Description

Technical Field

[0001] The utility model relates to the technical field of guide rail structures, in particular to a drawer with a guide rail structure that prevents the drawer from sliding out. Background Art

[0002] Nowadays, linear guides are also called slide rails, linear guide rails, and linear slide rails. They are used in linear reciprocating motion occasions. They have higher rated loads than linear bearings and can bear a certain torque. They can achieve high-precision linear motion under high load conditions. They can be used in various intelligent products that require high precision to effectively reduce errors and run more stably.

[0003] Regarding the wear-resistant and silent ball guide rail disclosed in patent number CN202320709182.4, a sliding bracket is used to install steel balls, and a shock-absorbing and wear-resistant layer is arranged between the steel balls and the ball grooves to reduce vibration during transmission and improve wear resistance. A sound-absorbing layer is arranged between the steel balls. The sound-absorbing layer reduces the sound of friction between the steel balls during the sliding of the guide rail, thereby playing a noise reduction role, solving the problem of existing guide rails that require silent equipment to operate. The coating layer is used to reduce the collision noise between adjacent steel balls, and the shock-absorbing and wear-resistant layer can also play a shock-absorbing and noise-reducing role during sliding. The shock-absorbing and wear-resistant layer is a coating formed by a combination of ceramic particles and modified toughening resins. While ensuring stable transmission during transmission, it also reduces the noise generated by vibration.

[0004] However, most of the guide rail structures now will suffer varying degrees of damage as the use time increases, such as ball loss or hardware deformation, and if the user pulls the drawer open completely during use, it is very likely that the drawer will fall off the guide rail, which brings a lot of inconvenience to the use of the drawer; therefore, the existing needs are not met, and we have proposed a drawer with a guide rail structure that prevents the drawer from sliding out.
