Abstract

The utility model discloses a four-board linkage expanding square cabin, whose structure is that two side faces of a fixed cabin are connected with expanding cabins, and each expanding cabin is hinged with an expanding roof, an expanding floor, an expanding side plate, and an expanding front end plate, and an expanding back end plate; the expanding side plate comprises an upper side plate and a lower side plate hinged together by hinges, and the upper edge and the lower edge of the expanding side plate are respectively hinged with the out edges of the expanding roof and the expanding floor. The expanding side plate of the utility model comprises an upper side plate and a lower side plate with parallel upper edges and lower edges hinged together by hinges, so when the expanding cabin expands, the expanding roof does not need pushing very high to realize four-board linkage expanding, and the front end plate and the back end plate can be conveniently pushed to pivot at the hinge shaft rotating and expanding. The utility model has the advantages of expanding stability and safety, simple structure, and easy maintenance. When the expanding cabin is expanded by a power driving, the hydraulic system can drives the expanding roof and the expanding floor expanding to drive the expanding side plate, and the hydraulic drive is easy for adjusting and controlling, so the expanding cabin can expand stably.

Description

Four plates interlock expanded shelter

Technical field

The utility model relates to a kind of expanded shelter, the expansion side plate of expansion tank and external drive device in particularly a kind of expanded shelter.

Background technology

Shelter or closed lorry body need to enlarge usable floor area or volume sometimes, for usable floor area or the volume that enlarges shelter or closed lorry body, can be connected with expansion tank in the side of shelter or closed lorry body.In the prior art, Chinese patent 98 8 06889.3 discloses a kind of three plates interlock expanded shelter, this expanded shelter has lineal hexahedral shape sealed cabin, the side of sealed cabin is connected with expansion tank, expansion tank is surrounded by telescopic roof plate, telescopic backboard, expansion side plate, expansion front end-plate and expansion end plate, the telescopic roof plate of expansion tank, telescopic backboard, expansion front end-plate and the inner edge of expansion end plate link to each other with hinge with top, bottom, front and the back of sealed cabin side respectively, and two limits of expansion side plate link to each other with hinge respectively with the outside of telescopic roof plate and telescopic backboard.This three plates interlock expanded shelter has following deficiency:

1. telescopic roof plate, telescopic backboard and the expansion side plate of the interlock of three plates are in the exhibition time receiving, the outside of telescopic roof plate will drive expansion side plate and telescopic backboard and be lifted to and make expansion side plate and telescopic backboard at grade, be equivalent to expand the height of side plate and telescopic backboard width sum, telescopic roof plate, expansion side plate and telescopic backboard descend by gravity then, can produce impact shock during decline, make expansion tank bad in exhibition time receiving shakiness, safety;

2. for telescopic roof plate, telescopic backboard and expansion side plate exhibition time receiving with the power drive expansion tank, hydraulic cylinder and electric winch two parts drive unit need be arranged, hydraulic cylinder is hinged between sealed cabin and the telescopic roof plate, between electric winch sealed cabin and telescopic backboard, two cover drive units make expansion tank complex structure, many, the maintenance trouble in trouble point, and two kinds of drivings are not easy to control expansion tank and steadily open up receipts.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose steady, safety of a kind of exhibition time receiving, and is simple in structure, easy to maintenance, controls the four plates interlock expanded shelter that expansion tank is steadily opened up receipts easily.

The utility model is realized with the following method.

Four plates interlock expanded shelter has the hexahedron sealed cabin, two sides of sealed cabin are connected with expansion tank, expansion tank has telescopic roof plate, telescopic backboard, the expansion side plate, expansion front end-plate and expansion end plate, telescopic roof plate, telescopic backboard, the expansion side plate, expansion front end-plate and expansion end plate have inner edge parallel to each other and outside, telescopic roof plate, telescopic backboard, the inner edge of expansion front end-plate and expansion end plate respectively with the top of sealed cabin side, following, the front links to each other with hinge with the back, the expansion side plate is connected to form with hinge by epipleural and lower side panel two boards, the axis of hinge is parallel with the bottom and upper segment of expansion side plate between epipleural and lower side panel, and the bottom and upper segment of expansion side plate links to each other with hinge with the outside of telescopic roof plate and telescopic backboard respectively.

Telescopic roof plate of the present utility model, telescopic backboard link to each other with hinge successively with four blocks of plates of epipleural and lower side panel of expansion side plate, because the expansion side plate is connected to form with hinge by epipleural that parallels with upper and lower limit and lower side panel two boards, the expansion tank exhibition time receiving, do not need can realize four plates interlock exhibition receipts to the very higher position that telescopic roof plate promotes, front end-plate and end plate can promote to open up receipts around its hinge axis easily.Steady, safety of the utility model exhibition time receiving, simple in structure, easy to maintenance.When opening up the time receiving with the power drive expansion tank, available hydraulic drives telescopic roof plate and telescopic backboard telescopic motion, drives expansion side plate exhibition receipts, and hydraulic-driven is easy to regulate and control, makes expansion tank steadily open up receipts.

Below in conjunction with accompanying drawing, the utility model is further described.

The specific embodiment

Fig. 1, among Fig. 2, four plates interlock expanded shelter has hexahedron sealed cabin 1, two sides of sealed cabin are connected with

expansion tank

2,3, expansion tank has telescopic roof plate 4, telescopic backboard 5, expansion side plate 6, expansion front end-plate 7 and expansion end plate 8, telescopic roof plate, telescopic backboard, the expansion side plate, expansion front end-plate and expansion end plate have inner edge parallel to each other and outside, telescopic roof plate, the inner edge of telescopic backboard and expansion front end-plate and expansion end plate respectively with the top of sealed cabin side, following, the front,

back hinge

24,9,10,23 link to each other, the expansion side plate is connected to form with hinge 13 by epipleural 11 and lower side panel 12 two boards, the axis of hinge is parallel with the bottom and upper segment of expansion side plate between epipleural and lower side panel, the bottom and upper segment of expansion side plate respectively with the outside of telescopic roof plate and telescopic backboard with
