[specific embodiment]
Embodiment one:
As Fig. 1,2, shown in 3, a kind of water tub of washing machine fixture 10, be used for fixing steel ladle 20 and back shroud 30, this fixture 10 comprises set bolt 11, on the described set bolt 11 by after be arranged with first pad 16 forward successively, spring 14, second pad 13 and support member 12, the leading section of described set bolt 11 is by being threaded onto on the steel ladle 20, support member 12 is located between steel ladle 20 and the back shroud 30, first pad 16, the spring 14 and second pad 13 are located at back shroud 30 outsides, but also are provided with the position-limit mechanism of control spring 14 maximum compressibility between described first pad 16 and second pad 13.
Position-limit mechanism adopts locating sleeve 15 in the present embodiment, and locating sleeve 15 is set in and is positioned at spring 14 inside on the set bolt 11, and the length of locating sleeve 15 is less than the drift of spring 14, the length during greater than spring 14 maximum compression.Certainly, locating sleeve 15 also can be set in spring 14 outsides, as long as satisfy the drift of the length of locating sleeve 15 less than spring 14, the length during greater than spring 14 maximum compression gets final product.
Aforesaid water tub of washing machine fixture 10 mainly works to connect steel ladle 20 and back shroud 30.It is made up of set bolt 11, support member 12, second pad 13, spring 14, locating sleeve 15 and first pad 16, mainly works to support and cushion described steel ladle 20.There are some places that the double-screw bolt portion 21 of described set bolt 11 is installed on the described steel ladle 20, work to tighten described set bolt 11.
As shown in Figure 4, described back shroud 30 is parts of the shell of washing machine, on the described back shroud 30 through hole 31 is arranged, and through hole 31 is made up of circle portion 311 and cylindrical portion 312.
When assembling described water tub of washing machine fixture 10 as shown in Figure 1,1. earlier described first pad 16 is packed on the described set bolt 11, the internal diameter of described first pad 16 is less than the nut diameter of described set bolt 11, the external diameter of described first pad 16 is greater than the race diameter of described spring 14, and purpose works to support described spring 14.2. more described locating sleeve 15 is packed on the described set bolt 11, locating sleeve 15 has certain intensity, and its inner ring diameter is greater than described second pad, 13 inner ring diameters.3. more described spring 14 is packed on the described set bolt 11.4. more described second pad 13 is packed on the described set bolt 11, the race diameter of described second pad 13 is greater than the diameter of the round portion 311 of described back shroud 30.5. more described support member 12 is packed on the described bolt, described support member 12 is the spaces of filling described steel ladle 20 and described back shroud 30, and its maximum outside diameter is less than the diameter of the round portion 311 of back shroud 30.Described support member 12 keeps certain distance L with described second pad 13.
