It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all belong to the protection scope of the present utility model.

[0039] As Figures 1-5 shown, a portable weighing indicator housing provided according to the present utility model includes: a front shell 2, a rear shell 3, and a movable bracket 5. The front shell 2 is fixedly connected to the front of the rear shell 3. A first-layer cavity 31 is formed on the back of the rear shell 3 at the upper part and a second-layer cavity is formed at the lower part. The first-layer cavity 31 is used to place a weighing indicator interface or a wireless receiving antenna; at the top of the left and right sides of the movable bracket 5, shafts 54 are symmetrically arranged. The movable bracket 5 is movably installed in the second-layer cavity through the shafts 54 on both sides, and the movable bracket 5 can rotate around the shafts 54; the second-layer cavity includes a first-layer cavity of the second-layer cavity 321, a middle-layer cavity of the second-layer cavity 322, and a lower-layer cavity of the second-layer cavity 323. A support wall A33 is arranged between the first-layer cavity 31 and the second-layer cavity. A support wall B34 is arranged between the middle-layer cavity 322 and the lower-layer cavity 323 of the second-layer cavity; the movable bracket 5 includes a retracted state and a supported state. When the movable bracket 5 is in the retracted state, the movable bracket 5 is fixedly connected to the rear shell 3 through the arc-shaped bosses 55 at the bottoms of the left and right sides; when the movable bracket 5 is in the supported state, the movable bracket 5 is installed in the second-layer cavity. The movable bracket 5 is fixedly connected to the rear shell 3 through the hooks B53 at the top. An included angle is formed between the movable bracket 5 and the rear shell 3, and the movable bracket 5 is respectively in contact with the support wall A33 and the support wall B34.

[0040] A microprinter cover plate 1 is installed on the front of the front shell 2, and a calibration cover plate 4 is installed on the back of the rear shell 3.

[0041] The first-layer cavity 31 is used to place various interfaces of the weighing indicator and place fingers when carrying with one hand, or hide the wireless receiving antenna of the weighing indicator. A side wall A311 is arranged at the top of the first-layer cavity 31. When carrying, the side wall A311 serves as a handle. Two grooves A3111 for placing the antenna are symmetrically arranged on the side wall A311, that is, for avoiding space when the wireless receiving antenna faces upward.

[0042] The second cavity is used to assemble the movable bracket 5 and accommodate two assembly states of the movable bracket 5, namely the retracted state and the supported state of the movable bracket 5. The second cavity is mainly composed of upper, middle and lower three-layer spaces, and its left and right spaces are symmetrical.

[0043] The movable bracket 5 is symmetrical in shape about the left and right. Two hooks B53 are symmetrically arranged at the top of the movable bracket 5, and two hooks A3231 are correspondingly arranged on the lower layer 323 of the second cavity. The movable bracket 5 and the rear shell 3 are tightly connected by snap-fitting of the hook A3231 and the hook B53.

[0044] Side walls B324 are respectively arranged on both sides of the second cavity. A groove B3241 corresponding to the shaft 54 is arranged on the side wall B324, and the shaft 54 is movably installed in the groove B3241.

[0045] A groove C3242 corresponding to the arc-shaped boss 55 is arranged on the side wall B324. The movable bracket 5 and the rear shell 3 are tightly connected by snap-fitting of the arc-shaped boss 55 and the groove C3242.

[0046] Grooves F52 for placing the receiving antenna in the retracted state are symmetrically arranged on the left and right sides of the movable bracket 5. One function is to place the receiving antenna in the retracted state, and the other function is to place fingers when the weighing indicator is held by hand, making the grip more comfortable and stable. A groove E3221 corresponding to the groove F52 is arranged at the bottom of the middle layer 322 of the second cavity, and the groove F52 is arranged in the groove E3221, that is, the groove E3221 is used to avoid the groove F52 of the movable bracket 5.

[0047] A concave platform 3211 for pasting the product nameplate is arranged at the bottom of the upper layer 321 of the second cavity. A rectangular hole 51 is arranged in the middle of the movable bracket 5, and the rectangular hole 51 is arranged outside the concave platform 3211, and the rectangular hole 51 does not cover the concave platform 3211, aiming to expose the pasted product nameplate.

[0048] A groove D35 is arranged in the middle of the connection between the lower part of the second cavity and the bottom surface of the rear shell 3. The movable bracket 5 does not completely cover the groove D35, and the groove D35 is used to insert fingers to apply force when the movable bracket 5 is opened.

[0049] The four corners of the front shell 2 are wrapped with soft rubber protection parts 21. The four corners of the front shell 2 are wrapped with soft rubber, which plays a buffering and protecting role when the product accidentally drops.

[0050] The assembly of the movable bracket 5 is mainly carried out by using the elastic deformation of the plastic. The shafts 54 on the left and right sides are respectively placed into the grooves B3241 of the second cavity of the rear shell 3, and then the movable bracket 5 is rotated so that the arc-shaped bosses 55 on its left and right sides are snapped into the grooves C3242 of the rear shell 3. At this time, the movable bracket 5 is in the retracted state.

[0051] Insert a finger into the groove D35 provided on the rear shell 3, and pull up the movable bracket 5 to make it rotate. When the movable bracket 5 rotates 90 degrees and is perpendicular to the rear shell 3, press down the movable bracket 5 to the bottom of the lower layer 323 of the second cavity of the rear shell 3. At this time, the hook A3231 provided in the second cavity will hook the hook B53 provided on the movable bracket 5. This is the supporting state of the movable bracket 5. At this time, the supporting wall A33 and the supporting wall B34 of the rear shell 3 will contact the movable bracket 5, and the stress points are at positions A and B shown in the figure. In this way, the shaft 54 of the movable support will not be stressed, that is, it is not easily damaged.

[0052] In this application, by placing various interfaces of the weighing indicator in the first cavity 31 and placing a finger when carrying it with one hand, or hiding the wireless receiving antenna of the weighing indicator, the effects of being portable, convenient to hold, and easy to store the receiving antenna can be achieved. By assembling the movable bracket 5 in the second cavity and adapting to the two assembly states of the movable bracket 5, the movable bracket 5 is fixedly connected in the retracted state through the arc-shaped bosses 55 at the bottoms of the left and right sides and is firmly supported in the supporting state through the hook B53 at the top and is fixedly connected to the rear shell 3. Moreover, by the movable bracket 5 contacting the supporting wall A33 and the supporting wall B34 respectively, the stress on the shaft 54 can be transferred, thereby extending the service life of the shaft 54 and effectively solving the drawback that the shaft 54 of the movable bracket 5 is easily damaged.

[0053] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0054] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Without conflict, the embodiments of this application and the features in the embodiments can be combined with each other arbitrarily.
