The invention provides a slide rail assembly structure. The slide rail assembly structure comprises a fixed slide rail and a moving slide rail which are matched mutually in a sliding mode. A holder is arranged between the fixed slide rail and the moving slide rail. At least four rolling parts are arranged on the upper side of the holder in a rolling mode, and at least four rolling parts are arranged on the lower side of the holder in a rolling mode. The moving slide rail slides on the fixed slide rail through the rolling parts. A front limiting part and a rear limiting part are arranged at the front end and the rear end of the fixed slide rail in a spaced mode. The front limiting part and/or the rear limiting part are/is detachably arranged on the fixed slide rail. The holder is arranged on the front limiting part and the rear limiting part in a limited mode. The moving slide rail is limited between the front limiting part and the rear limiting part in a sliding mode. By means of the improvement of the structure, the structure has the advantages of being simple, reasonable, excellent in performance, fast to assemble, low in manufacturing cost, easy to produce and realize, high in practicality, capable of being widely applied to home furnishing such as a furniture drawer, a chest and a clothes hanger or household electrical appliances such as a refrigerator, a smoke exhaust ventilator and a water heater, and wide in use range, the closing and opening process is stable and smooth, and little force is used.
