The first plug portion 1 and the second plug portion 2 may be fitted to each other in various suitable manners. In order to facilitate the engagement between the first plug portion 1 and the second plug portion 2, it is preferable that the first plug portion 1 and the second plug portion 2 are provided with a first protrusion 5 and a first groove 6 on mutually facing surfaces thereof, respectively, and the first protrusion 5 is inserted into the first groove 6. The shape of the first projection 5 and the first groove 6 is not particularly limited, and for example, the first projection 5 may be a cylindrical projection, and the first groove 6 may be a cylindrical groove that matches the first projection 5. The layout of the first projection 5 and the first groove 6 is not particularly limited as long as the interfitting of the first plug portion 1 and the second plug portion 2 can be achieved by the first projection 5 and the first groove 6. In order to evenly distribute the force to which the first plug portion 1 and the second plug portion 2 are subjected, it is preferable that the first plug portion 1 and the second plug portion 2 are provided with a pair of first protrusions 5 arranged diagonally and a pair of first grooves 6 arranged diagonally corresponding to the first protrusions 5, respectively. In addition, the first protrusion 5 may be connected to the mutually facing surfaces of the first plug portion 1 and the second plug portion 2 by various suitable means, such as welding, screwing, etc., but the first protrusion 5 may be integrally formed with the mutually facing surfaces of the first plug portion 1 and the second plug portion 2.
In order to increase the fastening force of the connecting member when connecting two mutually perpendicular rods of the climbing frame using the connecting member for a climbing frame of the present invention, as shown in fig. 5, it is preferable that one end of the plug 10 where the insertion hole 12 is located is formed with a flange 7, and the flange 7 is interposed between the two mutually perpendicular rods of the climbing frame and abuts against the two mutually perpendicular rods when the connecting member of the present invention is connected. To facilitate the installation of the nut 3, the inside of the plug 10 is preferably provided with a plug cavity 8 matching the shape and size of the nut 3, the nut 3 being installed in this plug cavity 8.
There is no particular limitation on the number of nuts 3, and in order to increase the fastening force and improve the strength while avoiding the oversize of the plug 10, it is preferable that the first plug portion 1 and the second plug portion 2 cooperate with each other to form two plug cavities 8 arranged at intervals, the number of nuts 3 is two, and the two nuts 3 are respectively disposed in the two plug cavities 8. Alternatively, the number of nuts 3 may be one or more than two.
Preferably, a side of the plug cavity 8 close to the insertion hole 12 is provided with a tapered hole 9, and the bore diameter of the tapered hole 9 gradually decreases in a direction from the plug cavity 8 to the insertion hole 12. Then, as shown in fig. 5, as the bolt 4 is tightened, the nut 3 in the plug 10 moves toward the tapered hole 9 to spread the first plug portion 1 and the second plug portion 2, and the fit between the outer circumferential surface of the plug 10 and the inner circumferential surface of the first rod 13 of the creel becomes tighter, thereby connecting the first rod 13 and the second rod 14 more tightly.

At the same time, the second projection, which may be in the form of a plastic or elastic sheet for example, is designed so as not to impede the movement of the nut 3 towards the tapered bore 9 when tightening the bolt. When tightening the bolt, the forward movement of the nut 3 will press down the second protrusion so that the nut 3 can continue to move forward. In addition, the second protrusion 11 may be connected to the inner surface of the plug 10 by various suitable means, such as welding, but the second protrusion 11 may also be integrally formed with the inner surface of the plug 10. The number of the second protrusions 11 is not particularly limited, and for example, as shown in fig. 3 and 4, the number of the second protrusions 11 for holding one nut 3 may be four, and the four second protrusions 11 may be spaced along the periphery of the side of the plug cavity 8 facing the flange 7.
The outer peripheral surface of the plug 10 needs to match the inner peripheral surface of the hollow rod of the climbing frame, typically the plug 10 is a cylindrical sleeve. Of course, the shape of the plug 10 may vary with the shape of the hollow rod of the climbing frame, for example, when the hollow rod is square prism in shape, the plug 10 is correspondingly square prism in shape. The material of the plug 10 is not particularly limited, and it is preferable that the plug 10 is a plastic plug in order to reduce the weight of the plug 10 and facilitate the forming.
In order to save material, as shown in fig. 5, it is preferable that the plug 10 is provided with an annular groove 16 on its inner circumferential surface.
As shown in fig. 5, the connection member for a climbing stand according to the present invention requires the connection between two rods of the climbing stand to be realized by the connection of the bolt and the nut, and for convenience of use, it is preferable that the connection member further includes a bolt 4 matched with the nut 3, and the bolt 4 can be inserted into the plug 10 through the insertion hole 12 and connected with the nut 3. Alternatively, the screw 4 may not be a component of the connection, but may be additionally purchased by the user as required.

In order to reduce the length of the bolt and improve the aesthetic appearance of the climbing frame, preferably, the second rod 14 is further provided with a plug mounting hole 15 with an axis perpendicular to the length direction of the second rod 14, the plug mounting hole 15 and the bolt mounting hole 17 are arranged on two sides of the second rod 14 in an opposite mode, and the plug 10 and the first rod 13 penetrate through the plug mounting hole 15 and are inserted into the second rod 14.
As shown in fig. 5, the radial dimension of the flange 7 is generally the same as the radial dimension of the first rod 13.
Next, the working principle of the connecting member for a climbing stand according to the present invention will be described in detail. As shown in fig. 5 to 7, first, the plug 10 is inserted into the first rod 13 so that the inside surface of the flange 7 of the plug 10 abuts against the end surface of the first rod 13, then the plug 10 is inserted into the second rod 14 through the plug mounting hole 15 together with the first rod 13 so that the outside surface of the flange 7 abuts against the inside surface of the second rod 14 and the bolt mounting hole 17 in the second rod 14 is aligned with the insertion hole 12, the shank of the bolt 4 is connected with the nut 3 through the bolt mounting hole 17 and the insertion hole 12 in this order, and as the bolt 4 is tightened, the nut 3 in the plug 10 moves toward the tapered hole 9 to spread the first plug portion 1 and the second plug portion 2 apart to tighten the fit between the outer peripheral surface of the plug 10 and the inner peripheral surface of the first rod 13 of the climbing frame more tightly, thereby connecting the first rod 13 and the second rod 14 more tightly.
