In some embodiments, the number of crossbars 300 is prefabricated, a corresponding number of crossbars 300 is set according to the wiring scheme, but the crossbars 300 thus set cannot be changed after production, and for erection of cable sets requiring an increased number of cables, a multi-loop type pay-off rack corresponding to the number of crossbars 300 needs to be produced again.

In other embodiments, the number of the cross bars 300 can be changed according to the actual situation of the site, so that the cross bars are more universal, and the temporary additional lines can be more conveniently realized.

In this embodiment, the mounting base 100 includes a plurality of mounting blocks 120, the plurality of mounting blocks 120 are arranged in a vertical direction, two adjacent mounting blocks 120 are detachably connected, and each mounting block 120 is connected with a cross bar 300 extending in a front-rear direction.

The constructor can add or reduce the number of the installation blocks 120 in the process of construction, and change the number of the cross bars 300, thereby changing the number of the transverse insulators 500 and the vertical insulators 600 that can erect the cable.

For example, for a four-wire cable, that is, each cable group has four cables, four cross bars 300 need to be provided on the mount 100, and thus, four mounting blocks 120 are provided, so that the four-wire cable can be installed. For two-wire cables, i.e. two cables for each cable group, two crossbars 300, i.e. two mounting blocks 120, are required to be arranged on the mounting base 100, so that the two-wire cables can be erected.

It is to be understood that the two adjacent mounting blocks 120 may be implemented by a clamping manner, or may be implemented by a threaded connection manner, and the connection between the mounting block 120 located at the uppermost position and the fixing block 110 may be implemented by a clamping manner, or may be implemented by a threaded connection manner, which is not limited herein specifically.

It can be understood that the third fixing section 410 is sleeved with one vertical insulator 600, and the three third extension sections 420 are respectively sleeved with one vertical insulator 600, so that a four-wire cable can be erected.

When two cables are to be laid, two crossbars 300 are provided for arranging two cables of a cable set, and only the vertical bar 400 having one third extension 420 is required. The vertical bar 400 can pass through the first through hole from the upper end of the top bar 200 and pass through the second through holes of the two cross bars 300 to reach below the lowermost cross bar 300. It can be appreciated that, since only one third extension section 420 is provided, the length of the vertical rod 400 can be shortened, the occupied space of the whole multi-loop pay-off rack can be reduced, and the multi-loop pay-off rack is more attractive.

It is understood that the stopper 430 is disposed above the third fixed segment 410. The connection between the third fixing segment 410 and the third extension segment 420 may be implemented through a threaded connection, or may be implemented through a clamping connection.

The stop collar 330 is further provided with a fourth through hole, and the fourth through hole extends along the up-down direction and is mutually communicated with the third through hole. When the stop collar 330 is sleeved on the second fixing section 310 or the second extending section 320, the fourth through hole can be overlapped and communicated with the second through hole on the second fixing section 310 or the second extending section 320, and the vertical rod 400 can pass through the fourth through hole to reach the lower part of the cross rod 300.

It will be appreciated that the number of the spacers 330 is identical to that of the lateral insulators 500, and each spacer 330 is disposed on the front side of one lateral insulator 500, that is, the lateral insulators 500 and the spacers 330 are disposed at intervals in the front-rear direction.

It will be appreciated that the spacing sleeve 330 can limit the moving distance of the transverse insulator 500 in the front-rear direction, so as to avoid the transverse insulator 500 from being too close to the vertical rod 400 to affect the installation of the vertical insulator 600.

In some embodiments, both the lateral insulator 500 and the vertical insulator 600 are provided with two buffer washers 510. Wherein, two buffer washers 510 of the lateral insulator 500 are respectively disposed at the front end face and the rear end face of the lateral insulator 500, and two buffer coils of the vertical insulator 600 are respectively disposed at the upper end face and the lower end face of the vertical insulator 600.

It can be appreciated that the buffer gasket 510 can protect the transverse insulator 500 and the vertical insulator 600, buffer the collision between the vertical rod 400 or the mounting seat 100 and the transverse insulator 500, and prevent the collision between the push rod 200 or the cross rod 300 and the vertical insulator 600 from being broken due to the collision between the transverse insulator 500 and the vertical insulator 600 and other components when the transverse insulator 500 and the vertical insulator 600 are mounted or during the cable erection process.
