The utility model is characterized in that the lower part of a lock rod 12 of a lock shaft 1 is provided with a straight slot or a cross slot, and a lock head of the lock shaft 1 has double inclined planes; the lock rod 12 of the lock shaft extending into a lock seat 2 is connected with a torsion spring 3 arranged on the lower part of the lock seat 2 through a nut 11; the torsion spring 3 is a metal spring which is composed of 1-5 metal spring wires 9 and an iron ring 8. The utility model can be positioned and can also be fixedly locked, stability is good at a high or a low temperature, fatigue life is long, maintenance is convenient, manual operation is not needed in use, and loading and unloading automatization can be realized.

Description

Freight container medal spring Fully-automatic lock

The utility model relates to a kind of positioning and fastening arrangement of freight container, especially freight container medal spring Fully-automatic lock.

At present, the positioning and fastening arrangement of automobile-used freight container manual lockset and the positioning boss locksets of adopting more.Manually lockset needs to use manual manipulation in handling process, thereby has increased unnecessary trouble to the alongshoreman.The positioning boss lockset has only positioning function, does not have locking function, just can only control sets vanning the rocking of horizontal surface, can not lock vertically and beat.When car occurred than strong motion in transportation, freight container just can topple.Chinese patent 972471154 discloses a kind of " freight container Fully-automatic lock ", and this freight container Fully-automatic lock is a kind of India-rubber spring Fully-automatic lock, though it can solve foregoing problems effectively, and under low temperature and high temperature running condition, the rubber performance instability; During low temperature, the case power that falls increases, and might cause the deadweight of empty van not open lockset effectively, and coupling mechanism force reduces again during high temperature.And the India-rubber spring life-span is lower, and operating cycles is short, causes maintenance cost to increase.

The purpose of this utility model provides a kind of freight container medal spring Fully-automatic lock, is medal spring by changing India-rubber spring, solves the problem of India-rubber spring unstable properties under the low temperature and the condition of high temperature, improves the fatigue life of torsion spring.

Concrete scheme of the present utility model is: comprise lock shaft, lock, torsion spring, safety pin, the nut of double inclined plane tapered end, it is characterized in that: the bottom of the locking bar of A. lock shaft has flat recess or cross recess; B. the locking bar of lock shaft stretches into lock and passes nut and be connected with the torsion spring of the lock bottom of packing into; C. torsion spring is a kind of medal spring.

The utility model is when vanning, and the case angular alignment lock shaft head with freight container puts down freight container, and the container angle hole acts on lock shaft head the first half curve, relies on the deadweight at case angle to make the lock shaft rotation, and the freight container entrucking puts in place when lock shaft rotates to open position.At this moment, lock shaft reverses rapidly under the effect of torsion spring and automatically resets, and forms the locking state to freight container.The utility model lifts by crane with weight-lifting equipment when getting case, and at this moment the hole, angle of freight container acts on the head part curve of lock shaft, relies on the lifting force of weight-lifting equipment to make the lock shaft rotation, takes out freight container.After freight container took out, under the effect of torsion spring, the rapid return of lock shaft formed locking state again.

Adopt such scheme, can locate, can lock again; Still stable in high and low temperature state locking performance, fatigue life is long, and the maintain and replace consumable accessory is convenient, and can not cause damage to lockset and vehicle; In use need not be hand-manipulated, can realize the automation of loading and unloading.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the birds-eye view of torsion spring 3 among Fig. 1;

Fig. 4 is the assembling situation of the utility model and freight container 7.

By Fig. 1, Fig. 2, Fig. 3 as can be known: the utility model is made up of lock shaft 1, lock 2, torsion spring 3, bottom 4, safety pin 5, installing frame 6 etc.; Wherein the tapered end of lock shaft 1 is the double inclined plane structure; Torsion spring 3 is sleeved on the lock shaft 1, and its outer ring iron hoop 8 is connected with safety pin 5, and this safety pin 5 stretches out outside the lock 2; Bottom 4 is positioned at the bottom of lock 2, i.e. the below of lock shaft 1 and torsion spring 3.Structural feature of the present utility model is: the bottom of the locking bar 12 of A. lock shaft 1 has flat recess or cross recess; B. the locking bar 12 of lock shaft stretches into lock 2 and passes nut 11 and be connected with the torsion spring 3 of lock 2 bottoms of packing into; C. torsion spring 3 is a kind of medal springs.

As shown in Figure 1: torsion spring 3 is to be coiled on the cross recess of lock shaft 1 bottom.

As shown in Figure 3: torsion spring 3 is a kind of medal springs of being made up of 1～5 medal spring silk 9 and iron hoop 8; Medal spring silk 9 is coiled in the iron hoop 8.Have pin hole 10 on iron hoop 8, safety pin 5 inserts in the pin hole 10.

As shown in Figure 2: the front end face at installing frame 6 is provided with block 13 and bolt 14.When needing maintenance or changing the consumable accessory lock, can unclamp bolt 14, rotary block 13 makes block 13 no longer block lock 2, outwards spurs safety pin 5 and just can realize.

As shown in Figure 4: the annexation of the utility model and freight container 7 is that the case angle of freight container is installed in and locks.Have only the top of tapered end 1 and lock 2 to pass freight container 7 base plates in the utility model, installing frame 6 and safety pin 5 are positioned at the below of freight container 7, therefore, can resemble when needing the maintain and replace consumable accessory and draw drawer type ground that lockset is pulled out, and can not cause damage to lockset and vehicle.
