DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2 The figure shows an anti-falling manhole cover, including a mounting seat 1, a hinge seat 2 is fixedly installed on the outer side of the mounting seat 1, a manhole cover body 3 is movably embedded on the upper end of the mounting seat 1, a connecting block 4 is fixedly installed on the outer side of the manhole cover body 3, a connecting shaft 5 is fixedly penetrated inside the connecting block 4, and also includes a mounting groove 6 for the connecting shaft 5 to enter the interior of the hinge seat 2, and two symmetrically distributed mounting grooves 6 are opened on the inner wall of the hinge seat 2; a locking structure 7 is used to prevent the mounting seat 1 from opening, and the locking structure 7 is installed on the lower side of the mounting seat 1.

[0023] See also Figure 4 The locking structure 7 includes two connection seats 701 fixedly connected to the manhole cover body 3, and the two connection seats 701 are symmetrically distributed. A pin rod 702 is movably embedded at one end of the two connection seats 701 away from each other, and the pin rod 702 is cylindrical in shape.

[0024] See also Figure 4 The outer side of the pin rod 702 is located outside the connecting seat 701 and is movably sleeved with a plug-in socket 703. The connection between the pin rod 702 and the plug-in socket 703 is a plug-in connection, and the plug-in socket 703 is fixedly connected to the mounting seat 1. The pin rod 702 is located inside the connecting seat 701 and one end is fixedly connected with a gasket 704. A spring 705 is installed inside the connecting seat 701, and the spring 705 can drive the pin rod 702 to move.

[0025] See also Figure 4 The two ends of the spring 705 are respectively movably abutted against the connecting seat 701 and the gasket 704. The gasket 704 can prevent the pin rod 702 from detaching from the connecting seat 701. A steel cable 706 is fixedly embedded in the inner center of the gasket 704. A pull ring 707 is movably embedded between the two connecting seats 701 on the mounting seat 1. One end of the steel cable 706 away from the gasket 704 is fixedly connected to the pull ring 707. Guide rods 708 are installed on the outer side of the steel cable (706) at multiple bending places thereof. The guide rods 708 can reduce the wear of the steel cable 706.

[0026] Working principle of preventing the manhole cover from being washed away: When backflow occurs in the city manhole, the pin rod 702 is inserted into the inside of the socket 703 to lock the manhole cover body 3, which can effectively prevent the manhole cover body 3 from being washed away by water;

[0027] When a person opens the manhole cover body 3, he or she uses a hook to hook the pull ring 707 and lifts the pull ring 707. The pull ring 707 pulls the pin rod 702 into the interior of the connecting seat 701 through the steel cable 706, so that the pin rod 702 is separated from the connecting seat 701. At this time, the person continues to hook the pull ring 707 and lifts it, so that the manhole cover body 3 can be easily opened.

[0028] Embodiment 2

[0029] See also Figure 3 This embodiment further illustrates the first embodiment, and a reserved groove is provided on the manhole cover body 3 at the pull ring 707 .

[0030] In this embodiment: after hooking the pull ring 707 to close the manhole cover body 3, the personnel removes the tool from the pull ring 707. At this time, the pin rod 702 will extend from the inside of the connecting seat 701 driven by the spring 705, and insert into the inside of the plug-in seat 703 to lock the manhole cover body 3, and the pull ring 707 will move downward under the drive of the steel cable 706 and embed into the inside of the manhole cover body 3, so that the upper end surface of the pull ring 707 is flush with the upper end surface of the manhole cover body 3, thereby effectively preventing the protrusion of the pull ring 707 from affecting the driving of the car.

[0031] Embodiment 3

[0032] See also Figure 3 This embodiment further illustrates other embodiments, and the mounting groove 6 is divided into a horizontal portion and an inclined portion.

[0033] In this embodiment: when the manhole cover body 3 is damaged and needs to be replaced, the personnel first rotate the manhole cover body 3 to open it, then move the connecting shaft 5 in the horizontal part of the installation groove 6, and then move the connecting shaft 5 out of the inclined part of the installation groove 6, so that the manhole cover body 3 can be quickly disassembled and assembled, thereby facilitating the replacement of the damaged manhole cover body 3.
