Background

Domestic current railway passenger train curtain box structure adopts the wooden beam to pass through the fix with screw on the side wall board more, the cover is decorated to upper portion direct mount angle type, structural reliability is poor, fire behavior is low, simultaneously the angle type decorates the outer bright nail of leaking of cover sideboard and wooden beam junction and is unsightly, and decorate cover and slide for the installation angle type, need very thick very wide wooden beam bearing, need bore the counter bore earlier and twist the screw when leading to fixed this roof beam, it is more troublesome to install, unsatisfied Thailand railway passenger train's designing requirement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a satisfy the novel aluminium alloy curtain box mounting structure who has fire behavior of Thailand railway carriage design requirement, safe and reliable, it is more pleasing to the eye to have the apparent nail of outer hourglass, and the installation is simple.

In order to realize the utility model, the utility model provides a novel curtain box structure of aluminium alloy no outer blind nail, its characterized in that: the outer decorative section covers the outer side of the slide way section and is connected with the inner side of the slide way section through screws, and the exposed nails do not leak outwards and are firm and reliable.

Furthermore, the slideway section is of a T-shaped structure, a T-shaped upper cross beam is fixedly connected with the side wall plate, a sliding groove is arranged below a T-shaped lower vertical beam, and a sliding block is arranged in the sliding groove.

Furthermore, the external decorative section bar is of a L-shaped structure, an L-shaped reinforcing rib is arranged inside the L-shaped decorative section bar to form a reinforced cavity structure with the external decorative section bar, and the L-shaped reinforcing rib is connected with a vertical beam of the T-shaped slideway section bar.

Furthermore, an inward concave step is designed on one side, close to the side wall, of the upper portion of the T-shaped slideway section bar cross beam, an embedded groove is formed between the inward concave step and the side wall, the left side of the L-shaped external decorative section bar is bent downwards, and the bent end is connected with the embedded groove in an inserting mode, so that the uneven defect of the side wall is overcome.

Furthermore, the facade of the concave step inclines inwards from top to bottom to form a trapezoid groove with a large upper part and a small lower part with the side wall, and meanwhile, the inner side surface of the left bending end of the L-shaped external decorative section is processed into an inclined plane matched with the facade of the concave step, so that the L-shaped external decorative section and the concave step can be conveniently and smoothly spliced.

Further, the spout tip is equipped with the sprue, prevents that the slider from deviating from.

The utility model discloses changed the structure that the cover was decorated to traditional internal current railway carriage timber beams upper portion direct mount angle type, developed a novel aluminium alloy does not have the curtain box structure of outer bright nail of leaking, cover outside the slide section bar through outside decoration section bar and pass through bolted connection in inside with the slide section bar to and be equipped with enhancement chamber structure in the outside decoration section bar, think about ingeniously, realize that the bright nail does not have outer leaking, moreover sturdy and reliable structure, the installation is simple, and satisfied the requirement that the railway carriage of Thailand beautifully does not have the timber structure.

Detailed Description

Referring to fig. 1 and 2, the blind window curtain box structure without external leakage comprises a slideway section bar 1, an external decorative section bar 2, a sliding block 3, a rivet nut 4, a fastening screw 5 and a block 6. The slide section bar 1 is T font structure, T font entablature and side wall board fixed connection, and outside decorative section bar 2 covers and is connected through screw 5 and rivet nut 4 with the slide section bar inside outside the slide section bar 1, and side wall end outside decorative section bar 2 is embedded grafting with T font slide section bar 1, remedies the uneven defect of side wall. Be equipped with slider 3 in the spout of T font lower limb vertical beam, the spout tip is equipped with sprue 6, prevents that the slider from deviating from. The exposed nail has no leakage and is firm and reliable.

Referring to fig. 3, a T-shaped upper cross beam 103 is fixedly connected with the side wall board, a sliding groove 104 is arranged below a T-shaped lower vertical beam 105, a round hole 102 is respectively arranged on the upper part and the lower part of the cross beam, and a long round hole 106 is arranged on the vertical beam. An inner concave step is designed at one side of the upper part of the beam close to the side wall, the vertical surface 101 of the inner concave step inclines inwards (the side wall side) from top to bottom to form an embedded trapezoid groove with a large upper part and a small lower part with the side wall,

referring to fig. 4, the external decorative section is of a "l" shaped structure, the left side of the external decorative section is bent downwards, and the inner side surface 206 of the bent end 201 is processed into an inclined surface matched with the vertical surface 101 of the concave step, so that the external decorative section and the vertical surface 101 of the concave step can be conveniently and smoothly spliced. L-shaped reinforcing ribs 203 and an external L-shaped edge are arranged inside the L-shaped external decorative section to form a reinforced cavity structure 204, and rivet nut mounting holes 205 are formed in the joints of the L-shaped reinforcing ribs 203 and the vertical beams of the T-shaped slideway section.

During installation, firstly the slide section bar 1 is fixed on the side wall plate through the fastening screw 5, then the external decoration section bar 2 is spliced with the slide section bar 1, after the clearance is adjusted, the external decoration section bar is fastened with the rivet nut 4 through the fastening screw 5, and after the sliding block 3 is scratched into the sliding groove from the end part of the sliding groove, the sliding block 3 is prevented from being separated from the sliding groove by the blocking block 6 fixed at the end part of the sliding groove.

The utility model discloses changed the domestic current passenger train that has the bright nail of railway carriage of tradition and leaked outward's curtain box mounting structure, realized not having the bright nail of leaking outward, sound construction is reliable, and the outward appearance is more pleasing to the eye, has satisfied the requirement that no wooden structure of Thailand passenger train was prevented fires moreover.
