[0029] Reference Figures 1 to 4 , the utility model provides a double-joint boom, comprising a first boom unit 1, a second boom unit 2 and a cushion sleeve 3;
[0030] The second end of the first boom unit 1 is connected to the first external structure, and the second end of the second boom unit 2 is connected to the second external structure. The main body of the first boom unit 1 and the first external structure can be relatively rotated, and the main body of the second boom unit 2 and the second external structure can be relatively rotated. In this embodiment, the first external structure is preferably a machine tool, and the second external structure is preferably a chassis display screen;
[0031] The cushion cover 3 has two sides, the first boom unit 1 is located on one side thereof, and the second boom unit 2 is located on the other side thereof, one side of the cushion cover 3 is connected to the first end of the first boom unit 1 and the other side of the cushion cover 3 is rotatably connected to the second end of the second boom unit 2;
[0032] Alternatively, one side of the cushion sleeve 3 is connected to the second end of the second boom unit 2 and the other side of the cushion sleeve 3 is rotatably connected to the first end of the first boom unit 1;
[0033] With this arrangement, one of the first boom unit 1 and the second boom unit 2 can move synchronously with the cushion sleeve 3 and the other can rotate relative to the cushion sleeve 3. Therefore, the first boom unit 1 and the second boom unit 2 can rotate relative to each other and can rotate a certain angle with the assistance of the cushion sleeve 3.
[0034] By splitting the original flat-mounted boom into a first boom unit 1 and a second boom unit 2, and arranging a cushion sleeve 3 between the two, the first boom unit 1 and the second boom unit 2 can achieve relative rotation with the assistance of the cushion sleeve 3, thereby reducing the overall rotation radius of the boom, effectively reducing long-distance back-and-forth movement during the rotation process, making the operation more flexible and convenient, and improving work efficiency.
[0035] The middle part of the cushion cover 3 has a through opening, so that the double-joint boom has a complete cavity, which can accommodate the line, make the exterior more beautiful, avoid the problem of line entanglement, improve work efficiency and reduce labor costs.
[0036] The double-jointed boom also includes a first nut sleeve 4 and a first round nut 5. The first boom unit 1 includes a first elbow structure 11, and the second boom unit 2 includes a second elbow structure 21. The first nut sleeve 4 sequentially passes through the first end of the first elbow structure 11, the washer 3, and the second end of the second elbow structure 21, and then forms a threaded connection with the first round nut 5. This arrangement can limit the axial displacement between the first elbow structure 11, the washer 3, and the second elbow structure 21.
[0037] The sleeve 3 is connected to the first end of the first elbow structure 11 and is rotatably connected to the second end of the second elbow structure 21, or the sleeve 3 is connected to the second end of the second elbow structure 21 and is rotatably connected to the first end of the first elbow structure 11. With this arrangement, one of the first elbow structure 11 and the second elbow structure 21 can move synchronously with the sleeve 3 and the other can rotate relative to the sleeve 3. Therefore, relative rotation can be achieved between the first boom unit 1 and the second boom unit 2, and can be rotated to a certain angle with the assistance of the sleeve 3.
[0038] In this embodiment, the preferred connection form is that the cushion sleeve 3 is connected to the first end of the first elbow structure 11 and is rotatably connected to the second end of the second elbow structure 21;
[0039] Specifically, a first protrusion 111 is provided on the outer edge of the first end of the first elbow structure 11, and a limiting groove 31 is provided on the side of the gasket 3 close to the first elbow structure 11. The first protrusion 111 is embedded in the limiting groove 31 to connect the first elbow structure 11 and the gasket 3. Since the axial displacement between the first elbow structure 11 and the gasket 3 has been limited by the first nut sleeve 4 and the first round nut 5, the first elbow structure 11 and the gasket 3 can achieve synchronous movement.
[0040] A second protrusion 211 is provided on the outer edge of the second end of the second elbow structure 21. A rotation groove 32 is circumferentially formed on the side of the sleeve 3 close to the second elbow structure 21. The second protrusion 211 can move circumferentially within the rotation groove 32 to rotatably connect the second elbow structure 21 to the sleeve 3.
[0041] It is worth noting that the two ends of the rotation groove 32 are not connected, that is, the rotation groove 32 does not cover the entire circumference. Since the coverage range of the rotation groove 32 corresponds to the maximum rotation angle between the second elbow structure 21 and the cushion sleeve 3, during actual production, the rotation groove 32 can be flexibly opened according to actual usage requirements to correspond to the maximum rotation angle.
[0042] The first boom unit 1 further includes a first mounting connecting pipe 12, a third elbow structure 13, a first connecting seat 14, a second nut sleeve 15 and a second round nut 16;
[0043] The first end of the first installation connecting pipe 12 is connected to the second end of the first elbow structure 11. The connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble. The second end of the first installation connecting pipe 12 is connected to the first end of the third elbow structure 13. The connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble.
[0044] The second nut sleeve 15 sequentially passes through the second end of the third elbow structure 13 and the first connecting seat 14 to form a threaded connection with the second round nut 16. The second nut sleeve 15 and the second round nut 16 can limit the axial displacement between the third elbow structure 13 and the first connecting seat 14, while allowing relative rotation between the two.
[0045] The first connecting seat 14 is connected to the first external structure, and the connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble.
[0046] The second boom unit 2 further includes a second mounting connecting pipe 22, a fourth elbow structure 23, a third mounting connecting pipe 24, a transition connecting seat 25, a second connecting seat 26, a connecting nut 27 and an adjustable tightening handle 28;
[0047] The second end of the second installation connecting pipe 22 is connected to the first end of the second elbow structure 21. The connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble. The first end of the second installation connecting pipe 22 is connected to the second end of the fourth elbow structure 23. The connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble.
[0048] The first end of the fourth elbow structure 23 is connected to the second end of the third installation connecting pipe 24. The connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble;
[0049] The axis of the second mounting connecting tube 22 is perpendicular to the axis of the third mounting connecting tube 24. The first end of the third mounting connecting tube 24 passes through the transition connecting seat 25 and the second connecting seat 26 in sequence and then forms a threaded connection with the connecting nut 27. The connecting nut 27 and the third mounting connecting tube 24 can limit the axial displacement between the transition connecting seat 25 and the second connecting seat 26, while allowing relative rotation between the two.
[0050] The adjustable tightening handle 28 is connected to the second connecting seat 26. When the adjustable tightening handle 28 is in a tightened state, it can be pressed into contact with the first end of the third installation connecting tube 24, thereby limiting the relative rotation between the transition connecting seat 25 and the second connecting seat 26. When the adjustable tightening handle 28 is in a loose state, it can be released from the pressing contact with the first end of the third installation connecting tube 24. At this time, the relative rotation between the transition connecting seat 25 and the second connecting seat 26 is no longer restricted, allowing the transition connecting seat 25 and the second connecting seat 26 to achieve relative rotation.
[0051] The second connecting seat 26 is connected to the second external structure, and the connection here is preferably a bolt connection, which makes the connection firm and easy to assemble and disassemble.
[0052] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
