DETAILED DESCRIPTION

[0024] 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 in 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.

[0025] The following is combined with Figure 1-7 To further explain this application in detail,

[0026] The present application embodiment discloses a portable valve manhole cover. Figure 1 and Figure 7 A portable valve manhole cover comprises a manhole seat 1, the manhole seat 1 comprises a manhole frame 11, a manhole slot 13 is provided in the inner cavity of the manhole frame 11, a manhole cover 12 is movably connected to the top of the manhole slot 13, a rotating column 14 is fixedly connected to one side of the manhole cover 12, the rotating column 14 is movably connected to the inner wall of the manhole slot 13, and a lifting mechanism 2 is provided on the top of the manhole cover 12;

[0027] The lifting mechanism 2 includes a recovery groove 211, which is opened inside the manhole cover 12. There are two recovery grooves 211. The inner cavity of the recovery groove 211 is movably connected with a handle 201. A positioning groove 213 is opened on one side of the bottom of the handle 201. The top of the inner wall of the positioning groove 213 is fixedly connected with a concave block 207. The bottom of the concave block 207 is movably connected with a limit strip 206. The other end of the limit strip 206 is fixedly connected with a sliding column 205.

[0028] Reference Figure 5A handle groove 210 is provided at the top of the handle 201, and a mounting groove 209 is provided in the inner cavity of the handle groove 210. The inner cavity of the handle groove 210 is movably connected with a handle 202, and a handle rotating column 203 is movably connected to one side of the handle 202. One end of the handle rotating column 203 is movable in the inner cavity of the mounting groove 209. Through the setting of the handle groove 210, the handle 202 can be pulled out from the handle 201 when in use, and can be retracted into the handle 201 when not in use, which not only provides convenience for opening the cover, but also ensures the flatness of the manhole cover 12;

[0029] Reference Figure 7 A rotating shaft 214 is movably connected to one side of the inner cavity of the limit bar 206, and the rotating shaft 214 is fixedly connected to the inner wall of the concave block 207. The setting of the rotating shaft 214 can support the position of the limit bar 206 when the handle 201 is pulled open, so that the limit bar 206 can be rotated and raised accordingly, and also plays a limiting function during use, thereby ensuring the smooth rotation of the limit bar 206;

[0030] Reference Figure 5 , both sides of the inner cavity of the recovery groove 211 are provided with a slide groove 212, the shape of the slide groove 212 is L-shaped, and the slide column 205 is movably connected to the inner cavity of the slide groove 212. Through the setting of the slide groove 212, when the handle 201 is pulled open, the slide column 205 can slide in the inner cavity of the slide groove 212, playing a guiding role, and finally stuck at the top of the L-shaped slide groove 212, playing a limiting role;

[0031] Reference Figure 2 A fixing block 15 is fixedly connected to the bottom of the manhole frame 11, and a fixing groove 3 is provided inside the fixing block 15. The fixing groove 3 is circular in shape and is distributed around the inside of the fixing block 15. By setting the fixing groove 3, when the manhole cover 12 is buried below the ground, the manhole cover 12 can be fixed by the fixing groove 3 to prevent the manhole cover 12 from being displaced after being pressed by vehicles or pedestrians.

[0032] Reference Figure 5 A buckle groove 204 is provided on one side of the inner cavity of the handle groove 210. The depth of the buckle groove 204 is lower than the height of the handle 202. The handle rotating column 203 is located on one side of the handle 202. By setting the buckle groove 204, when the handle 202 is retracted into the handle 201, the operator can grab the handle 202 more conveniently.

[0033] Reference Figure 6 A mounting column 208 is fixedly connected to one side of the inner cavity of the recovery groove 211, and the handle 201 is movably connected to the surface of the mounting column 208. The mounting column 208 can support the handle 201, so that the handle 201 can rotate inside the recovery groove 211.

[0034] Working principle: When the manhole cover 12 needs to be opened, the handle 202 is first grasped through the inner wall of the buckle groove 204, and the handle 202 drives the handle rotating column 203 to rotate inside the mounting groove 209, and then the handle 202 is rotated from a horizontal state to a vertical state, and the handle 202 is continuously lifted, and the handle 201 is lifted up through the handle 202, and the handle 201 is rotated around the mounting column 208, and at the same time, the handle 201 drives the concave block 207 to lift up, and the concave block 207 drives the rotating shaft 214, and the rotating shaft 214 drives the limit bar 206 to rotate around the rotating shaft 214, so that the limit bar 206 drives the slide column 205 to slide inside the slide groove 212. When the slide column 205 slides to the L-shaped top of the slide groove 212, the manhole cover 12 begins to be subjected to force to rotate around the rotating column 14 until it is in an open state. When the manhole cover 12 is closed and the handle 201 needs to be recovered, the handle 201 is pressed, and the slide column 205 will slide to the bottom along the slide groove 212. The slide column 205 will drive the limit bar 206 to return to the horizontal position, and then drive the handle 201 back to the inside of the recovery groove 211, pushing the handle 202, so that the handle 202 returns from the vertical to the horizontal state along the handle rotating column 203, and is recovered to the inside of the handle groove 210.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
