In addition, the terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0022] As Figures 1-6As shown, the utility model discloses a seat armrest of partial overturning adjustment, including armrest plate 1 and mounting seat 2, armrest plate 1 includes the fixed seat 11 and movable seat 12 that are arranged in sequence along the transverse direction, the fixed faceplate is equipped with on the fixed seat 11, and the movable faceplate is equipped with on movable seat 12, the fixed seat 11 is installed at the top of mounting seat 2, and the transverse direction of fixed seat 11 is equipped with the connecting shaft 13 that is arranged along the longitudinal direction on one end, and the connecting shaft 13 is fixedly connected with fixed seat 11, and the end of connecting shaft 13 is rotatably connected with movable seat 12, that is, movable seat 12 can rotate around the axis of connecting shaft 13 relative to fixed seat 11, and the locking block 14 is fixed on connecting shaft 13, and the side of locking block 14 is equipped with multiple locking grooves 141 that are arranged around the axis of connecting shaft 13, and the locking rod 15 that can move along the transverse direction is installed in movable seat 12, and the locking rod 15 can rotate with movable seat 12, and the end of locking rod 15 close to fixed seat 11 is matched with one of locking grooves 141, and the button block 16 that can move along the transverse direction is connected with locking rod 15, and button block 16 extends outside movable seat 12 to push button block 16.

[0023] The working principle of the embodiment is as follows: when in use, the mounting seat 2 is fixedly installed on the seat; under normal circumstances, the locking rod 15 is embedded in one of the locking grooves 141, and under the cooperation of the locking rod 15 and the locking groove 141, the movable seat 12 cannot rotate, at this time, the movable seat 12 is in a locked state, which helps the movable seat 12 to remain in a predetermined position and prevents the movable seat 12 from being accidentally overturned and adjusted, and the armrest plate 1 cannot be partially overturned and adjusted; when it is needed to partially overturn and adjust the armrest plate 1, the button block 16 is pushed to make the locking rod 15 move along the transverse direction and separate from the locking groove 141, at this time, the movable seat 12 is in an unlocked state, and the locking rod 15 and the movable seat 12 can rotate around the axis of the connecting shaft 13 together, so that the partial overturning adjustment of the armrest plate 1 is realized; when the locking rod 15 is rotated to a position corresponding to another locking groove 141, the locking rod 15 is embedded in the locking groove 141 corresponding thereto, so that the movable seat 12 returns to the locked state; the utility model is simple to operate, stable in structure, and can realize the partial overturning adjustment of the armrest plate 1.

[0024] For example, the top of the movable seat 12 is provided with a positioning groove 121, the positioning groove 121 is arranged below the locking rod 15 and is in sliding cooperation with the locking rod 15, the locking rod 15 penetrates the positioning groove 121 along the transverse direction and cooperates with one of the locking grooves 141, and through the cooperation of the locking rod 15 and the positioning groove 121, the sliding of the locking rod 15 along the transverse direction is ensured, and the deviation of the locking rod 15 during movement is prevented, so that the locking rod 15 can be embedded in the locking groove 141 corresponding thereto.

[0025] For example, the top of the positioning groove 121 is provided with a limiting plate 122 to prevent the locking rod 15 from separating from the positioning groove 121 from the top of the positioning groove 121.

[0026] Exemplarily, the top of the movable seat 12 is provided with a transversely arranged mounting groove 123, and a positioning block 124 is slidably connected in the mounting groove 123. Through cooperation of the mounting groove 123 and the positioning block 124, the locking rod 15 can be ensured to move transversely. The positioning block 124 is fixedly connected with the locking rod 15. The key block 16 is arranged at the bottom of the movable seat 12 and is fixedly connected with the bottom of the positioning block 124 and the bottom of the mounting groove 123. It can be understood that the bottom of the mounting groove 123 is provided with an opening, the top of the key block 16 passes through the opening and is connected with the positioning block 124, and the top of the key block 16 can move transversely in the opening, so that the key block 16 can move transversely to make the locking rod 15 disengage from the locking groove 141.

[0027] Exemplarily, a return spring 125 is arranged between the end of the positioning block 124 away from the locking rod 15 and the end of the mounting groove 123 away from the locking rod 15. When unlocking, the key block 16 is pressed to make the locking rod 15 disengage from the locking groove 141. At this time, the positioning block 124 will move away from the locking block 14 along the transverse direction, so that the spring is compressed to generate elastic force. After the key block 16 is released, the locking rod 15 is helped to embed in the locking groove 141 under the action of the elastic force, that is, the movable seat 12 is helped to return to the locked state.

[0028] Exemplarily, the fixed seat 11 is provided with a sliding groove 111 arranged transversely, the bottom of the sliding groove 111 is provided with a transversely arranged through groove 112, a sliding seat 113 is slidably connected in the sliding groove 111, the sliding seat 113 is provided with a connecting block 114, the top of the mounting seat 2 is provided with a connecting column 21, the connecting column 21 passes through the through groove 112 and is fixedly connected with the bottom of the connecting block 114, and the connecting column 21 can move transversely in the through groove 112. When in use, since the mounting seat 2 is mounted and fixed on the seat, the fixed seat 11 will slide transversely relative to the sliding seat 113 by being pushed transversely, so that the transverse movement adjustment of the armrest plate 1 is realized.

[0029] Exemplarily, the bottom of the connecting block 114 is provided with a connecting boss 115 coaxially arranged with the connecting column 21, the sliding seat 113 is provided with a connecting hole 116 slidably matched with the connecting boss 115, and the connecting column 21 is fixedly connected with the connecting boss 115 through the through groove 112 and the connecting hole 116. That is, the fixed seat 11 and the sliding seat 113 can rotate (around the axis of the connecting column 21) relative to the connecting block 114, so that the rotation adjustment of the armrest plate 1 is realized.

[0030] Exemplarily, the chair armrest further comprises an armrest arm 3, the bottom of the mounting seat 2 is provided with a connecting part 22, and the top of the armrest arm 3 is rotationally connected with the connecting part 22. The rotation axis of the armrest arm 3 and the connecting arm is arranged along the longitudinal direction. That is, the fixed seat 11 and the mounting seat 2 can rotate relative to the armrest arm 3, so that the overall overturning adjustment of the armrest plate 1 is realized.

[0031] The above merely describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, and these improvements and replacements should also be considered as the protection scope of the present application.
