Abstract
A weighing instrument housing comprises a housing. The weighing instrument housing is characterized in that the housing includes a plastic housing (1), the plastic housing (1) is provided with a plastic stud (8), the plastic stud (8) is hollow and is provided with an internal thread, the housing also includes an aluminum alloy housing (2), the upper layer of the aluminum alloy housing (2) is provided with a big hole (6), the lower layer of the aluminum alloy housing (2) is provided with a small hole (7), the plastic housing (1) is pressed into the installing port of the aluminum alloy housing (2), the plastic stud (8) traverses the big hole (6) at the upper layer, a screw is reversely screwed into the plastic stud (8) of the plastic housing (1) from the small hole (7) of the aluminum alloy housing (2), and when the screw is tightly screwed, the plastic housing (1) is locked with the aluminum alloy housing (2) together. The aluminum alloy housing is combined with the plastic housing employing the plastic stud and the aluminum alloy double-layer hole structure, the structure is simple, connection is firm and stable, and the problems that no nut can be welded on aluminum alloy and the instrument housing weight is light are solved.
Description
Technical field
The utility model only relates to the shell of weighing apparatus instrument, belongs to the measurement mechanism technical field, especially for a kind of truck scale meter case.
Background technology
Truck scale is also referred to as weighbridge, it is the main weighing-appliance for the bulk supply tariff metering, generally all comprise sensor, terminal box, printer and weighing instrument, the extensive single employing metal of meter case or the plastic material of present truck scale, instrument can't have novel appearance style like this.But use two kinds of material collocation of metal and plastics, be difficult on the structure link together.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of with plastics and Al-alloy casing combine, simple and practical weighing apparatus instrument housing.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of weighing apparatus instrument housing, it includes housing, it is characterized in that: described housing comprises plastic casing, the plastics double-screw bolt is arranged on it, plastics double-screw bolt inner hollow is threaded, also comprise Al-alloy casing, its upper strata wide-bore, lower floor opens aperture, plastic casing is pressed in the installing port of aluminium alloy section shell, make the plastics double-screw bolt pass the macropore on upper strata, be screwed into to the plastics double-screw bolt to plastic casing with the aperture back of screw from Al-alloy casing again, after screw lock, be about to plastic casing and Al-alloy casing and locked together.
As improvement, the upper derby of described Al-alloy casing has threaded hole, Al-alloy casing and the support corresponding with derby also have corresponding hole, pass successively the hole of support and Al-alloy casing by screwed metal knob again and the threaded hole of derby fixes.
Compared with prior art, the utility model has the advantage of: use plastics double-screw bolt and aluminum alloy double-layer pore structure aluminium alloy gold housing and plastic casing are combined, simple in structure, be connected firmly stable, and the mode that use to increase derby solved simultaneously aluminium alloy can not welded nut and the lightweight problem of instrument housing, very practical.

Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As Figure 1-3, a kind of weighing apparatus instrument housing, it includes housing, is rectangular parallelepiped, and housing comprises plastic casing 1, and it adopts ABS plastic to make, and housing also comprises Al-alloy casing 2, it adopts aluminum alloy materials to make.Plastic casing 1 has to install 24 key holes of touch-switch, being 4 takes advantage of 6 arrays to be distributed in the lower right of housing 1, and described housing 1 is coated with the plastic foil of pattern color at key hole, and plastic foil is curved is raised in housing 1 surface, partly cooperates with the raised button of touch-switch.Plastic casing 1 adopts integrated injection molding method in the mould and connects into single piece with plastic foil.Wherein said plastic foil adopts composite membrane, and described pattern color is arranged in the interlayer of PET composite membrane.
Plastic casing 1 bottom surface arranges the plastic spiral post 8 of knowing clearly, plastics double-screw bolt 8 hollows, in be threaded structure, on the Al-alloy casing 2 at correspondence position, at upper strata wide-bore 6, open aperture 7 in lower floor, during assembling plastic casing 1 is pressed in the installing port of Al-alloy casing 2, make plastics double-screw bolt 8 pass the macropore 6 on upper strata, be screwed into to plastics double-screw bolt 8 along screw thread to the hollow space of plastics double-screw bolt 8 from the bottom up with the aperture 7 of screw from alloy housing 2 again, after plastics double-screw bolt 8 is tightened, be about to plastic casing 1 and Al-alloy casing 2 and locked together.
The upper derby 4 of Al-alloy casing 2 has threaded hole, Al-alloy casing 2 and the support 5 corresponding with derby 4 have corresponding hole, pass successively the hole of support 5 and Al-alloy casing 2 by screwed metal knob 3 again and the threaded hole of derby 4 fixes.Soon metal knob 3, derby 4, support 5 all link together, and have reached the purpose that increases weighing apparatus instrument weight by derby 4, have made it texture.
Claims (2)
1. weighing apparatus instrument housing, it includes housing, it is characterized in that: described housing comprises plastic casing (1), plastics double-screw bolt (8) is arranged on it, plastics double-screw bolt (8) inner hollow is threaded, also comprise Al-alloy casing (2), its upper strata wide-bore (6), lower floor opens aperture (7), plastic casing (1) is pressed in the installing port of aluminium alloy section shell (2), make plastics double-screw bolt (8) pass the macropore (6) on upper strata, oppositely be screwed into to the plastics double-screw bolt (8) of plastic casing (1) with the aperture (7) of screw from Al-alloy casing (2) again, after screw lock, be about to plastic casing (1) and lock together with Al-alloy casing (2).
2. weighing apparatus instrument housing according to claim 1, it is characterized in that: the upper derby (4) of described Al-alloy casing (2) has threaded hole, Al-alloy casing (2) and the support (5) corresponding with derby (4) also have corresponding hole, pass successively the hole of support (5) and Al-alloy casing (2) by screwed metal knob (3) again and the threaded hole of derby (4) fixes.
