Description

Angle adjustment device of LCD monitor {A APPARATUS OF AN ANGLE ADJUSTER FOR LCD MONITOR}

The present invention relates to an angle adjusting device of an LCD monitor, and in particular, its structure is simple and easy to assemble, and its purpose is to provide an angle adjusting device that is capable of adjusting torque by frictional force according to the weight of the monitor.

In general, a high elastic spring is installed at the rear of the LCD monitor so that the monitor can be adjusted up and down according to the user's eye level, and the angle of the monitor is adjusted by using the elasticity of the spring, or a special circular disc is formed at the hinge. A plurality of plates were superimposed and the angle adjusting device of the monitor using the frictional force of the disc plate was used by pressing the disc plate in the axial direction.

However, in the conventional angle adjusting device using the elastic spring as described above, in order to maintain a constant torque while fixing the monitor at a constant angle, a plurality of spring washers and nuts, etc. must be installed at both sides of the hinge, which makes the structure complicated. There was a problem, and it was difficult to adjust a constant torque.

In addition, the angle adjusting device using a special disc plate is used by the friction force generated by pressing a plurality of overlapping disc plate, the friction force is unnecessarily large at the initial stage of manufacturing, and the friction force is reduced due to the wear of the disc plate due to long time use The support is hindered, and in the case of the above, there is a problem in that many accessories are consumed because the worn disc plate needs to be replaced.

In addition, in order to prevent abrasion of the disk plate as described above, a special material having a high hardness or a special surface of the disk plate was used, but since such a disk plate is expensive, there is a problem that the overall unit cost of the product increases.

In order to solve the above problems, the shaft is coupled to the center of both support portions of the fixing bracket fixed to the pedestal, and each of the rotation shafts coupled to the shaft after coupling the monitor fastening bracket to the outside of the both sides of the fixing bracket. Combining from the outside of the shaft is configured to adjust the angle by the torque by the frictional force of the sliding hole of the shaft and the sliding shaft.

In the drawings, reference numeral 100 denotes a monitor and 101 denotes a pedestal.

Referring to the operation of the present invention is as follows.

As described above, the present angle adjusting device composed of the fixing bracket 10, the shaft 20, the rotation shaft 30, and the monitor fastening bracket 50 is disposed between the support members 13 on both sides of the fixing bracket 10. A coupling groove 22 formed at both ends of the shaft 20 is coupled to the shaft 20 into which the through ring 70 is inserted, and the upper and lower outer peripheries of the inner side of the hinge hole 11 of the support bracket 13 are fixed. Inserted to be coupled to the engaging projection 12 formed in the projection.

As described above, the shaft 20 is sandwiched between the support portions 13 of the fixed bracket 10, and then both the rotation support parts 54 of the monitor fastening bracket 50 are fitted to the outside of the both support parts 13 of the fixed bracket 10. After the rotation shaft 40 is coupled to both sides of the shaft 20 coupled between the support portions 13 on both sides of the fixed bracket (10).

At this time, the rotation shaft 40 is coupled to the oil storage groove 41 is a plurality of oil storage groove 41 formed on the surface of the sliding portion 42 formed on one side to prevent the frictional heat, such as grease, oil is applied to the oil storage groove 41 After receiving the sliding portion 42 is in close contact with the sliding hole 21 formed on both sides of the shaft 20, the side end of the sliding portion 42 of the spring 70 inserted into the shaft 20 It is in close contact with both ends.

Meanwhile, a washer 30 which prevents abrasion of the rotation support part 54 and the support part 13 between the rotation support part 54 of the monitor fastening bracket 50 and the support part 13 of the fixed bracket 10 coupled as described above. ) Will be inserted respectively.

Insert the fastening nut 61 into the fastening nut insertion groove 42 of the one side rotating shaft 40 coupled as described above, and then insert the fastening bolt 60 into the rotating shaft 40 coupled to the other side of the fastening nut ( 61) can be screwed together.

At this time, the fastening bolt 60 is screwed as described above, the screw is formed only on one side portion, and the fastening bolt 60 is no longer rotated after screwing the fastening nut 61 with a predetermined length, therefore, the rotation shaft 40 Sliding portion 42 of the) is coupled to the sliding hole 21 of the shaft 20 by pressing a constant force on both sides.

In addition, the rotation shaft 40 coupled as described above is supported by a spring 70 inserted into the shaft 20 by the side end of the sliding part 42 so that the sliding part 42 is a sliding hole 21. ) Can be prevented from over-adhering.

In addition, since oil is accommodated in the oil storage groove 41 formed on the outer circumferential surface of the sliding portion 42 of the rotating shaft 40, frictional heat generated by the sliding portion 42 and the sliding hole 21 of the shaft 20. It can prevent, and can be used for a long time without replenishing the frequent oil by the friction heat.

The angle adjusting device combined as described above is fixed to the lower portion of the fixing bracket 10 by using a fixing means such as a bolt to the pedestal 101, the fastening bracket body of the monitor fastening bracket 50 as shown in FIG. (52) Fasten the monitor 100 to the fastening hole 51 formed in the center by a hinge.

When adjusting the angle of the fastened monitor 100 as described above, when the user applies a force up and down to the monitor 100, the monitor fastening bracket 50 and the monitor fastening bracket 50 fastened to the monitor 100 are rotated on both sides. The rotating shaft 40 to which the support part 54 is fixed is rotated in the same direction.

At this time, the rotating shaft 40 is rotated on both sides of the sliding hole 21 of the shaft 20 is fixed to the engaging grooves 22 of the upper and lower ends of the outer peripheral edges are coupled to the locking projections 12 of the fixing bracket 10. The sliding part 42 is slid to generate a friction force, and the rotation shaft 40 and the monitor fastening bracket 50 rotate while receiving the torque by the friction force.

After adjusting the rotating monitor 100 to a desired angle as described above, if the force applied to the monitor 100 is stopped, the sliding hole 21 of the shaft 20 and the sliding part 42 of the rotating shaft 40 are generated. It is fixed at an angle adjusted by the torque due to the frictional force.

In addition, the monitor 100 rotated as described above has an angle control protrusion 14 protruding from both side support portions 13 of the fixing bracket 10 formed at both ends of the rotation support portions 54 of the monitor fastening bracket 50. Since it is coupled to the angle control groove 53, it can only be rotated within a certain angle before and after it can prevent the monitor from being rotated and damaged by excessive force of the user.

Then, the sliding part 41 of the rotation shaft 40 is coupled to the shaft 20 by combining the fastening bolts 60 having different lengths of screws formed only by a predetermined length of the fastening bolts 60 coupled with the fastening nuts 61. By adjusting the friction force generated by pressing the sliding hole 21 of the monitor 100 can be used to adjust the appropriate torque according to the size or weight of the

Since the angle adjusting device of the present invention as described above adjusts the angle using the torque by the friction force, there is an effect that can be adjusted to the desired angle with a small force without applying excessive force, and according to the weight of the monitor, the appropriate torque easily There is an effect that can be adjusted, and the effect of maintaining a constant torque without changing the torque even if used for a long time.
