Description

Hex bolts pulling off sleeves

Technical field

The utility model belongs to mechanical dismantling device field, specifically a kind of hex bolts pulling off sleeves.

Background technique

Bolt is in electronic product, engineering goods, digital product, power equipment, electromechanical engineering goods, ship, vehicle, water conservancy Engineering etc. is with extensive.It is not that have corroded be exactly to skid in real life after the long experience exposing to the weather of bolt, Cause disassembly difficult, causes great inconvenience to maintenance work.Common removing method mainly have " burning ", " punching ", " weldering ", Use pipe wrench or hydraulic tongs etc.." burning " will increase the fit clearance of screw thread pair, reduce frictional force, but be likely to result in machine Local deformation damage；" punching " replaces skidding nut with V-shaped groove, when working expenditure, laborious；" weldering " replaces skidding nut with iron block, but Connector is easily broken；Can strongly it be back-outed using pipe wrench, hydraulic tongs, but limited working space.

In summary, still lack the reply simple, fast device or method of bolt slippage problems at present.

Based on this, this case application is proposed.

Summary of the invention

To solve the problems, such as that hex bolts gets rusty in the prior art, skidding and be difficult to back-out, the utility model provides one Kind can easily unscrew the device of bolt when hex bolts skids and corrodes, and the bolt difficulty for solving to get rusty is unscrewed, bolt skids The problem of can not unscrewing.

To achieve the above object, the scheme that the utility model uses is as follows: hex bolts pulling off sleeves, including sleeve sheet Body, sleeve body are to offer from bottom and slot, and are offered at the top of the top of lower fluting, sleeve by means of power rod aperture.Part Lower fluting is the erose fixation alveolus of row's triangle.The side of the sleeve body of the fixed alveolus of face offers screw hole, spiral shell Hole is connected to lower fluting, and the inside of screw hole is screwed with a mandril screw.

The utility model is further provided that the shape that the cross section of lower fluting is closed in camber line and row's shaggy tooth knot Shape.

The utility model is further provided that the bottom of mandril screw is tip, top is triangular shape, four horn shapes, five Horn shape, it is hexagonal in it is any.

The utility model is further provided that described to borrow power rod aperture be shape is polygonal fluting.

The utility model is further provided that groove depth is 0.5 ~ 2cm.

The utility model is further provided that lower groove depth is 1.5 ~ 3cm.

The utility model is further provided that the lower fluting diameter is 2.5 ~ 5cm.

The utility model technical effect is as follows: sleeve need to only be covered on hex bolts and be tightened when dismantling by the utility model After sleeve is fixedly connected by mandril screw with hex bolts, then with tool by slotting sleeve drive hex bolts rotation Disassembly is completed, it is especially difficult in the case where twisting narrow space or the deeper operating condition of recess to overcome because hex bolts gets rusty, skids The problem of to back-out.

The utility model size is close with ordinary cartridge, therefore compact, light, and easy to carry, production cost is low.And And overall structure is threadedly coupled, structure is simple mainly using fluting, aperture design only with simple.By means of power rod aperture and commonly Sleeve borrows power rod aperture size to be unanimously easy to use.

As shown in the figure: 1-sleeve body, 101-borrow power rod aperture, 102-lower flutings, 102a-fixation alveolus, 103-spiral shells Hole, 2-mandril screws, 201-heads, 202-bottoms.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

Embodiment 1

As shown in Figure 1, hex bolts pulling off sleeves, including sleeve body 1,1 bottom of sleeve body offer lower fluting 102,102 depth of lower fluting are 1.5 ~ 3cm, diameter is 2.5 ~ 5cm.The top of lower fluting 102 is offered by means of power at the top of sleeve Rod aperture 101.It is shape by means of power rod aperture 101 is rectangular fluting in the present embodiment, groove depth is 0.5 ~ 2cm, and diameter/size is Common-use size.

As shown in connection with fig. 2, the lower fluting 102 of the present embodiment 2/3 is circular trough, and residue 1/3 is in triangle shaggy tooth for a row The fixation alveolus 102a of shape.As shown in figure 3, the shape that the cross section of lower fluting 102 is closed in camber line and row's shaggy tooth knot.

The side of the sleeve body 1 of the fixed alveolus 102a of face offers screw hole 103, and screw hole 103 and lower fluting 102 connect Logical, the inside of screw hole 103 is screwed with a mandril screw 2.The bottom 202 of mandril screw 2 is tip, top is triangular shape, quadrangle Any one of shape, five-cornuted, hexagonal, the head 201 of mandril screw 2 uses turret head in the present embodiment.

The present embodiment is used referring to Fig. 4, is got rusty by slotting for the present embodiment sleeve body 1 to be nested with greatly to be unscrewed Or on the hex nut to skid, then mandril screw 2 screwed in from the screw hole 103 of side know mandril screw 2 by getting rusty or The hex nut of skidding withstands and is fixed in sleeve body 1.Then, general spanner is reused to be inserted by means of power rod aperture 101 In after rotating spanner hex nut get rusty or skidding can be driven to rotate together.

Embodiment 2

The present embodiment difference from example 1 is that: the present embodiment borrow power rod aperture 101 at be directly fixedly connected with one The swing handle of L shape or T shape.

Based on above-mentioned, the utility model provides a kind of hexagonal sieve double-purpose provision for disengagement that structure is simple, easy to use, First with hex nut itself there is smooth side to be bonded with the plane where fixed alveolus 102a --- to six to get rusty Position of the angle nut in sleeve is tentatively limited, and is reused mandril and is withstood --- further to the hex nut to get rusty Position in sleeve is defined, and by the alveolus of the pointed tail portion of mandril and triangle double wedge shape, is improved and decided on a verdict, fix tooth Pressure of the slot 102a to the hex nut to get rusty, so that it is guaranteed that hex nut to be unscrewed can follow the rotation of sleeve and turn It is dynamic, realize the release of hex nut get rusty or skidding.Originally it is utility model compact, a certain range of six can be suitble to The use of angle nut, suitable for the various occasions for needing to unscrew hex nut.

As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature Scheme is applied to realize.Therefore, embodiment disclosed above, in all respects are merely illustrative, and are not only 's.All changes that come within the scope of the invention or equivalents of the invention are by the utility model packet Contain.
