Problems solved by technology

[0002] The position where the manhole cover is installed in the sewer usually has a concrete structure, and the sewer manhole cover is installed above the concrete structure. Since the manhole cover is directly covered on the concrete structure, in order to keep the manhole cover stable, the manhole cover is usually provided with a thicker structure to increase its weight. Not easy to shift, but easy to be stolen since the manhole cover is directly on the concrete

Embodiment 1

[0027]In this embodiment, in order to facilitate the installation of the cylinder, preferably, a bracket 115 with a U-shaped cross section is provided on the lower end surface of the well cover 102, so that the lower end surface is suspended relative to the well cover, so that the support 115 The end face is welded on the lower end face of the well cover 102. In order to facilitate the installation of the cylinder, a through hole is provided on the support 115, so that two through holes are arranged symmetrically, and the upper end of the cylinder 108 runs through the The through hole on the bracket 115 makes the outer diameter of the cylinder smaller than the inner diameter of the corresponding through hole, so that the cylinder can rotate relative to the support, and a boss 116 is arranged on the upper end of the cylinder 108, and the boss 116 The outer diameter is larger than the inner diameter of the through hole. Under the action of the boss, the cylinder cannot move belo...

Embodiment 2

[0031] Since the manhole cover is usually buried on the ground, under high temperature and other conditions, the pavement formed by laying asphalt is prone to deformation, so that the frame is squeezed. , in order to improve the stability of the frame and prevent the deformation of the frame under external force, affecting the opening of the well cover, preferably, a reinforcing rib 120 is provided on the outer edge of the frame 103, and the reinforcing rib connects the outer wall of the frame and the outer surface of the well cover. frame, preferably, the reinforcing rib 120 has a right-angled triangle structure, one right-angled side of the reinforcing rib 120 is fixedly connected to the outer wall of the frame 103, and the other right-angled side of the reinforcing rib 120 is fixedly connected to the On the well cover frame 101 described above. By making the reinforcing rib support the frame, the frame is supported on the inner side of the manhole cover frame through the re...

Abstract

The invention discloses a well lid anti-theft device. The well lid anti-theft device comprises a well lid outer frame and a well lid arranged at the inner side of the well lid outer frame, wherein a side frame which is in the shape of a hollow barrel is arranged on the middle part of the well lid outer frame; a ring-shaped baffle plate is arranged at the inner side of the side frame; two strip-shaped slots which are uniformly distributed are formed in the baffle plate; the end parts of the strip-shaped slots are equipped with supporting plates; fixed slots are formed in the supporting plates;cross sections of the fixed slots are in the shapes of L with opening facing leftward; the well lid is blocked to the inner side of the side frame; two cylinders which are uniformly distributed are arranged on the lower end surface of the well lid; the lower ends of the cylinders can be spliced into the corresponding strip-shaped slots; and the upper ends of the cylinders are rotatably connected onto the lower end surface of the well lid. According to the well lid anti-theft device disclosed by the invention, the well lid with a fixed rod is combined with the baffle plate with the supporting plates, so that the well lid can be blocked onto the baffle plate, and therefore, a good anti-floating function and a good anti-theft function can be achieved.

Description

technical field [0001] The invention relates to a well cover anti-theft device. Background technique [0002] The location where the manhole cover is installed in the sewer usually has a concrete structure, and the sewer manhole cover is installed above the concrete structure. Since the manhole cover is directly covered on the concrete structure, in order to keep the manhole cover stable, the manhole cover is usually provided with a thicker structure to increase its weight. Not easy to shift, but since the manhole cover is directly on the concrete, it is easy to be stolen. Contents of the invention [0003] The object of the present invention is to provide a well cover anti-theft device, which can improve the problems existing in the prior art. By combining the well cover with the fixed rod and the baffle provided with the support plate, the well cover can be clamped on the baffle, Can play a good anti-floating, anti-theft function. [0004] The present invention is real...
