Fig. 2 is a schematic structural view of a paper lead seal in the multi-scale lead seal structure of the present invention. Fig. 3 is a schematic structural view of a centerline lead seal of the multi-scale lead seal structure of the present invention.
As shown in fig. 1 to 3, the present invention discloses a multi-scale lead sealing structure, which comprises a housing 10, a plurality of scale circuit board assemblies 20, a plurality of lead sealing covers 30 and a plurality of lead sealing screws 40. Wherein, the scale platform circuit board assembly 20 is disposed in the housing 10, each lead sealing cover 30 covers the corresponding scale platform circuit board assembly 20, the lead sealing screw 40 is inserted into the corresponding scale platform circuit board assembly 20 and the lead sealing cover 30 from the bottom of the housing 10, and the portion of the lead sealing screw 40 located at the bottom of the housing 10 is lead sealed by using a lead sealing component.
Preferably, each lead enclosure 30 is secured to the housing 10 by a plurality of screws 31. The scale circuit board assembly 20 includes a scale circuit board, an electronic component, a scale harness, and a connector, which are connected to each other.
Further, a seal ring 50 is provided between the lead seal screw 40 and the housing 10.
The shell 10 is provided with a first threaded hole 11, the lead sealing cover 30 is provided with a second threaded hole 32, and a lead sealing screw 40 sequentially passes through the first threaded hole 11 and the second threaded hole 32 and is screwed and fixed in the second threaded hole 32.
The lead sealing part of the lead sealing screw 40, which is located at the bottom of the housing 10, is lead sealed by a paper lead sealing member. For example, the lead sealing component of the paper lead sealing is a lead sealing paper 41, and the lead sealing paper 41 is attached to the bottom of the housing 10 to cover the exposed part of the lead sealing screw 40.
In addition, the portion of the lead sealing screw 40 located at the bottom of the housing 10 can be lead sealed by using a lead sealing component of a wire lead seal. For example, the lead sealing component of the wire lead sealing comprises a lead sealing wire 42, a lead sealing head 43 and a lead sealing column 44, the lead sealing column 44 is fixed at the bottom of the shell 10, and the lead sealing wire 42 passes through the lead sealing screw 40 and the lead sealing column 44 in sequence, is tensioned and is connected into the lead sealing head 43.
The utility model also provides a weighing instrument which comprises the multi-weighing platform lead sealing structure.
According to the structural description, for installing a plurality of independent weighing platform circuit board assemblies in the instrument, the multi-weighing platform lead sealing structure can realize that each weighing platform circuit board assembly is separately lead-sealed with the shell, so that the maintenance of other parts in the instrument is not influenced, or only the weighing platform circuit board needing to be maintained is subjected to lead sealing breaking maintenance, and the lead sealing states of other weighing platform circuit boards are not influenced.
The lead sealing mode for each weighing platform is as follows: the electronic components related to the measurement of the platform board assembly 20, the platform harness and the connector 21 are covered by the lead cover 30, and the platform board assembly 20 is fixed to the housing 10 by the screws 31. The lead seal screw 40 passes through the seal ring 50 and the platform circuit board assembly 20 from the threads of the housing 10 and screws into the threads of the lead seal cover 30. Then, the lead sealing and paper lead sealing modes are different according to different countries and regional lines, and the modes are slightly different.
Aiming at the paper lead sealing mode, the fragile lead sealing paper 41 is used and is pasted on the round hole of the shell 10 to cover the lead sealing screw 40, so that the lead sealing screw 40 cannot be detached under the condition that the fragile lead sealing paper 41 is not damaged, and then the weighing platform circuit board assembly 20 or the weighing platform wiring harness and the joint 21 and other parts influencing the metering performance are replaced.
Aiming at the line lead sealing mode, a lead sealing wire 42 and a lead sealing head 43 (not limited to a plastic lead sealing head and a metal lead sealing head) are used, the lead sealing wire 42 sequentially penetrates through a round hole 45 of a lead sealing screw 40 and a round hole of a lead sealing column 43, is tensioned and converged into two holes of the lead sealing head 43, and is buckled with the plastic lead sealing head or is compacted with a lead sealing clamp, so that the installation of the line lead sealing is completed.
If there are multiple weighing platform circuit boards, the lead sealing mode of other weighing platforms is the same, and the description is omitted here. In this embodiment, the technical solution of the present application is described with only two weighing platforms, but the usage scenario of the technical solution of the present application is not limited by the number of the weighing platform circuit board assemblies, and is within the protection scope of the present application.
For example, for a customer who purchases a multi-scale weighing meter, assuming 2 scales, after lead sealing, two years of use, the power module is damaged by accident and needs to be replaced. Because the power module is not sealed by lead, the instrument shell can be directly opened without breaking the lead seal, and the new power module can be replaced. If the second scale circuit board is damaged, it needs to be replaced. In this case, only the lead seal of the second scale platform can be broken, and the lead seal of the first scale platform can not be broken when the second scale platform is replaced or maintained.
The multi-weighing platform lead sealing structure and the weighing instrument comprising the same strip components related to metering from other parts, and carry out local lead sealing independently instead of integral lead sealing of a shell. Meanwhile, a plurality of weighing platforms (which can be the same weighing platform or different weighing platforms) can be repeatedly sealed by lead independently.
In summary, the multi-weighing platform lead sealing structure and the weighing instrument comprising the same have the following advantages:
the scheme of independent lead sealing with multiple weighing platforms is adopted, so that other parts irrelevant to metering performance, such as a power supply module, a display module and other communication modules, can be maintained under the condition of not damaging the lead sealing, such as PLC communication, serial port communication and the like, and the maintenance is more convenient and economical.
And secondly, a photoelectric switch is added on the weighing platform circuit board, and after the lead sealing screw is installed, software can identify the lead sealing state of each weighing platform and display the lead sealing state of each weighing platform on an instrument software interface.
