Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and in particular to a roof prism offset inspection tool. Background Technology

[0002] Two mutually perpendicular reflecting surfaces are called roof surfaces, and a prism with roof surfaces is called a roof prism. Roof prisms are small in size and can keep the objective lens and eyepiece on the same straight line. Therefore, they are often used in very compact binoculars. Roof prisms existed in the early days of telescope development. They can keep the outgoing light and the incident light on the same straight line. Their tubes are straight, and their sense of distance, stereoscopic vision, and size are closer to those of the naked eye. During the use of roof prisms, relevant measurements need to be taken to obtain relevant data about the roof prism.

[0003] The patent with publication number CN216385383U discloses a ridge prism deflection gauge, which includes a base, a first fixing block and a second fixing block. The first fixing block is fixedly installed on the left side above the base. The right side of the first fixing block is set to a 45° rightward tilt. The second fixing block is movably installed on the right side of the base. The left side of the second fixing block is set to a 45° leftward tilt. A first baffle is provided above the first fixing block.

[0004] In the above technology, the first screw is rotated by the first rotating head, so that the support plate moves left and right along the axial direction of the first screw to fix the ridge prism and ensure that the ridge prism will not shift during the test. However, the table surface is prone to local depressions when it is pressed by heavy objects for a long time, resulting in unevenness on the table surface. Therefore, the center of gravity of the gauge will be unstable, which will affect the measurement results of the ridge prism. Therefore, an innovation is made to this technology. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ridge prism offset gauge, comprising a base, an anti-slip pad, an auxiliary frame, and a dial indicator. The anti-slip pad is disposed at the bottom of the base, the auxiliary frame is disposed at the top of the base, and the dial indicator is disposed on one side of the auxiliary frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This utility model discloses a ridge prism offset gauge, which is equipped with a vertical plate, a vertical frame, a movable block, an arc plate, a support bar, and a powerful suction cup. The movable block can move up and down at one end of the vertical rod. With the connection of the arc plate, it also drives the powerful suction cup to move up and down, thereby adjusting the position and height of the powerful suction cup. Through this structure, the powerful suction cup can be adsorbed according to different platform heights, improving the flexibility of the gauge. The adsorption of the powerful suction cup to the platform further enhances the stability of the base. The four powerful suction cups are located at the four corners of the base, increasing the adsorption area on the platform.

The threaded connection of the three can limit and fix the vertical frame and the moving block. By rotating the limiting bolt in the opposite direction, one end of the limiting bolt gradually disengages from the threaded hole, thereby allowing the vertical plate to be separated from one side of the base for easy replacement of the damaged powerful suction cup.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a ridge prism offset gauge:

[0023] Example 1:

[0024] like Figure 1-3As shown, a ridge prism offset gauge includes a base 1, an anti-slip pad 2, an auxiliary frame 3, and a dial indicator 15. The anti-slip pad 2 is located at the bottom of the base 1, the auxiliary frame 3 is located at the top of the base 1, and the dial indicator 15 is located on one side of the auxiliary frame 3. Two vertical plates 4 are provided on both sides of the base 1. Arc-shaped blocks 5 are provided on the top of each of the four vertical plates 4. Vertical frames 7 are provided on one side of each of the four vertical plates 4. Vertical rods 8 are provided inside each of the four vertical frames 7. A movable block 9 is fitted at one end of each of the four vertical rods 8. A support bar 11 is provided on one side of each of the four movable blocks 9. A strong suction cup 12 is provided at one end of each of the four support bars 11. Through this structure, the strong suction cup 12 can adhere to different platform heights, improving the flexibility of the gauge. The adhesion of the strong suction cup 12 to the platform further enhances the stability of the base 1. The four strong suction cups 12 are located at the four corners of the base 1, increasing the adhesion area to the platform.

[0025] Example 2:

[0026] Based on Example 1, such as Figure 1 and Figure 4 As shown, positioning strips 13 are provided on both sides of the four vertical frames 7. One end of each of the eight positioning strips 13 is connected to the internal threads of the eight recesses and multiple positioning holes 14. Two threaded holes are provided on both sides of the base 1. Limiting bolts 6 are provided on one side of each of the four arc blocks 5. One end of each of the four limiting bolts 6 is connected to the internal threads of the four threaded holes. This utility model provides a ridge prism deflection gauge. By setting up arc blocks 5, limiting bolts 6, positioning strips 13 and positioning holes 14, after the bottom surface of the powerful suction cup 12 is attached to the table surface for adsorption, one end of each of the two positioning strips 13 is embedded into the recesses and positioning holes 14. The threaded connection of the three can limit and fix the vertical frame 7 and the moving block 9.

[0027] Working principle: Two mutually perpendicular reflecting surfaces are called roof surfaces, and a prism with roof surfaces is called a roof prism. Roof prisms are small in size and can align the objective lens and eyepiece in a straight line. Therefore, they are often used in extremely compact binoculars. Roof prisms existed in the early days of telescope development. They keep the outgoing and incoming light in a straight line. Their tubes are straight, and their sense of distance, stereopsis, and size are closer to that of the naked eye. During the use of a roof prism, relevant measurements need to be taken to obtain the roof prism's position. Regarding the prism data, the aforementioned technology uses a first rotating head to rotate the first lead screw, causing the support plate to move left and right along the axial direction of the first lead screw, thus fixing the ridge prism and ensuring that it will not shift during the testing process. However, under the pressure of heavy objects for a long time, the table surface is prone to local depressions, resulting in unevenness. This can cause instability in the gauge, affecting the measurement results of the ridge prism. Therefore, an innovation is made to this technology: an anti-slip pad 2 is placed on the table, and the ridge prism is placed on the auxiliary frame 3. Within the groove, the movable block 9 moves according to the unevenness of the table surface. The movable block 9 can move up and down at one end of the vertical rod 8. Connected by the arc-shaped plate 10, this causes the powerful suction cup 12 to move up and down, thus adjusting its position and height. This structure allows the powerful suction cup 12 to adhere to different table heights, improving the flexibility of the inspection tool. The powerful suction cup 12 can adhere to metal surfaces, glass, plastic, and wood. The adhesion between the powerful suction cup 12 and the table surface further enhances the bottom... The base 1 is sturdy, with four powerful suction cups 12 located at the four corners of the base 1, increasing the area for adsorption on the table surface. After the bottom surface of the powerful suction cup 12 is attached to the table surface, one end of the two positioning strips 13 is embedded into the recess and positioning hole 14. The threaded connection of the three can limit and fix the vertical frame 7 and the moving block 9. By rotating the limiting bolt 6 in the opposite direction, one end of the limiting bolt 6 gradually disengages from the threaded hole, thereby allowing the vertical plate 4 to be separated from one side of the base 1 for easy replacement of the damaged powerful suction cup 12.
