With reference to figure 1 and Fig. 2 the refrigerator according to the embodiment of the invention is described below.
Refrigerator according to the embodiment of the invention comprises: casing 1, door body 2, hinge shaft sleeve 3 and hinge seat 4.
Particularly, door body 2 is provided with installing hole 21, can be provided with the locating slot (not shown) on the sidewall of installing hole 21.Hinge shaft sleeve 3 is installed in the installing hole 21, and hinge shaft sleeve 3 comprises location rib 31 and cylindrical shell 32.Hinge seat 4 is fixed on the casing 1 and hinge seat 4 is provided with hinge axis 41, and hinge axis 41 is engaged in the cylindrical shell 32 pivotly.Thus, door body 2 is installed on the casing 1.
Following with reference to the hinge shaft sleeve 3 of figure 3-5 specific descriptions according to the embodiment of the invention.As stated, hinge shaft sleeve 3 comprises location rib 31 and cylindrical shell 32, and cylindrical shell 32 has the circular mating holes 35 that cooperates with hinge axis 41.Location rib 31 is located on the outer wall of cylindrical shell 32 and along axial (being above-below direction among Fig. 4) extension of cylindrical shell 32; So that be formed on a body 2 on installing hole 21 sidewalls on locating slot match; From playing the positioning action to hinge shaft sleeve 3, promptly hinge shaft sleeve 3 can not rotate with respect to installing hole 21.
Thus; Hinge shaft sleeve 3 according to the embodiment of the invention; Through cooperating of location rib 31 and locating slot; Can make hinge shaft sleeve 3 not relatively installing hole 21 rotate; Therefore need not and to foam with door body 2 again in the ABC of body 2 of hinge shaft sleeve 3 prepackages; Avoid in foaming process, causing hinge shaft sleeve 3 deflection to take place or leak to foam like this, and then caused problems such as hinge shaft sleeve 3 and hinge axis 41 interfere, improved product percent of pass and product quality.In addition, hinge shaft sleeve 3 according to the present invention can have been simplified manufacturing process, improved manufacturing efficient and self structure simple, be convenient to processing and manufacturing.
Preferably, location rib 31 is two, two location ribs 31 radially being oppositely arranged along cylindrical shell 32.Through cooperating of these two location ribs 32 and two locating slots corresponding, guarantee that further hinge shaft sleeve 3 can not rotate with respect to installing hole 21 with it.
As shown in Figure 3, according to an example of the present invention, the profile of the cross section of cylindrical shell 32 can be circle.
According to another example of the present invention, the profile of the cross section of cylindrical shell 32 also is square, and accordingly, installing hole 21 also is adaptive with it square opening.Setting can guarantee further that hinge shaft sleeve 3 can not rotate with respect to installing hole 21 like this.
According to one embodiment of present invention, cylindrical shell 32 is provided with crossed beam trunking 34, and crossed beam trunking 34 is along the perisporium that radially runs through cylindrical shell 32 of cylindrical shell 32 and extending axially on the whole length of cylindrical shell 32 along cylindrical shell 32.
Thus; The hinge shaft sleeve 3 of the embodiment of the invention; The line opening of crossing through crossed beam trunking 34 and hinge axis 41 makes wire harness 5 walk in hinge shaft sleeve 3 and hinge axis 41 inside and passes a body 1 from hinge axis 41 ends; The end that not be used in a body 2 on the one hand is set like this for wire harness 5 outlet is set separately, therefore simplified manufacturing process; On the other hand, wire harness 5 can not caused wire harness 5 impaired by hinge shaft sleeve 3 compressings.
As shown in Figure 3, preferably, the two sides of crossed beam trunking 34 are arcwall face, in case principal vertical line bundle 5 is scratched by the side of crossed beam trunking 34 when crossed beam trunking 34 gets into hinge shaft sleeve 3 inside.
Like Fig. 4 and shown in Figure 5, an end of cylindrical shell 32 is provided with flange 33, and installing hole 21 is provided with expansion section 212 (as shown in Figure 2, flange 33 is positioned at the upper end of cylindrical shell 32, and expansion section 212 is positioned at the upper end of installing hole) accordingly.Hinge shaft sleeve 3 is being installed in the process in the installing hole 21, and cooperating of the expansion section 212 through flange 33 and installing hole 21 is convenient to install hinge shaft sleeve 3.
The refrigerator of the embodiment of the invention; Through cooperating of location rib 31 and locating slot; Can make hinge shaft sleeve 3 not relatively installing hole 21 rotate; Therefore need not in the ABC of body 2 of hinge shaft sleeve 3 prepackages; Again with 2 foaming of door body; Avoid in foaming process, causing hinge shaft sleeve 3 deflection to take place or leak to foam like this, and then caused problems such as hinge shaft sleeve 3 and hinge axis 41 interfere, improved product percent of pass and product quality.In addition, refrigerator according to the present invention has been simplified manufacturing process, has improved manufacturing efficient and has reduced manufacturing cost.
As shown in Figure 2; According to one embodiment of present invention; One end of hinge shaft sleeve 3 is provided with flange 33; Installing hole 21 is provided with expansion section 212 at the end near door body 2 ends; Flange 33 is engaged in the expansion section 212, so that an end of hinge shaft sleeve 3 overlap joint is in the side near door body 2 ends of installing hole 21.
As shown in Figure 2; According to one embodiment of present invention, hinge shaft sleeve 3 has crossed beam trunking 34 and runs through the perisporium of hinge shaft sleeve 3 and extend on the whole length of hinge shaft sleeve 3 along axial (being above-below direction among Fig. 2) of hinge shaft sleeve 3 along radially (being along the radial direction of hinge shaft sleeve 3 among Fig. 3) of hinge shaft sleeve 3.Accordingly, hinge axis 41 is for having the centre bore 42 that connects vertically, and hinge axis 41 also forms the mistake line opening (not shown) corresponding with crossed beam trunking 34 on its perisporium.
As illustrated in fig. 1 and 2, when wire harness 5 need pass from the end of refrigerator door 2, can be arranged in advance in the installing hole 21, wait to foam after installing hole 21 can pass the end of a body 2.Because wire harness 5 ends have the plug 51 of certain size, so wire harness 5 can not stretch into and pass the inside of the two from the two ends of hinge shaft sleeve 3 and hinge axis 4.Yet can solve the problem that wire harness 5 passes hinge shaft sleeve 3 and hinge axis 4 inside through crossed beam trunking 34 and mistake line opening.
Thus; The refrigerator of the embodiment of the invention; When wire harness 5 need pass body 2; Wire harness 5 can and be crossed the line opening and stretch into and pass the inside of the two from the radial direction of hinge shaft sleeve 3 and hinge axis 41 through crossed beam trunking 34; Finally pass a body 1; The end that can be omitted in a body 2 on the one hand is set like this for wire harness 5 outlet is set separately, therefore simplified the manufacturing process of door body; On the other hand, wire harness 5 can not caused wire harness 5 impaired by hinge shaft sleeve 3 compressings.
Below the simple door body installation method of describing according to the refrigerator of the embodiment of the invention.
At first, the body 2 of the door with installing hole 21 is provided, and the inwall of installing hole 21 is provided with locating slot;
Then, the location convex tendon 31 of hinge shaft sleeve 3 with after the locating slot of door body 2 installing holes 21 aligns, is made hinge shaft sleeve 3 cooperating in the insertion installing hole 21 through location convex tendon 31 and locating slot; With
At last, the hinge axis of hinge seat 4 41 is inserted in the hinge shaft sleeves 3 so that a door body 2 is pivotably mounted on the refrigerator body 1.
When refrigerator wire harness 5 need pass in door body 2, above-mentioned door body method also comprised:
Before hinge shaft sleeve 3 is inserted installing hole 21, earlier refrigerator wire harness 5 is put into hinge shaft sleeve 3 inside (being mating holes 35) through wire harness groove 34, again hinge shaft sleeve 3 is inserted in the installing hole 21; With
Before hinge axis 41 is inserted hinge shaft sleeve 3, earlier refrigerator wire harness 5 is put into hinge axis 41 inside (being centre bore 42) through the wire harness opening, the hinge axis 41 with hinge seat 4 inserts in the hinge shaft sleeve 3 again.
