In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0027] Such as Figures 1-11As shown in the figure, a seat armrest according to a preferred embodiment of the present utility model includes an armrest plate 1, an armrest 2, a support rod 3, a connection block 4, and an unlocking rod 5. One end of the armrest 2 is installed at the top of the support rod 3. At the top of the other end of the armrest 2, there is a connection groove 21. On both sides of the connection groove 21, there are rotating shafts 22. At the bottom of the connection groove 21, there is an arc-shaped block 23 arranged around the axis of the rotating shaft 22. The arc-shaped block 23 is provided with an arc-shaped through groove 231 arranged along the outer circumference of the arc-shaped block 23. At the side of the arc-shaped through groove 231, there is a locking groove 232 communicated with the arc-shaped through groove 231. A plurality of locking grooves 232 are arranged along the outer circumference of the arc-shaped through groove 231. The connection block 4 is installed at the bottom of the armrest plate 1. The bottom of the connection block 4 is arranged in the connection groove 21, and the connection block 4 is rotatably connected to the rotating shaft 22. At the bottom of the connection block 4, there is an installation groove 41 corresponding to the position of the arc-shaped through groove 231. The top end of the unlocking rod 5 passes through the arc-shaped through groove 231 and is slidably matched with the installation groove 41. The unlocking rod 5 can rotate around the axis of the rotating shaft 22 together with the connection block 4. On the side of the unlocking rod 5, there is a locking block 51 matched with the locking groove 232.
[0028] The working principle of this embodiment is as follows: Under normal circumstances, the locking block 51 is inserted into one of the locking grooves 232. At this time, the locking block 51 cooperates with the locking groove 232, making it impossible for the unlocking rod 5, the connection block 4, and the armrest plate 1 to rotate around the axis of the rotating shaft 22, that is, the armrest plate 1 is in a locked state, preventing the armrest plate 1 from being accidentally adjusted and helping the armrest plate 1 to maintain its established position; when it is necessary to flip and adjust the armrest plate 1, slide the unlocking rod 5 in the direction close to the installation groove 41, so that the locking block 51 disengages from the locking groove 232. At this time, the armrest plate 1 is in an unlocked state. Rotate the unlocking rod 5, the connection block 4, and the armrest plate 1 around the axis of the rotating shaft 22, that is, flip and adjust the position of the armrest plate 1. At this time, the locking rod slides along the direction of the arc-shaped through groove 231. When the locking block 51 moves to a position corresponding to the locking groove 232, slide the locking rod in a position away from the installation groove 41, so that the locking block 51 is inserted into the locking groove 232. At this time, the armrest plate 1 returns to the locked state, completing the flipping adjustment of the armrest plate 1. After the armrest plate 1 is flipped and adjusted upward Figure 10 As shown in the figure, after the armrest plate 1 is flipped and adjusted downward Figure 11 As shown in the figure; the present utility model is easy to operate and has a stable structure.
[0029] Exemplarily, a limiting groove 42 is provided on the side of the connection block 4. The limiting groove 42 is arranged along the length direction of the unlocking rod 5. On the side of the unlocking rod 5, there is a limiting block 52 extending into the limiting groove 42. When the unlocking rod 5 slides, the limiting block 52 can move in the limiting groove 42. The setting of the limiting block 52 and the limiting groove 42 plays a role in limiting and can prevent the unlocking rod 5 from disengaging from the installation groove 41.
[0030] Exemplarily, a return spring 53 is provided between the top end of the unlocking rod 5 and the inner top of the mounting groove 41. When a force is applied to the unlocking rod 5 to cause the unlocking rod 5 to slide towards the mounting groove 41, the return spring 53 is in a compressed state, thereby generating an elastic force. When the force is removed, the unlocking rod 5 will return to its original position under the action of the elastic force of the return spring 53, which helps the armrest plate 1 to return to the locked state.
[0031] Exemplarily, the arc-shaped block 23 and the connecting groove 21 are integrally formed, which is convenient for production and manufacturing.
[0032] Exemplarily, an opening is provided at the bottom of the connecting groove 21, and the arc-shaped block 23 is detachably installed on the opening. The material of the arc-shaped block 23 can be different from that of the connecting block 4. The arc-shaped block 23 can select different materials according to different cost and strength requirements, such as: aluminum alloy, zinc alloy and plastic.
[0033] Exemplarily, a first connecting column 43 is provided at the top of the connecting block 4. The first connecting column 43 is fixedly connected to the connecting block 4, and the first connecting column 43 is rotatably connected to the armrest plate 1. The armrest plate 1 can rotate relative to the armrest 2 around the axis of the first connecting column 43, thereby adjusting the position of the armrest plate 1. Combined with the flipping adjustment, the adjustable range of the armrest plate 1 is relatively large.
[0034] Exemplarily, a second connecting column 31 is rotatably connected to the top of the support rod 3. The top of the second connecting column 31 is fixedly connected to the armrest 2. The armrest 2 can rotate relative to the support rod 3 together with the second connecting column 31, that is, the armrest plate 1 can rotate around the axis of the second connecting column 31, thereby being able to rotate and adjust the position of the armrest plate 1.
[0035] Exemplarily, a button block 54 is provided at the bottom of the unlocking rod 5. By pressing the button block 54, the unlocking rod 5 can be driven to slide, which is convenient for operation.
[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
