Alternatively, described lead sealing cover plate and described upper shell are pasted together, and cover described countersunk head screw and described upper shell, form the paper lead sealing.
Alternatively, the edge of described upper shell is provided with rhone.
Alternatively, described lead sealing cover plate is sheet metal component.
Alternatively, to pass the hole of described lead sealing cover plate be turbination to described countersunk head screw.
Alternatively, described upper shell is die casting.
Alternatively, have the square opening that appears the verification switch below the switch lock symbol of described upper shell, described verification switch left and right can be stirred.
Compared with prior art, the utlity model has following advantage:
The utility model not only can easily be realized the waterproof requirement of electronic balance IP65 grade, and have easy and simple to handle, the characteristics of compact conformation.
In addition, the utility model is reasonable in design, and novelty simple for structure has been saved material cost greatly, and safe and reliable, has applicability widely.

Embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can be in the situation that do similar popularization, deduction without prejudice to the utility model intension according to practical situations, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
Fig. 1 is the schematic appearance of the lead sealing mechanism of an embodiment of the utility model; Fig. 2 is the blast structural representation of the lead sealing mechanism of an embodiment of the utility model.It should be noted that this and follow-up other accompanying drawing all only as example, it is not to be to draw according to the condition of equal proportion, and should not be construed as limiting as the protection domain to the utility model actual requirement with this.
Please main reference shown in Figure 2, the lead sealing mechanism of this waterproof mainly comprises lead sealing screw 1, countersunk head screw 2, lead sealing cover plate 3, waterproof foam 4, Quincunx screw 5 and lead sealing switch 7.Wherein, Quincunx screw 5 gets up upper shell 6 and lower house 8 interlockings of electronic balance, waterproof foam 4 is pasted on the lower surface of lead sealing cover plate 3, and then lead sealing cover plate 3 is placed on the square groove interior (Fig. 4) of upper shell 6, and by lead sealing screw 1 and countersunk head screw 2 fixed locks.
In the present embodiment, there is a circular hole (Fig. 3) at the flange center of lead sealing cover plate 3, and a hole (not shown) is also arranged on lead sealing screw 1, and a filament passes respectively this two hole, just can form the line lead sealing.Lead sealing cover plate 3 and upper shell 6 are pasted together, and directly cover countersunk head screw 2 and upper shell 6, just can form the paper lead sealing.When using, only have line lead sealing or paper lead sealing are destroyed after, lead sealing cover plate 3 is opened, just can by the square hole toggle switch on upper shell 6, carry out the operation that verification arranges.In addition, the edge of upper shell 6 is provided with rhone, can not occur ponding on every side in lead sealing mechanism.
Fig. 3-1 is the vertical view of the lead sealing cover plate of an embodiment of the utility model; Fig. 3-2 are the plan view (facing down) of the lead sealing cover plate of Fig. 3-1 illustrated embodiment.Please in conjunction with shown in Fig. 3-1 and Fig. 3-2, this lead sealing cover plate 3 can be sheet metal component, and structural safety is reliable.The hole that this countersunk head screw 2 passes lead sealing cover plate 3 is turbination, and purpose is to make countersunk head screw 2 not higher than lead sealing cover plate 3, the paper lead sealing is pasted more firm.Turning over paracentral small sircle hole uses for aforementioned line lead sealing threading.
