Description

Technical Field

[0001] The utility model relates to the technical field of outdoor exploration, in particular to a portable rope measuring device. Background Art

[0002] Field measurement is to measure the distance between two points far apart on the ground. First, a straight line must be determined between the two points, and then the distance between the two points is measured along the straight line using tools. In relatively open field areas, electronic equipment can be used for measurement due to fewer obstructions. However, in field areas with abundant trees, only measuring ropes can be used due to obstruction by trees. The measuring ropes need to be frequently retracted and released during use, which makes them inconvenient to use.

[0003] The existing patent (publication number: CN220334425U) discloses a portable measuring rope reel for outdoor exploration, including a measuring rope, a casing and a hand-held mechanism, the casing having a mounting through hole, the hand-held mechanism being arranged in the mounting through hole, the casing and the hand-held mechanism being rotatably connected; a accommodating space is arranged on the outer side of the casing, the accommodating space extending around the circumference of the mounting through hole; one end of the measuring rope is detachably connected to the outer side of the casing, and the measuring rope is used to be wound around the outer side of the casing along the extension direction of the accommodating space.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: the device reclaims the measuring rope by manually rotating the connecting handle, which is time-consuming and labor-intensive, and lacks a retaining structure for the measuring rope, making it inconvenient to limit the length of the measuring rope and not conducive to outdoor exploration. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a portable rope measuring device, which solves the problem that the prior device recovers the measuring rope by manually rotating the connecting handle, which is time-consuming and labor-intensive, and lacks a retaining structure for the measuring rope, making it inconvenient to limit the length of the measuring rope and not conducive to outdoor exploration.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a portable rope measuring device, comprising a round box, a rope outlet is provided on the side wall of the round box, a torsion spring is provided inside the round box, the torsion spring is connected to an annular plate, the annular plate is in sliding contact with the inner wall of the round box, the annular plate is connected to a survey rope, the upper wall of the round box is provided with a connecting plate and a cylindrical box, the upper end of the connecting plate is hinged with a connecting rod, a slot is provided in the connecting rod, a sliding rod is slidably installed in the slot, and the sliding rod is movably inserted in the upper wall of the cylindrical box.

[0007] Preferably, a snap plate is movably inserted into the upper wall of the rope outlet, the upper end of the snap plate is connected to a limit plate, a spring is connected between the limit plate and the upper wall of the cylindrical box, and the slide rod is in sliding contact with the spring.

[0008] Preferably, a hook is provided at the other end of the survey rope.

[0009] Preferably, a push plate is provided at one end of the slot.

[0010] Preferably, a circular plate is provided at the upper end of the sliding rod.

[0011] Beneficial Effects

[0012] The utility model provides a portable rope measuring device. The utility model is designed with a structure that can conveniently and quickly recover the rope, and can fix the extended length of the rope. The device is first held in the hand by an operator, and the thumb pushes up the push plate to drive the snap plate to move. The snap plate is released from contact with the survey rope, and the hook is recorded at a predetermined position, so that the survey rope can be stretched freely. When the survey rope is stretched, the torsion spring rotates with elasticity. After reaching a predetermined length, the control of the push plate can be released, and the snap plate is reset to fix the extended length of the survey rope. After the survey is completed, the push plate is pushed up to drive the snap plate to move. The torsion spring has a rebound force, and the survey rope is quickly recovered. The device is easy to use and easy to carry, suitable for field exploration, can fix the extended length of the rope, and can quickly recover the rope, reducing the manpower rope collection operation, and is highly practical.
