Description
Technical field
The present invention relates to a kind of fastened tools.
Background technology
Fastening tool sleeve inner chamber is interior hexagon at present.When carrying out the fastened by screw operation, nut and spring pad can only be put into sleeve, the circular flat packing ring can't be put into sleeve.When site operation is installed, particularly upwards or when carrying out the fastened by screw operation obliquely upward, be difficult to the circle plain washer is fixed, plain washer comes off easily during operation.Therefore very inconvenient, thus cause operating efficiency to reduce.
Summary of the invention
The objective 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 the spring washer, can also be inserted in equipped with it circular flat packing ring.
2, the circular flat packing ring is urged 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 behind the fastening nuts, sleeve can be extracted out easily.
The technical solution used in the present invention is:
Be one section round cavity in the front of sleeve hexagon inner chamber, the slightly larger in diameter of round cavity is in the circular diameter of plain washer equipped with hex nut, in order to hold equipped circular flat packing ring; Have annular groove near the front end face place on the circular outer wall of described round cavity section, the width of groove is enough to clamp an annular jump ring.Described annular jump ring has opening, and can clamp into groove, there is double wedge annular jump ring inboard.The middle part has the radial hole that cooperates with the double wedge of jump ring inboard in the groove, the double wedge of jump ring inboard pass the outstanding round cavity of aperture surperficial a little, in order to block the circular flat packing ring that is inserted in.The axial cross section of the outstanding round cavity surface portion of described double wedge is shaped as pointed shape, and symmetrical hypotenuse is arranged.
When from the export-oriented Inner pushing of sleeve circular flat packing ring, circular plain cushion contacts with the jump ring double wedge, axial force imposes on the inclined-plane of the outstanding round cavity surface portion of described double wedge, thereby 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 is pushed into sleeve Inner by jump ring easily.When circular plain cushion by behind the jump ring, the radial load that jump ring is subject to disappears, the double wedge of jump ring is protruding again to be blocked circular plain cushion and makes it not drop outward.When carrying out fastening nuts, nut produces axial force and pushes from inside to outside circular plain cushion 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 behind the fastening nuts, unhinderedly extract easily sleeve out, the radial load that jump ring is subject to disappears, and double wedge is protruding resetting again.
The leading portion of barrel bore of the present invention partly is circular, and the sleeve leading portion is equipped with jump ring, packing ring can be blocked, and has solved the problem that packing ring easily drops when terminal operation, especially for on-the-spot installation exercise, can greatly improve work quality and efficient.

1 nut among the figure, 2 spring washers, 3 annular jump rings, 4 circular plain cushions, 5 double wedges, 6 grooves.
The specific embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Fig. 1 and Fig. 2 are 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 and hexagon inner chamber section are communicated with, concentricity axle.The round cavity slightly larger in diameter can be held and nut 1 matching used circular plain cushion 4 in the circular diameter of plain washer equipped with hex nut.Have annular groove 6 near the front end face place on the outer wall of round cavity section, groove 6 starts from the 1-2mm place apart from the barrel forward end face.The width of the width groove of groove 6 can clamp an annular jump ring 3.Middle part in the described groove 6 has the hole radially that cooperates with the double wedge of jump ring inboard, the Inner side of annular jump ring 3 has double wedge 5, and double wedge 5 passes the aperture of groove 6, the circular Inner of outstanding sleeve chamber a little, in order to block the circular plain cushion 4 that is inserted in, circular plain cushion 4 is not dropped.The axial cross section of the outstanding round cavity surface portion of described double wedge is shaped as pointed shape, and symmetrical hypotenuse is arranged.
The interior hexagonal section section of sleeve mainly plays the role of fastening.
Figure 3 shows that annular jump ring 3.The inboard of annular jump ring 3 is evenly equipped with three double wedges 5, and the axial cross section of double wedge 5 outstanding round cavity surface portions is shaped as pointed shape, and symmetrical hypotenuse is arranged.Described annular jump ring 3 has opening, can clamp into groove 6.
The screw and nut that the present invention is directed to different model has different model sleeves, can select the nut of different model to carry out fastening in the operation.
As shown in Figure 4, when carrying out terminal operation, at first nut 1, spring washer 2 and the circular plain cushion 4 of respective model are put into barrel bore, then from the export-oriented Inner pushing of sleeve circular flat packing ring 4, 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 is pushed into sleeve Inner by jump ring 3 easily.After circular plain cushion 4 passes through jump ring 3, jump ring, 3 double wedge 5 is protruding again, blocks the circular flat pad and makes it not drop outward; When carrying out fastening nuts, nut 1 produces axial force and pushes from inside to outside circular plain cushion 4 from sleeve.Because the inclined-plane of the double wedge 5 of jump ring 3 produces radial component, and jump ring 3 is opened, double wedge 5 retreats, until nut 1 fastening after, unhinderedly extract easily sleeve out, the radial load that jump ring 3 is subject to disappears, double wedge 5 is protruding resetting 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 the user, needn't worry in the operation that the circular flat packing ring drops, thereby strengthen the practicality of sleeve, has improved operating efficiency.
