Description

Technical Field

[0001] This utility model relates to the field of optoelectronic communication technology, and in particular to a portable multi-interface insertion loss tester device. Background Technology

[0002] The portable multi-interface insertion and return loss tester is a professional portable device used in the field of optical communication for the accurate measurement of key performance parameters of passive optical devices. Its core function is to detect insertion loss and return loss. At the same time, the "multi-interface" design adapts to diverse testing needs and takes into account portability to meet the needs of field testing scenarios.

[0003] Existing testing devices integrate folding handles, made of plastic or metal, on the top or side of the device. These handles can be unfolded without additional tools, making them convenient for short-distance hand carrying. When folded, they do not take up extra space. However, while this is acceptable for short-distance hand carrying, the small contact area between the handle and the palm, coupled with the concentrated weight, can lead to hand fatigue and make carrying and transferring difficult over extended periods. Existing technology includes a pre-installed shoulder strap interface, such as a metal buckle, which can be used with a detachable shoulder strap. For short distances, the handle can be used, while for long distances or extended transfers, the shoulder strap can be switched to distribute the weight to the shoulders and back, reducing hand strain. However, since the back widths of different people vary, the fixed position of existing shoulder straps cannot be adjusted to suit different users' backs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable multi-interface insertion and return damage tester, which aims to improve the problem that the position of the existing shoulder strap is fixed and cannot be used according to the back of different users in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable multi-interface insertion loss tester device, comprising a body, wherein multiple adjustment mechanisms are equidistantly fixedly connected to the rear side of the outer wall of the body, the adjustment mechanisms being used to adjust the length; multiple lifting mechanisms are equidistantly fixedly connected to the left and right sides of the outer wall of the body, the lifting mechanisms being used to adjust the height to support the body; each adjustment mechanism includes multiple hollow blocks, the multiple hollow blocks being equidistantly fixedly connected to the rear side of the outer wall of the body; each hollow block has a threaded rod rotatably connected to its inner wall; the outer wall of the upper threaded rod is threadedly connected to a hollow block; the outer wall of the lower threaded rod is threadedly connected to a grooved block; each hollow block has a rotating column rotatably connected to its inner wall; an adjustment strap is fixedly connected to the outer wall of the rotating column; an insertion block is fixedly connected to the bottom end of the adjustment strap; and a locking assembly is fixedly connected to the left side of the outer wall of each hollow block.

[0006] As a further description of the above technical solution:

[0007] The engaging assembly includes a support plate, which is fixedly connected to the left side of the outer wall of the hollow block. A pull rod is slidably connected to the top of the inner wall of the support plate, and a spring is fixedly connected to the bottom of the support plate. Multiple slots are equidistantly opened around the outer wall of the rotating column.

[0008] As a further description of the above technical solution:

[0009] The lifting mechanism includes multiple elongated plates, which are equidistantly fixedly connected to the left and right sides of the outer wall of the machine body. A rotating short column is rotatably connected to the middle of the inner wall of each elongated plate, and a gear is fixedly connected to the outer wall of the rotating short column. A rack is slidably connected inside each elongated plate, and a fixing component is fixedly connected to the upper middle part of the outer wall of each elongated plate on opposite sides.

[0010] As a further description of the above technical solution:

[0011] The fixing assembly includes multiple support plates, which are respectively fixedly connected to the upper part of the outer wall of the elongated plate on opposite sides. A threaded short column is threadedly connected to the middle of the inner wall of each support plate, and a semi-circular locking block is fixedly connected to the bottom end of the threaded short column. Multiple elongated grooves are equidistantly formed around the outer wall of the rotating short column, and foot pads are fixedly connected to the bottom of each rack.

[0012] As a further description of the above technical solution:

[0013] The gear meshes with the rack, and the semi-circular locking block engages with the elongated groove.

[0014] As a further description of the above technical solution:

[0015] The pull rod engages with the slot, and the insert block engages with the recessed block.

[0016] As a further description of the above technical solution:

[0017] A handle is fixedly connected to the top of the body, and a protective sleeve is fixedly connected to the outer wall of the handle.

[0018] As a further description of the above technical solution:

[0019] The top front side of the machine body is threaded with a bolt, the outer wall of the bolt is threaded with a label, and multiple docking detection grooves are fixedly connected at equal intervals on the outer front side of the machine body.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, in the adjustment mechanism, a hollow long block supports a threaded rod. Rotating the threaded rod allows the hollow block and the grooved block to move axially, changing the spacing to adjust the length of the shoulder strap to accommodate different shoulder widths. The adjustable shoulder strap is connected to the hollow block via a rotating column, allowing for angle adjustment by rotation. Once the desired angle is achieved, the spring push-pull rod is engaged in the slot for fixation. Pulling the pull rod unlocks the strap. The insertion block engages with the grooved block to enable the shoulder strap to be installed and removed, solving the problem of traditional shoulder strap fixation and balancing portability and stability.

[0022] 2. In this utility model, when adjusting the height of the machine body, first rotate the threaded short column to disengage the semi-circular locking block from the elongated groove of the rotating short column to unlock it. Rotating the short column causes the gear and rack to mesh, driving the rack to slide up and down along the elongated plate. Rotating the gear in the forward direction causes the rack to extend downward, raising the machine body; rotating in the reverse direction causes the rack to retract, lowering the machine body. After adjusting to the desired height, rotate the threaded short column in the reverse direction to allow the semi-circular locking block to re-engage in the elongated groove, locking the height. Multiple lifting mechanisms can simultaneously level the machine body, or adjust one side to adapt to uneven ground, meeting different operating height requirements. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a portable multi-interface insertion loss tester device, comprising a body 1. Multiple adjustment mechanisms 2 are equidistantly fixed to the rear side of the outer wall of the body 1, used to adjust the length. Multiple lifting mechanisms 3 are equidistantly fixed to the left and right sides of the outer wall of the body 1, used to adjust the height and support the body 1. Each adjustment mechanism 2 includes multiple hollow elongated blocks 201, equidistantly fixed to the rear side of the outer wall of the body 1. Threaded rods 202 are rotatably connected to the inner walls of each hollow elongated block 201. Hollow blocks 203 are threadedly connected to the outer walls of the upper threaded rods 202, and grooved blocks 207 are threadedly connected to the outer walls of the lower threaded rods 202. The inner wall of block 203 is rotatably connected to rotating columns 204. The outer wall of rotating columns 204 is fixedly connected to adjusting straps 205. The bottom end of adjusting straps 205 is fixedly connected to insert blocks 206. The left side of the outer wall of hollow block 203 is fixedly connected to engaging components 208. Engaging components 208 include support plates 2081. Support plates 2081 are fixedly connected to the left side of the outer wall of hollow block 203. The top of the inner wall of support plates 2081 is slidably connected to pull rods 2082. The bottom of support plates 2081 is fixedly connected to springs 2083. Multiple slots 2084 are equidistantly opened around the outer wall of rotating columns 204. Pull rods 2082 engage with slots 2084. Insert blocks 206 engage with recessed blocks 207.

[0033] Specifically, in the adjustment mechanism 2, the hollow block 201 provides fixed support for the threaded rod 202. When it is necessary to adjust the overall length of the adjustable shoulder strap 205, the upper or lower threaded rod 202 is rotated, and the hollow block 203 or groove block 207 on its outer wall will move along the axial direction of the threaded rod 202, thereby changing the distance between the hollow block 203 and the groove block 207, so as to achieve the length adaptation of the adjustable shoulder strap 205. For example, users with wider shoulders can increase the distance between the two by rotating the threaded rod 202, so that the adjustable shoulder strap 205 unfolds more smoothly; users with narrower shoulders can reduce the distance to prevent the shoulder strap from slipping. The adjustable shoulder strap 205 is connected to the hollow block 203 through the rotating column 204, and can rotate around the rotating column 204 to adjust the tilt angle. Once the angle is determined, the spring 2083 in the engaging assembly 208 pushes the pull rod 2082 downwards, engaging it with the slot 2084 on the outer wall of the rotating column 204, thus fixing the position of the rotating column 204 and ensuring that the shoulder strap angle adapts to the user's shoulder curve. If the angle needs to be readjusted, pull the pull rod 2082 upwards to compress the spring 2083, disengaging it from the slot 2084 to release the rotating column 204. The insert 206 at the bottom of the adjustable shoulder strap 205 can be inserted into the groove 207 on the lower side, achieving quick connection between the shoulder strap and the body 1. When disassembling, simply pull out the insert 206, which is convenient for separate storage or replacement of the shoulder strap. This solves the problem of traditional shoulder straps having a fixed position and being unable to adapt to different back widths, while also taking into account portability and operational stability, meeting the carrying and testing needs in multiple scenarios.

[0034] Reference Figure 2 , Figure 3 and Figure 6 The lifting mechanism 3 includes multiple elongated plates 301, which are equidistantly fixed to the left and right sides of the outer wall of the body 1. A rotating short column 304 is rotatably connected to the center of the inner wall of each elongated plate 301. A gear 303 is fixedly connected to the outer wall of the rotating short column 304. A rack 302 is slidably connected inside each elongated plate 301. Fixing components 305 are fixedly connected to the upper middle part of the outer wall of each elongated plate 301 on opposite sides. Each fixing component 305 includes multiple support plates 3051. 1. The upper part of the outer wall of the elongated plate 301 is fixedly connected to the opposite side. The inner wall of the support plate 3051 is threadedly connected to the middle of the threaded short column 3053. The bottom end of the threaded short column 3053 is fixedly connected to the semi-circular locking block 3052. The outer wall of the rotating short column 304 is provided with multiple elongated grooves 3054 at equal intervals. The bottom of the rack 302 is fixedly connected to the foot pad 3055. The gear 303 meshes with the rack 302. The semi-circular locking block 3052 engages with the elongated groove 3054.

[0035] Specifically, when adjusting the height of the machine body 1, first release the restriction of the fixing component 305, rotate the threaded short column 3053, causing it to drive the semi-circular locking block 3052 upward, disengaging it from the elongated groove 3054 on the outer wall of the rotating short column 304, releasing the rotational freedom of the rotating short column 304. Subsequently, rotating the short column 304 causes the gear 303 fixed on its outer wall to rotate synchronously. Since the gear 303 meshes with the rack 302, the rack 302 slides up and down along the inner wall of the elongated plate 301. When the gear 303 rotates in the forward direction, the rack 302 extends downward, increasing the distance between the machine body 1 and the ground through the bottom foot pad 3055; when the gear 303 rotates in the reverse direction, the rack 302 retracts upward, lowering the machine body 1. When the height of body 1 is adjusted to the required height, the threaded short column 3053 is rotated in the reverse direction. Under the action of threaded transmission, the semi-circular locking block 3052 moves downward and re-locks into the elongated groove 3054 corresponding to the rotating short column 304, restricting the rotation of the rotating short column 304. Thus, the gear 303 and the rack 302 are meshed and locked, fixing the extension length of the rack 302 and ensuring that the foot pad 3055 stably supports body 1. Multiple lifting mechanisms 3 are distributed on the left and right sides of body 1. They can be adjusted synchronously to ensure that body 1 is placed horizontally and avoid tilting; or the height of one side can be adjusted individually to adapt to uneven ground such as construction sites and outdoor grass, while meeting the operating height needs of different users.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A handle 4 is fixedly connected to the top of the body 1, a protective sleeve 5 is fixedly connected to the outer wall of the handle 4, a bolt 6 is threadedly connected to the front top of the body 1, a label 7 is threadedly connected to the outer wall of the bolt 6, and multiple docking detection grooves 8 are fixedly connected at equal intervals to the front outer wall of the body 1.

[0037] Specifically, the handle 4 on the top of the body 1 allows the user to carry it over short distances. The protective sleeve 5 on its outer wall increases the friction between the hand and the handle 4, improving grip comfort and reducing hand fatigue when carrying it. The front top of the body 1 is connected to the label 7 by bolts 6. The bolts 6 serve to fix the label 7, which can be used to mark instrument information for easy identification. Multiple docking detection slots 8, which are fixed at equal intervals on the front outer wall of the body 1, are the key interfaces for insertion loss and return loss testing. During testing, the connection end of the external optical device is inserted into the docking detection slot 8 to realize the transmission and detection of optical signals, and to complete the measurement of parameters such as insertion loss and return loss.

[0038] Working principle: In adjustment mechanism 2, the hollow block 201 provides fixed support for the threaded rod 202. When it is necessary to adjust the overall length of the shoulder strap 205, rotating the upper or lower threaded rod 202 will cause the hollow block 203 or the grooved block 207 on its outer wall to move along the axial direction of the threaded rod 202, thereby changing the distance between the hollow block 203 and the grooved block 207, thus achieving the adjustment of the shoulder strap 205 to a suitable length. For example, users with wider shoulders can increase the distance between them by rotating the threaded rod 202. The spacing is adjusted to make the adjustable shoulder strap 205 unfold more smoothly; for those with narrower shoulder widths, the spacing is reduced to prevent the shoulder strap from slipping. The adjustable shoulder strap 205 is connected to the hollow block 203 through the rotating column 204, and can rotate around the rotating column 204 to adjust the tilt angle. When the angle is determined, the spring 2083 in the engaging assembly 208 will push the pull rod 2082 to slide downward, so that it engages with the slot 2084 on the outer wall of the rotating column 204, thereby fixing the position of the rotating column 204 and ensuring that the shoulder strap angle is adapted to the user's shoulder curve. If the angle needs to be readjusted, pull the lever 2082 upward to compress the spring 2083, so that it disengages from the slot 2084 and releases the rotating column 204. Adjust the insertion block 206 at the bottom of the shoulder strap 205 to insert into the groove block 207 on the lower side, so as to achieve quick connection between the shoulder strap and the body 1. When disassembling, simply pull out the insertion block 206. It is convenient to store or replace the shoulder strap separately. This solves the problem of the fixed position of the traditional shoulder strap and its inability to adapt to different back widths. It also takes into account portability and operational stability, and meets the carrying and testing needs in multiple scenarios.

[0039] When the height of the machine body 1 needs to be adjusted, first release the restriction of the fixing component 305, rotate the threaded short column 3053, causing it to drive the semi-circular locking block 3052 to move upward, disengaging it from the elongated groove 3054 on the outer wall of the rotating short column 304, releasing the rotational freedom of the rotating short column 304. Subsequently, rotate the short column 304, and the gear 303 fixed on its outer wall rotates synchronously. Since the gear 303 meshes with the rack 302, the rack 302 will slide up and down along the inner wall of the elongated plate 301. When the gear 303 rotates in the forward direction, the rack 302 extends downward, increasing the distance between the machine body 1 and the ground through the bottom foot pad 3055; when the gear 303 rotates in the reverse direction, the rack 302 retracts upward, lowering the machine body 1. When the machine body 1 is adjusted to the required height, the threaded short column 3053 is rotated in the reverse direction. Under the action of threaded transmission, the semi-circular locking block 3052 moves downward and re-locks into the elongated groove 3054 corresponding to the rotating short column 304, restricting the rotation of the rotating short column 304. Thus, the gear 303 and the rack 302 are meshed and locked, fixing the extension length of the rack 302 and ensuring that the foot pad 3055 stably supports the machine body 1. Multiple lifting mechanisms 3 are distributed on the left and right sides of the machine body 1. They can be adjusted synchronously to ensure that the machine body 1 is placed horizontally and avoid tilting; or the height of one side can be adjusted individually to adapt to uneven ground such as construction sites and outdoor grass, while meeting the operating height needs of different users.
