The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 3, the utility model provides a square pipe connection structure, including square pipe 1 and square pipe core 2, square pipe core 2 is inserted and is arranged in square pipe 1 and can link its rotation, wherein square pipe 1 is the cavity tubulose, and square pipe core 2 inserts the one end in square pipe 1 and is the square column. Square pipe 1 and square between the pipe core 2 be connected with shell fragment 3, shell fragment 3 stretches into and manages 1 interior and square the inner wall of pipe 1 along length direction joint fixed in side.
Through fixing shell fragment 3 and square tube core 2, when square tube core 2 and square tube 1 equipment, with the help of shell fragment 3 and square tube 1 joint are fixed, make square tube core 2 and square tube 1 reciprocal anchorage, realized square tube core 2 and square tube 1's fast assembly, the assembling process is convenient and fast more.
Further, the shell fragment 3 includes basal portion 31 and deformation portion 32, basal portion 31 with the square tube core 2 is connected fixedly, but deformation portion 32 bending type connect in but basal portion 31 is last and elastic deformation, set up on the lateral wall of square tube 1 and supply deformation portion 32 buckles into the mounting hole 11 that makes shell fragment 3 and square tube 1 joint. Preferably, the mounting hole 11 penetrates to an outer side wall of the square pipe 1. In other embodiments, the side wall of the square tube 1 may not be provided with the mounting hole 11, and the inner wall of the square tube 1 is provided with a clamping block clamped with the deformation portion 32, and the clamping and fixing are realized by utilizing a clamping and matching structure of the deformation portion 32 and the clamping block.
When shell fragment 3 penetrated to square intraductal 1, the deformation portion 32 was bent and is out of shape to reset and detain to mounting hole 11 when removing to mounting hole 11 department in, make shell fragment 3 fixed with 1 joint of square pipe, realized the fast assembly of square pipe 1 and square pipe core 2. In addition, because the mounting hole 11 runs through to the outer wall of square pipe 1, penetrate to the mounting hole 11 in with the help of instrument or finger, press deformation portion 32, can follow square pipe core 2 and extract in the square pipe 1, it is more convenient to dismantle.
In this embodiment, only one side wall of the square tube 1 is provided with the mounting hole 11, in other embodiments, the four side walls of the square tube 1 can be provided with the mounting holes 11, the complexity of assembling the square tube 1 and the square tube core 2 is reduced by providing the plurality of mounting holes 11, and the elastic piece 3 can be fixed with the square tube 1 in any direction.
Furthermore, the deformation portion 32 includes a connection portion 321 and an abutting portion 322, the abutting portion 322 is parallel to the base portion 31 and is clamped in the mounting hole 11, and the connection portion 321 is connected between the base portion 31 and the abutting portion 322 and can drive the deformation portion 32 to bend and deform when contacting the square pipe 1.
When the elastic sheet 3 is buckled into the mounting hole 11, the abutting part 322 abuts against the inner wall of the mounting hole 11, and because the abutting part 322 is parallel to the base part 31, namely the abutting part 322 is parallel to the side wall of the square tube 1, when the square tube 1 receives an external force far away from the direction of the square tube core 2, the abutting part 322 is not easy to deform, and the connection reliability of the square tube 1 and the square tube core 2 is improved.
Furthermore, the square tube core 2 is provided with an installation groove 21 for the elastic sheet 3 to be embedded into. On the one hand, mounting groove 21 provides the storage space for shell fragment 3, ensures that the lateral wall of square tube core 2 can keep the butt with square tube 1's inside wall, and in addition, mounting groove 21 also provides the positioning action for shell fragment 3, avoids shell fragment 3 to take place to rock, has further promoted square tube core 2 and square tube 1's reliability of being connected.
Further, the connection portion 321 is connected to one end of the base portion 31 and extends obliquely in a direction away from the other end of the base portion 31, and the contact portion 322 is connected to a side of the connection portion 321 away from the base portion 31. In other embodiments, the abutting portion 322 may also be connected to the side of the connecting portion 321 close to the base portion 31, that is, the abutting portion 322 is located above the base portion 31.
In this embodiment, through setting up connecting portion 321 slope, when square tube core 2 inserts to square tube 1 in, connecting portion 321 and the butt of square tube 1 of shell fragment 3 take place to warp, and the connecting portion 321 that the slope set up has played the effect of direction, and the shell fragment 3 of being more convenient for takes place to warp, makes the assembling process of square tube core 2 and square tube 1 more laborsaving. And set up butt portion 322 in one side that basal portion 31 was kept away from to connecting portion 321, both can prevent the sheltering from to basal portion 31, reduce the operation degree of difficulty of basal portion 31 and the equipment of square tube core 2, can make the contained angle of basal portion 31 and connecting portion 321 be the obtuse angle again, make shell fragment 3 change easily when inserting to square tube 1 and take place the deformation.
In this embodiment, the base portion 31 is provided with an avoiding hole 311, the square tube core 2 is provided with a fastening hole 22 corresponding to the avoiding hole 311, and the elastic sheet 3 penetrates through the avoiding hole 311 by means of a fastening member and then is connected with the fastening hole 22 so as to be fixed to the square tube core 2. In this embodiment, the fastening hole 22 is opened at the bottom of the mounting groove 21, and the fastening member is a screw.
Further, the width of the base portion 31 is greater than the width of the deformation portion 32, the mounting groove 21 includes a first positioning groove 211 and a second positioning groove 212 which are communicated with each other and into which the base portion 31 and the deformation portion 32 are correspondingly fitted, and correspondingly, the width of the first positioning groove 211 is greater than the width of the second positioning groove 212.
Because the width of first constant head tank 211 and second constant head tank 212 is different, when mounting groove 21 was put into to shell fragment 3, played the effect of location for basal portion 31, restriction shell fragment 3 took place to rock, and is more stable when twisting the screw and fix, has reduced the operation degree of difficulty, improves the installation effectiveness.
Further, a support step 2121 is formed in the second positioning groove 212, and is capable of providing support for the deformation portion 32 when bending, preferably, a top surface of the support step 2121 is parallel to a bottom wall of the first positioning groove 211 and is capable of providing support for the abutting portion 322 of the elastic sheet 3, and a side surface of the support step 2121 is inclined and is capable of providing support for the connecting portion 321 of the elastic sheet 3.
Through setting up and holding step 2121, provide certain limiting displacement to the deformation of deformation portion 32, prevent that shell fragment 3 from warping the range too big and becoming invalid when taking place to bend to warp, ensured the elasticity performance of shell fragment 3, further improved the connection reliability of square pipe 1 and square pipe core 2.
Further, the square tube core 2 is provided with a stop step 23 abutting against the end of the square tube 1. Specifically, one end of the square tube core 2 extends into the square tube 1, and the other end is connected with the handle head 5 and is cylindrical.
