[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figure 1 to Figure 7 The technical solution provides an adaptive lightning arrester mounting bracket, which includes a mounting mechanism and an adjustment mechanism, which can install the lightning arrester and adjust the inclination angle of the lightning arrester according to the actual needs of the staff.

[0028] Furthermore, the installation mechanism can increase or decrease different numbers of lightning arresters according to the needs of the staff, and includes a semicircular ring 10, a docking plate 11 on the semicircular ring 10, two semicircular plates 261, and the two semicircular plates 261 are connected by hinges. A U-shaped rod 12 is connected to the docking plate 11, and a nut 13 is provided on the U-shaped rod 12. A sliding member 14 is provided on the semicircular ring 10, a locking member 15 and a plug-in member 16 are provided on the sliding member 14, a follower 17 is provided on the locking member 15, and a guide member 18 is provided on the follower 17.

[0029] During use, when the lightning arrester needs to be installed, the staff first puts the two semicircular rings 10 on a columnar object such as a telephone pole. When the two ends of the two semicircular rings 10 are in contact, the docking plates 11 on the two semicircular rings 10 complete the contact. At this time, the staff can pass the U-shaped rod 12 through the two docking plates 11 and screw the nut 13 to fix it.

[0030] Furthermore, the sliding member 14 includes an arc groove 141 and a notch 142 at the top and bottom of the semicircular ring 10. The arc groove 141 and the notch 142 are interconnected. An L-shaped clip 143 is provided inside the arc groove 141. There are two L-shaped clips 143. One end of the two L-shaped clips 143 is respectively located inside the two arc grooves 141. The L-shaped clips 143 are connected to a base 144. One end of the two L-shaped clips 143 is located inside the arc groove 141, and the other ends of the two L-shaped clips 143 are evenly connected to the base 144.

[0031] Specifically, when the two semicircular rings 10 are connected, the two arc-shaped grooves 141 are connected to each other.

[0032] Furthermore, the locking member 15 includes a rotating column 151 on the inner wall of the base 144, the rotating column 151 and the base 144 are connected by a coil spring, and the rotating column 151 is rotatably connected to the inner wall of the base 144. When the rotating column 151 rotates, the rotating column 151 can drive the coil spring to contract, and the coil spring is used to drive the rotating column 151 to return to its initial state. A through hole 152 is opened on the rotating column 151, and a locking rod 153 is provided on the bottom of the base 144. The top of the locking rod 153 can be inserted into the inside of the through hole 152 to limit the position of the rotating column 151 and prevent the rotating column 151 from rotating. The bottom of the locking rod 153 is connected to a baffle 154, and a first spring 155 is provided on the baffle 154. The top of the first spring 155 is connected to the bottom of the base 144.

[0033] During use, when the baffle 154 is squeezed by the locking rod 153 or manually pulled, the baffle 154 will descend, and the baffle 154 can drive the first spring 155 to extend, so that the locking rod 153 is disengaged from the inside of the through-hole 152 .

[0034] Furthermore, the connector 16 includes a plug-in plate 161 on the L-shaped clip 143, a first tooth groove 162 is provided on the outer wall of the semicircular ring 10, the plug-in plate 161 is slidably connected to the L-shaped clip 143, a section 163 and a slope 164 are provided on the plug-in plate 161, the section 163 is in a "V" shape, the slope 164 is located at the top of the plug-in plate 161, a spring piece 165 is connected to the side wall of the plug-in plate 161, and a fixing block 166 is connected to the top of the plug-in plate 161.

[0035] Specifically, when the position of the base 144 is not locked, the cut surface 163 of the plug-in board 161 is partially located inside the first tooth groove 162 , and the plug-in board 161 can drive the spring piece 165 to contract when moving.

[0036] Furthermore, the follower 17 includes an L-shaped rod 171 on the baffle 154 , the top of the L-shaped rod 171 passes through the base 144 , and a concave opening 172 is formed on the L-shaped rod 171 , and the concave opening 172 is located above the plug board 161 .

[0037] When in use, when the baffle 154 is lifted or lowered, the L-shaped rod 171 can be driven to be lifted or lowered together, and one end of the spring piece 165 away from the plug board 161 is slidably connected to the side wall of the L-shaped rod 171 .

[0038] Furthermore, the guide member 18 includes an extrusion rod 181 inside the concave opening 172 . The number of the extrusion rods 181 is two, and the two extrusion rods 181 are symmetrically distributed. The wave groove 182 and the transverse groove 183 on the plug-in board 161 are interconnected, and the transverse groove 183 is located on a side adjacent to the first tooth groove 162 .

[0039] Specifically, the fixing block 166 is located between the spring piece 165 and the extrusion rod 181. Under normal circumstances, the spring piece 165 drives the plug-in board 161 to approach the semicircular ring 10. Due to the blocking of the extrusion rod 181 by the fixing block 166, the cut surface 163 on the plug-in board 161 is partially located inside the first tooth groove 162. When the extrusion rod 181 drops to the middle position of the wave groove 182, the plug-in board 161 can move laterally. At this time, the extrusion rod 181 can enter the inside of the transverse groove 183.

[0040] Furthermore, the adjustment mechanism can adjust the inclination angle of the lightning arrester according to the actual needs of the staff so that the lightning arrester is in the best use environment, including a fixing ring 20 on the sliding member 14, the fixing ring 20 is located at the top of the semicircular ring 10, the bottom of the fixing ring 20 is connected to a spring telescopic rod 21, the bottom of the spring telescopic rod 21 is connected to an extrusion portion 22, and a strip groove 23, a first slide groove 24 and a second slide groove 25 are provided on the locking member 15, the strip groove 23, the first slide groove 24 and the second slide groove 25 are all located on the rotating column 151, the strip groove 23 and the first slide groove 24 are interconnected, the strip groove 23 and the through-opening 152 are interconnected, the second slide groove 25 and the through-opening 152 are interconnected, the interior of the strip groove 23 is provided with a ejection portion 26, the interior of the second slide groove 25 is provided with a lifting portion 27, and the locking member 15 is provided with a limiting portion 28.

[0041] Furthermore, the extrusion part 22 includes an extrusion half ring 221 at the bottom of the spring telescopic rod 21, the curvature of the inner wall of the extrusion half ring 221 is adapted to the curvature of the outer wall of the semicircular ring 10, and the bottom of the extrusion half ring 221 is connected with an extrusion block 222, and the number of the extrusion blocks 222 is multiple, and the multiple extrusion blocks 222 are all arranged inside the first tooth groove 162.

[0042] When in use, under normal circumstances, the spring telescopic rod 21 drives the extrusion half ring 221 , and the extrusion half ring 221 drives the extrusion block 222 to be located at the highest point inside the first tooth groove 162 .

[0043] It should be noted that the extrusion block 222 does not contact the plug board 161 at this time.

[0044] Furthermore, the ejection portion 26 includes a semicircular plate 261 inside the strip groove 23, the semicircular plate 261 can move inside the first slide groove 24, a trapezoidal groove 262 is opened on the semicircular plate 261, the trapezoidal groove 262 is located on a side adjacent to the through-port 152, a threaded ring 263 is provided inside the through-port 152, a trapezoidal block 264 is provided on the side wall of the threaded ring 263, the trapezoidal block 264 is located inside the trapezoidal groove 262, and the height dimension of the trapezoidal block 264 is half of the height dimension of the trapezoidal groove 262.

[0045] It should be noted that the threaded ring 263 , the trapezoidal block 264 and the trapezoidal groove 262 are arranged so that the threaded ring 263 cannot rotate inside the through hole 152 .

[0046] When in use, when installing the arrester, the staff inserts the threaded end of the arrester into the through-hole 152, rotates the arrester so that the bottom of the arrester is threadedly connected to the threaded ring 263, and completes the installation of the arrester.

[0047] Furthermore, the lifting portion 27 includes a lifting block 271 inside the second slide groove 25, and the lifting block 271 is also located inside the through-hole 152. The lifting block 271 is located directly below the threaded ring 263. The lifting block 271 is located above the locking rod 153. A second spring 272 is provided at the top of the lifting block 271. One end of the second spring 272 away from the lifting block 271 is connected to the bottom of the threaded ring 263. The bottom of the lifting block 271 is provided with an arc surface 273, and the curvature of the arc surface 273 is adapted to the curvature of the outer wall of the rotating column 151.

[0048] When in use, when the lightning arrester rotates inside the threaded ring 263, as the lightning arrester descends, the bottom of the lightning arrester will squeeze the lifting block 271, causing the lifting block 271 to squeeze the locking rod 153, thereby causing the locking rod 153 to disengage from the inside of the through-hole 152, thereby releasing the restriction of the locking rod 153 on the rotating column 151.

[0049] Furthermore, the limiting part 28 includes a second tooth groove 281 on the outer wall of the rotating column 151, the second tooth groove 281 and the strip groove 23 are mutually connected, the second tooth groove 281 is located on the side away from the semicircular ring 10, and an insert block is provided on the top of the locking rod 153. It should be noted that when the semicircular plate 261 extends from the interior of the strip groove 23 , the semicircular plate 261 can close the second tooth groove 281 , thereby preventing the insert block from being inserted into the interior of the second tooth groove 281 .

[0050] Working principle: When it is necessary to install the lightning arrester, the staff first determines the number of lightning arresters. After the number of lightning arresters is determined, the staff holds the base 144, and the base 144 inserts the L-shaped clip 143 into the interior of the arc groove 141 through the notch 142. At this time, the plug-in board 161 located on the L-shaped clip 143 will contact the first tooth groove 162. Due to the setting of the cut surface 163 and the spring piece 165, when the base 144 drives the L-shaped clip 143 to move, the L-shaped clip 143 drives the plug-in board 161 to continuously squeeze the first tooth groove 162. The inner wall of the groove 162 causes the plug-in plate 161 to repeatedly reciprocate, and the plug-in plate 161 drives the spring piece 165 to repeatedly contract. When the position of the base 144 is determined, the staff inserts the lightning arrester into the inside of the through-hole 152. Due to the setting of the trapezoidal groove 262 and the trapezoidal block 264, when the bottom end of the lightning arrester is located at the threaded ring 263, the threaded ring 263 will not drop inside the through-hole 152 due to the weight of the lightning arrester. The staff can rotate the lightning arrester to install the lightning arrester on the base 144.

[0051] The staff can control the position of the lightning arrester inside the threaded ring 263. When the staff needs the lightning arrester to be perpendicular to the ground, they only need to rotate the lightning arrester so that the bottom end of the lightning arrester squeezes the lifting block 271 through the threaded ring 263, and the lifting block 271 drives the second spring 272 to extend. The lifting block 271 pushes the locking rod 153, so that the top of the locking rod 153 is separated from the inside of the through-hole 152. At the same time, when the locking rod 153 descends, it drives the baffle 154 to descend together, and the baffle 154 drives the first spring 155 to extend, and the baffle 154 drives the L-shaped The rod 171 descends together. When the L-shaped rod 171 drives the extrusion rod 181 inside the concave mouth 172 to descend, the extrusion rod 181 enters the interior of the wave groove 182. After being guided by the wave groove 182, when the extrusion rod 181 is located in the middle position of the wave groove 182, the spring piece 165 drives the plug-in board 161 to be further inserted into the interior of the first tooth groove 162. At this time, the position of the base 144 is defined, and the extrusion rod 181 and the horizontal groove 183 are at the same height, so as to avoid the position of the base 144 from being offset when the tilt angle of the lightning arrester is adjusted later.

[0052] When it is necessary to adjust the tilt angle of the lightning arrester, since the bottom of the lightning arrester has disengaged the locking rod 153 and the plug block from the inside of the through-hole 152, at this time, due to the setting of the coil spring, the lightning arrester still maintains a vertical state, and the staff can directly pull the lightning arrester. When the lightning arrester rotates, it can drive the rotating column 151 to rotate. When the second tooth groove 281 moves to the plug block, the first spring 155 recovers and can drive the baffle 154 to rise, and the baffle 154 drives the locking rod 153. The locking rod 153 enters the inside of the second tooth groove 281 with the plug block to complete the locking. When the staff needs to continue to adjust the tilt angle of the lightning arrester, the staff only needs to pull the lightning arrester upwards, and the lightning arrester can drive the threaded ring 263 to drive the trapezoidal block 264 rises, the trapezoidal block 264 squeezes the trapezoidal groove 262, so that the semicircular plate 261 extends out from the inside of the strip groove 23, and the semicircular plate 261 pushes the plug out from the inside of the second tooth groove 281. At this time, the staff pushes the lightning arrester downward to make the lightning arrester flip over. When the lightning arrester reaches the specified inclined position, the pulling force on the lightning arrester is removed. At this time, the second spring 272 recovers and drives the threaded ring 263 to descend, and the threaded ring 263 drives the trapezoidal block 264 to the bottom of the trapezoidal groove 262. At this time, the semicircular plate 261 is retracted into the inside of the strip groove 23, and the first spring 155 recovers and drives the locking rod 153, and the locking rod 153 drives the plug into the inside of the second slot to complete the fixation of the inclined lightning arrester.

[0053] When the lightning arrester is tilted, it is inconvenient for the staff to rotate the lightning arrester body. When the lightning arrester is perpendicular to the ground, it is more convenient to rotate the lightning arrester body. In order to facilitate the staff to disassemble and replace the lightning arrester, when the staff needs to disassemble and replace the lightning arrester, the staff can manually pull the baffle 154 to make the baffle 154 downward, the baffle 154 drives the first spring 155 to contract, the baffle 154 drives the locking rod 153 to descend, and the locking rod 153 drives the plug to disengage from the inside of the second tooth groove 281. At this time, the coil spring recovers and drives the lightning arrester to return to a vertical state. The staff removes the pulling force of the baffle 154 and continues to rotate the lightning arrester to complete the disassembly of the lightning arrester.

[0054] When the staff needs to change the number of lightning arresters on the semicircular ring 10, in order to improve the staff's work efficiency, the staff drives the extrusion semi-ring 221 downward to extend the spring telescopic rod 21, and the two extrusion semi-rings 221 drive the extrusion block 222 to descend and squeeze the inclined surface 164 on the plug-in board 161, so that the extrusion rod 181 enters the interior of the transverse groove 183, and the spring piece 165 restores and drives the plug-in board 161 to move, so that the plug-in board 161 is restored to the part where the section 163 is located inside the first tooth groove 162. At this time, the staff can directly move the position of the base 144 and remove the base 144 from the semicircular ring 10, avoiding the tedious process of the staff rotating multiple lightning arresters.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
