Abstract
The utility model relates to a strainometer installation rod used for testing ground stress through a hollow inclusion manner. The strainometer installation rod used for testing the ground stress through the hollow inclusion manner comprises a rod body, a male head and a female head, and is characterized in that two ends of the rod body are provided with the male head and the female head, the interior of the male head and the interior of the female head are hollow and communicated with the rod body, the male head is composed of a hexagonal male head, a rubber blanket, pins and a cylindrical male head, the female head is composed of a hexagonal female head, a snap ring, a spring and a spring sliding rod, the outer diameter of the hexagonal male head is matched with the inner diameter of the hexagonal female head, the snap ring is installed on the periphery of the hexagonal female head, the spring is installed inside the snap ring, two clamping openings are symmetrically formed in the snap ring along the radial direction, under the effect of clamping force of the spring, the clamping openings can be tightly connected with the two pins of the cylindrical male head in a clamping mode, and the rubber blanket has a water leakage resistant function. The strainometer installation rod used for testing the ground stress through the hollow inclusion manner is simple in structure, convenient to use, practical, capable of being rapidly jointed in a split mode and disassembled and good in sealing.
Description
Technical field
The utility model relates to a kind of mounting rod, relates in particular to a kind of resistance strain gauge mounting rod for hollow inclusion method test crustal stress.
Background technique
At present, in the crustal stress test, hollow inclusion method commonly used need to be used the resistance strain gauge mounting rod, and mounting rod commonly used is Al-alloy pipe, and every pole is grown 1 to 2 meter and do not waited, and adopts solid screwed connection between bar and bar.The effect of mounting rod is to clean boring and resistance strain gauge is installed, all need to rotate mounting rod when cleaning boring and resistance strain gauge being installed, therefore at every turn connect and must screw bolt during dismounting, waste time and energy, greatly reduce the installation efficiency of hollow inclusion resistance strain gauge, because knock-off joint is solid screw, can not makes water enter boring by mounting rod, thereby can not realize washing the purpose of boring simultaneously.
Summary of the invention
Connect the deficiency of the inefficiency that wastes time and energy in order to overcome existing hollow inclusion resistance strain gauge mounting rod, the utility model provides a kind of hollow inclusion resistance strain gauge mounting rod, and this mounting rod connects easy, time saving and energy saving, can realize the efficient installation of resistance strain gauge.
The utility model is achieved by the following technical solution:
a kind of resistance strain gauge mounting rod for hollow inclusion method test crustal stress comprises the body of rod, male and female, it is characterized in that: there are a male and female in every mounting rod body of rod two ends, male and female inside are hollow, with body of rod UNICOM, wherein male is by the hexagonal male, rubber pad, pin and cylinder male form, female is by the hexagonal female, snap ring, spring and spring slide bar form, hexagonal male external diameter and hexagonal female internal diameter are complementary, the hexagonal female is peripherally equipped with snap ring, spring is housed in snap ring, snap ring radially is arranged with two bayonet sockets, bayonet socket can be tight with two pin clampings of cylinder male under the clamping force effect of spring, rubber paves the preventing water leakage effect.
The beneficial effects of the utility model are: this resistance strain gauge mounting rod, and simple in structure, convenient and practical, can splice fast dismounting, body of rod inside is hollow UNICOM simultaneously, the direct injection hole of water can have been reduced wash number when cleaning boring, has improved installation efficiency.

Fig. 4 is the snap ring detail drawing.
In figure, the 1. body of rod, 2. male, 3. female, 21. hexagonal males, 22. rubber pads, 23. pins, 24. cylinder males, 31. hexagonal females, 32. snap rings, 33. springs, the yellow slide bars of 34. bullets, 35. snap rings
Embodiment
As follows by reference to the accompanying drawings: a kind of resistance strain gauge mounting rod for hollow inclusion method test crustal stress comprises the body of rod 1, male 2 and female 3.The described body of rod 1 is hollow high-strength aluminum pipe, male 2 and female 3 and the body of rod 1 welding and boring UNICOM, male 2 is comprised of hexagonal male 21, rubber pad 22, pin 23 and cylinder male 24, female 3 is comprised of hexagonal female 31, snap ring 32, spring 33 and spring slide bar 34, snap ring 32 radial symmetric are arranged two bayonet sockets 35, and hexagonal male 21 external diameters and hexagonal female 31 internal diameters are complementary.
In the embodiment shown in the figures, described hexagonal male 21 is inserted in hexagonal female 31, rubber pad 22 plays the preventing water leakage effect, the pin 23 of afterwards bayonet socket 35 of snap ring 32 being aimed on cylinder male 24 inserts, snap ring 32 turns clockwise when pin 23 arrives the corner of bayonet socket 35, pin 23 is entered in the turning of bayonet socket 35, complete connection work under the effect of spring clamping power.The mounting rod that connects has good airproof performance, and the advantages such as rotation difficult drop-off have characteristics convenient to disassembly simultaneously.
Claims (2)
1. one kind is used for the resistance strain gauge mounting rod that the hollow inclusion method is tested crustal stress, comprise the body of rod, male and female, it is characterized in that: respectively there are a male and female in body of rod two ends, male and female inside are hollow, with body of rod UNICOM, male is comprised of hexagonal male, rubber pad, pin and cylinder male, and female is comprised of hexagonal female, snap ring, spring and spring slide bar, and hexagonal male external diameter and hexagonal female internal diameter are complementary.
2. mounting rod according to claim 1, it is characterized in that: the hexagonal female is peripherally equipped with snap ring, and spring is housed in snap ring, and snap ring radially is arranged with two bayonet sockets, the pin clamping of bayonet socket and cylinder male.
