[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", 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.
[0027] Example 1: A modular circuit board, such as Figure 1 - Figure 5 As shown, the circuit board includes a circuit board body 1 and several fastening holes 101 that penetrate the circuit board body 1. An upper fastening cylinder 2 and a lower fastening cylinder 6 are inserted into the fastening holes 101. The upper fastening cylinder 2 and the lower fastening cylinder 6 are inserted into the fastening holes 101 in opposite directions and are interlocked with each other. A positioning ring 7 is provided between the upper fastening cylinder 2 and the upper surface of the circuit board body 1, and a positioning ring 7 is provided between the lower fastening cylinder 6 and the lower surface of the circuit board body 1. The two positioning rings 7 are respectively inserted into the upper fastening cylinder 2 and the lower fastening cylinder 6. The upper fastening cylinder 2 and the lower fastening cylinder 6 are also threaded with bolts, and a connecting plate 8 for connecting support is installed on the outside of the positioning ring 7.
[0028] First, based on the insertion support of the fastening hole 101, the upper fastening cylinder 2 and the lower fastening cylinder 6 are inserted from the upper and lower ends of the fastening hole 101 respectively, and then threaded in from the middle to achieve the effect of installing and positioning the device. By adding positioning rings 7, a certain distance is maintained between the two upper fastening cylinders 2 and the lower fastening cylinder 6 and the circuit board 1. When the two circuit boards 1 are used together in the vertical direction, based on the isolation of the thickness of the two adjacent positioning rings 7 and the isolation of the contact between the upper fastening cylinder 2 and the lower fastening cylinder 6, the multiple upper fastening cylinders 2 and the lower fastening cylinder 6 distributed vertically are simultaneously fastened with bolts, so that there is a certain isolation space between the two circuit boards 1. When the device is used together in the vertical direction, it ensures the stability and safety of the connected components and effectively prevents the occupation of the single-piece usage area.
[0029] like Figure 1 - Figure 5 As shown, several fastening adjustment blocks 3 are installed at the lower end of the upper fastening cylinder 2, and an insertion space is formed between two adjacent fastening adjustment blocks 3. The connection methods of the upper fastening cylinder 2 and the lower fastening cylinder 6 are the same, and the several fastening adjustment blocks 3 on the upper fastening cylinder 2 and the several fastening adjustment blocks 3 on the lower fastening cylinder 6 are staggered and inserted into each other in the insertion space.
[0030] Guide grooves 5 are provided on the adjacent side walls of two adjacent fastening adjustment blocks 3. The guide grooves 5 are located on opposite sides of the insertion space, and sliding blocks 4 are installed on opposite sides of the fastening adjustment blocks 3. The sliding blocks 4 are slidably disposed inside the guide grooves 5.
[0031] By setting multiple fastening adjustment blocks 3 on the upper and lower fastening cylinders 2 and 6 in an interleaved insertion manner, and based on the guidance and limiting of the two sliding blocks 4 in the guide groove 5, the directional movement of the upper and lower fastening cylinders 2 and 6 is ensured to be accurate, while the distance of their mutual movement is controllable. By adding a number of positioning rings 7, the distance between the upper and lower fastening cylinders 2 and 6 is stabilized, so that they can be adjusted to a certain height within a stable range. This allows them to meet various specifications of the distance between two adjacent circuit boards 1 on the same vertical plane, and can provide guiding support for connecting components of different specifications on the circuit board 1, thereby improving the applicability of the circuit board 1 when installed vertically.
[0032] like Figure 1 - Figure 5 As shown, the inner walls of the upper fastening cylinder 2 and the fastening adjustment block 3 are provided with internal threads of the same specification, and the inner walls of the lower fastening cylinder 6 and the fastening adjustment block 3 are provided with internal threads of the same specification. The internal threads of the upper fastening cylinder 2 and the lower fastening cylinder 6 are of the same specification, and the upper fastening cylinder 2, the two fastening adjustment blocks 3, and the lower fastening cylinder 6 are all connected to the bolt threads.
[0033] When installing the two circuit boards 1 vertically, the upper fastening cylinder 2, the fastening adjustment block 3, and the lower fastening cylinder 6 have the same internal thread specification on their inner walls. This allows them to be connected and fixed to the upper fastening cylinder 2 and the lower fastening cylinder 6 simultaneously when connected to the bolts. This ensures the stability of the upper fastening cylinder 2 and the lower fastening cylinder 6 in position after being pulled and when connected. Furthermore, the connection limit between the two positioning rings 7 further improves the stability of the upper fastening cylinder 2, the lower fastening cylinder 6, and the circuit board 1 during installation and fastening.
[0034] like Figure 1 - Figure 5 As shown, the two positioning rings 7 between the upper and lower fastening cylinders 2 and 6 are respectively inserted into the outer surfaces of the fastening adjustment blocks 3 on both sides. The connecting plate 8 is equipped with a positioning arc 9 at the end away from the positioning ring 7, and the positioning arcs 9 between two adjacent positioning rings 7 are symmetrically installed. One end of the positioning arc 9 is equipped with a plug-in block 10, and the other end of the positioning arc 9 is equipped with a plug-in groove 11. Two adjacent positioning arcs 9 are connected by plug-in blocks 10 and plug-in grooves 11.
[0035] By installing a connecting plate 8 on the outside of the positioning ring 7, and interlocking the positioning arcs 9 on the two connecting plates 8, the positioning arcs 9 on both sides are positioned on the outside of the middle fastening adjustment block 3. Based on the interlocking of the two sets of interlocking blocks 10 and interlocking slots 11, the accuracy of its rotational positioning is ensured, so that it can form a precise positioning on the outside of the fastening adjustment block 3. The two positioning arcs 9 are squeezed and fastened between the upper fastening cylinder 2 and the circuit board body 1. With the bolts tightened, the overall stability of the positioning ring 7, connecting plate 8 and positioning arc 9 during installation is improved, and the uniformity and stability of the middle isolation space is ensured when the circuit board body 1 is used vertically.
[0036] Example 2: A modular circuit board, such as Figure 1 - Figure 5 As shown, a transverse combination plate 801 is installed on the outside of the positioning ring 7, which is perpendicular to the connecting plate 8. A positioning arc 9 is installed on the end of the transverse combination plate 801 away from the positioning ring 7. The connection method of the connecting plate 8 and the transverse combination plate 801 is the same.
[0037] When circuit board 1 is used in horizontal combination installation, by using it in conjunction with the horizontal combination plate 801, the positioning arc 9 on one side of the horizontal combination plate 801 is positioned on the outside of the fastening adjustment block 3 on the circuit board 1 in the same horizontal direction. By limiting the two symmetrically installed horizontal combination plates 801 at the same time, the positioning arc 9 on the horizontal combination plate 801 is positioned on the adjacent circuit board 1. By using bolts to tighten, the horizontal combination plate 801 is simultaneously tightened, so that multiple circuit boards 1 can be used in combination in both vertical and horizontal directions, improving its versatility of use.
[0038] like Figure 1 - Figure 5 As shown, an auxiliary plate 12 is provided between the two downward fastening cylinders 6. The two ends of the auxiliary plate 12 are installed on the outside of the two positioning rings 7, and the auxiliary plate 12 is located below the transverse combination plate 801.
[0039] When assembling the circuit board 1 in the horizontal direction, the positioning ring 7, the horizontal combination plate 801, and the positioning arc 9 are used separately to position and fasten it from the side of the circuit board 1. By using the auxiliary plate 12 and the lower adjustment fastening cylinder 6 for fastening, the stability of the two circuit boards 1 when used in horizontal combination is further improved.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
