Description

Technical Field

[0001] The invention relates to the technical field of optical cable joint boxes, and in particular to a compression-resistant and reinforced optical cable joint box. Background Art

[0002] The cable splice box provides external physical protection for the optical cable and optical fiber joints, preventing external objects from squeezing and damaging the optical cable inside the splice box under the action of gravity. Secondly, it can prevent damage to the optical cable and optical fiber joints such as moisture, dust, and chemical corrosion. This protection ensures the long-term stability and reliability of the optical cable and optical fiber joints. After searching the existing published technical documents, the patent with Chinese patent announcement number CN102540369A discloses an optical cable joint box, which is mainly provided with a lower sealing baffle on the front side of the lower cavity, the lower sealing baffle is inserted upward into the upper cavity, the front surface of the lower sealing baffle inserted into the upper cavity is sealed with the inner surface of the upper cavity, and an upper sealing ridge is provided on the lower end surface of the upper side plate at the front side of the front sealing strip, and the upper sealing ridge is embedded downward and inserted into the lower sealing groove on the upper end surface of the lower side plate. The optical cable joint box of this technology has the characteristics of excellent sealing performance, long service life, and can ensure the communication quality of the optical cable line. However, the optical cable joint box still has the following problems during use.

[0003] When the optical cable junction box is used to protect the wiring of the optical cable, although the entire outer shell of the optical cable junction box can provide pressure resistance of heavy objects, the heavy objects continue to squeeze the optical cable junction box, which will cause continuous squeezing and damage of the optical cable junction box. This requires maintenance personnel to regularly inspect the optical cable junction box to check whether there are heavy objects continuously squeezing the optical cable junction box, so as to clean the heavy objects and avoid damage to the optical cable junction box. However, the inspection interval is long, so it is difficult to automatically know the squeezing of heavy objects in time, and it is also difficult to automatically detach the squeezing top heavy objects and the side heavy objects. This results in a long squeezing time of heavy objects, and the optical cable junction box is extremely easy to deform and damage, resulting in poor compressive durability of the optical cable junction box. For this reason, a compression-reinforced optical cable junction box is provided. Summary of the invention

Bolts are provided inside the upper cover and near its four corner lines, and the outer wall of the bolt is threadedly connected to the inner wall of the lower cover. Threaded sleeves are fixedly connected to both sides of the lower cover and located above the support frame, and a rubber sleeve is bonded to the inner wall of the threaded sleeve; the outer wall of the threaded sleeve is threadedly connected to an extrusion nut. A slider is fixedly connected to the bottom end of the outer wall of the guide column, and a slide groove is opened under the slider; the two sliders are slidably connected to the slide groove, and the outer wall of the slider is a smooth surface; a pressure strip is fixedly connected to the bottom end of the arc-shaped groove plate, and a top pressure sensor is fixedly installed between the pressure strip and the upper cover; a joint mounting row is fixedly connected to the bottom end of the inner wall of the lower cover, and a plurality of screws are threadedly connected to the top of the joint mounting row, and a battery is provided on one side of the joint mounting row, and a wireless controller is installed on the upper surface of the battery; the wireless controller and the lower cover are fixedly connected to the battery.

[0007] When the present technical solution is in use, when the weight is pressed against the upper surface of the arc groove plate, when the pressure value sensed by the top pressure sensor exceeds the disengagement pressure value set by the wireless controller, the reduction motor drives the linkage screw to rotate, and the linkage screw drives the sleeve block to move right under the action of the thread transmission force, while the other moves to the left, the linkage block drives the guide frame to move right, the slide column drives the two limit rings to slide vertically, and the guide column drives the slider to slide right along the inside of the slide groove.

The two push plates can push the weight pressed against the upper surface of the arc groove plate to move until the weight no longer contacts the upper surface of the arc groove plate.

[0008] Preferably, the side timely disengagement mechanism includes a bidirectional screw rotatably mounted inside the support frame, and the lower cover is fixedly connected to the support frame; a transmission motor is fixedly mounted on one side of the support frame, and the transmission motor is used to drive the bidirectional screw to rotate, and the outer wall of the bidirectional screw is threadedly connected to two sleeve groove blocks, and one side of each sleeve groove block is slidably connected to a pressure column, and a rubber block is fixedly connected between the pressure column and the sleeve groove block; one end of the pressure column is fixedly connected to a connecting block, a support block is welded on one side of the connecting block, and a sliding rod is fixedly connected to one side of the support block, and the outer wall of the sliding rod is provided with a sleeve block fixedly connected to the sleeve groove block, and the inner wall of the sleeve block is slidably connected to the sliding rod; the other side of each of the connecting blocks is fixedly connected to a push plate, a gap is provided between the push plate and the lower cover, and push strips are fixedly connected on both sides of the push plate; a double-sided sensor assembly is provided between the two push strips. The two sleeve groove blocks are slidably connected to the support frame, and the two threads on the outer wall of the bidirectional screw are opposite and symmetrical.

[0009] When the present technical solution is in use, the transmission motor drives the bidirectional screw to rotate forward inside the support frame, the distance between the two sleeve groove blocks increases, the rubber block drives the pressure column to move right, the connection block drives the support block to move right, and the support block drives the slide bar to move right, while the sleeve groove block causes the sleeve block to move right. The push plate will simultaneously drive the two push bars to move right, while the other push plate will move left. This allows the heavy objects on the side of the push plate to be at a large distance from the side of the lower cover. Then the transmission motor is started to drive the bidirectional screw to reverse, and the bidirectional screw drives the two sleeve groove blocks to move closer to each other under the action of the thread transmission force, the pressure column drives the connection block to move left, the connection block drives the push plate to move left, and the other push plate moves right, so that the push plate and the heavy objects on the side can be completely separated from the operation.

[0010] Preferably, the double-sided sensing assembly includes two sensing shafts arranged between the two push strips; one end of each sensing shaft is fixedly connected to a sliding sleeve block, and the inner wall of the sliding sleeve block is slidably connected to a support rod, one end of the support rod is fixedly installed with a sliding frame, the sliding frame is fixedly connected to the lower cover, and the outer walls of the two sliding sleeve blocks are slidably connected to the sliding frame; the inner wall of the sliding sleeve block and near its bottom end is fixedly installed with a hinge shaft, the outer wall of each hinge shaft is rotatably connected to a hinge sleeve rod, and the inner wall of the hinge sleeve rod is rotatably connected to a positioning shaft away from the hinge shaft; one end of the positioning shaft is installed with a hinge block, and the hinge block is slidably connected to the lower cover, the two positioning shafts are fixedly connected to the hinge block, and a lateral pressure sensor is fixedly installed on the lower surface of the hinge block, and the lateral pressure sensor is fixedly connected to the lower cover. The center point of the hinge shaft is higher than the center point of the positioning shaft, and the two positioning shafts are symmetrically arranged about the middle of the hinge block.

[0011] When the present technical solution is in use, when the push plate is squeezed by the side of a heavy object, the push plate will drive the connection block to be squeezed, the pressure column squeezes the rubber block along the inside of the sleeve groove block, and the rubber block is compressed and deformed after being stressed, and then the push plate carries the push bar to approach the sensing shaft, the sliding sleeve block moves left along the outer wall of the support rod, and the sliding sleeve block drives the hinge shaft to move right at the same time, the hinge shaft drives the hinge sleeve rod to move right, the positioning shaft drives the hinge block to move downward, and the lower cover supports the lateral pressure sensor, which can sense the pressure value. When the pressure value sensed by the lateral pressure sensor exceeds the pressure value set by the wireless controller, the transmission motor drive is started through the wireless controller.

[0012] The present invention has the following advantages: 1. The present invention uses a timely disengagement mechanism at the top. When a heavy object is pressed against the upper surface of the arc groove plate, when the pressure value sensed by the top pressure sensor exceeds the disengagement pressure value set by the wireless controller, the reduction motor drives the linkage screw to rotate, and the linkage screw drives the sleeve block to move right under the action of the thread transmission force, and the guide frame drives the sliding column to move right along the circular arc path, and the guide column drives the arc bar to move right along the circular arc path, and the arc bar drives the push plate to move right along the circular arc path. The two push plates can push the heavy object pressed against the upper surface of the arc groove plate to move until the heavy object no longer contacts the upper surface of the arc groove plate, and can timely realize the disengagement operation of the heavy object on the upper surface of the arc groove plate, so as to avoid the heavy object from continuously pressing the arc groove plate and causing the top of the upper cover to be continuously damaged by force, and the optical cable joint box is not easily deformed and damaged, thereby greatly improving the compressive and durable strength of the optical cable joint box.

[0013] 2. The present invention utilizes the timely side disengagement mechanism. When the push plate is squeezed by the lateral heavy object, the transmission motor drives the bidirectional screw to rotate positively inside the support frame, and the distance between the two sleeve groove blocks becomes larger. The pressure column causes the connecting block to move right synchronously, and the connecting block drives the supporting block to move right. The push plate will synchronously drive the two push strips to move right, and the other push plate moves left, so that the heavy object on the side of the push plate can be at a larger distance from the side of the lower cover. The transmission motor is started to drive the bidirectional screw to reverse, and the two push plates are close to each other, so that the push plate and the side heavy object can be completely separated, and the side heavy object is prevented from continuously squeezing the push plate. When the side of the lower cover is squeezed by the heavy object, the side heavy object can be quickly separated, so that the side of the lower cover is prevented from being continuously squeezed by the heavy object, and the lower cover is prevented from being squeezed and damaged, thereby greatly improving the compressive and durable strength of the optical cable junction box, which not only enhances the compressive strength, but also has better anti-damage performance.

[0014] 3. The present invention uses a double-sided sensing assembly. When the push plate is squeezed by a heavy object on the side, the push plate will drive the connection block to be squeezed, the pressure column will squeeze the rubber block along the inside of the sleeve groove block, the support block will drive the slide bar to move, and the slide bar will slide along the inner wall of the sleeve block, so that the push plate carries the push bar to approach the sensing shaft, the sliding sleeve block moves left along the outer wall of the support rod, and the sliding sleeve block drives the hinge shaft to move right at the same time, and the positioning shaft drives the hinge block to move downward. When the pressure value sensed by the lateral pressure sensor exceeds the pressure value set by the wireless controller, the transmission motor drive is started through the wireless controller, so that it can be known in time that there is a heavy object squeezing the side of the lower cover, and the heavy object can be detached in time to avoid continuous squeezing of the side of the lower cover, greatly improving the compressive and durable strength of the optical cable junction box.

[0015] According to the mutual influence of the above-mentioned multiple effects, the two push plates are first able to push the heavy objects squeezed on the upper surface of the arc trough plate to move until the heavy objects no longer contact the upper surface of the arc trough plate, and then the positioning shaft drives the hinge block to move downward. When the pressure value sensed by the lateral pressure sensor exceeds the pressure value set by the wireless controller, the heavy objects on the side of the push plate are finally able to have a large distance from the side of the lower cover, and then the push plate and the heavy objects on the side are completely separated. In summary, it is possible to automatically and timely know that the arc trough plate is squeezed by a heavy object, and it is also possible to timely know that the side of the lower cover is squeezed by a heavy object, so that the squeezed top heavy objects can be automatically separated, and the side heavy objects can be automatically separated, and the squeezing time of the heavy objects is greatly shortened, thereby avoiding damage caused by continuous squeezing, and thus greatly improving the compressive and durable strength of the optical cable junction box.

Then the guide column 11 drives the arc bar 12 to move right along the arc path, and the arc bar 12 drives the push plate 13 to move right along the arc path, and the other push plate 13 moves left along the arc path, and the two push plates 13 can push the weight squeezed on the upper surface of the arc slot plate 3 to move until the weight no longer contacts the upper surface of the arc slot plate 3, so that the weight and the arc slot plate 3 can be separated.

[0035] Step three, during double-sided heavy object sensing, when the push plate 37 is squeezed by the side of the heavy object, the push plate 37 will drive the connecting block 33 to be squeezed, the connecting block 33 will drive the pressure column 31 to be squeezed, the pressure column 31 will squeeze the rubber block 32 along the inside of the sleeve groove block 30, and the rubber block 32 will be compressed and deformed after being stressed, and at the same time, the connecting block 33 will drive the support block 34 to move, the support block 34 will drive the slide rod 35 to move, and the slide rod 35 will slide along the inner wall of the sleeve block 36, and the sleeve groove block 30 can provide a stable supporting force for the sleeve block 36, and the sleeve block 36 will guide the slide rod 35, so that the pressure column 31 can be stably squeezed inside the sleeve groove block 30. Then, the push plate 37 carries the push strip 38 and approaches the sensing shaft 39, and the sensing shaft 39 drives the sliding sleeve 40 to move left, and the sliding sleeve 40 moves left along the outer wall of the support rod 41, and the sliding sleeve 40 moves right along the inner wall of the sliding frame 42, and the sliding sleeve 40 drives the hinge shaft 47 to move right at the same time, and the hinge shaft 47 drives the hinge sleeve rod 43 to move right, and the bottom end of the hinge sleeve rod 43 drives the positioning shaft 44 to move downward, and the positioning shaft 44 drives the hinge block 45 to move downward, and the hinge block 45 squeezes the sensing end of the lateral pressure sensor 46, so that the lower cover 2 supports the lateral pressure sensor 46, and the lateral pressure sensor 46 can sense the pressure value. When the pressure value sensed by the lateral pressure sensor 46 exceeds the pressure value set by the wireless controller 26, the transmission motor 29 is driven by the wireless controller 26, and it can be known in time that the push plate 37 is squeezed laterally by a heavy object.

[0036] Step 4: When the side is disengaged in time, the transmission motor 29 drives the bidirectional screw 28 to rotate forward inside the support frame 27, and at the same time, the bidirectional screw 28 drives the sleeve slot block 30 to move right under the action of the thread transmission force, and the other sleeve slot block 30 moves left under the action of the thread transmission force. The distance between the two sleeve slot blocks 30 increases, the sleeve slot block 30 drives the rubber block 32 to move right, the rubber block 32 drives the pressure column 31 to move right, the pressure column 31 makes the connection block 33 move right synchronously, and the connection block 33 drives the support block 34 to move right, and the support block 34 drives the slide bar 35 to move right, and the sleeve slot block 30 makes the sleeve block 36 move right. In this way, the connection block 33 drives the push plate 37 to move right, and the push plate 37 will synchronously drive the two push strips 38 to move right, while the other push plate 37 moves left. In this way, the push plate 37 can move the heavy objects on the side to the right and push them away, so that the heavy objects on the side of the push plate 37 can be separated from the side of the lower cover 2 by a large distance.

[0037] Then, the transmission motor 29 is started to drive the bidirectional screw 28 to reverse, and the bidirectional screw 28 drives the two sleeve groove blocks 30 to approach each other under the action of the thread transmission force. At the same time, the sleeve block 36 drives the rubber block 32 to make the pressure column 31 move left, and the pressure column 31 drives the connecting block 33 to move left. The connecting block 33 drives the push plate 37 to move left, and the other push plate 37 moves right. In this way, the two push plates 37 are close to each other, which can make the push plate 37 and the side weights completely separated, avoiding the side weights from continuously squeezing the push plates 37. When the side of the lower cover 2 is squeezed by the weights, it is known in time that the side weights can be quickly separated.
