Abstract

The invention provides a combined tray set. The set comprises a supported object and a tray body, wherein a plurality of electromagnets are embedded on the tray body, and are coupled with and controlled by a human body touch switch; the human body touch switch comprises a switch unit; the switch unit is coupled between a battery pack and the electromagnets; when a human body touches the human body touch switch, the switch unit is connected to electrify the electromagnets to generate attractive force for the supported object; when the human body leaves the touch switch, the switch unit is disconnected to enable the electromagnets to lose power. Normally, when the human body touches the position of the human body touch switch, the electromagnets are powered by the battery pack, so that the supported object can be directly fixed on the tray to achieve a fixed effect, the consignment can be convenient, human hands mush leave the tray when the supported object needs to be taken, the taking operation can be convenient, and the convenience can be improved.

Description

A kind of built-up pallet external member

Technical field

The present invention relates to life appliance, be used for manpower delivery object, particularly a kind of built-up pallet external member.

Background technology

Pallet is to be used to provide article to place, and plays one way of life, food and drink, the medical instruments of the effect of convenient carrying.

Food service tray is a kind of container that food and raw and fresh food are deposited, and can, with insurance film parcel, be simple and easy to convenient. Conventionally the raw material that food service tray uses has two kinds of PP food service tray or PE food service trays, for example, be used for holding of dish in catering field.

And medical tray is used for placing medicine equipment;

There is some problems in existing pallet, due to when the staff transportation tray, easily occurs the problem of rocking, if but will be fixed by holder object, can cause the inconvenient problem of taking.

Summary of the invention

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail.

Embodiment 1, as Figure 1-3, a kind of built-up pallet external member, comprise by holder object 2 and tray body 1, described tray body 1 is embedded with some electromagnet 11, described electromagnet 11 couples and is controlled by a human body touch switch 12, described human body touch switch 12 is arranged at tray body 1 bottom, described tray body 1 is also provided with battery pack, described human body touch switch 12 comprises switch element, described switch element is coupled between described battery pack and described electromagnet 11, in the time of human body contact human body touch switch 12, described switch element conducting is so that electromagnet 11 obtains electric to being produced suction by holder object, in the time that human body leaves contact-making switch, described switch element ends to make electromagnet 11 dead electricity, pallet can be circular.

In the time that needs are lifted by holder object 2 by pallet, from however speech, all need directly to lift tray bottom by hand, now, only a finger directly need to be contacted with human body touch switch 12, just can complete make electromagnet 11 electric, when above-mentioned pallet self can coordinate other to be ask object 2 to use, tray body 1 just can the use of built-up pallet external member.

Embodiment 2, on the basis of embodiment 1, to be ferrous material by holder object 2, by some comparatively common ferrous materials, be for example applied in medical applications, medicine equipment is ferrous material, the magnetic force so now directly producing on pallet just can be fixed these ferrous materials, in the time that pallet is normally placed, these irony medicine equipments are conveniently taken, and do not have fixing inconvenient situation.

Embodiment 3, as shown in Figure 3, on the basis of embodiment 1, the described bottom by holder object 2 is provided with magnetite. By such setting, for example, at catering industry, because tableware is not set to irony in Yidu City, so can embed a magnet in the bottom of tableware, can play equally this effect.

Embodiment 4, on the basis of embodiment 1, as shown in Figure 4, the top of described electromagnet 11 is provided with electro-insulating rubber layer 14. Described electro-insulating rubber layer 14 forms a plane with described tray upper surface.

Embodiment 5, on the basis of embodiment 4, protrudes from tray body 1 upper surface by described electro-insulating rubber layer 14, plays spacing effect, and electro-insulating rubber layer 14 is answered interference fit in tray body 1 upper surface, prevents that liquid inflow from making internal short-circuit.

Embodiment 6 is with reference to shown in Fig. 2, and described battery pack is some button cell compositions. Described tray body 1 offers battery case 13, and described battery pack is arranged at battery case 13 inside. Consider design cost, select button cell, can select in principle the battery that any thickness is less.

Embodiment 7 is with reference to shown in Fig. 5, and the bottom of described tray body 1 is provided with groove, and described human body touch switch 12 is arranged at inside grooves. The contact end face of described human body touch switch 12 is set to cambered surface 301, and the protrusion direction of described cambered surface 301 upwards arranges.

Embodiment 8 is with reference to shown in Fig. 5, on the basis of embodiment 1, human body touch switch 12 comprises amplifying circuit 30, rising edge circuits for triggering 31 and trailing edge circuits for triggering, the output of described amplifying circuit 30 couples respectively rising edge circuits for triggering 31 and trailing edge circuits for triggering, in the time that rising edge circuits for triggering 31 capture the rising edge that amplifying circuit 30 exports, output switching element conducting, in the time that trailing edge circuits for triggering capture the trailing edge that amplifying circuit 30 exports, the cut-off of gauge tap unit. as shown in Figure 6, its principle is to utilize two d type flip flops, in the time of human body touch, what produce is rising edge, and by the design of rising edge circuits for triggering 31U2, in the time producing rising edge, clock end to U2 is inputted, so now can trigger D signal one time, produce high level, and now, same rising edge is held to CP, can not trigger, because the CP pin of U1 has phase inverter, so can not trigger, and because the output of U1 exists phase inverter, so can make to be high level with two inputs of door U3, so now be output as height, just make D1 conducting, electromagnet 11 obtains electric work, in the time that trailing edge circuits for triggering capture trailing edge, due to the time delay of phase inverter, now U2 can not trigger, but the CP pin of U1 triggers, now, if the D pin of U1 does not connect phase inverter, the signal of D pin is ahead of the signal (being low level) of CP, cause exporting, and D pin has connect two phase inverters, make its signal lag in CP signal (time delay of phase inverter technique), so when contact trailing edge, trigger U1 high level output, make to have low level input with door U3, be output as low, cut-off D1, make electromagnet 11 dead electricity, in sum, foregoing circuit is realized, contact electricly, depart from the function of dead electricity, and D11, D12, D13 and D14 all play the function that prevents that electric current reverse direction flow from crossing, and U1 and U2 realize signal interlocking by output phase mutual connection reset terminal.

Embodiment 9, with reference to shown in Fig. 7, realizes two d type flip flops with flip and flop generator, when upper human body Contact produces rising edge, CP end directly catches, make its output high level, control and realize output, and human body leaves while producing trailing edge, directly trigger the not gate output of holding by CP, and unnecessary energy consumption consumes on R1, now because triggering, R end exists in advance, so it is low to ensure that it is output as, control it and be output as low level, realize the cut-off control to D1. This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art are reading after this description and can make to the present embodiment the amendment that there is no creative contribution as required, but as long as within the scope of claim of the present invention, are all subject to the protection of Patent Law.
