Abstract

The utility model relates to a buckling-type safety herringbone ladder, which comprises two ladder frames of which the upper ends are connected by a rotating shaft. Each ladder frame consists of ladder legs and stepping beams connected between the ladder legs. The ladder legs of the two ladder frames are connected by a turn buckle. A stretching screw at one end of the turn buckle is a closed ring, while a stretching screw at the other end thereof is an elastic open ring. The closed ring is connected with a fixed cap head screw on the ladder leg of one ladder frame. The elastic open ring is connected an adjustable cap head screw arranged on the ladder leg of the other ladder frame. The buckling-type safety herringbone ladder has the advantages of simple, reasonable, economic and applicable design and good safety and is very suitable for popularization and application.

Building installation engineering, often need to use " herringbone " ladder of various materials, in the use in order to prevent the slippage of " herringbone " ladder ladder leg, usually adopt common rope, electric wire or iron wire with the simple colligation of two legs, be easy to because of rope rots, iron wire corrosion and electric wire brittle failure, the accident that causes terraced leg slippage to cause the constructor to fall from ladder is serious even cause casualty accident.
At above-mentioned situation, common " herringbone " ladder is carried out technological improvement, it is simple to set up fabrication and installation, the antiskid regulated snap close safety device convenient to use, can set up angle according to the terraced leg of construction needs adjusting ladder, and solve the various safety problems that terraced leg slippage causes in the work progress.
The utility model content
The purpose of this utility model is the security performance that is widely used in building operations installing engineering " herringbone " ladder in order to improve.
Content of the present utility model is: a kind of bayonet type safety herringbone ladder, comprise two ladders that connect by rotating shaft by the upper end, described ladder is made up of the terraced leg and the crossbeam of marking time that is connected between the terraced leg, adopt flower basket bolt to connect between the terraced leg of described two ladders, the adjustment screw rod of described flower basket bolt one end is a closed-loop, and the adjustment screw rod of the other end is an elastic opening ring; Described closed-loop is connected with locking cap head screw rod on the terraced leg, and described elastic opening ring is connected with adjustable cap head screw rod on being arranged on another terraced leg.
The non-cap end of described locking cap head screw rod and adjustable cap head screw rod be fixed on terraced inboard leg to end a plate integrally welded.
Described elastic opening ring comprises the insurance card that ring body and opening part are provided with, and this insurance card is connected with ring body by spring.
On terraced leg, the bottom that is positioned at described locking cap head screw rod is provided with leaves standstill screw rod, this non-cap end that leaves standstill screw rod be fixed on the terraced leg to end a plate integrally welded.
A described only plate is positioned at the inboard of terraced leg.
The lower end of described terraced leg is set with the non-slip rubber pad.
The beneficial effects of the utility model
This bayonet type safety herringbone ladder structure design is simple, reasonable, economical, suitable, efficiently solve that the workman adopts rope, electric wire or iron wire etc. with the existing security hidden trouble of the simple colligation of ladder two legs in the work progress, can guarantee the safe handling of ladder.Considered that in design ladder sets up the angular transformation problem, employing can be regulated gaily decorated basket screw rod and well solve this problem, and fabrication and installation are simple, and are convenient to use, and the nonrecurring charge input is with low cost.
Flower basket bolt one end of this bayonet type safety herringbone ladder is provided with elastic opening ring and is connected with adjustable cap hook bolt on the terraced leg, and insurance card is set at this split ring place, this herringbone support body is installed to be supported conveniently, another is convenient can also to guarantee that it can slippage, improves its security performance.
Being provided with in the bottom of locking cap head screw rod and leaving standstill screw rod is in order to pack up the not time spent at this herringbone support body, above the elastic opening ring of flower basket bolt is installed in, thereby avoids its free activity to cause damaging or hurts sb.'s feelings.
It also is to be provided with for security purpose that the lower end of its terraced leg is set with the non-slip rubber pad.

The specific embodiment
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, number in the figure represents meaning as follows:
1-rotating shaft, 2-ladder leg, 3-mark time, and only a plate, 9-leave standstill screw rod, 10-non-slip rubber pad, 11-spring, 12-ring body for crossbeam, 4-locking cap head screw rod, 5-gaily decorated basket screw rod, 6-insurance card, 7-adjustable cap head screw rod, 8-
A kind of bayonet type safety herringbone ladder, comprise two ladders that connect by rotating shaft 1 by the upper end, described ladder is made up of the terraced leg 2 and the crossbeam 3 of marking time that is connected between the terraced leg 2, adopt flower basket bolt 5 to connect between the terraced leg 2 of described two ladders, the adjustment screw rod of described flower basket bolt 5 one ends is a closed-loop, and the adjustment screw rod of the other end is an elastic opening ring; Described closed-loop is connected with locking cap head screw rod 4 on the terraced leg, and described elastic opening ring is connected with adjustable cap head screw rod 7 on the terraced leg that is arranged on the opposite side ladder.
The non-cap end of described locking cap head screw rod 4 and adjustable cap head screw rod 7 be fixed on terraced leg 2 inboards to end a plate 8 integrally welded.
Described elastic opening ring comprises the insurance card 6 that ring body 12 and opening part are provided with, and this insurance card 6 is connected with ring body 12 by spring 11.
On terraced leg 2, the bottom that is positioned at described locking cap head screw rod 4 is provided with leaves standstill screw rod 9, this non-cap end that leaves standstill screw rod 9 be fixed on the terraced leg 2 to end a plate 8 integrally welded.
A described only plate 8 is positioned at the inboard of terraced leg 2.
The lower end of described terraced leg 2 is set with non-slip rubber pad 10.
During use, two ladders are bypassed into herringbone around the shaft, after arriving suitable angle or height, the elastic opening ring of flower basket bolt is taken off on the adjustable cap hook bolt on the terraced leg that is suspended to the opposite side ladder from leaving standstill bolt, tighten this adjustable cap head then, again by adjusting height that flower basket bolt further adjusts this ladder, thereby finish the installation of this ladder to proper height.
Certainly in order to improve its intensity, also the another side of this ladder also is provided with same flower basket bolt and locking cap hook bolt, adjustable cap hook bolt again, forms more solid embodiment, also belongs to the protection domain of this patent, does not describe in detail at this.
