Detailed Description

As shown in fig. 1-4, an anti-tilt structure for an expansion box of a caravan comprises a carriage 1 fixed on a chassis 2 of the caravan, wherein an opening is formed in one side of the carriage 1, the expansion box 10 penetrates through the opening, and the expansion box 10 is in sliding fit with the chassis 2 of the caravan.

A stop block 11 is fixed on the upper side of the port of the expansion box 10 in the carriage 1, and the side wall of the carriage 1 with the opening allows the stop block 11 to be stopped. A telescopic cylinder 4 is fixed on the vehicle body chassis 2, and a connector 5 is fixed on a telescopic rod of the telescopic cylinder 4. A fixing plate 9 is fixed at the lower end of the expansion box 10 part outside the carriage 1, and the lug seat 8 is fixed on the fixing plate 9. The connector 5 is movably connected with the ear seat 8 through a connecting piece.

The connecting piece is towards the one end downward sloping of ear seat 8, and the connecting piece includes connection piece 6 of two front and back symmetries, and 6 one end of connection piece is rotated with ear seat 8 and is connected, and the 6 other end of connection piece rotates with connector 5 to be connected, and the upper end and the lower extreme of two connection pieces 6 all pass through baffle 7 fixed connection, and the baffle 7 and the 8 upper end contact of ear seat of top then block the connecting piece rotation.

In the process that the expansion box 10 extends out, when one end of the expansion box 10 outside the carriage 1 inclines downwards, the connecting piece is allowed to rotate on the connecting head 5, so that the expansion box 10 can be prevented from applying downward pressure to the expansion rod of the expansion cylinder 4, and the service life of the expansion cylinder 4 can be prolonged. After expansion box 10 stretches out, after dog 11 and carriage 1's lateral wall contact, the telescopic link of telescoping cylinder 4 continues to promote expansion box 10 lower extreme, because expansion box 10 upper end is blockked, when expansion box 10 lower extreme received thrust, expansion box 10 one end in the carriage 1 outside can upwards be raised, thereby can prevent the 10 one end downward sloping in expansion box in the carriage 1 outside, conveniently install strutting arrangement and support it in expansion box 10 lower extreme, can prevent that rack 3 from taking place the bending after being extruded for a long time.

As shown in fig. 5, a plurality of racks 3 are fixed at the lower end of the expansion box 10, the length direction of the racks 3 is parallel to the movement direction of the expansion box 10, the racks 3 are slidably clamped in sliding grooves on the vehicle body chassis 2, gears 12 are rotatably connected in the sliding grooves, the gears 12 are engaged with the racks 3, the plurality of gears 12 are fixedly connected through connecting rods 13, and the connecting rods 13 are rotatably connected with the vehicle body chassis 2. Through the cooperation of setting up rack 3 and gear 12, when expansion box 10 is pushed to the carriage 1 outside by the telescopic link of telescoping cylinder 4, can make expansion box 10 whole to carriage 1 outside direction synchronous motion, prevent that expansion box 10 from taking place the slope at the horizontal direction to the in-process of carriage 1 outside motion.

When the expansion box 10 needs to be pushed to the outer side of the carriage 1, the telescopic cylinder 4 is started, the telescopic rod of the telescopic cylinder 4 moves towards the direction of the outer side of the carriage 1, when the telescopic rod of the telescopic cylinder 4 applies thrust to the lower end of the expansion box 10 through the connecting piece, the lug seat 8 and the fixing plate 9, the connecting piece cannot rotate due to the fact that the baffle 7 above the telescopic cylinder contacts with the upper end of the lug seat 8, and therefore the telescopic rod of the telescopic cylinder 4 can push the expansion box 10 to move towards the direction of the outer side of the carriage 1. Along with the continuous motion of expansion box 10 to the outside direction in carriage 1, the expansion box 10 one end in the carriage 1 outside can the downward sloping, and when the expansion box 10 one end in the carriage 1 outside downward sloping, the connecting piece can rotate on connector 5, consequently can avoid expansion box 10 to exert decurrent pressure to the telescopic link of telescoping cylinder 4, can improve the life of telescoping cylinder 4. After the stop block 11 at the upper end of the expansion box 10 is stopped by the side wall of the carriage 1 with the opening, the thrust is continuously applied to the lower end of the expansion box 10 by the telescopic rod of the telescopic cylinder 4, and one end of the expansion box 10 at the outer side of the carriage 1 can be lifted upwards, so that one end of the expansion box 10 at the outer side of the carriage 1 can be prevented from inclining downwards, the supporting device is conveniently installed at the lower end of the expansion box 10 to support the expansion box, and the rack 3 can be prevented from being extruded for a long time to be bent.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
