Description
Technical field
The present invention relates to packaging field, particularly to the packing box of a kind of precision parts.
Background technology
Packing box is generally used for the circulation of goods, facilitates the turnover of goods, also exists most important in our life
Effect.Packing box has certain storage space, is commonly used to pack food that is multiple frangible or that be not easy to collision or object, works as bag
After in mounted box, article fill up, can only rely in case between article to bear against formation stable, but when when between article, space is more loose just
Can produce and rock, can cause the damage of article, existing conventional way time serious is to add vibrationproof implant, though operation is not multiple
Miscellaneous, but take time and effort, it is unfavorable for the saving of cost, the especially packaging to precision instrument.
In all items, precision instrument is the instrument that a class is higher to instrument precision requirement, and every precision instrument is going out
All through the test of performance during factory, but precision instrument can be rocked or clash into, seriously by various in the process selling transport
Affect the accurate performance of instrument.
In order to solve that the problems referred to above prior art has pointed out related art scheme, such as Chinese patent CN 105151482A
Disclosing " a kind of shock-proof packaging box ", including casing and case lid, described casing includes internal box and outer case, the sidewall of internal box
And gap is arranged between the sidewall of outer case, at least side sidewall of internal box be can the elastic plate that expands outwardly of arc-shaped deformation, institute
State shock-proof packaging box and also include the outer draw piece for drawing elastic plate to make it deform outward；Also include that the diapire being arranged on internal box is with outer
Between the diapire of casing and for the air spring of vibration damping.But its main purpose be article after being to make to be placed in packing box with
Having the metastable power of bearing against between article, form relatively stable placement effect, article will not form shifting relatively to each other
Move and produce collision, thus prevent from damaging.Also Chinese patent CN105151531A is had to disclose " a kind of packaging having shock-proof effect
Transport case ", including outer case be arranged in outer case and for the internal box of storing, the diapire of outer case and the end of internal box
It is provided with between wall for the damper unit to internal box longitudinal damping；It is additionally provided with on the sidewall of outer case outside internal box is formed
Wrapping and be used for the vibration-damped component to internal box oscillation crosswise vibration damping, vibration-damped component includes along the outer casing that outer case sidewall is circumferentially disposed
Be wrapped in outer casing in and stand tightly against in the damping body of outer case sidewall.
Both technical schemes above-mentioned the most effectively slow down the problem that article rock in casing, but such scheme all simply solves
Article do not rock relative to internal box, it is adaptable to the parts of decomposition, and the precision instrument assembled for local is the most inapplicable.
How to keep the standing of article not rock in the case of internal box is also had weak vibrations by prior art, then there is no correlation technique
Means.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides the packing box of a kind of precision parts, and it can be effectively ensured essence
Close instrument standing intact in transportation.
For realizing above-mentioned technical purpose, the concrete technological means that the present invention takes is, the packaging of a kind of precision parts
Box, including shell body and inner housing, uses the first damper mechanism to be connected between shell body with inner housing；Described inner housing include from
Supporting layer, cushion and the elastic layer set gradually in arriving outward；Described supporting layer is hard plate；Described cushion includes several
The second damper mechanism being uniformly arranged between supporting layer and elastic layer.
The technical scheme improved as the present invention, the inwall of shell body and the outer wall of inner housing are correspondingly arranged several and install
Groove；Described first damper mechanism installation by adhering is in mounting groove, and the thickness/height of described first damper mechanism is more than outward
The spacing of the mounting groove being correspondingly arranged in inner walls and inner housing outer wall.
The technical scheme improved as the present invention, described first damper mechanism is shock-absorbing spring, air cushion or elastic ball；The
Two damper mechanisms are shock-absorbing spring, air cushion or elastic ball.
The technical scheme improved as the present invention, also includes that several sponge liquid glue, described sponge liquid glue are positioned over
In gap between precision component and elastic layer.
The technical scheme improved as the present invention, described hard plate is PVC hard plate.
The technical scheme improved as the present invention, described elastic layer is that each material using following weight portion is prepared from:
Unsaturated group cage-type silsesquioxane 1-4 part
EVA resin 4-16 part
Ethylenically unsaturated polyisocyanate 4-16 part
Polyether polyols ester 4-16 part
Unsaturated polyester resin 2-8 part.
The technical scheme improved as the present invention, in described EVA resin, VA content is 30%-50%.
The technical scheme improved as the present invention, described protecting film uses following steps to be prepared from, particularly as follows: a,
At a temperature of 100-150 DEG C, after melted for EVA resin, add unsaturated group cage-type silsesquioxane, obtain pre-after mix homogeneously
Goods；B, ethylenically unsaturated polyisocyanate and polyether polyol are simultaneously introduced mixing and stirring in prefabrication, and
React 0.5-5h under the vacuum of 120-130 DEG C, obtain intermediate products；C, it is 60-90 DEG C in 1.5-2 normal atmosphere, temperature
Under conditions of unsaturated polyurethanes added in intermediate products and mix homogeneously, after standing 3-5h, compression molding obtains protecting film.
Beneficial effect
The present invention, by arranging the first damper mechanism between shell body and inner housing, effectively slows down outside to packing box inner housing
Vibration, cushion and the elastic layer in inner housing positioned inside avoids the vibration of inner housing to precision parts the most completely
Vibration.
Detailed description of the invention
Purpose and technical scheme for making the embodiment of the present invention are clearer, below the technical scheme to the embodiment of the present invention
It is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention rather than whole realities
