Abstract
The invention discloses a locking device for petroleum equipment, which comprises a latch hook (1), a lock catch (2), a lock catch seat (4) and a bolt (5), wherein the bolt (5) is movably connected with the lock catch seat (4), one end of the lock catch (2) is movably connected with the bolt (5), and the lock catch seat (4) is provided with a groove; when the other one end of the lock catch (2) is fastened to the latch hook (1), the bolt (5) is arranged in the groove of the lock catch seat (4), and meanwhile, the upper planes of the bolt (5) and the lock catch (2) are lower than that of the lock catch seat (4). The invention has the advantages of simple structure and skillful design, and effectively avoids damage to the bolt, the lock catch and a lock pin of the trigger of petroleum equipment because the petroleum equipment collides with the triggers on windows or covers during transportation or utilization.
Description
Technical field
The invention belongs to the oil drilling and extracting equipment technical field, relate to a kind of locking device that is used for oil equipment specifically.
Background technology
Oil-well rig is owing to standard, safe and reliable requirement.Need window, the opening and closing of lid of all equipment a kind of convenience will be arranged, solid, durable product.Because drilling equipment carrying and install frequently, is covered and is pulled button and often receive shearing force and pressure window on the equipment.Simultaneously owing to pull window, the cover upper surface that the button protrusion is installed in oil equipment; Collide easily in carrying or the use and pull button; If collide and pull dead bolt, snap close and the lock pin smashed and cause their damage, repair very trouble as this special equipment of oil equipment.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively avoid being used for oil equipment and using or carrying, window, covered that dead bolt, snap close and the lock pin of pulling button are damaged and the unexpected locking device of opening that is used for oil equipment.
Technical scheme of the present invention is following:
A kind of locking device that is used for oil equipment comprises latch hook, snap close, snap close seat and dead bolt, and said dead bolt and said snap close seat flexibly connect, and said snap close one end and said dead bolt flexibly connect, and have groove on the said snap close seat; When the said snap close other end and said latch hook fastening, the groove that said dead bolt the is positioned at the snap close seat simultaneously last plane of said dead bolt and snap close is lower than the last plane of said snap close seat.
Said snap close seat front end is provided with lock pin, and said dead bolt flexibly connects through said lock pin and said snap close seat; The position of wherein said lock pin is lower than the last plane of said snap close seat.
Adopt said structure; Make the position of dead bolt, snap close and lock pin all low, so effectively avoided colliding in the oil equipment carrying or in using window than the last plane of snap close seat, pulling of covering buckle, cause to pull dead bolt, snap close and the lock pin smashed and cause their damage.
Said snap close seat front end has journal stirrup; Said lock pin is arranged on the said journal stirrup; Have snap close return groove on the snap close seat near said journal stirrup, when said snap close and said latch hook fastening, the end both sides that said snap close links to each other with dead bolt drop in the said snap close return groove.
Said dead bolt front end is an arc, and when said snap close and said latch hook fastening, said dead bolt falls into and forms the breach of being convenient to pry open said dead bolt between the groove surface of said snap close seat groove and dead bolt front end and snap close seat.
Said snap close seat is " T " shape.
Beneficial effect: the present invention is simple in structure, be skillfully constructed, can effectively avoid colliding in the oil equipment carrying or in using window, cover pull button, cause and pull dead bolt, snap close and the lock pin smashed and cause their damage.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of snap close seat;
Fig. 3 is the structural scheme of mechanism of latch hook.
The specific embodiment
Embodiment: like Fig. 1,2, shown in 3; A kind of locking device that is used for oil equipment comprises latch hook 1, snap close 2, snap close seat 4 and dead bolt 5, and said dead bolt 5 flexibly connects with said snap close seat 4; Said snap close 2 one ends and said dead bolt 5 flexibly connect, and have groove on the said snap close seat 4; When said snap close 2 other ends and 1 fastening of said latch hook, the groove that said dead bolt 5 the is positioned at snap close seat 4 simultaneously last plane of said dead bolt 5 and snap close 2 is lower than the last plane of said snap close seat 4.
Said snap close seat 4 front ends are provided with lock pin 3, and said dead bolt 5 flexibly connects through said lock pin 3 and said snap close seat 4; The position of wherein said lock pin 3 is lower than the last plane of said snap close seat 4.
Said snap close seat 4 is " T " shape; Front end has journal stirrup 4a; Said lock pin 3 is arranged on the said journal stirrup 4a; Have snap close return groove on the snap close seat 4 near said journal stirrup 4a, when said snap close 2 and said latch hook 1 fastening, the end both sides that said snap close 2 links to each other with dead bolt 5 drop in the said snap close return groove.
Said dead bolt 5 front ends are arc, and when said snap close 2 during with said latch hook 1 fastening, said dead bolt 5 falls into the breach that formation between the groove surface of said snap close seat 4 grooves and dead bolt 5 front ends and snap close seat 4 is convenient to pry open said dead bolt 5.
