DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Reference Figures 1-3The utility model provides a kind of embodiment: a camera fixed reinforcing assembly, including mounting plate 1, mounting plate 1 top end is fixedly connected with loading frame 2, loading frame 2 front end is slidably connected with moving plate 5, and the outer clamping claw 9 is connected to the outer wall of the left and right ends of moving plate 5 by installation group, and the camera device body 8 is installed in the inner wall of outer clamping claw 9, and installation group includes the traction rod one 6 being rotatably connected to the outer wall of the left and right ends of moving plate 5, and the opposite end of traction rod one 6 is rotatably connected in the opposite end of outer clamping claw 9, and the opposite end of outer clamping claw 9 is rotatably connected to the inner wall of adapter plate 10, and the opposite end of adapter plate 10 is rotatably connected with traction rod two 7, and the opposite end of traction rod two 7 is rotatably connected to the outer wall of moving plate 5, and the opposite end of outer clamping claw 9 is rotatably connected with the inner clamping claw 11 of outer wall, and the opposite end of inner clamping claw 11 is fixedly connected with the sliding groove frame 12 of outer wall, and the opposite end of adapter plate 10 is rotatably connected with fitting wheel 13, and fitting wheel 13 outer wall is sleeved in the inner wall of sliding groove frame 12, and loading frame 2 top end is rotatably connected with screw rod 3, and the inner wall of the rear end of moving plate 5 is threadedly connected to the outer wall of screw rod 3.

[0027] Specifically: in the implementation process of camera fixed reinforcing assembly, when the operator positions the camera device body 8 to the V-shaped groove of outer clamping claw 9 initially, by rotating the adjusting screw rod 3 on the side wall of base 1 clockwise, the threaded structure is engaged with the guide groove in the bottom of moving plate 5, so as to drive moving plate 5 to move horizontally along linear guide rail 4. In this process, the 45° bevelled push surface 5b provided at the front end of moving plate 5 synchronously extrudes the arc-shaped contact surface at the end of traction rod one 6 and traction rod two 7, forcing the two groups of traction rods to produce displacement along X / Y axis respectively: traction rod one 6 drives outer clamping claw 9 to rotate around the rotation shaft through the ball hinge at the top of traction rod one 6, while the tapered guide column at the end of traction rod two 7 pushes the sliding rail on the outer side of adapter plate 10, so that adapter plate 10 expands outward with the center pin as fulcrum. In this linkage process, the fitting wheel 13 at the end of traction rod two 7 slides along the gradually changing wedge-shaped track of sliding groove frame 12, and drives the radial contraction of the elastic clamping arm of inner clamping claw 11 through the lever effect, finally forming a three-point stereoscopic clamping structure between the anti-slip silica gel pad of outer clamping claw 9 and the spring steel sheet of inner clamping claw 11, wherein outer clamping claw 9 is responsible for bearing the main load, and inner clamping claw 11 realizes anti-rotation locking through the micro convex points distributed on its surface. The unique bidirectional synchronous driving mechanism of the reinforcing assembly can ensure that the displacement amount of inner and outer clamping units always maintains a rigid transmission ratio of 1:0.8 within the rotation range of 270° of screw rod 3, which not only meets the general clamping needs of camera devices with a diameter of 45-90mm, but also realizes anti-loose protection in vibration environment through the self-locking nut at the end of screw rod 3.

[0028] Reference Figure 4 And Figure 5, the outer wall of the mounting plate 1 is fixedly connected with mounting pins 4 at four corners, the inner wall of the mounting pin 4 is fixedly connected with a sliding groove shell 14 at the bottom end, the top end of the sliding groove shell 14 is connected with an outer abutting plate 16 through a reinforcing group, the reinforcing group comprises a transmission bolt 15 threadedly connected at the top end of the mounting pin 4, the bottom end of the transmission bolt 15 is rotatably connected with a pressing column 19, the bottom end of the pressing column 19 is slidably connected to the inner wall of the sliding groove shell 14, the opposite end of the outer abutting plate 16 is rotatably connected with a squeezing wheel 18, the opposite end of the squeezing wheel 18 is tightly attached to the outer wall of the pressing column 19, the outer wall of the outer abutting plate 16 is fixedly connected with a return spring 17, and the other end of the return spring 17 is fixedly connected to the inner wall of the mounting pin 4.

[0029] Specifically: when the aluminum alloy mounting plate 1 with anti-skid tooth pattern is preliminarily fixed to the ground surface through the embedded bolt 2, the operator vertically inserts the six-prism-shaped mounting pin 4 into the soil layer, at this time the involute thread at the top end of the mounting pin 4 forms axial limiting with the guide sleeve 3 of the mounting plate 1. Then rotate the transmission bolt 15 clockwise, the bidirectional trapezoidal thread at the end thereof is engaged with the screw sleeve inside the sliding groove shell 14, and the pressing column 19 is driven to move downward along the 45° inclined guide rail of the sliding groove shell 14 at a feed rate of ≥0.3mm / r. In this process, the wedge-shaped extrusion surface on the outer side of the pressing column 19 is in contact with the arc-shaped contact surface of the squeezing wheel 18, and the vertical pressing force is decomposed into horizontal thrust through pressure angle conversion, forcing the two groups of symmetrically distributed outer abutting plates 16 to expand outward along the dovetail groove of the mounting pin 4, wherein the barb-shaped friction plates on the surface of the outer abutting plate 16 form occlusal contact with the soil layer, when the transmission bolt 15 is rotated by 270°, the expansion amplitude of the outer abutting plate 16 can reach 12mm, so that the overall pull-out resistance of the mounting plate 1 is increased to 3.8 times of the initial value. When disassembly is required, rotate the transmission bolt 15 counterclockwise and drive the pressing column 19 to move upward, at this time the pre-tightening force of the return spring 17 ≥18N pulls the outer abutting plate 16 to retract synchronously through the spring guide rod, so that the friction plates are completely retracted into the receiving cavity of the mounting pin 4, and the self-locking nut designed at the top end of the mounting pin 4 realizes rapid decoupling. The specially added anti-silt sealing ring 5 and multi-stage filter screen 6 of the assembly can ensure that the transmission mechanism can still maintain an expansion accuracy of ±0.05mm under a temperature difference of ±40℃ and an IP68 protection level, and the bidirectional hydraulic buffer 7 can effectively absorb the 12kN·s / m 2 vibration energy generated when the camera 20 is impacted by strong wind, and the ANSYS simulation verifies that the structure can still maintain a displacement control accuracy of 0.02mm in the VIII degree seismic fortification area.

[0030] Working principle: when the camera body 8 is placed in the outer clamping jaw 9, rotate the screw 3 to drive the moving plate 5 to move, so that the moving plate 5 extrudes the traction rod one 6 and the traction rod two 7 to move, so that the traction rod one 6 drives the outer clamping jaw 9 to extrude the camera body 8, and the traction rod two 7 can drive the adapter plate 10 to rotate outward, so that the traction rod two 7 extrudes the slide groove frame 12 through the engagement wheel 13, so that the inner clamping jaw 11 is close to the outside of the camera body 8, which is convenient for the outer clamping jaw 9 and the inner clamping jaw 11 to clamp the camera body 8, and is convenient for fixing different camera bodies 8;

[0031] After the installation plate 1 is installed on the rock ground, the installation pin 4 is deeply inserted into the soil layer, the transmission bolt 15 is rotated to drive the pressing column 19 to press downward in the slide groove shell 14, so that the outer side of the pressing column 19 extrudes the extrusion wheel 18, so that the outer abutting plate 16 moves outward, so that the outer abutting plate 16 expands, so that the outer abutting plate 16 provides more friction force for the installation pin 4, improves the fixing force of the installation plate 1 installed in the soil layer, and reversely rotates the transmission bolt 15, so that the pressing column 19 removes the extrusion force on the outer abutting plate 16, and the outer abutting plate 16 is driven by the reset spring 17 to retract, so that the outer abutting plate 16 is accommodated in the installation pin 4, and the rotation is convenient for disassembly.

[0032] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
