Abstract
Description
Technical Field
[0001] The utility model relates to the field of manhole covers, in particular to a manhole cover which is easy to open. Background Art
[0002] Manhole covers are used to cover deep wells in roads to prevent people and objects from falling. Manhole covers used on the market are generally large in size and heavy in weight. Generally, at least two people are required to work together to open and move the manhole cover to its place, which is very inconvenient to open and carry.
[0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. Utility Model Content
[0004] The utility model aims to provide a manhole cover which is easy to open.
[0005] In order to achieve the above object, the utility model adopts the following technical solution:
[0006] A manhole cover that is easy to open includes a base and a cover body, wherein the base is provided with a first connecting groove, wherein the first connecting groove is provided with two first clamping blocks that are oppositely arranged, and the cover body is provided with a second clamping block at a position corresponding to the first connecting groove, and second connecting grooves are respectively provided on both sides of the second clamping block, and the two first clamping blocks are respectively connected to the second connecting grooves in a one-to-one correspondence.
[0007] Preferably, the second connecting groove includes a first groove with a circular longitudinal section and a second groove with a rectangular longitudinal section, and the first groove is connected to the second groove.
[0008] Preferably, the first clamping block is gradually inclined from an end close to the bottom of the first connecting groove to an end away from the bottom of the first connecting groove toward a position away from the center of the base.
[0009] Preferably, an angle between a side wall of the first connecting groove corresponding to the side wall close to the outer periphery of the base and a groove bottom of the first connecting groove is greater than 90°.
[0010] Preferably, a rubber ring is further included, a third groove is formed on the side wall of the cover body, and the rubber ring is fixed in the third groove by vulcanization.
[0011] Preferably, at least one opening position is provided on the upper end surface of the cover body.
[0012] By adopting the above-mentioned design scheme, the beneficial effect of the utility model is as follows: by setting a first card block on the base and setting a second connecting groove for connecting to the first card block on the cover body, the cover body can be connected to the base through the second card block. When opening, only one person needs to pull up the cover body to open the cover body, which is more convenient for opening the manhole cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] like Figure 1-Figure 3 As shown, a manhole cover that is easy to open includes a base 10 and a cover body 20. A first connecting groove 11 is opened on the base 10. Two first clamping blocks 12 are arranged opposite to each other in the first connecting groove 11. In this embodiment, the first clamping block 12 is gradually inclined toward a position away from the center of the base 10 from one end close to the bottom of the first connecting groove 11 to the end away from the bottom of the first connecting groove 11. The angle between the side wall of the first connecting groove 11 corresponding to the side wall close to the outer periphery of the base 10 and the bottom of the first connecting groove 11 is greater than 90°, that is, the inclination direction of the side wall is consistent with the inclination direction of the first clamping block 12.
[0020] A second clamping block 21 is provided at a position of the cover body 20 corresponding to the first connecting groove 11, and second connecting grooves are respectively provided on both sides of the second clamping block 21. The two first clamping blocks 21 are respectively connected to the second connecting grooves in a one-to-one manner. In this embodiment, the second connecting groove includes a first groove 221 with a circular longitudinal section and a second groove 222 with a rectangular longitudinal section. The length of the first clamping block 12 is smaller than the inner diameter of the first groove 221. The first groove 221 is connected to the second groove 222. At least one opening position 23 is provided on the upper end surface of the cover body 20.
[0021] When the manhole cover is closed, the first clamping block 12 is connected to the first groove 221 , and when the manhole cover is opened, the first clamping block 12 is connected to the second groove 222 .
[0022] When it is necessary to open the manhole cover, the operator can insert his finger into the opening position 23, move the cover body 20 gradually away from the base 10, and the first clamping block 21 rotates in the first groove 221 until the first clamping block 12 falls into the second groove 221. At this time, the second clamping block 21 just abuts against the inclined side wall of the first connecting groove 11. There is no need to move the cover body 20 away from the base 10, and one operator can perform the operation, which improves work efficiency and avoids problems such as the loss of the manhole cover.
[0023] As a preferred embodiment of the present invention, a rubber ring is provided, and a third groove 24 is formed on the side wall of the cover body 20, and the rubber ring is fixed in the third groove by vulcanization. The rubber ring is fixed by vulcanization to prevent it from falling off, and the rubber ring is fixed in the third groove 34 to prevent it from being exposed to sunlight or being crushed by a car, thereby extending the service life of the rubber ring.
[0024] In summary, the manhole cover is easy to open and can be connected to the base 10 after opening, which effectively improves work efficiency.
[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
