Description

Technical Field

[0001] This utility model relates to the field of water cup parts, specifically a rotating locking cup lid. Background Technology

[0002] With social development and the improvement of people's living standards, there are more and more styles of water cups. In order to make drinking more convenient, water cups with direct drinking spouts are popular. However, since most water cups on the market currently have a push-pull locking mechanism, the lid is easily accidentally touched during carrying, causing the liquid in the cup to leak.

[0003] To reduce the possibility of accidental opening of the cup lid due to misoperation of the locking structure, the existing patent CN217365306U proposes a rotary locking mechanism for a push-button cup lid switch and the cup lid itself. This mechanism involves adding a rotary locking structure to the outside of the switch to lock it in place, effectively reducing the chance of accidental opening. However, in actual use, the small contact area between the rotary locking structure and the hand makes operation inconvenient. Furthermore, the small contact area between the rotary locking structure and the switch in the locked state makes the connecting parts prone to damage, leading to a failure of the locking effect. Therefore, this issue urgently needs to be addressed. Summary of the Invention

[0004] To avoid and overcome the technical problems existing in the prior art, this utility model provides a rotary locking cup lid. This utility model locks and unlocks the switch by changing the position of a rotatable limiting member. When the limiting member is in the locking zone of the mounting groove, the switch is locked, and the lid cannot be opened, reducing the possibility of accidental activation. When the limiting member is in the unlocking zone of the mounting groove, the switch can be pressed normally to unlock the lid. By using the limiting member and the mounting groove to change the state of the switch, the possibility of the lid being opened due to accidental activation is reduced, making it safer. It also better protects the switch, increases the contact area between the switch and the limiting member, effectively prevents damage to the connection between the switch and the limiting member, and improves the locking effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The device includes a cover and a switch. The cover consists of an upper cover and a lower cover. One side of the upper cover and the lower cover is a hinge side and the other side is an opening and closing side. The opening and closing side of the upper cover and / or the lower cover is provided with a mounting groove. The switch located in the mounting groove is engaged with the corresponding lower cover or upper cover through a horizontal hinge action of the hinge shaft to lock the opening and closing side in the closed state.

[0007] With the hinge axis as the boundary, the area where the snap-in end of the switch is located in the mounting groove constitutes a locking zone, and the pressing end of the switch in the mounting groove constitutes an unlocking zone. When the limiting member rotates or slides to cover the locking zone, the switch can be unlocked by operating the pressing end. When the limiting member rotates or slides to cover the unlocking zone, the pressing end is blocked, and the switch is locked. As a further embodiment of this utility model, the limiting member is an integral structure, including a rotating plate and a rotating column. The rotating column rotates and fits on the switch, and the rotating plate is located outside the switch and fits against the groove of the mounting groove.

[0008] As a further improvement of this utility model: the switch has a connecting hole, and the inner wall of the connecting hole is provided with a protrusion for generating a jerking sensation when rotating, and the rotating column passes through the connecting hole.

[0009] As a further embodiment of this utility model: a slot with a necessary hinge axis is provided on the end face of the rotating column away from the rotating plate, and the limiting member and the switch are fixed by the engagement of the slot and the protrusion.

[0010] As a further improvement of this utility model: the length of the rotating plate is greater than half the length of the switch, and the far end of the rotating plate is in contact with the mounting groove.

[0011] As a further embodiment of this utility model: the switch and the lower cover are hinged together by a connecting shaft, the connecting shaft is disposed at the mounting groove, and the axis of the connecting shaft and the center line of the connecting hole are at the same horizontal height.

[0012] As a further embodiment of this utility model: the upper cover includes a lower hook, the lower hook is located in the mounting groove, the switch includes an upper hook, and the locking of the cover is achieved by the contact between the upper hook and the lower hook.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves the change of switch state by rotating the limiting component and changing the position of different contact areas between the limiting component and the mounting groove. When the limiting component covers the locking area of ​​the mounting groove, the switch is in a locked state. Under the obstruction of the limiting component, the switch cannot be pressed or cannot reach its maximum stroke, so the upper and lower hooks cannot disengage, and the cover cannot be opened, reducing the possibility of accidental activation. When the limiting component covers the unlocking area of ​​the mounting groove, the switch can be pressed normally to reach its maximum stroke, so that the upper and lower hooks disengage, completing the unlocking of the cover. The limiting component always covers the outside of the switch. The mounting groove and the limiting component can better protect the switch from being damaged by bumps and knocks, and can also increase the contact area between the switch and the limiting component, effectively preventing damage to the connection between the switch and the limiting component, improving the locking effect, and also better preventing the cover from being opened due to accidental activation, making it safer.

[0015] 2. In this utility model, the length of the rotating plate is greater than half the length of the switch, so that the far end of the rotating plate is always in contact with the mounting groove. The supporting force provided by the mounting groove to the rotating plate can effectively reduce the force at the connection between the switch and the limiting component, thereby extending the service life of the cup lid and improving the locking effect.

[0016] 3. By placing the limiting component outside the switch, the hand can make large-area contact with the limiting component during use, making operation more convenient. The limiting component is fixed in the optimal unlocking and locking positions through the engagement of the slot and the protrusion, so as to achieve better results. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 In this embodiment of the present invention, a rotating locking cup lid includes a lid body 1 and a switch 2. The lid body 1 is composed of an upper cover 11 and a lower cover 12. One side of the upper cover 11 and the lower cover 12 is a hinge side, and the other side is an opening / closing side. The opening / closing side of the upper cover 11 and / or the lower cover 12 is provided with a mounting groove 13. The switch 2 located in the mounting groove 13 is engaged with the corresponding mating part of the lower cover 12 or the upper cover 11 through a horizontal hinge action of the hinge shaft, for locking the opening / closing side in the closed state. The locking area is formed by the area where the engaged end of the switch 2 is located in the mounting groove 13, with the hinge shaft as the boundary. The pressing end of the switch 2 located in the mounting groove 13 constitutes the unlocking area; when the limiting member 3 rotates or slides to cover the locking area, the switch 2 can be unlocked by operating the pressing end; when the limiting member 3 rotates or slides to cover the unlocking area, the pressing end is blocked and the switch 2 is locked; by changing the contact area between the limiting member 3 and the mounting groove 13, the state of the switch 2 is changed. The limiting member 3 is set on the outside of the switch 2, so that the contact area between the hand and the limiting member 3 is larger. The structure is simple, the operation is convenient, and it can also better prevent the cover from being opened due to accidental touch, making it safer.

[0027] The unlocking area of ​​the mounting groove 13 is higher than the locking area. The length of the rotating plate 31 is greater than half the length of the switch 2. The far end of the rotating plate 31 contacts the mounting groove 13. If the rotating plate 31 is in the optimal unlocking area, the rotating plate 31 is in a vertical state and completely covers the upper part of the switch 2. The protrusion 22 is located in the slot 33. When the far end of the rotating plate 31 contacts the unlocking area, the lower part of the switch 2 is pressed, causing the switch 2 to rotate along the axis of the connecting shaft. At this time, since the rotating plate 31 is in the unlocking area, the limiting member 3 rotates synchronously with the switch 2, causing the far end of the rotating plate 31 to gradually move away from the mounting groove 13. At the same time, the upper hook 21 and the lower hook 14 gradually separate. When the lower end of the switch 2 moves to the maximum position, the upper hook 21 and the lower hook 14 completely separate, causing one side of the upper cover 11 and the lower cover 12 to be released from the latch, thus completing the unlocking of the cover 1.

[0028] When the far end of the rotating plate 31 contacts the locking area, if the rotating plate 31 is in the optimal locking area, the protrusion 22 is located in the slot 33 to achieve the locking and fixing of the switch 2 and the limiting member 3. Then the rotating plate 31 is in a vertical state and completely covers the lower part of the switch 2. The switch 2 cannot be pressed at all, and the switch 2 is in the locked state. If the rotating plate 31 is not in the optimal locking area, there is a part of the lower part of the switch 2 that is not covered by the rotating plate 31. At this time, if the lower end of the switch 2 is pressed, although the switch 2 can be rotated, it cannot be rotated to the maximum distance. Therefore, the upper hook 21 and the lower hook 14 cannot be separated to unlock the cover 1, and the switch 2 is in the locked state.

[0029] The limiting component 3 is an integral structure, comprising a rotating plate 31 and a rotating column 32. The rotating column 32 is rotatably fitted onto the switch 2. The rotating plate 31 is located outside the switch 2 and fits against the groove of the mounting slot 13, so that the far end of the rotating plate 31 contacts the mounting slot 13. Rotating the rotating plate 31 causes the rotating column 32 to rotate along the same axis, so that the far end of the rotating plate 31 is located in different areas of the mounting slot 13, thereby changing the state of the switch 2. At the same time, the mounting slot 13 can provide support for the rotating plate 31 to reduce the force at the connection between the limiting component 3 and the switch 2, reduce the possibility of damage to the connection structure, and extend the service life of the switch 2 and the limiting component 3. The rotating plate 31 is located outside the switch 2, which can increase the contact area between the hand and the limiting component 3, and also protect the switch 2 from external damage, thus extending its service life.

[0030] The switch 2 has a connecting hole 21, and the inner wall of the connecting hole 21 is provided with a protrusion 22 to produce a jerking sensation when rotated. The jerking sensation allows the user to clearly understand the state of the cup lid. The rotating column 32 passes through the connecting hole 21, and the inner wall of the connecting hole 21 is provided with the protrusion 22. The end face of the rotating column 32 away from the rotating plate 31 has a slot 33. The limiting member 3 and the switch 2 are fixed by the engagement of the slot 33 and the protrusion 22. The end face of the protrusion 22 has an arc-shaped structure. When rotated... When the moving limiter 3 is activated, the protrusion 22 can disengage from the slot 33 with a small force, allowing the limiter 3 to rotate. When the limiter 3 rotates 180° to the optimal unlocking or locking area, the protrusion 22 re-enters the slot 33 and engages with the slot 33 to fix the limiter 3. The click sensation allows people to intuitively understand whether the limiter 3 has reached the fixed position. Once the fixed position is reached, it can also prevent the position of the limiter 3 from changing due to accidental touch, thus improving the safety performance of the cup lid.

[0031] Switch 2 and lower cover 12 are hinged by a connecting shaft. The connecting shaft is located in the mounting groove 13. The axis of the connecting shaft and the center line of the connecting hole 21 are at the same horizontal level. There is a certain distance between the connecting shaft and the connecting hole 21 to ensure sufficient space for the switch 2 to be pressed and to prevent interference between the connecting shaft and the rotating column 32, which would prevent the switch 2 from being pressed to the maximum position. The upper cover 11 includes a lower hook 14 located in the mounting groove 13. Switch 2 includes an upper hook 23 located at the upper part of the switch 2. The contact between the upper hook 23 and the lower hook 14 locks the cover 1. It should be noted that the connection between the switch 2 and the cover 1, the engagement of the upper hook 23 and the lower hook 14, and the setting of the connecting shaft are all existing technologies and are not improvements of this solution. Therefore, they are omitted and will not be described in detail. At the same time, to make the structure of the cup lid more intuitive, the connecting shaft is omitted in the attached drawings of the instruction manual, but this does not affect the understanding of the solution. The actual solution has a connecting shaft.

[0032] The working principle of this utility model is as follows: When this utility model is used, the rotating plate 31 is rotated by rotation. When the far end of the rotating plate 31 contacts the unlocking area of ​​the mounting groove 13, the switch 2 is in the unlocked state. Pressing the switch 2 causes the switch 2 to rotate around the connecting shaft. In this state, the lower end of the switch 2 can move to the maximum distance, so that the upper hook 23 set on the upper end of the switch 2 can disengage from the lower hook 14, and the cover 1 can be opened. When the far end of the rotating plate 31 contacts the locking area of ​​the mounting groove 13, the switch 2 is in the locked state. In this state, pressing the switch 2, due to the interference between the rotating plate 31 and the mounting groove 13, prevents the lower end of the switch 2 from being pressed or from moving to the maximum distance, so that the upper hook 21 and the lower hook 14 cannot be separated, thereby locking the cover 1.
