[ Utility model ] content

The utility model aims at overcoming the above-mentioned problem, we provide a manual formula sucking disc, this manual formula sucking disc simple structure, and the user need not to spend the strength of strength when the operation, and is suitable for the crowd extensive.

In order to achieve the above object, the utility model provides a manual formula sucking disc, it is including the cover body and locate the screw sucking disc on the cover body, the top center department of the cover body opens the hole site that has the screw thread post that supplies on the screw sucking disc to pass, the top of the cover body be equipped with the knob of screw thread post spiro union, the top of the cover body be equipped with upwards extend and with the spacing seat of knob butt, thereby the knob can rotate for the cover body and make the screw sucking disc inhale tightly or relax.

In one or more embodiments, the knob is provided with a connecting portion with internal threads, the internal threads on the connecting portion are matched with the threaded column, and the knob is made of an ABS material.

In one or more embodiments, the bottom of the knob is provided with an annular connecting portion abutting against the limiting seat.

In one or more embodiments, the side surface of the knob is provided with a plurality of convex anti-slip parts, and the top surface of the knob is provided with a convex arched hand-held part.

In one or more embodiments, the cover body and the limiting seat are of an integrally formed structure, and the cover body and the limiting seat are made of PVC materials.

In one or more embodiments, the suction cup body of the screw suction cup comprises an upper layer part and a lower layer part, the upper layer part and the lower layer part are bonded through glue dripping, the upper layer part is TPE, and the lower layer part is TPU.

Compared with the prior art, the utility model the effect that exists is: this manual formula sucking disc's structure is simple relatively, and cost reduces, can improve the market competitiveness of enterprise on like product to during the use, only need can make the sucking disc slowly inhale tightly through rotating the knob, during the dismantlement, also through rotatory knob, convenient to use is applicable to very much less user of some strength.

[ detailed description ] embodiments

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

Referring to fig. 1-4, this embodiment provides a manual sucking disc, which includes a cover body 1 and a screw sucking disc 2 disposed on the cover body 1, a hole for a threaded post 21 on the screw sucking disc 2 to pass through is formed at the center of the top of the cover body 1, a knob 3 screwed with the threaded post 21 is disposed at the top of the cover body 1, a limiting seat 4 extending upward and abutting against the knob 3 is disposed at the top of the cover body 1, the knob 3 can rotate relative to the cover body 1 to tightly or loosely suck the screw sucking disc 2, due to the fact that the limiting seat 4 abuts against the knob 3, when the knob 3 rotates, the sucking disc 2 will be pushed outward under the action of the internal threads of the knob 3 and the external threads of the threaded post 21, during the pushing-out process, the air in the sucking disc is discharged, when the user rotates the knob 3 to a position difficult to rotate, i.e. the air in the sucking disc is substantially evacuated, and, when the user needs to dismantle, the reverse direction is rotated knob 3 and the sucking disc is retrieved can, and the user only needs to rotate knob 3 when fixing or dismantling the sucking disc in the operation, therefore the operation is very simple, need not to spend the vigorous operation.

Be equipped with on the knob 3 and take internal thread connecting portion 5, internal thread on this connecting portion 5 with the cooperation of screw thread post 21, knob 3 is made for the ABS material, connecting portion 5 is made for copper injection molding, and is concrete, including inside copper thread portion and outside ABS material, copper thread portion connecting thread post 21 is difficult for appearing the thread problem of sliding, and connecting portion 5 and knob 3 are through injection moulding.

The bottom of knob 3 be equipped with the annular connecting portion 6 of spacing seat 4 butt, knob 3 passes through annular connecting portion 6 and the contact of spacing seat 4, can reduce frictional force as far as possible, and the user of being convenient for rotates knob 3.

The side of knob 3 is equipped with a plurality of bellied antiskid 7, and antiskid 7 strengthens anti-skidding effect when the user is at rotatory knob 3, and the top surface of knob 3 is equipped with handheld portion 8 of bellied arch, when knob 3 can not satisfy the rotatory demand of user, can rotate through handheld portion 8 of centre gripping arch.

The cover body 1 and the limiting seat 4 are of an integrally formed structure, the cover body 1 and the limiting seat 4 are made of PVC materials, the ABS materials are common materials in the market and are easy to purchase, and the ABS materials have the advantages of heat resistance, corrosion resistance and high surface hardness.

The sucker body 22 of the screw sucker 2 comprises an upper layer part 221 and a lower layer part 222, the upper layer part 221 and the lower layer part 222 are adhered through glue dripping, the upper layer part 221 is TPE, the lower layer part 222 is TPU, the TPE material has the advantages of high elasticity, high strength and high resilience, the TPU material has the advantages of high tension, high tensile force, toughness and aging resistance, and therefore the sucker body 22 has the advantages of strong sucker bearing capacity and firm suction force,

in addition to the above embodiments, the present invention can also have other embodiments, and the technical solutions formed by equivalent replacement or equivalent transformation are adopted and all fall within the protection scope of the present invention.
