Description
Technical field
The utility model relates to a kind of union piece, specifically a kind of Drop-proof pin.
Background technique
At present, in existing project installation, pin is as important link, in long-term using process, especially in installation process, when shock conditions is more serious, existing pin can be loosening gradually, final in pin-and-hole, pin comes off from pin-and-hole, affect project installation and connect, even cause peril, have and use shortcoming inconvenient, poor stability.
Summary of the invention
The utility model, for solving the problems of the technologies described above, provides a kind of Drop-proof pin, thereby realizes the object of avoiding pin to come off under long-term use or shock conditions.
To achieve these goals, the utility model is by the following technical solutions:
A kind of Drop-proof pin is provided, and described pin is made up of pin cap and shank, and shank bottom is provided with Baltimore groove, is connected with Drop-proof plate by Drop-proof plate axle, and described Drop-proof plate rotates with respect to Drop-proof plate axle; Drop-proof plate is provided with fixture block; Drop-proof plate is connected with peach-shaped ratchet by peach-shaped ratchet rotating shaft, and described peach-shaped ratchet rotates with respect to peach-shaped ratchet rotating shaft; On described peach-shaped ratchet rotating shaft, torsion spring is installed, described torsion spring one end is fastened on Drop-proof plate axle; Described peach-shaped ratchet has two spine ends, and a described limited axle of spine end blocks, and another spine end is blocked by fixture block.
Wherein, described spine end, the spine end being connected with fixture block is longer than the spine end being connected with position-limited shaft.
Wherein, described Drop-proof plate axle and peach-shaped ratchet rotating shaft rotate, and described position-limited shaft maintains static moving.
Wherein, described Drop-proof plate axle is fixed on Drop-proof plate in shank Baltimore groove, and Drop-proof plate axle both sides are connected with the shank of Baltimore groove both sides respectively.
Wherein, described Drop-proof plate length is not less than Baltimore groove length, and described Drop-proof plate width is not more than shank width.
The beneficial effects of the utility model: anti-shotpin is loose or dislocation in long-term use or vibrations, avoid affecting the connection reliability of project installation, by being provided with anticreep plate, can make pin for convenience detach with install, have advantages of simple in structure, reasonable in design, easy to use.
Brief description of the drawings
The throwing face structural representation that Fig. 1 provides for the utility model embodiment;
The general structure schematic diagram that Fig. 2 provides for the utility model embodiment;
In figure, 1. pin, 2. Drop-proof plate axle, 3. Drop-proof plate, 3.1. fixture block, 4. torsion spring, 5. position-limited shaft, 6. peach-shaped ratchet rotating shaft, 7. peach-shaped ratchet.
Embodiment
Below in conjunction with specific embodiment, such scheme is described further.Should understand these embodiments is for the utility model being described instead of limiting scope of the present utility model.The implementation condition adopting in embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
Please refer to Fig. 1 to Fig. 2, the general structure schematic diagram that Fig. 1 provides for the utility model embodiment; The general structure schematic diagram that Fig. 2 provides for the utility model embodiment.
In a kind of specific embodiment, a kind of Drop-proof pin is provided, described pin 1 is made up of pin cap and shank, and shank bottom is provided with Baltimore groove, is connected with Drop-proof plate 3 by Drop-proof plate axle 2, and described Drop-proof plate 3 rotates with respect to Drop-proof plate axle 2; Drop-proof plate 3 is provided with fixture block 3.1; Drop-proof plate 3 is connected with peach-shaped ratchet 7 by peach-shaped ratchet rotating shaft 6, and described peach-shaped ratchet 7 rotates with respect to peach-shaped ratchet rotating shaft 6; On described peach-shaped ratchet rotating shaft 6, torsion spring 4 is installed, described torsion spring 4 one end are fastened on Drop-proof plate axle 2; Described peach-shaped ratchet 7 has two spine ends, and the described limited axle 5 of a spine end blocks, and another spine end is blocked by fixture block 3.1.
Concrete, the spine end being connected with fixture block 3.1 is longer than the spine end being connected with position-limited shaft 5, the spine end being connected with fixture block 3.1 is used for blocking Drop-proof plate 3, avoid Drop-proof plate 3 to rotate, anti-shotpin is because of loose or dislocation, the spine end being connected with position-limited shaft 5 is used for blocking peach-shaped ratchet 7, prevents that 7 rotations of peach-shaped ratchet from making torsion spring 4 lose fixation; When use, peach-shaped ratchet 7 is stuck on fixture block 3.1 in torsion spring 4 effects, makes Drop-proof plate 3 and shank be 90 ° of settings, and in the time of vibrations, torsion spring 4 can produce counterforce counteraction and shake the power applying to Drop-proof plate 3; In the time that needs unload pin, rotate by moving Drop-proof plate 3, then pin is taken out from pin-and-hole, Drop-proof plate 3 is turned back to initial position under the effect of torsion spring 4, makes Drop-proof plate 3 and shank be 90 ° of settings; As can be seen here, can avoid pin to come off, meanwhile, facilitate installation and removal.
Further, described Drop-proof plate axle 2 and peach-shaped ratchet rotating shaft 6 rotate, and described position-limited shaft 5 maintains static moving.
Further, described Drop-proof plate axle 2 is fixed on Drop-proof plate 3 in shank Baltimore groove, and Drop-proof plate axle 2 both sides are connected with the shank of Baltimore groove both sides respectively.
Further, described Drop-proof plate 3 length are not less than Baltimore groove length, and described Drop-proof plate 3 width are not more than shank width.
Finally it should be noted that the only restriction for the technical solution of the utility model is described but not to the utility model protection domain of above embodiment.Although the utility model is explained in detail with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that and can modify or be equal to replacement the technical solution of the utility model, and do not depart from essence and the scope of technical solutions of the utility model.
