Description
Technical field
The utility model relates to a kind of lock, and particularly a kind of road surface is used for the lockset of asphalt pavement maintanance truck pitch hopper.
Background technology
At present, in the flexible pavement reinstatement works, repair speed and raise the efficiency in order to accelerate the road surface, is furnished with the pitch hopper that loads pitch on the existing pavement maintenance truck, the pitch hopper is constantly impacted in the vibration of jolting owing to vehicle in transportation of block pitch material, door lock on the pitch hopper is damaged easily, often cause the hopper door can not open or improper opening.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, cost of manufacture is low, sturdy and durable, the impact that can effectively carry the pitch material and the lockset that is used for asphalt pavement maintanance truck pitch hopper of not fragile and flexible operation, to overcome weak point of the prior art.
A kind of lockset that is used for asphalt pavement maintanance truck pitch hopper by this purpose design, comprise the latch of an end sleeve in snap close, its architectural feature is that latch is arranged in the pin bushing, be provided with spring between latch and the pin bushing, pin bushing joins with helping pull a cart, help pull a cart and handle joins, help pull a cart with pin bushing between be provided with corresponding rotation bonding surface.
Be provided with step through-hole in the described pin bushing, latch one end pass stretch into behind the step through-hole help pull a cart in, bearing pin links together latch with helping pull a cart, compression spring one end is resisted against on the step of latch head, the other end is crimped on the step of step through-hole, pin bushing and help pull a cart on be respectively arranged with first and rotate in conjunction with inclined-plane and second and rotate in conjunction with the inclined-plane.
Described first rotation is rotated in conjunction with inclined-plane and second and is provided with first locating surface and second locating surface respectively in conjunction with sloped roof portion.
Unexpected loosening in order to prevent, be respectively arranged with locator protrusions and locating slot on first locating surface and second locating surface.
The utility model mode of occupation is as follows: after hopper door pass puts in place, turning handle 180 degree, latch inserts under the effect of spring force and remains in the lockhole of snap close, hopper door and firm being fixed together of hopper body are in closed condition, vehicle block bituminous mixture in driving process produces when impacting casing, hopper door and lock and can not produce impact force to spring substantially, therefore pitch hopper lock can not be damaged, and has guaranteed normal use; When needs are opened chamber door, earlier handle is pulled out outward, after bolt axle breaks away from snap close, again handle is rotated 180 degree, make first locating surface of pin bushing and help pull a cart second decide face and dock, thereby overcome spring force and keep static stable state, the hopper door can freely be opened, and makes things convenient for the loading and unloading of bituminous mixture.
