The strut 22 is connected respectively, and the top of the support feet 1 is attached by cross bar 21, the cross bar 21 on the support feet top
On multi-joint telescoping part is installed, the support feet 1 and the strut 22 are hollow circular-tube structure, the strut 22 of upper strata extensible member
It is inserted into the strut 22 of lower floor's extensible member, the strut 22 of orlop extensible member 2 is inserted into support feet 1, and the fixing piece 3 is used
In fixing strut 22 when extensible member 2 is unfolded, prevent extensible member 2 from retracting, the telescopic joint 7 is sleeve-type expansion joint, by insulating
Material is made, and is sleeved on the top of 22/ support feet 1 of strut, as the insulation between two struts and between strut and support feet
Part.
In use, pulling straight out each section extensible member 2, after moving extreme position to, it is anti-that fixing piece 3 fixes corresponding strut 22
Only extensible member 2 retreats, and can be used after the expansion of such hanging ladder, without using when, fixing piece 3 can be operated, by all extensible members 2
Retract, can reduce the area occupied of hanging ladder, ladder shrinks long less than 1 meter, can be placed on automobile boot and be convenient for carrying, complete
Hanging ladder height is up to 3 meters during full expansion.
This hanging ladder is made using glass fibre tubing, has a light weight, it is firm in structure it is beautiful and generous, durable,
The advantages of corrosion-resistant and good insulation performance.
Preferably, hook 4 is installed, 4 one end of the hook are fixed on top and are stretched on the cross bar 21 of top extensible member 2
On the cross bar 21 of contracting part 2, the other end is used to catch on the ladder stand steel pipe among steel tube tower cat ladder, so that fixed hanging ladder, on ground not
When flat or soft, safety problem when the upper descending stair of personnel and operation ensure that, it is not necessary to specially send one to two personnel to help ladder
Son ensures personnel safety, reduces human cost.In addition, being provided with Anti-slip cover 6 in the bottom of support feet 1, hung for increasing
Ladder and the frictional force on ground, have a good antiskid effect, environmentally friendly and the advantages of ensure personal safety.
Preferably, fixed band 5 is provided with the cross bar 21 of the bottom, the fixed band 5 is pricked using the velcro of strip
Band, after hanging ladder is shunk completely, can tie all cross bars 21 with fixed band 5 and be fixed, avoid extensible member 2 from scattering, increase
The stability of hanging ladder, is convenient for carrying.
Referring to 7 scheme of installation of telescopic joint of Fig. 2, the telescopic joint 7 is sleeve-type expansion joint, convenient installation, described to stretch
