Problems solved by technology

[0002] The transmission coordination mode of its underframe transmission mechanism of the existing compact racks is unreasonable, such as the structure of the transmission shaft of its transmission mechanism, because the compact racks are usually relatively long, the drive shaft is located in the middle, and the two ends of the compact rack are provided with walking wheel shafts, and the drive shaft If it extends from one end of the compact rack to the other end, the torque is too large and it is easy to change or break, so it is improved to use the master-slave mode to cooperate with the transmission
However, the existing driving and driven shafts are matched with the shaft sleeves of the traditional circular transmission shaft and the seamless steel pipe due to the transmission fit with the corresponding mating component shaft sleeves. This matching structure and the corresponding transmission mode are the most prominent The disadvantages are: during the operation of the compact rack, due to the small frictional force of the mutual contact, the transmission stability of the transmission shaft is poor, and the force of the hand is large, usually reaching more than 8N, and the operation time is long or the load is slightly larger. The coupling transmission shaft and the corresponding The shaft sleeve will slip and cause idling, which will cause the transmission to fail
Especially the welding method causes inconvenience to the overall installation of compact shelves and bookshelves
Furthermore, due to the problem of the transmission structure of the existing compact rack, its chain is prone to mopping the floor
Also results in short service life and poor operational reliability
And the connection of existing underframe and upright post is usually either welded, or it is fixedly connected with fastener from the outside of dense shelf, bookshelf, and its fastener of this structure stretches out dense shelf, the outside of bookshelf; Space, and then there is an impact on personnel safety
Especially the welding method causes inconvenience to the overall installation of compact shelves and bookshelves

Embodiment Construction

[0013] In order to further understand the technical solutions of the present invention, the present invention will be further described by the following embodiments in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the compact rack in this embodiment includes a transmission device, and also includes a column, a hanging plate 51, an underframe 1, and the like. Its upright column comprises cylinder 41, and its transmission device comprises each drive shaft that is arranged on the chassis 1 through corresponding bearing device etc., is connected with the walking wheel 10 on the corresponding drive shaft 2 and the corresponding sprocket wheel 4. Each transmission shaft is polygonal, that is, a polygonal transmission shaft whose cross-sectional shape is polygonal. The drive shaft in this example is a hexagonal prism drive shaft 2c.

[0015] Its sprocket wheel 4 and the center hole of walking wheel 10 are the polygonal axle hole 5 that cross-sectio...

Abstract

The invention discloses a compact shelving. The compact shelving comprises chain wheels, ground wheels, or comprises chain wheels, ground wheels, driving wheels and transmission shafts connected with the chain wheels and the ground wheels, or connected with the chain wheels, the ground wheels and the driving wheels. The chain wheels and the ground wheels, or the chain wheels, the ground wheels and the driving wheels are provided with polygon shaft holes connected with the corresponding transmission shafts. The chain wheels and the ground wheels, or the chain wheels, the ground wheels and the driving wheels are connected with the corresponding transmission shafts through the polygon shaft holes. The compact shelving transmission device has the advantages of simple assembling structure, rational and cooperative transmission structure, smooth and steady and reliable transmission movement and high transmission efficiency.
