Abstract
The invention discloses an automatic locking safety pin, and the safety pin comprises a safety pin main body. The upper end of a cylinder of the safety pin main body is used for cooperating with a pin hole of mobile equipment. The lower end face of a convex cylinder of the safety pin main body and an inner end of a circular hole of fixed equipment abut against springs. An end, passing out from the circular hole of the fixed equipment, of a cut-surface cylinder of the safety pin main body is fixedly provided with a handle. The main body of the safety pin main body is a multi-layer step pin, and is sequentially provided with the cylinder, the convex cylinder, a fine cylinder, a thin neck and the cut-surface cylinder from the top to the bottom. The safety pin does not need assembly welding, is simple in process, and is convenient and quick in replacement. Moreover, the safety pin does not need to be inserted into a pin seat when the safety pin is not in use, thereby effectively reducing production accidents, and improving the production.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate to a kind of auto lock safety pin.
Background technique
Locking safety pin is the widely used a kind of structure of mechanical field, and its accurate, quick position can ensure the smooth of next procedure.Traditional safety pin is that bearing pin welds chainlet, pin-and-hole is inserted during use, the used time does not extract and inserts on special key seat from pin-and-hole, the location of this kind of safety pin, to release all by manual operation, waste time and energy, and not easily change, if when not using and forget insertion key seat, also easily cause accident to occur.
Summary of the invention
The object of this invention is to provide a kind of auto lock safety pin, solve the manual operation existed in prior art, waste time and energy, and not easily change, if when not using and forget insertion key seat, also easily cause the problem that accident occurs.
The technical solution adopted in the present invention is, a kind of auto lock safety pin, comprise safety pin main body, the cylindrical body upper tip of safety pin main body is used for coordinating with the pin-and-hole of mobile device, have spring in the dome cylinder lower end surface of safety pin main body and the inner apical grafting of fixed equipment circular hole, the termination that the bevel cylindrical body of safety pin main body passes outside fixed equipment circular hole is installed with handle.
Auto lock safety pin of the present invention, is further characterized in that:
The main body of safety pin main body is multilayer steps pin, is followed successively by cylindrical body, dome cylinder, thin cylindrical body, thin neck, bevel cylindrical body from top to bottom.
The invention has the beneficial effects as follows, novel structure, safe and convenient to use, manufacture succinct, operation is few, is easy to manufacture, easily changes, not easily have an accident, improve manufacturing efficiency.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The description of following text is described at vertical position for pin, and the position in actual using process by that analogy.
With reference to Fig. 1, Fig. 2, the structure of safety pin main body 2 of the present invention is, the main body of safety pin main body 2 is multilayer steps pin, be followed successively by cylindrical body, dome cylinder, thin cylindrical body, thin neck, bevel cylindrical body from top to bottom, wherein the lower end surface (A face) of dome cylinder is spring fitting surface, the upper-end surface (C face) of dome cylinder is locked position locating face, and the cylindrical upper-end surface of bevel (B face) is unlocked position locating face.
With reference to Fig. 3, the overall structure of auto lock safety pin of the present invention is, comprise safety pin main body 2, the cylindrical body upper tip of safety pin main body 2 is used for coordinating with the pin-and-hole of mobile device 1, have spring 3 in the dome cylinder lower end surface of safety pin main body 2 and the inner apical grafting of fixed equipment 4 circular hole, the termination that the bevel cylindrical body of safety pin main body 2 passes outside fixed equipment 4 circular hole is installed with handle 5.
A-A view in Fig. 4 and Fig. 3, be fixed equipment 4 and safety pin main body 2 liang of planes coordinate schematic cross-section.
With reference to Fig. 5, when needing positioning and locking, after mobile device 1 arrives locked position, release handle 5 relies on the elastic force of spring 3 by the pin-and-hole of cylindrical for safety pin main body 2 insertion mobile device 1, upper-end surface (C face) and mobile device 1 close contact of dome cylinder, the pin-and-hole of safety pin main body 2 cylindrical body and mobile device 1 is reliably socketed, and can realize the locking and positioning function of locating stud 2.
With reference to Fig. 6, when needing to remove positioning and locking, lower handle 5 Compress Spring 3 is until the thin neck of safety pin main body 2 arrives fixed equipment 4 circular hole position, by safety pin main body 2 half-twist, see Fig. 7, the cylindrical upper-end surface of safety pin main body 2 bevel (B face) and fixed equipment 4 outer surface (bottom surface) compress locates, safety pin main body 2 can not be bounced back, due to the elastic force that spring 3 produces, play position-limiting action, safety pin main body 2 can be made to be in releasing locked position.
Contrast existing safety pin with chainlet and special key seat, chainlet generally carries out erection welding, operation more complicated.And auto lock safety pin of the present invention does not need assembling weldering, operation is simple, changes convenient and swift; And the used time does not need to insert key seat this safety pin, effectively reduces the generation of production accident, improves production.
