Problems solved by technology

[0003] At present, the manhole covers used in municipal engineering are often circular iron covers, and the manhole covers are generally higher than the road surface. When the circular iron covers are crushed by cars for a long time, the circular iron covers will vibrate due to the unevenness of the well wall bosses. , and the vibration sound is loud, so it will cause damage to the car and the road surface, and cause sound pollution
In addition, the design and structure of the manhole cover is simple, easy to be lifted, resulting in loss

Embodiment approach

[0043]The specific implementation method is: at first the shaft wall 13 is processed into the shaft wall 13 structure with the boss in the present invention, the balance adjustment mechanism 36 is installed on the boss of the shaft wall 13, and now the support column 28 is in the fourth spring 32 and the balance The adjustment mechanism 36 is in a state of free balance under the action of gravity, the rack 20 is in a state of free balance under the action of the second spring 17, and the top of the rack 20 protrudes from the lower manhole cover 15, and the block 26 is in contact with the support column 28 under the action of the adjustment block 21. Keep a certain gap; then install the adjustment snap mechanism 35 on the balance adjustment mechanism 36, at this time, the lower end of the adjustment shell 1 in the adjustment snap mechanism 35 faces the rack 20 to generate pressure, and the rack 20 is pressed into the lower well cover In the trigger chamber 34 in 15, the downward...

Abstract

The invention belongs to the technical field of well lids for municipal engineering and particularly relates to an anti-theft mute well lid used for municipal engineering. The anti-theft mute well lid comprises a well wall, an adjusting and clamping mechanism and a balance adjustment mechanism, wherein the balance adjustment mechanism is mounted on a boss of an inner circle surface of the well wall, and the adjusting and clamping mechanism is mounted on the upper side of the balance adjustment mechanism; the anti-theft mute well lid has functions of theft prevention, well lid height adjustment and well lid balance adjustment. The anti-theft mute well lid has the benefits that clamping bars extending out of adjusting grooves in an adjusting casing can be inserted into the adjusting grooves in the well wall, have the functions of limiting vertical motion and rotation motion of the adjusting casing and a top lid and prevent the well lid from being lifted up easily. The purpose of adjusting telescoping of a clamping block by rotating an adjusting shaft with an auxiliary tool inserted into a lock hole in the adjusting shaft is achieved.

Description

[0001] Technical field [0002] The invention belongs to the technical field of municipal engineering manhole covers, in particular to a silent anti-theft manhole cover used in municipal engineering. Background technique [0003] At present, the manhole covers used in municipal engineering are often circular iron covers, and the manhole covers are generally higher than the road surface. When the circular iron covers are crushed by cars for a long time, the circular iron covers will vibrate due to the unevenness of the well wall bosses. , and the vibration sound is loud, so it will cause damage to the car and the road surface, and cause sound pollution. In addition, the design and structure of the manhole cover is simple, and it is easy to be lifted and lost. [0004] The present invention designs a kind of silent anti-theft manhole cover used in municipal engineering to solve the above problems. Contents of the invention [0005] In order to solve the above-mentioned defec...
