Description

Technical Field

[0001] This utility model relates to testing equipment, and more particularly to the body and cover of a portable fiber optic testing instrument. Background Technology

[0002] Existing fiber optic testing instruments consist of a main body housing the testing devices and power supply, and a cover that conceals the signal connector protruding from the main body. To use, the cover is opened, the signal connector aligns with the external fiber optic connector, and the testing instrument is activated. However, because the cover is entirely atop the main body with only a partial hinged connection, the main body offers no protection for it. During use, handling the main body and moving it around can easily cause bumps and knocks to the corners of the cover, creating stress on the connection points and potentially leading to loosening and instability over time. When not in use, storing the cover in a toolbox or bag exposes it to pressure from the surrounding environment, causing it to detach. Regardless of use or transport, lateral impacts can easily push the cover open, exposing the signal connector unprotected. When the cover is open, the signal connector protrudes from the main body, making it vulnerable to lateral impacts from external objects, and the connected fiber optic cable is also susceptible to damage. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical problem this invention aims to solve is to provide a portable fiber optic testing instrument that can provide all-time protection for the cover and signal connector.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a portable fiber optic detector, which includes a body, two support arms extending upward from the top left and right sides of the body, a signal connector located on the top surface of the body and between the two support arms, and a flip cover located between the two support arms and capable of covering the signal connector. The flip cover includes a hard plastic shell-shaped cover for covering the signal connector, and an inner support plate extending downward from both sides of the cover. A hinge structure is provided between the inner support plate and the support arms at a rearward position so that the flip cover can be flipped up to the rear. A clearance notch is provided between the cover and the inner support plate to avoid the rear side wall of the body when the flip cover is opened.

[0005] As an improvement to the technical solution of the portable fiber optic detector of this utility model, a positioning structure is provided between the support arm and the inner support plate to match each other. The positioning structure includes a matching spherical protrusion and a corresponding groove.

[0006] As an improvement to the technical solution of the portable fiber optic detector of this utility model, the lower front edge of the inner support plate is an arc shape with the axis of the hinge shaft as the center; the body is provided with a guide groove located below the inner side of the support arm to accommodate the inner support plate.

[0007] As an improvement to the technical solution of the portable fiber optic detector of this utility model, the lower edge of the clearance notch is an anti-rotation part with the maximum opening angle, and the rear side of the guide groove is provided with a limiting part that can abut against the anti-rotation part.

[0008] As an improvement to the technical solution of the portable fiber optic detector of this utility model, the upper edge of the clearance notch is an arc centered on the axis of the hinge shaft.

[0009] As an improvement to the technical solution of the portable fiber optic detector of this utility model, when the flip cover is opened at all angles, the support arm and the inner support plate have a locking structure that is mutually compatible.

[0010] As an improvement to the technical solution of the portable fiber optic detector of this utility model, the support arm has a certain thickness and is higher than the top surface when the flip cover is closed, thereby playing a role in preventing bumps and knocks at the top four corners of the flip cover.

[0011] As an improvement to the technical solution of the portable fiber optic detector of this utility model, the inner side of the support arm is consistent with the left and right side contours of the flip cover.

[0012] The beneficial effects of this utility model are as follows: The portable fiber optic tester has two support arms on the top of its body, with the arms positioned on both sides of the top. The signal connector is located between these arms, and the larger protruding arms on both sides provide excellent protection for the signal connector. Additionally, a flip cover is positioned between the two support arms, allowing the arms to block lateral impacts during handling, transport, or placement in a bag, thus protecting the flip cover. The flip cover, in turn, protects the signal connector. Therefore, the portable fiber optic tester's body and support arms provide all-weather protection for the flip cover and signal connector.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-6As shown, this utility model discloses a portable fiber optic detector, which includes a body 11, two support arms 12 extending upward from the top left and right sides of the body 11, a signal connector 13 located on the top surface of the body 11 and between the two support arms 12, and a flip cover 21 located between the two support arms 12 and capable of covering the signal connector 13. The flip cover 21 includes a hard plastic shell-shaped cover for covering the signal connector 13, and an inner support plate 22 extending downward from both sides of the cover. A hinge structure is provided between the inner support plate 22 and the support arms 12 at a rearward position, so that the flip cover 21 can be flipped up to the rear. A clearance notch 23 is provided between the cover and the inner support plate 22 to avoid the rear side wall of the body when the flip cover 21 is opened. The portable fiber optic detector has two support arms 12 on the top of its body 11, located on either side of the top. The signal connector 13 is positioned between the support arms 12, providing excellent protection for the signal connector 13 due to the greater protrusion of the support arms 12. A flip cover 21 is also positioned between the two support arms 12, protecting it from lateral impacts during handling, transport, or placement in a bag. The flip cover, in turn, protects the signal connector 13. Therefore, the portable fiber optic detector's body 11 and support arms 12 provide continuous protection for the flip cover 21 and the signal connector 13. The hinge structure of the inner support plate 22 is located inside the support arms 12, further protecting the inner support plate 22 embedded within the body 11, and further protecting the hinge structure, thus providing better protection for the flip cover 21. The front and rear edges of the cover fit snugly against the body 11. Because the hinge point is lower than the lower edge of the cover, the cover can be flipped out entirely beyond the lateral projection range of the body, facilitating wiring for testing. Specifically, when the cover is opened to a certain angle, the cover 21 can be fully opened to reveal the signal connector 13, facilitating wiring operations and maintaining a stable wiring state during subsequent testing. The hinge structure includes a hinge hole and a hinge shaft 26, located respectively on the inner side of the lower extension of the support arm 12 and the outer side of the inner support plate 22. Figure 6 As shown. The internal hinge structure allows the flip cover 21 to completely cover the top of the device and its signal connector 13 when closed. The hinge structure is located on the rear side so that the lower front edge of the cover can avoid interference with the signal connector 13 when the flip cover 21 is flipped, making the flipping smooth.

[0021] The support arm 12 and the inner support plate 22 are provided with a positioning structure that adapts to each other. The positioning structure includes a matching spherical protrusion 28 and a corresponding groove. The spherical protrusion 28 is located on the inner support plate 22, and the corresponding groove is located on the inner side of the support arm 12, or on the inner side of the body, at the support part below the support arm 12. The spherical protrusion 28 and the corresponding groove can also be interchanged to achieve the positioning function, so that the flip cover 21 can stop in the closed state when closed.

[0022] The inner support plate 22 has a front lower edge profile that is an arc centered on the axis of the hinge shaft 26. This gives the inner support plate 22 a larger extension dimension, thereby enhancing its connection and support strength. Furthermore, the arc-shaped edge is not obstructed by surrounding structural parts during the flipping process of the cover 21. The body 11 has a guide groove 16 located below the inner side of the support arm 12, which is adapted to accommodate the inner support plate 22. This allows the inner support plate 22 to stay in the guide groove 16 and rotate freely within it, thus enabling the flipping of the cover.

[0023] Furthermore, the lower edge of the clearance notch 23 is an anti-rotation part 29 that opens to its maximum angle, such as... Figure 3 , Figure 6 As shown, the guide groove 16 has a limiting part 18 on its rear side that can abut against the anti-rotation part 29, so that when the flip cover 21 is flipped to be fully open and exposes the signal connector 13, it stops rotating and remains in this flipped-open state.

[0024] Furthermore, the upper edge of the clearance notch 23 is an arc centered on the axis of the hinge shaft, so that the lower edge of the cover can avoid the convex lip 15 on the rear side of the body 11 during the flipping process of the cover 21, thus avoiding interference and hindering the rotation of the cover 21.

[0025] When the flip cover 21 is fully opened, the support arm 12 and the inner support plate 22 have a locking structure that is mutually compatible. This locking structure can use a part of the previous positioning structure, namely the spherical protrusion of the flip cover, and set a corresponding adapter structure on the inner side of the support arm 12 or its downward extension, so that when the flip cover 21 is opened to a certain angle, it can stop in the open state at the corresponding angle, so that the flip cover 21 does not obstruct the operation of connecting / disconnecting optical fibers to the signal structure.

[0026] The support arm 12 has a certain thickness and is higher than the top surface of the flip cover 21 when it is closed, so as to protect the four top corners and four sides of the flip cover 21 from bumps and knocks, prevent accidental external forces from bumping the flip cover 21 from the side, and prevent accidental pushing force from opening the flip cover 21, thus protecting both the flip cover 21 and the signal connector.

[0027] Furthermore, the inner side of the support arm 12 is consistent with the left and right side contours of the flip cover 21 to prevent external objects from touching or scratching the flip cover 21 and opening it. The inner side of the support arm 12 can also be larger than the contour of the flip cover 21 to provide protection, but a large difference in contour will affect the aesthetics.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
