Detailed Description
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that the conventional terms should be interpreted as having a meaning that is consistent with their meaning in the relevant art and this disclosure. The present disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments.
The following is a further description of the technical solutions of the present invention, but the present invention is not limited to these examples.
Example one
Fig. 1 shows a chain block of an electric zipper of this embodiment, which includes a housing 1, and a driving sprocket 2, a driven sprocket 3, and a driving motor 4 disposed in the housing 1. The housing 1 is of a split structure and is provided with a chain inlet 11 and a chain outlet 12, and the chain 5 enters the housing 1 from the chain inlet 11 and winds around the driven sprocket 3 and the driving sprocket 4 and then leaves the housing 1 through the chain outlet 12. The split-type housing 1 refers to any housing structure that can be opened in the prior art, for example, a structure including a housing and a housing cover, the housing cover can be snapped on the housing, or the housing cover can be fixedly connected to the housing by a fixing member such as a screw. The driving sprocket 2 and the driven sprocket 3 are rotatably fixed in the housing 1 by a rotating shaft, and the driving sprocket 2 is provided with a driving motor interface, such as a gear box or a key-fitting structure, for driving connection with a driving motor 4. A driving motor mounting opening is arranged at the position of the driving motor interface of the driving chain wheel 2 on the housing 1. Driven sprocket 3 locates one side of drive sprocket 2 and chain 5 is the S type around establishing on drive sprocket 2 and driven sprocket 3, through driven sprocket 3 in order to guarantee the abundant laminating of chain 5 and drive sprocket 2. The housing 1 is also provided with a handrail 13 on one side for an operator to manually pull and secure the entire tool. Preferably, the driven sprocket 3 of the present embodiment is also provided with a driving motor interface for driving and connecting a driving motor, and the housing 1 is provided with a driving motor mounting opening corresponding to the driving motor interface position of the driven sprocket. The driving sprocket 2 and the driven sprocket 3 in this embodiment are symmetrically disposed in the housing 1, and "symmetrical" herein means that the structures of the driving sprocket 2 and the driven sprocket 3 as a whole before and after being rotated 180 degrees are kept identical. When using this chain block jack-up weight and highly great, can pass through the driving motor interface access driving motor in driving sprocket department, adopt electric mode drive driving sprocket to rotate, it is nimble convenient, need not additionally to change the design of chain block:
firstly, the housing 1 is opened, the chain 5 of the chain block is wound into the driven sprocket 3 and the driving sprocket 2 in sequence and penetrates out of the housing through the chain outlet 12, and then the housing is closed. Naturally, the chain is wound tightly on the two chain wheels. The handrail 13 on the housing 1 is manually pulled downwards, and after the driving motor 4 is inserted into a driving motor interface of the driving chain wheel, the chain can be tensioned by starting the driving motor in the tensioning direction. In this embodiment, the driving motor 4 is a speed-adjustable motor, and a fast zipper or a stable zipper can be realized as required. The driving motor is detached from the driving chain wheel, after the housing 1 is rotated anticlockwise by one hundred eighty degrees, the driving motor is inserted into a driving motor interface of another chain wheel (namely, a driven chain wheel), the reverse zipper can be realized, and the chain is not required to be wound again.
Although embodiments of the present invention have been described, various changes or modifications may be made by one of ordinary skill in the art within the scope of the appended claims.
