DETAILED DESCRIPTION

[0028] The utility model will be further described in connection with the drawings and examples as follows: ​

[0029] Please refer to Figures 1-6 The utility model provides an office chair armrest with good pressure resistance, comprising an office chair seat 1, one side of the office chair seat 1 is fixed with an office chair back 2;

[0030] Specifically, the office chair seat 1 can support the hips and thighs of the user, providing a comfortable sitting posture, and the office chair back 2 is ergonomic to ensure good back support during use, helping the user to maintain the correct sitting posture and reduce fatigue caused by long hours of work.

[0031] Further, both sides of the office chair back 2 are fixedly connected with an armrest sleeve 3, and a fixed support rod 31 is fixedly connected between the armrest sleeve 3 and the office chair seat 1, and both sides of the fixed support rod 31 are fixedly connected with an inclined support plate 32 between the bottom wall of the armrest sleeve 3.

[0032] Specifically, the main function of the fixed support rod 31 is to provide stable support for the armrest sleeve 3, ensuring that the connection between the armrest sleeve 3 and the office chair seat 1 is firm and not prone to loosening, and the design of the inclined support plate 32 increases the stability of the armrest sleeve 3, which can better disperse the force on the armrest sleeve 3 through inclined support, improving the compression resistance of the entire armrest structure.

[0033] Further, one end of the armrest sleeve 3 is slidably connected with an armrest sleeve rod 4, and a plurality of screw holes 42 are equidistantly formed on the armrest sleeve rod 4, and both sides of the armrest sleeve 3 are provided with through holes corresponding to the screw holes 42.

[0034] Specifically, the function of the limiting slide block 41 is to limit or control the movement range of the armrest sleeve rod 4 in the armrest sleeve 3, ensuring that the armrest sleeve rod 4 does not move excessively or come out of the armrest sleeve 3 during adjustment, the screw holes 42 allow the user to fix the armrest sleeve rod 4 at different positions, thereby achieving multi-position adjustment of the armrest plate 44, and the through holes allow the bolts 48 to pass through the armrest sleeve 3 and threadedly engage with the screw holes 42 to fix the position of the armrest sleeve rod 4.

[0035] Further, one end of the armrest sleeve 3 is slidably connected with an armrest sleeve rod 4.

[0036] Specifically, the length of the armrest sleeve 3 is limited, and pulling out the armrest sleeve rod 4 can extend the support range of the armrest sleeve 3, which is suitable for people with different arm lengths and office habits.

[0037] Further, the upper side of the armrest sleeve rod 4 is fixed with a positioning block 43, the upper side of the positioning block 43 is fixedly connected with an armrest plate 44, one end of the armrest plate 44 is fixedly connected with a supporting block 45 on the lower side, and the supporting block 45 slides with the top wall of the armrest sleeve 3.

[0038] Specifically, the positioning block 43 serves to provide a fixed connection point for the armrest plate 44, ensuring that the armrest plate 44 can be stably connected to the armrest sleeve 4 and move together with the armrest sleeve 4. The armrest plate 44, which is the platform for the user's arm support, is connected to the armrest sleeve 4 through the positioning block 43. This design enables the armrest plate 44 to stably support the user's arm. The supporting block 45 serves to provide additional support for the armrest plate 44, ensuring its stability and load-bearing capacity during use. The sliding structure allows the armrest plate 44 to move forward and backward within a certain range, adapting to the needs of different users and providing more comfortable support.

[0039] Further, both sides of the end of the armrest plate 44 away from the armrest sleeve 3 are fixed with side guards 46. The outer sides of the side guards 46 are provided with limiting holes 47, and the limiting holes 47 are embedded with bolts 48. One end of the bolt 48 passes through the through hole and is screwed into the adjacent screw hole 42.

[0040] Specifically, the side guards 46 serve to protect the edges of the armrest plate 44, increase the stability of the structure, and also have an aesthetic effect, making the overall appearance of the office chair armrest more neat and harmonious. The limiting holes 47 are holes for fixing the bolts 48, which allow the bolts 48 to pass through and be embedded therein. By tightening or loosening the bolts 48, the user can adjust the extension length of the armrest plate 44 to adapt to the arm length and office habits of different users, thereby achieving multi-position adjustment of the armrest plate 44.

[0041] Further, the upper side of the armrest plate 44 is fixedly bonded with a soft cushion layer 49.

[0042] Specifically, the soft cushion layer 49 is usually made of soft materials such as foam, sponge, or memory foam, etc. These materials can absorb pressure and provide good tactile sensation and support. By fixedly bonding the soft cushion layer 49 on the upper side of the armrest plate 44, better support and comfort can be provided when the user's arm contacts the armrest, thereby improving the overall user experience of the office chair. This design takes into account ergonomics, aiming to improve user comfort and reduce physical discomfort that may be caused by long hours of work.

[0043] Further, the lower part of the armrest sleeve 4 and the office chair seat 1 are fixed with linear slide rails 5. The armrest sleeve 4 and the linear slide rails 5 are connected with a movable support assembly 6. The movable support assembly 6 includes a I-shaped slide block 61 that is in sliding connection with the linear slide rails 5. The I-shaped slide block 61 and the end of the armrest sleeve 4 away from the armrest sleeve 3 are fixedly connected with a movable support rod 62.

[0044] Specifically, the design of the I-shaped slider 61 enables it to move smoothly along the linear slide rail 5, which can generally bear a large load while maintaining stability and smoothness. The movable support rod 62 provides support when the armrest sleeve rod 4 moves along the linear slide rail 5, ensuring that the armrest plate 44 is well supported at any position. The combination of the I-shaped slider 61 and the movable support rod 62 provides stable support, maintaining the stability of the armrest plate 44 even when it is adjusted to different positions.

[0045] Further, the movable support rod 62 is provided in an inclined or arc-shaped structure.

[0046] Specifically, the movable support rod 62 can conduct the stress of the armrest sleeve rod 4 to the I-shaped slider 61, so that the I-shaped slider 61 can be misaligned with the end of the armrest sleeve rod 4 to prevent the movable support rod 62 from interfering with the user's leg movement, ensuring comfort.

[0047] Working principle: When in use, after unscrewing the bolt 48, the armrest plate 44 can be slid forward and backward, allowing the length of the armrest sleeve rod 4 to be adjusted to suit people of different arm lengths and office habits. After the armrest plate 44 is moved to the desired position, the bolt 48 is screwed into the threaded hole 42 through the limiting hole 47 and the through hole, which can position the armrest plate 44. During this process, the armrest plate 44 can be well supported at any position, effectively improving the compression resistance of the office chair armrest.
