Abstract
The utility model discloses an adjustable spanner which is capable of fast moving. The utility model is characterized in that the internal of a spanner body is provided with a rapid driving mechanism; the rapid driving mechanism is composed of an active drive system and a driven transmission system; the connection between the systems is realized by the mesh of the active bevel gears and driven bevel gears; the side of the spanner body is provided with a sliding button arranged in a spiral groove of a driving sliding rod; the end part of the sliding rod is fixed on the active bevel gears; when the spanner is operated, the button is pushed and the sliding rod is rotated so that a worm is rotated, and thus, a movable mouth meshed with worm is driven to open and close.
Description
The utility model relates to a kind of spanner, exactly relates to the monkey wrench that a kind of jaw can be rapidly opened and closed.
Use now general monkey wrench, the switching of jaw realizes by the continuous rubbing worm thread of thumb fully, effort, time-consuming, work efficiency is low.
The utility model purpose is just can effectively open and close the plug-type monkey wrench of jaw fast for the user provides a kind of once-through operation.
The utility model is made up of wrench body, moving jaw, fast driving mechanism and four parts of cover plate.
Wrench body is the solid forging part, and its head front end is a regular jaw, and head side and shank one side have notch, hold moving jaw and fast driving mechanism respectively.And have the double offset ring spanner hole at the handle tail.
The moving jaw of spanner is a forge piece, and the part in the wrench body head groove of packing into is carved with oblique tooth bar.
The fast driving mechanism of spanner is made of active drive and two mechanisms of driven transmission, is loaded in the wrench body by notch.
Active drive mechanism includes slide bar, driving bevel gear, elastic ring, button, packing ring and the pin of band spiral, all is contained in the side channel of wrench body shank.Spiral slide bar one end is fixed in the slotted eye of the rectangular cover plate back side one end, and the other end is inserted in elastic ring and supports slide bar to prevent play, the then affixed driving bevel gear in termination.The pin of button back cushion circle and riveted joint is stuck in the helicla flute of slide bar, pushes away with thumb during operation or draws this button, and slide bar rotates immediately, drives the driving bevel gear rotation.
Slave hand actuator then installs in the side channel of wrench body head, includes driven bevel pinion, worm screw, spring, pin and plug screw.Worm screw one end by spring, sell, be fixed in the notch of wrench body crown circular-hole internal-wall, the other end then is hinged with on driven bevel pinion, and driven bevel pinion is meshed with driving bevel gear on the spiral slide bar.When the active drive system rotates, driven the driven bevel pinion rotation, because the oblique tooth bar engagement of spiral groove gear on the worm screw and moving jaw is directed at moving jaw to the rotation that makes worm screw and opens and closes along the actinal surface of wrench apace under thumb promotes.
Have long-range bar shaped notch on the cover plate, button of device can be free to slide along notch on it, and the cover plate back side one end has the usefulness of little slotted eye with fixed slip bar.On the bar shaped side channel that cover plate is covered at the wrench body shank, screw can make itself and wrench body be fixed as integral body.
Of the present utility model being characterised in that has the fast driving mechanism that is made of active drive and two mechanisms of driven transmission on the structure.
Advantage of the present utility model is, the ingenious design of fast driving mechanism has changed the conventional ADS driving mode of monkey wrench, and is not only laborsaving, and has shortened the switching time of jaw of spanner greatly, has improved operating efficiency.
The utility model has provided fast moving adjustable wrench generalized section.
1 is wrench body among the figure, and 2 is the regular jaw on the wrench body, and 3 is moving jaw, 4 is the spiral slide bar, and 5 is driving bevel gear, and 6 is elastic ring, 7 is button, and 8 is pin, and 9 is driven bevel pinion, 10 is worm screw, and 11 is spring, and 12 is pin, 13 is the plug screw, and 14 is cover plate, and 15 is screw, 16 is the double offset ring spanner hole, and 17 is the bar shaped notch that has on the cover plate.
Operation principle of the present utility model is as follows:
When the monkey wrench jaw is in closure state and need opens, pulling back button 7 with thumb moves along bar shaped notch 17 straight lines of cover plate 14, the slide bar 4 that pin 8 in the button 7 drives big helical pitch is done counter rotation, be fixed on driving bevel gear 5 on the slide bar 4 and drive driven bevel pinion 9 by engagement and clockwise rotate motion, so worm screw 10 has driven with the moving jaw 3 of its engagement along the actinal surface of spanner to opening the direction fast moving together with worm screw 10.Otherwise, when need be with the jaw of spanner closed, only need button 7 is pushed ahead fast and get final product with thumb.
Embodiment: the utility model is made of 14 parts, and wherein wrench body, elastic ring, jaw pin are forge piece; Worm screw, slide bar, galvanized screw, packing ring, screw plug, button are workpiece; Driving and driven bevel gear is the die carter engineering plastics, and cover plate is a precision castings, and spring is by manual coiling.The utility model is 200 * 24 types, that is: the long 200mm of body, jaw maximum opening 24mm.
