Description

Technical Field

[0001] The utility model relates to the technical field of oscilloscopes, in particular to an elevation-angle oscilloscope. Background Art

[0002] An elevation oscilloscope is a special type of oscilloscope, which is usually used to measure high-frequency signals and pulse signals. Unlike traditional oscilloscopes, elevation oscilloscopes can capture and display short pulses and rapidly changing signals with higher time resolution. The name of this oscilloscope comes from the shape of its display screen, which is tilted upward, so that the details and short changes of the signal can be observed more clearly on the time axis. This design makes the elevation oscilloscope particularly suitable for observing transient signals such as pulses, spikes, and rapidly changing signals.

[0003] There are many existing technologies for oscilloscopes, such as:

[0004] Chinese patent publication number CN217156597U discloses an oscilloscope probe and an oscilloscope, which include a handle and a test pole. The handle includes a main body and a pressing part, and the pressing part is pressably arranged on the main body; the test pole includes a positive pole and a ground pole, and the positive pole and the ground pole are arranged at intervals on the main body, and when the pressing part is pressed, at least one of the positive pole and the ground pole can be close to the other. The technical solution of the utility model can improve the convenience of the test process and ensure the accuracy of the test results.

[0005] When using an existing oscilloscope, in order to better observe the pulse signal on the lower display screen, the display screen is usually tilted backward at a certain angle. However, as the number of uses increases, the display screen shaft and the connection will become loose, making it difficult to maintain a certain angle for a long time. In addition, dust falls on the oscilloscope, which will affect the accuracy of observing the pulse signal on the one hand, and the dust itself will affect the service life of the electronic instrument on the other hand.

[0006] In view of this, we propose an elevation-angle oscilloscope, which fixes the oscilloscope body in its original position after being rotated to a certain angle through a limit component, and can prevent it from rotating due to looseness of the shaft and the connection. A protective component is used to prevent dust from falling onto the display screen when the oscilloscope body is not in use. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0026] See also Figure 1-Figure 6 As shown, this embodiment provides an elevation-type oscilloscope, including a mounting assembly 10, the mounting assembly 10 includes a mounting seat 11, support arms 12 are provided at two ends of the top of the mounting seat 11 that are far away from each other, a pair of limit bolts 13 are provided at the top of the mounting seat 11 between the two support arms 12, a limit assembly 20 is rotatably connected between the two limit bolts 13, the limit assembly 20 is used to keep the oscilloscope at a certain elevation angle to prevent the oscilloscope from rotating, and a protective assembly 30 is provided between the two support arms 12, the protective assembly 30 is used to prevent dust from falling onto the display screen of the oscilloscope.

[0027] Working principle: When the elevation-angle oscilloscope provided by the utility model is used, the limit component 20 is used to keep the oscilloscope at a certain elevation angle to prevent the oscilloscope from rotating, and the protective component 30 is used to prevent dust from falling onto the display screen of the oscilloscope. Specifically, when in use, the motor 34 drives the gear 33 to rotate, thereby driving the racks 32 on the two protective covers 31 to move in a direction away from each other.

[0028] In order to keep the oscilloscope at a certain elevation angle and prevent the oscilloscope from rotating, the limit assembly 20 includes an oscilloscope body 21 rotatably connected between two limit bolts 13, a ratchet 22 is coaxially connected to the rotating shaft of the oscilloscope body 21, a fixed frame 23 is arranged on the periphery of the ratchet 22, the fixed frame 23 is fixedly connected to the inner wall of the support arm 12, a plurality of ratchet pawls 24 are arranged between the fixed frame 23 and the ratchet 22, the plurality of ratchet pawls 24 are rotatably connected to the fixed frame 23, and the ends of the plurality of ratchet pawls 24 away from the fixed frame 23 are all engaged with the periphery of the ratchet 22; the ratchet 22 is fixed by a central axis, and its outer ring has a series of ratchet teeth arranged evenly at intervals. When an external force acts on the ratchet 22, the ratchet teeth will start to rotate under the action of torque. The special shape of the ratchet teeth makes them rotate only in one direction and are blocked in the other direction. When the ratchet 22 rotates, they will pass through the ratchet teeth adjacent to it one by one. This transmission mode effectively transmits the input torque to the next ratchet tooth to realize the transmission of power. This transmission mode of transmitting only one ratchet tooth at a time enables the ratchet 22 to have higher accuracy and stability when transmitting power.

[0029] Taking into account the need to remove the fixation of the oscilloscope body 21, a torsion spring 25 is provided on the periphery of the rotating shaft of the ratchet 22, a fixed arm 26 is provided on the periphery of the torsion spring 25, the side of the pawl 24 away from the ratchet 22 is fixedly connected to a spring plate 27, the end of the spring plate 27 away from the pawl 24 is slidably connected to the fixed frame 23, the inner circle of the torsion spring 25 is fixedly connected to the outer circle of the rotating shaft of the pawl 24, and the outer circle of the torsion spring 25 is fixedly connected to the inner circle of the fixed arm 26; the spring plate 27 is pulled to drive the pawl 24 away from the ratchet 22, thereby removing the restriction of the pawl 24 on the outer teeth of the ratchet 22.

[0030] In order to prevent dust from falling onto the display screen of the oscilloscope, the protective component 30 includes a protective cover 31 slidably connected to the side wall of the support arm 12, a rack 32 is fixedly connected to the side wall of the protective cover 31, a gear 33 is meshed on one side of the rack 32, a motor 34 is provided at the bottom of the gear 33, and the output shaft of the motor 34 is coaxially connected to the gear 33; the material of the protective cover 31 is high-silicon glass; when reading normally, the oscilloscope body 21 is observed through the protective cover 31 made of high-silicon glass, and when the settings on the oscilloscope body 21 need to be adjusted, the power is turned on to drive the gear 33 to rotate through the motor 34, thereby driving the racks 32 on the two protective covers 31 to move away from each other.

[0031] When the elevation oscilloscope provided in the utility model is used, the limit assembly 20 is set to keep the oscilloscope at a certain elevation angle to prevent the oscilloscope from rotating. Specifically, the ratchet 22 is fixed by a central axis, and its outer ring has a series of ratchet teeth arranged evenly at intervals. When an external force acts on the ratchet 22, the ratchet teeth will start to rotate due to the torque. The special shape of the ratchet teeth makes them rotate only in one direction and are blocked in the other direction. When the ratchet 22 rotates, they will pass through the ratchet teeth adjacent to it one by one. This transmission mode effectively transmits the input torque to the next ratchet tooth to achieve power transmission. This transmission method of transmitting only one ratchet tooth at a time makes the ratchet 22 have higher accuracy and stability when transmitting power; in addition, pulling the spring piece 27 drives the pawl 24 to move it away from the ratchet 22, removing the restriction of the pawl 24 on the outer teeth of the ratchet 22; the protective component 30 is used to prevent dust from falling onto the display screen of the oscilloscope, specifically, the material of the protective cover 31 is high-silicon glass; when reading normally, the oscilloscope body 21 is observed through the protective cover 31 made of high-silicon glass, and when the settings on the oscilloscope body 21 need to be adjusted, the power is turned on to drive the gear 33 to rotate through the motor 34, thereby driving the racks 32 on the two protective covers 31 to move in a direction away from each other.
