Abstract

The utility model relates to a semi-automatic intermediate lock for a folding container. The semi-automatic intermediate lock comprises a steel rope handle (1), a bolt and nut (2), a lock shaft (3) and shell bodies (4). The lock shaft (3) is tightly clamped in the shell bodies (4) through the bolt and nut (2). The shell bodies (4) comprise a left shell body and a right shell body. The steel rope handle (1) is inserted into the middle gap of the shell bodies (4) in a penetrating way. Two sides of the middle gap are respectively provided with a tilted clamping groove. A torsional spring is winded on the lock shaft (3). One straight end of the torsional spring is pressed in the groove between the two shell bodies, and the other hook end of the torsional spring is hooked on a boss of the lock shaft (3). A coned lock is arranged above the lock shaft and below the lock shaft respectively (3). The shell bodies (4) are provided with a flange surface with a thin plate structure. The semi-automatic intermediate lock for the folding container can solve the problem that the locking device of the folding container is convenient and steady to assemble and disassemble.

Description

Lock in the middle of the S. A. that a kind of collapsible container is used

Technical field

The utility model belongs to the latching device field, particularly relates to the middle lock of S. A. that a kind of collapsible container is used.

Background technology

Collapsible container is in the empty van transportation claims, because of volume after folding less relatively (highly reducing), the height ability of the folding back of plurality of portable case stacking is with respect to the height of a standard container, so just improve the empty van conveying efficiency of folding carton greatly, also greatly reduced the empty van traffic cost of folding carton.But this special way of stacking just requires the flange face thickness of the used lock of stacking littler than the routine, and the flange face thickness of conventional lock is

Therefore, the stacking between the collapsible container needs a kind of both safety, and operation is convenient again, and structure is reasonably locked again.

Summary of the invention

Technical problem to be solved in the utility model provides the middle lock of S. A. that a kind of collapsible container is used, the same with the bottom-to-top-height behind the solution plurality of portable formula container folds stacking with the height of standard container, realize the high efficiency transportation of this collapsible container, reduce the case traffic cost of collapsible container sky simultaneously.

The technical scheme that its technical matters that solves the utility model adopts is: lock in the middle of the S. A. that provides a kind of collapsible container to use, according to calculating, (flange face is thick for the flange face aspect ratio routine of lock ) little, comprise steel cable handgrip, screw bolt and nut, lock shaft and housing, described lock shaft is clamped in the housing by screw bolt and nut, described housing divides left shell and right shell body, described steel cable handgrip interts in the gap, middle part of housing, the both sides in space, middle part have an oblique draw-in groove respectively, are wound with torsion spring on the described lock shaft, and described housing has the flange face of thin-slab structure.

Described torsion spring is held in the groove that is pressed between the two housings always, and another gib head end hook is on the boss of lock shaft, and described lock shaft upper and lower has bevelled tapered end respectively.

Beneficial effect

The utility model is easy to use, stable, can help to realize that the bottom-to-top-height after the folding laggard windrow of plurality of portable formula is piled up neatly equals the height of a standard container.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

As Fig. 1, Fig. 2, shown in Figure 3, lock in the middle of the S. A. that a kind of collapsible container is used, according to calculating, (flange face is thick for the flange face aspect ratio routine of lock

) little, comprise steel cable handgrip 1, screw bolt and nut 2, lock shaft 3 and housing 4,4 fens left shells of housing and right shell body, described lock shaft 3 is clamped in the housing 4 by screw bolt and nut 2, described steel cable handgrip 1 interts in the gap, middle part of housing 4, the both sides in space, middle part have an oblique draw-in groove 5 respectively, are wound with torsion spring 6 on the described lock shaft 3.

Described torsion spring 6 is held in the groove that is pressed between the two housings always, and another gib head end hook is on the boss of lock shaft 3, and described lock shaft 3 upper and lowers have bevelled tapered end respectively.

Need only during use and make tapered end or lower lock head Unscrew by steel cable handgrip 1, pack into behind the corresponding corner fittings, unclamp steel cable handgrip 1, allow the tapered end contrarotation reset, twistlock and freight container link together, corner fittings on fastening another freight container of want or hatch cover corner fittings are inserted the similar spiral tapered end, just can realize that fast automatic pinning is fastening.

Operation instructions:

1. locking state: promptly not in draw-in groove 5, this moment, this lock was in locking state to steel cable handgrip 1 in the raw;

2. the case process falls: by last tapered end inclined-plane, lock shaft 3 rotation back freight containers fall, and locking automatically resets after lock shaft 3 rotates by torsion;

3. unblank: pulling steel cable handgrip 1, the steel cable handgrip is sticked into draw-in groove 5, this moment, tapered end was opened.

4. lifting container takes off lock.

Claims (2)

1. lock in the middle of the S. A. used of a collapsible container, comprise steel cable handgrip (1), screw bolt and nut (2), lock shaft (3) and housing (4), it is characterized in that: described lock shaft (3) is clamped in the housing (4) by screw bolt and nut (2), described housing (4) divides left shell and right shell body, described steel cable handgrip (1) interts in the gap, middle part of housing (4), the both sides in space, middle part have an oblique draw-in groove (5) respectively, be wound with torsion spring (6) on the described lock shaft (3), described housing (4) has the flange face of thin-slab structure.

2. lock in the middle of the S. A. that a kind of collapsible container according to claim 1 is used, it is characterized in that: described torsion spring (6) is held in the groove that is pressed between the two housings always, another gib head end hook is on the boss of lock shaft (3), and described lock shaft (3) upper and lower has bevelled tapered end respectively.
