[0005] Because the heights of the lines and the fixing seats are different, insulators of different heights are often required. However, the heights of insulators and insulator fittings are fixed, and different specifications are often required, which increases the cost of design and production and causes a waste of resources. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that due to the different heights between the line and the fixing seat, insulators of different heights are often required, while the heights of the insulators and insulator fittings are fixed, and different specifications are often required, which increases the cost of design and production and causes a waste of resources.

[0007] In order to solve the above problems, the utility model provides an insulator hardware with adjustable distance, including a hardware body, a connecting rod fixedly connected to the bottom end of the hardware body, a threaded sliding rod slidably connected to the bottom end of the connecting rod, a sliding groove symmetrically cut out of the inner wall of the connecting rod, a sliding block corresponding to the sliding groove fixedly connected at the top position of the side wall of the threaded sliding rod, and the sliding block is slidably connected to the sliding groove, a nut is sleeved on the threaded sliding rod, and the shape of the inner wall of the nut matches and engages with the surface of the connecting rod and the threaded sliding rod, a first baffle is fixedly connected to the bottom end of the threaded sliding rod, an inwardly recessed threaded groove is opened at the bottom of the threaded sliding rod, and the threaded groove is threadably connected to the insulator, a protective cover is detachably connected to the top of the side wall of the connecting rod, a rubber ring is fixedly connected to the bottom end of the protective cover, and the rubber ring is sleeved outside the first baffle and engages with the bottom of the first baffle.

[0008] In the above-mentioned insulator hardware, the distance between the hardware body and the insulator can be freely adjusted effectively, thereby adapting to the distance between different lines and the fixing seat.

[0009] As a further improvement of the present application, the top end of the protective cover is threadedly connected to the surface of the connecting rod, and a sealing ring is installed between the hardware body and the connecting rod.

[0010] As a further improvement of the present application, a second blocking piece is sleeved on the outer wall of the connection end, and an annular groove with the same diameter as the threaded sliding rod is formed between the second blocking piece and the insulator.

[0011] As a further improvement of the present application, two clamps are detachably connected to the connecting end, and the two clamps are clamped between the connecting end and the surface of the annular groove.

[0012] As another improvement of the present application, two clamps are symmetrically fixedly connected with connecting blocks at one end close to each other, and the two connecting blocks are fixed by bolts.

[0013] As another improved supplement of the present application, the inner wall of the clamp is provided with a groove, and the radius of the groove is larger than the radius of the first baffle and the insulator.

[0014] As another improved supplement of the present application, the rubber ring is elastically designed and is sleeved in the annular groove.

[0015] In summary, the present scheme can be designed that when installing the insulator, the protective cover is firstly fixed with the outer surface of the connecting rod by thread. The threaded connection method is convenient for replacing the protective cover. Then the connecting end is inserted into the thread groove and screwed so that the threaded slide rod is fixed with the insulator thread. Then, the distance of the threaded slide rod is adjusted according to the distance between the line and the fixing seat, so that the threaded slide rod can slide up and down in the connecting rod through the slider to adjust the height. After adjusting to the appropriate height, the nut is put on the connection between the threaded slide rod and the connecting rod, and the nut is fixed with the connecting rod and the threaded slide rod by screwing. The surface of the rod is fixed with threads, thereby positioning the threaded sliding rod. At this time, the protective cover made of elastic and foldable material is pulled downward to enlarge the rubber ring so that its diameter is larger than the first baffle and reaches the bottom of the first baffle. Then it is loosened to restore the diameter and limit the position with the first baffle, so that the protective cover is unfolded and covers the outer surface of the connecting rod and the threaded sliding rod to prevent the nut from being soaked by rainwater and causing corrosion and rust, which makes it difficult to disassemble and assemble. The distance between the hardware body and the insulator can be freely adjusted effectively, thereby adapting to the distance between different lines and the fixing seat.

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] Figure 1-6 The invention discloses an insulator fitting with adjustable distance, comprising a fitting body 1, a connecting rod 2 is fixedly connected to the bottom end of the fitting body 1, a threaded sliding rod 3 is slidably connected to the bottom end of the connecting rod 2, a sliding groove 10 is symmetrically opened on the inner wall of the connecting rod 2, a sliding block 9 corresponding to the sliding groove 10 is fixedly connected at the top position of the side wall of the threaded sliding rod 3, and the sliding block 9 is slidably connected to the sliding groove 10, a nut 8 is sleeved on the threaded sliding rod 3, and the inner wall shape of the nut 8 matches and engages with the surface of the connecting rod 2 and the threaded sliding rod 3, a first baffle 4 is fixedly connected to the bottom end of the threaded sliding rod 3, an inwardly sunken thread groove 11 is opened at the bottom of the threaded sliding rod 3, and the threaded groove 11 is threadedly connected to an insulator 6 through a connecting end 5, a protective cover 7 is detachably connected to the top of the side wall of the connecting rod 2, a rubber ring 13 is fixedly connected to the bottom end of the protective cover 7, and the rubber ring 13 is sleeved on the outside of the first baffle 4 and engages with the bottom thereof, the top end of the protective cover 7 is threadedly connected to the surface of the connecting rod 2, and a sealing ring 12 is installed between the fitting body 1 and the connecting rod 2.

[0029] This solution can be designed. When installing the insulator 6, the protective cover 7 is first fixed with the outer surface of the connecting rod 2 by thread. The threaded connection method is convenient for replacing the protective cover 7. Then the connecting end 5 is inserted into the thread groove 11 and screwed, so that the threaded slide rod 3 and the insulator 6 are threaded and fixed. Then, according to the distance between the line and the fixed seat, the distance of the threaded slide rod 3 is adjusted, so that the threaded slide rod 3 slides up and down in the connecting rod 2 through the slider 9 to adjust the height. After adjusting to the appropriate height, the nut 8 is put on the connection between the threaded slide rod 3 and the connecting rod 2, and the nut 8 is screwed to the connecting rod 2 and the threaded slide rod. 3 is fixed by threading, thereby positioning the threaded slide rod 3. At this time, the protective cover 7 made of elastic and foldable material is pulled downward to enlarge the rubber ring 13 so that its diameter is larger than the first baffle 4 and reaches the bottom of the first baffle 4. Then, it is loosened to restore the diameter of 13 and limit the position with the first baffle 4, so that the protective cover 7 is unfolded and covers the outer surface of the connecting rod 2 and the threaded slide rod 3, avoiding corrosion and rust caused by the nut 8 being soaked by rainwater, and being difficult to disassemble and assemble, thereby effectively achieving the effect of freely adjusting the distance between the hardware body 1 and the insulator 6, thereby adapting to the distance between different lines and the fixing seat.

[0030] The second implementation method:

[0031] Figure 1-2 and Figure 7-8 It is shown that the outer wall of the connecting end 5 is sleeved with a second baffle 14, and an annular groove with the same diameter as the threaded sliding rod 3 is formed between the second baffle 14 and the insulator 6. Two clamps 15 are detachably connected to the connecting end 5, and the two clamps 15 are clamped on the connecting end 5 and the surface of the annular groove. The two clamps 15 are symmetrically fixedly connected with connecting blocks 16 at one end close to each other, and the two connecting blocks 16 are fixed by bolts. The inner walls of the clamps 15 are provided with grooves, and the radius of the grooves is larger than the radius of the first baffle 4 and the insulator 6. The rubber ring 13 is designed to be elastic, and the rubber ring 13 is sleeved in the annular groove.

[0032] The present invention can realize that whenever the hardware body 1 and the insulator 6 are assembled, the two clamps 15 can be clamped at the connection between the threaded slide rod 3 and the insulator 6 after the connection end 5 is threadedly fixed with the threaded slide rod 3, so that the groove on the inner wall of the clamp 15 conflicts with the second baffle 14 and the first baffle 4, and the upper and lower parts of the side ends of the clamp 15 are respectively engaged with the threaded slide rod 3 and the annular groove. At this time, the connecting block 16 is fixed by bolts to position the two clamps 15, so as to lock the threaded slide rod 3 and the insulator 6, so as to prevent the insulator 6 and the hardware body 1 from being loosened at the connection end 5 and the threaded groove 11 when they are at high altitude and shaken by strong wind, thereby causing an accident and causing the insulator 6 to fall off and cause a dangerous effect. After installation, the rubber ring 13 can be pulled and put on the second baffle 14, so that the protective cover 7 covers the clamp 15 to prevent it from being difficult to disassemble and assemble after rusting.

[0033] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
