Description

Technical Field

[0001] This utility model relates to the field of cup lid technology, specifically to a cup lid with a clutch structure. Background Technology

[0002] Water cups are one of the most frequently used items in people's daily lives. Especially when going out, most users carry water cups for convenient drinking.

[0003] Currently, for sealing purposes, water cups are fitted with a lid connected to the rim via threads, which serves to seal the cup and maintain its temperature. Because the lid is threaded onto the rim, it can sometimes be rotated and become loose. This can cause the cup to open accidentally, leading to liquid leakage and compromising its insulation performance.

[0004] Therefore, there is an urgent need for a technology to solve the above-mentioned technical problems. Utility Model Content

[0005] One objective of this utility model is to provide a cup lid with a clutch structure to solve the above-mentioned technical problems. The utility model adopts the following technical solution: A cup lid with a clutch structure includes a bottom cover threaded to the mouth of the cup and a movable cover rotatably connected to the end face of the bottom cover. A clutch structure is provided between the movable cover and the bottom cover. This clutch structure allows the movable cover to be in a linked or non-linked state when rotating on the bottom cover in two directions. When the movable cover twists in the direction of the bottom cover's thread, it is in a linked state, causing the movable cover to drive the bottom cover to move and rotate. When the movable cover twists in the opposite direction of the bottom cover's thread, it is in a non-linked state, causing the movable cover to rotate along the bottom cover.

[0006] Furthermore, the clutch structure includes: The ratchet portion includes a plurality of ratchet teeth arranged at equal intervals; One-way tooth, which meshes with the ratchet; A first elastic element abuts against the one-way tooth, causing the ratchet portion to extend elastically toward the ratchet portion.

[0007] Furthermore, one end of the movable cover is provided with a cavity that houses the bottom cover, so that the movable cover covers the bottom cover.

[0008] Furthermore, a locking structure is provided between the movable cover and the bottom cover. The locking structure is used to lock the movable cover onto the bottom cover, so that in the non-linkage state, twisting the movable cover causes the movable cover to drive the bottom cover to rotate together, and the direction of rotation is opposite to the direction of the thread of the bottom cover.

[0009] Furthermore, the locking structure includes a positioning post movably connected to the bottom cover, and the bottom cover is also provided with a second elastic member that abuts against the positioning post and causes the positioning post to elastically extend toward the movable cover. The locking structure also includes a positioning hole formed on the movable cover, and the positioning post elastically extends and enters the positioning hole to lock the movable cover and the bottom cover together.

[0010] Furthermore, the movable cover is also equipped with a release structure for pressing down the positioning pin to disengage it from the positioning hole. The release structure allows the movable cover to rotate along the bottom cover in the non-interlocking state. The release structure includes a push rod and a drive device that drives the push rod to enter or exit the positioning hole.

[0011] Furthermore, a spout communicating with the cup opening is formed on the bottom cover, and a window is provided on the movable cover for the spout to be exposed. A top cover is hinged to the movable cover. The top cover flips towards the movable cover and snaps onto the movable cover, thus closing the water outlet. The top rod is formed on the top cover, and the top cover constitutes a driving device that moves the top rod.

[0012] Furthermore, the push rod is movably connected to the positioning post within the positioning hole, and the driving device is disposed within the movable cover. The driving device consists of a motor, which drives the push rod to reciprocate along the axial direction of the positioning hole to push out the positioning post inserted into the positioning hole.

[0013] Furthermore, a mounting cavity is formed on the bottom cover, the one-way tooth is movably disposed within the mounting cavity, and the first elastic member is positioned between the bottom of the mounting cavity and the one-way tooth to provide an elastic thrust toward the movable cover. The ratchet portion is formed on the movable cover.

[0014] Furthermore, the positioning post is movably disposed within the mounting cavity, and the second elastic member is disposed between the bottom of the mounting cavity and the positioning post to provide an elastic thrust toward the movable cover.

[0015] The beneficial effects of this utility model are as follows: This technical solution provides a cup lid with a clutch structure. After the cup lid is threaded onto the mouth of the cup, it can seal the cup. At the same time, the clutch structure in this technical solution can restrict the movable lid from rotating on the bottom lid along the direction of the bottom lid's thread, allowing it to rotate only in the opposite direction. When the movable lid is turned along the direction of the bottom lid's thread, the clutch structure allows the movable lid to rotate along with the bottom lid, thereby further tightening the bottom lid at the mouth of the cup, thus improving the tightness of the connection between the cup lid and the cup body. When the movable lid is rotated in the opposite direction of the bottom lid's thread, this direction is also the direction of rotation that separates the bottom lid from the cup body. At this time, the movable lid can move freely on the bottom lid under the action of the clutch structure, thereby preventing the bottom lid from being rotated and loosened, and achieving the effect of preventing accidental opening. At the same time, when it is necessary to remove the lid from the cup body, the locking mechanism is triggered, which restricts the movable lid to the bottom lid. Thus, when the movable lid is turned, the bottom lid can be rotated together, and the bottom lid can be rotated at the mouth of the cup to unscrew the cup, thereby opening the water cup.

[0016] This technical solution ensures that the bottom cover screwed onto the cup opening will not loosen when the movable lid is rotated, thus preventing the lid from being accidentally opened or loosened, and ensuring the sealing and heat preservation performance of the cup.

Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0023] This technical solution provides a cup lid with a clutch structure. After the cup lid is threaded onto the mouth of a water cup, it can seal the water cup. At the same time, the clutch structure in this technical solution allows the movable lid and the bottom lid to be in a linked state and a non-linked state in two directions. In the linked state, twisting the movable lid will cause the bottom lid to rotate together, thus tightening the bottom lid at the mouth of the water cup. In the non-linked state, twisting the movable lid will allow the movable lid to rotate freely along the bottom lid, thus preventing the bottom lid from loosening at the mouth of the cup. In this case, this technical solution can prevent the cup lid from loosening and avoid the liquid inside the cup from spilling.

[0024] Specifically, in this embodiment, such as Figure 1-4 As shown, a cup lid with a clutch structure includes a bottom cover threadedly connected to the mouth of the cup, and a movable cover. The movable cover is rotatably connected to the end face of the bottom cover, and a clutch structure is provided between the movable cover and the bottom cover. The clutch structure allows the movable cover to be in a linked state or a non-linked state when rotating on the bottom cover in two directions. When the movable cover is twisted in the direction of the thread of the bottom cover, it is in a linked state, causing the movable cover to drive the bottom cover to move and rotate; when the movable cover is twisted in the opposite direction of the thread of the bottom cover, it is in a non-linked state, causing the movable cover to rotate along the bottom cover.

[0025] During use, when the movable lid is twisted in the same direction as the bottom lid's thread, the movable lid is engaged under the action of the clutch mechanism, moving the bottom lid in the same direction to tighten it onto the cup's rim, thus improving the seal between the bottom lid and the rim. When the movable lid rotates in the opposite direction to the bottom lid's thread, it is disengaged under the action of the clutch mechanism. In this case, the movable lid spins freely on top of the bottom lid, preventing it from rotating and thus preventing the bottom lid from loosening on the rim, effectively preventing liquid leakage from the cup.

[0026] In this embodiment, the clutch structure includes a ratchet portion 210, one-way teeth 212, and a first elastic member. The ratchet portion 210 includes a plurality of equally spaced ratchet teeth 211; the one-way teeth 212 mesh with the ratchet teeth 211; the first elastic member abuts against the one-way teeth 212, causing the ratchet portion to elastically extend towards the ratchet portion 210. At this time, under the action of the clutch structure, the movable cover 200 is restricted from rotating in the direction of the thread of the bottom cover 100, and can only rotate in the direction opposite to the thread of the bottom cover 100. That is, when the user holds the movable cover 200... When the bottom cover 100 is rotated in the same direction as the thread of the bottom cover 100, it can also rotate the bottom cover 100. At this time, because the rotation direction is the same as the thread direction of the bottom cover 100, the bottom cover 100 is tightened to the mouth of the cup, and the airtightness between the bottom cover 100 and the mouth of the cup is improved. When the movable cover 200 rotates in the opposite direction to the thread direction of the bottom cover 100, under the restraint, the movable cover 200 has the freedom to rotate in that direction, so that the bottom cover 100 will not be loosened, thus ensuring the airtightness between the cup cover and the cup body and preventing loosening.

[0027] In this embodiment, in order to further improve the protective performance and prevent direct operation of the bottom cover 100, as follows: Figure 2-3 As shown, one end of the movable cover 200 is provided with a cavity 203 that houses the bottom cover 100, so that the movable cover 200 covers the bottom cover 100.

[0028] During use, the bottom cover 100 is housed within the chamber 121, and the bottom cover 100 is rotatably connected to the movable cover 200. Thus, after the bottom cover 100 is threaded onto the cup opening, the user can only operate the movable cover 200 directly, without operating the bottom cover 100, thereby improving the effect of preventing accidental opening.

[0029] In this embodiment, a flange 101 is formed on the circumferential surface of one end of the bottom cover 100, and an external thread is formed on the circumferential surface of the other end of the bottom cover 100 to be threaded to the mouth of the cup. At the same time, a plurality of locking blocks 202 are formed on the inner wall surface of the chamber 121 of the movable cover 200 at equal angular intervals. When the movable cover 200 is fastened onto the bottom cover 100 and the flange 101 is housed in the chamber 121, the flange 101 and the locking blocks 202 engage with each other, thereby restricting the flange 101 within the chamber 121 and allowing the bottom cover 100 to rotate within the chamber 121. It is worth noting that the rotation direction of the bottom cover 100 within the chamber 121 can only be in the opposite direction to the thread rotation direction of the bottom cover 100 under the action of the clutch structure.

[0030] In this embodiment, when it is necessary to remove the cup lid from the cup opening, a locking structure is provided between the movable lid and the bottom lid. The locking structure is used to lock the movable lid onto the bottom lid, so that in the non-linkage state, twisting the movable lid causes the movable lid to drive the bottom lid to rotate together, and the direction of rotation is opposite to the direction of the bottom lid's thread.

[0031] In other words, when it is necessary to remove the cup lid from the rim of the cup, the locking mechanism is triggered to lock the movable lid and the bottom lid together, thereby preventing the movable lid from spinning freely when not in a linked state. At this time, when the movable lid is turned in the opposite direction of the bottom lid thread, the bottom lid can be rotated together, thereby separating the bottom lid from the rim of the cup and removing the cup lid from the rim.

[0032] In this embodiment, the locking structure is used to lock the movable cover 200 onto the bottom cover 100, thereby restricting the movable cover 200 from rotating in the opposite direction to the thread of the bottom cover 100. When it is necessary to open the cup, the movable cover 200 is operated to drive the bottom cover 100 to rotate, so that the bottom cover 100 is released at the mouth of the cup and thus separates from the cup body.

[0033] In this embodiment, as Figure 2-4 As shown, the locking structure includes a positioning post 110 movably connected to the bottom cover 100, and a second elastic member is provided on the bottom cover 100 to abut against the positioning post 110 and cause the positioning post 110 to elastically extend toward the movable cover 200. The locking structure also includes a positioning hole 201 formed on the movable cover 200. The positioning post 110 elastically extends and enters the positioning hole 201 to lock the movable cover 200 and the bottom cover 100 together.

[0034] In other words, when the positioning post 110 extends toward the movable cover 200 under the elastic thrust of the second elastic element, the positioning post 110 passes into the positioning hole 201, thereby locking the movable cover 200 and the bottom cover 100. This allows the bottom cover 100 to rotate when the movable cover 200 is rotated, making it convenient to rotate and remove the bottom cover 100 from the cup body.

[0035] During the use of this cup lid, when the movable lid rotates for one full turn or nearly one full turn, the positioning pin will inevitably be pushed into the positioning hole by the second elastic element. This will result in the movable lid rotating for a maximum of one more full turn, which will affect the performance of this structure. In order to further improve the performance of preventing the cup lid from opening accidentally, a release structure is provided in this embodiment to push the positioning pin to disengage it from the positioning hole, thereby ensuring that the movable lid can continue to rotate along the bottom cover when not in linkage. In this embodiment, the release structure includes a push rod and a drive device that drives the push rod to enter or exit the positioning hole.

[0036] During use, the drive device drives the push rod to enter the positioning hole, thereby contacting the positioning post and causing the positioning post to overcome the elastic thrust of the second elastic element and exit within the positioning hole, thereby releasing the positioning post from locking the movable cover, allowing the movable cover to rotate freely along the bottom cover in a non-linked state.

[0037] In this embodiment, a spout 130 communicating with the cup opening is formed on the bottom cover 100, and a window 220 is provided on the movable cover 200 for the spout 130 to be exposed; an upper cover 300 is hinged on the movable cover 200, and the upper cover 300 is flipped toward the movable cover 200 and snapped onto the movable cover 200 to close the spout 130. A push rod 310 corresponding to the positioning hole 201 is formed on the upper cover 300. After the upper cover 300 is closed on the movable cover 200, the push rod 310 inserts into the positioning hole 201 and pushes the positioning pin out of the positioning hole 201. In this embodiment, the upper cover is defined as a driving device that drives the push rod to insert or withdraw from the positioning hole. It can be understood that in this embodiment, the positioning hole is perforated, so that the positioning pin and the push rod can respectively insert into the positioning hole at both ends of the positioning hole.

[0038] After the upper cover 300 is fastened onto the movable cover 200 and they are interlocked, the push rod 310 inserts into the positioning hole 201 and pushes the positioning pin 110 out of the positioning hole 201. At this time, the positioning pin 110 releases its locking effect on the movable cover 200, allowing the movable cover 200 to drive the upper cover 300 to rotate in the opposite direction to the thread of the bottom cover 100 under the action of the clutch mechanism. At this time, if the rotatable movable cover 200 is accidentally rotated, it will not drive the bottom cover 100 to rotate, thereby preventing the bottom cover 100 from being opened and further improving the anti-accidental opening effect. Therefore, when it is necessary to remove the bottom cover 100 from the cup body, the top cover 300 is opened on the movable cover 200. At this time, the push rod 310 disengages from the positioning hole 201, which means it releases the contact with the positioning post 110. When the movable cover 200 is rotated so that the positioning hole 201 moves to the position corresponding to the positioning post 110, the positioning post 110 can extend into the positioning hole 201 under the action of the second elastic element, thereby locking the movable cover 200 onto the bottom cover 100. At this time, the bottom cover 100 can be rotated by operating the movable cover 200, and the bottom cover 100 can be removed from the cup body. In this embodiment, it is conceivable that the snap-fit ​​between the movable cover 200 and the top cover 300 can be implemented using a snap-fit ​​structure in the prior art, as long as the snap-fit ​​connection and the ability to separate can be achieved. The specific structure is not limited in this embodiment.

[0039] In this embodiment, the one-way tooth 212 is disposed on the bottom cover 100, and the ratchet portion 210 is formed on the movable cover 200. Specifically, a mounting cavity 120 is formed on the bottom cover 100, the one-way tooth 212 is movably disposed within the mounting cavity 120, and a first elastic member is positioned between the bottom of the mounting cavity 120 and the one-way tooth 212 to provide an elastic thrust toward the movable cover 200; the ratchet portion 210 is formed on the movable cover 200. Under the action of the first elastic member, the one-way tooth 212 elastically extends toward the movable cover 200, thereby enabling the tooth surface of the one-way tooth 212 to mesh with the ratchet 211, achieving a one-way rotation effect. It is conceivable that the ratchet 211 has a tooth surface inclined to one side, and the one-way tooth 212 is simultaneously provided with a tooth surface that is adapted to the ratchet 211 and is also inclined, so that when the one-way tooth 212 and the ratchet 211 mesh with each other, the movable cover 200 can achieve one-way rotation.

[0040] Meanwhile, the positioning post 110 is movably disposed within the mounting cavity 120, and the second elastic member is disposed between the bottom of the mounting cavity 120 and the positioning post 110 to provide an elastic thrust toward the movable cover 200.

[0041] Furthermore, in this embodiment, the mounting cavity 120 includes two independent chambers 121, with the one-way tooth 212 and the positioning post 110 respectively disposed within the chambers 121.

[0042] like Figure 2 As shown, the two chambers 121 are set independently of each other. The one-way tooth 212 and the positioning post 110 are respectively movably set in the chamber 121. The cover plate 122 closes the opening of the chamber 121 by means of screw connection, thereby restricting the one-way tooth 212 and the positioning post 110 in the chamber 121 and preventing them from being pushed out in the chamber 121 under the elastic thrust of the elastic element.

[0043] Example 2

[0044] In this embodiment, the main structure of the inner cover is the same as that in Embodiment 1, except that the specific structure of the release structure is changed. Specifically, the push rod and the driving device are both set on the movable cover. Specifically, a chamber is provided inside the movable cover, and the positioning hole is set on the side wall of the chamber. The push rod is movably connected in the positioning hole, and the driving device is set in the chamber. In this embodiment, the driving device is composed of a motor, and the motor is connected to the push rod for transmission, so as to drive the push rod to move back and forth along the axial direction of the positioning hole, thereby pushing out the positioning pin that elastically extends into the positioning hole.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
