Description

Well cover fixed anti-theft device

The utility model relates to fixedly anti-theft device of a kind of well lid, is applicable to the fixing antitheft of well lids such as cities and towns tap water, sewage, rainwater and coal gas.

At present, various well lids all are freely to cover on walling crib, because external force effects such as vehicle are shifted, damage and bring traffic accident easily, also steal easily and lose.

The purpose of this utility model is to overcome the deficiency of prior art, and fixedly anti-theft device of a kind of well lid is provided, and can well lid be locked on the walling crib admittedly with key, can not be shifted and steals mistake.

The purpose of this utility model is achieved in that it comprises walling crib, well lid, and fixedly jam plate and fixed axis are installed below well lid, is set with a pair of outside plate on the fixed axis, and a pair of inner panel and movable jam plate are processed with keyhole on the well lid, and key inserts in this hole.

Well lid is placed on the walling crib, fixedly jam plate contacts with walling crib, key inserts from keyhole, and be rotated counterclockwise 90 °, the outer garden of key is towards two inner panels of preceding promotion and stir the movable jam plate angle that turns clockwise, make its end near walling crib, and by projection on it and the locking of the groove on the inner panel, pulling up the key well lid can be locked on walling crib.If key is inserted in the keyhole, turn clockwise 90 °, two surface grooves of key bump inner panel, and outer garden face is dialled movable jam plate, and it is rotated counterclockwise, and sets back, and well lid is opened, and can take off from walling crib.

The utility model compared with prior art has following advantage: simple in structure, easy to use, safe and reliable, and avoided well lid to damage because of external force effect displacement, or the traffic accident that brings because of the well head exposure, can prevent effectively that also well lid is stolen, lose.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of key.

Below in conjunction with drawings and Examples in detail the utility model is described in detail:

Fixed axis (3) is installed in below the well lid (1), its stage casing is the garden cylindricality, two ends are processed with flat (4), be set with a pair of outside plate (5) on the fixed axis (3), a pair of inner panel (12) and movable jam plate (14), order is followed successively by outside plate (5), inner panel (12), movable jam plate (14), inner panel (12), outside plate (5), and fixing by pressing plate (11) and screw (10).Have elongated slot (8) on outside plate (5) and the inner panel (12), match with flat (4) at fixed axis (3) two ends, a damping rubber block (9) respectively is equipped with in inner panel (12) position of going up keyhole (6) one sides at fixed axis (3), and it just in time is in the elongated slot (8) of inner panel (12).Respectively be processed with groove (2) on the opposite face of two inner panels (12) one ends, movable jam plate (14) go up and inner panel (12) on the upper and lower sides of groove (2) corresponding position one projection (13) is respectively arranged.

Well lid (1) is covered on walling crib (5), and the fixedly jam plate (7) that is fixed on the well lid (1) contacts with walling crib (15).Key (16) inserts keyhole (6), key (16) is the garden cylindricality, have elongated slot (17) on it, one side of elongated slot (17) is processed with two horizontal surface grooves (18) and (19), the end of movable jam plate (14) and two inner panels (12) is arranged in the elongated slot (17) on the key (16), be rotated counterclockwise (16) 90 ° of keys, its outer garden is towards preceding promotion inner panel (12), and stir movable jam plate (14), inner panel (12) compressing rubber buffer stopper (9), simultaneously, movable jam plate (14) turns clockwise, make its end contact walling crib (15), at this moment, two projections (13) place groove (2) locking about it.Pull up key (16), well lid (1) is just locked on walling crib (15).In the time of need taking off well lid (1), to turn clockwise 90 ° in key (16) the insertion keyhole (6), inner panel (12) is touched in two surface grooves (18) of key, (19), outer garden face is dialled movable jam plate (14), and movable jam plate (14) is rotated counterclockwise, and leaves walling crib (15), projection (13) is deviate from from groove (12), damping rubber block (9) discharges, and inner panel (12) resets, and well lid (1) can be opened.
