In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.
Example 1
As shown in fig. 1 to 6, a rod connection structure for a bed of the present utility model includes a tapered groove 1, a tube inner sleeve 2, and a movable outer flaring 3.
The conical groove 1 is arranged in a side wall opening 41 of a first rod 4, the opening of the conical groove 1 tapers towards the outer side direction of the side wall opening 41 to form a tapered opening 11, the movable outer flaring 3 is arranged at the end part of a second rod 5, the pipe inner sleeve member 2 comprises a circular truncated cone-shaped guide part 21, the diameter of a large head 211 with the larger diameter of the circular truncated cone-shaped guide part 21 is larger than the inner diameter of the movable outer flaring 3 and is not larger than the inner diameter of the tapered opening 11 of the conical groove 1, and the diameter of a small head 212 with the smaller diameter of the circular truncated cone-shaped guide part 21 is not larger than the inner diameter of the movable outer flaring 3, so that the large head 211 can be accommodated in the conical groove 1, and the small head 212 can be stretched into the movable outer flaring 3.
The outer diameter of the movable outer flaring 3 is not larger than the inner diameter of the tapered opening 11, the second rod 5 and the first rod 4 can be vertically arranged, the movable outer flaring 3 at the end part of the second rod 5 can be inserted into the side wall opening 41 of the first rod 4, the movable outer flaring 3 moves towards the big end 211 along the small end 212 of the circular table-shaped guide part 21 to deform and expand to form the expansion part 31, the expansion part 31 is positioned between the circular table-shaped guide part 21 and the side wall 12 of the tapered groove 1, and the outer diameter of the expansion part 31 is larger than the inner diameter of the tapered opening 11.
Therefore, with the connecting structure, the first rod 4 and the second rod 5 can be quickly installed, for example, only the small end 212 of the pipe inner sleeve 2 is required to be placed in the movable outer flaring 3 at the end part of the second rod 5, then the movable outer flaring 3 at the end part of the second rod 5 and the large end 211 of the pipe inner sleeve 2 are oriented towards and inserted into the conical groove 1 in the side wall opening 41 of the first rod 4, after the pipe inner sleeve 2 abuts against the bottom wall 13 of the conical groove 1, the force continues to apply force to expand and expand the movable outer flaring 3 of the second rod 5, and the end surface can also abut against the bottom wall 13 of the conical groove 1.
Of course, the large end 211 of the pipe inner sleeve 2 may be placed in the tapered groove 1 of the first rod 4 in advance, and then the movable outer flare 3 of the second rod 5 may be aligned with the pipe inner sleeve 2 and inserted along the truncated cone-shaped guide portion 21 to abut against the bottom wall 13 of the tapered groove 1, so as to form the expansion portion 31.
Therefore, the first rod 4 and the second rod 5 are in tight fit connection with the tapered slot 1 through the expansion part 31 and the pipe inner sleeve 2, and meanwhile, when the second rod 5 is pulled by external force, the movable outer flaring 3 drives the pipe inner sleeve 2 to move towards the tapered opening 11 of the tapered slot 1, and the end part of the second rod 5 cannot withdraw from the side wall opening 41 of the first rod because the outer diameter of the expansion part 31 attached to the pipe inner sleeve 2 is larger than the inner diameter of the tapered opening 11, so that stable connection between the first rod 4 and the second rod 5 is ensured.
In this embodiment, the first rod 4 and the second rod 5 may be metal rods, and at least two relief grooves 32 may be circumferentially spaced from the movable outer flaring 3 at the end of the corresponding second rod 5, so as to facilitate the expansion deformation of the movable outer flaring 3, and nine relief grooves 32 are disposed at the movable outer flaring 3 in this embodiment, so that the movable outer flaring 3 forms nine outer flaring body 33, and each outer flaring body 33 may be conveniently deformed along the circular table shape guiding portion 21.
The conical groove 1 can be concavely formed in a circular truncated cone 6, and the circular truncated cone 6 is fixed in the side wall opening 41 of the first rod 4 by welding or riveting, so as to facilitate production and manufacture based on the existing rod piece and reduce production cost.
Further, for the purpose of later detachable repeated installation, the pipe inner sleeve member 2 may be provided with an auxiliary fixing member 22, and the end portion of the second rod 5 where the movable outer flaring 3 is located is provided with a long through hole 51 corresponding to the auxiliary fixing member 22, the auxiliary fixing member 22 in this embodiment is a concave hole 221 formed in one side of the small end 212 of the pipe inner sleeve member 2, and after the movable outer flaring 3 begins to expand and deform, the concave holes 221 are located in the communication range of the long through hole 51. Therefore, when the second rod 5 and the first rod 4 need to be disassembled, the external tool 7, such as a screwdriver, is inserted into the concave hole 221 from the long through hole 51, and the external tool is applied with force to fix the pipe internal sleeve 2, so that the pipe internal sleeve 2 cannot move outwards when the outer flaring 3 is pulled outwards along with the movement of the second rod 5, the inner side of the expansion part 31 is free from support, and can be withdrawn from the tapered opening 11 after deformation and retraction, so that the separation of the first rod 4 and the second rod 5 is completed.
In this embodiment, the end of the small end 212 of the truncated cone-shaped guiding portion 21 of the tube inner sleeve 2 extends outwards to form a cylindrical portion 23, and the auxiliary fixing member 22 may be disposed on the cylindrical portion 23, and the cylindrical portion 23 also facilitates the installation of the tube inner sleeve 2 in the movable outer flaring 3.
In the drawings of the embodiment, four connecting structures are respectively arranged between the upper and lower cross bars 101 and the left and right vertical bars 102 of the headboard 10, so as to play a role in stable and reliable connection, and the connecting structures can be arranged at other positions of the bedstead, which are required to be connected with the rod members.
Example 2
As shown in fig. 7 and 8, the structure of the present embodiment 2 is substantially the same as that of the above-mentioned embodiment 1, and the main difference is that the auxiliary fixing member 22 of the present embodiment is a protrusion 222, and after the movable outer flaring 3 begins to expand and deform, the protrusion 222 is located and extends within the range of the elongated through hole 51, and when the protrusion 222 is fixed by a tool during disassembly, the pipe inner sleeve 2 can be fixed.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that equivalent changes and modifications can be made by those skilled in the art without departing from the principles of the present utility model, which still falls within the scope of the present utility model.
