DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0026] like Figure 1-5As shown, an octagonal tube assembly auxiliary tool comprises: a strip-shaped positioning arm 2 that can be fitted and inserted into the interior of the octagonal tube 1 and a mounting tube 3 that is arranged in the same length direction as the positioning arm 2 and fixedly mounted on the end of the positioning arm 2, the positioning arm 2 is formed with a strip-shaped slot 5 with both ends open for accommodating a plurality of nuts 4 on one side facing the outer wall of the octagonal tube 1, the interior of the positioning arm 2 is formed with a mounting cavity, a positioning unit is arranged in the mounting cavity, the positioning unit comprises a plurality of retaining members 6 that are arranged at intervals along the length direction of the positioning arm 2 and can all slide through the mounting inner cavity and insert into the strip retaining slot 5, a transmission connection mechanism connected to the plurality of retaining members 6 and an elastic member 7 for pushing the plurality of retaining members 6 to pass out of the mounting cavity, the transmission connection mechanism is connected with a connecting rope 8 that passes through the positioning arm 2 and through the mounting tube 3.

[0027] The two opposite side walls of the nut 4 can respectively contact the two side walls of the strip slot 5 to limit the rotation of the nut 4. The positioning piece 6 passes out of the positioning arm 2 and is inserted into the strip slot 5 to contact the nut 4, which is used to limit the nut 4 from moving along the length direction of the strip slot 5 in the strip slot 5. Because the positioning arm 2 slides against the inner wall of the octagonal tube 1, after the positioning arm 2 is inserted into the octagonal tube 1, the nut 4 will not move out of the strip slot 5 due to the interception effect of the inner wall of the octagonal tube 1. Therefore, when the positioning arm 2 is inserted into the octagonal tube 1, the position of the nut 4 can be adjusted by pulling or pushing the installation tube 3, so that the installer can install the bolt on the corresponding nut 4. Through the auxiliary device, several nuts 4 can be easily sent into the octagonal tube 1, which is convenient for the installer to install the bolt.

[0028] When several bolts are installed, the mounting tube 3 is pulled outward at this time, and the retaining member 6 will be blocked by the nut 4, so it is necessary to pull the connecting rope 8. The connecting rope 8 drives several retaining members 6 to move closer to the mounting inner cavity through the transmission connection mechanism, so that the end of the retaining member 6 located in the strip slot 5 moves out of the strip slot 5. While pulling the connecting rope 8, the mounting tube 3 is pulled at the same time, and the positioning arm 2 is pulled out of the mounting tube 3.

[0029] When it is necessary to separate the bolt and nut 4, pull the connecting rope 8 relative to the mounting tube 3 so that the end of the retaining piece 6 located in the strip slot 5 slides close to the mounting inner cavity, then hold the mounting tube 3, insert the positioning arm 2 into the octagonal tube 1, at this time, the strip slot 5 will be sleeved on several nuts 4, after aligning the nuts 4 with several retaining pieces 6 one by one, after removing the bolts, pull out the positioning arm 2, and then the several nuts 4 can be taken out together.

[0030] A strip-shaped avoidance groove 9 is recessed on the bottom wall of the strip-shaped slot 5 and has the same length direction and both ends are open to accommodate the end of the bolt.

[0031] In order to improve the connection strength between the bolt and the nut 4, after the bolt is tightened, the end of the bolt connected to the nut 4 will protrude outward, so a strip avoidance groove 9 is provided to accommodate the end of the bolt.

[0032] The locking member 6 includes a pair of positioning rods 10 which are arranged in parallel and can slide through the positioning arm 2 and insert into the strip-shaped slot 5 , and a connecting portion 11 which can contact the inner wall of the installation cavity and is fixedly connected to the pair of positioning rods 10 .

[0033] The elastic member 7 will push the connecting part 11 through the transmission connection mechanism, thereby pushing the positioning rod 10 to pass out of the positioning arm 2 and insert into the strip slot 5. When the connecting part 11 fits the inner wall of the installation cavity, the end of the positioning rod 10 is inserted into the strip slot 5, and the connecting part 11 fits the installation cavity and also plays a limiting role; when the connecting rope 8 is pulled, the connecting part 11 will be pulled through the transmission connection mechanism, thereby driving the positioning rod 10 to slide close to the installation cavity.

[0034] The transmission connection mechanism includes a sliding arm 12 which is arranged with the same length as the positioning arm 2 and is slidably installed in the installation cavity along its own length, and a plurality of connecting rods 13 which are respectively hinged to the corresponding connecting parts 11. The end of each connecting rod 13 away from the connecting part 11 is hinged to a connecting piece 14 which is fixedly connected to the sliding arm 12. The end of the sliding arm 12 close to the installation tube 3 slides outwardly, passes through the positioning arm 2, is inserted into the installation tube 3, and is fixedly connected to the end of the connecting rope 8.

[0035] The elastic member 7 is a return spring sleeved on the sliding arm 12, a limiting ring 15 is fixedly sleeved on the sliding arm 12, a limiting sleeve 16 is fixedly installed on the inner wall of the installation cavity, through which the sliding arm 12 slides and is located on the side of the limiting ring 15 close to the installation tube 3, and the two ends of the spring are respectively in conflict with the limiting ring 15 and the limiting sleeve 16.

[0036] The elastic member 7 pushes the slide arm 12 to slide through the limit ring 15. When the slide arm 12 slides, it will move with several connecting members 14. Several connecting members 14 will push the connecting part 11 to move close to the strip groove 5 through the connecting rod 13, thereby pushing the end of the positioning rod 10 to pass through the positioning arm 2 and insert into the strip groove 5. The nut 4 is placed between a pair of positioning rods 10, which can limit the nut 4 from sliding in the strip groove 5.

[0037] The positioning arm 2 includes an arm body 17 with a recessed installation inner cavity and a cover body 18 mounted on the arm body 17 through a plurality of mounting bolts to cover the installation inner cavity.

[0038] The connecting portion 11 slides through at least one guide bolt 19 fixedly mounted on the inner wall of the mounting cavity and arranged in the same length direction as the positioning rod 10 , and the guide bolt 19 is sleeved with an auxiliary spring 20 that abuts against the connecting portion 11 and the head of the guide bolt 19 .

[0039] The auxiliary spring 20 functions to push the connecting portion 11 to move closer to the strip-shaped slot 5 , thereby pushing the positioning rod 10 to slide, so that the end of the positioning rod 10 is inserted into the strip-shaped slot 5 .

[0040] A pull ring 21 is fixedly connected to the end of the connecting rope 8 passing through the mounting pipe 3 .

[0041] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments.
