Description

Technical Field

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

[0002] Existing water cups are generally divided into open-top water cups without a cup cover and sealable water cups composed of a cup body and a cup cover.

[0003] For closable water cups, the connection structure between the cup lid and the cup body is mostly as described in the text of a convenient and intelligent thermos cup with Chinese patent publication number CN111109977B, in which the cup lid and the cup body are connected by threaded connection. The threaded connection method makes the opening and closing process more laborious; especially when the temperature difference between the two openings of the cup lid is greater, the pressure difference between the inside and outside of the water cup will also be greater, thereby increasing the pressure between the cup lid and the cup mouth, and then the friction between the cup lid and the inner body connection thread increases, making the cup lid more difficult to open.

[0004] Of course, with the increase in the styles of water cups, there are also water cups with a push-type automatic pop-up lid, such as the Chinese patent publication number CN204071512U. The cup lid is hinged to the cup body, and the cup lid is locked by elastic snap-fitting of the protrusion and the buckle. When opening, press the button to release the locking state of the protrusion and the buckle, and the cup lid can be opened quickly. In the existing opening method of the push-to-pop-up lid, although the cup lid is easy to open and close, it only relies on the elastic snap-fitting of the protrusion and the buckle on one side of the cup lid. It is easy to cause the locking of the protrusion and the buckle to loosen due to vibration and bump, thereby causing the cup lid to be accidentally opened. Although in the specific implementation, the loosening of the lock can be prevented by increasing the number of protrusions and buckles, the increase in the number of protrusions and buckles often makes the opening of the cup lid more cumbersome, so it is urgent to solve it. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a push-to-open lid water cup, which not only makes the cup lid easy to open and close, but also ensures a good locking effect between the cup lid and the cup body.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a further solution of the utility model: a hollow cavity is provided inside the cup cover, the rotating seat is rotatably fitted in the hollow cavity, and a plurality of wedge blocks are evenly distributed circumferentially around the axis of the rotating seat below the rotating seat; a plurality of clamping blocks are composed of a linkage part and a clamping part, and the linkage parts of the plurality of clamping blocks are evenly distributed circumferentially around the axis of the rotating seat, and are respectively matched with a wedge block; the clamping part is fixed to the outer wall of the linkage part and radially penetrates the cup cover, the clamping part and the cup cover form a sliding fit, and the penetrating section of the clamping part and the inner flange form a clamping fit.

[0009] As a further solution of the utility model: a first return spring is arranged in the hollow cavity to squeeze the card block to slide elastically outward.

[0010] As a further solution of the utility model: the rotating seat is driven to rotate by a linear pressing mechanism, and the linear pressing mechanism includes a sliding button that slides horizontally on the cup cover. An eccentric column is eccentrically fixed on the rotating seat. The eccentric column is located on the sliding path of the sliding button, and the eccentric column is pushed to move when the sliding button slides inward, thereby driving the rotating seat to rotate; an elastic reset component is provided on the cup cover for elastically pushing the eccentric column to move and reset.

[0011] As a further solution of the utility model: the cup cover is provided with a second return spring for driving the sliding button to slide outward and return to its original position.

[0012] As a further solution of the utility model: the linear pressing mechanism is arranged in two groups symmetrically distributed along the central axis of the cup cover.

[0013] As a further solution of the utility model: a sealing inner convex ring is arranged inside the cup body, and when the clamping block and the inner flange form a clamping fit, the outer periphery of the bottom end of the cup cover forms a sealing abutment with the sealing inner convex ring.

[0014] As a further solution of the utility model: a sealing ring is fixedly connected to the outer periphery of the bottom end of the cup cover.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model abandons the traditional locking structure of the single-sided card block, and instead adopts a method of setting the card blocks into several groups evenly distributed around the axis of the rotating seat, and relies on the action of the rotating seat to provide a single power source. When the rotating seat rotates, all the wedge blocks are driven to squeeze the corresponding card blocks to slide inward to unlock, realizing the effect of one-to-many, and finally achieving the balance between convenient opening and closing and good locking effect.

[0017] 2. The hollow cavity accommodates the linkage part of the rotating seat and the clamping block, and only the clamping part penetrates to the outer wall of the cup cover, so that the outer wall of the cup cover is relatively neat; so that after the cup cover and the cup body are combined, the outer wall of the cup cover and the inner wall of the cup body are fitted as large as possible, thereby ensuring the stability of the cup cover and the cup body after combination.

[0018] 3. In order to realize the elastic sliding of the card block outward, a first return spring is arranged in the hollow cavity to force the card block to slide outward elastically.

[0019] 4. The rotating seat is driven to rotate by a linear pressing mechanism. The cup cover and the cup body can be opened and closed by simply pressing the linear pressing mechanism, which further ensures the convenience of opening and closing the cup cover. In addition, the eccentric column eccentrically distributed on the rotating seat is driven by a sliding button. In the specific implementation, the eccentricity of the eccentric column on the rotating seat can be increased to increase the torque that drives the rotating seat to rotate, thereby making the pressing process of pressing the sliding button to drive the rotating seat to rotate more labor-saving.

[0020] 5. The cup cover is provided with a second reset spring for driving the sliding button to slide outward and reset. Based on the elastic reset eccentric column and the sliding button of the elastic reset component, the second reset spring is used to drive the sliding button to slide and reset alone, thereby reducing the resistance of the elastic reset component during the reset process, ensuring that the eccentric column and the sliding button can achieve stable reset.

[0021] 6. The linear pressing mechanism is arranged in two groups symmetrically distributed along the central axis of the cup cover, so that when unlocking the cup cover, the user can press one group of linear pressing mechanisms with the thumb and index finger respectively, and the two groups of linear pressing mechanisms synchronously drive the rotating seat to rotate, making the unlocking process of driving the rotating seat to rotate more labor-saving.

[0022] 7. To ensure a good sealing effect after the cup body and the cup cover are combined, a sealing inner convex ring is provided inside the cup body. When the clamping block and the inner flange form a snap fit, the outer periphery of the bottom end of the cup cover forms a sealing abutment with the sealing inner convex ring.

[0023] 8. A sealing ring is fixedly connected to the outer periphery of the bottom end of the cup cover, which further ensures the sealing performance of the sealing abutment between the outer periphery of the bottom end of the cup cover and the sealing inner convex ring.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:

[0031] The specific structure of the utility model refers to Figure 1-4 As shown, its main structure includes a cup body 10 and a cup cover 20 inserted into the opening of the cup body 10 and forming a sealing fit with the cup body 10. Figure 1 As shown, the inner circumference of the opening of the cup body 10 is provided with an inner flange 11, and a clamping block 21 that can slide elastically outward and form a snap fit with the inner flange 11 is slidably provided on the cup cover 20, thereby realizing the connection between the cup cover 20 and the cup body 10. The cup cover 20 is coaxially rotatably provided with a rotating seat 23, as shown in FIG. Figure 1 and Figure 2 As shown, a wedge block 231 is provided on the rotating seat 23 to cooperate with the clamping block 21. When the rotating seat 23 rotates, the wedge block 231 squeezes the clamping block 21 to slide inward to unlock. Figure 2As shown, a block 21 and a wedge 231 are used as a locking component, and the locking components are arranged as a plurality of groups uniformly distributed around the axis of the rotating seat 23; therefore, in specific implementation, the number of locking components can be increased according to the needs to improve the locking effect between the cup cover 20 and the cup body 10, and the plurality of locking components are also synchronously unlocked by pressing the linear travel button mechanism, which not only ensures the convenience of opening and closing the cup cover 20, but also effectively ensures the locking effect between the cup cover 20 and the cup body 10. In addition, the sealing part between the cup cover 20 and the cup body 10 is located below the locking component, which can prevent the liquid in the cup body 10 from flowing out through the gap at the locking component, resulting in a decrease in the sealing of the water cup. The clamping blocks 21 are arranged in a plurality of groups uniformly distributed around the axis of the rotating seat 23, and a single power source is provided by the movement of the rotating seat 23. When the rotating seat 23 rotates, all the wedge blocks 231 are driven to squeeze the corresponding clamping blocks 21 to slide inward to unlock, thereby realizing a one-to-many effect, and finally achieving the balance between convenient opening and closing and good locking effect.

[0032] On the basis of the above, if Figure 1 As shown, a hollow cavity is provided inside the cup cover 20, and the rotating seat 23 is rotatably fitted in the hollow cavity, and a plurality of wedge blocks 231 are uniformly distributed circumferentially below the rotating seat 23 around the axis of the rotating seat 23. The clamping block 21 is composed of a linkage portion 211 and a clamping portion 212, and a plurality of clamping blocks 21 are composed of a linkage portion 211 and a clamping portion 212. The linkage portions 211 of a plurality of clamping blocks 21 are uniformly distributed circumferentially around the axis of the rotating seat 23, and are respectively matched with a wedge block 231, thereby realizing that the rotating seat 23 drives a plurality of clamping blocks 21 to slide inward and unlock at the same time during the rotation process. The clamping portion 212 is fixed to the outer wall of the linkage portion 211 and radially penetrates the cup cover 20, and the clamping portion 212 forms a sliding fit with the cup cover 20, and the penetration section of the clamping portion 212 forms a clamping fit with the inner flange 11. This arrangement accommodates the rotating seat 23 and the linkage part 211 of the clamping block 21 through the hollow cavity, and only the clamping part 212 penetrates to the outer wall of the cup cover 20, so that the outer wall of the cup cover 20 is relatively neat; so that after the cup cover 20 is combined with the cup body 10, the fitting area between the outer wall of the cup cover 20 and the inner wall of the cup body 10 is as large as possible, thereby ensuring the stability of the cup cover 20 and the cup body 10 after being combined.

[0033] Specifically, Figure 3As shown, the rotating seat 23 is driven to rotate by the linear pressing mechanism, and the linear driving force of the linear pressing mechanism is converted from the rotating seat 23 into a rotational force, and the block 21 is unlocked by the rotation of the rotating seat 23. Therefore, in actual implementation, only the linear pressing mechanism needs to be pressed to open and close the cup cover 20 and the cup body 10, thereby ensuring the convenience of opening and closing the cup cover 20. Specifically, the linear pressing mechanism includes a sliding button 24 that slides horizontally on the cup cover 20, and an eccentric column 232 is eccentrically fixed on the rotating seat 23. The eccentric column 232 is located on the sliding path of the sliding button 24, and the eccentric column 232 is pushed to move when the sliding button 24 slides inward, thereby driving the rotating seat 23 to rotate, thereby realizing the conversion of the horizontal sliding force of the sliding button 24 into the driving force for driving the rotating seat 23. In addition, the sliding button 24 is used to drive the eccentric column 232 eccentrically distributed on the rotating seat 23. In the specific implementation, by increasing the eccentricity of the eccentric column 232 on the rotating seat 23, the torque that pushes the rotating seat 23 to rotate can be increased, so that the pressing process of pressing the sliding button 24 to push the rotating seat 23 to rotate is more labor-saving. In addition, in order to enable the rotating seat 23 to automatically reset after rotating the unlocking block 21, an elastic reset component 233 for elastically pushing the eccentric column 232 to move and reset is provided on the cup cover 20. Specifically, the elastic reset component 233 can be composed of a compression spring and a reset push plate, the reset push plate and the sliding button 24 have the same sliding path, and the sliding button 24 and the reset push plate are respectively distributed on both sides of the eccentric column 232. When the sliding button 24 slides inward, the eccentric column 232 and the reset push plate are pushed to slide. At this time, the compression spring elastically contracts, and after the pressing force on the sliding button 24 is released, the compression spring squeezes the reset push plate, the eccentric column 232 and the sliding button 24 to move and reset. Of course, in a specific implementation, the elastic reset component 233 can also adopt a metal spring that pushes the eccentric column 232 to reset or a torsion spring that drives the rotating seat 23 to rotate and reset.

[0034] In addition, if Figure 3 As shown, the cup cover 20 is provided with a second return spring 25 for driving the sliding button 24 to slide outward and return to its original position. On the basis of the elastic return assembly 233 elastically returning the eccentric column 232 and the sliding button 24, the second return spring 25 is used to drive the sliding button 24 to slide and return to its original position alone, thereby reducing the resistance of the elastic return assembly 233 during the return process, and ensuring that the eccentric column 232 and the sliding button 24 can be returned to their original position stably.

[0035] On the basis of the above, if Figure 1As shown, the linear pressing mechanism is arranged in two groups symmetrically distributed along the central axis of the cup cover 20, so that in the operation of unlocking the cup cover 20, the user can press one group of linear pressing mechanisms respectively with the thumb and index finger, and the two groups of linear pressing mechanisms synchronously drive the rotating seat 23 to rotate, making the unlocking process of driving the rotating seat 23 to rotate more labor-saving.

[0036] It is worth mentioning that, in a specific implementation, the linear pressing mechanism may also adopt other implementations, such as the linear pressing mechanism is set as a horizontally sliding rack, and a gear meshing with the rack is coaxially fixed on the rotating seat 23. By pressing the rack, the rotating seat 23 can be driven to rotate through the meshing of the rack and the gear.

[0037] In addition, in order to realize the elastic sliding of the block 21 outward, as Figure 1 As shown, a first return spring 22 is arranged in the hollow cavity to squeeze the card block 21 to slide elastically outward. Of course, in specific implementation, a mechanism with elastic squeezing force such as a metal spring sheet can also be used.

[0038] In order to ensure a good sealing effect after the cup body 10 and the cup cover 20 are combined, Figure 1 As shown, a sealing inner convex ring 12 is provided inside the cup body 10, and when the clamping block 21 is engaged with the inner flange 11, the outer periphery of the bottom end of the cup cover 20 forms a sealing contact with the sealing inner convex ring 12. In addition, a sealing ring 30 is fixedly connected to the outer periphery of the bottom end of the cup cover 20, which further ensures the sealing performance of the sealing contact between the outer periphery of the bottom end of the cup cover 20 and the sealing inner convex ring 12.

[0039] Of course, for those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims.
