Technical Field

[0001] The utility model relates to the technical field of testing machines, in particular to a constant temperature and humidity testing machine. Background Art

[0002] A constant temperature and humidity testing machine is a device used to simulate environments under different temperature and humidity conditions. It is usually used to test and evaluate the performance and stability of materials under various environmental conditions. This testing machine usually includes a temperature control system and a humidity control system, which can accurately control the temperature and humidity in the testing machine and adjust them as needed.

[0003] The above-mentioned and prior arts have the following defects: when using a testing machine to test materials, the tester needs to observe the changes on the material surface through the observation window on the surface of the testing machine and record them. However, since the position of the observation window is fixed and it is difficult to move the material without opening the test box, it is not convenient for the tester to accurately grasp the changes on the material surface.

[0004] Therefore, a constant temperature and humidity testing machine is proposed. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a constant temperature and humidity testing machine, including a testing box, a plurality of electric heating rods are installed on the bottom inner wall of the testing box, a nozzle is installed on the top inner wall of the testing box, a temperature sensor is fixedly connected to the inner wall of the testing box, a humidity sensor is fixedly connected to the inner wall of the testing box, an observation window is installed on the upper surface of the testing box, and a rotating structure is provided on the inner wall of the testing box, the rotating structure includes a fixed plate, the fixed plate is fixedly connected to the testing box, a sliding frame is slidably connected to the surface of the fixed plate, a rotating frame is rotatably connected to the surface of the sliding frame, a bidirectional lead screw is rotatably connected to the rotating frame, the arc surface of the bidirectional lead screw is threadedly connected to two clamping plates, the clamping plate is slidably connected to the inner wall of the rotating frame, a hand wheel is rotatably connected to the testing box, one end of the hand wheel is fixedly connected to an electromagnet, the rotating frame is made of iron, and the electromagnet passes through the sliding frame and abuts against the surface of the rotating frame.

[0007] The effect achieved by the above components is: by setting up a rotating structure, when testing the material, the material can be rotated without opening the test chamber, which is convenient for the tester to comprehensively view the material and thus more accurately grasp the changes of the material during the test process.

[0008] Preferably, two rubber strips are fixedly connected to the surface of the clamping plate.

[0009] The effect achieved by the above components is that the rubber strip can prevent the clamping plate and the block material from being worn due to rigid contact.

[0010] Preferably, a bolt is connected to the inner thread of the clamping plate, one end of the bolt is rotatably connected to a pressure plate, and the pressure plate is slidably connected to the clamping plate.

[0011] The effect achieved by the above components is: when it is necessary to test the strip or sheet material, one end of the strip or sheet material is placed in the pressure plate, and then the bolt is turned. The bolt will drive the pressure plate to move with the help of the thread. When the pressure plate presses the strip or sheet material against the inner wall of the clamp, the strip or sheet material can be fixed, thereby expanding the application scope of the test chamber.

[0012] Preferably, the arc surface of the hand wheel is provided with a protective cover.

[0013] The effect achieved by the above components is that the protective cover can improve the comfort of the tester when turning the hand wheel.

[0016] Preferably, a stopper is fixedly connected to one end of the round rod, and the diameter of the stopper is larger than the diameter of the round rod.

[0017] The effect achieved by the above components is that since the diameter of the stopper is larger than the diameter of the round rod, the limit plate will not slide off the circular arc surface of the round rod when the limit plate slides along the circular arc surface of the round rod.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, by setting a rotating structure, when testing a material, the material can be rotated without opening the test box, so that the tester can have a comprehensive view of the material and more accurately grasp the changes of the material during the test.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0028] like Figure 1-5As shown, the utility model provides a constant temperature and humidity test machine, including a test box 1, a plurality of electric heating rods 2 are installed on the bottom inner wall of the test box 1, a nozzle 3 is installed on the top inner wall of the test box 1, a temperature sensor 4 is fixedly connected to the inner wall of the test box 1, a humidity sensor 5 is fixedly connected to the inner wall of the test box 1, an observation window 7 is installed on the upper surface of the test box 1, and a rotating structure 6 is provided on the inner wall of the test box 1. The rotating structure 6 includes a fixing plate 601, which is fixedly connected to the test box 1, and the fixing plate 601 is fixedly connected to the test box 1. 1 is slidably connected to the surface of a sliding frame 602, and the surface of the sliding frame 602 is rotatably connected to a rotating frame 603. A bidirectional lead screw 604 is rotatably connected inside the rotating frame 603. The arc surface of the bidirectional lead screw 604 is threadedly connected to two clamping plates 605. The clamping plates 605 are slidably connected to the inner wall of the rotating frame 603. A handwheel 606 is rotatably connected inside the test box 1, and one end of the handwheel 606 is fixedly connected to an electromagnet 607. The rotating frame 603 is made of iron, and the electromagnet 607 passes through the sliding frame 602 and abuts against the surface of the rotating frame 603.

[0029] like Figure 2-Figure 5 As shown, two rubber strips 608 are fixedly connected to the surface of the clamping plate 605. The rubber strips 608 can prevent the clamping plate 605 from being worn due to rigid contact with the block material. The clamping plate 605 is internally threaded with a bolt 609. One end of the bolt 609 is rotatably connected to a pressure plate 610. The pressure plate 610 is slidably connected to the clamping plate 605. When it is necessary to test the strip or sheet material, one end of the strip or sheet material is placed in the pressure plate 610, and then the bolt 609 is rotated. The bolt 609 will drive the pressure plate 610 to move with the help of the thread. When the pressure plate 610 presses the strip or sheet material against the inner wall of the clamping plate 605, the strip or sheet material can be fixed, thereby expanding the scope of application of the test box 1.

[0030] like Figure 2-Figure 5 As shown, the arc surface of the hand wheel 606 is provided with a protective cover 611, and the protective cover 611 can improve the comfort of the tester when turning the hand wheel 606. The inner wall of the rotating frame 603 is fixedly connected with two round rods 612, and the arc surface of the round rod 612 is slidably connected with a limiting plate 613. The surface of the rotating frame 603 is provided with a limiting hole 614, and the size of the limiting plate 613 is adapted to the size of the limiting hole 614. The limiting plate 613 is inserted into the limiting hole 614, and the limiting hole 614 reaches The position of the limit plate 613 is limited, thereby limiting the position of the splint 605 to prevent the splint 605 from shaking during the subsequent placement of materials and affecting the operation. A stopper 615 is fixedly connected to one end of the round rod 612, and the diameter of the stopper 615 is larger than the diameter of the round rod 612. Since the diameter of the stopper 615 is larger than the diameter of the round rod 612, the limit plate 613 will not slide off the arc surface of the round rod 612 during the process of the limit plate 613 sliding along the arc surface of the round rod 612.

[0031] The overall working principle is that when testing the material, the sliding frame 602 is pulled, and when the sliding frame 602 slides along the surface of the fixed plate 601, it will drive the rotating frame 603 to move, and the movement of the rotating frame 603 will drive the clamping plate 605 to move. After the clamping plate 605 is moved out of the test box 1, the limiting plate 613 is slid along the arc surface of the round rod 612, so that the limiting plate 613 is inserted into the limiting hole 614, and the limiting hole 614 reaches the position of limiting the limiting plate 613, thereby limiting the position of the clamping plate 605 to prevent the clamping plate 605 from shaking during the subsequent placement of the material and affecting the operation. Since the diameter of the stopper 615 is larger than the diameter of the round rod 612, When the positioning plate 613 slides along the arc surface of the round rod 612, the limiting plate 613 will not slide off the arc surface of the round rod 612. When a block material needs to be tested, the block material is placed between the two clamping plates 605, and then the bidirectional lead screw 604 is rotated. The bidirectional lead screw 604 will drive the two clamping plates 605 to move towards each other by means of threads. The two clamping plates 605 will clamp and fix the block material. The rubber strip 608 can prevent the clamping plates 605 from being worn due to rigid contact with the block material. When a strip or sheet material needs to be tested, one end of the strip or sheet material is placed in the pressure plate 610. , and then turn the bolt 609, the bolt 609 will drive the pressure plate 610 to move with the help of the thread, when the pressure plate 610 presses the strip or sheet material against the inner wall of the clamping plate 605, the strip or sheet material can be fixed, thereby expanding the application range of the test box 1, and then the limiting plate 613 is pulled out from the inner wall of the limiting hole 614, and then the sliding frame 602 is pushed into the test box 1 along the surface of the fixing plate 601. After closing the test box 1, the temperature in the test box 1 can be controlled by the electric heating rod 2, and the humidity in the test box 1 can be changed by the nozzle 3, so that the test box 1 can test the material under a constant temperature and humidity environment, and the temperature sensor 4 and humidity sensor 5 can facilitate the test personnel to grasp the changes of temperature and humidity in the test box 1 in real time. When checking the changes of the material surface through the observation window 7, power is supplied to the electromagnet 607, and the electromagnet 607 will attract the rotating frame 603. When the hand wheel 606 rotates, the electromagnet 607 will drive the rotating frame 603 to rotate synchronously. The rotation of the rotating frame 603 will rotate the material, so that the material can be rotated without opening the test box 1, which is convenient for the test personnel to comprehensively check the material and more accurately grasp the changes of the material during the test process. The protective cover 611 can improve the comfort of the test personnel when turning the hand wheel 606.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
