Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection tools, and more specifically to a knob-type cup comb wire box assembly structure that can be quickly installed. Background Art

[0002] At present, cup combs are mostly installed to the junction box by threaded connection, such as Figure 1-3 As shown, the cup comb includes a first cup comb piece 30 and a second cup comb piece 31. The second cup comb piece 31 passes through the circular tube through hole 41 on the junction box 40 from the inside to the outside and abuts against the inner wall of the junction box 40. Then the first cup comb piece 30 is screwed to the second cup comb piece 31. The side plate of the junction box 40 is clamped between the threaded first cup comb piece 30 and the second cup comb piece 31. During this installation process, there will be problems such as misalignment of the threads, which need to be adjusted before they can be completely screwed together. In addition, when tightening and installing the first cup comb piece 30, the second cup comb piece 31 must always be firmly fixed, which is time-consuming and labor-intensive, and the installation is not convenient enough.

DETAILED DESCRIPTION

[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] like Figure 4-Figure 6 As shown, a knob-type cup comb wire box assembly structure that can be quickly installed includes a cup comb 1 and a wire box 2; Figure 2As shown, the cup comb 1 is in the shape of a cylinder with open ends, and the cup comb 1 includes a circular step portion 11 arranged on its outer wall, and the step portion 11 includes an axial surface 111 and a radial surface 112. The axial surface 111 and the radial surface 112 are both circular, and the axial surface 111 extends axially to one end of the cup comb 1. The cup comb 1 includes clamping teeth 12 arranged on its axial surface 111 and distributed circumferentially, and the clamping teeth 12 are axially spaced from the radial surface 112, and the number of the clamping teeth 12 is set to at least two evenly distributed circumferentially, preferably a pair.

[0021] like Figure 5 , Figure 6 As shown, the wire box 2 includes a box plate portion 21. Usually, the wire box 2 is a rectangular box-shaped structure with one end open, and is composed of five box plate portions 21. The box plate portion 21 is provided with a through hole 22. The through hole 22 includes a central circular hole 221 and side holes 222 distributed along the edge of the central circular hole 221 and capable of allowing the clamping teeth 12 to pass through. The central circular hole 221 is connected to each side hole 222. The number of the side holes 222 is the same as the number of the clamping teeth 12. The diameter of the central circular hole 221 is equal to the diameter of the axial surface 111.

[0022] like Figure 5 , Figure 6 As shown, the cup comb 1 passes through the box plate 21 and is clamped and fixed on the box plate 21, and the box plate 21 is tightly clamped between a circle of clamping teeth 12 and the radial surface 112. Further, when the cup comb 1 is clamped on the box plate 21, the clamping teeth 12 partially overlap or do not overlap with the side holes 222, and preferably, each clamping tooth 12 and each side hole 222 are staggered in the circumference, that is, they do not overlap; if the number of clamping teeth 12 is preferably a pair, the number of side holes 222 is also set as a pair, and when the cup comb 1 is clamped on the box plate 21, a pair of clamping teeth 12 is perpendicular to a pair of side holes 222. The axial surface 111 is tightly fitted with the hole wall of the central circular hole 221; the inner wall of the clamping teeth 12 facing the radial surface 112 is tightly fitted with the inner wall of the box plate 21, and the radial surface 112 is tightly fitted with the outer wall of the box plate 21, so that the cup comb 1 is tightly fixed and clamped on the wire box 2.

[0023] When installing the cup comb 1, align the clamping teeth 12 with the side holes 222, insert the cup comb 1 into the wire box 2, and make the radial surface 112 abut against the outer wall of the box plate 21. At the same time, make the step portion 11 pass through the central circular hole 221 and the clamping teeth 12 pass through the side holes 222. Then rotate the cup comb 1 at a certain angle so that the clamping teeth 12 partially overlap or do not overlap with the side holes 222, and the box plate 21 is tightly clamped between the clamping teeth 12 and the radial surface 112. In this way, the cup comb 1 is clamped and fixed on the box plate 21 to complete the installation. Through the rotating installation method of the cup comb 1, the cup comb 1 is quickly and stably installed, and the installation time and efficiency are shortened.
