Abstract
The invention relates to a latching mechanism, which belongs to the technical field of a concrete pump. A bracket is fixedly mounted on a frame body; a sliding groove is formed in a position of the upper edge of the bracket; a fixing groove is formed in the position of the right end side of the sliding groove; a pin shaft barrel is fixedly mounted on one side of the bracket; an inserting pin is arranged in the pin shaft barrel; a spring is arranged at the right end of the inserting pin; a handle passes through the sliding groove; the bottom of the handle is movably hinged with the bracket; a long groove hole is formed in the waistline part of the handle; and the right end part of the inserting pin is hinged in the long groove hole of the handle through a sliding pin shaft. The latching mechanism has the advantages of very simple structure and good manufacturability. Particularly, the latching mechanism has good reliability in latching.
Description
Technical field
The present invention relates to concrete pump, be specifically related to the lockable mechanism of concrete pump supporting leg, belong to the concrete pump technical field.
Background technology
Concrete pump is after finishing the work, supporting leg needs to regain, concrete pump is in the process of travelling, the supporting leg of regaining easily swings, and for this reason, existing concrete pump generally all arranges the lockable mechanism that prevents that supporting leg from swinging, although existing concrete pump supporting leg lockable mechanism is not quite similar, but, generally exist complex structure, anufacturability relatively poor, especially there is the relatively poor defective of reliability of locking.
Summary of the invention
The object of the invention is to: for the existing defects of lockable mechanism of existing concrete pump supporting leg, the invention provides a kind of lockable mechanism of novel solidifying native pump supporting leg, overcome the existing defects of lockable mechanism of existing solidifying native pump supporting leg.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of lockable mechanism, it comprises: oscillating support leg, latch, the bearing pin cylinder, handle, sliding pin, fuselage, support, spring, it is characterized in that: be mounted with support at fuselage, described support is U-shaped structure, position, described U-shaped support top is shaped with chute, right-hand member sidepiece at chute is shaped with hold down groove, be mounted with the bearing pin cylinder in U-shaped support one side, in the bearing pin cylinder, be provided with latch, described latch right-hand member stretches out the outside of latch cylinder, the right-hand member of latch be provided with spring, after handle passes chute, its bottom is hinged with support actively, waist position at handle is provided with long slot bore, and the right part of latch is hinged in the long slot bore of handle by slidiing pin.
Beneficial effect: the present invention is because after adopting said method, so, structure of the present invention in the extreme simple, anufacturability is better, the reliability that especially has a locking is advantage preferably.
