DETAILED DESCRIPTION

[0025] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, and those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary, and should not be interpreted as limiting the protection scope of the utility model.

[0026] It should be noted that: similar signs represent similar items in the following drawings, therefore, once an item is defined in one drawing, it can not be further defined and explained in the subsequent drawings.

[0027] This embodiment mainly describes a double-locking heat preservation coffee cup, and the specific embodiments are as follows:

[0028] As Figures 1 to 6As shown, a double-locked heat-insulating coffee cup includes a cup body 1 and a cup cover 2 covering the mouth of the cup body 1. The cup cover 2 is provided with a sliding groove 21 along the radial direction thereof, and a drinking opening 22 in communication with the cup body 1 is arranged near the edge of the cup cover 2. A sliding cover 3 is slidably arranged in the sliding groove 21 and can move along the sliding groove 21 to open or close the drinking opening 22. A first elastic protrusion 211 is arranged on the side wall of the sliding groove 21, and a first clamping groove 311 is arranged on the two side walls of the sliding cover 3 and cooperates with the first elastic protrusion 211. When the sliding cover 3 slides to block the drinking opening 22, the first elastic protrusion 211 cooperates with the first clamping groove 311 to preliminarily lock the sliding cover 3, preventing the sliding cover 3 from accidentally sliding due to slight shaking during normal use, thereby ensuring that the coffee or other beverages in the cup body 1 will not accidentally flow out due to loosening of the sliding cover 3. An installation channel 313 extending along the width direction of the sliding cover 3 and penetrating through the two side walls of the sliding cover 3 is arranged in the interior of the sliding cover 3, and an elastic limiting piece 4 is arranged in the installation channel 313, with the two ends of the elastic limiting piece 4 extending out of the sliding cover 3 to form a limiting part. A limiting groove 213 cooperating with the limiting part is arranged on the two side walls of the sliding groove 21, and an extrusion block 5 extruding the elastic limiting piece 4 is arranged on the top of the sliding cover 3. When the sliding cover 3 blocks the drinking opening 22, the limiting part extends into the limiting groove 213 to further lock the sliding cover 3, thereby enhancing the stability of the sliding cover 3 and enabling it to maintain a closed state even when subjected to external impact or shaking, effectively preventing leakage of the beverages. When it is necessary to open the drinking opening 22, the extrusion block 5 is pressed to enable the limiting part to disengage from the limiting groove 213, and the sliding cover 3 is pushed away from the drinking opening 22 to enable the first elastic protrusion 211 to disengage from the first clamping groove 311, thereby opening the drinking opening 22. The design of the double-locked structure requires that the extrusion block 5 be pressed and the sliding cover 3 be pushed away from the drinking opening 22 to open the drinking opening 22, and the drinking opening 22 cannot be opened smoothly by merely pushing the sliding cover 3, thereby avoiding accidental opening of the drinking opening 22 due to sliding of the sliding cover 3 caused by external pushing or impact during carrying and use, preventing leakage of the beverages and occurrence of waste and scalding. The design not only ensures the stability of the sliding cover 3 in a closed state, but also enables the user to easily open the drinking opening 22 when necessary, thereby improving the safety and convenience of use of the coffee cup.

[0029] As Figure 4As shown, the top of the sliding cover 3 is provided with a downwardly extending mounting groove 314, which is in communication with the mounting channel 313. The two side walls of the mounting groove 314 are provided with guide grooves 315, and the pressing block 5 is provided with guide blocks 51 that cooperate with the two guide grooves 315. The pressing block 5 is provided in the mounting groove 314 by cooperation of the guide blocks 51 and the guide grooves 315. By providing the mounting groove 314, the guide grooves 315 and the guide blocks 51, a stable sliding path is provided for the pressing block 5, so that it can accurately act on the elastic limiting piece 4 during pressing, ensuring that the limiting portion can smoothly separate from the limiting groove 213. This structural design not only improves the reliability of the opening operation of the sliding cover 3, but also makes the operation process smoother, so that the user can more easily control the opening and closing of the sliding cover 3 during use, improving the user experience of the coffee cup.

[0030] Specifically, the bottom of the mounting groove 314 is lower than the mounting channel 313, and the bottom of the mounting groove 314 is provided with a protruding column 316 perpendicular to the mounting channel 313, and the elastic limiting piece 4 passes above the protruding column 316. The bottom of the pressing block 5 has pressing rods 52 on both sides of the protruding column 316, and the two pressing rods 52 have a spacing therebetween, forming an avoidance space 53 that avoids interference with the protruding column 316. The provision of the protruding column 316 provides a stable support point for the elastic limiting piece 4, so that it can maintain good elastic performance when it is retracted under pressure. At the same time, the cooperation of the pressing rods 52 and the avoidance space 53 ensures that the pressing block 5 does not collide or jam with the protruding column 316 during pressing, further improving the smoothness and reliability of the opening operation of the sliding cover 3. This structural design effectively avoids the difficulty or damage caused by interference between components, prolongs the service life of the coffee cup, and also provides a more comfortable operation experience for the user.

[0031] As shown in Figure 2 and Figure 4 The elastic limiting piece 4 includes an elastic sheet 41 and limiting blocks 42 fixed at both ends of the elastic sheet 41, and the limiting blocks 42 form the limiting portion. The end of the limiting block 42 is spherical. The elastic sheet 41 has good elastic performance and can deform when pressed and quickly recover to its original shape after the pressure is released. The spherical design of the end of the limiting block 42 makes the cooperation between the limiting portion and the limiting groove 213 more compact and flexible. When the limiting portion extends into the limiting groove 213, the spherical surface closely fits the inner wall of the limiting groove 213, effectively preventing the sliding cover 3 from loosening when subjected to external force; when the limiting portion is pressed to separate from the limiting groove 213, the spherical surface reduces the friction between the limiting groove 213 and the limiting portion, allowing the sliding cover 3 to slide more smoothly. This structural design of the elastic limiting piece 4 not only ensures the locking stability of the sliding cover 3, but also improves the flexibility of the opening and closing of the sliding cover 3, achieving a balance between reliability and convenience during use of the coffee cup.

[0032] Specifically, the limiting block 42 is a sphere. Designing the limiting block 42 into a spherical shape further enhances the cooperation between the limiting portion and the limiting groove 213. The surface of the sphere is smoother, and the contact area with the inner wall of the limiting groove 213 is relatively small, which makes the frictional force that the limiting portion receives when entering or leaving the limiting groove 213 smaller, and the sliding of the sliding cover 3 more smooth. This structural design not only improves the use performance of the coffee cup, but also enables it to maintain good locking and opening functions during long-term use, meeting the high-quality requirements of users for the thermal coffee cup.

[0033] Specifically, the sliding groove 21 is provided with sliding rails 24 on the two side walls, and the sliding cover 3 is provided with sliding blocks 31 that extend into the sliding groove 21 and can slide along the sliding groove 21. The cooperation of the sliding rails 24 and the sliding blocks 31 provides stable guidance for the sliding of the sliding cover 3, making the movement of the sliding cover 3 in the sliding groove 21 more stable and smooth. This structural design effectively avoids the situation that the sliding cover 3 stalls or deviates during sliding, ensuring that the sliding cover 3 can accurately reach the predetermined position to achieve the opening and closing control of the drinking port 22. At the same time, the cooperation of the sliding rails 24 and the sliding blocks 31 can also reduce the wear between the sliding cover 3 and the sliding groove 21, prolong the service life of the coffee cup, and improve its overall performance and reliability.

[0034] As shown in Figure 3 two first elastic protrusions 211 are symmetrically arranged in the two sliding grooves 21 and located near the drinking port 22. The two sliding rails 24 are provided with second elastic protrusions 212 away from the drinking port 22, and the sliding blocks 31 are provided with second clamping grooves 312 away from the first clamping grooves 311. When the sliding cover 3 slides away from the drinking port 22 to completely open the drinking port 22, the second elastic protrusions 212 are clamped into the second clamping grooves 312. This double elastic protrusion and double clamping groove locking structure not only realizes locking through the first elastic protrusions 211 and the first clamping grooves 311 when the sliding cover 3 blocks the drinking port 22, but also realizes locking through the second elastic protrusions 212 and the second clamping grooves 312 when the sliding cover 3 completely opens the drinking port 22. This design effectively guarantees the stability of the sliding cover 3 in both states, further reduces the risk of accidental sliding of the sliding cover 3, and improves the safety of the coffee cup during use.

[0035] Specifically, the chute 21 is also provided with an air outlet hole 23, and the slide cover 3 is provided with a first sealing ring 32 matched with the drinking opening 22 and a second sealing ring 33 matched with the air outlet hole 23. When the limiting portion is matched with the limiting groove 213 to limit the slide cover 3, the drinking opening 22 is covered by the first sealing ring 32, and the air outlet hole 23 is covered by the second sealing ring 33. At this time, a good sealing effect is formed between the slide cover 3 and the chute 21, effectively preventing the coffee or other beverages in the cup body 1 from leaking from the drinking opening 22 and the air outlet hole 23, and also avoiding the entry of external air into the cup body 1, affecting the heat preservation effect of the coffee. When the second elastic protrusion 212 is clamped into the second clamping groove 312, the drinking opening 22 is separated from the covering of the first sealing ring 32, and the air outlet hole 23 is separated from the covering of the second sealing ring 33. This sealing structure is combined with the opening and closing state of the slide cover 3, which not only ensures the sealing performance of the slide cover 3 in the closed state, but also enables normal drinking and air exhaust operation when the slide cover 3 is opened, achieving a perfect balance between sealing and use function, and further improving the overall performance of the heat preservation coffee cup.

[0036] Specifically, the top surface of the cup cover 2 gradually inclines downward from the side away from the drinking opening 22 to the side of the drinking opening 22. This inclined design makes the structure of the cup cover 2 more in line with the ergonomic principle. When the user holds the coffee cup for drinking, the inclined top surface of the cup cover 2 can better guide the coffee to flow to the drinking opening 22, making the drinking process more smooth and natural. At the same time, this shape design also helps to reduce the coffee residue on the surface of the cup cover 2, avoiding the cleaning difficulty or odor caused by coffee residue, and improving the hygiene and use comfort of the coffee cup.

[0037] As shown in Figure 1 and Figure 2 , the cup body 1 is fixedly connected with a handle 6 on the side wall. The handle 6 provides users with more convenient use experience. When drinking coffee, the user can hold the coffee cup stably by holding the handle 6, avoiding the problem of burning hands or falling caused by directly contacting the cup body 1. The design of the handle 6 can also increase the overall aesthetics of the coffee cup, making it more in line with the aesthetic needs of modern home and office environment. In addition, the fixed connection mode of the handle 6 ensures its firmness and stability during use. Even if the coffee cup is full of liquid, the user can easily pick up or move the coffee cup, further improving the practicality and user experience of the coffee cup.
