Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a temporary construction manhole cover that is easy to install and disassemble. Background Technology

[0002] In engineering scenarios such as building construction, municipal road maintenance, and underground pipeline laying, temporary construction manhole covers must be used to temporarily cover the manhole openings before the formal manhole covers are installed. This is to prevent people from falling in, construction materials or debris from falling into the manholes, and to ensure temporary passage safety in the construction area.

[0003] Existing temporary manhole covers mostly rely on bolts for fixing, which require the use of wrenches and other tools to tighten them one by one. This process is time-consuming and cannot meet the needs of frequently opening manholes during construction. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a construction temporary manhole cover that is easy to install and disassemble, aiming to improve the problem that existing temporary manhole covers mostly rely on bolt fixing and require tools such as wrenches to tighten them one by one, which is time-consuming to install and disassemble.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A temporary construction manhole cover that is easy to install and disassemble includes a manhole cover body, a manhole seat on the outside of the manhole cover body, a positioning block fixedly connected to the outside of the manhole cover body, a positioning groove inside the manhole seat, the outside of the positioning block being disposed inside the positioning groove, a locking block fixedly connected to the outside of the manhole cover body, a locking groove inside the manhole seat, the outside of the locking block being disposed inside the locking groove, and a locking component on the outside of the manhole seat.

[0006] The above technical solution utilizes the positioning block of the manhole cover body and the positioning groove of the manhole seat to achieve rapid positioning of the manhole cover body. The initial positioning of the manhole cover body and the manhole seat is achieved through the cooperation of the locking block and the locking groove. Then, the two are further fixed by the locking component to prevent the manhole cover body from shifting or falling off during construction. Moreover, disassembly and assembly can be completed without complicated tools, ensuring the safety of the manhole opening while adapting to the high-frequency disassembly and assembly needs during construction and improving operational efficiency.

[0007] Preferably, the locking assembly includes a housing, the outer side of which is fixedly connected to the outer side of the well base, a first spring is provided inside the housing, one end of the first spring is provided with a sliding ring, the outer side of the sliding ring is slidably connected to the inner side of the housing, a sliding rod is fixedly connected inside the sliding ring, a handle is fixedly connected to the top of the sliding ring, the outer side of the handle is slidably connected to the inner side of the housing, the outer side of the sliding rod is engaged inside the locking block, and the outer side of the sliding rod is slidably connected to the inner side of the well base and the housing.

[0008] Preferably, the locking assembly further includes a second spring, the exterior of which is disposed inside the well base, and driving blocks are disposed at both ends of the second spring. A buckle is fixedly connected to the top end of the driving block, and a slider is fixedly connected to the bottom end of the driving block. A first sliding groove is provided inside the well base.

[0009] Preferably, the external sliding connection of the drive block is to the inside of the well base, the external sliding connection of the slider is to the inside of the first sliding groove, the internal opening of the locking block is a limiting groove, and the external engagement of the buckle is engaged with the limiting groove and the inside of the well base.

[0010] Preferably, the manhole cover body has a water inlet inside.

[0011] Preferably, the well base is provided with a buffer assembly inside.

[0012] Preferably, the buffer assembly includes a buffer pad, the outer side of which is disposed inside the well base, a buffer block is fixedly connected to the bottom end of the buffer pad, a limit block is fixedly connected to the outer side of the buffer block, a second sliding groove is provided inside the well base, and a buffer spring is provided at the bottom end of the buffer block.

[0013] Preferably, the outer side of the limiting block is slidably connected to the inside of the second slide groove, and the bottom end of the buffer spring is disposed inside the well seat.

[0014] This utility model has the following beneficial effects: 1. In this utility model, releasing the handle allows the first spring to push the sliding ring to slide in its natural state, while simultaneously causing the sliding rod to slide through the well seat and finally lock into the locking block. Pulling the handle causes the sliding ring to slide and compress the first spring, while simultaneously causing the sliding rod to disengage from the locking block. This eliminates the need for complex tools such as pry bars and wrenches, significantly shortening the operation time and achieving the effect of adapting to the high-frequency wellhead opening requirements during construction.

[0015] 2. In this utility model, the manhole cover body is placed into the manhole seat, so that the manhole cover body contacts and squeezes the buffer pad. The buffer pad absorbs the impact force through its own deformation. At the same time, the buffer pad drives the buffer block to move downward, so that the limiting block slides along the second sliding groove. Then the buffer block squeezes the buffer spring downward, so that the buffer spring absorbs the impact force through its own elastic deformation, thereby achieving secondary buffering. This avoids hard collision between the two and extends the service life of the manhole cover body and the manhole seat. Attached Figure Description

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Reference Figures 1-3The present invention provides an embodiment of a temporary construction manhole cover that is easy to install and disassemble, comprising a manhole cover body 1, a manhole seat 2 provided on the outside of the manhole cover body 1, a positioning block 3 fixedly connected to the outside of the manhole cover body 1, a positioning groove 4 opened inside the manhole seat 2, the outside of the positioning block 3 being disposed inside the positioning groove 4, a locking block 5 fixedly connected to the outside of the manhole cover body 1, a locking groove 6 opened inside the manhole seat 2, the outside of the locking block 5 being disposed inside the locking groove 6, and a locking component 7 provided on the outside of the manhole seat 2. Specifically, in this embodiment, the manhole cover body 1 is used to cover the manhole opening to prevent people or objects from falling in during construction. The manhole seat 2 is used to cooperate with the manhole opening to provide an installation support base for the manhole cover body 1. The positioning block 3 cooperates with the positioning groove 4. During installation, the positioning block 3 is embedded in the positioning groove 4 to quickly determine the installation position of the manhole cover body 1 on the manhole seat 2 and prevent the manhole cover body 1 from shifting. The locking block 5 cooperates with the locking groove 6. The locking block 5 is inserted into the locking groove 6 to initially limit the position of the manhole cover body 1 and the manhole seat 2, preparing for subsequent locking. The locking component 7 is used to further fix the connection between the manhole cover body 1 and the manhole seat 2 to prevent the manhole cover body 1 from accidentally detaching from the manhole seat 2 during construction.

[0020] Reference Figures 2-4 The locking assembly 7 includes a housing 71, which is fixedly connected to the outside of the well base 2. A first spring 72 is provided inside the housing 71. A sliding ring 73 is provided at one end of the first spring 72. The outside of the sliding ring 73 is slidably connected to the inside of the housing 71. A sliding rod 74 is fixedly connected inside the sliding ring 73. A handle 75 is fixedly connected to the top of the sliding ring 73. The outside of the handle 75 is slidably connected to the inside of the housing 71. The outside of the sliding rod 74 is engaged inside the locking block 5. The outside of the sliding rod 74 is slidably connected to the inside of the well base 2 and the housing 71. Specifically, in this embodiment, the outer shell 71 is used to accommodate and protect the internal components, providing installation and movement space for the first spring 72, the sliding ring 73, etc. The first spring 72 is used to push the sliding ring 73 with elastic force in its natural state, providing power for the locking of the sliding rod 74. The sliding ring 73 is used to drive the sliding rod 74 to move synchronously. The sliding rod 74 slides through the well base 2 and the outer shell 71, and can be locked into the inside of the locking block 5 under the action of the sliding ring 73, restricting the movement of the locking block 5, thereby fixing the position of the well cover body 1 and the well base 2. The handle 75 is used to drive the sliding ring 73 to compress the first spring 72 when pulled, and at the same time, to make the sliding rod 74 disengage from the locking block 5, thereby releasing the locked state and achieving the effect of facilitating the installation or removal of the well cover body 1.

[0021] Example 2: Reference Figure 5 and Figure 6The locking assembly 7 also includes a second spring 76, the exterior of which is disposed inside the well base 2. Drive blocks 77 are provided at both ends of the second spring 76. A buckle 78 is fixedly connected to the top end of the drive block 77, and a slider 79 is fixedly connected to the bottom end of the drive block 77. A first sliding groove 710 is provided inside the well base 2. The exterior of the drive block 77 is slidably connected to the interior of the well base 2, and the exterior of the slider 79 is slidably connected to the interior of the first sliding groove 710. A limiting groove 711 is provided inside the locking block 5, and the exterior of the buckle 78 is engaged with the limiting groove 711 and the interior of the well base 2. Specifically, in this embodiment, the second spring 76 is used to push the drive blocks 77 at both ends by its own elasticity in a natural state, providing power for the locking of the buckle 78. The drive block 77 is used to drive the buckle 78 to move synchronously. The buckle 78 moves with the drive block 77 and can be locked into the limiting groove 711 of the block 5 and the inside of the well base 2, restricting the up and down movement of the block 5, and further reinforcing the connection between the well cover body 1 and the well base 2. The slider 79 slides inside the first sliding groove 710 to limit the movement direction of the drive block 77. The limiting groove 711 is used to accommodate the buckle 78 and provide a locking point for the buckle 78. The buckle 78 helps to limit the block 5, thus eliminating the need for complex tools such as pry bars and wrenches, thereby improving the efficiency of disassembly and assembly.

[0022] Reference Figures 2-4 The manhole cover body 1 has a water inlet 8 inside; Specifically, in this embodiment, the inlet 8 is used to allow water to flow into the well when there is rain or water accumulation on the road surface, so as to prevent water from accumulating on the surface of the well cover body 1.

[0023] Example 3: Reference Figures 7-9 The well base 2 is equipped with a buffer assembly; the buffer assembly includes a buffer pad 9, the outside of which is located inside the well base 2, a buffer block 10 is fixedly connected to the bottom end of the buffer pad 9, a limit block 11 is fixedly connected to the outside of the buffer block 10, a second sliding groove 12 is opened inside the well base 2, a buffer spring 13 is provided at the bottom end of the buffer block 10; the outside of the limit block 11 is slidably connected to the inside of the second sliding groove 12, and the bottom end of the buffer spring 13 is located inside the well base 2; Specifically, in this embodiment, the buffer assembly is used to mitigate the impact force when the manhole cover body 1 contacts the manhole seat 2. The buffer pad 9 is set inside the manhole seat 2 and is in direct contact with the manhole cover body 1. When the manhole cover body 1 is closed or squeezed by external force, the buffer pad 9 first absorbs the impact force through its own deformation. The buffer block 10 is connected to the buffer spring 13. The buffer block 10 will squeeze the buffer spring 13 downward with the deformation of the buffer pad 9. The buffer spring 13 further absorbs the impact force through its own elastic deformation, realizing secondary buffering. The limiting block 11 slides inside the second slide groove 12, which can limit the movement direction of the buffer block 10, prevent the buffer block 10 from deviating and causing buffer failure, and ensure the stable operation of the buffer assembly. The second slide groove 12 inside the manhole seat 2 provides sliding space for the limiting block 11. The limiting block 11 works with the limiting block 11 to guide and limit the buffer block 10, thereby reducing the damage to the manhole cover body 1 and the manhole seat 2 caused by hard collisions.

[0024] Working principle: When the manhole cover body 1 needs to be installed, the manhole cover body 1 is first placed into the manhole seat 2, so that the manhole cover body 1 contacts and squeezes the buffer pad 9. The buffer pad 9 initially absorbs the impact force through its own deformation. At the same time, the buffer pad 9 drives the buffer block 10 to move downward, so that the limiting block 11 slides along the second slide groove 12. Then the buffer block 10 squeezes the buffer spring 13 downward, so that the buffer spring 13 further absorbs the impact force through its own elastic deformation, realizing secondary buffering, thereby avoiding hard collision between the two and extending the service life of the manhole cover body 1 and the manhole seat 2. When it is necessary to fix the manhole cover body 1, first align the manhole cover body 1 with the manhole seat 2, so that the positioning block 3 on the outside of the manhole cover body 1 is embedded in the positioning groove 4 inside the manhole seat 2, and at the same time, let the locking block 5 on the outside of the manhole cover body 1 be inserted into the locking groove 6 inside the manhole seat 2. Then, by releasing the handle 75, the first spring 72 pushes the sliding ring 73 to slide in its natural state, and at the same time drives the sliding rod 74 to slide through the manhole seat 2, and finally be inserted into the locking block 5. Alternatively, by releasing the drive block 77, the second spring 76 can be unfolded and push the drive block 77 to move, and at the same time, the slider 79 slides along the first sliding groove 710, and drives the buckle 78 to be inserted into the limiting groove 711 and the inside of the manhole seat 2. When it is necessary to disassemble the manhole cover body 1, first pull the handle 75. The handle 75 drives the sliding ring 73 to slide and compress the first spring 72. At the same time, the sliding rod 74 disengages from the locking block 5. Alternatively, by pressing the drive block 77, the drive block 77 compresses the second spring 76, causing the buckle 78 to disengage from the limiting groove 711. Finally, lift the manhole cover body 1 upwards, so that the positioning block 3 disengages from the positioning groove 4 and the locking block 5 disengages from the locking groove 6, thus completing the disassembly. This eliminates the need for complex tools such as pry bars and wrenches, greatly shortens the operation time, and achieves the effect of adapting to the high-frequency opening requirements of the manhole during construction.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
