Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that the A-A in this utility model Fig. 1 is to schematic diagram.
In figure: 1-A-frame, 2-install sleeve, 3-the first support bar, 4-mounting post, 5-scale, 6-coat hook, 7-net, 8-swivel nut, 9-screw rod, 10-driven wheel of differential, 11-drive bevel gear, 12-rotating shaft, 13-mounting blocks, 14-crank, 15-the second support bar, 21-slippage slot, 22-gathering sill, 41-guide protrusions.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1-Fig. 2, in this utility model embodiment, a kind of arrangement for adjusting height for tennis net, including two installation sleeves 2 being set up in parallel, the bottom of described installation sleeve 2 is fixed with A-frame 1, is provided with slippage slot 21 in described installation sleeve 2, gathering sill 22 is offered on slippage slot 21 sidewall, being provided with mounting post 4 in described slippage slot 21, the sidewall of mounting post 4 is provided with guide protrusions 41, and described guide protrusions 41 is positioned at gathering sill 22；It is fixed with net 7 between two mounting posts 4, two mounting post 4 bottoms are fixedly connected with the first support bar 3, install for two and be fixedly connected with the second support bar 15 between sleeve 2, the downside in described first support bar 3 centre position is fixed with swivel nut 8, it is provided with screw rod 9 on the downside of described swivel nut 8, described screw rod 9 is connected by screw thread with swivel nut 8, driven wheel of differential 10 it is fixed with on screw rod 9, driven wheel of differential 10 side is engaged with drive bevel gear 11, and described drive bevel gear 11 is connected with crank 14 by rotating shaft 12.
Described mounting post 4 is provided with scale 5, for the extension elongation of accurate assurance mounting post 4.
The top of described mounting post 4 is provided with coat hook 6, is used for placing medicated clothing.
The lower end of described screw rod 9 is rotationally connected with the second support bar 15.
The upside of described second support bar 15 is provided with mounting blocks 13, and described rotating shaft 12 is arranged through mounting blocks 13, and mounting blocks 13 is used for supporting rotating shaft 12.
Operation principle of the present utility model is: when needs raise net 7, swing handle 14, handle 14 drives rotating shaft 12 to rotate, rotating shaft 12 drives drive bevel gear 11 to rotate, thus driving driven wheel of differential 10 to rotate, driven wheel of differential 10 drives screw rod 9 to rotate, thus swivel nut 8 rises, mounting post 4 is driven to rise, it is achieved thereby that the height adjustment of net 7；The reverse operating when needs reduce net 7.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
