The power transmission structure that the lug boss is elastically occluded with the concave teeth is adopted for a lower horizontal pipe of the U-shaped elbow, which is connected with the engineering truck, so that a rearview mirror on a vertical pipe section of the U-shaped elbow can rotate along the horizontal axis, the rearview mirror adjustment requirements of different drivers for different vision fields can be met, the rearview mirror is free from vision blind area, and the safety in driving can be guaranteed.
Description
Technical field
The present invention relates to a kind of driving mirror bracket, is a kind of for engineering truck specifically, has the driving mirror bracket of the rotatable adjusting of gear.
Background technology
Automobile rearview mirror can reflect the situation of automobile rear, side and below, makes the driver can indirectly see the situation of these positions clearly, has enlarged driver's field range, improves ride safety of automobile.
Because the particularity of engineering truck, its vehicle body is long and higher, the back mirror of general-utility car can't be suitable for, the tradition engineering truck directly connects one higher by the bending rack on the vehicle body sheet metal, wider back mirror, bending rack generally is fixed, back mirror can be at the bending rack in the horizontal direction vertical rotary of the vertical pipeline section of bent support of going for a stroll, but the sight line position of different chaufeurs is different in operator's compartment, when being below or above back mirror, chaufeur need to be raised or reduce health and check back mirror, cause the driver's seat blind area, and driver's observation back mirror difficulty.
Summary of the invention
Can only be in the horizontal direction around the vertical axis vertical rotary for back mirror in the prior art, can't be applicable to different driver's observation uses, the deficiency that has blind area, the invention provides a kind of simple in structure, compact, it is firm to connect, and can make back mirror around horizontal axis in the vertical direction rotation drift angle, the conveniently and fast observing when satisfying different chaufeur normal driving, without blind area, the visual field, effectively guarantee the engineering truck gear rotation rearview mirror support in the driving safety visual field.
The technical solution used in the present invention is: a kind of engineering truck gear rotation rearview mirror support, comprise U-shaped bend pipe and Lian Che permanent seat, U-shaped bend pipe upper end connects engineering truck through sleeve pipe, its technical characterstic is described U-shaped bend pipe lower end activity cross-under connection car permanent seat one end, in the connection car permanent seat cooperation dish is set, cooperation is coiled an end face and is captiveed joint with end, U-shaped bend pipe lower end, cooperation dish other end is provided with a plurality of and boss by its longitudinal center line uniform around cooperation dish longitudinal center line, and boss is up-small and down-big trapezium structure and is the rounding structure perpendicular to the trapezium structure top of cooperation dish circumferencial direction; Connection car permanent seat other end captive joint connection car cooperates fluted disc, the connection car cooperates the fluted disc outer face to connect engineering truck, the connection car cooperates the fluted disc inner end surface to be provided with and a plurality ofly cooperates uniform and the recessed tooth by its longitudinal center line of fluted disc longitudinal center line around the connection car, and recessed tooth is the little trapezium structure of outer imperial palace and is the rounding structure perpendicular to the trapezium structure top that cooperates fluted disc axle circumferencial direction; Described cooperation is coiled between an end face and the connection car permanent seat spring is set, and spring one end holds out against connection car permanent seat, and the spring other end holds out against the cooperation dish makes cooperation dish other end boss cooperate the recessed tooth of fluted disc inner end surface to be the spring application interlocking pattern with the connection car.
Further, described U-shaped bend pipe lower end is connected to connection car permanent seat one end through the bearing freely-movable bearing.
Further, sealing cross-under one bonnet between described U-shaped bend pipe lower end and connection car permanent seat.
Again further, end, described U-shaped bend pipe lower end is the wedge post, and cooperation is coiled an end face and is provided with the wedge groove, and end, U-shaped bend pipe lower end wedge post locking is connected in cooperation and coils in the end face wedge groove and make cooperation dish and U-shaped bend pipe be the synchronous rotary state.
Adopt above technical scheme, the beneficial effect that the present invention reaches is: the connection car cooperates fluted disc to be fixedly connected on the engineering truck vehicle body, vertical section of the rotary U-type bend pipe back mirror is installed, the upper end pipe box of U-shaped bend pipe is movably connected on it the engineering truck, when different chaufeurs are driven, because the sight angle scope of chaufeur is different, back mirror can satisfy visual field requirement on the chaufeur horizontal direction around vertical section rotation of U-shaped bend pipe; Rotate around U-shaped bend pipe lower end, end, U-shaped bend pipe lower end interlock cooperates disc spins, boss on the initial cooperation dish pushes against the recessed tooth that the connection car cooperates fluted disc under acting force of the spring, the rotational force effect makes the relatively recessed tooth of the boss of cooperation dish push rotation and makes spring-compressed, when cooperating the disc spins certain angle, boss pushes against the recessed tooth realization anglec of rotation location that tight car cooperates fluted disc again under acting force of the spring, a plurality of boss of cooperation dish cooperate the connection car to cooperate a plurality of recessed tooth of fluted disc can satisfy the location of multistage angle rotation, this moment vertical period of U-shaped bend pipe rotates to an angle around its lower end, to adjust visual field requirement on the chaufeur vertical direction, avoid blind area, guarantee the driving safety of driving a vehicle.
The present invention connects the horizontal pipeline section employing of the hypomere boss of engineering truck, the power transmission arrangment of the mutual resilient snap of recessed tooth at U-bend, realize the multi-angle rotary location adjusting of the horizontal pipeline section of U-bend hypomere, the back mirror that satisfies on the vertical pipeline section of U-bend can rotate around horizontal axis, back mirror adjustment when being suitable for the different visuals field of different chaufeurs demand, make back mirror without blind area, the visual field, guarantee that driving safety uses.
