The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Example one

As shown in fig. 1, the embodiment provides a porcelain cross arm, which includes a porcelain cross arm body 1, and a wire fixing assembly and a tower connecting assembly respectively disposed at two ends of the porcelain cross arm body 1, wherein the wire fixing assembly includes a retaining ring 22 provided with an opening and a moving member 23, the moving member 23 is swingably disposed at the opening to avoid a wire from entering the retaining ring 22 from the opening or to block the opening so as to fix the wire in the retaining ring 22; the tower connecting assembly comprises a locking ring 31 with adjustable inner diameter, and the locking ring 31 can be sleeved outside the tower.

During installation, the movable part 23 is rotated to enable the wire to penetrate through the opening in the retaining ring 22, the movable part 23 is rotated in the opposite direction to seal the opening to fix the wire, the wire is sleeved on the tower through the locking ring 31, the inner diameter of the wire is adjusted to prevent the locking ring 31 from sliding along the axial direction of the tower, and therefore the connection between the porcelain cross arm and the wire and the tower is completed; during the removal, only the inner diameter of the locking ring 31 and the rotating movable piece 23 need to be adjusted respectively. The porcelain cross arm is simple in structure and convenient to use, and the mounting stability is guaranteed while the dismounting efficiency is improved.

In addition, the frequency of removing the lead is higher, so that the snap ring 22 is sleeved outside the lead directly through the opening and the opening is blocked by the movable piece 23, which is more convenient, and the efficiency of removing and installing can be improved.

In addition, the locking ring 31 capable of adjusting the inner diameter and the retaining ring 22 capable of directly covering and buckling the outside of the wire can respectively adapt to towers and wires with different diameters.

Specifically, the subassembly is fixed to the wire still includes the elastic component, and the both ends of elastic component are connected with moving part 23 and porcelain cross arm body 1 respectively, and moving part 23 can the shutoff opening when the elastic component is in free length. When the lead is required to be fixed, the lead pushes the movable piece 23 to rotate from the opening to enter the retaining ring 22, at the moment, the movable piece 23 is stretched and deformed due to external force, when the lead completely enters the retaining ring 22, the movable piece 23 is separated from the lead, and at the moment, the lead is driven to rotate in the opposite direction to block the opening due to the resilience force of the elastic piece when the lead is not subjected to the external force.

Illustratively, the resilient member is a spring.

In this embodiment, considering that the porcelain cross arm body 1 is a ceramic material, the wire fixing component further includes a base 21, the base 21 is fixed on one end of the porcelain cross arm body 1, the retaining ring 22 is fixed on the base 21, one end of the movable member 23 is rotatably connected to the base 21 through the elastic member, that is, the base 21 is connected to the porcelain cross arm body 1, so that the retaining ring 22 and the elastic member can be installed more conveniently, and the installation stability can be ensured.

Further, the porcelain cross arm further comprises a wire falling-off prevention piece 4, one end of the wire falling-off prevention piece 4 is rotatably arranged on the base 21, and the other end of the wire falling-off prevention piece 4 can be abutted against the outer wall of the retaining ring 22 to form a closed space with the retaining ring 22. That is, after the lead fixing component is used for a long time, the elastic piece loses part of the elasticity to cause that the opening can not be blocked, and the lead is further fixed through the lead anti-falling piece 4. When one end of the wire anti-falling part 4 abuts against the outer wall, the wire anti-falling part is detachably fixed to the retaining ring 22 by a fastener in this embodiment, however, in other embodiments, other structures may be adopted to detachably connect the wire anti-falling part 4 to the retaining ring 22, and this embodiment is not limited in particular.

In this embodiment, the locking ring 31 is made of an elastic band, the tower connection assembly further includes a lock catch 32, the elastic band forms the locking ring 31 through the lock catch 32, and the inner diameter of the locking ring 31 formed by the elastic band can be adjusted through the lock catch 32, the inner diameter of the locking ring 31 formed when the elastic band is connected end to end is the largest, wherein, as the adjustment of the inner diameter of the locking ring 31 through the lock catch 32 is common knowledge in the art, the embodiment is not specifically described. Of course, considering the material of the elastic band, in other embodiments, the locking ring 31 may also be a hose clamp, and since it is common knowledge in the art to adjust the inner diameter of the hose clamp, the embodiment will not be described in detail.

Considering that birds sometimes rest on the porcelain cross arm and even nest to cause corresponding tripping of a power distribution network line, the porcelain cross arm further comprises a bird repelling component, the bird repelling component comprises a connected ultrasonic device and a plurality of solar panels 51, and the plurality of solar panels 51 are annularly arranged on the outer wall of the locking ring 31, namely, the solar panels 51 provide electric energy for the ultrasonic device to enable the ultrasonic device to continuously emit bird repelling sound waves. In addition, the solar panels 51 are annularly arranged on the outer wall of the locking ring 31, so that the absorbed solar energy can be increased as much as possible.

Wherein, the porcelain cross arm still includes that a plurality of intervals set up the reinforcement 11 on porcelain cross arm body 1, and the both ends of reinforcement 11 all bulge in porcelain cross arm body 1 in order to prevent the insulation breakdown that electrified body electric arc creepage leads to.

Further, the reinforcement 11 and the porcelain cross arm body 1 are of an integrally formed structure.

Example two

The embodiment provides a porcelain cross arm, which further improves the stability of the porcelain cross arm connected with a wire and a tower respectively on the basis of the first embodiment.

Specifically, the first anti-slip layer is laid on the inner wall of the retaining ring 22 to prevent the retaining ring 22 from sliding along the axial direction of the wire, so that the stability of connection between the porcelain cross arm and the tower is affected. Similarly, the inner wall of the movable member 23 may also be laid with a first anti-slip layer, and this embodiment is not particularly limited.

Further, the inner wall of the lock ring 31 is paved with a second anti-slip layer to avoid the lock ring 31 from slipping along the axial line of the tower, and further influence the stability of the connection between the porcelain cross arm and the wire.

Exemplarily, the first anti-slip layer and the second anti-slip layer are both made of rubber materials, so that not only can the friction force of contact be improved, but also the damage to the wires and the outer wall of the tower during disassembly and assembly can be avoided due to the fact that the rubber materials have certain elastic energy.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
