Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

A book reading car extension channel comprises a steel pulley supporting beam, wherein the steel pulley supporting beam comprises a left steel pulley supporting beam 1 and a right steel pulley supporting beam 2, the left steel pulley supporting beam and the right steel pulley supporting beam are welded with a front supporting beam 3 and a rear supporting beam 4, the left steel pulley supporting beam, the right steel pulley supporting beam, the front supporting beam and the rear supporting beam form a framework, the top of the framework is welded with an upper frame 5, the bottom of the framework is welded with a lower frame 6, the left steel pulley supporting beam is connected with a left directional pulley track 7, the left directional pulley track is connected with a left steel pulley 8, the right steel pulley supporting beam is connected with a right directional pulley track 9, the right directional pulley track is connected with a right steel pulley 10, the top of the framework is riveted with a t2.0 patterned aluminum plate 11, the upper frame surrounds the t2.0 pattern aluminum plate, and the front supporting beam and the rear supporting beam are connected with a group of cross supports 23.

Front support crossbeam welding plug bush 12 and U-shaped mounting 13, the plug bush close fit insert the inserted bar 15 of guardrail 14, the U-shaped mounting clip the floorbar 16 of guardrail and pass through the bolt fastening, lower frame connect can hide landing leg 17 and pass through the screw connection fixed, can hide the landing leg round the screw rotate, the skeleton connect collapsible cat ladder 18, collapsible cat ladder connect and rotate cover 19, the cover close fit of rotating connect collapsible cat ladder guardrail 20.

The lower frame is provided with the bearing grooves 21 capable of hiding the supporting legs, the foldable ladder stand is fixedly connected with the clamping plates 22, and the clamping plates are clamped with the edge of the upper frame.

Recently, the company develops a book reading vehicle according to market demands, and the book reading vehicle applies an extensible channel structure which is newly developed by the company.

Example 2

The main construction process of the book reading vehicle expansion channel in embodiment 1 is welding, and mainly steel pulley support beams on two sides are welded with an upper frame, a lower frame and a support cross beam into a whole. Then the pulleys on the two sides are arranged on the support beam, and finally the t2.0 pattern aluminum plate is connected with the framework into a whole through a riveting process.

A pulley rail is manufactured by bending a steel plate and then welded with a support beam of the pulley rail into a whole. And finally, the carriage body is connected with the carriage body bottom plate into a whole through a connecting piece.

And thirdly, implementing the supporting leg, wherein the supporting leg mainly comprises a square tube 40, 1.0 and a supporting leg with the length of L =150, and is connected with the channel main body through a bolt, the supporting leg can rotate around the bolt, and when the supporting leg moves to the supporting leg hiding groove, the supporting leg is locked.
