Description

Angle measuring instrument for LED display panel

Technical Field

The invention relates to a measuring instrument, in particular to an angle measuring instrument for an LED display panel.

Background

Currently, in the LED display panel manufacturing industry, it is necessary to measure each index performance parameter of the LED display panel. It is known that the observation angle of the LED display panel is an important index for examining the quality of the LED display panel. However, in the prior art, there are generally two methods for detecting the observation angle of the LED display panel:

firstly, the panel is observed at a specific angle through subjective judgment, and the method has the following defects: the observation angle cannot be guaranteed, so that the test index of the display panel is inaccurate;

secondly, the angle is measured by taking the protractor and the panel as a reference, and then the position where an observer stands is obtained in a line-drawing mode.

Disclosure of Invention

In order to solve the problems in the background art, the invention provides an angle measuring instrument for an LED display panel.

The invention adopts the following technical scheme: an angle measuring instrument for an LED display panel comprises a mounting seat, a half gear, a worm, a mounting plate, a motor, a fixing frame, two protractors, two mounting rings and two pointers; the middle part of the mounting seat is fixedly connected with a vertically arranged half gear, the gear end of the half gear is meshed with a worm, one end of the worm is fixedly connected with the output end of a motor, two mounting rings are movably sleeved on the worm, the outer circumferential surfaces of the two mounting rings are fixedly connected with the inner surface of the mounting plate, the mounting plate is fixedly connected with the motor through a fixing frame, two ends of the mounting plate are slidably connected with the circumferential surfaces of corresponding protractors, the two protractors are vertically arranged and fixed at two ends of the mounting seat, two pointers are respectively fixed at two ends of the mounting plate and point to scale marks of the corresponding protractors, and a plurality of mounting grooves are arranged at the using end of the mounting plate; the periphery of each protractor is provided with a through groove along the circumferential direction, the lower surfaces of the two ends of the mounting plate are respectively fixed with a screw, and the two screws are inserted into the corresponding through grooves and are fixed through nuts.

Compared with the prior art, the invention has the beneficial effects that: the rotation of the motor output shaft drives the worm to rotate, and then drives the mounting plate to rotate along the half gear, so that the mounting angle of the mounting plate is changed.

Drawings

Detailed Description

The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the invention, rather than all embodiments, and all other embodiments obtained by those skilled in the art without any creative work based on the embodiments of the present invention belong to the protection scope of the present invention.

The first embodiment is as follows: as shown in fig. 1, the invention discloses an angle measuring instrument for an LED display panel, which comprises a mounting base 1, a half gear 3, a worm 4, a mounting plate 6, a motor 7, a fixing frame 8, two protractors 2, two mounting rings 5 and two pointers 9; the middle of the mounting seat 1 is fixedly connected with a vertically arranged half gear 3, the gear end of the half gear 3 is meshed with a worm 4, one end of the worm 4 is fixedly connected with the output end of a motor 7 through a coupler, the worm 4 is movably sleeved with two mounting rings 5, the outer circumferential surfaces of the two mounting rings 5 are fixedly connected with the inner surface of a mounting plate 6, the mounting plate 6 is fixedly connected with the motor 7 through a fixing frame 8, two ends of the mounting plate 6 are slidably connected with the circumferential surfaces of the corresponding protractors 2, the two protractors 2 are vertically arranged and fixed at two ends of the mounting seat 1, two pointers 9 are respectively fixed at two ends of the mounting plate 6, the two pointers 9 point to the scale lines A of the corresponding protractors 2, and the using end of the mounting plate 6 is provided with a plurality of mounting grooves B; the circumference of each protractor 2 is provided with a through groove C along the circumferential direction, the lower surfaces of the two ends of the mounting plate 6 are fixed with screws 11, and the two screws 11 are inserted into the corresponding through grooves C and fixed through nuts 10.

The second embodiment is as follows: as shown in fig. 1, the present embodiment is further described with respect to the first embodiment, and the plurality of mounting grooves B are arranged in parallel from top to bottom.

When the angle change observation device is used, the motor 7 is started (the motor 7 is controlled by a remote controller), the worm 4 is driven to rotate by the rotation of the output shaft of the motor 7, the mounting plate 6 is driven to rotate along the half gear 3, the change of the angle of the LED display panel is realized, the two protractors 2 are arranged at the same time, the pointer 9 pointing to the protractors 2 is arranged on the mounting plate 6, and when the angle of the LED display panel is changed, the angle change of the LED display panel can be observed directly through the position change of the pointer 9 on the scale mark A of the corresponding protractor 2.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
