Description

The waterproof electronic scales

The utility model belongs to weighing equipment, particularly a kind of waterproof electronic scales.

Generally,, weigh with traditional mechanical lever-type grounding platform balance usually as fish food market etc. in moist place.This mechanical lever-type grounding platform balance comprises scale base, the arm beam of steelyard and the sliding weight of steelyard of being made by metal material, so it has not water funk function of drenching.Yet this mechanical lever-type platform balance is to estimate with leverage, not only must be held by the special messenger and make the increase and decrease counterweight, and mostly judge with similar value or by empirical value, and its value is comparatively inaccurate.For this reason, manufactured and designed electronic scales miscellaneous according to different purposes.Existing electronic scales system mostly comprises the housing that is made of loam cake that engages and lower cover and places circuit and electronic component in the housing.Has waterproof construction yet the joint of the electronic scales upper and lower cover of commonly using is neither, so when electronic scales places outdoor or the high humidity place, as reefer or fish market, when cleaning ground as rainy or water, often cause water to infilter this electronic scales inside, thereby cause the short circuit and the electronic component oxidation fault of internal circuit from the joint of housing upper and lower cover.

The purpose of this utility model provides a kind of anti-sealing and infiltrates inner, as to guarantee normal use waterproof electronic scales.

The utility model comprises weight display unit, electronic scales body, signal bar collision mat frame and waterproof washer; The weight display unit comprises panel, display screen, frame lid, deckle board and the circuit board that is combined into one in regular turn; The electronic scales body comprises skeleton frame, be locked in the lower fixed frame of skeleton frame lower end and be located at the component groups of skeleton frame inside; Skeleton frame is that front end is the inclined-plane shedding shell, and ring is established groove on every side along the inclined-plane, and the bottom of skeleton frame is provided with hole; The frame lid of collision mat frame and weight display unit and the skeleton frame of electronic scales body are corresponding; The collision mat frame is placed in the groove, and by the sealed compression fit of frame lid with skeleton frame; The signal bar passes hole and is communicated with skeleton frame internals group, and waterproof washer is placed between signal bar and the skeleton frame hole.

Wherein:

Electronic scales body lower end is provided with support pipe support that is connected to lower fixed frame and the scale base that is connected with support pipe support lower end.

Component groups comprises battery, load cell and is locked in base of frame inner face upper holder.

Because the utility model comprises weight display unit, electronic scales body, signal bar, collision mat frame and waterproof washer; The electronic scales body comprises skeleton frame, lower fixed frame and component groups; Skeleton frame is that front end is the inclined-plane shedding shell, and ring is established groove on every side along the inclined-plane, and the bottom of skeleton frame is provided with hole; The collision mat frame is placed in the groove, and by the sealed compression fit of frame lid with skeleton frame; The signal bar passes hole and is communicated with skeleton frame internals group, and waterproof washer is placed between signal bar and the skeleton frame hole.By collision mat frame and waterproof washer the joint of electronic scales housing upper and lower cover is closely sealed, infiltrated electronic scales inside to avoid water, reach water-proof function, anti-sealing infiltrates inside, guarantees normal use, thereby reaches the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises weight display unit 1, electronic scales body 2, signal bar 3, collision mat frame 24 and waterproof washer 25.

Weight display unit 1 comprises panel 10, display screen 11, frame lid 12, deckle board 13 and the circuit board that is combined into one in regular turn.

Electronic scales body 2 comprises skeleton frame 20, be locked in the lower fixed frame 26 of skeleton frame 20 lower ends and be located at the component groups of skeleton frame 20 inside.Component groups comprises battery 21, load cell 22 and is locked in framework 20 bottom inner face upper holders 23.

Skeleton frame 20 is the inclined-plane shedding shell for front end, and ring is established groove 200 on every side along the inclined-plane.The bottom of skeleton frame 20 is provided with hole 201.Signal bar 3 passes hole 201 and is communicated with skeleton frame 20 internals groups.Signal bar 3 upper ends are provided with by the hole 201 of lower fixed frame 26, skeleton frame 20 and upper holder 23 and are locked in bolt 30 on the load cell 22.

The frame lid 12 of collision mat frame 24 and weight display unit 1 and the skeleton frame 20 of electronic scales body 2 are corresponding.

As shown in Figure 4, collision mat frame 24 is placed on skeleton frame 20 and is in the groove 200 of diagonal cut joint, and by the sealed compression fit of frame lid 12 with skeleton frame 20, to have sealed waterproof effect

As shown in Figure 5, waterproof washer 25 is placed in the gap between bolt 30 and the hole 201, and is fit to bolt 30 and lower fixed frame 26, the hole 201 of skeleton frame 20 and the joint of upper holder 23, makes it have the effect of water-tight.

As shown in Figure 6, also can be connected with support pipe support 4 and scale base 5 in electronic scales body 2 lower ends.Supporting pipe support 4 be hollow tube, and its upper end merges with signal bar 3 covers and is locked on electronic scales body 2 lower fixed frames 26, and signal bar 3 lower ends in support pipe support 4 are provided with the hook 31 that is connected with cable 40, and the other end of cable 40 is connected to scale base 5 inside.

Scale base 5 is to supply any large object weighing usefulness, and electronic scales body 2 is because of having water-proof function, thus can place any moist local, as the fish food market etc.

In sum, the utility model closely seals the joint of electronic scales housing upper and lower cover by collision mat frame and waterproof washer, infiltrates electronic scales inside to avoid water, reaches water-proof function.
