Description

Technical Field

[0001] The utility model relates to the technical field of protective pieces, in particular to a light guide pipe insertion protective piece. Background Art

[0002] As a device capable of emitting ideal radiation, a blackbody furnace's surface absorbs and radiates electromagnetic waves of all wavelengths, and the relationship between radiation intensity and temperature exhibits a strict Planck's law. This property makes it an ideal standard source for calibrating infrared equipment. Whether for temperature measurement, thermal imaging analysis, or spectral characteristic testing, a blackbody furnace can provide a stable, traceable, and accurate radiation reference, ensuring that infrared equipment calibration results meet the highest standards. A blackbody furnace typically consists of a heating cavity with a small hole inside that simulates the thermal radiation characteristics of an object. By absorbing all external radiation energy and radiating all of its own energy, it provides a stable and reliable heat reference source to help calibrate and calibrate various infrared measuring instruments.

[0003] In the prior art, when measuring the temperature of a blackbody furnace, a hollow quartz tube 153 mm long and 3.5 mm in diameter is placed inside a temperature measuring component composed of a solid quartz rod 182 mm long and 2 mm in diameter and some metal parts. The portion of the quartz tube that contacts the blackbody furnace is the 10 mm root portion, which is also the portion that contacts the metal parts where the blackbody furnace is inserted. Due to the lack of protective components, the tube can easily be accidentally touched by operators, causing breakage. A broken quartz tube inside the blackbody furnace is also difficult to remove, resulting in a technical problem of wasted working time. Utility Model Content

[0004] The utility model provides a light guide tube insertion protection piece, which solves the technical problem in the prior art that the light guide tube is easily accidentally touched by an operator, thereby causing material breakage, due to lack of protection components for the light guide tube.

[0005] In order to solve the above problems, the utility model provides a light guide tube insertion protective member, including a fixing seat, characterized in that: the fixing seat surface is symmetrically provided with mounting holes, the middle part is fixedly connected with an insertion tube, the end face of the insertion tube is provided with an insertion hole, the surface is provided with a thread, the connecting tube is rotatably connected to the insertion tube through the thread, and the end face is provided with an insertion limit hole, and the insertion limit hole and the insertion hole are on the same vertical line.

[0006] Furthermore, a group of mounting holes are symmetrically provided on the surface of the fixing seat.

[0007] Furthermore, the height of the thread is smaller than the height of the connecting tube.

[0008] Furthermore, the diameter of the insertion limiting hole is smaller than the diameter of the insertion hole.

[0009] Furthermore, the fixing seat, the insertion conduit and the connecting tube are all made of metal.

[0010] The beneficial effects of the present invention are as follows: the present application installs the fixing seat on the surface of the black body furnace through the installation hole, then inserts the light guide tube through the insertion tube into the black body furnace, and then passes the connecting tube through the light guide tube and is threadedly connected with the insertion tube. During the process of threaded connection between the connecting tube and the insertion tube, since the surface of the light guide tube itself is provided with a metal component and contacts the inner side of the connecting tube, the light guide tube can be slowly inserted into the black body furnace through the rotational connection between the connecting tube and the insertion tube, thereby achieving the technical effect of protecting the temperature measuring material.

[0014] In order to make the technical solution of the present invention more clear, the present invention will be further described below with reference to specific embodiments of the drawings.

[0015] like Figure 1-2 As shown, according to an embodiment of the present utility model, a light guide tube insertion protector includes a fixing base 1, a surface of which is symmetrically provided with mounting holes 11, a middle portion of which is fixedly connected with an insertion tube 2, an end surface of which is provided with an insertion hole 21, and a surface thereof is provided with a thread 22, a connecting tube 3 is rotatably connected to the insertion tube 2 through the thread 22, and an end surface thereof is provided with an insertion limit hole 31, and the insertion limit hole 31 and the insertion hole 21 are on the same vertical line.

[0016] Furthermore, a group of mounting holes 11 are symmetrically provided on the surface of the fixing base 1 . During operation, the fixing base 1 is mounted on the surface of the blackbody furnace through the mounting holes 11 .

[0017] Furthermore, the height of the thread 22 is smaller than the height of the connecting tube 3 .

[0018] Furthermore, the diameter of the insertion limit hole 31 is smaller than the diameter of the insertion hole 21. During operation, the light guide is passed through the insertion limit hole 31, and the metal parts provided on its surface are pushed to slowly insert into the black body furnace to prevent the light guide from being broken due to the insertion speed being too fast.

[0019] Furthermore, the fixing seat 1, the insertion conduit 2 and the connecting tube 3 are all made of metal.

[0020] Working principle: First, install the fixing base 1 on the surface of the blackbody furnace through the mounting hole 11, then insert the light guide tube into the insertion hole 21, and insert it into the blackbody furnace through the insertion tube 2. Then, the connecting tube 3 is threadedly rotated to connect with the insertion tube 2. When the connecting tube 3 and the insertion tube 2 contact each other, the insertion limit hole 31 provided on the connecting tube 3 passes through the light guide tube, and the surface of the end of the light guide tube itself is provided with a metal part, and the diameter is larger than the insertion limit hole 31. Therefore, in the process of threaded rotation connection between the connecting tube 3 and the insertion tube 2, the connecting tube 3 will push the light guide tube to slowly insert into the blackbody furnace.

[0021] The above embodiments can be combined with each other and further implemented if they are not mutually exclusive.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
