Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of communication manholes, in particular to a height-adjustable docking manhole neck. Background Art
[0002] When installing a prefabricated communication manhole, you need to dig a pit underground and then bury the box in the pit. Then the box is connected to the ground through the manhole neck. Some boxes are buried deeper and the manhole neck that needs to be installed is also longer. The existing prefabricated manhole necks are generally made of one-piece clinker injection molding. The longer the manhole neck, the larger the specifications of the injection molding machine required, resulting in higher processing costs. The longer the manhole neck, the easier it is to be compressed and deformed. The longer the manhole neck, the heavier the mass and the more difficult it is to install. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a height-adjustable docking well neck, which solves the problems raised in the above-mentioned background technology.
[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a height-adjustable docking well neck, including a well neck main body, the inner wall of the lower end of the well neck main body is provided with a bottom connecting inner ring, a sealing insert ring is provided below the bottom connecting inner ring, a top sleeve outer ring groove is provided on the outer side above the well neck main body, a top connecting inner ring is provided inside the upper end of the well neck main body, a sealing groove is provided above the top connecting inner ring, and a support plate is provided between the bottom of the top connecting inner ring and the inner wall of the well neck main body.
[0005] Preferably, the well neck is integrally injection-molded from plastic, has a relatively small height, and well necks of different heights are formed by connecting each other up and down.
[0006] Preferably, through holes are opened around the bottom connecting inner ring, and screw holes corresponding to the positions of the through holes are opened above the top connecting inner ring. The two well necks can be fixedly connected by passing the screws through the through holes and screwing them into the screw holes.
[0007] Preferably, the sealing insert ring is inserted into the sealing groove, and a sealant is provided inside the sealing groove, and the sealant seals the matching gap between the sealing insert ring and the sealing groove.
[0008] Preferably, the bottom of the well neck body is sleeved on the outside of the top sleeve outer ring groove with clearance fit, and the lower end surface of the well neck body does not contact the bottom surface of the top sleeve outer ring groove but is as close as possible.
[0009] Preferably, after the two well necks are spliced up and down, the bottom connecting inner ring and the top connecting inner ring are connected to strengthen the inside of the well neck, thereby greatly improving the compressive strength of the well neck.
[0010] The utility model provides a height-adjustable docking well neck, which has the following beneficial effects:
[0011] 1. The height-adjustable docking well neck has the effect of reducing processing costs through the coordinated arrangement of the well neck main body, the bottom connecting inner ring and the top connecting inner ring. By respectively arranging the top connecting inner ring and the bottom connecting inner ring that can be connected by screws at the upper and lower ends of the well neck main body, a high-sized well neck can be obtained by splicing. Therefore, it is not necessary to invest in a large injection molding machine to produce a well neck of a suitable size, thereby reducing processing costs.
[0012] 2. The height-adjustable docking well neck has the effect of high strength and not easily deformed by compression through the coordinated arrangement of the bottom connecting inner ring and the top connecting inner ring. The high-sized well neck obtained by splicing forms reinforcement ribs evenly distributed up and down inside, which are formed by connecting the bottom connecting inner ring and the top connecting inner ring. Therefore, even if the height of the well neck is very large, its strength is also very high and it is not easily deformed by compression.
[0013] 3. The height-adjustable docking well neck has the effect of being easy to install through the coordinated arrangement of the well neck main body, the bottom connecting inner ring and the top connecting inner ring. By respectively arranging the top connecting inner ring and the bottom connecting inner ring which can be connected by screws at the upper and lower ends of the well neck main body, it is possible to split a well neck with a large height into several parts. The split well neck has a small volume and light weight, thereby reducing the intensity of the installation work and achieving the effect of easy installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] See also Figure 1The utility model provides a technical solution: a height-adjustable docking well neck, which is made of plastic integral injection molding, and its height dimension is small. Each well neck is connected up and down to form well necks of different heights. The more the number of connections, the higher the height of the well neck. It includes a well neck main body 1, and the inner wall of the lower end of the well neck main body 1 is provided with a bottom connecting inner ring 2, and a sealing insert ring 3 is provided below the bottom connecting inner ring 2. A top sleeve outer ring groove 4 is provided on the outer side above the well neck main body 1, and the bottom of the well neck main body 1 is sleeved on the outer side of the top sleeve outer ring groove 4 and is clearance-matched. The lower end surface of the well neck main body 1 does not contact the bottom surface of the top sleeve outer ring groove 4 but is as close as possible. A top connecting inner ring 5 is provided inside the upper end of the well neck main body 1, and the bottom A through hole 8 is provided around the connecting inner ring 2, and a screw hole 9 corresponding to the position of the through hole 8 is provided above the top connecting inner ring 5. The screws pass through the through holes 8 and are screwed into the screw holes 9 to fix the two well necks in connection. A sealing groove 6 is provided above the top connecting inner ring 5, and the sealing insert ring 3 is inserted into the sealing groove 6. A sealant 10 is provided inside the sealing groove 6. The sealant 10 seals the matching gap between the sealing insert ring 3 and the sealing groove 6. A support plate 7 is provided between the bottom of the top connecting inner ring 5 and the inner wall of the well neck body 1. The support plate 7 can increase the strength of the top connecting inner ring 5. After the two well necks are spliced up and down, the bottom connecting inner ring 2 is connected to the top connecting inner ring 5, which plays a reinforcing role inside the well neck, thereby greatly improving the compressive strength of the well neck.
[0018] When in use, first prefabricate such well necks of different heights in the factory, and require that the top connecting inner ring 5 and the bottom connecting inner ring 2 at the upper and lower ends of all well neck main bodies 1 have the same structural dimensions, so that well necks of various sizes can be connected up and down, and further according to the height of the well neck required by the communication personnel well, well necks of appropriate sizes are selected for splicing. For example, if the height of the well neck required by the communication personnel well is 1.9 meters, four 40-centimeter well necks and one 30-centimeter well neck are selected for splicing. After selecting the splicing scheme, each well neck is transported to the site and then buried while connected by screws. At this time, since each well neck is small in size and weight, transportation and installation are relatively labor-saving, thereby achieving the effect of easy installation. A number of reinforcing ribs formed by connecting the bottom connecting inner ring 2 and the top connecting inner ring 5 are arranged inside the spliced well neck, so that the strength of the well neck is improved, and the splicing is sealed by sealant 10. Since the well neck after separation is small in size, the required injection molding machine specifications are also small, thereby reducing the manufacturing cost.
[0019] To sum up, the height-adjustable docking well neck realizes that a high-sized well neck can be obtained by splicing by respectively arranging a top connecting inner ring 5 and a bottom connecting inner ring 2 which can be connected by screws at the upper and lower ends of the well neck main body 1. Therefore, it is not necessary to invest in a large injection molding machine to produce a well neck of suitable size, thereby reducing the processing cost. The high-sized well neck obtained by splicing forms reinforcing ribs evenly distributed up and down inside, which are formed by connecting the bottom connecting inner ring 2 and the top connecting inner ring 5. Therefore, even if the height dimension of the well neck is large, its strength is also high and it is not easily deformed by compression, so that a well neck with a large height dimension can be split into several parts. The split well neck is small in size and light in weight, thereby reducing the intensity of the installation work and achieving the effect of facilitating installation.
[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
