DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Refer to the instruction manual Figure 1-5 The utility model provides a high-precision raceway grinding forklift axle, comprising a forklift axle body 1, wherein a protective component for enhancing protective performance is provided on the outside of the forklift axle body 1;

[0025] like Figure 1-5As shown, the protection component includes a reinforcement member 2 installed on the outside of the forklift shaft body 1, the rear end of the reinforcement member 2 is externally threadedly connected with a fixing ring 3, the front end of the reinforcement member 2 is externally sleeved with a movable ring 4, the movable ring 4 is provided with an adjusting ring 5 on the side away from the fixing ring 3, the adjusting ring 5 is sleeved on the outside of the reinforcement member 2, and the adjusting ring 5 is threadedly connected to the reinforcement member 2; a limiting member 6 is installed on the side of the adjusting ring 5 close to the movable ring 4, and a limiting ring groove 7 and a positioning ring groove 8 are provided on the side of the movable ring 4 corresponding to the limiting member 6. The end of the limit member 6 away from the adjusting ring 5 extends to the inside of the limit ring groove 7, and the end of the limit member 6 close to the positioning ring groove 8 is sleeved with a positioning member 9 on the outside, and the positioning member 9 is arranged inside the positioning ring groove 8; the side close to the fixed ring 3 and the movable ring 4 is provided with four card slots 10 distributed in a circular array, and a buffer plate 11 is provided between the two corresponding front and rear card slots 10, and the buffer plate 11 is installed with card plates 12 at both ends of the front and rear ends, and the card plate 12 is provided with a buffer component for mitigating impact on the outside of the end close to the card slot 10.

[0026] like Figure 4 and 5 As shown, the buffer assembly includes a fixing part 13 and a plurality of springs 14 installed inside the card slot 10. The plurality of springs 14 are all installed on the side of the fixing part 13 close to the card slot 10. The fixing part 13 is arranged on the side of the card plate 12 close to the card slot 10. Through the elasticity of the buffer plate 11, the buffer plate 11 supported by the fixing part 13 can be unloaded to avoid damage to the forklift axle body 1 caused by excessive impact. The plurality of springs 14 are evenly spaced and distributed. The spaced distribution of the plurality of springs 14 can provide multi-directional support to the fixing part 13, so as to better buffer the impact.

[0027] like Figure 4 As shown, the length of the fixing member 13 and the length of the card plate 12 are both smaller than the length of the card slot 10. By setting the length of the fixing member 13 and the length of the card plate 12 to be smaller than the length of the card slot 10, the fixing member 13 and the card plate 12 can move up and down inside the card slot 10, avoiding being too tightly fitted and unable to move up and down.

[0028] like Figure 1-3 As shown, a movable gap 15 is provided between two adjacent buffer plates 11 to provide space for the buffer plates 11 to move up and down. The movable gap 15 between the two adjacent movable plates allows the buffer plates 11 to move up and down, thereby preventing the buffer plates 11 from being unable to move up and down due to narrow space.

[0029] like Figure 1 , 2As shown in , 3 and 5, the outer portion of the adjusting ring 5 is processed with a plurality of anti-slip strips 16 distributed at intervals.

[0030] First, the staff installs the fixing ring 3 threadedly connected to the reinforcement member 2 to the outside of the rear end of the reinforcement member 2, and then sequentially installs the plurality of buffer plates 11, first inserting the clamping plate 12 at the rear end of the buffer plate 11 into the clamping groove 10 on the fixing ring 3, and making the clamping plate 12 located on the side of the fixing member 13 away from the spring 14;

[0031] Afterwards, the movable ring 4 and the adjusting ring 5 are sleeved on the outside of the front end of the reinforcement 2, and the clamping groove 10 on the movable ring 4 is sleeved on the outside of the clamping plate 12 at the front end of the buffer plate 11, so that the front end of the buffer plate 11 can be supported by the spring 14 and the fixing member 13 in the movable ring 4, and then the adjusting ring 5 threadedly connected with the reinforcement 2 is rotated, so that the buffer plate 11 can be closely contacted with the movable ring 4, and the movable ring 4 can also be fixed and limited, thereby achieving the effect of limiting support for the front and rear ends of the buffer plate 11, and then the buffer plate 11 supported by the spring 14 is used to relieve the force and buffer the external impact;

[0032] After long-term use, the staff rotates the adjustment ring 5 to drive the movable ring 4 to separate from the buffer plate 11, so that the buffer plate 11 is not restricted and is convenient for the staff to disassemble and replace. The overall structure is simple and the operation is convenient, which can improve the convenience of disassembling and replacing the buffer plate 11.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
