Specific embodiment
It is specific embodiment of the utility model below, and in conjunction with attached drawing, the technical solution of the utility model is made into one
The description of step, but the utility model is not limited to these examples.
As shown in Figures 2 to 4, a kind of to enhance elastic rubber circle, including 21 He of rubber ring ontology for nested mandrel
Elastic force enhanced portion 22 is equipped with the first through hole 23 for axially penetrating through its ontology, 23 inner sidewall of first through hole in the middle part of rubber ring ontology 21
On be uniformly equipped with multiple rubber strips 24,21 lower end of rubber ring ontology is equipped with annular groove 25, uniformly sets in annular groove 25
Have multiple second through-holes 26, elastic force enhanced portion 22 include the fixed ring 27 to match with annular groove 25 and with the second through-hole
26 support columns 28 to match, multiple support columns 28 are uniformly arranged in fixed ring 27, and support column 28 and fixed ring 27 are opposite
Elastic force enhanced portion 22 is fixed on rubber ring ontology 21 by being nested in the second through-hole 26 and annular groove 25 for answering.
The presence of second through-hole 26 can provide bigger elastic space for first through hole 23, insert in first through hole 23
When mandrel, by the squeezing action to the second through-hole 26 during inserting, mandrel can be made to be relatively easy to set and be packed into first
In through-hole 23；After completing suit, elastic force enhanced portion 22 is inserted into the second through-hole 26 and annular groove 25, on the one hand by rubber
The place with gap is tamped on circle ontology 21, on the other hand by 22 upper support column 27 of elastic force enhanced portion to the second through-hole 26
Squeezing action can make the inner sidewall of first through hole 23 squeeze mandrel, increase the withstanding effect power between rubber ring and mandrel,
To increase frictional force between the two, in conjunction with stronger.
The number of rubber strip 24 is equal to the number of the second through-hole 26, and the two misplaces in the radial direction in rubber ring ontology 21
Arrangement, the presence of rubber strip 24 can slow down contact area when mandrel inserting, reduce frictional force when inserting, aspect inserting；
Meanwhile after second is inserted into support column 27 in through-hole 26, the contact area of first through hole 23 inner wall and mandrel can be increased, improve two
Frictional force between person.
The number of second through-hole 26 is two to four.
Fixed ring 27 is hard fixed ring, and support column 28 is rigid support column, and elastic enhanced portion 22 is inserted into rubber ring sheet
Deformation will not be generated after on body 21, is preferably played a supporting role.
Side on rubber ring ontology 21 far from annular groove 25 is equipped with limit concave station 29, and it is logical that limit concave station 29 is located at first
The outside in hole 23, and the two connects.
Second through-hole 26 is located on limit concave station 29 far from the outlet of 25 side of annular groove.
Working principle:
As shown in Figure 1, mandrel generally comprises docking column 1, upper part and lower part are respectively provided with the first positive stop lug boss 12 and the
Two positive stop lug boss 13, it is therefore an objective to rubber ring is fixed on the position between two positive stop lug boss, will there is the second limit on mandrel
There is one end of limit concave station 29, by the compressible sky of the second through-hole 26 on the side insertion rubber ring ontology 21 of position boss 13
Between, mandrel can readily be inserted into first through hole 23, until the first positive stop lug boss 12 mutually agrees with limit concave station 29, so
Elastic force enhanced portion 22 is inserted in the second through-hole 26 and annular groove 25 afterwards, is allowed to agree with completely with rubber ring ontology 21, i.e.,
Complete the assembling of rubber ring and mandrel.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
