Claims

1. A cable reel, comprising a cable reel side plate (1), the cable reel side plate (1) being fixed to an external electrical housing, a take-up reel (2) being rotatably mounted at one end of the cable reel side plate (1), and a take-up button (3) being slidably mounted at the other end in the radial direction, a coil spring (4) being mounted on the cable reel side plate (1), one end of the coil spring (4) being connected to the take-up reel (2), characterized in that, The winding reel side plate (1) is equipped with a limiting buckle (5) that can slide in the axial direction. The limiting buckle (5) is located below the take-up button (3). The bottom of the limiting buckle (5) is provided with a locking tongue (6). The side end face of the take-up wheel (2) is provided with a locking flange (7) that can cooperate with the locking tongue (6). When the take-up button (3) is pressed down in the radial direction, the limiting buckle (5) is driven to slide in the axial direction, so that the locking tongue (6) is disengaged from the locking flange (7). At this time, the coil spring (4) drives the take-up wheel (2) to automatically take up the wire clockwise.

2. The reel according to claim 1, characterized in that, The lower end of the take-up button (3) is provided with a first inclined guide surface (8), and the limiting buckle (5) is provided with a second inclined guide surface (9) corresponding to the first inclined guide surface (8). By pushing the second inclined guide surface (9) through the first inclined guide surface (8), the limiting buckle (5) can be driven to slide along the axial direction.

3. The reel according to claim 1, characterized in that, The winding reel side plate (1) is provided with an installation cavity (10) along the axial direction for sliding the limiting buckle (5). The limiting buckle (5) is provided with a through groove (11). The installation cavity (10) is provided with a positioning plate (12). The positioning plate (12) passes through the through groove (11). A first return spring (13) is installed in the through groove (11) and one end of the first return spring (13) abuts against the positioning plate (12).

4. The reel according to claim 3, characterized in that, The side plate (1) of the reel has a mounting groove (16) formed around the outside of the shaft, and the mounting cavity (10) is located in the mounting groove (16).

5. The reel according to claim 1, characterized in that, The locking tongue (6) has a third inclined guide surface (14) on one side, and the locking flange (7) has a fourth inclined guide surface (15) corresponding to the third inclined guide surface (14) on one side.

6. The reel according to claim 4, characterized in that, The mounting groove (16) is provided with a second return spring (30), which abuts against the bottom of the take-up button (3). A brake wheel (17) is movably installed in the mounting groove (16). A friction part (18) is provided on one side of the mounting groove (16), and an opening (19) is provided on the other side. The inner side of the take-up wheel (2) passes through the opening (19) and is placed in the mounting groove (16), so that the brake wheel (17) is located between the take-up wheel (2) and the friction part (18).

7. The reel according to claim 6, characterized in that, The take-up button (3) is provided with an inclined movable groove (20), and the brake wheel (17) is provided with a guide post (21), which is placed in the movable groove (20).

8. The reel according to claim 7, characterized in that, The side plate (1) of the reel is provided with a spring mounting seat (26), the spring (4) is wound in the spring mounting seat (26), the take-up reel (2) is provided with a positioning buckle (27), and one end of the spring (4) is inserted and fixed in the positioning buckle (27).

9. The reel according to claim 1, characterized in that, The side plate (1) of the reel is symmetrically provided with guide blocks (28), and the take-up button (3) is movably inserted into the guide block (28).

10. The reel according to claim 1, characterized in that, The winding reel side plate (1) is also provided with a connecting shaft (29), and the winding reel (2) is rotatably mounted on the connecting shaft (29).
