It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0025] Embodiment One

[0026] As shown in Figures 1-3 , a monitoring device positioning structure is provided, comprising a bottom plate 100, a top plate 200, at least two protruding blocks 110, at least two recessed blocks 210, at least two fixing rods 300 and an adjusting piece 400;

[0027] The bottom plate 100 has a first support surface facing the top plate 200, and the top plate 200 has a second support surface facing the bottom plate 100, and the first support surface and the second support surface are arranged in parallel with each other;

[0028] The protruding block 110 is protrudingly arranged on the first support surface, and the recessed block 210 is arranged on the second support surface, and the end of the recessed block 210 is recessedly arranged with a positioning groove 250, and the protruding block 110 is arranged in the positioning groove 250 and abuts against the side wall of the positioning groove 250;

[0029] The protruding block 110 is provided with a first through hole 120 along the direction from one end close to the second support surface to the other end, the recessed block 210 is provided with a second through hole 220 along the direction from one end close to the first support surface to the other end, the bottom plate 100 is provided with a bottom through hole aligned with the first through hole 120 and in communication with each other, the top plate 200 is provided with a top through hole aligned with the second through hole 220 and in communication with each other, and the fixing rod 300 is connected with the adjusting piece 400 by sequentially penetrating through the bottom through hole, the first through hole 120, the second through hole 220 and the top through hole, and the fixing rod 300 and the adjusting piece 400 abut against the opposite faces of the bottom plate 100 and the top plate 200, respectively.

[0030] In the embodiment, when the top plate 200 and the bottom plate 100 are installed, the bottom plate 100 and the top plate 200 are parallel to each other, and the protrusions 110 on the bottom plate 100 are inserted into the positioning grooves 250 of the top plate 200, and the protrusions 110 abut against the sidewalls of the positioning grooves 250 to limit the movement between the protrusions 110 and the recesses 210. At this time, the first through hole 120 and the second through hole 220 are aligned. The length of the fixing rod 300 is greater than the sum of the thicknesses of the bottom plate 100, the recesses 210, the protrusions 110, and the top plate 200, and the first end of the fixing rod 300 abuts against the side of the top plate 200 or the bottom plate 100 away from the other, and the second end of the fixing rod 300 passes through the bottom through hole, the first through hole 120, the second through hole 220, and the top through hole in sequence to limit the dislocation movement of the top plate 200 and the bottom plate 100. The adjusting piece 400 is connected to the second end of the fixing rod 300, and the adjusting piece 400 abuts against the side of the bottom plate 100 or the top plate 200 away from the other to adjust the distance between the top plate 200 and the bottom plate 100. At least two recesses 210 are arranged on the top plate 200, and at least two protrusions 110 are arranged on the bottom plate 100. When the top plate 200 and the bottom plate 100 are installed, one protrusion 110 is inserted into one recess 210, and the plurality of protrusions 110 and the plurality of recesses 210 cooperate with each other to limit the relative rotation of the top plate 200 and the bottom plate 100.

[0031] As shown in Figure 2 and Figure 3 In one embodiment, three protrusions 110 are arranged on the bottom plate 100 in a triangular distribution, and three recesses 210 are arranged on the top plate 200 in a triangular distribution, and the three protrusions 110 are respectively inserted into the three recesses 210.

[0032] In the embodiment, the three protrusions 110 are arranged in a triangular distribution, and the three recesses 210 are arranged in a triangular distribution, so that when the top plate 200 and the bottom plate 100 are relatively installed, the three protrusions 110 are respectively inserted into the three recesses 210, and the three protrusions 110 and the three recesses 210 cooperate with each other to limit the relative rotation of the top plate 200 and the bottom plate 100.

[0033] As shown in Figure 2 and Figure 3 In one embodiment, the protrusion 110 is arranged as a convex spherical surface 130 away from the first supporting surface of the bottom plate 100.

[0034] In the embodiment, the protrusion 110 is arranged as a convex spherical surface 130 away from the first supporting surface of the bottom plate 100, and the curvature of the convex spherical surface 130 is used so that when the protrusion 110 abuts against the edge of the positioning groove 250, the edge of the recess 210 slides along the convex spherical surface 130, so that the protrusion 110 can be automatically inserted into the recess 210.

[0035] In one embodiment, the positioning slot 250 may be a square hole slot or a round hole slot.

[0036] In this embodiment, the protrusion 110 is inserted into the positioning groove 250. When the positioning groove 250 is a square hole groove, the length of the shortest side of the square hole groove is greater than the diameter of the convex spherical surface 130. When the convex spherical surface 130 of the protrusion 110 abuts the edge of the positioning groove, the curvature of the convex spherical surface 130 allows the protrusion 110 to be automatically inserted into the positioning groove 250. When the positioning groove 250 is a round hole groove, the diameter of the positioning groove 250 is greater than the diameter of the convex spherical surface 130. After the protrusion 110 is inserted into the positioning groove 250, the gap between the edge of the positioning groove 250 and each side wall of the protrusion 110 is smaller, thereby facilitating precise assembly between the protrusion 110 and the recessed block 210.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, the sidewall shape of the positioning groove 250 is a concave spherical surface 230 .

[0038] In this embodiment, the side wall of the positioning groove 250 is set to a concave spherical surface 230, which is used to adapt to the convex spherical surface 130 in the protrusion 110, so that the protrusion 110 can fit more closely with the side wall of the positioning groove 250, which is beneficial to improving the stability between the top plate 200 and the bottom plate 100.

[0039] like Figures 1-3 As shown, in one embodiment, the width of the first end of the fixing rod 300 is greater than the width of the top through hole or the bottom through hole, the first end of the fixing rod 300 abuts against the side of the top plate 200 facing away from the bottom plate 100, the second end of the fixing rod 300 passes through the top through hole or the bottom through hole, the second end of the fixing rod 300 is provided with a threaded structure, the adjusting member 400 is a nut, the nut abuts against the side of the bottom plate 100 facing away from the top plate 200, and the nut is threadedly connected to the second end of the fixing rod 300.

[0040] In this embodiment, the width of the first end of the fixing rod 300 is greater than the widths of the top through-hole and the bottom through-hole. This allows the fixing rod 300 to abut the side of the top plate 200 facing away from the bottom plate 100, while the second end of the fixing rod 300 passes through the bottom through-hole, the first through-hole 120, the second through-hole 220, and the top through-hole. The nut is threadedly connected to the second end of the fixing rod 300, and the nut abuts the side of the bottom plate 100 facing away from the top plate 200. When the first end of the fixing rod 300 abuts the side of the bottom plate 100 facing away from the top plate 200, the second end of the fixing rod 300 passes through the bottom through-hole, the first through-hole 120, the second through-hole 220, and the top through-hole. The nut is threadedly connected to the second end of the fixing rod 300, and the nut abuts the side of the top plate 200 facing away from the bottom plate 100.

[0041] As Figure 3 shown, in one embodiment, the concave block 210 is protruded on the second support surface.

[0042] In this embodiment, the concave block 210 is protruded on the second support surface, so that when the top plate 200 and the bottom plate 100 are installed, the distance between the top plate 200 and the bottom plate 100 is at least the height of the concave block 210, thereby reserving a gap between the top plate 200 and the bottom plate 100, which can not only facilitate the evaporation of rainwater remaining on the first support surface or the second support surface, but also reduce the influence of dust and other sundries on the top plate 200 or the bottom plate 100. The monitoring device positioning structure can be applied to dusty and rainy environments.

[0043] As Figure 2 shown, in one embodiment, the convex block 110 is welded with the bottom plate 100.

[0044] In this embodiment, the convex block 110 is welded with the bottom plate 100, which is conducive to improving the connection strength between the convex block 110 and the bottom plate 100, so that when the top plate 200 and the bottom plate 100 are installed, they are more stable.

[0045] As Figure 3 shown, in one embodiment, the concave block 210 is welded with the top plate 200.

[0046] In this embodiment, the concave block 210 is welded with the top plate 200, which is conducive to improving the connection strength between the concave block 210 and the top plate 200, so that when the top plate 200 and the bottom plate 100 are installed, the connection between the top plate 200 and the bottom plate 100 is more stable.

[0047] As Figure 3 shown, in one embodiment, a leakage hole 240 is formed in the concave block 210, a first end of the leakage hole 240 is formed on the side wall of the concave block 210, a second end of the leakage hole 240 is formed on the surface of the positioning groove 250, and the leakage hole 240 penetrates from the outer surface of the concave block 210 to the side wall of the positioning groove 250.

[0048] In this embodiment, the leakage hole 240 is formed in the concave block 210, and the leakage hole 240 is used to communicate the side wall of the positioning groove 250 with the side wall of the concave block 210. When sundries or rainwater fall into the positioning groove 250, the sundries or rainwater can be discharged to the outside of the concave block 210 through the leakage hole 240, thereby avoiding the influence of the sundries or rainwater on the process of inserting the convex block 110 into the positioning groove 250.

[0049] As Figure 1 and Figure 3 shown, in one embodiment, the leakage hole 240 is inclined from the second end to the first end along the direction towards the second support surface of the top plate 200.

[0050] In the embodiment, the leakage hole 240 is arranged obliquely along the direction from the second end to the first end towards the second supporting surface of the top plate 200, and the first end of the leakage hole 240 is towards the second supporting surface of the top plate 200. When the top plate 200 is installed below the bottom plate 100, the sundries or rainwater falling into the positioning groove 250 automatically slide along the oblique leakage hole 240 towards the second supporting surface of the top plate 200 under the action of gravity, reducing the possibility of sundries remaining inside the positioning groove 250, reducing the influence of sundries on the insertion of the protrusion 110 and the concave block 210, and facilitating more accurate butt joint of the protrusion 110 and the concave block 210.

[0053] In the embodiment, when the monitoring device is installed on the side away from the first supporting surface of the top plate, the top plate is opposite to the bottom plate, so that the concave blocks in the top plate and the protrusions of the bottom plate are respectively inserted and matched, and the mutual limiting and matching of the plurality of protrusions and the plurality of concave blocks enable the top plate and the bottom plate to be quickly aligned and installed, thereby improving the installation speed of the top plate and the bottom plate. The relative rotation of the top plate and the bottom plate is limited, which is conducive to improving the stability of the monitoring device in the installed state.
