Description

The Turnover Box heating cushion

Technical field

The utility model relates to a kind of heating cushion, or rather, is a kind of Turnover Box heating cushion.

Background technology

Turnover Box of the prior art does not have heating function, the temperature that keeps relative stability for the later stage that is implemented in goods transport; Often adopt the method that adds heat-insulation layer to goods packing, but this complicated operation is difficult to the heat insulation effect that reaches desired after its transportation; And there are a lot of goods not need insulation; Only need heat up in the final stage of transportation and can be effective, not only cost be higher to add heat-insulation layer, and weak effect.

Chinese invention patent ZL 92101889.4 discloses a kind of heat-insulation going-around box for food; It comprises casing, and tank material is a high-magnesium glass fibre reinforced plastic honeycomb plate, and box house is divided into two sections; Bringing-up section and placement are heated the food section; One grate is arranged between two sections, and the bringing-up section bottom is placed with termite, and the termite top has to isolate uses cloth.But this Turnover Box, complex structure, production and use cost are higher.

China utility model patent ZL 02228881.3 discloses a kind of quartz conductor milk turnover antistaling box, belongs to semiconductor refrigerating/thermal technology field, and the user who is suitable for doing delivery at door deposits the milk box of fresh milk.It mainly is made up of casing, quartz conductor economic benefits and social benefits pile sheet, power supply, change-over swith and radiating gill; Casing is divided into three layers, outer is the thermal insulation shell, and internal layer is for leading warm inwall, shell and to lead between the warm inwall be heat-insulation layer; Temperature conducting block is that mechanical fixation such as screw thread are connected with leading warm inwall; Two faces of quartz conductor economic benefits and social benefits pile sheet fit tightly with temperature conducting block and radiating gill respectively, and the lock bolt through temperature conducting block and radiating gill is fixed between the two.But the productive costs of this antistaling box is higher, and is fragile, and heating effect is poor.

The open CN 200710012492.6 of Chinese invention patent discloses a kind of turnover pallet; The wood load that below base plate, base plate, connects is formed; Wood load and the cooresponding position of base plate have connecting bore; Connecting bore the inner of base plate is inlaid with nut, and connecting bore and nut that the screw rod of bolt or screw passes the wood load are connected.The screw rod end of bolt or screw can conveniently be screwed into nut, with wood load and base plate fixed combination together, constitutes pallet; Bolt or the screw front end nut of back-outing is removed interconnecting between base plate and the wood load, and the smooth base plate of a piece that separates can make things convenient for closely with a root wood load of separating and overlaps, and has significantly reduced the volume of recovery, greatly reduces the expense of turnover.But this turnover pallet does not have heating arrangement, can not heat goods.

The utility model content

The utility model mainly is to solve the existing in prior technology technical matters, thereby Turnover Box heating cushion a kind of simple in structure, safe and reliable, easy to use is provided.

The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: a kind of Turnover Box heating cushion; Described heating cushion be arranged on Turnover Box base plate above; The size of described heating cushion and the size of base plate adapt; Described heating cushion is made up of electric heating piece and fire-retardant heat insulation carpet; The size of the size of described electric heating piece and fire-retardant heat insulation carpet adapts, and described electric heating piece is connected with temp control switch, Thermal Cutoffs, earth leakage protective device and plug in order.

As the preferable Turnover Box preferred embodiment of the utility model; The structure of described electric heating piece is divided three layers: lower floor's aluminum foil and adhesive tape; Middle level heating electric wire and upper strata aluminum foil and adhesive tape; Described lower floor aluminum foil and adhesive tape and upper strata aluminum foil and adhesive tape ground connection, described lower floor aluminum foil and adhesive tape and upper strata aluminum foil and adhesive tape stick on middle level heating electric wire and form electric heating piece together.

As the Turnover Box preferred embodiment of the utility model, the high temperature resistant degree of described fire-retardant heat insulation carpet is 100 ℃.

Therefore, the heating cushion of the utility model can be fixed on as required Turnover Box base plate above, advantage is simple in structure, and is safe and reliable, easy to use, can heat continuously goods in the later stage of shipping goods.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the hierarchy scheme drawing of the electric heating piece of the utility model;

Fig. 2 is the structural representation of the electric heating piece of the utility model;

Fig. 3 is the structural representation of the heating cushion of the utility model;

Fig. 4 is arranged on the structural representation above the base plate of Turnover Box for the heating cushion of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

The utility model provides a kind of functions such as electromagnetic wave shielding, earth leakage protective, overtemperature prote that have, and is safe and reliable, convenient, Turnover Box heating cushion simple in structure.

As shown in Figure 4, a kind of Turnover Box heating cushion, this heating cushion 2 be arranged on this Turnover Box base plate 1 above, the size of the size of this heating cushion 2 and base plate 1 adapts.
