Existing engine door lock is embedded door lock (as shown in Figure 1), and the monnolithic case of the door lock is circular apparatus, directly
Footpath draws bright 1 in 10cm and with a semicircular rotation, after pressing rotation drawing bright 1 and rotating 90 degree, with rotation drawing bright 1
The connected inner side of the other end can produce 4cm dead bolts 2, and dead bolt 2 mutually blocks now door lock with interior plate and barred up.Due to pressing, rotating pass
Lock needs certain strength, has time point inspection person to be closed the door after inspection terminates and empty calorie occurs or blocks some phenomenons, due to existing
Bad environments ground is uneven, vehicle shake occurs, swag phenomenon causes tongue to pitch, and is directed at door-plate and ceaselessly rolls and hits
Hit, cause the damage of door-plate and door lock.
Utility model content
For drawbacks described above present in prior art, the purpose of this utility model is to provide one kind and is used for engine housing
Flush door locking device, can strengthen taking on trackless the protection of truck engine, while reduce to forget to rock after closing the door and make
Damaged into Door and its lock, and reduce potential safety hazard in process of production.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of flush door locking device for engine housing, including housing, dead bolt, pulling buckle, connecting rod and retainingf key
Pin, one end of housing are provided with opening, and dead bolt is located at aperture position, and pulling buckle is in housing, after the one side and dead bolt of pulling buckle
End is connected, and the another side of pulling buckle is connected with one end of connecting rod, and the other end of housing is provided with through hole, and the other end of connecting rod is worn
If crossing the outside that through hole is located at the housing other end, fixed key pin is connected with the end vertical of the other end of connecting rod, in connecting rod
Also it is arranged with spring.
Described connecting rod has two, is respectively arranged on the both ends of the another side of pulling buckle, the through hole of the other end of housing
It is correspondingly provided with two.
Limited block is additionally provided with the medial surface of the other end of described housing.
Radial direction offers connection through hole on the end of two described connecting rod other ends, and fixed key pin is inserted respectively
If two connection through holes, make to be fixedly linked between two connecting rods.
The front end of described dead bolt sets and is of an inclined plane.
In above-mentioned technical scheme, the utility model provides a kind of embedded door lock for engine housing and filled
Put, also with some following beneficial effect：
1. the utility model improves the efficiency of the inner body of protection engine；
2. the utility model reduces the spoilage of door-plate and door lock；
3. the utility model improves the security at scene.

Fig. 2 is structural representation of the present utility model；
Fig. 3 is the sectional view of a-a in Fig. 2；
Fig. 4 is schematic perspective view of the present utility model；
Fig. 5 is use state figure of the present utility model.
Embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1 to Fig. 5, a kind of embedded door lock for engine housing provided by the utility model fills
Put, including housing 1, dead bolt 2, pulling buckle 3, connecting rod 4 and fixed key pin 5, one end of housing 1 are provided with opening, dead bolt 2 is located at opening
Position, dead bolt 2 can stretch out retraction activity in aperture position, and pulling buckle 3 is in housing 1, after the one side and dead bolt 2 of pulling buckle 3
End is fixedly linked, and connecting rod 4 is provided with two, respectively the both ends of the fixed another side for being connected in pulling buckle 3, the other end of housing 1
Provided with corresponding two through holes so that after the other end of connecting rod 4 is fed through through hole, located at the outside of the other end of housing 1, two
Radial direction offers connection through hole on the end of the other end of root connecting rod 4, and it is logical that fixed key pin 5 is inserted into two connections respectively
Hole, make to be fixedly linked between two connecting rods 4, spring 6 is also arranged with every connecting rod 4, spring 6 is located at pulling buckle 3 and shell
Body 1 is provided between connection through hole one end, and housing 1, which is provided with the medial surface of connection through hole one end, is additionally provided with limited block 7, then by dead bolt
2 front end sets and is of an inclined plane.
Housing 1 is arranged on the door-plate 99 of engine, the inclined-plane of the front end of dead bolt 2 is set towards doorframe direction, when needing to close
Men Shi, only door-plate need to gently be pushed or pulled on towards doorframe direction, after the inclined-plane of the front end of dead bolt 2 touches doorframe, dead bolt 2 is from trend housing
It is retracted in 1, after door-plate completely closes, because the spring 6 in connecting rod 4 resets, makes connecting rod 4 drive pulling buckle 3 to reset together,
So as to promote dead bolt 2 to be stretched out out of housing 1 again, dead bolt 2 is just stuck on the medial surface of doorframe, realize the pass of engine door-plate
Close.When needing to open door-plate, only need staff to pull fixed key pin 5, make in the locking shell 1 of dead bolt 2, if work people
Member's motive force is spent greatly, pulling buckle 3 directly can be abutted with limited block 7, limited block 7 can prevent pulling buckle 3 to be drawn out housing 1
Outside.
In summary, situation about door-plate being shut in time is forgotten if there is staff, truck work is taken in trackless
Middle rotation door-plate is directly locked using inertia energy in a flash, protects engine, and reduce site safety well
Hidden danger, reduce the spoilage of door lock.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as to restriction of the present utility model, as long as in spirit of the present utility model, to described above
Change, the modification of embodiment will all fall in Claims scope of the present utility model.
