The purpose of the utility model is as follows: aiming at the defects in the prior art, the utility model provides a quick locking device.

The technical scheme of the utility model is as follows:

the utility model provides a quick locking device, includes fixed plate, slide bar, briquetting, rotation connecting rod, movable connecting rod, third pin, the fixed plate inside be U type groove, the briquetting have two, two mobilizable symmetrical arrangement of briquetting are on the U type inslot wall of fixed plate, movable connecting rod have two, two movable connecting rod one ends are articulated with two briquetting one-to-ones respectively, the other end passes through the third pin and articulates with two rotation connecting rod one end one-to-ones respectively, two rotation connecting rod other ends articulate on U type inslot wall, U type inslot be provided with the arc wall of symmetry, the third pin set up the arc wall in, and can follow the arc wall and slide, the third pin can drive rotation connecting rod, movable connecting rod motion, the briquetting be the L type, with slide bar end appearance phase-match.

Further, two briquetting splice on the U type inslot wall of fixed plate through first pin, the briquetting can be rotatory around first pin.

Furthermore, one ends of the two movable connecting rods are correspondingly hinged with the two pressing blocks one by one through second pins.

Furthermore, the other ends of the two rotating connecting rods are hinged to the inner wall of the U-shaped groove through a fourth pin.

Further, the width of the U-shaped groove is consistent with the thickness of the end of the sliding rod.

Furthermore, one end of the sliding rod is of a quadrilateral structure, and the left side and the right side of the sliding rod are symmetrical right angles.

The utility model has the beneficial effects that: the utility model provides a quick locking device which can be used for positioning and locking 2 independent objects and is convenient in locking and dismounting processes.

Drawings

FIG. 1 is a schematic view of the unlocked state of the present invention;

fig. 2 is a schematic view of the locking state of the present invention.

Detailed Description

The technical solution is further described in detail below with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and 2, a fast locking device comprises a fixed plate 1, a sliding rod 2, two press blocks 3, a rotating connecting rod 4, a movable connecting rod 5 and a third pin 8, wherein a U-shaped groove is formed at the end of the fixed plate 1, the two press blocks 3 are arranged in the U-shaped groove of the fixed plate 1 in a movable and symmetrical manner, the two movable connecting rods 5 are arranged in the U-shaped groove, one end of each of the two movable connecting rods 5 is hinged with the two press blocks 3 one by one, the other end of each of the two movable connecting rods 4 is hinged with one end of each of the two rotating connecting rods 4 one by one through the third pin 8, the other ends of the two rotating connecting rods 4 are hinged in the U-shaped groove, symmetrical arc-shaped grooves are arranged in the U-shaped groove, the third pin 8 is arranged in the arc-shaped groove and can slide along the arc-shaped groove to drive the rotating connecting rod 4 and the movable connecting rod 5 to move, one end of the sliding rod 2 is of a quadrilateral structure, the left side and the right side are symmetrical right angles, and the pressing block 3 is L-shaped and matched with the end shape of the sliding rod 2.

Further, two briquetting 3 splice in the U type inslot of fixed plate 1 through first pin 6, briquetting 3 can be rotatory around

first pin

6, 5 one ends of two movable connecting rods articulate with two briquetting 3 one-to-one respectively through second pin 7, two rotate the 4 other ends of connecting rod and articulate in U type inslot through fourth pin 9, the width in U type groove is unanimous with 2 end thicknesses of slide bar, can guarantee that U type groove can hold slide bar 2 completely.

Further, through inserting slide bar 2 in the U type groove of fixed plate 1, after contacting briquetting 3, continue the upward movement and force briquetting 3 rotatory, the rotation of slider drives movable connecting rod 5 simultaneously and moves, and the another side of briquetting 3 is approaching slide bar 2, until pressing slide bar 2, and the inboard profile of briquetting 3 matches completely with the quadrangle appearance of slide bar 2 this moment, and movable connecting rod 5 and rotation connecting rod 4 are the straight line simultaneously, and perpendicular with the lower profile of briquetting 3, form self-locking structure. The sliding bar 2 will be locked to the fixed plate 1.
