Abstract
Description
Technical Field
[0001] The utility model relates to the field of connection mechanisms, and specifically to a municipal pipeline connection mechanism. Background Art
[0002] The pipeline connection process is one of the key technologies in engineering construction. It refers to precisely docking prefabricated pipe segments according to the specific requirements of the design drawings to build a complete and efficiently operating pipeline system. This process needs to comprehensively consider the pipe material properties and its actual application environment. However, when using traditional connection methods, leakage or unstable connection is inevitable after connection. In order to ensure the safety, stability, and functional performance of the storage and transportation system, a municipal pipeline connection mechanism needs to be designed to solve the existing problems.
[0003] An existing municipal pipeline connection mechanism usually uses prefabricated steel pipes with grooves at both ends. During installation, a rubber ring is sleeved on one prefabricated steel pipe. Then, after the two prefabricated steel pipes are spliced, the rubber ring is moved to the splicing position of the two prefabricated steel pipes. Then, two sets of fixing components are sleeved at the splicing position, and the rubber ring is squeezed by the fixing components to make the splicing position in a sealed state, so as to fix and seal the splicing of the two prefabricated steel pipes.
[0004] However, for an existing municipal pipeline connection mechanism, in order to improve the waterproof effect of the rubber ring, the sleeved rubber ring needs to closely adhere to the surface of the prefabricated steel pipe. However, the rubber ring closely adhering to the surface of the prefabricated steel pipe is inconvenient to operate during movement, affecting the laying efficiency of the pipeline. Summary of the Utility Model

[0013] By adopting the above technical solution, by fixedly installing the second rubber ring inside the first clamp, the use of rubber rings during the installation process is avoided, effectively improving the pipeline laying efficiency.

[0014] The present utility model is further configured such that inner grooves are formed inside the first rubber ring and the second rubber ring, and the width of the inner grooves is the same as the width of the two limiting blocks.

Since two groups of extrusion blocks are arranged on both sides of the inner ring of the second clamp, the extrusion blocks will extrude both ends of the second rubber ring against both ends of the first rubber ring, preventing leakage at the joint of the two groups of steel pipes, thereby achieving the effect of enhancing the sealing performance of the connecting mechanism.

[0032] Embodiment 1
[0033] A municipal pipeline connecting mechanism, as Figure 1 - Figure 5As shown in the figure, it includes a steel pipe 1. Grooves 2 are provided at both ends of the steel pipe 1.

The provision of the through holes 62 is conducive to the rapid fixation between the first clamp 4 and the second clamp 5.

[0035] Please refer to Figure 2 , the first rubber ring 3 is fixedly installed inside the second clamp 5. The two ends of the first rubber ring 3 extend outwards to the limiting bases on both sides of the second clamp 5. One side of the two ends of the first rubber ring 3 is provided with an inclined angle. By fixedly installing the first rubber ring 3 inside the second clamp 5, the use of rubber rings during the installation process can be avoided, and the laying efficiency of the pipeline can be effectively improved.

[0037] Please refer to Figure 2 and Figure 4, inner grooves are provided inside the first rubber ring 3 and the second rubber ring 31, and the width of the inner grooves is the same as the width of the two groups of limit blocks 21. By setting the width of the inner grooves provided inside the first rubber ring 3 and the second rubber ring 31 to be the same as the width of the two groups of limit blocks 21, it is convenient for the first clamp 4 and the second clamp 5 to fix the two groups of steel pipes 1.
[0038] Please refer to Figure 2 and Figure 4 , the first rubber ring 3 and the second rubber ring 31 are made of waterproof rubber, and the material is relatively soft. By setting the materials of the first rubber ring 3 and the second rubber ring 31 as waterproof rubber, it is convenient for the first clamp 4 and the second clamp 5 to squeeze the first rubber ring 3 and the second rubber ring 31, so as to achieve a sealing effect.
[0039] Please refer to Figure 2 and Figure 4 , the diameters of the inner rings of the first rubber ring 3 and the second rubber ring 31 are the same as the diameter of the groove 2, and the diameters of the inner grooves provided in the inner rings of the first rubber ring 3 and the second rubber ring 31 are the same as the diameter of the limit block 21.

[0040] Embodiment 2
[0041] A municipal pipeline connection mechanism, as Figure 6 shown, the technical solutions and parts of this embodiment are basically the same as those of Embodiment 1, and the same technical parts will not be elaborated here. The difference lies in that: a rubber pad 7 is placed on one side of the steel pipe 1, and the diameter of the rubber pad 7 is the same as the diameter of the steel pipe 1.
[0042] After splicing the two groups of steel pipes 1, the two groups of steel pipes 1 will have a clamping effect on the rubber pad 7. Since the thickness of the rubber pad 7 is designed to be relatively thin, it can be sleeved into the inner grooves of the first rubber ring 3 and the second rubber ring 31 together with the limit blocks 21 at both ends of the two groups of steel pipes 1, without affecting the installation of the first clamp 4 and the second clamp 5. After fixing the two groups of steel pipes 1 through the first clamp 4 and the second clamp 5, the rubber pad 7 between the two groups of steel pipes 1 will play a role in preventing leakage, thereby enhancing the sealing performance of the connection mechanism.
[0043] The working principle of the present utility model is as follows: After aligning and splicing two groups of steel pipes 1, a first clamp 4 and a second clamp 5 are sleeved at the splicing position. Then, bolts 6 are sleeved in the through holes 62 of the limit bases fixedly installed on both sides of the first clamp 4 and the second clamp 5, and are matched with nuts 61 to fix the first clamp 4 and the second clamp 5. Since the first rubber ring 3 and the second rubber ring 31 are installed inside the first clamp 4 and the second clamp 5, and the first clamp 4 and the second clamp 5 will squeeze the first rubber ring 3 and the second rubber ring 31 during the fixing process, making the first rubber ring 3 and the second rubber ring 31 closely adhere to the steel pipe 1, thereby achieving a sealing effect. Moreover, two groups of extrusion blocks 51 are provided on both sides of the inner ring of the second clamp 5. When the first clamp 4 and the second clamp 5 are sleeved on the preset grooves 2 of the two groups of steel pipes 1 and fixed, the two ends of the second rubber ring 31 on the inner ring of the first clamp 4 will be inserted between the first rubber ring 3 and the second clamp 5 through the inclined angles opened at both ends of the first rubber ring 3. Since two groups of extrusion blocks 51 are provided on both sides of the inner ring of the second clamp 5, the extrusion blocks 51 will cause the two ends of the second rubber ring 31 to squeeze the two ends of the first rubber ring 3, making the adhesion between the first rubber ring 3 and the second rubber ring 31 and the splicing position of the steel pipe 1 closer, and avoiding leakage.
[0044] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
