Abstract
The utility model relates to a door opening mechanism and belongs to the technical field of compartment containers. The door opening mechanism comprises a spring, a sleeve containing the spring, a spring press plate, a steel rope and two fixed pulleys. One end of the spring is pressed on the sleeve and the steel rope winds on the fixed pulleys, penetrates through the spring and is connected to the spring press plate which is pressed on the spring press plate at the other end of the spring. The other end of the steel rope is connected to a container wall plate to be opened. One fixed pulley is installed at the end portion of the sleeve and the other fixed pulley is installed in the middle portion of the sleeve. According to the door opening mechanism, the steel rope connected with the spring is cleverly used; when the container wall plate is expanded, energy generated when the wall plate is downwards overturned is converted into compression energy of the spring; when the container wall plate is folded, the compression energy of the spring is converted into energy for the wall plate to be upwards overturned, and the advantage of easily expanding and folding the container wall plate is achieved through simple holding of an operator.
Description
Technical field
The utility model belongs to van-type container technical field, relates in particular to a kind of door-opening mechanism of expanded type freight container.
Background technology
In various car exhibitions, exhibition side, in order to transport facility, is integrated into a freight container by exhibition booth, and the platform of take during expansion after this freight container expansion is carrier, top installing advertisement jacking system, and side installation Motorized blind is fluffy, illuminating lamp, shot-light are installed in top; While drawing transportation in, the annex of using during expansion, as ladder, guardrail, electric power distribution cabinet, tool box etc. all can be integrated into the box house of gathering, forms the integral body of a collection dress.
When the wallboard of container-type expansion platform being launched and draws in, waste time and energy, make the expansion platform of container-type when reality is used, very inconvenient.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of the wallboard of container-type expansion platform is opened, draws door-opening mechanism simply and easily in.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of door-opening mechanism, comprise spring, hold sleeve, spring bearer plate, steel rope and two fixed pulleys of described spring, described spring one end is pressed on sleeve, described steel rope is connected on the spring bearer plate that is pressed in the described spring other end on fixed pulley, through spring, the other end of described steel rope is connected on container wall panel to be opened, end that is arranged on described sleeve of described fixed pulley, another is arranged on the central region of described sleeve.
The utility model door-opening mechanism, utilize dexterously the steel rope of linking springs, when by container wall plate development, by the wallboard compression energy that the Conversion of Energy of upset is spring downwards, when container wall panel draws in, again the compression energy of spring is converted into the resupinate energy of wallboard, under the simple support of operating personal, reaches container wall plate development and draw the beneficial effect of easily realizing in.
As the utility model, further improve, described door-opening mechanism comprises locating dowel pin, described sleeve is provided with the through hole mating with described locating dowel pin, described through hole next-door neighbour spring bottom dead center position, after wallboard launches, spring moves to bottom dead center position, and locating dowel pin is inserted in the through hole on sleeve, restraining spring automatically resets, and improves the safety of door-opening mechanism.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the utility model door-opening mechanism.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
The utility model door-opening mechanism, is mainly the match mechanism that manual expansion container wall panel is expanded.
As shown in the figure, the utility model door-opening mechanism comprises spring 5, the sleeve 8 that holds described spring, spring bearer plate 4, steel rope 3 and two fixed pulleys 2, described spring one end is pressed on sleeve, described steel rope is on fixed pulley, through spring, be connected on the spring bearer plate that is pressed in the described spring other end, end that is arranged on described sleeve of described fixed pulley, another is arranged on the central region of described sleeve, container wall panel 1 is when opening, the gravity that wallboard upset produces by wire rope transfers to spring, as long as slightly doing to help, operating personal just can realize the expansion of wallboard, under the effect of pressing force of the spring, operating personal upwards touches wallboard, just can realize the gathering of wallboard.
As preferably, door-opening mechanism comprises locating dowel pin 6, described sleeve is provided with the through hole mating with described locating dowel pin, described through hole next-door neighbour spring bottom dead center position 7, after wallboard launches, spring moves to bottom dead center position 7, and locating dowel pin is inserted in the through hole on sleeve, restraining spring automatically resets, and improves the safety of door-opening mechanism.Unclamp being connected of steel rope and wallboard, the turnover panel on every wallboard is manually opened, now container-type expansion platform thoroughly launches, and the base plate of expansion platform, wallboard and turnover panel form a complete platform.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
