The invention provides the double-bolt connecting mechanism which has the advantages of simple structure, reasonable design, easy assembly and disassembly, firm connection and long service life.
Description
Technical Field
The invention belongs to the technical field of connecting pieces, and particularly relates to a double-bolt connecting mechanism.
Background
The bolt is a fastener consisting of a head part and a screw rod, needs to be matched with a nut and is used for fastening and connecting two parts with through holes, the connection form is called bolt connection, if the nut is screwed off from the bolt, the two parts can be separated, and therefore the bolt connection belongs to detachable connection.
At present, two connecting portion that mutually support are fixed through a bolted connection mostly, adopt single bolted connection, when two connecting portion receive the exogenic action, can produce relative rotation between two connecting portions, connect insecurely, in order to overcome single bolted connection's defect, adopt two bolt connection structure now to appear, however, current two bolt structure is only single bolt's simple stack, the screw thread of two bolts is to the same, when two connecting portion receive the exogenic action, the trend of becoming loose can appear simultaneously in two bolts, and it is long-lasting, the insecure problem of connection all can appear in two bolts.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the double-bolt connecting mechanism which has the advantages of simple structure, reasonable design, easy assembly and disassembly, firm connection and long service life.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
the double-bolt connecting mechanism comprises a first connecting piece, a second connecting piece, a positive bolt and a negative bolt, wherein the first connecting piece and the second connecting piece are tightly connected through the positive bolt and the negative bolt, and the thread of the positive bolt is tightly matched with the thread of the negative bolt.
Preferably, the positive bolt and the negative bolt are both provided with L-shaped grooves, and the L-shaped grooves are used for inserting a spanner and rotating the positive bolt and the negative bolt.
Preferably, the front bolt and the back bolt are both provided with positioning holes, and positioning pins penetrate through the positioning holes.
Preferably, the front bolt is provided with 2 positioning holes, the back bolt is provided with 2 positioning holes, and the positioning holes in the front bolt correspond to the positioning holes in the back bolt in position.
Preferably, the number of the positioning pins is 2.
Preferably, locating pin cap is equipped with to locating pin one end, and the other end is equipped with the locating pin through-hole, has the locating pin bolt to pass in the locating pin through-hole, and the locating pin bolt can prevent that the locating pin from droing, realizes stable connection.
The invention has the beneficial effects that: the invention provides the double-bolt connecting mechanism which has the advantages of simple structure, reasonable design, easy assembly and disassembly, firm connection and long service life.

FIG. 1 is an exploded view of example 1 of the present invention;
FIG. 2 is a schematic structural view of embodiment 1 of the present invention;
FIG. 3 is an exploded view of example 2 of the present invention;
in the above drawings: 1. a first connecting member; 2. a second connecting member; 3. a positive bolt; 4. a counter bolt; 5. an L-shaped groove; 6. positioning holes; 7. positioning pins; 8. a locating pin cap; 9. a positioning pin through hole; 10. and (6) positioning pin inserting pins.
Detailed Description
The present invention will be further described in the following detailed description with reference to the drawings.
Example 1
As shown in fig. 1 and 2, the double-bolt connecting mechanism includes a first connecting piece 1, a second connecting piece 2, a positive bolt 3 and a negative bolt 4, wherein the first connecting piece 1 and the second connecting piece 2 are tightly connected through the positive bolt 3 and the negative bolt 4, the thread of the positive bolt 3 is tightly matched with the thread of the negative bolt 4, the positive bolt 3 and the negative bolt 4 are both provided with an L-shaped groove 5, the L-shaped groove 5 is used for inserting a wrench to rotate the positive bolt 3 and the negative bolt 4, the positive bolt 3 and the negative bolt 4 are both provided with positioning holes 6, positioning pins 7 penetrate through the positioning holes 6, the positive bolt 3 is provided with 2 positioning holes 6, the negative bolt 4 is provided with 2 positioning holes 6, the positioning holes 6 on the positive bolt 3 correspond to the positioning holes 6 on the negative bolt 4, and the positioning pins 7 are 2 in total.
Example 2
As shown in fig. 3, this embodiment is substantially the same as embodiment 1, except that one end of the positioning pin 7 is provided with a positioning pin cap 8, the other end is provided with a positioning pin through hole 9, a positioning pin plug 10 passes through the positioning pin through hole 9, the positioning pin bolt 10 is composed of an elastic stainless steel sheet with an opening at one end and a closed end, the width of the opening end of the positioning pin bolt 10 is larger than the diameter of the positioning pin through hole 9, when in use, the width of the opening end of the positioning pin plug pin 10 is reduced by pinching the positioning pin plug pin 10 by hand, after the positioning pin plug pin is inserted into the positioning pin through hole 9, the positioning pin plug pin 10 is restored to the normal state, at the moment, because both ends of the positioning pin plug pin 10 are larger than the diameter of the positioning pin through hole 9, therefore, the locating pin bolt 10 is clamped in the locating pin through hole 9 and cannot fall off, the looseness of the double-bolt connecting mechanism caused by vibration is effectively prevented, and the connecting stability is enhanced.
The above description is only an embodiment of the present invention, but the structural features of the present invention are not limited thereto, and the present invention can be applied to similar products, and any changes or modifications within the scope of the present invention by those skilled in the art are covered by the present invention.
