Description
Technical field
The utility model relates to a kind of safety pin, relates in particular to a kind of mechanically operated safety pin that is used for.
Background technique
It is cylindrical or conical that safety pin mostly is, and generally serves a dual purpose in mechanical transmission, connects component on the one hand; transmit rated load, on the other hand, when load surpasses maximum safety coefficient; safety pin is at first cut off, and transmission is interrupted, thus the safety of other component of protection equipment.As shown in Figure 1, it is a safety pin common in the prior art, generally is used in the wheel hub and the wheel rim connection place of coupling, sprocket wheel or gear and bears the position of heavy load.For the safety of other component of protection equipment, the diameter of safety pin calculates and does not generally get safety coefficient, just destroys but be slightly smaller than ultimate strength.
In order to connect component, transmit rated load, when the prior art safety pin is assemblied on the component, adopt transition fit more, require great effort during assembling, need safety pin be squeezed in the pin-and-hole with instruments such as hammers; If safety pin is cut off in mechanical transmission, so, it also is a thing that wastes time and energy that the safety pin that ruptures is taken out from pin-and-hole, need with screw tap tapping screw on the fracture surface of safety pin, screw with correspondence screws in screw again, by the pulling screw, the safety pin of fracture could be pulled out from pin-and-hole at last.
The model utility content
The utility model then provides a kind of new mechanically operated safety pin that is used for, and is used for solving or improving above problem.
The utility model is achieved through the following technical solutions: a kind ofly be used for mechanically operated safety pin, comprise shank, it also comprises screw rod and fastener head;
Described shank, screw rod, fastener head connect successively, and screw rod one end connects an end of shank, and the screw rod the other end connects fastener head, and the longitudinal center line of shank, screw rod, fastener head is on the same axis;
The diameter of described screw rod is greater than the diameter of shank;
The diameter of described fastener head is greater than the diameter of screw rod.
Further, described shank is cylindrical shank.
Further, described screw rod comprises outside thread.
Further, described fastener head is the hexagon fastener head.
The beneficial effects of the utility model are: the utility model is used for mechanically operated safety pin, by a end screw rod is set at shank, the other end of screw rod is provided with fastener head, thereby when making safety pin be assemblied on the component, do not need safety pin to be squeezed in the pin-and-hole with instruments such as hammers, only need by the rotation fastener head, thereby driving screw rod rotates synchronously, the outside thread of screw rod is mutually meshing with the default screw (needing the default screw of corresponding position of pin-and-hole on component) on the component, and then drives the pin-and-hole on the shank screw-in component.In the time of need from pin-and-hole, taking out shank, only need the counterrotating fastener head, drive the rotation of screw rod synchronous backward, and then can drive the pin-and-hole on the shank back-out component.The utility model can conveniently carry out the dismounting of safety pin.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further detailed.
Fig. 2 is used for mechanically operated safety pin structural representation for the utility model, and the utility model is used for mechanically operated safety pin 36 and comprises shank 365, screw rod 361 and fastener head 363; Described shank 365, screw rod 361, fastener head 363 connect successively, and screw rod 361 1 ends connect an end of shank 365, and screw rod 361 the other ends connect fastener head 363, and the longitudinal center line of shank 365, screw rod 361, fastener head 363 is on the same axis; The diameter of screw rod 361 is greater than the diameter of shank 365; The diameter of fastener head 363 is greater than the diameter of screw rod 361.
Fig. 3 is for needing to install the mechanical transmission component cross-sectional view that the utility model is used for mechanically operated safety pin, comprise axle 32, axle sleeve 31, gear 34, described axle 32 has an axial side grain, and is corresponding with it, axle sleeve 31 also has an axial side grain, and axle 32 can be socketed in the axle sleeve 31; Gear 34 is socketed in axle sleeve 31; Also be provided with pin-and-hole 33 on the axle sleeve 31, the axial side grain of the longitudinal center line of described pin-and-hole 33 and axle sleeve 31 is vertical; Corresponding position at gear 34 and pin-and-hole 33 also is provided with screw 35, and the longitudinal center line of the longitudinal center line of described screw 35 and pin-and-hole 33 is on the same axis.
Fig. 4 is used for mechanically operated safety pin and mechanical transmission component annexation schematic representation for the utility model, in conjunction with shown in Figure 2, the utility model is used for mechanically operated safety pin 36, by a end screw rod 361 is set at shank 365, the other end of screw rod 361 is provided with fastener head 363, thereby when making safety pin 36 be assemblied on the component, do not need safety pin 36 to be squeezed in the pin-and-hole 33 with instruments such as hammers, only need by rotation fastener head 363, thereby driving screw rod 361 rotates synchronously, the outside thread of screw rod 361 is mutually meshing with the screw 35 on the gear 34, and then in the pin-and-hole 33 on the drive shank 365 screw-in axle sleeves 31.When from pin-and-hole 33, taking out shank 365, only need counterrotating fastener head 363, drive the rotation of screw rod 361 synchronous backwards, and then can drive the pin-and-hole 33 that shank 365 screws out on the axle sleeve 31 as needs.
Fig. 2, Fig. 3 and shank 365 shown in Figure 4 are cylindrical, in actual applications, also can be conical, as long as guarantee that its conical stub end is connected with screw rod 361, its conical little head end enters pin-and-hole and gets final product.
The outside thread of the utility model screw rod 361 is triangle single threads, certainly, also can adopt different external thread form, with the screw internal thread of the different form of correspondence.
The utility model fastener head 363 is outer-hexagonal shape fastener heads, and hexagon fastener head in also can adopting certainly is as long as make things convenient for the dismounting of component and the operation of machinery.
Above embodiment has been described in detail the utility model, and formation is to restriction of the present utility model but these are not.Protection domain of the present utility model does not exceed with above-mentioned mode of execution, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
