Description

Technical Field

[0001] This utility model belongs to the field of water supply pipeline technology, and in particular relates to a rural drinking water supply pipeline that is easy to connect. Background Technology

[0002] Rural drinking water refers to the drinking water needed by residents in rural areas. Since rural areas often lack natural water sources or have poor water quality, in order to meet the drinking water needs of rural residents, it is necessary to use water supply pipelines to transport treated drinking water to rural areas. In order to ensure the long-distance water transmission needs of the water supply pipelines, it is necessary to connect the water supply pipelines through connectors.

[0003] For example, Chinese patent document (CN115750944A) describes a connection structure for a water supply pipe, which includes a water supply pipe 1 and a water supply pipe 2, as well as a connecting pipe. The inner diameter of the connecting pipe is the same as the outer diameter of the water supply pipe 1, and the inner diameter of the connecting pipe is the same as the outer diameter of the water supply pipe 2. The connecting pipe is provided with a mounting hole 1, a mounting hole 2, and a fixing component. By embedding the water supply pipe 1 and the water supply pipe 2 into the connecting pipe and fixing them with the fixing component, this method is more convenient for connecting the water supply pipe 1 and the water supply pipe 2. Compared with welding, it reduces damage to the water supply pipe 1 and the water supply pipe 2. Furthermore, the connection point of the water supply pipe 1 and the water supply pipe 2 is located on the inner wall of the connecting pipe. The contact between the inner walls of the connecting pipe reduces the leakage of liquid from the connection point of the water supply pipe 1 and the water supply pipe 2. However, during use, the connection position between the pipes is fixed, which cannot adapt to the connection requirements between pipes of different distances, thus affecting the applicability of the product. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the connection positions between pipes are fixed during use, which cannot adapt to the connection needs between pipes of different distances and thus affect the applicability of the product. Therefore, this utility model proposes a rural drinking water supply pipe that is easy to connect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rural drinking water supply pipeline that is easy to connect includes a connecting sleeve. A first drinking water pipeline is provided on one side of the inside of the connecting sleeve, and a second drinking water pipeline is provided on the other side of the inside of the connecting sleeve. A sealing connection component and a limiting and fixing component are respectively provided inside the connecting sleeve.

[0007] The sealing connection assembly includes a connecting frame. Two first cavities are formed at the junction of the connecting frame and the connecting sleeve. A sliding block is slidably connected to the bottom side of the first cavity. The other end of the sliding block extends to the outside of the connecting frame and is fixedly connected to a sealing layer. A fixing block is fixedly connected to one side of the top of the sliding block. An annular cylinder is fixedly connected to the top of the fixing block. Multiple conical blocks are fixedly connected to the top of the annular cylinder. The side of the annular cylinder away from the fixing block extends to the outside of the connecting sleeve and is fixedly connected to a threaded sleeve.

[0008] As a further description of the above technical solution:

[0009] The sliding block is slidably sealed inside the connecting frame, and the cross-sectional shape of the fixed block is set to be annular.

[0010] As a further description of the above technical solution:

[0011] The outer periphery of the connecting frame is fixedly connected to the inner periphery of the connecting sleeve, and the cross-sectional shape of the connecting frame is set to be annular.

[0012] As a further description of the above technical solution:

[0013] The threaded sleeve is threaded to the outer periphery of the first and second drinking water pipes, and the conical block is set as an annular shape.

[0014] As a further description of the above technical solution:

[0015] Both the first and second drinking water pipes have sealing grooves on opposite sides, and the sealing layer is slidably connected inside the sealing grooves.

[0016] As a further description of the above technical solution:

[0017] The limiting and fixing assembly includes an annular block, the inner circumference of which is fixedly connected to the outer circumference of the connecting sleeve. A second cavity is provided at the junction of the annular block and the connecting sleeve, and a threaded rod is provided inside the second cavity.

[0018] As a further description of the above technical solution:

[0019] The threaded rod is threaded inside the annular block, and the top of the threaded rod extends to the outside of the annular block and is fixedly connected to a handle.

[0020] As a further description of the above technical solution:

[0021] The bottom end of the threaded rod is provided with a connecting seat, which is slidably connected inside the second cavity. Mounting brackets are fixedly connected to both sides of the bottom of the connecting seat, and a limit roller is rotatably connected between the two mounting brackets through a connecting shaft and a bearing.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. In this utility model, through the set sealing connection component, the threaded sleeve is manually operated by the operator to rotate on the outer periphery of the first and second drinking water pipes. This causes the threaded sleeve to drive the annular cylinder, conical block, fixed block, sliding block, and sealing layer to move, so that the sealing layer enters the sealing groove. The sliding block provides extended protective connection between the first and second drinking water pipes, making the product suitable for different pipe connection needs and effectively improving the applicability of the product. The sealing layer seals the connection between the sliding block, the first drinking water pipe, and the second drinking water pipe, ensuring the connection sealing of the product during use.

[0024] 2. In this utility model, through the setting of the limiting and fixing component, after the first drinking water pipe and the second drinking water pipe are connected, the operator manually operates the handle to drive the threaded rod to rotate, so that the threaded rod drives the connecting seat, the mounting bracket and the limiting roller to move downward, which helps to limit the installation position of the conical block and the annular cylinder. In conjunction with the threaded sleeve and the threaded connection of the first drinking water pipe and the second drinking water pipe, the connecting sleeve, the first drinking water pipe and the second drinking water pipe are doubly fixed, preventing the threaded sleeve, the first drinking water pipe and the second drinking water pipe from slipping after long-term use, which would affect the installation stability and sealing of the product, thereby effectively improving the performance of the product.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-4 This utility model provides a technical solution: a rural drinking water supply pipe that is easy to connect, including a connecting sleeve 1, a first drinking water pipe 2 is provided on one side inside the connecting sleeve 1, a second drinking water pipe 3 is provided on the other side inside the connecting sleeve 1, and a sealing connection component 4 and a limiting and fixing component 6 are respectively provided inside the connecting sleeve 1.

[0033] The sealing connection assembly 4 includes a connecting frame 401. Two first cavities 402 are formed at the junction of the connecting frame 401 and the connecting sleeve 1. A sliding block 405 is slidably connected to the bottom side of the first cavity 402. The other end of the sliding block 405 extends to the outside of the connecting frame 401 and is fixedly connected to a sealing layer 406. A fixing block 404 is fixedly connected to one side of the top of the sliding block 405. An annular cylinder 403 is fixedly connected to the top of the fixing block 404. Multiple conical blocks 407 are fixedly connected to the top of the annular cylinder 403. The side of the annular cylinder 403 away from the fixing block 404 extends to the connecting... A threaded sleeve 408 is fixedly connected to the outside of the sleeve 1. A sliding block 405 is slidably sealed inside the connecting frame 401. The cross-sectional shape of the fixed block 404 is set as an annular shape. The outer periphery of the connecting frame 401 is fixedly connected to the inner periphery of the connecting sleeve 1, and the cross-sectional shape of the connecting frame 401 is set as an annular shape. The threaded sleeve 408 is threadedly connected to the outer periphery of the first drinking water pipe 2 and the second drinking water pipe 3. The conical block 407 is set as an annular shape. A sealing groove 5 is opened on the opposite side of the first drinking water pipe 2 and the second drinking water pipe 3. The sealing layer 406 is slidably connected inside the sealing groove 5.

[0034] Detailed implementation method: First, place the first drinking water pipe 2 and the second drinking water pipe 3 to be connected onto the two ends of the connecting sleeve 1 respectively. Then, manually operate the threaded sleeve 408 to rotate it on the outer periphery of the first drinking water pipe 2 and the second drinking water pipe 3. This causes the threaded sleeve 408 to move the annular cylinder 403 and the conical block 407. Utilizing the linkage effect between the annular cylinder 403 and the fixed block 404, the power is transmitted to the fixed block 404, causing the fixed block 404 to move the sliding block 405 and the sealing layer 406 towards the first drinking water pipe 2 and the second drinking water pipe 3. This allows the sealing layer 406 to enter the sealing groove 5. The sliding block 405 provides extended protective connection between the first drinking water pipe 2 and the second drinking water pipe 3, making the product suitable for different pipe connection needs and effectively improving the product's applicability. The sealing layer 406 seals the connection between the sliding block 405, the first drinking water pipe 2, and the second drinking water pipe 3, ensuring the connection seal during use.

[0035] The limiting and fixing assembly 6 includes an annular block 601. The inner circumference of the annular block 601 is fixedly connected to the outer circumference of the connecting sleeve 1. A second cavity 602 is provided at the junction of the annular block 601 and the connecting sleeve 1. A threaded rod 603 is provided inside the second cavity 602. The threaded rod 603 is threadedly connected to the inside of the annular block 601, and the top end of the threaded rod 603 extends to the outside of the annular block 601 and is fixedly connected to a handle 604. A connecting seat 605 is provided at the bottom end of the threaded rod 603. The connecting seat 605 is slidably connected inside the second cavity 602. Mounting brackets 606 are fixedly connected to both sides of the bottom of the connecting seat 605. A limiting roller 607 is rotatably connected between the two mounting brackets 606 through a connecting shaft and a bearing.

[0036] Detailed implementation: After connecting the first drinking water pipe 2 and the second drinking water pipe 3, the operator can manually operate the handle 604 to rotate the threaded rod 603 on the annular block 601 as needed. This causes the threaded rod 603 to move the connecting seat 605, the mounting bracket 606, and the limiting roller 607 downwards, assisting in limiting the installation position of the conical block 407 and the annular cylinder 403. This, combined with the threaded connection between the threaded sleeve 408 and the first drinking water pipe 2 and the second drinking water pipe 3, provides double fixation for the connecting sleeve 1, the first drinking water pipe 2, and the second drinking water pipe. This prevents the threaded sleeve 408, the first drinking water pipe 2, and the second drinking water pipe 3 from slipping after prolonged use, which would affect the installation stability and sealing of the product, thereby effectively improving the product's performance.

[0037] Working principle: In use, first place the first drinking water pipe 2 and the second drinking water pipe 3 to be connected onto the two ends of the connecting sleeve 1, respectively. Then, manually operate the threaded sleeve 408 to rotate it on the outer periphery of the first drinking water pipe 2 and the second drinking water pipe 3. This causes the threaded sleeve 408 to move the annular cylinder 403 and the conical block 407. Utilizing the linkage effect between the annular cylinder 403 and the fixed block 404, the power is transmitted to the fixed block 404, causing the fixed block 404 to move the sliding block 405 and the sealing layer 406 towards the first drinking water pipe 2 and the second drinking water pipe 3. This allows the sealing layer 406 to enter the sealing groove 5, and the sliding block 405 expands the seal at the first drinking water pipe 2 and the second drinking water pipe 3. The protective connection is extended, and the sealing layer 406 seals the connection between the sliding block 405, the first drinking water pipe 2, and the second drinking water pipe 3. After the connection between the first drinking water pipe 2 and the second drinking water pipe 3 is made, the operator can manually operate the handle 604 to drive the threaded rod 603 to rotate on the annular block 601 as needed. This causes the threaded rod 603 to drive the connecting seat 605, the mounting bracket 606, and the limiting roller 607 to move downwards, thus helping to limit the installation position of the conical block 407 and the annular cylinder 403. This, together with the threaded sleeve 408 and the threaded connection between the first drinking water pipe 2 and the second drinking water pipe 3, provides double fixation for the connecting sleeve 1, the first drinking water pipe 2, and the second drinking water pipe, ensuring the stability of the product connection.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
