Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, and particularly relates to a combined measuring instrument. Background Art

[0002] A combined measuring instrument is a measuring device composed of multiple components. It can combine different measuring units as needed to complete more complex and accurate measuring tasks. This type of measuring instrument usually has a modular design, and each component can be used independently or in combination with other components to meet diverse measuring needs.

[0003] Traditional combined inspection tools for measuring railway locomotives usually have some inherent limitations. For example, they may be complex in design, and users need to spend more time and effort when adjusting or replacing components, which to a certain extent affects work efficiency. In addition, the locking mechanisms of traditional measuring instruments are often costly and require high precision in the manufacturing and assembly processes, increasing production costs. And when a part of these measuring instruments, such as the probe, fails, it often needs to be replaced as a whole, which not only increases the economic burden on users but also is not conducive to resource conservation and environmental protection. In addition, in extreme high-temperature conditions, railway vehicle signal workers need to perform maintenance between the sun-baked locomotive shell and the electromechanical equipment that has just stopped rotating and still has residual heat. At positions on the locomotive bottom that cannot be detected by an infrared thermal imaging detector, a hand-held thermometer is often used for detection. In this case, the probe of the thermometer often gets damaged, and the detection efficiency for continuous detection of long train sections is relatively low. Summary of the Utility Model

[0004] In view of the above-mentioned technical problems, a combined measuring instrument is provided. The technical means adopted by the utility model are as follows:

[0005] A combined measuring instrument includes an instrument body, an assembly block, and a measuring probe. A connecting sleeve is fixedly connected to the lower surface of the instrument body. Positioning holes are provided on the outer surface of the connecting sleeve. The assembly block is snap-connected to the connecting sleeve through the positioning holes. A connecting member is arranged below the assembly block, and the measuring probe is detachably connected through the connecting member.

[0006] Further, a preset groove is provided on the outer surface of the assembly block, and a pressing block matching the specification of the preset groove is further included. The assembly block is fixed to the connecting sleeve through the pressing block.

[0007] Further, the number of the preset grooves is two, which are respectively provided on both sides of the outer surface of the assembly block. Correspondingly, the number of the pressing blocks is also two.

[0008] Further, a telescopic spring is fixedly connected inside the preset groove, and one end of the telescopic spring is fixedly connected to the pressing block.

[0009] Further, the inner diameter of the external connection sleeve is larger than the outer diameter of the assembly block, and the inner diameter of the external connection sleeve is also larger than the length between the two pressing blocks after the pressing block is in a compressed state.

[0010] Further, the connecting member includes a screw hole opened at the bottom of the assembly block and a mounting screw. The bottom end of the mounting screw is fixedly connected to the upper surface of the rubber pad, and a measuring probe is fixedly connected to the lower surface of the rubber pad. The detachable connection between the measuring probe and the assembly block is realized through the cooperation of the mounting screw and the screw hole.

[0011] By setting the mounting screw and utilizing its cooperation with the internal thread hole, the utility model effectively connects the measuring probe with the assembly block, realizes the quick installation and disassembly of the thermometer probe, enables the user to only replace the probe itself when the probe fails, without replacing the entire thermometer, reduces the maintenance cost and resource waste, and the user can easily press the pressing block into the preset groove by external force. When the external force is removed, the restoring force of the telescopic spring will automatically drive the pressing block to reset and snap into the positioning hole to achieve locking, which not only improves the working efficiency but also reduces the manufacturing and assembly costs caused by complex locking mechanisms.

[0012] The utility model has the following advantages:

[0013] 1. It is easy to assemble and disassemble, enabling the user to quickly adjust or replace components.

[0014] 2. Each component can be used independently or in combination with other components to meet diverse measurement requirements.

[0015] 3. The maintenance cost is reduced. When the lower component needs to be replaced, it can be directly disassembled and replaced. For the situation of probe damage during the detection of high-temperature locomotive car bodies, only the spare probe needs to be assembled onto the instrument body, which is convenient for continuous operation and also extends the overall service life of the measuring instrument in a way.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 5 shown, an embodiment of the present utility model discloses a combined measuring appliance, including an appliance body 1. The lower surface of the appliance body 1 is fixedly connected with an external connection sleeve 2. The outer surface of the external connection sleeve 2 is provided with positioning holes 3. The external connection sleeve 2 is clamped with an assembly block 4 through the positioning holes 3. The appliance body 1 serves as the main temperature measuring element, responsible for sensing the temperature and converting it into a readable signal for display to the user. The external connection sleeve 2 is a fixing device and serves as an interface, enabling other components to be connected to the appliance body 1. The positioning holes 3 are opened on the outer surface of the external connection sleeve 2. These positioning holes 3 can ensure that the assembly block 4 can be accurately aligned when connected to the external connection sleeve 2, thereby ensuring the measurement accuracy of the appliance body 1. In this embodiment, the appliance body is specifically a thermometer that is convenient to hold.

[0025] The outer surface of the assembly block 4 is provided with a preset groove 5. The preset groove 5 can provide additional fixing points to facilitate the more secure fixing of the assembly block 4 on the external connection sleeve 2 using the pressing block 7.

[0026] There are two preset slots 5, which are respectively opened on both sides of the outer surface of the assembly block 4. The design of the two preset slots 5 can provide better symmetry for the assembly block 4, which helps to maintain balance during assembly and makes the thermometer more stable during use.

[0027] A telescopic spring 6 is fixedly connected inside the preset slot 5. One end of the telescopic spring 6 is fixedly connected to a pressing block 7. The telescopic spring 6 is an elastic element that can bear compressive force. It is fixed inside the preset slot 5, with one end fixedly connected to the slot wall and the other end fixedly connected to the pressing block 7. When the pressing block 7 is pressed by an external force, the telescopic spring 6 will be compressed and store energy; when the external force is removed, the telescopic spring 6 returns to its original state, driving the pressing block 7 to reset and snap into the positioning hole 3, thereby realizing quick locking or unlocking of the assembly block 4. This enables the user to quickly adjust or replace the assembly block 4, improving work efficiency. After the pressing block 7 is released, the restoring force of the telescopic spring 6 can help maintain the firm connection between the pressing block 7 and the assembly block 4, reducing loosening problems caused by vibration or other external forces.

[0028] The pressing block 7 is adapted to the positioning hole 3. An internal threaded hole 8 is opened in the middle of the lower surface of the assembly block 4. The design of the pressing block 7 is for use in cooperation with the positioning hole 3. When the pressing block 7 is pressed into the preset slot 5, it can be engaged with the external connection sleeve 2 through the positioning hole 3, thus firmly connecting the assembly block 4 and the external connection sleeve 2 together.

[0029] An installation screw 9 is arranged inside the internal threaded hole 8. The assembly block 4 is threadedly connected with a rubber pad 10 through the internal threaded hole 8. The installation screw 9 is a rod-shaped object with an external thread, which cooperates with the internal threaded hole 8 to connect the measuring probe 11 to the assembly block 4.

[0030] The bottom end of the installation screw 9 is fixedly connected to the upper surface of the rubber pad 10. The lower surface of the rubber pad 10 is fixedly connected to the measuring probe 11. The rubber pad 10 is made of an elastic material. It can closely fit on the surface of the measured device, and due to its elastic characteristics, it can compensate for small unevenness on the surface of the measured device, ensuring good contact between the measuring probe 11 and the surface of the measured device.

[0031] In the embodiment of the present application, the implementation principle of a combined measuring instrument is as follows: The user tightly connects the lower surface of the instrument body 1 with the upper surface of the external connecting sleeve 2 to ensure there is no gap between them. Then, the instrument body 1 is fixed to the external connecting sleeve 2 by screws or other fixing methods to form a stable structure. Place the assembly block 4 on the external connecting sleeve 2, align the preset groove 5 with the positioning hole 3. Subsequently, press the pressing block 7 so that it is embedded in the preset groove 5. While pressing, gently push the assembly block 4 until it is felt that the assembly block 4 is tightly connected to the external connecting sleeve 2. Release the pressing block 7. Due to the restoring force of the telescopic spring 6, the pressing block 7 will automatically pop out and be stuck into the positioning hole 3 to complete the fixation of the assembly block 4. Connect the probe to the assembly block 4 through the mounting screw 9 to ensure that the probe is firmly installed in the internal thread hole 8 on the lower surface of the assembly block 4 to ensure the stability of the probe during use. The rubber pad 10 is made of elastic material. It can closely fit on the surface of the device under test, and due to its elastic characteristics, it can compensate for small unevenness on the surface of the device under test to ensure good contact between the measuring probe 11 and the surface of the device under test. When the working probe is damaged, continuous operation can be achieved by replacing the spare probe.

[0032] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
