Description
Technical Field
[0001] The utility model relates to the technical field of water cups, in particular to a safety locking structure for a flip-cover water cup. Background Art
[0002] Water cups are common daily necessities. In addition to using them at home, many people also have the habit of carrying water with them when going out. In this scenario, flip-top water cups are common. The upper part of the cup lid can be opened independently, and the lower part is threadedly connected to the cup body. However, the problem is that the threaded connection cannot guarantee long-term stability. It may become loose when carried in a bag, and looseness may cause water to enter the bag or even damage the items in the bag. Therefore, the locking security is insufficient. Based on this situation, how to improve the security of the flip-top water cup locking is becoming an increasingly urgent problem that relevant technical personnel need to solve. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a safety locking structure for a flip-top water cup.

[0005] Furthermore, a guide hole is provided through the upper portion of the lower outer cover, the upper portion of the pressure-bearing column is slidably plugged into the guide hole, and a limiting plate is provided at the lower portion of the pressure-bearing column, and the diameter of the limiting plate is larger than the diameter of the guide hole.
[0006] Furthermore, a spring is provided inside the lower outer cover, the spring is located above the clamping column, two ends of the spring are fixedly connected to the lower outer cover and the rotator respectively, and the spring is in a compressed state.
[0007] Furthermore, the lower outer cover is provided with blocks in an annular array inside, and an annular groove is provided on the periphery of the lower inner cover, and the blocks are slidably engaged with the annular groove.
[0008] Furthermore, a rotating seat is provided at the rear of the upper cover, a fixed seat is provided at the rear of the lower outer cover, an external torsion spring is provided between the rotating seat and the fixed seat, and a card slot is provided at the front of the water outlet.
[0009] The beneficial effects of the safety locking structure for a flip-top water cup of the utility model are:
[0010] The rotator is rotatably sleeved with the fixed shaft, the pressure-bearing column is slidably plugged into the guide hole, and the spring is fixedly connected to the rotator in a compressed state, so that the pressure-bearing column is pressed down when the upper cover is closed and is lifted when the upper cover is opened. Accordingly, the clamping column and the clamping hole do not contact when the upper cover is closed and are plugged into when the upper cover is opened. Therefore, when the upper cover is closed, twisting the lower outer cover can only cause it to rotate idly, and when the upper cover is opened, twisting the lower outer cover can synchronously twist the lower inner cover. Therefore, unless the upper cover is actively opened, the lower inner cover will not be twisted, which effectively ensures a long-term and stable connection between the lower inner cover and the matching cup body, thereby effectively improving the safety of locking the flip-top water cup.

DETAILED DESCRIPTION
[0018] To make the description clearer, a safety locking structure for a flip-top water cup of the present invention is further described in conjunction with the accompanying drawings.
[0019] Example 1
[0020] A safety locking structure for a flip-top water cup comprises an upper cover 4 and a lower outer cover 3, characterized in that a lower inner cover 7 is arranged inside the lower outer cover 3, a locking hole 5 is arranged in a ring array on the upper part of the lower inner cover 7, a thread is arranged on the lower part of the lower inner cover 7, a middle cover 8 is fixedly arranged at the center position inside the lower outer cover 3, a water outlet 18 is arranged on the upper part of the middle cover 8, a fixed shaft 16 is fixedly arranged at the rear part of the middle cover 8, a rotator 15 is arranged at the rear of the middle cover 8, the middle position of the rotator 15 is rotatably sleeved with the fixed shaft 16, a locking column 17 is fixedly arranged at one end of the rotator 15, the locking column 17 is located above the locking hole 5, a pressure-bearing column 10 is arranged above the other end of the rotator 15, and the lower part of the pressure-bearing column 10 contacts the rotator 15.
[0021] Furthermore, a guide hole 13 is provided through the upper portion of the lower outer cover 3 , the upper portion of the pressure-bearing column 10 is slidably plugged into the guide hole 13 , and a limiting plate 12 is provided at the lower portion of the pressure-bearing column 10 , the diameter of the limiting plate 12 being larger than the diameter of the guide hole 13 .
[0022] Furthermore, a spring is provided inside the lower outer cover 3 , and the spring is located above the clamping column 17 . Both ends of the spring are fixedly connected to the lower outer cover 3 and the rotator 15 , respectively, and the spring is in a compressed state.
[0023] Furthermore, the lower outer cover 3 is provided with blocks 11 in an annular array inside, and the lower inner cover 7 is provided with an annular groove 6 on its periphery, and the blocks 11 are slidably engaged with the annular groove 6 .
[0024] Furthermore, a rotating seat 1 is provided at the rear of the upper cover 4 , a fixed seat 2 is provided at the rear of the lower outer cover 3 , an external torsion spring 14 is provided between the rotating seat 1 and the fixed seat 2 , and a card slot 9 is provided at the front of the water outlet 18 .
[0025] Example 2
[0026] The spring in Example 1 and its connection with the lower outer cover 3 and the rotator 15 can be replaced with the following technical features:
[0027] Furthermore, an internal torsion spring is provided between the rotator 15 and the fixed shaft 16 .
[0028] The working principle of the safety locking structure for a flip-top water cup of the present invention is as follows: Taking Example 1 as an example, in the initial state, the lower inner cover 7 is screwed onto the upper part of the matching cup body through a thread, the upper cover 4 is closed, buckled on the lower outer cover 3 and engaged with the card slot 9, and at the same time, the upper cover 4 presses down the pressure-bearing column 10, and then the pressure-bearing column 10 presses down the rotator 15, so that the rotator 15 maintains balance, and the card column 17 stops above the card hole 5. At this time, even if there is an external force to twist the lower outer cover 3, it can only make the lower outer cover 3 and the card block 11 rotate idly along the annular groove 6, and the lower inner cover 7 will not be separated from the cup body. If the user actively The upper cover 4 is automatically released from the engagement with the card slot 9, and the external torsion spring 14 directly pops open the upper cover 4, and water can be drunk through the water outlet 18. At the same time, the upper cover 4 no longer presses down the pressure column 10, the spring is released and the card column 17 pops down, so that the card column 17 is engaged with the card hole 5. Accordingly, the pressure column 10 moves up until the limit plate 12 touches the lower outer cover 3, and the card column 17 is engaged with the card hole 5, so that at this time, the lower inner cover 7 can be separated from the cup body by twisting the lower outer cover 3, and subsequent operations can be performed, such as adding water. After the operation is completed, the lower outer cover 3 and the lower inner cover 7 are twisted to reset, and the upper cover 4 is pressed to reset.
[0029] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
