Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
nullRefer to Fig. 1 to Fig. 4，A kind of wrench assembly with strengthening annulus of this utility model one preferred embodiment，It includes spanner 10、Inserting column 20 and connecting rod 30，This inserting column 20 is hollow structure，Spanner 10 is installed in rotationally and is available for staff on the outer wall of water tank wall and pulls，Inserting column 20 is installed in the side of spanner 10，The present embodiment adopts inserting column 20 to make with spanner 10 is one-body molded，One end of connecting rod 30 has linkage section 32，Linkage section 32 inserts from the outer end 22 of inserting column 20 in inserting column 20 and coordinates circumferencial direction is spacing with inserting column 20，Rotating spanner 10 is rotated by inserting column 20 drivening rod 30，The internal diameter of the external diameter of linkage section 32 and inserting column 20 matches，The outer wall of inserting column outer end 22 is also arranged with one in order to strengthen the annulus 40 of the intensity of inserting column outer end 22，Preferably the outer wall of the inwall of annulus 40 Yu inserting column outer end 22 is designed as interference fit，Such annulus 40 is better to the stiffening effect of the intensity of inserting column outer end 22，The inwall of certain annulus 40 and the outer wall of inserting column outer end 22 may be designed in interference fits，Equally also can reach the purpose of this utility model.
In the present embodiment, it is installed on the outer wall of inserting column outer end 22 after the independent molding of annulus 40, tool during attaching, can be used to be knocked on the outer wall of inserting column outer end 22 by annulus 40.
In the present embodiment, the inward flange 42 of annulus 40 end is provided with chamfering, annulus 40 so can be made to be easier to be inserted in the outer wall of inserting column outer end 22, to improve efficiency of assembling.
In the present embodiment, the retaining convex rib (not shown) axially extended it is provided with at inserting column 20 inwall, connecting rod 30 inserts the linkage section 32 of inserting column 20 part and is correspondingly provided with the limited impression 34 axially extended, coordinated by retaining convex rib and limited impression 34 spacing and realize connecting rod 30 and coordinate the spacing of circumferencial direction with inserting column 20, certainly, understandable, can also be provided with, at inserting column 20 inwall, the limited impression axially extended, and the linkage section 32 that correspondence inserts inserting column 20 part at connecting rod 30 is provided with the retaining convex rib axially extended, its effect is equivalent.
The material of annulus 40 can be metal or plastics, the such as engineering plastics such as stainless steel or ABS, is not limited system, of course for saving cost, adopts plastic material, and when the material of annulus 40 is plastics, the wall thickness of annulus 40 is preferably greater than 1.5mm；When the material of annulus 40 is metal, the wall thickness of annulus 40 is preferably greater than 1mm.
As shown in Figure 4, the preferred annulus 40 of the present embodiment length L vertically is not less than 1mm, the present embodiment L value 3mm, and such stiffening effect is better, and the wrench assembly life-span is longer.
Additionally, edge, inserting column outer end 22 is preferably placed in annulus 40 or the outer end edges flush of edge, inserting column outer end 22 and annulus 40.
In the present embodiment, also include fastening assembly 50, fastening assembly 50 includes the screw head 51 and the nut 52 that are fixed on water tank wall installing hole (not shown) place by threaded engagement, screw head 51 has threaded hollow structure for outer wall, inserting column 20 is arranged in after the outer end 22 of screw head 51 and inserting column 20 passes this screw head 51 to coordinate with annulus 40 socket, the external diameter of annulus 40 internal diameter more than screw head 51 and the internal diameter less than nut 52, owing to the external diameter of annulus 40 is more than the internal diameter of screw head 51, such annulus 40 also acts position-limiting action, to prevent inserting column 20 from deviating from from screw head 51, and owing to the external diameter of annulus 40 is less than the internal diameter of nut 52, thus not affecting this annulus 40 of nut 52 traverse and screw head 51 threaded engagement when annulus 40 is set in inserting column outer end 22.By the fastening assembly 50 of screw head 51 and nut 52 composition, wrench assembly is fixed on the installing hole place of water tank wall, simple in construction, it is firm to connect, can certainly adopt other fastening means that wrench assembly is fixed on the installing hole place of water tank wall, mode as by clamping is also feasible, is not explained in detail here.
During assembling, first by inserting column 20 traverse screw head 51, screw head 51 is exposed in the outer end 22 of inserting column 20, with tool, annulus 40 is knocked in the outer end 22 of inserting column 20, make it be enclosed within the outer wall of inserting column outer end 22 and with the outer wall interference fit of inserting column outer end 22, the retaining convex rib that limited impression 34 on the linkage section 32 of connecting rod 30 one end is directed at inserting column 20 inwall subsequently inserts, connecting rod 30 is fixed in inserting column 20, thus when spanner 10 stress is pulled and rotated with drivening rod 30, owing to the booster action of annulus 40 makes the outer end 22 not easily stress cracking of inserting column 20, thus ensure that the intensity of inserting column 20, the life-span making whole wrench assembly lengthens.
Refer to Fig. 5, Fig. 5 depicts a kind of wrench assembly with strengthening annulus of another preferred embodiment of this utility model, itself and above-described embodiment are distinctive in that, annulus 40 is one-body molded on connecting rod 30, and the linkage section 32 of connecting rod 30 one end inserts inserting column 20 when putting in place from inserting column outer end 22, and annulus 40 is socketed with the outer wall of inserting column outer end 22 and coordinates, such it is advantageous in that, annulus 40 is not independent part, it is not easy to lose, and the operation that annulus 40 is socketed in inserting column outer end 22 is more prone to and laborsaving.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; in the form and details this utility model is made a variety of changes, be protection domain of the present utility model.
