In fig. 1-5, 1, the cap is screwed; 2. a support; 3. a spring; 4. a screw; 5. limiting teeth; 6. a second tooth; 7. a handle placement hole; 8. a first tooth; 9. a threaded bore post; 10. screwing the cover body; 11. and (4) a hole.
Detailed Description
Fig. 1 is a schematic sectional view showing a screw cap in a knob device for placing an operating handle according to the present invention, fig. 2 is a schematic perspective view showing the screw cap, fig. 3 is a schematic sectional view showing a support, fig. 4 is a schematic perspective view showing the support, and fig. 5 is a schematic perspective view showing an assembly of the screw cap and the support. As can be seen from the structural combination shown in fig. 1-5, the knob device for placing the operating handle comprises a screw cap 1 and a support 2 which are matched with each other, the screw cap 1 comprises a screw cap body 10 with a U-shaped cross section and a threaded hole column 9 which is positioned in the middle of the screw cap body 10 and is perpendicular to the plane of the screw cap body 10, the threaded hole column 9 is positioned at the same side of the opening direction of the screw cap body 10, a handle placing hole 7 is arranged at the side of the screw cap body 10 opposite to the threaded hole column 9, and a first tooth 8 is arranged at the bottom of the screw cap body 10; be equipped with on the support 2 with first tooth 2 matched with second tooth 6, still be equipped with the rotatory spacing tooth 5 of restriction spiral cover 1 on the support 2, follow the length direction of support 2, and the middle part that is located support 2 is equipped with the hole 11 of installation screw hole post 9, spiral cover 1 and support 2 pass through the cooperation installation in screw hole post 9 and hole 11 and be in the same place.
The shape of the handle placing hole 7 is consistent according to the shape of a handle to be installed; the screw cap 1 and the support 2 are both made of nylon materials through injection molding.
A use method of a knob device for placing an operating handle comprises the following steps:
1) inserting a threaded hole column 9 on the screw cap 1 into a hole 11 on the support 2, and matching a first tooth 8 of the screw cap 1 with a second tooth 6 on the support 2;
2) the spring 3 is arranged in a hole 11 on the support 2 and sleeved on a threaded hole column 9 on the screw cap 1;
3) installing the screw 4 in the threaded hole on the threaded hole column 9 and pressing the spring 3;
4) all the parts can be assembled together by rotating the screw 4.
The screw 4 is provided with a flat pad which plays a role in limiting.
The working principle of the invention is as follows: spiral cover 1 all has matched with tooth characteristic with support 2, through the meshing of first tooth 8 and second tooth 6, the first tooth 8 of rotatory spiral cover 1, spring 3 outwards withstands spiral cover 1, until first tooth 8 and second tooth 6 re-mesh, spring 3 returns the normal position, can easily rotate spiral cover 1, arranges the operating handle that the handle placed in the hole 7 and can follow spiral cover 1 rotatoryly. Because operating handle when not using, generally the level is placed, only needs to rotate 90 degrees during the use, becomes vertical position, conveniently takes out the use, after finishing using, inserts in handle and places in the hole 7 and then contrarotate 90 degrees and still keep the level to place can. Therefore, according to the operating mode, design three first tooth 8 on spiral cover 1, separate 90 degrees distribution, design three second tooth 6 and a spacing tooth 5 on support 2 and separate 90 degrees distribution respectively, wherein spacing tooth 5 plays the effect that restriction spiral cover 1 was rotatory at will, makes spiral cover 1 only can rotate 90 degrees, only level and two perpendicular stations, but two positions forward reverse rotation switch at will.
The knob device for placing the operating handle with the structure and the use method thereof can facilitate the placement of the operating handle by matching the screw cap with the support and placing the handle in the handle placing hole; and the handle placing hole can be freely changed in shape according to the shape of the handle, the universality is strong, and the placing requirements of handles in various shapes can be met.
