When the well lid is assembled, the well lid 1 is covered above the well lid seat 2, and the first through groove 11 and the second through groove 21 are aligned; then, the connecting piece 3 is vertically clamped into the first channel 13 and the second channel 23, and then the connecting piece 3 is transversely pushed, the upper pressing part 31 of the connecting piece 3 is clamped on the top surface of the first wing 12, and the lower pressing part 32 is clamped on the bottom surface of the second wing 22; namely, the connecting piece 3 can fasten and lock the first wing piece 12 and the second wing piece 22 together, so as to lock the well lid 1 and the well lid seat 2 together; during disassembly, the connecting piece 3 can be pushed transversely to the first channel 13 and the second channel 23, the upper pressing part 31 of the connecting piece 3 is not clamped on the top surface of the first wing 12, and the lower pressing part 32 is not clamped on the bottom surface of the second wing 22; namely, the first wing piece 12 and the second wing piece 22 are separated from the connecting piece 3 for locking, so that the well cover 1 and the well cover seat 2 can be disassembled; the first wing piece 12 and the second wing piece 12 are locked through the connecting piece 3, so that the quick assembly and disassembly between the well lid 1 and the well lid seat 2 are realized; the well lid 1 and the well lid seat 2 of the invention only need to be formed with one wing piece when in production respectively, compared with the existing well lid and the existing well lid seat which need to be formed with two wing pieces when in production respectively, the production process of the invention is simpler and more convenient to produce; the stressed contact area between each wing piece and the connecting piece 3 is enlarged, the strength of the assembly structure is improved, and the situation that the first wing piece 12 and the second wing piece 22 are easily broken and damaged due to stressed vibration can be avoided as much as possible; the locking structure between the well cover 1 and the well cover seat 2 has high strength and longer service life.
The connecting piece 3 of the invention is a C-shaped connecting piece (refer to figure 5); the C-shaped connector may securely lock the first and second tabs 12, 22 together.
The included angle between the upper pressing part 31 and the lower pressing part 32 of the present invention and the connecting part 33 is less than or equal to 90 °; the fastening of the upper and lower pressed portions 31, 32 to the top surface of the first wing 12 and the bottom surface of the second wing 22 can be made stronger.
The upper pressing part 31 and the lower pressing part 32 of the present invention form a horn opening at one end far from the connecting part 33; the horn opening is convenient for the upper pressing part 31 to be clamped on the top surface of the first wing 12 and the lower pressing part 32 to be clamped on the bottom surface of the second wing 22 when the connecting piece 3 moves from the first station to the second station, so that the assembly is smoother.
The first wing 12 and the second wing 22 of the present invention have a space therebetween, and the connector 3 has a spacer 34 interposed in the space; the spacing part 34 is inserted in the interval between the first wing piece 12 and the second wing piece 22, so that the situation that the first wing piece 12, the second wing piece 22, the upper pressing part 31 and the lower pressing part 32 are broken and damaged due to mutual vibration collision caused by gaps can be avoided, and the installation firmness between the well lid 1 and the well lid seat 2 is improved; the spacer 34 may also act as a cushioning structure to distribute the forces exerted by the first and second fins 12, 22 for cushioning protection.
The connector 3 of the present invention is an E-type connector (refer to fig. 6).
The distance from the top surface of the first wing 12 to the top surface of the well cover 1 is larger than or equal to the thickness of the upper pressing part 31; so that the upper pressing part 31 does not protrude above the well cover 1, the overall structure of the well cover is smoother, and the vehicle is more stable when rolling.
The bottom surface of the first wing panel 12 is flush with the bottom surface of the well cover 1, so that the bottom surface of the well cover 1 is smooth, stacking and transportation are convenient, and production cost is reduced.
The first wing 12 and the second wing 22 of the invention are far away from the center of the manhole cover, the first channel 13 and the second channel 23 are close to the center of the manhole cover, and the connecting piece 3 is moved from the first station to the second station and is transversely pushed from the center of the manhole cover to the edge of the manhole cover (please see fig. 3 for details); or the first wing piece 12 and the second wing piece 22 are close to the center of the well cover, the first channel 13 and the second channel 23 are far away from the center of the well cover, and the connecting piece 3 moves from the first station to the second station and is transversely pushed to the center of the well cover from the edge of the well cover; the connecting piece 3 is used for locking the well lid 1 and the well lid seat 2 along the radial movement, so that not only can the locking function be achieved, but also the rotation of the well lid 1 relative to the well lid seat 2 can be limited, and the locking firmness of the well lid 1 relative to the well lid seat 2 is prevented from being influenced by the rotation of the well lid 1 relative to the well lid seat 2.
The manhole cover 1 is provided with a lug part 14, and the first through groove 11 is formed on the lug part 14; the well lid seat 2 is provided with an ear piece groove 24 for clamping the ear piece part 14, and the second through groove 21 is formed on the ear piece groove 24; or the well lid seat 2 is provided with a lug part 24 'protruding out of the top surface of the well lid seat 2, and the second through groove 21 is formed on the lug part 24'; the bottom surface of the well lid 1 is provided with a tab slot 14' for the tab portion 24' to be clamped, and the first through slot 11 is formed on the tab slot 14' (see fig. 4 for details); the mutual matching structure of the lug parts 14 and 24 'and the lug grooves 24 and 14' not only can increase the bearing effect between the well lid 1 and the well lid seat 2, but also can relatively limit the positions of the well lid 1 and the well lid seat 2, and can not rotate at will, so that the locking structure between the well lid 1 and the well lid seat 2 can not be influenced.
The first through groove 11 and the second through groove 12 are elliptical through grooves, arc-shaped through grooves, circular through grooves, other special-shaped through grooves and the like; because the support area between the well lid 1 and the well lid seat 2 is limited, the shapes of the first through groove 11 and the second through groove 12 can be set according to the specific support area between the well lid 1 and the well lid seat 2, and the structure is more compact.
The well lid seat 2 is provided with a support ring 25 sleeved on the inner wall of a well mouth and a support seat 26 supported on the well wall; the well lid seat 2 can be firmly installed with the deep well and the well wall.
The anti-falling anti-impact plate 4 is arranged in the support ring 25 of the well lid seat 2, and the anti-falling anti-impact plate 4 can play a role in safety protection.
The top surface of a supporting seat 26 of the well lid seat 2 is provided with an arc-shaped groove 27, and a buffer cushion 5 is arranged in the arc-shaped groove 27; the buffer cushion 5 is positioned between the well cover and the well cover seat, can be used as a buffer structure of the well cover and the well cover seat, and has a buffer effect when a vehicle rolls.
Rubber blocks are plugged in the first channel 13 and the second channel 23; the rubber blocks fill the first channel 13 and the second channel 23, so that the connecting piece 3 can be prevented from sliding to the first channel 13 and the second channel 23 and being separated from the first wing piece 12 and the second wing piece 22, and the well lid 1 and the well lid seat 2 can not be firmly locked.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
