Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is a kind of Multifunctional bolt nut body.
The application method of this example:
A kind of Multifunctional bolt nut body, including screw bolt and nut 5 are provided, the bolt includes bolt head 1, molding
In connecting flange 8, the bolt neck 2 being molded on connecting flange 8,6 and of shank of bolt that is molded on bolt neck 2 on bolt head 1
Waterproof construction 4, the bolt head 1 are provided with the first internal screw thread 7 with respect to the side of bolt neck 2, the connecting flange 8 it is straight
Diameter is greater than 1 diameter of bolt head, and 2 diameter of bolt neck is less than 6 diameter of shank of bolt, is provided with outer spiral shell on the shank of bolt 6
Line 3, the external screw thread 3 and 7 thread rotary orientation of the first internal screw thread are on the contrary, the waterproof construction 4 includes the first sealing ring 41, the
Two sealing rings 42 and gasket 43, first sealing ring 41 is glued to the side that connecting flange 8 is connected with bolt neck 2, described
The second sealing ring 42 and gasket 43 be arranged on shank of bolt 6, gasket 43 is embedded in 42 outside circumference of the second sealing ring, described
Nut 5 be threadedly connected on bolt neck 6.
Wherein, first internal screw thread 7 can be threaded connection with bolt, and the punching depth of the first internal screw thread 7 is less than bolt head 1
Length.The design of punching depth is the intensity in order to guarantee bolt head 1.
Wherein, the external screw thread 3 is divided to two sections to be arranged on shank of bolt 6.
Wherein, first sealing ring 41 and the second sealing ring 42 are all made of rubber and are made, 42 diameter of the first sealing ring
Less than 8 diameter of connecting flange, through-hole diameter and the 3 crest diameter phase of external screw thread of the first sealing ring 41 and the second sealing ring 42
Match.Rubber material waterproof, the design of the first sealing ring 42 is smaller than connecting flange 8, and the first sealing ring 42 can be connected flange 8 completely
It compresses, plays completely waterproof effect.
Wherein, for 5 length of nut less than the length of a section external screw thread 3, nut 5 is provided with second internal screw thread
51.5 length of nut control to be less than 3 length of single-unit external screw thread guarantee nut can completely tight thread be connected on bolt.
Wherein, second internal screw thread 51 perforation is arranged in 5 any one quadrangle side middle position of nut.In second
Screw thread 51 can be used to the lubricants such as clamping screw and injection lubricating oil.
The application method of this example:
It skids when the abrasion of 1 corner of bolt head occurs in bolt, so that when the case where bolt can not be dismantled normally, we can be with
Using plain bolt, by screw thread, threadingly direction rotates the first internal screw thread 7 of precession bolt head 1 to plain bolt, and can not tear open
The bolt thread connection unloaded, when plain bolt cannot precession again when, we select to rotate plain bolt again, due to can not
The hand of spiral of the external screw thread 3 of the bolt of disassembly and the first internal screw thread 7 on the contrary, bolt is allowed smoothly to be removed,
The external screw thread 3 of bolt is divided into two sections, is that can achieve self-locking effect in precession fastening article.
The second internal screw thread 51 being arranged on nut 5 can increase the tightness of bolt-nut mechanism, when nut 5 and bolt spiral shell
Line be connected on fastener can not activity when, a bolt or screw can be threadedly coupled by the second internal screw thread 51, in second
Screw thread passes through 51 and leads to 5 inner wall of nut, and bolt or screw can arrive to external screw thread 3 or shank of bolt 6, so that bolt is not easy to loosen.If
Bolt has got rusty, and when can not fall bolt by using reversed Bolt dismantling, we can also pass through the second internal screw thread to nut 5
51 injection liquid, the lubricating oil such as lubricating oil can be slipped on external screw thread 3, and lubricating oil can reduce rubbing for bolt and fastening article
Resistance is wiped, slows down abrasion, bolt is easily disassembled.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
