In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.

1-4, the utility model provides a height-adjustable frame, which comprises a metal frame 1 and a forklift body 11, wherein a glass baffle plate 2 is installed on one side of the metal frame 1 in a penetrating manner, two telescopic rods 9 are fixedly connected to the lower end of the metal frame 1 and near the front edge and the rear edge, a support column 10 is arranged at the bottom of each telescopic rod 9, two upper racks 3 are fixedly connected to the lower end of the metal frame 1 and near the front edge and the rear edge, gears 5 are meshed to one side of each upper rack 3, a lower rack 6 is meshed to the other side of each gear 5, a connecting rod 7 is arranged in the middle of each gear 5, and a wheel disc 8 is fixedly connected to one end of each connecting rod 7.

In the utility model, after the operator on the seat 12 is blocked by the goods on the fork of the forklift, the right hand can extend to slowly rotate the wheel disc 8 downwards, at the moment, the wheel disc 8 drives the connecting rod 7 to move anticlockwise so as to drive the two gears 5 to move anticlockwise, and the lower rack 6 is fixed on the forklift body 11, so that the gears 5 slowly rise while moving anticlockwise so as to drive the connecting rod 7 and the wheel disc 8 to rise together until the gear teeth of the gears 5 move to the position where the upper end of the lower rack 6 does not have the rack, and meanwhile, the gears 5 can drive the upper rack 3 to move upwards in the moving process so as to drive the metal frame 1 to move upwards, thereby completing the height adjustment of the forklift frame.

In embodiment 2, as shown in fig. 1-4, the outer sides of the lower rack 6 and the upper rack 3 are respectively provided with a limiting rod 4, the limiting rods 4 are in sliding connection with the upper rack 3, the bottoms of the four limiting rods 4 are fixedly connected with the top of a forklift body 11, the top of the forklift body 11 is provided with a seat 12, the upper ends of the seats 12 are respectively provided with a seat armrest 13 at positions on two sides of a backrest, the bottoms of two support columns 10 are fixedly connected with the top of the forklift body 11, the tops of the support columns 10 penetrate through holes, a rearview mirror 14 is arranged at the top of the metal frame 1 and close to the glass baffle 2, the distance between two adjacent limiting rods 4 is smaller than the diameter of the gear 5, the height of the limiting rods 4 is larger than the length of the upper rack 3, the bottoms of the telescopic rods 9 are positioned inside the support columns 10, and the telescopic rods 9 are in sliding connection with the support columns 10.

The effect that its whole embodiment reached is, after having improved the height, perhaps pass the door when fork truck needs to follow a workshop motion to another workshop, this moment needs to reduce fork truck's frame, operating personnel only need stretch out right hand slowly upwards rotate rim plate 8 can, the same reason, rim plate 8 drives connecting rod 7 and is clockwise motion this moment, and then drive two gears 5 and do clockwise motion, and lower rack 6 is fixed on fork truck automobile body 11, consequently, gear 5 also can slowly descend when doing clockwise motion, and then drive connecting rod 7 and rim plate 8 and descend to descend together, thereby make the frame move down, when the high motion of frame top is under the door head, operating personnel's hand can leave rim plate 8 and carry out other operations, there is frictional force between telescopic link 9 and the support column 10 this moment, go up rack 3 and gag lever post 4 between the frictional force, simultaneously, go up rack 3 and receive the holding power from gear 5, consequently, the frame is under frictional force and holding power and self gravity's effect, the effect, like this operating personnel just can make the hand carry out other operations, secondly, protect operating personnel's handrail and set up on 12 and set up on the frame and can reduce the weight of the seat on the frame, and the weight of the fork truck is reduced, and the operating personnel can receive the weight of the frame is reduced like and the time is reduced.

Working principle: when the height of the forklift frame needs to be adjusted by an operator on the seat 12, the right hand can be extended to slowly rotate the wheel disc 8 upwards or downwards, at the moment, the wheel disc 8 drives the connecting rod 7 to move clockwise or anticlockwise, and then drives the two gears 5 to move clockwise or anticlockwise, the lower rack 6 is fixed on the forklift body 11, so that the gears 5 slowly descend or ascend while moving clockwise or anticlockwise, and then drive the connecting rod 7 and the wheel disc 8 to descend or ascend together, and meanwhile, the gears 5 can drive the upper rack 3 to move upwards in the moving process, and then drive the metal frame 1 to move upwards until the metal frame 1 moves to a reasonable interval which is wanted by the operator, the operator does not rotate the wheel disc 8 any more, and at the moment, the frame is fixed at the current position under the action of friction force, supporting force and self gravity, and then the height adjustment of the forklift frame is completed.

The present utility model is not limited to the above-mentioned embodiments, and any equivalent embodiments which can be changed or modified by the technical content disclosed above can be applied to other fields, but any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical substance of the present utility model without departing from the technical content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
