CN203511434U - Tightening structure for wagon hood - Google Patents

Abstract

The utility model discloses a tightening structure for a wagon hood, and belongs to a matched structure of a wagon carriage hood. The tightening structure comprises a locating block and a tensioning block, wherein the locating block is connected with the tensioning block through a fixing shaft, the fixing shaft enters the tensioning block and is provided with a tensioning spring in a sleeved mode, and a gap is kept between the locating block and the tensioning block through the tensioning spring. Through the spring on the fixing shaft, the gap is formed between the connected ends of supporting framework assemblies of the hood, and therefore flexible hood cloth fixed at the upper portion of the hood can keep tightened, and the phenomenon of water accumulation caused by surface looseness is effectively avoided. Meanwhile, the tightening structure for the wagon hood can be used as a connection structure between supporting framework assemblies of hoods of various wagons, and is wide in application range.

Description

Tightening structure for hood

Technical field

The utility model relates to a kind of supporting structure of lorry body canopy, and in particular, the utility model relates generally to a kind of tightening structure for hood.

Background technology

At present, the flexible tarpaulin surface of using on lorry body is subject to the impact of frame assembly connection structure, be prone to lax state, in the rainy day, be prone to ponding, even because ponding too much causes tarpaulin to subside, and affect the aesthetic property of railway carriage, be therefore necessary to make further improvements for the connection structure of railway carriage frame assembly.

Utility model content

One of the purpose of this utility model is for above-mentioned deficiency, and a kind of tightening structure for hood is provided, and to expect to solve flexible tarpaulin surface relaxation in prior art, is prone to the technical matterss such as ponding.

For solving above-mentioned technical matters, the utility model by the following technical solutions:

A kind of tightening structure for hood provided by the utility model, described tightening structure comprises locating piece and tension piece, described locating piece is connected with tension piece by anchor shaft, described anchor shaft enters the inside of tension piece, and on anchor shaft, be also set with tensioning spring, for being made by tensioning spring, between locating piece and tension piece, keep gap.

As preferably, further technical scheme is: described tension piece is corner structure.

Further technical scheme is: described locating piece is installed in the inside of junction, hood support frame assembly end with tension piece, and matches with the inner chamber of hood support frame assembly.

Compared with prior art, one of the beneficial effects of the utility model are: by the spring on anchor shaft, make formation gap, the interconnective end of hood support frame assembly, thereby make the fixing flexible tarpaulin in its top keep the state of tightening, effectively avoided occurring the lax seeping phenomenon causing because of its surface, a kind of tightening structure for hood provided by the utility model can be used as the connection structure between all kinds of lorry hood upper support frame assemblies simultaneously, and field of application is wide.

Accompanying drawing explanation

Fig. 1 is for the structural representation of an embodiment of the utility model is described;

In figure, 1 is that locating piece, 2 is strained pieces, 3 anchor shafts, 4 are that tensioning spring, 5 is hood support frame assembly.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further elaborated.

Shown in figure 1, an embodiment of the present utility model is a kind of tightening structure for hood, in the present embodiment, tightening structure should comprise locating piece 1 and tension piece 2, described locating piece 1 is connected with tension piece 2 by anchor shaft 3, described anchor shaft 3 enters the inside of tension piece 2, and on anchor shaft 3, is also set with tensioning spring 4, for being made by tensioning spring 4, between locating piece 1 and tension piece 2, keeps gap.

In the present embodiment, anchor shaft 3 between locating piece 1 and tension piece 2 can make to form gap between the two, tensioning spring 4 at its outside suit can be used for adjusting the size in gap between the two, to adapt to the flexible tarpaulin of dissimilar hood, makes its state in tightening.

Just as described above, above-mentioned locating piece 1 and tension piece 2 are installed in the inside of hood support frame assembly 5 junctions, end, and match with the inner chamber of hood support frame assembly 5, so that the tightening structure in above-described embodiment can be applied on lorry body.

Shown in Fig. 1, contriver is with reference to the conventional structure of hood support frame assembly 5 on existing lorry body, think and preferably above-mentioned tightening structure is arranged to the corner junction of support frame assembly 5 and assembly, need tension piece 2 to be set to the structure of corner shape.

" embodiment " that spoken of in this manual, " another embodiment ", " embodiment ", etc., refer to specific features, structure or the feature in conjunction with this embodiment, described and be included at least one embodiment that the application's generality describes.In specification sheets, a plurality of local appearance statement of the same race is not necessarily to refer to same embodiment.Furthermore, while describing a specific features, structure or feature in conjunction with arbitrary embodiment, what advocate is in conjunction with other embodiment, to realize this feature, structure or feature also to drop in scope of the present utility model.

Although the utility model is described with reference to a plurality of explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the constituent elements of subject combination layout and/or layout.Except modification that constituent elements and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
