Description

Engineering machinery new door lock

Technical field

This utility model belongs to a kind of Engineering Machinery Components, specifically, particularly relates to a kind of engineering machinery new door lock.

Background technology

Engineering machinery hood side door lock has multiple at present, and major part all uses the big external lock of specialty, and price comparison is expensive, and accounts for Big with space, affect the attractive in appearance of overall appearance；Use the lock of small volume, the most solid, lack guiding and limit Position, the most often occurs locking unstable phenomenon.At present, also do not have one more satisfied in engineering machinery field The door lock of demand.

Utility model content

Attractive in appearance in order to overcome the door lock of hood in prior art to be positioned at side door external action, and big the lock higher and little lock of price is not Enough firm defects, this utility model provides one only lock core end and exposes, and with the guiding matched with latch hook and spacing, suitable Answer the outward appearance of hood wicket and use the engineering machinery new door lock required.

This utility model is achieved through the following technical solutions: a kind of engineering machinery new door lock, including base plate, and described base plate On be fixed with guide plate, lock core, described lock core is fixed with top board, the upwardly extending side of guide plate be provided with latch hook, turn Axle, torsion spring, described latch hook and torsion spring are fixed on guide plate by rotating shaft, and described one end hangs over outside latch hook, the other end Hang over and fix with guide plate on the torsion spring backing pin being connected, described latch hook is fixed with circular pin.

Described base plate is "Ji" type.

Described top board is rhombus.

Described guide plate top has groove that is spacing and that guide.

Separated by pad between described latch hook and guide plate.

Compared with prior art, the beneficial effects of the utility model are: this utility model fore shaft is less, does not affects the appearance so that The overall appearance of hood is the most attractive in appearance, and lock internal structure amesiality take up room little, reasonable in design, fastness Can be good.

Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings:

As shown in Figure 1 and Figure 2, a kind of dredger door lock, including "Ji" type base plate 1, with four rivets on base plate 1 9 are provided with " L " shape guide plate 2, and guide plate 2 top is provided with lock core 6, and lock core 6 penetrates guide plate 2 and base plate 1 by screw Rear fixing, lock core 6 can slide anteroposterior, lock core 6 top is fixed with the top board 7 of a rhombus by screw, and top board 7 is taked Anti-rotation measure, guide plate 2 top have spacing and guide groove, the upwardly extending side of guide plate 2 be provided with latch hook 5, Rotating shaft 3 and torsion spring 4, connected by rotating shaft 3 between latch hook 5, torsion spring 4 and guide plate 2, uses between latch hook 5 and guide plate 2 Pad separates, and torsion spring 4 one end hangs over outside latch hook 5, and the other end hangs on the torsion spring backing pin 10 being connected fixing with guide plate 2； Circular pin 8 it is welded with on latch hook 5.

Utility model works process: when lock core 6 drives top board 7 to move, top board 7 promotes circular pin 8 on latch hook 5, produces Raw gapless is moved continuously, has torsion spring 4 to connect between latch hook 5 and base plate 1, and torsion spring 4 rotates with latch hook 5 and reset latch hook 5。
