Abstract

The utility model relates to a suction cup which is mainly an object capable of being fixed by using atmospheric pressure difference, particularly to a suction cup which is made of plastic materials and is used for work or families, and the suction cup comprises a plastic body. The utility model is characterized in that an annular groove which surrounds the center of the plastic body is arranged at the bag part of the plastic body. Through the structure that the annular groove which surrounds the center of the plastic body is arranged at the bag part of the plastic body, the volume of the bag part of the plastic body can be enlarged when the bag part of the plastic body is used, so the utility model reduces atmospheric pressure in the bag part, enhances the suction force of the suction cup, and has the advantages of simple structure, large suction force, long service life and low manufacture cost. Meanwhile, because the U-shaped groove has large deflection, the operation of stretching the suction cup is laborsaving.

Description

Sucker

Technical field

The utility model sucker relates generally to a kind of object that utilizes atm difference to fix, and especially relates to work that plastic material makes or home-use sucker.

Background technique

People are not strange to sucker.It is very difficult sometimes to fix article on a smooth plane, has had the sucker problem to be readily solved.But existing sucker exists a lot of defectives.At first, the suction of sucker is little.In order to address this problem, people are general, and the method that adopts is under the situation of conditions permit, and according to the field of employment or the condition of sucker, that as far as possible sucker is done is bigger, perhaps adopt the big material of senior elasticity, these two kinds of ways all can cause the rising of fabricating cost.Next is to use the life-span short.Repeatedly, under the frequent situation about using,, make to become very short working life, unnecessary expenditure and trouble have been brought to the Consumer undoubtedly because material is aging.

Summary of the invention

The purpose of this utility model provides a kind of sucker of new structure, and it has overcome the defective of the above sucker, and is simple in structure, and suction is big, and the life-span is long, and fabricating cost is low, adapts to the demand in market.

The technical solution of the utility model is a kind of sucker, comprises the plastic cement body, it is characterized in that at described plastic cement body capsule portion, around the center of plastic cement body annular recess is arranged.

Above-mentioned sucker, described annular recess are that several concentric circle grooves are formed.

Above-mentioned sucker, the sectional shape of described groove are " U " shapes.

Above-mentioned sucker, the notch of described groove is positioned at the internal surface of sucker.

Adopt above-mentioned structure, in the capsule portion of plastic cement body, annular recess is arranged around the center of plastic cement body, can make the capsule portion of plastic cement body enlarge its volume in use, reduce the gas pressure intensity in the capsule, increase the suction of sucker, simple in structure, suction is big, and the life-span is long, and fabricating cost is low, because it is " U " shape groove amount of deformation is bigger, very laborsaving during the stretching sucker simultaneously.

Fig. 4 is a partial enlarged drawing shown in Figure 3.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See Fig. 1, Fig. 2, Fig. 3, shown in Figure 4:

Sucker of the present utility model, comprise plastic cement body 1, mainly form by edge section 2, capsule portion 3, afterbody 4, edge section 2 constitutes an airtight cavity with capsule portion 3 with the plane that contacts, its inside and outside pressure reduction that forms utilizes atmospheric pressure fixing in the plane, and will there be certain width edge section 2, be beneficial to guarantee the seal of cavity, afterbody 4 is used for operation, fixing sucking disk and hangs article.

In the capsule portion 3 of plastic cement body 1, annular recess 6 is arranged, see Fig. 1, shown in Figure 3 around the central point 5 of plastic cement body 1.Described annular recess 6 can adopt multiple structure shape, Fig. 1, Figure 3 shows that several concentric circle grooves form, and can be a circular groove, also can be two, or a plurality of, can according to circumstances determine.The sectional shape of described groove 6 is " U " shapes, also can be " V " etc., sees Fig. 3, shown in Figure 4.Structure like this, under situation about not stressing, the space is very little in the groove of groove 6, is being subjected under the external force effect, and the notch 61 of groove 6 opens, becomes big, make space enlargement in the groove, thereby it is very big to make that the interior space of capsule portion 3 of plastic cement body 1 can become, and it is big that the space becomes, and internal pressure diminishes, it is big that inside and outside differential pressure becomes, big thereby the suction of sucker becomes.Because the crushed element of sucker is in elasticity " U " shape part preferably, edge section 2 distortion that seal are very little, thereby guarantee to have enough sealing surfaces, strengthen the endurance of sucker.

Further form, the notch 61 of described groove 6 is positioned at the internal surface of sucker body 1, and just the notch 61 of groove 6 is opened the interior space in capsule portion 3, so more helps capsule portion 3 extending spaces, reduces the gas pressure intensity in the capsule, increases the suction of sucker.

In order to strengthen the intensity of sucker, can make strength bar at the outer surface of the capsule portion 3 of plastic cement body 1.

The utility model adopts above structure, and is simple in structure, and suction is big, and the life-span is long, and fabricating cost is low.

Claims

1, a kind of sucker comprises the plastic cement body, it is characterized in that at described plastic cement body the middle part, around the center of plastic cement body annular recess is arranged.

2, sucker according to claim 1 is characterized in that described annular recess is several concentric circle grooves.

3, sucker according to claim 1 and 2, the shape that it is characterized in that the sectional shape of described groove is " U ".
