Detailed Implementation

[0026] like Figures 1 to 7 As shown, an adjustable office handrail structure includes a support assembly 10, a handrail assembly 20, and an adjustment component 30. The adjustment component 30 is adjustablely connected between the support assembly 10 and the handrail assembly 20. In use, the adjustment component 30 can rotate left and right or swing upward on the support assembly 10 to adjust the angle of use. The handrail assembly 20 can slide back and forth or rotate 360 ​​degrees on the adjustment component 30 to adjust the angle of use, making it convenient for users to adjust according to their needs.

[0027] In a specific implementation, the support assembly 10 includes a handrail support 11, the upper part of which is provided with a rotary joint 111. The adjustment assembly 30 includes a rotary positioning seat 31, the middle of which is provided with a rotary through hole 311. The size of the rotary through hole 311 is larger than the size of the rotary joint 111. The rotary joint 111 is connected in the rotary through hole 311 and is connected to the rotary joint 111 by fasteners passing through the rotary through hole 311, so that the rotary positioning seat 31 can be rotatably adjusted and connected to the handrail support 11.

[0028] In practical implementation, the lower two sides of the rotary positioning seat 31 are symmetrically recessed with arc-shaped limiting grooves 312, and the upper two sides of the armrest bracket 11 are symmetrically connected with limiting components 112. The top of the limiting component 112 is provided with a limiting protrusion 113, and the inner side of the limiting groove 312 is uniformly recessed with a plurality of limiting recesses 313 that are adapted to the limiting protrusion 113. The limiting protrusion 113 and the limiting recess 313 are correspondingly limited and connected. When the rotary positioning seat 31 rotates around the rotary joint 111, the limiting protrusion 113 slides along the arc-shaped limiting groove 312. Whenever the limiting protrusion 113 enters a limiting recess 313, the rotating positioning seat 31 is locked in that position. When the user adjusts the angle, they can apply an appropriate rotational force to disengage the limiting protrusion 113 from the current limiting recess 313 and move it to the next recess, thus achieving gear switching. The uniform spacing of the limiting recesses ensures precise adjustment of each angle, allowing users to maintain a consistent angle setting during repeated use. The arc-shaped design ensures smooth sliding of the protrusion and provides a good locking effect, allowing users to quickly adjust to the commonly used angle without frequent trial and error. Furthermore, the armrest bracket 11 can be adjusted vertically in six positions for convenient height adjustment.

[0029] In practical implementation, the rotary positioning seat 31 is equipped with a tilting bracket 32. Inside the tilting bracket 32, a first tilting hinge fixing block 33, a second tilting hinge fixing block 34, and a third tilting hinge fixing block 35 are respectively installed. The first tilting hinge fixing block 33 and the second tilting hinge fixing block 34 are respectively connected to the left and right ends of the third tilting hinge fixing block 35. The rear portions of the first tilting hinge fixing block 33 and the second tilting hinge fixing block 34 are respectively provided with first mounting through portions 36. The rear inner sides of the tilting bracket 32 ​​are symmetrically provided with second mounting through portions 321. The first mounting through portions 36 and the second mounting through portions 321... The first and second tilt hinge fixing blocks 33, 34, and 35 are respectively installed in the tilt bracket 32. The first tilt hinge fixing block 33 has a first fixing through-hole 331 at its front, and the tilt bracket 32 ​​has a second fixing through-hole 322 at its front. The first fixing through-hole 331 and the second fixing through-hole 322 are correspondingly arranged and connected and fixed by fasteners passing through the first fixing through-hole 331 and the second fixing through-hole 322. The first tilt hinge fixing block 33 is more stably installed in the tilt bracket 32. The rotary positioning seat 31 has a mounting slot 314 in its middle. The lower part of the third tilt hinge fixing block 35 has a mounting joint 351. The mounting joint 351 is located in the mounting slot 314 and is fixedly connected to the mounting joint 351 by fasteners passing through the mounting slot 314 and the mounting joint 351, thereby fixing the third tilt hinge fixing block 35 to the rotary positioning seat 31. A movable through plate 315 is located on one side of the mounting slot 314. The movable through plate 315 is located on one side of the first tilt hinge fixing block 33 and is fixedly connected by fasteners passing through it. The movable through plate 315 is connected to the first tilt hinge fixing block 33 and the third tilt hinge fixing block 35, thereby connecting the first tilt hinge fixing block 33 and the second tilt hinge fixing block 34 to the third tilt hinge fixing block 35 and fixing them as a whole. In use, when the tilt bracket 32 ​​is pushed upward, the first tilt hinge fixing block 33 and the second tilt hinge fixing block 34 can tilt upward along the third tilt hinge fixing block 35, so that the tilt bracket 32 ​​can tilt and swing upward along the rotating positioning seat 31 to adjust the use angle of the handrail, realizing multi-directional and multi-angle adjustment of the handrail, which is convenient for users.

[0030] In specific implementation, the handrail assembly 20 includes a handrail mounting bracket 21. The handrail mounting bracket 21 has a recessed mounting groove 211.

The middle part of the rotating positioning block 23 has a first mounting through hole 231, and the middle part of the handrail connecting part 323 has a second mounting through hole 324. The first mounting through hole 231 and the second mounting through hole 324 correspond to each other and are connected by fasteners passing through the first mounting through hole 231 and the second mounting through hole 324, so that the handrail assembly 20 can be rotatably connected to the tilting bracket 32.

[0031] In practical implementation, the edge of the rotating positioning block 23 is uniformly recessed with several arc-shaped positioning slots 232. The two sides of the movable groove 221 are connected to the rotating positioning component 223. One end of the rotating positioning component 223 is provided with an arc-shaped positioning block 224. The positioning block 224 is correspondingly positioned and connected to the positioning slot 232. When the handrail assembly 20 rotates around the handrail connecting part 323, the positioning block 224 slides along several positioning slots 232, so that the positioning block 224 disengages from the current positioning slot 232 and moves to the next positioning slot 232, realizing gear switching, ensuring that the angle adjustment of each gear is accurate and convenient for users to adjust the angle.

[0032] In practical implementation, the bottom surface of the mounting groove 211 is provided with a sliding groove 212. The size of the sliding groove 212 is larger than the size of the handrail connecting part 323, so that the handrail assembly 20 can be slidably connected to the tilting bracket 32. The two side walls of the mounting groove 211 are evenly recessed with a plurality of arc-shaped sliding positioning grooves 213. The two sides of the movable positioning block 22 are respectively connected to sliding positioning parts 225, and one end of the sliding positioning part 225 is provided with an arc-shaped sliding positioning block 226. The sliding positioning block 226 is correspondingly positioned and connected to the sliding positioning groove 213. When the handrail assembly 20 is pushed forward or backward along the handrail connection part 323, the movable positioning block 22 slides between the mounting groove 211 and the sliding positioning block 226 slides along several sliding positioning grooves 213, so that the sliding positioning block 226 disengages from the current sliding positioning groove 213 and moves to the next sliding positioning groove 213, thereby enabling the handrail assembly 20 to achieve the effect of positioning and sliding adjustment.

[0033] In summary, the support assembly 10 includes a handrail support 11, the adjustment assembly 30 includes a rotating positioning seat 31, which is rotatably and adjustablely connected to the handrail support 11, and a tilting support 32 is movably connected to the rotating positioning seat 31.
