Description

Technical Field

[0001] This application relates to the field of water cup lid technology, and in particular to a double-locking water cup lid that prevents accidental contact. Background Technology

[0002] To meet the drinking habits of different groups of people, existing water cups are generally equipped with a direct drinking spout or a sippy spout on the lid, allowing users to drink the water directly from the cup through the direct drinking spout.

[0003] In the existing technology, the cup lid usually includes a main lid body and a top lid. The main lid body is mainly connected to the cup body by threads. The drinking spout is set on the main lid body. The top lid is used to block the drinking spout. One end of the top lid is hinged to the main lid body, and the other end of the top lid is snapped onto the main lid body. When in use, it can be used simply by rotating to open the top lid.

[0004] However, when using a water cup with the aforementioned lid, the lid is prone to being accidentally opened by external force, causing the liquid inside the cup to spill out, which is an area that needs improvement. Utility Model Content

[0005] To address the problem that existing water cup lids are prone to accidental opening, this application provides a double-locking water cup lid to prevent accidental opening.

[0006] This application provides a double-locking anti-accidental-touch water cup lid, which adopts the following technical solution:

[0007] A double-locking anti-accidental-touch water cup lid includes a main lid body and a top cover rotatably connected to the main lid body. The main lid body has a drinking spout, and the top cover has a sealing block for blocking the drinking spout. The top cover has a first locking switch for preventing itself from rotating open and a second locking switch for preventing the first locking switch from opening.

[0008] By adopting the above technical solution, when in use, the top cover is rotated to block the drinking spout with the sealing block, and then the top cover can be locked by the first locking switch, thereby reducing the probability of the top cover being accidentally opened under external force. At the same time, the first locking switch is locked by the second locking switch, thereby reducing the possibility of the top cover being opened due to the accidental opening of the first locking switch, and thus further reducing the probability of the top cover being accidentally opened under external force.

[0009] Preferably, the first locking switch includes a plug slidably disposed on the top cover, a first lever for driving the plug to slide, a sliding rod fixed to one end of the plug, and a return spring sleeved on the sliding rod. The main cover has a groove, which is fitted into the end of the plug away from the sliding rod. One end of the first lever is detachably connected to the plug, and the other end of the first lever is slidably disposed on the top cover. A limit block is fixed on the top cover, and a through hole is formed on the limit block. The end of the sliding rod away from the plug is slidably inserted into the through hole, and the end face of the sliding rod is flush with the side wall of the limit block. One end of the return spring abuts against the end of the plug, and the other end of the return spring abuts against the limit block. The second locking switch is used to prevent the sliding rod from sliding.

[0010] By adopting the above technical solution, when the top cover is rotated and locked, the sliding rod drives the end of the insert block to be inserted into the groove under the action of the return spring. The groove limits the insertion block and achieves the locking and fixing of the top cover. When it is necessary to open the top cover, the operator only needs to move the first lever to disengage the insert block from the groove, and then the top cover can be opened. It is simple and convenient to use. At the same time, the second locking switch limits the sliding rod to prevent the second lever from being moved due to accidental contact under external force.

[0011] Preferably, a snap-fit ​​block is fixed on the insert block, and a snap-fit ​​groove for embedding the snap-fit ​​block is opened at one end of the first push block facing the insert block, and the snap-fit ​​block and the snap-fit ​​groove form an interference fit.

[0012] By adopting the above technical solution, the locking block and the locking groove cooperate to achieve a detachable connection between the insert block and the first lever block, thereby facilitating the overall assembly and use of the cup lid.

[0013] Preferably, the second locking switch includes a second lever block slidably connected to the top cover and an abutment plate fixed to one end of the second lever block. The abutment plate abuts against the side wall of the limiting block and one end of the sliding rod.

[0014] By adopting the above technical solution, during use, the second lever is moved to drive the abutment plate to slide, so that the abutment plate abuts against the end of the sliding rod, thereby limiting the first lever. This reduces the possibility of the first lever opening accidentally due to accidental contact, which could cause the top cover to open unexpectedly. When it is necessary to open the top cover, the user first moves the second lever to disengage the abutment plate from the sliding rod, and then moves the first lever to drive the insert block out of the groove, so that the top cover can be rotated and opened. The overall use is simple and convenient.

[0015] Preferably, the second lever is fixed with an anti-slip protrusion for the user to flick.

[0016] By adopting the above technical solution, the anti-slip protrusions make it easier for users to move the second lever during use.

[0017] Preferably, the second locking switch includes a third lever block slidably connected to the top cover, a linkage rod fixed to the third lever block, and a positioning protrusion fixed to the end of the linkage rod away from the third lever block. The insert block is provided with a positioning groove for embedding the positioning protrusion.

[0018] By adopting the above technical solution, when in use, the third lever is moved to drive the linkage rod to slide, thereby inserting the positioning protrusion into the positioning groove. The positioning groove and the positioning protrusion cooperate to limit the insertion of the block. When it is necessary to open the top cover, simply push the third lever in the opposite direction to disengage the positioning protrusion from the positioning groove, and then rotate to open the top cover. It is simple and convenient to use.

[0019] Preferably, the positioning protrusion has a first guide slope at one end facing the positioning groove, and the positioning groove has a second guide slope at the edge of the groove opening, with the first guide slope and the second guide slope being configured in cooperation.

[0020] By adopting the above technical solution, when in use, the cooperation of the first guide slope and the second guide slope facilitates the insertion of the positioning protrusion into the positioning groove, thereby facilitating the use of the third push block.

[0021] Preferably, a magnet assembly is provided between the top cover and the third lever, the magnet assembly being used to prevent the third lever from sliding without external force.

[0022] By adopting the above technical solution, the third lever is magnetically positioned by the magnet assembly during use, thereby reducing the possibility of the third lever accidentally sliding under external force, which is more conducive to ensuring the stability of the second locking switch in limiting the first locking switch.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By rotating the top cover, the sealing block blocks the drinking spout. Then, the top cover can be locked by the first locking switch, thereby reducing the probability of the top cover being accidentally opened under external force. At the same time, the first locking switch is locked by the second locking switch, thereby reducing the possibility of the top cover being opened due to the accidental opening of the first locking switch, and further reducing the probability of the top cover being accidentally opened under external force.

[0025] 2. Through the combined action of the insert block, sliding rod, first lever block and return spring, the top cover is automatically locked onto the main cover during the snap-fit ​​process, making it simple and convenient to use overall;

[0026] 3. By using the third lever, linkage rod, positioning protrusion and magnet assembly in combination, the stability of the second locking switch in limiting the first locking switch is further enhanced while ensuring that the top cover can be opened normally. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0034] This application discloses a double-locking anti-accidental-touch water cup lid.

[0035] Example 1:

[0036] Reference Figure 1 and Figure 2A double-locking anti-accidental-touch water cup lid includes a horizontally placed main lid body 1 and a top cover 2 disposed on the main lid body 1. The main lid body 1 has an internal thread for connecting to the body of the water cup. A direct drinking spout 11 is provided through the main lid body 1 for the user to directly drink the solution in the cup. One end of the top cover 2 is hinged to the main lid body 1, and the other end of the top cover 2 is fastened to the main lid body 1. A sealing block 3 is glued and fixed on the inner side of the top cover 2. The sealing block 3 is used to block the direct drinking spout 11. In this embodiment, the sealing block 3 is made of flexible rubber.

[0037] Reference Figure 2 and Figure 3 The top cover 2 is composed of an upper shell 21 and a bottom plate 22. The bottom plate 22 is snapped onto the bottom end face of the upper shell 21, forming an installation cavity 23 between the upper shell 21 and the bottom plate 22. A first locking switch 4 and a second locking switch 5 are provided on the bottom plate 22. In use, the top cover 2 is rotated to block the drinking spout 11 with the sealing block 3. Then, the top cover 2 is locked onto the main cover 1 by the first locking switch 4. This reduces the possibility of the top cover 2 being accidentally opened due to accidental contact. At the same time, the second locking switch 5 locks the first locking switch 4 to prevent the first locking switch 4 from being accidentally opened, thereby further ensuring the stability of the top cover 2 after it is locked.

[0038] Reference Figure 2 and Figure 3 The first locking switch 4 consists of a plug 41, a first lever 42, a sliding rod 43, and a return spring 44. One end of the plug 41 is slidably disposed in the mounting cavity 23, and the other end of the plug 41 passes through the upper housing 21 and is located outside the mounting cavity 23. A snap-fit ​​block 411 is integrally formed on the plug 41. The bottom end of the first lever 42 has a snap-fit ​​groove, and the snap-fit ​​block 411 is inserted into the snap-fit ​​groove. The snap-fit ​​block 411 is press-fitted with the inner wall of the snap-fit ​​groove. The top end of the first lever 42 passes through the upper housing 21 and is located above the upper housing 21. The first lever 42 slides on the upper housing 21 along the length of the top cover 2. In use, the snap-fit ​​block 411 and the snap-fit ​​groove work together to achieve a detachable connection between the first lever 42 and the plug 41, which facilitates the overall assembly of the cup lid.

[0039] Reference Figure 2 and Figure 3A limiting block 45 is integrally formed on the base plate 22. A through hole is provided on the limiting block 45. The sliding rod 43 and the return spring 44 are both located between the insert block 41 and the limiting block 45. One end of the sliding rod 43 is integrally formed with the insert block 41, and the other end of the sliding rod 43 is slidably inserted into the through hole. The return spring 44 is sleeved on the sliding rod 43, and one end of the return spring 44 abuts against the end of the insert block 41, and the other end of the return spring 44 abuts against the side wall of the limiting block 45. When the insert block 41, the first push block 42, the sliding rod 43 and the return spring 44 are installed in the mounting cavity 23, in the initial state of the return spring 44, the end of the sliding rod 43 away from the insert block 41 is flush with the side wall of the limiting block 45 away from the return spring 44.

[0040] Reference Figure 2 and Figure 3 In use, when the top cover 2 is in the open state, the user rotates the top cover 2 so that the top cover 2 is fastened to the main cover 1. During the fastening process of the top cover 2, the insert 41 gradually moves away from the groove 12. During this process, the return spring 44 is gradually compressed. When the insert 41 is aligned with the groove 12, under the elastic force of the return spring 44, the insert 41 is inserted into the groove 12, thereby achieving the snap-fit ​​fixation of the top cover 2. When it is necessary to open the top cover 2, the user moves the first lever 42 to drive the insert 41 to move, thereby disengaging the end of the insert 41 from the groove 12, and then the top cover 2 can be rotated to open.

[0041] Reference Figure 2 and Figure 3 When the top cover 2 is in the locked state, it is inevitable that the first lever 42 will slide due to accidental contact, thereby causing the insert 41 to disengage from the groove 12 and the top cover 2 to rotate and open. In order to reduce the probability of the above situation, the position of the first lever 42 can be positioned by the second locking switch 5, thereby further reducing the probability of the top cover 2 rotating and opening due to accidental contact.

[0042] Reference Figure 2 and Figure 3 The second locking switch 5 is composed of a second lever 51 and an abutment plate 52. The second lever 51 slides along the width direction of the top cover 2 on the upper housing 21. The abutment plate 52 is located in the mounting cavity 23. One end of the second lever 51 extends into the mounting cavity 23 and is fixed together with the abutment plate 52. The side wall of the abutment plate 52 away from the second lever 51 abuts against the side wall of the limiting block 45 and the end of the sliding rod 43. In the initial state, the abutment plate 52 blocks the through hole. At this time, the end of the sliding rod 43 away from the insert block 41 abuts against the abutment plate 52. Thus, the first lever 42 is limited by the cooperation of the abutment plate 52 and the sliding rod 43.

[0043] Reference Figure 2 and Figure 3An avoidance groove is provided on the abutment plate 52, and an anti-slip protrusion 511 is integrally formed on the second lever 51. When it is necessary to open the top cover 2, the user moves the anti-slip protrusion 511 to drive the second lever 51 to slide, thereby driving the abutment plate 52 to slide until the avoidance groove is aligned with the through hole. Then, the user moves the first lever 42 to drive the insert 41 to move. The sliding rod 43 slides through the through hole into the avoidance groove under the action of the insert 41. After that, the top cover 2 can be rotated to open. The whole process is simple and convenient.

[0044] The implementation principle of this application embodiment is as follows: In use, the main cover 1 is screwed onto the body of the water cup. When drinking water is needed, the user first moves the second lever 51 to align the relief groove on the abutment plate 52 with the through hole, thereby providing clearance space for the sliding rod 43 to slide. Then, the user moves the first lever 42 to drive the insert 41 out of the groove 12, and then the top cover 2 can be rotated to open it, exposing the drinking spout 11. When the top cover 2 needs to be closed, the user only needs to rotate the top cover 2, and the return spring 44 will spring back. Under the action of force, the end of the insert 41 is reinserted into the groove 12, thereby securing the top cover 2 onto the main cover 1. Finally, the second lever 51 is moved so that the abutment plate 52 re-seals the through hole. Thus, the abutment plate 52 abuts and limits the sliding rod 43, thereby limiting the first lever 42. This reduces the possibility of the insert 41 disengaging from the groove 12 due to accidental contact. The overall use is simple and convenient, while also ensuring the stability of the top cover 2 in the latched state.

[0045] Example 2:

[0046] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the second locking switch 5 is composed of a third toggle block 53, a linkage rod 54 and a positioning protrusion 55. The third toggle block 53 is slidably disposed on the upper housing 21 along the width direction of the top cover 2. The linkage rod 54 is located in the mounting cavity 23, and one end of the linkage rod 54 is fixedly connected to the upper housing 21. The other end of the linkage rod 54 extends to one side of the insertion block 41. The positioning protrusion 55 is integrally formed on the end of the linkage rod 54 near the insertion block 41. A positioning groove 412 is provided on the side wall of the insertion block 41, and the positioning groove 412 and the positioning protrusion 55 are fitted together.

[0047] Reference Figure 4 and Figure 5Meanwhile, a first guide slope 56 is formed at the end of the positioning protrusion 55 facing the insertion block 41, and a second guide slope 413 is formed at the edge of the groove of the positioning groove 412. The first guide slope 56 and the second guide slope 413 are parallel and cooperate with each other. In use, when the user moves the third lever 53 to drive the linkage rod 54 to move, under the guidance of the second guide slope 413 on the first guide slope 56, the positioning protrusion 55 is embedded in the positioning groove 412. Thus, through the cooperation of the positioning groove 412 and the positioning protrusion 55, the insertion block 41 is limited, thereby ensuring the stability of the insertion block 41 inserted into the slot 12, and reducing the situation where the insertion block 41 slides out of the slot due to accidental contact with the first lever 42.

[0048] Reference Figure 4 and Figure 5 To further enhance the limiting effect of the second locking switch 5 on the first locking switch 4, a magnet assembly 6 is provided between the third lever 53 and the upper housing 21. The magnet assembly 6 is used to prevent the third lever 53 from sliding without external force. In use, the magnetic attraction force of the magnet assembly 6 limits the third lever 53 to the initial position, thereby ensuring that the third lever 53 will not slide without user interference, and thus ensuring the stability of the positioning protrusion 55 embedded in the positioning groove 412.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
