Description

Technical Field

[0001] The utility model relates to the technical field of topographic auxiliary measuring rulers, in particular to a novel topographic auxiliary measuring ruler. Background Art

[0002] When athletes and coaches prepare for a game, they need to establish goal points (such as scoring points, milestones, etc.) and standing points (such as the starting line, starting point, etc.) for the game. When planning a trip, it is necessary to determine the destination (goal point) and the meeting point or standing point at each location. In an emergency, such as a fire, earthquake, or other disaster, people need to know the location of safe standing points or shelters.

[0003] The target point and standing point are generally established using the "hanging wire method". The steps of the hanging wire method are as follows: select a reference point of known position, which can be a corner point of a building, a control point or other stable fixed point. Hang a rope or chain at the reference point to ensure that it remains vertical. The length of the rope or chain should be determined according to the height of the target point or standing point to be determined. Use a tape measure, measuring rope or other measuring tool to measure from the reference point along the rope or chain to the position of the target point or standing point. Make marks on the rope or chain to indicate the position of the target point or standing point.

[0004] This method is difficult for beginners to use and difficult to understand and master. And for the user, the use of the "drop line method" is affected by factors such as unstable drop line, outdoor wind force, aiming deviation, etc., resulting in large errors in the observation results. Utility Model Content

[0005] The utility model aims to solve the problem that the "dropping line method" mentioned in the background technology is unstable and easily affected by wind, and proposes a new type of topographic auxiliary measuring ruler that is stable and not easily affected by wind.

[0007] A leveling mechanism, the leveling mechanism is installed on one side of the resin damping hinge, the leveling mechanism comprises a limit block, the secondary ruler abuts against the limit block, and the leveling mechanism drives the limit block to rotate to a vertical position;

[0008] A fixing component is installed on one side of the resin damping hinge, and the fixing component fixes the limit block in a vertical state.

[0009] Optionally, the leveling mechanism includes a mounting plate fixedly mounted on one side of the resin damping hinge, a sphere rotatably mounted on the mounting plate, a telescopic rod fixedly mounted on the sphere, and a counterweight block fixedly mounted on the sphere, and the limit block is fixedly mounted on the telescopic rod.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] The utility model drives the ball to rotate through the counterweight block. The telescopic rod can be rotated to a vertical state. The notch squeezes and fixes the ball by rotating the handle in the opposite direction, and the ball cannot rotate at this time.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figure 1 As shown, the utility model proposes a novel topographic auxiliary ruler, including a resin damping hinge 1, a main ruler 2 is fixedly installed at one end of the resin damping hinge 1, and a secondary ruler 3 is fixedly installed at the other end of the resin damping hinge 1. The main ruler 2 and the secondary ruler 3 are both made of transparent acrylic plates. The main ruler 2 and the secondary ruler 3 can be rotated by the resin damping hinge 1, and the angle between the main ruler 2 and the secondary ruler 3 can be changed. The main ruler 2 is provided with a first through slot 201, and first scales 202 are provided on both sides of the first through slot 201. The secondary ruler 3 is provided with a second through slot 301, and second scales are provided on both sides of the second through slot 301. The center lines of the first through slot 201 and the second through slot 301 are on the same plane. The main ruler 2 is placed flat on the drawing board, and the secondary ruler 3 is rotated to a vertical state. The second through slot 301 on the secondary ruler 3 replaces the "drop line" at this time. The three-point one-line method can be used to clearly observe the target through the second through slot 301 on the secondary ruler 3, and then the line to the observed target is directly drawn through the first through slot 201 on the main ruler 2. It can improve the observation accuracy and the operation is simple and fast.

[0024] like Figure 2-3As shown, the leveling mechanism is installed on one side of the resin damping hinge 1, the leveling mechanism includes a limit block 403, the secondary ruler 3 is against the limit block 403, and the leveling mechanism drives the limit block 403 to rotate to a vertical position. The leveling mechanism includes a mounting plate 4 fixedly mounted on one side of the resin damping hinge 1, a sphere 401 rotatably mounted on the mounting plate 4, a telescopic rod 402 fixedly mounted on the sphere 401, and a counterweight 404 fixedly mounted on the sphere 401, and the limit block 403 is fixedly mounted on the telescopic rod 402. The telescopic rod 402 is located on the upper side of the mounting plate 4, and the counterweight 404 is located on the lower side of the mounting plate 4, and the telescopic rod 402 and the counterweight 404 are in a coaxial position. When the sphere 401 can rotate freely on the mounting plate 4, and the center of gravity connection line of the telescopic rod 402 and the counterweight 404 is not in a vertical position, the sphere 401 will be driven to rotate under the action of the counterweight 404. Then the telescopic rod 402 is driven to rotate, and the telescopic rod 402 can be rotated to a vertical state. At this time, the telescopic rod 402 is stretched to drive the limit block 403 to rise, so that the limit block 403 can contact the secondary ruler 3. Thus, the limit block 403 can limit the position of the secondary ruler 3. At this time, the secondary ruler 3 is rotated and the secondary ruler 3 is pressed against the limit block 403, which can ensure that the secondary ruler 3 is in a vertical state, which can effectively improve the accuracy of observation.

[0025] like Figure 3 As shown, a fixing assembly installed on one side of the resin damping hinge 1 fixes the limit block 403 in the vertical state. The fixing assembly includes a notch 5 provided on the mounting plate 4, the sphere 401 is located in the notch 5, a rotating rod 501 is rotatably installed on the mounting plate 4, the rotating rod 501 penetrates the mounting plate 4 and extends to both sides of the mounting plate 4, the center of the rotating rod 501 is located in the notch 5, a left-handed thread 502 is provided on one side of the rotating rod 501, and a right-handed thread 503 is provided on the other side of the rotating rod 501, a first nut 504 is fixedly installed on one side of the mounting plate 4, and a second nut 505 is fixedly installed on the other side of the mounting plate 4, the first nut 504 is threadedly connected to the left-handed thread 502, and the second nut 505 is threadedly connected to the right-handed thread 503, and a handle 506 is provided on both sides of the rotating rod 501. The mounting plate 4 is made of elastic metal material. The handle 506 is rotated forward to drive the rotating rod 501 to rotate, and the rotating rotating rod 501 will push the first nut 504 and the second nut 505 away from each other, which will drive the notch 5 to expand. At this time, the notch 5 will not press the ball 401, and the ball 401 will be able to rotate freely on the mounting plate 4. When the telescopic rod 402 rotates to a vertical state, the handle 506 is rotated backward to make the first nut 504 and the second nut 505 approach each other, so that the notch 5 squeezes and fixes the ball 401. At this time, the ball 401 cannot rotate, and the telescopic rod 402 is fixed, so that the limit block 403 is fixed.

[0026] Working principle: The rotating handle 506 can be rotated forward to drive the rotating rod 501 to rotate. The rotating rotating rod 501 will push the first nut 504 and the second nut 505 away from each other, and the notch 5 will be expanded. At this time, the notch 5 will not press the ball 401, and the ball 401 will be able to rotate freely on the mounting plate 4. The main ruler 2 is placed flat on the drawing board. At this time, the ball 401 is driven to rotate under the action of the counterweight 404. The telescopic rod 402 can be rotated to a vertical state. Then the rotating handle 506 is rotated in the opposite direction to make the first nut 504 and the second nut 505 approach each other, so that the notch 5 squeezes and fixes the ball 401, and the ball 401 cannot rotate. At this time, the telescopic rod 402 is stretched to drive the limit block 403 to rise, so that the limit block 403 can contact the secondary ruler 3. By rotating the secondary ruler 3 so that the secondary ruler 3 abuts against the limit block 403 , the secondary ruler 3 can be ensured to be in a vertical state, which can effectively improve the accuracy of observation and is simple and quick to operate.
