Embodiment

As Figure 1-3, fixture comprises fixed base 1, slide fastener 2 and stage clip 3.Fixed base 1 is made up of two baffle plates 19 (19 ') of base plate 18 and base plate 18 both sides, and the middle part of base plate 18 is provided with chute 5, and the two ends of fixed base 1 are upwards turned over respectively to turn 90 degrees and constituted two pairs of fixture blocks: fixture block 7 and fixture block 7 ', fixture block 8 and fixture block 8 '.One side of being partial to fixture block 8 at the middle part of base plate 18 slightly is provided with base grab 4 and base grab 4 on 6, two baffle plates 19 of base fulcrum of spring (19 ') ', also be provided with some mounting holes 9 on the base plate 18.Slide fastener 2 is made up of slide plate 16 and two blocks of side plates 17 (17 '), the two end part of slide plate 16 are provided with pressing plate 12 and anticreep fixture block 13 respectively, be respectively arranged with on the biside plate 17 (17 ') fastener grab 14 and fastener grab 14 ', fastener grab 14 (14 ') is complementary with base grab 4 (4 ') respectively, the middle part of slide plate 16 has fastener fulcrum of spring 15, also is provided with two pairs of corresponding breach on the side of slide plate 16: breach 10 (10 ') and breach 11 (11 ').Wherein, two pairs of breach 10 (10 ') of slide fastener 2 and breach 11 (11 ') respectively with fixed base 1 on two pairs of fixture blocks 8 (8 ') and fixture block 7 (7 ') be complementary, be breach 10 (10 ') with breach 11 (11 ') between distance and fixture block 7 (7 ') equate with distance between the fixture block 8 (8 '), when two pairs of fixture blocks of two pairs of breach difference correspondences, slide fastener 2 can be installed in the chute 5 of fixed base 1, the two ends of stage clip 3 are installed in respectively on base fulcrum of spring 6 and the fastener fulcrum of spring 15, slide fastener 2 in chute 5 when its axis slides into the appropriate location, fixture block 7 (7 ') on the fixed base 1 acts on mutually with anticreep fixture block 13, can stop that slide fastener 2 comes off in chute 5.

When needs are installed in equipment on the guide rail, at first equipment is fixed on the fixed base 1 by mounting hole 9 with screw, by pressing plate 12 compression press springs 3 of pinning slide fastener 2, base grab 6 relative on fixed base 1 and the slide fastener 2 and the grab spacing between the fastener grab 14 are magnified, guide rail is stuck in the grab of fixture, unclamp pressing plate 12 then, the tension force of stage clip 3 makes the grab of fixture hold on to guide rail, and it is more firm that equipment is installed.By the elastic force of stage clip 2, can conveniently regulate the distance between the grab, adapting to the guide rail of different size, and dismounting is all very convenient.

When stage clip 3 used extension spring to substitute, an end of extension spring was fixed on the fixed base 1, and the other end of extension spring is provided with little hook, and the hanging ring of corresponding little hook is set on the slide fastener 2.The mounting hole 9 that is provided with on fixed base 1 has multiple model, to adapt to the installation needs of distinct device, because the area of the base plate 18 of fixed base 1 is limited, so slide fastener 2 and fixed base 1 are designed to dismountable form, when equipment being fixed on the fixed base 1, its mounting hole of selecting for use is subjected to the influence of slide fastener 2, can earlier removable fastener 2 be pulled down from fixed base 1, after being fixed on equipment on the fixed base 1, again slide fastener 2 and stage clip 3 (extension spring) are installed together.In addition, also can be fixed into one with fixed base 1 be non-removable to slide fastener 2.Fixture all is to adopt metallic material to make, and its stationarity and serviceability are extremely strong, are adapted to the installation of plurality of devices, the setting of spring makes things convenient for the dismounting of equipment, has shortened workman's field installation time, improved the working efficiency of installing, and the working life that has strengthened fixture.
