Abstract
The utility model provides a rolling needle type anti-disassembly nut, and relates to a machine fixing component. The inner wall of the nut has no screw; three oblique slots are formed on the nut, and rolling needles are arranged in the oblique slots. Rolling needle protecting covers are arranged in the nut. Compared with the existing anti-theft nut, the utility model has the advantages of multipoint locking, uniform stress, strong anti-disassembly capability and high safety and reliability. The utility model is installed in a push type, and only needs to be pushed by hands instead of a spanner, so the installation is convenient and the work efficiency is enhanced. Especially, an iron tower is installed in fields, and manpower and material resources are obviously saved.
Description
Technical field:
The utility model relates to mechanical fasteners part, particularly nut.
Background technique:
Nut is the machanical fastener of using always, in some special fields, as places such as power transmission and transformation iron tower, car plate, freeway guardrail, railway protecting wire nets, need to use anti-assembling nut, what present anti-assembling nut was relatively more commonly used is internal thread, and there is a fluting nut body inboard, places steel ball in the groove.All there is deficiency no matter also be to use on the structure, a bit anti-unloading, the anti-ability of unloading is strong inadequately, and it is convenient inadequately that screw thread screws installation, particularly open-air the installation.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of needle-type anti-loosing and anti-assembling nut is provided, and is simple in structure, and the anti-ability of unloading is strong, and it is convenient to install.
The technological scheme that the utility model is adopted for achieving the above object is: the needle-type anti-loosing and anti-assembling nut, nut inner wall does not have screw thread, has three skewed slots on the nut, places needle roller in the skewed slot, and Cover for fixing needle head is housed in the nut.
Described needle roller cross section is trapezoidal.
The utility model is compared with existing anti-theft nut, and multiple spot locking is stressed even, and the anti-ability of unloading is stronger, safe and reliable; Adopt pusher the installation during installation, only with hand just advance can, needn't use wrench, it is more convenient to install, increase work efficiency, field installation iron tower especially, it is more remarkable to use manpower and material resources sparingly.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A view.
Embodiment:
Needle-type anti-assembling nut as shown in the figure, nut 1 inwall does not have screw thread, has three skewed slots 2 on the nut, and nut adopts the moulding of carbon steel one-step casting, places needle roller 4 in the skewed slot, and it is trapezoidal draw point that needle roller adopts the cross section, and Cover for fixing needle head 3 is housed in the nut.
During installation, the pusher nut of installing, Cover for fixing needle head is released by bolt in the nut, when nut (when the promptly tightening) needle roller that turns clockwise is pressed against the big end of skewed slot circular arc, do not influence advancing of nut, till screwing, during the inhour rotation (when dismantling), needle roller is by the drive of self gravitation and bolt external diameter, and the big end of needle roller sticks in the bolt thread, along with the rotation needle roller slides along inclined-plane down fold small angle direction, contact tighter with bolt, the compressing nut produces radial force, makes nut can not continue rotation, reaches the anti-purpose of unloading.
Claims (2)
1, needle-type anti-assembling nut is characterized in that: nut (1) inwall does not have screw thread, has three skewed slots (2) on the nut, places needle roller (4) in the skewed slot, and Cover for fixing needle head (3) is housed in the nut.
2, needle-type anti-assembling nut according to claim 1 is characterized in that: needle roller (4) cross section is trapezoidal.
