Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically a pipeline structure for drainage in urban and rural planning. Background Technology

[0002] Drainage pipes are an important part of urban and rural planning. In the construction and maintenance of drainage pipes, there is a high demand for quick assembly and disassembly. Existing technology meets the demand for quick assembly and disassembly through quick-assembly structures. The existing quick-assembly structures include a sealing gasket, a clamp, and two quick-assembly plates. Each quick-assembly plate is fixed to the end of the pipe, and a sealing gasket is placed between the two quick-assembly plates. The two quick-assembly plates are covered with clamps. The quick-assembly plates have bevels. By closing the clamps and squeezing the bevels, the quick-assembly plates are driven to clamp the sealing gasket to achieve a sealing effect.

[0003] When using existing quick-installation structures between horizontal pipes, installers first place the gasket between two quick-installation pieces. Due to the characteristics of horizontal pipes, the gasket is prone to falling off. Installers need to apply force along the pipe axis to clamp the gasket between the quick-installation pieces. After clamping the gasket, installers need to put the clamps on the quick-installation pieces. When putting on the clamps, installers need to hold the clamps to prevent them from falling off while closing them. Throughout the process, installers must keep the quick-installation pieces clamped, prevent the clamps from falling off, and close the clamps. The operation is difficult and labor-intensive, reducing installation efficiency. Therefore, it is necessary to design a quick-installation structure for drainage pipes with lower operation difficulty for installing horizontal pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe structure for drainage in urban and rural planning, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe structure for drainage in urban and rural planning, comprising two pipes, each pipe having a quick-release plate fixed at its end, one of the pipes having a pipe clamp detachably fixed on it, a connecting plate fixed below the pipe clamp, one end of a spring fixed below the connecting plate, and the other end of the spring fixed on a support.

[0006] The connecting plate has a fixed end of a blocking plate, which can be bent. A step is fixed on the support. In its free state, the blocking plate is located outside the step, and the free end of the blocking plate can be inserted between the step and the spring.

[0007] A passive clamp is fixed on the support. One end of the passive clamp is rotatably connected to the other end of the movable clamp. The other end of the passive clamp is rotatably connected to a screw. A nut is threaded onto the screw. The other end of the movable clamp has a U-shaped notch.

[0008] Preferably, when the free end of the blocking plate is inserted between the step and the spring, the free end of the blocking plate can contact the spring.

[0009] Preferably, the baffle plate is made of spring steel.

[0010] Preferably, the pipe clamp includes two metal strips, and the two ends of the connecting plate are respectively fixed with the fixed end of one of the metal strips. One of the metal strips has a threaded hole at its free end, and the other metal strip has a screw threadedly connected to its free end. The screw can be threadedly connected to the threaded hole.

[0011] Preferably, the side of the step away from the spring is an inclined plane.

[0012] Preferably, a handle is fixed to the nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the passive clamp is fixed on the support, and the spring in its free state can bring the support closer to the connecting plate, thereby driving the passive clamp closer to the connecting plate. The connecting plate is fixed under the pipe clamp. When the pipe clamp is fixed on the horizontal pipe, the passive clamp can approach the pipe clamp, and then approach the pipe, preventing the passive clamp from falling off. It is no longer necessary for the installer to hold the clamp to prevent it from falling off, making it easier for the installer to put on the clamp, reducing the difficulty of operation, reducing labor intensity, and improving installation efficiency.

[0014] Before placing the sealing gasket, the installer first pulls out the passive clamp, which moves the support and extends the spring. To prevent the spring from retracting, the free end of the baffle plate is pushed between the spring and the step, keeping the passive clamp in the pulled-out state. This allows the passive clamp to be positioned away from the pipe, making it easier for the operator to fine-tune the position of the pipe end and to place the sealing gasket between the quick-release plates.

[0015] After the installer places the sealing gasket, they apply force along the pipe axis to clamp the gasket with the quick-release plate. With the gasket clamped, they shake the support to separate the step from the baffle plate. Then the spring shortens, which moves the support and causes the passive clamp to retract, pressing the quick-release plate against the pipe. The cooperation of these parts makes it easier for the passive clamp to approach the pipe, facilitating the installer's operation. Attached Figure Description

[0020] 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.

[0021] This utility model provides a technical solution: a pipe structure for drainage in urban and rural planning, such as... Figure 1 , 2 As shown, it includes two pipes 1, each of which has a quick-release plate 2 fixed at its end. One of the pipes 1 is detachably fixed with a pipe clamp 20, and a connecting plate 3 is fixed below the pipe clamp 20. One end of a spring 4 is fixed below the connecting plate 3, and the other end of the spring 4 is fixed to a support 5.

[0022] The passive clamp 7 is fixed on the support 5. When the spring 4 is in a free state, it can bring the support 5 closer to the connecting plate 3, thereby driving the passive clamp 7 closer to the connecting plate 3. Since the connecting plate 3 is fixed under the pipe clamp 20, when the pipe clamp 20 is fixed on the horizontal pipe 1, under the action of the spring 4, the passive clamp 7 can approach the pipe clamp 20, and then approach the pipe 1, preventing the passive clamp 7 from falling off. It is no longer necessary for the installer to hold the clamp to prevent it from falling off, making it easier for the installer to put on the clamp, reducing the difficulty of operation, reducing labor intensity, and improving installation efficiency.

[0023] The connecting plate 3 has a fixed end of a blocking plate 6, which is bendable. A step 13 is fixed to the support 5 (shown in...). Figure 3 In the middle), the blocking plate 6 is located outside the step 13 in a free state, and the free end of the blocking plate 6 can be inserted between the step 13 and the spring 4.

[0024] The fixed end of the blocking plate 6 is fixed under the connecting plate 3. Before placing the sealing gasket, the installer first pulls out the passive clamp 7, which in turn moves the support 5 and causes the spring 4 to extend. In order to prevent the spring 4 from retracting, the free end of the blocking plate 6 is pushed between the spring 4 and the step 13 to keep the passive clamp 7 in the pulled-out state. This allows the passive clamp 7 to be in a position away from the pipe 1 and the quick-release plate 2, making it convenient for the operator to fine-tune the position of the end of the pipe 1 and to place the sealing gasket between the quick-release plates 2.

[0025] After the installer places the sealing gasket between the quick-release pieces 2, they apply force along the axis of the pipe 1 to clamp the sealing gasket between the quick-release pieces 2. With the sealing gasket clamped, the support 5 is shaken to separate the step 13 and the spring 4 from the blocking plate 6. Then the spring 4 shortens, which in turn moves the support 5, causing the passive clamp 7 to retract and press the quick-release piece 2 against the pipe 1. The cooperation of the above parts makes it easier for the passive clamp 7 to approach the pipe 1, which is convenient for the installer to operate.

[0026] A passive clamp 7 is fixed on the support 5. One end of the passive clamp 7 is rotatably connected to one end of a movable clamp 8. The other end of the passive clamp 7 is rotatably connected to a screw 9. A nut 10 is threaded onto the screw 9. A U-shaped notch 11 is provided at the other end of the movable clamp 8.

[0027] After the passive clamp 7 presses the quick-release plate 2, the installer rotates the movable clamp 8 to close the passive clamp 7 and the movable clamp 8. Then, the screw 9 of the passive clamp 7 is rotated to insert the screw 9 into the U-shaped notch 11 of the movable clamp 8. Then, the nut 10 is rotated to press the nut 10 into the U-shaped notch 11, thereby closing the active clamp and the passive clamp 7. This causes the inclined surface of the quick-release plate 2 to be compressed, thereby clamping the sealing gasket to achieve a sealing effect and completing the installation of the horizontal pipe 1. By rotating the movable clamp 8 onto the passive clamp 7, it is convenient for the operator to put on the movable clamp 8.

[0028] like Figure 1 , 3 As shown, when the free end of the blocking plate 6 is inserted between the step 13 and the spring 4, the free end of the blocking plate 6 can contact the spring 4. When the free end of the blocking plate 6 is inserted between the step 13 and the spring 4, the tension of the spring 4 on the support 5 is converted into a torque on the blocking plate 6. The fulcrum of the torque is at the free end of the blocking plate 6. By making the free end of the blocking plate 6 contact the spring 4, the lever arm of the torque applied by the spring 4 on the blocking plate 6 can be reduced to the greatest extent, avoiding the blocking plate 6 from popping out accidentally, which in turn causes the spring 4 to shorten, thereby causing the passive clamp 7 to retract and improving the stability of the passive clamp 7 in the pulled-out state.

[0029] To facilitate bending of the baffle plate 6, the baffle plate 6 is made of spring steel.

[0030] like Figure 1 , 2 As shown, the pipe clamp 20 includes two metal strips 21. The two ends of the connecting plate 3 are respectively fixed with the fixed end of one of the metal strips 21. One of the metal strips 21 has a threaded hole at its free end, and the other metal strip 21 has a screw 22 threadedly connected to its free end. The screw 22 can be threadedly connected to the threaded hole.

[0031] When installing the pipe clamp 20, first wrap the metal strip 21 around the pipe 1, then insert the screw 22 into the threaded hole, and then tighten the screw 22 to make the metal strip 21 hug the pipe 1.

[0032] like Figure 3 As shown, in order to facilitate pushing the free end of the blocking plate 6 between the step 13 and the spring 4, the side of the step 13 away from the spring 4 is an inclined surface. When the blocking plate 6 is pushed, the blocking plate 6 passes over the inclined surface of the step 13 and enters between the step 13 and the spring 4.

[0033] like Figure 1 As shown, a handle 12 is fixed on the nut 10 to facilitate tightening.

[0034] Working process: When installing the horizontal pipe 1, the installer first puts the pipe clamp 20 on the pipe 1, then moves the support 5 below the quick-release plate 2, and then fixes the pipe clamp 20 on the pipe 1. Then the passive clamp 7 is pulled out, which drives the support 5 to move, which in turn drives the spring 4 to extend. In order to prevent the spring 4 from retracting, the free end of the blocking plate 6 is pushed between the step 13 and the tension spring 4 to keep the passive clamp 7 in the pulled-out state.

[0035] When the passive clamp 7 is in the pulled-out state, the installer places the sealing gasket between the two quick-release plates 2, and then applies force along the axis of the pipe 1 to make the quick-release plates 2 clamp the sealing gasket. With the sealing gasket clamped, the support 5 is shaken to separate the step 13 from the baffle plate 6. Then the spring 4 is shortened, which in turn drives the support 5 to move, which in turn drives the passive clamp 7 to retract, so that the passive clamp 7 presses the quick-release plates 2.

[0036] After the passive clamp 7 presses the quick-release plate 2, the installer rotates the movable clamp 8 to close the passive clamp 7 and the movable clamp 8. Then, the screw 9 of the passive clamp 7 is rotated to insert the screw 9 into the U-shaped notch 11 of the movable clamp 8. Then, the nut 10 is rotated to press the nut 10 into the U-shaped notch 11, thereby closing the active clamp and the passive clamp 7. This causes the inclined surface of the quick-release plate 2 to be compressed, thereby clamping the sealing gasket to achieve a sealing effect and completing the installation of the horizontal pipe 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
