Description

Technical Field

[0001] The present application relates to the technical field of manhole covers, and in particular to a manhole cover that is easy to settle and quickly replace. Background Art

[0002] Poor construction quality, long road service life, insufficient urban infrastructure construction and maintenance, and natural factors such as earthquakes and heavy rains can cause manhole covers to sink. When manhole covers sink, they may cause a series of safety hazards, such as pedestrians and vehicles getting stuck, getting scratched, and other accidents. They may also cause noise, road collapse, and other problems, seriously affecting the city's appearance, urban landscape, and citizens' lives.

[0003] Application No. 202121676389.3 discloses a manhole cover that is easy to replace and maintain, including a fixed outer ring, a manhole cover, a vertical groove, a positioning groove and an isolation net, etc. By moving the manhole cover up and down and rotating it, the positioning sleeve moves along the limit device, so that the installation of the manhole cover is convenient and quick. After the installation of the manhole cover is completed, the limit shaft passes through the positioning sleeve so that the manhole cover cannot rotate. At the same time, when the manhole cover is pulled directly upward, the positioning sleeve and the top of the inner wall of the positioning groove collide, so that the manhole cover cannot be removed when it is pulled directly upward. The entire manhole cover does not require the use of bolts or clamping equipment, and has a certain anti-theft protection capability.

[0004] However, in use, there are the following defects:

[0005] Although the interference between the positioning sleeve and the positioning groove is used to prevent the manhole cover from being pulled directly upwards to ensure that it cannot be removed, the manhole cover lacks fixation when rotating. Therefore, when encountering external forces such as a thief turning the manhole cover, the positioning sleeve may be detached from the positioning groove, causing the manhole cover to be pulled, thereby affecting the safety and stability of the manhole cover. Utility Model Content

[0006] The purpose of the present application is to provide a manhole cover which is easy to sink and replace quickly, and solves the problem proposed in the background technology that although the interference between the positioning sleeve and the positioning groove is used to prevent the manhole cover from being directly pulled upwards to ensure that it cannot be removed, due to the lack of fixation when the manhole cover rotates, when encountering external force such as a thief turning the manhole cover, the positioning sleeve may be detached from the positioning groove, causing the manhole cover to be pulled, thereby affecting the safety and stability of the manhole cover.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a manhole cover that is easy to sink and quickly replace, comprising a manhole ring, a manhole cover body, an insertion groove, a limit rod and a fixed block, an inner support ring is fixedly connected to the inner lower side of the manhole ring, turning grooves are provided on both sides of the inner ring of the inner support ring, an insertion groove is provided on the upper left side of the turning groove, a limit groove is provided on the right bottom of the turning groove, and the insertion groove and the limit groove are connected to the turning groove, fixed blocks are fixedly installed on the left and right side walls of the manhole cover body, a fixing ring is fixedly connected to the outer wall of the fixing block, and the limit rod is vertically slidably connected to the inner side of the fixing ring, a top groove is provided in the center of the top end of the manhole cover body, and a bottom groove is provided and connected below the top groove.

[0008] In this technical solution, the manhole cover can be prevented from being lifted vertically by the turning groove, the limit groove, the insertion groove and the limit rod, so that the fixed block and the fixed ring are aligned with the insertion groove, and the manhole cover body is lowered. At this time, the fixed block and the fixed ring reach the turning groove, and then the manhole cover body is rotated to the right so that the fixed block and the fixed ring reach the right side of the turning groove. The limit rod will slide into the limit groove under the action of gravity. At this time, the manhole cover body cannot be rotated in the opposite direction due to the obstruction of the limit rod, thereby preventing the manhole cover body from being lifted after rotation, thereby improving the safety and stability of the device. At the same time, the limit rod can be lifted by the cross groove, cross rod, movable block and insertion block, and the movable block can be lifted from the top The groove is slightly lifted, and the movable block drives the plug block below to rise. During the rising process, the plug block will drive the cross bar of the side wall to rise in the cross groove. The other end of the cross bar is connected to the limit rod in the fixed ring, so the limit rod will also be pulled up from the limit groove. At this time, the manhole cover body can be rotated and lifted, which ensures safety and is convenient for disassembly and assembly. At the same time, an anti-settling rod is arranged at the bottom of the inner support ring. If the manhole cover body settles, the plug block will contact the anti-settling rod below and move upward during the extrusion process, thereby driving the cross bar and the limit rod to rise and take out the manhole cover body, which improves the anti-settling performance of the device and the convenience of installation.

[0009] As an optional solution of the technical solution of the present application, a movable block is movably placed inside the top groove, an insert block is fixedly welded at the bottom center of the movable block, and the insert block is located on the inner side of the bottom groove.

[0010] As an optional solution of the technical solution of the present application, transverse grooves are transversely opened on the inner side of the manhole cover body on the left and right sides of the bottom groove.

[0011] As an optional solution of the technical solution of the present application, the side wall of the insert block is fixedly connected to one end of the connecting rod, the other end of the connecting rod is fixedly connected to the side wall of the limiting rod, and the connecting rod is located on the inner side of the transverse groove.

[0012] As an optional solution of the technical solution of the present application, an anti-settling rod is fixedly installed at the bottom of the inner ring of the inner support ring.

[0013] As an optional solution of the technical solution of the present application, one end of the transverse groove is connected to the bottom groove, and the other end of the transverse groove passes through the fixing block and is connected to the fixing ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can prevent the manhole cover from being lifted vertically through the turning groove, the limit groove, the insertion groove and the limit rod. The fixing block and the fixing ring are aligned with the insertion groove, and the manhole cover body is lowered. At this time, the fixing block and the fixing ring reach the turning groove, and then the manhole cover body is rotated to the right so that the fixing block and the fixing ring reach the right side of the turning groove. The limit rod will slide into the limit groove under the action of gravity. At this time, the manhole cover body cannot be rotated in the opposite direction due to the obstruction of the limit rod, thereby preventing the manhole cover body from being lifted after rotation, thereby improving the safety and stability of the device.

[0016] 2. The present application can lift the limit rod through the cross groove, cross bar, movable block and plug-in block. The movable block is slightly lifted from the top groove, and the movable block drives the plug-in block below to rise. During the rising process, the plug-in block will drive the cross bar of the side wall to rise in the cross groove. The other end of the cross bar is connected to the limit rod in the fixed ring, so the limit rod will also be pulled up from the limit groove. At this time, the manhole cover body can be rotated and lifted, which ensures safety and is convenient for disassembly and assembly.

[0017] 3. The present application sets an anti-settling rod at the bottom of the inner support ring. If the manhole cover body settles, the insert block will contact the anti-settling rod below and move upward during the extrusion process, thereby driving the cross bar and the limit rod to rise and remove the manhole cover body, thereby improving the anti-settling performance of the device and the convenience of installation.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, a manhole cover which is convenient for quick replacement due to settlement includes a manhole ring 1, a manhole cover body 3, an insertion groove 13, a limit rod 11 and a fixed block 9. An inner support ring 2 is fixedly connected to the inner lower side of the manhole ring 1, and an anti-settling rod 12 is fixedly installed at the bottom of the inner ring of the inner support ring 2. The anti-settling rod 12 can lift the insertion block 6 when the manhole cover body 3 settles.

[0025] like Figure 2 As shown, turning grooves 14 are provided on both sides of the inner ring of the inner support ring 2, an insertion groove 13 is provided on the upper left side of the turning groove 14, a limiting groove 15 is provided on the right bottom of the turning groove 14, and the insertion groove 13 and the limiting groove 15 are both connected to the turning groove 14. The limiting groove 15 can clamp the limiting rod 11, thereby completing the fixation of the manhole cover body 3.

[0026] like Figure 2 As shown, the left and right side walls of the manhole cover body 3 are fixedly installed with fixing blocks 9, the outer side wall of the fixing block 9 is fixedly connected with a fixing ring 10, and the inner side of the fixing ring 10 is vertically slidably connected with a limit rod 11.

[0027] like Figure 3 As shown, a top groove 4 is opened in the center of the top of the manhole cover body 3, a bottom groove 601 is opened and connected below the top groove 4, a movable block 5 is movably placed inside the top groove 4, an insert block 6 is fixedly welded at the center of the bottom of the movable block 5, and the insert block 6 is located on the inner side of the bottom groove 601. The movable block 5 is heavy to avoid lifting the water overflowing from the sewer.

[0028] like Figure 3 As shown, transverse grooves 7 are transversely opened on the inner side of the manhole cover body 3 on the left and right sides of the bottom groove 601, one end of the transverse groove 7 is connected with the bottom groove 601, the other end of the transverse groove 7 passes through the fixed block 9 and is connected with the fixed ring 10, the side wall of the plug block 6 is fixedly connected with one end of the connecting rod 8, the other end of the connecting rod 8 is fixedly connected with the side wall of the limiting rod 11, the connecting rod 8 is located on the inner side of the transverse groove 7, and the connecting rod 8 can drive the limiting rod 11 to rise together, thereby canceling the limit.

[0029] In actual use, the manhole cover can be prevented from being lifted vertically through the steering groove 14, the limiting groove 15, the insertion groove 13 and the limiting rod 11. The fixing block 9 and the fixing ring 10 are aligned with the insertion groove 13, and the manhole cover body 3 is lowered. At this time, the fixing block 9 and the fixing ring 10 reach the steering groove 14, and then the manhole cover body 3 is rotated to the right, so that the fixing block 9 and the fixing ring 10 reach the right side of the steering groove 14, and the limiting rod 11 will slide into the limiting groove 15 under the action of gravity. At this time, the manhole cover body 3 cannot be rotated in the opposite direction under the obstruction of the limiting rod 11, thereby preventing the manhole cover body 3 from being lifted after rotation, thereby improving the safety and stability of the device. At the same time, the limiting rod 11 can be lifted through the transverse groove 7, the transverse rod, the movable block 5 and the insertion block 6. The movable block 5 is slightly lifted from the top groove 4, and the movable block 5 drives the plug block 6 below to rise. During the rising process, the plug block 6 will drive the cross bar of the side wall to rise in the cross groove 7. The other end of the cross bar is connected to the limit rod 11 in the fixed ring 10, so the limit rod 11 will also be pulled up from the limit groove 15. At this time, the manhole cover body 3 can be rotated and lifted, which ensures safety and is convenient for disassembly and assembly. At the same time, an anti-settling rod 12 is provided at the bottom of the inner support ring 2. If the manhole cover body 3 sinks, the plug block 6 will contact the anti-settling rod 12 below and move upward during the extrusion process, thereby driving the cross bar and the limit rod 11 to rise and take out the manhole cover body 3, thereby improving the anti-settling performance of the device and the convenience of installation.
