[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This application provides an engine speed sensor that is easy to install and remove, solving the problem that existing installation methods make it inconvenient to disassemble and install the sensor body during subsequent maintenance, thus making the inspection and maintenance of the sensor body inconvenient. During maintenance, the entire sensor housing needs to be disassembled, which is time-consuming and labor-intensive.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example 1:

[0033] This utility model discloses an engine speed sensor that is easy to install and disassemble, according to the attached... Figure 1-4 As shown, it includes a sensor base 1, a partition plate 2, a sensor core base 3, a connecting frame 4, and a locking unit 5;

[0034] Sensor base 1 is used as the foundation for fixing the target position of the sensor; sensor base 1 is the basic support component of the entire engine speed sensor and is designed to be stably installed on the engine.

[0035] The partition plate 2 is set on the sensor base 1. The main function of the partition plate 2 on the sensor base 1 is to position and support the sensor core 3, so that the sensor core 3 can be quickly assembled, positioned and replaced.

[0036] The sensor core 3 is a sensing element for detecting engine speed and is movably snapped between the two sets of partition plates 2; the sensor core 3 is the core component for detecting engine speed, and integrates sensing elements and signal processing circuits inside.

[0037] The connecting bracket 4 is set on the sensor base 1; the connecting bracket 4 is set on the sensor base 1 to provide an installation platform for the locking unit 5, ensuring that the overall structure of the sensor is reasonably designed, ensuring that the locking unit 5 is easy to operate, and making the disassembly and assembly of the sensor core seat 3 convenient.

[0038] The locking unit 5 is located between the connecting frame 4 and the sensor base 1 and is used to lock the position of the sensor core seat 3.

[0039] A fitting block 21 is connected to the partition plate 2, and a fitting groove 31 is provided on the sensor core base 3. The fitting groove 31 is engaged with the fitting block 21. The engagement between the fitting groove 31 and the fitting block 21 ensures the precise positioning of the sensor core base 3 in the horizontal and vertical directions.

[0040] The sensor core holder 3 has a locking hole 32, and the locking unit 5 includes:

[0041] Guide rail rod 51 is mounted on connecting frame 4;

[0042] Adjusting block 52 is movable and locked onto guide rail rod 51;

[0043] Support block 53 is mounted on adjustment block 52;

[0044] The locking rod 54 is mounted on the support block 53 and is movably inserted into the locking hole 32.

[0045] A double-threaded screw 55 is rotatably connected to the connecting frame 4, and the double-threaded screw 55 is threadedly connected to the adjusting block 52.

[0046] The sensor base 1 has a movable groove 12 corresponding to the position of the support block 53. The movable groove 12 limits the movement of the support block 53, ensuring the ease of use of the locking unit 5.

[0047] The locking unit 5 has a simple structure, which ensures the stable fixing of the sensor core 3 when fixing its position, and also makes the sensor core 3 easy to assemble and disassemble.

[0048] When installing the sensor core holder 3, first align the sensor core holder 3 between the two sets of partition plates 2 and snap it in place. The fitting groove 31 is engaged with the fitting block 21. At this time, rotate the double threaded screw 55, which drives the adjusting block 52 to move. The adjusting block 52 slides along the guide rail 51, and the adjusting block 52 drives the support block 53 and the locking rod 54 to move. Finally, the locking rod 54 is inserted into the locking hole 32, which quickly fixes the sensor core holder 3. When the sensor core holder 3 needs to be maintained later, it is convenient to quickly disassemble the sensor core holder 3. The operation method is the reverse of the installation process.

[0049] The double-threaded lead screw 55 is equipped with a rotating handle 551, which makes the rotation operation of the double-threaded lead screw 55 convenient through the design of the rotating handle 551.
