Embodiment

[0028] Please refer to Figures 1 - 9 , the present utility model provides a technical solution: an electric extra-long dog leash, including a storage structure 100 and a traction winding structure 200.

[0029] Please refer to Figures 1 - 5 , the storage structure 100 includes a lower housing 110 and an upper housing 120. The lower housing 110 and the upper housing 120 are fixedly installed by screws, and a holding handle 130 is formed at the upper ends of the lower housing 110 and the upper housing 120.

[0030] An electric motor positioning groove 111 and a storage battery positioning groove 112 are formed inside the lower housing 110. The servo motor 210 is placed inside the electric motor positioning groove 111. A first card slot 131 is formed inside the holding handle 130. A sliding groove 132 is opened above the first card slot 131. A second card slot 140 is also formed inside the holding handle 130. A positioning through slot 150 is formed on one side of the lower housing 110.

[0031] Please refer to Figure 1 、 Figure 2 、 Figures 6 - 9 , the traction winding structure 200 includes a servo motor 210, a control member 220, a cover plate 230 and a traction webbing 250. The servo motor 210 and the control member 220 are both installed inside the lower housing 110. The control member 220 is electrically connected to the servo motor 210. An end of the output shaft of the servo motor 210 is installed with a central shaft rod 211. Flattened grooves 212 are formed on both sides of the central shaft rod 211. A round hole 231 is opened inside the cover plate 230. The round hole 231 is sleeved on the central shaft rod 211. The cover plate 230 is installed inside the lower housing 110 by screws and is located on one side of the servo motor 210. A disc 240 is sleeved on the central shaft rod 211. A traction webbing 250 is installed on the disc 240. Here, the other end of the traction webbing 250 is installed with a hook for connecting with a dog's collar. At the same time, the traction webbing 250 has a length of more than fifteen meters.

[0032] The control member 220 includes a storage battery 221, a toggle switch 223 and a push button 224. The storage battery 221 is placed in the storage battery positioning groove 112. The storage battery 221 is electrically connected with a circuit board 222 through a connecting wire. The circuit board 222 is snap-fitted in the second card slot 140. The toggle switch 223 is placed in the first card slot 131. The push button 224 is slidably connected in the sliding groove 132. The push button 224 is snap-fitted on the toggle switch 223. Here, the toggle switch 223 has three gears: forward, lock and reverse. When the push button 224 is toggled forward, the toggle switch 223 is driven into the forward gear, and the servo motor 210 rotates forward to drive the disc 240 to rotate, so that the traction webbing 250 is stretched outwards. When the push button 224 is toggled backward, the toggle switch 223 is driven into the reverse gear, and the servo motor 210 rotates in reverse and drives the disc 240 to rotate accordingly, to wind up the traction webbing 250. When the push button 224 is in the middle gear, the servo motor 210 is locked, and the traction webbing 250 cannot be wound up or pulled out.

[0033] A protrusion 2231 is formed on the toggle switch 223. A buckle 2241 that matches the chute 132 is fixed to the bottom of the push button 224. The buckle 2241 is snapped onto the chute 132. A groove 2242 that matches the protrusion 2231 is formed at the bottom of the buckle 2241, and the groove 2242 is snapped onto the protrusion 2231. A charging interface 2221 and a charging indicator light 2222 are also electrically installed on the circuit board 222. Both the charging interface 2221 and the charging indicator light 2222 penetrate through the holding handle 130 and extend to the outside. Here, the charging indicator light 2222 can remind of the remaining power of the storage battery 221, and the charging interface 2221 is used to charge the storage battery 221.

[0034] A C-shaped groove 241 is formed on one side of the disc 240. A ring 251 is sewn at one end of the traction webbing 250. The ring 251 is sleeved on the C-shaped groove 241. An offset hole 242 is also formed at the center position of the disc 240. The central shaft rod 211 is inserted into the interior of the offset hole 242. Here, the central shaft rod 211 is flat and is set to match the offset hole 242, so that the disc 240 can be driven to rotate by the rotation of the central shaft rod 211. The other end of the traction webbing 250 is slidably sleeved with a webbing sleeve 252, and the webbing sleeve 252 is installed in the positioning through groove 150, so that the webbing sleeve 252 can make the telescoping of the traction webbing 250 more stable and smooth.

[0035] Specifically, the working principle of this electric extra-long dog leash: When in use, connect the hook on the traction webbing 250 to the dog's collar. Then, hold the dog leash through the holding handle 130. When pulling the dog, when the push button 224 is toggled forward, the toggle switch 223 is driven into the forward gear, and the servo motor 210 rotates forward to drive the disc 240 to rotate, so that the traction webbing 250 is stretched out under the pulling of the dog; when the push button 224 is toggled backward, the toggle switch 223 is driven into the reverse gear, and the servo motor 210 rotates in reverse and drives the disc 240 to rotate accordingly to wind up the traction webbing 250; when the push button 224 is in the middle gear, the servo motor 210 is locked, and the traction webbing 250 cannot be wound up or pulled out. Such an extra-long dog leash can be conveniently retracted and extended electrically, which is more conducive to meeting the usage needs of different dog walkers and has a wider range of use and is more applicable and convenient.

[0036] It should be noted that the specific model specifications of the servo motor 210 and the storage battery 221 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0037] The power supply and principle of the servo motor 210 and the storage battery 221 are clear to those skilled in the art and will not be described in detail here.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
