The utility model has the advantages of the equipment is convenient, avoids having the flexibility relatively poor and dead phenomenon of card to appear in the assembling process.

The utility model discloses the accessible improves with following scheme:

the fixed section is circumferentially provided with clamping teeth at intervals; the circumference of the rotation limiting section is provided with a plurality of convex ribs which extend axially along the insertion part and can be in insertion fit with the latch, and when the rotation limiting section is located at the fixed section and is in fit butt joint with the fixed section, the convex ribs are clamped in the latch.

The latch length direction extends along the axial direction corresponding to the first through hole and the second through hole, and a distance is reserved between the end faces of the two ends in the latch length direction and the upper end face and the lower end face of the connecting piece.

Each latch is distributed on the hole wall at equal intervals by a rotating shaft around the central shaft of the corresponding first through hole and the central shaft of the corresponding second through hole.

The included angle formed by two opposite tooth surfaces of each clamping tooth is less than 30 degrees.

First hurdle frame and second hurdle frame are the tetragonal body, and four angles of tetragonal body all set up grafting portion.

Detailed Description

The connecting structure of a fence as shown in fig. 1 to 5 comprises a first fence 1, a second fence 2 and a connecting piece 3, wherein the first fence 1 and the second fence 2 are connected through the connecting piece 3 to form the fence.

As shown in fig. 6 to 10, the connecting member 3 has a first through hole 311 and a second through hole 312, the inner wall of the first through hole 311 and the inner wall of the second through hole 312 are both divided into a rotating section 32 and a fixing section 33 in the axial direction, the fixing section 33 is located in the middle area of the inner wall corresponding to the first through hole 311 and the inner wall corresponding to the second through hole 312, more specifically, the fixing section 33 is provided with latches 34 at intervals in the circumferential direction, the length direction of the latches 34 extends along the axial direction corresponding to the first through hole 311 and the second through hole 312, and a distance L is provided between the end surfaces of both ends of the latches 34 in the length direction and the upper and lower end surfaces of the connecting member 3. Each latch 34 is distributed on the hole wall at equal intervals around the central axis of the corresponding first through hole 311 and second through hole 312 by a rotating shaft. Preferably, the angle a between two opposite tooth surfaces of each latch 34 is less than 30 degrees

The first rail frame 1 and the second rail frame 2 are respectively provided with an inserting part 4, the inserting part 4 is divided into a pivoting section 41 and a rotation limiting section 42 in the axial direction, and the rotation limiting section 42 is positioned at one end close to the root part of the inserting part 4; more specifically, the rotation limiting section 42 is provided with a plurality of ribs 43 extending axially along the insertion portion 4 and capable of being inserted into the latch 34. In this embodiment, the first hurdle frame 1 and the second hurdle frame 2 are both square bodies, and the four corners of each square body are provided with the insertion parts 4, so that the same purpose can be achieved by only arranging the insertion parts 4 on the two sides of each square body.

The first rail frame 1 and the second rail frame 2 are connected through the connecting piece 3, when the pivoting section 41 is in matched butt joint with the rotating section 32, the first rail frame 1 and the second rail frame 2 can relatively rotate in the circumferential direction of the inserting part 4. When the rotation limiting section 42 falls on the fixed section 33 and is in matched butt joint with the fixed section, the first rail frame 1 and the second rail frame 2 are relatively fixed in the circumferential direction of the inserting part 4, and more specifically, when the rotation limiting section 42 falls on the fixed section 33 and is in matched butt joint with the fixed section, the convex rib 43 is clamped in the clamping tooth 34.
