The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The engineering truck that illustrating the utility model embodiment the provides structure of car door lock.For convenience of explanation, only show the part relevant to the utility model

Referring to accompanying drawing, to the utility model embodiment engineering truck being described in further detail with car door lock.

As shown in Figure 1-Figure 3, the engineering truck of the utility model embodiment mainly is comprised of swing arm 1, the first snap close palm the 2, first screw rod 21, the second snap close palm the 3, second screw rod 31, the second return spring 4, the first return spring 5, handle 6, lock core 7, handle push-and-pull control stick 8 and T-shaped connecting rod 9 with car door lock; The handle pull bar is connected by rivet with swing arm, and the handle pull bar in the above also can be below or side.The handle pull bar also can be split up into two parts and connect by connecting rod.Swing arm 1 connects the first screw rod 21 and the second screw rod 31 by steel joint or pull bar, plastic button, the first screw rod 21, the second screw rod 31 and swing arm 1 add cottor pin, snap ring or nut by pad and add anti-skid washer and fix, the first return spring 5 and the second return spring 4 are set to torsion spring or extension spring, with T font connecting rod 9, with the second return spring 4, the first return spring 5, be connected, in the process that pushes away, draws, only have a spring-compressed to play reset role, in the process pushed away, No. two springs work, in the process of drawing, a spring works, thereby realizes two-way reset.Operating process of the present utility model is: the driver (operator) in engineering vehicle cab (operating room) is advancing, while going out driver's cabin, the first step, must first by lock core 7, lock be opened, second step, , by pull handle 6, door is opened, this completes by two steps, the engineering truck sliding door arrives back by the door slippage at the door lock of opening front later again, then by the door lock of back, door is fixed, car door is not just understood the front and back vibration, at the driver's cabin drawback lock, with two steps of opening the door, be disposable completing, the car door lock of engineering truck sliding door driver's cabin is by front, rear two locks and one group of operating mechanism composition, closed door is fixing with one of front lock, the car door slippage is fixing with one of back lock to back, the driver is narrow space in driver's cabin, driver's operation must be simple, convenient, flexibly, the utility model fully takes into account human oriented design, the driver only need touch with a have gentle hands as long as sit on the seat, handle push-and-pull control stick 8, thereby the first snap close that drives the first screw rod 21 and the second screw rod 31 drive door locks by swing arm 1 is slapped swinging up and down of the 2 and second snap close palm 3, before just realizing, rear two locks are opened, before both can having realized, after unblank, before realizing again, after, open, close the door, the driver is sitting in driver's cabin while needing to open car door, only swing arm 1 one need be drawn backward gently, swing arm 1 drives the first screw rod 21 and the second screw rod 31 breaks away from snap close, now, lock is opened, before opening, in lock, continue toward post-tensioning, sliding door slides backward and the door lock of locking back is fixed car door.But the driver needs at closing time after entering driver's cabin, the driver is sitting in driver's cabin as long as pull bar 1 one is pushed away to the lock of back this moment and opens gently forward, after opening, in lock, continue to push away forward, sliding door is fixed closing of the door toward front slide the door lock of locking front, the unlatching of door lock, locking and opening, close the door and simply push away by one exactly, pull bar 1 has moved, operate very simple, convenient, the first screw rod 21 and the second screw rod 31 and being connected of swing arm 1 are that steel joint can be also pull bar and the linking of plastic button, the mode that is connected and fixed of the first screw rod 21 and the second screw rod 31 and swing arm 1 is that to add cotter pin hole can be that snap ring or nut add anti-skid washer to pad, the first return spring 5 and the second return spring 4 can be also torsion spring or extension spring.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
