[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] An embodiment of the present application provides a single-head cable for a remote water meter, which can solve the problem that single-head cables in related technologies are prone to mechanical damage.

[0032] See also Figures 1 to 4 , a single-head cable for a remote water meter, comprising:

[0033] Universal tube 1, closed tube 2, universal tube 1 includes outlet tube 11, outlet tube 11 has a first protection space for placing protected cables, closed tube 2 includes: tube body 21, closing plate 22, tube body 21 has openings at both ends, tube body 21 is slidably connected to outlet tube 11, tube body 21 has a second protection space for placing unprotected cables, and the first protection space is connected to the second protection space, closing plate 22 is detachably connected to one side opening of tube body 21, closing tube 2;

[0034] The universal tube 1 also includes a tube body 12 and a connecting piece 13;

[0035] The outlet tube 11 is connected to one end of the tube body 12, and the other end of the tube body 12 is connected to the connecting piece 13;

[0036] In this application, one end of the pipe body 12 is connected to the remote water meter through a connector 13, and the other end of the pipe body 12 is installed with an outlet tube 11. Figure 2 As shown, the closing cylinder 2 is connected to the outlet cylinder 11, and the closing cylinder 2 closes the outlet cylinder 11 and wraps the cable body through the cylinder body 21 to prevent the cable body from being directly exposed to the outside world, which would cause mechanical damage to the cable body when not in use. The cable body is further protected by the closing plate 22 to prevent the cable body from excessive contact with dust.

[0037] The outlet tube 11 is provided with a chute 3, and the tube body 21 is connected with a slider 4, which is slidably connected in the chute 3;

[0038] The slide groove 3 is opened along the length direction of the outlet tube 11. When the slider 4 slides in the slide groove 3, the barrel 21 will slide along the length direction of the outlet tube 11. Before the present application is used, the closing plate 22 is installed at one end of the barrel 21, so that the closing plate 22, the barrel 21, the outlet tube 11 and the tube body 12 form a closed environment to protect the cable body. When it is needed, the closing plate 22 is first removed from the barrel 21, and then the barrel 21 is slid on the outlet tube 11 to expose the cable body for easy operation by the staff.

[0039] Also includes a first spring 5;

[0040] The two ends of the first spring 5 are connected to the barrel 21 and the outlet barrel 11 respectively;

[0041] like Figure 2 As shown, the first spring 5 will continue to apply force to the barrel 21 in the direction away from the outlet barrel 11, so that the barrel 21 always remains extended on the outlet barrel 11 when there is no external force, thereby preventing the barrel 21 from sliding on the outlet barrel 11, causing the closing plate 22 to squeeze the cable body.

[0042] The present application also includes a limiting structure, which includes a plug-in 23 and a slot 24;

[0043] The plug-in 23 is slidably connected to the outlet tube 11 , and the moving direction of the plug-in 23 is perpendicular to the moving direction of the tube body 21 . The plug-in 23 can be inserted into the slot 24 .

[0044] The limiting structure further includes a second spring 25, the two ends of which are respectively connected to the plug-in 23 and the outlet tube 11;

[0045] A groove with an opening direction perpendicular to the length direction of the outlet tube 11 is provided on the outlet tube 11, and a second spring 25 and a plug-in 23 are arranged in the groove. The second spring 25 will continuously provide force to the plug-in 23 to extend out of the groove. The slot 24 is provided on the barrel body 21. When this application is not in use, the barrel body 21 will squeeze the plug-in 23, so that the plug-in shrinks in the groove. When this application needs to be used, the barrel body 21 slides, and when the slot 24 moves to above the plug-in 23, the plug-in 23 receives the thrust of the second spring 25 and is inserted into the slot 24, thereby fixing the position of the barrel body 21 on the outlet tube 11 to avoid the barrel body 21 from rebounding due to the thrust of the first spring 5, which makes it inconvenient for the staff to operate.

[0046] It also includes a fixing member 6, a fixing groove 7, and a through hole 8;

[0047] The fixing member 6 can pass through the through hole 8, and the fixing member 6 can be inserted into the fixing groove 7;

[0048] Also includes a third spring 9;

[0049] The two ends of the third spring 9 are respectively connected to the fixing member 6 and the closing plate 22, and the fixing member 6 is slidably connected in the through hole 8;

[0050] like Figure 4 As shown, the fixing member 6 is slidably connected to the through-hole 8, and the two ends of the third spring 9 are respectively connected to the fixing member 6 and the side of the through-hole 8, so that the third spring 9 will continuously output a force to the fixing member 6 to push the fixing member 6 out of the through-hole 8. Therefore, when the fixing member 6 is pushed out of the through-hole 8 and inserted into the fixing groove 7 on the outlet tube 11, if no staff pulls out the fixing member 6, the third spring 9 will continue to output a force to the fixing member 6, so that the fixing member 6 will always be inserted into the fixing groove 7. Moreover, since the other end of the closing plate 22 is rotatably connected to the cylinder body 21, the closing plate 22 is prevented from moving.

[0051] It should be pointed out that before the staff uses this application, they need to first pull out the fixing part 6 from the fixing groove 7, then rotate the closing plate 22 so that the closing plate 22 no longer blocks the barrel 21, and then move the barrel 21 to expose the cable body to the outside world for operation.

[0052] Here's how this application works:

[0053] When the present application is not in use, the barrel body 21 is located on a side away from the outlet barrel 11, and at this time the fixing member 6 is inserted into the fixing groove 7, and the closing plate 22 closes one side of the barrel body 21 to protect the cable body therein;

[0054] When the present application is needed, first pull the fixing part 6 out of the fixing slot 7, then rotate the closing plate 22 so that it no longer blocks the barrel 21, and then move the barrel 21 so that the plug-in 23 is inserted into the slot 24, fixing the position of the barrel 21, making it convenient for the staff to operate and connect the cable body.
