Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1

[0032] Please see Figure 1-8 This is the first embodiment of the present invention, which provides an oscilloscope probe calibration device, comprising:

[0033] The connecting mechanism 100 includes an oscilloscope probe body 101, a flip cover assembly 102 disposed on the outside of the oscilloscope probe body 101, a pull rod 103 disposed on one side of the flip cover assembly 102, and an adjustment assembly 104 movably installed on the other end of the pull rod 103.

[0034] The display and control mechanism 200 includes a tuning panel 201 embedded in the groove of the oscilloscope probe body 101, a compensation capacitor module 202 electrically fixed to one end of the tuning panel 201, and a plug slot 203 electrically fixed to the end of the compensation capacitor module 202.

[0035] Specifically, the flip cover assembly 102 includes a protective cover 102a that is hinged and installed in the groove of the oscilloscope probe body 101. An opening groove 102b is provided on one side of the protective cover 102a, and two limiting grooves 102c are provided in a symmetrical structure in the opening groove 102b.

[0036] Furthermore, by adding a limiting groove 102c inside the opening groove 102b, the user can, while opening the protective cover 102a, have the traction rod 103, which is fitted inside the opening groove 102b, slide along the trajectory of the limiting groove 102c in advance as the protective cover 102a flips open and closes. When the traction rod 103 slides to the extreme of the limiting groove 102c, it can then pull the movable connecting limiting adjustment component 104 to perform a telescopic action. This allows the telescopic action of the adjustment component 104 to respond to the opening and closing action of the protective cover 102a, thereby realizing the waveform control of the compensation capacitor module 202 by the adjustment component 104.

[0037] Specifically, a notch 102e is provided on one side of the protective cover 102a, and an elastic pressure plate 102f is engaged and limited on one side of the notch 102e. The elastic pressure plate 102f is fixedly connected in the groove of the oscilloscope probe body 101, and the notch 102e and the limiting groove 102c are arranged in opposite directions, and the two limiting grooves 102c are slidably adapted to the traction rod 103.

[0038] Furthermore, by using the elastic pressure plate 102f to abut and limit the notch 102e, it can be ensured that after the protective cover 102a is closed, it can be stably closed and stored in the groove of the oscilloscope probe body 101 under the abutment of the elastic pressure plate 102f, ensuring that the oscilloscope probe body 101 is clean and beautiful to use. The notch 102e and the limiting groove 102c are set in opposite directions, which can ensure that under the abutment and limitation of the elastic pressure plate 102f on the notch 102e, the traction rod 103 can be flipped and stably stored in the opening groove 102b.

[0039] Specifically, the traction rod 103 has two roller sleeves 103a rotatably connected to one end of its shaft in a symmetrical structure. The two roller sleeves 103a have multiple through holes 103b in an annular structure with equal spacing. A paraffin rod 103c is embedded in the through hole 103b. The other end of the traction rod 103 is rotatably connected to the adjustment component 104 through a ball joint structure.

[0040] Furthermore, the rolling friction contact between the roller sleeve 103a and the limiting groove 102c effectively reduces the smoothness of the displacement adjustment response of the traction rod 103, making the extension adjustment of the traction rod 103 faster. When the roller sleeve 103a and the limiting groove 102c are in rolling friction contact, the paraffin rod 103c embedded in the through hole 103b on the outside of the roller sleeve 103a can rub against the limiting groove 102c, thereby causing paraffin powder to fall and lubricate the limiting groove 102c, further improving the smoothness of the sliding contact between the traction rod 103 and the limiting groove 102c.

[0041] Specifically, the adjusting knob 104b includes a prism rod 104d inserted inside the set screw 104c. One end of the prism rod 104d has a slot 104e that can be inserted and adapted to the mating post 104a. A limiting bolt 104f is threadedly connected to one side of the slot 104e. The limiting bolt 104f can be clearance-fitted with the annular groove at one end of the mating post 104a. A rotating block that can be inserted and adapted to the prism rod 104d is sleeved on the outside of the mating post 104a.

[0042] Furthermore, the opening and closing of the protective cover 102a causes the traction rod 103 to shift, thereby pulling the docking post 104a and causing the prism rod 104d to slide along the internal trajectory of the set screw 104c. This extends the length of the set screw 104c's rotation adjustment, allowing the set screw 104c to rotate synchronously when the rotating block rotates, at the insertion connection limit of the prism rod 104d. This enables the set screw 104c to regulate the compensation capacitor module 202, ensuring quick and easy waveform calibration.

[0043] In summary, based on the design of the oscilloscope probe calibration device, the flip cover assembly 102 and the adjustment assembly 104 enable the extension and adjustment of the adjustment assembly 104 when the flip cover assembly 102 is opened and closed. This allows the extended adjustment assembly 104 to function as a screwdriver, enabling quick adjustment of the oscilloscope probe without the need for flipping adjustment tools, thus ensuring the flexibility of oscilloscope probe waveform calibration.

[0044] Example 2

[0045] Please see Figure 1 , Figure 3 and Figure 7 This is the second embodiment of the present invention, which provides an improved design for an oscilloscope probe calibration device.

[0046] Specifically, a nylon plug 104g is inserted and installed at one end of the set screw 104c, and the nylon plug 104g is in close contact with the compensation capacitor module 202.

[0047] Furthermore, by sealing one end of the set screw 104c with the nylon plug 104g, it can be ensured that the set screw 104c can stably push the compensation capacitor module 202 for displacement calibration under the screw adjustment, so as to achieve elastic contact and avoid damage to the compensation capacitor module 202 caused by rigid contact between the rotating set screw 104c and the compensation capacitor module 202.

[0048] Specifically, a rubber cover 202a is provided on one side of the compensation capacitor module 202. The rubber cover 202a is inserted into the insertion slot 203 and is connected and fixed to the oscilloscope probe body 101.

[0049] Furthermore, the rubber cap 202a can seal the plug-in slot 203, ensuring the safety of the plug-in slot 203 when it is not connected and stored.

[0050] During calibration, the user manually flips the protective cover 102a outward. As the notch 102e and the elastic pressure plate 102f disengage from the contact limit, the outwardly flipped protective cover 102a first makes sliding contact with the traction rod 103 stored in the opening slot 102b. When the protective cover 102a is rotated open to a certain angle, the traction rod 103, which is slidably connected to the opening slot 102b, makes contact limit with the extreme of the opening slot 102b, and is displaced and stretched as the protective cover 102a continues to flip.

[0051] When the protective cover 102a is flipped to the limit angle, the traction rod 103 that slides against it and is limited pulls the docking post 104a, causing the prism rod 104d to slide along the internal trajectory of the set screw 104c, thereby extending the length of the set screw 104c rotation adjustment.

[0052] Finally, manually adjust the rotating block to drive the spiral displacement of the set screw 104c, and push the compensation capacitor module 202 to move under the elastic resistance of the nylon plug 104g. Observe the waveform and adjust accordingly.
