Description

Technical Field

[0001] This utility model relates to the field of pipe connector technology, and in particular to a single-row pipe connector for buried cable protective sleeves. Background Technology

[0002] Pipe connector technology is an engineering technology that achieves rapid connection and sealing of pipes through mechanical or physical means, and is widely used in water conservancy, energy, chemical and other fields. Its core lies in using structures such as flanges, clamps, welding or flexible seals to balance axial displacement, angular deflection and pressure differences between pipes, ensuring the stability of media transmission. Single-row pipe connectors are a sub-type of pipe connector technology, specifically designed for single-line straight pipes or short-distance parallel pipes, and are commonly found in domestic water supply, small HVAC systems and other scenarios.

[0003] However, in the existing technology, the two clips of some single-row tube connectors need to be pressed one by one to release the engagement state. However, due to the special nature of the two clips, the engagement state of the two clips must be released at the same time, which makes the process cumbersome and time-consuming.

[0004] Therefore, a single-row pipe connector for buried cable protection sleeves is proposed to address the above-mentioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a single-row pipe connector for buried cable protection sleeves, which aims to improve the problem that in some existing single-row pipe connectors, the two buckles need to be pressed one by one to release the engagement state. However, due to the special nature of the two buckles, they must be released simultaneously, resulting in a cumbersome and time-consuming process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A single-row pipe connector for buried cable protection sleeve includes two bundled tubes. Two locking blocks are fixedly connected to one side of each bundled tube, and a locking groove for engaging with the locking blocks is opened on the other side of each bundled tube. Two support blocks are fixedly connected to the side of each bundled tube away from the locking blocks. A sliding rod is fixedly connected to the inner wall of the two support blocks. Two pull columns are slidably connected to the outside of each sliding rod. A sliding plate is fixedly connected to the inner side of each pull column, and a baffle is fixedly connected to the inner side of each sliding plate. A spring is sleeved on the outside of each sliding rod.

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

[0009] Two sealing gaskets, which are rubber sealing gaskets, are fixedly connected to the inner wall of the bundle tube.

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

[0011] The two bundle tubes are engaged with the slots in opposite directions by a locking block, and one side of the pull post is slidably connected to the outside of the bundle tubes;

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

[0013] One side of the slide plate is slidably connected to the outside of the bundle tube, and one side of the baffle is slidably connected to the outside of the bundle tube.

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

[0015] The two ends of the spring are respectively fixedly connected to the adjacent sides of the two pull columns;

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

[0017] One side of one of the skateboards is slidably connected to the other side of the skateboard.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, when installing two bundled tubes, they can be simply snapped together. When disassembly is required, simply pinch the two pull posts with one hand, causing them to slide towards each other on the slide rod. This simultaneously drives the two slide plates and baffles to move towards each other, causing the two baffles to press the locking blocks together until they disengage from the locking grooves on the bundled tubes. Compared to the prior art, which requires pressing the locking blocks separately to unlock the engagement, this design reduces the number of steps and improves the efficiency of disassembly.

[0020] 2. In this utility model, a sealing gasket is added to the inner wall of the bundle tube. When the two bundle tubes are joined, the sealing gasket will be squeezed and deformed due to its rubber material, which makes the two bundle tubes fit more tightly, improving the sealing performance and ensuring the stability of the engagement between the two bundle tubes.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1 to 3 This utility model provides an embodiment of a single-row pipe connector for buried cable protection sleeves, comprising two bundled tubes 1, which serve as the connector body for connecting two single-row pipes. Two locking blocks 2 are fixedly connected to one side of the bundled tube 1, and a locking groove is provided on the other side of the bundled tube 1 to engage with the locking blocks 2. The two bundled tubes 1 are engaged with the locking blocks 2 and the locking groove in opposite directions. After the locking blocks 2 and the locking groove are engaged, the two bundled tubes 1 can be used to connect the two single-row pipes together. Two support blocks 3 are fixedly connected to the side of the bundled tube 1 away from the locking blocks 2. A sliding rod 4 is fixedly connected to the inner wall of the two support blocks 3, providing stable support for the sliding rod 4. Two pull posts 5 are slidably connected to the outside of the sliding rod 4. One side of the pull post 5 is slidably connected to the outside of the bundled tube 1, and a sliding plate 6 is fixedly connected to the inside of the pull post 5. One side of one sliding plate 6 is slidably connected to the side of the other sliding plate 6. When the two pull posts 5 are pulled, the sliding plates 6 can be moved together in the same direction.

[0029] One side of the slide plate 6 is slidably connected to the outside of the bundle tube 1. A baffle 7 is fixedly connected to the inside of the slide plate 6. The baffle 7 moves with the slide plate 6. One side of the baffle 7 is slidably connected to the outside of the bundle tube 1. A spring 8 is sleeved on the outside of the slide rod 4. The spring 8 is in a neutral state. When it is necessary to open the bundle tube 1 to remove the two single-row tubes, simply pinch the two pull posts 5 on both sides of the bundle tube 1 with both hands and move them towards each other. At this time, the pull posts 5 will drive the slide plate 6 to move, and the slide plate 6 will further drive the baffle 7 to move together, thereby squeezing the two locking blocks 2 and disengaging them from the locking slots. By operating with both hands simultaneously, all four locking blocks 2 can be disengaged from the locking slots at the same time, which greatly reduces the number of steps and the time consumed, and improves the efficiency of disassembly. The two ends of the spring 8 are fixedly connected to the adjacent sides of the two pull posts 5. The spring 8 here is mainly used for the reset operation of the pull posts 5. When the two pull posts 5 move towards each other, they will pull the spring 8, which will generate force. After releasing the hands, the pull posts 5 will be reset under the pull of this force.

[0030] Reference Figure 4 Two sealing gaskets 9 are fixedly connected to the inner wall of the bundle tube 1. The sealing gaskets 9 are rubber sealing gaskets. Because the rubber material itself has a certain elasticity, when the two bundle tubes 1 are combined, they will squeeze the sealing gaskets 9, thereby making the two sealing gaskets 9 fit more tightly, improving the sealing performance and ensuring the stability when the two bundle tubes are engaged.

[0031] Working Principle: During normal operation, the two bundle tubes 1 form a closed structure through reverse interlocking. The internal locking blocks 2 are embedded in the corresponding slots. Combined with the elastic deformation of the rubber sealing gasket 9, this ensures both connection stability and improved sealing. During disassembly, the operator pulls the two pull posts 5 with both hands, causing them to move towards each other. Guided by the sliding rod 4 and the sliding plate 6, the baffle 7 presses the locking block 2 inward, breaking the interlocking state. Specifically, when the pull post 5 slides along the outside of the bundle tube 1, the sliding plate 6 on its inner side moves synchronously due to mutual contact, driving the baffle 7 to move along the inner wall of the bundle tube 1, directly applying pressure to the locking block 2 and causing it to disengage from the slot. At this time, the sliding rod 4 provides stable support for the sliding plate 6, ensuring the straightness of the movement trajectory. The spring 8 is stretched and stores energy during the movement of the pull post 5. After releasing the tension, it drives the pull post 5 to reset and return to its initial state. The sealing gasket 9 is deformed under pressure when the bundle tube 1 is closed, filling the gap and enhancing the seal. At the same time, its elastic properties assist in the positioning of the locking block 2, improving the reliability of the connection. The entire process utilizes the lever principle and elastic elements to simultaneously unlock the four locking blocks 2 with a single hand, significantly improving disassembly and assembly efficiency.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
