[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0022] Example 1

[0023] like Figure 1 to Figure 4As shown, a knob-type quick-connect cup comb wire box assembly includes a cup comb 1, a wire box 2 and a pipe 3. A snap hole 21 is opened on one side of the wire box 2. The outer surface of the cup comb 1 is provided with an annular step portion 12 and at least a pair of limit blocks 11. The limit step 12 makes the cup comb 1 form a large outer diameter section and a small outer diameter section. The limit block 11 is arranged at the small outer diameter section of the cup comb 1, and the limit block 11 is spaced from the step surface of the limit step 12.

[0024] One end of the cup comb 1 passes through the buckle hole 21, and the side of the wire box 2 provided with the buckle hole 21 is clamped between at least one pair of limit blocks 11 and the step portion 12. Further, the annular outer wall of the cup comb 1 fits inside and outside the buckle hole 21; the limit block 11 includes a first wall 111 and a second wall 112 connected inside and outside facing the step portion 12, the first wall 111 is inclined outward and away from the step portion 12, the angle between the first wall 111 and the central axis of the cup comb 1 is 30-70 degrees, the second wall 112 is connected to the first wall 111 at an obtuse angle, and the first wall 111 cooperates with the step portion 12 to clamp the side of the wire box 2. The first wall 111 abuts against the inner wall of the side of the cup comb 1, and the step surface of the limit step 12 abuts against the outer wall of the side of the cup comb 1.

[0025] At least one pair of avoidance holes 22 are evenly distributed around the buckle hole 21 on one side of the wire box 2. Each of the avoidance holes 22 is connected to the buckle hole 21. At least one pair of limit blocks 11 pass through the at least one pair of avoidance holes 22 in a one-to-one correspondence and cooperate with the step portion 12 after rotation to clamp the side of the wire box 2. The avoidance holes 22 are used to allow the limit blocks 11 to pass through. The avoidance holes 22 and the limit blocks 11 are preferably set as one or two pairs. After the limit blocks 11 pass through the buckle holes 21, the cup comb is rotated 145 degrees or 90 degrees accordingly, so that the limit blocks 11 and the avoidance holes 22 are not on the same axis. Based on the friction between the cup comb 1 and the side of the wire box 2, the cup comb 1 and the wire box 2 are firmly connected.

[0026] The pipe 3 and the cup comb 1 fit tightly inside and outside. Furthermore, the inner cavity of the cup comb 1 includes a truncated cone-shaped socket cavity 13 and a truncated cone-shaped transition cavity 14, the small end of the socket cavity 13 is connected to the large end of the transition cavity 14, the pipe 3 fits tightly with the socket cavity 13 and the pipe 3 abuts against the connection between the socket cavity 13 and the transition cavity 14. A step surface 15 is formed at the connection between the socket cavity 13 and the transition cavity 14, and the pipe 3 abuts against the step surface 15. The angle between the wall of the socket cavity 13 and the central axis of the cup comb 1 is 1-3 degrees, which facilitates the smooth fitting of the pipe 3 and the cup comb 1, and is also conducive to promoting the tightness of the fitting of the pipe 3 and the cup comb 1.

[0027] Example 2

[0028] like Figures 5 to 8As shown, a knob-type quick-connect cup comb wire box assembly includes a cup comb 1, a wire box 2 and a pipe 3. A buckle hole 21 is opened on one side of the wire box 2. The outer surface of the cup comb 1 is provided with an annular step portion 12 and at least a pair of limit blocks 11. The limit step 12 forms a large outer diameter section and a small outer diameter section for the cup comb 1. The limit block 11 is arranged at the small outer diameter section of the cup comb 1, and the limit block 11 is spaced from the step surface of the limit step 12.

[0029] One end of the cup comb 1 passes through the buckle hole 21, and the side of the wire box 2 provided with the buckle hole 21 is clamped between at least one pair of limit blocks 11 and the step portion 12. Further, the annular outer wall of the cup comb 1 fits inside and outside the buckle hole 21; the limit block 11 includes a first wall 111 and a second wall 112 connected inside and outside facing the step portion 12, the first wall 111 is inclined outward and away from the step portion 12, the angle between the first wall 111 and the central axis of the cup comb 1 is 30-70 degrees, the second wall 112 is connected to the first wall 111 at an obtuse angle, and the first wall 111 cooperates with the step portion 12 to clamp the side of the wire box 2. The first wall 111 abuts against the inner wall of the side of the cup comb 1, and the step surface of the limit step 12 abuts against the outer wall of the side of the cup comb 1.

[0030] At least one pair of avoidance holes 22 are evenly distributed around the buckle hole 21 on one side of the wire box 2, and each of the avoidance holes 22 is connected to the buckle hole 21. At least one pair of limit blocks 11 pass through the at least one pair of avoidance holes 22 in a one-to-one correspondence and cooperate with the step portion 12 after rotation to clamp the side of the wire box 2. The avoidance holes 22 are provided to allow the limit blocks 11 to pass through.

[0031] The cup comb 1 is also provided with at least one pair of elastic buckles 16, and the side of the wire box 2 provided with the buckle holes 21 is also clamped between the at least one pair of elastic buckles 16 and the step portion 12. The cup comb 1 is provided with a through slot 17, and the elastic buckle 16 is arranged in the through slot 17, so that the elastic buckle 16 has a certain elasticity, can smoothly pass through the buckle holes 21 and then return to the initial state to clamp the side of the wire box 2; the elastic buckle 16 and the limit stopper 11 are distributed circumferentially.

[0032] The avoidance hole 22, the limit block 11, and the elastic buckle 16 are preferably arranged in one pair or two pairs. When the limit block 11 and the elastic buckle 16 pass through the buckle hole 21, the corresponding rotating cup comb 1 makes the limit block 11 and the elastic buckle 16 not on the same axis as the avoidance hole 22. Based on the friction between the cup comb 1 and the side of the wire box 2, the cup comb 1 and the wire box 2 are firmly connected; the setting of the elastic buckle 16 makes the connection between the cup comb 1 and the wire box 2 more stable.

[0033] The pipe 3 and the cup comb 1 fit tightly inside and outside. Furthermore, the inner cavity of the cup comb 1 includes a truncated cone-shaped socket cavity 13 and a truncated cone-shaped transition cavity 14, the small end of the socket cavity 13 is connected to the large end of the transition cavity 14, the pipe 3 fits tightly with the socket cavity 13 and the pipe 3 abuts against the connection between the socket cavity 13 and the transition cavity 14. A step surface 15 is formed at the connection between the socket cavity 13 and the transition cavity 14, and the pipe 3 abuts against the step surface 15. The angle between the wall of the socket cavity 13 and the central axis of the cup comb 1 is 1-3 degrees, which facilitates the smooth fitting of the pipe 3 and the cup comb 1, and is also conducive to promoting the tightness of the fitting of the pipe 3 and the cup comb 1.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
