Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 2-12, the present invention provides a technical solution:
the top penetrating cover with the directional tearing function comprises a cover body 1, wherein a positioning portion used for placing a force application portion 3 and a tearing portion connected with the positioning portion are arranged on a top surface 2 of the cover body 1, the force application portion is in multi-point contact with the positioning portion when placed in the positioning portion, the force application portion is directionally moved towards the tearing portion under the action of opposite puncturing forces in the puncturing process until the force application portion is in contact with the tearing portion, and the tearing portion is torn under the stress.
The top surface 2 is provided with an inwards concave fixed through hole 7, a top through structure 8 consisting of a positioning part and a tearing part is hermetically connected to the bottom end of the fixed through hole 7, and the joint of the inner wall of the fixed through hole 7 and the tearing part is set as a strength weakening part 9. The fixed perforations 7 may be arranged in a conventional manner to be concave on the top surface 2, but it is not excluded that they may also be arranged to be convex on the top surface 2.
In the embodiment, the positioning part is provided with a plurality of positioning bulges 5 arranged around the inner layer of the top-through center 4, and the tearing part is provided with a plurality of tearing bulges 6 arranged around the outer layer of the top-through center 4. The distance from the positioning projection 5 to the piercing center 4 is smaller than the distance from the piercing center 4 to the tearing projection 6, so that the piercing cover can be slid directionally relative to the force application part 3. The positioning projections 5 jointly interact with the force application part 3, so that the top-through cover slides directionally relative to the force application part 3.
The 3 edge chamfers of force application portion, under the initial condition, a plurality of location archs 5 all contact with the chamfer department of force application portion 3, and the puncture in-process, under the effect of puncture force in opposite directions, whole top is worn the lid and is slided towards the position that deviates from and tears arch 6, until tearing arch 6 and contact force application portion 3. For a conventional pouring bucket, the piercing force is derived from the bucket and the water's own weight. The chamfer of the force application part 3 is a fillet or an inclined plane, and when the force application part 3 just starts to contact with the positioning part, the positioning bulge 5 contacts with the chamfer of the edge of the force application part 3.
Preferably, a reinforcing rib 10 is provided on the side opposite to the strength reducing portion 9. The reinforcing ribs 10 are arranged, so that the strength of the joint of the reinforcing ribs 10 is higher than that of the strength weakening part 9, the strength weakening part 9 is broken first, and the top penetrating structure 8 is prevented from being completely separated from the cover body 1 and entering water in the water bucket.
Preferably, the outer end of the tearing protrusion 6 on the tearing portion extends to contact with the inner wall of the fixed perforation 7. The tearing then starts from the contact of the tearing projections 6 with the fixed perforations 7. When the tearing bulge 6 contacts with the inner wall of the fixed perforation 7, when the top-through structure 8 acts with the force application part 3, the force received by the strength weakening part 9 is larger than the force on the opposite side of the strength weakening part 9, because the force received by the tearing bulge 6 and the positioning bulge 5 is the same, and the force application part 3 is deviated to the side of the strength weakening part 9, so the distance from the strength weakening part 9 to the acting center of the force application part 3 is longer than the distance from the opposite side of the strength weakening part 9 to the acting center of the force application part 3, and the force received by the strength weakening part 9 is larger according to the relationship between the force and the arm of force, so the top-through structure is broken first.
Preferably, the positioning protrusion 5 and the tearing protrusion 6 are both provided with an inclined surface 13 for guiding, and the top of the inclined surface 13 is provided with an arc 14. Set up inclined plane 13 and circular arc 14 and make this top wear the lid can be applicable to the clever core size of different specification models on the market, still help the top to wear the lid and slide on force application portion 3, and the slip on the 14 sections of circular arc makes force application portion 3 when beginning to act on, and the chamfer of force application portion 3 all contacts with the 14 sections of circular arc of a plurality of location archs 5, can not appear the top and wear the lid can not be on force application portion 3 gliding condition.
At least three positioning protrusions 5 are provided around the center 4 so as to ensure that the urging portion 3 is oriented to move toward the tearing protrusion 6. The number of the positioning projections 5 is not limited to an upper limit in theory, and the number of the positioning projections 5 is generally determined according to the size of the lid body 1. The tearing bulge 6 and the top penetrating center 4 form a straight line, and the plurality of positioning bulges 5 enable the force application part 3 to directionally slide and be arranged on two sides of the straight line. The locating protrusions 5 can be symmetrically arranged on two sides of a straight line and can also be asymmetrically arranged, in order to balance the stress of the force application portion 3, the locating protrusions are symmetrically arranged under most conditions, so that the force application portion 3 can be effectively prevented from sliding towards two sides, the force application portion 3 is promoted to slide towards the tearing protrusion 6 side, the best tearing effect is achieved, the number of the locating protrusions 5 in actual production is not too many, the processing cost is increased too much, and the material waste is caused.
In the embodiment, the positioning projections 5 are provided in seven, wherein the positioning projections 5 are not arranged uniformly, but the distances between the positioning projections 5 become closer as they are farther from the tearing projections 6. This also helps the urging portion 3 to slide toward the tearing projection 6 under the pressure of the lid body 1. In the experiment, the number of the positioning projections 5 is three, and the number of the tearing projections 6 is four, that is, 4 points.
Preferably, the distance from the center 4 to each positioning protrusion 5 is equal. The plurality of positioning bulges 5 form a ring, when the force application part 3 just contacts, all the positioning bulges 5 can bear force, wherein, a slidable channel of the force application part 3 is reserved near the tearing bulge 6, so the positioning bulges 5 are not arranged between the top penetrating center 4 and the tearing bulge 6, the surface of each positioning bulge 5 and the tearing bulge 6 facing the top penetrating center 4 is an inclined surface, and the tearing bulge 6 slides towards the side close to the force application part 3 when the force application part 3 and the cover body 1 are mutually extruded.
The plane of the top-through structure 8 can be parallel to the top surface 2, or the top-through structure 8 can be set to have a certain inclination angle, and the tearing bulge 6 inclines to the side far away from the top surface 2.
In the embodiment, the force application part 3 smoothly acts on the top perforation structure 8 and pushes the top perforation structure 8 away from the fixed perforation hole 7. The laboratory takes the top-through cover of the invention as a 'modified top-through structure', the top-through cover without the positioning protrusion 5 and the tearing protrusion 6 is an 'original top-through structure', and a comparison experiment is carried out, in the experiment, the force for tearing the top-through structure 8 from the positioning hole 7 is just called the top-through force, the numbers 1# and 2# and 17# and the like are numbers of debugging products in the laboratory, the top-through force is detected by a top-through force tester, and the unit of the top-through force is Newton, as shown in the following table:
modifying the cover body of the top penetrating structure: the 10 data for # 1 pull-through force are: 142. 141, 145, 139, 130, 142, 135, 144, 129, 135, the maximum value in this group of data being 145, the minimum value being 129, the deviation value being 16 (difference between maximum and minimum value), the average value being 138.2.
Cover body of original top-through structure: the 10 data for # 1 pull-through force are: 158. 167, 168, 161, 163, 177, 196, 163, 168, the maximum value in this group of data was 196, the minimum value was 158, the deviation value was 38, and the average value was 168.9.
From the above data it can be derived: the lid that the structure was worn on the modification top received the top and worn the power average value less than the original lid that the structure was worn on the top received the top and worn the power average value, and this demonstrates that this application top is worn the lid and is changeed the top and is worn, and the impact force to clever core is corresponding to be reduced, has played the effect of protection clever core. In addition, the power deviation value is worn on the top that the lid that the structure was worn on the modification received is less than original structure far away, so this application top is worn the lid and is received the power of wearing on the top more stable, and the required power of the lid is worn on every turn very stable, when installation bottled water, relies on the gravity of cask and inside water just to accomplish the work of wearing on the top when installation bottled water at every turn, does not need the user additionally to exert force on the cask, has promoted user experience.
In the embodiment, the tearing protrusion 6 protrudes to a height D, the positioning protrusion 5 protrudes to a height E, and the fixed perforation 7 has a depth F, 0< D < F, 0< E < F, and E < D. The protruding height of the positioning bulge 5 and the tearing bulge 6 is not more than the top surface 2 of the cover body 1, if the height exceeds the height, the transportation of barreled water can be affected, the impact between the base of the smart core of the water dispenser can be caused, the base of the smart core can be damaged, and the damage of the positioning bulge 5 and the tearing bulge 6 can be caused.
In the embodiment, the height of the cover 1 is C, 0< F < C. All will set up on lid 1 and decide perforation 7, decide perforation 7 too deeply can cause and decide perforation 7 to damage, perhaps application of force portion 3 is too little, and when the installation bottled water, application of force portion 3 can not contact top throughout and wear structure 8, can't accomplish subsequent work, this relational expression is in order to cover the fenestrate degree of depth of equal size lid top, can practice thrift the processing raw materials simultaneously.
In the embodiment, the outer diameter of the cap opening portion of the cap body 1 is a, the inner diameter of the fixed through hole 7 on the top surface 2 side is B, and 0< B < 0.75A. The volume of different bottled water is different, and the lid 1 that is equipped with also has the difference, still needs to cooperate different water dispensers simultaneously, and under general condition, the clever core size change in the water dispenser can not be too big, and the fixed perforation 7 will be fit for the clever core of multiple water dispenser, so the internal diameter of the top surface 2 side of fixed perforation 7 needs size restriction.
A bucket comprises a bucket body 12 and a top penetrating cover, wherein the bucket body is provided with a bucket opening part, and the top penetrating cover is in sealing fit with the bucket opening part. The outside of the cover body 1 is provided with anti-skid lines 11. Generally, the lid 1 is screwed to the barrel 12, and the side surface of the lid 1 is provided with anti-slip threads 11 for screwing the lid 1 to the barrel 12. Wherein, antislip line 11 is the antislip strip of vertical bar shape, and when staving 12 can also use and lid 1 can not use, only need with lid 1 trade can, the most convenient dismantlement just satisfies lid 1 and staving 12 can be complete the combination be in the same place, and the optimal mode is through threaded connection between body 1 and the staving 12.
In an embodiment, the top perforation structure 8 at the bottom of the fixed perforation 7 may be configured in a circular shape. The top penetrating structure 8 can be arranged in a rectangular shape, a triangular shape, etc., wherein the hole formed by the top penetrating structure 8 does not prevent the top penetrating structure 8 of the force application part 3 from being torn and entering the water barrel 12.
After the positioning bulge 5 and the tearing bulge 6 are arranged on the cover body 1, when the barreled water is installed, the force application part 3 slides to the tearing bulge 6 from the top penetrating center 4, and the top penetrating structure 8 is jacked out of the fixed penetrating hole 7 at the tearing bulge 6. Because the force application part 3 only slides to one direction, compared with the cover body 1 which is not provided with the positioning bulge 5 and the tearing bulge 6, the top penetrating force is more stable, and the bending and breaking conditions of the smart core when the barreled water is used are avoided.
Set up location arch 5 and tear behind protruding 6 structure on lid 1, can increase the wall thickness that structure 8 is worn to top on the lid 1 and place, produce the defect when having avoided moulding plastics, get rid of the later stage completely and produce the condition of leaking because structure 8 is too thin is worn to top.
