Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is made up of fixed base 1 etc., and described fixed base 1 is provided with braking device, and described braking device comprises base 21 and centering block 22, described fixed base 1 is provided with limiting stopper 11, and described limiting stopper 11 abuts fixing with the corresponding position of base 21; The upper-end surface of described base 21 is arranged with two fixed blocks 23, same one end of two described fixed blocks 23 is equipped with up-narrow and down-wide intermediate incline, two described fixed blocks 23 are arranged with two through holes, and the upper-end surface of each described fixed block 23 is equipped with an integrated projection 24 of casting.
Described centering block 22 comprises the first inclined-plane 31 and the second inclined-plane 32, arc section 33 is provided with between two inclined-planes, on this centering block 22, one end of arc section 33 is provided with attachment hole, described centering block 22 is fixed between two fixed blocks 23 by latch 26, centering block 22 can rotate around latch 26, described centering block 22 is also arranged with two integrated blocks of casting, 25, two described blocks 25 to abut fixing with the projection 24 of respective side.
Same one end on described fixed base 1 and fixed block 23 is equipped with a fixed hole, and the two ends of described limit spring 4 are connected and fixed with the fixed hole of corresponding end respectively.
Using method of the present utility model is as follows:
As shown in Fig. 1 to Fig. 4, when not moving, the lower end of fixed base 1 is fixedly connected with base 21, two fixed blocks 23 are arranged down, latch 24 is fed through the through hole on fixed block 23 and the attachment hole on centering block 22, centering block 22 is made to be rotatably connected on fixed block 23, the abutting of the limit spring 4 between fixed base 1 and base 21 and projection 24 pairs of blocks 25 is spacing, ensure that base 21 keeps level, now, the upper-end surface of base abuts with the pin (by illustrating) on guide rail (by illustrating) and brakes, and keeps guide rail in the vertical direction static.
