Description

Technical Field

[0001] This utility model relates to the field of road maintenance manhole cover technology, and in particular to a reinforced manhole cover that prevents loosening. Background Technology

[0002] As an important part of urban infrastructure, manhole covers are widely used in the inspection wells of drainage, sewage, electricity, and communication pipelines in municipal roads, residential areas, public green spaces, and other places.

[0003] A search revealed Chinese patent CN203795474U, which discloses an anti-loosening reinforced manhole cover, including a manhole base, a manhole cover, and a handle. The manhole cover is mounted on the manhole base, and both the manhole base and the manhole cover are circular. A protruding neck is provided at the connection between the manhole base and the manhole cover, and the manhole cover is installed in the protruding neck on the manhole base. This manhole cover, through the snap-fit ​​opening and snap-fit ​​groove on the manhole cover and the snap-fit ​​on the manhole base, can effectively prevent the manhole cover from loosening and avoid loss. The load-bearing reinforcing ribs at the bottom of the manhole cover are distributed in a grid pattern, which can effectively play a load-bearing role.

[0004] However, the manhole cover still has the following problems: the manhole cover only uses the buckle opening and groove on the cover to connect with the buckle on the base, so that the cover and the base are locked together. The structure is relatively simple. In actual use, under the frequent running over by vehicles, the buckle opening and the buckle are prone to displacement, resulting in loosening, which makes it difficult to effectively improve the safety of the manhole cover. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-loosening reinforced manhole cover.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reinforced manhole cover designed to prevent loosening includes a base, a cover plate disposed on top of the base, a filter pipe fixedly connected to one end of the cover plate, a pair of handle holes on both sides of the top of the cover plate, and a locking assembly and a connecting assembly disposed below the cover plate.

[0008] The locking assembly includes a pair of limiting blocks fixedly connected to both sides of the bottom of the cover plate. Each limiting block has a locking groove at one end. The top two sides of the base have a pair of limiting grooves that match the limiting blocks. The outer peripheral wall of the base has a pair of sliding grooves near the limiting grooves. The inner wall of each sliding groove is slidably connected to a locking block that matches the locking groove. One end of each locking block is fixedly connected to a connecting block. Both ends of each connecting block are rotatably connected to a rotating rod via a rotating shaft. One end of the pair of rotating rods is fixedly connected to a connecting rod. When the cover plate is placed in position, the locking block can be driven to move along the sliding groove by operating the connecting rod, so that it is locked into the locking groove of the limiting block. This rigid locking method fundamentally avoids the displacement of the cover plate in the vertical and horizontal directions, effectively resists the vibration and impact generated by vehicle rolling, and completely eliminates the risk of the manhole cover loosening and jumping.

[0009] Preferably, a pair of placement slots are provided on the top of the base near the limiting groove, and the placement slots are adapted to the rotating rod and the connecting rod. The placement slots provide dedicated accommodating space for the rotating rod and the connecting rod.

[0010] Preferably, a guide rod is slidably connected to one end of the placement groove, and a spring is sleeved between the outer peripheral wall of the guide rod and the placement groove.

[0011] Preferably, a pair of sealing grooves adapted to the placement groove are provided on the top of the cover plate away from the handle hole, and a sealing plate is snapped into one end of each sealing groove.

[0012] Preferably, the connecting component includes a slot formed in the top of the base, and a set of locking blocks adapted to the slot are fixedly connected to the bottom edge of the cover plate.

[0013] Preferably, each of the card blocks is arranged in an inverted L-shape, and a group of card blocks are evenly distributed. The inverted L-shape structure makes the card blocks form a hook effect in the vertical direction, which can provide a certain anti-tipping and anti-falling ability even when not fully locked.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the cooperation between the connecting rod, the rotating rod, and the connecting block, the locking block is driven to rotate along the sliding groove, so that the locking block and the locking groove are engaged with each other. Through the cooperation between the locking block and the locking groove, the cover plate and the base are locked together, preventing the cover plate from loosening or even tilting up at one end due to external force, thus effectively improving the safety of the manhole cover.

[0016] 2. When the cover needs to be repaired or replaced, a pair of sealing plates are removed. Then, through the cooperation between the guide rod and the spring, the connecting rod is driven upward to disengage from the placement groove, making it easier for workers to pull the connecting rod and effectively improving the convenience of the manhole cover.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1-4 A reinforced manhole cover designed to prevent loosening includes a base 1, with a cover plate 2 mounted on top of the base 1. Both the base 1 and the cover plate 2 are made of concrete, which enhances the overall structural strength of the manhole cover. One end of the cover plate 2 is fixedly connected to a filter pipe 3, which filters out garbage and prevents it from entering and clogging the sewer network. A pair of handle holes 4 are provided on both sides of the top of the cover plate 2, which facilitates lifting the cover plate 2. The cover plate 2 also includes a locking assembly and a connecting assembly located below it.

[0024] like Figures 2-4As shown, in one embodiment, the locking assembly includes a pair of limiting blocks 7 fixedly connected to the bottom sides of the cover plate 2. Each limiting block 7 has a locking groove 701 at one end. The top sides of the base 1 have a pair of limiting grooves 8 that are adapted to the limiting blocks 7. The cover plate 2 is limited by the mutual cooperation between the limiting blocks 7 and the limiting grooves 8. The outer peripheral wall of the base 1 has a pair of sliding grooves 9 near the limiting grooves 8. The inner wall of each sliding groove 9 is slidably connected to a locking block 1 that is adapted to the locking groove 701. 0. Through the mutual cooperation between the locking block 10 and the locking groove 701, the cover plate 2 and the base 1 are locked together, preventing the cover plate 2 from loosening or even tilting up at one end due to external force, thus effectively improving the safety of the manhole cover. Each locking block 10 has a connecting block 11 fixedly connected to one end, and each connecting block 11 has a rotating rod 12 rotatably connected to both ends through a rotating shaft. One end of a pair of rotating rods 12 is fixedly connected to a connecting rod 13. Through the mutual cooperation between the connecting rod 13, the rotating rod 12, and the connecting block 11, The locking block 10 is rotated along the sliding groove 9 to facilitate quick assembly and disassembly between the locking block 10 and the locking groove 701. A pair of placement grooves 18 are provided on the top of the base 1 near the limiting groove 8, and these placement grooves 18 are adapted to the rotating rod 12 and the connecting rod 13. The placement grooves 18 facilitate the rotation of the rotating rod 12 and the connecting rod 13 within the base 1, avoiding interference with the mutual locking between the cover plate 2 and the base 1. A guide rod 14 is slidably connected to one end of each placement groove 18. A spring 15 is fitted between the outer peripheral wall of the guide rod 14 and the placement groove 18. Through the cooperation between the guide rod 14 and the spring 15, it is easy to drive the connecting rod 13 away from the placement groove 18, so that the operator can easily pull the connecting rod 13. A pair of sealing grooves 16 adapted to the placement groove 18 are opened at the top of the cover plate 2 away from the handle hole 4. A sealing plate 17 is engaged at one end of each sealing groove 16. The sealing plate 17 presses the connecting rod 13, and then the connecting rod 13 drives the guide rod 14 to slide downward.

[0025] like Figure 1 and Figure 2 As shown, in one embodiment, the connecting component includes a slot 5 formed in the top of the base 1, and a set of locking blocks 6 adapted to the slot 5 are fixedly connected to the bottom edge of the cover plate 2. Each locking block 6 is arranged in an inverted L-shape, and the set of locking blocks 6 are evenly distributed. Through the mutual cooperation between the slot 5 and the locking blocks 6, the base 1 and the cover plate 2 are initially connected and fixed to each other.

[0026] Working principle: In use, first install the base 1 in the designated position, then move the cover plate 2 above the base 1 through the handle hole 4. The base 1 and cover plate 2 are initially fixed together by the cooperation between the slot 5 and the block 6. Then, the cover plate 2 is further limited by the cooperation between the limiting block 7 and the limiting groove 8. Next, rotate the connecting rod 13. Through the cooperation between the connecting rod 13, the rotating rod 12, and the connecting block 11, the locking block 10 rotates along the sliding groove 9, causing the locking block 10 to engage with the locking groove 701. Through the cooperation between the locking block 10 and the locking groove 701, the cover plate 2 and the base 1 are locked together, preventing external interference. The force causes the cover plate 2 to loosen or even tilt up at one end, effectively improving the safety of the manhole cover. Then, a pair of sealing plates 17 are snapped into the sealing groove 16. The sealing plates 17 press the connecting rod 13, causing the connecting rod 13 and the rotating rod 12 to rotate into the placement groove 18. This causes the guide rod 14 to drive the spring 15 to compress downwards, preventing damage to the rotating rod 12 and the connecting rod 13 caused by external force. When the cover plate 2 needs to be repaired or replaced, the pair of sealing plates 17 are removed. Then, through the cooperation between the guide rod 14 and the spring 15, the connecting rod 13 is driven upwards out of the placement groove 18, making it easier for workers to pull the connecting rod 13, effectively improving the convenience of the manhole cover.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
