Description
Technical field
The utility model belongs to mechanical fixing lockset, is specially a kind of for inhale fixing lock in fixing locomotive driving cabin door for chamber door when the chamber of locomotive driving cabin door is opened.
Background technology
In general; in present engineering truck; its driver's cabin normally adopts the cab structure of sealing; with to driver better to protect; simultaneously; can provide better working environment for driver; but the enclosed cabin of this engineering truck in the course of the work; need often car door is carried out open operation or car door need to be remained to the opening of being left unlocked or unlatched with handled easily; and the fixing lock of door leaf can be fixed on door leaf the fixed equipment of certain opening exactly, prevent that it from rocking so that accident is closed at the situation exit door such as blow.
The easiest door leaf fixing device is on floor or one side of ceiling, also or one side of door leaf hook-shaped Lock Part is installed, at corresponding another side, the endless member that can tangle hook-shaped Lock Part is installed simultaneously, hook and ring can be articulated in above-mentioned enable possition, the operation of must squatting down or stand on tiptoe when articulating and take of such fixator, cumbersome; Also have and use the door-inhale of mutual-inserting type after door is opened, door to be locked on gusset, if will open door, also need driver from driver's cabin out, hand is pinned lockable mechanism, flick back pullout (BPO), and this architecture quality as above a kind of door leaf fixing device is stable, it is also very inconvenient to operate.
Utility model content
The technical problem that the utility model solves is to provide in a kind of locomotive driving cabin door inhales fixing lock, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
In locomotive driving cabin door, inhale fixing lock, comprise lock body and snap close, wherein, described snap close is a U-shaped buckle structure, be fixed on the sidewall of locomotive driving cabin chamber door, and being installed on the driver's cabin of locomotive driving cabin, described lock body opens the door in the sidewall of driver's cabin of side, comprise that one is locked the interlock handle base of lock body folding with door-inhale lock and a control door-inhale of snap fit, on described interlock handle base, be provided with an interlock handle hinged with interlock handle base, and be also connected with a return spring between this interlock handle end and interlock handle base; Meanwhile, be also provided with an operating flexible shaft in lock body, this operating flexible shaft one end is connected with the root of interlock handle, and the locking-up end that the other end is locked with door-inhale is connected and controls its folding.
In the utility model, door-inhale in described lock body part lock and interlock handle base are fixed relatively fixing with holding position by fastening bolt.
In the utility model, stretch out from the empty cavity position sidewall of driver's cabin side plate the operating side of described interlock handle, so that driver can operate the folding of lock body in driver's cabin.
In the utility model, described operating flexible shaft preferably adopts the wire rope that Anti-pull-press intensity is outstanding.
Beneficial effect: the utility model meets Ergonomics design, if solved engineer in operation process, to open door just need people out, hand is pinned the drawback of lockable mechanism, simple and efficient to handle, simultaneously, its compact conformation, compatible degree is high, fixing compact, and reliability is high, can effectively solve conventional door fan fixed mechanism and hold flimsy problem, effectively reduce this series products maintenance cost after sale.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the preferred embodiment of inhaling fixing lock in the locomotive driving cabin door of Fig. 1, in the present embodiment, comprise lock body and snap close, wherein, snap close is fixed on the sidewall of locomotive driving cabin chamber door, and lock body is installed on the driver's cabin of locomotive driving cabin, opens the door in the side plate 7 of driver's cabin of side.
In the present embodiment, for preventing lock body displacement, in the cavity of side plate 7, be also provided with a fixing lock body installation cavity 6, door-inhale lock 2 and interlock handle base 4 are arranged on respectively the lower left corner and the upper right corner of lock body installation cavity 6, centre connects by operating flexible shaft 3, this operating flexible shaft 3 is that the wire rope of three strands screws and forms, one end is fixed on the locking-up end of door-inhale lock 2, the other end is connected to interlock handle 5 roots on interlock handle base 4, and stretch out in cavity one side of side plate 7 at interlock handle 5, make can arrive interlock handle 5 by direct control in driver's cabin, and be also provided with a return spring 1 between this interlock handle 5 and interlock handle base 4.
Based on above-mentioned feature, driver can just can easily be fixed and loosen driver's cabin chamber door under the condition without map function position under opening, opening and closing in the time of near side plate 7, door body is during near side plate 7, snap close is pull-in in door-inhale lock 2, thereby keep the relatively fixing of driver's cabin chamber door, prevent that it from rocking so that accident is closed at the situation exit door such as blow.And when need to close driver's cabin chamber door, by operations linkage handle 5, control operation flexible axle 3 connects the switch of door-inhale lock 2, after door unclamps, interlock handle 5 is by return spring 1 pulling force return, and driver can close driver's cabin chamber door in driver's cabin.
