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.

[0034] refer to Figures 1 to 8 ,like Figure 1 , Figure 2 and Figure 3 The integrated manhole cover lock shown in the figure comprises a manhole cover 10, two flip plugging covers 20, two I-shaped parts 30, two pairs of latches 40 and wing pieces, the manhole cover 10 is installed on the base 50, the base 50 is installed on the road surface, the manhole cover 10 is provided with two lock grooves 11, the two lock grooves 11 are respectively located at the front and rear ends of the manhole cover 10, the lock grooves 11 are sleeved in the grooves (not shown in the figure) of the base 50, the flip plugging covers 20 are installed in the corresponding lock grooves 11, the flip plugging covers 20 The I-shaped member 30 is rotatably connected to the locking slot 11, and is slidably installed in the corresponding locking slot 11. A pair of latches 40 are installed on the manhole cover 10 and in two pin holes 14 located at the left and right ends of the locking slot 11 respectively. The wing includes a manhole cover wing 15 and a base wing 51. The manhole cover wing 15 is installed in the locking slot 11 at one end away from the pin hole 14, and the base wing 51 is installed in the groove on the base 50. The manhole cover wing 15 and the base wing 51 correspond to each other up and down.

[0035] Before leaving the factory, the flip plugging cover 20, the I-shaped part 30 and the latch 40 have been installed on the manhole cover 10. The installation process is to move the sliding rod 312 downward along the short groove 121 to place the I-shaped part 30 into the lock groove 11, and then place the rotating rod 231 of the flip plugging cover 20 into the flip groove 13 in the same way, and make the flip plugging cover 20 in a flipped state, and then nail the latch 40 into the pin hole 14 by external force. This reduces the steps for workers to install the manhole cover 10, and the I-shaped part 30 and the flip plugging cover 20 are integrated and installed on the cover before leaving the factory. If the construction workers do not follow the operation, the manhole cover 10 cannot be covered, which prevents the workers from not installing some parts for convenience, and can also prevent the loss of locks, making it more convenient to use.

[0036] like Figure 4 and Figure 6 The left and right sides of the lock slot 11 are both provided with slide slots 12, and the slide rod 231 of the I-shaped member 30 slides in the slide slot 12.

The short groove 121 is arranged in the vertical direction, and the long groove 122 is connected to the bottom of the short groove 121 and extends in the horizontal direction away from the pin hole 14 .

[0038] Figure 5The state diagram of the manhole cover 10 when it is placed on the base 50, at this time, the flip plug 20 is in a flip state, and the I-shaped member 30 has not yet been locked with the wing. Figure 6 It is a state diagram during the installation process, at which time the I-shaped member 30 has been interlocked with the wing.

[0039] like Figure 7 The flip plugging cover 20 includes a flat cover portion 21, a blocking block 22 and a connecting portion 23. The blocking block 22 is located below the flat cover portion 21. The connecting portion 23 is connected to one end of the flat cover portion 21 away from the I-shaped member 30. The rotating rod 231 is located in the connecting portion 23. The left and right ends of the rotating rod 231 are located in the flip groove 13. The rotating rod 231 rotates in the flip groove 13. The blocking block 22 is an arc-shaped solid structure, which can increase the weight of the flip plugging cover 20, prevent the manhole cover 10 from flipping up due to the passing of vehicles, and is safer to use.

[0040] like Figure 8 The I-shaped member 30 includes a main body member 31, a vertical member 32 and a bottom member 33, wherein the vertical member 32 is respectively connected to the lower end of the main body member 31 and the upper end of the bottom member 33, and the sliding rod 312 is connected to one end of the main body member 31 close to the flip cover 20.

[0041] like Figure 8 The I-shaped member 30 is in the shape of an I-shaped Chinese character, and the main body member 31 and the bottom member 33 form a U-shaped cavity 34 at the left and right ends of the vertical member 32 .

[0042] Preferably, the manhole cover wing 15 and the base wing 51 are both U-shaped structures. When the installation is completed, the manhole cover wing 15 and the base wing 51 are both inserted into the U-shaped cavity 34, and the upper and lower halves of the vertical member 32 are respectively located in the manhole cover wing 15 and the base wing 51, so that the wing is stuck in the I-shaped member 30, and the manhole cover 10 and the base 50 can be installed together, which is not only convenient to install but also has good anti-theft performance.

[0043] like Figure 3 The manhole cover 10 is also provided with a step groove 111, which is located above the lock groove 11, and the left and right width of the step groove 111 is greater than the left and right width of the lock groove 11. The flat cover part 21 is located in the step groove 111. Under the joint action of the flat cover part 21 and the I-shaped part 30, the manhole cover 10 is completely blocked, which can prevent dust and foreign matter from falling into the shaft, making cleaning more convenient.

[0044] Preferably, a first prying opening 311 is provided on a side of the main body 31 away from the flip blocking cover 20, and a second prying opening 211 is provided on an end of the flat cover portion 21 close to the main body 31. The first prying opening 311 and the second prying opening 211 are both used to facilitate force when installing and removing the manhole cover 10.

The latch 40 is used to block the short slot 121 to prevent the flip plug 20 and the I-shaped part 30 from being taken out manually. The latch 40 cannot be taken out under normal circumstances and needs to be operated with professional tools. This not only prevents the I-shaped part 30 and the flip plug 20 from falling out, but also reduces the chances of the manhole cover 10 being stolen, thereby further improving the anti-theft performance.

[0046] During installation, the manhole cover 10 is placed on the base 50, wherein the locking groove 11 is sleeved in the groove of the base 50, and then the I-shaped piece 30 is slid in the direction away from the flip plugging cover 20 so that the I-shaped piece 30 and the wing are locked with each other, and then the flip plugging cover 20 is flipped over and placed into the locking groove 11. When the manhole cover 10 needs to be opened, the flip plugging cover 20 is lifted up with the help of a tool to put it in a flipped state, and then the I-shaped piece 30 is slid in the direction close to the flip plugging cover 20 so that the I-shaped piece 30 and the wing are separated.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
