Description

Technical Field

[0001] This utility model relates to the field of signal measurement device technology, specifically a handheld signal measurement device. Background Technology

[0002] With the rapid development of electronic information technology, many industries have increasingly higher requirements for time synchronization accuracy. Especially in fields such as ship information systems, aerospace, communications, power, transportation, and finance, accurate time signals are essential for the normal operation of various electronic devices. Time errors at the millisecond or even microsecond level can cause system malfunctions and result in irreparable losses.

[0003] Currently, most equipment relies on operators holding the measuring instrument by hand for extended periods. Prolonged operation can easily lead to arm fatigue and soreness, making it difficult to maintain a stable measuring posture. This not only affects measurement accuracy but also frequently causes the measuring instrument to slip and fall, resulting in instrument damage or data interruption. Therefore, we propose a handheld signal measuring device. Utility Model Content

[0004] The purpose of this utility model is to provide a handheld signal measuring device to solve the problem mentioned in the background art that most current equipment relies on the operator to hold the measuring instrument throughout the entire process. Long-term operation can easily lead to arm fatigue and soreness, making it difficult to maintain a stable measuring posture. This not only affects the measurement accuracy, but also often causes the measuring instrument to be accidentally dropped due to hand slippage, resulting in instrument damage or data interruption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a handheld signal measuring device, comprising: a fixed arm sleeve, a Velcro assembly fixedly connected to the side surface of the fixed arm sleeve, an adjustment assembly provided on the upper surface of the fixed arm sleeve, a positioning assembly provided on the upper surface of the adjustment assembly, and a measuring instrument movably connected to the upper surface of the positioning assembly. The positioning assembly includes a support plate, with outer protective plates fixedly connected to both ends of the upper surface of the support plate. A double-ended screw is movably connected through the left and right ends of the outer protective plate. A rotating handle is fixedly connected to the outer surface of the double-ended screw. A sliding seat is movably connected to the outer surface of the double-ended screw. A clamping plate is fixedly connected to the upper surface of the sliding seat. An anti-slip pad is fixedly connected to the outer surface of the clamping plate. Two sets of sliding seats are symmetrically arranged on the outer surface of the double-ended screw. A guide block is fixedly connected to the side surface of the sliding seat. A guide rod is movably connected to the front and rear ends of the guide block.

[0006] The guide rod is movably connected to a support base at its center, and the support base is fixedly connected to the upper surface of the support plate.

[0007] The support base has a protective pad fixedly connected to its side surface. The support base is symmetrically fixedly connected to both sides of the protective pad in two sets. The measuring instrument is movably connected to the upper surface of the protective pad.

[0008] The adjustment assembly includes a connecting plate, which is fixedly connected to the upper surface of the fixed arm sleeve. A rotating seat is fixedly connected to the upper surface of the connecting plate. A rotating shaft is fixedly connected to the top center of the rotating seat. An adjustment frame is movably connected to the outer surface of the rotating shaft.

[0009] The adjusting frame is movably connected to an adjusting seat at the end away from the rotating shaft. A V-shaped bracket is fixedly connected to the side surface of the adjusting seat. A fixing plate is fixedly connected to the upper surface of the V-shaped bracket. The fixing plate is fixedly connected to the bottom of the support plate.

[0010] The fixed arm sleeve has two parts, which are fixedly connected to both ends of the Velcro assembly.

[0011] This utility model has at least the following beneficial effects: 1. In use, this utility model utilizes a double-headed screw and anti-slip pads. The positioning component is supported by a base frame built on a support plate. The double-headed screws between the outer protective plates pass through two sets of sliding seats, which are slidably connected to the guide rods and limited by the support seats. When the handle is rotated, the double-headed screws drive the sliding seats to simultaneously tighten the clamping plates. The anti-slip pads tightly adhere to the measuring instrument's outer shell from both sides, and the bottom protective pad provides support. This device effectively solves the fatigue caused by holding the instrument for extended periods during traditional handheld measurements, preventing the measuring instrument from slipping due to hand soreness. Even if the operator's arm shakes or there is an accidental collision, the friction of the anti-slip pads and the mechanical locking of the clamping structure ensure that the instrument will not fall off. Compared to traditional handheld methods, this effectively reduces the risk of damage and allows operators to complete long-term measurement tasks without continuous force.

[0012] 2. In use, this utility model utilizes a rotating shaft and a V-shaped bracket. The adjusting component is connected to the fixed arm sleeve via a connecting plate. The rotating shaft passes through the top of the rotating seat of the component and is movably connected to the adjusting frame, allowing the operator to easily rotate the adjusting frame to change the tilt angle. Simultaneously, the adjusting seat at the other end of the adjusting frame can rotate, driving the V-shaped bracket and the fixed plate to adjust their positions. This dual-movable connection design allows the measuring instrument to be flexibly adjusted in multiple directions, easily handling measurement scenarios in confined spaces or at special angles, effectively solving the problems of fixed angles and difficult operation inherent in traditional devices.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a handheld signal measuring device, including: a fixed arm sleeve 1, a Velcro assembly 2 fixedly connected to the side surface of the fixed arm sleeve 1, an adjustment assembly 3 provided on the upper surface of the fixed arm sleeve 1, a positioning assembly 4 provided on the upper surface of the adjustment assembly 3, and a measuring instrument 5 movably connected to the upper surface of the positioning assembly 4.

[0017] In use, the positioning component 4, with its double-ended screw 44 and anti-slip pad 47, forms a basic frame on the support plate 41. The double-ended screw 44 between the outer protective plates 42 passes through two sets of sliding seats 45, which are slidably connected to the guide rod 49 and limited by the support seat 410. When the handle 43 is rotated, the double-ended screw 44 drives the sliding seats 45 to tighten the clamping plate 46 simultaneously. The anti-slip pad 47 fits tightly against the outer shell of the measuring instrument 5 from both sides, and the bottom protective pad 411 provides support. This device effectively solves the fatigue caused by holding the instrument for a long time during traditional handheld measurement and avoids the problem of the measuring instrument 5 slipping off due to hand soreness. Even if the operator's arm shakes or there is an accidental collision, the friction of the anti-slip pad 47 and the mechanical locking of the clamping structure ensure that the instrument will not fall off. Compared with the traditional handheld method, this effectively reduces the risk of damage and allows the operator to complete long-term measurement work without continuous force.

[0018] The positioning component 4 includes a support plate 41. The upper surface of the support plate 41 is fixedly connected to both ends of an outer protective plate 42. The left and right ends of the outer protective plate 42 are movably connected to a double-ended screw 44. The outer surface of the double-ended screw 44 is fixedly connected to a rotating handle 43. The outer surface of the double-ended screw 44 is movably connected to a sliding seat 45. The upper surface of the sliding seat 45 is fixedly connected to a clamping plate 46. The outer surface of the clamping plate 46 is fixedly connected to an anti-slip pad 47. The sliding seats 45 are symmetrically arranged in two sets on the outer surface of the double-ended screw 44. The side surface of the sliding seat 45 is fixedly connected to a guide block 48. The front and rear ends of the guide block 48 are connected to a guide rod 49.

[0019] A support base 410 is movably connected at the center of the guide rod 49, and the support base 410 is fixedly connected to the upper surface of the support plate 41.

[0020] A protective pad 411 is fixedly connected to the side surface of the support base 410. The support base 410 is symmetrically fixedly connected to both sides of the protective pad 411 in two sets. The measuring instrument 5 is movably connected to the upper surface of the protective pad 411.

[0021] The adjustment assembly 3 includes a connecting plate 31, which is fixedly connected to the upper surface of the fixed arm sleeve 1. A rotating seat 32 is fixedly connected to the upper surface of the connecting plate 31. A rotating shaft 33 is fixedly connected to the top center of the rotating seat 32. An adjustment frame 34 is movably connected to the outer surface of the rotating shaft 33.

[0022] An adjusting seat 35 is movably connected to one end of the adjusting frame 34 away from the rotating shaft 33. A V-shaped bracket 36 is fixedly connected to the side surface of the adjusting seat 35. A fixing plate 37 is fixedly connected to the upper surface of the V-shaped bracket 36. The fixing plate 37 is fixedly connected to the bottom of the support plate 41.

[0023] When using this handheld signal measuring device, firstly, the fixed arm sleeve 1 is tightly fitted to the operator's arm using the Velcro assembly 2. The adjustable nature of the Velcro assembly 2 allows it to adapt to different arm sizes, ensuring stable wear of the device. Subsequently, according to the measurement requirements, the angle and height of the measuring instrument 5 are adjusted using the adjustment assembly 3.

[0024] In the adjustment assembly 3, the connecting plate 31 is fixed to the fixed arm sleeve 1, the rotating shaft 33 passes through the top of the rotating seat 32 and is movably connected to the adjustment frame 34. The operator can rotate the adjustment frame 34 to change its tilt angle around the rotating shaft 33. The other end of the adjustment frame 34 is movably connected to the adjustment seat 35. By rotating the adjustment seat 35 in the end of the adjustment frame 34 away from the rotating shaft 33, the tilt angle between the V-shaped bracket 36, the fixed plate 37 and the adjustment frame 34 is driven, thereby accurately adjusting the spatial position of the positioning assembly 4 and the measuring instrument 5.

[0025] When it is necessary to fix the measuring instrument 5, the operator turns the handle 43, which drives the double-ended screw 44 to rotate. Since the threads at both ends of the double-ended screw 44 turn in opposite directions, the two sets of sliding seats 45 sleeved on its outer surface will move towards or away from each other under the threaded transmission. The side surface of the sliding seat 45 is slidably connected to the guide rod 49, and the guide rod 49 is fixed to the support plate 41 by the support seat 410, ensuring that the sliding seat 45 can only slide smoothly in a straight line and avoids deviation.

[0026] As the sliding seat 45 moves, the clamping plate 46 fixed above it moves closer to or further away. The anti-slip pad 47 on the outer surface of the clamping plate 46 increases friction, tightly adhering to the housing of the measuring instrument 5 and firmly clamping it. Simultaneously, the protective pad 411 on the side surface of the support seat 410 supports the measuring instrument 5 from the bottom, preventing damage due to uneven force during clamping, thus achieving multi-angle, stable, and reliable fixation of the measuring instrument 5. The entire device, through the coordinated operation of its components, allows operators to flexibly adjust the position and angle of the measuring instrument 5, meeting the signal measurement needs in complex environments, freeing up their hands while improving measurement efficiency and accuracy.
