[0037] The following is combined with Figure 1 - Figure 2 This application is described in further detail.

[0038] The embodiment of the present application discloses a rod connection mechanism 100 .

[0039] Reference Figure 1 - Figure 2 According to the embodiment of the present application, the rod connection mechanism 100 comprises: a connection assembly 10 and a locking member 40. The connection assembly 10 comprises a first connection member 101 and a second connection member 102. The first connection member 101 is plugged into the second connection member 102. Specifically, along the height direction of the rod connection mechanism 100, the height direction of the rod connection mechanism 100 can refer to Figure 2 In the up-down direction, the lower end of the first connecting member 101 is inserted into the upper end of the second connecting member 102, and the first connecting member 101 and the second connecting member 102 are coaxially arranged.

[0040] The upper end of the first connecting member 101 is suitable for connecting with the first rod 20, and the lower end of the second connecting member 102 is suitable for connecting with the second rod 30. The outer peripheral wall of the first connecting member 101 near the lower end has a first limiting portion 1011, and the upper end of the second connecting member 102 has a first connecting portion 1021. The locking member 40 is sleeved on the outer side of the first connecting member 101, and the locking member 40 is suitable for approaching or moving away from the second connecting member 101 along the first connecting member 101. 2 movement, the locking member 40 has a limiting groove 401, the limiting groove 401 is open toward the second connecting member 102, the inner bottom wall of the limiting groove 401 is stopped against the first limiting portion 1011, the inner peripheral wall of the limiting groove 401 close to the second connecting member 102 is provided with the second connecting portion 4011, the first connecting portion 1021 extends into the limiting groove 401 and is connected and matched with the second connecting portion 4011, and the locking member 40 is used to lock the first connecting member 101 to the second connecting member 102.

[0041] Specifically, the locking member 40 is first sleeved on the outer side of the first connecting member 101, and then the first connecting member 101 and the first rod 20 are connected and matched, and the second connecting member 102 and the second rod 30 are connected and matched, and then the first connecting member 101 is inserted into the second connecting member 102 to keep the first connecting member 101 in a fixed position relative to the second connecting member 102, and then the locking member 40 moves close to the second connecting member 102, the inner bottom wall of the limiting groove 401 is stopped by the first limiting portion 1011, and the second connecting portion 4011 and the first connecting portion 1021 are connected and matched, so that the first connecting member 101 can be locked to the second connecting member 102, and then the technical effect of connecting the first rod 20 and the second rod 30 together through the rod connecting mechanism 100 can be achieved, and in the process of connecting the first rod 20 and the second rod 30 together, such a setting can also try to avoid one of the first rod 20 and the second rod 30 from rotating relative to the other.

[0042] When the first connecting member 101 and the second connecting member 102 need to be unlocked, the operator releases the connection between the first connecting portion 1021 and the second connecting portion 4011 and drives the locking member 40 to move away from the second connecting member 102, thereby unlocking the first connecting member 101 and the second connecting member 102.

[0043] Further, the first connecting member 101 and the second connecting member 102 define a conveying channel 1012. Along the height direction of the rod connecting mechanism 100, the conveying channel 1012 penetrates through the first connecting member 101 and the second connecting member 102, and the conveying channel 1012 is communicated with both the first rod 20 and the second rod 30. The conveying channel 1012 is used for conveying liquid, and the central axis of the conveying channel 1012 can coincide with the central axis of the first connecting member 101, the central axis of the first rod 20, and the central axis of the second rod 30.

[0044] In some specific embodiments, a first avoidance hole is provided on the lower end wall of the first rod 20, and the first avoidance hole penetrates through the first rod 20. A second avoidance hole is provided on the upper end wall of the second rod 30, and the second avoidance hole penetrates through the second rod 30. That is to say, both the first rod 20 and the second rod 30 are configured as hollow rods. A liquid suction device is provided at one end of the second rod 30 away from the rod connecting mechanism 100, and the liquid suction device is communicated with the second avoidance hole. The conveying channel 1012 is communicated with both the first avoidance hole and the second avoidance hole. After the first rod 20, the rod connecting mechanism 100, and the second rod 30 are assembled to form a rod device, a hole position connected to the ground is opened on the ground. When there is liquid underground, one end of the second rod 30 provided with the liquid suction device extends into the hole and moves away from the ground along the hole position. When the liquid suction device is in full contact with the liquid underground, the staff starts the liquid suction device through a switch to suck the liquid underground to the ground, and the liquid underground flows out to the ground through the rod device.

[0045] Further, one first rod 20, one rod connecting mechanism 100, and one second rod 30 are configured as a rod device. The water stop device may include at least one rod device. When there are multiple rod devices, the multiple rod devices are arranged in sequence along the height direction of the rod connecting mechanism 100, and the second rod 30 of one rod unit in any two adjacent rod units is connected and matched with the first connecting member 101 of the other rod unit. It should be noted that the second rod 30 of the rod unit located at the lowermost end among the multiple rod devices is provided with a liquid suction device, and the multiple rod devices can move closer to or away from the ground simultaneously.

[0046] Thus, the first connecting member 101 is locked to the second connecting member 102 by the locking member 40, so that the first rod member 20 is kept in a fixed position relative to the second rod member 30. Compared with the prior art, it is not necessary for one of the first rod member 20 and the second rod member 30 to rotate relative to the other to achieve the connection and cooperation between the first rod member 20 and the second rod member 30, which can prevent the wire body outside the first rod member 20 and / or the wire body outside the second rod member 30 from being wound around the first rod member 20 and / or the second rod member 30 as much as possible, thereby reducing the disassembly difficulty of the first rod member 20 and the second rod member 30, and further improving the disassembly efficiency of the first rod member 20 and the second rod member 30.

[0047] Referring to Figure 2 , in some embodiments of the present application, an external thread is provided on the outer peripheral wall of the first connecting portion 1021, and an internal thread is correspondingly provided on the inner peripheral wall of the second connecting portion 4011. The first connecting portion 1021 and the second connecting portion 4011 are threadedly connected. During the process of the second rod member 30 moving away from the ground, through the threaded connection between the first connecting portion 1021 and the second connecting portion 4011, the locking member 40 and the second connecting member 102 can be prevented from separating as much as possible, the first rod member 20 and the second rod member 30 can be prevented from separating, and further the connection reliability between the locking member 40 and the second connecting member 102 can be improved.

[0048] Referring to Figure 2 , in some embodiments of the present application, a second limiting portion 1022 is provided on the outer peripheral wall of the second connecting member 102, and the second limiting portion 1022 abuts against the locking member 40. Specifically, the second limiting portion 1022 is located below the first connecting portion 1021. When the first connecting portion 1021 extends into the limiting groove 401 and is connected and cooperated with the second connecting portion 4011, the second limiting portion 1022 abuts against the lower end wall of the locking member 40. The operator can judge whether the second connecting portion 4011 extends into the preset position in the limiting groove 401 by observing whether the locking member 40 abuts against the second limiting portion 1022, so as to avoid the separation of the locking member 40 and the second connecting member 102 caused by the second connecting portion 4011 not extending into the preset position in the limiting groove 401, and further improve the connection reliability between the locking member 40 and the second connecting member 102.

[0049] Furthermore, a second sealing member can be provided between the second limiting portion 1022 and the locking member 40. When the second rod member 30 moves away from the ground, by providing a second sealing member between the second limiting portion 1022 and the locking member 40, the liquid outside the locking member 40 can be prevented from flowing into the limiting groove 401 as much as possible, thereby reducing the number of times the operator cleans the limiting groove 401, and further improving the use experience of the rod connection mechanism 100.

[0050] Referring to Figure 2, in some embodiments of the present application, a plug-in portion 1013 is provided at one end of the first connecting member 101 close to the second connecting member 102, and an avoidance groove 1023 is provided at the end of the second connecting member 102 close to the first connecting member 101. The plug-in portion 1013 and the avoidance groove 1023 are arranged opposite to each other. The plug-in portion 1013 is adapted to extend into or out of the avoidance groove 1023, and the plug-in portion 1013 is adapted to be connected and cooperate with the avoidance groove 1023 so that the first connecting member 101 is kept in a fixed position relative to the second connecting member 102.

[0051] Specifically, during the process of connecting the first rod member 20 and the second rod member 30 by the rod member connecting mechanism 100, by inserting the plug-in portion 1013 of the first connecting member 101 into the avoidance groove 1023 of the second connecting member 102, the first connecting member 101 and the second connecting member 102 can be kept relatively fixed. Then, the locking member 40 is driven to move close to the second connecting member 102 so that the first connecting portion 1021 and the second connecting portion 4011 are engaged. Compared with directly locking the first connecting member 101 to the second connecting member 102 by the locking member 40, such a setting can reduce the difficulty of locking the first connecting member 101 to the second connecting member 102 by the locking member 40, thereby improving the assembly efficiency of the rod member connecting mechanism 100.

[0052] Furthermore, the shape of the plug-in portion 1013 and the shape of the avoidance groove 1023 can both be configured as rectangles. When assembling the rod member connecting mechanism 100, by inserting the plug-in portion 1013 into the avoidance groove 1023, the rotation of the first rod member 20 relative to the second rod member 30 can be avoided as much as possible, thereby preventing the wire body outside the first rod member 20 and / or the wire body outside the second rod member 30 from winding around the first rod member 20 and / or the second rod member 30 as much as possible, and further improving the assembly efficiency of the rod member connecting mechanism 100.

[0053] Referring to Figure 2 , in some embodiments of the present application, the connecting assembly 10 may further include a bearing 103. The bearing 103 is arranged in the limiting groove 401. One end of the bearing 103 abuts against the first limiting portion 1011, and the other end abuts against the first connecting portion 1021. Specifically, along the height direction of the rod member connecting mechanism 100, the upper end wall of the bearing 103 abuts against the lower end wall of the first limiting portion 1011, and the lower end wall of the bearing 103 abuts against the upper end wall of the first connecting portion 1021, thereby achieving the technical effect of limiting the bearing 103 between the first connecting member 101 and the second connecting member 102.

[0054] Moreover, the bearing 103 is disposed between the inner peripheral wall of the limiting groove 401 and the insertion portion 1013. Specifically, the inner peripheral wall of the bearing 103 is in abutting fit with the outer peripheral wall of the insertion portion 1013, and the outer peripheral wall of the bearing 103 is in abutting fit with the inner peripheral wall of the limiting groove 401. Such an arrangement can achieve the technical effect of limiting the bearing 103 between the locking member 40 and the insertion portion 1013.

[0055] By providing the bearing 103 in the limiting groove 401 and the inner peripheral wall of the bearing 103 abutting against the outer peripheral wall of the insertion portion 1013, when the insertion portion 1013 moves away from or close to the avoidance groove 1023, the bearing 103 can lubricate the insertion portion 1013, thereby reducing the wear amount of the insertion portion 1013, and further improving the service life of the first connecting member 101. In some specific embodiments, the bearing 103 can be a sliding bearing 103.

[0056] Furthermore, lubricating oil can also be provided between the lower end wall of the bearing 103 and the upper end wall of the first connecting portion 1021. There is brine underground, and during the process of the second rod member 30 moving away from the ground, a small amount of brine will enter the limiting groove 401. The brine will corrode the bearing 103, making it difficult for the bearing 103 to separate from the first connecting portion 1021. By providing lubricating oil between the bearing 103 and the first connecting portion 1021, the lubricating oil can lubricate the bearing 103, thereby reducing the difficulty of separating the bearing 103 from the first connecting portion 1021, and further improving the disassembly efficiency of the bearing 103.

[0057] Furthermore, lubricating oil can also be provided between the upper end wall of the bearing 103 and the first limiting portion 1011.

[0058] Refer to Figure 2, in some embodiments of the present application, the connecting component 10 may further include a first seal 104. A receiving groove 1014 is provided on the end wall of the first connecting member 101 close to the second connecting member 102. Specifically, along the height direction of the rod connecting mechanism 100, the receiving groove 1014 is provided on the lower end wall of the insertion portion 1013. The first seal 104 is disposed in the receiving groove 1014, and the lower end wall of the first seal 104 is adapted to abut against the second connecting member 102. Specifically, when the insertion portion 1013 extends into the avoidance groove 1023, the lower end wall of the first seal 104 abuts against the bottom wall of the avoidance groove 1023. The first seal 104 is used to seal the insertion portion 1013 and the avoidance groove 1023. When the liquid suction device starts to work and sucks the liquid into the delivery channel 1012, by using the first seal 104 to seal the insertion portion 1013 and the avoidance groove 1023, it is possible to avoid as much as possible the liquid in the delivery channel 1012 from flowing into the limit groove 401, thereby preventing the liquid from corroding the bearing 103 as much as possible, and further extending the service life of the bearing 103. Moreover, the first seal 104 can also avoid as much as possible the liquid in the delivery channel 1012 from flowing out of the delivery channel 1012, resulting in a decrease in the water pressure in the delivery channel 1012, thereby avoiding the inability to transport the liquid underground to the ground, and further improving the working reliability of the rod connecting mechanism 100.

[0059] In some specific embodiments, the first seal 104 may be a rubber sealing ring, but the present application is not limited thereto, and the first seal 104 may also be a gasket.

[0060] Referring to Figure 2 , in some embodiments of the present application, a connecting groove 1015 is provided at the end of the first connecting member 101 away from the second connecting member 102, and the connecting groove 1015 is in communication with both the delivery channel 1012 and the first avoidance hole of the first rod 20. The first rod 20 is adapted to extend into or out of the connecting groove 1015, and the connecting groove 1015 is connected and cooperated with the first rod 20.

[0061] Specifically, one end of the first rod 20 close to the first connecting member 101 extends into the connecting groove 1015 and is connected and cooperated with the connecting groove 1015, thereby achieving the technical effect of connecting the first rod 20 and the first connecting member 101 together. Along the height direction of the rod connecting mechanism 100, when one end of the first rod 20 close to the first connecting member 101 extends into the connecting groove 1015, the connecting groove 1015 can limit the first rod 20, thereby avoiding the first rod 20 from deviating from the preset position as much as possible, reducing the connection difficulty between the first rod 20 and the first connecting member 101, and thus improving the assembly efficiency of the first rod 20 and the first connecting member 101.

[0062] When the first rod 20 needs to be separated from the first connecting member 101, one end of the first rod 20 close to the first connecting member 101 is moved out of the connecting groove 1015, so that the first rod 20 and the first connecting member 101 are separated.

[0063] Furthermore, after the first rod 20 and the first connecting member 101 are connected together, the liquid in the conveying channel 1012 flows into the first avoidance hole of the first rod 20 through the connecting groove 1015, and then flows out to the ground through the first avoidance hole of the first rod 20, so that the technical effect of conveying the liquid in the conveying channel 1012 to the ground can be achieved.

[0064] Refer to Figure 2 , in some embodiments of the present application, the inner peripheral wall of the connecting groove 1015 is configured as an inclined surface, and an internal thread is provided on the inner peripheral wall of the connecting groove 1015. The internal thread of the connecting groove 1015 is adapted to be connected and matched with the external thread of the first rod 20. Specifically, the outer peripheral wall of the end of the first rod 20 close to the first connecting member 101 is configured as an inclined surface and is provided with an external thread, and the slope of the inner peripheral wall of the connecting groove 1015 is equal to the slope of the outer peripheral wall of the end of the first rod 20 close to the first connecting member 101. When the end of the first rod 20 close to the first connecting member 101 extends into the connecting groove 1015, the inner peripheral wall of the connecting groove 1015 can guide the first rod 20, thereby reducing the connection difficulty between the first rod 20 and the first connecting member 101, and further improving the assembly efficiency of the first rod 20 and the first connecting member 101.

[0065] Refer to Figure 2 , in some embodiments of the present application, a third connecting portion 1024 is provided at the end of the second connecting member 102 away from the first connecting member 101. The third connecting portion 1024 is adapted to extend into or out of the second rod 30, and the third connecting portion 1024 is connected and matched with the second rod 30. Specifically, a connecting hole is provided at one end of the second rod 30 close to the second connecting member 102, and the third connecting portion 1024 extends into the connecting hole of the second rod 30 and is connected and matched with the connecting hole, so that the technical effect of connecting the second rod 30 and the second connecting member 102 together can be achieved. And along the height direction of the rod connecting mechanism 100, when the third connecting portion 1024 extends into the connecting hole of the second rod 30, the third connecting portion 1024 can limit the second rod 30, so as to avoid the second rod 30 deviating from the preset position as much as possible, reduce the connection difficulty between the second rod 30 and the second connecting member 102, and further improve the assembly efficiency of the second rod 30 and the second connecting member 102.

[0066] Refer to Figure 2, in some embodiments of the present application, the outer peripheral wall of the third connecting portion 1024 is configured as an inclined surface, and an external thread is provided on the outer peripheral wall of the third connecting portion 1024. The external thread on the outer peripheral wall of the third connecting portion 1024 is adapted to be connected and mated with the internal thread of the second rod member 30. Specifically, the inner peripheral wall of the connecting hole of the second rod member 30 is configured as an inclined surface and is provided with an internal thread, and the slope of the inner peripheral wall of the connecting hole of the second rod member 30 is equal to the slope of the outer peripheral wall of the third connecting portion 1024. When the third connecting portion 1024 extends into the connecting hole of the second rod member 30, the outer peripheral wall of the third connecting portion 1024 can guide the second rod member 30, thereby reducing the connection difficulty between the second rod member 30 and the second connecting member 102, and further improving the assembly efficiency of the second rod member 30 and the second connecting member 102.

[0067] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
