The invention discloses a well lid with the anti-theft function. The well lid comprises a well base and a lid body, a through hole is formed in the middle of the well base, one side of the lid body is hinged to the well base, a shoulder supporting lid body is arranged on the inner wall of the through hole, the other side of the lid body is provided with a vertical opening through hole and a transverse locking hole penetrating the vertical opening through hole and the side face of the lid body, the lower portion of the vertical opening through hole is located on a shoulder, a pushing pin and a first pressure spring are arranged in the transverse locking hole, the first pressure spring presses the pushing pin to enable one end of the pushing pin to stretch into the vertical opening through hole, the upper portion of the vertical opening through hole is connected with a protection plug, a transverse assembling hole is formed in the position, close to the transverse locking hole, of the well base, and a locking pin and a second pressure spring are arranged in the transverse assembling hole; the second pressure spring presses the locking pin to enable one end of the locking pin to stretch out of one side of the through hole; when the lid body is closed, one end of the locking pin is clamped in the transverse locking hole, and when the lid body needs to be opened, the pushing pin can push the locking pin to be separated out of the lid body. The well lid has the anti-theft property, and the lid body can be opened and closed conveniently.
Description
technical field [0001] The invention relates to the technical field of well cover manufacture, in particular to a well cover with anti-theft function. Background technique [0002] In urban municipal facilities, various underground pipelines and pipelines have wellheads to facilitate maintenance, and these wellheads need to be provided with well covers for sealing. The well cover is usually composed of a well seat and a cover body. At present, the cover body of a well cover made of iron material is easy to be stolen. Once the cover body is stolen, the wellhead will lose its seal, which brings safety hazards to pedestrians and vehicles. Therefore people begin to set some anti-theft facilities to the manhole cover, as on June 05, 2013, an application number is 201110381083. The ring is connected, and a lock is set inside the manhole cover to lock the manhole cover and the manhole cover ring. Since the lock of this kind of anti-theft manhole cover is arranged inside the cover...
