Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermos cup technology, and specifically relates to a magnetic lid thermos cup. Background Technology
[0002] Many existing thermos cup lids use a spring-loaded buckle structure to lock the lid. To prevent the lid from being opened accidentally, a locking ring is usually added to further lock the lid to the cup body. The drawback of this structure is that when the spring-loaded buckle is connected, the lid is usually hooked by the top of the buckle. This structure is prone to jamming between the lid and the spring-loaded buckle when opening, making it difficult to open smoothly. In addition, in actual use, users may easily forget to tighten the locking ring, making it easy for the lid to be opened accidentally. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a magnetic lid thermos cup to solve the problems existing in the prior art.

[0006] Preferably, the top of the cup lid body is integrally formed with an upwardly extending water outlet, and the side of the cup lid body is provided with an installation cavity. The elastic fastener includes a press buckle, and a connecting shaft is provided transversely through the installation cavity. The press buckle is placed in the installation cavity, and a travel limiting groove is opened on the press buckle. The connecting shaft passes through the travel limiting groove. A spring is provided between the inner end of the press buckle and the inner end wall of the installation cavity. By providing the travel limiting groove and the spring, the press buckle is telescopically connected in the installation cavity. The top of the press buckle is provided with a snap-fit arm. Correspondingly, the sealing cover is provided with a locking rod. The top of the installation cavity is provided with a plug-in groove. After the sealing cover is closed, the locking rod is inserted into the plug-in groove and snap-fitted with the snap-fit arm.
[0007] Preferably, the locking rod is vertically disposed on the bottom surface of the sealing cover, and the bottom end of the locking rod forms a first sectional structure; correspondingly, a second sectional structure is formed on the top end of the insertion groove. When the sealing cover is pressed down, the first sectional structure is pressed onto the second sectional structure, causing the pressing buckle to retract into the mounting cavity, and the locking rod enters the insertion groove; a hook-shaped part is formed inside the insertion groove, and a snap-fit window is formed on the locking rod. After the sealing cover is closed, the hook-shaped part is placed in the snap-fit window.
[0008] Preferably, the magnetic suction assembly includes a first magnet disposed on the cup lid body and a second magnet disposed on the sealing lid body. When the sealing lid body is closed on the cup lid body, the first magnet and the second magnet are magnetically connected.
[0009] Preferably, a downwardly protruding hemispherical protrusion is formed on the top surface of the cup lid body, and a first interlocking groove is formed on the hemispherical protrusion, in which a concave first magnet is interlocked; correspondingly, a concave hemispherical groove is provided on the sealing cover body, and a second interlocking groove is formed in the hemispherical groove, in which a second magnet is interlocked.
[0010] Preferably, the sealing cover has an upwardly extending socket cavity that fits onto the water outlet, and a sealing plug is provided on the top wall of the socket cavity.
[0011] Preferably, the cup lid body is provided with a hinge shaft, the sealing lid body is hinged to the hinge shaft, and a handle is also hinged to the hinge shaft.
[0012] In summary, the present invention has the following main advantages:
[0013] The push-button telescopic connection of the elastic fastener in this application is located inside the mounting cavity, and the locking rod is vertically inserted into the insertion slot, making it less prone to jamming when unlocking; in addition, a magnetic component is provided, so even if the sealing cover is accidentally opened, there will be no water leakage, thus improving safety.
