Description

Technical Field

[0001] The present application relates to the technical field of cable tensioners, and in particular to a tail end cable tensioner. Background Art

[0002] As a necessary connector in the installation of high (low) voltage overhead lines, the tensioner plays an indispensable role in fixing the power supply cables. Its convenience, reliability and durability greatly reduce the difficulty of laying cables, providing strong support for the process of urbanization development.

[0003] In the prior art, the one-stop tail end tensioner used for the tail end of the cable includes a male pressure block, a female pressure block and a protective cover. During use, the male pressure block and the female pressure block are matched and connected together, and then tightened by a locking bolt, and finally a protective cover is set to hide the metal parts. However, during use, the male pressure block and the female pressure block of the tensioner must be completely disassembled before they can be sleeved on the outer periphery of the cable, which is inconvenient to operate. At high altitudes, they may fall out of the hands and cause the dangerous situation of falling objects from high altitudes. Therefore, there is room for improvement. Summary of the Invention

[0004] In response to the above problems, the present application proposes a tail end tensioner. By extending the threaded pin on the male pressure block, the female pressure block can be sleeved onto the cable to be tightened without the outer ring of the female pressure block being separated from the male pressure block, so that the male pressure block and the female pressure block are always kept as a whole, achieving the advantage of no need for complete disassembly in terms of operation, and achieving the beneficial effect of reducing the risk of falling objects from heights. The tail end tensioner is specifically implemented through the following technical solutions:

[0005] A tail end tensioner comprises: a male pressure block, a female pressure block and a protective cover, the male pressure block is provided with a threaded pin, the female pressure block is provided with a socket corresponding to the threaded pin, the male pressure block and the female pressure block are plugged together, and a locking screw sleeve is provided on the threaded pin to achieve detachable fastening, the protective cover is provided on the female pressure block, the threaded pin is provided with two, and is respectively provided as a first threaded pin and a second threaded pin, and the length of the second threaded pin is greater than that of the first threaded pin.

[0006] It is further configured that during the process of connecting the second threaded pin with the male pressure block along the direction of the insertion hole, when the second threaded pin completely penetrates the insertion hole, the first threaded pin does not interfere with the insertion hole, and the female pressure block can rotate freely with the second threaded pin as the axis. Through this configuration, the female pressure block can be separated from the first threaded pin without being separated from the second threaded pin, thereby realizing the separation of the male pressure block and the female pressure block, which is convenient for installation on the cable.

[0007] It is further provided that after the second threaded pin passes through the insertion hole, a limiting top block is provided at the end of the second threaded pin. Through this setting, the female pressure block is prevented from completely falling out of the second threaded pin, thereby reducing the installation steps and the risk of parts falling.

[0008] It is further provided that the limiting top block is fixedly connected to the second threaded pin by welding. Through this provision, the anti-slip strength is improved and the overall structure is more stable.

[0009] It is further provided that the male pressure block and the female pressure block are respectively provided with a first opening groove and a second opening groove, and the first opening groove and the second opening groove are provided as semicircular openings facing each other. Through this setting, the first opening groove and the second opening groove are fitted together to form an annular locking part, and as the tightness of the male pressure block and the female pressure block changes, the compression of the cable can be adjusted.

[0010] It is further provided that the inner walls of the first opening groove and the second opening groove are both provided with anti-slip protrusions, and the anti-slip protrusions extend along the extension direction of the cable and extend along the circumference of the first opening groove and the second opening groove. Through this setting, the friction force is increased, the cable is prevented from sliding, and the overall stability of the body is more improved.

[0011] It is further provided that a limiting ring groove is provided on the mother pressure block. When the protective cover is sleeved on the outer end of the mother pressure block, the outer edge of the protective cover is pressed against the limiting ring groove. Through this setting, the connection strength of the protective cover is further improved, preventing it from falling off, and improving the overall stability.

[0012] It is further configured that the protective cover is provided with a first active cavity and a second active cavity respectively corresponding to the positions of the first threaded pin and the second threaded pin, and the length of the second active cavity is greater than that of the first active cavity. Through this configuration, the positions of the first threaded pin and the second threaded pin are vacated to prevent interference, thereby improving the tightness and making the overall structure more stable.

[0013] In summary, the tail end tensioner extends the threaded pin on the male pressure block so that the female pressure block can be connected to the cable that needs to be tightened without the outer ring of the female pressure block being separated from the male pressure block, so that the male pressure block and the female pressure block are always kept as a whole, achieving the advantage of no need for complete disassembly in terms of operation, and achieving the beneficial effect of reducing the risk of falling objects from high altitude.
