Description

Technical Field

[0001] This utility model belongs to the field of cable technology, and in particular relates to a cable joint protection device for electrical engineering. Background Technology

[0002] Cables are a general term for items such as optical fibers and electrical cables. Cables have many uses, primarily for control installation, equipment connection, and power transmission, making them a common and indispensable part of daily life. Because cables are live, their installation requires special care.

[0003] According to a public disclosure of an electrical engineering cable protection device (CN 213879234U), it includes an electrical engineering cable, a protective fixing frame, and an angle adjustment fixing device. The protective fixing frame is cylindrical, and the angle adjustment fixing device is located inside the protective fixing frame. The electrical engineering cable passes through a cable fixing hole and the angle adjustment fixing device. The angle adjustment fixing device includes a rotating shaft, a rotating connecting gear, a driving rotating gear, a rotating connecting rod, a rotating fixing handle, a connecting block, and a cable bending moving block. The protective fixing frame, the driving rotating gear, the rotating connecting gear, and the rotating connecting rod are connected by the rotating shaft. The electrical engineering cable passes through cable fixing hole one and cable fixing hole two. This utility model belongs to the field of electrical engineering equipment technology, specifically an electrical engineering cable protection device that can accurately and safely adjust the bending curvature of the cable when it needs to be bent at a certain angle, ensuring that the cable is not damaged due to excessive bending.

[0004] In the aforementioned application, the rotating gear, rotating connecting gear, and rotating connecting rod are connected by a rotating shaft. The cable through the cable fixing hole one and the cable fixing hole two makes it difficult to fix the cable joint during the winding process, resulting in the cable becoming loose in the storage state. This needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a cable joint protection device for electrical engineering, which solves the existing problems through the design of the joint protection device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a cable joint protection device for electrical engineering, including a take-up roller and a blocking roller. Two blocking rollers are provided. One end of each blocking roller is penetrated by one end of the take-up roller and is rotatably connected to one end of the take-up roller. Rotating handles are fixedly connected to both ends of the take-up roller. A joint protection device is provided on the inner side of the blocking roller.

[0008] The joint protection device includes an annular groove, one end of which is opened on the inner side of the blocking roller. A semi-circular arc strip is slidably connected inside the annular groove. A hinge block is hinged to one end of the semi-circular arc strip. A clamping block is fixedly connected to one end of the hinge block. A connecting arc rod is fixedly connected to the top of the semi-circular arc strip. One end of the connecting arc rod is fixedly connected to the top of another semi-circular arc strip. A blocking plate is fixedly connected inside the annular groove. A sliding strip is fixedly connected to the side of the connecting arc rod.

[0009] Furthermore, a rotating shaft is rotatably connected to the side of the sliding bar, and a limiting plate is fixedly connected to one end of the rotating shaft. A limiting strip is fixedly connected to the side of the blocking roller. When the sliding bar is adjusted to the appropriate position, the operator presses the limiting plate down 90°, so that the limiting plate is blocked by both sides of the limiting strip, thereby limiting the two sides of the limiting plate.

[0010] Furthermore, multiple limiting strips are provided and arranged circumferentially on the side of the blocking roller. This design increases the selectivity of the limiting plate's limiting position.

[0011] Furthermore, a cable groove is formed on the circumferential surface of the take-up roller, and the diameter of the cable groove is set to 5cm-7cm. This design conforms to most cable diameter standards and is suitable for most cables.

[0012] Furthermore, the connector protection device is provided in two sets, symmetrically arranged along the vertical central axis of the take-up roller. This design enhances the device's ability to secure the cable connector.

[0013] Furthermore, the inclined surface of the blocking plate is located on the displacement trajectory of the clamping block. This design ensures that the clamping block rotates when it displaces and squeezes the blocking plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model utilizes the interplay of components such as clamping blocks and connecting arc rods within the connector protection device. This allows two hinged blocks to rotate, causing two clamping blocks to slide within the annular groove. During this sliding process, the two clamping blocks contact corresponding blocking plates and rotate on their own. Operators can adjust the rotation angle of the two clamping blocks according to the diameter and length of the cable, thereby securing the other connector of the cable by inserting it under the two clamping blocks. This prevents the cable from becoming loose during storage and protects the cable connector.

[0016] 2. This utility model utilizes the cooperation of components such as the limiting plate and limiting strip inside the connector protection device. When the sliding strip is adjusted to the appropriate position, the operator presses the limiting plate down 90°, causing the limiting plate to be blocked by both sides of the limiting strip, thus limiting the two sides of the limiting plate and further enhancing the fixing effect of the cable connector.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model is a cable joint protection device for electrical engineering, including a take-up roller 1 and a blocking roller 2. There are two blocking rollers 2. One end of the two blocking rollers 2 is penetrated by one end of the take-up roller 1 and is rotatably connected to one end of the take-up roller 1. Rotating handles 3 are fixedly connected to both ends of the take-up roller 1. A joint protection device 4 is provided on the inner side of the blocking roller 2.

[0027] The joint protection device 4 includes an annular groove 41, one end of which is opened on the inner side of the blocking roller 2. A semi-circular arc strip 42 is slidably connected inside the annular groove 41. A hinge block 43 is hinged to one end of the semi-circular arc strip 42. A clamping block 44 is fixedly connected to one end of the hinge block 43. A connecting arc rod 45 is fixedly connected to the top of the semi-circular arc strip 42. One end of the connecting arc rod 45 is fixedly connected to the top of another semi-circular arc strip 42. A blocking plate 46 is fixedly connected inside the annular groove 41. A sliding strip 47 is fixedly connected to the side of the connecting arc rod 45.

[0028] A rotating shaft 48 is rotatably connected to the side of the sliding strip 47. One end of the rotating shaft 48 is fixedly connected to a limiting plate 49, and a limiting strip 410 is fixedly connected to the side of the blocking roller 2. When the sliding strip 47 is adjusted to the appropriate position, the operator presses the limiting plate 49 down 90°, so that the limiting plate 49 is blocked by both sides of the limiting strip 410, thereby limiting both sides of the limiting plate 49.

[0029] Multiple limit bars 410 are provided and arranged circumferentially on the side of the blocking roller 2. This design increases the selectivity of the position where the limit plate 49 is limited.

[0030] The take-up roller 1 has a cable groove 5 on its circumferential surface, and the diameter of the cable groove 5 is set to 5cm-7cm. This design conforms to most cable diameter standards and is suitable for most cables.

[0031] Two sets of connector protection devices 4 are provided, and they are symmetrical to each other along the vertical central axis of the take-up roller 1. This design increases the device's ability to secure cable connectors.

[0032] The inclined surface of the baffle plate 46 is located on the displacement trajectory of the clamping block 44. This design ensures that the clamping block 44 rotates when it displaces and presses against the baffle plate 46.

[0033] One specific application of this embodiment is as follows: After the cable is laid, it needs to be wound up and collected. Generally, a winding roller 1 is used to wind and store it for future laying. During use, the cable end can be placed into the cable groove 5, and the rotating handle 3 can be turned to drive the winding roller 1 to wind up the cable. When the other end of the cable is wound up, the conventional winding roller 1 is difficult to fix the other end of the cable, which can cause the cable to loosen when the winding roller 1 rolls during storage. This device can slide the sliding bar 47 after the cable end is wound up, which can drive the connecting arc rod 45 to rotate. The connecting arc rod 45 rotates, causing the two semi-circular arc strips 42 to rotate. The rotation of the two semi-circular arc strips 42 is transmitted through the rotation of the two hinge blocks 43. The rotation of the two hinge blocks 43 causes the two clamping blocks 44 to slide inside the annular groove 41. During the sliding process, the two clamping blocks 44 will contact the corresponding two blocking plates 46 and rotate on their own. The staff can adjust the rotation angle of the two clamping blocks 44 according to the diameter and length of the cable, so that the other connector of the cable can be locked under the two clamping blocks 44 for fixation, thereby preventing the cable from coming loose during storage and protecting the cable connector.

[0034] After the sliding bar 47 is adjusted to the appropriate position, the staff presses down on the limiting plate 49, so that the limiting plate 49 is blocked by the two sides of the limiting bar 410, thus limiting the two sides of the limiting plate 49.
