Background

The common essential article such as table chair that arrive among the daily life now also often meets the condition that needs adjust table chair height in office space or in teaching lecture hall, for example on the lecture hall, the teacher is different with student's height, the height of table needs to be adjusted to different heights, or when business office, the demonstration board need realize being similar to in the use of projection show, need adjust the demonstration board to appointed height, descend again under the condition of not using and retract to minimum height, reduce occupation space. However, most of the lifting systems in the market are of hollow screw rod type structures, the lifting adjusting speed is slow, and the screw rod processing cost is high.

Disclosure of Invention

The utility model discloses the purpose: in order to solve the problem that a traditional desk and chair cannot automatically adjust the lifting height, the hollow screw type structure is adopted to increase the manufacturing cost, and the height adjusting speed is slow, a rack type electric office lifting desk is designed, a lifting mechanism of a rack and gear transmission assembly is adopted, the hollow screw type transmission structure is abandoned, the adjusting speed is accelerated, the perforated slotted structure cannot be seen in the appearance, the rack is attractive and simple, the machining difficulty is greatly reduced by using a bendable rack instead of adopting a screw rod structure, also heavier parts such as a motor can be fixed on the inner wall of an outer barrel, the design is not allowed on the inner barrel, the lifting weight and the manufacturing cost are also reduced, and the rack type electric office lifting desk is practical and convenient.

The technical scheme adopted for solving the problems is as follows:

a rack type electric office lifting table comprises a table top and lifting table legs, wherein the table legs comprise an outer cylinder, an inner cylinder and a gear and gear transmission component,

the bottom of the outer barrel is provided with a base, the inner side wall is also vertically provided with a rack, the periphery of the inner barrel is provided with a chute, the inner wall is fixedly connected with one end of the rack through a connecting piece, the other end of the rack is freely placed in the chute, a longer part of the rack slides up and down in the chute, the periphery of the inner barrel is also fixedly connected with a sliding ferrule in a sleeved mode and matched with the sliding ferrule arranged on the inner wall of the outer barrel to fill a gap between the inner barrel and the outer barrel, so that the sliding is smooth, and,

the inner cylinder lower part is seted up the mounting groove for dodging motor and urceolus and passing through the bolt spiro union fixedly, the gear meshes the reduction gearing with the drive gear of motor, the motor links firmly in the urceolus lower part.

Furthermore, the upper end of the inner cylinder is provided with a top cover for dust prevention, and a motor wire hole is formed, so that the motor is electrically connected with the brake control box.

Furthermore, a sliding ferrule sleeved on the inner cylinder is also provided with a groove tightly attached to the sliding groove and used for avoiding the rack.

Furthermore, the rack can be bent towards one side of the teeth in a one-way mode, the periphery of the gear meshing transmission position is tightly attached with a roller, and the roller is fixedly connected to the inner wall of the outer barrel through a connecting shaft.

The utility model has the advantages that:

this electronic official working lift table of rack formula adopts rack and pinion drive assembly's elevating system, abandons cavity screw transmission structure for governing speed, and the trompil fluting structure can not be seen to the outward appearance, and is pleasing to the eye brief, changes to the rack that can buckle and does not adopt the lead screw structure also to reduce the processing degree of difficulty greatly, also can make heavier parts such as motor fix at the urceolus inner wall, and need not design on the inner tube, has also reduced lift weight and manufacturing cost, and is practical convenient.
