Abstract
The utility model relates to the field of equipment for sealing petroleum discarded wells, in particular to an encrypting lock well-sealing device. The encrypting lock well-sealing device comprises an encrypting lock and a well plug and is characterized in that the encrypting lock structurally comprises a base, an upper cover, a locking spring, a snap ring, a positioning nut and a positioning bolt. One end of the base is sleeved with the upper cover, the locking spring is arranged in the upper cover, the snap ring is arranged in the center of the locking spring, a flanging-outward edge is arranged at the outer end of the locking spring, the flanging-outward edge is bucked with an flanging-inward edge of the upper end of the base, the tail portion of the positioning bolt penetrates through the upper cover, the base and the locking spring in sequence and then is connected with the snap ring, a first locking ring and a second locking ring are arranged on the positioning nut, and an unlocking slot is formed between the first locking ring and the second locking ring. When the encrypting lock well-sealing device is in the unlocking state, the unlocking slot right corresponds to a positioning ring at the end of the base; when the encrypting lock well-sealing device is in the locking state, the first locking ring and the second locking ring are located in a slot of the positioning ring. Compared with the prior art, the encrypting lock well-sealing device has the advantages that the encrypting level is higher, the lock is prevented from being eroded by rain, snow, wind and sand in the natural environment, and the encrypting lock can remain valid for a long time.
Description
Technical field
The utility model relates to oil and throws aside well shut-in well apparatus field, the particularly locked well device of a kind of encryption function.
Background technology
Well-sealing device with encryption function is a kind of blowout preventer of controlling for the ground shutoff, comprise that encryption lock and well are stifled, to be widely used in the shut-in well of throwing aside well, administering well in the oil field capital equipment in processing, the effect that its function also has pressure measurement, bleeds off pressure except shut-in well, its theftproof performance of General Requirements is reliable, Environmental Safety, be difficult for destroyed.The normally used burglarproof well plugging device in oil field is comprised of one hidden lock and several groups of coded locks at present, and its advantage is simple in structure, and volume is little, its weak point is that theftproof performance is unreliable, hidden lock is actual is outside exposed, and when being found by the oil stealer, loss can't be avoided.
Summary of the invention
The purpose of this utility model is to provide the locked well device of a kind of encryption function, overcomes the deficiencies in the prior art, by the structure design of encryption lock, obtains more hidden, security classification is higher, in antitheft, can also avoid the erosion of natural environment to lock body, encryption lock can be remained valid for a long time.
For achieving the above object, the utility model adopts following technical scheme to realize:
The locked well device of encryption function, comprise that encryption lock and well are stifled, described encryption lock structure comprises base, upper cover, snap, snap ring, setscrew nut and positioning bolt, one end overcoat upper cover of base, be provided with snap in upper cover, the heart section of snap is provided with snap ring, and the outer end of snap is provided with outer turning edge, turn edge outward with the base upper end in turn edge and be interlocked, the afterbody of positioning bolt is connected with snap ring after running through successively upper cover, base, snap;
Positioning bolt is provided with setscrew nut, and setscrew nut is provided with lock ring one and lock ring two, between lock ring one and lock ring two, is provided with the groove of unblanking, during opening, and the just in time centring ring of corresponding base end of groove of unblanking; During locking states, lock ring one or lock ring two are positioned at the fluting place on centring ring.
Described setscrew nut and positioning bolt, as lock core, are distributed with 1 ~ 10 group on the upper cover circumference.Lock core quantity preferred amount is 3 ~ 5 groups.
Cover on described and be provided with the dust cover that blocks the positioning bolt head.
Compared with prior art, the beneficial effects of the utility model are: can the requirement to security classification according to the user, 1 ~ 10 group of multistage password is set, security classification is higher,, steal oily person and be difficult for finding in the device side due to the position of opening password, can make lock body avoid by the erosion of sleet, dust storm in natural environment simultaneously, safety is anticorrosion, and encryption lock can be remained valid for a long time.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment opening structural representation;
Fig. 2 is the utility model embodiment locking states structural representation.
In figure: the 1-base 2-upper cover 3-snap 4-snap ring 5-setscrew nut 6-positioning bolt 7-dust cover 8-10-lock ring one 11-lock ring two 12-groove 13-centring ring 14-fluting of unblanking that turns edge that turns edge outward in 9-
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
As Fig. 1, Fig. 2, it is the locked well device of a kind of encryption function of the utility model example structure schematic diagram, this device comprises that encryption lock and well block up, wherein encryption lock comprises base 1, upper cover 2, snap 3, snap ring 4, setscrew nut 5 and positioning bolt 6, one end overcoat upper cover 2 of base 1, the other end of base 1 is provided with and the stifled screw thread be connected of well, be provided with snap 3 in upper cover 2, the heart section of snap 3 is provided with snap ring 4, snap 3 all links into an integrated entity with upper cover with snap ring 4, the afterbody of positioning bolt 6 runs through upper cover 2 successively, base 1, after snap 3, with snap ring 4, be connected, positioning bolt 6 is provided with setscrew nut 5, setscrew nut 5 is provided with lock ring 1 and lock ring 2 11, be provided with the groove 12 of unblanking between lock ring 1 and lock ring 2 11, during opening, lock ring 1 and lock ring 2 11 are over against fluting 14 places, press password setting value turn positioning bolt 6, the just in time centring ring 13 of corresponding base end of groove 12 makes to unblank, now rotary upper cover 2, the 9 relative changing of the relative positions turn edge in outer 8 relative base 4 upper ends that turn edge of the outer end of snap 3, upper cover 2 and base 1 can be broken away from.
Setscrew nut 5 and positioning bolt 6, as lock core, are distributed with 1 ~ 10 group on upper cover 2 circumference, and security classification can be selected arbitrarily.Under the prerequisite that guarantees security classification, in order to improve the convenience of operation, the lock core preferred amount is 3 ~ 5 groups.By the change in size pin design of each setscrew nut 5, when multiple cipher is set, the position of each setscrew nut is different, and only having all setscrew nuts 5 is all that while rotating to a certain ad-hoc location, coded lock just can be opened.
During locking states, the relative base 1 of upper cover 2 is threaded to locked position, turn positioning bolt 6, when the lock ring 1 on setscrew nut 5 or lock ring 2 11 stay in fluting 14 place on centring ring 13, this timer is lockable, the stranger is not in the situation that know password, and this device is difficult to be opened, thereby reaches purpose secret, insurance.
For fear of the utility model device, by dust storm, attacked, upper cover 2 is provided with the dust cover 7 that blocks positioning bolt 6 heads.
