Description

It is an indispensable basic component in power distribution network.

[0003] In the early stage of power application, the line erection is relatively simple, and the wires are often fixed directly on the top or side of the pole, lacking a special support structure.

The adjusting mechanism 2 comprises a rotating shaft 21, the rotating shaft 21 is rotationally connected to the middle part of the bottom end of the support plate 5, the bottom of the rotating shaft 21 is rotationally connected with the base 1, the support plate 5 is connected with the base 1 through the rotating shaft 21, the top of the base 1 is provided with movable plates 22 on the left side and the right side, the distal ends of the two movable plates 22 are fixedly connected with gear clamps 23, the top of the base 1 is rotationally connected with flat gears 24 on the left end and the right end, the two gear clamps 23 are respectively meshed with the corresponding flat gears 24, the flat gears 24 can be fixed through the gear clamps 23, the bottom of the support plate 5 is fixedly connected with arc-shaped racks 25 on the left end and the right end, the two arc-shaped racks 25 are respectively meshed with the corresponding flat gears 24, when the flat gears 24 are meshed with the gear clamps 23, the position of the arc-shaped racks 25 can be fixed, the inner side of the base 1 is provided with a control assembly 26, the control assembly 26 comprises a bidirectional threaded rod 261, the bidirectional threaded rod 261 is rotationally connected to the middle part of the inner side of the base 1, the outer wall of the bidirectional threaded rod 261 is threadedly connected with sliding blocks 262 on the left side and the right side, when the bidirectional threaded rod 261 rotates, the sliding blocks 262 will move, the adjacent sides of the two movable plates 22 are respectively penetrated through the base 1 and fixedly connected with the corresponding sliding blocks 262, the sliding blocks 262 will drive the movable plates 22 to move, the right end of the bidirectional threaded rod 261 penetrates through the base 1, the control assembly 26 further comprises a knob 263, the knob 263 is fixedly connected to the right end of the bidirectional threaded rod 261, the knob 263 facilitates the rotation of the bidirectional threaded rod 261 by the staff, the size of the inner side of the base 1 is matched with the size of the sliding blocks 262; Specifically, when the cross arm needs to be adjusted in orientation after installation, the knob 263 is rotated, which drives the bidirectional threaded rod 261 to rotate. With the rotation of the bidirectional threaded rod 261, the sliding block 262 also moves. In the movement of the sliding block 262, the movable plate 22 drives the gear block 23 to move synchronously. When the gear block 23 moves, it is disengaged from the meshing state with the flat gear 24, thereby releasing the limiting constraint on the flat gear 24. At this time, the support plate 5 is rotated, which drives the arc-shaped rack 25 connected thereto to move. Since the flat gear 24 and the arc-shaped rack 25 are in meshing relationship, when the arc-shaped rack 25 moves, it drives the flat gear 24 to rotate. The rotation of the support plate 5 can realize the adjustment of the orientation of the cross arm.

[0023] With reference to Figure 2 , Figure 5 and Figure 6 , the protection mechanism 3 comprises two supports 31 fixedly connected to the left and right sides of the rear wall of the base 1. The inner side of the support 31 is fixedly connected with a fixed rod 32. The outer side of the fixed rod 32 is provided with a first spring 33. The outer wall of the fixed rod 32 is slidingly connected with an L-shaped plate 34. One end of the L-shaped plate 34 is fixedly connected with a connecting seat 35. The L-shaped plate 34 is pressed when it moves. The connecting seat 35 is fixedly connected with a protection plate 36 on one side. The protection plate 36 can be attached to the cement single pole. The bottom of the support 31 is provided with a damping assembly 37. The rear middle part of the base 1 is provided with a fixing assembly 38. The damping assembly 37 comprises a hollow plate 371 rotatably connected to the bottom end of the support 31. The inner side top of the hollow plate 371 is fixedly connected with a guide rod 372. The outer side of the guide rod 372 is provided with a second spring 373. The outer side bottom of the guide rod 372 is slidingly connected with a movable rod 374. The movable rod 374 is pressed when it moves. The bottom of the movable rod 374 is rotatably connected with the protection plate 36. The movement of the protection plate 36 drives the movement of the movable rod 374; Specifically, when installing the device, the protective plate 36 is sleeved on the outside of the cement single pole, the first spring 33 pushes the L-shaped plate 34 to move, and the L-shaped plate 34 further pushes the protective plate 36 to move through the connecting seat 35 during the movement, so that the protective plate 36 is attached to the surface of the cement single pole, thereby realizing the pre-fixing of the cross arm and facilitating the installation of the device by the staff. When the wires on the cross arm are affected by severe weather conditions and produce violent shaking, the shaking will be transmitted to the cross arm, causing the cross arm to also swing. During the swinging of the cross arm, the relative position between the cross arm and the protective plate 36 changes, and at this time the protective plate 36 pushes the L-shaped plate 34 and the movable rod 374 to move. During the movement of the L-shaped plate 34 and the movable rod 374, pressure is applied to the first spring 33 and the second spring 373, respectively. After being extruded, the first spring 33 and the second spring 373 shrink and absorb the force generated when the cross arm swings, which can effectively reduce the swinging amplitude of the cross arm, thereby ensuring that the entire device remains stable under severe weather conditions and is not damaged due to external environmental influences, improving the practicality of the device.

[0024] With reference to Figure 7 , Figure 8 and Figure 9 , the telescopic mechanism 4 includes two auxiliary plates 41, which are respectively connected to the inside left and right sides of the support plate 5 in a sliding manner. A plurality of clamping grooves 42 are equidistantly formed on the inside front and back sides of the auxiliary plate 41. A clamping block 43 is arranged on the inside left and right ends of the support plate 5. The plurality of clamping blocks 43 are respectively clamped with the corresponding clamping grooves 42. The clamping block 43 and the clamping groove 42 are clamped to fix the position of the auxiliary plate 41. The support plate 5 is fixedly connected with a support rod 44 on the inside left and right ends. The outer walls of the two support rods 44 are respectively connected with the corresponding clamping blocks 43 in a sliding manner. The clamping block 43 can slide on the outside of the support rod 44. A third spring 45 is arranged on the outside middle part of the two support rods 44. A pressing assembly 46 is arranged on one side of the plurality of clamping blocks 43. The pressing assembly 46 includes a plurality of push rods 461, which are respectively fixedly connected on one side of the corresponding clamping blocks 43. One end of the plurality of push rods 461 penetrates the support plate 5 and is fixedly connected with a rubber ball 462. The rubber ball 462 can drive the clamping block 43 to move through the push rod 461. The telescopic mechanism 4 further includes a plurality of insulators 47, which are equidistantly fixedly connected on the top of the support plate 5. A plurality of screw holes 48 are equidistantly formed on the top of the two auxiliary plates 41. The screw holes 48 can be used to install the insulators 47. Specifically, when fixing multiple lines using the device, the rubber balls 462 on both sides are pressed, and the rubber balls 462 drive the clamping blocks 43 on both sides to move synchronously to the middle. With the movement of the clamping blocks 43, the clamping blocks 43 are separated from the clamping grooves 42, thereby releasing the limiting effect on the auxiliary plate 41. At this time, the auxiliary plate 41 is pulled out from the inside of the support plate 5 and passes through the screw holes 48 at the top of the support plate 5. The insulator 47 can be installed on the top of the support plate 5. Not only more lines can be installed on the cross arm, but also the width of the cross arm can be adjusted according to the specific needs of the actual installed lines, thereby improving the convenience of the device.

[0025] With reference to Figure 1 , Figure 2 and Figure 5 , the fixing assembly 38 includes a hoop 381 arranged at the middle of the rear side of the base 1. The front side of the hoop 381 is threaded and connected with nuts 382 on both sides of the base 1. By tightening the nuts 382, the size of the inside of the hoop 381 can be controlled. Specifically, when fixing the cross arm, the nuts 382 are rotated to tighten the hoop 381, thereby conveniently fixing the cross arm with the cement single pole.

[0026] With reference to Figure 1 , Figure 5 and Figure 6 , the protection mechanism 3 further includes a fixing frame 39 fixedly connected to the middle of the rear wall of the base 1. Adjacent sides of the two protection plates 36 are fixedly connected with anti-skid pieces 310, which can prevent the protection plates 36 from sliding. Specifically, the fixing frame 39 can improve the stability of the fixed cross arm, and the anti-skid pieces 310 can prevent the protection plates 36 from sliding.

[0027] Working principle: when the orientation of the cross arm needs to be adjusted after the cross arm is installed, the knob 263 is rotated to rotate the bidirectional threaded rod 261, thereby driving the sliding block 262 to move. When the sliding block 262 moves, the movable plate 22 can drive the gear block 23 to move. When the gear block 23 moves, it is disengaged from the meshing state with the flat gear 24, thereby releasing the limiting of the flat gear 24. At this time, the support plate 5 is rotated to drive the arc-shaped rack 25 to move. Since the flat gear 24 is meshed with the arc-shaped rack 25, the arc-shaped rack 25 moves to drive the flat gear 24 to rotate. By rotating the support plate 5, the orientation of the cross arm can be adjusted. When the adjustment is completed, the bidirectional threaded rod 261 is reversely rotated, and the sliding block 262 drives the gear block 23 to move through the movable plate 22, so that the gear block 23 is meshed with the flat gear 24, thereby fixing the orientation of the support plate 5. And when installing the device, by sleeving the protective plate 36 outside the cement single rod, the first spring 33 will push the L-shaped plate 34 to move, the L-shaped plate 34 pushes the protective plate 36 to be attached to the cement single rod through the connecting seat 35, so that the device can be pre-fixed, which is convenient for the staff to install the device, and when the wires on the cross arm are affected by bad weather and shake, the cross arm will swing, the relative position of the cross arm and the protective plate 36 will change, at this time the protective plate 36 will push the L-shaped plate 34 and the movable rod 374 to move, the L-shaped plate 34 and the movable rod 374 will squeeze the first spring 33 and the second spring 373 respectively when moving, the first spring 33 and the second spring 373 will shrink and absorb the force when the cross arm swings, so as to reduce the swing of the cross arm, so that the device will not be damaged due to bad weather; Finally, when fixing multiple lines by using the device, press the rubber balls 462 on both sides to make the rubber balls 462 on both sides move to the middle, and through the pull rod 461, the two clamping blocks 43 can be driven to move to the middle at the same time, so that the clamping blocks 43 on both sides are separated from the clamping grooves 42, thereby releasing the limiting of the auxiliary plate 41, at this time, pull the auxiliary plate 41 to make the auxiliary plate 41 extend out of the supporting plate 5, and through the screw holes 48 on the top of the supporting plate 5, install the insulator 47, so as to install more lines on the cross arm, and the cross arm can be adjusted according to the needs of installing lines.
