Description

Technical Field

[0001] This application relates to the technical field of cable trays, and in particular to a cable tray connector with an adjustable connection angle. Background Technology

[0002] With the rapid development of the economy, the demand for electricity in all aspects of daily life and industrial production is increasing. To meet the electricity requirements of concentrated power consumption areas, cables are generally used for power transmission. To avoid visual pollution caused by various installed cables, and to ensure the safety of cable operation and prevent accidents caused by non-professionals coming into contact with cables, cable trays are generally used to install cables.

[0003] During cable tray installation, it is common to encounter cable trays at different angles being connected to each other. Currently, cable tray joints are used to connect cable trays at different angles. Existing cable tray joints only offer fixed angle bends of 30°, 45°, and 60°. In some cases, these bends cannot meet the requirements of on-site use, and it is necessary to have them custom-made by the on-site installers. This results in problems such as inconsistent cable tray joint specifications and long installation time for custom-made cable tray joints with specific angles.

[0004] To address the aforementioned technical problems, this application proposes a cable tray connector with standardized specifications and adjustable connection angle. Utility Model Content

[0005] In order to standardize cable tray specifications and enable cable trays to be connected at any angle, this application provides a cable tray connector with an adjustable connection angle.

[0006] This application provides a cable tray connector with an adjustable connection angle, employing the following technical solution: it includes multiple connectors connected to the cable tray and a connecting cavity for connecting different connectors; the connecting cavity includes an upper mounting plate and a lower mounting plate, the upper mounting plate and the lower mounting plate being arranged in parallel, and each of the upper mounting plate and the lower mounting plate having a plurality of mounting holes correspondingly formed, the mounting holes being arranged along a circular trajectory; the end of the connector near the connecting cavity is provided with a fastener, and the end of the connector is fixed by the fastener engaging with the mounting holes on the two mounting plates.

[0007] By adopting the above technical solution, multiple connectors are fixed to the connecting cavity through the mounting holes with fasteners. Since there are multiple mounting holes, the installation angle of the connectors can be selected at multiple angles to meet the connection requirements of the cable tray in different directions. The upper mounting plate and the lower mounting plate firmly clamp the ends of the connectors in the middle to achieve bidirectional force balance, avoid the twisting of the connectors caused by unilateral fixing, and ensure the stability of long-term use.

[0008] Preferably, the end of the connector is detachably fixed by fasteners engaging with mounting holes on the two mounting plates.

[0009] By adopting the above technical solution, the end of the connector can be detachably fixed by fasteners and mounting holes on the two mounting plates. On-site personnel can easily complete the splicing between the connector and the connecting cavity, saving installation time; at the same time, the angle and position of the cable tray can be flexibly adjusted.

[0010] Preferably, an arc-shaped plate is provided between the connector and the communicating cavity. One end of the arc-shaped plate is positioned corresponding to the mounting hole. The end of the arc-shaped plate is detachably fixed to the mounting plate, and the other end of the arc-shaped plate is fixed to the side wall of the connector. The arc-shaped plate forms a transition rounded corner between the connector and the communicating cavity. Each connector is provided with two arc-shaped plates, which are located on both sides of the connector respectively.

[0011] By adopting the above technical solution, the arc plate forms a transition rounded corner between the joint and the connecting cavity, which can eliminate the sharp edges of the traditional right-angle bend, allowing the cable to pass smoothly when threading or dragging, and reducing the risk of insulation layer scratches; the setting of two arc plates can protect the cable in all directions.

[0012] Preferably, the end of the arc-shaped plate near the mounting hole is designed as a cylindrical tube that runs vertically through the top and bottom. The fastener includes a double-ended bolt and a nut. The double-ended bolt passes through the mounting hole and the cylinder, and nuts are installed at both ends of the double-ended bolt for fixation.

[0013] By adopting the above technical solution, the end of the arc plate near the connecting cavity is designed as a cylinder, which further protects the cable and reduces the risk of insulation layer damage; the double-headed bolt passes through the mounting hole and the cylinder is fixed to the connecting cavity by the cooperation of the double-headed bolt and nut, which further strengthens the connection strength between the arc plate and the connecting cavity and prevents the arc plate from loosening.

[0014] Preferably, the mounting holes are evenly arranged along a circular trajectory, with one mounting hole spaced between the two arc-shaped plates on the same connector, and the two arc-shaped plates are symmetrically arranged along the central axis of the connector.

[0015] By adopting the above technical solution, the mounting holes are evenly arranged along the circumference of the mounting plate, so that the central angle formed by the line connecting two adjacent mounting holes and the center of the circle is the same, which makes it convenient for workers to quickly determine the installation angle by the number of mounting holes. The two arc-shaped plates are set with a mounting hole spaced apart and are symmetrically arranged along the central axis of the joint, which allows the operator to quickly determine the angle formed between the joints by the angle formed by the mounting hole between the two arc-shaped plates and the mounting hole between the two arc-shaped plates on the other joint with the center of the circle, which facilitates the installation of the joints and saves installation time.

[0016] Preferably, both the upper mounting plate and the lower mounting plate are circular plates, and the upper mounting plate and the lower mounting plate are the same size; the periphery of the connecting cavity is provided with an arc-shaped closed side plate that matches the contour of the mounting plate, and the length of the closed side plate is set to correspond to the arc-shaped outer contour length between two adjacent mounting holes. The two ends of the closed side plate are respectively fixed to the upper mounting plate and the lower mounting plate; the closed side plate is provided with multiple sections that close the area of ​​the connecting cavity except for the mounting joint.

[0017] By adopting the above technical solution, the circular design fits the trajectory of the mounting hole, saving production materials; after the cable is laid, the closed side plate is installed to seal the connecting cavity, which protects the cable and prevents dust; if heat dissipation of the cable is required, the closed side plate can be omitted.

[0018] Preferably, annular fixing plates are fixed at both ends of the closed side plate. The fixing plate at one end is attached to the side of the upper mounting plate away from the lower mounting plate, and the fixing plate at the other end is attached to the side of the lower mounting plate away from the upper mounting plate. The circumferential position of the fixing plate corresponds to the mounting hole. A double-ended bolt passes through the central hole of the fixing plate, and the fixing plate is fixed by a nut.

[0019] By adopting the above technical solution, the design of the fixing plate can avoid interfering with the connection between the arc plate and the connecting cavity, and its location on the outside of the connecting cavity facilitates the installation and fixing of the closed side plate.

[0020] Preferably, a support sleeve and a connecting screw are provided at the center of the upper mounting plate and the lower mounting plate, respectively. The two ends of the support sleeve abut against the upper mounting plate and the lower mounting plate, respectively. The connector is inserted into the support sleeve, and the two ends of the connecting screw pass through the upper mounting plate and the lower mounting plate, respectively. Nuts are screwed onto the two ends of the connecting screw to fix the two mounting plates.

[0021] By adopting the above technical solution, and by setting support sleeves and connecting screws at the center positions of the upper mounting plate and the lower mounting plate, the overall strength of the connecting cavity is enhanced, loosening between the two mounting plates is prevented when the connecting cavity is under force, and the stability of long-term use is ensured.

[0023] By adopting the above technical solution, and by setting up a connecting cavity between the third mounting plate and the upper mounting plate, and setting up mounting holes, joints, arc plates and fasteners in the corresponding connecting cavity, multiple cable trays can be connected at any angle in three-dimensional space.

[0024] Preferably, it also includes a spring washer, which is sleeved on the double-ended bolt and clamped and fixed between the mounting plate and the nut.

[0025] By adopting the above technical solution, the spring pad prevents the double-headed bolts and nuts connecting the curved plate and the mounting plate from loosening due to vibration.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a connecting cavity consisting of an upper mounting plate, a lower mounting plate, and a connecting screw, multiple mounting holes evenly arranged around the circumference on the two mounting plates, a connector for connecting the cable tray, and an arc-shaped plate located between the connector and the connecting cavity, the arc-shaped plate can be fixed on the connecting cavity by being installed in different mounting holes, thereby realizing multi-angle installation of the connector; 2. The arc-shaped plate at the end of the joint can be detachably installed between the two mounting plates using double-headed bolts, allowing on-site personnel to easily complete the splicing between the joint and the connecting cavity, saving installation time; at the same time, it can flexibly adjust the angle and position of the cable tray turning, making it more suitable for on-site working conditions; 3. The mounting holes are evenly distributed around the circumference of the mounting plate, with one mounting hole spaced between two arc-shaped plates. The two arc-shaped plates are symmetrically arranged along the central axis of the joint, allowing operators to quickly determine the angle between the joints based on the angle formed by the mounting holes located between the two arc-shaped plates. This facilitates the installation of the joints and saves installation time. Attached Figure Description

[0032] The connecting cavity 2 includes an upper mounting plate 21, a lower mounting plate 22, a support sleeve 23, and a connecting screw 24.

[0033] The cross-sectional shape of connector 1 corresponds to the cross-sectional shape of the cable tray. A fixing hole is provided at the end of connector 1 near the cable tray. Connector 1 is fixed to the cable tray by bolts passing through the fixing hole. In this embodiment, the cross-sectional shape of connector 1 is set to be rectangular according to the cross-sectional shape of the cable tray. An arc plate 3 is provided at the end of connector 1 away from the cable tray. There are two arc plates 3. The two arc plates 3 are respectively formed by extending the side plates on both sides of connector 1 along their own length direction. The end of arc plate 3 away from connector 1 can be detachably installed between the upper mounting plate 21 and the lower mounting plate 22. The arc plate 3 forms a transition rounded corner between connector 1 and connecting cavity 2, eliminating the sharp corners of traditional right-angle bends, so that the cable can pass smoothly when threading or dragging, reducing the risk of insulation layer scratch.

The axes of the mounting holes 25 are perpendicular to the mounting plates, and the mounting holes 25 are evenly arranged around the circumference, so that the connector 1 can be installed on different mounting holes 25, realizing multi-angle adjustment between the two connectors 1 and meeting the connection requirements of the cable tray in different directions. In this embodiment, there are 12 mounting holes 25. A cylinder 4 is integrally provided at the end of the arc plate 3 away from the connector 1.

A mounting hole 25 is set between the cylinders 4 of the two arc-shaped plates 3 of the same connector 1, so that the operator can quickly determine the angle between the two connectors 1 by the angle formed by the mounting hole 25 between the two cylinders 4 and the mounting hole 25 between the two cylinders 4 on the other connector 1 and the center. This facilitates the installation of connector 1 and saves installation time.

The fixing piece 8 at one end of the closed side plate 7 is attached to the side of the upper mounting plate 21 away from the lower mounting plate 22, and the fixing piece 8 at the other end of the closed side plate 7 is attached to the side of the lower mounting plate 22 away from the upper mounting plate 21. The inner size of the fixing piece 8 is larger than the size of the mounting hole 25, and the center position of the fixing piece 8 corresponds to the center position of the mounting hole 25. There are two fixing pieces 8 at one end of the closed side plate 7, and the center positions of the two fixing pieces 8 correspond to the center positions of two adjacent mounting holes 25. The fixing pieces 8 pass through the double-ended bolts 5 and are fixed to the connecting cavity 2 by nuts 6. After the cable is laid, install the closed side plate 7 to seal the connecting cavity 2, which protects the cable and prevents dust. If heat dissipation of the cable is required, the closed side plate 7 can be omitted.

[0037] refer to Figure 1 and Figure 5 Depending on the actual situation, a third mounting plate 10 can be provided on the side of the upper mounting plate 21 away from the lower mounting plate 22. The upper mounting plate 21 and the third mounting plate 10 are fixed to each other by connecting screws 24 to form another communicating cavity 2. The shape and size of the third mounting plate 10 correspond to the upper mounting plate 21. The third mounting plate 10 is also provided with mounting holes 25. A connector 1 is detachably fixed between the third mounting plate 10 and the upper mounting plate 21. An arc-shaped plate 3 is fixed between the connector 1 and the third mounting plate 10. A closed side plate 7 is fixedly installed on the periphery of the third mounting plate 10 and the upper mounting plate 21. The three mounting plates, the connector 1 and the closed side plate 7 are connected into a whole by double-headed bolts 5 and nuts 6.
