Problems solved by technology

[0003] However, at present, endoscopes mostly use hoses, which is inconvenient to adjust the direction of the lens. It is not convenient to adjust the lens on the hard rod, but the length of the hard rod is short for easy carrying, and the use is limited. The length of the hard rod is lengthened, which makes it inconvenient to carry.

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, a telescopic rod for an endoscope includes an overcoat rod 1, an inner telescopic rod and an elastic plunger; one end of the inner telescopic rod is movably installed in the outer rod 1, and the other end is positioned outside the outer rod 1; The outer casing rod 1 is a round rod with a hollow inside, and an anti-skid sleeve 11 is arranged on the outer surface of the outer casing rod 1, and an elastic plunger and a shaft sleeve 12 are installed at one end of the outer casing rod 1; the inner telescopic rod is a round rod with a hollow interior. , the outer circular surface of the inner telescopic rod is provided with a two-way threaded chute 52, the two-way threaded chute 52 is provided with a positioning groove 51, and the positioning groove 51 is a straight groove, that is, the two sides of the positioning groove 51 are mutually Parallel planes, the positioning groove 51 is parallel to the end face of the inner telescopic rod, ...

Embodiment 2

[0030] On the basis of Embodiment 1, there are two sliders 6 on the inner telescopic tube, which are symmetrically installed in the two-way threaded chute 52, and there are also two shaft sleeves 12 matched with the slider 6, which are symmetrically distributed. At one end of the jacket rod 1.

[0031]Two slide blocks 6 are adopted to improve the stability when the inner telescopic rod stretches out.

Embodiment 3

[0033] On the basis of Embodiments 1 and 2, there are two semicircular grooves at each end of the inner telescopic tube, which are symmetrically distributed on the outer circular surface of the inner telescopic tube, and two elastic plungers are also provided, which are symmetrically distributed on the outer circular surface of the inner telescopic tube. Outer rod 1 one end.

[0034] Two elastic plungers are used to improve the stability of the limit and further prevent free rotation.

Abstract

The invention relates to a telescoping rod for an endoscope, and the telescoping rod comprises an external sleeve rod, an internal telescoping rod, and an elastic plunger. One end of the internal telescoping rod is movably installed in the external sleeve rod, and the other end of the internal telescoping rod is located at an outer side of the external sleeve rod. The external sleeve rod is a circular rod with the hollow interior, and the external circular surface of the external sleeve rod is provided with an antiskid sleeve. One end of the external sleeve rod is provided with the elastic plunger and a shaft sleeve. The internal telescoping rod is a circular rod with the hollow interior, and the external circular surface of the internal telescoping rod is provided with a bidirectional threaded chute which is provided with a positioning groove. The other end of the internal telescoping rod is provided with antiskid stripes, and the external circular surface is provided with a semi-circular groove. A sliding block is movably installed in the bidirectional threaded chute, and comprises an arc-shaped guide block and a rotating shaft, wherein the arc-shaped guide block is located in the bidirectional threaded chute. The rotating shaft of the sliding block is movably installed in the shaft sleeve. The telescoping rod provided by the invention is portable, is light in weight, is convenient for stretching and drawing, has the adjustable length, is long in stretching length, is simple in operation, is large in load, and is wide in application range.

Description

technical field [0001] The invention relates to a telescopic rod, especially a rod for endoscope. Background technique [0002] Industrial endoscopes and police endoscopes are a branch of non-destructive testing and security anti-terrorism, and can also be said to be a specialized detection technology. Due to its special size design, the endoscope allows us to observe the internal surface structure or working state of the object easily and accurately without destroying the surface of the object to be detected. Non-destructive testing and security anti-terrorism require the use of endoscopes as testing tools, which are professionally designed and produced to meet complex usage environments. Endoscope inspection is a detection technology that has been widely used in recent years with the development of endoscope manufacturing technology. Endoscopes can be used for inspection and observation of high temperature, poisonous, nuclear radiation and places that cannot be directly ...
