Specific embodiment

It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model Mode is applied to elaborate to the utility model.

As shown in Figure 1 to Figure 3, the embodiments of the present invention disclose a kind of framed bent for rail 100, specific to use In laying rail 100.The framed bent includes: framed bent ontology 10, adjustment frame 30 and screw rod 20.Framed bent ontology 10 is made of fashioned iron, The framed bent ontology 10 has the structure (identical as the structure of rail 100 is placed in the prior art) for placing rail 100, so that iron Rail 100 can be placed on it.Two sides in the width direction of framed bent ontology 10 are provided with adjustment frame 30, and screw rod 20 is located at framed bent Two sides on the width of ontology 10, and the screw rod 20 of the two sides of framed bent ontology 10 respectively corresponds and wears adjustment frame 30.It is practical at this In novel, adjustment frame 30 is made to form two installation sites in the width direction of framed bent ontology 10, in this way, working as roadbed 200(rail 100 need to be laid on roadbed 200) width it is smaller when, by making the adjustment frame 30 of two sides of framed bent ontology 10 be maintained at phase The distance between screw rod 20 of two sides for making framed bent ontology 10 in close installation site reduces, and then makes the screw rod 20 of two sides Lower end can be supported on roadbed 200, and when the width of roadbed 200 is larger, the tune of the two sides by making framed bent ontology 10 Whole frame 30 be maintained in mutually separate installation site and the screw rod 20 of the two sides that make framed bent ontology 10 the distance between increase, into It and be supported on the lower end of the screw rod 20 of two sides also can on roadbed 200.

The advantage of above-described embodiment is:

By adding adjustment frame 30, and make adjustment frame 30 that two installation sites, Jin Erneng are set relative to framed bent ontology 10 Enough change the distance between two sides screw rod 20, and then makes the screw rod 20 of two sides that can be supported at least two different in width always On roadbed 200.

One preferred embodiment of the utility model provides a kind of two sides installation site for being capable of providing adjustment frame 30 Structure, it may be assumed that framed bent ontology 10 is provided with two column through-holes 11 close to the position of two sides in the direction of the width；Adjustment frame 30 is by wearing The bolt 40 of its own and two column through-holes 11 forms two installation sites in the direction of the width.In the present embodiment, work as needs When adjusting two sides screw rod 20 to small distance, bolt 40 is made at least to wear the through-hole 11 further from the side of framed bent ontology 10 On, and when needing to make two sides screw rod 20 to adjust to relatively large distance, wear bolt 40 closer to the side of framed bent ontology 10 On through-hole 11, and then make adjustment frame 30 that there are two installation sites relative to framed bent ontology 10.Preferably, adjustment frame 30 is hanging down It is directly U-shaped in the section in width direction, the position that adjustment frame 30 is connect with framed bent ontology 10 is buckled in outside framed bent ontology 10.

In a preferred embodiment of the utility model, be provided with adjustment block 50 in adjustment frame 30, adjustment block 50 by Shaft 51 is articulated in adjustment frame 30；Wherein: being arranged with adjusting hole centered on shaft 51 on adjustment block 50 and adjustment frame 30 53, adjustment block 50 is by the pin shaft 52 of the different adjusting holes 53 worn in adjustment block 50 and adjustment frame 30 and relative to adjustment frame 30 Form different angle posture；Screw rod 20 wears adjustment block 50 and is threadedly coupled with the formation of adjustment block 50.In the present embodiment, a side Face can be realized by the screw rod 20 of 10 two sides of synchronous rotary framed bent ontology to framed bent ontology 10(or rail 100) Height adjusts；On the other hand, by making pin shaft 52 wear different adjusting holes 53, and then 50 relative level of adjustment block can be changed The angular pose in face, and rotary screw 20 is combined, and then realize the adjustment to the horizontal attitude of framed bent ontology 10.Preferably, it sells Axis 52 is β pin.

Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new In the protection scope of type.
