Description
Technical Field
[0001] This utility model relates to the field of manhole cover technology, specifically to an anti-settlement municipal manhole cover. Background Technology
[0002] Municipal manhole covers, as an important part of urban infrastructure, are widely used in urban roads, sidewalks and other places to cover facilities such as sewers and inspection wells, ensuring road passage while also facilitating the inspection and maintenance of underground facilities.
[0003] In actual use, most manhole covers are directly snapped onto the manhole base. The manhole surface is subjected to repeated crushing by passing vehicles and frequent trampling by pedestrians over a long period of time. The connection between the manhole cover and the manhole base is prone to loosening, which can lead to settlement and displacement. Therefore, it is necessary to design an anti-settlement municipal manhole cover to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-settlement municipal manhole cover to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a municipal manhole cover for preventing settlement, comprising a manhole base and a manhole cover, wherein a support plate is installed at the bottom of the interior of the manhole base, and a circular baffle is provided at the bottom of the manhole cover. When the manhole cover is engaged inside the manhole base, the circular baffle abuts against the top of the support plate, and a limiting component is provided between the interior of the manhole base and the circular baffle.
[0006] The well base has multiple sets of movable cavities arranged in a ring inside. The bottom of each set of movable cavities is connected to a support rod. The outer sides of each set of support rods are connected to a locking plate by bearings. The outer sides of the circular baffle are provided with locking grooves.
[0007] Preferably, the limiting component includes a convex block and a limiting groove. Two sets of convex blocks are circumferentially installed on the outer bottom of the circular baffle. Two sets of limiting grooves are respectively circumferentially opened at both ends of the well seat, and the convex blocks are slidably connected in the limiting grooves.
[0008] Preferably, the bottom of the circular baffle is provided with a fitting groove, and when the bottom of the fitting groove presses against the bottom of the multiple sets of locking plates, the circular baffle abuts against and fits against the top of the support plate.
[0009] Preferably, each of the multiple sets of locking plates has a weight block at one end of its top, and the multiple sets of weight blocks increase the weight of the top of the locking plate.
[0010] Preferably, the top two ends of the manhole cover are provided with ventilation grooves to drain water into the manhole seat.
[0011] Preferably, multiple sets of stabilizing plates are installed in a ring around the outer side of the well base, and the multiple sets of stabilizing plates surround the outer side of the well base to reinforce the well base.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By engaging the manhole cover within the manhole base, a circular baffle at the bottom of the manhole cover presses against a support plate installed inside the manhole base. Simultaneously, the weight of the circular baffle and the manhole cover itself presses down on multiple sets of engaging plates movable within the manhole base. The engaging plates rotate along the support rod connected within the movable cavity, causing the top of the engaging plate to engage in a corresponding engaging groove on the outside of the circular baffle. This achieves a stable connection between the manhole cover and the manhole base, effectively preventing the manhole cover from settling or shifting. A weight block is installed at one end of the top of the engaging plate. When the circular baffle detaches from the engaging plate, the weight of the weight block drives the engaging plate to reset.
[0014] 2. The circular baffle is engaged within the well base, and the convex block installed on the outside of the circular baffle slides into the limiting groove opened inside the well base, so that the engaging plate and the engaging groove are in contact. The bottom of the circular baffle is opened into the fitting groove, and the bottom of the fitting groove presses against the bottom of multiple sets of engaging plates. The circular baffle abuts against and fits against the top of the support plate. Attached Figure Description

[0019] 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.
[0020] Example 1
[0021] Please refer to Figure 1-3As shown, this utility model provides an anti-settlement municipal manhole cover, including a manhole base 1 and a manhole cover 12. A support plate 2 is installed at the bottom of the interior of the manhole base 1, and a circular baffle 3 is provided at the bottom of the manhole cover 12. When the manhole cover 12 is engaged inside the manhole base 1, the circular baffle 3 abuts against the top of the support plate 2. A limiting component is provided between the interior of the manhole base 1 and the circular baffle 3.
[0022] The well base 1 has multiple sets of movable cavities 5 arranged in a ring inside. The bottom of each set of movable cavities 5 is connected to a support rod 6. The outer sides of each set of support rods 6 are connected to a locking plate 7 by bearings. The outer sides of the circular baffle 3 are provided with locking grooves 8.
[0023] Specifically, by engaging the manhole cover 12 within the manhole base 1, the circular baffle 3 at the bottom of the manhole cover 12 abuts against the support plate 2 installed inside the manhole base 1. At the same time, the weight of the circular baffle 3 and the manhole cover 12 itself presses down on multiple sets of engaging plates 7 that are movably installed inside the manhole base 1. The engaging plates 7 rotate along the support rod 6 connected inside the movable cavity 5, so that the top of the engaging plates 7 engages in the corresponding engaging groove 8 opened on the outside of the circular baffle 3, thus completing the fixation of the manhole cover 12.
[0024] The limiting component includes a convex block 10 and a limiting groove 11. Two sets of convex blocks 10 are annularly installed on the outer bottom of the circular baffle 3. Two sets of limiting grooves 11 are respectively annularly opened at both ends of the well base 1, and the convex blocks 10 are slidably connected in the limiting grooves 11. They are engaged in the well base 1 by the circular baffle 3. The convex blocks 10 installed on the outer side of the circular baffle 3 are slidably connected in the limiting grooves 11 opened inside the well base 1, so that the engaging plate 7 and the engaging groove 8 are in contact.
[0025] Wherein: the bottom of the circular baffle 3 is provided with a fitting groove 4. When the bottom of the fitting groove 4 presses against the bottom of the multiple sets of locking plates 7, the circular baffle 3 abuts against and fits against the top of the support plate 2. Through the fitting groove 4 provided at the bottom of the circular baffle 3, the bottom of the fitting groove 4 presses against the bottom of the multiple sets of locking plates 7, and at the same time the circular baffle 3 abuts against and fits against the top of the support plate 2.
[0026] Among them, each of the multiple sets of locking plates 7 has a weight block 9 at one end of its top. The multiple sets of weight blocks 9 increase the weight of the top of the locking plate 7. By using the weight blocks 9 at one end of the top of the locking plate 7, when the circular baffle 3 is disengaged from the locking plate 7, the weight of the weight blocks 9 drives the locking plate 7 to reset.
[0027] Wherein: Ventilation grooves 13 are opened at both ends of the top of the manhole cover 12 to drain water into the manhole base 1, and water from the ground is drained into the manhole base 1 through the ventilation grooves 13 opened in the manhole cover 12.
[0028] Among them: multiple sets of stabilizing plates 14 are installed in a ring around the outside of the well seat 1 to reinforce the well seat 1. The well seat 1 is reinforced by multiple sets of stabilizing plates 14 installed in a ring around the outside of the well seat 1.
[0029] Working principle: This utility model provides an anti-settlement municipal manhole cover. In use, the manhole cover 12 is snapped into the manhole base 1. The circular baffle 3 at the bottom of the manhole cover 12 abuts against the support plate 2 installed inside the manhole base 1. At the same time, the weight of the circular baffle 3 and the manhole cover 12 itself presses down on multiple sets of snapping plates 7 that are movably installed inside the manhole base 1. The snapping plates 7 are flipped along the support rod 6 connected in the movable cavity 5, so that the top of the snapping plate 7 snaps into the corresponding snapping groove 8 opened on the outside of the circular baffle 3, thus fixing the manhole cover 12. At the same time, the convex block 10 installed on the outside of the circular baffle 3 is slidably connected to the limiting groove 11 opened inside the manhole base 1, so that the snapping plate 7 and the snapping groove 8 are in contact. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
