[0068] The plastic middle frame 20 comprises a frame body 201, and the frame body 201 is internally provided with a fixing member 202 integrally formed with the frame body 201 for fixing the weighing and display device; the metal upper shell 10 is provided with a window opening 101 at the upper end surface for exposing the functional structural members of the weighing and display device, and the metal upper shell 10 is fixedly stacked on the upper portion of the frame body 201, and the metal bottom shell 30 is fixedly stacked on the lower portion of the frame body 201.

[0069] Based on the above, it can be clear that the application is mainly used as a weighing instrument 1000 with an embedded plastic middle frame in specific implementation.

[0070] Specifically, in the application of the present application, the plastic middle frame 20 is provided with a fixing member 202 integrally formed with it for fixing the weighing digital display device. Obviously, since the plastic middle frame 20 is made of plastic material, the material determines that the fixing member 202 is integrally formed with it by injection molding, which makes the overall structure of the fixing member 202 stable and not easy to loosen and displace, so that the weighing digital display device is conveniently and stably fixed and installed, thereby improving the reliability of the application.

[0071] At the same time, the metal upper shell 10 is laminated and fixed on the upper part of the frame body 201, and the metal bottom shell 30 is laminated and fixed on the lower part of the frame body 201, so that the outer shell body part of the weighing instrument 1000 with an embedded plastic middle frame is basically made of metal material, which is hard and firm in texture, has good anti-impact effect, is not easy to be broken by impact, has long service life, and the plastic middle frame 20 and the fixing member 202 are made of plastic material, which can reduce the amount of metal shell, thereby reducing the overall cost of the application.

[0072] Furthermore, the above optimization design makes the overall application have high practicability and good use effect.

[0073] Further, in specific implementation, according to an embodiment of the present application, a limiting ring 2011 is annularly arranged outwardly on the middle part of the outer wall of the frame body 201;

[0075] Therefore, by arranging the limiting ring 2011, the metal upper shell 10 and the metal bottom shell 30 are conveniently limited and fixed in position, and the lower part of the metal upper shell 10 is overmolded on the upper part of the frame body 201, and the lower periphery thereof is tightly fitted with the upper periphery of the limiting ring 2011; the upper part of the metal bottom shell 30 is overmolded on the lower part of the frame body 201, and the upper periphery thereof is tightly fitted with the lower periphery of the limiting ring 2011, so that the lower periphery of the metal upper shell 10 and the upper periphery of the metal bottom shell 30 are not easy to be impacted and inwardly concave, thereby prolonging the service life of the application.

[0076] Meanwhile, the limiting ring 2011 is exposed, so that the metal upper shell 10 and the metal bottom shell 30 present a three-layer structure, so that the weighing instrument 1000 with the embedded plastic middle frame is more three-dimensional and has a level, so that it is more beautiful and atmospheric.

[0081] Therefore, by arranging the lower bottom plate 203, the overall structure of the frame body 201 is more stable and is not easily deformed by impact, and when the fixing part 202 is arranged on the upper end surface of the lower bottom plate 203, the fixing part 202 is easily integrally injection molded with the lower bottom plate 203 and the frame body 201 and facilitates the overall demolding.

[0082] Meanwhile, the metal bottom shell 30 is tightly attached to the lower periphery of the limiting ring 2011, and when the inner bottom surface of the metal bottom shell 30 is tightly attached to the lower bottom surface of the lower bottom plate 203, the metal bottom shell 30 can be more stably fixed, and in the implementation, strong adhesive can be added between the inner bottom surface of the metal bottom shell 30 and the lower bottom surface of the lower bottom plate 203 to connect them to form an integral whole.

[0085] For the above-mentioned weighing display screen, power key, function switch key, cumulative weighing key, skin key and weighing reset key and other functional structural parts, they are various functional structural parts commonly seen on existing weighing instruments, and the present application also has the same, and also has a plurality of the above-mentioned functional structural parts, and the viewing window 101 corresponds to at least include the weighing display screen exposure port 1011, the power key exposure port 1012, the function switch key exposure port 1013, the cumulative weighing key exposure port 1014, the skin key exposure port 1015 and the weighing reset key exposure port 1016, so that the weighing display screen, power key, function switch key, cumulative weighing key, skin key and the weighing reset key and other functional structural parts are exposed and used.

[0086] Again, in specific implementation, according to an embodiment of the present application, a plurality of hollow studs 2031 are uniformly and upwardly protruded on the upper end surface of the lower bottom plate 203 near the periphery thereof;

[0087] Among them, a plurality of fixing holes A102 are uniformly and downwardly arranged on the upper end surface of the metal upper shell 10 near the periphery thereof, and a plurality of the fixing holes A102 correspond to the hollow studs 2031 located directly above; the metal upper shell 10 is connected with the lower bottom plate 203 to form an integral body by rotating the fixing bolts A40 from top to bottom into a plurality of groups of fixing holes A102 and hollow studs 2031 located directly above.

[0088] Therefore, through the optimization design of the above structure, the metal upper shell 10 and the lower bottom plate 203 can be connected to form an integral body.

[0089] On this basis, according to an embodiment of the present application, the present application further comprises a protective film 50;

[0090] Among them, the protective film 50 is attached to the upper end surface of the metal upper shell 10 to seal and cover the viewing window 101 and a plurality of the fixing holes A102.

[0091] Therefore, by setting the protective film 50, the viewing window 101 and a plurality of the fixing holes A102 can be better sealed and covered, so that the present application has good waterproof and dustproof effect, and external water stains and dust are not easy to enter the inside of the present application through the metal upper shell 10.
