Embodiment
Fig. 1 to Fig. 4 has showed the utility model pedestal 10 some details together with movable buckle 20 parts such as grade, with and installment state signal.
The form of pedestal 10 and most of protector plesiomorphism all are to be fixed on the installing rack 1, and installing rack 1 all is profile morphology as shown in fig. 1 usually, and namely the bar of a horizontal expansion has for convex tendon fixing and that strengthen; And pedestal 10 is to utilize fixed part and the installing rack 1 of its bottom to interfix.Fixed part comprises lower claw 11 and movable buckle 20, wherein descend claw 11, be positioned at a side of these pedestal 10 bottoms, i.e. downside among the figure, lower claw 11 has lower position block 12, and this lower position block 12 can be on the vertical direction of installing rack 1, also namely is engaged in the edge of this installing rack 1 on the left and right directions among the figure.Movable buckle 20 is snug fit at the bottom surface of this pedestal 10, and movable buckle 20 has upper clipping claw 22; Between movable buckle 20 and this pedestal 10 bottoms, also have locking spring 30, thereby this locking spring 30 can promote movable buckle 20 mobile locking installing rack 1. down
Fig. 1 is a state, this state-visibility is the first step of mounting base 10: the upper edge edge that upper clipping claw 22 is held on installing rack 1, and make the whole movable buckle 20 of installing rack 1 compressing that it is retreated, thereby the lower claw 11 of side, pedestal 10 below in a direction indicated by the arrow tolerant installing rack 1 enters, and then obtains another state shown in Figure 2.In state shown in Figure 2, discharge the stress of locking spring 30, thereby upper clipping claw 22 and even whole movable buckle 20 compressing installing racks 1, repercussion effect from power, final upper clipping claw 22 and lower claw 11 are in the both sides of installing rack 1, and exert pressure towards this installing rack 1, thereby whole pedestal 10 is fixed in installing rack from vertical direction (Fig. 1 and Fig. 2 about) and horizontal direction (among Fig. 1 and Fig. 2 about); This step for installing.If the step of unloading then on basis shown in Figure 2, spurs pedestal 10 integral body downwards, make lower claw 22 be enough to dodge out the downside of installing rack 1, and then press the rightabout turn pedestal 10 shown in the arrow among Fig. 1, finally can take off from installing rack 1.
As seen, in conjunction with Fig. 4, this structure has adopted the movable buckle 20 of time claw 11 and locking spring 30, make the installation/unloading operation of pedestal 10 very convenient, only need hand-held pedestal 10 to get final product by the attitude that set direction changes pedestal 10, do not need additionally to operate for certain tiny parts, thus loading and unloading fast, be adapted to narrow and small installing space.In the present embodiment, the form of upper clipping claw 22 be one by outer and in the jaws of shrinking gradually, this jaws is towards the edge of installing rack 1, and its form can be on the two sides at this installing rack edge with its clamping, the upper clipping claw 22 of this form has adaptive function, the installing rack 1 that can mate the multi-thickness specification, and clamping stability is good, and intensity is higher.This time claw 11 has two, consists of bikini with movable buckle 20 with respect to this installing rack and fixes, and the force part is few, its attitude stabilization.
Shown in Fig. 3, locking spring 30 is embedded in the bottom surface of pedestal 10, in its both sides, the both sides that also are movable buckle 20 have two upper limit position blocks 13, this upper limit position block 13 is a supplementary structure, in the process of the installation shown in Fig. 1 or unloading, as seen whole pedestal 10 probably all concentrates on the movable buckle 20 with the force part of installing rack 1, if overexert, may cause extra damage to movable buckle 20, yet upper limit position block 13 can be engaged in the upper side of installing rack 1 fully behind the movable buckle 20 oppressed retractions in Fig. 1, cause all force parts to be transferred on this upper limit position block 13, owing to be fixed structure, so its intensity is high, and bilateral upper limit position block 13 can limit pedestal 10 lift-over occurs when loading and unloading, serious forgiveness is high, and intensity is also high.The requirement of this upper limit position block 13 is, its towards with this upper clipping claw 22 towards identical, and the minimum spacing between itself and the lower position block 12 is not less than the width of described installing rack, and installing rack 1 can freely be packed into.
By Fig. 1 and Fig. 2 also as can be known, on lower claw 11, the side of lower position block 12 has oblique surface 13, this oblique surface 13 can be oppressed this installing rack 1, it is mobile to make it promote these movable buckle 20 retractions, and this arranges the further fast-assembling advantage of having expanded, namely as long as installing rack 1 can have been dodged out in the end of lower position block 13, then only need to continue the whole pedestal 10 of compressing, can under the guiding of oblique surface 13, finish whole lockings.
Present embodiment has the improvement for being matched with on the installing rack 1 except above-mentioned, and it also has improvement aspect wiring, is mainly reflected on the wiring units 15, and is extremely shown in Figure 8 such as Fig. 5.
The wiring units 15 that has 4 symmetries on this pedestal 10, wiring units 15 have comprised pedestal 10 corresponding structures and have been used for conduction, fixing etc. connector that wherein connector just has lug plate 60 and movable sleeve 50.Lug plate 60 has a crosspiece 61 that participates in clamping wire; Movable sleeve 50 is square boxs of vertically placing, slide up and down to be matched with in the pedestal 10, and pivot bush unit is in the crosspiece of this lug plate 60; The top of this movable sleeve 50 has a screwed hole 51 that locks screw; Wherein this lug plate 60 is sides of being fixed in pedestal 10, is convenient to admit outer lead.The lug plate 60 of showing from Fig. 6 and Fig. 7 and the three-dimensional details of movable sleeve 50 are as can be known, after passing screw hole 51 from top to bottom with screw (indicate), the crosspiece 61 of its bottom compressing lug plate 60, even the precession movable sleeve 50 of screw rises with respect to lug plate 60, thereby crosspiece 61 pushes mutually with the gripper edge 52 of movable sleeve 50 bottoms, in order to fixing and electrical communication wire head.Crosspiece 61 ends of this lug plate 60 have the projection 63 that crosses out towards two ends, and this projection 63 is snug fit at an end face of movable sleeve 50 its square boxs, as shown in Figure 7.
In conjunction with Fig. 5, Fig. 6 and Fig. 7 as can be known, the end of lug plate 60 its crosspieces 61 in pedestal 10 inside has a vertical section 62; Be installed with barb 16 in each wiring units 15 of pedestal 10 and support 17, wherein, barb 16 limits the vertical direction of this crosspiece 61, and supporting seat 17 limits the horizontal direction of this vertical section 62---on this two direction, whole lug plate 60 is fixed effectively.The movable sleeve 50 of this form, lug plate 60 and even whole wiring units 15, wire head is fixed in the process between movable sleeve 50 and the lug plate 60, can itself not produce extra stress to pedestal 10, therefore just avoid pedestal 10 because the too tight cause of screw hole 51 inner bolts is damaged; On the other hand, this structure is easy to process the problem of creepage distance, and fail safe is improved.
The above, it only is the utility model preferred embodiment, so can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
