[embodiment]
Mainly reaching specific embodiment below by reference to the accompanying drawings is further described in detail test fixing device.
As Fig. 1～shown in Figure 3, the test fixing device 100 of this preferred implementation is mainly used in when the light fixture shock-testing the fixedly shock-testing part (hereinafter to be referred as test block) of light fixture, as lamp housing, Transparent Parts etc., to make things convenient for the impact test block to carry out the shock-testing of different angles multidigit point, find the thin spot of test block.This test fixing device 100 comprises base 110, first locating part 120, fixed leg 130, motion bar 140 and second locating part 150.Can be connected to after test block is placed on the base 112 between first locating part 120 and second locating part 150 and be fixed.
Wherein, the base 110 of present embodiment is preferably the square steel plate and makes, and as the steel plate of 400mm*400mm*20mm etc., at the light fixture of different size, can also design the bases 110 of different big ting models.
In conjunction with Fig. 4 and Fig. 5, first locating part 120 of present embodiment comprises a plurality of limited posts 122, correspondingly, offers a plurality of stopper slots 112 that are complementary with limited post 122 on the base 110.Limited post 122 can insert in the stopper slot 112 and be spacing, also can extract from stopper slot 112 and removes spacingly, and namely limited post 122 is movably arranged on the base 110.Preferably, limited post 122 comprises insertion section 222 and limiting section 224.Wherein the size of the size of insertion section 222 and stopper slot 112 is adaptive, is used for inserting stopper slot 112.The size of limiting section 224 is slightly larger than the size of insertion section 222, and after insertion section 222 was inserted in the stopper slot 112, the stability of whole limited post 122 better like this.The limited post 122 of present embodiment is cylindrical structure substantially, in other embodiments, can also for square, polygonized structure etc. and, limited post 122 can also be the uniform structure of size, the branch that does not namely have insertion section 222 and limiting section 224, correspondingly, need only the length of limited post 122 greater than the degree of depth of stopper slot 112.In addition, what cooperate with limited post 122 also is not limited to stopper slot 112, can also be spacing hole (not shown) of break-through base etc.
As shown in Figure 4, the stopper slot 112 on the present embodiment base 110 is row's shape and distributes, as distributing for 3*3 arranges shape.And the spacing between the adjacent stopper slot 112 of every row is with reducing gradually near described fixed leg 130.When fixing test spare, at the test block of difformity size, the stopper slot 112 that can choose suitable row cooperates limited post 122, with second locating part, 150 fixing test spares.
As shown in Figure 6 and Figure 7, the fixed leg 130 of present embodiment has two burnishing surfaces that be arranged in parallel 132.Burnishing surface 132 extends axially along fixed leg 130.Offer the adjustment hole 134 that laterally runs through fixed leg 130 on the fixed leg 130.Preferably, the adjustment hole 134 of present embodiment is opened on two burnishing surfaces 132, and two burnishing surfaces 132 of UNICOM.Adjustment hole 134 roughly is the square pore structure among Fig. 6 and Fig. 7, and it axially has certain length fixed leg 130.In other embodiments, adjustment hole 134 can also be for being opened in two wedge type holes 136 on the burnishing surface 132, and as Fig. 8 and shown in Figure 9, the bigger openend in this wedge type hole 136 axially has certain length equally fixed leg 130.
The motion bar 140 of present embodiment is threaded rod.Motion bar 140 passes adjustment hole 134 and since adjustment hole 134 fixed leg 130 axially have certain length, motion bar 140 can be in adjustment hole 134 along the axial wobble of fixed leg 130.Correspondingly, test fixing device 100 also comprises two covers and motion bar 140 nut engaged 160.Two cover nuts 160 are located at the two ends of adjustment hole 134 respectively, behind the position that regulates motion bar 140, and can be by rotation nut 160 that motion bar 140 is spacing in adjustment hole 134.In other embodiments, the quantity of nut 160 also is not limited to two covers, 3 covers or the above nut 160 of 3 covers can be arranged, to increase the power that tightens up to motion bar 140.
In other embodiments, motion bar 140 is not limited to realize by adjustment hole 134 and nut 160 with the flexible connection relation of fixed leg 130, for example can motion bar 140 and fixed leg 130 be linked together by articulated manner etc., as long as motion bar 140 can be along the axial wobble of fixed leg 130, after swinging to suitable angle position, by other snap fits that motion bar 140 is spacing in adjustment hole 134 again.
Second locating part 150 is for placing the square plate structure on the base 110.One side of second locating part 150 is connected with an end of motion bar 140, can also can be flexible connection such as hinged grade for fixedly connected.Fixedly connected for screw thread between second locating part 150 of present embodiment and the motion bar 140, namely a side of second locating part 150 offers the thread pore structure (not shown) that cooperates with motion bar 140.When second locating part 150 with after motion bar 140 is connected, by regulate motion bar 140 in adjustment hole 143 along the axial pendulum angle of fixed leg 130, just can regulate the angle between the second locating part plane, 150 place and the plane, base 110 place, thereby can be used for the fixedly test block of difformity structure.For example, as shown in figure 10, when the end that is connected with second locating part 150 of axially regulating motion bar 140 downwards along fixed leg 130, again to the other end of adjusted motion bar 140, and two ends are fixed on two burnishing surfaces 132 by nut 160, can form the angle position of second locating part 150 with base 110 shown in Figure 8.
In addition, can also laterally advance or retreat the distance that motion bar 140 is regulated between second locating part 150 and first locating part 120, corresponding adjustment process can get final product by regulating two positions of hold-down nut 160 on motion bar 140.
When being connected by articulated manner between motion bar 140 and second locating part 150, the angular adjustment between second locating part 150 and the base plate 110 is more convenient, as can just can directly not regulating above-mentioned angle by swing motion bar 140.
This test fixing device 100 in use, test block can be placed in the middle of the device, regulate first locating part 120 and motion bar 140, light fixture can be connected to base 110, between first locating part 120 and second locating part 150, profiled test spare at the difformity light fixture, can regulate angle between second locating part 150 and the base 110 by regulating motion bar 140, and then carry out shock-testing, easy to adjust, test process is simple, can carry out the shock-testing of each angle different loci to profiled test spare, conveniently finds the thin spot of test block, and fixed, the reliability height.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
