Place, including the spiral cover 3 with diversion trench and the measuring cup 2 for being located on diversion trench and being screwed with spiral cover 3.
Figure 4, it can be seen that the upper surface of container 1 is equipped with circular opening between two parties, the outer of the opening is upwardly extended
Forming the first lug boss, the centre of first lug boss is the first intercommunicating pore 12 being connected to the inner cavity of container 1, described first
The first external screw thread 11 is provided on the outer wall of lug boss, the first lug boss where the lower section of the first external screw thread 11 is equipped with limit
Portion, the limiting section are made of first gear tooth 13a, the second gear tooth 13b of gap distribution.The number of limiting section described in the present embodiment
Amount is two, is symmetrically distributed in the two sides of the first lug boss.Being rotated clockwise when screwing of normal condition screwed lid 3, spiral cover 3
Release is to rotate counterclockwise, and first gear tooth 13a is located at the front position clockwise of second gear tooth 13b in the present embodiment, therefore
First gear tooth 13a is designed to up-narrow and down-wide trapezium structure (isosceles trapezoidal structure is preferred) when design, so that first gear tooth 13a
The third gear tooth 38 that does not influence on spiral cover 3 of two sides cross.Second gear tooth 13b is designed to up-narrow and down-wide right-angled trapezium knot
Structure, vertical plane is close to the side first gear tooth 13a, to stop third gear tooth 38 caused by loosening because of spiral cover 3 to rotate counterclockwise,
Guarantee that third gear tooth 38 is in the gap between first gear tooth 13a, second gear tooth 13b, avoids the rotation occurred in transportational process
Lid 3 unclamps problem.
As shown in connection with fig. 5, the spiral cover 3 includes the spiral cover main body 31 of middle part hollow out, the lower end tool of the spiral cover main body 31
There is molding evagination lip 32 in conjunction, the upper end of the spiral cover main body 31 has molding second lug boss in conjunction,
It is provided with the second external screw thread 34 on the second lug boss, screws use for measuring cup 2.It is set in the middle part hollow part of spiral cover main body 31
There is diversion trench 35 (non-to be centrally located).The upper surface of the second lug boss is stretched out in the upper end of diversion trench 35；Outside the lower end of diversion trench 35
Wall and the inner wall of spiral cover main body 31 are fixedly linked, and are in closed state, diversion trench 35 and the first intercommunicating pore 12 are connected, liquid flow
Enter to diversion trench 35.The medial surface of spiral cover main body 31 be equipped with the first internal screw thread, match with the first external screw thread, realize spiral cover 3 and
Threaded connection between first lug boss.The first lug boss is inserted into what diversion trench 35 was formed with spiral cover main body 31 in the present embodiment
In cavity, and with the first internal thread locking.
As shown in figure 9, several third gear teeth 38 being tiltedly installed on the medial surface of evagination lip 32, the third gear
38 equidistant interval of tooth is arranged on the medial surface on outer convex lip side 32.After spiral cover 3 is tightened on the first lug boss, third gear tooth 38
First gear tooth 13a can be embedded in be located between second gear tooth 13b, by the design of above-mentioned gear tooth, with enhance spiral cover 3 screw it is secured
Property, spiral cover 3 and then unclamps when avoiding unscrewing measuring cup 2.
Third gear tooth 38 is arranged on the medial surface on outer convex lip side 32, and structure is in isosceles ladder as first gear tooth 13a
Shape structure.Facilitate the rotation of spiral cover 3.The joining place of spiral cover main body 31 and diversion trench 35 is bank socket part 36, the bank socket part 36 from
Upper lower relative aperture is gradually reduced.The top of second lug boss be equipped be connected with the second external screw thread 34 screw ring 37, it is described to screw
The outwardly convex distance of ring 37 is greater than the second external screw thread 34 can when it is torqued-up on measuring cup 2 together with the second external screw thread 34
Clamping measuring cup 2.
As shown in connection with fig. 5, measuring cup 2 includes cup cover 21, and the cover mouth of cup cover 21 is connected with the upper end of cylinder 23, under cylinder 23
End is equipped with sealing ring 26, and cup cover 21 and the joining place periphery of cylinder 23 are equipped with retaining ring 24, and the inner wall of the retaining ring 24 is equipped with
Second internal screw thread 27 compatible with the second external screw thread 34, and the terminal end path tapering width of the second internal screw thread 27 are realized
With the clamping for screwing ring 37.Above-mentioned cup cover 21, cylinder 23, retaining ring 24 are integrally formed.It is equipped with to increase in the periphery of cup cover 21 and rub
The Vertical texture 1 for wiping power, the Vertical texture 2 22 that increase frictional force is equipped on the outer surface of retaining ring 24 are (above-mentioned vertical
Texture 1, Vertical texture 2 22 can be collectively referred to as Vertical texture).
When installation, 3 first choice of spiral cover is tightened on the first lug boss, until third gear tooth 38 is in first gear tooth 13a, second
It keeps off in the gap between tooth 13b.Then measuring cup 2 is screwed, when the lower end surface of retaining ring 24 and taking in 31 upper end of spiral cover main body
Junction 33 contacts, at this point, sealing ring 26 and bank socket part 36 are in impaction state, screw ring 37 and the second external screw thread 34 is in close
Fit-state, to realize the fixation of measuring cup 2.
Lid by above-mentioned design can effectively be mounted on the opening of container 1, and ensure lid installation after
Fastness is avoided because lid loosens problem caused by jolting.
Embodiment of above is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill
The people of art understands the content of the utility model and is implemented, and does not limit the protection scope of the present invention, and all
According to the equivalent change or modification that the spirit of the present invention is substantially done, should all cover within the protection scope of the present utility model.
