaft 106, and the top shaft spring 107 is elastically fixed on the card 108 and the top shaft. Between the shaft fixing plates 125.

The center of the cup cover 101 is provided with a through hole, and the through hole is provided with a plurality of evenly distributed limiting plates 122 downward along the circumferential direction. The bottom of the limiting plate 122 is provided with a limiting tooth groove 123, and a guide gap is provided between the limiting plates 122. 124. The safety lock button 102 is evenly provided with a limit block 117 in the circumferential direction, and the bottom surface is a sawtooth surface along the circumferential direction. The safety lock rotor 103 is uniformly provided with lock teeth 118 in the circumferential direction, and the top surface of the lock tooth is inclined to match the limit tooth groove 123. noodle. The safety lock button 102 is disposed in the through hole, and its limit block 117 is slidingly matched with the guide gap 124 to prevent the safety lock button 102 from slipping out of the through hole while being guided. The safety lock rotor 103 is disposed under the safety lock button 102 , and its lock teeth 118 are located in the gaps between the teeth on the serrated surface at the bottom of the safety lock button 102 .

The center of the inner cover 110 is provided with a spring fixing post 121 , the spring fixing post 121 is a hollow structure, and the center of the spring fixing post 121 is provided with a guide post 120 . The center of the safety lock rotor 103 is directed downwards to the roommate guide bushing 126, and a safety lock spring installation gap 127 is provided between the outer wall of the guide bushing 126 and the inner wall of the safety lock rotor 103, and a safety lock spring installation gap 127 is provided between the outer wall of the guide post 120 and the inner wall of the spring fixing post 121. The gap through which the guide bushing 126 passes. The guide sleeve 126 of the safety lock rotor 103 is sleeved on the guide post 120 , the upper part of the safety lock spring 105 is located in the safety lock spring installation gap 127 , and the lower part is sleeved on the spring fixing post 121 .

As shown in Figures 6 and 7, when the safety lock button 102 is pressed hard by hand, the safety lock rotor 103 compresses the safety lock spring 105 and moves downward along the guide gap 124 due to the cooperation of the safety lock button 102 with the lock tooth inclined surface of the safety lock rotor 103. Move and spin. At this time, the lock teeth 118 of the safety lock rotor 103 are inserted into the limiting tooth grooves 123, and the safety lock rotor 103 will not pop up. At this time, press and pinch the lock catches 104 on both sides, because the front end of the jacking shaft 106 is stuck on the lock teeth 118 of the safety lock rotor 103, the lock catch 104 cannot rotate, and the cup lid assembly 1 cannot be opened, which plays the role of safety lock locking. Prevents accidental opening caused by accidentally pressing the lock. When you want to open the cup lid, press the safety lock button 102 again, the safety lock button 102 pushes the safety lock rotor 103 to rotate downward, and when you let go, the safety lock rotor 103 is guided along the guide under the elastic restoring force of the safety lock spring 105 Gap 124 moves upward. The lock tooth 118 of the safety lock rotor 103 rises and breaks away from the front end of the top shaft 106, and now the lock catch 104 is pressed, and the top shaft 106 advances forward, the lock catch is rotatable, and the cup lid is opened. In this way, the safety lock button 102 is in the locked state by pressing it once, and it is in the open state by pressing it again, so as to control the non-rotatable and rotatable states of the lock catch 104 to realize the safety lock function.

The above is only a preferred example of the present invention, and the implementation of the lock and safety locking structure is not limited thereto; the shape of the cup body can be arc-shaped at the shrinkage mouth, conical or other shapes at the beveled mouth; the material of the cup body can be Stainless steel, glass, food-grade plastics, etc.; implementations with this structural principle all belong to the scope of this invention.
