Specific embodiment
Below with reference to specific embodiments and the drawings, the present invention is described in detail.
Referring to Fig. 5, the sectional structure of existing inner locking type pipe fitting is illustrated as reference, it is existing because being provided with use
In the lock hole that lock pin uses, there are biggish leakage hidden danger, as a comparison, can obviously distinguish locking structure of the present invention
It does not exist together.
The inner locking type fitting structure schematic diagram for showing the link mechanism device of the embodiment of the present invention referring to FIG. 1-2, includes
Blocking 1, fastening screw 3, connecting rod 4, connects handle 5, driver plate 6, pin 7, O-ring 8, spiral pedestal 9, fixing screws 10, four at lock ring 2
Way pipe fitting 11 and positioning pin 12 form, and annular groove 11a is equipped in 11 flange of four-way pipe fitting, and blocking 1 seals 11 method of four-way pipe fitting
Flange aperture is cased with O-ring 8 in blocking 1, connects handle 5 in 1 upside setting of blocking, connects handle 5 for connecting means for placing plug, cover on connecing handle 5
There is driver plate 6, pin 7 is fixed on driver plate 6, pin 7 entangles one end of connecting rod 4, and the other end of connecting rod 4 connects fastening screw 3,
The lower end of fastening screw 3 connects lock ring 2, and the horizontal position of lock ring 2 is just the horizontal position of annular groove 11a, and lock ring 2 passes through tight
Gu screw 3 links together connecting rod 4, connecting rod 4 has to be connected with driver plate 6, i.e., driver plate 6 is connected to lock ring 2, and controls lock ring 2
Movement.
Such as Fig. 3, driver plate 6 is arranged above spiral pedestal 9, and the upper center position of blocking 1 is arranged in spiral pedestal 9, Gu
The effect for determining screw 10 is fixed spiral pedestal 9.
Such as Fig. 2-3,1 upper surface is being blocked, four lock rings 2 are uniformly distributed, accordingly, there are four connecting rods 4, and there are four pins
7, four pins 7 all cover on driver plate 6, both can correspondingly other three locks by describing the working principle of a lock ring 2
The case where ring, Fig. 2-3 illustrate the pin of 1 upper surface of blocking and the distribution situation of connecting rod.
If Fig. 3 is equipped with a snap ring 51 in the top of driver plate 6, snap ring 51, which is stuck in, to be connect on handle 5, and snap ring 51 can prevent from dialling
Disk 6 up moves.
7 sets of pin are equipped with an annular base slot 91 in driver plate 6, in spiral pedestal 9, and annular base slot 91 can limit
Pin 7 can only be moved along annular base slot 91.
On one end set pin 7 of connecting rod 4, the purpose is to allow one end of connecting rod 4 that pin 7 is followed to move.
Lock ring 2 setting sliding square groove 13 in, as Fig. 3 downside figure in show.Sliding square groove 13 defines lock ring 2
It can only be moved along sliding square groove 13, i.e., lock ring 2 is inserted into annular groove 11a by sliding square groove 13.
Interaction relation: it rotates by a certain angle when the rotation counterclockwise of revolving dial 6 forces pin 7 to follow, one end of connecting rod 4 is moved
It is dynamic, then lock ring 2 is pushed to be inserted into annular groove 11a again.
When lock ring 2 is inserted into annular groove 11a, the direction of connecting rod 4 is identical as the direction of square groove 13.
Such as the figure below Fig. 3, in the case where lock ring 2 is inserted into annular groove 11a state, the position of connecting rod 4 is the position 4a, pin 7
Position be the position 7a, same principle, other three pins are also by this structural arrangement.
The angle rotatable stroke of driver plate 6 is between 45 ° -48 °, and the present embodiment is set as 47.51 °, in angle rotatable
Stroke can reach locking effect between 45 ° -48 °, be more than this range, then operating distance is too long, be less than this range,
2 insertion depth of lock ring be will lead to than shallower, locking effect is bad.
When the needs of lock ring 2 come out from annular groove 11a, i.e., unlocking state, the position of connecting rod 4 are the position 4b, pin 7
Position be the position 7b, pin 7 has rotated 47.51 ° at this time, and lock ring 2 is x in the distance that sliding square groove 13 moves, herein,
Driver plate 6, which is stuck, to be rotated, and can limit the stroke of lock ring 2 in this way, as long as lock ring 2 completes locking.
Be the enlarged drawing of Fig. 3 centre circle M such as Fig. 4, when connecting rod 4 by driver plate 6 rotate by a certain angle and can be by connecting rod 4
It is locked in 9 top of spiral pedestal, and can also prevent the mobile lock-off of connecting rod 4, pin 7 is fixed on driver plate 6, and can be in spiral pedestal
9 annular base slot 91 rotates by a certain angle, and spiral pedestal 9 is fastened on blocking ontology with the fixing screws 10 of handle 5 are connect.
Such as Fig. 2, the setting of positioning pin 12 is mainly used to the component of fixed 1 top of blocking, is mainly formed in blocking 1
Slide the clamping plate of 13 two sides of square groove.
Blind plate is usually also set up above interior locking-type pipe fitting.
O-ring 8 is located between blocking 1 and 11 flange of pipe fitting, plays the role of barrier 1 upper and lower medium of blocking
The work flow of the present apparatus is: connecing handle 5 and connect with dedicated means for placing plug, drives driver plate 6 to rotate counterclockwise to bottom, driver plate 6 exists
It is rotated in spiral pedestal 9 in 47.510 angles, rotates to horizontal position, the mobile certain stroke of connecting rod 4 is promoted in flange groove, tightened
Fastening screw 3 on connecting rod 4 prevents connecting rod 4 from deviating from flange groove, ensures the safety of blocking 1, and the work of lower blocking is completed.
The product will be widely used in the construction of petroleum and petrochemical industry, city gas pipeline on-line production aperture, this profession produces
What product were engaged in be all petroleum, chemical industry, in gas industry inflammable, explosive, poisonous and harmful medium pipeline construction operation, it prevents
Because using lockpin-type flange to will cause sealing element aging leakage accident is generated, jeopardizes the people's lives and property safety.
The invention of this product by pair safety in production have special meaning, be that China's modern times pipeline construction equipment develops
Another new results have good application prospect, are highly desirable to promote and apply, it will be widely used in the combustion of petroleum and petrochemical industry city
In the pipe first-aids operation such as gas.
Above disclosed is only a preferred embodiment of the present invention, cannot limit the power of the present invention with this certainly
Sharp range, therefore equivalent changes made in accordance with the claims of the present invention, are still within the scope of the present invention.
