The utility model discloses a household appliance, like fan, humidifier etc. have the electrical apparatus casing that needs two halves shell amalgamation to form. In order to fix the two housings of the electrical appliance to each other, a connecting structure for connecting the two half-shells is required.

Taking the fan as an example, the cooling machine comprises a machine head, an electric appliance shell and a base, and the fan in the machine head is used for blowing air to realize cooling. As shown in fig. 1, the appliance casing, as mentioned above, comprises two half-shells, a first half-shell 1 and a second half-shell 2, which are assembled with each other; the two half shells may be a front shell and a rear shell, a left shell and a right shell, even a top shell and a bottom shell, and so on. The general splicing fixing mode is a seam allowance and a buckle, and the two half shells are pre-fixed through the seam allowance and the buckle.

Referring to fig. 2 and 3, in order to solve the problem of uneven gap between the two half-shells, the housing of the electrical appliance is further provided with a connecting member 3 for connecting the two half-shells. The first half shell 1 is provided with a first driven part 11, and the second half shell 2 is provided with a second driven part 21; the connecting piece 3 is provided with a first clamping rib 31 corresponding to the first driven part 11 and a second clamping rib 32 corresponding to the second driven part 21, namely, two clamping ribs are respectively arranged corresponding to the driven parts on the two half shells. As the connecting piece 3 is inserted towards the splicing position of the two half shells, the two clamping ribs press the first driven part 11 and the second driven part 21, so that the two half shells are folded.

Generally, in order to ensure the stress balance of the two half shells, the connecting pieces 3 need to be symmetrically arranged at two sides of the electric appliance shell, and the two half shells are symmetrically forced to be closed, so that the gap between the two half shells is controlled.

As shown in fig. 3 and 6, the first beads 31 and the second beads 32 form a throat 4 between the first driven portion 11 and the second driven portion 21; as the connecting member 3 is inserted, the throat 4 gradually compresses the first driven portion 11 and the second driven portion 21. Wherein, the necking 4 is arranged opposite to the driven part. Thus, the first clamping bead 31 is provided with a first driving surface 311, the second clamping bead 32 is provided with a second driving surface 321, the first driving surface 311 and the second driving surface 321 are arranged adjacently, and the throat 4 is located between the two driving surfaces; the first driven part 11 is provided with a first driven surface 121 which is abutted with the first driving surface 311, and the first driving surface 311 and the first driven surface 121 are arranged at an included angle; the second driven part 21 is provided with a second driven surface 221 abutting against the second driving surface 321, and the second driving surface 321 and the second driven surface 221 are arranged at an included angle.

If the vertical surface is taken as a reference, three setting modes can be adopted: the driving surface is a bevel, and the driven surface is a plane; the driving surface is a plane, and the driven surface is an inclined surface; the driving surface and the driven surface are inclined surfaces, but an included angle exists. In any case, as the connector 3 is inserted, the half shells are closed because the space between the first clamping rib 31 and the second clamping rib 32 is reduced with respect to the driven portions of the half shells.

As shown in fig. 3 to 5, in order to provide the driven surface in the driven portion, the first driven portion 11 is provided with a first clamping hole 12 into which the first clamping rib 31 is inserted, and the first driven surface 121 is a side wall of the first clamping hole 12 abutting against the first driving surface 311; the second driven portion 21 has a second clamping hole 22 into which the second clamping rib 32 is inserted, and the second driven surface 221 is a side wall of the second clamping hole 22 abutting against the second driving surface 321. And due to the insertion of the clamping ribs and the clamping holes, the pre-fixing of the connecting piece 3 is also completed. And in order to insert the clamping ribs into the clamping holes, guide oblique angles are formed at the tail ends of the two clamping ribs.

For preliminary fixing of the connecting element 3, the first half-shell 1 is formed with a first half-slot 13 and the second half-shell 2 is formed with a second half-slot 23; the first half groove 13 and the second half groove 23 are spliced into a socket along with the folding of the two half shells; the socket exposes the two driven parts and allows the connecting piece 3 to be inserted.

A flange 33 is formed on the side surface of the connecting piece 3, and the flange 33 is abutted against the edge of the socket; and a clamping block 34 is formed on one side of the flanging 33, and the edge of the insertion opening is clamped between the clamping block 34 and the flanging 33.

In addition, the connecting piece 3 is provided with a fixing piece which fixedly connects the connecting piece 3 and the two half shells. Generally, the connection is a screw 5, so a bolt connection is adopted.

For example, tapping screws are used to penetrate the connector 3 and the driven portions of the two half shells one by one and fix them. However, a direct self-tapping screw is not preferred, and the connecting piece 3 and the two connecting parts need to be overlapped and nested to ensure that the two half shells are connected and fastened.

Specifically, the first driven portion 11 forms a pocket 14, and one end of the second driven portion 21 is inserted into the pocket 14 to overlap the first driven portion 11 and the second driven portion 21.

The first driven part 11 is provided with a positioning hole 111, the connecting element 3 forms a positioning table 35, and the positioning table 35 is embedded into the positioning hole 111 for limiting. Furthermore, to ensure uniform force, the positioning hole 111 is generally located between the first clamping rib 31 and the second clamping rib 32, i.e. located in the throat 4. In this case, the screw 5 penetrates the positioning table 35 and is screwed to the second driven portion 21, which provides a better connection effect.

In order to ensure the appearance, the connecting piece 3 is used for arranging a countersunk hole 37 of the connecting piece 3, the countersunk hole 37 is provided with a rubber plug 6, and the rubber plug 6 covers the screw 5 to ensure that the surface of the connecting surface is flat.

In conclusion, preassembly is completed through the buckle to prevent separation; the positioning table 35, the positioning hole 111, and the screw hole of the second driven portion 21, which are overlapped with each other, are connected by the screw 5, thereby completing the fixing. Besides, the clamping and bolt connection modes can be adopted simultaneously, only the clamping or bolt connection mode can be adopted, and other fixing modes such as pin connection and the like can also be adopted.

Referring to fig. 6 and 7, the first clamping rib 31 and the second clamping rib 32 are disposed on the back of the connecting member 3, and the front of the connecting member 3 forms a handle slot 36, so that the connecting member 3 is used as a handle, which is more beautiful and saves cost.

The second half shell 2 is formed with butt muscle 24, the top surface butt of butt muscle 24 and handle to guarantee that the handle atress is stable. In order to ensure the hand feeling of the handle groove 36, the fixing member is disposed on the lower side of the bottom wall of the handle groove 36 to reduce the contact between the hand and the fixing member.

In conclusion, the two clamping ribs extrude the two driven parts to enable the two half shells to be pressed inwards, and horizontal radial directions are restrained. While the screws 5 fix the two half-shells and the connector 3 once, constraining the horizontal axial direction. When the lifting handle is used, the top of the handle buckling groove 36 is stressed, the abutting rib 24 abuts against the top surface of the handle buckling groove 36, the vertical direction is restrained, and the gravity of the whole machine in the vertical direction can be borne. Therefore, the three directions are all restricted, and the method is feasible and reliable. Wherein, owing to the extrusion effect of the clamping rib, the gap between the two half shells can be well controlled, and the appearance is ensured.
