Background technology
For a long time, the locking of Bolt Connection or simple and easy hasp is adopted in the sealing of casing or cylindrical shell, locking mostly.The Bolt Connection form need be used special tool (as spanner, screwdriver etc.), realizes locking by swivel nut.The shortcoming of this locking mechanism is: the operating time is longer, the seal loading inequality, and sealing, the locking of the casing especially big, that locker is more to volume, its shortcoming is more outstanding.At present, the latching device of the simple and easy hasp form of market sale is characterized in: simple in structure, easy to process, but oad is bigger.When a plurality of casings up and down or about abut against a time-out, the sealing member between case mouth or the nozzle easily produces permanent deformation because of long-term overload, has shortened the service life of sealing member.How a kind of novel quick-locking device is provided, makes its locking and open convenient and swiftly, and can prevent the permanent deformation that sealing member produces because of long-term overload, this be to need the urgently technical matters of solution at present.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and provide a kind of case outspoken fast latching device, and can finish locking, sealing and unlatching between case mouth or the nozzle fast, can make casing be close to, be bound up, can prevent the sealing member overload in the case mouth again, prolong its service life.The further purpose of the utility model is the case mouth that the outspoken fast latching device of a kind of case of size goes for multiple different size.
The utility model is achieved by the following technical solution: the outspoken fast latching device of a kind of case, comprise snap close, following snap close, lock body, handle, it is characterized in that described lock body is a C shape, lock body one end and shaft-like handle front portion are hinged, the threaded locking depression bar in outside is set in the screw of lock body other end setting, described upward snap close and following snap close are Z-shaped and are symmetrical arranged, on the last snap close approach end relative strut bar and slot are set respectively with following snap close, the handle front end is middle hinged with following snap close, the handle middle part is provided with registration mast, end near the handle middle part on the following snap close keeps off tongue by the hinged arc of bearing pin, the torsion spring that the retaining tongue is rotated is set on the bearing pin, on the arc retaining tongue registration mast jack is set.
The described strut bar buckled of locking is a location set screw, is installed in the screw of snap close one end, lock buckle be provided with one with locate the vertical fixing screw of set screw, the fixing screw front end withstands on locatees on the set screw.
Described going up on snap close and following snap close and the casing joint face is provided with fixed screw holes.
Described C shape lock body is the osed top case in location set screw and locking depression bar upper section.
The utility model has many advantages and good effect compared with prior art:
1, the utility model can be finished locking, sealing and the unlatching between case mouth or the nozzle quickly and easily, and is simple to operate, lock sealing is reliable.When casing is subjected to different directions external force, limit relatively moving between upper and lower casing at three-dimensional, protection casing and sealing member are not damaged.
2, the locking depression bar and the location set screw that are provided with of the utility model is convenient to regulate, and makes a kind of outspoken fast latching device of case of size go for the case mouth of different size.
3, the utility model compact conformation is easy to make, is a kind of engineering goods that show unique characteristics, and is particularly suitable for the case mouth locking of large-size box, also can be used in the locking of nozzle or other similar structures, and is of many uses.
Description of drawings
Fig. 1 is the outspoken fast latching device local section constructional drawing of the utility model case;
Fig. 2 is that the A-A of Fig. 1 is to section-drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, the embodiment of the outspoken fast latching device of a kind of case, lock body 2 is a C shape, lock body 2 one ends and shaft-like handle 14 are anterior hinged by straight pin 16, and the threaded locking depression bar 4 in outside is set in the screw of lock body 2 other end settings.Last snap close 3 and following snap close 10 are Z-shaped and are symmetrical arranged, and on last snap close 3 and following snap close 10 and the casing joint face fixed screw holes 9 are set, and will go up the upper and lower that snap close 3 and following snap close 10 are fixed on box mouth respectively by check screw 1.On the relative approach end of last snap close 3 and following snap close 10 strut bar and slot 8 are set respectively, the strut bar of buckling of locking can be a location set screw 7, be installed in the screw of snap close 3 one ends, location set screw 7 front ends are round slip surface, the screwdriver slot is set on the aft end face, and a nut 18 is equipped with in set screw 7 rear ends, location.Be provided with on the last snap close 3 one with the vertical fixing screw 6 of location set screw 7, fixing screw 6 front ends withstand on the set screw 7 of location.Hinged in the middle of handle 14 front ends and the following snap close 10 by straight pin 17, handle 14 middle parts are provided with registration mast 15, end near handle 14 middle parts on the following snap close 10 keeps off tongues 13 by bearing pin 11 hinged arcs, the torsion spring 12 that retaining tongue 13 is clockwise rotated is set on the bearing pin 11, on the arc retaining tongue 13 the registration mast jack that can embed registration mast 15 is set.C shape lock body 2 is an osed top case 19 in location set screw 7 and locking depression bar 4 upper sections.
Working process of the present utility model is: upper and lower snap close 3,10 is respectively with being fixed on the upper and lower casing with deciding screw 1, with slot 5 places in the middle of the last snap close 3 of locking depression bar 4 front ends aligning, clockwise rotate handle 14, the registration mast 15 on the handle 14 embeds in the registration mast jack on the arcs retaining tongues 13.The effect of arc retaining tongue 13 is to guarantee that handle is in plumbness all the time, and reliable location, can not become flexible because of transportation, lifting.Size according to upper and lower case mouth, adjust the relative position of locking depression bar 4 and lock body 2, allow locking depression bar 4 front ends press closer in the slot 5 of last snap close 3 centres, after making its amount of compression that reaches design-calculated predetermincd tension and sealing member fixing, location set screw 7 is adjusted in rotation, makes location set screw 7 leading sections be tight against down snap-lock 8 places.Guarantee that seal loading is constant, avoid sealing member to lose efficacy, prolong the service life of sealing member because of overload produces permanent deformation.In addition, because upper and lower snap close 3,10 its special slot locate modes can overcome because case internal pressure and lifting transportation to the squeese pressure of casing, stop casing to produce phenomenons such as dislocation, distortion.
When opening casing, need the outspoken fast latching device of the case on the casing is opened one by one, as long as with pointing push and block tongue 13 forward, make retaining tongue 13 rotate counterclockwise certain angle, registration mast 15 on the handle 14 withdraws from from keeping off in the registration mast jack on the tongue 13, and it is that fulcrum rotates counterclockwise certain angle that handle 14 can wind with straight pin 17, and lock body 2 moves with handle 14, locking depression bar 4 on handle 14 front ends will withdraw from from slot 5, and the outspoken fast latching device of case just is unlocked.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
