Description

A kind of dense block

Technical field

The utility model relates to a kind of locking device, is specifically related to a kind of dense block being applicable on large pressurized vessel door.

Background technique

Large pressurized vessel needs to install the seal container door with sealing function because having pressure difference inside and outside it, to guarantee that container door is under the state of locking, container is in sealing state, this just requires the locking device being equipped with on sealed door under the state of container door locking, should possess the function of sealing.Practical seal of vessel structure is mostly flange in the market, O-ring seal is joined locking nut form or linking rod structure form, these structure operations are loaded down with trivial details, and the structure of locking device or very heavy, and the processing request of unheavy locking device is high, is difficult for realizing.

Summary of the invention

For solving in prior art for locking device structure complexity on large pressurized vessel door, complex operation, processing request high-technology problem, the invention provides the easily dense block of realization of a kind of simple in structure, processing ease, processes.

, comprising dead bolt, drive block, fixed base, described dead bolt is arranged on drive block, and fixed base is shell construction, is fixed on seal container door; On the right flank inner housing of fixed base, guide rod is installed; Drive block right flank is processed with pilot hole, and pilot hole and guide rod match, and drive block can be slided in the hull shape of fixed base, it is characterized in that: drive block bottom surface is designed with dynamic trough; On fixed base, be processed with through hole, at fixed base through hole, the sleeve extending outside container door be installed outward; Running shaft is through the through hole of sleeve and fixed base, and the end of running shaft fixedly mounts eccentric disc, and eccentric disc is arranged in dynamic trough; Another end mounting handle of running shaft.

The ingenious utilization handle of the utility model driven rotary axle and eccentric disc rotate power are provided, and make drive block and dead bolt realize side-to-side movement, when dead bolt moves the dynamic resistance of locking piece, can realize the unlatching of container door.Adopt the structure of sleeve and running shaft, make the sealing effect of sealing lock better, simple in structure, processes easily realizes.

embodiment:

Below in conjunction with accompanying drawing, the utility model is further described:

, comprising dead bolt 3, drive block 2, fixed base 10, described dead bolt 3 is arranged on drive block 2, and fixed base 10 is shell construction and is fixed on seal container door 15; On the right flank inner housing of fixed base 10, guide rod 9 is installed; Drive block 2 right flanks are processed with pilot hole, and pilot hole and guide rod 9 match, and drive block 2 can be slided along guide rod 9 in the hull shape of fixed base, it is characterized in that: drive block bottom surface is designed with dynamic trough; On fixed base 10, be processed with through hole, at fixed base 10 through holes, the sleeve 12 extending outside container door be installed outward; Running shaft 11 is through the through hole of sleeve 12 and fixed base 10, and the end of running shaft 11 fixedly mounts eccentric disc, and eccentric disc is arranged in dynamic trough; Another end mounting handle 14 of running shaft.

Locking piece 1 is fixed on container box 16, during dense block locking, locking piece 1 is between dead bolt and container door 15, dead bolt 3 is stuck on locking piece, when needs dense block is opened from being latched to, dead bolt need move right, exit the engaging position with locking piece, pull handle, can realize the unlatching of container door, handle with sleeve 14, driven rotary axle 11 and the eccentric disc being fixed on running shaft 11 turn right, the dynamic trough of eccentric disc extruding drive block 2, dynamic trough is moved to the right along guide rod 9 directions with drive block 2, and the dead bolt being arranged on drive block 2 also moves right thereupon, exit the engagement with locking piece 1, container door 15 is opened.And dense block is from being opened to locking states when conversion, only need rotatable handle to the right, dead bolt is moved right, then promote container door, make dead bolt 3 cross locking piece 1, then rotatable handle 14 left, makes dead bolt 3 to left movement, realizes the engagement of dead bolt 3 and locking piece 1.

Technique scheme only can realize in the outside of container door locking and the open operation of container door, and for making container door also can realize the operation to dense block in inside, dense block of the present utility model also comprises guide wheel 6, screw rod 5; Screw rod 5 one end connect guide wheel 6, and the other end connects limiting stopper; Dead bolt 3 afterbodys are designed with breach, after dead bolt 3 is arranged on drive block 2, between dead bolt 3 and drive block 2 because dead bolt breach forms spacing space; Drive block 2 upper surfaces are designed with restraining groove, and restraining groove is located in spacing space, and under restraining groove, groove size matches with the size of limiting stopper, and the diameter width of upper well width and screw rod 5 matches; Limiting stopper is placed in the lower groove of restraining groove, and the screw rod 5 that connects guide wheel 6 sees through dead bolt 3 tail ends and is connected with the limiting stopper being limited in restraining groove.Pull guide wheel 6 to make its side-to-side movement, screw rod 5 drive dead bolts and drive block 2, along guide rod 9 side-to-side movements in the housing of fixed base 10, can be realized engagement, the not conversion between engagement between dead bolt 3 and locking piece 1.

For making the sealability of dense block better, described running shaft 11 reinstalls in sleeve after seal ring 13 is installed on its excircle, the gas flow of barrier container door inside and outside.

For making dead bolt can automatically restore to locking states, first inserting spring 8 in the pilot hole of drive block 2, and then the pilot hole of drive block 2 is enclosed within on guide rod 9.

Dense block, as the lock class of special occasions, if can also strain seal container door 15 under the function of locking, can better guarantee the sealing of container, and the utility model increases the function of tension container door on the basis of said structure for this reason.Concrete structure is as follows: on described drive block 2, be designed with engaging lug, on engaging lug, be processed with mounting hole, dead bolt 3 bottoms are processed with the connecting groove matching with engaging lug, dead bolt is processed with fixed shaft hole, stationary axle 4 passes the mounting hole of dead bolt 3 by fixed shaft hole, make by stationary axle, to be connected between dead bolt 3 and drive block; In dead bolt 3 tail end place screw rod 5 mounting holes, be processed with internal thread, match with the outside thread of screw rod 5.Under locking states, screw handwheel, because of dead bolt and the engagement of locking piece, under the drive of stationary axle, container door squeezing container casing 16 under the pulling that screws power of guide wheel of dense block has been installed, thereby has been made seal container there is good sealing effect.

For ease of dismounting, described guide wheel 6 is fixedly mounted on screw rod 5 by acorn nut 7.

Protection scope of the present invention is not limited only to the disclosed technological scheme of specific embodiments part, and all running shafts that utilized drive eccentric disc rotation, and the technological scheme that makes dead bolt carry out the conversion of locking opening state all falls into protection domain of the present utility model.
