[0007] To achieve the above objectives, this utility model provides the following technical solution: a manhole cover with a concealed lifting hole, comprising: a manhole opening, and a manhole cover body disposed inside the manhole opening, wherein a shock-absorbing ring is disposed on the outer side of the manhole cover body;

[0008] Also includes:

[0009] The manhole cover top plate is installed on the upper side of the manhole cover body, and a second support frame is installed inside the manhole cover body. An interception component is provided inside the manhole cover top plate. A first reinforcing rod is provided inside the second support frame, and a second reinforcing rod is installed at the lower end of the first reinforcing rod. A connecting block is provided on the outer side of the second support frame.

[0010] A support rod is installed on the outside of the manhole cover body, and a lifting handle is connected to the lower end of the support rod. A locking block is installed on the outside of the lifting handle, and a drive rod passes through the middle of the locking block. A first drive disc is provided on the outside of the drive rod, and a second drive disc is connected to the upper side of the first drive disc. A drive block is provided on the upper side of the second drive disc. A guide block is provided inside the locking block, and a guide rod is connected to the inner side of the guide block.

[0011] In one possible scenario, the connecting block is engaged with the manhole cover body, and the cross-section of the connecting block is a "T" shaped structure.

[0012] In one possible scenario, the first and second reinforcing rods are arranged at equal intervals inside the second support frame.

[0013] In one possible implementation, the lifting handle is rotatably connected to the support rod, and the locking block is engaged with the lifting handle.

[0014] In one possible implementation, the drive rod is threadedly connected to the locking block, and the locking block is slidably connected to the guide rod.

[0016] In one possible implementation, the interception assembly includes a limiting rod extending through the outer side of the manhole cover top plate, and an anti-slip groove is provided on the upper surface of the manhole cover top plate. A positioning block is provided at the lower end of the manhole cover top plate, and a first support frame is connected to the inner side of the positioning block. A trapping net is provided in the middle of the first support frame.

[0017] The limiting rod is threadedly connected to both the top plate of the manhole cover and the body of the manhole cover, and anti-slip grooves are equally spaced on the upper surface of the top plate of the manhole cover.

[0018] In one possible scenario, the first support frame is engaged with the positioning block, and the first support frame is evenly spaced at the lower end of the manhole cover top plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the concealed lifting hole manhole cover facilitates the concealment of the lifting hole during the use of the device, making it less likely for foreign objects such as sticks or keys to pry the device during use, thus avoiding affecting the safety of the device and reducing the risk of theft. At the same time, the device has an effective anti-slip and drainage structure inside, making it less likely for people to slip and fall due to low friction when stepping on the device, resulting in a better user experience, as detailed below:

[0020] 1. The first and second reinforcing rods are fixed to the lower end of the manhole cover body by connecting the block and the second support frame, so that the first and second reinforcing rods reinforce and support the manhole cover body, preventing the manhole cover body from deforming due to pressure during use and improving the strength of the device.

[0021] 2. The drive block, in conjunction with the second drive disc, pushes the first drive disc and drive rod to rotate on the outside of the manhole cover body. This causes the drive rod to push the locking block to move inward along the guide rod and engage with the second support frame. This prevents the lifting handle from rotating along the support rod due to the push of foreign objects during use. As a result, the device is less likely to be pried open by foreign objects such as sticks or keys during use, thus preventing thieves from stealing the device by rotating the lifting handle and improving the safety of the device.

[0022] 3. By using the manhole cover body in conjunction with the limiting rod to install the top plate of the manhole, the anti-slip groove greatly improves the irregularity of the upper surface of the top plate of the manhole cover. At this time, the friction between pedestrians, vehicle tires or shoe soles and the top plate of the manhole cover is greatly increased. Especially in rainy, snowy or oily weather, it can effectively reduce the risk of slipping and falling. At the same time, the interception net installed at the lower end of the top plate of the manhole cover intercepts materials carried by rainwater, preventing valuables such as mobile phones and rings from falling into the underground drainage system through the drainage channel, thus improving the effectiveness of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a manhole cover with a hidden lifting hole, including a manhole opening 1, a manhole cover body 2, a shock-absorbing ring 3, a manhole cover top plate 4, a limiting rod 5, an anti-slip groove 6, a positioning block 7, a first support frame 8, a trap net 9, a second support frame 10, a first reinforcing rod 11, a second reinforcing rod 12, a connecting block 13, a support rod 14, a lifting handle 15, a locking block 16, a drive rod 17, a first drive disc 18, a guide block 19, a guide rod 20, a second drive disc 21, and a drive block 22.

[0031] Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, before the device is used, the second support frame 10 is installed inside the manhole cover body 2. Due to the engaging connection structure between the connecting block 13 and the manhole cover body 2, the connecting block 13 effectively and stably confines the second support frame 10, the first reinforcing rod 11, and the second reinforcing rod 12 inside the manhole cover body 2. Because the first reinforcing rod 11 and the second reinforcing rod 12 are equally spaced inside the second support frame 10, they form a mesh-like reinforcement structure inside the second support frame 10. The first reinforcing rod 11... The second reinforcing rod 12 reinforces and supports the manhole cover body 2, preventing deformation due to pressure during use and improving the strength of the device. The manhole cover body 2 and the shock-absorbing ring 3 are then hoisted and placed inside the manhole opening 1 using the lifting handle 15. Due to the rotating connection between the lifting handle 15 and the support rod 14, the lifting handle 15 rotates downwards into the manhole cover body 2 when it is no longer pulled. A special key is then inserted into the drive block 22, allowing the operator to easily rotate the drive block 22 and the second drive disc 21. Because of the threaded connection between the second drive disc 21 and the first drive disc 18, the second drive disc 21 can effectively push the first drive disc 18 and the drive rod 17 to rotate inside the manhole cover body 2 during rotation. Due to the threaded connection between the drive rod 17 and the locking block 16, the drive rod 17 can effectively push the locking block 16 connected to its inner side to move inward during rotation. At this time, because of the sliding connection between the locking block 16, the guide block 19, and the guide rod 20, the locking block 16 and the guide block 19 are subjected to the force of the guide rod 20 during their inward displacement. The guide limit at 0 prevents the locking block 16 and guide block 19 from shifting position during inward movement. Due to the engaging connection between the locking block 16 and the lifting handle 15, the locking block 16 engages with the lifting handle 15 during inward movement, preventing the lifting handle 15 from rotating along the support rod 14 due to external objects. This makes it less likely for foreign objects such as sticks or keys to pry the lifting handle 15 during use, thus preventing thieves from stealing the device by rotating the lifting handle 15 and improving the security of the device.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, during the use of the device, the engaging connection between the first support frame 8 and the positioning block 7 allows the operator to easily install the first support frame 8 on the lower side of the manhole cover top plate 4. At this time, the first support frame 8 stably fixes the intercepting mesh 9 to the lower end of the manhole cover top plate 4. By installing the manhole cover top plate 4 on the upper side of the manhole cover body 2, and simultaneously rotating the limiting rod 5 penetrating the outer side of the manhole cover top plate 4, the threaded connection between the limiting rod 5 and the manhole cover top plate 4 and the manhole cover body 2 allows the downward-rotating limiting rod 5 to effectively connect the manhole cover top plate 4 and the manhole cover body 2 together. At this time, the manhole cover top plate 4 protects the upper side of the manhole cover body 2. The operator can pass over the upper surface of the manhole cover body 2. When people step on the top plate 4 of the manhole cover, the irregularity of the top surface of the manhole cover 4 is greatly increased because the anti-slip grooves 6 are evenly spaced on the upper surface of the manhole cover 4. This greatly increases the friction when pedestrians, vehicle tires or shoe soles come into contact with the top plate 4. Especially in rainy, snowy or oily weather, this can effectively reduce the risk of slipping and falling. At the same time, in rainy weather, the water on the road falls into the underground drainage system through the drainage channel opened inside the top plate 4. The interception net 9 set on the lower side of the top plate 4 intercepts the materials carried by the rainwater, preventing valuables such as mobile phones and rings from falling into the underground drainage system through the drainage channel, thus improving the effectiveness of the device.
