Abstract
The invention relates to a novel theft-proof lock, which is particularly used in a work door of a cable fastening type detachable well head crude oil (gas) theft-proof box. The novel theft-proof lock includes a lock housing, an upper lock bolt, a gear, a lower lock bolt, a lower rack, a connection pin, a compression spring, a sheet-shaped key, and a triangular key; the rack is arranged on the upper lock bolt; a kidney-shaped hole is formed in the lower lock bolt; the connection pin is arranged on the lower rack; the lower lock bolt and the lower rack are movably connected by allowing the connection pin to pass through the kidney-shaped hole, and the compression spring is arranged between the lower lock bolt and the lower rack; a end section of a rotation shaft of the gear is triangular; the gear is engaged between an upper lock bolt rack and the lower rack, wherein the upper lock bolt rack and the lower rack are parallel to each other; the lock housing and the lower lock bolt are provided with sheet-shaped rectangular grooves respectively, wherein the sheet-shaped rectangular grooves are identical in shape and are inverse in direction, and when the central lines of the two grooves coincide, the sheet-shaped key can be completely inserted. The novel theft-proof lock is unique in design, is reasonable in structure, is high in strength, and is excellent in theft-proof performance.
Description
Technical field
The present invention relates to a kind of novel anti-burglar lock, particularly relate to a kind of mechanical anti-theft lock on well recovery mouth crude oil (gas) theft-proof box, belong to anti-thefting facility technical field.
Background technology
At present, the well head in the areas such as China Sichuan, long celebrating, mostly it is dispersed on unfrequented hillside or mountain top.Owing to these well heads lack effective anti-thefting facility, thus the parts of crude oil (gas) in well head and wellhead tree equipment are stolen by lawless person repeatly, this not only brings heavy losses to national resources, but also causes the heavy damage of wellhead tree equipment.To this end, oil recovery unit has to put into substantial amounts of man power and material implements round-the-clock patrol nurse.Nonetheless, crude oil (gas) and the stolen of equipment component still happen occasionally.
Summary of the invention
It is an object of the invention to provide a kind of novel anti-burglar lock, be particularly well suited for use on the cleaning door in a kind of button cable formula dismantled and assembled Wellhead crue oil (gas) theft-proof box.
Above-mentioned purpose is implemented by the following technical programs: it includes lock housing, upper locking bolt, gear, lower locking bolt, lower tooth bar, connecting pin, stage clip and sheet key, triangle key.Described upper locking bolt is provided with tooth bar;Described lower locking bolt is provided with mounting hole, lower tooth bar is provided with connecting pin, is flexibly connected through mounting hole by connecting pin, and is provided with stage clip between lower locking bolt with lower tooth bar;Rotary shaft one end section of described gear is polygon, preferably: rotary shaft one end section is triangle;Described gear is simultaneously engaged between the upper locking bolt tooth bar being parallel to each other and lower tooth bar;Described lock housing be respectively equipped with the lamellar rectangular channel that shape equidirectional is contrary on lower locking bolt, and when two grooves overlap time can be fully-inserted by sheet key.
The present invention has the advantages such as design is unique, rational in infrastructure, intensity is high, theftproof performance is superior.
Accompanying drawing explanation
Accompanying drawing 1 is location state diagram during locking of the present invention;
Accompanying drawing 2 opens location state diagram during lower locking bolt for the present invention;
Accompanying drawing 3 opens location state diagram when lower locking bolt and upper locking bolt for the present invention;
Accompanying drawing 4 is triangle key schematic diagram of the present invention;
Accompanying drawing 5 is sheet key schematic diagram of the present invention.
In accompanying drawing 1,2,3: 1 lock housing, locking bolt, 3 gears, 4 triangular keyhole, 5 times tooth bars, 6 stage clips, 7 times locking bolts, 8 times latch aperture rectangular channels, 9 lock housing open rectangular channel, 10 mounting holes, 11 connecting pins on 2.
Detailed description of the invention
As shown in Figure 1, during locking, spring force one end of stage clip 6 holds out against that lower locking bolt 7 moves to limit locked position of coupler to the left, the other end holds out against lower tooth bar 5 and moves right, and lower tooth bar 5 driven gear 3 rotates counterclockwise.On below upper locking bolt 2, be provided with tooth bar, thus when gear 3 rotates counterclockwise, upper locking bolt 2 move to locked position of coupler under the driving of gear 3 to the left, i.e. go up locking bolt 2 and position time lower locking bolt 7 is simultaneously in blocking as shown in Figure 1.When unblanking, triangle key as shown in Figure 4 is inserted in triangular keyhole 4 as shown in Figure 2, sheet key as shown in Figure 5 is inserted in lock housing open rectangular channel 9 as shown in Figure 2, and artificial rotary triangle shape key counterclockwise, make gear 3 rotate counterclockwise.Gear 3 drives upper locking bolt 2 to continue to left movement, and meanwhile gear 3 drives again lower tooth bar 5 to move right.Owing to being provided with connecting pin 11 at the left end of lower tooth bar 5, right-hand member at lower locking bolt 7 is provided with mounting hole 10, and connecting pin 11 is interspersed in mounting hole 10, the most instantly when tooth bar 5 moves right, lower tooth bar 5 drives lower locking bolt 7 to move right by connecting pin 11, and its limit of sports record is that the centrage of lock housing open rectangular channel 9 only overlaps with the centrage of lower latch aperture rectangular channel 8.So far, lower locking bolt 7 is in unlocking condition and sheet key as shown in Figure 5, can be fully inserted to after lock housing open rectangular channel 9 overlaps with lower latch aperture rectangular channel 8 in the rectangular opening of the complete tetragon of formation, thus make lower locking bolt 7 can not make the transverse movement relative to lock housing 1.The position during unlocking condition that the blocking that on it, locking bolt 2 is in is in lower locking bolt 7 is as shown in Figure 2.Turn clockwise triangle key as shown in Figure 4, makes gear 3 rotate clockwise, and gear 3 drives upper locking bolt 2 to move right to unlocking condition;Gear 3 drives lower tooth bar 5 to left movement after the spring force overcoming stage clip 6, makes the connecting pin 11 of lower tooth bar 5 left end move in the mounting hole 10 of lower locking bolt 7 right-hand member simultaneously.Position when locking bolt 2 and lower locking bolt 7 are in unlocking condition on it is as shown in Figure 3.Unpluging triangle key as shown in Figure 4, sheet key as shown in Figure 5, lower locking bolt 7, upper locking bolt 2 are returned to locked position of coupler as shown in Figure 1.
