Description

Technical Field

[0001] The invention relates to the technical field of lightning protection detection equipment, in particular to a bracket for lightning protection detection. Background Art

[0002] Lightning protection detection is an important measure to ensure that buildings, facilities and equipment can effectively resist lightning strikes. The lightning protection detection recorder is a device specially used to record various parameters and data during the detection process of the lightning protection system. It can help inspectors accurately capture and save test results to ensure the integrity and reliability of the data. The lightning protection detection recorder is basically fixed directly on the mounting base through multiple bolts, and then the mounting base is directly placed on the ground or mounting surface near the detection point, and then the lightning protection detection recorder carries out the detection operation.

[0003] However, the above installation method is prone to the following problems: 1. When the mounting base is not fixed with restrictions, it is easy to be offset by external force, which will cause the detection stability of the lightning protection detection recorder to be significantly reduced, and the detection will be directly affected, resulting in unstable or inaccurate measurement results.

[0004] 2. When the recorder needs to be maintained, calibrated or replaced, the multiple bolt fixing method may make the disassembly and assembly process cumbersome, especially when the bolts are rusted or over-tightened. At the same time, once the installation is completed, if only the position or angle of the recorder needs to be adjusted, the multiple bolt fixing method will appear inflexible.

[0033] Please refer to Figure 1 and Figure 3 , the locking mechanism 2 includes a connection ring 21 sleeved outside the support plate 11 and coaxial with it, a plurality of pressure rods 22 are installed circumferentially and uniformly at the top of the connection ring 21, and a first connection component 24 is installed on the connection ring 21.

[0034] See also Figure 1 and Figure 4 The triangular fixing mechanism 3 includes a plurality of bidirectional elastic telescopic rods 31 distributed in an equilateral triangle, a pressing plate 32 is fixedly connected between the ends of the corresponding telescopic sections of two adjacent bidirectional elastic telescopic rods 31, and a plug-in block 33 is fixedly connected to the bottom of the pressing plate 32.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The clamping mechanism 4 includes an electric telescopic rod 41 fixedly connected to the bottom center of the support plate 11, a clamping block 42 is fixedly connected to the bottom of the telescopic section of the electric telescopic rod 41, and a plurality of elastic telescopic rods 43 are evenly installed circumferentially on the telescopic section of the electric telescopic rod 41 and located above the clamping block 42. A connecting component 2 44 for locking the bidirectional elastic telescopic rod 31 is installed at the end of the telescopic section of the elastic telescopic rod 1 43, and a linkage component 45 that is clamped with the connecting component 1 24 is installed on the top of the fixed section. A positioning component 15 for limiting the linkage component 45 is also installed on the support mechanism 1.

[0036] See also Figure 1 , Figure 2 and Figure 7 A rectangular rubber pad is provided on the top of the turntable 13, and a clamping assembly 14 for clamping the recorder is also installed on the top of the turntable 13. The clamping assembly 14 includes two slide grooves 141 opened on the top of the turntable 13 and parallel to one of the diagonals of the rectangular rubber pad. The two slide grooves 141 correspond to the two ends of the diagonal respectively. A threaded rod 142 is installed between the two slide grooves 141 for common rotation. An L-shaped clamping plate 143 is installed on the top of the slide groove 141 for sliding along the axial direction of the threaded rod 142. The bottom of the L-shaped clamping plate 143 is threadedly connected to the threaded rod 142. A rubber layer is provided on the inner side of the upper part of the L-shaped clamping plate 143. A knob 144 is fixedly connected to one end of the threaded rod 142. A groove for the knob 144 to rotate is provided on the turntable 13.

[0037] When installing the recorder, place the recorder on the rectangular rubber pad on the top of the turntable 13, align one of the diagonals of the bottom surface of the recorder with the two L-shaped clamps 143, and then turn the knob 144 to drive the threaded rod 142 to rotate. The threaded rod 142 is a bidirectional threaded rod provided with two threaded sections with opposite rotation directions. The threaded rod 142 is used to drive the L-shaped clamps 143 threadedly connected thereto to move inward, and the two L-shaped clamps 143 move toward each other, so that the L-shaped clamps 143 clamp the diagonal position of the recorder to prevent the recorder from moving on the turntable 13. The rectangular rubber pad and the rubber layer can play a role in buffering protection and increasing friction, thereby avoiding damage to the recorder and improving the clamping stability.

[0038] See also Figure 1, Figure 2 , Figure 3 and Figure 5 , the shape of the compression bar 22 is a stepped structure with two layers of steps. A rubber layer is installed at the bottom of the upper step, and a plug rod 23 is fixedly connected to the bottom of the lower step. A number of upper and lower through limiting holes 131 are evenly distributed in the circumferential direction on the turntable 13, and the plug rod 23 is inserted and matched with the corresponding limiting hole 131.

[0039] After the recorder is fixed by the clamping assembly 14, the telescopic section of the electric telescopic rod 41 extends downward and drives the first elastic telescopic rod 43 to move downward synchronously. The first elastic telescopic rod 43 drives the linkage assembly 45 to move downward together. The linkage assembly 45 drives the connecting ring 21 and the compression bar 22 to move downward together. The upper step in the compression bar 22 presses tightly on the top of the recorder, improving the firmness of the recorder installed on the turntable 13. At the same time, the lower step in the compression bar 22 will press tightly on the top of the turntable 13, and after the plug rod 23 is inserted into the corresponding limiting hole 131, it abuts against the top of the support plate 11, preventing the turntable 13 from rotating and further improving the stability of the recorder installation.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 , the first connecting component 24 includes a second rotating ring 241 rotatably installed inside the connecting ring 21. A number of L-shaped locking tongues 242 are evenly installed in the circumferential direction at the bottom of the second rotating ring 241. Locking holes 211 are opened at the corresponding positions of the bottom of the connecting ring 21 for the L-shaped locking tongues 242. A fixing plate 243 is evenly connected in the circumferential direction inside the connecting ring 21 and is located below the second rotating ring 241. The fixing plate 243 is slidably connected to the second rotating ring 241. A second return spring 244 is fixedly connected between the L-shaped locking tongue 242 and the corresponding fixing plate 243. A second push plate 245 is fixedly connected to the front side of the second rotating ring 241, and a first through groove for the second push plate 245 to rotate left and right is opened on the front side of the connecting ring 21.

[0041] Please refer to Figure 1 , Figure 3 and Figure 5 , the linkage assembly 45 includes a second elastic telescopic rod 451 fixedly connected to the top of the fixed section of the first elastic telescopic rod 43 and away from the electric telescopic rod 41. The top of the telescopic section of the second elastic telescopic rod 451 is fixedly connected with a U-shaped block 452. The top of the U-shaped block 452 is fixedly connected with a U-shaped hook 453 inserted and matched with the locking hole 211. The opening of the U-shaped hook 453 faces the adjacent U-shaped block 452, and the U-shaped hook 453 is clamped and matched with the L-shaped locking tongue 242.

[0042] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 7, in the initial state, the top of the U-shaped block 452 abuts against the bottom of the connecting ring 21. At this time, the U-shaped hook 453 is inserted into the corresponding locking hole 211, and the horizontal section of the L-shaped locking tongue 242 is clamped inside the U-shaped hook 453. The U-shaped hook 453 is clamped by the L-shaped locking tongue 242, and the connecting ring 21 and the U-shaped block 452 are installed together. During the process of the electric telescopic rod 41 pushing the pressing block 42 downward, the U-shaped block 452 and the connecting ring 21 are driven by the first elastic telescopic rod 43 and the second elastic telescopic rod 451 to move downward together to fix the recorder.

[0043] When the angle of the fixed recorder needs to be adjusted, by pushing the second push plate 245 to rotate clockwise, the second push plate 245 drives the second rotating ring 241 and the L-shaped locking tongue 242 to rotate clockwise, so that the L-shaped locking tongue 242 is separated from the U-shaped hook 453, and the locking of the U-shaped hook 453 is released. At this time, the second return spring 244 is compressed. Then, the connecting ring 21 is moved upward to release the fixing of the pressure lever 22 on the recorder. At this time, the turntable 13 can be rotated to adjust the angle of the recorder. There is no need to disassemble the bolts and the clamping assembly 14 still fixes the recorder, making the adjustment more flexible. After the adjustment is completed, the connecting ring 21 is placed on the top of the U-shaped block 452 again, so that the U-shaped hook 453 is inserted into the inside of the locking hole 211. The second push plate 245 is released, and the L-shaped locking tongue 242 and the second rotating ring 241 are driven by the resilience of the second return spring 244 to rotate counterclockwise, so that the L-shaped locking tongue 242 re-clamps the U-shaped hook 453.

[0044] When the fixed recorder needs to be maintained and replaced, after releasing the fixing of the pressure lever 22 on the recorder, by rotating the knob 144 counterclockwise, the threaded rod 142 rotates counterclockwise, so that the L-shaped clamping plate 143 releases the clamping of the recorder. At this time, the turntable 13 can be maintained and replaced. Just rotating one knob 144 can release the clamping of the recorder. There is no need to disassemble too many bolts, and the disassembly and assembly are more convenient.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 4 , through holes penetrating up and down are provided on the feet of the support leg 12. The plug-in block 33 is in plug-in fit with the corresponding through hole. Anti-slip pads are installed at the bottoms of the plug-in block 33 and the pressing block 42. A guiding groove 121 is provided on one side of the support leg 12 away from the axis of the support plate 11. A roller 34 is rotatably connected to one side of the pressing plate 32 close to the axis of the support plate 11. The roller 34 is matched with the guiding groove 121; the length of the roller 34 is equal to the width of the guiding groove 121.

[0046] Please refer to Figure 1 、 Figure 5 and Figure 6The connecting component 2 44 includes a U-shaped frame 441 which is fixedly connected to the telescopic section of the elastic telescopic rod 1 43 and has an opening upward. The top of the U-shaped frame 441 close to the electric telescopic rod 41 is fixedly connected to a shell 442. The side of the shell 442 away from the electric telescopic rod 41 is slidably installed with two symmetrically distributed wedge-shaped blocks 443 along the telescopic direction of the elastic telescopic rod 1 43. A return spring 3 444 is fixedly connected between the side of the wedge-shaped block 443 close to the electric telescopic rod 41 and the inner wall of the shell 442. A push plate 3 445 is fixedly connected between the two wedge-shaped blocks 443 in the same shell 442. A slot is provided on the top of the shell 442 for the push plate 3 445 to slide along the telescopic direction of the elastic telescopic rod 1 43. The top of the push plate 3 445 extends from the slot to the top of the shell 442.

[0047] See also Figures 1 to 6 When placing the bracket, carry the support mechanism 1 to the location where lightning protection detection is required, open several support legs 12 outward at a certain angle, so that the legs of the support legs 12 are horizontally supported on the ground. By adjusting the opening angle of the support legs 12, the height of the support plate 11 can be appropriately adjusted, which is convenient for the recorder to perform detection at different heights.

[0048] After the support plate 11 is laid flat, the triangular fixing mechanism 3 is placed from top to bottom to the outside of the supporting leg 12. In the initial state, the bidirectional elastic telescopic rod 31 and the electric telescopic rod 41 are both in a retracted state. The size of the entire triangular fixing mechanism 3 is adjusted by appropriately stretching the bidirectional elastic telescopic rod 31 so that the fixed section of the bidirectional elastic telescopic rod 31 is aligned with the opening at the top of the U-shaped frame 441, and then the bidirectional elastic telescopic rod 31 is installed into the U-shaped frame 441. During installation, the fixed section of the bidirectional elastic telescopic rod 31 will first contact the inclined surface of the wedge-shaped block 443, and then the wedge-shaped block 443 will be pushed into the interior of the shell 442. At this time, the reset spring three 444 will be compressed. When the fixed section of the bidirectional elastic telescopic rod 31 is completely entered into the U-shaped frame 441, the resilience of the reset spring three 444 is used to push the wedge-shaped block 443 to move to the outside of the shell 442 and clamp the bidirectional elastic telescopic rod 31 to prevent the bidirectional elastic telescopic rod 31 from falling off from the U-shaped frame 441.

[0049] Then, the telescopic section of the electric telescopic rod 41 extends downward and drives the pressing block 42 and the elastic telescopic rod 1 43 to move downward, and the elastic telescopic rod 1 43 drives the connecting component 2 44 to move downward synchronously, and then the connecting component 2 44 drives the triangular fixing mechanism 3 to move downward, at this time, the roller 34 will fall into the guide groove 121 and move downward along the guide groove 121, and in the process of the triangular fixing mechanism 3 moving downward, the supporting leg 12 will open the triangular fixing mechanism 3 outward, so that the bidirectional elastic telescopic rod 31 and the elastic telescopic rod 1 43 are extended, and the triangular fixing mechanism 3 The whole is proportionally enlarged in the shape of an equilateral triangle. When the pressure plate 32 moves down to the foot of the supporting leg 12, the plug-in block 33 is just inserted into the through hole on the foot. The pressure plate 32 is used to press the foot of the supporting leg 12. At the same time, the plug-in block 33 contacts the ground after passing through the through hole, thereby improving the stability of the supporting leg 12. The triangular fixing mechanism 3 locks and connects several supporting legs 12 together. At the same time, the clamping block 42 also contacts the ground, thereby further improving the stability of the bracket. The anti-slip pads of the clamping block 42 and the plug-in block 33 serve to increase friction.

[0050] When the detection is completed and the bracket needs to be folded up, by pushing the push plate 3 445 to move towards the direction close to the electric telescopic rod 41, the wedge-shaped block 443 can be retracted into the interior of the shell 442 and no longer restrict the bidirectional elastic telescopic rod 31. The bidirectional elastic telescopic rod 31 can be taken out upward from the U-shaped frame 441, so that the triangular fixing mechanism 3 can be shrunk to a smaller volume and stored separately, which is more convenient to carry.

[0051] See also Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 The positioning assembly 15 includes a plurality of C-shaped sliders 151 which are slidably installed along the radial direction inside the support plate 11 and are evenly distributed in the circumferential direction. A positioning block 152 is fixedly connected to one end of the C-shaped slider 151 away from the center of the support plate 11. The end of the positioning block 152 away from the C-shaped slider 151 slides through the outside of the support plate 11. The positioning block 152 is plugged into and matched with the corresponding return block 452. A return spring 153 is fixedly connected between one side of the C-shaped slider 151 close to the center of the support plate 11 and the inner wall of the support plate 11. An unlocking assembly for driving the C-shaped slider 151 to move toward the center of the support plate 11 is installed inside the support plate 11.

[0052] See also Figure 1 and Figure 8The unlocking assembly includes a swivel ring 154 rotatably mounted inside the support plate 11 and located below the horizontal section of the C-shaped slider 151. A plurality of wedge-shaped pushing blocks 155 are provided on the inner side of the swivel ring 154. The inclined surfaces of the wedge-shaped pushing blocks 155 slide in cooperation with the inner wall of the vertical section of the C-shaped slider 151 close to the center of the support plate 11. A push plate 156 is fixedly connected to the front side of the swivel ring 154. A through slot 2 is provided on the front side of the support plate 11 for the push plate 156 to rotate left and right.

[0053] See also Figure 1 , Figure 2 , Figure 5 and Figure 8 Before the electric telescopic rod 41 pushes the clamping block 42 to move downward, the push plate 156 is pushed to rotate clockwise, and then the push plate 156 drives the swivel 154 and the wedge-shaped pushing block 155 to rotate clockwise, and the wedge-shaped pushing block 155 is used to push the C-shaped slider 151 and the positioning block 152 to retract inward to the inside of the support plate 11. At this time, the return spring 153 will be compressed to avoid affecting the linkage component 45 to drive the connecting ring 21 to move downward. When the pressure rod 22 is pressed on the recorder, the positioning block 152 is just aligned with the return block 452. At this time, the push plate 156 is rotated counterclockwise, and the resilience of the return spring 153 is used to push the C-shaped slider 151 and the positioning block 152 to move outward, so that the positioning block 152 is inserted into the return block 452, which plays a role in fixing the connecting ring 21 and the return block 452.

[0054] When the supporting angle of the supporting leg 12 is to be adjusted later, since the connecting ring 21 and the return block 452 have been fixed, the electric telescopic rod 41 will drive the triangular fixing mechanism 3 to move upward, and the elastic telescopic rod 2 451 will contract to release the pressure on the supporting leg 12, and will not drive the connecting ring 21 and the return block 452 to move together, thereby ensuring the firmness of the recorder fixation.

[0055] When disassembly is required later, push plate 156 to rotate clockwise to release the locking block 452 from the positioning block 152. At this time, the electric telescopic rod 41 drives the triangular fixing mechanism 3 to move upward, which will drive the locking mechanism 2 to move upward together, and at the same time release the fixing of the supporting leg 12 and the recorder, so as to facilitate quick disassembly.

[0056] See also Figure 2 and Fig. 9A plurality of connecting seats 111 are evenly installed on the bottom circumference of the support plate 11, and the top end of the support leg 12 is rotatably connected to the connecting seat 111 through an axle rod. An angle limiting component for limiting the rotation angle of the support leg 12 is also installed on the connecting seat 111. The angle limiting component includes an active groove 112 which is opened on the connecting seat 111 and is coaxial with the axle rod. The connecting seat 111 is also provided with an angle line for indicating the rotation angle of the support leg 12. A round rod 122 is slidably installed inside the active groove 112. One end of the round rod 122 close to the corresponding support leg 12 is fixedly connected to the support leg 12, and one end of the round rod 122 away from the corresponding support leg 12 is threadedly connected to a nut 123 located on the outside of the connecting seat 111.

[0057] After the support leg 12 is rotated outward by a certain angle, the specific angle of rotation of the support leg 12 can be determined by observing the angle line. When the support leg 12 is rotated to the required angle, the support leg 12 and the connecting seat 111 can be fastened together by tightening the nut 123, which is convenient for fixing the open angle of the support leg 12 and helps to improve the stability of the support leg 12 on the ground.
