Technical field
It the utility model is related to Turnover Box, more particularly to a kind of Turnover Box double bottom structure.
Background technology
With china socialism's market economy system foundation, the quickening of world economic integration process and science and technology
Rapid development, material flow industry is as the important means for improving the market competitiveness and enterprise core competitiveness.Turnover Box, make
For the carrier of logistics, it is widely used always for a long time.
In order to increase bearing, the bottom of existing Turnover Box is mostly double-decker, for details, reference can be made to utility model patent
CN201951774U, which disclose the bottom plate of casing includes upper plate and lower shoe, is connected between upper plate and lower shoe
Have a reinforcement, reinforcement includes upper reinforcement and lower reinforcement two parts, upper reinforcement, upper plate be with wall box one into
Type, the lower reinforcement is integrally formed with lower shoe, and the lower shoe and upper plate pass through lower reinforcement and upper reinforcement
Muscle welds and realizes being connected between the two.Above-mentioned prior art, bearing is preferable, but this double bottom structure needs
Welding, production process is complicated, and the cost of production is higher.
The content of the invention
The utility model purpose is to provide a kind of Turnover Box double bottom structure, on the premise of bearing is ensured reduce into
This, improves production efficiency.
To reach above-mentioned purpose, the technical solution adopted in the utility model is:A kind of Turnover Box double bottom structure, including one
Inner bottom plating, the parallel beneath of the inner bottom plating are disposed with the Outer Bottom Plating of closed loop frame-shaped, and the closed loop frame of the Outer Bottom Plating is around inner bottom plating
Circumferentially, the inner rim of Outer Bottom Plating is along with being connected with the circumferential muscle of one week between inner bottom plating, and the plate face of Outer Bottom Plating with it is interior
Connected between bottom plate with spaced peripheral reinforcement;And it is spaced in the inside vacant space of the closed loop frame of the Outer Bottom Plating
Provided with multiple central ribs, the top of these central ribs and the bottom surface of inner bottom plating connect;It is also, the inner bottom plating, outer
Bottom plate, circumferential muscle, peripheral reinforcement and central rib connect for integrated through injection molding.
In such scheme, the central rib is made up of horizontal bar and longitudinal rib, and the horizontal bar and longitudinal rib are vertical
Interconnection, and the both ends end of horizontal bar and longitudinal rib is connected on circumferential muscle.
In such scheme, the circumferential muscle can be one week muscle of closing or that does not close lead to provided with through hole
Slot structure.
Design principle of the present utility model and the effect brought are as follows:The present utility model people, which has taken into full account, to be molded into
The each side such as type technique and mold design, and a kind of double bottom structure for being capable of integrated injection molding is have devised, the bilayer
Bottom structure can integrated injection molding, avoid welding, it is easy to make quick, and its load-bearing property and prior art weld formula
Double bottom structure it is substantially suitable, remain the excellent advantage of the bearing of double bottom.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model:
Embodiment:Referring to shown in Fig. 1 ~ Fig. 4:
A kind of Turnover Box double bottom structure, including an inner bottom plating 1, the parallel beneath of inner bottom plating 1 are disposed with closed loop frame-shaped
Outer Bottom Plating 2, the closed loop frame of the Outer Bottom Plating 2 be around inner bottom plating 1 circumferentially, the inner rim of Outer Bottom Plating 2 along between inner bottom plating 1
The circumferential muscle 3 of one week is connected with, and is connected between the plate face of Outer Bottom Plating 2 and inner bottom plating 1 with spaced peripheral reinforcement 4;
And multiple central ribs 5 are interval with the inside vacant space of the closed loop frame of the Outer Bottom Plating 2, these central ribs 5
Top be connected with the bottom surface of inner bottom plating 1;Also, the inner bottom plating 1, Outer Bottom Plating 2, circumferential muscle 3, peripheral reinforcement 4 and in
Heart reinforcement 5 connects for integrated through injection molding, i.e., the present embodiment double bottom structure is integrally injection moulding integrated molding.
Specifically, the central rib 5 is made up of horizontal bar 51 and longitudinal rib 52, and the horizontal bar 51 and longitudinal rib 52 hang down
Straight interconnection, and the both ends end of horizontal bar 51 and longitudinal rib 52 is connected on circumferential muscle 3.
Specifically, the Turnover Box as Fig. 1-4 citing the present embodiment is applied is the rectangular box of an injection, but is only for lifting
Example, in practice, the present embodiment can also apply other Turnover Boxes, for example folding Turnover Box, the Turnover Box of hollow sheeting homing position type
Deng.
As shown in Figure 2,3, 4, the inside vacant space of the closed loop frame of the Outer Bottom Plating 2 is rectangle, is alternatively it in practice
His shape, such as circular, polygon.
The present embodiment double bottom structure can integrated injection molding, avoid welding, it is easy to make quick, and its load-bearing
Performance is substantially suitable with the double bottom structure of prior art weld formula, remains the excellent advantage of the bearing of double bottom.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, the scope of protection of the utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
It is interior.
