Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more readily understand the advantages and features of the present invention, and to clearly and unequivocally define the scope of the present invention.
According to fig. 1 to 5, a square pipe of easily connecting, including four pipe walls 1, four pipe wall 1 encloses into square pipe main part, 1 one end of pipe wall is equipped with concave station 2, and the other end is equipped with draw-in groove 3, four on the pipe wall 1 concave station 2 is located same one side of square pipe main part passes through during the connection card 4 on the concave station 2 inserts thereby accomplish in the draw-in groove 3 and connect.
The concave station 2 is provided with a card 4, and the card 4 is matched with the concave station 2, so that the card 4 can be completely attached to the pipe wall 1 when being folded.
The card 4 through rotary mechanism with the concave station 2 is connected, the card 4 with the draw-in groove 3 cooperatees, makes the card 4 insert more firm stable in the time of in the draw-in groove 3, avoids its production to rock.
The rotating mechanism is composed of a mounting seat 5, two connecting seats 6 and a rotating positioning rod, the mounting seat 5 is fixedly mounted on the surface of the concave platform 2 and is located at one end of the square pipe main body, a limiting hole 7 is formed in the mounting seat 5, and the limiting hole 7 is used for limiting the position of the card 4 after rotation.
The two connecting seats 6 are mounted on the card 4 and connected with the mounting seat 5, a rotating hole 8 is formed in the connecting seat 6, and the rotating hole 8 is used for rotating the card 4.
The left end of the rotating hole 8 on the left side is closed, so that the rotating positioning rod is prevented from being exposed from the left side.
And a limiting ring 9 is arranged on the right side of the rotating hole 8 on the left side to prevent the rotating section 10 on the left side from being separated from the rotating hole 8, so that the rotating positioning rod falls out.
The right side rotatory hole 8 right-hand member is for opening the form, rotatory locating lever passes the right side in proper order rotatory hole 8 with insert the left side behind the locating hole in the rotatory hole 8, thereby make card 4 can round trip the rotation.
The distance between the two connecting seats 6 is the same as the width of the mounting seat 5, so that the quick-searching connecting seat 6 is more firmly connected with the mounting seat 5, and the card 4 cannot slide left and right.
The rotation positioning rod is composed of two rotation sections 10 and a limiting section 11, the two rotation sections 10 are located on two sides of the limiting section 11, and the rotation sections 10 are matched with the rotation holes 8, so that the card 4 is more stable when rotating.
The aperture of spacing hole 7 is less than the right side rotatory hole 8's aperture, thereby make spacing section 11 with get into the right side after spacing hole 7 breaks away from during rotatory hole 8, the right side can not scraped to external tooth 14 rotatory hole 8 inner wall internal tooth 13, thereby lead to the right side rotatory section 10 and right side rotatory hole 8 cooperation produces the clearance, influences card 4 is spacing.
The length of the limiting section 11 is the same as that of the limiting hole 7.
The left side rotatory section 10 is located the left side during 8 left side inner walls departments in rotatory hole, spacing section 11 inserts completely in the spacing hole 7, thereby it is right card 4 carries out the location of angle, and the left side rotatory section 10 is located the left side during 8 right side spacing rings 9 departments in rotatory hole, spacing section 11 with spacing hole 7 breaks away from.
The handle 12 is arranged on the right side of the rotary positioning rod, and the handle 12 is used for inserting and pulling out the rotary positioning rod.
During the use will firstly rotational positioning pole is pulled out for the left side rotatory section 10 with spacing ring 9 contacts, then adjusts according to required angle card 4, then will rotational positioning pole inserts, makes the left side rotatory section 10 and left side rotatory 8 left side inner walls of hole contact, spacing end and right side rotatory section 10 inserts respectively spacing hole 7 and right side in the rotatory hole 8, thereby it is right card 4 carries out the spacing of angle, will at last card 4 inserts in the draw-in groove 3 to accomplish final connection.
Compared with the prior art, the square pipe easy to connect has the advantages that the special connecting structures are arranged at the two ends of the square pipe, so that the two square pipes can be connected without external fasteners, and the square pipe is more convenient to connect.
