[0003] The existing portable power grid detection equipment (Announcement No.: CN219625535U) has the following defects: the above-mentioned device winds the connecting wire around the surface of the coil spring and connects the connecting wire to the outer end of the coil spring, but in actual use, the other end of the connecting wire needs to be connected to the power quality detector, that is, the other end of the connecting wire is fixed, so when one end of the connecting wire is pulled, the coil spring will rotate, and the other end of the connecting wire will also extend outward, and accumulate inside the installation frame and cause friction with the inner wall of the installation frame, causing wear of the connecting wire. At the same time, the elastic force of the coil spring will cause tension on the connecting wire, making the connection between the crocodile clip and the device unreliable. For this reason, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to the attached Figure 1 -Attached Figure 4 A State Grid comprehensive function detection device comprises a detector body 1, a wire-receiving assembly is arranged on the top surface of the detector body 1, and the wire-receiving assembly comprises two rebound boxes 2 arranged above the detector body 1, and a winding roller 201 is rotatably connected inside the rebound box 2, and the winding roller 201 is a hollow structure. A coil spring 202 is arranged inside the rebound box 2, and the two ends of the coil spring 202 are respectively fixed to the inside of the rebound box 2 and the outer wall of the winding roller 201, and a detection line 203 is arranged on the outer wall of the winding roller 201. An alligator clip is fixed to one end of the detection line 203 away from the detector body 1, and a plug is fixed to the other end. Connection boxes 204 are fixed on the front and rear sides of the rebound box 2, and the two ends of the winding roller 201 extend to one side of the inside of the two connection boxes 204, and are rotatably connected to one side of the inside of the connection box 204.

[0022] In the embodiment, the outer wall of the connection box 204 is provided with an extension hole 205, and the outer wall of the winding roller 201 is provided with two fixing holes 206. One end of the detection line 203 passes through the extension hole 205 of the connection box 204 at the rear side of the rebound box 2, then passes through the fixing hole 206 near the rear end of the winding roller 201 and is merged into the interior of the winding roller 201, then passes through the fixing hole 206 near the front end of the winding roller 201, and then passes through the extension hole 205 of the connection box 204 at the front side of the rebound box 2. The wall and the inside of the fixing hole 206 are fixed with glue. By winding the detection line 203 on the movable winding roller 201, when the detection line 203 is pulled, the winding roller 201 will move laterally and make the detection line 203 wound thereon extend in two directions, so that it can be adjusted according to the working environment. This winding structure can effectively prevent one end of the detection line 203 from being pulled and extended while the other end is extended inside the winding mechanism, and rotates inside the winding mechanism, causing damage to the detection line 203.

[0023] In the embodiment, the front end of the winding roller 201 also extends through and extends to the front side of the connecting box 204 on the front side of the rebound box 2. A ratchet 3 is fixed to the front end of the winding roller 201. A pawl 301 is rotatably connected to the front side of the connecting box 204. The pawl 301 is meshed with the ratchet 3. A torsion spring 302 is movably sleeved on the outer wall of the connecting box 204. The two ends of the torsion spring 302 are respectively fixed on both sides where the pawl 301 and the connecting box 204 are close to each other. A first limit plate 303 is fixed to one side of the pawl 301, and a second limit plate 304 is fixed to the front side of the connecting box 204. The first limit plate 303 is fitted with the bottom surface of the second limit plate 304. Through the pawl 301 and the ratchet 3, after the detection line 203 is pulled, the detection line 203 will not be affected by the pulling force of the winding spring 202, so that the connection between the detection line 203 and the detected device is more stable and reliable.

[0024] In the embodiment, the outer wall of the winding roller 201 is threadedly connected to two guide frames 4, the detection line 203 is inserted into the guide hole of the guide frame 4, the bottom surface of the guide frame 4 is fixed with a limiting rod 401, and the inner wall of the connecting box 204 is provided with a limiting groove 402. The limiting rod 401 and the limiting groove 402 are internally slidingly arranged. Through the arrangement of the guide frame 4, when the winding roller 201 rotates, it will drive the guide frame 4 to move horizontally, so that the detection line 203 is evenly wound on the winding roller 201, preventing the detection line 203 from overlapping when winding and getting stuck with the inner wall of the connecting box 204.

[0025] In the embodiment, a placement rack 5 is fixed to the top surface of the detector body 1 near the left and right sides, and the two rebound boxes 2 are both mounted inside the placement rack 5. The placement of the placement rack 5 facilitates the placement of the rebound box 2, so that the rebound box 2 is installed on the detector body 1 for easy taking when in use.

[0026] In an embodiment, the top surface of the placement rack 5 is rotatably connected with a strap 501, and the bottom surface of the strap 501 is respectively fixed with a sub-velcro 502 and a mother Velcro 503. Through the setting and use of the strap 501, the sub-velcro 502 and the mother Velcro 503, the rebound box 2 is conveniently fixed on the placement rack 5.

[0027] Working principle: When in use, insert the plug at one end of the detection line 203 into the socket of the detector body 1, then pull one end of the strap 501 to separate the child Velcro 502 from the mother Velcro 503, then remove the rebound box 2 together with the connection box 204 from the placement rack 5. In this process, one end of the detection line 203 is pulled and drives the winding roller 201 to rotate. At this time, the winding spring 202 is forced to shrink, and the other end of the detection line 203 also extends outward synchronously. When the winding roller 201 rotates, it drives the ratchet 3 to rotate, and the ratchet 3 toggles the pawl 301, and the pawl 30 After one tooth unit is moved, the torsion spring 302 resets the pawl 301 and meshes with the next tooth on the ratchet 301, thereby locking the winding roller 201 in the opposite direction. Then, the working environment continues to pull the detection line 203 until the alligator clip of the detection line 203 is connected to the detected device. Then, the detector body 1 can be started to perform comprehensive detection. After the detection is completed, the ratchet 301 is moved to separate the ratchet 301 from the ratchet 3. At this time, the winding roller 201 rotates in the opposite direction due to the elastic force of the coil spring 202, and the detection line 203 is quickly wound up.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
