Description

Technical Field

[0001] The utility model relates to the technical field of branch connection pipes, in particular to a temporary branch connection pipe for water supply and drainage. Background Art

[0002] Water supply and drainage refers to the urban water supply system, drainage system (municipal water supply and drainage) and building water supply and drainage. At present, in the process of urban water supply and drainage, it is often necessary to temporarily install water supply and drainage pipelines to supply water or drain water to some areas to meet usage needs.

[0003] The Chinese patent "A temporary branch connection for water supply and drainage" authorization announcement number "CN 220268768U" adds a connecting section tee pipe in the main water pipe to reserve a pre-connection part for the temporary installation of the branch pipe for drainage in the later stage. When installing the branch pipe, first install the two connecting rings in the first positioning groove and the second positioning groove respectively, then abut the positioning rings of the interface section of the branch pipe, and then pass the two pins through the two connecting rings in turn, and finally connect the two connecting rings with the pre-connection part through the external thread on the pin and the threaded nut, so as to avoid the problems of long traditional welding time and low pressure acceptance of plugging or tying, and improve the efficiency of branch pipe connection.

[0004] In the above application, the branch pipe can be installed through the external thread and nut on the pin, but since the branch pipe is used temporarily and is frequently disassembled and assembled, long-term use may cause thread wear. At the same time, when the branch pipe is fixed, the pipeline will vibrate under the action of water flow, which may cause the connection between the nut and the pin to loosen, affecting the stability of the branch pipe connection.

[0005] Therefore, a temporary branch connection of water supply and drainage is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a temporary drainage branch pipe in order to solve the above-mentioned problem, thereby improving the problem that the branch pipe is used temporarily and is frequently disassembled and assembled, and long-term use may cause thread wear. At the same time, when the branch pipe is fixed, the pipe will vibrate under the action of water flow, which may cause the connection between the nut and the pin to loosen, affecting the stability of the branch pipe connection.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions. A temporary branch pipe for water supply and drainage comprises: a main water pipe, a branch pipe and a tee pipe. The two parallel ends of the tee pipe are connected to the main water pipe. The other end of the tee pipe is fixedly connected with a fixing ring. The other end of the fixing ring is threadedly connected with a sealing cover. A fixing mechanism is arranged inside the fixing ring. The fixing mechanism comprises a mounting ring fixedly connected to one end of the branch pipe. The other end of the mounting ring is fixedly connected with a fixing block. A card groove is provided on the outer surface of the fixing block. An arc groove is provided on the inner wall of the mounting ring. A first spring is fixedly connected to the inner wall of the arc groove. A card plate is fixedly connected to the bottom end of the first spring. A fixing component is arranged on the top of the card plate.

[0008] Preferably, the fixing assembly comprises a round rod fixedly connected to the upper end of the surface of the clamping plate, a push block is slidably connected to the inner wall of the round rod, a second spring is fixedly connected between one side of the push block and the inner wall of the round rod, and an extrusion block is fixedly connected to the inner wall of the mounting ring. Under the action of the inclined surface of the push block, the second spring and the inclined surface of the extrusion block, the top end of the push block is pressed against the bottom end of the extrusion block, which is conducive to re-fixing the round rod and the clamping plate, thereby preventing the mounting ring and the branch pipe from moving in the vertical direction.

[0009] Preferably, the fixing assembly further comprises two fixed arc plates, the inner surface of the arc plates are fixedly connected with two connecting plates, the surface of the mounting ring and the surface of the fixing ring are both provided with annular grooves, both ends of the arc plates are fixedly connected with mounting plates, and the two vertical mounting plates are fixed by bolts. In the process of fixing the fixing ring and the mounting ring by bolts and two arc plates, it is beneficial for the connecting plate to push the round rod downward to press against the clamping plate, thus ensuring the stability when the clamping plate is clamped with the clamping groove, and at the same time, it is beneficial to complete the re-positioning of the round rod and the fixing block.

[0010] Preferably, the other side of the push block forms an angle with the horizontal plane, the vertical section of the extrusion block is a right triangle, and the inclination angle of the extrusion block slope is the same as the inclination angle of the push block slope, which is conducive to making the slope of the extrusion block better squeeze the push block and make the push block move horizontally.

[0011] Preferably, the other end of the mounting ring is fixedly connected with a circular ring, and the outer diameter of the circular ring is the same as the inner diameter of the fixing ring, which is conducive to limiting the mounting ring and the fixing ring during installation and avoiding misalignment of the fixing ring and the mounting ring.

[0012] Preferably, a sealing gasket is fixedly connected to the other end of the mounting ring, and the sealing gasket is a rubber component, so as to ensure the sealing performance when the fixing ring and the mounting ring are installed.

[0013] Preferably, the surface of the fixing block is curved in an arc shape, and the curvature of the surface of the card plate is the same as the curvature of the inner wall of the card slot, which is conducive to better carding the card plate to the card slot.

[0014] Preferably, one side of the outer surface of the fixing block and one side of the inner surface of the card plate are both curved in an arc shape. When the fixing block is inserted into the arc groove, it is beneficial for the fixing block to better push the card plate to move upward.

[0015] The beneficial effects of the utility model are:

[0016] 1. When installing the branch pipe, by inserting the fixing block into the arc groove, under the action of the first spring, it is conducive to automatically clamping the clamping plate with the fixed clamping groove to complete the fixing of the fixing block, avoiding the horizontal movement of the mounting ring and the branch pipe. At the same time, in the process of fixing the fixing ring and the mounting ring with bolts and two arc plates, it is conducive to driving the round rod to drive the push block to move downward. Under the action of the inclined surface of the push block, the second spring and the inclined surface of the extrusion block, the top end of the push block is pressed against the bottom end of the extrusion block, which is conducive to fixing the round rod and the clamping plate again, thereby avoiding the vertical movement of the mounting ring and the branch pipe, and ensuring the stability of the branch pipe during installation;

[0017] 2. After the two arc-shaped plates are fixed with bolts, it is helpful for the connecting plate to push the round rod downward to press against the clamping plate, thereby ensuring the stability of the clamping plate when it is clamped with the clamping slot, thereby ensuring the stability of the clamping plate when it is fixed.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a temporary branch connection for water supply and drainage comprises: a main water pipe 1, a branch pipe 2 and a tee pipe 3, wherein the two parallel ends of the tee pipe 3 are connected to the main water pipe 1, the other end of the tee pipe 3 is fixedly connected with a fixing ring 4, the other end of the fixing ring 4 is threadedly connected with a sealing cover 5, and a fixing mechanism 6 is arranged inside the fixing ring 4; wherein the fixing mechanism 6 comprises a mounting ring 601 fixedly connected to one end of the branch pipe 2, the other end of the mounting ring 601 is fixedly connected with a fixing block 602, a groove 603 is provided on the outer surface of the fixing block 602, an arc groove 604 is provided on the inner wall of the mounting ring 601, a first spring 605 is fixedly connected to the inner wall of the arc groove 604, the bottom end of the first spring 605 is fixedly connected with a clamping plate 606, and a fixing component 607 is arranged on the top of the clamping plate 606.

[0026] A thread groove is formed at the other end of the fixing ring 4. When the device is in the initial state, the thread ring of the sealing cover 5 is threadedly connected to the thread groove of the fixing ring 4 to seal the other end of the tee pipe 3. The arc groove 604 is connected to the thread groove.

[0027] When the branch pipe 2 needs to be installed, the seal of the sealing cover 5 is released, and then the fixing block 602 at the other end of the mounting ring 601 is aligned with the arc groove 604. At this time, the mounting ring 601 is pushed to make the fixing block 602 enter the arc groove 604, and the clamping plate 606 is squeezed to move upward so that the inner surface of the clamping plate 606 fits with the outer surface of the fixing block 602. The first spring 605 contracts. When the clamping plate 606 and the clamping groove 603 are in the same vertical plane, under the action of the first spring 605, the clamping plate 606 will enter the clamping groove 603 for clamping, thereby completing the fixation of the mounting ring 601 and the branch pipe 2 and preventing the mounting ring 601 and the branch pipe 2 from moving horizontally.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixing assembly 607 includes a round rod 6071 fixedly connected to the upper end of the surface of the clamping plate 606, a push block 6072 is slidably connected to the inner wall of the round rod 6071, a second spring 6073 is fixedly connected between one side of the push block 6072 and the inner wall of the round rod 6071, and an extrusion block 6074 is fixedly connected to the inner wall of the mounting ring 601. The fixing assembly 607 also includes two fixed arc plates 6075, two connecting plates 6076 are fixedly connected to the inner surface of the arc plates 6075, annular grooves 6078 are provided on the surface of the mounting ring 601 and the surface of the fixing ring 4, and mounting plates 6077 are fixedly connected to both ends of the arc plates 6075, and the two vertical mounting plates 6077 are fixed by bolts.

[0029] The top of the push block 6072 is on the same horizontal plane as the top of the round rod 6071 , and a sliding groove matching the push block 6072 is provided on the top of the round rod 6071 .

[0030] After completing the above operations, the two connecting plates 6076 on the inner surfaces of the two arc-shaped plates 6075 are respectively inserted into the corresponding annular grooves 6078 on the surfaces of the fixing ring 4 and the mounting ring 601. The connecting plate 6076 is a half ring. When the connecting plate 6076 is clamped into the corresponding annular groove 6078, at this time, the inner surface of the connecting plate 6076 clamped in the annular groove 6078 on the surface of the fixing ring 4 fits with the top end of the round rod 6071. The two mounting plates 6077 at both ends of the two arc-shaped plates 6075 are fixed by bolts and nuts respectively. During the fixing process, the round rod 6071 will be pushed to move downward, so that the round rod 6071 pushes the clamping plate 606 to press against the clamping groove 603. At the same time, the round rod 6071 will drive the push block 6072 to move downward, so that the top end of the push block 6072 contacts the bottom end of the extrusion block 6074, completing the re-positioning of the fixing block 602 to prevent the mounting ring 601 and the branch pipe 2 from moving in the vertical direction.

[0031] like Figure 3As shown, the other side of the push block 6072 forms an angle with the horizontal plane, the vertical section of the extrusion block 6074 is a right triangle, and the inclination angle of the inclined surface of the extrusion block 6074 is the same as the inclination angle of the inclined surface of the push block 6072. In the initial state of the device, the inclined surface of the push block 6072 fits the inclined surface of the extrusion block 6074. When the round rod 6071 drives the push block 6072 to move downward, under the action of the push block 6072 and the inclined surface of the extrusion block 6074, the push block 6072 will move into the round rod 6071 and compress the second spring 6073. When the two arc plates 6075 are fixed, the inclined surface of the push block 6072 is no longer in contact with the inclined surface of the extrusion block 6074, and automatically resets under the action of the second spring 6073.

[0032] like Figure 4 As shown, the other end of the mounting ring 601 is fixedly connected with a circular ring 608, and the outer diameter of the circular ring 608 is the same as the inner diameter of the fixing ring 4. When the branch pipe 2 needs to be installed, the circular ring 608 at the other end of the mounting ring 601 is inserted into the fixing ring 4, the surface of the circular ring 608 is in contact with the inner wall of the fixing ring 4, and the other end of the circular ring 608 is in contact with the other end of the tee pipe 3.

[0033] like Figure 4 As shown, the other end of the mounting ring 601 is fixedly connected with a sealing gasket 609, which is a rubber component. The inner wall of the sealing gasket 609 is fixedly connected to the surface of the fixing block 602. When the mounting ring 601 and the fixing ring 4 are installed, the surface of the sealing gasket 609 fits with the other end of the fixing ring 4.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the surface of the fixing block 602 is curved, and the curvature of the surface of the clamping plate 606 is the same as the curvature of the inner wall of the clamping slot 603. The curvatures of the fixing block 602, the arc slot 604 and the clamping plate 606 are the same, and the size of the clamping plate 606 matches the size of the clamping slot 603.

[0035] like Figure 3 and Figure 4 As shown, one side of the outer surface of the fixing block 602 and one side of the inner surface of the clamping plate 606 are both curved in an arc shape. The curvature of the outer surface of the fixing block 602 is the same as the curvature of the inner surface of the clamping plate 606. When the fixing block 602 is inserted into the arc groove 604, the curved surface of the fixing block 602 contacts the curved surface of the clamping plate 606 and squeezes the clamping plate 606 to move upward.

[0036] When the utility model is used, when installing the branch pipe 2, the seal of the sealing cover 5 is released, and the ring 608 is inserted into the fixing ring 4, and the fixing block 602 is simultaneously entered into the arc groove 604, and the clamping plate 606 is squeezed to move upward, and the first spring 605 contracts. When the surface of the sealing gasket 609 is pressed against the other end of the fixing ring 4, the clamping plate 606 and the clamping groove 603 are on the same vertical plane. Under the action of the first spring 605, the clamping plate 606 automatically enters the clamping groove 603 for clamping, and the fixing of the fixing block 602 is completed, thereby preventing the installation ring 601 and the branch pipe 2 from moving in the horizontal direction. After completing this operation, the two connecting plates 6075 on the inner surfaces of the two arc plates 6075 are 76 are respectively engaged with the annular grooves 6078 corresponding to the surfaces of the fixing ring 4 and the mounting ring 601, and the two mounting plates 6077 at both ends of the two arc plates 6075 are respectively fixed by bolts and nuts. During this process, the round rod 6071 will be pushed to move downward to push the clamping plate 606 to press against the clamping groove 603. At the same time, the round rod 6071 will drive the push block 6072 to move downward and the push block 6072 will move away from the extrusion block 6074. When the two arc plates 6075 are fixed, the top end of the push block 6072 contacts the bottom end of the extrusion block 6074, completing the re-positioning of the round rod 6071 and the fixing block 602, thereby preventing the mounting ring 601 and the branch pipe 2 from moving in the vertical direction.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
