Detailed Description

In order to better understand the purpose, structure and function of the present invention, a clamshell housing and a household appliance of the present invention are further described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the clamshell casing of the present invention includes a base 1 and a cover 2, wherein the cover 2 is linked to the base 1, so that the cover 2 covers the base 1 to close a cavity on the base 1.

As shown in fig. 2 and 3, in order to realize the detachment of the cover 2 and the base 1, a hinge block 3 is detachably mounted on the base 1, the hinge block 3 is provided with the cover 2 capable of rotating relatively, and the cover 2 rotates and covers the base 1, so that the cover 2 and the base 1 are detached by detaching the hinge block 3.

The base 1 is provided with a driven clamping part, correspondingly, the hinge block 3 is provided with a driving clamping part, and the driving clamping part and the driven clamping part are rotationally clamped and fixed, so that the base 1 and the hinge block 3 can be detachably fixed.

As shown in fig. 4 to 7, the active engaging portion includes a positioning shaft 31 disposed on the hinge block 3, a sliding groove 32 is formed on a side surface of the positioning shaft 31, the sliding groove 32 extends from one end of the positioning shaft 31 to the other end, and a locking groove 33 extending along the circumferential direction is formed at the end of the sliding groove 32. The driven clamping part comprises a positioning hole 11 arranged on the base 1, and a clamping block 12 is arranged on the inner wall of the positioning hole 11; the positioning shaft 31 is inserted into the positioning hole 11, so that the latch 12 slides along the slide groove 32 and is clamped into the latch groove 33.

Specifically, the movement of the latch 12 includes two portions, i.e., sliding along the slide groove 32 and rotating into the latch groove 33. The first of these, the positioning shaft 31, is inserted in a manner dependent on the angle of the slide groove 32 with respect to the positioning shaft 31. Generally, the slide groove 32 is spirally provided on the side of the positioning shaft 31, so that the positioning shaft 31 needs to be rotatably inserted into the positioning hole 11. When the fixture block 12 moves to the end of the sliding groove 32, the positioning shaft 31 is rotated in parallel, so that the fixture block 12 rotates to enter the clamping groove 33, and clamping fixation is achieved. Of course, besides the spiral arrangement of the sliding slot 32, the sliding slot 32 can also extend along the positioning shaft 31 in the axial direction, and at this time, the positioning shaft 31 can be directly inserted after aligning the fixture block 12 and the sliding slot 32. However, it is preferable to use the sliding groove 32 with a spiral arrangement, only the positioning shaft 31 needs to be rotated, the step of aligning the latch 12 and the sliding groove 32 can be omitted, and the engaging groove 33 extends from the end of the sliding groove 32 to the side far away from the sliding groove 32, so as to ensure the consistent rotation direction of the positioning shaft 31, and facilitate the user to detach the positioning shaft.

Also, in order to facilitate the insertion of the latch 12 into the slide groove 32, a guide angle 321 is formed at one side of an entrance of the slide groove 32 to increase a caliber at the entrance of the slide groove 32, so that the latch 12 can be easily inserted into the slide groove 32. The end of the latch 12 is formed with a guiding inclined plane 121, and the guiding inclined plane 121 reduces the width of the end of the latch 12 inserted into the slot 33, so that the latch 12 is inserted into the slot 33.

The side wall of the clamping groove 33 is provided with a convex point 34, and the clamping block 12 is provided with a notch 122 for clamping the convex point 34, so that the notch 122 and the convex point 34 are clamped, the resistance of the clamping block 12 moving out of the clamping groove 33 is increased, and the hinge block 3 and the base 1 are connected and fastened.

Generally, at least two sets of sliding grooves 32 and locking grooves 33 are arranged on the positioning shaft 31, and are uniformly and symmetrically arranged, and the locking blocks 12 on the corresponding positioning holes 11 are also arranged corresponding to the sliding grooves 32, so as to ensure that the number, the shape and the relative position are consistent. However, in consideration of the limited space on the positioning shaft 31, two positioning shafts may be provided as shown in fig. 5.

Besides the active engaging portion includes the positioning shaft 31 disposed on the hinge block 3 and the driven engaging portion includes the positioning hole 11 disposed on the base 1, the active engaging portion may also include the positioning hole 11 disposed on the base 1 and the driven engaging portion includes the positioning shaft 31 disposed on the hinge block 3. Namely, the specific structures of the base 1 and the hinge block 3 are interchanged, and the rotary clamping can be realized.

Further, when the positioning shaft 31 is screwed into the positioning hole 11, the hinge block 3 abuts on the base 1.

The connection structure of the cover body 2 and the hinge block 3 is as follows: the cover body 2 is provided with a rotating shaft 4, the hinge block 3 is provided with a through hole 35 for the rotating shaft 4 to penetrate through, and therefore the cover body 2 and the hinge block 3 are connected in a rotating mode. Moreover, the hinge block 3 is formed with a mounting groove 36, a portion of the rotating shaft 4 in the mounting groove 36 is sleeved with a hinge spring, both ends of the hinge spring are respectively formed with a first torque arm and a second torque arm, the first torque arm is fixed with the hinge block 3, and the second torque arm is fixed with the cover body 2, so that the cover body 2 has an automatic cover opening function. The side wall of the mounting groove 36 is provided with an avoiding hole 37 for the hinge spring to deform and extend so as to prevent the hinge spring from interfering with the hinge block 3.

The utility model also discloses a household appliance which comprises the flip shell. Specifically, the household appliance can be a shell in which a cover body 2 and a base 1 are hinged, such as an electric cooker, a micro-pressure cooker, an electric kettle, an electric soup cooker and the like.
