Abstract
The utility model relates to a kind of preventing and draws the barb members dragged, comprise the first component, first component is cylindrical structure, the periphery of the first component is provided with several grooves, second component is extended downwards in the upside of groove, the lower end of second component is connected with the 3rd component, the utility model structure is simple, easy to use, the structure of the 3rd component and arrangement mode can increase the surface of contact thus increase sealing that can prevent from drawing the barb members dragged greatly, arranging of resilient member can make the 3rd component be upspring fast, thus can prevent from drawing when sealing dragging, ensure reliability and the Security of sealing.
Description
Technical field
The utility model relates to a kind of preventing and draws the device dragged, and specifically, relates to a kind of preventing and draws the barb members dragged.
Background technique
At present, the component of reversed acanthoid is usually used in the fields such as Aeronautics and Astronautics, medical treatment, industry, for to seal or other needs prevent from drawing the place of dragging, the component of conventional reversed acanthoid generally comprises equally distributed hangnail, the shape of hangnail is leptosomatic thorn-like, and the elasticity only by material itself after hangnail is depressed is difficult to again reset to the state of originally opening again, when sealing, firmly just can be drawn hauling-out a little, be difficult to firmly seal.
Model utility content
The technical problems to be solved in the utility model is for above deficiency, provide a kind of structure simple, easy to use, can carry out secure seal prevent draw the barb members dragged, can upspring rapidly after hangnail is depressed.
In order to solve above technical problem, the technical solution adopted in the utility model is as follows: a kind of preventing draws the barb members dragged, comprise the first component, first component is cylindrical structure, the periphery of the first component is provided with several grooves, second component is extended downwards in the upside of groove, and the lower end of second component is connected with the 3rd component;
The inner and outer wall of the 3rd component is the curved surface concaved, and curvature is identical, and the bottom of the 3rd component is circular arc, and the length of the bottom of the 3rd component accounts for the 1/6-1/8 of place, bottom circle;
The bottom of groove is provided with resilient member, and the quantity of resilient member is 3, increases highly gradually from top to bottom, and 3 resilient members aspect ratio is from top to bottom 1:1.5:1.7.
Further improvement as technique scheme:
The sectional shape of described resilient member is 3/4 ellipse.
Described several grooves grouping is arranged, and at least can be divided into two groups of settings, and often group groove is arranged in order setting along the axial direction of the first component.
Several groove arrangement curls described or random interval arrangement.
Several grooves described can be symplex structures, also can be non-symmetry structures.
The utility model takes above technological scheme, have the following advantages: the utility model structure is simple, easy to use, the structure of the 3rd component and arrangement mode can increase the surface of contact thus increase sealing that can prevent from drawing the barb members dragged greatly, arranging of resilient member can make the 3rd component be upspring fast, thus can prevent from drawing when sealing dragging, ensure reliability and the Security of sealing.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation that can prevent from drawing the barb members dragged in the utility model embodiment;
Accompanying drawing 2 is structural representations of second component and the 3rd component in the utility model embodiment;
Accompanying drawing 3 be in accompanying drawing 2 A-A to structural representation;
Accompanying drawing 4 is plan views of accompanying drawing 2.
In figure,
1-first component, 2-second component, 3-the 3rd component, 4-groove, 5-resilient member.
Embodiment
Embodiment, as shown in Figure 1, a kind of preventing draws the barb members dragged, comprise the first component 1, first component 1 is cylindrical structure, the periphery of the first component 1 is provided with several grooves 4, the grouping of several grooves 4 is arranged, at least can be divided into two groups of settings, often group groove 4 is arranged in order setting along the axial direction of the first component 1, the upside of groove 4 extends second component 2 downwards, the lower end of second component 2 is connected with the 3rd component 3, several grooves 4 also can be arranged in helical or random interval arrangement, it can be symplex structure, also can be non-symmetry structure, such arrangement mode can increase the surface of contact thus increase sealing that can prevent from drawing the barb members dragged greatly,
As shown in accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, the inner and outer wall of the 3rd component 3 is the curved surface concaved, curvature is identical, the bottom of the 3rd component 3 is circular arc, the length of the bottom of the 3rd component 3 accounts for the 1/6-1/8 of place, bottom circle, and such structure can increase the surface of contact thus increase sealing that can prevent from drawing the barb members dragged greatly;
The bottom of groove 4 is provided with resilient member 5, the quantity of resilient member 5 is 3, increase highly gradually from top to bottom, 3 resilient members 5 aspect ratio is from top to bottom 1:1.5:1.7, the shape of resilient member 5 is 3/4 ellipse, arranging of resilient member 5 can make the 3rd component 3 be upspring fast, thus can prevent from drawing when sealing dragging, and ensures reliability and the Security of sealing.
The utility model can be used for the fields such as Aeronautics and Astronautics, medical treatment, industry, such as stitching thread etc. medically, above display and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
