Abstract
The invention discloses an active nut liner, which comprises the following parts: liner host (1), inclined stony adjustment helicoid (3), mobile adjustment paw (5) and return spring (6), wherein the square groove (2) is opened in the middle of upper end face of liner host (1); the peripheral surface of column liner connects the inclined stony adjustment helicoid through screw; at least three mobile adjustment jaws are connected the end of inclined stony adjustment helicoid, which contains a limit jaw and return spring. The invention is fit for different standards of nut liner, which contains standard and non-standard norms.
Description
[technical field]
The invention relates to a kind of specific purpose tool, especially can be suitable for the sleeve of different size nut.And comprise metric and English specification and non-standard specification.
[background technology]
At present, existing adjustable movable sleeve, comprise collet head and the socket bar that combines as a whole with it, radially offer six T type grooves at the collet head end face, and six T type grooves are evenly arranged on the collet head end face, be provided with slide block and be slidingly matched with it in T type groove, be fixed with hornblock on slide block, six hornblocks constitute the hexagonal ring that a hexagon is interrupted; Socket bar is provided with screw thread, moves to be screwed on the socket bar by this screw thread soon, offers cannelure on the movable block periphery, is with change in it, and the change piece that can relatively move rotates around the movable block axial line; Offer through hole at collet head T type trench bottom, connecting rod pass this through hole one end and slide block hinged, the other end and change are hinged.The hexagonal ring that the hexagon that six hornblocks in the tube-in-tube structure constitute is interrupted and is rotated the hexagonal (hexagon)nut coupling, and after hexagonal (hexagon)nut was entangled, the rotational sleeve bar was promptly detachable and tighten this hexagonal (hexagon)nut.Rotation is screwed in the movable block on the socket bar, drives six slide blocks by connecting rod and slides along T type groove, thereby change the hexagonal ring size that six hornblocks constitute, to adapt to the hexagonal (hexagon)nut of different size.But this sleeve can't be suitable for metric and English specification and non-standard specification.Can not be suitable for all nuts.
[summary of the invention]
The purpose of the invention is the adjustable sleeve that a kind of novel structure is provided according to mechanics and theory of mechanics, can be used in different size nut dismounting and tighten, and comprise that metric and English specification and non-standard specification all can be general.
For achieving the above object, design a kind of screw cap adjustable bushing, comprise that sleeve body (1), oblique stone are regulated bung flange (3), pawl (5), return spring (6) are regulated in activity, sleeve body (1) middle part, upper surface has square groove (2), it is characterized in that cylinder sleeve peripheral surface adopts the oblique stone that is threaded to regulate bung flange, regulate the bung flange end at oblique stone and connect movable adjusting pawl more than at least three, movable adjusting pawl is provided with a position-limited claw, and movable the adjusting on the pawl is connected with return spring.
After in the square groove on the sleeve connection square plug cover tube main body of special use, just can regulate oblique stone and regulate bung flange this moment, make oblique stone regulate bung flange and advance along regulating threads turn, the oblique stone that oblique stone is regulated on the bung flange pushes away movable adjusting pawl top to the contraction of the center of sleeve.Make it keep a firm hand on nut and reach the condition purpose.Just can pull nut this moment.Otherwise tiltedly stone is regulated bung flange and is stepped back (setback promptly makes progress), and under the return spring effect, movable adjusting pawl withdraws from part outside sleeve body makes it can firmly grasp bigger nut.Position-limited claw mainly is to place restrictions on the movable pawl of regulating to the usefulness that designs nut specification position.
The invention compared with prior art, novel structure, easy to use, be not subjected to the limitation of specification, and in behind binding nut from trivial, do not need the very big power of holding to hold with a firm grip, in use can be in setting range the regulated at will openings of sizes.The manufacturing of this sleeve is simple in addition, and cost is low, and is sturdy and durable, practical, is worthy of promotion and application.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Referring to Fig. 1, Fig. 2,1 is sleeve body, and 2 is square groove, and 3 is that oblique stone is regulated bung flange, and 4 for regulating screw thread, and 5 is the movable pawl of regulating, and 6 is return spring, and 7 is position-limited claw.
[specific embodiment]
Shown in Figure 2 as Fig. 1, center, sleeve body top offers a main body square hole, and cylinder sleeve peripheral surface adopts the oblique stone that is threaded to regulate bung flange, regulates terminal four activities that evenly distribute of bung flange at oblique stone and regulates pawls.There is a position-limited claw on each movable pawl side of regulating.Below sleeve, be provided with a cylindrical aperture, in the hole, be provided with a return spring, and the movable pawls of regulating of return spring and four link.
During use, rotate oblique stone and regulate bung flange, make oblique stone regulate bung flange and advance along regulating threads turn, the oblique stone that oblique stone is regulated on the bung flange pushes away movable adjusting pawl top to the contraction of the center of sleeve.Make it keep a firm hand on nut and reach the condition purpose.Just can pull nut this moment.Otherwise tiltedly stone is regulated bung flange and is stepped back (setback promptly makes progress), and under the return spring effect, movable adjusting pawl withdraws from part outside sleeve body makes it can firmly grasp bigger nut.Position-limited claw mainly is to place restrictions on the movable pawl of regulating to the usefulness that designs nut specification position.
