Abstract

The invention discloses a mechanical bullet locking mechanism, comprising an installation seat (3), a locking hook (1), a base body (13), a locking piece (4), a push rod (5), a spring sleeve (6), a handle (11) and a connecting rod (12). An arc-shaped groove is arranged in the axial direction of the installation seat (3); the locking hook (1) is arranged in a rectangular groove of the installation seat (3); and the locking hook (1) is connected with a pin roll (2) of an installation trunnion of the installation seat (3). During working of the mechanical bullet locking mechanism, the handle (11) drives the locking piece (4) to move along a sliding groove of the installation seat (3), the locking hook (1) realizes the switch between unlocking and locking states by barrel bullets and self-gravity, and the barrel bullets are fixed by pulling the push rod (5) by virtue of a compressed spring (7). The bullet locking mechanism has the advantages of no installation power source, simple manual operation, reliable barrel bullet lock and small installation room.

Description

A kind of mechanical lock bullet mechanism

Technical field

The present invention relates to a kind of lock bullet mechanism, particularly a kind of mechanical lock bullet mechanism.

Background technology

Present lock bullet mechanism comprises: drive oil sources, locked cylinder, lock hook, guide rail, mount pad and matrix; During work the tube bullet is filled in the guide rail, makes tube play leg and in the guide rail draw-in groove, slide, after lifting puts in place, tube is played the leg locking, thereby realize the fixing of tube bullet through locked cylinder.Comprise locked cylinder because lock plays in the mechanism, lock plays mechanism's installing space and becomes big, and unfailing performance descends.

Summary of the invention

The object of the present invention is to provide a kind of mechanical lock bullet mechanism, having solved present lock bullet mechanism also needs the big and not high problem of reliability of installing drive oil sources, locked cylinder installing space.

A kind of mechanical lock bullet mechanism, comprising: mount pad, lock hook, matrix also comprise: bearing pin, lock dog, push rod, spring housing, stage clip, sprue, baffle plate, connecting axle, handle, connecting rod.

Mount pad places on the matrix, and fixes with the matrix screw.There is the installation gudgeon both sides of mount pad, and installing on the gudgeon has through hole, mount pad arc groove axially arranged, rectangular recess is arranged at the top of mount pad, the sliding tray of lateral direction penetrating is arranged at the mount pad bottom.Lock hook places the rectangular recess of mount pad, and through hole is arranged at the lock hook bottom, and lock hook is connected with the mounting ear pivot pin axle of mount pad.Spring housing places the sliding tray of mount pad bottom, and fit in spring housing and mount pad bottom surface and screw is fixed.Sprue places the blind end of spring housing, and there is tapped through hole in the axle center of sprue, and stage clip places spring housing, and closely contacts with sprue.Push rod places stage clip, and an end and the sprue screw thread of push rod are fixed.Lock dog places the sliding tray of mount pad, and fits with the arc surface of lock hook, on lock dog and the side that mount pad contacts blind hole is arranged; Baffle plate places lock dog one end; And fix with the lock dog screw, the end that push rod has a taper surface places the blind hole of lock dog, and fits with the bellmouth of baffle plate.The lock dog afterbody has gudgeon, and all there is through hole at the connecting rod two ends, and connecting axle places the through hole of connecting rod one end, and connecting rod and lock dog are hinged.Handle is connected with the other end bolt of connecting rod.

When tube plays release; The bolt of handle along connecting rod clockwise rotated; Move axially through the sliding tray of connecting rod drive lock dog along mount pad, when lock dog moved to the arc surface of lock hook, lock dog no longer provided support lock hook; Lock hook turns clockwise around bearing pin under the effect of gravity, is fitted on the mount pad until arc surface.Lock dog to the pulling lock dog, fits tightly the arc surface of lock dog and lock hook through push rod shaft under the effect of stage clip, has realized the releasing process of tube bullet.During the locking of tube bullet, fit in the interior inclined-plane of tube bullet and lock hook, under the gravity effect of tube bullet; Lock hook is rotated counterclockwise around bearing pin, and passes torque to lock dog, and lock dog is moved axially along the sliding tray of mount pad; When the tube bullet is locked hook lock regularly fully, the moment that lock hook is added on the lock dog disappears, under the effect of stage clip; Push rod pulling lock dog moves forward along the mount pad sliding tray, until fitting with the lock hook intimate, realizes the locking of tube bullet.

Lock bullet of the present invention mechanism does not have the power source of installation, manual operation is simple, locking tube bullet is reliable, and installing space is less.
