Description
Technical field
The utility model relates to spring art, is specifically related to a kind of latch plate of Multi-stage damping.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work.There is deformation under external force with the part that elastic material is made, restore to the original state again after removing external force.Also " spring " is made.General spring steel is made.The kind complexity of spring is various, divides by shape, mainly contains helical spring, spiral spring, leaf spring, heterotypic spring etc.
Although Spring Industry is a little industry in the middle of whole manufacturing industry, its effect played is definitely immeasurable.Industrial manufacturing industry, the automotive industry of country will be accelerated development, and based on part, one of component Spring Industry just more need the advanced phase of a development, the fast development of national whole industry could be adapted to.In addition, the expansion of spring product scale kind, the raising of quality level are also the needs of the machinery Replacement replacement and the needs of matched host machine performance raising, and therefore, the development of whole National Industrial, spring product plays an important role.
In real process, often run into and need low resistance a kind of early stage, the later stage needs the spring of high damping, and this spring does not often reach requirement due to the reason of single damping.
Model utility content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, the latch plate of a kind of Multi-stage damping reasonable in design, easy to use, the mode that it adopts multiple spring to be socketed, by the flexible effect of multistage spring during extruding, forms the damping of gradient, and it has easy to use, simple to operate, with low cost, the feature such as practical.
For achieving the above object, the technical solution adopted in the utility model is:
The latch plate of a kind of Multi-stage damping described in the utility model, comprise base plate, one-level cover plate, one-level spring, two-level spring and three grades of springs, one-level spring is provided with between described base plate and one-level cover plate, described one-level both ends of the spring welds with base plate and one-level cover plate respectively, two-level spring is provided with in described one-level spring, three grades of springs are provided with in two-level spring, described two-level spring and three grades of springs are all welded on base plate, the length of described one-level spring, two-level spring and three grades of springs reduces successively, and diameter also reduces successively.
The elasticity coefficient of described one-level spring, two-level spring and three grades of springs increases successively.
Described two-level spring upper end is provided with secondary cover plate, and adopts the mode of welding to connect, and described three grades of spring upper end are provided with three grades of cover plates, and adopts the mode of welding to connect.
Adopt after said structure, the utility model beneficial effect is: its mode of adopting multiple spring be socketed of the utility model, the flexible effect of multistage spring during by extruding, form the damping of gradient, and it has easy to use, simple to operate, with low cost, the feature such as practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, base plate; 2, one-level cover plate; 3, one-level spring; 4, secondary cover plate; 5, two-level spring; 6, three grades of cover plates; 7, three grades of springs.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the latch plate of a kind of Multi-stage damping described in the utility model, comprise base plate 1, one-level cover plate 2, one-level spring 3, two-level spring 5 and three grades of springs 7, one-level spring 3 is provided with between described base plate 1 and one-level cover plate 2, described one-level spring 3 two ends are welded with base plate 1 and one-level cover plate 2 respectively, two-level spring 5 is provided with in described one-level spring 3, three grades of springs 7 are provided with in two-level spring 5, described two-level spring 5 and three grades of springs 7 are all welded on base plate 1, described one-level spring 3, the length of two-level spring 5 and three grades of springs 7 reduces successively, diameter also reduces successively.
The elasticity coefficient of described one-level spring 3, two-level spring 5 and three grades of springs 7 increases successively.
Described two-level spring 5 upper end is provided with secondary cover plate 4, and adopts the mode of welding to connect, and described three grades of spring 7 upper ends are provided with three grades of cover plates 6, and adopts the mode of welding to connect.
The utility model in use; one-level cover plate pressurizes; one-level spring receives extruding and moves down; in time being expressed to secondary cover plate; because the strength of pressure effect is enough large; impel one-level cover plate to push secondary cover plate to continue to move down; now the damping of spring comes from the acting in conjunction of one-level spring and two-level spring; form the growth of a gradient; also be same principle for three grades of springs; design, this way can be protected by more than enough one-level spring, prevents due to the excessive damage to spring of pressure.
The features such as its mode of adopting multiple spring to be socketed of the utility model, by the flexible effect of multistage spring during extruding, form the damping of gradient, and it has easy to use, simple to operate, with low cost, practical.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
