Description

Suspension hook with blocking device

Technical field

The utility model relates to a kind of crane hooks more particularly to a kind of with preventing the device that load falls off unintentionally Suspension hook.

Background technique

Currently, the suspension hook with blocking device, locking principle is as shown in Figure 1, blocking device 1 ' is mounted on by pin shaft 3 ' hangs On hook ontology 4 ', in use, squeezing blocking device 1 ' inwards by suspender belt, open the mouth of hook 41 ', suspender belt enters in the mouth of hook 41 ', But when suspender belt is larger, the suspender belt in the mouth of hook 41 ' can stop the rebound of blocking device 1 ', make it that can not close the mouth of hook 41 ', it is difficult to Anti-off effect is played to suspender belt.

Utility model content

The purpose of this utility model, which is that, solves the rebound that suspender belt stops blocking device, ask the mouth of hook can not closed Topic.

A kind of suspension hook with blocking device, including hook body, the hook body are equipped with the mouth of hook, are mounted on suspension hook sheet Pin shaft on body, the cross axle sleeve being sleeved on pin shaft, the blocking device being mounted in cross axle sleeve.

Suspension hook of the utility model with blocking device, wherein being separately mounted to pin shaft there are two the cross axle sleeves Rear and front end.

Suspension hook of the utility model with blocking device, wherein the blocking device is the structure of frame type.

Suspension hook of the utility model with blocking device, wherein the mouth of hook is arc-shaped greater than 270 °, and its upper surface For rough surface.

Have the technical effect that suspension hook of the utility model with blocking device is filled by the locking being mounted in cross axle sleeve The problem of up and down motion set controls the opening and closing of the mouth of hook, is not in blocking of the blocking device by suspender belt, can not close the mouth of hook.

There are the arc-shaped mouth of hook greater than 270 °, the mouth of hook in the suspension hook of suspension hook of the utility model with blocking device For rough surface, the cross axle sleeve can be rotated around pin shaft, realize the mouth of hook by the frictional force between blocking device and the mouth of hook Locking closure.

The suspension hook with blocking device of the utility model is described further with reference to the accompanying drawing.

Specific embodiment

As shown in Figures 2 and 3, suspension hook of the utility model with blocking device includes the hook body 4 of goat's horn type, suspension hook 1 Inside there is 300 ° of the arc-shaped mouth of hook 41, the upper surface of the mouth of hook 41 is coarse, and the right part of the mouth of hook 41 is fixedly installed with pin shaft 3, pin shaft 3 Rear and front end be respectively set with a cross axle sleeve 2 and cross axle sleeve 2 can be rotated around pin shaft 3, be mounted on two cross axle sleeves Frame type blocking device 1 in 2, and blocking device 1 can move up and down in cross axle sleeve 2, when the lower end of blocking device 1 is revolved When going to the left end of the mouth of hook 41, the effect of the frictional force between by hook body 4 and blocking device 1, blocking device 1 is locked at the position It sets, realizes the anticreep of suspender belt.

As shown in figure 4, pulling up blocking device 1, the mouth of hook 41 is i.e. openable, after suspender belt is caught in the mouth of hook 41, pushes down on Dynamic blocking device 1 can close the mouth of hook 41, and blocking device 1, which is rotated to the left end of the mouth of hook 41, locks, and solve suspender belt and stop locking The problem of device 1 is sprung back.

Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines In range.
