DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0031] Reference Figures 1 to 6As shown, a HTRB high temperature and high pressure testing equipment comprises a testing chamber 1, four supporting legs 11 are fixedly installed at the bottom of the testing chamber 1, and two second grooves 21 are provided in the inner cavity of the testing chamber 1; a clamping mechanism is also included for clamping the product to be tested; the clamping mechanism comprises two first sliders 22, the two first sliders 22 are slidably installed on the bottom wall of the inner cavity of the testing chamber 1, the top of the first slider 22 is fixedly connected with a supporting plate 23, the top of the supporting plate 23 is slidably connected with a slide plate 2314, one side of the slide plate 2314 is fixedly connected with four first springs 2313 and a first telescopic rod 2312, one side of the slide plate 2314 is slidably installed with three slide bars 254, a plurality of friction blocks 2453 are movably installed on the top of the supporting plate 23, a plurality of heating rods 31 are fixedly installed on the top wall of the inner cavity of the testing chamber 1, connecting columns 43 are slidably installed at both ends of the testing chamber 1, and a pressure detector 442 is fixedly connected to one end of the connecting column 43.

[0032] During production, when quality inspection of products is carried out in a high temperature and high pressure environment, due to the physical characteristics of thermal expansion and contraction, when the cables are positioned, the cables themselves are easily expanded and stretched due to heat, making the cables as a whole loose and difficult to fix, which affects the inspection and measurement process.

[0033] When the present invention is in use, the product to be tested is first placed in the inner cavity of the test chamber 1, and the two ends of the product are fixed by bringing the three sliding bars 254 on the same side closer to each other. The first telescopic rod 2312 and the first spring 2313 cooperate to enable the sliding bar 254 to always exert a pulling force on the product. When the product is heated, even if the product expands and contracts due to thermal expansion and contraction, the product can be kept in a stretched state by pulling the first spring 2313 and the first telescopic rod 2312. The inner cavity of the test chamber 1 is heated by a plurality of heating rods 31, and the friction blocks 2453 on both sides of the product can detect the state of the product in a high temperature environment. The product can be squeezed by two pressure detectors 442 to detect the state of the product in a high pressure environment. Since the pressure detector 442 can display the pressure provided on the product, the staff can clearly see the data changes of the product as the pressure increases.

[0034] Further, such as Figure 1 As shown, a first groove 12 is opened on the top of the test chamber 1, a sealing plate 13 is slidably installed on the inner surface of the first groove 12, a rack 14 is fixedly installed on the top of the sealing plate 13, the rack 14 is meshed with a first gear 15, and a first motor 16 is fixedly connected to one side of the first gear 15, and the first motor 16 is fixedly installed on the top of the test chamber 1.

[0035] When the present invention is in use, since it is necessary to detect data changes of the product under high temperature conditions, the product needs to be in a sealed state to make it more convenient for the staff to heat the product. When in use, the first motor 16 outputs the first gear 15 to rotate, and the first gear 15 is meshed with the rack 14. Further, the first gear 15 can drive the rack 14 to move, and the sealing plate 13 can move with the rack 14 on the inner surface of the first groove 12, thereby further achieving the purpose of sealing the test chamber 1.

[0036] Further, such as Figure 2 and Figure 3 As shown, a first thread groove 221 is provided on one side of the first slider 22, a bidirectional threaded rod 222 is rotatably installed on the inner surface of the second groove 21, one end of the bidirectional threaded rod 222 passes through the second groove 21 and is fixedly connected to a first pulley 223, the two first pulleys 223 are driven by a first belt 224, a second motor 225 is fixedly connected to one side of the first pulley 223, a first support frame 226 is fixedly connected to one side of the test chamber 1;

[0037] The top of the support plate 23 is provided with a fourth groove 232 and a third groove 231, and two second sliders 2315 are fixedly installed at the bottom of the slide plate 2314, and the two second sliders 2315 are slidably installed on the inner surface of the fourth groove 232 respectively;

[0038] Two vertical plates 2311 are fixedly installed on the top of the support plate 23, wherein two ends of the first telescopic rods 2312 and the first spring 2313 are respectively fixedly connected to the opposite surfaces of the vertical plates 2311 and the slide plate 2314, and the other two first springs 2313 and the first telescopic rods 2312 are respectively fixedly installed on the inner surface of the third groove 231;

[0039] A ninth groove 25 is provided on one side of the slide plate 2314, and a gear ring 251 and a second gear 256 are rotatably installed on the inner surface of the ninth groove 25. The gear ring 251 and the second gear 256 are meshed with each other, and three limiting grooves 252 are provided on one side of the gear ring 251, and a first limiting block 253 is slidably installed on the inner surface of the limiting groove 252, and the first limiting block 253 is fixedly installed on one side of the slide bar 254, and three limiting rings 255 are fixedly installed on one side of the slide plate 2314, and the slide bar 254 is slidably installed on the inner surface of the limiting ring 255, and a clip 2541 is fixedly installed on one side of 254, and a third motor 257 is fixedly connected to one side of the second gear 256, and the third motor 257 is fixedly installed on one side of the slide plate 2314.

[0040] When the present invention is in use, firstly, the output shaft of the second motor 225 drives the first pulley 223 to rotate, and the first belt 224 drives the two first pulleys 223 to respectively drive the two bidirectional threaded rods 222 to rotate, so that the two first sliders 22 can move toward or away from each other. After the two first sliders 22 are adjusted to a suitable position, the product to be tested is placed on the inner ring of the gear ring 251, and then the output shaft of the third motor 257 drives the second gear 256 to rotate. The second gear 256 meshes with the gear ring 251, and further drives the gear ring 251 to rotate. At this time, the first limit block 253 will slide on the inner surface of the limit groove 252. The limiting groove 252 further moves with the slide bar 254. Since the limiting ring 255 has a limit on the slide bar 254, the three slide bars 254 will be close to each other under the limit of the limiting ring 255, and then clamp the product. Since the product will be in a high temperature environment during the product inspection process, in order to avoid the product becoming loose due to the change in product length caused by thermal expansion and contraction, thereby making the instruction data of the product inaccurate, the first telescopic rod 2312 and the first spring 2313 always generate tension on the product. Even if the length of the product changes, the product will not become loose, thereby ensuring the accuracy of product data detection.

[0041] Further, such as Figure 4 As shown, a support block 24 is fixedly installed on the top of the support plate 23, and a fifth groove 241 is opened on one side of the support block 24, and a slide 242 is slidably installed on the inner surface of the fifth groove 241, and a sixth groove 243 is opened on one side of the slide 242, and two clamping rods 244 are rotatably installed on the inner surface of the sixth groove 243, and a seventh groove 2441 is opened on one side of the clamping rod 244, and a second telescopic rod 2442 is rotatably installed on the inner surface of the seventh groove 2441, and a second spring 2443 is wound and installed on the inner surface of the second telescopic rod 2442, and a clamping plate 245 is fixedly connected to one end of the clamping rod 244, and a plurality of eighth grooves 2451 are opened on one side of the clamping plate 245, and a third spring 2452 is fixedly installed in the inner cavity of the eighth groove 2451, and the friction block 2453 is fixedly connected to one end of the friction block 2453, and the friction block 2453 is slidably installed on the inner surface of the eighth groove 2451.

[0042] When the present invention is in use, the friction block 2453 contacts the two ends of the product. When in use, by pressing one end of the clamping rod 244, the second telescopic rod 2442 and the second spring 2443 are contracted, thereby increasing the distance between the two clamping plates 245, so that the staff can place the two ends of the product between the two clamping plates 245. At this time, the second telescopic rod 2442 and the second spring 2443 are extended, and the two clamping plates 245 clamp the product. During this process, the friction block 2453 in contact with the product will slide on the inner surface of the eighth groove 2451, thereby contracting the third spring 2452. This is beneficial to increase the contact area with the product, and further can increase the accuracy of product data detection.

[0043] Further, such as Figure 5 As shown, two second pulleys 33 are rotatably installed on the top of the test chamber 1, and the two second pulleys 33 are driven by a second belt 34. A fourth motor 37 is fixedly connected to the top of one of the second pulleys 33, and a second support frame 38 is fixedly connected to the top of the fourth motor 37. The second support frame 38 is fixedly installed on the top of the test chamber 1. A connecting shaft 35 is fixedly connected to the bottom of the second pulley 33. The connecting shaft 35 passes through the top wall of the test chamber 1 and is fixedly connected to the fan blades 36. A plurality of connecting rods 3 are fixedly connected to the top wall of the inner cavity of the test chamber 1. The plurality of connecting rods 3 are grouped in pairs, and two connecting rods 3 in the same group are respectively fixedly installed on both sides of the heating rod 31. A plurality of protective frames 32 are fixedly installed on the top wall of the inner cavity of the test chamber 1.

[0044] When the present invention is in use, the inner cavity of the test chamber 1 is heated by the heating rod 31. In order to make the temperature of the inner cavity of the test chamber 1 more uniform, the second pulley 33 is rotated by the output shaft of the fourth motor 37. The two second pulleys 33 are driven by the second belt 34 to respectively drive the two connecting shafts 35 to rotate. The two connecting shafts 35 respectively drive the two fan blades 36 to rotate, thereby accelerating the air flow in the inner cavity of the test chamber 1 and making the heat distribution in the inner cavity of the test chamber 1 more uniform. The heating rod 31 can be separated by the protective frame 32 to prevent the staff from accidentally touching the heating rod 31 and causing injuries.

[0045] Further, such as Figure 6 As shown, the top and bottom of the test chamber 1 are rotatably installed with a rotating block 4, the outer surface of the rotating block 4 is wound with a third belt 45, the top of the rotating block 4 is provided with a second thread groove 41, the inner surface of the second thread groove 41 is threadedly connected with a screw rod 42, the bottom of the screw rod 42 passes through the top wall of the test chamber 1 and is fixedly connected with a connecting column 43, the outer surface of the connecting column 43 is provided with two tenth grooves 431, the inner surface of the tenth groove 431 is slidably installed with a second limit block 443, and the second limit block 443 is fixedly installed on the inner wall of the test chamber 1;

[0046] A mounting block 44 is fixedly installed at the bottom of the connecting column 43, and a mounting groove 441 is opened at the bottom of the mounting block 44. The pressure detector 442 is fixedly installed on the inner surface of the mounting groove 441. A mounting frame 462 is fixedly connected to one side of the test chamber 1, and a transmission rod 463 is rotatably installed on the inner surface of the mounting frame 462. The two third belts 45 are both wound and installed on the outer surface of the transmission rod 463. The top of the transmission rod 463 is fixedly connected to the fifth motor 46, and the top of the fifth motor 46 is fixedly connected to the third support frame 461, and the third support frame 461 is fixedly installed on the top of the test chamber 1.

[0047] When the present invention is in use, the transmission rod 463 is rotated by the output shaft of the fifth motor 46, and the two rotating blocks 4 also start to rotate after being transmitted by the two third belts 45. As the rotating blocks 4 rotate, due to the restriction of the second limit block 443, the screw rod 42 will move under the restriction of the connecting column 43, so that the two pressure detectors 442 can approach each other and squeeze the product, thereby detecting the quality of the product under high temperature and high pressure conditions.

[0048] Working principle: First, the output shaft of the second motor 225 drives the first pulley 223 to rotate, and after the transmission of the first belt 224, the two first pulleys 223 drive the two bidirectional threaded rods 222 to rotate respectively, so that the two first sliders 22 can adjust their positions according to the length of the product. When the two ends of the product are respectively in the inner rings of the two gear rings 251, the output shaft of the third motor 257 drives the second gear 256 to rotate, and the gear ring 251 can be rotated by the engagement of the second gear 256 with the gear ring 251. When the gear ring 251 rotates, the first limit block 253 slides on the inner surface of the limit groove 252 , and the first limit block 253 slides with the slide bar 254 under the restriction of the limit ring 255, and the three slide bars 254 on the same side approach each other, and finally the three clamps 2541 contact the outer surface of the product and clamp the product, and the cooperation of the first springs 2313 and the first telescopic rod 2312 on the same side can make the two slide plates 2314 tend to move away from each other, so that when the product expands due to heat, it can move with the product, so that the product is always in a stretched state, and the second telescopic rod 2442 and the second spring 2443 can make the two clamps 245 approach each other, so that the friction block 2453 can be in close contact with the product.

[0049] The inner cavity of the test chamber 1 can be heated by the heating rod 31, and the output shaft of the fourth motor 37 drives the second pulley 33 to rotate, and the second belt 34 drives the two second pulleys 33 to rotate respectively, and the two connecting shafts 35 further drive the fan blades 36 to rotate, which can speed up the air flow in the inner cavity of the test chamber 1, thereby making the temperature of the inner cavity of the test chamber 1 more uniform;

[0050] The transmission rod 463 is rotated by the output shaft of the fifth motor 46, and after being transmitted by the two third belts 45, the two rotating blocks 4 also start to rotate. Under the restriction of the second limit block 443, the screw rod 42 and the connecting column 43 start to move in the vertical direction. By bringing the two mounting blocks 44 close to each other and allowing the two pressure detectors 442 to clamp the product, the quality changes of the product under high pressure can be detected.

[0051] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
