Description

Technical Field

[0001] The utility model belongs to the technical field of reinforced concrete pipes, in particular to a reinforced concrete pipe which is easy to splice. Background Art

[0002] Reinforced concrete pipes are often used in municipal water conservancy. One end of the pipe is provided with a splicing structure whose inner diameter is larger than the outer diameter of the other end. When splicing two reinforced concrete pipes together, a sealing ring needs to be installed on the surface of the smaller end, and then the section needs to be inserted into the larger end of the other reinforced concrete pipe. The sealing of the connection between the two reinforced concrete pipes is achieved through the sealing ring. However, the inner surface of the reinforced concrete pipe is mostly rough. During the plug-in process, the outer and inner sides of the sealing ring rub against the inner and outer walls of the two reinforced concrete pipes respectively, which can easily cause damage to the sealing ring, thereby affecting the sealing effect of the sealing ring.

[0003] In summary, the utility model provides a reinforced concrete pipe that is easy to splice to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a reinforced concrete pipe that is easy to splice, which is achieved by the following specific technical means:

[0005] A reinforced concrete pipe that is easy to splice, comprising a reinforced concrete pipe, one end of the reinforced concrete pipe is provided with a connecting cover, the surface of the other end of the reinforced concrete pipe is arrayed with a plurality of movable grooves, the surface of the other end of the reinforced concrete pipe is also covered with a movable ring, the inner side of the movable ring is arrayed with a plurality of movable blocks at one end close to the connecting cover, and the plurality of movable blocks are respectively inserted into the plurality of movable grooves, a limiting ring is provided on the surface of the reinforced concrete pipe at a position close to the movable groove, a sealing ring is fixedly installed on one side of the limiting ring close to the movable ring, a sealing ring is provided at one end of the sealing ring close to the movable ring, and the sealing ring is fixedly connected to the movable ring.

[0006] Furthermore, the inner dimension of the movable ring is larger than the outer dimension of the movable ring.

[0007] Furthermore, the outer dimension of the limiting ring is equal to the outer dimension of the connecting cover.

[0008] Furthermore, the distance from the limiting ring to the end surface of the reinforced concrete pipe at one end where the movable groove is provided is equal to the width of the connecting cover.

[0009] Furthermore, the sum of the widths of the sealing ring and the movable ring is greater than the width of the connecting cover.

[0010] Furthermore, a spring is installed inside the movable groove between the limiting ring and the movable block, and two ends of the spring are respectively against the inner wall of the movable ring and the movable groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a sealing ring that can expand outwards. When two reinforced concrete pipes are spliced, the sealing ring expands from the inside to the outside, which can effectively reduce the friction between the sealing ring and the inner wall and the outer wall of the reinforced concrete pipe, thereby reducing the probability of damage to the sealing ring and improving the sealing performance of the connection between the two reinforced concrete pipes.

[0018] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0019] like Figure 1-3 As shown, the utility model provides a reinforced concrete pipe that is easy to splice, including a reinforced concrete pipe 1, a connecting cover 2 is provided at one end of the reinforced concrete pipe 1, a plurality of movable grooves 3 are arranged in an array on the surface of the other end of the reinforced concrete pipe 1, a movable ring 4 is also mounted on the surface of the other end of the reinforced concrete pipe 1, a plurality of movable blocks 5 are arranged in an array on the inner side of the movable ring 4 near the end of the connecting cover 2, and the plurality of movable blocks 5 are respectively inserted into the plurality of movable grooves 3, a limiting ring 6 is provided on the surface of the reinforced concrete pipe 1 at a position near the movable groove 3, a sealing ring 7 is fixedly installed on one side of the limiting ring 6 near the movable ring 4, a sealing ring 8 is provided on the end of the sealing ring 7 near the movable ring 4, the sealing ring 8 and the sealing ring 7 are made of an integral rubber material, and the sealing ring 8 is fixedly connected to the movable ring 4.

[0020] Among them, the inner size of the movable ring 4 is larger than the outer size of the movable ring 4, and one end of the reinforced concrete pipe 1 provided with the movable ring 4 can be easily inserted into the connecting cover 2 of another reinforced concrete pipe 1 to complete the docking.

[0021] Among them, the outer size of the limiting ring 6 is equal to the outer size of the connecting cover 2. When the reinforced concrete pipe 1 is placed on the ground, the same outer size of the limiting ring 6 and the connecting cover 2 can keep the reinforced concrete pipe 1 stable when placed on the ground.

[0022] The distance from the limiting ring to the end surface of the reinforced concrete pipe 1 provided with the movable groove 3 is equal to the width of the connecting cover 2, and the limiting ring limits the depth of the reinforced concrete pipe 1 inserted into another reinforced concrete pipe 1.

[0023] Among them, the sum of the widths of the sealing ring 8 and the movable ring 4 is greater than the width of the connecting cover 2, so that the end of the movable ring 4 will protrude from the end of the reinforced concrete pipe 1. In the process of inserting one end of the reinforced concrete pipe 1 with the movable ring 4 into the connecting cover 2, it will be squeezed and the movable ring 4 will move until it is flush with the end of the reinforced concrete pipe 1.

[0024] Among them, a spring 9 is installed inside the movable groove 3 between the limit ring 6 and the movable block 5, and the two ends of the spring 9 are respectively against the inner wall of the movable ring 4 and the movable groove 3, so that the movable ring 4 is kept protruding from the end of the reinforced concrete pipe 1 by the spring 9.

[0025] Specific working principle:

[0026] When the utility model is in use, the reinforced concrete pipe 1 that needs to be further installed is hoisted by hoisting equipment, and then one end of the reinforced concrete pipe 1 provided with the movable ring 4 is inserted into the installed reinforced concrete pipe 1 connecting cover 2 in the hoisted state. As the reinforced concrete pipe 1 is inserted, the movable ring 4 is squeezed and moves until it is flush with the end face of the reinforced concrete pipe 1. At this time, the end of the connecting cover 2 will abut against the surface of the sealing ring 7. At the same time, in this process, the movement of the movable ring 4 will cause the sealing ring 8 to expand outward and fit the inner wall of the connecting cover 2, and the sealing between the two reinforced concrete pipes 1 is achieved through the sealing ring 7 and the expanded sealing ring 8.

[0027] The implementation modes of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
