Description

Technical Field

[0001] This utility model relates to the field of testing tool technology, specifically a haze meter sample holder. Background Technology

[0002] The sample holder for a haze meter is a specialized device used to fix the sample to be tested and ensure that it is in complete contact with the surface of the haze meter's measuring aperture. Its design directly affects the accuracy and stability of the test and is the foundation for the haze meter to achieve high-precision and high-efficiency measurement.

[0003] Chinese patent CN205950569U discloses a sample holder for a haze meter, comprising a base plate and a turntable. The base plate has test holes and screw mounting holes. The turntable includes a central rotating shaft and multiple circular holes of different diameters. The center of each circular hole and the center of the test hole are located on the same circumference of a circle centered on the rotating shaft. This invention modifies the circular holes of the turntable for testing haze meters to be variable, with a diameter ranging from 10-50 mm, making it widely applicable to flat samples, bulbs, and elongated samples.

[0004] The aforementioned fixture has a variable rotary hole, but the existing fixture and haze meter are fixedly installed, which limits the range of motion of the sample on the haze meter. At the same time, for samples of different sizes, it is necessary to solve the problem of sample clamping and free movement in order to detect more parts of the sample. Therefore, a haze meter sample fixture is needed. Utility Model Content

[0005] The purpose of this invention is to provide a sample holder for a haze meter to solve the problems of low flexibility and limited detectable parts of the sample in existing holders.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a haze meter sample holder, comprising a base pad and four clamping pads, wherein a moving mechanism is provided on the base pad; the moving mechanism comprises a horizontal slide seat and a vertical slide seat, the horizontal slide seat being slidably mounted on the base pad, two No. 1 bolts being threadedly mounted in parallel on the upper side of the base pad, and two No. 2 bolts being slidably mounted in parallel on the vertical slide seat, wherein a fixing bracket is threadedly mounted on the two No. 2 bolts.

[0007] Preferably, the horizontal slide block is perpendicular to the vertical slide block, and the horizontal slide block is clamped and slidably mounted between the base pad and the two No. 1 bolts.

[0008] Preferably, the vertical sliding seat is clamped and slidably installed between the two No. 2 bolts and the fixing frame, and rubber pads are fixedly installed on both the No. 1 bolt and the No. 2 bolt.

[0009] Preferably, a thin plate is provided protruding from one end of the base pad, and several triangular plates are installed between the horizontal slide and the vertical slide.

[0010] Preferably, a fixing mechanism is provided between the fixing frame and the four clamping pads. The fixing mechanism includes two sliding rods, which are fixedly installed side by side on one side of the fixing frame. Two mounting seats are slidably installed side by side on the two sliding rods. A No. 3 bolt is threaded on one side of each of the two mounting seats, and a bidirectional bolt is rotatably installed in the middle of the mounting seat. Two support rods are threaded side by side on the bidirectional bolt.

[0011] Preferably, the fixing bracket is clamped and slidably installed between the mounting base and the No. 3 bolt, and a rubber pad is fixedly installed on the No. 3 bolt.

[0012] Preferably, the clamping pad is fixedly connected to the support rod, and the two support rods are at the same distance from the center of the bidirectional bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The sample clamp of the haze meter can move the horizontal slide and the fixed frame relative to the bottom pad and the vertical slide respectively by controlling the first bolt and the second bolt. In this way, the fixed frame can move freely on the same plane under the action of the first bolt and the second bolt, which can provide a base for the sample to move freely. The clamp is supported by the bottom pad, which greatly improves the flexibility of the clamp.

[0014] 2) The sample clamp of this haze meter controls the fixed connection between the clamping pads and the support rods. The distance between the two support rods and the middle of the bidirectional bolts is the same. When in use, the distance between the two No. 3 bolts and the two mounting seats is changed, and the distance between the bidirectional bolts and the two support rods is changed, so that the four clamping pads can be adapted to the sample, improving the speed and stability of clamping.

[0017] Example 1 Combination Figures 1-4 A haze meter sample holder includes a base pad 1 and four clamping pads 2. A moving mechanism 3 is provided on the base pad 1. The moving mechanism 3 includes a horizontal slide 301 and a vertical slide 302. The horizontal slide 301 is slidably mounted on the base pad 1. Two No. 1 bolts 303 are threadedly mounted side by side on the upper side of the base pad 1. Two No. 2 bolts 304 are slidably mounted side by side on the vertical slide 302. The two No. 2 bolts 304 are threadedly mounted with fixing brackets 305.

[0018] The horizontal slide block 301 is perpendicular to the vertical slide block 302, and is clamped and slidably mounted between the base pad 1 and two No. 1 bolts 303. By controlling the two No. 1 bolts 303, the horizontal slide block 301 can be moved and fixed on the base pad 1. The vertical slide block 302 is clamped and slidably mounted between two No. 2 bolts 304 and the fixing bracket 305. By controlling the No. 2 bolts 304, the fixing bracket 305 can be moved and fixed on the vertical slide block 302. Rubber pads are fixedly mounted on both the No. 1 bolts 303 and the No. 2 bolts 304. The rubber pad can increase the friction between bolt 303 and bolt 304 and the horizontal slide 301 and vertical slide 302 respectively, so that the fixing frame 305 can move freely on the same plane under the action of bolt 303 and bolt 304. A thin plate is provided at one end of the bottom pad 1. Several triangular plates are installed between the horizontal slide 301 and the vertical slide 302. The thin plate and triangular plates are used to improve the stability of the fixture.

[0019] Example 2 See Figure 5A fixing mechanism 4 is provided between the fixing frame 305 and the four clamping pads 2. The fixing mechanism 4 includes two slide rods 401, which are fixedly installed side by side on one side of the fixing frame 305. Two mounting seats 402 are slidably installed side by side on the two slide rods 401. A No. 3 bolt 403 is threaded on one side of each mounting seat 402, and a double bolt 404 is rotatably installed in the middle of the mounting seat 402. Two support rods 405 are threaded side by side on the double bolt 404.

[0020] The fixing bracket 305 is clamped and slidably installed between the mounting base 402 and the No. 3 bolt 403. A rubber pad is fixedly installed on the No. 3 bolt 403 to increase the clearance between the No. 3 bolt 403 and the fixing bracket. The friction force of 305, the clamping pad 2 is fixedly connected to the support rod 405, and the two support rods 405 are at a distance from the bidirectional bolt. The distance between the middle parts of 404 is consistent. When in use, the distance between the two No. 3 bolts 403 and the two mounting seats 402 is changed by controlling the distance between the two bidirectional bolts 404 and the two support rods 405, so that the four clamping pads 2 can be adapted to the sample.

[0021] In actual operation, by controlling bolt 303 and bolt 304, the horizontal slide 301 and the fixed frame 305 move relative to the bottom pad 1 and the vertical slide 302 respectively. Thus, the fixed frame 305 can move freely on the same plane under the action of bolt 303 and bolt 304, which can provide a freely movable base for the sample. The fixture is supported by the bottom pad 1, which greatly improves the flexibility of the fixture. The control clamp 2 is fixedly connected to the support rod 405. The two support rods 405 are at the same distance from the middle of the bidirectional bolt 404. In use, the distance between the two No. 3 bolts 403 and the two mounting seats 402 is changed, and the distance between the bidirectional bolt 404 and the two support rods 405 is changed, so that the four clamps 2 can be adapted to the sample.
