Abstract
The utility model discloses a heavy bulb coupling gear locking structure for a vehicle, and the locking structure comprises a locking pressing plate, a bulb seat, a traction bulb, a flat washer and a beta-shaped elastic pin; and the bulb of the traction bulb is arranged in the inner cavity of the bulb seat to enable the bulb to freely move, the locking pressing plate is installed in a flat circular hole of a traction bar on the front part of the traction bulb, the locking pressing plate is arranged right above the bulb seat, and the locking pressing plate is locked through the flat washer and the beta-shaped elastic pin. The utility model provides a locking device having high reliability, good safety, simple structure and convenience in operation and used for preventing the accidental dropping of the bulb during the coupling process for coupling the bulbs of such mainframes as automobile and tractor, and the like, with heavy towed vehicles and machines, and the locking device improves the working efficiency and effectively guarantees the application safety of users.
Description
Technical field
The utility model belongs to vehicular field, relates to a kind of vehicle and uses hanging device, relates in particular to a kind of vehicle with heavy bulb hanging device locking mechanism.
Background technology
At present, China is engaged in the vehicle of over-the-road transportation operation, comprises power actuated vehicles such as automobile, trac., construction machinery and equipment, and articulating between its main frame and heavy-duty vehicle or the heavy facility often adopted the bulb hanging device, and this apparatus structure is simple, articulates conveniently.But in use the accidental phenomenon can occur, exist potential safety hazard.Therefore, a kind of locking mechanism of design on this bulb hanging device can prevent effectively that just this obscission from taking place, and will receive user's favor.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, vehicle that reliability is high, easy to operate with heavy bulb hanging device locking mechanism.
The utility model adopts following technical scheme to achieve the above object: vehicle comprises with heavy bulb hanging device locking mechanism: locking pressure plate, ball cap, traction bulb, flat gasket and β shape resilient pin; The bulb of traction bulb is placed the ball cap inner chamber, make it can be free movable, in the flat round hole of the procephalic draw bar of tow ball, locking pressure plate is housed, locking pressure plate places directly over the ball cap, and the locking keep plate is locked through flat gasket and β shape resilient pin.
The utility model adopts the beneficial effect after the technique scheme to be: provide a kind of reliability height, the bulb that prevents that safety is good, simple in structure, easy to operate to articulate the latching device of accidental for main frames such as automobile, trac. and the heavy bulb that is pulled between vehicle and the facility articulate; Improved work efficiency, ensured that effectively the user's is safe in utilization.
Description of drawings
Fig. 1 looks partial schematic sectional view for the utility model vehicle with the master of heavy bulb hanging device locking mechanism.
Fig. 2 is the plan structure scheme drawing of the utility model vehicle with heavy bulb hanging device locking mechanism.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Vehicle comprises with heavy bulb hanging device locking mechanism: locking pressure plate 1, ball cap 2, traction bulb 3, flat gasket 4 and β shape resilient pin 5; The bulb of traction bulb 3 is placed ball cap 2 inner chambers; Make it can be free movable; In the flat round hole of the draw bar that draws bulb 3 front portions, locking pressure plate 1 is housed, locking pressure plate 1 places directly over the ball cap 2, and locking keep plate 1 is locked through flat gasket 4 and β shape resilient pin 5.
When automobile, trac. or other construction machinery and equipment traction heavy-duty vehicle or heavy facility in motion process owing to jolt; When ball cap 2 will be deviate to draw bulb 3; Receive the barrier effect that is positioned at the locking pressure plate 1 directly over the ball cap 2; Be pulled ball cap 2 and just can not take off and draw bulb 3, prevented the accidental release of hanging device.In addition because the barrier effect of β shape resilient pin 5, prevented locking pressure plate 1 because motion is jolted up and down the accident that causes of play deviate from; Simultaneously, β shape resilient pin 5 makes β shape resilient pin 5 snap closes laterally to scurry out because of itself having the locking effect.Guarantee the effect of 1 pair of ball cap 2 accidental locking of locking pressure plate, reached the purpose that prevents bulb hanging device accidental.
Throw off when articulating when needs, at first take away β shape resilient pin 5, extract locking pressure plate 1 out, lift ball cap 2 and can accomplish separating of main frame and towing vehicle or facility.After the disengagement, again the bearing pin of locking pressure plate 1 is inserted in the elongated hole, load onto flat gasket 4 after, insert β shape resilient pin 5, prevent losing of locking pressure plate 1.
The utility model is that main frame such as automobile, trac. and the heavy bulb that is pulled between vehicle and the facility articulate and provide the bulb that prevents that a kind of reliability is high, safety is good, simple in structure, easy to operate to articulate the latching device of accidental; Not only make the user improve work efficiency, ensured effectively that simultaneously the user's is safe in utilization.
