Abstract

The utility model relates to a TV base steering device, which is designed a TV base into a combination with an upper bottom and a lower base. The middle port of the rectangular upper bottom flat surface is made into a disk-shaped dummy club, and the middle part of the disk-shaped lower base surface is hollowed into a round-pool-shaped basin. Circle-shaped ball grooves are both dug on the upper bottom and the lower base of the disk surfaces; spheroidal balls are arranged in the lower ball grooves in spread ball type. The dummy club of the upper bottom is embedded into the basin of the lower base; the TV base can freely turn with the function of the top and bottom ball grooves and the balls. Therefore, in order to connect with the upper bottom and a lower base, a positioning slot is dug on the round elevation around the dummy club periphery on the upper bottom, and a screw positioning pin is provided with the left and right ends of the dish of the lower base; the upper bottom and the lower base are connected by using the positioning pin and the positioning slot. Adopting the scheme, people can watch TV from different various angles as long as turn the TV body lightly.

Description

TV base steering device

The utility model is a kind of television set base that can turn to, and belongs to a kind of device of mechanical type.

At present, known television set base all is to fuse with body, must move whole machine body when different directions is seen TV, and is very inconvenient, must design the base that can turn in order to address this problem.

The purpose of this utility model provides a kind of television set base transfer for people just, makes people watch TV easily under the occasion of different angles, especially can transfer direction easily and watch effect.

The purpose of this utility model is achieved in that the television set base is respectively by the upper base 1 and 2 members dimerous of going to the bottom, its upper base 1 is a boss in a patty of middle part, rectangle baseplane projection, it is gone to the bottom 2 is recessed dishes of a round pool shape, the boss of its upper base 1 and 2 the recessed dish of going to the bottom constitute the inserted combined member of convex-concave, on 1 boss disk of upper base, dig the circle of a flute profile, this is last ball grooves 3, in 2 the recessed dish of circle of going to the bottom, also dig the circle of a flute profile on the baseplane, this is following ball grooves 4, and, the same ball grooves is vertical symmetry up and down, its ball 5 is balls of garden sphere, and, be and spread pearl formula ground device in following ball grooves 4 the insides, the boss of upper base 1 is filled in 2 the recessed dish of going to the bottom, and by being clipped in the effect of ball in the ball grooves up and down, just can realize that the combining structure that television set freely turns to turns to base, simultaneously, for as do not make the disconnection of going to the bottom during moving television set, thereby, be again under the prerequisite that does not hinder rotation, digging location notch 6 on the facade around the boss platform of upper base 1, at the upright screw hole 7 that is equipped with the band screw thread of helping of 2 the recessed dish transverse ends of circle of going to the bottom, boss head spiral dowel 8 is housed in screw hole 7, insert in the location notch 6 by alignment pin 8, just making goes to the bottom can freely rotate and can not disconnect separation.

Owing to adopted such scheme, just brought great convenience when under the occasion of different directions, watching TV for people.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the vertical section structural map of facing of the present utility model.

Fig. 2 looks up the last bottom plan view of seeing.

Fig. 3 is the plan view from above of going to the bottom.

Among the figure 1, upper base 2, go to the bottom 3, go up ball grooves 4, ball grooves 5, ball 6, location notch 7, setting screw eye 8, spiral dowel down.

Said that upper base 1 is the boss that has the round pie of a projection on the rectangular bottom surface of television set drain pan.

Said going to the bottom 2 is recessed dishes that are round pool shape of inlaying upper base 1 boss.

The said ball grooves 3 of must going up is the circles that enclose the inboard groove shape that digs on the boss baseplane at upper base 1, and its bottom land is the garden arcuation.

The said slot rolling 4 that must descend is the groove shape circles that dig at 2 the recessed dish inner bottom surface of going to the bottom, and its bottom land is circular-arc.And with last ball grooves vertical symmetry about in the of 3.

Said ball 5 be rolling of garden sphere, and is and spreads pearl formula ground device 4 li of ball grooves down, constitutes the transfer structure that can freely rotate together with last slot rolling 3.

Said that location notch 6 is the hollow grooves of a circle that dig on upper base 1 boss periphery facade, its bottom land is the circular-arc end.

Said that screw eye 7 is at the upright screw hole of helping the band screw thread that is equipped with that is the both sides symmetry of the 2 recessed dish transverse ends of going to the bottom.

Said spiral dowel 8 be device in two ends screw hole 7, its top bald head inserts location notch 6 the insides, and machine base can flat shape be rotated, but on go to the bottom and connect together and can not separate.
