Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a pipeline connection structure for municipal water supply and drainage design. Background Art

[0002] Municipal water supply and drainage is a project that supplies water for living and production to residents and factories, mines, and transportation companies, as well as water for fire fighting and road greening. During the construction of municipal water supply and drainage projects, it is usually necessary to install water pipes. When installing water pipes, the water pipes need to be connected, which is usually achieved with the help of a separate connector component or some complex structures.

[0003] For example, a pipe connection structure disclosed in the patent with announcement number CN219606318U, although the pipe connection structure, through the cross-section of the limiting groove is set to be an isosceles trapezoid, so that the shorter side of the isosceles trapezoid is located at the bottom of the groove, when the flange body is inserted into the pipe from the side, it can guide the limiting protrusion to be inserted into the limiting groove, and the flange body is axially limited, thereby facilitating the assembly of the flange body; however, when the pipe connection structure is actually used, connecting ears are relatively provided at both ends of the neck of the flange body, and a second connecting hole is provided on the connecting ear. When the two flange bodies are spliced ​​with each other, the second connecting holes on the connecting ears can correspond to each other, and the two flange bodies are coaxially connected by bolts passing through the second connecting holes, so that when the pipeline is connected, it is necessary to tighten the bolts multiple times to connect the two flange bodies coaxially to complete the connection of the pipeline; therefore, the operation is relatively cumbersome in the process of connecting the pipeline, so it needs to be improved.

[0028] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0029] The following will be further described in detail with reference to the attached Figures 1-6 This embodiment will be further described in detail.

[0030] Combined with Figures 1-6As shown in the figure, a pipeline connection structure for municipal water supply and drainage design in this embodiment includes an upper half-ring 220 and a lower half-ring 230 that are spliced with each other. Ring-shaped blocks 210 are provided at both ends of the upper half-ring 220 and the lower half-ring 230 for splicing. Upper connecting blocks 130 and lower connecting blocks 140 are provided on both sides of the upper half-ring 220 and the lower half-ring 230. A locking component is provided on the upper connecting block 130 for fixing the upper connecting block 130 on the corresponding lower connecting block 140. The locking component includes a fixed cylinder 150. A liftable locking rod 250 is provided inside the fixed cylinder 150. The lower end of the locking rod 250 penetrates through the upper connecting block 130. A locking block 410 is provided at the penetrating end of the locking rod 250. A cavity 620 is provided inside the lower connecting block 140. An opening 610 for the locking rod 250 and the locking block 410 to extend into the cavity 620 is provided on the side wall of the lower connecting block 140 corresponding to the upper connecting block 130. The locking rod 250 drives the locking block 410 to rotate so that the locking block 410 is misaligned with the opening 610, realizing the fixation between the upper connecting block 130 and the lower connecting block 140.

[0031] The pipeline connection structure in this embodiment is used for docking between pipelines. In actual use, the ring-shaped block 210 is welded and connected inside the corresponding upper half-ring 220 and lower half-ring 230. When the upper half-ring 220 and the lower half-ring 230 are spliced with each other, a connecting cylinder that hugs the outside of the first pipeline 100 and the second pipeline 110 is formed. At this time, the opposite ring-shaped blocks 210 are also spliced to form a circular connecting ring. Among them, annular grooves 240 are provided on the outer side walls of both the first pipeline 100 and the second pipeline 110. The connecting ring is snapped into the annular groove 240 on the first pipeline 100 or the second pipeline 110, enabling the connecting cylinder to fixedly connect the first pipeline 100 and the second pipeline 110, that is, realizing the mutual connection between the first pipeline 100 and the second pipeline 110.

[0032] It should be noted that when the connecting cylinder docks the first pipeline 100 and the second pipeline 110, the diameters of the first pipeline 100 and the second pipeline 110 are the same, and the opposite ends are tightly abutted against each other.

[0033] In actual use, when the upper half-ring 220 and the lower half-ring 230 are spliced together, the locking rod 250 and the locking block 410 can pass through the notch 610 and extend into the cavity 620 and rotate, so that the locking block 410 can be misaligned with the notch 610, enabling the locking block 410 to abut against the upper side wall of the cavity 620. Furthermore, the locking assembly can lock the upper connecting block 130 and the lower connecting block 140, so that the two mutually spliced upper half-ring 220 and lower half-ring 230 can be fixed, thereby enabling the connecting assembly to connect the first pipe 100 and the second pipe 110. Compared with the existing method of connecting by screwing multiple bolts, in this embodiment, the first pipe 100 and the second pipe 110 are connected by rotating the locking rod 250, without the need to screw the bolts multiple times, making the operation simple and convenient for actual use.

[0034] Wherein, in order to improve the sealing performance of the pipe connection structure when connecting the first pipe 100 and the second pipe 110, sealing gaskets are provided in both the upper half-ring 220 and the lower half-ring 230 at the abutting positions of the first pipe 100 and the second pipe 110. Through the setting of the sealing gaskets, it can seal between the first pipe 100 and the second pipe 110 to prevent water leakage.

[0035] Combined Figures 3-6 As shown, in this embodiment, an installation cavity with an opening facing the upper connecting block 130 is provided in the fixed cylinder 150. Vertical grooves 320 are oppositely provided on the side wall of the installation cavity along its height direction, and a horizontal groove 330 is provided at the bottom end of the vertical groove 320; a fixed column 420 of the locking rod 250 is located in the installation cavity, and a sliding column 340 that extends into the corresponding vertical groove 320 and slides is provided outside the fixed column 420.

[0036] In actual use of this embodiment, as Figure 6 shown, the upper connecting block 130 is provided with a through hole 600 for the locking rod 250 to pass through. The fixed cylinder 150 is connected to the upper side wall of the upper connecting block 130 by welding. When the upper half-ring 220 and the lower half-ring 230 are spliced together, the upper connecting block 130 and the corresponding lower connecting block 140 can be mutually attached, so that the through hole 600 and the notch 610 can be aligned with each other. Among them, the locking rod 250 passes through the fixed cylinder 150 and extends out. By the locking rod 250, the sliding column 340 moves down along the vertical groove 320, driving the locking block 410 to pass through the notch 610 and extend into the cavity 620. At this time, the locking rod 250 is rotated, so that the locking rod 250 can drive the fixed column 420 to drive the sliding column 340 to slide into the horizontal groove 330, and further enable the locking rod 250 to drive the locking block 410 to rotate in the cavity 620, causing the locking block 410 to be misaligned with the notch 610, so that the upper end surface of the locking block 410 can abut against the upper side wall of the cavity 620, thereby enabling the two mutually spliced upper half-ring 220 and lower half-ring 230 to be fixed;

[0037] During actual use, the upper and lower side walls of the lock block 410 are adapted to the upper and lower side walls of the cavity 620, so that when the lock block 410 extends into the cavity 620 and rotates, the lock block 410 can be stably located in the cavity 620, thereby enabling the upper connecting block 130 and the lower connecting block 140 to fit closely together, and thus making the fixing effect between the upper half ring 220 and the lower half ring 230 better;

[0038] Among them, the configurations of the lock rod 250 and the lock block 410 correspond to the shape of the notch 610, so that when the lock rod 250 drives the lock block 410 to move downward along the through hole 600, the lock block 410 can pass through the notch 610 and extend into the cavity 620. At this time, rotating the lock rod 250 enables the lock block 410 to be misaligned with the notch 610, realizing the fixation between the upper connecting block 130 and the lower connecting block 140;

[0039] Among them, when the sliding column 340 slides to the end of the horizontal groove 330 far from the vertical groove 320, the lock block 410 can be completely misaligned with the notch 610. When the sliding column 340 slides and abuts against the side wall at the other end of the horizontal groove 330, at this time, the lock rod 250 and the lock block 410 are aligned with the notch 610, so that the lock block 410 can be taken out from the lower connecting block 140, thereby releasing the fixation between the upper connecting block 130 and the lower connecting block 140.

[0040] Combined with Figures 4-5 As shown in the figure, in this embodiment, a spring 500 for driving the fixing column 420 to move upward is sleeved on the lock rod 250 in the installation cavity.

[0041] When this embodiment is actually used, the lower end of the vertical groove 320 is connected to one end of the horizontal groove 330, so that pressing the lock rod 250 downward enables the lock rod 250 to drive the fixing column 420 to move downward along the fixing cylinder 150. Further, the fixing column 420 moves downward, compressing the spring 500, enabling the sliding column 340 to slide downward along the vertical groove 320. When the sliding column 340 slides downward to the bottom wall of the vertical groove 320, at this time, the lock rod 250 drives the lock block 410 to extend into the cavity 620, and rotating the lock rod 250 enables the lock rod 250 to drive the lock block 410 to rotate in the cavity 620 and be misaligned with the notch 610;

[0042] Among them, due to the arrangement of the spring 500, when the sliding column 340 slides from the horizontal groove 330 to the bottom wall of the vertical groove 320, the spring 500 can push the fixing column 420 upward, enabling the sliding column 340 to move upward along the vertical groove 320. Further, the fixing column 420 can drive the lock rod 250 to drive the lock block 410 to retract into the through hole 600, thereby releasing the fixation between the upper connecting block 130 and the lower connecting block 140;

[0043] Among them, when the spring 500 pushes the fixed column 420 to drive the lock rod 250 to move upward, and can drive the lock block 410 to retract into the through hole 600, the upper connecting block 130 can be placed flat on the ground, avoiding damage to the lock rod 250 and the lock block 410;

[0044] Among them, through the setting of the vertical groove 320, the vertical groove 320 can align the through hole 600 and the notch 610, so as to facilitate the lifting of the lock block 410 driven by the lock rod 250 between the cavity 620 and the through hole 600;

[0045] One end of the lock rod 250 extending out of the fixed cylinder 150 is provided with a hand crank 160. Through the setting of the hand crank 160, it is convenient for the operator to press and rotate the lock rod 250, facilitating operation;

[0046] In actual use of this embodiment, in order to avoid the accidental rotation of the hand crank 160 by the operator when the sliding column 340 is in the horizontal groove 330, resulting in the accidental release of the fixation between the upper connecting block 130 and the lower connecting block 140, a limiting groove 400 is provided along the axial direction on the side wall of the lock rod 250 extending out of the fixed cylinder 150, and a limiting member for locking the rotation of the lock rod 250 is provided at the upper end surface of the fixed cylinder 150;

[0047] Among them, the limiting member includes mounting plates 300 oppositely arranged on the upper end surface of the fixed cylinder 150. A rotating plate 310 is rotatably arranged between the opposite mounting plates 300 through a hinge rod. When the lock rod 250 is pressed and rotated, when the sliding column 340 slides into the horizontal groove 330, that is, the limiting groove 400 rotates to align with the rotating plate 310. At this time, the rotating plate 310 is toggled, so that one end of the rotating plate 310 rotates into the limiting groove 400, thereby limiting the lock rod 250 and preventing the lock rod 250 from rotating circumferentially, thus preferably avoiding the accidental rotation of the hand crank 160 by the operator.

[0048] Working principle: When connecting the first pipeline 100 and the second pipeline 110, first splice the upper half ring 220 and the lower half ring 230 to form a connecting cylinder that hugs the first pipeline 100 and the second pipeline 110. At this time, the opposite annular blocks 210 are also spliced to form a circular connecting ring, which is snapped into the annular groove 240 on the corresponding first pipeline 100 or the second pipeline 110. Then, by pressing and rotating the hand crank 160, the sliding column 340 moves downward along the vertical groove 320, so that the lock rod 250 drives the lock block 410 to extend into the cavity 620 through the notch 610, and the lock rod 250 is rotated, so that the lock rod 250 can drive the sliding column 340 to slide into the horizontal groove 330, and further the lock rod 250 can drive the lock block 410 to rotate in the cavity 620, causing a dislocation between the lock block 410 and the notch 610, so that the two spliced upper half ring 220 and lower half ring 230 can be fixed.

[0049] In summary, the above are only the preferred embodiments of the present utility model. All equivalent changes and modifications made within the scope of the patent application for the present utility model shall fall within the scope covered by the patent of the present utility model.
