Abstract

The utility model provides an anti-theft sewer cover, and the anti-theft sewer cover includes a well cover board and a mechanical lock core, the mechanical lock core is immovably arranged on the center of the well cover board, and is connected with rotary connecting rod, the two movable connecting points of the rotary connecting rod are connected with bolt connecting rod; the bolt connecting rod is arranged inside the through-hole on the U-shaped figurate bracket fixed on the well cover board. When application, the well cover board is buckled on the well loop, and special key is used to rotate the lock core, so the bolt connecting rod is brought to insert into the lock nose on the well loop, so as to play a role of anti-theft. When opening the well cover board, the key is used to rotate the lock core, then the well cover board can be completely separated from the well loop, thereby the hidden trouble that the well cover board is dropped down because vibration is overcome.

Description

A kind of antitheft plug for sink

The utility model relates to the cover plate that use in cloaca, a kind of public place, relates in particular to a kind of plug for sink that anti-theft feature is arranged.

In the prior art, the cloaca well head of public place generally covers in walling crib with the well lid plate, is not added with anti-theft device.The patent No. is that the Chinese utility model patent that Z L98233425.7, name are called " a kind of Cover for manhole " discloses a kind of antitheft Cover for manhole, and an end of well lid plate is connected with well lid by shaft coupling, and the other end of well lid plate is equipped with mechanical lock.The well lid plate closes after walling crib, uses special key rotation lock core, and dead bolt is entered in the lock nose of walling crib, plays antitheft effect.But the defective of this utility model patent is: when the sanitationman unblanked to open the well lid plate and carries out operation, because an end of well lid plate is still connected with well lid by shaft coupling, the well lid plate was easy to be pounded down because of shaking, and has potential safety hazard.

The purpose of this utility model provides a kind of antitheft plug for sink, and this plug for sink has compared with prior art overcome the well lid plate because of being shaken the potential safety hazard under pounding.

To achieve these goals, the antitheft plug for sink that the utility model provides is design like this: this antitheft plug for sink includes well lid plate, mechanical lock; It is characterized in that: the described mechanical lock of a. is fixedly installed in the center of well lid plate; Mechanical lock has been connected with the rotation connecting rod of gearing, and two active interfaces of rotation connecting rod are equal to the distance of the central point of connecting rod; Two active interfaces of b. described rotation connecting rod have been connected with the dead bolt connecting rod of dead bolt effect, and described rotation connecting rod is a loose fit with the end points that connects of dead bolt connecting rod; The described dead bolt connecting rod of c is installed in the through hole of the U-shaped setting frame that is fixed on the well lid plate, and described dead bolt connecting rod cooperates for movable with the through hole of U-shaped setting frame.

During the antitheft plug for sink that uses that the utility model provides, the well lid plate is closed after walling crib, use special key rotation lock core, the rotation connecting rod rotates thereupon, drives in the lock nose of dead bolt connecting rod insertion walling crib, has finished closed work, and has played antitheft effect.If in the time of will opening the well lid plate because of operation, use special key rotation lock core, the rotation connecting rod rotates thereupon, drives the lock nose that the dead bolt connecting rod breaks away from walling crib, can with the well lid plate fully and walling crib unload disengaging, overcome the well lid plate because of being shaken the potential safety hazard under pounding.

Fig. 1 is the schematic diagram of the antitheft plug for sink of the utility model when open mode.

Fig. 2 is the schematic diagram of the antitheft plug for sink of the utility model when closure state.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

From accompanying drawing as can be seen: this antitheft plug for sink includes well lid plate 1, mechanical lock 2.Described mechanical lock 2 is fixedly installed in the center of well lid plate 1; Mechanical lock 2 has been connected with the rotation connecting rod 3 of gearing, and two active interfaces 5 of rotation connecting rod 3 are equal to the distance of the central point of connecting rod.Two active interfaces 5 of described rotation connecting rod 3 have been connected with the dead bolt connecting rod 4 of dead bolt effect, and described rotation connecting rod 3 is loose fit with the end points 5 that connects of dead bolt connecting rod 4.Described dead bolt connecting rod 4 is installed in the through hole of the U-shaped setting frame 6 that is fixed on the well lid plate 1, and described dead bolt connecting rod 4 cooperates for movable with the through hole of U-shaped setting frame 6.

In order to cooperate the antitheft plug for sink of this utility model, must use the special key that matches with mechanical lock, in addition, walling crib must be bored the lock nostril.Mechanical lock can adopt type common in the prior art.

Under special situation,, then need not bore the lock nostril if the thickness of well lid plate is identical with the thickness of walling crib.

The utility model also can be transformed the plug for sink in existing city: as long as former plug for sink is installed additional mechanical lock, rotation connecting rod and dead bolt connecting rod; Secondly, former walling crib is added brill lock nostril, can be adapted as antitheft plug for sink.
