The specific embodiment
Below we come container-trailer of the present utility model made further of the structure of angle lock and function of use with specific embodiment in conjunction with the accompanying drawings and elaborate, but can not limit protection domain of the present utility model with this.
Trailer of the present utility model angle lock is because will adapt to the container of at least two kinds of different sizes, so need lock the lock pin position at the angle and make special processing, the position that to make its lock pin can appear at two center to center distance at least be 46mm, and corresponding with position, container angle hole on the trailer.Like this, at different containers, the lock pin that the operator can select to be fit to the position is mated.
At these situations, we have designed the form of the container-trailer angle lock of at least three kinds of form of structure, describe in detail with three embodiment below:
Embodiment 1
Referring to Fig. 4～shown in Figure 9, the utility model angle lock comprises housing 1, lock pin 2, handle 3 and card 4.Housing 1 is made up of sleeve 11 and the side plate 12 that is fixed on cartridges sides, and sleeve is provided with the trepanning that holds lock pin 2, and side plate is provided with the slightness hole 13 that connects with trepanning, and this slightness hole 13 is parallel to the axis of sleeve.Above-mentioned handle 3 passes the slightness hole 13 of side plate, with the lock pin 2 vertical flexible connections in the sleeve, thereby realizes handle 3 and lock pin 2 interlocks.
Length direction along slightness hole 13 promotes handle, and lock pin 2, handle 3 are moved along sleeve, through hole respectively, lock pin 2 is stretched out or the indentation sleeve.The length of slightness hole 13 equals the flexible stroke of lock pin 2, and the height of sleeve 11 is greater than the flexible stroke of lock pin 2, prevents that lock pin 2 from deviating from from sleeve in moving process.
One end and the side plate 12 of above-mentioned card 4 are pivotally connected, the free end of the other end for pivoting, locating slot 41,42, two locating slots 41,42 that card 4 is provided with fixed handle 3 positions respectively with side plate 12 on slightness hole 13 stacks constitute two permanent positions of handles 3.The position of locating slot 41,42 on card stretch out with lock pin 2 respectively or during the indentation sleeve two location points at handle place corresponding.When lock pin 2 stretches out or during the indentation sleeve, rotation card 4 is placed on the handle 3 locating slot 41 or locating slot 42, thus fixedly lock pin 2 and handle 3.Be the U-lag of toppling near the locating slot 41 of card 4 pivot pin ends, and be the arc notch at free end end angle away from the locating slot 42 of pivot pin end.
When angle lock need be between first state of 2260mm and second state that center to center distance is 2352mm during conversion in center to center distance, earlier with lock pin 2 indentation sleeves, make the lock pin 2 and the link position of handle 3 spill the cover tube bottom, take out the pin that is connected between lock pin 2 and the handle 3, lock pin 2 is turned over turnback, recover in the sleeve, load onto pin more again and connect lock pin 2 and handle 3, as Fig. 6 and shown in Figure 8.In first state and second state, the change in displacement of angle lock lock pin is 46mm.
The embodiment of the technical program only be a kind of structure simple relatively, use embodiment relatively easily, be not the unique scheme that realizes the utility model purpose.
As shown in Figure 10 and Figure 11, adopt ball to be connected in the present embodiment between lock pin 2 and the handle 3, trepanning on the case follower 11 and the lock pin in the trepanning 2 are sold bodies and are all adopted cylinder design simultaneously, and between lock pin and sleeve detent mechanism are set.Wherein a kind of design of detent mechanism is in the pin body both sides of lock pin 2 groove 24 to be set, trepanning sidewall correspondence at sleeve is provided with groove 13, the common alignment pin of planting (figure does not show) in lock pin groove 24, sleeve groove 13 makes lock pin 2 keep relative static with sleeve 11 then.During switching state, extract alignment pin, then can directly rotate the lock pin switching state, avoid installing and removing lock pin and handle, improve the efficient that angle lock state switches, use more convenient.
The fixed form of handle is identical with embodiment 1 in the present embodiment, does not do repetition at this.
What adopt in the present embodiment is the angle lock construction design of twin-lock pin, and as Figure 12～shown in Figure 14, the angle is locked and included two lock pins, and each lock pin is corresponding to a link position point.On concrete structure design, angle lock includes a housing 1, two lock pins 2 and two handles 3, two cards 4, housing 1 is made up of sleeve 11 and the side plate 12 that is fixed on cartridges sides, sleeve 11 is provided with two trepannings that hold lock pin, side plate 12 is provided with two slightness holes 13, the corresponding one group of lock pin of each trepanning, handle, card, slightness hole, slightness hole 13 connects with trepanning, lock pin 2 is vertical in-line structure, and handle 3 passes slightness hole 13 and vertically is connected on the lock pin of being located in the trepanning 2; Card 4 is fixed on the housing 1, is provided with the locating slot that is used for fixing handling position on card.
Center to center distance in the present embodiment between two lock pins of angle lock is 46mm.In the use, only need select which lock pin to use according to the model of container, promote handle then this lock pin is risen, the lock pin of rise extend in the corner fittings hole of container and gets final product, and other lock pin maintenance is contracted in sleeve, is in dormant state.In like manner, when the container corresponding with the another lock pin need be located, then rise and use this, another then withdraws stand-by.
The fixed form of handle is identical with embodiment 1 in the present embodiment, does not also do repetition at this.
Housing among above-mentioned three kinds of embodiment can also adopt integrated design, directly with sleeve and side plate integrated molding except adopting the split design of being made of sleeve 11 and side plate 12.
The utility model container-trailer, comprise roof beam structure body with front beam and rear cross beam, be provided with wheel near below the roof beam structure body of rear cross beam one end, front beam, rear cross beam two ends are equipped with angle lock c, and the lock pin on the lock c of angle has at least two can select a link position point that is connected with container angle.As Figure 15 and shown in Figure 16, be assembling and the result of use of on the front beam of the utility model trailer, using angle lock embodiment 1.When the container angle pitch-row was 2260mm, angle lock c adopted first state as shown in figure 15; When the container angle pitch-row was 2352mm, angle lock c adopted second state as shown in figure 16.Lock c in angle can unify to adopt any among above-mentioned three kinds of embodiment, also can several mixing use.
For improving the trailer versatility, the utility model is according to the corner fittings pitch-row of different size container, calculate the displacement of pin head in sleeve of angle lock, after making the pin head adjustment position of angle lock on the trailer, it is identical with the corner fittings pitch-row of a certain set of specifications vanning that center to center distance between the lock pin head of angle still keeps, the container that guarantees different size is positioned on the trailer, and trailer angle lock all has suitable link position point and cooperates with container angle.
