Description

Technical Field

[0001] This utility model relates to the field of fiber optic splitter boxes, and more particularly to a quick-connect base station fiber optic splitter box. Background Technology

[0002] Mining fiber optic junction boxes are fiber optic signal distribution and protection devices specifically designed for mining environments, especially underground ones. Classified as explosion-proof mining communication equipment, they utilize high-strength, flame-retardant, and anti-static materials, with a protection rating greater than or equal to IP65. Some models have obtained explosion-proof certification, enabling stable operation in dusty, humid, and vibrating underground environments. Their core function is to branch, splice, and connect mining communication fiber optic cables, separating multi-core fibers from the main fiber optic cable into single-core fibers to connect mining switches, sensors, and personnel positioning equipment. Simultaneously, through a sealed structure and splice tray design, they ensure the stability of fiber optic connections and the quality of optical signal transmission, making them a crucial node for signal splitting and protection in mining fiber optic communication systems.

[0003] Existing mining fiber optic splitter boxes mainly consist of a splitter box, splitter modules, sealing connectors, covers, and fixing screws. When it is necessary to split the optical cable into multiple fibers, the first step is to remove the multiple fixing screws connecting the cover to the splitter box. Then, the optical cable is inserted into the splitter module using the sealing connector. Multiple fibers from the splitter module on the other side are then pulled out using the sealing connector on the other side. Finally, the cover is fixed to the splitter box using multiple fixing screws. Because the existing cover and splitter box are fixed together with multiple screws, maintenance and repair require disassembly using tools, causing inconvenience and low efficiency for maintenance personnel. Furthermore, most existing mining fiber optic splitter boxes are directly fixed to the surface of the mine wall. Due to the high humidity in mines, although the surface of the existing mining fiber optic splitter boxes is made of corrosion-resistant and rust-resistant materials, prolonged placement can cause moisture to seep into the splitter box, preventing optical signal transmission and causing the main trunk and branch lines to malfunction.

[0004] Therefore, those skilled in the art have provided a quick-connect base station fiber optic splitter box to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-plug base station fiber optic splitter box. When installation is required, multiple fixing bolts are used to secure it to a suitable underground wall through multiple bolt holes in the base. After fixing, the first spring clip in the first slot is pressed to adjust its position relative to the wall. After adjustment, the L-shaped protrusion and the first slider are slidably positioned in the second and first sliding grooves respectively. Finally, it is secured by the second spring clip in the second slot. This design solves the problem of traditionally installing the fiber optic splitter box directly on the wall during installation. The cover is directly in contact with the wall surface. Due to the excessive humidity in the mine, moisture adheres to the wall surface, causing it to seep into the interior and preventing the main and branch lines from working. During maintenance, pressing the spring clip allows the No. 1 fixing plate to pass through the hole in the No. 1 fixing block, thus pulling out the cover. This solves the problem of traditional maintenance and repair methods that require removing multiple fixing screws to fix the cover to the box body with tools, and then using multiple fixing screws to fix the cover to the box body after maintenance. This necessitates maintenance personnel to repeatedly disassemble and reassemble the cover, causing inconvenience and low work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-plug base station fiber optic splitter box, including a fiber optic splice box, the fiber optic splice box including a box shell, a fixing bracket installed on one side of the box shell to avoid direct contact with the wall, the fixing bracket including a fixing seat, a fixing sleeve rod fixedly provided on one side surface of the fixing seat near the front and rear ends, a support rod fixedly provided at the other end of the four fixing sleeve rods, a support block fixedly provided on both ends surface of the support rod near the ends, a first slider fixedly provided at the end of one end surface of the two support blocks, a second sliding groove fixedly opened on both ends of the outer wall of the support block near the first slider, a cover embedded in one side surface of the box shell, and a locking component fixedly provided on both ends surface of the outer wall of the cover near the front and rear ends; The locking assembly includes a second fixing block, which is fixedly installed at one end of the outer wall of the cover and near the end of that end. A first fixing plate is fixedly installed at the center of one side surface of the second fixing block. A third spring buckle is fixedly installed at both ends of the outer wall of the first fixing plate and near the end of one side surface.

[0007] Furthermore, a sealing joint to prevent dust from entering the interior is fixedly installed at the center of the front and rear ends of the outer wall of the box shell. A fixing block is fixedly installed at the front and rear ends of the outer wall of the box shell and near the end of one side. A junction box is fixedly installed at the center of one side of the inner surface of the box shell. A branch plate to prevent wiring from tangling is fixedly installed on one side of the inner wall of the box shell and near the two ends of the junction box.

[0008] Furthermore, a fixing hole is provided inside the first fixing block, and the first fixing plate is inserted into the fixing hole provided inside the first fixing block.

[0009] Furthermore, an L-shaped protrusion is fixedly provided on one side surface of the outer wall of the box body and at both ends. A first sliding groove is fixedly opened on the inner surface of the L-shaped protrusion, and the first slider is slidably disposed in the first sliding groove.

[0010] Furthermore, a second spring buckle is fixedly provided at both ends of the first slider and near the upper end, and a second slot is fixedly provided at both ends of the L-shaped protrusion and near the upper end, and the second spring buckle is engaged in the second slot.

[0011] Furthermore, the fixed sleeve is divided into a first sleeve and a second sleeve. The outer wall of the first sleeve is fixedly provided with a plurality of No. 1 slots on one end surface, and the outer wall of the second sleeve is fixedly provided with a plurality of No. 1 spring buckles. The plurality of No. 1 spring buckles are engaged in the No. 1 slots.

[0012] Furthermore, bolt holes are provided on one side surface of the fixing base near the four corners, and fixing bolts are inserted through the bolt holes.

[0013] This utility model has the following beneficial effects: When the installer needs to perform installation work, the base is fixed to the wall using the bolt holes at the four corners using fixing bolts. The first sleeve slides onto the first sleeve rod by pressing the first spring clips in the multiple first slots, allowing adjustment of the distance from the wall according to work requirements. The fiber optic splice box is slidably positioned in the first and second sliding grooves using the L-shaped protrusion on one side and the first slider on the support block. Finally, the second spring clips at both ends of the first slider, near the top end, engage with the second slots on both ends of the L-shaped protrusion, securing the splice. This solution overcomes the traditional method of direct contact with the wall during installation. Although the wall-mounted material is rust- and corrosion-resistant, it cannot be fixed for a long time, leading to moisture seeping into the wall surface and causing the main and branch lines to malfunction. When maintenance personnel perform maintenance, they press the No. 3 spring clip to pull the No. 1 fixing plate out of the No. 1 fixing block hole. At the same time, the plate is pulled out, and the cover embedded in the fiber optic splice box is also pulled out. This solves the problem that maintenance personnel need to remove multiple fixing screws one by one to separate the cover from the box, which is inconvenient and leads to poor work efficiency.

[0016] 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.

[0017] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides an embodiment of a quick-plug base station fiber optic splitter box, including a fiber optic splice box 1. The fiber optic splice box 1 includes a box shell 101. A fixing bracket 2 is installed on one side of the box shell 101 to avoid direct contact with the wall. The fixing bracket 2 includes a fixing seat 201. Fixing sleeve rods 202 are fixedly installed on one side surface of the fixing seat 201 near the front and rear ends. The fixing seat 201 is made of 316 stainless steel, which is corrosion-resistant, rust-proof, and moisture-resistant, and has an internal grounding wire, suitable for long-term fixing. Support rods 204 are fixedly installed at the other ends of the four fixing sleeve rods 202. The four fixing sleeve rods 202 are made of 316 stainless steel, which is corrosion-resistant, rust-proof, and can bear the weight of the fiber optic splice box 1 for a long time. The splice part is finely polished and the splice contact surface is equipped with rubber cushioning material to reduce the risk of sparks caused by vibration or movement. Support blocks 205 are fixedly installed on both ends surface of the support rods 204 near the rear ends. The support rods 204 are made of stainless steel to prevent them from falling off due to corrosion. A first slider 206 is fixedly installed at the end of one end surface of block 205. A second groove 208 is fixedly opened at both ends of the outer wall of block 205 near the first slider 206. The fixing sleeve 202 is divided into a first sleeve and a second sleeve. Multiple first-order slots are fixedly opened on one end surface of the outer wall of the first sleeve, and multiple first-order spring clips 203 are fixedly installed on one end surface of the outer wall of the second sleeve. The multiple first-order spring clips 203 are engaged in the first-order slots. The contact surfaces of the first sleeve and the second sleeve are cushioned by rubber material and the sliding surfaces... The surface is finely polished to avoid the risk of sparks caused by burrs. Bolt holes 7 are opened on one side of the fixed base 201 near the four corners and a fixing bolt is inserted through the bolt holes 7. A cover 3 is embedded on one side of the outer shell 101. A rubber sealing ring is provided on the embedded part of the cover 3 to prevent dust and moisture from entering the inner part of the outer shell 101 due to incomplete sealing, which could damage the optical cable and optical fiber. Locking components 4 are fixedly installed on both ends of the outer wall of the cover 3 near the front and rear ends. The locking assembly 4 includes a second fixing block 401, which is fixedly installed at one end of the outer wall of the cover 3 and near the end of that end. The second fixing block 401 is made of 316 stainless steel to avoid damage caused by corrosion. A first fixing plate 402 is fixedly installed at the center of one side surface of the second fixing block 401. The sliding surface of the first fixing plate 402 is finely polished to avoid burrs that could cause sparks. A third spring buckle 403 is fixedly installed at both ends of the outer wall of the first fixing plate 402 and near the end of one side surface.

[0018] Specifically, when installation is required, multiple fixing bolts are used to fix the fixing seat 201 to the wall surface through multiple bolt holes 7. The first sleeve and the second sleeve are moved by pressing the first spring buckle 203 in the first slot. After the movement is completed, the first spring buckle 203 is used to lock them into the first slot for fixation. After fixation, the L-shaped protrusion 6 on one side of the fiber optic splice box 1 and the first slider 206 are used to make them slide into the second slide groove 208 and the first slide groove 5 respectively. The second spring buckle 207 on the front and rear ends of the first slider 206 near the upper end is used to lock it into the second slot on the front and rear ends of the L-shaped protrusion 6 near the upper end, thus fixing the fiber optic splice box 1. This solves the problem that in the traditional installation process, multiple fixing screws are used to make the splice box 1 directly contact the wall. Due to the high humidity in the mine, water vapor adheres to the wall surface. Prolonged contact with the wall causes moisture to enter, resulting in the main line and branch line not working. When maintenance personnel perform maintenance work, they press the No. 3 spring clip 403 to pull out the No. 1 fixing plate 402 from the hole in the No. 1 fixing block 102. At the same time, the cover 3 is separated from the fiber optic splice box 1. After maintenance is completed, the No. 3 spring clip 403 is pressed to insert the No. 1 fixing plate 402 into the hole in the No. 1 fixing block 102. The No. 3 spring clip 403 is then released to close the cover 3 and the fiber optic splice box 1. Because the part of the cover 3 embedded inside is equipped with a rubber ring, it can prevent dust and moisture from entering due to poor sealing. This solves the problem that traditional maintenance work requires the use of tools to remove the fixing screws of the box cover and the box body, and installation is required after maintenance, which brings inconvenience to maintenance personnel and leads to poor work efficiency.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A sealing connector 103 is fixedly installed at the center of the front and rear ends of the outer wall of the housing 101 to prevent dust from entering the interior. The sealing connector 103 is made of 316 stainless steel to prevent dust from entering, which fully meets the explosion-proof requirements for underground mining. A first fixing block 102 is fixedly installed at the front and rear ends of the outer wall of the housing 101, near the end of one side. A junction box 105 is fixedly installed at the center of one side of the inner surface of the housing 101. A splitter plate 104 is fixedly installed on one side of the inner wall of the housing 101, near the two ends of the junction box 105, to prevent wiring from getting tangled. The splitter plate 104 can separate the optical fiber and the optical cable one by one, avoiding the need to find the damaged part one by one during maintenance and inspection. A fixing hole is opened inside the first fixing block 102. A first fixing plate 402 is inserted into the fixing hole opened inside the first fixing block 102. The fixing hole inside the first fixing block 102 has been finely polished to remove burrs, so as to prevent the first fixing plate from getting tangled. To mitigate the risk of sparks due to friction during the extraction of 402, an L-shaped protrusion 6 is fixedly installed on one side of the outer wall of the outer casing 101 and at both ends. The L-shaped protrusion 6 is made of 316 stainless steel and its sliding surface is coated with a mining-grade compliant lubricant to reduce friction and prevent sparks. A first groove 5 is fixedly opened on the inner surface of the L-shaped protrusion 6, and a first slider 206 is slidably positioned within the first groove 5. The sliding surface of the first slider 206 is coated with a mining-grade compliant lubricant to prevent friction during sliding. A second spring clip 207 is fixedly installed at both ends of the first slider 206 and near the upper end. A second slot is fixedly opened at both ends of the L-shaped protrusion 6 and near the upper end. The second spring clip 207 is engaged in the second slot to secure it. The second spring clip 207 is made of a mining-grade explosion-proof, corrosion-resistant, and rust-resistant material to prevent corrosion that could prevent it from being pressed down.

[0020] Specifically, after installation, the external backbone mining optical cable is inserted into the housing 101 through the sealing connector 103 on one side. The sealing connector 103 is sealed by a sealing gasket and a locking nut to prevent dust and moisture from entering and causing malfunction. Inside the housing 101, the outer sheath of the backbone mining optical cable is stripped using tools, allowing the internal optical fiber to be connected to the plug of the junction box 105. Connecting it to the branch single-core optical fiber ensures low-loss optical signal transmission. After connection, it is connected to multiple devices and terminals through the sealing connector 103 on the other side, thus distributing the backbone signal to multiple terminals and devices. The cover 3 is then closed. When separating and closing the box shell 101, the No. 3 spring clips 403 at both ends are pressed by the No. 1 fixing plate 402 to pass through the hole opened on one end surface of the No. 1 fixing block 102. The No. 3 spring clips 403 are released to fix it to the surface of the No. 1 fixing block 102 to prevent it from moving and causing moisture and dust to enter. After the fixing seat 201 and the fixing sleeve rod 202 are fixed and adjusted, the L-shaped protrusion 6 on one side surface of the box shell 101 is used to make it slide in the second slide groove 208. After the sliding is fixed, the No. 2 spring clip 207 on one side of the first slider 206 is used to make it engage in the No. 2 slot to fix it, so as to avoid the problem of movement and damage due to improper fixing.

[0021] Working principle: When the installer performs the installation, multiple fixing bolts are used to fix the fixing base 201 to the required installation position through the bolt holes 7. The first sleeve and the second sleeve are moved by pressing the first spring buckle 203 in the first slot. When it is moved to a suitable position and does not affect other work, the first slider 206 at one end of the support block 205 is slidably set in the first slide groove 5. At the same time as sliding, the L-shaped protrusion 6 is slidably set in the second slide groove 208. After sliding, the second spring buckle 207 at one end of the first slider 206 and near the front and rear ends of the upper end is used to lock it in the second slot to prevent it from moving. This solves the problem that when the wall is fixed by multiple fixing screws during the installation work, although the surface of the wall is made of corrosion-resistant and rust-resistant material, after a long time, moisture will enter the inside of the box shell 101 through the surface of the wall, causing moisture to seep into the main line and branch line, resulting in damage and failure to work. When maintenance or repair is required, pressing the third spring clip 403 causes the first fixing plate 402 to be pulled out through the fixing hole of the first fixing block 102. Simultaneously, the cover 3 separates from the outer shell 101. The branch plate 104 allows for quick location of the line requiring maintenance or repair. After maintenance, pressing the third spring clip 403 causes the first fixing plate 402 to pass through the fixing hole. Simultaneously, the third spring clip 403 is released to secure it. Because the embedded part of the cover 3 is sealed with a rubber ring, dust and moisture can be reduced from entering and damaging the main or branch lines. This solves the problem of inconvenience and slow work efficiency caused by the traditional method of maintenance where the cover and box are fixed together with multiple screws, requiring disassembly and reassembly of each part.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
