DETAILED DESCRIPTION
[0027] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.
[0028] In this article, terms such as "upper, lower, inside, outside" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" are only used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.
[0029] Example 1
[0030] like Figure 1 As shown, the telescopic arm for performing automatic reset of end rotation disclosed in this embodiment includes a connecting arm 1, a reset guide seat 2 installed on the top of the connecting arm 1, and a connecting assembly 3; the reset guide seat 2 is provided with a rotation guide groove 21, and the connecting assembly 3 includes a mounting seat 31 installed on the connecting arm 1 and moving back and forth along the connecting arm 1, and a connecting rod 32 rotatably installed on the mounting arm mounting seat 31, the connecting rod 32 follows the mounting seat 31 to move up and down so that the top of the connecting rod 32 slides up and down along the rotation guide groove 21; wherein, the connecting rod 32 moves downward along the rotation guide groove 21, the connecting rod 32 rotates forwardly around its axis by a certain angle, and when the connecting rod 32 slides out of the rotation guide groove 21, the connecting rod 32 is in a rotationally locked state; the connecting rod 32 moves upward along the rotation guide groove 21, the connecting rod 32 rotates in the opposite direction around its axis by a certain angle to reset, and when the connecting rod 32 slides into the rotation guide groove 21, the connecting rod 32 is in a rotationally unlocked state. It can be understood that the rotation guide groove 21 passes through the reset guide seat 2 from bottom to top and is twisted counterclockwise by a certain angle from bottom to top. The twisting angle of the rotation guide groove 21 is set according to the angle at which the connecting rod 32 needs to rotate, and is not limited here; in addition, the rotation locked state refers to the state in which the connecting rod 32 cannot rotate around its axis, and the rotation unlocked state refers to the state in which the connecting rod 32 can rotate around its axis; the forward rotation and reverse rotation of the connecting rod 32 are relative concepts, and the specific rotation direction is not limited.
[0031] Specifically, when the telescopic arm is extended, the mounting seat 31 moves downward from the upper part of the connecting arm 1, and the connecting rod 32 follows the mounting seat 31 to move up and down so that the top of the connecting rod 32 slides up and down along the rotating guide groove 21. Through the setting of the rotating guide groove 21, the connecting rod 32 moves downward along the rotating guide groove 21, and the connecting rod 32 rotates forward around its axis by a certain angle. At this time, the rotation of the connecting rod 32 does not require an additional power source, which reduces the production cost and use cost of the telescopic arm, and realizes the rotation of the connecting rod 32 while the connecting rod 32 descends, thereby improving the working efficiency of the telescopic arm; in addition, when the telescopic arm is retracted, the connecting rod 32 moves upward along the rotating guide groove 21, and the connecting rod 32 rotates in the opposite direction around its axis by a certain angle to reset. When the connecting rod 32 rises and slides along the rotating guide groove 21, the connecting rod 32 rotates in the opposite direction to facilitate the reset of the connecting rod 32, thereby improving the recovery efficiency of the telescopic arm.
[0032] Furthermore, if Figure 1 、 Figure 2 、 Figure 4 As shown, a torsion shaft 321 adapted to the rotation guide groove 21 is provided on the top of the connecting rod 32; the torsion shaft 321 slides along the torsion track in the rotation guide groove 21 to drive the connecting rod 32 to rotate forward or reverse.
[0033] Furthermore, if Figure 1 、 Figure 4 As shown, the mounting seat 31 is slidably mounted on the connecting arm 1, and the connecting arm 1 is equipped with a telescopic drive 5, and the output end of the telescopic drive 5 is connected to the mounting seat 31 to drive the mounting seat 31 to move back and forth up and down; specifically, the connecting arm 1 has a slide rail, and the mounting seat 31 has a slider adapted to the slide rail, and the stable sliding of the mounting seat 31 is achieved by the cooperation of the slide rail and the slider; wherein the telescopic drive 5 can also be any one of an electric telescopic rod, an air cylinder, an oil cylinder or a winch structure; it can be understood that the mounting seat 31 and the connecting arm 1 can also adopt other cooperation methods, as long as the sliding of the mounting seat 31 can be achieved and the mounting seat 31 will not be detached from the connecting arm 1, and the telescopic drive 5 can also adopt other forms, as long as it can achieve the driving of the mounting seat 31 to slide, and there is no specific limitation.
[0034] Furthermore, if Figure 1 、 Figure 4 As shown, a stabilizer 7 is installed at the bottom of the connecting arm 1. Since the connecting rod 32 of the partial telescopic arm is long, the stabilizer 7 is provided to limit the connecting rod 32 at the bottom to ensure the verticality of the connecting rod 32, thereby ensuring the accuracy of the operation of the actuator 8 installed at the end of the connecting rod 32.
[0035] Furthermore, if Figure 1 、 Figure 4As shown, an external component 6 is provided at the bottom of the connecting rod 32, and the external component 6 is connected to the actuator 8; wherein, the actuator 8 can be a manipulator, a clamp, etc., which is not specifically limited and can be selected according to actual needs; the specific form of the external component 6 is not limited, as long as it can realize the connection between the connecting rod 32 and the actuator 8; in addition, the execution end recorded in the utility model refers to the bottom end of the connecting rod 32.
[0036] Example 2
[0037] The same parts as those in the first embodiment are given the same reference numerals and the same text descriptions are omitted. Compared with the first embodiment, the telescopic arm for performing the automatic reset of the end rotation provided in the present embodiment has the following different structural designs: Figure 1 and Figure 3 As shown, the rotary adjustment member 4 is also included, and the rotary adjustment member 4 locks or unlocks the rotation state of the connecting rod 32; by setting the rotary adjustment member 4, the state of the connecting rod 32 is changed. When the connecting rod 32 needs to rotate, the rotary adjustment member 4 unlocks the connecting rod 32, and when the connecting rod 32 does not need to rotate, the rotary adjustment member 4 locks the connecting rod 32. Specifically, Figure 1 and Figure 3 As shown, the rotation adjustment member 4 includes an adjustment limit plate 41 installed on the mounting seat 31 and a limit block 42 installed on the connecting rod 32. The adjustment limit plate 41 is provided with a limit hole 411, and the limit block 42 is provided with a limit member 43 that is at least partially adapted to the limit hole 411. The limit member 43 can be inserted into the limit hole 411 to realize rotation locking of the connecting rod 32, and the limit member 43 can be withdrawn from the limit hole 411 to realize rotation unlocking of the connecting rod 32; the rotation locking and rotation unlocking of the connecting rod 32 are realized by the cooperation between the limit hole 411 and the limit member 43; when the connecting rod 32 moves down and slides out of the rotation guide groove 21, the limit member 43 is inserted into the limit hole 411 to realize rotation locking of the connecting rod 32, and when the connecting rod 32 moves up and slides into the rotation guide groove 21, the limit member 43 withdraws from the limit hole 411 to realize rotation unlocking of the connecting rod 32, so as to ensure that the connecting rod 32 can rotate and move upward in the rotation guide groove 21.
[0038] More specifically, if Figure 3As shown, the limit block 42 is slidably installed on the connecting rod 32, and a sliding power source 44 is provided between the end of the limit block 42 away from the adjustment limit plate 41 and the connecting rod 32. The sliding power source 44 drives the limit block 42 to slide in the direction close to or away from the adjustment limit plate 41 to achieve rotational locking or unlocking of the connecting rod 32; when the connecting rod 32 moves down and slides out of the rotation guide groove 21, the sliding power source 44 drives the limit block 42 to slide in the direction close to the adjustment limit plate 41, and the limit member 43 is inserted into the limit hole 411 to achieve rotational locking of the connecting rod 32; in addition, when the connecting rod 32 moves up and slides into the rotation guide groove 21, the sliding power source 44 drives the limit block 42 to slide in the direction away from the adjustment limit plate 41, and the limit member 43 exits the limit hole 411 to achieve rotational unlocking of the connecting rod 32.
[0039] Furthermore, if Figure 1 and Figure 3 As shown, the sliding power source 44 adopts a compression spring. When the connecting rod 32 is in the rotating guide groove 21, the compression spring is in a compressed state and the top of the limit member 43 contacts the adjustment limit plate 41. When the connecting rod 32 slides downward in the rotating guide groove 21, the limit block 42 rotates with the connecting rod 32. When the connecting rod 32 moves downward and slides out of the rotating guide groove 21, the limit member 43 is aligned with the limit hole 411. At this time, the compression spring resets and drives the limit block 42 and the limit member 43 toward the direction close to the adjustment limit plate 41. The limiting member 43 slides into the limiting hole 411, thereby locking the rotation of the connecting rod 32. Furthermore, as the connecting rod 32 moves upward and slides into the rotation guide groove 21, the portion of the connecting rod 32 that engages the rotation guide groove 21 (the torsion axis 321) strikes the rotation guide groove 21. This forces the connecting rod 32 downward, and the compression spring is compressed, driving the limiting member 43 out of the limiting hole 411, thereby unlocking the rotation of the connecting rod 32. Simultaneously, the telescopic drive 5 drives the connecting rod 32 to continue moving upward along the rotation guide groove 21, thereby resetting the connecting rod 32. It is understood that the sliding power source 44 may also take other forms, specifically, an electric telescopic rod, a pneumatic cylinder, or an oil cylinder.
[0040] Furthermore, a roller 431 is provided at the end of the limiting member 43 facing the adjustment limiting plate 41, and the roller 431 is adapted to the limiting hole 411. By providing the roller 431, when the top of the limiting member 43 contacts the adjustment limiting plate 41, the friction force is reduced, thereby ensuring that the limiting block 42 rotates normally following the connecting rod 32.
[0041] As an implementation method, the roller 431 is a roller or a ball.
[0042] Example 3
[0043] The same parts in this embodiment as those in the first and second embodiments are given the same reference numerals, and the same textual descriptions are omitted.
[0044] Compared with Example 1 and Example 2, the telescopic arm for performing automatic resetting of the end rotation provided in this embodiment has the following different structural design: the limit member 43 is slidably installed on the limit block 42, and a sliding power source 44 is provided between the end of the limit member 43 away from the adjustment limit plate 41 and the limit block 42. The sliding power source 44 drives the limit member 43 to slide toward or away from the adjustment limit plate 41 to achieve rotational locking or unlocking of the connecting rod 32; in this embodiment, the limit block 42 is fixedly installed on the connecting rod 32, and the limit member 43 can move up and down relative to the limit block 42. The cooperation principle of the limit member 43 and the limit hole 411 in this embodiment is basically the same as that in Example 2, and will not be repeated here.
[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
