The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following instance is used for illustrating the utility model, but is not used for limiting scope of the present utility model.
The utility model is in description process, easy in order to describe, and the side towards outer skeleton is called for short to " inner side ", and a side of outer skeleton is dorsad called to " outside ".
Embodiment 1:
As shown in Figures 1 to 3, suspension lining 5 of the present utility model, comprises outer skeleton 1, and outer skeleton 1 is made up of nylon 66 material, is cylindric.One end of outer skeleton 1 is provided with the radially boss 2 of projection; The other end is provided with the radially retaining barb 3 of projection.One end that outer skeleton 1 is provided with retaining barb 3 is provided with groove 11, and groove 11 extends axially along outer skeleton 1, and groove 11 extends to 1/4～1/3 position of the length of outer skeleton vertically from the end of outer skeleton 1.Retaining barb 3 comprises shank 31 and coupler body 32, and one end of shank 31 is arranged in groove 11, extend, and shank 31 has gap with groove 11 bottoms along groove 11.Coupler body 32 is connected with the other end of shank 31, and coupler body 32 stretches out the end of outer skeleton 1, and along the radial projection of outer skeleton 1.Coupler body 32 is wedge structure, and the wedge shape end face of coupler body 32 is connected with shank 31, and lozenges is along the radial projection of outer skeleton 1.The wedge shape end face of coupler body 32 is relative with boss, and the length between wedge shape end face and the inner side of boss 2 is identical with the length of lining mount pad 4.
In use, as shown in Figure 1, lining 5 enters lining installation 4 from being provided with a side pressure of retaining barb 3.While being pressed into, the one end that firmly the outer skeleton 1 of lining 5 is provided with to retaining barb 3 promotes to lining mount pad 4 vertically, first the end face of lining mount pad 4 contacts with the lozenges of coupler body 32, axial force part under the effect of lozenges along lining 5 changes into inside pressure, by inside retaining barb 3 pressing, owing to having gap between shank 31 and groove 11 bottoms, there is deformation in shank 31, move to groove 11 bottoms, coupler body 32 inwardly shrinks, and lining 5 is inserted in lining mount pad 4 smoothly.After being pressed into, as shown in Figure 3, the coupler body 32 of retaining barb 3 resets, and now, lining mount pad 4 is between the wedge shape end face of the coupler body 32 of retaining barb 3 and the medial surface of boss 2, and lining mount pad 4 cannot move axially along the outer skeleton 1 of lining 5.Adopt the anti-pressure-off structure of retaining barb and boss, simple in structure, easy to use, than the mode of prior art employing interference fit, there is stronger anti-pressure-off ability.In the time manufacturing and designing, dimension precision requirement is lower, reduces production costs.The coupler body of retaining barb adopts wedge structure, is conducive to improve the intensity of coupler body, prevents that coupler body from rupturing and separating with shank.Groove is arranged in groove, lengthens the length of shank, in the time of pressing retaining barb, avoid retaining barb fracture.Need more when rebush, firmly to the inner side pressing barb of lining, retaining barb to be shunk, lining is exited to lining mount pad, be inserted in and exit simple, easy to use.Dimension precision requirement for the outer skeleton of lining is lower, and the highly versatile of product, is convenient for changing.
Preferably, retaining barb 3 is two, and two retaining barbs 3 are symmetrical along the axle center of outer skeleton 1.Two retaining barbs 3 can better limit lining mount pad along the moving axially of lining, and prevent from use occurring rocking unstable phenomenon.Retaining barb 3 also can be selected more than three or three, and being circumferentially uniformly distributed along outer skeleton 1.
Preferably, boss 2 comprises that 21, two crescent shape projections 21 of two crescent shape projections are symmetrical along the axle center of outer skeleton 1.Boss 2 selects two crescent shape projections 21 to form, and reduces manufactured materials consumption, and projection is arranged symmetrically with, and facilitates Design and manufacture.The outside of crescent shape projection 21 is provided with strengthening rib 22, strengthens the intensity of crescent shape projection 21, prevents crescent shape projection 21 fracture failures.
Embodiment 2:
The present embodiment is substantially the same manner as Example 1, and institute's difference is: retaining barb also can adopt down " L " structure.In the time that lining is pressed into lining mount pad, need to exert oneself radially by inside retaining barb pressing on one side, coupler body is shunk, firmly lining is pressed in lining mount pad vertically on one side, comparatively trouble is installed.
Embodiment 3:
The present embodiment is substantially the same manner as Example 1, and institute's difference is: boss be one around outer skeleton circumferential hoop shape projection, and be provided with strengthening rib in the outside of ring-type projection.
Embodiment 4:
The present embodiment is substantially the same manner as Example 1, and institute's difference is: the retaining barb of the present embodiment is not established shank structure, and retaining barb is a wedge, and the end face of wedge is connected with the end of outer skeleton, and along the radial projection of outer skeleton.
Embodiment 5:
The present embodiment is substantially the same manner as Example 1, and institute's difference is: boss comprises three above projections, three above projection being circumferentially evenly arranged along outer skeleton.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
