The weighing sensor 22 is used to sense the weight of the object being carried, so as to determine the weight of the object. The upper weighing body 20 carries the object via an outer cover 23. The sensor 22 deforms under the force of gravity and outputs a corresponding electrical signal.
[0043] The instrument 30 is installed on the lower weighing body 10 and located on the rear side of the upper weighing body 20. The instrument 30 and the upper weighing body 20 are arranged at intervals so that the instrument 30 and the upper weighing body 20 can be arranged independently, thus avoiding mutual interference between the instrument 30 and the upper weighing body 20.
[0044] Please refer to the attached document. Figures 1-5 In this embodiment, the handle hole 10a is located near the front sidewall of the lower scale body 10 and is arranged along the length of the front sidewall of the lower scale body 10. The handle hole 10a is an elongated hole structure, which can reduce the overall weight of the lower scale body 10 and also form a partial hollow space. The inner sidewall of the handle hole 10a and the front sidewall of the lower scale body 10 form a lifting portion 12, which can be lifted by the user's fingers, allowing the user to lift the lower scale body 10 with one hand. The user can easily carry the portable platform scale 100 with one hand by lifting it.
[0045] Please refer to the attached document. Figures 1-5 In this embodiment of the application, among the four support screws 11, two support screws 11 are distributed on both sides of the handle hole 10a and close to the front side wall of the lower scale body 10, which ensures the levelness of the front side wall of the lower scale body 10.
[0046] Please refer to the attached document. Figures 1-5 In this embodiment, four support screws 11 are provided, distributed at the corners of the lower scale body 10. The four support screws 11 are screwed from bottom to top to the bottom of the lower scale body 10; the ends of the four support screws 11 are located on the lower side of the bottom of the lower scale body 10 and can contact the working platform. By arranging four support screws 11, the stability of the lower scale body 10 relative to the working platform is increased, preventing the upper scale body 20 from tilting relative to the working platform and improving the measurement accuracy of the upper scale body 20.
[0047] Please refer to the attached document. Figures 1-5 Please refer to the appendix. Figures 1-5In this embodiment, the ends of the support screws 11 are adjusted in position relative to the bottom of the lower scale body 10 by manual rotation of the support screws 11; the adjustment of the positions of the ends of the four support screws 11 regulates the levelness of the lower scale body 10, so that the lower scale body 10 can be adjusted in levelness by manual action, avoiding the lower scale body 10 from swaying relative to the work platform. Optionally, the four support screws 11 are arranged diagonally.
[0048] The end of the support screw 11 is provided with an adjustment groove. Optionally, the adjustment groove is configured as a cross groove or a hexagonal countersunk hole to facilitate tool-driven screw adjustment. Preferably, the support screw 11 and the lower scale body 10 are screw-fitted together.
[0049] Please refer to the attached document. Figures 1-5 In this embodiment, the first stud 21 is arranged vertically and installed on the lower scale body 10. The free end of the first stud 21 protrudes towards the upper scale body 20, and a limiting space is formed between the end and the upper scale body 20. The upper scale body 20 weighs the external object under the action of the load cell 22 to understand the weight of the external object, so that the lower scale body 10 can support the upper scale body 20 through the first stud 21, thereby avoiding overload damage to the sensor 22 by the upper scale body 20.
[0050] The first stud 21 can move up and down along the lower scale body 10 to facilitate contact with the upper scale body 20 during transportation and provide protection for the sensor 22. The surface of the lower scale body 10 and the lower surface of the upper scale body 20 are spaced apart by the first stud 21, and the space formed allows the user's fingers to grasp the lifting part 12, avoiding the upper scale body 20 restricting the user's fingers.
[0051] The upper scale body 20 is fitted with an outer cover 23, which protects the upper scale body 20 and prevents external objects from directly contacting it. Optionally, the outer cover 23 is made of materials such as stainless steel to improve corrosion resistance.
[0052] Please refer to the attached document. Figures 1-5 In this embodiment, the first stud 21 is connected to two first nuts 211. The two first nuts 211 jointly lock the first stud 21 at a defined position on the lower scale body 10, thereby preventing any height difference between the first stud 21 and the lower scale body 10. The first stud 21 restricts the position of the upper scale body 20 and the lower scale body 10 through the two first nuts 211, thereby facilitating the upper scale body 20 to be in a fixed state relative to the lower scale body 10.
[0053] Please refer to the attached document. Figures 1-5In this embodiment, the instrument 30 is installed on the lower scale body 10 and located on the rear side of the lower scale body 10, so that the instrument 30 can be fixed on the rear side of the lower scale body 10. The lower scale body 10 is provided with a receiving hole 10b, and part of the instrument 30 is inserted into the receiving hole 10b and located inside the receiving hole 10b, so that the instrument 30 can make full use of the space of the receiving hole 10b and avoid interference between the instrument 30 and the lower scale body 10.
[0054] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the instrument 30 is connected to the lower scale body 10 through the second stud 31 to fix the instrument 30 to the lower scale body 10. The second stud 31 is connected to the second nut 311, and the second nut 311 contacts the lower scale body 10 so that the position of the instrument 30 relative to the lower scale body 10 is restricted by the second nut 311, thus ensuring that the instrument 30 is fixed relative to the lower scale body 10.
