Abstract
The utility model discloses a limit locking device. The locking device comprises a limit seat (1), a limit bolt (2) and a handle (5). The limit bolt (2) is fixed on the inner side of the limit plate (1 - 2) on the top of the limit seat (1), and handle is hinged with the cantilever (1-1) of the limit seat (1) through the waist-shaped slot (5-1) on it. This limit locking device of this technology can achieve rotation and limit locking in promotion and demotion, and the utility model is simple in structure, low in cost and easy to apply. Through trial, the utility model works well.
Description
Technical field
The utility model relates to a kind of stopping means, relates in particular to a kind of spacing locking device.
Background technology
Often run in the life on the equipment of assemblings such as the spacing parts of frequent locking are applied to fold, rotation.And finish simultaneously rotation, spacing, locking relatively be difficult to the operation or the component structural complexity.Such as concrete mixing and transporting car, its input and output material system is the necessary parts of material concrete unloading, comprises discharge bucket, discharging chute, and discharging chute is installed in the discharging opening below, and can be in 180 degree scopes left rotation and right rotation.Need fix a position during discharging chute discharging, when discharging chute rotates, could realize by the manual push-and-pull of operator.The discharging chute oscilaltion also will could be regulated the lifting of discharging chute by the manually-operated elevating mechanism.This just requires the operator must finish simultaneously discharging chute rotation, lifting, three actions of spacing locking, and people of these actions is can't be unaided at one time, needs many people to finish complex operation, inefficiency.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of spacing locking device of finishing rotation, spacing locking action in Lift Part that can one man operation is provided.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is:
A kind of spacing locking device comprises limit base, spacer pin and handle, and described spacer pin is fixed in the limiting plate inboard of limit base top side, and described handle is hinged by its cantilever of going up the kidney slot of setting and limit base.
Described spacer pin is a bolt.
Between described spacer pin bolt and limiting plate, locking nut is set.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, this spacing locking device can be finished the action of rotation, spacing locking in lifting;
2, spacer pin is that bolt can be regulated spacing angle;
3, between spacer pin bolt and limiting plate, locking nut is set, can be better the fixing length of the protrusion of spacer pin bolt, make the spacing stable of spacing locking device;
4, simple in structure, with low cost and be easy to application.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in the figure, a kind of spacing locking device, comprise limit base 1, spacer pin 2 and handle 5, described spacer pin 2 is fixed in the limiting plate 1-2 inboard of limit base 1 top side, described handle 5 is hinged by its cantilever 1-1 that goes up the kidney slot 5-1 of setting and limit base 1, described spacer pin 2 is a bolt, between described spacer pin 2 and limiting plate 1-2 locking nut 3 is set.
Operation principle: as shown in the figure the dotted line state of handle 5 for rely on handle 5 or be fixed in handle 5 parts gravity in the raw, lifting handle 5 or be fixed in the parts of handle in the time of rotary handle 5, the gravity that relies on handle 5 or be fixed in the parts of handle 5 lock onto spacer pin 2, in actual applications can be by regulating height that length joystick 5 that spacer pin 2 protrudes promotes and spacing angle.Locking nut 3 can be better the fixing size protruded of spacer pin 2.
Claims (3)
1. spacing locking device, it is characterized in that: described locking device comprises limit base (1), spacer pin (2) and handle (5), described spacer pin (2) is fixed in limiting plate (1-2) inboard of limit base (1) top side, and described handle is hinged with the cantilever (1-1) of limit base (1) by the kidney slot (5-1) that is provided with on it.
2. spacing locking device according to claim 1 is characterized in that: described spacer pin (2) is a bolt.
