Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic measurement, in particular to a tightening bolt knob type ultrasonic probe. Background Art
[0002] As a connecting fastener in a specific scenario, it is very important to strictly control the tightening stress (or bolt preload) of the double-headed tension bolt. If the stress is too small, the structure will become loose; if the stress is too large, the bolt will break. For a certain M12 double-headed tension bolt with a standard pitch of 1.25mm, there is an inward opening design on its head. During ultrasonic stress measurement, due to the small contact surface and the opening on the contact surface, conventional ultrasonic probes are difficult to install and fix, and ultrasonic signals cannot be effectively excited and received, which will have a serious impact on the measurement of preload. At present, some ultrasonic probes can be adsorbed on magnetic materials through magnetic rings, and the central probe is in contact with the bolt to perform ultrasonic measurement of preload, which has certain limitations; non-magnetic materials are fixed by adhesives, which is not convenient for installation and disassembly and has low flexibility.
[0003] Therefore, we made improvements on this and proposed a tension bolt knob type ultrasonic probe. Utility Model Content
[0004] In order to solve the problem that the existing ultrasonic probe is inconvenient to fix and install, the utility model provides a tightening bolt knob type ultrasonic probe.
[0005] The utility model is achieved in this way:
[0006] A tension bolt knob type ultrasonic probe comprises an ultrasonic probe and a connected part, wherein the bottom end of the ultrasonic probe is threadedly connected with a stud tension bolt, one end of the stud tension bolt is threadedly connected with a nut, the nut is fixed to the top end of the connected part, and the bottom end of the stud tension bolt extends to the interior of the connected part, a sensor is installed inside the ultrasonic probe, the bottom end of the sensor is in contact with the top end of the stud tension bolt, and a connecting socket is inserted into the top end of the ultrasonic probe.
[0007] Furthermore, an anti-skid component is provided on the outer wall of the ultrasonic probe, and the anti-skid component includes a spline sleeve and a spacer ring, and the bottom end of the spline sleeve is sleeved with the spacer ring.
[0008] The beneficial effect of adopting the above further solution is that, by using the spacer ring as a set, it is possible to distinguish the positions of the spline sleeve and the ultrasonic probe, thereby making it easier for the assembler to choose to hold them.
[0009] Furthermore, the spline sleeve and the spacer ring are flush with the outer wall of the ultrasonic probe.
[0010] The beneficial effect of adopting the above further solution is that, through the positional relationship between the spline sleeve, the spacer ring and the ultrasonic probe, the outer wall of the ultrasonic probe is kept at the same level.
[0011] Furthermore, the ultrasonic probe includes a probe body and a threaded hole. The bottom end of the probe body is provided with a threaded hole, and the inside of the threaded hole is engaged with the top end of the stud tensioning bolt.
[0012] The beneficial effect of adopting the above further solution is that, through the provision of the threaded hole, the ultrasonic probe has a position space for docking with the double-headed tensioning bolt.
[0013] Furthermore, the double-headed tensioning bolt comprises a bolt body, a sliding ring and a rubber gasket. The outer wall of the bolt body is slidably connected to the sliding ring, and the outer wall of the sliding ring is sleeved with the rubber gasket.
[0014] The beneficial effect of adopting the above further solution is that, through the sliding connection of the slip ring, the slip ring can drive the rubber gasket to move to any position.
[0015] Furthermore, the thickness of the rubber gasket is greater than the thickness of the slip ring.
[0016] The beneficial effect of adopting the above further solution is that, through the thickness difference between the rubber gasket and the slip ring, the rubber gasket can maintain the function of a buffer pad between the ultrasonic probe and the nut.
[0017] Furthermore, the connecting socket includes an insert rod, a clamping ring and a limiting ring. The limiting ring is sleeved on the outer wall of the insert rod, and the bottom end of the limiting ring fits with the top end of the ultrasonic probe.
[0018] The beneficial effect of adopting the above further solution is that, by using the limiting ring set, the insertion rod can be restricted to a specified area.
[0019] Furthermore, the top end of the insertion rod extends to the outside of the ultrasonic probe and is provided with a clamping ring.
[0020] The beneficial effect of adopting the above further solution is that, through the provision of the clamping ring, it is convenient to connect the socket and the external device for fixed docking.
[0021] The beneficial effects of the utility model are: the knob-type ultrasonic probe is small in size, simple in structure, easy to install, highly reliable and low in cost; the knob-type fixing structure can effectively match the threaded structure of the tightening bolt head, while ensuring close contact between the sensor and the bolt surface; the bolt material does not require magnetism and does not require adhesive fixation; it is easy to install and flexible to disassemble; therefore, it has good practicality, is easy to promote and apply, and has great practical value.
