Description

Telescopic funnel

Technical Field

The utility model relates to a funnel specifically is a flexible funnel.

Background

Funnels are cylindrical objects used as containers for liquids and powders to be injected into small inlets, the small tubular part of the mouth of the funnel can be of different lengths, funnels are usually made of stainless steel or plastic, but paper funnels are sometimes used for difficult to clean substances such as engine oil, some funnels are provided with controllable valves at the mouth to allow the user to control the rate of flow of the fluid, funnels are commonly used in kitchens; the funnel can also be found in a laboratory, and sometimes filter paper is used for filtering chemical substances such as crystals; the traditional funnel has no telescopic function, and when the funnel needs to be stored after being used, the funnel occupies a larger space due to a larger appearance, so that the problem of space resource waste is caused; there is therefore a need for improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a telescopic funnel which can realize the telescopic function and can be folded when the funnel is not used, thereby avoiding occupying a large amount of space when being stored; therefore, a telescopic funnel has been proposed to address the above problems.

The utility model discloses a following technical scheme of purpose accessible realizes:

the telescopic funnel comprises a funnel pipeline; the top end of the funnel pipeline is fixedly connected with a main funnel; an inner layer funnel is sleeved on the outer side of the main funnel, and the main funnel is movably connected with the inner layer funnel; the outer side of the inner layer funnel is sleeved with the middle layer funnel, and the inner layer funnel is movably connected with the middle layer funnel; the outer layer funnel is sleeved on the outer side of the middle layer funnel, and the middle layer funnel is movably connected with the outer layer funnel; the top ends of the outer side walls of the main funnel, the inner funnel and the middle funnel are fixedly connected with outer wall convex rings; and inner wall convex rings are fixedly connected to the bottom ends of the inner side walls of the inner layer funnel, the middle layer funnel and the outer layer funnel.

Preferably, a first transverse strip is fixedly connected to one side of the top end of the outer layer funnel, and one end, far away from the outer layer funnel, of the first transverse strip extends to the top of the middle layer funnel; a second transverse strip is fixedly connected to the rear side of the top end of the middle layer funnel, and one end, far away from the middle layer funnel, of the second transverse strip extends to the top of the inner layer funnel; one side on inlayer funnel top is consolidated has the horizontal strip of third, and the one end that the inlayer funnel was kept away from to the horizontal strip of third extends to the top of main funnel.

The utility model has the following substantive characteristics and progress:

1. the utility model discloses a structural design of main funnel, inlayer funnel, middle level funnel, outer funnel, inner wall bulge loop and outer wall bulge loop for flexible function can be realized to this flexible funnel, and when the parking use, can fold up it, avoids can occupying a large amount of spaces when depositing, thereby causes the condition of space resources waste to take place.

2. The utility model discloses a structural design of horizontal strip of first horizontal strip, second and third for this structure can avoid this flexible funnel after the folding, and inlayer funnel, middle level funnel and outer funnel landing downwards can appear, thereby lead to taking place with the condition that this flexible funnel drops completely, has played spacing effect.

Detailed Description

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

Examples 1-5, which include a funnel tube 1; the top end of the funnel pipeline 1 is fixedly connected with a main funnel 2; the method is characterized in that: an inner layer funnel 3 is sleeved on the outer side of the main funnel 2, and the main funnel 2 is movably connected with the inner layer funnel 3; the outer side of the inner layer funnel 3 is sleeved with a middle layer funnel 4, and the inner layer funnel 3 is movably connected with the middle layer funnel 4; the outer layer funnel 5 is sleeved on the outer side of the middle layer funnel 4, and the middle layer funnel 4 is movably connected with the outer layer funnel 5; the top ends of the outer side walls of the main funnel 2, the inner funnel 3 and the middle funnel 4 are fixedly connected with an outer wall convex ring 7; the bottom ends of the inner side walls of the inner layer funnel 3, the middle layer funnel 4 and the outer layer funnel 5 are fixedly connected with an inner wall convex ring 6; during operation, when the telescopic funnel is opened, the inner wall convex ring 6 can be extruded with the outer wall convex ring 7, then the inner wall convex ring 6 moves to the upper part of the outer wall convex ring 7, and the outer wall convex ring 7 can support the inner wall convex ring 6, so that the situation that the inner layer funnel 3, the middle layer funnel 4 and the outer layer funnel 5 can slide downwards after being completely stretched is avoided.

As an embodiment of the present invention, a first transverse strip 8 is fixed to one side of the top end of the outer funnel 5, and one end of the first transverse strip 8 away from the outer funnel 5 extends to the top of the middle funnel 4; a second transverse strip 9 is fixedly connected to the rear side of the top end of the middle layer funnel 4, and one end, far away from the middle layer funnel 4, of the second transverse strip 9 extends to the top of the inner layer funnel 3; a third transverse strip 10 is fixedly connected to one side of the top end of the inner layer funnel 3, and one end, far away from the inner layer funnel 3, of the third transverse strip 10 extends to the top of the main funnel 2; during operation, when the telescopic funnel is folded, the first transverse strip 8, the second transverse strip 9 and the third transverse strip 10 can prevent the inner funnel 3, the middle funnel 4 and the outer funnel 5 from sliding downwards after the telescopic funnel is folded, so that the telescopic funnel completely falls off, and a limiting effect is achieved.

The working principle is as follows: when the telescopic funnel is needed, the inner funnel 3, the middle funnel 4 and the outer funnel 5 slide upwards, the inner wall convex ring 6 can be extruded with the outer wall convex ring 7 in the sliding process, and then the inner wall convex ring 6 moves to the upper part of the outer wall convex ring 7; in the process of folding the telescopic funnel, the first transverse strip 8, the second transverse strip 9 and the third transverse strip 10 can prevent the inner funnel 3, the middle funnel 4 and the outer funnel 5 from sliding downwards after the telescopic funnel is folded, so that the telescopic funnel completely falls off, and the limiting effect is achieved; and then this flexible funnel can realize flexible function to when stopping using, can fold up it, avoid can occupying a large amount of spaces when depositing, thereby cause the condition of space resource waste to take place.
