Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment:

[0032] As Figures 1 - 5 shown, the present invention provides a portable mine measuring device, including an outer shell 1, an inner disc 2, a measuring rope 13, a counterweight 6 and a detachable rocker 9. The specific features of each component are as follows:

[0033] Among them, the outer shell 1 is composed of a front part and a rear part. Specifically, a hole for installing the inner disc is provided in the center of the front, and six front grooves 3 are arranged outside the hole for clamping the rocker 9; a hole for installing the inner disc is provided in the center of the rear, and a rear groove 8 is provided outside the hole for receiving the counterweight 6, and a wristband 5 is fixed on the rear.

[0034] Among them, the inner disc 2 is arranged inside the outer shell 1. The inner disc 2 includes two curved discs 10, a central axis 12, a front small bearing 2 and a rear small bearing 7. A central axis cross groove 4 is provided at one end of the central axis 12 for clamping the rocker 9.

[0035] The measuring rope 13 provided in this embodiment is wound between the two curved discs 10, and the measuring rope 13 is retracted and released by rotating the central axis 12; the surface of the measuring rope 13 is marked with scales, and the end is connected to a measuring rope hook 11 for hanging the counterweight 6.

[0036] In this embodiment, the counterweight 6 is made of a metal material, is trapezoidal, and has a small hole at the top, which can be hung on the measuring rope hook 11 and is placed in the rear groove 8 during storage.

[0037] In this embodiment, the detachable rocker 9 is composed of a small cross member 91, a large cross member 92 and a rocker arm 93;

[0038] Specifically, the small cross member 91 can be inserted into the central axis cross groove 4 to drive the inner disc to retract the measuring rope 13;

[0039] The rocker arm 93 of the large cross member 92 can be bent and inserted into the front groove 3 of the housing to fix the length of the measuring rope 13.
