Preferably, the jack in the center of the reel and the insertion section of the transmission rod are rectangular.
Preferably, the support is U-shaped, and open slots are arranged on two side edges.
Preferably, two check rings are arranged on the reel, a winding area is arranged in the space between the two check rings, and the outer side surfaces of the two check rings are attached to the inner side surface of the support.
Preferably, the guide assembly comprises a first guide wheel and a second guide wheel, and the steel wire is connected with the hand crank through the first guide wheel after being turned by the second guide wheel.
Preferably, the two ends of the reel are provided with bearing brackets, and the bearing brackets are fixed on the outer side surface of the support through screws.
Preferably, the upper end and the lower end of the bearing bracket are both provided with openings, and the length of each opening is smaller than the diameter of the bearing.
The conversion mechanism has the beneficial effects that the conversion mechanism is applied to a manual mechanism of a translation roller shutter, the main function is that rod type transmission is converted into steel wire transmission, the steel wire is flexible, the problem of the installation position of a hand crank facing various terrains in the actual use process can be solved through the reversing wheel, and the mechanism can be used for forward transmission and reverse transmission.
Drawings
The utility model will be described in further detail with reference to the drawings and the detailed description.
FIG. 1 is a schematic diagram of the overall structure of the present utility model.
Fig. 2 is a schematic diagram of an explosion in practice of the present utility model.
In the figure, 1 is a hand crank; 2 is a guide wheel I; 3 is a steel wire; 4 is a transmission rod; 5 is a support; 6 is a guide wheel II; 7 is a bearing; 8 is a bearing bracket; 9 is a screw; 10 is a reel.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 and 2, a conversion mechanism comprises a transmission rod 4 and a hand crank 1, wherein the transmission rod 4 is used for one of winding and unwinding, the hand crank 1 is opposite to the transmission rod 4, the hand crank 1 is wound if the transmission rod 4 is unwound, the transmission rod 4 is inserted into a reel 10 erected in a support 5, a steel wire 3 is wound on the reel 10, the steel wire 3 is connected with the hand crank 1 through a guide assembly, and the reel 10 can only be driven by one of the transmission rod 4 or the hand crank 1 in one time.
The jack in the center of the reel 10 and the insertion section of the transmission rod 4 are rectangular, so that the reel 10 cannot be driven to rotate when the transmission rod 4 rotates after being inserted.
The support 5 is U-shaped, and is provided with open slots on two side edges, and the open slots are convenient for placing the reel 10, and are convenient for disassembly in the later stage.
The reel 10 is provided with two check rings, a winding area is arranged in the interval between the two check rings, the outer side surfaces of the two check rings are attached to the inner side surface of the support 5, and the check rings can prevent the displacement of the steel wire 3 when the steel wire is wound, so that the steel wire is always kept in the winding area.
The guide assembly comprises a first guide wheel 2 and a second guide wheel 6, the steel wire 3 is connected with the hand crank 1 through the first guide wheel 2 after being turned by the second guide wheel 6, the guide wheels are not limited to two groups, multiple turning can be carried out through a plurality of guide wheels, and the number of the guide wheels can be increased or decreased according to an actual installation scene.
The two ends of the reel 10 are respectively provided with a bearing bracket 8, the bearing brackets 8 are fixed on the outer side surface of the support 5 through screws 9, and the displacement of the reel 10 is prevented through the bearing brackets 8.
The upper and lower ends of the bearing bracket 8 are provided with openings, the length of each opening is smaller than the diameter of the bearing 7, the running condition can be well checked by arranging the openings, and the bearing bracket can be observed without disassembling the bearing bracket during maintenance.
