Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] Referring to the accompanying drawings, the present invention is a device for preventing the loss of the well cover, comprising a well cover 1 and a connecting chain 2, the well cover 1 is provided with a circular through hole 3, one end of the connecting chain 2 is connected to the well wall in the well, and the other One end passes through the through hole 3 and is connected with a gear lever 4 longer than the diameter of the through hole 3 .

[0013] Well cover 1 is connected by connecting chain 2 and gear bar 4, even if opening well cover 1, because connecting chain 2 one ends are connected on the well wall in the well, well cover 1 can move within the length scope of connecting chain 2, can not lose.

Abstract

The invention provides a device for preventing well lid from missing. The device comprises a well lid and a connecting chain; a circular through hole is formed in the well lid; one end of the connecting chain is connected to the internal wall of the well, while the other end of the connecting chain goes through the through hole, and the connecting chain is connected with a stop rod which is longer than the diameter of the through hole. The device is capable of preventing the well lid from missing, and has the characteristics of safety and reliability, ingenious design, and practicability.

Description

technical field [0001] The invention relates to the technical field of urban infrastructure construction, in particular to a device for preventing loss of manhole covers. Background technique [0002] Manhole covers on the road are lost or the well water is upwelling, causing the manhole covers to be washed away frequently. Pedestrians and vehicles on the road are prone to accidents when the road conditions are unknown. In order to prevent the manhole cover from being lost, this device is designed. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a device for preventing the loss of the manhole cover, which can prevent the loss of the manhole cover, and has the characteristics of safety, reliability, ingenious design, and practicality. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] The device for pr...
