Abstract
Description
Technical Field
[0001] The utility model relates to the field of testing and surveying, in particular to a projection display device for measuring tools. Background Art
[0002] Laser ranging is widely used in the testing and mapping industry, and the test results are often directly displayed on the LCD or LED display screen embedded in the test device. Due to the size of the test device and the price of the display panel, the size of the display screen is usually small, resulting in a poor user experience. The patent of this invention projects the test results on the ground or wall in larger characters, which will inevitably bring users a better test experience. Summary of the invention
[0003] The utility model aims to solve the shortcomings in the prior art and provides a projection display device for measuring tools.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A projection display device for measuring tools comprises: a columnar shell, a strong light is arranged at one end of the columnar shell, a slot is opened on the columnar shell, a fixing ring is fixedly installed on the inner wall of the columnar shell, a digital display screen is installed on the fixing ring, and a lens group is sleeved on one end of the columnar shell.
[0006] Preferably, the digital display screen is placed upright between one focal length and two focal lengths of the lens in the lens group.
[0007] Preferably, a gasket is provided between the digital display screen and the lens group.
[0008] Preferably, the image side of the lens group is aligned with the ground or a wall, so that the inverted test result can be displayed on the ground or the wall, and the digital display is inverted and displayed on the digital display screen, so that the upright test result can be seen on the ground or the wall.
[0009] Preferably, a power cord is connected to one side of the high intensity lamp, and the power cord is connected to a power source.
[0010] Beneficial effects of the utility model:
[0011] 1. By aligning the image side of the lens group with the ground or wall, the digital test results are displayed on the ground or wall in an inverted manner on the digital display screen, which is convenient for the operator to directly observe the result numbers and reduce the size restrictions of the test device and the impact of the display panel price.
[0012] 2. The distance between one focal length and two focal lengths of the lens group can be changed by the digital display screen to facilitate observation by the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0019] Reference Figure 1-3 A projection display device for a measuring tool comprises a cylindrical shell 1, a strong light 2 is arranged at one end of the cylindrical shell 1, a slot 3 is opened on the cylindrical shell 1, a fixing ring 4 is fixedly installed on the inner wall of the cylindrical shell 1, a digital display screen 5 is installed on the fixing ring 4, and a lens group 6 is sleeved at one end of the cylindrical shell 1.
[0020] Specifically, the digital display screen 5 is placed upright between the first focal length and the second focal length of the lens in the lens group 6 .
[0021] Specifically, a gasket is provided between the digital display screen 5 and the lens group 6 .
[0022] Specifically, the image side of the lens group 6 is directed toward the ground or a wall, and the inverted test result can be displayed on the ground or the wall. The digital display screen 5 is inverted, and the upright test result can be seen on the ground or the wall.
[0023] Specifically, one side of the high intensity lamp 2 is connected to a power line, and the power line is connected to a power source.
[0024] Working principle: When the utility model is used, the operator obtains the conventional distance measurement result in advance, and displays the test result inverted on the digital display screen 5. The digital display screen 5 is located between one focal length and two focal lengths of the lens group 6. At this time, the closer the digital display screen 5 is to the one focal length point, the larger the image is, and the closer it is to the two focal length point, the smaller the image is. When the digital display screen 5 is located at the two focal length point, a real image of the same size as the inverted digital display screen 5 is formed.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
