Abstract
The invention discloses a kind of multi-claw hook, comprise suspension bracket and be connected some chain slings on the suspension bracket, described at least one chain sling is provided with extension adjustment device, described chain sling comprises serobila and hook, hook is connected on the serobila by extension adjustment device, and described extension adjustment device comprises connector, and middle part, described connector two ends is provided with internal thread hole, described serobila and hook end are equipped with threaded joints, and serobila and hook are connected by the screw thread gaily decorated basket with connector.The serobila that the present invention will have common chain sling now is improved to the internal and external threads gaily decorated basket with the connection structure of hook and is connected, length and orientation angle can both be adjusted arbitrarily, thereby various liftings have been made things convenient for be uneven position and multi-aspect object towards joint hinge, simple in structure, easy to use, improved lifting efficient.
Description
Technical field
The present invention relates to multi-claw hook.
Background technology
In the process of producing product of all trades and professions, often need use multi-claw hook, as the sand core of in foundry goods is made, using, just need to adopt multi-claw hook that it is lifted the into inside of external mold, because the joint hinge position on the loam core is " agitated " very fitfull, as Fig. 1, the length of existing multi-claw hook serobila 1 and hook 2 is identical, run into during use be uneven or multi-aspect towards joint hinge, just can only connect with iron wire or rope temporarily, very inconvenience.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of multi-claw hook simple in structure, can solve in lifting and have when being uneven position and multi-aspect object towards joint hinge, adopt existing multi-claw hook to connect, very Bu Bian deficiency with iron wire or rope temporarily.
In order to solve the problems of the technologies described above, the present invention adopts following technology side to decide on a verdict: a kind of multi-claw hook comprises suspension bracket and is connected some chain slings on the suspension bracket that it is characterized in that: described at least one chain sling is provided with extension adjustment device.
Preferably, described chain sling comprises serobila and hook, and described hook is connected on the serobila by extension adjustment device.
Preferably, all be provided with extension adjustment device on the described every chain sling.
Preferably, described extension adjustment device comprises connector, and middle part, described connector two ends is provided with internal thread hole, and described chain end of body is provided with threaded joints, and serobila is spent blue the connection with connector by screw thread.
Further, described hook end is provided with threaded joints, and hook is spent blue the connection with connector by screw thread.
Preferably, described chain sling is 3～8.
The present invention is owing to adopt technique scheme, the serobila of existing common chain sling is improved to internal and external threads with the connection structure of hook spends orchid to be connected, length and orientation angle can both be adjusted arbitrarily, thereby various liftings have been made things convenient for be uneven position and multi-aspect object towards joint hinge, simple in structure, easy to use, improved lifting efficient.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of existing multi-claw hook;
Fig. 2 is the structural representation of multi-claw hook of the present invention;
Fig. 3 is an I place enlarged drawing among Fig. 2.
The specific embodiment
As shown in Figure 2, be a kind of multi-claw hook of the present invention, comprise suspension bracket 3 and be connected three chain slings on the suspension bracket, every chain sling is provided with extension adjustment device, and described chain sling comprises serobila 1 and hook 2, and described hook is connected on the serobila by extension adjustment device, described extension adjustment device comprises connector 4, middle part, described connector 4 two ends is provided with internal thread hole 41, and described serobila and hook end are equipped with threaded joints 42, and serobila 1 and hook 2 are spent blue the connection with connector 4 by screw thread.
The present invention is owing to adopt technique scheme, the serobila of existing common chain sling is improved to internal and external threads with the connection structure of hook spends orchid to be connected, length and orientation angle can both be adjusted arbitrarily, thereby various liftings have been made things convenient for be uneven position and multi-aspect object towards joint hinge, simple in structure, easy to use, improved lifting efficient.
