Abstract
The utility model provides a multifunctional herringbone ladder comprising a left ladder assembly and a right ladder assembly, wherein the left ladder assembly and the right ladder assembly are arranged oppositely; the top ends of the left ladder assembly and the right ladder assembly are respectively hinged with pedals; the opposite side edges of the two pedals are connected through a hinge; locking devices are arranged at the hinged parts of the left and right ladder assemblies and the pedals and the connected part of the two pedals connected through the hinge; draw bars connected with the two ladder assemblies are arranged at two sides of the left and right ladder assemblies. By using the multifunctional herringbone ladder provided by the utility model, a working mode of a trapezoidal work platform also can be combined besides that the function of a common herringbone ladder is finished, and operation requirements in different occasions are conveniently met.
Description
Technical field
The utility model relates to a kind of ladder, especially a kind of multi-functional herring ladder.
Background technology
Double ladder is extremely widely used in daily family expenses and construction site, no matter be indoor or outdoor can both use.By two identical vertical ladders, the mode by top twisting connects as a whole common double ladder.Both can merge as vertical ladder use by two legs in use, and also two legs can be separated to certain angle and use as double ladder.When work, the former need to have fixture to support, and the latter can only singlehandedly work or take to lean against the work of ladder both hands.These two kinds of modes are very easily tired, the work of existence and stability and poor stability, the personnel shorter shortcoming of holding time all.Can not meet the instructions for use of many Code in Hazardous Special Locations.
Summary of the invention
The purpose of this utility model is to provide a kind of multi-functional herring ladder, except meeting the various instructions for uses of common double ladder, can also build small-sized working platform, both can be manned, can place again the small articles such as Work tool that operation used, equipment part, meet various work requirements, increase work efficiency.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of multi-functional herring ladder, comprise left and right ladder, left and right ladder is oppositely arranged, it is characterized in that: the top of described left and right ladder is hinged with respectively pedal, two relative sides of pedal are connected through the hinge, and the position that the position that left and right ladder and pedal are hinged and two pedals are connected through the hinge is respectively equipped with locking device, and the side of left and right ladder both sides is provided with the pull bar that connects two ladders.
Improvement to technique scheme: described locking device is comprised of latch hook and snap close, each group latch hook and snap close be the corresponding both sides that are arranged on hinge point respectively.
Improvement to technique scheme: described pull bar is comprised of tooth bar and teeth groove, tooth bar and teeth groove are arranged on respectively the side of left and right ladder, between tooth bar and teeth groove, are provided with fastening bolt.
Further improvement to technique scheme: the panel of described pedal is lattice-shaped.
Beneficial effect:
Use multi-functional herring ladder described in the utility model, except completing the function of common double ladder, can also be combined into the mode of operation of trapezoidal working platform, facilitate the job requirements of different occasions.Pedal can be by being folded to form working platform, and pull bar can be controlled the opening degree of ladder.Described multi-functional herring ladder, the one, complete the various requirement of common double ladder; The 2nd, be combined into trapezoidal working platform, personnel's area of standing is larger, breaks away from the restriction that common double ladder can not be stood for a long time, can reduce security risk, improves comfort level, and reduction personnel are tired, alleviate working strength, lengthen working hours; The 3rd, can place tool bag on the platform forming, the small-sized object such as equipment, component, avoid personnel repeatedly upper and lower ladder get thing; The 4th, ladder movable part adopts coaxial screw rod (or hinge) to connect, and secondary hinge and fixed stay capable of regulating ladder height also guarantee the rigidity of ladder, generally platform are maintained to 2 meters below height, to guarantee personal security and dependable performance during work high above the ground.
Accompanying drawing explanation
Fig. 1 is that the utility model is as the structural representation of trapezoidal ladder.
Fig. 2 is that the utility model is as the structural representation of double ladder.
Fig. 3 is that the utility model is as the structural representation of vertical ladder.
The specific embodiment
As Fig. 1, Fig. 2, a kind of multi-functional herring ladder of the utility model shown in Fig. 3, comprise a left side, right ladder 1, 2, left, right ladder 1, 2 are oppositely arranged, left, right ladder 1, 2 top is hinged with respectively pedal 3, 4, pedal 3, 4 panel is lattice-shaped, pedal 3, 4 relative sides are connected through the hinge, left, right ladder 1, 3 with pedal 3, 4 hinged position and pedals 3, 4 positions that are connected through the hinge are respectively equipped with locking device, described locking device is comprised of latch hook 5 and snap close 6, each group latch hook 5 and snap close 6 be the corresponding both sides that are arranged on hinge point respectively, the both sides of left and right ladder 1,2 are provided with the pull bar that connects ladder 1,2, and described pull bar is comprised of tooth bar 7 and teeth groove 8, and tooth bar 7 and teeth groove 8 are arranged on respectively the side of left and right ladder 1,2, between tooth bar 7 and teeth groove 8, are provided with fastening bolt 9.
The utility model multi-functional herring ladder, the utility model has three kinds of working methods as shown in Figure 1, Figure 2, Figure 3 shows:
(1) locking device of two pedal opposite flanks, ladder top is in opening as shown in Figure 3, and the locking device below ladder top, in locking state, is merged into 0 degree by two legs and is vertical ladder.
(2) left and right ladder is separated into certain angle and can forms double ladder as shown in Figure 2.When ladder is adjusted into double ladder, the tooth bar and the teeth groove that are attached to left and right ladder side are rotated to level, by fastening bolt, adjust locking, guarantee that left and right ladder can not slip off.
(3) locking device of left and right ladder and pedal hinge point, in opening, makes the locking device of pedal relative side hinge point in locking state as shown in Figure 1, and two pedals are formed to a plane.Left and right ladder is separated into after certain angle, the tooth bar and the teeth groove that are attached to left and right ladder side are rotated to level, by fastening bolt, adjust locking, guarantee that left and right ladder can not slip off.
Claims (4)
1. a multi-functional herring ladder, comprise left and right ladder, left and right ladder is oppositely arranged, it is characterized in that: the top of described left and right ladder is hinged with respectively pedal, two relative sides of pedal are connected through the hinge, the position that the position that left and right ladder and pedal are hinged and two pedals are connected through the hinge is respectively equipped with locking device, and the side of left and right ladder both sides is provided with the pull bar that connects two ladders.
