LOCKING DEVICE OF MANHOLE COVER AND FRAME}

The present invention relates to a locking mechanism of the support frame and the cover for preventing the noise of the support frame and the cover of the manhole and the detachment of the cover.

In general, a manhole is installed in the water, sewage, communication line, etc. buried underground, and a cover for opening and closing the manhole is provided at the top of the manhole through a support frame. When a shock is applied by various kinds of vehicles passing by, not only severe noise is generated due to friction with the support frame, but also in severe cases, the cover is separated from the support frame, causing a safety accident.

Therefore, all existing manhole support frames and covers prevent the occurrence of noise and cover by locking using various technical means, and it is considered that it is most preferable to use spring elasticity as a technical means satisfying both functions at the same time. have.

Accordingly, the present applicant has also provided a registration utility model No. 285786 for the coupling structure of the manhole cover and the supporting frame using a leaf spring.

However, registered utility model No. 285786 is installed by connecting a plate spring having a V-shaped locking portion on the outside of the manhole cover with bolts so that the locking portion is semi-forcibly caught on the bottom of the locking jaw of the support frame when combined with the supporting frame. Its elasticity acts downward of the manhole cover to satisfy noise generation and cover separation prevention functions.

Therefore, the structure of the manhole support frame and the cover of this structure allows the plate spring to be installed by connecting several bolts to the manhole cover to achieve the desired purpose, resulting in an increase in the purchase cost of parts and a lot of time when assembling. Since the connection part of the leaf spring and the V-shaped groove having the bolt and the locking part are exposed in appearance, the appearance is not beautiful, and when various foreign substances are introduced into the exposed V-locking part, it becomes difficult to grind the V-shaped locking part. Many problems, such as being very difficult and difficult to catch the locking portion for opening and closing the cover during use are pointed out.

The present invention satisfies the original function to prevent noise and separation of the cover while reducing the manufacturing cost and assembly time of parts during manufacturing, and can maintain a smooth appearance and there is no fear of infiltration of foreign substances from the outside It is an object of the present invention to provide a crimson support frame and a cover locking device which can be quickly and easily unlocked by a lock for opening and closing a cover.
