Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
First embodiment:
As shown in accompanying drawing 1 ~ 5, the axially locating locking device described in first embodiment of the invention, comprises nut sleeve 3, and is threadedly connected to the locking nut 2 of nut sleeve 3.This axially locating locking device, for the synthesis of on wooden big-canopy framework 4, described nut sleeve 3 is arranged on big-canopy framework, and an axis connecting rod 1 is through multiple nut sleeve 3.
Described nut sleeve 3, in hollow shape, is passed for described axis connecting rod 1.Described nut sleeve 3 offers tensioning seam 31 vertically, and nut portions 33 radial direction is closed up, and after locking nut 2 is tightened, the elastic force that utilization is closed up makes to screw between screw thread and compresses, and prevents locking nut 2 from loosening.Described tensioning seam 31 is multiple, and multiple tensioning seam 31 is symmetricly set on described screw section 33, can make locking nut 2 uniform force like this, convenient installation, and locking effect is better.Described nut sleeve 3 comprises the shaft shoulder 32 and screw section 33 that lay respectively at its two ends, connects the insertion part 34 of the shaft shoulder 32 and screw section 33.The described shaft shoulder 32 is closely tied in described big-canopy framework 4 outer wall side, and described screw section 33 is provided projectingly on described big-canopy framework 4 outer wall opposite side, and described insertion part 34 is inserted in described big-canopy framework 4.Described screw section 33 is provided with outside thread, in order to lock nut 2.Front end, described screw section 33 is provided with the first tapered slope 35, contributes to locking nut 2 and tightens in process and be pressed on axis connecting rod 1 by locking nut 2.The described shaft shoulder 32 is one-body molded with described insertion part 34, and the described shaft shoulder 32 external diameter is greater than the external diameter of described insertion part 34, plays positioning action to make the shaft shoulder 32.
Described locking nut 2 is also in hollow shape, and have internal thread, this internal thread coordinates with the outside thread of described nut sleeve 3.The shaft shoulder 32 of described locking nut 2 and described nut sleeve 3 is closely tied in the opposite side of described big-canopy framework 4 outer wall respectively, can clamp described big-canopy framework 4 better like this.Described locking nut 2 inwall is provided with angle and is greater than with the first tapered slope 35 and the second tapered slope 21 of coordinating with it, contributes to closely cooperating of screw section 33 and axis connecting rod 1 when locking nut 2 is installed on nut sleeve 3.
Second embodiment, refer to accompanying drawing 6 ~ 7, the present embodiment and the first embodiment distinguish and are: the first tapered slope is omitted in front end, described screw section 33, but be provided with the first tapered thread 36 at described screw section 33 outer wall, described locking nut 2 inwall is provided with the second tapered thread (not shown), described first tapered thread 36 and the second tapered thread (not shown) coordinate, and make locking nut 2 more stubborn tighter on described screw section 33, thus make nut sleeve 3 and axis connecting rod 1 compact siro spinning technology.
3rd embodiment, please refer to accompanying drawing 8, and the present embodiment and the first embodiment distinguish and be:
When this axially locating locking device is used for non-synthetic wood rigidity big-canopy framework, can cause locking axis connecting rod and non-synthetic wood rigidity big-canopy framework because crossing positioning and locking simultaneously, in order to avoid crossing location, between described big-canopy framework 4 and locking nut 2, increase by a back of the body female 5.The described back of the body female 5 is threadedly connected to screw section 33; And the described back of the body female 5 and the described shaft shoulder 32 are closely tied in outside described big-canopy framework 4, after nut sleeve 3 and non-synthetic wood rigidity big-canopy framework being locked by the described shaft shoulder 32 and the back of the body female 5, by locking nut 2, nut sleeve 3 and axis connecting rod 1 are fixed again, make axis connecting rod 1 and big-canopy framework 4 realize being rigidly connected, add the rigidity of whole booth.
Multiple big-canopy framework 4 couples together by the present invention's axis connecting rod 1, and big-canopy framework 4 and axis connecting rod 1 is coupled together by axially locating locking device, improves big-canopy framework 4 rigidity and installation efficiency.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
