Description
Technical field
The present invention relates to a kind of fastened tools.
Background technology
Tool sleeve inner chamber fastening is at present interior hexagon.When carrying out fastened by screw operation, nut and spring pad can only be put into sleeve, circular flat packing ring cannot put into sleeve.When site operation is installed, when particularly upwards or obliquely upward carrying out fastened by screw operation, be difficult to circle plain washer to be fixed, during operation, plain washer easily comes off.Therefore very inconvenient, thus cause operating efficiency to reduce.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, propose a kind of new fastened by screw sleeve.
The present invention has following characteristics:
1, the decapacitation of sleeve Inner chamber is inserted in outside hex nut and spring washer, can also be inserted in circular flat packing ring equipped with it.
2, circular flat packing ring is pushed easily into sleeve, is namely blocked by special mechanism after being inserted in, and can not drop out sleeve, and clamping mechanism can not hinder clamp nut, and after fastening nuts, sleeve can be extracted out easily.
The technical solution used in the present invention is:
Be one section of round cavity before sleeve hexagon inner chamber, the diameter of round cavity slightly larger than the circular flat gasket diameters equipped with hex nut, in order to hold equipped circular flat packing ring; The circular outer wall of described round cavity section has annular groove near front end face place, and the width of groove is enough to clamp an annular jump ring.Described annular jump ring has opening, with can card fits into groove, has double wedge inside annular jump ring.In groove, middle part has the radial hole coordinated with the double wedge inside jump ring, and the double wedge inside jump ring gives prominence to round cavity surface a little, to block the circular flat packing ring be inserted in through aperture.The axial cross section shape that described double wedge gives prominence to round cavity surface portion is pointed shape, has symmetrical hypotenuse.
When pushing circular flat packing ring from the export-oriented Inner of sleeve, circular plain cushion contacts with jump ring double wedge, axial force imposes on described double wedge and gives prominence on the inclined-plane of round cavity surface portion, thus make jump ring be subject to the effect of a radial component and outwards open, the double wedge of jump ring is retreated, and circular plain cushion easily passes through jump ring and is pushed into sleeve Inner.When circular plain cushion is by after jump ring, the radial load that jump ring is subject to disappears, and the double wedge of jump ring is protruding again to be blocked circular plain cushion and make it not drop outward.When carrying out fastening nuts, nut produces axial force and pushes circular plain cushion from inside to outside from sleeve.In like manner, because the inclined-plane of jump ring double wedge produces radial component, jump ring is opened, double wedge retreats, until after fastening nuts, unhinderedly extracts sleeve out easily, and the radial load that jump ring is subject to disappears, and double wedge is protruding reset again.
The front section of barrel bore of the present invention is circular, and sleeve leading portion is equipped with jump ring, packing ring can be blocked, and solves the problem that packing ring easily drops when terminal operation, especially for in-site installation operation, can greatly improve work quality and efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Fig. 1 and Fig. 2 is structural representation of the present invention.As depicted in figs. 1 and 2, barrel bore of the present invention is vertically from barrel forward end towards inner, and order is round cavity and hexagon inner chamber.The cross section of round cavity is circular, and the cross section of hexagon inner chamber is interior hexagon.The axial length of round cavity section is 4 ~ 6mm.Round cavity section is communicated with hexagon inner chamber section, concentricity axle.Round cavity diameter, slightly larger than the circular flat gasket diameters equipped with hex nut, can hold the matching used circular plain cushion 4 with nut 1.The outer wall of round cavity section has annular groove 6 near front end face place, and groove 6 starts from the 1-2mm place in distance barrel forward end face.The width of the width gap of groove 6 can clamp an annular jump ring 3.Middle part in described groove 6 has the hole of the radial direction coordinated with the double wedge inside jump ring, there is double wedge 5 the Inner side of annular jump ring 3, and double wedge 5 is through the aperture of groove 6, and the circular Inner chamber of outstanding sleeve is a little, in order to block the circular plain cushion 4 be inserted in, circular plain cushion 4 is not dropped.The axial cross section shape that described double wedge gives prominence to round cavity surface portion is pointed shape, has symmetrical hypotenuse.
The interior hexagonal section section of sleeve mainly plays the role of fastening.
Figure 3 shows that annular jump ring 3.The inner side of annular jump ring 3 is evenly equipped with three double wedges 5, and the axial cross section shape that double wedge 5 gives prominence to round cavity surface portion is pointed shape, has symmetrical hypotenuse.Described annular jump ring 3 has opening, with can card fits into groove 6.
The screw and nut that the present invention is directed to different model has different model sleeves, the nut of different model can be selected to carry out fastening in operation.
As shown in Figure 4, when carrying out terminal operation, first the nut 1 of respective model, spring washer 2 and circular plain cushion 4 are put into barrel bore, then circular flat packing ring 4 is pushed from the export-oriented Inner of sleeve, circular plain cushion 4 is contacted with the double wedge 5 of jump ring 3, the double wedge 5 of jump ring 3 retreats, and circular plain cushion 4 easily passes through jump ring 3 and is pushed into sleeve Inner.After circular plain cushion 4 passes through jump ring 3, jump ring, the double wedge 5 of 3 is protruding again, blocks circular flat pad and makes it not drop outward; When carrying out fastening nuts, nut 1 produces axial force and pushes circular plain cushion 4 from inside to outside from sleeve.Because the inclined-plane of the double wedge 5 of jump ring 3 produces radial component, jump ring 3 is opened, and double wedge 5 retreats, until nut 1 fastening after, unhinderedly extract sleeve out easily, radial load that jump ring 3 is subject to disappears, and double wedge 5 is protruding reset again.
The present invention also can be used as ordinary cartridge and uses.
The present invention fully takes into account the impact that working environment causes user, need not worry that circular flat packing ring drops, thus enhance the practicality of sleeve, improve operating efficiency in operation.
