Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an anti-settling drainage expansion joint pipe fitting. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they serve as drainage pipes, they should be collectively referred to as drainage pipes. Drainage fittings generally refer to nodes in water supply and drainage, which refers to the branching points of pipelines or the joints of intersection drainage pipes, and are mainly used for connection between two water pipes.

[0003] After the drainage pipe fittings in the prior art are connected to the drainage pipe, long-term use will cause the pipe to sink. The main reason is that the water flow is large, and the support effect of the drainage pipe fittings themselves is poor. The impact force will cause damage to the pipe. To this end, we provide an anti-settling drainage expansion joint pipe fitting to solve the problem. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0037] Embodiment 1:

[0038] An anti-settling drainage expansion joint pipe fitting comprises a corrugated section 1 and two connecting sections 2, one end of the two connecting sections 2 is fixedly connected to the two ends of the corrugated section 1 respectively, and a supporting mechanism is provided at the bottom of the connecting section 2 to support the pipe fitting;

[0039] One implementation of the first embodiment is as follows: the support mechanism includes an arc-shaped support plate 3 fixedly arranged at the bottom of the connecting section 2, a base 4 is arranged at the bottom of the arc-shaped support plate 3, a sleeve 24 is fixedly connected to the top of the base 4, and a support rod 5 for supporting the arc-shaped support plate 3 is inserted into the sleeve 24;

[0040] The buffer mechanism is fixedly arranged on the arc-shaped support plate 3 and can play a buffering role for the drainage pipe fittings.

[0041] In this embodiment, it is considered that after the drainage pipe fittings are connected to the drainage pipe, long-term use may cause the pipe to sink. The main reason is that the water flow is large, and the supporting effect of the drainage pipe fittings themselves is poor. The impact force may cause damage to the pipe. Therefore, by setting a supporting mechanism, an arc-shaped supporting plate 3 can be provided at the two connecting sections 2 of the drainage pipe fittings. By making the base 4 contact the ground, the sleeve 24, the supporting rod 5 and the arc-shaped supporting plate 3 have a supporting force, which can support the two connecting sections 2, thereby improving the stability of the drainage pipe fittings and avoiding the occurrence of the drainage pipe fittings sinking due to the large water flow and impact.

[0042] It solves the problem that after the drainage pipe fittings are connected to the drainage pipe, long-term use will cause the pipe to sink. The main reason is that the water flow is large, and the support effect of the drainage pipe fittings themselves is poor, and the impact force will cause damage to the pipe.

[0043] It should be noted that the material of the corrugated section 1 is elastic material. When the drainage pipe is expanded or contracted due to external force or temperature changes, the elastic material can effectively absorb and alleviate these changes, maintaining the stability of the pipeline system. At the same time, the expansion and contraction function of the drainage pipe fittings can also prevent water leakage caused by pipeline settlement.

[0044] Embodiment 2:

[0045] On the basis of the first embodiment, the support mechanism in this embodiment can support the drainage pipe fittings to prevent the drainage pipe fittings from sinking. However, the drainage pipe fittings are only rigidly supported by the support mechanism, and are still easily damaged and sink under the impact of water flow. The buffer mechanism in this application includes a buffer groove 6 opened inside the support rod 5, and the inner wall of the buffer groove 6 is slidably connected with a buffer block 7, and the top of the buffer block 7 is fixedly connected with a buffer rod 8, and the top of the buffer rod 8 penetrates to the top of the buffer rod 8 and is fixedly connected to the bottom of the arc-shaped support plate 3;

[0046] The bottom of the buffer block 7 is fixedly connected to a piston 9 , the bottom of the piston 9 is fixedly connected to a buffer spring 10 , and the bottom of the buffer spring 10 is fixedly connected to the inner wall of the buffer groove 6 .

[0047] In this embodiment, it is considered that the drainage pipe fittings are only rigidly supported by the supporting mechanism, and are still easily damaged and subsided under the impact of water flow. Therefore, by setting a buffer mechanism, when the water flow passes through the connecting section 2 and generates an impact force, the impact force will be transmitted to the arc-shaped support plate 3, and then transmitted from the arc-shaped support plate 3 to the buffer rod 8, the buffer block 7 and the piston 9. The piston 9 will sink in the buffer groove 6 under the impact force. The inside of the buffer groove 6 is a closed cavity under the action of the piston 9. The gas will be compressed when the piston 9 sinks, which plays a certain buffering role. At the same time, the spring at the bottom of the piston 9 can also reduce part of the impact force to achieve a buffering effect.

[0048] The invention solves the problem that the drainage pipe fittings are easily damaged and sink under the impact of water flow because they are rigidly supported only by the supporting mechanism.

[0049] Preferably, the piston 9 is made of rubber, and its outer surface is in close contact with the inner wall of the buffer groove 6 .

[0050] In this embodiment, by providing the piston 9, a closed cavity can be formed inside the buffer groove 6. When the piston 9 sinks, the gas will be compressed, which plays a certain buffering role.

[0051] Embodiment three:

[0052] On the basis of the first embodiment, the support mechanism of this embodiment can support the drainage pipe fittings to prevent the drainage pipe fittings from sinking. However, considering the different terrains, if the base 4 in the support mechanism cannot be squeezed out of the ground, the support effect will not be achieved. In this application, an adjustment mechanism is provided inside the sleeve 24, which can adjust the position of the base 4 according to the terrain.

[0053] The adjustment mechanism includes a shell 11 fixedly arranged at the bottom of the support rod 5, a linkage block 12 is arranged inside the shell 11, a driving rod 13 is fixedly connected to one side of the linkage block 12, one end of the driving rod 13 passes through the outside of the sleeve 24, a connecting rod 14 is movably connected to the top of the linkage block 12 through a rotating shaft, one end of the connecting rod 14 is movably connected to a connecting block 15 through a rotating shaft, a moving block 16 is fixedly connected to one side of the connecting block 15, a pin rod 17 is fixedly connected to one side of the moving block 16, one end of the pin rod 17 passes through the outside of the shell 11, and a plurality of pin holes 18 for use with the pin rod 17 are provided on both sides of the sleeve 24.

[0054] In this embodiment, the different terrains are taken into consideration. If the base 4 in the support mechanism cannot be squeezed out from the ground, there will be no support effect. Therefore, by setting an adjustment mechanism, the linkage block 12 can be driven to move by pressing the driving rod 13. The linkage block 12 will drive the connecting rod 14 to make appropriate rotations around the two rotating shafts, and at the same time drive the connecting block 15, the moving block 16 and the pin rod 17 to move along the trajectory of the sliding groove 21 and the sliding block 20, so that the pin rod 17 leaves the inside of the pin hole 18, and then the position of the sleeve 24 and the base 4 can be adjusted to the appropriate position, and then the driving rod 13 is released, and the elastic force generated by the reset spring 19 pushes the linkage block 12 and resets, and at the same time, the above steps are reversed, so that the pin rod 17 enters the corresponding pin hole 18 to complete the fixation of the position of the base 4. At this time, the base 4 is in contact with the ground, which improves the stability of the support;

[0055] The problem that the supporting effect cannot be achieved if the base 4 in the supporting mechanism cannot be squeezed out from the ground due to the different terrains is solved.

[0056] Preferably, a return spring 19 is fixedly connected to one side of the linkage block 12 , and one end of the return spring 19 is fixedly connected to the inner wall of the housing 11 .

[0057] In this embodiment, a reset spring 19 is provided so that after the driving rod 13 is released, the elastic force generated by the reset spring 19 can push the linkage block 12, the connecting rod 14, the connecting block 15, the moving block 16 and the pin rod 17 to move, thereby achieving a reset effect.

[0058] Preferably, sliding blocks 20 are fixedly connected to both sides of the moving block 16 , and a sliding groove 21 for use with the sliding block 20 is formed on the inner wall of the housing 11 .

[0059] In this embodiment, the sliding block 20 and the sliding groove 21 are provided to limit the moving track of the moving block 16 . When the connecting rod 14 pries the moving block 16 to move, the moving block 16 can only move along the track of the sliding block 20 and the sliding groove 21 .

[0060] Preferably, a limiting block 22 is fixedly connected to one side of the housing 11 , and a limiting groove 23 used in conjunction with the limiting block 22 is formed on the inner wall of the sleeve 24 .

[0061] In this embodiment, by providing the limit block 22 and the limit groove 23 , a limiting effect can be played when the position of the sleeve 24 and the base 4 is adjusted, so that they can only be adjusted and moved along the track of the limit block 22 and the limit groove 23 .

[0062] Working principle: By arranging arc-shaped support plates 3 at the two connecting sections 2 of the drainage pipe fittings, and making the base 4 contact the ground, the sleeve 24, the support rod 5 and the arc-shaped support plate 3 have a supporting force, which can support the two connecting sections 2, thereby improving the stability of the drainage pipe fittings and avoiding the occurrence of the drainage pipe fittings sinking due to the impact of large water flow;

[0063] At the same time, when the water flows through the connecting section 2 and generates an impact force, the impact force will be transmitted to the arc support plate 3, and then transmitted to the buffer rod 8, the buffer block 7 and the piston 9 by the arc support plate 3. The piston 9 will sink in the buffer groove 6 under the action of the piston 9. The inside of the buffer groove 6 is a closed cavity under the action of the piston 9. The gas will be compressed when the piston 9 sinks, which plays a certain buffering role. At the same time, the spring at the bottom of the piston 9 can also reduce part of the impact force to achieve a buffering effect;

[0064] And taking into account the different terrains, if the base 4 in the supporting mechanism cannot be squeezed out from the ground, there will be no supporting effect. Therefore, by setting up an adjustment mechanism, the linkage block 12 can be driven to move by pressing the driving rod 13. The linkage block 12 will drive the connecting rod 14 to make appropriate rotations around the two rotating shafts, and at the same time drive the connecting block 15, the moving block 16 and the pin rod 17 to move along the trajectory of the sliding groove 21 and the sliding block 20, so that the pin rod 17 leaves the inside of the pin hole 18, and then the position of the sleeve 24 and the base 4 can be adjusted to the appropriate position, and then the driving rod 13 is released, and the elastic force generated by the reset spring 19 pushes the linkage block 12 and resets, and at the same time the above steps are reversed, so that the pin rod 17 enters the corresponding pin hole 18 to complete the fixation of the position of the base 4. At this time, the base 4 is in contact with the ground, which improves the stability of the support.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
