Description

A kind of quick-locking mechanism

Technical field

The utility model belongs to mechanical interlocking field, and in particular to a kind of quick-locking mechanism.

Background technique

Usually exist as follows not with the prior art that " lead screw+lead screw pair " is the driving structure of mobile bolt in locking mechanism Foot: bolt, which has, is convenient for adjusted jag, and overall structure seems not compact, and sometimes because limited space without Just it installs or adjusts；Locking loosely, is not provided between the mounting base connecting with bolt and lock core and reasonably positions and prevent to insert Pin, which bears the structure of axial force, lock core and mounting base, is not allowed there may be positioning and causes bolt that cannot be inserted into lock core well Problem, if bolt is by axial force, may shift leads to locking loosely；Bolt be mostly single head insertion lock core structure, one Denier single head is broken or because other fortuitous events is removed out of lock core, loses locking effect, locks and protect unexpected ability not By force.

Utility model content

The utility model provides a kind of quick-locking mechanism, it is intended to overcome structure existing for retaining mechanism in the prior art Not compact, installation adjusts the deficiencies of inconvenient, locking is not loosely strong with protection unexpected ability.

The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of quick-locking mechanism comprising installation Seat and fast lock core, the front of the mounting base, which slidably connects fast locking plug and is fixedly connected with, limits the fast locking plug front and back The front limited block of sliding distance and rear limited block, the fast locking plug are equipped with screw hole and close institute for U-shaped forked and its closed end Front limited block is stated, the rear limited block is located in the opening of the fast locking plug and offers the cylinder for hexagon socket head cap screw thereon The cruciform groove that head end is caught in, the other end of the hexagon socket head cap screw are threadedly connected in the screw hole, the mounting base Rear side is equipped with the fixing groove for the fast lock core along the direction insertion perpendicular to the mounting base reverse side, the fixing groove reverse side one The top and the bottom of side are opposite to be set there are two the card slot that is caught in of hanging support ear for fast lock core two sides up and down, is opened on the fast lock core Equipped with the through-hole passed through for adjusting spanner one end, described adjusting spanner one end can be caught in the interior hexagonal spiral shell after passing through the through-hole Interior hexagonal regulating tank on the cylinder end surface of bolt, the upper and lower side of the fast lock core is respectively equipped with to be open for the fast locking plug The locking slot that end upper and lower sides are caught in.

Based on the above technical solution, the utility model can also do following improvement.

Further, the front limited block is to be threadedly connected in the mounting base and two spaced along the vertical direction Bolt.

Beneficial effect using above-mentioned further scheme is that front limited block is specially two bolts, and one side can rise To the position-limiting action to fast locking plug, on the other hand also can be used as fixation spiral shell mounting base being fixed in associated workpiece simultaneously Bolt reduces the use of bolt.

Further, the spanner that adjusts is caught in one end of the interior hexagonal regulating tank as hexa-prism end.

Beneficial effect using above-mentioned further scheme is that structure is simple, easy to adjust, adjusts spanner and is specifically as follows just In the L shape manually adjusted or linear convenient for cooperating with electric wrench.

Further, the upper and lower sides of the fast locking plug open end are that the narrow end of wedge-shaped long slab and the wedge-shaped long slab can block Enter the locking slot.

Further, the front upper and lower sides of the mounting base are correspondingly provided with protective plate, two protective plates side relative to each other Face is recessed sliding slot at the mounting base, and the fast locking plug upper and lower sides are equipped with correspondence at the mounting base and are caught in The sliding block of the sliding slot.

Beneficial effect using above-mentioned further scheme is the mobility for making fast locking plug only and having along the chute, guarantees it While function, it is avoided to fall from mounting base.

Further, the front of the fast lock core is additionally provided with the screw hole for connecting hitch bar.

Beneficial effect using above-mentioned further scheme is, convenient for fast lock core as connection connecing to hanging support object Head.

Compared with prior art, the beneficial effects of the utility model are:

By setting cross recess on rear limited block and with the use of hexagon socket head cap screw, enable the Quick bolt that U-shaped is forked It is enough to slidably reciprocate in mounting base, it is compact-sized, it is led in no traditional lead screw and lead screw pair fit structure there are lead screw jag What is caused installs when narrow space and adjusts inconvenient problem；Quick bolt is that there are two wedge shape length for forked its open end of event of U-shaped Plate can be caught in locking slot to lock, and locking effect is good, even if a wedge-shaped long slab fracture, another still ensures that locking；Fast lock Two hanging support ears are symmetrically set on core, and the fixing groove for supplying fast lock core to pass through is set in mounting base and fixing groove is set at mounting base reverse side For the card slot that two hanging support ears are caught in, when fast lock core is inserted into fixing groove and hanging support ear is caught in corresponding card slot completely, fast lock core On through hole center be aligned just with the cylindric end face center of hexagon socket head cap screw, then be inserted into and adjust spanner and hexagon socket head cap screw cylinder The interior hexagonal adjustment hole clamping of shape end face and rotate fast locking plug can be driven mobile be inserted into the locking slot of the fast lock core or Unlock is extracted from locking slot, is not needed deliberately to remove to be aligned and adjust fast lock core, be locked and unlocked easy to operate；Mount ear not only Have the function of making fast lock core through-hole and interior hexagonal adjustment hole automatic aligning, additionally it is possible to bear the downward pulling force that fast lock core is subject to Or active force along the longitudinal direction, Quick bolt stress is avoided as far as possible, can be guaranteed locking effect and be guaranteed that Quick bolt is longer Service life.
