Abstract
The utility model provides an ideal prizing-proof theft-proof manhole shaft cover. The utility model is characterized in that a fixed sleeve and a reinforcing rib are arranged on a cover plate, and when the fixed sleeve and the reinforcing rib are assembled, the top of a pin shaft is thickened by beating. Because the fixed sleeve and the reinforcing rib are additionally provided, the strength of the cover plate is enhanced, the used security is added, and the phenomena of prizing off and taking down can be stopped. The utility model has the advantages of good theftproof effect, simple structure, easy manufacture, low cost, easy popularization and use, etc.
Description
The utility model belongs to the drainage structures technical field, is a kind of pick-proof and anti-theft manhole cover.
Adopt bearing pin to connect between the cover plate of existing antitheft manhole cover, the framework, promptly bearing pin one end is contained on the framework, and the other end inserts in the hole of reserving on the cover plate fixing.Because what cover plate adopted is cast iron, bad because of intensity, usually prized bad from hole portion easily.And because bearing pin can be deviate from from the hole, as long as pry open an end, other end bearing pin can be extracted out easily, and cover plate is stolen.Therefore existing antitheft manhole cover exists the deficiency of anti-theft effect difference.
The purpose of this utility model is the manhole cover of a kind of good anti-theft effect of design.
For reaching above-mentioned purpose, the main technical schemes that the utility model is taked is improved existing antitheft manhole cover, one fixed cover is set in the hole on the cover board, and on the fixed cover outer wall, reinforcing rib is housed, fixed cover, reinforcing rib are imbedded in the cover plate and are integrated with cover plate, thereby constitute a kind of pick-proof and anti-theft manhole cover.
This pick-proof and anti-theft manhole cover of the utility model provides a kind of desirable manhole cover for the drainage structures technical field.This kind manhole cover is owing to be that fixed cover, reinforcing rib are put into sandbox in advance before casting, after the cover plate of casting, so fixed cover, reinforcing rib and cover plate are integrated; Because fixed cover, reinforcing rib are to adopt low-carbon steel material to make, and have therefore improved the intensity of cover plate, have increased the safety of cover plate, block up and have cut off the phenomenon that cover plate is pried open; Owing to adopt before the assembling the bearing pin heating, the top of the cover plate end of after the assembling bearing pin being packed into is beaten slightly, thereby once can't take apart after the assembling, is to be fixed on the cloudy well outer ring with cement by framework, so has guaranteed that cover plate can't be pried open and steal.Compared with prior art, have good anti-theft effect, simple in structure, be convenient to make, cheap, be suitable for and remarkable advantage such as promote the use of.
Reach the specific structural features that example further specifies the utility model pick-proof and anti-theft manhole cover in conjunction with the accompanying drawings.
Fig. 1 represents the assembling drawing of the utility model pick-proof and anti-theft manhole cover.
