Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a quick-opening water cup. Background Art

[0002] A water cup is a special container for holding water, generally with a small volume.

[0003] To achieve the heat preservation and dust prevention effects of the water cup, a cup cover is often provided at the open end of the cup body. In addition, to further facilitate the outdoor carrying of the water cup, the cup cover and the open end of the cup body often adopt a sealed and fixed form. As recorded in the text named "A Water Cup" with the Chinese patent publication number CN219680277U, the cup cover and the cup body adopt a threaded screwing sealed and fixed form. Although this type of threaded screwing connection method can achieve a good sealing effect, in actual use, it is necessary to rotate the cup cover vigorously to open and close the cup cover, resulting in the problem of inconvenient opening and closing. Especially when hot water is loaded in the cup body, as the temperature of the hot water decreases, the pressure in the cup body gradually decreases, causing a negative pressure adsorption force on the cup cover by the cup body. This negative pressure adsorption force increases the friction between the threaded threads that engage the cup cover and the cup body, making it more difficult to open the cup cover, and thus urgently needs to be solved. Content of the Utility Model

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a quick-opening water cup, in which the opening and closing process of the cup cover is labor-saving, significantly improving the convenience of opening and closing the cup cover.

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

[0006] A quick-opening water cup includes a main cup body and a cup cover. The cup cover has a protrusion that can be inserted into the inner cavity of the cup mouth of the main cup body, and a sealing fit is formed by the outer edge of the bottom of the protrusion and the inner cavity of the main cup body; a slot is provided on the inner wall of the cup mouth of the main cup body, and a locking plug block that can slide radially along the main cup body and can form a plugging and locking fit with the slot is provided on the side wall of the protrusion; an opening and closing plug rod that can slide axially along the main cup body is provided on the top of the cup cover, and the lower rod section of the opening and closing plug rod is provided with a wedge block that can form an inclined wedge fit with the locking plug block.

[0007] As a further solution of the present utility model: The middle rod section of the opening and closing insertion rod is set as a guiding slide rod that is slidably matched with the cup cover and penetrates above the cup cover. The upper rod section of the opening and closing insertion rod is set as a locking rotating head that is rotationally matched with the penetrating section of the guiding slide rod through a horizontal rotating shaft. The locking rotating head is used to lock the limit position of the downward sliding of the guiding slide rod. The outer edge of the locking rotating head has two locking surfaces with different distances from the horizontal rotating shaft. When the locking rotating head rotates to the locking state and the unlocking state where the two locking surfaces are respectively in contact with the top of the cup cover, the wedge-shaped block is respectively at the locking height where the locking insertion block is inserted into the slot and the unlocking height where the locking insertion block is separated from the slot.

[0008] As a further solution of the present utility model: The wedge-shaped block has a wedge-shaped surface structure with a narrow upper part and a wide lower part, and this wedge-shaped surface is a flat smooth surface structure. A return spring for driving the separation of the locking insertion block from the slot is arranged on the protruding part.

[0009] As a further solution of the present utility model: The wedge-shaped block has a wedge-shaped surface structure with a narrow upper part and a wide lower part, and a dovetail groove is arranged on the wedge-shaped surface of the wedge-shaped block. The groove length direction of the dovetail groove is distributed along the wedge-shaped surface direction. The inner end of the locking insertion block is set as a dovetail block that forms a wedge-shaped fit with the cavity of the dovetail groove.

[0010] As a further solution of the present utility model: An inner groove is arranged on the outer edge of the locking rotating head. The penetrating section of the guiding slide rod forms a rotational fit with the groove wall of the inner groove. Elastic deformable convex strips are fixed on the groove wall of the inner groove. A blocking groove for accommodating the convex strips is arranged on the penetrating section of the guiding slide rod. When the locking rotating head is in the locking state, the convex strips are located inside the blocking groove.

[0011] As a further solution of the present utility model: The protruding part has a cylindrical structure with a hollow interior. The opening and closing insertion rod and the cup cover are coaxially distributed. The locking insertion blocks are set to be at least two and are circumferentially evenly distributed around the opening and closing insertion rod.

[0012] As a further solution of the present utility model: The slot is an annular structure that is coaxially distributed with the main cup body.

When opening and closing the cup lid, by sliding the opening and closing insertion rod along the axial direction of the main cup body and utilizing the wedge-shaped fit between the wedge-shaped block and the locking insertion block, the locking insertion block can be driven to separate from and be inserted into and locked with the slot. During the process of opening the cup lid, there is no need to rotate the cup lid. When there is a large negative pressure in the inner cavity of the main cup body, after the cup lid is unlocked, just swing the cup lid to make the inner cavity of the main cup body communicate with the external atmosphere, and then the cup lid can be quickly removed. This makes the process of opening and closing the cup lid labor-saving and significantly improves the convenience of opening and closing the cup lid.

[0017] 2. By adopting the method of rotating the locking head to realize the locking and unlocking of the cup lid, the convenience of opening and closing the cup lid is further improved.

[0018] 3. Between the locking head and the guiding slide rod, there are mutually cooperating convex strips and blocking grooves, which increase the resistance for the locking head to switch from the locked state to the unlocked state and prevent the locking head from being accidentally touched and opened.

[0019] 4. The main cup body includes a lower cup body and an upper ring body threadedly connected to the opening end of the lower cup body. The upper ring body forms the cup mouth of the main cup body. This layout enables the main cup body to have two opening methods: unscrewing the upper ring body or unlocking and opening the cup lid, making the opening methods of the main cup body more diverse.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] For the sake of understanding, the specific structure and working mode of the present utility model are further described as follows in conjunction with the attached drawings:

[0027] The specific structure of the present utility model is referred to Figures 1-4 As shown, its main structure includes a main cup body 10 and a cup cover 20. Among them, the cup cover 20 has a protrusion that can be inserted into the inner cavity of the cup mouth of the main cup body 10. A sealing fit is formed between the bottom outer edge of the protrusion and the inner cavity of the main cup body 10, ensuring the sealing performance between the cup cover 20 and the main cup body 10. In addition, above the location where the above-mentioned sealing fit is formed, a slot 111 is provided on the inner wall of the cup mouth of the main cup body 10, and a locking plug 21 that can slide radially along the main cup body 10 and can form a plugging and locking fit with the slot 111 is provided on the side wall of the protrusion. By inserting or separating the locking plug 21 from the slot 111, the locking and unlocking between the main cup body 10 and the cup cover 20 can be achieved. An opening and closing plug rod 22 that can slide axially along the main cup body 10 is provided at the top of the cup cover 20, and a wedge block 221 that can form an inclined wedge fit with the locking plug 21 is provided on the lower rod section of the opening and closing plug rod 22. When the cup cover 20 is opened and closed, by sliding the opening and closing plug rod 22 axially along the main cup body 10 and using the wedge fit between the wedge block 221 and the locking plug 21, the locking plug 21 can be driven to separate from and plug and lock with the slot 111. During the opening process of the cup cover 20, there is no need to rotate the cup cover 20. When there is a large negative pressure in the inner cavity of the main cup body 10, after unlocking the cup cover 20, just swing the cup cover 20 to make the inner cavity of the main cup body 10 communicate with the external atmosphere, and the cup cover 20 can be quickly removed, making the opening and closing process of the cup cover 20 labor-saving and significantly improving the convenience of opening and closing the cup cover.

[0028] On the above basis, as Figure 1 shown, the middle rod section of the opening and closing plug rod 22 is set as a guiding slide rod 222 that is slidably matched with the cup cover 20 and penetrates above the cup cover 20 to ensure the stability of the vertical sliding of the opening and closing plug rod 22. The upper rod section of the opening and closing plug rod 22 is set as a locking rotating head 223 that is rotationally matched with the penetrating section of the guiding slide rod 222 through a horizontal rotating shaft. The locking rotating head 223 is used to lock the limit position of the downward sliding of the guiding slide rod 222. Specifically, the outer edge of the locking rotating head 223 has two locking surfaces with different distances from the horizontal rotating shaft. As the locking rotating head 223 rotates and the two locking surfaces face downward respectively, when the two locking surfaces are respectively attached to the top of the cup cover 20, the locking rotating head 223 is in the locking state as shown in Figure 1 and as shown in Figure 3The unlocked state shown; obviously, the vertical height of the lower end of the opening and closing plug rod 22 will change in the locked state and the unlocked state, that is, the wedge block 221 will be adjusted to the locked height and the unlocked height. Since the wedge block 221 is in wedge-shaped fit with the locking plug 21 during the up and down sliding process, the locking plug 21 is inserted into and separated from the slot 111, so as to realize the locking and unlocking between the cup lid 20 and the main cup body 10.

[0029] Of course, in specific implementation, the axial sliding adjustment of the opening and closing plug rod 22 along the main cup body 10 can also adopt other implementation manners. For example, two limiting holes are arranged on the opening and closing plug rod 22, and the two holes are arranged at intervals along the axis of the opening and closing plug rod 22 in sequence, and pins that can be elastically inserted into the two limiting holes respectively are arranged on the cup lid 20. Or, one end of the locking rotating head 223 is hinged to the guiding sliding rod 222 through a first horizontal rotating shaft, and the middle part is hinged to the top of the cup lid 20 through a second horizontal rotating shaft, and an elastic force is applied to the locking rotating head 223 by a spring, so that the opening and closing plug rod 22 maintains the locking state of driving the locking plug 21 to be inserted into the slot 111.

[0030] In addition, on the basis of the above, for the wedge-shaped fit between the wedge block 221 and the locking plug 21, the present utility model provides two implementation manners:

[0031] Embodiment 1, as Figure 1 shown, the wedge block 221 has a wedge-shaped structure with a narrow upper part and a wide lower part, and the wedge surface is a flat smooth surface structure. When the wedge block 221 slides upward, it will drive the locking plug 21 to slide outward and be inserted into the slot 111 in a plugging fit, while when the wedge block 221 slides downward, it will not prevent the separation of the locking plug 21 from the slot 111. In addition, a return spring 23 for driving the locking plug 21 to be separated from the slot 111 is arranged on the protruding part. During implementation, after only rotating the locking rotating head 223 until the locking surface in the unlocked state faces downward, the locking rotating head 223 under its own gravity and the reverse acting force of the locking plug 21 on the wedge block 221 driven by the return spring 23 cause the opening and closing plug rod 22 to rapidly and stably descend as a whole, and the locking rotating head 223 reaches the unlocked state. If the unlocking method of sliding the opening and closing plug rod 22 upward is adopted, when unlocking, an upward pulling force needs to be applied to the opening and closing plug rod 22 to prevent the reverse acting force of the locking plug 21 on the wedge block 221 driven by the return spring 23 from being insufficient to push the opening and closing plug rod 22 upward, resulting in unstable unlocking. In addition, in cooperation with the limit position of the guiding sliding rod 222 sliding downward when the locking rotating head 223 is in the locked state, the unlocking method of sliding the guiding sliding rod 222 downward can be adopted to prevent the unlocking of the guiding sliding rod 222, while if the unlocking method of sliding the guiding sliding rod 222 upward is adopted, there is a possibility of accidental opening.

[0032] Embodiment 2, not shown in the figure. The wedge block 221 has a wedge surface structure that is narrower at the top and wider at the bottom, and a dovetail groove is provided on the wedge surface of the wedge block 221. The groove length direction of the dovetail groove is distributed along the wedge surface direction. The inner end of the locking plug 21 is provided with a dovetail block that forms a wedge fit with the cavity of the dovetail groove. In this embodiment, the return spring 23 does not need to be provided. By using the wedge fit between the cavity of the dovetail groove and the dovetail block, the horizontal movement of the locking plug 21 can be synchronously driven during the lifting process of the wedge block 221.

[0033] On the above basis, as Figure 4 shown, to lift the locking rotating head 223, an inner groove 2232 is provided on the outer edge of the locking rotating head 223. The penetrating section of the guiding slide bar 222 forms a rotary fit with the groove wall of the inner groove 2232. An elastically deformable convex strip 2231 is fixed on the groove wall of the inner groove 2232. A blocking groove 2221 for accommodating the convex strip 2231 is provided on the penetrating section of the guiding slide bar 222. When the locking rotating head 223 is in the locked state, the convex strip 2231 is located inside the blocking groove 2221. In specific implementation, the convex strip 2231 can be made of materials such as plastic or elastic sheet, which can increase the damping of the convex strip 2231 sliding out of the blocking groove 2221, increase the resistance for the locking rotating head 223 to switch from the locked state to the unlocked state, and prevent the locking rotating head 223 from being accidentally touched and opened.

[0034] Furthermore, as Figure 1 shown, the protruding part has a cylindrical structure with a hollow interior. The opening and closing plug rod 22 and the cup lid 20 are coaxially distributed. As Figure 2 shown, the locking plug 21 is provided with at least two circumferentially evenly distributed around the opening and closing plug rod 22 to ensure the stability of the connection between the cup lid 20 and the main cup body 10.

[0035] In addition, the slot 111 has an annular structure coaxially distributed with the main cup body 10. When the cup lid 20 and the main cup body 10 are installed in a plug-in fit manner, there is no need to consider the distribution position of the locking plug 21.

[0036] In actual implementation, the cup lid 20 can also be hinged to the main cup body 10 through a horizontal hinge seat. In this implementation mode, the slot 111 can have an annular structure or a shape adapted to the locking plug 21.

[0037] It is worth mentioning that, as Figure 1 shown, the main cup body 10 includes a lower cup body 12 and an upper ring body 11 threadedly connected to the opening end of the lower cup body 12. The upper ring body 11 forms the cup mouth of the main cup body 10. This layout method enables the main cup body 10 to have two opening methods: unscrewing the upper ring body 11 or unlocking and opening the cup lid 20, making the opening method of the main cup body 10 more diversified.

[0038] Of course, for those skilled in the art, the present utility model is not limited to the details of the above exemplary embodiments, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0039] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
