Description
Technical field
The utility model belongs to technical field of fastening, and in particular to a kind of crane span structure system high-performance spring nut.
Background technology
Spring nut include spring and nut block, traditional spring nut is slotted in nut block, by spring inlay card into
It goes, then the notch of nut block is made to deform, reduce using moment strong high pressure, thus spring and nut block just secure.So
And in this spring nut, spring is easily broken off, and entire spring nut is caused to scrap, and can not be replaced, and is wasted very much.
Utility model content
In order to make up for the deficiencies of the prior art, the utility model provides a kind of skill of crane span structure system high-performance spring nut
Art scheme.
A kind of crane span structure system high-performance spring nut, including spring and nut block, it is characterised in that the spiral shell
Mother tuber includes the first nut block and the second nut block, and the end face of first nut block is set as stepped hole, and the is opened up in hole
One nut block internal thread, second nut block open up with the corresponding second nut block internal thread of the first nut block internal thread,
The second nut block side opens up the spring groove of annular, and the notch of the spring groove is set as closing up shape, the second nut block with
Spring groove is boundary, higher than spring slot part diameter be more than less than spring slot part diameter, wherein, less than spring slot part side
Face opens up external screw thread, and second nut block is threaded on the stepped hole of first nut block, one end of the spring
It is set in second nut block, wherein, spring end is embedded in the spring groove.
A kind of crane span structure system high-performance spring nut, it is characterised in that the one end of the spring far from nut block
Washer is set.
A kind of crane span structure system high-performance spring nut, it is characterised in that open the first nut block bottom surface both sides
If indent, be staggered one group of detent projection in the indent.
A kind of crane span structure system high-performance spring nut, it is characterised in that the spring groove location is higher than described the
The upper surface of one nut block.
A kind of crane span structure system high-performance spring nut, it is characterised in that second nut block is in spring groove pair
Answer position that multiple buckles are set.
It is the utility model is designed reasonably, simple in structure, it, can only more during spring breaking down using the nut block of split structure
The second nut block is changed, saves use cost, it is very convenient.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the first nut block structure diagram in the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of crane span structure system high-performance spring nut, including spring 1 and nut block, the nut block
For separate structure, including the first nut block 2 and the second nut block 3, the end face of first nut block 2 is set as stepped hole
200, the first nut block internal thread is opened up in hole, and second nut block 3 opens up and the first nut block internal thread corresponding
Two nut block internal threads, 3 side of the second nut block open up the spring groove 300 of annular, the notch setting of the spring groove 300
To close up shape, the second nut block 3 is boundary with spring groove 300, and the diameter higher than 300 part of spring groove is more than less than spring slot part
Diameter, wherein, open up external screw thread less than 300 surface of spring groove, second nut block 3 is threaded in described first
On the stepped hole 200 of nut block 2, one end of the spring 1 is set in second nut block 3, wherein, 1 end of spring is embedding
It is located in the spring groove 300.
In the utility model, one end setting washer 4 of the spring 1 far from nut block.
In the utility model, the 2 bottom surface both sides of the first nut block open up indent 201, are staggeredly set in the indent 201
Put one group of detent projection 202.
In the utility model, 300 position of spring groove is higher than the upper surface of first nut block 2.
In the utility model, second nut block 3 sets multiple buckles 5 in 300 corresponding position of spring groove.
It is the utility model is designed reasonably, simple in structure, it, can only more when spring 1 damages using the nut block of split structure
The second nut block 3 is changed, saves use cost, it is very convenient.
