Description

Technical Field

[0001] The utility model relates to a display lifting bracket. Background Art

[0002] Currently, monitors on the market are generally provided with a lifting bracket, through which the monitor can be placed on a desktop, and the height of the monitor can be adjusted according to the user's habits, thereby meeting the user's viewing needs.

[0034] The left side wall of the lifting seat 20 is provided with a first wear-resistant part 22 and a second wear-resistant part 23 distributed in the up-down direction, and the right side wall of the lifting seat 20 is provided with a third wear-resistant part 24 and a fourth wear-resistant part (not shown) distributed in the up-down direction. The first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are formed with a plurality of convex ribs 221 arranged at intervals in the front-to-back direction on the surface of the side away from the lifting seat 20. The convex ribs 221 extend in the up-down direction, and the surface of the side of the convex rib 221 away from the lifting seat 20 is in sliding contact with the inner wall of the activity space 11.

By adopting nylon, the first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part all have a low friction coefficient and good self-lubricating property, so that the lifting seat 20 can be prevented from shaking left and right during the up and down movement, and the up and down movement of the lifting seat 20 can be provided with better smoothness and stability.

[0036] The first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are all connected to the lifting seat 20 by screws 25; by adopting the screw 25 connection method, the lifting seat 20, the first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are all arranged in a split type, so that the first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part can be arranged to have the same structure and formed in the same set of molds, which is easy to produce, and the lifting seat 20 can be formed of metal material to improve strength.

[0039] The first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are all rectangular wear-resistant sheets, and the surface of the rectangular wear-resistant sheet close to the lifting seat 20 is in contact with the surface of the lifting seat 20; by adopting the rectangular wear-resistant sheet, the surface of the rectangular wear-resistant sheet close to the lifting seat 20 is in contact with the surface of the lifting seat 20, so that the contact area between the rectangular wear-resistant sheet and the lifting seat 20 is maximized, thereby making the assembly of the rectangular wear-resistant sheet and the lifting seat 20 more stable, and improving the stability of the up and down sliding of the lifting seat 20.

[0040] The width of the rib 221 along the front-to-back direction is 0.7mm-1.0mm, preferably the width of the rib 221 along the front-to-back direction is 0.8mm, the height of the rib 221 protruding along the left-right direction is 0.4mm-0.6mm, preferably the height of the rib 221 protruding along the left-right direction is 0.5mm.

The inner slide rail 131 is mounted on the lifting seat 20 , and the outer slide rail 132 is mounted on the bracket body 10 .

[0042] The rear end of the lifting seat 20 is provided with a constant force spring 26, the lifting seat 20 and the bracket body 10 are connected to the constant force spring 26, the first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are all arranged between the slide rail assembly 13 and the constant force spring 26, specifically, the number of the constant force springs 26 is two, the two constant force springs 26 are distributed in the up and down directions, and the constant force spring 26 can enable the lifting seat 20 to stay at any height position, wherein the constant force spring 26 adopts a coil spring; by The first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are all arranged between the slide rail assembly 13 and the fixed force spring 26. The slide rail assembly 13 provides support for the front end of the lifting seat 20, and the fixed force spring 26 provides support for the rear end of the lifting seat 20. The first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part provide support for the left and right sides of the lifting seat 20.

[0043] In summary, the utility model arranges the first wear-resistant part 22 and the second wear-resistant part 23 distributed in the up-down direction on the left side wall of the lifting seat 20, and arranges the third wear-resistant part 24 and the fourth wear-resistant part distributed in the up-down direction on the right side wall of the lifting seat 20. The first wear-resistant part 22, the second wear-resistant part 23, the third wear-resistant part 24 and the fourth wear-resistant part are formed with a plurality of convex ribs 221 arranged at intervals along the front-to-back direction on the side surface away from the lifting seat 20. During assembly, the side surface of the convex rib 221 away from the lifting seat 20 slides and abuts against the inner side wall of the activity space 11 on the bracket body 10, which can play an auxiliary positioning effect on the lifting seat 20, thereby preventing the lifting seat 20 from shaking left and right, and the lifting seat 20 has better stability. In addition, the multiple convex ribs 221 on the same wear-resistant part are arranged in a spaced distribution, so that each wear-resistant part has a plurality of contact points with the bracket body 10, which has a better auxiliary positioning effect, can also reduce the material used for the wear-resistant part, and reduce the material cost.
