Abstract
The utility model discloses an internal thread anti-loosing structure of a reactor, which comprises a bolt (3), an anti-loosing nut (4) and a limit lever (5); a bolt (3) groove, a through hole in the middle of the anti-loosing nut (4) and the limit lever (5) are in polygonal shapes, and the limit lever (5) can pass through the through hole of the anti-loosing nut (4) and is inserted into the bolt (3) groove; the anti-loosing nut (4) is provided with an external thread; and the thread directions of the anti-loosing nut (4) and the bolt (3) are opposite. The utility model provides the internal thread anti-loosing structure of the reactor which is convenient, reliable and convenient to detach.
Description
Technical field
The utility model relates to the reactor engineering technical field, particularly a kind of reactor internal thread anti-loose structure.
Background technique
In reactor, use in a large number when connecting between the structural member and be threaded, what be threaded lockingly becomes very important problem.Owing to reasons such as vibration cause thread looseness easily, the serious links such as bolt or nut that then can take place fall, and cause potential safety hazard to reactor, bring economic loss in reactor operation.And the locking most employing that generally is threaded in the reactor current heap destroys the mode of screw thread, as intermittent welding or towards riveting, but can't adopt this mode at the position of ask for something field-strip.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of easy reactor internal thread anti-loose structure reliable, for convenience detach is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of reactor internal thread anti-loose structure, comprise bolt, lock nut and position-limited lever, through hole in the middle of bolt indentation, the lock nut, the shape of position-limited lever are polygonal, and position-limited lever can pass the lock nut through hole and be inserted in the bolt indentation, and the thread rotary orientation of lock nut and bolt is opposite.
The utility model is all right: described bolt indentation and position-limited lever be shaped as regular hexagon, being shaped as by 2 regular hexagons of lock nut through hole forms for staggered 30 °.
Compared with prior art, the beneficial effects of the utility model are: the utility model is the fabricated structure of bolt, lock nut and position-limited lever, utilize the bolt characteristics opposite with the lock nut rotation direction, it is locking that position-limited lever is play a part in the centre, can prevent the bolt rotation; Wherein position-limited lever moves up and down very easily, greatly facilitates dismounting, and anti-loosing effect is safe and reliable.

1 little grid plate header, 2 big grid plate headers, 3 bolts, 4 lock nuts, 5 position-limited levers
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
The sectional view of a kind of reactor internal thread anti-loose structure as shown in Figure 1, in the present embodiment, this structure is used for being threaded of the medium and small grid plate header 1 of reactor and big grid plate header 2, connected piece is little grid plate header 1 and big grid plate header 2, and little grid plate header 1 is connected by this structure with big grid plate header 2.This structure is a fabricated structure, mainly comprise bolt 3, lock nut 4 and position-limited lever 5, through hole in the middle of bolt 3 grooves, the lock nut 4, the shape of position-limited lever 5 are polygonal, and position-limited lever 5 can pass lock nut 4 through holes and be inserted in bolt 3 grooves, and the thread rotary orientation of lock nut 4 and bolt 3 is opposite.Present embodiment is to be dextrorotation with bolt 3, and lock nut 4 is outside thread and left-handed design, and simultaneously little grid plate header 1 and big grid plate header 2 all need process threaded coupling correspondingly.Bolt 3 grooves and position-limited lever 5 be shaped as regular hexagon, the shape of through holes of lock nut 4 is to be formed for staggered 30 ° by 2 regular hexagons, as shown in Figure 2, can be easy to make the position centering of lock nut 4 through holes and bolt 3 grooves like this, position-limited lever 5 can be by polygonal through hole inserting bolt 3 grooves of lock nut 4.Because bolt 3 is opposite with lock nut 4 rotation directions, position-limited lever 5 works in the centre and reaches the locking purpose of bolt 3.
Its medium and small grid plate header 1 and big grid plate header 2 are by straight mouthful of location, avoid bolt 3 to bear shearing force like this, on the endoporus of little grid plate header 1, processed the left-handed thread that lock nut 4 is installed, after little grid plate header 1 is installed on the big grid plate header 2, tighten fixing with bolt 3, lock nut 4 is installed and is made its inner polygon hole and the polygonal centering of bolt 3 grooves, insert position-limited lever 5, realize locking purpose.
Claims (2)
1. reactor internal thread anti-loose structure, it is characterized in that, comprise bolt (3), lock nut (4) and position-limited lever (5), through hole in the middle of bolt (3) groove, the lock nut (4), the shape of position-limited lever (5) are polygonal, and position-limited lever (5) can pass lock nut (4) through hole and be inserted in bolt (3) groove, lock nut (4) is an outside thread, and the thread rotary orientation of lock nut (4) and bolt (3) is opposite.
2. a kind of reactor internal thread anti-loose structure according to claim 1 is characterized in that, described bolt (3) groove and position-limited lever (5) be shaped as regular hexagon, being shaped as by 2 regular hexagons of lock nut (4) through hole forms for staggered 30 °.
