State concrete meaning of the term in the utility model creation.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1 to 4, a kind of self-locking nut available for inclined-plane installation, include installation drive division 1 successively, determine power
Square portion 2, with female dismounting drive division 6 and nipple heads 4；
The outer dia of the nipple heads 4 is more than the outer dia of dismounting drive division 6, and the inside bag of nipple heads 4
Transition part 41, receiving portion 42 and joint portion 43 are included, receiving portion 42 is between transition part 41 and joint portion 43, the transition
The side wall of portion 41 and joint portion 43 is interior concave spherical surface, and the side wall of described accommodation section 42 is cylindrical；
The dismounting drive division 6 is provided with tight lock part 3.The outside of the nipple heads 4 includes spherical transition portion
And circular cylinder shaped portion.The installation drive division 1 and dismounting drive division 6 are twelve-point head.
It is described to determine the cut-off neck slot that torque portion 2 is indent；The cut-off neck slot is inclined-plane close to a side wall of installation drive division 1,
Side wall close to dismounting drive division 6 is that the bottom surface between dismounting drive division 6 outer wall vertical face, two side is parallel surface,
Its inwall parallel to nut；And the inclined-plane is relative to angle of inclination≤12 ° of parallel surface；The depth of the cut-off neck slot is
0.8~3mm.The installation drive division 1 is 1 with the length ratio for dismantling drive division 6:2.The joint portion 43 of the nipple heads 4
The diameter ratio at both ends is 1:1.5.
The tight lock part 3 of the dismounting drive division 6 is so as to realizing the screw thread of Inward deflection by radial pressure.The dismounting
The wall of drive division 6 is evenly equipped with tight lock part 3 at three.
The installation drive division 1 is when install nut, nut is tightened for installation, and design uses for spanner twisting
Position, it is easy to spanner twisting.Installation drive division 1 is designed as twelve-point head, not only may be used to the strong adaptability of installation tool, during installation
Using fork spanner, monkey wrench can also be used, can also be installed using box spanner.
It is cut-off neck slot to determine torque portion 2, when being installation nut, to make nut reach defined mounting torque value when mounted
When, this, which determines torque portion 2, to be broken, and the installation drive division 1 of nut just disconnects from there, depart from nut body, so as to lead
Cause nut to continue to apply mounting torque, complete installation, and realize the purpose for determining torque installation.Closed because cut-off neck slot designs
Reason, after ensureing fracture, corresponding nut body end face is flat, and is more easily controlled and determines torque.By the depth for changing cut-off neck slot
To change the size that cut-off neck slot twists into two parts torque, so as to meet the installation of the high-torque on steel construction, on honeycomb
Small torque installation and the accurate installation in fine structure, constantly can effectively ensure the clamping force suffered by mounted configuration, and
And can protect to greatest extent mounting structure not because apply mounting torque it is unreasonable cause to fail or destroy.
Tight lock part 3 is previously applied certain power in the screw thread position of nut, the screw thread of nut is produced certain plasticity and becomes
Shape, so as to realize the purpose of nut self-locking.Its principle is exactly the receipts in seaming tool operational module 9 (as shown in Figure 13~Figure 15)
In the presence of mouth power, nut thread is deformed in advance, the central diameter of screw thread is less than the central diameter of normal screw thread, the nut and same specification
Bolt when being used cooperatively, when bolt is screwed onto the screw thread position of deformation of nut, under the support of bolt thread, nut deformation
Screw thread position resilience, while be in close contact with bolt thread, after bolt is installed in place, effect of the nut thread in distortional stress
Under be tightly engaged with bolt thread, reach the purpose of self-locking (as shown in Fig. 5~Fig. 7).
During demounting bolt, after bolt thread completely disengages out the screw thread of nut deformation position, in the presence of elastic force, spiral shell
Box thread returns to deformation state again, realizes the self-locking of nut.Nut is due to that with dismounting driving part, can realize spiral shell simultaneously
The purpose (as shown in Figure 9) that maternal is just dismantled.
Receiving portion 42 be nut with after the installation of bolt 8, for accommodating the screw-thread ending position of bolt, while can be real
The installation question (as shown in figure 16) that existing adjust installation portion position is brought due to the became uneven of thickness of interlayer.Described self-locking nut
State after Plane Installation, as shown in figure 11；State of the self-locking nut after inclined-plane installation, as shown in figure 12.
Joint portion 43 is the supporting portion of nut, is used cooperatively with convex spherical packing ring 5, can reach mounting location and adapt to by force
Purpose, not only can in the plane install, can also realize and be installed on inclined-plane, maximum installation gradient can reach 12 °, this
It is the maximum installation gradient that the current field can reach.Be used cooperatively with convex spherical packing ring, can flexibly be used in plane and
Inclined-plane, the mechanical erection of various occasions can be met.The sphere of the sphere of nut and packing ring is in close contact during installation, it is possible to achieve
Certain angle installation is presented between nut axis and the normal of mounting surface, plain nut can not then realize this purpose.
And joint portion 43 is interior concave spherical surface, convex spherical packing ring 5 is convex spherical, is easy to fix on convex spherical packing ring 5, Ke Yiwei
Realize that the installation in narrow space provides convenience, plain nut is unable to reach this installation purpose.
Dismounting drive division 6 is nut with the installation pair of bolt 8 when needing to disassemble, for spanner twisting nut.Spanner card
Firmly after the dismounting driving part of nut, unscrew nut along the direction opposite with installation tightening direction, you can reach dismounting nut
Purpose (as shown in Fig. 8~Figure 10).
A kind of attachment means for inclined-plane installation, including the self-locking nut as described above available for inclined-plane installation, with
And the convex spherical packing ring 5 being engaged with the interior concave spherical surface of the joint portion 43 of nipple heads 4.
The preferred embodiment of the utility model creation is the foregoing is only, is not created to limit the utility model
Make, within all spirit and principle created in the utility model, any modification, equivalent substitution and improvements made etc., all should include
Within the protection domain that the utility model is created.
