Description

Technical Field

[0001] The present invention relates to the field of cable tray connectors, and in particular to an adjustable cable tray connector. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supports and installation accessories. The cable trays can be erected independently in buildings or attached to various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts need to be galvanized and installed in the open air outside the building. Patent: CN216904136U discloses a connector for a cable tray, comprising a supporting plate, a limiting frame and a hanging frame, wherein the supporting plate comprises a plate body and an anti-slip pad, the anti-slip pad is symmetrically arranged on the upper end surface of the plate body, and the anti-slip pad is fixedly connected to the plate body, the limiting frame is symmetrically arranged on the upper end surface of the plate body, and the limiting frame is horizontally slidably connected to the plate body, the hanging frame is symmetrically arranged on both sides of the plate body, and the hanging frame is rotatably connected to the plate body, ensuring that the limiting frame can be stably installed through the plate body when a user needs to use it, and at the same time, by providing a guide groove on the plate body, it is ensured that the limiting frame can be stably installed and used by a bolt rod, and it is also convenient for the user to flexibly adjust the spacing between the limiting frames on both sides, ensuring that the connector can be used in conjunction with cable trays of different sizes, and at the same time, by setting the connecting plate, it is convenient for the user to fix the vertical plate and the cable tray to each other by bolts; The spacing adjustment method of the two limit frames in the above technology is complicated and needs to be fixed by bolts and nuts, which makes it inconvenient to move the position. In addition, the lifting ring in the above technology is not convenient for storage and placement, and the entire device is not convenient for folding and storage. It needs to be disassembled for storage, which is inconvenient to use and needs to be improved. For this reason, we propose an adjustable cable tray connector. Summary of the Invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a method for facilitating control of the distance between two limiting frames; another purpose of the present invention is to provide a method for facilitating storage and placement.

[0004] Technical solution: An adjustable cable tray connector includes a support plate, wherein the front of the upper surface of the support plate is symmetrically provided with adjustment slots, and the front surface of the support plate is provided with notches, wherein the notches are connected to opposite sides of the two adjustment slots; A bidirectional screw is provided on the inner side of the adjusting groove, and the two ends of the bidirectional screw are rotatably connected to the opposite sides of the inner sides of the two adjusting grooves through a rotating shaft. The outer side wall of the bidirectional screw and the inner sides of the two adjusting grooves are threadedly installed with a threaded sleeve, and the top of the threaded sleeve is fixedly connected to a moving bar, and a limiting frame is provided above the moving bar. The lower sides of the two limiting frames on the opposite sides are rotatably connected to the opposite sides of the two moving bars through a hinge.

[0005] Furthermore, the outer side wall of the bidirectional screw is fixedly connected to the inner side of the recess with an anti-slip sleeve.

[0006] Furthermore, a sliding groove is symmetrically opened at the rear of the upper surface of the supporting plate, and the lower surface of the movable bar is located inside the sliding groove and is fixedly connected to a limiting block.

[0007] Furthermore, a T-shaped slot is provided inside the support plate, the top of the T-shaped slot passes through the upper part of the support plate, and an anti-slip pad is opened and closed inside the T-shaped slot.

[0008] Furthermore, shrinkage cavities are symmetrically opened on both sides of the support plate, and a connecting cavity is fixedly connected between the two adjacent shrinkage cavities. The interior of the shrinkage cavity is fixedly connected to a fixing bar, and the outer wall of the fixing bar is slidably connected to a hanging ring, and a spring is fixedly connected between the hanging ring and the fixing bar.

[0009] Furthermore, the opposite sides of the two front and rear opposite rings are fixedly connected to a connecting strip on the inner side of the connecting cavity, a through-type toggle groove is provided on the inner upper surface of the connecting cavity, and the upper surface of the connecting strip is fixedly connected to a toggle block on the inner side of the toggle groove.

[0010] Furthermore, opposite sides of the two limiting frames are fixedly connected with shaft columns, and the outer side walls of the shaft columns are rotatably connected with blocking bars through rotating shafts.

[0011] Beneficial effects: The synergistic effect of the bidirectional screw and the threaded sleeve allows the spacing of the limit frames to be adjusted by manually rotating the anti-slip sleeve at the notch, making it easy to apply to limit installation under different conditions. Compared with the existing technology of positioning and adjusting by tightening bolts, the operation is simpler and more convenient. The anti-skid pad can play an anti-skid effect and ensure the installation stability. The anti-skid pad is easy to install through snap-on installation and easy to disassemble and replace, avoiding the problem of the anti-skid effect being deteriorated due to wear and tear after long-term use; In normal state, the lifting ring is retracted inside the shrinkage cavity under the pull of the spring, which is convenient for storage. When it needs to be hoisted, the lifting ring can be pushed out of the shrinkage cavity by pushing the toggle block to slide along the inner side of the toggle slot, which makes it easy to install the lifting rope for hoisting. When the limit frame is not in use, the baffle on the outer wall of the shaft column can be rotated to a horizontal state. At this time, the hinge pad between the limit frame and the movable bar is unobstructed. At this time, the limit frame can be rotated along the hinge point to a horizontal state, reducing the overall space occupied by the device and facilitating storage and placement.
