Description

Nesting-prevention suction nozzle cover

The technical field is as follows:

the utility model belongs to the technical field of the seal closure structure, especially, relate to a prevent intussusception suction nozzle lid.

Background art:

the suction nozzle cover is commonly used on a food standing bag and is usually in the shape of a cap with an internal thread, and the outer surface of the suction nozzle cover is mainly provided with an external straight tooth for increasing friction force, so that the suction nozzle cover can be conveniently screwed and opened. At present, current suction nozzle lid is injection moulding usually, the surface of its lid covers outer straight tooth completely, after the completion of moulding plastics, a large amount of lids pile up easy two liang of cup joints of in-process, outer straight tooth is deepened inside another lid easily promptly, produce interference fit with the internal thread of lid inner wall, lead to two very difficult quilt after the intussusception of should pasting to be separated, and because the suction nozzle lid volume that is used for the food suction nozzle is less, even the worker holds between the fingers and carry out the split, because the gripping point is less, also very arduous during specific operation, waste a large amount of manpower and materials on the production line, and the defective percentage is higher.

The invention content is as follows:

in view of the above-mentioned prior art not enough, an object of the utility model is to provide an prevent intussusception suction nozzle lid, increase anti-sticking ring width prevents the suction nozzle lid intussusception, improves product quality and production efficiency.

For solving the above technical problem, the utility model discloses the technical scheme who adopts is:

the utility model relates to a prevent intussusception suction nozzle lid has block and theftproof ring, the block surface covers has outer straight tooth, forms the glossy snap ring of preventing between outer straight tooth upper end and the block top, the width of preventing the snap ring is not less than the width of theftproof ring.

The utility model discloses a cap lower extreme has the linking ring that leans out, and links up the ring and be connected with the anti-theft ring through a plurality of bridgepoints.

The utility model discloses an it has the cusp to join up the inboard branch cloth of ring.

The utility model discloses a linking ring below is equipped with two at least downwardly extending's ratchet, and the theftproof ring corresponds the ratchet position and is equipped with and keeps away the dead slot.

The ratchet of the utility model is in the shape of a right trapezoid.

The utility model discloses a plurality of trench have still been seted up to the theftproof ring lower extreme, make the tip form a plurality of elastic pressing pieces under the theftproof ring.

The beneficial effects of the utility model are that: to traditional block structure, the utility model discloses the coverage of the outer straight tooth of reduction, increase anti-sticking ring width, inside the outer straight tooth infiltration block when avoiding two blocks to telescope each other, can solve the block intussusception problem, improve production efficiency and product quality. In addition, the ratchet structure and the elastic pressing sheet structure of the anti-theft ring are combined, the dismounting structure is stable, the cap and the assembling port can be mounted and connected conveniently, the cap can be unscrewed easily, and the operation is convenient and labor-saving.

Description of the drawings:

fig. 1 is a schematic side view of the structure of the present invention;

fig. 2 is a schematic view of the bottom view of the present invention;

fig. 3 is a schematic view of the structure of the present invention in case of intussusception.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, the utility model relates to a prevent intussusception suction nozzle lid, block 1 and anti-theft ring 2 have, block 1 inner wall has the internal thread, block 1 outer surface covers has outer straight tooth 11, form glossy anti-sticking ring 12 between outer straight tooth 11 upper end and the block 1 top, the width of anti-sticking ring 12 is not less than anti-theft ring 2's width, make anti-sticking ring 12 have sufficient width, when anti-sticking ring 12 gets into the inner wall of another block 1, receive the internal thread to block, outer straight tooth 11 can't get into in block 1, can effectively avoid two blocks to intussuscept each other.

The cap 1 lower extreme has the linking ring 3 that leans out, and links up ring 3 and be connected with anti-theft ring 2 through a plurality of bridge points 21, links up ring 3 and can laminate with the suction nozzle mouth, and 3 inboard distributions of linking ring have cusp point 31, can strengthen linking ring 3's atress, and when twisting the cap 1, cusp point 31 and suction nozzle mouth friction, the initial of twisting has certain damping effect, can avoid being opened by the mistake.

At least two ratchets 32 extending downwards are arranged below the connecting ring 3, the anti-theft ring 2 is provided with a clearance groove 20 corresponding to the ratchets 32, and the ratchets 32 are in a right-angled trapezoid shape, so that the cap 1 and the anti-theft ring 2 can be separated from each other only from one direction. The gap between the right-angle edge of the ratchet 32 and the right-angle edge of the clearance groove 20 is smaller than 1mm, and when the cap 1 and the anti-theft ring 2 are screwed into the nozzle opening together, the ratchet 32 can prevent the bridge point 21 from being broken under stress; when the cap is unscrewed, the inclined edge of the ratchet 32 advances toward the inclined edge of the clearance groove 20, and the ratchet 32 is not limited by the clearance groove 20, so that the bridge point 21 can be broken to separate the cap 1 from the antitheft ring 2.

In order to avoid the accompanying rotation of the anti-theft ring 2 when the cap 1 is unscrewed, the lower end of the anti-theft ring 2 is further provided with a plurality of groove positions, the lower end part of the anti-theft ring 2 forms a plurality of elastic pressing sheets 22, and thus an outward inclined structure is designed at the corresponding position at the lower part of the nozzle, when the cap 1 is screwed and assembled, the anti-theft ring 2 is positioned at the inclined position of the nozzle, as shown in fig. 1, the elastic pressing sheets 22 can press the inclined outer wall of the nozzle, when the cap 1 is unscrewed, the anti-theft ring 2 is tightly attached to the nozzle, so that the reaction force is generated, the cap 1 can be easily broken by screwing, and further, the cap 1 is separated from the anti-theft ring 2.

It should be understood that the technical scope of the present invention is not limited to the content of the specification, and that modifications or changes may be made by those skilled in the art based on the above description, and all such modifications and changes should be within the scope of the appended claims.
