[0003] When the above technology is in use, a certain degree of base adjustment effect is achieved through the worm gear structure. However, in actual use, due to the constraints of the overall structure of the device, the base adjustment distance is short and the base cannot be adjusted individually in a targeted manner, resulting in low practicality in actual use. Therefore, in order to solve the above technical defects, we propose a lightning arrester with an adjustable base. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-4 A lightning arrester with an adjustable base comprises a base 1 and a lightning arrester body 6, wherein mounting seats 2 are slidably provided at both ends of the upper side of the base 1, and the lightning arrester body 6 is installed on the upper surface of the mounting seat 2, and left-handed threaded rods 3 are provided at both ends inside the base 1, and the ends of the left-handed threaded rods 3 that are away from each other extend to the outside of the base 1, and the lower end of the mounting seat 2 is connected to the adjacent left-handed threaded rods 3, and the ends of the left-handed threaded rods 3 that are close to each other are jointly provided with a plurality of slots 4, and a clutch cylinder 5 is slidably sleeved through the slot 4 at the end of one of the left-handed threaded rods 3, and locking bolts 7 are provided at the ends of both ends of the base 1, and the lower ends of the locking bolts 7 face the adjacent left-handed threaded rods 3.

[0024] Example 2

[0025] Reference Figure 1-4 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0026] The locking bolt 7 is provided with a top spring 8 at one end of the base 1, and a locking block 9 is provided at the lower end of the top spring 8. The lower end of the locking block 9 abuts against the outer ring surface of the rod body of the left and right rotating threaded rod 3. A force rod 10 is installed at one end of the locking bolt 7 located outside the base 1. The contact surface of the locking block 9 and the left and right rotating threaded rod 3 is provided with anti-slip grooves. The arrangement of the top spring 8 and the locking block 9 makes the locking bolt 7 have a better fixing effect on the left and right rotating threaded rod 3 when tightened, which can effectively prevent the left and right rotating threaded rod 3 from rotating by itself when the personnel do not actively apply force. The arrangement of the force rod 10 makes it more labor-saving for the personnel to rotate the locking bolt 7; the left and right rotating threaded rods 3 are both provided with jacks inside the ends close to each other, and a support rod 11 is inserted in the jack. The arrangement of the support rod 11 makes it possible to connect the ends of the left and right rotating threaded rods 3 close to each other, that is, both ends of the left and right rotating threaded rods 3 can be supported, thereby effectively improving the stability of the left and right rotating threaded rods 3.

[0027] There are levers 12 on both sides of the clutch cylinder 5, and matching travel grooves are provided on both sides of the base 1 corresponding to the levers 12. The setting of the levers 12 makes it more convenient for personnel to operate the clutch cylinder 5; the outer ring surface of the left-handed and right-handed threaded rods 3 is installed with a matching magnetic ring 13 corresponding to the clutch cylinder 5, and the outer ring surface of the magnetic ring 13 is attached to the inner wall of the clutch cylinder 5. The setting of the magnetic ring 13 ensures a certain degree of stability between the clutch cylinder 5 and the left-handed and right-handed threaded rods 3, that is, the clutch cylinder 5 will not move by itself when personnel do not actively apply force; there are a number of threaded holes on both sides of the base 1, and the threaded holes are aligned with the side surfaces of the mounting seat 2. The setting of the threaded holes makes it convenient for personnel to install fixing bolts, thereby fixing the two sides of the upper end of the mounting seat 2 by fixing bolts, so as to further enhance the stability of the lightning arrester body 6 after installation.

[0028] Principle and advantages of use: During the use of the utility model, the base 1 is installed in the outside world, and the lightning arrester body 6 is installed on two mounting seats 2. Then, when the lightning arrester body 6 needs to adjust the spacing due to the external installation environment, if synchronous adjustment is required, the personnel will toggle the clutch cylinder 5 to move the clutch cylinder 5 to either end until the clutch cylinder 5 is separated from the slot 4 at the end of the other left-handed threaded rod 3. At this time, there are no other connecting parts between the two clutch cylinders 5 except the support rod 11 that is only rotatably connected. That is, at this time, the personnel can rotate the two left-handed threaded rods 3 separately, thereby driving the lightning arrester body 6 to move accordingly when the left-handed threaded rods 3 rotate, thereby adjusting the spacing of a single lightning arrester body 6 accordingly.

[0029] Furthermore, in the above process, when it is necessary to synchronously adjust the spacing of the lightning arrester body 6, the personnel reversely toggle the clutch cylinder 5 so that the two ends of the clutch cylinder 5 are respectively combined with the slots 4 of the two left-handed threaded rods 3, so that under the action of the slots 4, the two left-handed threaded rods 3 can only rotate synchronously, thereby driving the lightning arrester body 6 to move closer or farther synchronously; in summary, this scheme uses the left-handed threaded rods 3 to drive the mounting seat 2 to move, compared with the traditional method of driving the lightning arrester to move through a crank rocker arm structure. When using the traditional scheme, in order to extend the moving range of the lightning arrester, it is necessary not only to lengthen the device, but also to significantly lengthen the width of the device, thereby significantly reducing the overall width of the device compared with the traditional scheme, that is, reducing the volume of the device, which is more convenient for people to carry and transport.

[0030] It should be further explained that the setting of the top spring 8 and the locking block 9 makes the locking bolt 7 have a better fixing effect on the left-hand and right-hand threaded rod 3 when tightening, which can effectively prevent the left-hand and right-hand threaded rod 3 from rotating by itself when personnel do not actively apply force. The setting of the force rod 10 makes it easier for personnel to turn the locking bolt 7; the setting of the support rod 11 makes it possible for the ends of the left-hand and right-hand threaded rods 3 that are close to each other to be connected to each other, so that both ends of the left-hand and right-hand threaded rods 3 can be supported, thereby effectively improving the stability of the left-hand and right-hand threaded rods 3. The setting of the shift rod 12 makes it more convenient for personnel to operate the clutch cylinder 5; the setting of the magnetic ring 13 maintains a certain degree of stability between the clutch cylinder 5 and the left-hand and right-hand threaded rod 3, that is, the clutch cylinder 5 will not move by itself when personnel do not actively apply force; the setting of the bottom threaded hole is convenient for further strengthening the stability of the lightning arrester body 6 after installation.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
