[0031] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 7As shown, a municipal water supply mud well node connection structure, through the setting of the connecting mechanism 4, makes the connection between the connecting plug 2 and the slave pipe 3 faster, and the mutual connection can be achieved by turning the handle 404. When dismantling, it is necessary to pull out the unlocking rod 8 first, and then turn the handle 404 in the opposite direction to achieve the separation of the connecting plug 2 and the slave pipe 3, which is convenient for installation and disassembly. Specifically, it includes a main pipe extending in the up and down directions (the structure of the main pipe is the same as that of the slave pipe 3, so the main pipe can be inserted into the main connector 201), the lower end of the main pipe is sleeved with a connecting plug 2, and the connecting plug 2 is respectively connected to the slave pipe 3 (the end of the slave pipe 3 close to the main pipe is provided with a plug connector, and the outer diameter of the plug connector is mutually adapted to the inner diameter of the slave connector 202, so that the slave pipe 3 can be inserted into the slave connector 202), the main pipe and the slave pipe 3 are used for mud discharge processing, and when the main pipe and the slave pipe 3 are connected to each other, the mud discharge function can be achieved.

[0033] A rubber sheet is provided at one end of the secondary pipe 3 close to the connecting plug 2, and the provision of the rubber sheet enables it to play a role of sealing and protection.

[0034] The connecting plug 2 includes a main connector 201 and a slave connector 202. There are multiple slave connectors 202, which are arranged in a circular array with the main connector 201 as the center. The slave connectors 202 can be added or reduced according to needs.

[0035] A cavity 6 is provided inside the slave connector 202 and the master connector 201 , and each connecting mechanism 4 is disposed in the cavity 6 .

[0036] By putting the support frame 9 on the main pipeline, the support frame 9 is located below the slave pipeline 3. While being connected to each other, it can also support the slave pipeline 3. Specifically, a plurality of spaced connection mechanisms 4 are provided in the connecting plug 2. The connection mechanism 4 includes a screw 401 and a transmission rod 403 rotatably installed inside the cavity 6. The upper end of the transmission rod 403 rotates to pass through the connecting plug 2 and is fixedly connected with a handle 404. By turning the handle 404, the handle 404 can drive the transmission rod 403 to rotate. The screw 401 and the transmission rod 403 are connected by a bevel gear set 402 (the bevel gear set 402 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly arranged on the screw 401, and the second bevel gear is fixedly arranged on the transmission rod 403. The first bevel gear and the second bevel gear are meshed with each other). Since the screw 401 and the transmission rod 403 are connected by the bevel gear set 402, the screw 401 can be driven to rotate.

[0037] One end of the screw rod 401 away from the transmission rod 403 rotates to pass through the connecting plug 2 and is inserted into the threaded hole 5. When the screw rod 401 rotates, it is used to drive the slave pipe 3 to move closer to one side of the connecting plug 2. When the screw rod 401 rotates, it can adapt to the threaded hole 5, so that the slave pipe 3 moves closer to one side of the connecting plug 2 and squeezes the rubber to achieve the connection between the slave pipe 3 and the connecting plug 2.

[0038] The setting of the locking mechanism 7 enables the handle 404 to be locked without the action of external force, thereby preventing the handle 404 from automatically detaching from the stage pipe 3 and the connecting plug 2. Specifically, the locking mechanism 7 is provided in the cavity 6, and the locking mechanism 7 is connected to the screw 401 in a transmission manner.

[0039] The locking mechanism 7 includes a ratchet 701 and a pawl 702 . The ratchet 701 is fixed on the screw 401 . The ratchet 701 and the pawl 702 are connected to each other. When the screw 401 rotates, the ratchet 701 can be driven to rotate to achieve the connection between the secondary pipe 3 and the connecting plug 2 .

[0040] The pawl 702 is rotatably arranged in the cavity 6, and an unlocking rod 8 extending in the up and down directions is hingedly connected to the pawl 702. The unlocking rod 8 slides out of the connecting plug 2, and the unlocking rod 8 is used to release the cooperation between the pawl 702 and the ratchet 701. When it is necessary to release the connection between the level pipe 3 and the connecting plug 2, the unlocking rod 8 is first pulled upward. During the process of pulling the unlocking rod 8 upward, the pawl 702 is driven to rotate, so that the pawl 702 is disengaged from the tooth groove of the ratchet 701, and then the handle 404 is reversed to achieve the connection between the level pipe 3 and the connecting plug 2.

[0041] A threaded hole 5 opening toward the connecting plug 2 is provided on one side of the secondary pipe 3 close to the connecting plug 2, and a connecting mechanism 4 is connected to the threaded hole 5, and the connecting mechanism 4 and the threaded hole 5 cooperate with each other to connect the connecting plug 2 and the secondary pipe 3 to each other.

[0042] Under the action of the clamping assembly, the connecting plug 2 and the slave-level pipe 3 to be connected can be clamped, so as to avoid tilting or deviation of the connecting plug 2 and the slave-level pipe 3 during the connection process, and under the action of the clamping plate 1003, it can support the connecting plug 2 and the slave-level pipe 3 to improve the stability of the pipe connection. Specifically, a support frame 9 is provided under the connecting plug 2, and the main-level support frame 901 is under the main pipe to support the main pipe, and the slave-level support frame 902 is placed under the slave-level pipe 3.

[0043] The support frame 9 is provided with a plurality of clamping assemblies for clamping the connecting plug 2 and the secondary pipe 3. The clamping assemblies are clamped at the connection between the connecting plug 2 and the secondary pipe 3 so that the connecting plug 2 and the secondary pipe 3 maintain the same height.

[0044] The support frame 9 includes a main support frame 901 and a secondary support frame 902. There are multiple secondary support frames 902, which are fixed on the outer side of the main support frame 901. Both the main support frame 901 and the secondary support frame 902 are opened upward.

[0045] The clamping components are respectively arranged in the slave support frame 902, and the slave support frame 902 is used to support the connection between the slave pipe 3 and the connecting plug 2.

[0046] The clamping assembly includes a telescopic sleeve 1001 (the telescopic sleeve 1001 includes a sleeve and a sleeve rod, and the sleeve rod is slidably arranged in the sleeve), a spring 1002 (one end of the spring 1002 is fixedly connected to the inner bottom wall of the sleeve, and the other end of the spring 1002 is fixedly connected to one end of the sleeve rod) and a clamping plate 1003. The telescopic sleeve 1001 is arranged on the inner side wall of the slave support frame 902, and the spring 1002 is arranged inside the telescopic sleeve 1001. The arrangement of the spring 1002 allows the sleeve rod to be popped out along the sleeve in the absence of external force.

[0047] The movable end surface of the telescopic sleeve 1001 is connected to the clamping plate 1003, and the two clamping plates 1003 are clamped at the connection between the secondary pipe 3 and the connecting plug 2. The clamping plates 1003 are squeezed first, and then released when the clamping plates 1003 can be clamped on both sides of the connection between the secondary pipe 3 and the connecting plug 2. At this time, under the action of the spring 1002, the clamping plates 1003 can be clamped on both sides of the connection between the secondary pipe 3 and the connecting plug 2.

[0048] Working principle: Before use, first connect the connecting plug 2 and the main pipeline, then place the supporting frame 9 under the connecting plug 2 and the slave pipeline 3, and after they are placed, insert the slave pipeline 3 into the connecting plug 2.

[0049] After insertion, turn the handle 404, which can drive the transmission rod 403 to rotate. Since the screw 401 and the transmission rod 403 are connected through the bevel gear set 402, the screw 401 can be driven to rotate. When the screw 401 rotates, it can adapt to the threaded hole 5, so that the slave pipe 3 moves closer to one side of the connecting plug 2 and squeezes the rubber to achieve the effect of connecting the slave pipe 3 and the connecting plug 2 to each other.

[0050] Then squeeze the clamping plate 1003, and release it when the clamping plate 1003 can be clamped on both sides of the connection between the secondary pipe 3 and the connecting plug 2. At this time, under the action of the spring 1002, the clamping plate 1003 can be clamped on both sides of the connection between the secondary pipe 3 and the connecting plug 2.
