Detailed Description

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Those not described in detail in this specification are within the skill of the art. In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 5, the roller 42 type fork provided in this embodiment includes a fork back 1, a fork arm 2, a protection plate 3, and a roller group 4, a bottom end of the fork back 1 is connected to a left end of the fork arm 2, the protection plate 3 is provided on both sides of the fork arm 2, a plurality of roller groups 4 are provided between the protection plate 3 and the fork arm 2, a cavity 5 is provided inside a mounting plate 41 of the roller group 4, damping particles 6 are filled in the cavity 5, vibration mechanical energy is consumed by collision and friction energy consumption between the damping particles and between the damping particles and an inner wall of the cavity 5, and a dissipation effect of the damping particles is utilized, thereby playing a role of vibration and noise reduction, and having a good noise reduction effect. The filling rate of the damping particles 6 in this embodiment is 85%, and the specific filling rate and material of the damping particles 6, which are ceramic particles, are selected according to actual requirements.

Further, the top of yoke 2 is equipped with rubber pad 7, through the setting of rubber pad 7, plays anti-skidding effect on the one hand, and on the other hand avoids the damage that the goods caused to yoke 2.

Further, the roller group 4 includes two mounting plates 41, rollers 42 and bearings 43, the inner side wall of each mounting plate 41 is provided with a plurality of bearings 43, the bearings 43 on the two mounting plates 41 are arranged in front and back in an opposite manner, a roller 42 is arranged between every two bearings 43 arranged in an opposite manner, the rollers 42 are divided into an upper row and a lower row, the rollers 42 in each row are all multiple, and the rollers 42 in the upper row and the lower row are arranged in a staggered manner and are in close contact with each other to provide sufficient operation friction force.
