Embodiment Construction

[0027] The patent is further described below in conjunction with examples, and the present invention is not limited to the following examples.

[0028] A hand-operated transmission device for a compact shelf, comprising a hand-operated mechanism, a transmission mechanism, a braking mechanism, a locking mechanism and the like.

[0029] Such as figure 1 , image 3 Shown: The transmission mechanism mainly includes a rolling key type two-way automatic clutch mechanism, a brake transmission mechanism, and an upper brake lock mechanism. The transmission chain on the board is composed of two-way loose edge automatic tensioning mechanism and other parts. It includes a fixed hollow shaft, a hand wheel 1 set on the hollow shaft 7, a clutch outer ring installed in the hand wheel 1, an inner ring set on the hollow shaft, and a roller key installed between the two. 2 Use the function of self-weight to form a rolling key type two-way automatic clutch. In the static state, the rocker hand...

Abstract

A compact-shelving handle transmission device comprises a handle mechanism, a transmission mechanism, a brake mechanism and a locking mechanism. The handle mechanism comprises a hand wheel and a hand shank located on the hand wheel, the handle mechanism is connected with a transmission shaft, and the transmission shaft is connected with an input shaft of a compact-shelving chassis through the transmission mechanism. The compact-shelving handle transmission device further comprises a rolling-key type automatic bidirectional clutch mechanism which comprises an outer ring, an inner ring and a rolling key, wherein the inner ring is fixed at one end, close to the hand wheel, of the transmission shaft, the outer ring is located on the outer circle of the inner ring, an arc-shaped groove is formed on the inner circle of the outer ring, the middle of the arc-shaped groove is wide, two sides of the arc-shaped groove are narrow, and the rolling key is located inside the groove. The transmission mechanism is integrally installed on the hand wheel, transmission and control are realized through concentric shafts, and a transmission chain installed on a transmission board bidirectionally loosens an automatic tension mechanism and other components. The compact-shelving handle transmission device is compact in structure, beautiful in appearance, simple, reasonable, capable of achieving transmission easily and conveniently, and simple and convenient to operate, operates reliably and without noise, and has practicality and popularization value.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device for a rack hand. Background technique [0002] As known, compact racks are widely used in enterprises and institutions to preserve various archives, and generally include a hand-shaking mechanism, a transmission mechanism, a brake and a locking mechanism. In order to prevent the hand wheel from rotating when the compact rack is passively moved, the early compact racks are often equipped with a manual clutch mechanism. The disadvantage is that when using it, you need to press the handle with your hand to make the clutch engage and shake the handle at the same time, otherwise it will run idly. It is inconvenient to use. Now the more common use is an automatic decoupling clutch mechanism, which is equipped with two hooks symmetrically distributed on both sides of the center of rotation of the handwheel. One hook in the state will make a metal impact sound during each ...
