Problems solved by technology
Therefore, for some sliding slide rails, the drawer slide rails will cause particularly large wear and tear during the back and forth sliding process, especially after years of use, the sliding surface will produce a lot of wear and tear, resulting in gaps, which makes the drawer of the drawer Pull deformation, and even lead to poor pull of the drawer
In addition, due to the manufacturing process, due to the accumulation of tolerances on the assembled slide rails, the drawer will shake from side to side when pulled, which will affect the use experience of the drawer

Embodiment Construction
[0018] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.
[0019] like Figure 1 to Figure 3 As shown, it is a structural schematic diagram of the drawer preload slide rail provided by the present invention. The drawer preload slide rail includes an outer rail 10 and a middle rail assembly 20 disposed in the outer rail 10 . It is conceivable that the drawer preload slide rail also includes some other functional modules, such as inner rails, assembly screws, installation components, etc., which are known to those skilled in the art and will not be repeated here.
[0020] The outer rail 10 includes an outer rail body 11 and a slide groove 12 disposed on the outer rail body 11 . The outer rail body 11 can be made of metal or non-metal. The chute 12 includes a strip-shaped ac...

A drawer pre-tightening force sliding rail comprises an outer rail and a middle rail assembly. The outer rail comprises a sliding groove. The middle rail assembly comprises a sliding block, an abutting piece and a pre-tightening spring. The sliding block comprises a body, a sliding inserting block and a containing groove. The containing groove is formed in the body and the sliding inserting block.The abutting piece is contained in the containing groove and comprises an abutting part and a fixing part. The pre-tightening spring abuts against the interior of the abutting part and the interior of the containing groove so as to drive the abutting part of the abutting part to abut against the sliding groove. According to the drawer pre-tightening force sliding rail, the pre-tightening spring is arranged between the abutting part and the sliding block, so the abutting part abuts against the interior of the sliding groove all the time, the loss of the contact face caused by friction betweenthe sliding block and the outer rail can be made up, then the sliding block can abut against the outer rail tightly all the time, and the purpose of eliminating the gap is achieved.
Description
technical field [0001] The invention relates to the technical field of drawer slide rails, in particular to a drawer preload slide rail. Background technique [0002] In people's life, there are many places where drawer slide rails are used, such as drawers, sliding doors, etc. Such products need to return to their original positions after being opened. Therefore, for some sliding slide rails, the drawer slide rails will cause particularly large wear and tear during the back and forth sliding process, especially after years of use, the sliding surface will produce a lot of wear and tear, resulting in gaps, which makes the drawer of the drawer Pull deformation, and even lead to poor pull drawer. In addition, due to the manufacturing process, the accumulated tolerances of the assembled slide rails will cause the drawer to shake from side to side when pulled, which will affect the use experience of the drawer. Contents of the invention [0003] In view of this, the present ...
