Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1 - 4As shown in the figure, a slide rail assembly of a combined counter includes a mounting bracket 1. A slider assembly 2 is provided on the mounting bracket 1. The slider assembly 2 includes a sliding block 21. Four bearings 23 are installed on the sliding block 21. A pipe is provided inside the sliding block 21 and is connected to the four bearings 23. A cam 24 is installed on the outer wall of the bearing 23. Two concave chutes 25 are respectively installed on the top surface and the bottom surface of the mounting bracket 1. The four cams 24 are respectively in contact with the two concave chutes 25. A limit block 22 is installed at the right end of the sliding block 21. A plug 5 is installed at the right end of the mounting bracket 1. The plug 5 is located on the movement track of the limit block 22. When the sliding block 21 is displaced by an external force, the sliding block 21 drives the four bearings 23 to move. The four bearings 23 respectively drive the four cams 24 to roll on the two concave chutes 25, so that the sliding block 21 slides on the concave chutes 25 on the mounting bracket 1 through the cooperation of the bearings 23 and the cams 24. Due to the horizontal limit relationship between the concave chutes 25 and the cams 24, the sliding block 21 will not shift horizontally when sliding on the mounting bracket 1. And due to the limiting effect of the plug 5 on the limit block 22, the sliding block 21 is prevented from detaching from the concave chutes 25. When it is necessary to disassemble the sliding block 21, after removing the plug 5, the sliding block 21 can be taken out. A lubrication assembly 3 is provided on the mounting bracket 1. The lubrication assembly 3 includes a housing 31. The housing 31 is installed at the left end of the mounting bracket 1. An oil storage tank 32 is installed inside the housing 31. A refueling pipe 33 is installed inside the oil storage tank 32. An oil injection port 36 is installed on the sliding block 21. The oil injection port 36 is connected to the pipe inside the sliding block 21. A silicone valve 34 is provided on the inner wall of the refueling pipe 33. The silicone valve 34 is located on the movement track of the oil injection port 36. An inflation block 35 is installed on the housing 31. An air pipe is provided inside the inflation block 35 and is connected to the oil storage tank 32. The inflation block 35 is located on the movement track of the sliding block 21. An inflation block 35 is installed on the housing 31. An air pipe is provided inside the inflation block 35 and is connected to the oil storage tank 32. The inflation block 35 is located on the movement track of the sliding block 21. When the sliding block 21 moves towards the housing 31, the sliding block 21 drives the oil injection port 36 to move towards the direction close to the refueling pipe 33, so that the oil injection port 36 is inserted into the refueling pipe 33. When the oil injection port 36 is inserted into the refueling pipe 33, the oil injection port 36 contacts the silicone valve 34 and pushes the silicone valve 34 open. While the sliding block 21 moves towards the housing 31, the sliding block 21 contacts the inflation block 35 and squeezes the inflation block 35, so that the inflation block 35 fills a small amount of air into the oil storage tank 32 through the air pipe inside it. The oil storage tank 32 adds the lubricant inside it to the oil injection port 36 through positive pressure action. When the oil injection port 36 is not in contact with the refueling pipe 33, the silicone valve 34 closes to prevent the lubricant from flowing out of the refueling pipe 33.

[0026] In this embodiment, through the cooperation of the cam 24 and the concave chute 25, the two concave chutes 25 limit the sliding block 21 through four cams 24, enabling the sliding block 21 to only slide in the direction parallel to the mounting frame 1, avoiding the detachment or dislocation of the sliding block 21 after long-term use; through the setting of the lubrication assembly 3, every time the sliding block 21 makes a reciprocating motion, the oil storage chamber 32 will add lubricant into the oil injection port 36 through the oil filling pipe 33, and the oil injection port 36 replenishes the lubricant to the four bearings 23, thereby realizing the function of replenishing the lubricant to the bearings 23, avoiding the reduction of the rolling effect of the bearings 23 due to excessive loss of the lubricant in the bearings 23 after long-term use, and further affecting the sliding effect of the sliding block 21.

[0027] Embodiment 2

[0028] Please refer to Figure 5 As shown, a cleaning assembly 4 is provided on the sliding block 21. The cleaning assembly 4 includes four rotating shafts 41. The four rotating shafts 41 are all rotatably installed on the sliding block 21. The rear end of the rotating shaft 41 is connected with a friction wheel 42. A roller brush 43 is installed on the outer wall of the rotating shaft 41. Two friction strips 44 are respectively installed on the top and bottom surfaces of the sliding block 21. The two friction strips 44 are respectively in contact with the four friction wheels 42. The four roller brushes 43 are all in contact with the mounting frame 1 and the two concave chutes 25. When the sliding block 21 moves, the sliding block 21 drives the four rotating shafts 41 to move, and the four rotating shafts 41 drive the four friction wheels 42 to move. The friction wheels 42 rotate due to the friction with the friction strips 44 during the movement, so that the four friction wheels 42 drive the four rotating shafts 41 to rotate during the horizontal movement, and the four rotating shafts 41 drive the four roller brushes 43 to rotate. The roller brushes 43 clean the surfaces of the mounting frame 1 and the two concave chutes 25 through rotation.

[0029] In this embodiment, through the setting of the cleaning assembly 4, when the sliding block 21 slides on the two concave chutes 25, the four roller brushes 43 can continuously clean the two concave chutes 25 and the mounting frame 1 through rotation, avoiding a large amount of dust or oil stains adhering to the mounting frame 1 and the concave chutes 25 after long-term use, resulting in affecting the sliding of the sliding block 21.

[0030] When the sliding rail assembly of the combined counter of the present utility model is in use, when the sliding block 21 is displaced by an external force, the sliding block 21 drives the four bearings 23 to move. The four bearings 23 respectively drive the four cams 24 to roll on the two concave chutes 25, so that the sliding block 21 slides on the concave chute 25 on the mounting frame 1 through the cooperation of the bearing 23 and the cam 24. Due to the horizontal limiting relationship between the concave chute 25 and the cam 24, the sliding block 21 will not shift horizontally when sliding on the mounting frame 1. And due to the limiting effect of the plug 5 on the limiting block 22, the sliding block 21 is prevented from disengaging from the concave chute 25. When the sliding block 21 needs to be disassembled, after removing the plug 5, the sliding block 21 can be taken out. Through the cooperation of the cam 24 and the concave chute 25, the two concave chutes 25 limit the sliding block 21 through the four cams 24, so that the sliding block 21 can only slide in the direction parallel to the mounting frame 1, avoiding the sliding block 21 falling off or being misaligned after long-term use; when the sliding block 21 moves towards the housing 31, the sliding block 21 drives the oil injection port 36 to move towards the direction close to the oil filling pipe 33, so that the oil injection port 36 is inserted into the oil filling pipe 33. When the oil injection port 36 is inserted into the oil filling pipe 33, the oil injection port 36 contacts the silica gel valve 34 and pushes the silica gel valve 34 open. While the sliding block 21 moves towards the housing 31, the sliding block 21 contacts the inflation block 35 and squeezes the inflation block 35, so that the inflation block 35 fills a small amount of air into the oil storage 32 through the trachea inside it. The oil storage 32 adds the lubricant inside it to the oil injection port 36 through the oil filling pipe 33 under the positive pressure effect. When the oil injection port 36 does not contact the oil filling pipe 33, the silica gel valve 34 closes to prevent the lubricant from flowing out of the oil filling pipe 33; through the setting of the lubrication assembly 3, every time the sliding block 21 makes a reciprocating movement, the oil storage 32 will add the lubricant to the oil injection port 36 through the oil filling pipe 33, and the oil injection port 36 replenishes the lubricant to the four bearings 23, thus realizing the function of replenishing the lubricant to the bearings 23, avoiding that after long-term use, the lubricant loss in the bearings 23 is relatively large, resulting in the reduction of the rolling effect of the bearings 23, and further affecting the sliding effect of the sliding block 21; when the sliding block 21 moves, the sliding block 21 drives the four rotating shafts 41 to move, and the four rotating shafts 41 drive the four friction wheels 42 to move. The friction wheels 42 rotate by friction with the friction strips 44 during the movement, so that the four friction wheels 42 will drive the four rotating shafts 41 to rotate during the horizontal movement. The four rotating shafts 41 drive the four roller brushes 43 to rotate, and the roller brushes 43 clean the surfaces of the mounting frame 1 and the two concave chutes 25 by rotating. Through the setting of the cleaning assembly 4, when the sliding block 21 slides on the two concave chutes 25, the four roller brushes 43 can continuously clean the two concave chutes 25 and the mounting frame 1 by rotating, avoiding that after long-term use, a large amount of dust or oil stains adhere to the mounting frame 1 and the concave chutes 25, resulting in the influence on the sliding of the sliding block 21.

Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the embodiments of the present invention.
