[0002] A distance meter is an instrument used to accurately measure the spatial distance between objects. For example, laser ranging technology uses a laser beam emitted by the instrument. After hitting a target object and reflecting back, the instrument records the time it takes for the laser to travel back and forth. By leveraging the principle of the constant speed of light, this technology can be used in the real estate industry to measure the interior dimensions of a house, from the length and width of a room to the height of the house, providing accurate data for home sales and renovations.

Therefore, to address these deficiencies, a variable-magnification line spacing detector is proposed to address the above issues. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 3 The present invention provides an embodiment of a variable-magnification line spacing detector, comprising a housing 1. A fixed frame 2 is fixedly connected to the front and rear sides of the housing 1 to restrict the movement of subsequent components. Two limiting openings 3 are defined on the front and rear inner walls of the fixed frame 2 to provide space for the engagement of subsequent components. A protective plate 20 is slidably connected to the top side of the housing 1 to protect it from the external environment. Side blocks 4 are fixedly connected to the front and rear sides of the protective plate 20 to transmit the sliding force of the protective plate 20 to the side blocks 4. A connecting plate 5 is fixedly connected to the bottom side of the side blocks 4. The sliding force is transmitted to the connecting plate 5 by the side blocks 4, allowing the connecting plate 5 to slide horizontally left and right. A sliding plate 6 is fixedly connected to the bottom side of the connecting plate 5. The sliding plate 6 not only restrains the connecting plate 5 and prevents it from sliding, but also transmits the sliding force of the connecting plate 5 to the sliding plate 6. Elastic members 7 are fixedly connected to the front and rear sides of the sliding plate 6 to constrain the sliding plate 6.

[0034] Reference Figure 1 、 Figure 4 and Figure 5 The top side of the inner wall of the protective plate 20 is fixedly connected with a reset assembly for resetting subsequent components. The reset assembly includes multiple springs 8. The top ends of the multiple springs 8 are fixedly connected to the top side of the inner wall of the protective plate 20, and the bottom ends of the multiple springs 8 are fixedly connected to the limit plate 9. The two ends of the spring 8 are fixed so that the spring 8 can be evenly stressed. The outer side of the limit plate 9 is slidably connected to the inner wall of the left end of the protective plate 20. The limit plate 9 is restricted by the protective plate 20 so that the limit plate 9 can slide vertically up and down. The bottom side of the reset assembly is fixedly connected with a connecting plate 10. The bottom side of the limit plate 9 is fixedly connected to the top side of the connecting plate 10. The limit plate 9 provides support to the connecting plate 10 and prevents the connecting plate 10 from slipping. The bottom side of the connecting plate 10 is fixedly connected with a cleaning plate 11 for cleaning the surface of 1. The bottom side of the cleaning plate 11 is slidably connected to the top side of the housing 1 of the variable magnification line spacing detector. The outer portion of the connecting plate 10 is slidably connected to the inner wall of the left end of the protective plate 20, and the connecting plate 10 is restricted by the connecting plate 10 so that the connecting plate 10 can slide vertically up and down. The outer portion of the cleaning plate 11 is slidably connected to the inner wall of the left end of the protective plate 20, and the cleaning plate 11 is restricted by the protective plate 20 so that the cleaning plate 11 can slide vertically up and down.

[0035] Reference Figure 1 、 Figure 2 and Figure 6 The right side of the protective plate 20 is fixedly connected to the fixed plate 12, and the sliding force is transmitted to the fixed plate 12 through the protective plate 20. The bottom side of the fixed plate 12 is fixedly connected to the transmission plate 13, and the sliding force of the fixed plate 12 is transmitted to the subsequent components through the transmission plate 13. The top left end of the transmission plate 13 is fixedly connected to the transmission column 14, which pushes the subsequent components to slide after receiving the sliding force of the transmission plate 13. The external sliding connection of the transmission column 14 is connected to the placement plate 15, and the interior of the placement plate 15 is provided with an inclined opening 16. Through the inclined opening 16, the transmission column 14 can push the placement plate 15 to slide back and forth. The external sliding connection of the placement plate 15 is connected to the inner wall of the variable magnification line spacing detector housing 1. The front end of the placement plate 15 is fixedly connected to two fixed rods 17 for supporting and limiting subsequent components. The external sliding connection of the two fixed rods 17 is connected to two sliding assemblies for clamping objects. The sliding assembly includes two sliding plates 18. The exteriors of both sliding plates 18 are slidably connected to the interior of the front end of the placement plate 15. The placement plate 15 constrains the sliding plates 18, ensuring stable sliding. The interiors of both sliding plates 18 are slidably connected to the exteriors of two fixed rods 17. Springs 19 are sleeved around the left and right ends of each fixed rod 17. The proximal ends of multiple springs 19 are fixedly connected to the distal ends of the two sliding plates 18, constraining and securing the springs 19 so that they are evenly loaded.

[0036] Working principle: When the protective plate 20 slides on the top side of the variable magnification line distance detector housing 1, the side blocks 4 on the front and rear sides of the protective plate 20 move accordingly, and the rear side block 4 will drive the connecting plate 5 to slide to the right, and then drive the sliding plate 6 to slide to the right, thereby driving the elastic member 7 to slide and disengage from the restriction of the limiting opening 3, until the protective plate 20 slides to be fully opened. At this time, the elastic member 7 will slide to the rightmost side of the fixed frame 2 and engage the elastic member 7 inside the limiting opening 3. At the same time, when the protective plate 20 moves, the spring 18 is in a compressed state, and then gives the limiting plate 9 a downward sliding force, thereby pushing the connecting plate 10 to slide downward, and then pushing the cleaning plate 11 to slide downward and make it fit 1. The cleaning plate 11 slides on the top side of the variable magnification line distance detector housing 1 as the protective plate 20 moves, thereby cleaning the surface of the housing 1 without the need to clean it specifically, thereby improving work efficiency.

[0037] During the sliding process, the protective plate 20 will also drive the fixed plate 12 to slide, thereby driving the transmission plate 13 to slide, and then pushing the transmission column 14 to slide. By utilizing the inclined opening 16 opened inside the placement plate 15, the transmission column 14 can push the placement plate 15 to slide forward and expose the front end of the placement plate 15, and at the same time, the pen can be clamped between the two sliding plates 18, and the sliding plate 18 can squeeze the spring 2 19 during the sliding process, so that the spring 2 19 can store elastic potential energy, and then give the sliding plate 18 a force in the opposite direction to fix the pen, and then the pen can be quickly taken out for recording, thereby improving its convenience.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
