Description
Technical field
This utility model relates to a kind of ladder, specifically a kind of Telescopic herringbone ladder.
Background technology
When pruning trees or power equipment maintaining ascend a height operation, ladder can be commonly used, conventional vertical ladder is the most portable and needs people to buttress less important work, waste time and energy, and length is fixed, use inconvenience, notification number is that the patent of CN201176847Y discloses a kind of Telescopic herringbone ladder, its ladder is socketed to form by multistage section of ladder, the installation quantity of section of ladder can be selected according to actual contour height, the not used time, section of ladder is dismantled, easy to carry, but use this device, owing to ladder is set to tubulose, when strutting ladder work, only with support ground, four ladder bottoms, contact area is little, staff's operationally easily overturning, there is the biggest potential safety hazard, and circular tube shaped ladder is difficult to when installing and supporting support install, there is certain limitation.
Utility model content
The purpose of this utility model, it is simply that for solving the problem that prior art exists, and devise a kind of Telescopic herringbone ladder, make the stability of double ladder strengthen, it is ensured that safety during staff's operation.
The technical solution of the utility model is: a kind of Telescopic herringbone ladder, including left socle and right support, described left socle and right support are formed by fixed mount and expansion bracket, it is respectively arranged with adjustment hole on the two sides of described fixed mount and expansion bracket, described expansion bracket is scalable to be connected to inside fixed mount, it is characterized in that: the upper end thereof of described fixed mount has connecting rod, bolt mounting holes I it is arranged at intervals with in described connecting rod, regulation framework it is separately installed with on the side that said two fixed mount is relative, it is arranged at intervals with bolt mounting holes II on described regulation framework, this regulation framework has been bolted to connection support bar, the bottom of described support bar is provided with sucker.
Above-mentioned regulation framework includes base plate and left plate connected vertically with the base plate left and right sides and right plate, described base plate is welded to connect with fixed mount, described bolt mounting holes II is separately positioned on left plate and right plate, and one_to_one corresponding, by bolt mounting holes II and then support bar is fixed, strengthen the stability of Telescopic herringbone ladder.
The upper end of above-mentioned support bar is provided with the through hole coordinated with bolt mounting holes II.
The quantity of above-mentioned bolt mounting holes II is set to 3 ~ 5, in order to the differing heights after strutting according to double ladder is connected fixing with suitable bolt mounting holes II for support bar.
It is bolted to connection between connecting rod on above-mentioned two fixed mount, struts to suitable height at double ladder, by connecting rod, the angle between left socle and right support is fixed.
The cross section of above-mentioned fixed mount and expansion bracket is disposed as rectangle, in order to install connecting rod and regulation framework.
The beneficial effects of the utility model can be drawn by such scheme: in this utility model, after left socle and right support strut, two connecting rods is bolted, it is possible to fixing angle between left socle and right support；By arranging regulation framework and support bar, height after can strutting according to double ladder is actual, support bar one end is made to be connected with suitably bolt mounting holes II on regulation framework, the other end is connected by sucker and ground are firm, and then the stability of enhancing double ladder, improve safety coefficient during staff's operation.
As can be seen here, this utility model compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation regulating framework in this utility model；
Fig. 3 is the structural representation of support bar in this utility model.
Wherein, 1 is expansion bracket, and 2 is adjustment hole, and 3 is connecting rod, and 4 is bolt mounting holes I, and 5 is bearing pin, 6 is fixed mount, and 7 is support bar, and 8 is bolt mounting holes II, and 9 is regulation framework, and 7-1 is support bar body, 7-2 is sucker, and 7-3 is through hole, and 9-1 is base plate, and 9-2 is left plate, and 9-3 is right plate.
Detailed description of the invention:
In order to be more fully understood that this utility model, explain in detail embodiment of the present utility model below in conjunction with the accompanying drawings.
Detailed description of the invention: a kind of Telescopic herringbone ladder, including left socle and right support, left socle and right support are formed by fixed mount 6 and expansion bracket 1, the cross section of fixed mount 6 and expansion bracket 1 is disposed as rectangle, adjustment hole 2 it is respectively arranged with on the both sides of fixed mount 6 and expansion bracket 1, expansion bracket 1 is scalable is connected to fixed mount 6 inside, and is bolted to connection, and then adjusts the whole height of Telescopic herringbone ladder.The upper end of fixed mount 6 is hinged with connecting rod 3 by bearing pin 5, connecting rod 3 is arranged at intervals with bolt mounting holes I 4, is bolted to connection between the connecting rod 3 on two fixed mounts 6.Regulation framework 9 it is separately installed with on the side that two fixed mounts 6 are relative, regulation framework 9 include base plate 9-1 and with base plate 9-1 left and right sides left plate connected vertically 9-2 and right plate 9-3, base plate 9-1 is welded to connect with fixed mount 6, bolt mounting holes II 8 is separately positioned on left plate 9-2 and right plate 9-3, and one_to_one corresponding, described bolt mounting holes II 8 interval is arranged, and its quantity is set to 3 ~ 5.This regulation framework 9 has been bolted to connection support bar 7, and the bottom of support bar 7 is provided with sucker 7-2.The upper end of support bar 7 is provided with the through hole 7-3 coordinated with bolt mounting holes II 8.
When operation of ascending a height uses Telescopic herringbone ladder, left socle and right support being strutted to suitable angle, regulation expansion bracket 1 makes the whole height of double ladder meet requirement, is connected fixing for connecting rod 3 by bolt, makes the whole height of double ladder keep fixing；After regulation support bar 7 to suitable position, being connected fixing with the bolt mounting holes II 8 of regulation framework 9 for its one end, the other end is connected by sucker 7-2 is firm with ground, and then strengthens the stability of double ladder, improves the safety coefficient of staff's work.
