Description

Freight container lock on the flat truck

Technical field

The utility model relates to flat truck, relates in particular to the equipped used lockset of fixed set vanning of flat truck.

Background technology

Existing semi-mounted flat truck generally is designed to the many usefulness of a car, both can transport ordinary goods and also can transport standard container.Therefore, the lockset that needs equipped fixed set vanning usefulness on the flat truck, this lockset is made up of lock and tapered end, this lock must be flush-mounted in flat board and this tapered end must be lifting mode, not overslaugh goods is placed so that can descend during flat truck transportation ordinary goods, can rise during delivery container and cooperates with the container base corner fittings and freight container is fixed.

A kind of conventional structure of existing lock is made up of panel and lock box two parts, and panel is welded into i shaped cross section by dull and stereotyped with three press strip plates; Lock box is welded into box-like by the flat board of four different sizes.This structure exists blanking, the dress of abandoning is very loaded down with trivial details with production process such as welding, and forming dimension is difficult to the problem accurately controlled, thereby causes productive costs height, production efficiency low.

The utility model content

The purpose of this utility model proposes the freight container lock on a kind of flat truck, makes defective loaded down with trivial details and that the assembling and positioning size is inaccurate to solve existing lock.

To achieve these goals, the utility model provides the lock of the freight container on a kind of flat truck, be flush-mounted in the vehicle frame plane of flat truck, comprise a panel, the lock box of offering at least one round keyhole on this panel and being provided with in corresponding each lockhole place, the back side of this panel, this lock box comprises: vertically this lockhole of this panel and cross-over connection and the two straight walls that extended in parallel downwards by this lockhole place and the circular arc wall that is connected between these two straight walls and extends downwards along the partial arc edge of lockhole, this panel and this lock box are one-body molded, this two straight wall is provided with perforate and fluting respectively on corresponding position, the position of this fluting is near this panel, and the position of this perforate is away from this panel and be positioned at the end away from this circular arc wall of this straight wall.

Compared with prior art, freight container lock on the flat truck of the present utility model because panel and lock box are one-body molded and have said structure, are made man-hour and is improved the lockset accurate positioning thereby can reduce workpiece, thereby can reduce production costs, enhance productivity and promote product design.

Fig. 2 A and 2B be freight container on the flat truck of the present utility model with the structural representation of lock embodiment two, wherein, Fig. 2 A is a front view, Fig. 2 B is that A-A among Fig. 2 A is to cutaway view.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is given elaboration further.

Freight container on the flat truck of the present utility model lock embodiment one, it is the vehicle frame plane that is flush-mounted in flat truck, shown in Figure 1A to 1E, this lock comprises a panel 1 and a lock box 2, offer a lockhole 14 on the panel 1, at these lockhole 14 places, in the back side of panel 1 lock box 2 is set accordingly, this panel 1 and lock box 2 are by for example the as cast mode is one-body molded.

Panel 1 comprises a flat board 11, and panel 1 is established upwards flange 12 in three limits dull and stereotyped 11, that link to each other, and this three limit comprises first limit 111 in the middle of being positioned at and is positioned at two sides 112,113 of these both sides, first limit.Panel 1 also also is provided with to lower flange 15 in this three limit, thereby makes the cross section of panel 1 be approximate I-shape.

Because the bottom surface of corner fittings under the freight container (figure does not show) is lower than the bottom surface (being that corner fittings and crossbeam exist diff-H) of crossbeam, the height dimension of flange 12 is the 12-14 millimeter, and the upper surface of flange 12 is concordant with the vehicle frame plane, thereby whole dull and stereotyped 11 relative vehicle frame plane be depression 12-14 millimeter so that cooperate with the corner fittings of bottom under the freight container.

This panel 1 also is provided with the shirt rim 13 of outwards being stretched by the upper end of these three flanges that make progress, wherein, the upwards shirt rim of flange on first limit 111 stretches out along whole first limit 111, the upwards shirt rim of flange on two sides 112,113 then is that the part along two sides 112,113 stretches out, and this design is convenient panel 1 and vehicle frame plane to be pieced together one.

Lock box 2 comprises: the two relative

straight walls

21,22 that extend downwards by lockhole 14 places and be connected in 21,22 on two straight walls and along the partial arc edge of lockhole 14 circular arc wall 23 of extension downwards, this structure can match with the outline of tapered end 3 well.Two

straight walls

21,22 are equipped with perforate 211,221 on corresponding position, two

straight walls

21,22 on corresponding position, be equipped with the fluting 24, relatively, fluting 24 position is near panel 1, and the position of perforate 211,221 is then away from panel 1 and be positioned at the end away from circular arc wall 23 of

straight wall

21,22.

Under the general state, shown in Fig. 1 D, tapered end 3 is in and falls the position, is concealed in the lock box 2, is held by the dowel bolt 4 in the perforate 211,221 that is inserted in lock box 2.Shown in Fig. 1 E, when tapered end 3 is in raise-position, fluting 24 by lock box 2 tops cooperates with the flange (figure does not show) that the lock of tapered end is provided with on one's body, rotatable tapered end 3 and make this flange stretch into this fluting 24 and fixing tapered end 3, at this moment tapered end 3 is to stretch out in the vehicle frame plane, and turning handle 5 just can be controlled tapered end 3 and be in and fall position or raise-position, to satisfy the locking and the location of tapered end 3 and container angle, secure fixation is guaranteed traffic safety when making freight container traffic on vehicle frame.

The circular arc wall 23 of lock box 2 and arc circular arc wall 23 corresponding with first limit of panel 1 leans first limit 111 of nearly

panel

1, and 21,22 on two straight walls of lock box 2 are corresponding with two sides 113,112 of panel 1 respectively.

It can also be seen that from Fig. 1 C, also be provided with two lightening holes 212,213 on the straight wall 21 of lock box 2.Obviously, can offer lightening hole equally on the straight wall 22 of lock box 2; And, the depth dimensions of the circular arc wall 23 of lock box 2 is less than the depth dimensions of two

straight walls

21,22, this is to limit the lock body to get final product because the outline of 23 need of circular arc wall and tapered end matches, and will offer the perforate 211,221 that qualification tapered end low level is used on two

straight walls

21,22, and the position of perforate 211,221 wants dark than the extreme depth of circular arc wall 23.

Freight container on the flat truck of the present utility model lock embodiment two, shown in Fig. 2 A and 2B, the difference of itself and the foregoing description one is the number of lockhole and lock box: in embodiment one, be that the central authorities at panel 1 have offered a lockhole 14, this lockhole place has disposed a lock box 2; In the present embodiment, be that the central authorities at panel 1 have offered two

lockholes

14,16, each lockhole place has disposed a lock box 2.

Foregoing; it only is preferred embodiment of the present utility model; be not to be used to limit embodiment of the present utility model; those of ordinary skills are according to main design of the present utility model and spirit; protection domain of the present utility model can carry out corresponding flexible or modification very easily, so should be as the criterion with the desired protection domain of claims.
