Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

In order that those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and specifically The utility model is described in further detail for embodiment.

It refer to Fig. 1 to Fig. 5, the explosive view for the circular plugging device that Fig. 1 is provided by the utility model embodiment；Fig. 2 The profile of the circular plugging device provided by the utility model embodiment；Fig. 3 is the arc length A between two buckles in Fig. 1 Schematic diagram；Fig. 4 is the schematic diagram of the arc length B of buckle in Fig. 1；Fig. 5 is Fig. 1 central posts gap arc length C schematic diagram.

A kind of circular plugging device provided by the utility model, mainly including circular blanking cover button 1 and rubber knob 3, such as Shown in Figure of description 1 and accompanying drawing 2.

Circular blanking cover button 1 has gas dome 11, column 12 and snap ring 13, and circular blanking cover button 1 can be formed in one Structure；Column 12 is located at the lower section of gas dome 11, and axially extends, and column 12 can be regarded as hollow cylinder, hollow cylinder Axis overlapped with the axis of gas dome 11；Snap ring 13 is located at the end of column 12, extends radially and laterally, such as says Shown in bright book accompanying drawing 2, the section of circular blanking cover button 1 is in π shapes.

Rubber knob 3 has limiting section 31, and limiting section 31 is convex, and the internal diameter of limiting section 31 is less than the outer of snap ring 13 Footpath so that position-limiting action is played in the lower surface of limiting section 31 to the upper surface of snap ring 13, and then realizes that limiting section 31 is stuck in snap ring 13 upper surface, to limit the axial movement section of circular blanking cover button 1.

For the circular plugging device of elastic material, column 12 should have certain elastic deformation amount after stress；Filling During matching somebody with somebody, column 12 can stretch into the internal diameter of limiting section 31 to contract certain distance so as to snap ring 13；Once snap ring 13 Through the position of limiting section 31, column 12 recovers to original size immediately, and then realizes that limiting section 31 is stuck in snap ring 13 Upper surface, the purpose in the axial movement section of the circular blanking cover button 1 of limitation is reached.Certainly, sealed for the circle of metal material Block apparatus, the principle expanded with heat and contract with cold can also be used to assemble circular blanking cover button 1 and rubber knob 3, repeated no more herein.

After circular blanking cover button 1 and rubber knob 3 coordinate in place, i.e. upper table of the lower surface of limiting section 31 to snap ring 13 When position-limiting action is played in face, no matter how circular blanking cover button 1 rotates, and is able to ensure that circular blanking cover button 1 and rubber knob 3 Position it is accurate, avoid because circular blanking cover button 1 rotates and caused by site error.

Above-mentioned limiting section 31 is specially the buckle of multiple rounded distributions, as shown in Figure of description 1 to accompanying drawing 4.Snap ring 13 is rounded, multiple rounded distributions of buckle, so as to effectively ensure position-limiting action of the buckle to snap ring 13.

The specially three pieces of arcuation columns, and the column gap arc length C between two pieces of arcuation columns of arbitrary neighborhood of column 12 It is identical；Six size identical buckles are divided into three groups, and are in 120 ° of angles between any two groups of buckles.

In the utility model, column 12 could be arranged to three pieces of independent arcuation columns, as shown in Figure of description 5.Three The rounded distribution of arcuation column of block independence, and the column gap arc length C between two pieces of arcuation columns of arbitrary neighborhood is identical； The buckle of rubber knob 3 sets six, and six size identical buckles are divided into three groups, and is between any two groups of buckles 120 ° of angles, as shown in Figure of description 3 and accompanying drawing 4.

Arc length A in any one group between two buckles is more than or equal to the arc length B and column gap arc length C sums of buckle. That is, A >=B+C；It is arranged such, circular blanking cover button 1 can be installed in place by any angle in 360 ° of horizontal plane, and then Production efficiency is improved, so as to reduce cost, and improves performance reliability.

Circular plugging device of the present utility model, in addition to upper knob 2 and lower knob 4, such as Figure of description 1 and accompanying drawing 2 It is shown.Lower knob 4 is located at the lower section of rubber knob 3, and lower knob 4 is both secured to upper knob 2 with rubber knob 3, and upper knob 2 has With the through hole run through for column 12.

Circular blanking cover button 1, rubber knob 3 and lower knob 4 are contained in upper knob 2, to form circular closure dress Put, the hasp of the hasp and lower knob 4 of upper knob 2 is overlapped, and realizes the connection of upper knob 2 and lower knob 4 in place；Upper knob 2 edge has breach, and the edge of rubber knob 3 has lug boss, and the lug boss of the breach and rubber knob 3 of upper knob 2 is matched somebody with somebody Closing, realize that upper knob 2 is installed in place with rubber knob 3, circular blanking cover button 1 is reliable relative to the axial location of rubber knob 3, So that it is guaranteed that the overall structure of circular plugging device is stable.

The bottom surface of gas dome 11 has position limiting structure, when the column 12 of gas dome 11 runs through the through hole of upper knob 2, dome The position limiting structure of lid 11 is in contact with upper knob 2, to keep gas dome 11 uniform relative to the spacing of upper knob 2.

Circular blanking cover button 1, upper knob 2, rubber knob 3 and lower knob 4 in the utility model be respectively provided with it is rounded, So that the symmetrical configuration of circular plugging device, it is ensured that overall structure consolidates；Upper knob 2 can also be respectively upper plate with lower knob 4 Chromium knob and lower chromium plating knob, to improve service life.

Circular plugging device provided by the utility model is described in detail above.It is used herein specifically individual Example is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help and understands this reality With new method and its core concept.It should be pointed out that for those skilled in the art, this is not being departed from On the premise of utility model principle, some improvement and modification can also be carried out to the utility model, these are improved and modification also falls Enter in the protection domain of the utility model claims.
