Description
Technical field
The utility model relates to a kind of locking device, in particular to a kind of locking device of engineering machinery belongs to engineering machinery skill
Art field.
Background technique
With the development of economy, comfort increasingly becomes the factor of engineering machinery buyer consideration.Prolonged operation,
Driving indoor air quality can be remarkably decreased, and certain special operation conditions or weather are also required to being taken a breath, divulged information in driver's cabin.
Conventional locking device can only make window be in closure or unlimited two states, not take into account the requirement of mechanically actuated and ventilation, ventilation.
Special locking device can make window be in multiple states, but it is at high price, maintainability is poor, requirement is high.Therefore, it is badly in need of a kind of property
Valence can make window be in the locking device of multiple states than high, to take into account the requirement of mechanically actuated and ventilation, ventilation.
Summary of the invention
The utility model is to be intended to provide a kind of structure letter to overcome above-mentioned disadvantage of the existing technology to propose
Locking device single, easy to make, convenient for operation.
Technical solution: a kind of locking device of engineering machinery, including support, connector and locking bolt；The support, which is assemblied in, to be driven
Sail room column；The locking bolt is assemblied in side window；Coupled between the support and locking bolt by the connector；The support includes
Hinge pin；The connector includes connection ontology, closure fore shaft and unlimited fore shaft；The connection ontology and the hinge pin hole axle
Cooperation；The closure fore shaft is set to described connect the two ends of the body with unlimited fore shaft；In use, the connector is with the hinge pin
Centered on rotate clockwise, the unlimited fore shaft engages with the locking bolt, and the side window is in opening-wide state；The another connector
It is rotated counterclockwise centered on the hinge pin, the closure fore shaft engages with the locking bolt, and the side window is in closed state.
When the closure fore shaft and unlimited fore shaft neither fasten with the locking bolt, the side window is in big open state.
Preference reduces the shaking amplitude of connector for the reliability for guaranteeing side window closed state.The support further includes
Pilot pin, the pilot pin are set to below the hinge pin；The connector further includes kidney-shaped location hole；The side window is in and closes
When conjunction state, the location hole and the pilot pin are hole axle cooperation.
Preference engages for convenience of fore shaft is closed with locking bolt, prevents falling off for unlimited fore shaft and locking bolt.The closure fore shaft
Cross section is concave character type；The unlimited fore shaft cross section is Z-shaped.
Preference reduces driver's tool quantity for the purposes for improving connector.The connector further includes driving hole, institute
Stating driving hole is hexagon.
The utility model has the advantages that the utility model structure is simple, high reliablity is easy to maintain, and the use for being able to satisfy different operating conditions needs
It asks.
Detailed description of the invention
Fig. 1 is one structural schematic diagram of the utility model state；
Fig. 2 is the utility model transition state structural schematic diagram；
Fig. 3 is two structural schematic diagram of the utility model state；
Fig. 4 is the utility model confined explosion schematic diagram.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
As shown in figure IV, a kind of locking device of engineering machinery, including support 1, connector 2 and locking bolt 3；The support 1 fills
Assigned in room column 4；The locking bolt 3 is assemblied in side window 5；Coupled between the support 1 and locking bolt 3 by the connector 2.
The support 1 includes hinge pin 11 and pilot pin 12.The connector 2 includes connection ontology 21, closure fore shaft 22, opens wide fore shaft
23, location hole 24 and driving hole 25.The connection ontology 21 cooperates with 11 hole axle of hinge pin, the closure fore shaft 22 with open
Unlocking port 23 is set to 21 both ends of connection ontology.The pilot pin 12 is set to 11 lower section of hinge pin.
The utility model locking device can make side window 5 be respectively at three states, i.e., closed state, opening-wide state and open shape greatly
State, wherein opening-wide state main function is to drive indoor ventilation, ventilation.As shown in figure I, the side window 5 is in closed state,
Location hole 24 and pilot pin 12 are that hole axle cooperates, and can effectively avoid closure fore shaft 22 from falling off locking bolt 3, while reduction is because of connector 2
Vibration and the noise that generates.If side window 5 from closed state to opening-wide state, needs connector 2 is axial along pilot pin 12
Side be pulled outwardly, location hole 24 be detached from pilot pin 12, as shown in figure II, then by connector 2 with the hinge pin 11 be center up time
Needle rotation, while side window 5 is pushed, the unlimited fore shaft 23 engages with the locking bolt 3, and side window 5 is in opening-wide state, such as III institute of figure
Show.23 cross section of unlimited fore shaft is Z-shaped, then unlimited fore shaft 23 can be effectively ensured and do not depart from locking bolt 3.If side window 5 returns again
To closed state, then need centered on the hinge pin 11 to rotate connector 2 counterclockwise, while pulling side window 5, the closure
Fore shaft 23 engages with the locking bolt 3, and side window 5 is in closed state.Since 22 cross section of closure fore shaft is concave character type, connection
Part 2 can be moved along the hinge pin axial direction, but not depart from the hinge pin, and the location hole 24 is kidney slot, therefore
Location hole 24 is detached from pilot pin 12 and is easier to, so that switching of the side window 5 between closed state, opening-wide state is easier to, user
Just.When the closure fore shaft 22, unlimited fore shaft 23 neither fasten with the locking bolt 3, the side window 5 then opens shape in big
State.
For the demand for adapting to different type of machines and industrial and mineral, multiple unlimited fore shafts 23 can be equipped on connector 2, furthermore the spanner
Hole 25 is hexagon, matches with conventional fasteners shape, uses as spanner, can further improve the use of the utility model
Range.
Although be described in detail above to the utility model in conjunction with the embodiments, the technology people of the technical field
Member it is understood that without departing from the purpose of the present invention, can also above-described embodiment be changed or be changed,
Such as by the utility model use on door or hood, still fall within the protection scope of the present utility model.
