Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1, the embodiment of the present invention mainly comprises sleeve, internal gear 2, handle 4, and preferably, sleeve is two-part structure, comprises epimere 1 all cylindrically, hypomere 4.
Specifically, sleeve entirety is in tubular, the interior wall construction 41 of its hypomere 4 coincide (as shown in Figure 8, Figure 9) with head 101 structure of bolt 100, to be set in the head 101 of bolt 100 closely, the head of such as bolt is hexagon head structure, then the interior wall construction of sleeve hypomere is also hexagon head structure.The outer wall of epimere 1 is provided with along the circumferential direction equally distributed teeth groove 11, and the quantity of teeth groove is multiple, and in figure 3, the quantity of teeth groove is 12.The sleeve of the present embodiment is divided into epimere 1, hypomere 4, and especially, the epimere 1 being provided with teeth groove 11 shrinks, and external diameter diminishes, namely the external diameter of epimere is less than the external diameter of hypomere, so has multiple advantages, and such as manufacturing process is simple, avoid interfering, preferably, the internal diameter of epimere is less than the internal diameter of segment.
More preferably, as shown in Figure 2 and Figure 3, the upper surface of hypomere 4 is closed, and epimere 1 fixing (such as welding) is on this closed upper end face of hypomere 4.Epimere 1 comprises cylindrical shell 12 and the cover plate 13 for closing its upper surface, thus makes epimere 1 inside in hollow shape, alleviates the weight of sleeve, is beneficial to operation.
The outer wall that teeth groove 11 is positioned at cylindrical shell 12 is connected with the upper surface of hypomere 4, so can improves the bonding strength of teeth groove 11 and hypomere.
As shown in Figure 4, Figure 5 and Figure 6, internal gear 2 is in circular, and comprise ring body 21, internal tooth 23, ring body 21 inwall arranges an internal tooth 23.During application, internal gear 2 is set in outside sleeve epimere 1, and internal tooth 23 embeds teeth groove 11, and teeth groove 11 engages.Internal tooth 23 is only one, and structure is simple, is convenient to manufacture, operate.The shape of internal tooth 23 is preferably trapezoidal, and the shape of teeth groove 11 is also trapezoidal for what be meshed with internal tooth.
As shown in Figure 7, handle 3 is in shaft-like, and one end is fixed on internal gear 2, rotates for driving internal gear 2.Again as shown in Figure 4, the sidewall of internal gear 2 is provided with screw 22, and one end of handle 3 is provided with screw thread 31, and this end being provided with screw thread 31 of handle 3 inserts in screw 22.Preferably, on internal gear 2, the setting position of screw 22 is corresponding with the setting position of internal tooth 23.
The present embodiment can be applied to multiple bolt specification, such as bolt specification M8-M24 etc.
When applying, can with reference to following operating procedure:
As shown in Figure 8, be placed on by the hypomere 4 of sleeve on the head 101 of the fastening or loosening bolt 100 of needs, handle 3 is connected with internal gear 2, is enclosed within the epimere 1 of sleeve.
After handle 3 drives internal gear 2 to turn an angle, carry (as Fig. 9), rotate backward certain angle simultaneously, then put down on internal gear 2, internal tooth 23 engages with the teeth groove 11 of epimere 1 outer wall again, now, can carry out secondary rotation.
To sum up, the invention provides a kind of operation tool being applicable to narrow space bolted and dismounting, comprise sleeve, internal gear, handle, utilize gears meshing operation principle, engaged by internal gear internal tooth with teeth groove, band moving sleeve rotates, and sleeve drives screws.Visible, the present invention can solve the problem that small space inner bolt loosens, installs difficulty, avoids, because of threaded pre-tightening power the equipment operation irregularity caused not and the possibility producing fault, improving the reliability of equipment, improving the operating efficiency of equipment.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
