Spring machinery hook
Technical field
The utility model belongs to parking equipment technical field, particularly relates to a kind of spring machinery hook.
Background technology
At present; the effective method that solves present parking difficulty is exactly multi-storied garage; and now; multi-storied garage has been come into us at one's side; but since multi-storied garage cause uncouple, fall car, pound the car event and show again and again with us, wherein be because its machinery hook fails to play a protective role greatly.Existing anti-fall hook is mainly the electromagnet hook, because its aging circuit or electromagnet fault cause it to fail to bring into play the protective effect that sweep is downloaded.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, a kind of simple in structure, easy for installation, high-efficient energy-saving environment friendly is provided, is not subjected to the spring machinery hook of such environmental effects.
The purpose of this utility model is achieved through the following technical solutions: a kind of spring machinery hook, comprise hook base, hook base is connected with rotatable extension arm by hanging arm axle, the top that hangs arm is connected with an end of extension spring by screw, the other end of extension spring is connected on the hook base by screw, the bottom that hangs arm is connected with guide runner by the guide runner bearing pin, hang the nearly crotch of arm rest place and be provided with first screw, the oblique upper that guide runner is positioned at the guide runner bearing pin is provided with second screw, is wound with torsion spring jointly on guide runner bearing pin, first screw and second screw.
Further improvement of the utility model is: the top of hook base is other to be equipped with the 3rd screw with barrier effect with hanging on the arm.
Further improvement of the utility model is: hang the arm bottom and be provided with the 4th screw, be with rubber buffer on the 4th screw.
The utility model compared with prior art has the following advantages: the utility model is simple in structure, and cost is lower, is convenient to maintenance management, easy for installation, high-efficient energy-saving environment friendly is not subjected to such environmental effects, its structure is utilized retractility and the mnemonic of spring, reaches the automatically reset form of structure of hook.The utility model has solved that the installation of the instability mode of electromagnet hook and other mechanical types hook is loaded down with trivial details, complex structure, problem that uncertain factor is many.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for hanging the structural representation of arm;
Fig. 3 is the structural representation of guide runner;
Number in the figure: 1-hook base, 2-hang arm axle, 3-hangs arm, 4-extension spring, 5-guide runner bearing pin, 6-guide runner, 7-first screw, 8-second screw, 9-torsion spring, 10-the 3rd screw, 11-the 4th screw, 12-rubber buffer.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not constitute the restriction to the utility model protection domain.
Show the specific embodiment of a kind of spring machinery of the utility model hook as Fig. 1 to Fig. 3, comprise hook base 1, hook base 1 is connected with rotatable extension arm 3 by hanging arm axle 2, the top that hangs arm 3 is connected with an end of extension spring 4 by screw, the other end of extension spring 4 is connected on the hook base 1 by screw, the bottom that hangs arm 3 is connected with guide runner 6 by guide runner bearing pin 5, hang arm 3 and be provided with first screw 7 near the crotch place, the oblique upper that guide runner 6 is positioned at guide runner bearing pin 5 is provided with second screw 8, guide runner bearing pin 5, be wound with torsion spring 9 jointly on first screw 7 and second screw 8.The top of hook base 1 is other to be equipped with the 3rd screw 10 with barrier effect with hanging on the arm 3.Extension arm 3 bottoms are provided with on the 4th screw 11, the four screws 11 and are with rubber buffer 12.
The bicycle parking process: sweep rises, hook ring on the sweep is run into hypotenuse place, extension arm bottom earlier, hang arm and constantly become big at the sweep uphill process in the angle that tilts, when the hook ring of sweep is run into guide runner, torsion spring on the guide runner deforms, and the hook central shoring by on the sweep of guide runner is opened, when the hook ring has climbed away hypotenuse place, extension arm bottom, hang arm and reset under the pulling force effect of extension spring, the bicycle parking process finishes.
The process of picking up the car: sweep rises, and guide runner opens under the pressure effect of the hook ring of sweep fully, and when the hook ring of sweep struts guide runner fully, guide runner resets under the torsion spring effect; Sweep begins to descend, and the hook ring of sweep is down moving along hypotenuse on the guide runner, hangs arm simultaneously and constantly increases the angle of inclination at pressure under effect; When the hook of sweep encircles complete guide runner, to hang arm and under the effect of extension spring, reset, this moment, the hook ring of sweep was against the hypotenuse place that hangs arm; Sweep continues down motion, breaks away from the extension arm fully until the hook ring of sweep, hangs arm and resets under the pulling force effect of extension spring.Sweep is descending, until ground, and the end of picking up the car.
The utility model is simple in structure, and cost is lower, is convenient to maintenance management, and is easy for installation, and high-efficient energy-saving environment friendly is not subjected to such environmental effects, and its structure is utilized retractility and the mnemonic of spring, reaches the automatically reset form of structure of hook.The utility model has solved that the installation of the instability mode of electromagnet hook and other mechanical types hook is loaded down with trivial details, complex structure, problem that uncertain factor is many.
