Abstract

The utility model relates to an air seperation plant technical field provides a flexible protection casing, including two ends opening's cylindric leather sheath (3), still including inside lining (2) that are located leather sheath (3), inside lining (2) but include elastic bending's spoke (22), first grommet (21) and second grommet (23). This flexible protection casing's characteristics lie in, many spoke (22) are arranged and are constituteed spoke bunch around the central line of leather sheath (3), first grommet (21) are supported in a port department of leather sheath (3) to one end fixed connection with spoke bunch, second grommet (23) are supported in another port department of leather sheath (3) to other end fixed connection with spoke bunch. When this flexible protection casing was in the contraction state, spoke (22) were supported leather sheath (3) and are outwards heaved, and sleet can not stored up in leather sheath (3) surface, consequently, the utility model discloses sleet can be reduced to the influence of leather sheath, flexible protection casing's life is improved.

Description

A kind of Telescopic protective cover

Technical field

The utility model relates to air separation unit technique field, particularly relates to a kind of Telescopic protective cover.

Background technology

Air separation plant for industrial oxygenerating provides temperature production environment for air separation, affect by temperature factor, what may occur in various degree between each integral part of air separation plant is flexible, thus Telescopic protective cover is adopted to connect adjacent two component parts, when two component parts generation relative displacement, compensated by Telescopic protective cover dilatation.

At present; Telescopic protective cover is generally made up of leather sheath; when leather sheath is in contraction schedule; leather sheath surface often can be formed " pit ", and in outdoor environment, the sleet accumulated in these " pits " can accelerate the damage of leather sheath; reduce the work-ing life of Telescopic protective cover; therefore, how to reduce the impact of sleet on leather sheath, the work-ing life of improving Telescopic protective cover becomes those skilled in the art's technical problem urgently to be resolved hurrily.

Utility model content

In view of this, the utility model provides a kind of Telescopic protective cover, and this Telescopic protective cover can reduce the impact of sleet on leather sheath, improves the work-ing life of Telescopic protective cover.

In order to achieve the above object, the utility model provides following technical scheme:

A kind of Telescopic protective cover, comprise the tubular leather sheath of open at both ends, also comprise the liner being positioned at described leather sheath, described liner comprises:

Elastically bendable spoke, around the many described spoke composition spokes bunch that described leather sheath medullary ray is arranged;

Be supported in the first grommet of a port of described leather sheath, one end of described first grommet and described spoke bunch is fixedly connected with;

Be supported in the second grommet of another port of described leather sheath, the other end of described second grommet and described spoke bunch is fixedly connected with.

Preferably, in above-mentioned Telescopic protective cover, described spoke is Steel spoke.

Preferably, in above-mentioned Telescopic protective cover, described first grommet is steel ring.

Preferably, in above-mentioned Telescopic protective cover, described second grommet is steel ring.

Preferably, in above-mentioned Telescopic protective cover, the quantity of described spoke is 5 ~ 12.

Preferably, in above-mentioned Telescopic protective cover, described leather sheath is truncated cone-shaped.

According to technique scheme, the Telescopic protective cover that the utility model provides is provided with liner in leather sheath, when Telescopic protective cover is in contraction schedule, the spoke flexural deformation of liner, and support is formed to leather sheath, leather sheath is outwards heaved, can effectively prevent leather sheath surface from forming " pit ", sleet would not be accumulated in such leather sheath surface, therefore, the utility model can reduce the impact of sleet on leather sheath, improves the work-ing life of Telescopic protective cover.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.

Fig. 1 is the layout schematic diagram of a kind of Telescopic protective cover that the utility model provides;

Fig. 2 is the schematic diagram of part 2 in Fig. 1;

Fig. 3 is the vertical view of Fig. 2.

Be labeled as in figure:

1, the first connected piece; 11, the first clip; 2, liner; 21, the first grommet; 22, spoke; 23, the second grommet; 3, leather sheath; 4, the second connected piece; 41, the second clip.

Embodiment

For the ease of understanding, below in conjunction with accompanying drawing, the utility model will be further described.

See the layout schematic diagram that Fig. 1 ~ Fig. 3, Fig. 1 are a kind of Telescopic protective covers that the utility model provides; Fig. 2 is the schematic diagram of part 2 in Fig. 1; Fig. 3 is the vertical view of Fig. 2.

A kind of Telescopic protective cover that the utility model provides, comprises the tubular leather sheath 3 of open at both ends, also comprises the liner 2 being positioned at leather sheath 3, and liner 2 comprises elastically bendable spoke 22, first grommet 21 and the second grommet 23.

Wherein, many spokes 22 are arranged around the medullary ray of leather sheath 3 and form spoke bunch;

First grommet 21 is supported in a port of leather sheath 3, and is fixedly connected with one end of spoke bunch;

Second grommet 23 is supported in another port of leather sheath 3, and is fixedly connected with the other end of spoke bunch.

See Fig. 1, Telescopic protective cover comprises leather sheath 3 and liner 2, liner 2 is between the first connected piece 1 and the second connected piece 4, leather sheath 3 wraps up liner 2, one end of leather sheath 3 is fixed on the first connected piece 1 by the first clip 11, and the other end of leather sheath 3 is fixed on the second connected piece 4 by the second clip 41.When Telescopic protective cover shrinks, leather sheath 3 is outwards propped up by liner 2, and leather sheath 3 cokled surface, avoids the formation of " pit ".

The Telescopic protective cover that the utility model provides is provided with liner 2 in leather sheath 3, when Telescopic protective cover is in contraction schedule, spoke 22 flexural deformation of liner 2, and support is formed to leather sheath 3, leather sheath 3 is outwards heaved, can effectively prevent leather sheath 3 surface from forming " pit ", sleet would not be accumulated in such leather sheath 3 surface, therefore, the utility model can reduce the impact of sleet on leather sheath, improves the work-ing life of Telescopic protective cover.
