Abstract
The utility model relates to a hydraulic lock assembly which consists of a key core base, a key core and an annunciator. The key core is arranged into the key core base through a snap spring and provided with a key hole. The key core and the key core base are axially provided with two groups of marble holes, with the front group of marble holes communicated with the key hole and used for containing a plurality of marbles and hydraulic pistons, and the back group of marble holes not communicated with the key hole and used for containing a plurality of springs, marbles and hydraulic pistons. An oil way which is communicated with the two groups of marble holes is arranged on the key core base and is sealed with a sealing element and a screw bolt which is provided with two annunciating triggering plates, when the oil way is injected with liquid oil. The two annunciating triggering plates are orderly connected with the power supply and the annunciator through a wire. The hydraulic lock assembly has a concealed hydraulic pressure fastening structure, has the functions of theft prevention, breaking prevention and annunciation, and is applicable for the locking of various doors such as the theft-proof door, etc.
Description
Technical field
The utility model relates to a kind of lock assembly, particularly have antitheft, the fluid pressure type lock assembly of pick-proof and warning function.
Background technology
The assembly of lock all adopts pellet shot from a slingshot now, the latch lock fixed structure, and the weak point of technical existence is that lock core marble all can touch from keyhole, pellet shot from a slingshot, spring are destroyed by the robber easily, and lose the function of lock.
Summary of the invention
Goal of the invention of the present utility model provides a kind of simple in structure, easily makes, and cost is low, and is antitheft, the fluid pressure type lock assembly of pick-proof dependable performance and tool warning function.
To achieve the above object of the invention, the technical solution adopted in the utility model is: the fluid pressure type lock assembly is made of lock core base, lock core and alarm, it is characterized in that described lock core is placed in the lock core base by jump ring; Just do not have and the orthogonal yi word pattern keyhole in pellet shot from a slingshot hole on the lower side at described lock core center; Described lock core and lock core base radially be respectively equipped with two groups of pellet shot from a slingshot holes, preceding group of pellet shot from a slingshot hole is connected with keyhole, group pellet shot from a slingshot hole, back is not communicated with keyhole, pellet shot from a slingshot, hydraulic pressure plug are laid in preceding group of pellet shot from a slingshot hole, the back is organized the pellet shot from a slingshot hole and is laid spring, pellet shot from a slingshot, hydraulic pressure plug; Described hydraulic pressure plug is made with colloidal materials (or other material), and tightness is good, and can move up and down in the pellet shot from a slingshot hole; Described spring has stronger elastic force, can promote hydraulic pressure plug, pellet shot from a slingshot return.The top, pellet shot from a slingshot hole of described lock core base is provided with an oil duct that communicates with two groups of pellet shot from a slingshot holes, and hydraulic oil is loaded in the oil duct, blocks up with seal and bolt; The front end of described bolt is provided with two warning contacts, contact is used lead and external power supply (dry cell) by bolt (electric insulation is adopted in the junction of contact and bolt), alarm connects in order, for guaranteeing that two contacts well contact, and not influencing electric conductivity, following contact top is provided with many needle-like contact.Top, described lock core base pellet shot from a slingshot hole (oil duct top) is blocked up with plug and is welded.The tail end of described lock core links to each other with lock body assembly push boat.
Erection procedure of the present utility model is: earlier the pellet shot from a slingshot with hydraulic pressure plug, lock core base is placed in the pellet shot from a slingshot hole of lock core base by lock core hole, will place spring again, and the lock core of pellet shot from a slingshot screws in the lock core base, with jump ring with the lock core respective fixation; Then key is inserted keyhole, lock core is threaded to opening, hydraulic oil is injected oil duct, at last with seal, bolt with oil duct junction stifled go up and be adjusted to make pellet shot from a slingshot, hydraulic pressure plug move down into terminal point (oil duct does not have the space), make two warning contacts be in the upper and lower position relatively simultaneously.
Operating principle of the present utility model is: when normal condition, under the acting force of the spring behind lock core in the group pellet shot from a slingshot hole, group pellet shot from a slingshot, hydraulic pressure move beyond the Great Wall after promoting, and group hydraulic pressure plug moves down before making by hydraulic oil, and two groups of pellets shot from a slingshot are in latched position before and after making; When unblanking, key is inserted keyhole, preceding group of pellet shot from a slingshot, hydraulic pressure move beyond the Great Wall, and the active force that overcomes spring by hydraulic oil promotion back group hydraulic pressure plug, pellet shot from a slingshot moves down, and two groups of pellets shot from a slingshot are in opening before and after making, and rotary locking cylinder can be finished and unblank, the action of locking.When if the robber prizes the utility model,, can not touch from keyhole because back group pellet shot from a slingshot is in stealthy state; Preceding group pellet shot from a slingshot adopts hydraulic principle, and is also survivable, even preceding group of pellet shot from a slingshot destroys, the back is organized pellet shot from a slingshot and still is in the lock state, thereby protects lock core to be prized effectively.Simultaneously, when non-lock key or foreign matter insertion keyhole, as long as there is a tooth mouth not coincide with original key, the hydraulic pressure plug touches the warning contact, connects alarm circuit, alarm work.When this lock key is lost or is changed key, unclamp the oil duct bolt, insert similar key, regulate bolt again, can reach the purpose of changing key.Owing to adopted technical scheme as above, the utility model compared with prior art has the following advantages: (1) lock core pick-proof performance is good; (2) key is difficult for preparation, and preceding group of pellet shot from a slingshot destroys, and back group pellet shot from a slingshot is in stealth, and lock core still can lock, not the function of losing lock; (3) key is changed conveniently; (4) simple in structure, cost is low, is applicable to the assembly of multiple lock; (5) warning performance is good.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Further describe the utility model below in conjunction with accompanying drawing.
