Current Construction Machinery Market competitiveness strengthens day by day, and product gradually converts to comfortable type and service type from functional type, and client's also requirement to product quality is more and more higher, particularly to the most prominent in the comfortableness of man-machine manipulation and convenience.Follow-on driving mirror bracket is generally multistage gear, eliminate the trouble of use instrument, but it is difficult to control to the original position of gear, and gear can only rest on the direction set, it is easy to deviate appropriate position, the visual field is caused certain impact, also driving and human body is produced unexpected injury and there is certain potential safety hazard.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that the driving mirror bracket of a kind of prefastening step-less adjustment, it is possible to facilitate adjusting rearview mirror visual angle, makes driver can have good visual effect.
For solving above-mentioned technical problem, this utility model provides the driving mirror bracket of a kind of prefastening step-less adjustment, including base, mandrel and connecting rod, the vertical portion of described connecting rod free end is used for installing rearview mirror, the fixing end of connecting rod is fixed with described mandrel upper end, described base top is provided with the groove that can accommodate mandrel, mandrel by locking device with can in horizontal plane around axial line rotation by the way of activity be assemblied on base.
Further, described locking device includes spring and bolt, and base bottom is provided with the circular hole that can accommodate spring, is connected with mandrel by internal and external threads and is done prefastening and fix after bolt-through circular hole, and spring housing is located at bolt and tightens and be pressed in circular hole.
Further, described core shaft structure is that groove shapes matches with mandrel, and fits tightly with mandrel along axial line the most tapered tapered cylinders.
Further, described locking device also includes sealing gasket, and sealing gasket is located at the contact position of bolt and spring.
Further, described locking device also includes packing ring, and packing ring is located between sealing gasket and bolt.
Further, also include that dust cap, described dust cap are located at connecting rod and are fixed the junction of end and mandrel top.
Compared with prior art, this utility model is reached to provide the benefit that:
1) connecting rod of rotation rearview mirror support rotates around axial line in base with mandrel, rearview mirror can be driven to arrive other position in turning circumference, thus the visual angle between adjusting rearview mirror and driver, make different height, the driver of different work custom can have good visual effect；
2) bolt and mandrel are connected by internal and external threads and are done prefastening and fix, and pretension can improve bolted reliability, anti-loose ability and the fatigue strength of bolt, strengthens the compactness and rigidity connected；
3) by arranging spring between base and mandrel, the elastic force of spring can make mandrel arbitrarily rotate in base, realize rearview mirror step-less adjustment visual angle, need not by instrument during driving mirror bracket regulation, only need to be rotatably connected bar, and after rotating stopping, mandrel and base dependence elastic force are relatively fixed, nonvoluntary rotation, it is possible to increase the degree of accuracy of regulation.

Fig. 1 is the explosive view of this utility model driving mirror bracket.
In figure: 1, connecting rod；2, dust cap；3, mandrel；4, base；5, spring；6, sealing gasket；7, packing ring；8, bolt.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the driving mirror bracket of a kind of prefastening step-less adjustment that this utility model provides, including base 4, mandrel 3 and connecting rod 1, the vertical portion of described connecting rod 1 free end is used for installing rearview mirror, the fixing end of connecting rod 1 is fixed with described mandrel 3 upper end, described base 4 top is provided with the groove that can accommodate mandrel 3, mandrel 3 by locking device with can in horizontal plane around axial line rotation by the way of activity be assemblied on base 4.
Visible, in this utility model, the connecting rod 1 of driving mirror bracket can rotate in base 4 with mandrel 3, such that it is able to by the visual angle between bar 1 adjusting rearview mirror and driver that is rotatably connected, make different height, the driver of different work custom can have good visual effect.
As a kind of embodiment of the present utility model, as shown in Figure 1, described locking device includes spring 5 and bolt 8, the circular hole that can accommodate spring 5 it is provided with bottom base 4, bolt 8 is connected with mandrel 3 by internal and external threads and is done prefastening after running through circular hole to be fixed, spring 5 is set in bolt 8 and tightens and be pressed in circular hole, and circular hole does not connects with groove.Wherein pretension is divided into secondary to carry out, and bolt 8 can use plain bolt, and prefastening torque should meet this bolt torque values.Pretension can improve bolted reliability, anti-loose ability and the fatigue strength of bolt, strengthens the compactness and rigidity connected.The higher pretightning force reliability to connecting is all useful with the connected life-span.By arranging spring 5 between base 4 and mandrel 3, and spring 5 is in compressive state, when mandrel 3 arbitrarily rotates under certain External Force Acting in base 4, bolt 8 changes in the degree of depth threadeded with mandrel 3, but the telescopic resilience of compression spring 5 can make up the change of this degree of depth, bolt 8 is made still to be fastenedly connected with base 4 by mandrel 3, and then realize the visual angle that rearview mirror rotates between adjusting rearview mirror and driver with connecting rod 1 around axial line, need not by instrument during driving mirror bracket regulation, only need to be rotatably connected bar 1, and after rotating stopping, mandrel 3 relies on elastic force to be relatively fixed with base 4, nonvoluntary rotation, improve the degree of accuracy of regulation.
Further, described mandrel 3 structure is radius along the most tapered tapered cylinders of axial line, and groove shapes matches with mandrel 3, and fits tightly with mandrel 3.Relative fitting with cone bottom surface for cone bottom surface between mandrel 3 and base 4 groove, bore cylinder and relatively fit with cone cylinder, between the relative surface fitted, relative motion can produce frictional force, and relies on the damping between junction to prevent connecting rod 1 freely rotatable.This kind of fit structure of mandrel 3 and base 4 makes mandrel 3 preferably embed in base 4, it is possible to prevent mandrel 3 from arbitrarily rotating in base 4, and mandrel 3 and base 4 are after appropriate abrasion, still can normally play the effect of its structure.
In order to improve the sealing of base, described locking device also includes that sealing gasket 6, sealing gasket 6 are located at bolt 8 and the contact position of spring 5.Further, described locking device also includes that packing ring 7, packing ring 7 are located between sealing gasket 6 and bolt 8, are better assured that sealing.And sealing gasket 6 and packing ring 7 coordinate and can blocks dust, gravel enter in the circular hole of base 4, in case causing the inordinate wear to base 4 or obstruction, preferably protecting base 4, improving the working life of base 4.
Further, the fixing end of connecting rod 1 is provided with dust cap 2 with the junction on mandrel 3 top.Dust cover 2 is used for dust-proof, sealing, to prevent greasy dirt and water from entering mandrel 3 and the mating area of base 4, causes corrosion.And dust cover 2 may also function as decoration function.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
