[0001] This utility model relates to the technical field of platform scale testing equipment, and in particular to a high and low temperature platform scale testing equipment. Background Technology

[0002] High and low temperature platform scale testing equipment is mainly used in industries and scenarios that require weighing operations in extreme temperature environments, such as food processing, pharmaceuticals, chemicals, and aerospace. These environments demand not only high precision but also stable operation of the equipment across a wide temperature range.

[0003] Temperature variations can affect the performance of weighing sensors, including their sensitivity, linearity, and zero drift. Testing equipment often needs to test platform scales of different sizes. Existing testing equipment typically requires clamps to hold platform scales of varying sizes, which is cumbersome and makes it difficult to keep the platform scale on a stable plane, affecting testing accuracy. Therefore, a high and low temperature platform scale testing device is proposed. Utility Model Content

[0004] The main purpose of this utility model is to provide a high and low temperature platform scale testing device, which solves the problem that the existing testing equipment often needs to test platform scales of different sizes. The existing testing equipment often requires fixing platform scales of different sizes with clamps, which is cumbersome to operate. Furthermore, fixing with clamps makes it inconvenient to keep the platform scale on a stable plane, thus affecting the testing accuracy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high and low temperature platform scale testing device includes a testing equipment box. An installation base is fixedly connected inside the testing equipment box. Several first installation sleeves are fixedly connected at equal intervals above the installation base. A second installation sleeve is fixedly connected in the middle of the installation base. A second sealing block is movably sleeved inside the second installation sleeve. Four installation grooves are equidistantly opened on the outer side of the second sealing block.

[0006] Furthermore, four fixed bases are equidistantly arranged on the mounting base, and a fixing groove is opened above each of the four fixed bases. The four fixing grooves are respectively placed in four first mounting sleeves. A number of first sealing blocks are equidistantly arranged inside the testing equipment box. The number of first sealing blocks are respectively arranged in the number of first mounting sleeves and the four mounting grooves.

[0007] Furthermore, the testing equipment box is equipped with a platform scale assembly, which includes four platform scale sensors. The four platform scale sensors are respectively snapped into four fixed slots. The platform scale body is fixedly connected above the four platform scale sensors, and the platform scale tray is fixedly connected above the platform scale body.

[0008] Furthermore, four fixing bolts are equidistantly threaded above the platform scale tray, and a second sealing plate is threaded onto the four fixing bolts. The lower part of the second sealing plate abuts against the platform scale tray, and an insulation layer is fixedly connected above the second sealing plate. A first sealing plate is fixedly connected above the insulation layer, and the first sealing plate is threaded onto the four fixing bolts.

[0009] Furthermore, an insulation groove is provided inside the outer wall of the testing equipment box, a wiring hole is provided on one side of the testing equipment box, an air inlet pipe is fixedly connected to the other side of the testing equipment box, and an air outlet pipe is fixedly connected to the outer side of the testing equipment box.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through its fixed base, facilitates the installation of platform scales of different sizes for testing. It also allows for easy placement of the platform scale on a stable surface, improving testing accuracy. The platform scale sensor is snapped into the fixed slot. Depending on the size of the platform scale, the position of the fixed base where the sensor is snapped into the fixed slot varies. The fixed base is placed in the first mounting sleeve or mounting slot, and the platform scale must be placed in the center of the testing equipment box. By swapping the positions of the first sealing block and the fixed base as needed, the platform scale can be easily placed in the center of the testing equipment box. This design facilitates the installation of platform scales of different sizes for testing, ensuring a stable surface and improving testing accuracy.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-8 As shown, a high and low temperature platform scale testing device includes a testing equipment box 1. An installation base 18 is fixedly connected inside the testing equipment box 1. Several first installation sleeves 16 are fixedly connected at equal intervals above the installation base 18. A second installation sleeve 21 is fixedly connected in the middle of the installation base 18. A second sealing block 19 is movably sleeved inside the second installation sleeve 21. Four installation slots 20 are equidistantly opened on the outer side of the second sealing block 19. By adopting the above technical solution, the space formed by the first installation sleeves 16 and the installation slots 20 and the second installation sleeve 21 has the same size. Items of the same size can be placed in the space formed by the first installation sleeves 16 and the space formed by the installation slots 20 and the second installation sleeve 21. The bottom space of the first mounting sleeve 16 is hollowed out, and the bottom space of the second mounting sleeve 21 is also hollowed out. The size of the second sealing block 19 is designed so that the second sealing block 19 can be inserted into the second mounting sleeve 21 from above and then snapped into the second mounting sleeve 21. The second sealing block 19 and the mounting base 18 are filled with thermal insulation foam, which can enhance the thermal insulation function. The filling range of the thermal insulation foam is designed so as not to affect the placement of items in the first mounting sleeve 16 and the mounting groove 20. Several first mounting sleeves 16 are arranged symmetrically on the mounting base 18, and four are arranged in a group, with the four first mounting sleeves 16 in each group arranged symmetrically. The testing equipment box 1 is made of high-strength steel.

[0023] Four fixed bases 12 are equidistantly arranged on the mounting base 18. Each of the four fixed bases 12 has a fixing groove 13 on its top. The four fixing grooves 13 are respectively placed in the four first mounting sleeves 16. A number of first sealing blocks 17 are equidistantly arranged in the testing equipment box 1. The number of first sealing blocks 17 are respectively placed in the number of first mounting sleeves 16 and the four mounting grooves 20. By adopting the above technical solution, the number of fixed bases 12 and the number of first sealing blocks 17 respectively fill the space formed by the number of first mounting sleeves 16, the mounting grooves 20 and the second mounting sleeves 21. The first sealing block 17 is filled with insulating foam, which can enhance the insulation function; Four fixed bases 12 are respectively set on four centrally symmetrical first mounting sleeves 16.

[0024] The testing equipment box 1 contains a platform scale assembly, which includes four platform scale sensors 14. The four platform scale sensors 14 are respectively snapped into four fixing slots 13. The platform scale body 11 is fixedly connected above the four platform scale sensors 14. The platform scale tray 10 is fixedly connected above the platform scale body 11. By adopting the above technical solution, the platform scale assembly is the platform scale to be tested. In actual use, the positions of the fixed base 12 and the first sealing block 17 can be interchanged so that the fixed slots 13 of different sizes of platform scales can be snapped into the corresponding fixed slots 13.

[0025] Four fixing bolts 7 are equidistantly threaded on the upper part of the platform scale tray 10. A second sealing plate 9 is threaded on the four fixing bolts 7, and the lower part of the second sealing plate 9 abuts against the platform scale tray 10. An insulation layer 8 is fixedly connected above the second sealing plate 9, and a first sealing plate 6 is fixedly connected above the insulation layer 8. The first sealing plate 6 is threaded on the four fixing bolts 7. By adopting the above technical solution, the insulation layer 8 is made of insulation foam material, which can effectively keep the heat. The first sealing plate 6 and the second sealing plate 9 have several threaded holes at equal intervals, and the insulation layer 8 has connecting holes at the corresponding positions of the threaded holes. The fixing bolts 7 are threaded through the threaded holes on the first sealing plate 6 and the second sealing plate 9. By fixing the fixing bolts 7 through the threaded holes at different positions, platform scales of different sizes can be connected below the second sealing plate 9.

[0026] The outer wall of the testing equipment box 1 is provided with an insulation groove 2. A wiring hole 3 is provided on one side of the testing equipment box 1. An air inlet pipe 4 is fixedly connected to the other side of the testing equipment box 1. An air outlet pipe 5 is fixedly connected to the outer side of the testing equipment box 1. By adopting the above technical solution, the insulation groove 2 is filled with insulation foam to enhance the insulation function. The external temperature control device connected to the air inlet pipe 4 can supply cold or hot air to the detection equipment box 1 as needed. The external connection of the air outlet pipe 5 is an air extraction device, which can exhaust the air in the detection equipment box 1 and realize air circulation; Temperature detection equipment is installed inside the detection equipment box 1, which can monitor the temperature inside the detection equipment box 1 in real time. The wiring of the platform scale used for detection in the detection equipment box 1 can be connected to the outside through the wiring hole 3. Inside the testing equipment box 1, ventilation fans are installed near the air inlet pipe 4 and the air outlet pipe 5 to enhance air circulation.

[0027] It should be noted that during use, the testing equipment should be placed on a stable horizontal plane. The external temperature control device is connected through the air inlet pipe 4, and the external air extraction device is connected through the air outlet pipe 5. The testing equipment box 1 and the mounting base 18 are placed on the plane. The platform scale sensor 14 is snapped into the fixing groove 13. Depending on the size of the platform scale, the position of the fixing base 12 that the platform scale sensor 14 is snapped into through the fixing groove 13 is different. The fixing base 12 is placed in the first mounting sleeve 16 or the mounting groove 20. The platform scale must be placed in the middle position of the testing equipment box 1. The positions of the first sealing block 17 and the fixing base 12 can be interchanged as needed to facilitate placing the platform scale in the middle position of the testing equipment box 1. The first sealing plate 6, the insulation layer 8 and the second sealing plate 9 are fixedly connected above the platform scale tray 10 by fixing bolts 7. The fixed base 12 abuts against a stable external horizontal plane.

[0028] When the platform scale components are installed and testing is conducted, cold or hot air is injected into the testing equipment box 1 through the air inlet pipe 4 and the temperature regulation device. The cold or hot air changes the temperature inside the testing equipment box 1. At the same time, the external air extraction device of the air outlet pipe 5 is activated to exhaust the air, forming an air circulation until the temperature inside the testing equipment box 1 changes to the required temperature. Testing weights are placed on the first sealing plate 6, and the impact of temperature change on the testing accuracy of the platform scale is determined through the test results.
