The base 22 is used to drive the clamping plates 21 and the mounting plate 3 to move up and down by lifting and lowering, thereby realizing the position adjustment of the test piece in the vertical direction.

[0053] Optionally, the limiting member 4 may be a limiting screw, one end of which is screwed into the side surfaces of the two clamping plates 21 along the second direction and abuts against the outer peripheral surface of the mounting plate 3 .

[0057] The slide groove 212 is provided so that the mounting plate 3 can slide in the corresponding slide groove 212; specifically, the sliding surface 2121 at the top of the slide groove 212 is tangent to the top of the mounting plate 3 to achieve the vertical limit of the mounting plate 3; the connecting surfaces 2122 on both sides of the slide groove 212 are arc-shaped, which can facilitate the mounting plate 3 to be uniformly stressed when the mounting plate 3 slides to the end. Optionally, the sliding surface 2121 is made of wear-resistant material.

[0058] Specifically, each clamping plate 21 is provided with a semicircular limiting screw hole 213 on both sides along the second direction, and after the two clamping plates 21 are connected, the two semicircular limiting screw holes 213 form a complete limiting screw hole 213, and the limiting member 4 is screwed into the corresponding limiting screw hole 213.

[0059] See also Figure 1 or Figure 3 In some possible embodiments, the base 22 includes a support plate 221 and two groups of limiting ribs 222; the support plate 221 is placed at the bottom of the two groups of clamps 21 and is respectively clamped with the two groups of clamps 21; the two groups of limiting ribs 222 are respectively abutted against the two sides of the clamps 21 along the second direction, and are connected to the clamps 21 through the limiting members 4; the two groups of limiting ribs 222 are fixedly connected to the top of the support plate 221.

[0060] The support plate 221 is used to stably support the mounting plate 3 and the clamping plate 21. By setting the limiting ribs 222, on the one hand, the connection between the base 22 and the clamping plate 21 can be reinforced to improve the supporting strength of the base 22; on the other hand, it is convenient to set the limiting screw hole 213 and pass the limiting member 4.

[0061] By symmetrically arranging the two groups of limiting ribs 222 , the base 22 is subjected to symmetrical forces, thereby ensuring the support stability of the mounting plate 3 and the clamping plate 21 .

[0062] See also Figure 4 and Figure 5 In some embodiments, a slot 214 extending upward is provided at the bottom of each clamp plate 21 , and two clamping blocks 2211 are provided on the support plate 221 at intervals along the first direction, and the two clamping blocks 2211 are correspondingly clamped in the two slots 214 .

[0063] By setting a clamping block and a clamping slot 214, the bottom of the clamping plate 21 can be clamped on the corresponding support plate 221; and through the connection between the clamping block and the clamping slot 214, the detachable connection between the support plate 221 and the clamping plate 21 is conveniently realized, thereby improving the installation efficiency of the installation disk 3.

[0066] As a specific embodiment of the above-mentioned T-slot, the two limiting portions 2142 of the T-slot are symmetrically arranged relative to the connecting portion 2141 along the second direction; it should be understood that the mounting disk 3 can slide along the second direction in the clamping plate 21. Therefore, when the mounting disk 3 slides, according to the interaction of forces, the two clamping plates 21 will produce a certain degree of shaking. In this application, an elastic member 23 is arranged to clamp the clamping plate 21 in the second direction, thereby reducing the shaking of the clamping plate 21 to a certain extent, avoiding the influence of the shaking of the clamping plate 21 on the test piece on the mounting disk 3, and thus improving the precision and accuracy of the test.

[0067] See also Figure 5 In some embodiments, one end of the elastic member 23 that abuts against the clamping block 2211 is connected to a tensioning rope 24, and one end of the tensioning rope 24 extends from the limiting portion 2142; wherein, when the tensioning rope 24 is pulled, the elastic member 23 is in a compressed state.

[0068] It should be understood that when the snap-in block 2211 is not installed, the elastic member 23 is in a relaxed state. Therefore, the end of the elastic member 23 will extend into the connecting portion 2141, affecting the installation of the snap-in block 2211. In the present application, by providing a tensioning rope 24, the tensioning rope 24 can be pulled before the snap-in block 2211 is installed, thereby making the elastic member 23 give way to the snap-in block 2211, thereby ensuring that the installation of the snap-in block 2211 is smooth.

[0069] It should be noted that the test auxiliary equipment for the large-space infrared measurement device further includes a support frame 5 , on which the infrared generator 1 and the test socket 2 are both mounted.

When the transmission screw 51 is rotated, the test seat 2 moves up and down along the transmission screw 51 to form the freedom of the base 22 to move up and down.

[0072] The transmission screw 51 is provided so that when the transmission screw 51 is rotated, the base 22 moves up and down along the axial direction of the transmission screw 51, thereby driving the mounting plate 3 and the test piece to move up and down, so that the test piece is aligned and focused on the infrared light path.

[0073] See also Figure 1 In some embodiments, a first bevel gear 52 is fixed on the transmission screw 51 , and a second bevel gear 53 is meshed on the first bevel gear 52 ; the second bevel gear 53 is arranged parallel to the mounting plate 3 and is placed on a side of the mounting plate 3 away from the infrared generator 1 .

[0074] The first bevel gear 52 and the second bevel gear 53 are provided so that when the second bevel gear 53 is rotated, the first bevel gear 52 is driven to rotate, thereby realizing the rotation of the transmission screw 51 .

[0076] By providing the rotating part 54, the first bevel gear 52 and the second bevel gear 53, it is convenient to rotate the rotating part 54 outside the support frame 5, and the transmission screw 51 is driven to rotate through the transmission of the first bevel gear 52 and the second bevel gear 53, thereby realizing the lifting and lowering of the base 22 and the mounting plate 3.
