Double-support elastic driving type cable coiling block

Abstract

The invention discloses a double-support elastic driving type cable coiling block. The double-support elastic driving type cable coiling block comprises an electric fitting half shaft, a spring half shaft, a clockwork spring, a stand and a reel and is characterized in that a center shaft of the double-support elastic driving type cable coiling block comprises the electric fitting half shaft and the spring half shaft, and the electric fitting half shaft is arranged on an electric fitting side support along with an electric fitting side bearing block and a bearing; the spring half shaft is arranged on a spring side support along with a spring side bearing block and a bearing; the electric fitting half shaft and the spring half shaft are in rigidity connection; the reel is arranged on the center shaft formed through connection of the electric fitting half shaft and the spring half shaft; and the clockwork spring is arranged in the spring half shaft arranged in a coiling block body. Due to adoption of the double supports, the installing stability of the elastic driving type cable coiling block is high; the clockwork spring is arranged in the reel, the axial size is reduced, the installing space is saved, and accordingly the occupied installing space is small; and the reel is assembled and integrated, spot welding combination is adopted between a keel ring and the coiling block body, and accordingly the production cost is low.

Description

technical field [0001] The invention relates to a mobile energy supply device, in particular to an elastic force driven cable reel. technical background [0002] Most of the currently used elastic drive cable reels are installed with a single fulcrum flange or with an L-shaped single support. This installation is more suitable for cables with a smaller outer diameter and lighter weight. When the outer diameter of the cable is large and the weight is large, that is, when the torque load of the reel is large, this installation form is thin and the stability is not enough. There are also double-support installation methods for stability. Because the mainspring spring used as the driving force of the existing elastic-driven cable reel is externally installed, it is installed on one end of the reel, and the collector is installed on the other end of the reel. Although the stability is enhanced, due to the large axial dimension, it needs to occupy a large installation space. In ...

Problems solved by technology

[0002] Most of the currently used elastic drive cable reels are installed with a single fulcrum flange or with an L-shaped single support. This installation is more suitable for cables with a smaller outer diameter and lighter weight. When the outer diameter of the cable is large and the weight is large, that is, when the torque load of the reel is large, this installation form is thin and the stability is not enough.

There are also double-support installation methods for stability. Because the mainspring spring used as the driving force of the existing elastic-driven cable reel is externally installed, it is installed on one end of the reel, and the collector is installed on the other end of the reel. Although the stability is enhanced, but due to the large axial dimension, it needs to occupy a large installation space

In addition, the reel of the elastic-driven cable reel generally adopts an integral welded structure, and its production cost is relatively high.
