Description

Run through a bellows elbow device

The technical field is as follows:

the utility model belongs to the technical field of rail transit equipment, concretely relates to link up a bellows elbow device can make the bellows become the multiple ring structure by an ring.

Background art:

the through passage is an internal passage for passengers to freely walk from one carriage to another carriage of the rail transit vehicle and enable the passengers to feel safe and comfortable, the folding shed is one of important components of the through passage, and the folding shed is used at the joint between two vehicles or carriages and plays the roles of isolating external noise and heat transfer and sealing. The folding shed is made of multi-fold annular shed cloth fabric through sewing, each annular shed cloth consists of an elbow, transverse cloth and vertical cloth, the structure of the folding shed can influence the stretching amount of the through passage, and the elbow of the folding shed is a key component of the whole folding shed structure.

Most of the elbows formed by the folding sheds in the current market are U-shaped structures sewn by three pieces of cloth, for example: the folding shed cloth structure of the windshield of the railway vehicle disclosed in the Chinese patent 201621292092.6 comprises straight cloth, elbow shed cloth and elbow straight cloth; the straight cloth and the elbow straight cloth are both strip-shaped, and the elbow shed cloth is arc-shaped; the two ends of the straight cloth are respectively provided with elbow straight cloth and a plurality of elbow shed cloth; the elbow straight cloth is arranged between the adjacent elbow shed cloth; straight cloth and elbow canopy cloth formula as an organic whole, the radian of elbow canopy cloth is to straight cloth both sides bending, and the elbow is directly distributed and is passed through the sewing thread with straight cloth and adjacent elbow canopy cloth respectively and be connected, the elbow canopy cloth all is the symmetric distribution in the both ends and the both sides of straight cloth, the elbow canopy cloth is 4, and every end of straight cloth sets up 2. The stretching amount is small, and particularly under the condition of limited space, the requirement of large stretching amount cannot be met. Therefore, a through-passage folding shed elbow device is developed, and in the running process of a train, the stretching and compressing amount of the annular folding shed is adjusted along with the change of a train line so as to meet the requirement of vehicle movement.

The invention content is as follows:

the utility model discloses an invention aims at overcoming the shortcoming that prior art exists, designs a through passage bellows elbow device, through the tensile volume that improves the bellows, improves the cross curve ability of through passage.

In order to achieve the purpose, the main body structure of the through passage folding shed elbow device comprises a first edge cloth, a second edge cloth, a third edge cloth, a fourth edge cloth, a fifth edge cloth, a sixth edge cloth and a connecting cloth; one end of the first edge cloth is connected with one end of the third edge cloth, and the other end of the third edge cloth is connected with one end of the fourth edge cloth; one end of the second edge cloth is connected with one end of the fifth edge cloth, and the other end of the fifth edge cloth is connected with one end of the sixth edge cloth; the other ends of the first edge cloth and the second edge cloth are respectively connected with the connecting cloth.

The utility model relates to a limit cloth, No. two limit cloths, No. four limit cloths, No. six limit cloths, No. three limit cloths and No. five limit cloths are the arc structure, and it is bar structure to connect cloth.

Compared with the prior art, the utility model, the edge cloth of the elbow is converted into three rings of the transverse cloth through the single ring of the side vertical cloth by the lap joint sewing, when the vehicle passes through the normal curve, the elbow is in the folding state, the flatness and the aesthetic property of the shed cloth frame are not affected, when the vehicle passes through the small curve, the through passage is stretched and deformed, the elbow is in the stretching state, and the folding three-ring shed cloth can ensure that the shed cloth elbow has larger stretching amount; its simple structure tailors the convenience, tailors and has optimized with the overlap joint mode to the cutting of elbow department limit cloth for it can become the multiple loop configuration from a ring, has improved the tensile volume of bellows and has link up the ability of crossing the curve.

Description of the drawings:

fig. 1 is a schematic diagram of the main structure principle of the present invention.

Fig. 2 is a schematic diagram of a single ring state according to the present invention.

Fig. 3 is a schematic diagram of the three-ring state of the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the following examples and accompanying drawings.

Example 1:

the main structure of the through passage folding elbow device related to the embodiment comprises a first edge cloth 1, a second edge cloth 2, a third edge cloth 3, a fourth edge cloth 4, a fifth edge cloth 5, a sixth edge cloth 6 and a connecting cloth 7; the first edge cloth 1 and the second edge cloth 2 in the arc-shaped structure are in mirror symmetry or can be asymmetric, one end of the first edge cloth 1 is connected with one end of the third edge cloth 3 in a sewing mode, and the other end of the third edge cloth 3 is connected with one end of the fourth edge cloth 4 in a sewing mode; one end of the second border cloth 2 is connected with one end of the fifth border cloth 5 in a sewing mode, and the other end of the fifth border cloth 5 is connected with one end of the sixth border cloth 6 in a sewing mode; the other ends of the first edge cloth 1 and the second edge cloth 2 are respectively connected with the connecting cloth 7 in a sewing mode.

When the through passage folding shed elbow device related to the embodiment is used, one end of the through passage folding shed elbow device is connected with the side vertical cloth 100, and the other end of the through passage folding shed elbow device is connected with the transverse cloth 200 to form a shed cloth frame; when the vehicle passes through a normal curve, the first border cloth 1, the third border cloth 3, the fourth border cloth 4, the second border cloth 2, the fifth border cloth 5 and the sixth border cloth 6 are all in folded states, and the flatness and the attractiveness of the shed cloth frame are not affected; when a vehicle passes through a small curve, the through passage is stretched and deformed, the first edge cloth 1, the third edge cloth 3, the fourth edge cloth 4, the second edge cloth 2, the fifth edge cloth 5 and the sixth edge cloth 6 are all in a stretching state, so that a three-ring structure is formed at the bend of the shed cloth frame, a large stretching amount is guaranteed at the bend of the shed cloth frame, and the curve passing capacity of the through passage is improved.

The through passage folding shed elbow device related to the embodiment can enable the shed cloth frame elbow to form a multi-ring structure by increasing the way of folding more edge cloth, so as to provide larger stretching amount.
