[0019] 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.

[0020] Example 1

[0021] like Figure 1As shown, an internal plug-in quick-installation cup comb comprises a hollow cup comb body 1 with openings at both ends and an annular convex ring portion 2 formed by bending one end of the cup comb body 1 outward, and the cup comb body 1 is circumferentially provided with limit blocks 3 which can undergo elastic deformation inwards and outwards in the radial direction of the cup comb body 1. In fact, the cup comb body 1 is provided with circumferentially distributed through-holes 11, and the through-holes 11 are raised from the hole wall away from the convex ring portion 2 to form the limit block 3. There are gaps between the other hole walls of the through-hole 11 and the side walls of the limit block 3 and the free end face of the limit block 3, that is, they are not connected, and a U-shaped gap is formed between the through-hole 11 and the limit block 3, so that the limit block 3 can undergo elastic deformation. As shown Figure 1 As shown, the through-opening 11 is preferably a square opening, the limiting block 3 is preferably a square block, and the three side hole walls of the through-opening 11 are not connected to the two side walls of the limiting block 3 and the free end surface of the limiting block 3.

[0022] Further, the stopper 3 is axially arranged, and one end of the stopper 3 away from the convex ring portion 2 is connected to the cup comb body 1, where the one end refers to the connection end of the stopper 3 connected to the hole wall of the through hole 11, and the other end of the stopper 3 close to the convex ring portion 2 is a free end, and the free end is spaced from the convex ring portion 2, and a clamping area is formed between the free end and the convex ring portion 2, and the free end of the stopper 3 at least partially exceeds the outer wall of the cup comb body 1. In this embodiment, the stopper 3 is preferably provided in a pair.

[0023] Furthermore, the limit block 3 includes an outer wall 31, and the outer wall 31 is inclined outward and toward the direction close to the convex ring part 2, and the inclination angle is preferably 5-20 degrees. The radial width of the end face of the free end of the limit block 3 is greater than the wall thickness of the cup comb body 1, and the radial width of the end face of the free end of the limit block 3 is less than or equal to the width of the end face of the convex ring part 2 facing away from the free end of the limit block 3. The radial width of the connection end of the limit block 3 is preferably equal to the wall thickness of the cup comb body 1, and the inner wall of the limit block 3 is flush with the inner wall of the cup comb body 1. The cross-section of the limit block 3 on the axial plane is a right-angled trapezoidal structure, with a small thickness at the end away from the convex ring part 2 and a large thickness at the free end close to the convex ring part 2.

[0024] The free end face of the limiting block 3 is parallel to the end face of the convex ring portion 2 facing the free end of the limiting block 3, so that the cup comb body 1 can be clamped on the wire box more stably.

[0025] Example 2

[0026] like Figure 2-Figure 3 As shown, a wire box assembly includes a wire box 4 and the cup comb described in Example 1, wherein the wire box 4 includes a box plate portion 41, and the wire box 4 is generally in an open box shape, formed by 5 parts of the box plate portion 41, and the cup comb passes through the box plate portion 41 and is clamped on the wire box 4, and the box plate portion 41 is clamped between the free end of the limit block 3 and the convex ring portion 2.

[0027] The box plate portion 41 is provided with a through hole 42 , which is circular. When the cup comb is clamped on the wire box 4 , the outer wall of the cup comb body 1 is tightly fitted with the hole wall of the through hole 42 .

[0028] When installing the cup comb, the cup comb passes through the through hole 42 from the inside to the outside in the inner cavity of the wire box 4. Due to the elastic setting of the limit block 3, the limit block 3 is pushed inward when passing through the through hole 42. When the limit block 3 completely passes through the through hole 42, the limit block 3 returns to its original state and clamps the box plate part 41 between the convex ring part 2 and a circle of limit blocks 3.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
