Problems solved by technology
[0002] Most of the existing inspection well covers are round, and the cover is closed on the inspection well mouth, which is easy to be opened by external force and easily stolen. In addition, due to the long service time, the inspection well mouth becomes larger, and when one side of the inspection well cover is stressed, The other side will be tilted up, which poses a safety hazard, especially during heavy rains, when the road is flooded and the water flow is too fast, the inspection well cover is easily washed away, causing passers-by to fall into the inspection well

Embodiment Construction
[0013] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0014] like figure 1 As shown, a manhole cover locking device includes a manhole cover 1 and a manhole head 2. The manhole cover 1 includes a circular cover surface 3 and an annular cover neck 4 arranged under the cover surface 3. The outer wall of 4 is provided with a pair of clamping blocks 5, the wellhead 2 is a metal round sleeve, and the inner wall of the wellhead 2 is relatively provided with a Z-shaped clamping groove 6, the clamping groove 6 and the clamping block 5 Matching, the said clamping slot 6 includes two longitudinal slots 7 and a transverse slot 8 arranged between the two longitudinal slots 7, and the bottom end of the inner wall of the wellhead 2 is provided with a radially inwardly protruding rib. 9.
[0015] The diameter of the cover surface 3 is larger than the outer diameter of the cover neck 4 , and the out...

The invention discloses a locking device of an inspection well lid. The locking device of the inspection well lid comprises the inspection well lid and an inspection well mouth. The inspection well lid comprises a round lid face and an annular lid neck arranged below the lid face. A pair of clamping blocks is oppositely arranged on the outer wall of the lid neck. The inspection well mouth is a metal round sleeve. Z-shaped clamping grooves are oppositely formed in the inner wall of the inspection well mouth. The clamping grooves are in fit with the clamping blocks. A stop edge protruding inwards in the radial direction is arranged at the bottom end of the inner wall of the inspection well mouth. Compared with the prior art, the locking device of the inspection well lid has the advantages that the inspection well lid is clamped in the clamping grooves in the inspection well mouth through the pair of clamping blocks on the lid neck, and a person can take the inspection well lid out of the inspection well mouth by pulling, rotating and pulling again; by means of the locking device of the inspection well lid, the inspection well lid can be effectively prevented from tilting or being flushed away by water, potential safety hazards are avoided, and meanwhile a certain anti-theft function is achieved.
Description
technical field [0001] The invention relates to a manhole cover locking device. Background technique [0002] Most of the existing manhole covers are round, and the cover is closed on the manhole head, which is easy to be opened by external force and easily stolen, and some of the manhole heads become larger due to the long use time. When the manhole cover is subjected to force, The other side will stick up, posing a potential safety hazard, especially during heavy rains, when the water and currents on the road are too fast, and the manhole cover is easily washed away, causing passersby to fall into the manhole. SUMMARY OF THE INVENTION [0003] The above problem to be solved by the present invention is to provide a manhole cover locking device in view of the above-mentioned shortcomings of the prior art. [0004] In order to solve the above-mentioned technical problems, the technical scheme adopted in the present invention is: [0005] A manhole cover locking device inc...
