Description
Technical field:
The present invention relates to freight container and parts manufacturing technology field thereof, anchor fitting and method of application thereof after particularly a kind of collapsible container locking.
Background technology:
Freight container is meant that having certain intensity, rigidity and specification specializes in the large-scale loading container that turnover is used.Use the container transshipment goods, can transport to consignee's warehouse and unload, more change trains, ship time midway, need not goods be taken out in the case and change the outfit directly in the loading of shipper's warehouse.Freight container is distinguished by its structure, can be divided three classes: rigid container, collapsible container, monocoque container.In rigid container, also can divide sealed container, open top container, flat rack container etc.; Collapsible container refers to that the major part (sidewall, end wall and case top) of freight container can fold or decompose simply, can combine easily when reusing again; Monocoque container is to form a steel body to all parts, and its advantage is in light weight, can adapt to the torsion that is taken place and can not cause permanent deformation.In these several kinds of freight containers,, make its favor that more and more receives people, when transportation big machinery or military supplies article because of the constructional feature of collapsible container; Rigid container is because of its fixed sturcture, and large-scale machinery or article are inconvenient to pack into, and the monocoque container insufficient strength; At this moment, be preferably collapsible container, this freight container; With overhead traveling crane big machinery or military supplies article are sling be placed on the freight container grillage after, again the end wall of collapsible collection dress is holded up fixingly, (sidewall and case push up one normally to add or do not add cartonning top and sidewall; The both sides of end wall are slightly thicker than end wall, are concave shape), promptly accomplished packing into of goods.In like manner, it is also very convenient to unload, and the end wall of collapsible container is set level expansion get final product.In addition, the collapsible container biggest advantage is, after transportation finishes, can pile up together with the inwardly folding back of the end wall of collapsible container and with a plurality of collapsible containers, has saved the space.
At present, collapsible container on the market, in view of its foldable structure, must use locking or anchor fitting at folded part, for example, the locking after the holding up of end wall; Behind the inside fold-flat of end wall and the locking between grillage; After the collapsible container of a plurality of skies is piled up together, locking between casing and casing or the like.At present, the blocking device that the locking of these parts is used usually is twistlock, and the bar of twistlock is provided with the top spring, and a side of bar is provided with barb; During use, after twistlock inserted freight container and need the connecting bore of fixed position, rotate twistlock then, barb is hooked on the hole wall of connecting bore; It is fixing promptly to have accomplished locking, and still, the defective of this twistlock is that the freight container parts are often heavy; Very easily cause the fracture of twistlock, the damaged replacing very seriously increased cost, wasted resource.And the top spring force on the twistlock is bigger, in releasing process, need push twistlock energetically and deviate from until barb, has increased working strength of workers, and usually need use 2 workmans and operate, and has also increased the human cost of enterprise.
In view of above-mentioned technological deficiency, it is a kind of simple in structure, easy to use to press for appearance, and locking is firm, anchor fitting and method of application thereof after the time saving and energy saving collapsible container locking.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that exists in the prior art, provide a kind of simple in structure, easy to use, locking is firm, anchor fitting and method of application thereof after the time saving and energy saving collapsible container locking.
To achieve these goals, the invention provides the anchor fitting after a kind of collapsible container locks, comprise lock body and shank; Wherein, the center of said lock body is provided with the conversion hole, and a side in said conversion hole is provided with fixed orifice; One side of said lock body outer rim is provided with arcwall face; Opposite side is a horizontal surface, and said horizontal surface is provided with lockhole, and said conversion hole, said fixed orifice, said lockhole and said lock body are one-body molded during fabrication.
Said conversion hole is circular, and said conversion is cut in said fixed orifice outside the hole, and said fixed orifice is square or equilateral triangle.
Be provided with fixed leg in the said fixed orifice, said fixed leg and said fixed orifice agree with between fixing, said fixed leg and the said conversion hole and flexibly connect.
Said lock body is U-shaped or semisphere, and the center in said lockhole, said fixed orifice, said conversion hole is on same horizon.
Further be provided with pin rod on the said shank, an end and the said shank of said pin rod are solidly connected, and the other end is set with pin plate, and said lockhole is a semicircle shape, and the radius of said lockhole equates with the radius of said pin rod.
Said pin plate is perpendicular to said pin rod, and said pin rod agrees with said lockhole captives joint, and said pin plate is close on the said lock body.
The said shank side's of being body or cylinder, said pin rod are cylinder or prism, and the horizontal surface of said pin plate and said lock body etc. are big.
For better solving technical matters to be solved, better realize the object of the invention, the present invention also provides the method for application of the anchor fitting after a kind of collapsible container locking, wherein, comprises the steps:
A, fixed leg is fixedly welded on the grillage of freight container, the fixed orifice of lock body is socketed on the fixed leg, the shank axle is connected on the end wall of freight container, make end wall folding or hold up after shank can agree with the lock body on the grillage,
B, shank with the first contact surface of lock body are: the contacting of arcwall face on pin plate and the lock body, and shank is pressed to lock body under the action of gravity of freight container end wall, and arcwall face is cut in pin plate outward; Lock body motion, fixed leg slide in the conversion hole, because of the effect of arcwall face; The lock body cw turns over and turn 90 degrees, and the shank conter clockwise turns over and turn 90 degrees, and pin rod slides in the lockhole and is connected; Pin plate is pressed on the horizontal surface of lock body, and fixed leg is returned to the position of fixed orifice, and fixed leg is fixed lock body; Lockhole is fixed pin rod, accomplishes fixing.
Perhaps, further comprise the steps:
C, fixed leg is fixedly welded on the end wall of freight container, the fixed orifice of lock body is socketed on the fixed leg, the shank axle is connected on the grillage of freight container, make end wall folding or hold up after lock body can agree with the shank on the grillage,
