Specific embodiment
The cup body that the utility model is selected includes stainless steel water-storing bottle and the bottleneck sticking department 15 for being nested in water-storing bottle bottleneck,
Bottleneck sticking department 15 uses plastic material injection molding；Cup lid uses plastic material injection molding, and cup lid lid is closed to be locked in bottleneck
In portion 15 and water-storing bottle bottleneck, and connected with 15 locking of bottleneck sticking department.
The rear end of cup lid is connected with the rear end of the bottleneck sticking department 15 of cup body by shaft, and is equipped with elastic slice, cup lid lid
It closes when on cup body, elastic slice is compressed, and elastic force is generated, as the external force for opening cup lid；First magnetic storehouse 1 and catching groove 4 are set to cup
Lid front end, 1 inner set magnet of the first magnetic storehouse；Snap close piece 3 and locking device cavity 10 are set to 15 front end of bottleneck sticking department；
It is specific:
The snap close piece 3 is generally round, including presses part 5 and driver plate 6；
The part 5 that presses is annular shape, outside diameter 24mm, interior circular diameter 19mm, thickness 4mm；Latch hook 7, which is set to, to be pressed
5 inside top of part, and press part 5 and be integrally formed, direction is inwardly (towards water-storing bottle)；The catching groove 4 is groove, is set to cup
Outer side of lid face, outward opening；Cup lid front bottom end under catching groove 4 is equipped with an inclined-plane, and latch hook 7 slides into button when Convenient cup cover lower cover
In slot 4；As shown in Figure 1；
The shaft 8 for pressing part 5 or so and being equipped with integrated injection molding, is rotated with bottleneck sticking department 15 by shaft 8 and is connected
It connects；
The driver plate 6 is disk；6 diameter of driver plate matches with round hollowed out area diameter, is embedded in and is positioned at and presses part 5
Annulus hollow portion, and back rotation can be carried out in round hollowed out area along disk circumferential direction；6 back of driver plate is equipped with to water storage
The cylinder 9 that bottle bottle body stretches out, column diameter 11.8mm；Second magnetic storehouse 2 is set on cylinder 9, is inside placed with magnet, can and the
One magnetic storehouse, 1 internal magnet is attracting, and is located at immediately below the first magnetic storehouse 1 of cup lid；Rotating driver plate 6 rotates cylinder 9, drives second
Magnetic storehouse 2 rotates, and causes a deviation from the first magnetic storehouse 1.The rotational angle of driver plate 6 is limited to 45 ~ 90 °, and specific rotational angle can root
According to selecting magnet magnetic force size and cup size to be adjusted, guarantee after rotating, between the first magnetic storehouse 1 and the second magnetic storehouse 2
There is the magnetic force for sucking back the second magnetic storehouse 2 enough.
Cup lid lid is closed in cup body, is formed between the front end region and locking device cavity 10 and bottleneck rim of a cup of cup lid
Gap 11.
The 10 cavity open front of locking device cavity is external forward, while 10 top surface of locking device cavity also is provided with top opening, makes to lock
Only 10 cavity of device cavity can directly contact the bottom surface and gap 11 of cup lid front end region；As shown in Figure 3.
The snap close piece 3 press part 5 and driver plate 6 is set to cavity open front position, whole 3 lower half of snap close piece is most of
It is covered on 10 cavity open front position of locking device cavity, upper half fraction is covered on cup lid front end face, it can make to press the top of part 5
The latch hook 7 in portion can correspond to 4 position of catching groove of cup body.
The shaft 8 for pressing the protrusion of part 5 or so is inserted into preset turn hole on cavity open front or so medial surface, and rotation connects
It connects；Cylinder 9 is inserted into locking device cavity 10, and end is not bonded with 10 inner sidewall of locking device cavity thereafter, and there are for cylinder 9
The gap that (i.e. driver plate 6) moves inward.
5 inside bottom of part that presses stretches out a limited block 12 into locking device cavity 10, the limited block 12 also and
The integrated molding of part 5 is pressed, is shorter in length than cylinder 9, and 12 height of limited block is greater than and presses 5 annulus ring width of part, above inner ring,
Form a blocking inside to driver plate 6；As shown in Figure 1；Ensure that inwardly will not deviate to press part 5 when inwardly pressing driver plate 6,
Energy band dynamic pressure is inwardly pressed together by part 5.
When the second magnetic storehouse 2 is located at the first 1 underface of magnetic storehouse, cylinder 9 up and down it is each stretch out one be integrally formed and
At fixing tongue piece 13, the fixing tongue piece 13 on top protrudes into gap 11, and is tightly attached on the rear wall of cup lid front end region；Under
After the fixing tongue piece 13 in portion protrudes into limited block 12, and it is tightly attached to the rear end face of limited block 12.
12 rear end face of limited block is divide into upper part and lower part region: the fixing tongue piece 13 of lower part is only covered and is touched
Portion region, i.e. fixing 13 height of tongue piece are less than 12 height of limited block；Lower area does not cover contact and locking device cavity 10
There are gaps between side wall, and the elastic device 14 of energy compression rebound is arranged in the gap.When pressing part 5 and being pushed by external force, limit
Position 12 elasticity of compression device of block, after external force is cancelled, elastic device 14 is sprung back, and makes to press the playback of part 5；The elastic device is
Spring or soft rubber block.As shown in Figure 1.
When the utility model is used, when pressing 3 lower end of snap close piece, due to the fixing on the top of the cylinder 9 of driver plate 6
13 front end face of tongue piece heads on the rear wall of cup lid front end region, is based on wraping plate principle, 6 lower end of driver plate, which is limited down, presses, together
When press the limited block 12 of part 5 and head on 13 front end face of fixing tongue piece of lower part, press part 5 limited down by；It is ingenious based on this
Linkage limit, entire 3 lower part of snap close piece is locked out pushings, and based on wraping plate principle, the latch hook 7 for pressing 5 upper end of part cannot
It is detached from catching groove 4, cup lid and cup body locking closure.
When rotating driver plate 6, when cylinder 9 rotates, the fixing tongue piece 13 on top can be with gap 11 be produced, into locking device
In chamber 10；The fixing tongue piece 13 of lower part can be with the rear end face being rotated away from limited block 12；Thus part 5 and driver plate 6 are pressed
Lower end can be pressed down (i.e. 3 lower part of snap close piece can be pressed down), be based on wraping plate principle, the latch hook 7 for pressing 5 upper end of part can be detached from button
Slot 4, cup lid and cup body unlock；At this time using the elastic force of the elastic slice at the shaft of cup lid and cup body rear end, cup lid is flicked.At this time
Due to the first magnetic storehouse 1 as cup lid leaves together, the second magnetic storehouse 2 keeps postrotational position.
When closing cup lid lid, the first magnetic storehouse 1 is combined into original position as cup lid covers together, and latch hook 7 turns back in catching groove 4, at this time
Since magnetic-adsorption acts on, the second magnetic storehouse 2 is adsorbed by the first magnetic storehouse 1, is rotated back to immediately below the first magnetic storehouse 1, i.e., upper and lower part fixes
Tongue piece 13 playbacks, and snap close piece 3 cannot be pressed, cup lid and cup body locking closure.
The utility model advantage is simple and ingenious structure, convenient to use, one-handed performance, and cup is closed and locking one
Step is completed.
