Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1-7, the present embodiment provides a screw cover, which includes a cover body 1 and a connecting portion, the cover body 1 is provided with a hook portion 2, the connecting portion includes a clamping surface 3 and a mounting hole 4, the clamping surface 3 is located at two sides of the mounting hole 4, the hook portion 2 can smoothly pass through the mounting hole 4, the mounting hole 4 is communicated with a rotating groove 5, and the hook portion 2 passes through the rotating groove 5 and is clamped on the clamping surface 3. The connection portion in this embodiment is located on a control panel base of the electric appliance.

The mounting hole 4 of this screw lid makes hook portion 2 can pass smoothly, sets up rotation groove 5 and joint face 3 in the both sides of mounting hole 4, and hook portion 2 rotates the back and rotates 5 interior joint of inslot on joint face 3, can avoid hook portion 2 to produce the deformation, increase of service life, simultaneously, through rotating along the not equidirectional, can realize the installation and the dismantlement of screw lid, and is convenient laborsaving.

As shown in fig. 3 and 4, in the present embodiment, there are two hook portions 2, and rotational symmetry is formed by using the center of the cover 1 as the center of symmetry, so that the force is balanced during connection, the installation is stable, and the number of the installation holes 4 on the connection portion is the same as the number of the hook portions 2. According to the space size and the structural layout of the screw cover, a plurality of bent hook parts 2 can be selected, and the bent hook parts 2 form rotational symmetry by taking the center of the cover body 1 as a symmetry center.

The screw cover further comprises a connecting rib 6, and the bent hook part 2 is fixed on the cover body 1 through the connecting rib 6. The cover body 1 is of a plane structure, the connecting ribs 6 are vertically connected with the cover body 1, and the bent hook parts 2 are parallel to the cover body 1 and point to the direction far away from the center of the cover body 1. A positioning column 7 is arranged on the hook part 2, the positioning column 7 points to the cover body 1, a positioning hole 8 is arranged on the clamping surface 3, and the positioning column 7 extends into the positioning hole 8 to realize matching. The cooperation of reference column 7 and locating hole 8 can avoid leading to the screw lid to rotate owing to external factors such as vibration and deviate from connecting portion.

Be provided with elastic component 9 between lid 1 and the connecting portion, elastic component 9 selects as the shell fragment in this embodiment, and the shell fragment is fixed on lid 1, and when the screw lid was connected with connecting portion, elastic component 9 was in compression state, can make lid 1 receive the power of keeping away from connecting portion towards for reference column 7 more closely cooperates with locating hole 8, prevents that reference column 7 from deviating from locating hole 8. The elastic element 9 can also be fixed to the connection part in other ways, depending on the case.

In the embodiment, the number of the elastic sheets is two, the two elastic sheets are arranged at intervals with the hook part 2, and the elastic force borne by the cover body 1 after the screw cover is connected is balanced.

As shown in fig. 5 and 6, the connecting portion is provided with an elastic member support platform 10 for supporting the elastic member 9, the elastic member support platform 10 is arc-shaped, the clamping surface 3 is located on a surface of the elastic member support platform 10 away from the elastic member 9, and a surface of the elastic member support platform 10 opposite to the screw cover is used for supporting the elastic member 9.

The center of the connecting part is provided with a groove 11, and the bottom of the groove 11 is provided with a threaded hole 12 for a screw 13 to pass through. The bottom of the recess 11 is lower than the surface of the elastic member support table 10 supporting the elastic member 9, the elastic member support table 10 is located around the recess 11, and the rotation groove 5 is opened on the side wall of the recess 11.

When the screw cover is mounted and dismounted, the specific process is as follows:

after the screw 13 is installed in the threaded hole 12 on the groove 11, the screw cover is pushed in the direction of the connecting portion by corresponding the position of the hook portion 2 on the screw cover to the installation hole 4 on the connecting portion, then after the elastic sheet contacts the elastic member support table 10, the cover body 1 is continuously pressed with force, and the elastic sheet on the cover body 1 is compressed and rotates towards the direction of the rotating groove 5, at this time, the positioning column 7 contacts with the clamping surface 3 and generates dynamic friction force, so that the hook portion 2 passes through the rotating groove 5 to rotate until the positioning column 7 extends into the positioning hole 8, and stops pressing the cover body 1, and the installation is finished, as shown in fig. 7, the structure schematic diagram after the screw cover and the connecting portion are assembled is shown.

When the screw cover needs to be disassembled, the cover body 1 is pressed down firstly, so that the positioning column 7 is separated from the positioning hole 8, then the cover body 1 is rotated, the bent hook part 2 is rotated to the mounting hole 4, the force applied to the cover body 1 is stopped, and the screw cover can be separated from the connecting part.

The embodiment also protects a washing machine, which adopts the screw cover. In particular, the screw cover is applied to the pulsator washing machine.
