For example, as shown in Figure 1-Figure 3, screw threads for fastening body 11 can be located at screw thread with generally cylindrical structure, embedded division 12
The lower end of fastening body 11, the bottom of screw threads for fastening body 11 is provided with platform part 13, and the upper surface of platform part 13 is burnishing surface, when
When the upper end of threaded fastener 1 and other structures such as compressor etc. are connected, can be provided for other structures such as compressor etc.
One smooth plane, and platform part 13 is metalwork, can play a part of to protect chassis.The cross section of platform part 13 is substantially
Can be the shapes such as polygon, ellipse, Long Circle or circle, embedded division 12 is located at the lower section of platform part 13, and embedded division 12
Adding for threaded fastener 1 can be reduced by stamping mold punch forming, so as to improve the processing efficiency of threaded fastener 1
Work cost.And in chassis assembly, threaded fastener 1 and chassis can improve chassis assembly with integrated injection molding, thus
Shaping efficiency, reduce the shaping cost of chassis assembly.
Specifically, in the process of threaded fastener 1, when screw threads for fastening body 11 and platform part 13 are machined
Afterwards, the punch forming in stamping mold of embedded division 12, such that it is able to realize being rapidly completed the processing of embedded division 12.To complete to process
Threaded fastener 1 be arranged on chassis injection mold on, make the lower section of the platform part 13 of threaded fastener 1 structure (including
Embedded division 12) it is put into the molding space of injection mold, then to the plastics of molding space injection melting, plastics cooling and solidifying
After can form chassis, so as to complete the shaping of chassis assembly.Thus, can be with punching press by the setting on threaded fastener 1
The embedded division 12 of shaping, so as to improve the processing efficiency of threaded fastener 1, reduces the processing cost of threaded fastener 1,
When chassis assembly is molded, embedded division 12 is embedded in chassis to realize the injection moulding of chassis assembly, so as to improve chassis group
The shaping efficiency of part, reduces the shaping cost of chassis assembly.
The chassis assembly for household electrical appliance according to embodiments of the present invention, can be with by setting on threaded fastener 1
Stamping forming embedded division 12, improves the processing efficiency of threaded fastener 1.And, in chassis assembly injection moulding, will be embedding
Enter in the insertion chassis of portion 12, so as to improve the shaping efficiency of chassis assembly, reduce the shaping cost of chassis assembly.
In one particular embodiment of the present invention, embedded division 12 can be one time punching molded by stamping mold, Er Qiechong
Compression mould disposably can also carry out punching press to multiple threaded fasteners 1, so that stamping mold can disposably stamp out multiple
Embedded division 12, hereby it is achieved that the production in enormous quantities of threaded fastener 1, further increases the processing effect of threaded fastener 1
Rate, reduce further the processing cost of threaded fastener 1.
In one embodiment of the invention, as shown in Figure 1-Figure 3, at least part of cross section of embedded division 12 is not rounded
Face, and embedded division 12 is embedded in chassis, so that the cross section of embedded division 12 is non-disc can at least partly prevent embedded division
12 there is the axial rotation around embedded division 12 relative to chassis, it is ensured that be fixedly connected between threaded fastener 1 and chassis
Reliability.
In an alternate embodiment of the present invention where, embedded division 12 includes that one end is connected and the other end is circumferentially spaced
The many sub- embedded divisions 121 opened.For example, four sub- embedded divisions 121 are shown in the example of Fig. 1-Fig. 3, four sub- embedded divisions
121 upper end is connected, and four lower end edge embedded divisions 12 of sub- embedded division 121 are circumferentially spaced one from the other so that embedded division 12
The cross section of bottom is non-disc.Thus, many sub- embedded divisions 121 are set to by by embedded division 12, embedded division can be caused
12 at least part of cross section is non-disc, so as to ensure that the reliability being fixedly connected between threaded fastener 1 and chassis.
In further embodiment of the present invention, embedded division 12 generally away from screw threads for fastening body 11 one end have pass through
Wear the truncated cone-shaped structure of the end face of embedded division 12 and at least one groove 12a of outer peripheral face.For example, as shown in Figure 1-Figure 3, it is embedded
Portion 12 substantially can be truncated cone-shaped structure, and truncated cone-shaped structure the less one end of cross sectional dimensions and the phase of screw threads for fastening body 11
Even, groove 12a can be formed by the part of the lower surface of embedded division 12 is upwardly recessed, and groove 12a is along the radial direction of embedded division 12
The outer peripheral face of embedded division 12 is run through.Thus, groove 12a is set to form embedded division 12 by truncated cone-shaped structure, also may be used
It is fixed between threaded fastener 1 and chassis so as to ensure that to cause that at least part of cross section of embedded division 12 is non-disc
The reliability of connection.And, embedded division 12 in chassis from up to down with depth increase, its cross sectional dimensions increase,
Can prevent embedded division 12 from occurring along the movement of the axial direction of embedded division 12, so as to further ensure threaded fastener relative to chassis
The reliability being fixedly connected between 1 and chassis.
As shown in Figure 1-Figure 3, groove 12a is two, two groove 12a crisscrosses, and two groove 12a are
V-shaped groove.Thus, on the premise of ensureing that groove 12a can cause at least part of cross section of embedded division 12 to be non-disc, subtract
The manufacturing procedure of few groove 12a, improves the processing efficiency of groove 12a, and, two groove 12a crisscrosses so that
The intensity equalization of each several part of embedded division 12, it is ensured that embedded division 12 it is attractive in appearance.Additionally, groove 12a is set into V-shaped groove so that
The simple structure of groove 12a, it is easy to process, while facilitating the processing of stamping mold.
Certainly, the number and concrete shape of groove 12a can be set according to actual requirement, for example, groove 12a can be set
It it is one, three or more than three, groove 12a can be deep-slotted chip breaker, rectangular channel etc., so as to preferably meet practical application.
As shown in Figure 1-Figure 3, platform part 13 and embedded division 12 are preferably by between setting, and platform part 13 and embedded division 12
Part cross sectional dimensions of the cross sectional dimensions less than the lower end of embedded division 12, thus, threaded fastener 1 and chassis integrated injection molding
During shaping, more plastics can be filled between platform part 12 and embedded division 12, can further prevent embedded division 12 relative to
Chassis occurs along the movement of the axial direction of embedded division 12, it is ensured that the reliability being fixedly connected between threaded fastener 1 and chassis.
