The described elastic member 28 of Figure 1 and Figure 2 be installed in lip part 21 below.The part of the surface side periphery elasticity butt of these elastic member 28 formations and mounting hole, it consists of the spring section among the present invention.In addition, as spring section, can as the elastic member 28 of this example, separate formation with lip part 21, perhaps also elastomeric elastic member can be inlayed the lower surface that is formed in lip part 21 and form as one with lip part 21, in addition, also lip part 21 can be made and be the skirt shape towards oblique below and enlarge such shape, constitute surface side periphery elasticity butt with mounting hole as long as be positioned at parts below the lip part 21.
In addition, as shown in Figure 5, post section 30 is stretched out by central authorities below the straight line shape wall section 26 of lip part 21.In the occasion of this example, post section 30 is roughly tetragonal prism-shaped for cross section vertically, but also can be cylindric, can adopt various shapes.
With reference to Fig. 3 (A) and Fig. 5 (A), be formed with a pair of the first engaging pin 35,35 in described post section 30, these engaging pin 35,35 from described post section 30 with described the relative bi-side of nib 25,25 sides stretch out and be anchor pin shape towards lip part 21 and extend.Be formed with first of the back side peripheral snap of mounting hole in front end periphery of each the first engaging pin 35 and engage stepped part 36.In addition, be formed with the first abutting part 37 in the forward end periphery of the first engaging stepped part 36, when the back side peripheral snap of the first engaging stepped part 36 and mounting hole the time, interior all elasticity butts of described the first abutting part 37 and mounting hole.Described the first engaging stepped part 36 is along the axial specified altitude of post section 30, the i.e. height of H1 from the front end of post section 30 (with reference to Fig. 5 (A)) formation.The first engagement portion that this first engaging stepped part 36 consists of among the present invention.In addition, when the longitudinal center line with post section 30 was made as C1, each first engaging pin 35 opened formation with respect to described center line C1 laterally with opening angle θ 1.
In addition, be formed with a pair of the second engaging pin 40,40 at the front end of post section 30, these the second engaging pin 40,40 never stretch out the first engaging pin 35,35 relative bi-side to be risen to be roughly the angles of 90 degree with respect to the first engaging pin 35,35 and stretches out and be anchor pin shape towards lip part 21 and extend (with reference to Fig. 3 (B) and Fig. 5 (B)).Consequently, the first engaging pin 35, the 35 and second engaging pin 40,40 stretch out towards the direction that is the crosswise intersection from the front end of post section 30.In addition, best the second engaging pin 40,40 with respect to the first engaging pin 35,35 intersecting angle for roughly 90 spending.
On a pair of the second engaging pin 40, from the second engaging pin 40 forward end, be formed with the second engaging stepped part 41 and the 3rd engaging stepped part 43 along post section 30 axial different heights.Forward end periphery in the second engaging stepped part 41 is formed with the second abutting part 42, when the back side peripheral snap of the second engaging stepped part 41 and mounting hole the time, interior all elasticity butts of described the second abutting part 42 and mounting hole.In addition, the second engaging stepped part 41 forms at the height of the H2 from the front end of post section 30, and the 3rd engaging stepped part 43 forms (with reference to Fig. 5 (B)) at the height of the H3 from the front end of post section 30.
In addition, the height H 3 of the height H 2 of the second engaging stepped part 41, the 3rd engaging stepped part 43 is different height with respect to the height H 1 of described the first engaging stepped part 36, particularly, the 3rd engaging stepped part 43 is formed on (namely the 3rd engaging stepped part 43 is formed on lip part 21 position farthest) on the extreme lower position, the second engaging stepped part 41 is formed on the position that is higher than the 3rd engaging stepped part 43, the first engaging stepped part 36 is formed on the highest position, satisfies the relation of H3＜H2＜H1.
Like this, because each engaging stepped part forms with three different heights, therefore can be applicable to the part of three kinds of different-thickness.Particularly, the 3rd engaging stepped part 43 is corresponding to the thickness (with reference to Figure 13 (B) and Figure 14 (B)) after the first part 1 and the second part 5 is overlapping, the second engaging stepped part 41 is corresponding to the thickness (with reference to Figure 15 (B)) of the first thicker part 1 of thickness of slab, and the first engaging stepped part 36 is corresponding to the thickness (with reference to Figure 16 (A)) of the first thinner part 1 of thickness of slab.
In addition, the thickness number of applicable part be will be in the first engagement portion that the first engaging pin 35 forms the number on the short transverse with at the second number of the second engagement portion after the number addition on the short transverse that engages pin 40 formation, in this example, as mentioned above, owing to be provided with an engagement portion at the first engaging pin 35, be provided with two engagement portions at the second engaging pin 40, therefore can be fixed on the different part of three kinds of thickness, but by changing the number of each engagement portion, can suitably set applicable thickness number.
In addition, each second engaging pin 40 opens formation with respect to the longitudinal center line C1 of post section 30 laterally with opening angle θ 2, is than each the first engaging pin 35 to open more state with respect to the opening angle θ 1 of the center line C1 of described post section 30.Namely, occasion at the first engaging pin 35, owing to form the first engaging stepped part 36 in its forward end, therefore also can engage with mounting hole even each first engaging pin 35,35 opening angle θ 1 are less, but the occasion at the second engaging pin 40, because the front end side in post section 30 is provided with the 3rd engaging stepped part 43, therefore if make the opening angle identical with the first engaging pin 35, then can pass mounting hole and can't engage with mounting hole, therefore the second engaging pin 40,40 be formed the larger state that opens.
The result who sets as described above opening angle θ 1, θ 2 is, with the length from a side the 3rd engaging stepped part 43 to the opposing party's the 3rd engaging stepped part 43 during as the second engaging pin 40,40 open width W1 (with reference to Fig. 5 (B)), this open width W1 is greater than engaging pin 35,35 open width W2 (with reference to Fig. 5 (A)) engage first on stepped part 43 equal heights with the 3rd.Consequently, when inserting each engaging pin 35,40 in the mounting hole, especially under the state that just inserts, the second engaging pin 40 needs to do to the inside larger deflection.
To this, shown in Fig. 5 (A), Fig. 5 (B), consist of the second engaging pin 40 and the sectional area of the base end part 40a of the linking department of post section 30 and form the sectional area that engages the base end part 35a of pin 35 less than first.Consequently, the second engaging pin 40 forms than the first engaging pin 35 easy deflections, thus when above-mentioned insertion, even the second engaging pin 40 is done larger deflection to the inside, its spring-back force also a little less than, so can reduce to insert resistance.In addition, as the method for the spring-back force that causes of deflection that reduces the second engaging pin 40, for example can form breach at the base end part 40a of the second engaging pin 40, perhaps base end part 40a be made the shape of narrow width, not special restriction.
Below with reference to Fig. 6～Fig. 8 the lid 50 that is installed on the main body portion 20 is described.This lid 50 has discoideus cover plate 51.With reference to Fig. 7 (B) and Fig. 8 (A), in the outstanding annular wall section 52 that is provided with of the specified altitude from the periphery edge of this cover plate 51, be formed with the instrument insertion groove 53,53 that can insert the instruments such as straight screwdriver in the relative part of this annular wall section 52.In addition, week is formed with circular- arc engaging rib 54,54 with relative form in the opening portion of annular wall section 52, this engaging rib 54 engages with the described ring-type rib 22 of the lip part 21 of main body portion 20, thereby lid 50 is installed in (with reference to Figure 12 (B)) on the main body portion 20.In addition, shown in Fig. 8 (A), be formed with upside conical surface 54a and downside conical surface 54b in engaging rib 54,54 upper and lower surfaces, thereby easily lid 50 be installed on the main body portion 20, and easily cap 50 is pulled down from main body portion 20.
Shown in Fig. 7 (B), extension is provided with four lateral misalignment restrict foot 55 from the regulation position below the cover plate 51.This lateral misalignment restrict foot 55 is circular dividing is become the such sectional shape of four parts (with reference to Fig. 8 (B)), rectangular-shaped bight is towards the center C 2 of cover plate 51, open equal interval with respect to the center C 2 of cover plate 51 at circumferential sky and set, and be the shape of extending along the axial almost parallel of described post section 30.

Figure 10 represents be a pair of the second engaging pin 40,40 with the state after the to the inside deflection to greatest extent, at this moment, each lateral misalignment restrict foot 55 forms than the front end periphery of each the second engaging pin 40 more outstanding such size.In addition, though not shown, when the first engaging pin 35,35 with to the inside deflection to greatest extent the time, each the lateral misalignment restrict foot 55 also front end periphery than each the first engaging pin 35 is outstanding.
The below describes the using method of described anchor clamps 10.
At first, make each lateral misalignment restrict foot 55 and a pair of inserting hole 27,27 couplings, be pressed into lid 50 from the upper face side of lip part 21, engage with a pair of second between the pin 40,40 in the gap of formation thereby four lateral misalignment restrict foot 55 are set respectively at a pair of the first engaging pin 35,35.If continue to be pressed into lid 50, then the conical surface 22a of lip part 21 pushes the downside conical surface 54b of engaging rib 54 and makes laterally deflection of annular wall section 52, when lip part 21 is crossed the top of rib 54,52 elastic recoveries of annular wall section, thereby the lower surface peripheral snap of upside conical surface 54a and lip part 21, shown in Figure 12 (A), Figure 12 (B), lid 50 can be installed on the main body portion 20.At this moment since the cover plate 51 of available lid 50 will be in hole section 24 that lip part 21 forms, play the covering such as nib 25, therefore can improve outward appearance.
In addition, in anchor clamps 10 of the present invention, because each engaging pin 35,40 is respectively arranged with engaging stepped part 36,41,43 at different heights, so the engaging of the mounting hole of the various parts that anchor clamps 10 can be different from thickness.The below describes by part thickness.
What Figure 13 represented is the occasion that anchor clamps 10 are installed on the thickest part.Namely, what Figure 13 represented is the state that has used anchor clamps 10 on first parts 1 such as body panels for second parts 5 such as deflector are installed in, at this moment, the mounting hole 7 that at first makes the mounting hole 6 of circular hole of the second part 5 and slotted hole shape respectively with mounting hole 2,3 couplings of the circular hole of the first part 1, with the second part 5 butts, be provided in the first part 1 above.Under this state, with anchor clamps 10 from the second part 5 sides be inserted into respectively the mounting hole 6 that matches up and down, 2 and mounting hole 7,3.What Figure 13 represented is the state that anchor clamps 10 have been installed in mounting hole 6,2.When the mounting hole 6 that anchor clamps 10 is inserted the second part 5 is interior, each engages pin 35,40 and is mounted pushing and to the inside deflection in interior week of hole 6, the front end of post section 30 passes mounting hole 2, when the 3rd engaging stepped part 43 arrives the back side of mounting hole 2, a pair of the second engaging pin 40,40 elastic recoveries, thereby shown in Figure 13 (B), the back side peripheral snap of the mounting hole 2 of the 3rd engaging stepped part 43 and the first part 1.At this moment, shown in Figure 13 (A), because the first front end that engages pin 35 of the opposing party of engage with mounting hole 2 becomes the state with interior all crimping of the mounting hole 6 of the second part 5, so anchor clamps 10 can be installed in the mounting hole 2 in the situation that does not tilt or rock.In addition, the surface side periphery butt of the elastic member 28 below the lip part 21 and the mounting hole 6 of the second part 5, thus the first part 1 and the second part 5 become elastic member 28 and the second state that engages between the pin 40,40 of being clamped in.
In addition, anchor clamps 10 are being inserted described mounting hole 2, in the time of in 6, because the open width W1 of the second engaging pin 40 engages the open width W2 of pin 35 (with reference to Fig. 5 (A) greater than first, Fig. 5 (B)), therefore need to make the second engaging pin 40 do to the inside to engage the large deflection of pin 35 than first, but as mentioned above, because the second engaging pin 40 forms than the 35 easy deflections of the first engaging pin, the second engaging pin 40, the spring-back force that 40 to the inside deflections cause is configured to less than the first engaging pin 35, the spring-back force that 35 to the inside deflections cause, therefore can suppress to insert the increase of resistance, thereby keep easy insertion.
But, Figure 13 (A), Figure 13 (B) expression be when with respect to the center C 3 of mounting hole 2 aperture, left side of mounting hole 2 being made as R1 and the aperture, right side is made as R2 on the left of installment state in the mounting hole 2 of aperture R1 when being installed in the aperture greater than aperture, right side R2, anchor clamps 10 and having deviation.In anchor clamps 10 of the present invention, even there is deviation like this in the aperture image of mounting hole 2, also can utilize the first engaging pin 35 and second that is the extension of anchor pin shape to engage the angle θ 1 of pin 40, the deviation that θ 2 (with reference to Fig. 5) absorbs described aperture.In addition, as the opening angle θ 1 of the first engaging pin 35 and the second engaging pin 40, when θ 2 changes, the height H 3 of the 3rd engaging stepped part 43 can change slightly.Occasion at this example, the clamped position of the 3rd stepped part 43 that engages with small aperture R2 is slightly high when engaging than with large aperture R1, but because elastic member 28 with the surface side periphery elasticity butt of mounting hole 6 is installed below lip part 21, therefore the variation of above-mentioned clamped position can be by the flexible absorption of this elastic member 28, and anchor clamps 10 can fixedly secure in the situation of not rocking on the first part 1 and the second part 5.In addition, Figure 14 described later, Figure 15, Figure 16 represent also is to be the occasion of aperture R2 with respect to center of graph C left side for aperture R1, right side.
In addition, owing to be provided in each first engaging pin 35,35 second engage pin 40 with each, four lateral misalignment restrict foot 55 between 40 form when each engaging pin 35,40 with to the inside deflection to greatest extent the time than each engaging pin 35, the size (with reference to Figure 10) that 40 front end periphery is given prominence to more laterally, therefore under the state in anchor clamps 10 are fixed on mounting hole 2, even to anchor clamps 10 effect lateral external forces, engage pin 40 with a pair of second of mounting hole 2 back side peripheral snap, side in 40 is towards inboard deflection, the second engaging pin 40 of the opposing party will make engaging remove from leaving in interior week of mounting hole 2, therefore four lateral misalignment restrict foot also can limit the lateral misalignment of anchor clamps 10 with respect to mounting hole 2, can prevent reliably that anchor clamps 10 from deviating from from mounting hole 2.
What Figure 14 represented is first part 1 and second part 5 different from the first part 1 shown in Figure 13 and the second part 5 thickness.That is, the first part 1 shown in Figure 14 forms thicker than the first part 1 shown in Figure 13, and that the second part 5 shown in Figure 14 forms is thinner than the second part 5 shown in Figure 13.But, the occasion of the thickness after the first part 1 and 5 additions of the second part and Figure 13 is identical.At this moment, because actual part thickness is identical with above-mentioned occasion shown in Figure 13, so anchor clamps 10 are fixed in the mounting hole 2 (with reference to Figure 14 (A), Figure 14 (B)) in the same manner as above.
What Figure 15 represented is that anchor clamps 10 are installed in than the occasion on the thin part of the part of Figure 13 and Figure 14.That is, Figure 15 represents is to need not the second part 5 is installed on the first part 1 but anchor clamps 10 are directly installed on occasion in the mounting hole 2,6 of the first part 1.At this moment, when anchor clamps 10 being inserted mounting hole 2 when interior, each engages pin 35,40 and is mounted pushing and to the inside deflection in interior week of hole 2, when continuing to be pressed into anchor clamps 10 until during the surface side periphery butt of elastic member 28 and mounting hole 2, the back side that the 3rd engaging stepped part 43 is passed mounting hole 2, thereby the back side peripheral snap (with reference to Figure 15 (B)) of the second engaging stepped part 41 and mounting hole 2.In addition, under this state, shown in Figure 15 (A), because the first front end that engages pin 35 that engage with mounting hole 2 becomes the state with interior all crimping of mounting hole 2, so anchor clamps 10 can firmly be installed in the mounting hole 2 in the situation of not rocking.
What Figure 16 represented is the occasion that anchor clamps 10 are installed on the thinnest part.That is, Figure 16 is the occasion of mounting fixture 10 on the first part 1 of comparing less thick with the first part 1 of Figure 15.At this moment, when anchor clamps 10 being inserted mounting hole 2 when interior, each engages pin 35,40 and also is mounted pushing and to the inside deflection in interior week of hole 2, when being pressed into anchor clamps 10 until during the surface side periphery butt of elastic member 28 and mounting hole 2, both pass the back side of mounting hole 2 the 3rd engaging stepped part 43 and the second engaging stepped part 41, thereby shown in Figure 16 (A), the first engaging stepped part 36 of the first engaging pin 35 and the back side peripheral snap of mounting hole 2.Under this state, opposite with above-mentioned Figure 13～Figure 15, the front end of the second engaging pin 40 that does not engage with mounting hole 2 becomes the state with interior all crimping of mounting hole 2, and anchor clamps 10 can firmly be installed in (with reference to Figure 16 (B)) in the mounting hole 2 in the situation of not rocking.
As mentioned above, adopt described anchor clamps 10, owing to will be located at the first engaging stepped part 36 on the first engaging pin 35, and the second engaging stepped part 41 that is located on the second engaging pin 40 is set respectively different height for the 3rd engaging stepped part 43, the mounting hole engaging of the various parts that therefore anchor clamps 10 can be different from thickness, and, when a side engaging pin engages with mounting hole, the opposing party's who does not engage with mounting hole engaging pin becomes the state with interior all crimping of mounting hole, therefore can or not rock with respect to the mounting hole inclination, anchor clamps 10 firmly can be installed in the mounting hole.In addition, under the state in anchor clamps 10 are fixed on mounting hole 2, even to anchor clamps 10 effect lateral external forces, four lateral misalignment restrict foot also can limit the lateral misalignment of anchor clamps 10 with respect to mounting hole 2, can prevent reliably that therefore anchor clamps 10 from deviating from from mounting hole 2.In addition, even there is slightly deviation in the aperture, also can utilize respectively to engage pin 35,40 opening angle and the deviation of stretching to absorb the aperture of elastic member 28.
In addition, in the anchor clamps 10 of above-mentioned example, have the first engaging pin 35 and 40 two pairs of engagings of the second engaging pin pin, if but be provided with manyly to the engaging pin, for example, also can be from the front end of post section 30, to stretch out laterally across three pairs with the intervals of 60 degree to engage pin.
In addition, in the anchor clamps 10 of above-mentioned example, lateral misalignment restrict foot 55 is arranged on the lid 50 that separates with main body portion 20, but also lateral misalignment restrict foot 55 and main body portion 20 can be arranged to one.
