Description

Technical Field

[0001] The present application relates to the field of circuit connection, and in particular to an extension cord for a water leakage monitoring and protection device for a waterway. Background Art

[0002] In the existing water pipe leakage monitoring and protection device, when the manufacturer produces it, in order to save costs, the wire of the water pipe leakage monitoring and protection device is produced to be relatively short. During actual use, when the water pipe leakage monitoring and protection device is slightly far from the solenoid valve, the length of the wire of the water pipe leakage monitoring and protection device is insufficient, which will cause a lot of trouble during use, and thus greatly reduce the utilization rate of the water pipe leakage monitoring and protection device.

[0003] Chinese Patent with Publication No. CN107293919A discloses a power extension cord. One end of the power extension cord is provided with a power plug, and the other end is provided with a power socket. When the length of the power cord we usually use is insufficient, one end of the extension cord can be plugged into the socket interface, and the power cord can be inserted into the other end for use, avoiding the trouble caused by the insufficient length of the power cord.

[0004] Regarding the above related technology, the inventor believes that the length of the power cord of the power extension cord of this invention patent is fixed. When the water pipe leakage detection and protection device is used in different scenarios, it is necessary to replace the power extension cord with different total lengths according to different distances, which is rather inconvenient. Utility Model Content

[0005] In order to facilitate the adjustment of the length of the power cord of the water pipe leakage detection and protection device, the present application provides an extension cord for a water leakage monitoring and protection device for a waterway.

The housing is provided with an inlet hole and an outlet hole for the power cord to pass through.

[0008] By adopting the above technical solution, when the water pipe leakage detection and protection device is in use, since the power cord is not long enough, an extension cord is usually needed for auxiliary use. The length of the power cord of the traditional extension cord is usually fixed, which is inconvenient to use. The extension cord for the water pipe leakage detection and protection device provided by the present application includes a power cord and a reel. When in use, open the housing, adjust the power cord to an appropriate length, and then wind the excess power cord around the spool, making the adjustment of the length of the power cord during the use of the water pipe leakage detection and protection device simpler and more convenient.

Detailed implementation manners

[0033] The following further elaborates on this application Figure 1-6 in conjunction with the attached drawings.

[0034] The embodiment of this application discloses an extension cord of a water leakage monitoring and protection device for a waterway. Refer to Figure 1 and Figure 2 , the extension cord of the water leakage monitoring and protection device for a waterway includes a power cord 1 and a wire reel 2. The wire reel 2 includes a housing 21 and a wire reel 22 disposed inside the housing 21. The wire reel 22 is rotatably and slidably disposed with respect to the housing 21, and the power cord 1 is wound around the wire reel 22.

[0035] Refer to Figure 2 and 3 , the housing 21 includes an upper housing 211 and a lower housing 212, and the upper housing 211 is clamped to the lower housing 212. The upper housing 211 is provided with an installation groove 213 for installing the wire reel 22. The upper housing 211 is provided with an inlet hole 214 and an outlet hole 215 for the power cord 1 to enter and exit on the side wall of the installation groove 213. Both the inlet hole 214 and the outlet hole 215 penetrate through the side of the upper housing 211 close to the lower housing 212.

[0036] A clamping block 216 is provided on one side of the lower shell 212 close to the upper shell 211. The clamping block 216 includes a horizontal portion 2162 and a vertical portion 2161. One end of the vertical portion 2161 is integrally formed with the lower shell 212, and one end of the vertical portion 2161 away from the lower shell 212 is vertically connected to the horizontal portion 2162. The horizontal portion 2162 and the vertical portion 2161 are connected in an integrally formed manner. A clamping slot 217 for clamping the horizontal portion 2162 is provided on the inner wall of the mounting groove 213 of the upper shell 211. The clamping of the clamping block 216 and the clamping slot 217 makes the connection between the upper shell 211 and the lower shell 212 simple and convenient. The clamping block 216 is provided with a deformation groove 218. Through the provision of the deformation groove 218, it is easier for the clamping block 216 to be inserted into the clamping slot 217 and to release the clamping relationship with the clamping slot 217. A force-applying groove 2111 is provided on the outer periphery of the upper shell 211 . The force-applying groove 2111 provides a force-applying position for the staff to open the shell 21 , thereby making it easier to open the shell 21 .

[0037] The lower housing 212 is provided with a positioning block 219 at a position corresponding to the wire inlet hole 214, and the positioning block 219 is inserted into the wire inlet hole 214. By providing the positioning block 219, the size of the wire inlet hole 214 is reduced, so that the wire inlet hole 214 can be more matched with the diameter of the power cord 1, and the shaking of the power cord 1 in the wire inlet hole 214 is reduced. In this embodiment, the positioning block 219 is integrally formed with the lower housing 212.

[0038] Reference Figure 4 The upper shell 211 is provided with a rotating shaft 23 at the bottom wall of the mounting groove 213, and the cable reel 22 is provided with a through hole 24 for the rotating shaft 23 to pass through. The rotating shaft 23 includes a connecting shaft 231 connected to the upper shell 211 and a sliding shaft 232 slidably arranged with the connecting shaft 231. In this embodiment, the connecting shaft 231 is provided with a sliding groove 233 for the sliding shaft 232 to slide, and the sliding shaft 232 is inserted into the connecting shaft 231. In other embodiments, the sliding groove 233 may be provided in the sliding shaft 232, and the connecting shaft 231 may be inserted into the sliding groove 233.

[0039] In this embodiment, the connecting shaft 231 and the upper shell 211 are connected by thermal welding.

A limit groove 235 for inserting the limit block 234 is provided on the inner wall of the sliding groove 233 of the connecting shaft 231. The limit block 234 cooperates with the limit groove 235 to limit the sliding shaft 232, thereby reducing the probability of the sliding shaft 232 slipping out of the connecting shaft 231.

[0041] When installing the sliding shaft 232 and the connecting shaft 231, first insert one end of the sliding shaft 232 away from the limit block 234 into the connecting shaft 231, and then connect the connecting shaft 231 and the upper housing 211 by thermal welding.

[0042] The rotating shaft 23 further includes a limit cap 236. The limit cap 236 is snap-connected to one end of the sliding shaft 232 away from the connecting shaft 231, and the diameter of the limit cap 236 is greater than the diameter of the through hole 24. Through the setting of the limit cap 236, the limit for the wire reel 22 is provided, thereby reducing the probability of the wire reel 22 sliding out of the rotating shaft 23.

[0043] Refer to Figure 5 and Figure 6 As shown in, a positioning member 237 protrudes from one side of the limit cap 236 close to the sliding shaft 232. The positioning member 237 includes a connecting portion 2371 connected to the limit cap 236 and a clamping portion 2372 provided on the side of the connecting portion 2371 away from the limit cap 236. The clamping portion 2372 is arranged around the outer periphery of the connecting portion 2371, and the sliding shaft 232 is provided with a groove 238 for the positioning member 237 to be clamped. In this embodiment, the connecting portion 2371 and the clamping portion 2372 as well as the connecting portion 2371 and the limit cap 236 are integrally formed.

[0044] The implementation principle of the extension cord of the water leakage monitoring protector in the embodiment of the present application is as follows: The extension cord of the water leakage monitoring protector provided in the present application includes a power cord 1 and a wire reel 2.
