[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 1-4 The present invention provides the following technical solution:

[0031] A modular wireless torque sensor quick-change probe, comprising:

[0032] Main unit casing 1;

[0033] Host communication module 2 is fixedly connected to the lower inner wall of host housing 1;

[0034] The sensor probe base 3 is inserted into the main unit housing 1;

[0035] Torque sensing probe module 4 is fixedly connected to the upper end of sensing probe base 3.

[0036] The host electrical contact 5 is connected to the upper end of the host communication module 2, and the host electrical contact 5 is electrically connected to the host communication module 2.

[0037] The probe electrical contact 6 is connected to the lower end of the sensing probe base 3. The probe electrical contact 6 is electrically connected to the torque sensing probe module 4. The host electrical contact 5 and the probe electrical contact 6 are in contact.

[0038] The replacement components are provided in two sets, each set of which is located inside the sensor probe base 3 to enable quick replacement of the torque sensor probe module 4.

[0039] In a specific embodiment of this utility model, when the user aligns the sensor probe base 3 with the upper opening of the main unit housing 1 and inserts it, the sensor probe base 3 gradually enters the interior of the main unit housing 1. Thus, the torque sensor probe module 4, fixedly connected to the upper end of the sensor probe base 3, is positioned accordingly. Simultaneously, the probe electrical contact 6 connected to its lower end contacts and abuts with the host electrical contact 5 connected to the upper end of the host communication module 2. Thus, the host electrical contact 5 is electrically connected to the host communication module 2, and the probe electrical contact 6 is electrically connected to the torque sensor probe module 4, establishing a signal path. Personnel can use the replacement components to detach the sensor probe base 3 from the main unit housing 1, achieving not only modularity of the main unit housing 1 and the host communication module 2, but also rapid replacement of the torque sensor probe module 4.

[0040] Please refer to the details. Figures 1-4 Each replacement component includes a slot 7, a slide 8, a first spring 9, a locking block 10, a sliding hole 11, a push plate 12, a pressing push rod 13, and a second spring 14. The slot 7 is opened on the inner circumference of the main unit housing 1, the slide 8 is opened on the circumference of the sensor probe base 3, one end of the first spring 9 is fixedly connected to one side of the slide 8, the locking block 10 is fixedly connected to the other end of the first spring 9, the locking block 10 is slidably connected in the slide 8, the sliding hole 11 is opened on the circumference of the main unit housing 1 and communicates with the slot 7, the push plate 12 is slidably connected in the slot 7, the pressing push rod 13 is fixedly connected to one side of the push plate 12, and the second spring 14 is sleeved on the circumference of the pressing push rod 13, with one end of the second spring 14 attached to the circumference of the main unit housing 1.

[0041] In this embodiment: when the user inserts the sensor probe base 3 into the main unit housing 1, the slide groove 8 on the circumferential surface of the sensor probe base 3 moves accordingly. The locking block 10, initially partially extending out of the slide groove 8 under the push of the first spring 9, is then compressed and slides into the slide groove 8 when it contacts the inner wall of the main unit housing 1. The first spring 9 is compressed. When the locking block 10 continues to descend until it aligns with the slot 7 on the inner circumferential wall of the main unit housing 1, the locking block 10 quickly springs into the slot 7 under the elastic force of the first spring 9, achieving mechanical locking. Thus, the sensor probe base 3 is fixed in the main unit housing 1. When disassembly is required, the user presses the push rod 13 located on the outside of the main unit housing 1. This pushes the push plate 12 to slide within the sliding hole 11 and pushes the locking block 10 out of the slot 7. The second spring 14 is then compressed, and the locking block 10 is completely disengaged. After disengaging from the slot 7, the sensor probe base 3 can be pulled out of the main unit housing 1. During installation, the user only needs to insert the sensor probe base 3 into the main unit housing 1, and the locking block 10 will automatically spring into the slot 7 under the action of the first spring 9, thus quickly completing the installation. During disassembly, the user only needs to press the pressing push rod 13 on the outside of the main unit housing 1, which will drive the push plate 12 to slide in the sliding hole 11 and push the locking block 10 out of the slot 7, thus quickly completing the disassembly. This reduces the steps and time required to replace the probe and improves the efficiency of personnel replacement. It should be noted that the sensor probe base 3 has a through hole that allows the probe electrical contact 6 to be electrically connected to the torque sensor probe module 4. Furthermore, the slot 7 and the main unit electrical contact 5 are at the same distance from the sliding groove 8 and the probe electrical contact 6. When the user installs the sensor probe base 3, the main unit electrical contact 5 and the probe electrical contact 6 will make stable contact with each other.

[0042] Please refer to the details. Figures 1-4 Two third springs 15 are fixedly connected to the upper end of the host communication module 2, and a stop block 16 is fixedly connected to the upper end of each third spring 15.

[0043] In this embodiment: when the user presses the push rods 13 on both sides to disengage the locking block 10 from the slot 7, the sensor probe base 3 loses its mechanical lock. In this way, the third spring 15 quickly releases its potential energy, pushing the abutment block 16 to move upward. The abutment block 16 quickly pops the sensor probe base 3 out of the main unit housing 1, which the user can easily remove and replace.

[0044] Please refer to the details. Figures 1-4 Two guide grooves 17 are respectively opened on the inner circumference of the main unit housing 1, and two guide blocks 18 are respectively fixedly connected to the circumference surface of the sensor probe base 3. A guide block 18 is slidably connected in each guide groove 17.

[0045] In this embodiment: when the sensor probe base 3 is inserted along the axial direction of the main unit housing 1, the two guide blocks 18 fixed on its circumferential surface are aligned with the two guide grooves 17 opened on the inner wall of the main unit housing 1. In this way, the guide blocks 18 slide in the guide grooves 17, which restricts the rotation and offset of the sensor probe base 3. This ensures that the locking block 10 can be accurately aligned with the locking groove 7 and ensures the precise alignment and connection between the probe electrical contact 6 and the main unit electrical contact 5.

[0046] Please refer to the details. Figures 1-4 The upper opening of the main unit casing 1 is an arc-shaped bevel, and the lower end of the card block 10 is a bevel. The bevel at the opening of the main unit casing 1 matches the bevel of the card block 10.

[0047] In this embodiment: when the sensor probe base 3 is inserted into the main unit housing 1, the arc-shaped inclined surface at the upper opening of the main unit housing 1 contacts the inclined surface at the lower end of the locking block 10. In this way, the inclined surface structure guides the locking block 10 to be gently pressed into the sliding groove 8 during the insertion process, reducing the insertion resistance. The personnel only need to insert the sensor probe base 3 into the main unit housing 1, and the locking block 10 will automatically spring into the locking groove 7 under the action of the first spring 9, realizing the rapid installation of the torque sensor probe module 4.

[0048] Please refer to the details. Figures 1-4 A gasket 19 is fixedly connected to the lower end of the main unit casing 1, and a magnetic block 20 is embedded in the gasket 19.

[0049] In this embodiment: when the main unit housing 1 is placed on a metal workbench or equipment surface, the pad 19 fixedly connected to its lower end is in contact with the contact surface. In this way, the magnetic block 20 embedded in the pad 19 generates an adsorption force, so that the entire device can be easily adsorbed on ferromagnetic surfaces such as car bodies, machine housings, and metal brackets, freeing the operator's hands and facilitating observation, reading, and other operations.

[0050] Please refer to the details. Figures 1-4 The main unit electrical contacts 5 and the probe electrical contacts 6 are plated with gold. When the sensor probe base 3 is inserted into the main unit housing 1, the main unit electrical contacts 5 and the probe electrical contacts 6 are in contact.

[0051] In this embodiment: When the probe electrical contact 6 and the host electrical contact 5 are in contact with each other, both surfaces are plated with a gold layer. This effectively prevents oxidation and corrosion during frequent insertion and removal, maintaining good conductivity. Thus, when the sensor probe base 3 is fully inserted into the host housing 1, a reliable electrical connection is formed between the gold-plated electrical contacts, ensuring continuous signal transmission. Workflow: When installing the operating torque sensor probe module 4, the operator holds the sensor probe base 3 with the assembled torque sensor probe module 4, aligning it with the upper opening of the host housing 1. The two guide blocks 18 on the outer periphery of the sensor probe base 3 are aligned with the guide groove 17 on the inner wall of the host housing 1, ensuring that the probe base can only slide axially during insertion, preventing rotation or offset, and ensuring precise docking of the subsequent electrical contacts with the snap-fit ​​structure. The upper opening of the host housing 1 is an arc-shaped bevel, matching the bevel at the lower end of the snap-fit ​​block 10. When the probe base is inserted, the inclined structure guide block 10 smoothly presses into the slide groove 8, compressing the first spring 9 to reduce insertion resistance and improve assembly smoothness. As the sensor probe base 3 continues to descend, its bottom probe electrical contact 6 gradually approaches the top host electrical contact 5 of the host communication module 2. Both surfaces are gold-plated to ensure good conductivity during frequent insertion and removal, preventing oxidation that could cause signal interruption. When the block 10 descends to align with the slot 7 on the inner wall of the host housing 1, the compressed first spring 9 releases its elasticity, pushing the block 10 quickly into the slot 7, achieving mechanical locking. At this point, the sensor probe base... The base 3 is firmly fixed, and the probe electrical contact 6 is fully engaged with the host electrical contact 5, establishing a stable electrical connection. The torque sensing probe module 4 and the host communication module 2 complete the signal path connection. After the host is powered on, data is transmitted through the electrical contacts. The torque sensing probe module 4 can normally collect and send torque signals, and the equipment enters the working state. When it is necessary to replace or maintain the probe, the operator simultaneously presses the pressing push rods 13 on both sides of the host housing 1. The push rods drive the push plate 12 to slide in the sliding hole 11, pushing the locking block 10 out of the slot 7. The second spring 14 is compressed. Once the locking block 10 is disengaged from the slot 7, the mechanical lock is released. At this time, the two third springs 15 above the host communication module 2 release potential energy, pushing the top block 16 upward, automatically popping the sensor probe base 3 out of the host housing 1 a distance for easy gripping. The operator gently pulls the popped-out sensor probe base 3 to completely remove it from the host housing 1, completing the quick disassembly.

[0052] It should be noted that the connection and use of the host communication module 1, torque sensing probe module 4, host electrical contact 5, and probe electrical contact 6 in this solution are all existing technologies and will not be elaborated on in this article.
