Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 2-4, a snap-fit motor housing is shown. As shown in the figure, the motor casing includes a front casing 20 and a rear casing 10, the front casing 20 and the rear casing 10 form a containing cavity, and a motor assembly is arranged in the containing cavity, and the motor assembly is not shown in the figure. The front case 20 and the rear case 10 adopt a snap-in type mounting structure without additional auxiliary fixing means such as screws and the like. A plurality of protruding fasteners 11 are disposed on the rear case 10, and a plurality of insertion portions 21 corresponding to the fasteners 11 are disposed on the front case 20. The front case 20 includes a body 24 and side portions 22, and the insertion portion 21 is disposed between the body 24 and the side portions 22. The inserting portion 21 has an elastic limiting member 23 engaged with the body 24, and the locking member 11 is inserted between the elastic limiting member 23 and the side portion 22.

When the fastener 11 is pulled out, the elastic limiting piece 23 can abut against the side edge part 22; when the engaging element 11 is inserted, the elastic limiting element 23 is elastically retracted, so as to provide the possibility for inserting the engaging element 11. Preferably, the side portion 22 is provided with a step, and the fastener 11 is provided with a protrusion. When the latch 11 is inserted into the insertion part 21, the protrusion of the latch 11 can be engaged with the step of the side part 22. In the embodiment shown in fig. 4, the mating surfaces of the protrusion and the step may both be planar, making the snap fit tighter and easier to remove.

As shown in fig. 5, the elastic limiting member 23 may be in a zigzag shape as a whole, and the fixed end 231 is fixed to the body 24 of the front case 20. The other end of the elastic limiting member 23 is a free end, an elastic member 232 is disposed between the fixed end 231 and the free end, and the elastic member 232 may be in the form of a U-shaped elastic sheet. The free end of the resilient stop 23 is provided with a contact surface 234, preferably a vertical contact surface. The contact surface 234 is transitionally connected to the main portion of the elastic stopper 23 by the inclined surface 233. In alternative embodiments, as shown in fig. 6, the resilient member 232 may also be in the form of a spring or other resilient member that is retractable. When the elastic member 232 is a spring, the free end of the spring may also be provided with a vertical contact surface 234, the contact surface 234 being engaged with the inclined surface 233.

When the buckle is needed to be connected, the buckle piece is only needed to be aligned to the inserting part to be inserted, and the inclined part and the vertical contact surface are respectively arranged at the contact part of the elastic limiting part and the buckle piece, so that the insertion of the buckle piece can be completed only by overcoming the elasticity of the elastic limiting part. After the buckling piece is inserted into the inserting part, the protruding part on the buckling piece is clamped on the step of the side edge part and is pressed tightly by the elasticity provided by the elastic limiting part, so that the buckling piece is tightly and reliably connected with the inserting part. When the front shell and the rear shell need to be disassembled, the protruding part on the buckling piece can be separated from the step on the side edge part only by slightly pressing the part, which is clamped with the front shell, on the rear shell, and the part, which is contacted with the buckling piece, of the elastic limiting piece is a plane contact surface, so that the separation cannot be hindered, and the separation can be conveniently operated.

This application is through the setting of above-mentioned elasticity locating part for buckle spare male grafting portion width can be less than buckle spare's width, makes buckle spare fixed firm, is difficult for droing. In addition, the inclined surface and the plane contact surface are arranged, so that the insertion of the clamping piece is facilitated, resistance cannot be generated during the disassembly, the clamping piece cannot be blocked when being pulled out, and the installation and the disassembly are facilitated. The improvement of manufacturing and installation cost brought by adopting auxiliary fixing means such as screws in the prior art is avoided, and the installation is more firm and convenient, so that the device has beneficial technical effects.

The application still relates to a fan, and it includes as above the motor casing of buckle formula installation, be equipped with motor element in the motor casing, other parts such as stand, base all can adopt prior art, no longer describe repeatedly.

Although the embodiments disclosed in the present application are described above, the descriptions are only for the convenience of understanding the present application, and are not intended to limit the present application. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
