Abstract

The utility model relates to an expandable cabin (box) body for moving facilities as a military square cabin, an expansion vehicle, and a mobile house. The utility model comprises a fixed box body with a fixed floor and a fixed roof, and both sides of the fixed floor and the fixed roof are respectively installed with fixed jointed shafts; while number of the fixed jointed shafts on the top and at the bottom of both sides is four, and two movable jointed shafts are installed between the between the top fixed jointed shaft and the bottom fixed jointed shaft at each side of the fixed floor and the fixed roof; three movable box plates are connected head-to-tail between the fixed jointed shaft and the movable jointed shafts at one side, and the three movable box plates can fold or expand through the jointed shafts. The utility model can considerably expand using space of the box body; simultaneously, the utility model has the advantages of simple structure, and easy installation and transportation.

Description

But expansion tank (railway carriage or compartment) body

Technical field

But the utility model relates to a kind of expansion tank (railway carriage or compartment) body that is used for MOVING STRUCTUREs such as Military Shelter, expansion car, prefabricated house.

Background technology

MOVING STRUCTURE such as Military Shelter, prefabricated house generally is as field hospital, field command post, arranges uses such as barracks or other dual-use living facilities fast.The usage space of its cabin of facility (railway carriage or compartment) bodies such as existing Military Shelter, prefabricated house is more fixing mostly, is difficult to expansion, transportation and installation inconvenience.

Summary of the invention

Technical problem to be solved in the utility model is, but provides a kind of simple in structure, installation and convenient transportation, can enlarge expansion tank (railway carriage or compartment) body of usage space.

But expansion tank of the present utility model (railway carriage or compartment) body includes one has the fixed base plate and the fixing fixedly envelope of top board, fixed base plate and fixedly the dual-side of top board be respectively arranged with the axle that is fixedly hinged, on the both sides, under be fixedly hinged the axle have four, fixed base plate and fixedly each side of top board on, following two are fixedly hinged and also are provided with two between the axle and are movably hinged axle, the axle and be movably hinged between the axle head and the tail and be connected with three blocks of movable railway carriage or compartment plates of being fixedly hinged in a side, three blocks of movable railway carriage or compartment plates can fold or expand by jointed shaft, three blocks of movable railway carriage or compartment plates are positioned at approximate vertical position when folded state, and three blocks of movable railway carriage or compartment plates constitute the end face of an extending space respectively when extended mode, side and bottom surface.

The utility model is owing to be provided with the movable railway carriage or compartment plate that is movably hinged structure in fixing envelope both sides, the usage space of expansion tank (railway carriage or compartment) body greatly after its expansion; And can have less appearance and size after its folding gathering in, thereby convenient transportation, simultaneously, its process folding and that launch is simple and efficient.

But Fig. 1 is the rounding state structural representation of the utility model expansion tank (railway carriage or compartment) body;

But Fig. 2 is the deployed condition structural representation of the utility model expansion tank (railway carriage or compartment) body;

But Fig. 3 is the expansion process schematic diagram of the utility model expansion tank (railway carriage or compartment) body.

The specific embodiment

As shown in Figure 1 and Figure 2, include one and have the fixed base plate 1 and the fixing fixedly envelope of top board 2, fixed base plate and fixedly the dual-side of top board be provided with four be fixedly hinged the axle 3, between upper and lower two jointed shafts of each side, also be provided with two and be movably hinged axle 4, three blocks of movable railway carriage or compartment plates 5 head and the tail successively are connected the axle and being movably hinged between the axle of respectively being fixedly hinged, and three blocks of movable railway carriage or compartment plates can fold or expand by jointed shaft.Three blocks of movable railway carriage or compartment plates are positioned at approximate vertical position (as Fig. 1) when folded state, and three blocks of movable railway carriage or compartment plates constitute end face, side and the bottom surface (as Fig. 2) of an extending space respectively when extended mode.

As shown in Figure 2, fixedly the height between top board and the fixed base plate is H, and the movable railway carriage or compartment plate width that is positioned at end face, side and bottom surface is respectively A, B, C, and being positioned at the movable railway carriage or compartment plate of end face and the angle of vertical direction is Φ.In actual manufacture process, not interfere mutually in order to make movable railway carriage or compartment plate draw in smoothly and to launch, each above-mentioned dimensional parameters should be followed following formula:

A＝2H/(1+SINΦ+COSΦ)；

B＝H[1-2COSΦ×(1+SINΦ+COSΦ)]；

C＝2H/(1+SINΦ+COSΦ)×SINΦ。

The expansion process of movable railway carriage or compartment plate as shown in Figure 3, the gathering process of movable railway carriage or compartment plate is opposite with expansion process.

Claims

1, but a kind of expansion tank (railway carriage or compartment) body, it includes one and has the fixed base plate (1) and the fixing fixedly envelope of top board (2), it is characterized in that: fixed base plate and fixedly the dual-side of top board be respectively arranged be fixedly hinged the axle (3), on the both sides, under be fixedly hinged the axle have four, fixed base plate and fixedly each side of top board on, following two be fixedly hinged also be provided with between the axle two be movably hinged the axle (4), the axle (3) and be movably hinged and be connected with from beginning to end three blocks of movable railway carriage or compartment plates (5) between the axle (4) successively of respectively being fixedly hinged in a side, three blocks of movable railway carriage or compartment plates can fold or expand by jointed shaft, three blocks of movable railway carriage or compartment plates are positioned at approximate vertical position when folded state, and three blocks of movable railway carriage or compartment plates constitute the end face of an extending space respectively when extended mode, side and bottom surface.
