Description

Technical Field

[0001] This utility model relates to electrical testing technology, specifically to a portable electrical equipment testing device. Background Technology

[0002] Chinese utility model patent CN208537583U discloses a portable electrical equipment testing device. This device uses a fixed frame to fix the front and rear ends of the testing instrument, and a connecting rod is provided between the fixed frames. The protective sleeve on the connecting rod allows for easy carrying, replacing the existing box-type structure. It is convenient to carry and can be used directly. The fixed frame is connected to the telescopic plate slot, thereby realizing the adjustment of the fixed width, which is suitable for testing instruments of different specifications. Furthermore, a movable positioning plate is installed on the outside of the fixed frame. While not hindering the fixed installation of the testing instrument, the protective pad attached to the positioning plate can effectively protect the testing instrument and has a good anti-collision function. The overall structure is simple and highly practical.

[0003] With the rapid development of electrical equipment testing technology, portable testing devices are gradually evolving towards functional integration and miniaturization. Existing devices typically integrate the display screen, operation buttons, and testing circuitry into a compact housing, facilitating portability and on-site testing. However, such devices have significant drawbacks in practical applications: First, the testing process is time-consuming (such as insulation testing of high-voltage equipment and multi-circuit parameter analysis), requiring operators to hold the device with one hand for extended periods, leading to continuous stress on hand muscles and causing fatigue and soreness. Second, traditional grip designs are simplistic, relying solely on the side or back of the housing for gripping, lacking ergonomic multi-angle adjustment functions and making it difficult to adapt to different operating postures (such as standing and holding the device high, or observing from a tilted table). Third, the device lacks stability when placed, easily sliding and tipping over during temporary placement, affecting the efficiency of data reading. Utility Model Content

[0004] The purpose of this invention is to provide a portable electrical equipment testing device to solve the problems of existing portable testing devices, which have high integration but simple grip design, lack of ergonomic adjustment, easy hand fatigue during long-term operation, and insufficient placement stability, thus affecting data reading efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable electrical equipment testing device, comprising a testing device body, the testing device body including a shell, a display screen, a testing circuit and operation buttons disposed on the shell, the testing circuit being used to test various parameters of the electrical equipment, the display screen being used to display the testing results in real time, and also including two gripping parts, an angle positioning component and a reset elastic unit;

[0006] Two grips are symmetrically arranged on the back of the casing;

[0007] The grip has a rotating shaft fixedly installed at both the top and bottom ends;

[0008] An angle positioning component is disposed at one end of one of the rotating shafts, and the angle positioning component includes:

[0009] A cylindrical positioning component is provided on the outer shell. Multiple slots are evenly opened on the inner wall of the cylindrical positioning component. The outer wall of the rotating shaft on one side of the cylindrical positioning component is movably connected to the cylindrical positioning component, and the outer wall of the other rotating shaft is movably connected to the inner wall of the outer shell.

[0010] The snap-fit ​​part is provided on the rotating shaft on one side of the cylindrical positioning member, and the snap-fit ​​part can be inserted into one of the slots;

[0011] The reset elastic unit is located between one of the rotating shafts and the housing.

[0012] Furthermore, the reset elastic unit is a compression spring, which is sleeved on the outside of the rotating shaft on one side, and the two ends of the compression spring abut against the rotating shaft and the outer shell on one side, respectively.

[0013] Furthermore, the outer casing has holes for installing cylindrical positioning components, and the outer wall of the cylindrical positioning components is fixedly connected to the cylindrical positioning components.

[0014] Furthermore, the length direction of the slot is the same as the height direction of the cylindrical positioning element.

[0015] Furthermore, the grip is arranged in a U-shape.

[0016] Furthermore, the lower end of the grip is provided with a support portion that is set at an angle.

[0017] Furthermore, the outer casing is provided with a receiving groove for accommodating the gripping component.

[0018] Furthermore, the surface of the grip is covered with an anti-slip layer.

[0019] Compared with the prior art, the portable electrical equipment testing device provided by this utility model achieves multi-angle adjustment through symmetrically arranged gripping parts in conjunction with rotating shafts, slots and angle positioning components. It supports various gripping postures such as palm gripping, thumb hooking or back of hand insertion, effectively dispersing hand pressure. The locking part and the circumferential slot of the cylindrical positioning part engage to form a rigid lock, preventing accidental rotation during operation and ensuring testing stability. The reset elastic unit provides axial reset force, simplifying the angle adjustment operation, which can be completed with a pull, a turn and a release.

[0020] The inclined support at the lower end of the grip forms a support structure with the back of the outer shell, allowing the device to stand stably on the table, making it easy to check data during gap detection. The receiving slot precisely matches the contour of the grip, and the device surface is flat after storage, preventing protruding parts from snagging on clothing or causing collisions when stacked.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] Please see Figures 1 to 8 and Figure 10 A portable electrical equipment testing device includes a testing device body 100. The testing device body 100 includes a housing 101, a display screen 102 for real-time display of testing results, a testing circuit, and operation buttons 103 disposed on the housing 101. The testing circuit is used to detect various parameters of the electrical equipment. The testing circuit is a conventional technical module in the field of electrical equipment testing. Its function is to collect, analyze, and output key parameters of the electrical equipment under test through built-in sensors, signal processing units, and control chips. For example, voltage detection is based on the voltage divider principle. A high voltage (e.g., 1000V) is proportionally attenuated to a low voltage signal (e.g., 5V) through a series resistor network. The signal is then input to an MCU (microcontroller) for processing via an ADC (analog-to-digital converter). This is existing technology and will not be described in detail here.

[0036] It also includes two grips 200, an angle positioning assembly 400, and a reset elastic unit 500;

[0037] Two grips 200 are symmetrically arranged on the back of the housing 101;

[0038] The upper and lower ends of the grip 200 are both fixedly mounted with a rotating shaft 300;

[0039] An angle positioning component 400 is disposed at the end of one of the rotating shafts 300. The angle positioning component 400 includes a cylindrical positioning member 410 and a snap-fit ​​portion 430 disposed on the housing 101. A plurality of snap-fit ​​grooves 420 are evenly provided on the inner wall of the cylindrical positioning member 410. The outer wall of the rotating shaft 300 located on one side of the cylindrical positioning member 410 is movably connected to the cylindrical positioning member 410. The rotating shaft 300 located on one side of the cylindrical positioning member 410 can rotate relative to the cylindrical positioning member 410 and can move along the axial direction of the rotating shaft 300. The outer wall of the other rotating shaft 300 is movably connected to the inner wall of the housing 101. The other rotating shaft 300 can rotate relative to the housing 101 and can move along the axial direction of the rotating shaft 300.

[0040] The snap-fit ​​part 430 is provided on the rotating shaft 300 on one side of the cylindrical positioning member 410, and the snap-fit ​​part 430 can be inserted into one of the slots 420;

[0041] The reset elastic unit 500 is disposed between one of the rotating shafts 300 and the housing 101.

[0042] With the advancement of technology, existing electrical equipment testing instruments are becoming increasingly sophisticated in their functions and smaller in size, and often integrate components such as display devices. Figure 2 As shown, while designed for convenient testing, the existing portable electrical equipment testing devices are time-consuming, causing hand fatigue and pain after prolonged use.

[0043] To address this, this application provides a gripper 200 on the back of the housing 101. When using the gripper 200, pulling it along the axis of the rotating shaft 300 compresses the reset elastic unit 500, causing the gripper 200 to move the locking part 430 out of the slot 420 via the rotating shaft 300. At this time, the gripper 200 can be rotated under the limitation of the rotating shaft 300. After rotating the gripper 200 to a predetermined position, the locking part 430 is re-embedded into one of the slots 420 under the push of the reset elastic unit 500. The device cannot be rotated. Inspectors can use the inspection device body 100 for inspection by gripping the grip 200 or inserting their hand between the grip 200 and the outer shell 101. When the grip 200 is not in use, it is close to the outer shell 101 for easy carrying by inspectors. The locking part 430 and the circumferential groove 420 of the cylindrical positioning part 410 engage to form a rigid lock, preventing accidental rotation during operation and ensuring inspection stability. The reset elastic unit 500 provides axial reset force, simplifying the angle adjustment operation (it can be completed by pulling, turning and releasing).

[0044] Please see Figure 3 and Figure 5 In one embodiment of this utility model, the reset elastic unit 500 is a compression spring, which is sleeved on the outside of the rotating shaft 300 on one side, and the two ends of the compression spring abut against the rotating shaft 300 and the outer shell 101 on one side, respectively.

[0045] Specifically, by utilizing the linear deformation characteristics of the compression spring, a stable axial restoring force is provided to the rotating shaft 300, enabling the locking part 430 to be stably locked in the slot 420. By sleeved the compression spring on the outside of the rotating shaft 300 on one side, internal space is saved. At the same time, the compression spring is guided by the rotating shaft 300 and is not easily deflected, thus extending its service life.

[0046] Please see Figure 3 and Figure 4 In one embodiment of the present invention, the outer shell 101 is provided with a hole (not shown in the figure) for installing the cylindrical positioning member 410, and the outer side wall of the cylindrical positioning member 410 is fixedly connected to the cylindrical positioning member 410.

[0047] Specifically, the cylindrical positioning component 410 can be fixed by mechanical interference fit or welding to prevent it from loosening during frequent angle adjustments and to ensure the positional accuracy of the slot 420.

[0048] Please see Figure 8 In one embodiment of this utility model, the length direction of the slot 420 is the same as the height direction of the cylindrical positioning member 410;

[0049] Specifically, by setting the length direction of the slot 420 to be the same as the height direction of the cylindrical positioning member 410, so as to match the moving direction of the rotating shaft 300, the locking part 430 is subjected to uniform force when sliding into the slot 420, reducing lateral wear. Furthermore, the slots 420 can be spaced at equal angles (e.g., one slot 420 every 15°) to achieve effective positioning in stepless adjustment and avoid misalignment.

[0050] Please see Figure 6 In one embodiment of this utility model, the grip 200 is arranged in a U-shape;

[0051] Specifically, the grip 200 is arranged in a U-shape to form a semi-enclosed grip space, which is compatible with various postures such as palm gripping, finger hooking, and inserting the hand between the grip 200 and the outer shell 101, adapting to different hand shapes.

[0052] Please see Figure 9 In one embodiment of the present invention, the lower end of the grip 200 is provided with a support portion 210 that is inclined.

[0053] Specifically, by setting an inclined support part 210, the detection device body 100 can be supported and placed on the table in an inclined posture (such as when briefly placing the observation screen during detection). The support part 210 serves as a fulcrum and forms a support structure with the back of the outer shell 101, ensuring the stability of the device. Anti-slip textures or rubber pads can also be added to the bottom surface of the support part 210 to enhance its anti-slip capability. Furthermore, the support part 210 can be held by hand, serving as a support point for the palm and distributing hand pressure.

[0054] Please see Figure 1 and Figure 9 In one embodiment of the present invention, the outer shell 101 is provided with a receiving groove 104 for accommodating the grip 200;

[0055] Specifically, when not in use, the grip 200 is placed in the receiving groove 104, and the surface of the device is flat after storage to avoid protruding parts scratching the user or external objects.

[0056] In one embodiment of this utility model, the surface of the grip 200 is covered with an anti-slip layer (not shown in the figure), which can be made of silicone or corrugated rubber to enhance grip friction in humid environments and reduce the risk of the device slipping.

[0057] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
