[0001] This utility model relates to the field of automated equipment and instruments, and in particular to an automatically retractable temperature measuring device. Background Technology
[0002] Temperature measuring devices are instruments and equipment used to measure the temperature of objects or the environment. Their core function is to sense temperature changes through sensors and convert the temperature signals into readable values or signals for monitoring, control, or analysis. The automatic retractable temperature measuring device for producing magnesium sulfate heptahydrate from magnesite flotation tailings is an intelligent device that adds an automatic extension mechanism to the traditional temperature measuring device, so that its temperature measuring probe can automatically extend to measure the temperature and automatically retract after completing the task. This design is mainly used to avoid the probe being exposed to harsh environments for a long time.
[0003] When using the temperature measuring device, staff will manually extend the temperature probe to the measuring location and use the probe to measure the temperature of the person or object that needs to be measured. After the measurement is completed, the temperature sensor wire will be manually rolled up and stored.
[0004] The existing technology has the following drawbacks: the temperature measuring probe of traditional temperature measuring devices is usually directly exposed, and it is easy to get dust and dirt when not in use. This not only affects the measurement accuracy, but also shortens the service life of the device. In addition, there is a lack of effective protection measures during storage and transportation, which reduces the practicality of the device. Therefore, an automatically retractable temperature measuring device is proposed to solve the above problems. Utility Model Content

[0012] As a further description of the above technical solution:
[0013] The inclined block is slidably connected to the inner wall of the storage box, and the insert block is slidably connected to the inner wall of the moving rod.
[0014] As a further description of the above technical solution:
[0015] The upper left side of the inclined block is set as an inclined surface, which is in contact with the bottom part of the slider.
[0016] As a further description of the above technical solution:

[0035] 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.
[0036] Reference Figures 1-3This utility model provides an embodiment of an automatically retractable temperature measuring device, including a storage box 1 with a display showing the test temperature. A hinged cover 2 is hinged to the inner wall of the storage box 1, and a slider 4 is hinged to the inner wall of the cover 2 via a hinge rod 3. Since the length of the hinge rod 3 is fixed, when the slider 4 moves downwards with one end of the hinge rod 3, the other end of the hinge rod 3 will cause the cover 2 to flip upwards; conversely, when the slider 4 moves upwards with one end of the hinge rod 3, the other end of the hinge rod 3 will cause the cover 2 to flip downwards. A wedge 8 is elastically connected to the left inner wall of the storage box 1 via a moving spring 9. When the wedge 8 moves to the left, the moving spring 9 is compressed; upon resetting, the spring 9 returns to its original position. The force causes the inclined block 8 to reset. The outer wall of the inclined block 8 is fixedly connected to the movable block 10. The inner wall of the movable block 10 contacts the temperature probe 11. The movable block 10 supports the temperature probe 11. The left end of the temperature probe 11 is fixedly connected to the temperature sensing wire 12. The inner wall of the storage box 1 is provided with a limit mechanism. The inner wall of the storage box 1 is provided with a storage component. The limit mechanism includes a moving rod 5. The moving rod 5 passes through and is slidably connected to the inner wall of the storage box 1. The storage box 1 has a slot corresponding to the moving rod 5, allowing the moving rod 5 to move vertically. The inner wall of the rear end of the moving rod 5 is elastically connected to the insert block 6 through the movable spring 7. When the insert block 6 moves backward, the movable spring 7 is compressed. When resetting, the elastic force of the movable spring 7 causes the insert block 6 to reset.
[0037] Reference Figure 2 and Figure 8 The storage component includes a rotating column 13, which is rotatably connected to the inner wall of the storage box 1. The storage box 1 has a slot corresponding to the rotating column 13 to facilitate the rotation of the rotating column 13. The outer wall of the rotating column 13 is elastically connected to the storage box 1 through a torsion spring 14. When the rotating column 13 rotates counterclockwise, the torsion spring 14 is compressed. When resetting, the elastic force of the torsion spring 14 is used to reset the rotating column 13.
[0038] Reference Figures 4-6 The outer wall of the temperature sensing line 12 is in contact with the inner wall of the movable block 10. The upper left side of the inclined block 8 is set as an inclined surface. When the slider 4 presses the inclined surface, the inclined block 8 moves to the left and the inclined surface contacts the bottom part of the slider 4. The insert 6 is inserted into the inner wall of the storage box 1. The storage box 1 has two sets of slots corresponding to the insert 6. The insert 6 is initially inserted into the first slot.
[0039] Reference Figures 5-7The bottom part of the movable block 10 is in contact with the inner wall of the storage box 1. The storage box 1 supports the movable block 10. The slider 4 is slidably connected to the inner wall of the storage box 1. The storage box 1 has a slot corresponding to the slider 4, allowing the slider 4 to move vertically. The outer wall of the temperature sensing wire 12 is in contact with the inner wall of the storage box 1. The temperature sensing wire 12 is wound around the outer wall of the rotating column 13.
[0040] Working principle: When temperature measurement is required, manually move the insert block 6 backward. The insert block 6 will compress the movable spring 7. When the insert block 6 separates from the slot on the storage box 1, manually move the insert block 6 downward. The insert block 6 will move the slider 4 and the hinge rod 3 downward. The other end of the hinge rod 3 will cause the opening and closing cover 2 to flip upward. The opening and closing cover 2 will flip open with the hinge point with the storage box 1 as the center. As the slider 4 moves downward, when the slider 4 compresses the inclined block 8, the inclined block 8 will move to the left and compress the movable spring 9. At this time, the inclined block 8 will move the movable block 10 and the temperature probe 11 to the right. After the head 11 moves a certain distance to the right, the opening and closing cover 2 is fully opened to a horizontal state. At the same time, the insert 6 coincides with the second slot on the storage box 1. Manually release the insert 6, and use the elasticity of the movable spring 7 to insert the insert 6 into the slot of the storage box 1, thus completing the limitation of the movable block 10. Then, the staff can manually pull out the temperature probe 11 to the right. The temperature probe 11 will move backward with the temperature sensing wire 12. The temperature sensing wire 12 will rotate counterclockwise with the rotating column 13 and compress the torsion spring 14. At this time, the staff can use the temperature probe 11 to measure the temperature, and the temperature will be displayed on the monitor.
[0041] After temperature measurement is completed, manually release the temperature probe 11. Under the elastic force of the torsion spring 14, it will move the rotating column 13 back to its initial position. The rotating column 13 will then pull the temperature sensing wire 12 back into the device. Figure 2 In the state shown, the operator can then manually move the insert 6 backward. When the insert 6 separates from the slot on the storage box 1, the operator can manually move the insert 6 vertically. The insert 6 will move upward along with the slider 4 and the moving rod 5. As the slider 4 no longer contacts the inclined block 8, it will move to the initial position along with the inclined block 8 and the movable block 10 under the elastic force of the moving spring 9. The movable block 10 will move the temperature probe 11 back into the device. At the same time, the slider 4 will move upward along with the hinge rod 3. The other end of the hinge rod 3 will flip the opening and closing cover 2 downward. The opening and closing cover 2 will flip and close with the hinge point with the storage box 1 as the center. When the opening and closing cover 2 is closed, the insert 6 will coincide with the first slot on the storage box 1. The operator can then manually release the insert 6 and insert it into the slot of the storage box 1 to complete the limiting of the opening and closing cover 2. If temperature measurement is required again, the above operation steps can be repeated.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
