Description

Technical Field

[0001] This utility model relates to the field of pipe installation joint technology, and in particular to a pipe installation joint that can be detected and located. Background Technology

[0002] Urban water supply and drainage pipe networks often use cement, cast iron, galvanized steel pipes, or plastic pipes. Due to the long length of the pipes, shorter pipes usually need to be connected. Commonly used quick pipe couplings generally consist of a cast iron shell and a rubber ring. The sealing rubber ring is usually located at both ends of the quick pipe coupling and does not have an anti-detachment structure. Furthermore, the actual sealing position is not at the actual connection point of the pipe.

[0003] Chinese Patent Publication No. CN221374827U discloses an easy-to-install quick pipe coupling, including a central node and a clamping node disposed on the central node. The central node includes a central rubber pad and two central pressure plates. Both central pressure plates are semi-circular and have an installation groove on their inner ring surface. Each of the two central pressure plates has a connecting lug on both sides. The two central pressure plates interlock to clamp the central rubber pad in the installation groove. The central rubber pad includes a central flow channel. The two central pressure plates interlock to form a connecting shaft head. The clamping node includes two clamping pressure plates and a clamping nut. Multiple teeth are arranged side by side on the inner ring surface of the two clamping pressure plates. A connecting block is disposed on each of the left and right sides of the clamping pressure plates. Both the interlocking clamping pressure plate connecting blocks and the interlocking connecting shaft head are provided with threaded structures. The clamping nut is connected to both the threaded structure of the central node and the connecting block in the clamping pressure plate.

[0004] In this existing design, although a central rubber pad can be installed in the mounting groove of the central pressure plate, and the central pressure plate can be used to press the central rubber pad between the two central pressure plates, it can prevent it from being washed away by the water flow under high pressure. By setting two clamping pressure plates, the pipes to be connected can be clamped, and the pipe end face can be pressed against the two end faces of the central rubber pad with the clamping nut to achieve the connection between the pipes. The elastic central rubber pad can effectively seal between the two to prevent liquid leakage. However, during the pipe installation process, the surface of the pipe joint is usually a smooth arc-shaped cast iron or plastic shell. This shape cannot provide any effective support point or reference surface for the measuring ruler. In narrow pipe trenches or complex installation spaces, it is difficult for the measuring personnel to find a stable and flat position to place the measuring tool. The ruler is very easy to tilt or slide due to gravity or slight touch, resulting in repeated measurements or reading deviations.

[0005] To address this issue, a detectable and locating pipe installation joint was designed. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a detectable and locating pipe installation joint that provides a stable reference surface for measuring tools.

[0007] This utility model adopts the following technical solution: a detectable and locating pipe installation joint, including a joint body, connecting threads at both ends of the joint body, a receiving groove on the surface of the joint body, a compression spring fixedly installed inside the receiving groove, a support plate slidably connected inside the receiving groove, a slot on the side of the support plate, a guide block fixedly installed on the side of the support plate, a guide groove on the inner wall of the receiving groove, a groove on the surface of the joint body, a limit rod fixedly installed inside the groove, an insert plate slidably connected to the surface of the limit rod, and a tension spring sleeved on the surface of the limit rod.

[0008] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, the receiving groove is opened in the middle section of the joint body, and there are two sets of grooves, with the two sets of grooves symmetrically opened at both ends of the joint body.

[0009] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, there are two sets of compression springs, and the top ends of both sets of compression springs are connected to the bottom surface of the support plate.

[0010] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, the number of slots is two sets, and the two sets of slots are symmetrically opened on both sides of the support plate.

[0011] In a preferred embodiment of this utility model of a detectable and locating pipe installation joint, the slot and the insert plate are matched in shape and size.

[0012] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, there are two sets of both the guide blocks and the guide grooves, and the two sets of guide blocks and the two sets of guide grooves are symmetrically arranged on both sides of the support plate and the receiving groove.

[0013] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, the guide block is slidably connected inside the guide groove.

[0014] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, one end of the tension spring is fixedly connected to the inner wall of the groove, and the other end of the tension spring is fixedly connected to the side of the insert plate.

[0015] As a preferred embodiment of the detectable and locating pipe installation joint of this utility model, a push plate is fixedly installed on the top surface of the insert plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: a support plate is provided. When measuring the pipe length, by pulling the insert plate, the insert plate is disengaged from the slot. Under the action of the compression spring, the support plate can extend from the receiving groove, thereby providing a support platform for the measuring tool and preventing the measuring tool from tilting or sliding. After the measurement is completed, the support plate can be manually pressed down and re-fixed in the receiving groove with the insert block and slot, integrating the measuring reference with the connector body. No external tools are needed, which improves the accuracy and efficiency of pipe connection length and installation position measurement and reduces the risk of rework or leakage caused by measurement errors.

[0028] Example 1

[0029] In existing technology, readily installable quick-connect pipe fittings include a center node and a clamping node located at the center node. The center node includes a central rubber gasket and two central pressure plates, both of which are semi-circular with an installation groove on their inner surface. Each central pressure plate has a connecting lug on both sides. The two central pressure plates interlock to clamp the central rubber gasket within the installation groove. The central rubber gasket includes a central flow channel. The two central pressure plates interlock to form a connecting shaft. The clamping node includes two clamping plates and a clamping nut. Multiple teeth are arranged side-by-side on the inner surface of the two clamping plates. A connecting block is located on each of the left and right sides of the clamping plates. The interlocking clamping plates have connecting blocks... Both the connecting shaft ends formed by the interlocking are equipped with threaded structures. The clamping nut is connected to the threaded structure of the connecting block in the clamping plate at the same time. This easy-to-install quick pipe coupling can be installed by setting a central rubber gasket and installing the central rubber gasket in the mounting groove of the central pressure plate. The two central pressure plates press the central rubber gasket between them, which can prevent it from being washed away by water flow under high pressure. By setting two clamping pressure plates, the clamping pressure plates are used to clamp the pipes to be connected. With the clamping nut, the end face of the pipe is pressed against the two end faces of the central rubber gasket, realizing the connection between the pipes. The elastic central rubber gasket can effectively seal between the two and prevent liquid leakage.

[0072] Working principle:

[0073] During measurement, first pull the push plate 13. The push plate 13 moves the insert plate 11, stretching the tension spring 12 until the insert plate 11 is disengaged from the slot 6. At this time, the compression spring 4 loses external pressure and, under its own elastic force, can push the support plate 5 out. When the support plate 5 moves, it drives the guide blocks 7 on both sides to slide in the guide groove 8 until the support plate 5 is fully extended. At this time, the guide blocks 7 move to the top of the guide groove 8. Then, the measuring personnel can place the measuring tool on the support plate 5. After the measurement is completed, manually press down the support plate 5 to squeeze the compression spring 4. At the same time, the support plate 5 drives the guide blocks 7 to slide down until the support plate 5 is completely retracted into the receiving groove 3. At this time, release the push plate 13. The tension spring 12 loses external tension and, due to its own tension, can drive the push plate 13 to move. The push plate 13 then drives the insert plate 11 to re-insert into the slot 6, and the support plate 5 is fixed in the receiving groove 3.
