Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sensor technology, and in particular relates to a terminal detection unit of an on-board monitoring and diagnostic host. Background Technology
[0002] A vibration sensor is a device used to detect and measure the vibration parameters of an object (such as vibration velocity, acceleration, and displacement). It converts mechanical vibration signals into electrical signals for subsequent analysis, monitoring, and control. During the operation of electric locomotives, vibration sensors are needed to monitor their operating status to ensure stable operation.
[0003] When installing existing vibration sensors, a stud is usually fixed at the front end of the sensor, and a threaded hole is made on the object being measured. The vibration sensor is installed by connecting the stud to the threaded hole. However, in use, the stud and the threaded hole are prone to loosening under vibration force. Once loosened, the vibration sensor cannot accurately detect the vibration of the object being measured. In severe cases, it may even cause the vibration sensor to fall off and be damaged.
[0004] Therefore, it is necessary to improve the terminal detection unit of the existing vehicle monitoring and diagnostic host. Utility Model Content
[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a terminal detection unit for an on-board monitoring and diagnostic host, which improves the installation firmness of vibration sensors.
[0006] To achieve the above objectives, the specific technical solution of the terminal detection unit of the vehicle-mounted monitoring and diagnostic host of this utility model is as follows:
[0007] A terminal detection unit for an on-board monitoring and diagnostic host includes a sensor body, with a mounting stud coaxially fixed to the front end face of the body, and further includes:
[0008] An abutment block is slidably disposed on the main body along the axial direction of the main body and is used to press against the object being tested;
[0009] A conical adjusting member, the height of which is perpendicular to the axis of the main body, the end of which abuts against the side of the adjusting member, and the adjusting member moving along its own height direction to control the distance by which the abutment block slides along the axial direction of the main body;
[0010] A locking mechanism is provided on the main body for locking the adjusting member.
[0011] Preferably, at least three abutment blocks are provided, and each abutment block is equally spaced around the axis of the main body.
[0012] Preferably, the side of the main body is provided with a sliding groove along its own axial direction, and one end of the sliding groove near the mounting stud is connected to the outside, and the abutment block is slidably engaged with the sliding groove.
[0013] Preferably, an adjusting stud is fixedly connected to the bottom surface of the slide along the radial direction of the main body, and the adjusting member has a threaded hole that is threadedly connected to the adjusting stud, and the axis of the threaded hole coincides with the height of the adjusting member.
[0014] Preferably, the end face of the abutment block near the adjusting member is an inclined surface.
[0015] Preferably, the bottom surface of the adjusting member is hinged with a handle, and the handle and the hinge axis of the adjusting member are perpendicular to the height of the adjusting member.
[0016] Preferably, the locking mechanism includes a positioning sleeve coaxially sleeved on the outer periphery of the main body, and the inner wall of the positioning sleeve is provided with a limiting groove for the handle to enter.

[0018] Preferably, the front end of the main body is also provided with a magnetic base, and the magnetic base has a threaded blind hole that is threadedly connected to the mounting stud.
[0019] The terminal detection unit of the vehicle-mounted monitoring and diagnostic host of this utility model has the following advantages: After the vibration sensor is installed, it is fixed by the abutment block against the object being tested, reducing the probability of the vibration sensor loosening and improving the detection accuracy of the vibration sensor; the position of the abutment block can be adjusted by the adjusting component, so that the abutment block can abut against the uneven surface of the object being tested, improving the fixing effect of the sensor; the locking mechanism is set to fix the adjusting component and prevent the adjusting component from loosening, thereby improving the overall installation firmness of the vibration sensor and improving the detection accuracy of the vibration sensor.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0028] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the vibration sensor and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.
[0029] like Figure 2 As shown, a terminal detection unit of an on-board monitoring and diagnostic host includes a sensor body 1, with a mounting stud 101 coaxially fixed to the front end face of the body 1, and an abutment block 6 slidably disposed on the body 1 along the axial direction for pressing against the object to be measured; a conical adjusting member 5, the height of which is perpendicular to the axis of the body 1, the end of which abuts against the side of the adjusting member 5, and the adjusting member 5 moving along its own height to control the distance the abutment block 6 slides along the axial direction of the body 1; and a locking mechanism disposed on the body 1 for locking the adjusting member 5.
[0030] The aforementioned vibration sensor is suitable for electric locomotives and is used to monitor the vibration of various components during locomotive operation to ensure the safe operation of the locomotive. When using the vibration sensor, a threaded mounting hole is made on the surface of the object being measured. The mounting stud 101 is screwed into the threaded mounting hole and tightened for initial securing. Then, adjustment is achieved through the adjusting component 5. The side of the adjusting component 5 controls the movement of the abutment block 6 along the axial direction of the main body 1, adjusting the position of the abutment block 6 so that its front end presses against the object being measured, thereby providing auxiliary support to the main body 1, improving the stability of the vibration sensor installation, and thus improving the detection accuracy of the vibration sensor. Finally, a locking mechanism locks the adjusting component 5 to prevent it from loosening due to locomotive vibration during subsequent use, effectively ensuring the stability of the adjusting component 5 and the abutment block 6, effectively preventing the vibration sensor from loosening or falling off, and improving the detection accuracy of the vibration sensor.
[0031] Further improvements include, for example Figure 2 As shown, at least three abutment blocks 6 are provided, and each abutment block 6 is distributed at equal intervals around the axis of the main body 1.
[0032] Specifically, the three abutment blocks 6 provide multi-point support from three positions, balancing the forces on the main body 1 and ensuring it is perpendicular to the axis of the main body 1, thus improving the stability of the main body 1 installation. Furthermore, the three abutment blocks 6 are independently controlled and adjusted by the adjusting component 5. When the surface of the object being tested is uneven, the position of the abutment blocks 6 can be adjusted to ensure that each abutment block 6 is in close contact with the object being tested, further enhancing the firmness of the vibration sensor installation and preventing it from loosening.
[0033] Further improvements include, for example Figure 3 As shown, a sliding groove 103 is provided on the side of the main body 1 along its own axial direction. One end of the sliding groove 103 near the mounting stud 101 is connected to the outside, and the abutment block 6 slides in cooperation with the sliding groove 103.
[0034] Specifically, the slide 103 is a T-shaped groove or a dovetail groove, which can prevent the abutment block 6 from falling out of the slide 103, improve the firmness of the abutment block 6 installation, and thus improve the firmness of the vibration sensor installation.
[0035] Further improvements include, for example Figure 3 and 6 As shown, an adjusting stud 102 is fixedly connected to the bottom surface of the slide groove 103 along the radial direction of the main body 1. The adjusting component 5 has a threaded hole 501 that is threadedly connected to the adjusting stud 102. The axis of the threaded hole 501 coincides with the height of the adjusting component 5.
[0036] Specifically, by turning the adjusting member 5, it moves along the direction of the adjusting stud 102. Since the adjusting member 5 is a conical structure, during its movement, the end of the abutment block 6 contacts the parts with different outer diameters of the adjusting member 5. Thus, the adjusting member 5 can push the abutment block 6 to move along the axial direction of the main body 1, thereby adjusting the position of the abutment block 6.
[0037] Further improvements include, for example Figure 5 As shown, the end face of the abutment block 6 near the adjusting member 5 is an inclined surface 601.
[0038] Specifically, the inclined surface on the abutment block 6 contacts the side of the adjusting component 5, which increases the contact area between the two, thereby reducing the pressure between them, reducing wear, and extending the service life of the equipment.
[0039] Further improvements include, for example Figure 6 As shown, a handle 4 is hinged to the bottom surface of the adjusting member 5, and the hinge axis of the handle 4 and the adjusting member 5 is perpendicular to the height of the adjusting member 5.
[0040] Specifically, the handle 4 is designed so that the adjustment component 5 can be rotated without the need for additional tools, thereby improving the ease of operation of the adjustment component 5; the handle 4 is hinged to the adjustment component 5, so that after adjustment, the handle 4 can be attached to the side of the main body 1, thereby retracting the handle 4, reducing the space occupied by the handle 4, and improving the ease of use of the vibration sensor.
[0041] Further improvements include, for example Figure 4 As shown, the locking mechanism includes a positioning sleeve 2 coaxially sleeved on the outer periphery of the main body 1, and the inner wall of the positioning sleeve 2 is provided with a limiting groove 201 for the handle 4 to enter.
[0042] Specifically, the positioning sleeve 2 slides along the axial direction of the main body 1. After the adjusting component 5 is adjusted to the correct position, the handle 4 is folded up, and the extension direction of the handle 4 is aligned with the extension direction of the limiting groove 201, both aligned with the axial direction of the main body 1. Thus, after the handle 4 is folded, the sliding positioning sleeve 2 can cover the abutment block 6, the adjusting component 5, and the handle 4, thereby protecting each component and preventing corrosion during long-term use, and facilitating subsequent disassembly and assembly of the vibration sensor. After the handle 4 is retracted into the limiting groove 201, the limiting groove 201 can restrict the position of the handle 4, thereby preventing the adjusting component 5 from rotating, and ultimately achieving the positioning of the abutment block 6, making the vibration sensor less prone to loosening or falling off in a vibration environment, thus improving its detection accuracy.
[0043] Further improvements include, for example Figure 4 As shown, both ends of the positioning sleeve 2 are circumferentially provided with sealing rings 202.
[0044] Specifically, the sealing ring 202 can improve the sealing effect between the positioning sleeve 2 and the object being measured and the main body 1, thereby improving the sealing effect of the positioning sleeve 2 on the detail block 6 and the adjustment component 5, slowing down the corrosion rate of each component, and extending the service life of the vibration sensor.
[0045] Further improvements include, for example Figure 1 As shown, the front end of the main body 1 is also provided with a magnetic seat 3, and the magnetic seat 3 has a threaded blind hole that is threadedly connected to the mounting stud 101.
[0046] In areas where it is inconvenient to drill holes, a magnetic base 3 can be used to attach the sensor to the magnetic base 3. Then, the mounting stud 101 is screwed into the magnetic base 3 to fix the main body 1 and the magnetic base 3 together, thereby improving the ease of installation of the vibration sensor. At the same time, the abutting block 6 abuts against the magnetic base 3, thereby improving the firmness of the connection between the magnetic base 3 and the main body 1 and preventing loosening between the two, so as to ensure the detection accuracy of the vibration sensor.
