Detailed implementation mode

[0025] The present invention will be further described below in conjunction with a specific invention.

[0026] Embodiment

[0027] As Figure 1-6 shown, it is a structural schematic diagram of an asymmetric slide rail conduction device in a preferred embodiment of the present invention. The slide rail conduction device in this embodiment is arranged in the slide rail. The slide rail includes a movable rail 10 and a middle rail 20. The movable rail 10 is slidably connected to the middle rail 20. An asymmetric slide rail conduction device 30 is arranged between the movable rail 10 and the middle rail 20. The asymmetric slide rail conduction device 30 is used to play a conduction role when the movable rail 10 and the middle rail 20 slide.

[0028] A sliding flange 11 is arranged on the movable rail 10. A rail groove 21 is formed on the middle rail 20. The movable rail 10 and the middle rail 20 are slidably connected through the cooperation of the sliding flange 11 and the rail groove 21. The movable rail 10 slides on the middle rail 20.

[0029] A movable rail stop 12 is arranged inside the movable rail 10. A middle rail stop 22 is arranged inside the middle rail 20. The cooperation of the movable rail stop 12 and the middle rail stop 22 prevents the movable rail 10 and the middle rail 20 from having an interference fit during sliding and getting separated.

[0030] The described asymmetric slide rail conduction device 30 includes a U-shaped frame 31, rollers 32, and balls 33. Asymmetric ball mounting grooves 311 are provided on both side frames of the U-shaped frame 31, and an asymmetric roller mounting groove 312 is provided at the upper end of the U-shaped frame 31. The roller 32 is installed in the roller mounting groove 312 and is rotatably connected to the inner wall of the roller mounting groove 312. The ball 33 is installed inside the ball mounting groove 311 and is rotatably connected to the ball mounting groove 311. The rollers 32 and balls 33 on the asymmetric slide rail conduction device 30 are designed with an asymmetric structure. Its advantages are to disperse the stress points and the self-adaptation of the slide rail groove surface. That is, when the production equipment malfunctions, due to the product structure and equipment reasons, at this time, the asymmetric rollers 32 self-compensate, that is, they each run on their respective surfaces. In addition, since the rollers 32 and balls 33 have a certain range of movement space in the grooves of the U-shaped frame 31, the U-shaped frame 31 can always be kept in one position, thereby making the movable rail 10 more stable. Similarly, when the cross-section of the roller 32 on the middle rail 20 is abnormal, the rollers 32 will self-adapt along the curved surface respectively, and the U-shaped frame 31 can also always be kept in one position. At the same time, since the gap between the U-shaped frame 31 and the movable rail 10 and the middle rail 20 is greater than the movement space of the rollers 32 and balls 33 in the U-shaped frame 31, no matter how the rollers 32 and balls 33 change, it can ensure that the U-shaped frame 31 floats between the movable rail 10 and the middle rail 20 without interference causing abnormal noise, thereby making the movable rail 10 more stable.

[0031] Small elastic rubber positions 34 and large elastic rubber positions 35 are provided at both ends of the U-shaped frame 31 of the described asymmetric slide rail conduction device 30. The small elastic rubber positions 34 and large elastic rubber positions 35 are elastic shock-absorbing rubbers that are longitudinally symmetric and transversely asymmetric. A small elastic rib position 341 is provided at the root of the small elastic rubber position 34, and a large elastic rib position 351 is provided at the root of the large elastic rubber position 35. The small elastic rib position 341 and the large elastic rib position 351 are fixedly connected to the central position of the U-shaped frame 31. When the movable rail 10 and the middle rail 20 run to the end of the stroke, the small elastic rubber position 34 can cooperate with the movable rail stop 12 to achieve the shock-absorbing effect, and the large elastic rubber position 35 will cooperate with the middle rail stop 22 to achieve the shock-absorbing effect. At the same time, since ribs are provided at the roots of the small elastic rubber position 34 and the large elastic rubber position 35, and each rib is connected to the central position of the U-shaped frame 31, the U-shaped frame 31 can generate a shock-absorbing effect when being strongly impacted without undergoing large-scale distortion. Due to the product structure, the movable rail stop 12 and the middle rail stop 22 can only be diagonally stressed, so only through force transmission can the U-shaped frame 31 be prevented from being distorted as much as possible.

[0032] In this embodiment, when the movable rail 10 and the middle rail 20 slide through the asymmetric slide rail conduction device 30, the asymmetric structural design of the rollers 32 and the balls 33 on the asymmetric slide rail conduction device 30 enables the movable rail 10 to slide more smoothly. There are small elastic rubber positions 34 and large elastic rubber positions 35 at both ends of the U-shaped frame 31. The small elastic rubber positions 34 and the large elastic rubber positions 35 are elastic shock-absorbing rubbers that are longitudinally symmetric and transversely asymmetric. Rib positions are provided at the roots of the small elastic rubber positions 34 and the large elastic rubber positions 35. By using each rib position in cooperation with the movable rail stop 12 and the middle rail stop 22 on the movable rail 10 and the middle rail 20, a good shock-absorbing effect can be achieved, ensuring the quality of the product. The structure of the present invention is simple and easy to operate, and has a certain practicality.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as falling within the protection scope determined by the claims submitted for the present invention.
