Technical Field

[0001] This utility model belongs to the field of explosion-proof structure technology, and in particular relates to a temperature measuring device with a composite explosion-proof structure. Background Technology

[0002] A temperature measuring device is a device used to measure the temperature of an object. Depending on the measurement method and application scenario, there are many types of temperature measuring devices, which can be roughly divided into two categories: contact temperature measuring devices and non-contact temperature measuring devices. These two different types of temperature measuring devices are used in different scenarios.

[0003] Currently, temperature measuring devices are generally equipped with an external protective structure, which is an integrated design with the temperature measuring device. This makes it difficult to inspect the device when it is damaged. Furthermore, if the external protective structure is damaged, the entire device needs to be replaced, which is wasteful of resources and impractical. To solve these problems, there is an urgent need for a temperature measuring device with a composite explosion-proof structure. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that current temperature measuring devices generally have an external protective structure, which is an integral design of the temperature measuring device. This makes it difficult to inspect the temperature measuring device when it is damaged. At the same time, if the externally assembled protective structure is damaged, the entire device needs to be replaced, which wastes resources and is not practical. Therefore, this utility model proposes a temperature measuring device with a composite explosion-proof structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature measuring device with a composite explosion-proof structure, comprising a first explosion-proof frame and a second explosion-proof frame, wherein the second explosion-proof frame is disposed below the first explosion-proof frame, and both the first and second explosion-proof frames are provided with mounting grooves on their inner sides, wherein a temperature measuring device is disposed on the inner side of the mounting grooves, and a connecting assembly is movably disposed within the shell cavity of the second explosion-proof frame, wherein the connecting assembly includes a side-top spring, the side-top spring is fixedly installed on the inner wall of one side of the shell cavity of the second explosion-proof frame, and a movable plate is fixedly installed at one end of the side-top spring.

[0006] As a further description of the above technical solution:

[0007] Both ends of the movable plate are slidably connected to the inner wall of the shell cavity of the second explosion-proof frame, and multiple positioning pins are fixedly installed on one outer wall of the movable plate.

[0008] As a further description of the above technical solution:

[0009] One end of the movable plate is fixedly installed with an outward protruding shaft, and the outer side of the second explosion-proof frame is provided with a stroke groove.

[0010] As a further description of the above technical solution:

[0011] One end of the protruding shaft passes through and extends to the outside of the travel groove, and a positioning insert is fixedly installed on the bottom surface of the first explosion-proof frame.

[0012] As a further description of the above technical solution:

[0013] The top surface of the second explosion-proof frame is provided with a positioning groove that is compatible with the positioning insert plate, and one side of the positioning groove is provided with multiple inner holes.

[0014] As a further description of the above technical solution:

[0015] One end of the positioning pin is slidably connected to the inner hole, and the side wall of the positioning plate is provided with a positioning hole that is compatible with the positioning pin.

[0016] As a further description of the above technical solution:

[0017] The first explosion-proof frame and the second explosion-proof frame have the same volume and size. The inner surfaces of the first explosion-proof frame and the second explosion-proof frame are provided with a high-temperature resistant material layer. The first explosion-proof frame and the second explosion-proof frame are both composed of steel, glass fiber reinforced composite material and nano composite material.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by designing the temperature measuring structure as a detachable assembly type, during assembly, it is only necessary to place the thermometer in the mounting groove of the second explosion-proof frame, directly align the first explosion-proof frame with the second explosion-proof frame, and pull the moving plate by the external convex shaft to move each positioning side pin to the side, so that each positioning side pin retracts into the shell cavity of the second explosion-proof frame. At this time, the positioning insert plate can be inserted into the interior of the positioning groove. Then, release the external convex shaft, and the moving plate can be reset under the action of the side top spring. The positioning side pin can pass through the inner hole and be inserted into the positioning hole on the side wall of the positioning insert plate. At this time, the first explosion-proof frame and the second explosion-proof frame are positioned, and the assembly of the overall temperature measuring device is completed. In subsequent disassembly, the external convex shaft can be moved to the side to complete the disassembly. Through this design, the disassembly and assembly of the temperature measuring structure can be completed quickly. If the external explosion-proof structure is damaged, only one part needs to be replaced, avoiding resource waste. Moreover, if the thermometer malfunctions, it can be quickly and comprehensively inspected, improving the practicality of the overall device.

[0020] 2. In this utility model, the first explosion-proof frame and the second explosion-proof frame are composed of steel, glass fiber reinforced composite material and nano composite material. The above composite material can greatly improve the strength of the explosion-proof structure and can stably protect the temperature measuring device when an external explosion occurs, thereby protecting the test data inside the temperature measuring device and improving the overall structure's performance.

Detailed Implementation

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4This utility model provides a technical solution: a temperature measuring device with a composite explosion-proof structure, including a first explosion-proof frame 1 and a second explosion-proof frame 2. The second explosion-proof frame 2 is arranged below the first explosion-proof frame 1. The inner sides of both the first explosion-proof frame 1 and the second explosion-proof frame 2 are provided with mounting grooves 3. A thermometer 10 is arranged inside the mounting groove 3. A connecting component 6 is movably arranged inside the shell cavity of the second explosion-proof frame 2. The connecting component 6 includes a side-top spring 62. The side-top spring 62 is fixedly installed on the inner wall of one side of the shell cavity of the second explosion-proof frame 2. A movable plate 61 is fixedly installed at one end of the side-top spring 62.

[0029] Both ends of the movable plate 61 are slidably connected to the inner wall of the shell cavity of the second explosion-proof frame 2. A plurality of positioning side pins 64 are fixedly installed on one side of the outer wall of the movable plate 61. An externally protruding shaft 63 is fixedly installed on one end of the movable plate 61. A stroke groove 9 is provided on the outer side of the second explosion-proof frame 2. One end of the externally protruding shaft 63 passes through and extends to the outer side of the stroke groove 9. A positioning insert plate 5 is fixedly installed on the bottom surface of the first explosion-proof frame 1. A positioning groove 7 that is compatible with the positioning insert plate 5 is provided on the top surface of the second explosion-proof frame 2. A plurality of inner holes 8 are provided on one side of the positioning groove 7. One end of the positioning side pin 64 is slidably connected to the inner hole 8. A positioning hole 4 that is compatible with the positioning side pin 64 is provided on the side wall of the positioning insert plate 5.

[0030] The specific implementation method is as follows: During assembly, the thermometer 10 is placed in the mounting slot 3 of the second explosion-proof frame 2, and the first explosion-proof frame 1 and the second explosion-proof frame 2 are aligned directly. The moving plate 61 is pulled by the external convex shaft 63, so that the moving plate 61 drives each positioning side pin 64 to move laterally, so that each positioning side pin 64 is retracted into the shell cavity of the second explosion-proof frame 2. At this time, the positioning insert plate 5 can be inserted into the interior of the positioning slot 7. At this time, the external convex shaft 63 is released, and the moving plate 61 can be reset under the action of the side top spring 62. The positioning side pin 64 can pass through the inner hole 8 and be inserted into the positioning hole 4 on the side wall of the positioning insert plate 5. At this time, the first explosion-proof frame 1 and the second explosion-proof frame 2 are positioned, and the assembly of the overall temperature measuring device is completed. In the subsequent disassembly, the external convex shaft 63 can be moved laterally to complete the disassembly.

[0031] The first explosion-proof frame 1 and the second explosion-proof frame 2 have the same volume and size. The inner surfaces of the first explosion-proof frame 1 and the second explosion-proof frame 2 are provided with a high-temperature resistant material layer 11. The first explosion-proof frame 1 and the second explosion-proof frame 2 are both composed of steel, glass fiber reinforced composite material and nano composite material.

[0032] The specific implementation method is as follows: the first explosion-proof frame 1 and the second explosion-proof frame 2 are composed of steel, glass fiber reinforced composite material and nano composite material. The above composite material can greatly improve the strength of the explosion-proof structure and can stably protect the temperature measuring device 10 when an external explosion occurs, thereby protecting the test data inside the temperature measuring device 10.

[0033] Working principle: During assembly, simply place the thermometer 10 into the mounting slot 3 of the second explosion-proof frame 2, align the first explosion-proof frame 1 with the second explosion-proof frame 2, and pull the moving plate 61 laterally through the external convex shaft 63. This causes the moving plate 61 to move the positioning pins 64 laterally, allowing them to retract into the cavity of the second explosion-proof frame 2. At this point, the positioning insert 5 can be inserted into the positioning slot 7. Releasing the external convex shaft 63 allows the moving plate 61 to reset under the action of the side spring 62, and the positioning pins 64 can pass through the inner hole 8. Insert the first explosion-proof frame 1 and the second explosion-proof frame 2 into the positioning hole 4 on the side wall of the positioning plate 5. At this time, the first explosion-proof frame 1 and the second explosion-proof frame 2 are positioned and the assembly of the overall temperature measuring device is completed. In subsequent disassembly, the outer convex shaft 63 can be directly moved to the side to complete the disassembly. Since the first explosion-proof frame 1 and the second explosion-proof frame 2 are composed of steel, glass fiber reinforced composite material and nano composite material, the above composite material can greatly improve the strength of the explosion-proof structure and can stably protect the temperature measuring device 10 in the event of an external explosion, thereby protecting the test data inside the temperature measuring device 10.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
