[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "top", "bottom", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Secondly, the terms "second" and "first" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "second" or "first" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Furthermore, any two of the terms "first direction," "second direction," and "third direction" are perpendicular to each other. For "first direction," please refer to... Figure 1 and Figure 2 The X-axis direction in the diagram; the "second direction" can be referenced. Figure 1 and Figure 2 The Y-axis direction in the figure, the "third direction" can be referred to Figure 1 and Figure 2 The Z-axis direction in the equation.

[0028] In one embodiment, reference is made to Figures 1 to 4 As shown, this utility model provides a circuit board structure, which includes a limiting member 1, a socket 2, a circuit board 3, and a substrate 4. The limiting member 1, the socket 2, and the circuit board 3 are all disposed on the same side of the substrate 4. The circuit board 3 is inserted into the socket 2 in a direction generally perpendicular to the substrate 4. The limiting member 1 is disposed on the side of the circuit board 3 in a first direction and is generally perpendicular to the circuit board 3 and the substrate 4.

[0029] Specifically, the limiting member 1 includes a limiting groove 122 and a limiting part 123. The limiting groove 122 and the limiting part 123 are located on the same side of the limiting member 1 and both face the circuit board 3. The circuit board 3 includes a plug-in part 31 and a limiting slot 32. The plug-in part 31 is located on the side of the circuit board 3 near the socket 2 and is inserted into the socket 2. The limiting slot 32 is located on the side of the circuit board 3 near the limiting member 1 and engages with the limiting part 123 of the limiting member 1. At least part of the side of the circuit board 3 near the limiting member 1 is inserted into the limiting groove 122.

[0030] According to the above structural design, in the first direction, the socket 2 cooperates with the insertion part 31 of the circuit board 3, which can restrict the movement of the circuit board 3 in the first direction. In addition, the bottom of the limiting through groove 122 (i.e., the groove wall of the limiting through groove 122 facing the circuit board 3) can also cooperate with the circuit board 3 to restrict the movement of the circuit board 3 towards the limiting member 1.

[0031] In the second direction, the socket 2 engages with the insertion portion 31 of the circuit board 3, thereby restricting the movement of the circuit board 3 in the second direction. Furthermore, the two groove walls within the limiting through groove 122, which are arranged opposite each other in the second direction, engage with the circuit board 3, thereby restricting the movement of the circuit board 3 in the second direction.

[0032] In the third direction, the limiting part 123 and the limiting slot 32 are arranged opposite to each other in the third direction, which can restrict the movement of the circuit board 3 in the third direction.

[0033] In one embodiment, reference is made to Figure 1 and Figure 2 As shown, the limiting member 1 includes a fixing part 11 and a plate part 12. The fixing part 11 is fixed to the substrate 4 by bolts. The plate part 12 extends from the side of the fixing part 11 away from the substrate 4 along a third direction, and the fixing part 11 protrudes from the plate part 12 in a direction away from the circuit board 3.

[0034] Furthermore, both the limiting groove 122 and the limiting part 123 are provided on the side of the plate part 12 near the circuit board 3.

[0035] In one embodiment, reference is made to Figure 2 As shown, the fixing part 11 of the limiting member 1 is provided with a hollow part 112. The hollow part 112 is provided with a first stud 111 extending toward the substrate 4. The substrate 4 is provided with a second stud 41. The second stud 41 cooperates with the first stud 111 and abuts against the first stud 111. The first stud 111 and the second stud 41 are internally threaded with bolts to fix the limiting member 1 on the substrate 4.

[0036] Furthermore, a bolt mounting port communicating with the first stud 111 is formed on the fixing part 11. The bolt mounting port is located on the side of the plate part 12 away from the circuit board 3, so that the operator can install the bolt into the interior of the first stud 111 and the second stud 41.

[0037] In one embodiment, the plate portion 12 of the limiting member 1 is provided with a pair of limiting plates 121, each pair of limiting plates 121 extending along a first direction and arranged along a second direction. The space between each pair of limiting plates 121 forms a limiting groove 122, and a limiting surface 124 is formed on the surface of the plate portion 12 near the circuit board 3, the limiting surface 124 overlapping the bottom of the limiting groove 122. The side of the circuit board 3 near the limiting member 1 abuts against the limiting surface 124, thereby restricting the movement of the circuit board 3 toward the direction of the limiting member 1.

[0038] Furthermore, in order to improve the limiting effect of the limiting plate 121 on the circuit board 3, in the area where the limiting plate 121 and the circuit board 3 cooperate, the spacing between each pair of limiting plates 121 in the second direction is equal to the thickness of the circuit board 3 in the second direction, that is, the groove width of the limiting through groove 122 in the second direction is equal to the thickness of the circuit board 3 in the second direction, so that the circuit board 3 fits as closely as possible to a pair of limiting plates 121, reducing the gap between the circuit board 3 and the limiting plate 121, and improving the limiting effect of the limiting member 1 on the circuit board 3 in the second direction.

[0039] In one embodiment, reference is made to Figure 2 and Figure 4 As shown, the plate portion 12 of the limiting member 1 is provided with multiple pairs of limiting plates 121 arranged along the second direction, and multiple limiting slots 122 are formed on the plate portion 12. The base plate 4 is provided with multiple sockets 2 and multiple circuit boards 3. The multiple limiting slots 122, multiple sockets 2 and multiple circuit boards 3 are mutually plugged in and engaged in a one-to-one correspondence. The limiting part 123 has a certain length in the second direction so that the limiting part 123 can cooperate with the limiting slot 32 on each circuit board 3, so as to fix multiple circuit boards 3 simultaneously by a single limiting member 1.

[0040] In one embodiment, the limiting portion 123 is formed by bending from the side of the limiting member 1 away from the substrate 4, and the limiting portion 123 extends substantially along the second direction after bending.

[0041] In one embodiment, the width of the slot of the limiting slot 32 in the third direction is equal to the thickness of the limiting part 123 in the third direction, so as to minimize the gap between the limiting slot 32 and the limiting part 123 and improve the limiting effect of the limiting member 1 on the circuit board 3 in the third direction.

[0042] In one embodiment, reference is made to Figure 3 As shown, on the side near the socket 2, the circuit board 3 has a pair of clearance grooves 33 arranged in the first direction, and the circuit board 3 forms a plug portion 31 in the area between the pair of clearance grooves 33.

[0043] When the plug part 31 is inserted into the socket 2, the two shell walls of the socket 2, which are arranged opposite each other in the first direction, are respectively located in the two clearance grooves 33 and cooperate with the two clearance grooves 33 to restrict the movement of the circuit board 3 in the first direction.

[0044] In another embodiment, when the plug portion 31 is disposed in the edge area of ​​the circuit board 3, one side of the plug portion 31 in the first direction has no solid structure and does not need to avoid the shell wall of the socket 2. In this case, only an avoidance groove 33 needs to be provided on the other side of the plug portion 31 in the first direction.

[0045] In one embodiment, the present invention also provides a weighing instrument, which includes the circuit board structure described in the above embodiment.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
