Description

Technical Field

[0001] This utility model relates to the technical field of weighing instrument accessories, and in particular to a fixing structure adapted to different circuit boards and a weighing instrument. Background Technology

[0002] A weighing instrument is a device that uses Hooke's Law or the lever balance principle of forces to determine the mass of an object. A weighing instrument mainly consists of three parts: a load-bearing system (such as the weighing pan), a force transmission system (such as a lever transmission system), and a display system (such as a scale). Weighing instruments can be classified into three main categories according to their structural principles: mechanical scales, electronic scales, and electromechanical scales. With the development of technology, electronic scales mostly incorporate integrated circuit boards (or motherboards) to meet more needs. In independently developed electronic scales, such as label scales or PC scales, due to functional iterations or changes in motherboard manufacturers, it is necessary to modify the existing motherboard. The spacing of the screw holes (or mounting holes) fixing the motherboards of different series or manufacturers is mostly inconsistent. To adapt to each replacement, a symmetrical body (or main body) needs to be modified, for example, by adding screw posts (or connecting posts with internal threaded holes), while also considering avoiding the original fixing structure. Therefore, replacing the motherboard is very inconvenient. Furthermore, the number of times the mold can be modified is limited; after a certain number of modifications, the entire mold needs to be replaced, increasing costs.

[0003] In view of this, the inventors have specifically designed a fixing structure and a weighing instrument that are adapted to different circuit boards, and this invention is thus derived. Utility Model Content

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0021] Please see Figures 1 to 5 This is a fixing structure, as an embodiment of the present invention (2011), adapted to different circuit boards 003. The fixing structure is mounted on the main body 001 and includes: two first adjusting seats 10 arranged side-by-side on the main body 001; two second adjusting seats 20 arranged side-by-side, intersecting with the first adjusting seats 10, with both ends of any one second adjusting seat 20 connected to the two first adjusting seats 10 respectively; the distance between the two second adjusting seats 20 is adjustable according to different circuit board 003 models. The fixing structure of this invention, by setting the first adjusting seats 10 and the second adjusting seats 20, wherein the distance between the second adjusting seats 20 can be adjusted according to the circuit board 003 model, thus achieving adaptation of circuit boards 003 of different specifications through the first adjusting seats 10 and the second adjusting seats 20.

[0022] Please refer to details. Figure 2The main body 001 is provided with several connecting posts 002 for mounting the first adjusting seat 10, and the first adjusting seat 10 is mounted on the connecting posts 002 via first locking members 30. When any one of the first adjusting seats 10 is installed, it is connected to two corresponding connecting posts 002 via two first locking members 30. The two first locking members 30 pass through the first adjusting seat 10 and are connected to the two corresponding connecting posts 002. That is, when the first adjusting seat 10 is installed, it is placed on top of the two connecting posts 002, and the first locking members 30 pass through the first adjusting seat 10 and are connected to the connecting posts 002. The connecting posts 002 are provided with internal threaded holes, and the first locking members 30 can be flat-head screws. The first locking members 30 pass through the first adjusting seat 10 and are connected to the internal threaded holes on the connecting posts 002.

[0023] Please refer to details. Figure 3 At least one elongated first connecting hole 11 is provided on the first adjusting seat 10 along its long axis. A first groove 12 is also provided on the first adjusting seat 10. The first connecting hole 11 is located at the bottom of the first groove 12. When multiple first connecting holes 11 are provided, they are arranged in a linear array. When the first locking member 30 is locked, its head (the head of the flat-head screw) is located in the first groove 12, preventing the top of the first locking member 30 from being higher than the surface of the first adjusting seat 10 and affecting subsequent installation. After passing through the first connecting hole 11, the first locking member 30 connects to the internal threaded hole on the connecting post 002. Since the specifications of the main body 001 are different, the center distance between any two connecting posts 002 on the body may be the same. Therefore, the first connecting hole 11 is elongated to accommodate different specifications of the main body 001. That is, the elongated first connecting hole 11 can be directly adapted, improving the applicability of the fixing structure.

[0024] Please refer to details. Figure 2 The second adjusting seat 20 is mounted on the first adjusting seat 10 via a second locking member 40. When any one of the second adjusting seats 20 is installed, it spans across the two first adjusting seats 10, and is connected to the second section via two second locking members 40. Each of the two second locking members 40 passes through the second adjusting seat 20 and connects to the corresponding first adjusting seats 10. That is, when installing the second adjusting seat 20, it is placed above the two first adjusting seats 10, and the second locking member 40 passes through the second adjusting seat 20 and connects to the first connecting hole 11. The second locking member 40 can be a flat-head screw; it simply passes through the second adjusting seat 20 and connects to the first connecting hole 11. After connection, the second adjusting seats 20 of this invention are perpendicular to the first adjusting seats 10, meaning the two first adjusting seats 10 are parallel to each other, and the two second adjusting seats 20 are perpendicular to the first adjusting seats 10 and parallel to each other.

[0025] Please refer to details. Figure 4The second adjusting seat 20 has at least one elongated second connecting hole 21 along its long axis. The second adjusting seat 20 also has a second groove 22. The second connecting holes 21 are located at the bottom of the second groove 22, and when multiple holes are provided, they are arranged in a linear array. When the second locking member 40 is locked, its head is located in the second groove 22, preventing the top of the second locking member 40 from being higher than the surface of the second adjusting seat 20.

[0026] Please refer to details. Figure 1 , 2 The circuit board 003 has mounting holes 004 and is positioned above the two second adjusting seats 20 via a third locking member 50. Existing, normal circuit boards 003 have four mounting holes 004, and the mounting holes 004 may differ for different specifications of circuit boards 003. Therefore, the distance between the two second adjusting seats 20 can be adjusted according to the spacing between adjacent mounting holes 004. After adjustment, the circuit board 003 is placed on the two second adjusting seats 20, and connected to the second connecting hole 21 via the third locking member 50 passing through the mounting holes 004. Since the second connecting hole 21 is elongated, it can be directly installed.

[0027] In summary, the second locking member 40 passes through the second connecting hole 21 and connects to the first connecting hole 11 on the first adjusting seat 10. Since the first connecting hole 11 and the second connecting hole 21 are elongated, they can be adapted to the installation of circuit boards 003 of different specifications. Specifically, the spacing between the two second adjusting seats 20 can be adjusted according to the spacing between the mounting holes 004 on the circuit board 003. That is, since the center distance between the two mounting holes 004 on the circuit board 003 is not necessarily the same, the elongated first connecting hole 11 and the second connecting hole 21 can be directly adapted, improving the applicability of the fixing structure. When installing this utility model, first place the first adjusting seat 10 on the connecting post 002, and connect it to the connecting post 002 by passing the first locking member 30 through the first connecting hole 11. After the two first adjusting seats 10 are installed in place, place the second adjusting seat 20 on the first adjusting seat 10, and connect it to the first connecting hole 11 by passing the second locking member 40 through the second connecting hole 21. After the two second adjusting seats 20 are installed in place, place the circuit board 003 on the two second adjusting seats 20, and connect it to the second connecting hole 21 by passing the third locking member 50 through the mounting hole 004.

The fixing structure adopts a fixing structure adapted to different circuit boards 003 in embodiment 1. The weighing instrument also includes a housing 005 disposed on the main body 001.

[0029] In summary, the fixing structure of this utility model, by setting a first adjusting seat and a second adjusting seat, wherein the distance between the second adjusting seats can be adjusted according to the circuit board model, achieves the adaptation of circuit boards of different specifications through the first adjusting seat and the second adjusting seat. Therefore, the fixing structure of this utility model has strong adaptability, strong compatibility with weighing instruments, and can also save mold repair costs.
