Description

A kind of disposable safe lockset

Technical field

The invention belongs to the locking device of container counter safety precaution, be specifically related to a kind of one-time lock.

Background technology

The employed one-time lock of container counter on the domestic market, its structure is that ring spring is loaded onto in lock tube inside, it is exactly jump ring, locking bar is inserted in lock tube, until jump ring or ring spring are buckled in the draw-in groove of locking bar, and can not again oppositely pull out, thereby the clasp of groupage container door is locked, reach sealed purpose.But this structure exists following problem: at first, jump ring mostly is a contact or line contact with contacting of jump-ring slot, and this just makes the lifting surface area of jump ring and jump-ring slot less, and engagement force between the two is also just less, thereby easily destroyed, caused the safety factor of lockset lower; Secondly, fashionable to the lock tube interpolation at locking bar in use, the locking bar top props up on the steel wire of jump ring or ring spring sometimes, causes to be pressed into difficulty even can't to use use inconvenience.

Summary of the invention

Main purpose of the present invention provides the high disposable safe lockset of a kind of safety factor.

For achieving the above object, the technical solution adopted in the present invention is: a kind of disposable safe lockset, comprise lock tube and locking bar, lock tube comprises the lock tube housing, be provided with vertically bellmouth in the lock tube housing, bellmouth inside is provided with the pellet seat, the outer wall of pellet seat is taper, the tapering of pellet seat outer wall and the tapering of bellmouth coincide, pellet seat inside is provided with through hole vertically, the small-bore end of through hole and bellmouth is postponed and has been consisted of the lockhole that inserts for locking bar, radially be provided with the bullet groove that runs through the pellet seat on the through hole hole wall, be provided with pellet in the bullet groove, the bullet groove degree of depth and bullet groove are positioned at port size on the through hole hole wall of pellet seat all less than the diameter of pellet, and bellmouth is located on or near the large aperture end and sets firmly postive stop baffle, be provided with the reposition element that is connected both between pellet seat and postive stop baffle, locking bar comprises the body of rod and the pole cap that is positioned at body of rod tail end, and lever front end is provided with draw-in groove, and the pellet in the bullet groove consists of clamping with the draw-in groove of lever front end and cooperates.

Beneficial effect of the present invention is: after adopting said structure, during locking since pellet and draw-in groove cooperate be face contact and pellet between evenly distribution, stress balance, intensity is good and increased the area of the stressed junction of locking bar and lock tube, make the engagement force of locking bar and lock tube larger, increased the safety factor of lockset, the sliding friction that becomes simultaneously original when engagement is rolling friction of the present invention, and is more sensitive easy in the operation of carrying out when sealed.

The specific embodiment

As shown in Figure 1, a kind of disposable safe lockset, comprise lock tube and locking bar, lock tube comprises lock tube housing 10, be provided with vertically bellmouth 11 in the lock tube housing 10, bellmouth 11 inside are provided with pellet seat 50, the outer wall of pellet seat 50 is taper, the tapering of pellet seat 50 outer walls and the tapering of bellmouth 11 coincide, pellet seat 50 inside are provided with through hole 52 vertically, through hole 52 is postponed with the small-bore end of bellmouth 11 and has been consisted of the lockhole that inserts for locking bar, radially be provided with the bullet groove 51 that runs through pellet seat 50 on through hole 52 hole walls, be provided with pellet 20 in the bullet groove 51, bullet groove 51 degree of depth and bullet groove 51 are positioned at aperture 511 sizes on through hole 52 hole walls of pellet seat 50 all less than the diameter of pellet 20, bellmouth 11 is located on or near the large aperture end and sets firmly postive stop baffle 30, pellet seat 50 is provided with the reposition element 40 that is connected both with 30 of postive stop baffles, here said reposition element 40 can be electric power or magnetic force resetting, other resetting-mechanisms that elastic reset maybe can make pellet seat 50 reset, locking bar comprises the body of rod 70 and is positioned at the pole cap 80 of the body of rod 70 tail ends, the body of rod 70 front ends are provided with draw-in groove 71, and the pellet 20 in the bullet groove 51 consists of clamping with the draw-in groove of the body of rod 12 front ends 71 and cooperates.

The selected reposition element 40 of the present invention is the truncated cone spiral compression spring, is described preferred plan, and truncated cone spiral compression spring small end is resisted against the large end of pellet seat 50, and the large end of truncated cone spiral compression spring is against postive stop baffle 30.

For making lockset reach best safe effect, the small end of the bellmouth 11 in the lock tube housing 10 to the opposite side end face of lock tube housing 10 is provided with necking down hole 12, the aperture in necking down hole 12 is less than the small end aperture of bellmouth 11 and more than or equal to the aperture of pellet seat 50 inner via holes 52, and pellet seat 50 small ends are resisted against on necking down hole 12 and the shaft shoulder that bellmouth 11 small ends become.

Pellet 20 is at least 3 and circumferentially uniform along pellet seat 50, makes its stress balance.

Further, consider that assembling needs, bullet groove 51 is oblique layout, and the taper direction of its gradient direction and pellet seat 50 coincide, and pellet 20 just is difficult for dropping when assembling like this.

The aperture 511 of bullet groove 51 is the reducing shape, bullet groove 51 is positioned at the spherical cavity that the slotted eye wall 512 at 511 places, aperture matches for the curved surface with pellet 20, this structure can make pellet 20 be installed in the bullet groove 51, and slotted eye wall 512 can be guaranteed that pellet 20 is in and appears state and be stuck in the draw-in groove 71 of the body of rod 70 front ends, and can not damage aperture 511, and can reliably pellet 20 be drawn and crouch in bullet groove 51.

Further, the body of rod 70 leading section rounding ofves make sealed operation easier, are convenient in other words the insertion of the body of rod 70.

Draw-in groove 71 all can satisfy necessary requirement in gap or the continuously setting of making progress in the week of the body of rod 70.Draw-in groove 71 preferably can coincide with the spherical of pellet 20, to increase the engagement force of matching part along semicircular in shape structure on the cross section of the axis of the body of rod 70.

For improving the safe shape of lockset, can increase by an anti-rotating function, concrete scheme is: locking bar postmedian and lock tube outside are plastic, the axially extending bore 60 that is positioned at its front end after lock tube is plastic designs for square structure, be set to the square structure that matches with through hole 60 at its plastic front end after locking bar is plastic, in case intermesh in the square position of locking bar and lock tube, just reached the purpose of lockset anti-rotation.
