Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail。
With reference to shown in Fig. 1, a kind of cat ladder draw-bar box, including casing 1 and pull bar 2, casing 1 profile is rectangular body, is designed to fillet in edges and corners, makes casing 1 profile more mellow and fuller, is avoided that again wedge angle arranges potential safety hazard that may be present。Worn a pull bar 2 at the back side of casing 1, pull bar 2 can carry out flexible pulling, and regulates height, thus convenient in the use procedure of pull bar 2 casees。
With reference to described in Fig. 2-3, it is provided with rotating shaft 6 near the angle of intersection place of bottom surface Yu the back side in two sides of casing 1, rotating shaft 6 is connected to a rotating disk, rotating disk profile is disc, it is fixedly connected with first bevel gear 42 near the one side of casing 1 at rotating disk, it is coaxially disposed with rotating disk, gear is distributed on the circumference of rotating disk, the other end of rotating disk is provided with planar rectangular screw thread, it is provided with three circumferentially equally distributed claws 41 with screw-threaded engagement, claw 41 radially can move on rotating disk, claw 41 is rectangle strip, perpendicular with rotating disk end face, and it is rotationally connected cat ladder pulley 3 at claw 41 away from the one end in the center of circle, cat ladder pulley 3 is made up of gum, gum wheel has high resiliency, high intensity, high resilience, the damping effect making wheel becomes better, also more wear-resisting。It is achieved thereby that claw 41 can move on rotating disk, regulate the distance of cat ladder pulley 3 and the rotating disk center of circle, the arc length between adjacent cat ladder pulley 3 is made to convert, be conducive to deacclimatizing the cat ladder requirement of differing heights stair, one of them wheel can be made to set aside to upper level step, an adjacent wheel is positioned at next stage step, utilize the effect of rotating shaft 6, casing 1 is inclined to set, pull pull bar 2, cat ladder pulley 3 just can be made to carry out cat ladder, make the upper ladder process of pull bar 2 casees become easy and convenient。
In addition, it is meshed with the first bevel gear 42 and is provided with the second bevel gear 51, second bevel gear 51 volume is little, it is positioned on the circumference of the first bevel gear 42, radial direction along rotating disk, circle centre position the second bevel gear 51 has worn a rotary handle 52, it is thus possible to driven the rotation of the first bevel gear 42 by rotary handle 52, rotating disk is made to rotate, utilize the planar rectangular screw thread on rotating disk end face, just can make to carry out becoming into discrete in engaging the claw 41 arranged with it simultaneously, achieve the adjusted in concert of three cat ladder pulleys 3, the arc length that ensure that between adjacent cat ladder pulley 3 on circumference is isometric, cat ladder process can be made more smooth, the main step table top of pulley card will not be there is because of not decile。
It is provided with one piece of limiting plate 7 additionally, hinged above rotating shaft 6, on the side of casing 1, and is provided with annular groove in corresponding rotating shaft 6, it is possible to be embedded with limiting plate 7。When pull bar needs to carry out cat ladder for 2 casees, limiting plate 7 is dug, and does not conflict with rotating shaft 6, makes rotating shaft 6 normal rotation。And when needs pull bar 2 casees moves on level land, first keep conflicting by the two of which pulley of cat ladder pulley 3 and ground, after having regulated, limiting plate 7 is turned down, two vertical plates and the horizontal plate that make limiting plate 7 are all inconsistent with annular groove, so that rotating shaft 6 cannot be carried out rotating, serve locking effect, at this moment, cat ladder pulley 3 then can be utilized to realize the movement on level land, achieving dual-purpose effect, thus eliminating original translating pulleys, making structure configuration more reasonable。
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model。
