Description

Technical Field

[0001] This utility model belongs to the field of manhole cover technology, and in particular relates to a split and assembleable manhole cover base. Background Technology

[0002] Manhole covers are typically used to cover roads or deep wells to prevent people or objects from falling in, while also ensuring the proper functioning of infrastructure such as drainage, cables, and communications. They are widely used in various locations, including cities, rural areas, and industrial zones.

[0003] When installing manhole covers, bases are needed to support and fix the covers. When installing manhole covers on long road sections, many covers need to be installed. To improve the stability between the covers, welding is used to weld and fix multiple manhole cover bases together. Welding and fixing multiple covers together takes a long time, reducing work efficiency. Furthermore, if damage occurs and repairs are needed, the welded bases are inconvenient to disassemble and replace. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a split and assemblable manhole cover base that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a split, assemblable manhole cover base includes a base and a fixing assembly. The base includes a frame, a support plate, a connecting plate, and two fixing blocks. The top of the support plate is fixedly connected to the bottom of the frame, and the left side of the connecting plate is fixedly connected to the right side of the frame. The tops of the two fixing blocks are respectively fixedly connected to the front and rear sides of the bottom of the connecting plate. The fixing assembly includes a fixing frame, two connecting blocks, multiple inserts, and two connecting shafts. The surface of the fixing frame is fixedly connected to the left side of the interior of the frame. The surfaces of the two connecting blocks are respectively fixedly connected to the front and rear sides of the interior of the fixing frame. The sides of the multiple inserts near the two connecting blocks are respectively fixedly connected to the opposite sides of the two connecting blocks. The surfaces of the multiple inserts are respectively movably connected to the front and rear sides of the interior of the fixing frame. The sides of the two connecting shafts near the two connecting blocks are both fixedly connected to the interior of the two connecting blocks.

[0006] The base is used to install the manhole cover;

[0007] The fixing component is used to assemble and connect multiple bases.

[0008] To facilitate the assembly of multiple bases, preferably, a support ring is fixedly connected to the top of the support plate, the surface of the support ring is fixedly connected to the inside of the frame, and a connecting component is provided inside the fixed frame. When assembling the base, the fixing block is inserted into the frame of the assembled base, and the movement of the fixing block is restricted by the insertion of the insert block into the inside of the fixing block, thereby making the base assembly stable.

[0009] To facilitate the movement of the two connecting blocks, preferably, the connecting assembly includes a connector, two fixed shafts, and two connecting rods. The connector is located inside the fixed frame. The two fixed shafts are fixedly connected to the left and right sides of the connector's interior, respectively, on the side closest to the connector. The opposite ends of the two connecting rods are movably connected to the surfaces of the two fixed shafts, and the opposite sides of the two connecting rods are movably connected to the surfaces of the two connecting shafts. By moving the connector downwards, the two connecting rods move via the two fixed shafts, and the two connecting rods move via the two connecting shafts.

[0010] To prevent the connector from tilting, preferably, a limiting plate is slidably connected inside the connector. The top of the limiting plate is fixedly connected to the top of the inside of the fixed frame, and the bottom of the limiting plate is fixedly connected to the bottom of the inside of the fixed frame. The limiting plate restricts the movement direction of the connector and prevents the connector from tilting or shifting.

[0011] To facilitate the movement of the connector, preferably, a lower pressure plate is fixedly connected to the right side of the connector. The surface of the lower pressure plate is movably connected to the interior of the frame, and the right side of the surface of the lower pressure plate is movably connected to the interior of the support ring. After the manhole cover is installed, the manhole cover presses down on the lower pressure plate, which in turn drives the connector to move.

[0012] To disengage the insert block from the fixing block, preferably, a return spring is fixedly connected inside each of the two connecting blocks. The opposite ends of the two return springs are fixedly connected to the front and rear sides inside the fixing frame, respectively. The return of the two return springs causes the two connecting blocks to move towards the opposite ends, and the movement of the two connecting blocks causes the two insert blocks to move.

[0013] To limit the movement distance of the two connecting blocks, preferably, two limiting rods are fixedly connected to both the front and rear sides inside the fixed frame. The four limiting rods block the two connecting blocks and limit their movement distance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model achieves the effect of conveniently splicing and assembling multiple manhole cover bases by setting up structural components such as base, frame, support plate and connecting plate, installing manhole covers on the base, assembling and connecting multiple bases through fixing components, driving the connecting block to move through the connecting components, limiting the movement direction of the connecting components through the limiting plate, and disengaging the insert block from the fixing block through the return spring.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 4As shown in the figure, this utility model provides a split-assembly manhole cover base, including a base 1 and a fixing component 2. The base 1 includes a frame 101, a support plate 102, a connecting plate 103, and two fixing blocks 104. The top of the support plate 102 is fixedly connected to the bottom of the frame 101, the left side of the connecting plate 103 is fixedly connected to the right side of the frame 101, and the tops of the two fixing blocks 104 are respectively fixedly connected to the front and rear bottoms of the connecting plate 103. The fixing component 2 includes a fixing frame 201, two connecting blocks 202, multiple insert blocks 203, and two connecting... The connecting shaft 204 and the surface of the fixed frame 201 are fixedly connected to the left side of the interior of the frame 101. The surfaces of the two connecting blocks 202 are fixedly connected to the front and rear sides of the interior of the fixed frame 201, respectively. The sides of the multiple inserts 203 near the two connecting blocks 202 are fixedly connected to the opposite sides of the two connecting blocks 202, respectively. The surfaces of the multiple inserts 203 are movably connected to the front and rear sides of the interior of the fixed frame 201, respectively. The sides of the two connecting shafts 204 near the two connecting blocks 202 are fixedly connected to the interior of the two connecting blocks 202. The base 1 is used to install the manhole cover.The fixing component 2 is used to assemble and connect multiple bases 1. To facilitate the assembly of multiple bases 1, a support ring 3 is fixedly connected to the top of the support plate 102. The surface of the support ring 3 is fixedly connected to the inside of the frame 101. A connecting component 4 is provided inside the fixing frame 201. When assembling the bases 1, the fixing block 104 is inserted into the frame 101 of the assembly base 1. The insertion block 203 is inserted into the fixing block 104 to restrict the movement of the fixing block 104, thereby stabilizing the assembly of the bases 1. To facilitate the movement of the two connecting blocks 202, the connecting component 4 includes a connector 401, two fixed shafts 402, and two connecting rods 403. Component 401 is located inside the fixed frame 201. Two fixed shafts 402 are fixedly connected to the left and right sides of the connector 401 on the side closest to the connector 401, respectively. The opposite ends of the two connecting rods 403 are movably connected to the surfaces of the two fixed shafts 402, and the opposite sides of the two connecting rods 403 are movably connected to the surfaces of the two connecting shafts 204. By moving the connector 401 downwards, the two connecting rods 403 move via the two fixed shafts 402. During the movement of the two connecting rods 403, the two connecting blocks 202 are pushed to move via the two connecting shafts 204. To prevent the connector 401 from tilting... A limiting plate 5 is slidably connected inside the connector 401. The top of the limiting plate 5 is fixedly connected to the top of the inside of the fixed frame 201, and the bottom of the limiting plate 5 is fixedly connected to the bottom of the inside of the fixed frame 201. The limiting plate 5 restricts the movement direction of the connector 401 to prevent the connector 401 from tilting or shifting. To facilitate the movement of the connector 401, a lower pressure plate 6 is fixedly connected to the right side of the connector 401. The surface of the lower pressure plate 6 is movably connected to the inside of the frame 101, and the right side of the surface of the lower pressure plate 6 is movably connected to the inside of the support ring 3. After the manhole cover is installed, the manhole cover presses down on the lower pressure plate 6, which in turn moves the connector 401. To disengage the insert block 203 from the fixed block 104, a return spring 7 is fixedly connected inside each of the two connecting blocks 202. The opposite ends of the two return springs 7 are fixedly connected to the front and rear sides of the fixed frame 201, respectively. The return of the two return springs 7 causes the two connecting blocks 202 to move towards their opposite ends. During this movement, the two connecting blocks 202 also move the two insert blocks 203. To limit the movement distance of the two connecting blocks 202, two limiting rods 8 are fixedly connected to the front and rear sides of the fixed frame 201. These four limiting rods 8 block the two connecting blocks 202, thus limiting their movement distance.

[0024] The working principle of this utility model:

[0025] When assembling multiple bases 1, fixing blocks 104 are inserted into the frames 101 of adjacent bases 1, and manhole covers are installed inside the frames 101. The manhole covers press down on the lower pressure plate 6, causing the lower pressure plate 6 to move downward. During the movement of the lower pressure plate 6, the connecting piece 401 moves downward. During the movement of the connecting piece 401, two connecting rods 403 are moved through two fixing shafts 402. During the movement of the two connecting rods 403, two connecting blocks 202 are pushed to move to opposite sides through two connecting shafts 204. During the movement of the two connecting blocks 202, multiple inserts 203 are inserted into the interior of the two fixing blocks 104, restricting the movement of the fixing blocks 104 and making the fixing blocks 104 and the frame 101 fixed and stable, thereby making the multiple bases 1 stably assembled.
