In order to reduce costs and alleviate the weight of ladder, described bearing 1 and Body of pillar are hollow bodies; Described Body of pillar is individual layer or multilayer in the combination of ladder, and bearing 1 is individual layer in the combination of ladder.
In order to reduce the consumption of ladder and be convenient to store and keeping, all building blocks of described ladder can be reused.
Conveniently pack and transport, described pin is stepped on 13 fixing employing pin on Body of pillar and is connected and fixed, and pin is stepped on 13 one end be merely able on Body of pillar to connector 3 and drawn in, is convenient to packaging; Described Body of pillar and bearing 1 can be dismantled completely and become independent parts, are beneficial to packaging and transport.
Ladder is when assembling, bearing 1 is put on the ground, one end of brake hole 9 is had by Body of pillar to insert in the Inner taper hole 12 of bearing 1, under the effect of self gravitation, the male cone (strobilus masculinus) 10 of pillar 2 is naturally fitted with the inner conical surface 11 of bearing 1 and fixes, and the gravity depressed from pillar 2 is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted; When the male cone (strobilus masculinus) 10 of pillar 2 inserts Inner taper hole 12, brake bar 4 is inserted in brake hole 9, when brake bar 4 enters into the position of brake head, the leading section of brake bar 4 pushes the arcwall face oblique promotion brake head compression thrust spring 7 of locking head and outwards makes a concession, and the front end of brake bar 4 passes through the position of brake head; When brake bar 4 is through after brake head, when the male cone (strobilus masculinus) 10 of pillar 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of bearing 1, brake head enters in the breaker slot on brake bar 4 under the powered of thrust spring 7, facing directly of brake head coordinates locked brake bar 4 to stand fast with the one side of lock groove 9 right-angle side, the inner conical surface 11 of laminating and male cone (strobilus masculinus) 10 locked, complete fixing and locking of Body of pillar and bearing 1.Afterwards, one end of brake hole 9 is again had by Body of pillar to insert in the Inner taper hole 12 of connector 3 in Inner taper hole 12 in connector 3 on Body of pillar, under the effect of self gravitation, the male cone (strobilus masculinus) 10 of pillar 2 is naturally fitted with the inner conical surface 11 of connector 3 and fixes, and the gravity depressed from pillar 2 is larger, it is closely and more more firm that inner conical surface 11 and male cone (strobilus masculinus) 10 are fitted; When the male cone (strobilus masculinus) 10 of pillar 2 inserts Inner taper hole 12, brake bar 4 is inserted in brake hole 9, when brake bar 4 enters into the position of brake head, the leading section of brake bar 4 pushes the arcwall face oblique promotion brake head compression thrust spring 7 of brake head and outwards makes a concession, and the front end of brake bar 4 passes through the position of brake head; When brake bar 4 is through after brake head, when the male cone (strobilus masculinus) 10 of pillar 2 contacts firm with the inner conical surface 11 of the Inner taper hole 12 of connector 3, brake head enters in the breaker slot on brake bar 4 under the powered of thrust spring 7, facing directly of brake head coordinates locked brake bar 4 to stand fast with the one side of lock groove 9 right-angle side, laminating Inner taper hole 12 and male cone (strobilus masculinus) 10 locked; Afterwards, the male cone (strobilus masculinus) 10 of Body of pillar can insert in the Inner taper hole 12 of Body of pillar by Using such method again, completes being connected and fixed and locking between Body of pillar and Body of pillar.
During the Body of pillar of dismountable, pull the pin handle of pin 6, after the brake head of pin 6 front end exits the breaker slot on brake bar 4, Body of pillar upwards one is drawn or one lifts and automatically will separate with the Inner taper hole 12 in the connector 3 of a Body of pillar below, and brake bar 4 skids off from brake hole 9; Now, as long as Body of pillar upwards one is lifted, the male cone (strobilus masculinus) 10 of Body of pillar will separate automatically with the Inner taper hole 12 of the connector 3 of the Body of pillar of below.During the Body of pillar that dismounting bearing 1 is fixed, pull the pin handle of pin 6, after the brake head of pin 6 front end exits the breaker slot on brake bar 4, Body of pillar upwards one is drawn or one lifts and automatically will separate with the Inner taper hole 12 of bearing 1, and brake bar 4 skids off from brake hole 9; Now, as long as Body of pillar upwards one is lifted, pillar 2 will separate automatically with bearing 1.
The assembly and disassembly of Body of pillar and bearing 1 and connector 3 are very convenient, just can complete without any need for instrument.
Fire fighter is when climbing fire ladder, pin is stepped on 13 pin on Body of pillar and is stepped on 13 and climb up, and can climbing one section of assembling one section, taking with oneself needing the Body of pillar of height, when climbing to the top of ladder in the process of cat ladder, climb up again after inserting a Body of pillar in superincumbent Inner taper hole 12 again.During descending stair, step down in pin and step on 13 and down climb, next section tears a Body of pillar open, very convenient.
