Description

Technical Field

[0001] This application relates to the field of rangefinders, and more specifically, to a novel hand-pushed roller rangefinder. Background Technology

[0002] A push-type roller rangefinder is a tool for measuring distances. It typically consists of a rod and a measuring roller. It can measure ground distances, indoor lengths, areas, and volumes, and features easy operation, a wide measurement range, high speed, and high accuracy.

[0003] Under normal circumstances, the handheld lever of a push-type roller rangefinder is an integrated unit. This integrated lever makes the push-type roller rangefinder unsuitable for measuring personnel of different heights, and its operation is inconvenient. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a novel hand-push roller rangefinder comprising: a rangefinder roller, a telescopic control structure, and a gripping structure; the telescopic control structure is used to move the gripping structure closer to and further away from the rangefinder roller; the rangefinder roller is rotatably connected to the telescopic control structure; and a measuring structure for detecting the number of rotations of the rangefinder roller is provided between the rangefinder roller and the telescopic control structure.

[0006] Furthermore, the telescopic control structure includes: a first insert and a second insert; the first insert and the second insert are slidably connected so that the first insert and the second insert move closer to each other or further away from each other; when the first insert and the second insert move further away from each other, the grip structure moves further away from the ranging roller; when the first insert and the second insert move closer to each other, the grip structure moves closer to the ranging roller.

[0007] Furthermore, both the first insertion rod and the second insertion rod are straight rods.

[0008] Furthermore, both the first and second inserts are bent rods.

[0009] Furthermore, both the first and second inserts are elastic rods; both the first and second inserts have straight and bent states.

[0010] Furthermore, a limiting structure is provided between the first insertion rod and the second insertion rod; the limiting structure is used to extend or fix the movable rod, allowing the user to adjust the length of the extended movable rod according to the environment and their height.

[0011] Furthermore, the limiting structure is a snap ring type spring buckle.

[0012] Furthermore, the limiting structure is a screw pair that fits tightly against the second insert rod.

[0013] Furthermore, a fixing foot is provided between the ranging roller and the telescopic control structure for fixing or relaxing the ranging roller; the fixing foot is connected to the rangefinder via a tension spring, so that the fixing foot can be folded up or relaxed; when the fixing foot is in the folded state, the bottom edge of the fixing foot contacts the ground and forms a stable structure with the ranging roller in a triangular cross-section to stabilize the ranging roller; when the fixing foot is in the relaxed state, the bottom edge of the fixing foot does not contact the ground, so that the ranging roller can move to measure distance.

[0014] The beneficial effect of this application is that, during the distance measurement process, the distance between the grip structure and the distance measuring roller can be adjusted by using the telescopic control component according to different environments, so as to better adapt to people of different heights for use.

[0038] Example 1

[0039] A novel hand-push roller rangefinder includes: a rangefinder roller 1, a telescopic control structure 2, and a gripping structure 3. The rangefinder roller 1 has a vertically downward measuring mechanism in the middle of its support. The gripping structure 3 is a rod that is easy to hold. The rangefinder roller 1 is rotatable relative to the telescopic control structure 2.

[0040] In some designs, the telescopic control structure 2 is a rod made of rubber or fiberglass. This embodiment uses fiberglass, which is easier to bend and has a self-recovering function. In actual use, the control structure 2 can be bent, thereby changing the distance between the grip structure 3 and the ranging roller 1. The ranging roller 1 is rotatably connected to the telescopic control structure 2.

[0041] In some schemes, the measuring structure is a counter used to count the number of rotations of the ranging roller 1, thereby obtaining the distance moved by the ranging roller based on the number of rotations of the ranging roller 1, and realizing the distance measuring function.

[0042] In other schemes regarding the measuring structure, the measuring structure can also be a positioning pin, with multiple graduations formed on the ranging roller. Finally, the position specified by the positioning pin is observed to determine the angle or number of rotations of the ranging roller, thereby achieving the function of distance measurement.

[0043] In other embodiments of the telescopic control structure 2, the telescopic control structure 2 is used to form a first insert 21 connected to the ranging roller 1 and a second insert 22 connected to the gripping structure 3. The first insert 21 is a hollow rod, and the second insert 22 is a solid rod. The first insert 21 is sleeved on the outer wall of the second insert 22, so that the first insert 21 can slide relative to the second insert 22. Thus, the first insert 21 and the second insert 22 cause the gripping structure 3 and the ranging roller 1 to move closer and further apart, adapting to the height of the measuring personnel and improving flexibility.

[0044] The specific solutions for the first insertion rod 21 and the second insertion rod 22 are as follows:

[0045] First, both the first insertion rod 21 and the second insertion rod 22 are rigid straight rods. Second, both the first insertion rod 21 and the second insertion rod 22 are curved rods with an arc-shaped outer contour, allowing the first insertion rod 21 and the second insertion rod 22 to move away from each other. Third, the first insertion rod 21 and the second insertion rod 22 are made of rubber or fiberglass for restoring their shape after bending.

[0046] In some designs, the grip structure 3 is detachably connected to the second insertion rod 22, and the ranging roller 1 is detachably connected to the first insertion rod 21, thus splitting the rangefinder into three parts for easy carrying and high dexterity.

[0047] Specifically, the first insertion rod 21 is connected to the ranging roller 1 via the directional cylinder 11 on the ranging roller 1. A fixed foot 12 is provided between the ranging roller and the telescopic control structure 2, and the fixed foot 12 is used to support the rangefinder.

[0048] Specifically, the grip structure 3 includes a base 31 and a handle 33. The handle 33 is designed for easy gripping by the user. The second insertion rod 22 is fixed to the base 31; more precisely, the base is fixed to the grip structure 3. A display screen and operation buttons are formed on the base 31. The display screen shows the distance measurement reading, allowing the reading to be displayed next to the user's hand for convenient reading and recording at the end of the measurement.

[0049] In some designs, the rangefinder also includes a limiting structure 4, which is located at the top of the first insertion rod 21. The limiting structure 4 is used to extend or fix the second insertion rod 22, allowing the user to adjust the extension length of the second insertion rod 22 according to the environment and their height. In one specific design, the limiting structure 4 is equipped with a rotatable elastic limiting piece 41, specifically a snap-ring type spring buckle. The elastic limiting piece 41 has an engaged state and a movable state. In the movable state, the elastic limiting piece 41 is not in contact with the second insertion rod 22, and the second insertion rod 22 slides relative to the first insertion rod 21, extending or retracting from the first insertion rod 21. In the engaged state, the elastic limiting piece 41 contacts the second insertion rod 22 and forms a limiting relationship, with the second insertion rod 22 stationary relative to the first insertion rod 21. Adjusting the extension height of the second insertion rod 22 is very convenient; simply flipping the elastic limiting piece 41 is sufficient.

[0050] Another specific design for the limiting mechanism 4 is as follows: the limiting structure 4 employs a spiral block 42 that is tightly attached to the second insert rod 22. Specifically, the spiral block 42 is a threaded column with a motor at its bottom driven by a rotating shaft. A housing is provided between the first insert rod 21 and the second insert rod 22 to accommodate the motor and the spiral block 42. The motor drives the spiral block 42 to rotate, causing it to press against the outer wall of the second insert rod 22. Thus, when the spiral block 42 rotates, it causes the second insert rod 22 to extend outward or retract inward within the first insert rod 21, thereby extending and shortening the telescopic control component. Electric adjustment allows for automatic extension and shortening of the telescopic control component, making it more convenient to use.

[0052] The distance measurement method of the distance measuring instrument in this application when the measuring structure uses a positioning pin is as follows:

[0053] 1. Wall-to-wall measurement method: Adjust the distance measurement mode to wall-to-wall mode using the button controller on handle 33, place the distance measuring roller 1 on the ground, let the rear wheel touch the wall behind, and move the distance measuring roller 1 in a straight line until it touches the wall in front. At this time, the data displayed on the display screen 32 is the distance moved plus the diameter of the distance measuring roller 1 (2R), which is the distance L between the walls.

[0054] 2. Wall-to-point measurement method: Adjust the ranging mode to wall-to-point mode using the button controller on handle 33, place the ranging wheel on the ground, let the rear wheel rest against the wall behind, and move the ranging roller 1 in a straight line until the point pointed to by the measuring structure coincides with the endpoint. At this time, the data displayed on the display screen 32 is the distance moved plus the radius (R) of the ranging roller 1, which is the distance L between the wall and the point. The point-to-wall measurement method is the same.

[0055] 3. Point-to-point measurement method: Adjust the ranging mode to point-to-point mode by using the button controller on handle 33, place the ranging roller 1 on the ground, make the measuring structure point coincide with the starting point, move the ranging roller 1 until the positioning pin point coincides with the ending point, and the data displayed on the display screen 32 is the point-to-point distance L.

[0056] 4. Step-type measurement method: Adjust the distance measurement mode to total mode using the button controller on handle 33. Place the distance measuring roller 1 on the ground, align the measuring structure's pointing point with the starting point, and move the distance measuring roller 1. When the distance measuring roller 1 touches the wall, press the counting button. The counted distance is the moving distance plus the radius R of the distance measuring roller 1. Then move the distance measuring roller 1 again. When the measuring structure coincides with the extension line of the step surface, press the counting button again. The counted distance is the moving distance plus the radius R of the distance measuring roller 1. Repeat the above operation until the distance measuring roller 1 reaches the designated position. At this point, the overall length L is the sum of the counts for odd-numbered measurements, the height H is the sum of the counts for even-numbered measurements, and the overall moving length is L + H.
