Description
Technical field
The utility model relates to a kind of syndeton of digital terminal box, belongs to the weighting display instrument technical field.
Background technology
Electronic scale is to receive load by LOAD CELLS, by the elastomer stress deformation, make the also distortion simultaneously of resistance strain gage that sticks on the elastomer, cause the variation of resistance strain gage resistance, by measuring circuit weight signal is transformed into the corresponding signal of telecommunication and exports to the data-signal processing unit, the data-signal processing unit is handled data, by Displaying Meter the weight of measuring is shown at last, and data output is printed or uploads by the PORT COM on the weighting display instrument.And in industries such as cement, metallurgy, chemical industry, grain processing, petrochemical industry, usually with the mode of weighing material is measured or material level when controlling, a plurality of LOAD CELLS are installed in batch can or packing container bottom, the weight or the material level of material in the automatic gauge batch can, the weight signal that detects in LOAD CELLS inserts digital terminal box and gathers, and reaches Displaying Meter.Because digital terminal box often is to place outdoor use,, therefore degree of protection there is very high requirement because rainwater, dust, steam and pernicious gas etc. all can have influence on the service behaviour and the useful life of digital terminal box.In the O﹠M process, need often open the lid inspection of terminal box, as checking the smooth and easy of network communication, to guarantee operate as normal.Present terminal box is to be provided with the V-arrangement shell fragment around the housing outer wall, and sealing ring is enclosed within the open top of housing, and the active edges of V-arrangement shell fragment is arranged on the step surface place of lid inwall, and lid is by sealing ring and housing seal, and the aperture on the lid is relative with the V-arrangement shell fragment.Therefore all need be for the reed-type hermetically-sealed construction by slot type screwdriver in opening and closing, make the V-arrangement shell fragment reliably be installed in the step surface place of lid inwall, or the active edges of the V-arrangement shell fragment of depressing by the aperture on the lid, and opening and closing lid, operation is comparatively inconvenient.Owing to only be stuck in the step surface place of lid by the active edges of V-arrangement shell fragment, after lid was opening and using several times, the V-arrangement shell fragment was damaged by flat blade screwdriver easily on the other hand, caused barrier propterty to descend.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and easy accessibility has the syndeton of the digital terminal box of better barrier propterty.
The utility model is that the technical scheme that achieves the above object is: a kind of syndeton of digital terminal box, comprise housing, sealing ring and lid, its outer wall rear side of housing that described top has opening is provided with plural V-arrangement shell fragment, the active edges of V-arrangement shell fragment withstands on the step surface place of lid inwall, and the aperture on the lid is relative with the V-arrangement shell fragment, sealing ring is installed in the open top of housing and is tightly connected with lid, it is characterized in that: the front side of described housing outer wall is provided with at least two U-shaped fixed supports, biside plate on the U-shaped fixed support is provided with slotted eye and following slotted eye, both ends of the spring is separately positioned in slotted eye and the following slotted eye and can moves up and down, the hasp lower end is connected with spring, and rising to the bait of hasp top is relative with fore shaft on the lid.
The utility model is provided with plural V-arrangement shell fragment at housing outer wall rear side, and the front side of housing outer wall is provided with at least two U-shaped fixed supports, both ends of the spring is separately positioned on the biside plate on the U-shaped fixed support, the hasp lower end is connected with spring, the hasp upper end is provided with rises to the bait, by the operation hasp it is moved up and down, be hooked in rising to the bait in the fore shaft of lid, or move from fore shaft, and lid can rotate as fulcrum by the V-arrangement shell fragment, the U-shaped fixed support of housing outer wall front side and the V-arrangement shell fragment of rear side are merged, simple in structure, because hasp moves up and down by spring and resilient force under, make hasp up and down and move forward and backward, and need be by other instruments, can be easy to open and close lid, easy to operate.In addition, the utility model is hooked in respectively on lid and the spring owing to hasp, lid reliably is connected with housing, and increased the power that is connected between lid and the housing, keep sealing ring can closely be pressed in the port of housing, thus when often with lid when housing opens and closes, can not cause any infringement to hermetically-sealed construction yet, degree of protection improves greatly, and degree of protection can reach IP66, the requirement of IP68 and IP69K.
