Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to a piezoelectric injection valve temperature sensor mounting mechanism. Background Technology

[0002] The design of the temperature sensor mounting mechanism for the piezoelectric injection valve is primarily for accurately monitoring the valve body temperature, ensuring the reliability and stability of the injection system.

[0003] First, if the installation is unstable, the sensor is prone to loosening due to vibration and pressure fluctuations during operation, leading to measurement errors or even device failure. Moreover, it cannot guarantee good contact between the sensor and the valve body, increasing thermal resistance and causing temperature measurement delay or reduced accuracy.

[0004] Secondly, disassembly and assembly require a significant amount of time, especially in compact or hard-to-reach environments. Manual or non-standard installation methods may result in stripped threads, seal failure, or damage to the sensor housing.

[0005] Finally, without any protective measures after installation, the device is easily damaged by external moisture or liquid impurities, which could damage the sensors installed inside the main body. Utility Model Content

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5A piezoelectric injection valve temperature sensor mounting mechanism includes a main body 1, a fixing mechanism, and a mating mechanism. The fixing mechanism includes a pressure plate 2, fixing bolts 3, a cover plate 4, and a mounting component 5. The pressure plate 2 is mounted on the main body 1 and mating with it. The fixing bolts 3 are mounted on the pressure plate 2 and mating with it. The cover plate 4 is fixedly mounted on the main body 1 and mating with it. The mounting component 5 is fixedly installed inside the main body 1. The mating mechanism includes a toggle lever 6, a spring 7, a stop lever 8, a mating sleeve 9, and auxiliary components. The toggle lever 6 is mounted on the main body 1 and slidably connected to it. The spring 7 is fixedly mounted at the bottom of the toggle lever 6, and its other end is fixedly connected to the stop lever 8. The mating sleeve 9 is mounted on the toggle plate and mating with it, and slidably connected to the stop lever 8.

[0031] In this embodiment, the fixing mechanism includes a pressure plate 2, fixing bolts 3, a cover plate 4, and a mounting component 5. In use, the main body 1 is installed on the valve body, and then the pressure plate 2 is placed into the embedding groove 12 of the main body 1. Then, the fixing bolts 3 are inserted into the mounting groove 13 on the pressure plate 2, thereby installing the main body 1 on the valve body. Then, the mounting component 5 is placed inside the main body 1, and then a buffer pad 10 is placed on the mounting component 5. Finally, the cover plate 4 is installed, thereby fixing the mounting component 5 inside the main body 1 and making contact with the valve body for operation. During the process of placing the mounting component 5, the wire on the mounting component 5 is connected to the outside through the wire hole 14.

[0032] In this embodiment, the mating mechanism includes a lever 6, a spring 7, a stop lever 8, a mating sleeve 9, and auxiliary components. During use, the cover plate 4 is already installed on the main body 1. The stop lever 8 is first inserted into the main body 1, and then moved so that the limiting plate 16 at the bottom of the stop lever 8 can slide in the limiting groove 15 inside the main body 1. After sliding to the bottom of the limiting groove 15, the lever 6 is installed on the stop lever 8. Because of the installation of the lever 6, the mating sleeve 9 also contacts the stop lever 8. The mating sleeve 9 can then be pressed and rotated. The insertion rod 19 on the mating sleeve 9 rotates inside the stop lever 8, while the locking block 20 slides in the entry groove 17 and eventually enters the fixing groove 18 on the stop lever 8. During the installation process, the mating sleeve 9... The lever slids on the actuating rod 6 and eventually pushes the wave rod into the second slot 22. The stop rod 8 also compresses the spring 7 and enters the first slot 21 under the cooperation of the locking block 20 and the fixing slot 18 of the entry slot 17. This makes the installation between the cover plate 4 and the main body 1 extremely fixed. After installation, the sealing slot 23 on the cover plate 4 is empty. At this time, the sealing sleeve 11 can be installed into the sealing slot 23 to seal the surface of the cover plate 4. When replacing the internal mounting parts 5, the mating sleeve 9 can be pressed and rotated directly to make the mating sleeve 9 disengage from the fixing slot 18 and enter the entry slot 17. This makes the limiting plate 16 on the stop rod 8 disengage from the first slot 21 and enter the limiting slot 15, thereby sliding the stop rod 8 to complete the disassembly of the cover plate 4.

[0033] Example 2:

[0034] In summary, during use, the main body 1 must first be installed onto the valve body. After the main body 1 is installed, the pressure plate 2 is placed into the embedding groove 12 of the main body 1. Then, the fixing bolts 3 are inserted into the mounting groove 13 on the pressure plate 2, thereby installing the main body 1 onto the valve body. Next, the mounting component 5 is placed inside the main body 1, followed by a buffer pad 10 on the mounting component 5. Finally, the cover plate 4 is installed, thus fixing the mounting component 5 inside the main body 1 and allowing it to contact the valve body for operation. During the insertion of the mounting component 5... The wire on the mounting piece 5 is connected to the outside through the through hole 14. Then, the cover plate 4 is fixed. After the cover plate 4 is installed on the main body 1, the stop rod 8 can be inserted into the main body 1 and moved so that the limiting plate 16 at the bottom of the stop rod 8 can slide in the limiting groove 15 inside the main body 1. After sliding to the bottom of the limiting groove 15, the actuating rod 6 is installed on the stop rod 8. Because of the installation of the actuating rod 6, the mating sleeve 9 also contacts the stop rod 8. At this time, it can be pressed. Furthermore, the rotating fitting sleeve 9 causes the insertion rod 19 on the fitting sleeve 9 to rotate inside the stop rod 8, while the locking block 20 slides in the entry groove 17 and eventually enters the fixing groove 18 on the stop rod 8. During installation, the fitting sleeve 9 slides on the actuating rod 6 and eventually pushes the wave rod into the second locking groove 22. The stop rod 8, under the cooperation of the locking block 20 and the fixing groove 18 of the entry groove 17, compresses the spring 7 and enters the first locking groove 21, thereby making the installation between the cover plate 4 and the main body 1 extremely precise. To fix it, and after installation, the sealing groove 23 on the cover plate 4 is empty. At this time, the sealing sleeve 11 can be installed into the sealing groove 23 to seal the surface of the cover plate 4. When replacing the internal mounting part 5, the mating sleeve 9 can be pressed and rotated directly to disengage it from the fixing groove 18 and enter the entry groove 17, so that the limiting plate 16 on the stop rod 8 disengages from the first slot 21 and enters the limiting groove 15, thereby sliding the stop rod 8 and completing the disassembly of the cover plate 4.

[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
