Abstract
The utility model discloses a kind of fixing device, comprise step flange bolt, spacing circle and packing ring, spacing snare is on the step of step flange bolt, packing ring is placed on the step end of the blue bolt of benching tunnelling method, and spacing circle is that one or more in plastics, rubber or non-ferrous metal are made, and advantage is: the spacing circle that adopts plastics, rubber or non-ferrous metal to make, weight is reduced greatly, effectively reduce like this gross weight of product, reduced unnecessary heavy burden, make the utilization efficiency of the energy higher.Owing to adopting non-steel material to manufacture by more processing technology, can effectively improve the utilization ratio of material, reduce costs, more processing technology is also beneficial to large-scale production.
Description
Technical field
The utility model relates to a kind of fixing device.
Background technique
In bolton, often can use spacing circle, existing spacing circle is all to adopt steel material, and weight is heavier; when especially spacing circle is larger, weight can be multiplied; such structure can cause product weight heavier, can increase unnecessary heavy burden, reduces the utilization efficiency of the energy.And the spacing circle of steel generally need to adopt process for machining according to size, lower to the utilization ratio of material like this, cause cost higher, be also unfavorable for mass production simultaneously.
Model utility content
The utility model provides the lighter cost of a kind of weight the lower fixing device that is more conducive to large-scale production.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fixing device, comprise step flange bolt, spacing circle and packing ring, and spacing snare is on the step of step flange bolt, and packing ring is placed on the step end of the blue bolt of benching tunnelling method.
Spacing circle is that one or more in plastics, rubber or non-ferrous metal are made.
Utilization due to technique scheme, the utility model compared with prior art, the advantage having is: the spacing circle that adopts plastics, rubber or non-ferrous metal to make, weight is reduced greatly, effectively reduce like this gross weight of product, reduced unnecessary heavy burden, made the utilization efficiency of the energy higher.Owing to adopting non-steel material to manufacture by more processing technology, can effectively improve the utilization ratio of material, reduce costs, more processing technology is also beneficial to large-scale production.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is mechanical analysis figure of the present utility model.
In above accompanying drawing: 1, step flange bolt, 2, spacing circle, 3, packing ring, 4, fixed block.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is further described.
As shown in Fig. 1 to 2, a kind of fixing device of the present utility model, comprise step flange bolt 1, spacing circle 2 and packing ring 3, the step of step flange bolt 1 is passed after the fixed hole of fixed block 4, spacing circle 2 is placed on the step of step flange bolt 1, packing ring 3 is placed on to the step end of step flange bolt 1, packing ring 3 flushes with the step end face of step flange bolt 1, plays the effect that bolt clipping forcee is distributed to fixed surface again.
Wherein, spacing circle 2 is made for one or more in plastics, rubber or non-ferrous metal, can be by processing technology manufacture moulding such as injection moulding, foaming or die casting.
The spacing circle 2 that adopts plastics, rubber or non-ferrous metal to make, reduces weight greatly, effectively reduces like this gross weight of product, has reduced unnecessary heavy burden, makes the utilization efficiency of the energy higher.Owing to adopting non-steel material to manufacture by more processing technology, can effectively improve the utilization ratio of material, reduce costs, more processing technology is also beneficial to large-scale production.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
