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 driver can indirectly see the situation of these positions clearly, has expanded driver's field range, improves ride safety of automobile.
Particularity due to engineering truck, its vehicle body is long and higher, the back mirror of general-utility car cannot be suitable for, tradition engineering truck directly connects one higher by the bending rack on vehicle body sheet metal, wider back mirror, bending rack is generally fixed, back mirror can be on bending rack around the vertical pipeline section of bending rack vertical rotary in the horizontal direction, but the sight line position of different chaufeurs is different in operator's compartment, when below or above back mirror, chaufeur need to be raised or reduce health and check back mirror, cause driver's seat blind area, and chaufeur is observed back mirror difficulty.
Summary of the invention
Can only be in the horizontal direction around vertical axis vertical rotary for back mirror in prior art, cannot be applicable to different chaufeurs and observe use, there is the deficiency of 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 meeting different chaufeur normal driving, without blind area, effectively guarantee the gear rotation rearview mirror support for engineering truck in the driving safety visual field.
The technical solution used in the present invention is: gear rotation rearview mirror support for a kind of engineering truck, 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 activity cross-under connection car permanent seat one end, described U-shaped bend pipe lower end, in connection car permanent seat, a cooperation dish is set, cooperation is coiled an end face and is fixedly connected with end, U-shaped bend pipe lower end, cooperation dish other end is provided with a plurality of uniform and by the boss of its longitudinal center line around cooperation dish longitudinal center line, boss is up-small and down-big trapezium structure and is rounding structure perpendicular to the trapezium structure top of cooperation dish circumferencial direction, the connection car permanent seat other end is fixedly connected with connection car and coordinates fluted disc, connection car coordinates fluted disc outer face to connect engineering truck, connection car coordinates fluted disc inner end surface to be provided with and a plurality ofly around connection car, coordinates that fluted disc longitudinal center line is uniform and by the recessed tooth of its longitudinal center line, recessed tooth is the trapezium structure that outer imperial palace is little and coordinates the trapezium structure top of fluted disc axle circumferencial direction to be rounding structure perpendicular to connection car, described cooperation is coiled between an end face and connection car permanent seat a spring is set, and spring one end holds out against connection car permanent seat, and the spring other end holds out against cooperation dish makes cooperation dish other end boss coordinate the recessed tooth of fluted disc inner end surface to be spring application interlocking pattern with connection car.
Further, described U-shaped bend pipe lower end is connected to connection car permanent seat one end through bearing freely-movable bearing.
Further, between described U-shaped bend pipe lower end and connection car permanent seat, seal cross-under one bonnet.
Again further, end, described U-shaped bend pipe lower end is Tapered Column, and cooperation is coiled an end face and is provided with webge slot, and end, U-shaped bend pipe lower end Tapered Column locking is connected in cooperation and coils in an end face webge slot and make cooperation dish and U-shaped bend pipe be synchronous rotary state.
Adopt above technical scheme, the beneficial effect that the present invention reaches is: connection car coordinates fluted disc to be fixedly connected on engineering truck vehicle body, vertical section of rotary U-type bend pipe back mirror is installed, the upper end pipe box of U-shaped bend pipe is movably connected on it engineering truck, when different chaufeurs are driven, because the sight angle scope of chaufeur is different, back mirror can meet visual field requirement in chaufeur horizontal direction around vertical section of rotation of U-shaped bend pipe, around U-shaped bend pipe lower end, rotate, end, U-shaped bend pipe lower end interlock coordinates disc spins, boss on initial cooperation dish pushes against the recessed tooth that connection car coordinates fluted disc under acting force of the spring, rotational force effect makes the boss of cooperation dish push to rotate relative to recessed tooth and makes spring-compressed, when coordinating disc spins certain angle, boss again pushes against the recessed tooth of tight car cooperation fluted disc and realizes anglec of rotation location under acting force of the spring, a plurality of boss of cooperation dish coordinate connection car to coordinate a plurality of recessed tooth of fluted disc can meet the location of multistage angle rotation, now vertical section of U-shaped bend pipe rotates to an angle around its lower end, to adjust visual field requirement on 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, the multi-angle rotary location of realizing the horizontal pipeline section of U-bend hypomere regulates, the back mirror meeting on the vertical pipeline section of U-bend can rotate around horizontal axis, back mirror adjustment while being suitable for the different visuals field of different chaufeurs demand, make back mirror without blind area, guarantee that driving safety is used.
