Fig. 1 is the structural representation of a kind of embodiment of container door latch mechanism provided by the utility model;
Fig. 2 is the close-up schematic view at A place in Fig. 1;
Fig. 3 is the cutaway view of container door latch mechanism in Fig. 1.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the container door latch mechanism that the present embodiment provides, comprise chamber door 5 and end frame 6, end frame 6 is provided with three jam plates 1, and jam plate 1 offers through hole, and three jam plates 1 are from up to down evenly distributed on a sid frame 6.According to the actual height of freight container, the quantity of jam plate also can more than 3.The wallboard of chamber door 5 forms multiple trough portion 5-1 and multiple crest portion 5-2 by steel plate bending.Locking bar 2 is rotatably connected to and the 5-1 place of trough portion of holding frame 6 adjacent, locking bar 2 is provided with three latch hook 2-1, the installation position of latch hook 2-1 and the installation position one_to_one corresponding of jam plate 1.During container door locking, latch hook 2-1 and jam plate 1 cooperatively interact, and latch hook 2-1, through the through hole be opened on jam plate 1, forms three lock points of chamber door of container.
A strainer 3 is also provided with in the outside of chamber door of container 5.Strainer 3 selected in the present embodiment is straining ratchet, also can realize identical function with die forging strainer or chain strainer.As shown in Figures 2 and 3, the straining ratchet in the present embodiment comprises handle 3-1 and adjusting portion 3-2, and handle 3-1 and adjusting portion 3-2 are mutually vertical.A set collar 3-3 is respectively arranged with at the two ends, left and right of adjusting portion 3-2.Locking bar 2 is provided with a steady ring 3-4, the crest place 5-2 adjacent with locking bar 2 is fixedly installed one and remains silent D type ring 3-5, the set collar 3-3 of straining ratchet 3 one end is through described steady ring 3-4, and the other end is through D type ring 3-5, and straining ratchet 3 is fixedly connected between locking bar 2 and chamber door 5.
The principle of work of the container door latch mechanism provided in the present embodiment is as follows: when needing closure set loading door, reciprocally pulls handle 3-1, rotates continuously at the adjusting portion 3-2 uniaxially of the effect bottom ratchet wheel strainer 3 of pawl-and-gearing.In the process that adjusting portion 3-2 rotates, set collar 3-3 ceaselessly moves to the center of adjusting portion 3-2, and set collar 3-3 pulls locking bar 2 to rotate by steady ring 3-4, makes three latch hook 2-1 pass from the through hole jam plate 1 and lock simultaneously.If need chamber door of container to open, directly can rotate backward adjusting portion 3-2, namely set collar 3-3 can start outside movement, promotes steady ring 3-4 simultaneously and pulls locking bar 2 to rotate, locking bar 2 exits from the through hole jam plate 1 with moveable lock hook 2-1, realizes three lock points and opens simultaneously.Straining ratchet 3 is arranged on the downside of casing chamber door 5, and convenient operation personnel open or close chamber door convenient and strength-savingly.
The end frame 6 being provided with described jam plate 1 side is also provided with a spacing preiection 4-1, and spacing preiection 4-1 cooperatively interacts with the opening 4-2 being arranged on chamber door 5 side.Due to the mating reaction of spacing preiection 4-1 and opening 4-2, even if continue the handle pulling straining ratchet 3 after latch hook 2 pins jam plate 1, also can not continue to apply pressure and cause the parts of freight container to be damaged.
The container door latch mechanism that the present embodiment provides, by the cooperation of straining ratchet and locking bar, can control the latch hook of more than three or three simultaneously, and opening or closing of the multiple lock point of disposable control is convenient and swift, time saving and energy saving.Meanwhile, owing to being provided with the spacing preiection coordinated with chamber door one side opening on end frame, locking unlimited when can prevent from closing chamber door, destroys freight container parts.
The present embodiment provides a kind of freight container simultaneously, and this freight container is provided with container door latch mechanism as shown in Figure 1 to Figure 3, and the concrete structure of this container door latch mechanism see the record of above-described embodiment and accompanying drawing 1 to 3, can not repeat them here.
The inner surface edge of described chamber door of container 5 is provided with sealing joint strip, and sealing adhesive tape is preferably P type sealing joint strip.P type sealing joint strip can prevent the drainage of hermetic unit effectively.So if the goods carried in freight container has the risk of leak fluid, the freight container that the present embodiment provides also can play good sealing function, prevents liquid from oozing out.
In addition, the inside face of chamber door 5 of the freight container that the present embodiment provides and the door of container body are held level with both hands together, and the thickness of chamber door 5 is equal with longitudinal width of end frame 6.That is, different from traditional chamber door of container, the design of what the chamber door 5 of the freight container that the present embodiment provides adopted is exterior buckle type, the body of chamber door 5 does not take the unloading area of an end opening, farthest make use of space bearing goods in case.And P type adhesive tape can be pressed on end frame 6 by the outer button design of chamber door 5 firmly, further increases the sealing effectiveness of freight container.And the cooperation of spacing preiection 4-1 and opening 4-2, the extruding to adhesive tape when closing chamber door can being prevented, reducing the degree of deformation of adhesive tape, extend the service life of adhesive tape.
The freight container that the present embodiment provides, can realize controlling by the cooperation of a locking bar and straining ratchet the switch chamber door mode that Multiple locking point opens or closes quickly and easily, the chamber door of outer button coordinates the P type sealing joint strip at frame place, not only can utilize the available space in case substantially, good water-stop effect can also be realized.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
