Description

Technical Field

[0001] The invention relates to a heat-insulating container, and in particular to a switch structure of the heat-insulating container. Background Art

[0002] The switch structure of conventional thermal insulation containers is elastically pressed and manually movable. This structural method requires sacrificing the product's appearance space, limiting the design of the product's appearance. In addition, the general switch structure cannot control two switches that are far away with one hand at the same time, and has high requirements for the structural space and cannot meet the appearance and structural space of a variety of products. In order to diversify the products of thermal insulation containers and meet various needs, people continue to use new technologies and new methods to develop thermal insulation container products with different structures to meet the different needs of the market. Summary of the invention

[0004] The present invention includes: a snap cover, a screw, a flywheel, a dial, a driving wheel, a switch sheet, a washer, and an outer cover, wherein the snap cover is mounted on the flywheel, the dial is embedded in the flywheel, the snap cover is installed in the central hole of the outer cover, a ring of gears is provided on the inner wall of the bottom of the central hole of the outer cover, a gear is provided at the bottom of the driving wheel, a gear is provided at the top of the driving wheel and meshes with the ring of gears on the outer cover, the driving wheel is mounted on the central axis of the dial, a small cylinder is provided on the dial, an arc groove is provided on the gear sheet to match the small cylinder, the small cylinder is embedded in the arc groove on the gear sheet, a plurality of switch sheets are provided at the bottom of the driving wheel, a rack is provided on each side edge of the switch, the rack meshes with the gear at the bottom of the driving wheel, a washer is provided at the end of the central axis of the dial to prevent the driving wheel and the switch sheet from falling off. A locking tongue is provided at the end of the switch sheet. When the dial rotates, the small cylinder on the dial drives the arc groove to rotate, thereby rotating the gear at the bottom of the driving wheel. The gear drives the lock tongues of the right switch piece and the left switch piece to extend outward and snap onto the relevant matching parts to achieve a locked state or retract inward to achieve an open state.

[0005] The driving wheel is a two-layer structure, with an arc-shaped tooth plate on the top, similar to an S shape, and a pair of blunt teeth cooperating with the outer cover gear ring are provided at symmetrical positions on the outside of the arc.

The ends of the right switch piece and the left switch piece are respectively provided with locking tongues, which extend out of the outer cover to move inwards and outwards.

[0008] The advantages of the present invention are that it does not require a wide structural space, can perfectly solve the appearance structural space and achieve perfect structural functional characteristics, can meet the appearance structural space of a variety of products, diversify the products of the thermal insulation container, and ensure that the product appearance design is not affected by the switch structure. And it is easy to disassemble. It is easy to operate, has good assembly performance, simple structure, and easy disassembly. And it is low cost and high efficiency, and has a one-button control switch function and an anti-reversal self-locking function. The present invention is easy to process other parts, thereby reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0014] See also Figure 1 to Figure 3 The snap cover 1 of this embodiment is mounted on the flywheel 3 and fixed by screws 2, and the dial 4 is embedded in the flywheel 3 and connected as a whole by screws 17. The snap cover 1 is installed in the central hole of the outer cover 9, and a circle of gear ring 12 is provided on the inner wall of the bottom of the central hole of the outer cover 9. The driving wheel 5 is a two-layer structure, with a gear 10 at the bottom and an arc-shaped tooth piece 11 at the top. Similar to the S shape, a pair of blunt teeth matching the gear ring 12 on the outer cover 9 are provided at symmetrical positions outside the arc. The driving wheel 5 is mounted on the central axis of the dial 4, and the blunt teeth on the tooth piece 11 mesh with the gear ring 12 on the outer cover 9. Two small cylinders 13 are provided on the dial 4, and an arc groove 14 matching the small cylinder is provided on the tooth piece 11, and the small cylinder 13 is embedded in the arc groove 14. The dial 4 drives the driving wheel 5 to rotate through the small cylinder 13 and the arc groove 14. The bottom of the driving wheel 5 is provided with a right switch piece 6 and a left switch piece 8. A rack 16 is provided on one side edge of the right switch piece 6 and the left switch piece 8. The rack 16 is meshed with a gear 10 at the bottom of the driving wheel 5. A washer 7 is provided at the end of the central axis of the dial to prevent the driving wheel 5, the right switch piece 6, and the left switch piece 8 from falling off. A lock tongue 15 is provided at the end of the right switch piece 6 and the left switch piece 8. The lock tongue 15 can extend out of the outer cover 9 and move inside and outside.

[0015] When the cover 1 is rotated to rotate the dial 4 through the flywheel 3, the small cylinder 13 on the dial 4 drives the arc groove 14 to rotate, and the pair of teeth on the toothed plate 11 that match the toothed ring 12 on the outer cover 9 are deformed inwards after being stressed, and can be disengaged from the toothed ring 12 to achieve rotation. As a result, the gear 10 at the bottom of the driving wheel 5 rotates, and the gear 10 drives the rack 16 on the right switch plate 6 and the left switch plate 8, so that the lock tongue 15 on the right switch plate 6 and the left switch plate 8 extends outwards and is stuck on the relevant matching parts to achieve the locked state. On the contrary, it shrinks inwards to achieve the open state.

[0016] Due to the two-layer structure of the driving wheel 5, the arc-shaped S-shaped tooth piece 11 cooperates with the tooth ring 12 of the outer cover 9 to play an anti-reversal function, thereby ensuring that the right switch piece 6 and the left switch piece 8 cannot move by themselves without external force, achieving self-locking, thereby increasing the safety of the structure.

[0017] This embodiment has a one-button switch function. The matching structure of the toothed plate 11 of the driving wheel 5 and the toothed ring 12 on the outer cover 9 has an anti-reversal self-locking function. Only when the cover is turned can the right switch plate 6 and the left switch plate 8 be driven to move in a plane, thereby ensuring that the right switch plate 6 and the left switch plate 8 cannot move by themselves. The safety of the structure is increased. This embodiment has low precision requirements for other components, thereby reducing production costs, improving production efficiency, and increasing safety and stability.
