Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Example 1: An easily adjustable office chair, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a mounting base 1, a rotating rod 2, a fixing block 3, a first mounting frame 4, a first pin 5, and a light-shielding component. The upper part of the mounting base 1 is covered with a soft pad, and the first mounting frame 4 is covered with a rubber sleeve to improve the comfort of people sitting on the first mounting frame 4. Fixing blocks 3 are welded to the left and right sides of the upper part of the mounting base 1. The rotating rod 2 is installed between the fixing blocks 3 through bearings. Multiple slots 6 are evenly opened on the right fixing block 3. The rotating rod 2 has an opening on the right side, and the opening of the rotating rod 2 corresponds to one of the slots 6. The first pin 5 is inserted into the right part of the rotating rod 2. The first pin 5 is inserted into the corresponding slot 6 through the opening on the rotating rod 2. The first mounting frame 4 is fixed to the upper part of the rotating rod 2. The first mounting frame 4 is provided with a light-shielding component.
[0028] like Figure 1 , Figure 10 , Figure 11 and Figure 12 As shown, the light-blocking assembly includes a second mounting bracket 18, a fixing bracket 19, a fixing rod 1901, and a light-blocking curtain 20. The fixing rods 1901 are fixedly connected to the left and right sides of the middle of the first mounting bracket 4. The fixing bracket 19 is welded between the upper parts of the fixing rods 1901. The second mounting bracket 18 is installed between the fixing rods 1901 through bearings. The light-blocking curtain 20 is fixedly connected between the second mounting bracket 18 and the fixing bracket 19.
[0029] Initially, the second mounting bracket 18 is secured to the fixed bracket 19, and the blind curtain 20 is in the retracted state. When people want to work or rest, they can use this device. First, pull out the first pin 5, push and pull the first mounting bracket 4. The first mounting bracket 4 rotates, causing the rotating rod 2 to rotate. Then, adjust the first mounting bracket 4 to a comfortable angle, so that the slot 6 on the fixed block 3 corresponds to the opening of the rotating rod 2, and insert the first pin 5 between the fixed block 3 and the rotating rod 2 to fix the first mounting bracket 4. By adjusting the first mounting bracket 4 to a comfortable angle, the comfort of people working or resting can be improved. When people want to rest in a low-light environment, rotate the second mounting bracket 18 downwards. The blind curtain 20 unfolds with the rotation of the second mounting bracket 18, providing a light-blocking function for people to rest better. When it is necessary to retract the blind curtain 20, push the second mounting bracket 18 upwards to reset it. The rotation of the second mounting bracket 18 causes the blind curtain 20 to retract, preventing the light-blocking curtain from affecting people's work.
[0030] Example 2: Based on Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, it also includes a movable block 7 and a second pin 8. There are two movable blocks 7, which are slidably connected to the left and right sides of the front of the first mounting frame 4. Multiple grooves are opened on the side of the movable blocks 7 that is far apart from each other. Openings are opened on the left and right sides of the front of the first mounting frame 4. Each opening of the first mounting frame 4 corresponds to a groove adjacent to a movable block 7. Second pins 8 are inserted into the left and right sides of the front of the first mounting frame 4. The second pins 8 pass through the opening of the first mounting frame 4 and are inserted into the corresponding groove of the movable block 7.
[0031] When people want to comfortably rest their elbows, they can pull out the second pins 8 on both sides, pull the movable block 7 back and forth to adjust the movable block 7 to a suitable length, align one of the grooves of the movable block 7 with the corresponding opening of the first mounting bracket 4, insert the second pins 8 on both sides to fix the movable blocks 7 on both sides. By adjusting the movable block 7 to a suitable length, it is convenient for people to rest their elbows, which helps to improve the comfort of people working or resting.
[0032] like Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, it also includes a headrest 9, a mounting ring 10, a connecting rod 11, a spring 12, a clamping block 13, a connecting block 14, a turntable 15, a limiting block 16, and a lead screw 17. The connecting block 14 is slidably connected to the upper part of the first mounting frame 4, and the limiting block 16 is slidably connected to the middle part of the connecting block 14. The lead screw 17 is threadedly connected to the upper part of the limiting block 16, and the front part of the lead screw 17 is rotatably connected to the connecting block 14. The turntable 15 is welded to the rear part of the lead screw 17. The headrest 9 is fixedly connected to the front part of the limiting block 16. Mounting rings 10 are welded to both the left and right sides of the rear part of the headrest 9. The connecting rods 11 are slidably connected inside the mounting rings 10. The clamping blocks 13 are connected between the rear sides of the connecting rods 11. The clamping blocks 13 are located behind the connecting blocks 14 and abut against the first mounting frame 4. Springs 12 are wound around the connecting rods 11. The front and rear ends of the springs 12 are fixedly connected to the connecting rods 11 and the mounting rings 10, respectively.
[0033] When people want to adjust the height of the pillow 9, they rotate the turntable 15, which drives the lead screw 17 to rotate. The rotation of the lead screw 17 drives the limit block 16 to move back and forth, and the limit block 16 drives the pillow 9 to move back and forth, thus adjusting the height of the pillow 9. This allows people to be in a more comfortable position for their heads, which is conducive to rest. When people want to move the pillow 9 up and down, they pull the clamping block 13 backward, which causes the connecting rod 11 to move backward and the spring 12 to be compressed. Then, the pillow 9, the connecting block 14, and the clamping block 13 move up and down. After the pillow is moved to the appropriate position, the clamping block 13 is released, and the spring 12 returns to its original position, causing the clamping block 13 to move forward and press against the first mounting bracket 4, thereby fixing the pillow 9. By adjusting the up and down position of the pillow 9, people can meet different needs for the position of the pillow 9, which helps to improve its applicability.
