Full ladder, staff probably due to crank and fall injury, for the sake of security, it is necessary to constantly move double ladder,
Cause the pruning efficiency than relatively low.
In order to solve the problem of above is present, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of this utility model be in view of the shortcomings of the prior art so that provide a kind of design science, high safety, can
The emergency staircase trimmed for dungarunga that coverage area is wide, the pruning efficiency is high.
To achieve these goals, the technical scheme that the utility model is used is：
A kind of emergency staircase trimmed for dungarunga, it includes double ladder main body, and the double ladder main body includes four ladders
Leg, bar and self-locking telescoping rod, the self-locking telescoping rod and the handrail are hinged with the middle and upper part of the every terraced leg
Bar is also articulated to together, wherein each pin joint is misaligned.
Based on above-mentioned, on two terraced legs of same side, it is hinged with wherein being hinged with a terraced leg on strut, another terraced leg
Multiple fixing holes are equipped with strut fix bar, the strut along its length, each fixing hole is provided with internal thread, the support
The bar fix bar correspondence strut offers the correspondence fixing hole on strut groove, the side wall of the strut groove and is provided with two admittedly
Determine bolt.
Based on above-mentioned, the every terraced leg bottom is provided with strap brake universal wheel wheel.
Described on base, one end of the bar is hinged on the top of the terraced leg, one end hinge of the self-locking telescoping rod
It is connected at the terraced leg below the bar, the other end of the self-locking telescoping rod is hinged on the middle part of the bar.
Described on base, the self-locking telescoping rod is socketed successively by Multi section bar to be formed, installation locking bolt at two adjacent sections bar.
The utility model has substantive distinguishing features and progress compared with the prior art, and specifically, the utility model is common
The bar, the terraced leg and bar and self-locking telescoping rod composition on the terraced leg are added on the basis of double ladder
One triangle, by adjusting and locking the length of the self-locking telescoping rod, realizes lock of the bar in different angles
Fixed, in the case where centre of body weight skew is more, hand grips hand lever so that arm, human body and ladder constitute stable triangular structure,
Staff grasps the bar with regard to that can trim some distant branches and leaves, effectively increases security；Pass through the strut
With the cooperation of the strut fix bar, the opening angle of whole emergency staircase can be adjusted, it is whole after being locked with the fixing bolt
Individual ladder constitutes stable triangle, further increases security；It has design science, high safety, reachable range
Extensively, the high advantage of the pruning efficiency.
Brief description of the drawings
Fig. 1 is to be used for the structural representation for the emergency staircase that dungarunga is trimmed in the utility model.
In figure：1. terraced leg；2. bar；3. self-locking telescoping rod；4. strut；5. strut fix bar；6. strap brake universal wheel
Wheel；41. fixing hole；51. strut groove；52. fixing bolt.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in figure 1, a kind of emergency staircase trimmed for dungarunga, it includes double ladder main body, the double ladder main body
Including four terraced legs 1, bar 2 and expansion link self-locking telescoping rod 3 are hinged with the middle and upper part of every terraced leg 1, expansion link is certainly
Together with lock expansion link 3 is also articulated to bar 2, wherein each each pin joint is misaligned, the expansion link self-locking telescoping rod 3
On eccentric locking mechanism is provided with to lock the length of expansion link self-locking telescoping rod.
During specific installation, one end of the bar 2 is hinged on the top of the terraced leg 1, the one of the self-locking telescoping rod 3
End is hinged at the terraced leg 1 of the lower section of bar 2, and the other end of the self-locking telescoping rod 3 is hinged in the bar 2
Portion.The self-locking telescoping rod 3 is socketed successively by 3 poles to be formed, installation locking bolt at two adjacent sections bar.
In other embodiments, it can also be locked by the retaining mechanisms of other species, such as eccentric locking mechanism, partially
Heart retaining mechanism has the simple advantage of lock operation.
The terraced leg 1 and the self-locking telescoping rod 3 and bar 2 that are hinged on the terraced leg constitute a triangle, wherein
The length of self-locking telescoping rod 3 can change, therefore bar 2 can turn in the range of the length change of self-locking telescoping rod 3
It is dynamic；When the length of self-locking telescoping rod 3 is locked, the angle of bar 2 is also fixed, and staff can grasp bar 2
It is operated, farther distance range can not only be reached, and improve security.
In order to further improve security, on two terraced legs 1 of same side, wherein strut 4 is hinged with a terraced leg 1,
It is hinged with another terraced leg 1 on strut fix bar 5, strut 4 and is equipped with multiple fixing holes 41 along its length, each fixing hole 41
Internal thread is provided with, the correspondence strut 4 of strut fix bar 5 offers correspondence fixing hole 41 on strut groove 51, the side wall of strut groove 51
It is provided with two fixing bolts 52；In the double ladder main body opened with certain angle, strut 4 is inserted in strut groove 51, it is micro-
The angle for adjusting the double ladder main body to open so that two fixing bolts 52 shine neat with fixing hole 41, then, rotary fixing screw
Bolt 52, strut 4 and strut fix bar 5 are fixed together, the fixation of double ladder main body opening angle is realized, the emergency staircase is improved
Stability.
Move for convenience, strap brake universal wheel wheel is provided with the bottom of every terraced leg 1；When needing to move, it will brake
Open, to needing behind position, by brake lock.
When specifically used, first, the double ladder main body opened with certain angle is fixed by the strut 4 and strut
Bar 5 coordinates, and double ladder main body opening angle is locked；Then, pushing it to needs position, locking strap brake universal wheel 6；Most
Afterwards, staff as needed, adjusts the anglec of rotation of the bar 2, dungarunga is trimmed.
