Abstract
The invention discloses an electric structure of an electric control lock for a manhole cover. The electric structure comprises a latch sleeve and a reducing motor which are fixed on the manhole cover, wherein an eccentric rotating device is mounted on the output shaft of the reducing motor; a protruded power driving device is arranged on the edge of the eccentric rotating device; a front latch hole and a rear latch hole are correspondingly formed in the front end and the rear end of the latch sleeve; the latch sleeve is sleeved on a latch through the rear latch hole of the latch sleeve; a guiding slotted hole perpendicular to the moving direction of the latch is connected to the rear section of the latch; and the power driving device extends into the guiding slotted hole. According to the electric structure disclosed by the invention, the original mode for controlling the stretch of a control lock or a bayonet lock thereof by using electromagnetic energy is changed into a mode of changing circular motion of the reducing motor into linear motion of the manhole latch. Compared with the stretching motion, the circular motion has the effects that sand and water are easily sealed and isolated, an electronic and electromagnetic structure of the reducing motor is effectively protected and the service life of the electric control lock is prolonged.
Description
Technical field
The present invention relates to a kind of road equipment, particularly a kind of electric structure of well lid electric control lock.
Background technology
Increase along with demands such as communication, energy supply, blowdowns; The network of underground scale of modern city sharply enlarges; The manhole cover on ground is more and more thereupon, and in urban planning and construction, sewer, cable trench spread all over the streets and lanes in city as the important supporting facility in city.On sewer, cable trench, keeping at a certain distance away is provided with the vertical shaft that supplies cleaning, maintenance usefulness, and well lid is housed on vertical shaft.Because well lid is normally processed by metal material such as cast irons, the incident that therefore often has the lawless person to steal manhole cover takes place, and after manhole cover was stolen, Liu Nijing, cable trench well just can become the hidden danger of the serious threat people security of the lives and property.The pedestrian of taking place owing to lawless person's pilferage well lid behavior is at the accident of Liu Nijing, the tumble injury of the cable trench well end that appears in the newspapers repeatly.For preventing to steal the generation of manhole cover incident; Sand well lid lock is installed on the manhole cover usually; Therefore the well lid coded lock is used widely, yet common electric control lock all is directly with the stretching of electromagnetic energy control lock door bolt or its bayonet lock, and seals its expanding-contracting action howsoever and must bring sand and dust, moisture into electric controling part; Damage electrical equipment easily, the application life of electric control lock is short.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of seal sand and dust, moisture of being easy to, and has effectively protected the electric structure of the well lid electric control lock of the inner electronics of reducing motor, electromagnetic structure.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of electric structure of well lid electric control lock; Comprise the lock bolt cover and the reducing motor that are fixed on the well lid, the eccentric rotary device is installed on the output shaft of described reducing motor, said eccentric rotary device edge is provided with the actuating unit of protrusion; Said lock bolt cover front and back end correspondence is provided with forward and backward latch hole; Lock bolt cover is set with lock bolt through latch hole thereafter, and the back segment of lock bolt is connected with the guiding slotted eye perpendicular to its activity direction, and described actuating unit stretches in the guiding slotted eye;
In the present invention, said eccentric rotary device comprises the rotating disk concentric with output shaft, and the circumferential edge of rotating disk is installed with the actuating unit perpendicular to the circular motion direction;
In the present invention, described actuating unit is a drive bearing;
In the present invention, said guiding slotted eye and drive bearing matched in clearance;
In the present invention, the length of said guiding slotted eye greater than above-mentioned bearing at range of movement perpendicular to the lock bolt activity direction.
The invention has the beneficial effects as follows: the present invention is through the flexible rectilinear motion that the circular motion of reducing motor is converted into the well lid lock bolt that becomes with original electromagnetic energy control lock bolt or its bayonet lock; Circular motion is easy to seal sand and dust, moisture than stretching motion, has effectively protected inner electronics, the electromagnetic structure of reducing motor, has increased the application life of electric control lock.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
With reference to Fig. 1, a kind of electric structure of well lid electric control lock comprises the lock bolt cover 1 and reducing motor 2 that are fixed on the well lid; Eccentric rotary device 4 is installed on the output shaft of described reducing motor 2; Said eccentric rotary device 4 comprises the rotating disk 3 concentric with output shaft, and the circumferential edge of rotating disk 3 is installed with the actuating unit 5 perpendicular to the circular motion direction, and said rotating disk 3 can either play the output shaft run-in synchronism with reducing motor 2; Drive outside actuating unit 5 motions; Can also play the effect of protection reducing motor 2, effectively protect reducing motor 2 inner electronics, electromagnetic structure, prevent the erosion of sand and dust, moisture its inside.
Said lock bolt overlaps 1 front and back end correspondence and is provided with forward and backward latch hole 6,7; Lock bolt cover 1 is set with lock bolt 8 through latch hole 7 thereafter, forward and backward latch hole 6, has formed a lock bolt passage between 7, and lock bolt cover 1 has limited lock bolt 8 and can only do line activities; Lock bolt 8 leading portions can freely stretch out the preceding latch hole 6 with indentation lock bolt cover; Realize the well lid locking function, the back segment of lock bolt 8 is connected with the guiding slotted eye 9 perpendicular to its activity direction, and described actuating unit 5 stretches in the guiding slotted eye 9.
Described actuating unit 5 is a drive bearing, said guiding slotted eye 9 and drive bearing matched in clearance, the length of said guiding slotted eye 9 greater than above-mentioned bearing at range of movement perpendicular to the lock bolt activity direction; Through drive bearing and the rectilinear motion that the circular motion of reducing motor 2 output shafts 3 is converted into guiding slotted eye 9 that cooperates that leads between the slotted eye 9, guiding slotted eye 9 is connected with lock bolt 8, directly controls the motion of lock bolt 8.
When output shaft moved in a circle, above-mentioned guiding slotted eye 9 can be followed bearing movable on the direction of line activities at well lid lock bolt 8, and the maximum length of its motion equals the diameter that bearing moves in a circle.When the rotating torque of reducing motor was determined value, it is maximum that lock bolt 8 moves dynamics at former and later two points of linear reciprocation activity, moves the radius that rotating torque/bearing that dynamics equals reducing motor moves in a circle at intermediate point.
The present invention is through the flexible rectilinear motion that the circular motion of reducing motor 2 is converted into lock bolt 8 that becomes with original electromagnetic energy control lock bolt or its bayonet lock; Circular motion is easy to seal sand and dust, moisture than stretching motion, has effectively protected inner electronics, the electromagnetic structure of reducing motor, has increased the application life of electric control lock.
Certainly, the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
