Description

Technical Field

[0001] This utility model relates to the field of placement rack technology, specifically a placement rack for a bottom-suction rotary temperature and humidity meter. Background Technology

[0002] A temperature and humidity testing chamber is a device specifically designed to test the accuracy of temperature and humidity meters. It creates a constant temperature and humidity environment, and then places both a standard temperature and humidity meter and the meter to be tested inside. If the reading on the meter to be tested differs significantly from the reading on the standard meter, the meter is considered unqualified and cannot be used as a standard instrument for environmental testing.

[0003] Currently, there are rotating racks for suspending temperature and humidity meters inside temperature and humidity testing chambers. However, in actual use, the meters are suspended one by one. When a large number of meters are concentrated on one side of the rack, they may tilt or overturn due to imbalance, resulting in low stability during use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bottom-suction rotary temperature and humidity meter holder. The holder can be firmly attached and fixed inside the temperature and humidity testing box by suction cup feet. Even if a large number of temperature and humidity meters to be tested are hung on one side of the holder, they will not tilt or overturn due to loss of balance. This is more in line with the requirement of hanging temperature and humidity meters to be tested in sequence, and its stability during application is better.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:

[0006] A mounting rack for a bottom-suction rotary temperature and humidity meter is provided. The mounting rack is used inside a temperature and humidity testing chamber to suspend the temperature and humidity meter to be tested. It includes multiple annular rotating frames arranged vertically. A central sleeve is fixed to the annular rotating frame by multiple spokes arranged in a circumferential array. The central sleeve is rotatably mounted on a central shaft. The bottom end of the central shaft is connected to an annular support structure by multiple linear reinforcing structures arranged in a circumferential array. The bottom of the annular support structure is fixedly connected to multiple suction cup feet arranged in a circumferential array.

[0007] Using the above solution, the mounting rack can be firmly attached and fixed inside the temperature and humidity detection box by suction cup feet. Even if a large number of temperature and humidity meters to be tested are hung together on one side of the mounting rack, it will not tilt or overturn due to loss of balance. This is more in line with the requirement of hanging temperature and humidity meters to be tested in sequence, and its stability during application is better.

[0008] In a preferred embodiment of a mounting bracket for a bottom-suction rotary temperature and humidity meter, both the linear reinforcing structure and the annular support structure are hollow air tubes, and the linear reinforcing structure and the annular support structure are interconnected; the interior of the suction cup foot is connected to the interior of the annular support structure; a suction handle capable of moving along its length is sealed and installed inside the linear reinforcing structure; the suction handle is an L-shaped bend, located in a clearance groove on the side wall of the linear reinforcing structure; a sealing sleeve is bonded and fixed to the surface of the suction handle, and the suction handle is press-fitted to the inner wall of the linear reinforcing structure through the sealing sleeve; multiple corrugated grooves are arranged in an array along its axial direction on the outer wall of the sealing sleeve.

[0009] To further improve the reliability of the suction cup feet adsorbing the bottom plate of the temperature and humidity detection chamber, the above solution can be adopted. Pulling the air extraction handle will cause the sealing sleeve to move, thereby putting the linear reinforcement structure, the ring support structure and the suction cup feet into a negative pressure state, which can further improve the adsorption effect of the suction cup feet.

[0010] In a preferred embodiment of a mounting bracket for a bottom-suction rotary temperature and humidity meter, multiple sets of circumferentially arrayed limiting protrusions are welded and fixed to the upper surface of the annular rotary bracket. Each set of limiting protrusions includes two protrusions, and the two protrusions are spaced apart from each other.

[0011] To avoid affecting the detection error due to left-right contact between adjacent temperature and humidity meters, the above scheme is adopted. The temperature and humidity meters to be measured are suspended between the two protrusions of each set of limiting protrusions. At this time, the temperature and humidity meters to be measured between adjacent ones will not contact each other left-right and will be evenly distributed, which can maximize the accuracy of the measured structure.

[0012] In a preferred embodiment of a mounting bracket for a bottom-suction rotary temperature and humidity meter, the diameter of all the annular rotating brackets gradually decreases from bottom to top.

[0013] To avoid the temperature and humidity meters to be measured from touching each other and affecting the detection error, the diameter of the annular rotating frame on each layer will be different. The temperature and humidity meters to be measured are suspended between the two protrusions of each set of limiting protrusions. At this time, the temperature and humidity meters to be measured on adjacent locations will not touch each other and will be evenly distributed, which can maximize the accuracy of the measured structure.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. The mounting rack can be firmly attached and fixed inside the temperature and humidity detection box by suction cup feet. Even if a large number of temperature and humidity meters to be tested are hung on one side of the mounting rack, it will not tilt or tip over due to loss of balance. It is more in line with the need to hang temperature and humidity meters to be tested in sequence, and its stability during application is better.

[0016] 2. In order to further improve the reliability of the suction cup feet adsorbing the bottom plate of the temperature and humidity detection box, the suction handle can be pulled out. When the suction handle moves, it will drive the sealing sleeve to move, so that the linear reinforcement structure, the ring support structure and the suction cup feet are in a negative pressure state, which can further improve the adsorption effect of the suction cup feet.

[0017] 3. To avoid the measurement error caused by the left and right contact between two adjacent temperature and humidity meters, the temperature and humidity meters to be measured are suspended between the two protrusions of each set of limit protrusions. At this time, the temperature and humidity meters to be measured between two adjacent ones will not contact each other and will be evenly distributed, which can maximize the accuracy of the measured structure.

[0018] 4. To avoid the temperature and humidity meters to be measured from touching each other and affecting the detection error, the diameter of the ring rotating frame on each layer will be different. The temperature and humidity meters to be measured are suspended between the two protrusions of each set of limiting protrusions. At this time, the temperature and humidity meters to be measured on adjacent locations will not touch each other and will be evenly distributed, which can maximize the accuracy of the measured structure.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 5 As shown, a bottom-suction rotary temperature and humidity meter holder is used inside a temperature and humidity testing chamber 12 to suspend the temperature and humidity meters to be tested. It includes two vertically arranged annular rotating frames 1. Each annular rotating frame 1 is fixed to a central sleeve 3 by multiple circumferentially arrayed spokes 2. The central sleeve 3 is rotatably mounted on a central shaft 4. The bottom end of the central shaft 4 is connected to an annular support structure 6 by multiple circumferentially arrayed linear reinforcing structures 5. The bottom of the annular support structure 6 is fixedly connected to multiple circumferentially arrayed suction cup feet 7. This holder can be firmly attached and fixed inside the temperature and humidity testing chamber 12 by the suction cup feet 7. Even if a large number of temperature and humidity meters to be tested are concentrated and suspended on one side of the holder, it will not tilt or overturn due to loss of balance. This better meets the requirements for sequentially suspending temperature and humidity meters to be tested, and its stability during application is better.

[0032] like Figures 6 to 8As shown, both the linear reinforcing structure 5 and the annular support structure 6 are hollow air tubes, and they are interconnected. The interior of the suction cup foot 7 is connected to the interior of the annular support structure 6. A suction handle 8 that can move along its length is sealed inside the linear reinforcing structure 5. The suction handle 8 is an L-shaped bend and is located in a relief groove 9 on the side wall of the linear reinforcing structure 5. A sealing sleeve 10 is bonded and fixed to the surface of the suction handle 8, and the suction handle 8 is press-fitted to the inner wall of the linear reinforcing structure 5 through the sealing sleeve 10. The outer wall of the sealing sleeve 10 has multiple corrugated grooves arranged in an array along its axial direction. To further improve the reliability of the suction cup foot 7 in adsorbing the bottom plate of the temperature and humidity detection box 12, the suction handle 8 can be pulled out. When the suction handle 8 moves, it will drive the sealing sleeve 10 to move, thereby putting the linear reinforcing structure 5, the annular support structure 6, and the suction cup foot 7 into a negative pressure state, which can further improve the adsorption effect of the suction cup foot 7.

[0033] like Figure 4 As shown, the upper surface of the annular rotating frame 1 is welded with multiple sets of circumferentially arrayed limiting protrusions. Each set of limiting protrusions includes two protrusions 11, which are spaced apart from each other. To avoid the temperature and humidity meters to be measured from touching each other and affecting the detection error, the temperature and humidity meters to be measured are suspended between the two protrusions 11 of each set of limiting protrusions. At this time, the temperature and humidity meters to be measured will not touch each other and will be evenly distributed, which can maximize the accuracy of the measured structure.

[0034] like Figures 2 to 3 As shown, the diameter of all the annular rotating frames 1 gradually decreases from bottom to top. In order to avoid the temperature and humidity meters to be measured from touching each other and affecting the detection error, the diameter of the annular rotating frames 1 of each layer will be different. The temperature and humidity meters to be measured are suspended between the two protrusions 11 of each set of limiting protrusions. At this time, the temperature and humidity meters to be measured at adjacent locations will not touch each other and will be evenly distributed, which can maximize the accuracy of the measured structure.

[0035] The working principle of this utility model:

[0036] Before application, place the holder inside the temperature and humidity detection chamber 12, and press the suction cup feet 7 to firmly attach and fix them inside the temperature and humidity detection chamber 12. Figure 5 As shown; to further improve the reliability of the suction cup foot 7 adsorbing the bottom plate of the temperature and humidity detection box 12, the suction handle 8 can be pulled out. When the suction handle 8 moves, it will drive the sealing sleeve 10 to move, thereby putting the linear reinforcing structure 5, the ring support structure 6 and the suction cup foot 7 into a negative pressure state, such as Figure 9 As shown, this further enhances the adsorption effect of the suction cup feet 7.

[0037] In application, the temperature and humidity meter to be tested and the standard temperature and humidity meter are both suspended between the two protrusions 11 of each set of limiting protrusions. At this time, the temperature and humidity meters to be tested in adjacent locations will not contact each other and will be evenly distributed, which can maximize the accuracy of the measured structure. By rotating the ring rotating frame 1 while suspending the temperature and humidity meters, even if a large number of temperature and humidity meters to be tested are concentrated on one side of the placement frame, there will be no tilting or overturning due to loss of balance. This is more in line with the requirement of suspending the temperature and humidity meters to be tested in sequence, and its stability during application will be better.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
