Detailed description of the invention

Illustrate below in conjunction with accompanying drawing and the utility model elaborated:

As Figure 1-3,

A cargo hook gear for ladder, it comprises suspension rod and is fixedly connected on the hook bar of suspension rod lower end; Described suspension rod upper end forms the hook 1 be hooked on crosspiece; Described hook bar lower end is upwards bent to form hook 3; Formed in the middle part of described hook bar with hook 1 homonymy and the restriction protrusion 2 leaned at crosspiece lower surface.

Hook 1 is hooked on one of them crosspiece of ladder, and restriction protrusion 2 leans another crosspiece lower surface at ladder, makes on ladder two crosspieces be stuck between hook 1 and restriction protrusion 2 like this, thus enables stable being fixed on ladder of the utility model.Wherein link up with the hook 3 of bar lower end for hanging weight, as paint or water etc.Wherein, hook 1 can be more firm if formed by suspension rod bent upon itself.

As illustrated in fig. 1 and 2, described suspension rod is connected by structure of adjusting length 4 with hook bar.

The kind of ladder is a lot, distance length between adjacent rungs is not identical, different ladders is widely used in order to the utility model can be made, also conveniently operate on the differing heights of same ladder, the utility model can regulate the collapsing length of suspension rod and hook bar according to need flexibly by design length adjustment structure 4, thus realizes regulating the spacing size of hook 3 and restriction protrusion 2 to be applicable to object on two crosspieces different apart from length.

As seen in figures 3-6, described structure of adjusting length 4 comprises the suspension rod adjusting portion 4.2 being positioned at suspension rod lower end, the hook bar adjusting portion 4.3 being positioned at hook bar upper end and locking piece 4.1, described suspension rod adjusting portion 4.2 is interval with multiple suspension rod adjustment hole 4.5 along suspension rod bearing of trend, and described hook bar adjusting portion 4.3 is interval with multiple hook bar adjustment hole 4.4 along hook bar bearing of trend; Described locking piece 4.1 is with suspension rod adjusting portion 4.2 and links up with the threaded fastener 4.1 that bar adjusting portion 4.3 coordinates.

Suspension rod adjustment hole 4.5 in suspension rod adjusting portion 4.2 cooperatively interacts corresponding with the hook bar adjustment hole 4.4 in hook bar adjusting portion 4.3.Wherein threaded fastener 4.1 can be the locking piece 4.1 of screw and nut composition, and screw is through the suspension rod adjustment hole 4.5 cooperatively interacting corresponding and link up with bar adjustment hole 4.4 and fix with nut.Wherein length is fallen to save structure regulatory function and is achieved in the following ways: according to distance required between hook 3 and restriction protrusion 2, suspension rod or hook bar are moved to required distance along respective central axis direction, and making at least one pair of suspension rod adjustment hole 4.5 and hook bar adjustment hole 4.4 correspondence mutually, collaboration locking piece 4.1 is locked.Structure of adjusting length 4 also can adopt flower basket bolt structure.

As shown in Fig. 1,2 and 4, described restriction protrusion 2 forms V-shaped projection for bending inwards in the middle part of hook bar.

Restriction protrusion 2 is bent to form for hook bar, compared to more firm by being fixedly connected with mode as welding, snapping etc., avoiding restriction protrusion 2 and there is the potential risk dropping or rock.

The bending of described hook bar lower end makes hook 3 protruding.

As shown in Fig. 1,2 and 4, hook 3 is protruding, while being convenient to hang weight, making the weight of suspension and operating personal have certain distance, prevents weight and operating personal from colliding, destroy stability of the present utility model.

Described hook bar and suspension rod are hard metal material and make.

Use metallic material to make hook bar and suspension rod, make the utility model have reasonable intensity and toughness, increase safety factor of the present utility model and service life.

Application the utility model:

Hook 1 is hooked on the crosspiece of ladder, the distance suitable length making restriction protrusion 2 and hook 1 is regulated by structure of adjusting length 4, restriction protrusion 2 is made to lean lower surface at another crosspiece, suspension rod adjustment hole 4.5 and the mutual correspondence of hook bar adjustment hole 4.4 are convenient to screw pass, re-use nut to fix, after weight is hung on hook 3.
