Description

Technical Field

[0001] This application relates to the field of daily-use insulated containers technology, and in particular to a portable insulated cup. Background Technology

[0002] Thermos cups are commonly used drinking containers in daily life. Because they can keep water at a certain temperature for a long time, they are widely used in home, office, and outdoor travel scenarios.

[0003] Current insulated cups are typically carried using only a fixed handle on the side of the cup or a simple handle on the top of the lid. This single method has obvious drawbacks: when users need to carry other items, the fixed handle or simple handle cannot free their hands, making it inconvenient to carry; if the insulated cup has a large capacity, carrying it for a long time will increase the burden on the hands, and the insulated cup is prone to slipping due to hand fatigue; in addition, although some insulated cups are equipped with external shoulder straps, the shoulder straps are mostly independent accessories, which are easy to lose and cannot be stored when not in use. The swaying of the shoulder strap during carrying can cause interference and affect the user experience. Therefore, a more portable insulated cup is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a portable thermos cup to solve the problems mentioned in the background art.

[0005] The portable thermos provided in this application adopts the following technical solution:

[0006] A portable thermos cup includes a cup body, a cup lid is provided on the top outer wall of the cup body, and a handle is rotatably connected to the top outer wall of the cup lid, the handle being embedded in the circumferential outer wall of the cup lid;

[0007] The outer wall of the cup body is provided with a storage groove, the inner wall of the storage groove is fixedly connected to a fixed shaft, the outer wall of the fixed shaft is rotatably connected to a rotating cylinder, the outer wall of the rotating cylinder is provided with a shoulder strap, and the end of the shoulder strap away from the rotating cylinder is movably connected to the outer circumference of the cup body through a connecting buckle.

[0008] Preferably, a torsion spring is provided between the fixed shaft and the rotating drum, with one end of the torsion spring fixedly connected to the outer wall of the fixed shaft and the other end fixedly connected to the inner wall of the rotating drum.

[0009] Preferably, the outer wall of the cup lid is equipped with a limiting component for fixing the handle, which includes a movable block, a locking block and a spring. The inside of the cup lid is provided with a movable groove. The movable block is slidably connected to the inner wall of the movable groove. The locking block is fixedly connected to the outer wall of the movable block, and its end away from the movable block passes through the cup lid.

[0010] Preferably, the locking block is fixedly connected to the outer wall of the movable block on the side opposite to the locking block, and its other end is fixedly connected to the inner wall of the movable groove. The inner wall of the handle is provided with a locking groove, and the end of the locking block located outside the cup lid is adapted to and inserted into the locking groove.

[0011] Preferably, the top outer wall of the cup lid is also provided with a toggle groove, which is connected to the interior of the movable groove. A connecting rod is slidably connected inside the toggle groove. The bottom end of the connecting rod is fixedly connected to the movable block, and the top end of the connecting rod is fixedly connected to a toggle block.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The combination of handle and shoulder strap design provides users with two options: hand-carrying and shoulder-carrying. When users need to handle other tasks, they can unfold the shoulder strap to carry it on their shoulder or crossbody, effectively freeing their hands. When carrying a large-capacity thermos, the shoulder-carrying method can distribute the weight to the shoulder, avoiding hand fatigue and the risk of slipping caused by carrying it for a long time. It is suitable for various scenarios such as home, office, and outdoor travel, significantly improving the convenience of carrying.

[0014] 2. This utility model integrates the shoulder strap and cup body into one design. The shoulder strap is automatically stored by the cooperation of torsion spring and rotating cylinder. When not in use, it can be completely stored in the storage slot of the cup body, so there is no need to worry about losing the accessories. At the same time, the handle can be folded and embedded into the outer wall of the cup lid, and is firmly fixed by the limiting component, avoiding interference caused by the swaying of the shoulder strap and the protrusion of the handle during carrying, thus taking into account the practicality of the product and the user experience.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a portable thermos cup. (See also...) Figure 1-5 A portable thermos cup includes a cup body 1 and a cup lid 2. The cup lid 2 is fitted to the top outer wall of the cup body 1. The two are connected by threads to achieve detachable fixation and ensure sealing performance. The top outer wall of the cup lid 2 has a reserved rotating mounting position. The handle 21 is rotatably connected to the mounting position through a pivot structure. The outer contour of the handle 21 is adapted to the circumferential outer wall of the cup lid 2. When in the storage state, it can be completely embedded in the outer contour of the cup lid 2 without protrusion.

[0024] A storage groove 11 is provided on the outer wall of the cup body 1 at a corresponding position. The inner wall of the storage groove 11 has a pre-set fixing point. The two ends of the fixing shaft 12 are fixed to the inner wall of the storage groove 11 by welding or integral molding. The rotating cylinder 14 is sleeved on the outer wall of the fixing shaft 12. The two are in clearance fit, so that the rotating cylinder 14 can rotate freely around the fixing shaft 12. One end of the shoulder strap 3 is fixed to the outer wall of the rotating cylinder 14 by adhesive or sewing, and the other end is equipped with a connecting buckle. The outer wall of the cup body 1 has a matching buckle seat at a corresponding position. The shoulder strap 3 is movably connected by the cooperation of the connecting buckle and the buckle seat.

[0025] A torsion spring 13 is installed between the fixed shaft 12 and the rotating cylinder 14. One end of the torsion spring 13 is tightly attached to and fixed to the outer wall of the fixed shaft 12, and the other end is embedded in the pre-set mounting groove on the inner wall of the rotating cylinder 14 for fixation. When the shoulder strap 3 needs to be unfolded, the shoulder strap 3 is pulled outward, causing the rotating cylinder 14 to rotate around the fixed shaft 12. At this time, the torsion spring 13 deforms and stores elastic potential energy. When the shoulder strap 3 is released, the torsion spring 13 releases elastic potential energy, causing the rotating cylinder 14 to rotate in the opposite direction, automatically wrapping the shoulder strap 3 around and storing it on the outer wall of the rotating cylinder 14, and finally storing the shoulder strap 3 in the storage groove 11. It should be noted that the elastic force parameters of the torsion spring 13 in this embodiment have been adapted and designed so that the overall weight of the thermos (including when it is filled with liquid) can overcome the elastic force of the torsion spring 13. Under the action of the weight of the thermos itself, the shoulder strap 3 remains taut, and the elastic force of the torsion spring 13 cannot drive the rotating cylinder 14 to rotate in the opposite direction, ensuring that the shoulder strap 3 will not shrink when used by the user.

[0026] The limiting component is installed on the outer wall of the cup lid 2 to fix and unlock the handle 21. Its specific structure and assembly are as follows:

[0027] The cup lid 2 has an internal movable groove 41 with a smooth inner wall. The movable block 42 is slidably connected to the movable groove 41. The locking block 43 is integrally formed on the outer wall of the movable block 42. The cup lid 2 has a through hole at a corresponding position. The end of the locking block 43 away from the movable block 42 extends through the through hole to the outside of the cup lid 2. The spring 45 is located on the side of the movable block 42 away from the locking block 43. One end of the spring 45 is fixed against the outer wall of the movable block 42, and the other end is fixed against the inner wall of the movable groove 41. Under normal conditions, the spring 45 is in a naturally extended state, pushing the movable block 42 to cause the locking block 43 to extend outward.

[0028] The inner wall of the handle 21 has a slot 211 corresponding to the position of the locking block 43. The shape and size of the slot 211 are adapted to the protruding end of the locking block 43. When the handle 21 is in the folded state, the locking block 43 is inserted into the slot 211 to fix the handle 21. When it is necessary to rotate the handle 21, the locking block 43 is disengaged from the slot 211 by operating the unlocking structure, and the handle 21 can be rotated for use.

[0029] The top outer wall of the cup lid 2 is provided with a toggle groove 44, which is connected to the interior of the movable groove 41. The length direction of the toggle groove 44 is consistent with the sliding direction of the movable block 42. The connecting rod 46 is adapted to slide in the toggle groove 44. Its bottom end is fixedly connected to the top of the movable block 42 by thread or welding, and its top end is integrally formed with the toggle block 47. By toggle the toggle block 47 and slide it along the toggle groove 44, the connecting rod 46 can be driven to move synchronously, thereby pulling the movable block 42 to compress the spring 45, so that the locking block 43 is disengaged from the locking groove 211, and the handle 21 is unlocked.

[0030] The implementation principle of a portable thermos cup in this application embodiment is as follows: Under normal conditions, the spring 45 is in a naturally extended state, and its elasticity pushes the movable block 42 to slide along the movable groove 41 towards the handle 21, causing the locking block 43 to pass through the through hole of the cup lid 2 and precisely engage with the locking groove 211 on the inner wall of the handle 21. At this time, the handle 21 is limited by the locking block 43 and is completely embedded in the outer contour of the cup lid 2, maintaining a folded storage state without protrusion.

[0031] When the handle 21 is needed, the lever 47 is moved away from the handle 21. The lever 47 slides along the lever groove 44, and the moving block 42 moves synchronously through the connecting rod 46, compressing the spring 45 and causing the locking block 43 to disengage from the locking groove 211, thus releasing the restriction on the handle 21. At this time, the handle 21 can rotate freely around the rotating shaft structure at the top of the cup lid 2 until it is adjusted to a suitable angle for carrying.

[0032] After releasing the lever 47, the spring 45 releases its elastic potential energy, pushing the movable block 42 to reset. The locking block 43 extends again and engages with the corresponding slot 211 of the handle 21, fixing the handle 21 in its current position and ensuring that the handle 21 does not shake or rotate during the carrying process.

[0033] The automatic retraction and tension of the shoulder strap 3 during use are achieved through the coordination of the torsion spring 13 and the weight of the thermos. The core logic is as follows:

[0034] When it is necessary to carry it on the shoulder, pull the shoulder strap 3 outward. The shoulder strap 3 drives the rotating cylinder 14 to rotate around the fixed shaft 12. The torsion spring 13, which is sleeved between the fixed shaft 12 and the rotating cylinder 14, deforms with the rotation of the rotating cylinder 14 and continuously stores elastic potential energy. After the connecting buckle at the end of the shoulder strap 3 is connected and fixed to the buckle seat on the outer wall of the cup body 1, the unfolding process is completed.

[0035] Because the elastic parameters of the torsion spring 13 are adapted and designed, the overall weight of the thermos (including when it is filled with liquid) is greater than the elastic force of the torsion spring 13. Under the pulling action of the thermos's own weight, the shoulder strap 3 remains taut, and the resulting tension cancels out the elastic potential energy of the torsion spring 13, preventing the rotating cylinder 14 from rotating in the opposite direction. This ensures that the shoulder strap 3 does not shrink during use and stably supports the thermos.

[0036] When the shoulder strap 3 is not being carried, there is no external force acting on the shoulder strap 3, and the pulling effect of the thermos cup on the shoulder strap 3 disappears. The torsion spring 13 releases the stored elastic potential energy, which drives the rotating cylinder 14 to rotate in the opposite direction, so that the shoulder strap 3 is evenly wrapped around the outer wall of the rotating cylinder 14. As the rotating cylinder 14 continues to rotate, the shoulder strap 3 is gradually stored in the storage groove 11 of the cup body 1 until the shoulder strap 3 is parallel to the outer wall of the cup body 1, thus achieving neat storage of the components.
