Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and particularly relates to a bridge connector with adjustable angle. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, cantilever arms and installation accessories, etc. A cable tray is a tool for facilitating the management of lines and sorting out lines and some pipelines, enabling numerous lines in a building to be arranged neatly and orderly, and also playing a role in supporting a large number of lines, making the appearance of a large number of cumbersome lines more beautiful. The cable tray in a building can be erected independently or laid on various building (structure) buildings and pipe gallery brackets.

[0003] When constructing a cable tray, various connectors are often required according to the length of the laid cable or the requirement of direction change. For example, a straight wire duct for increasing the length and elbow wire ducts with different angles for changing the direction. However, the angles of these connectors are fixed and cannot be adjusted according to actual working needs, resulting in poor applicability and flexibility. Therefore, when constructing a cable tray, various connectors with different angles need to be continuously replaced according to different on-site situations, leading to a cumbersome working process and wasting time in searching for connectors with appropriate angles. Content of the Utility Model

[0004] In order to overcome the problem that the prior art cannot be adjusted according to actual working needs, resulting in poor applicability and flexibility, and thus when constructing a cable tray, various connectors with different angles need to be continuously replaced according to different on-site situations, leading to a cumbersome working process and wasting time in searching for connectors with appropriate angles, the utility model provides a bridge connector with adjustable angle. The technical solution is as follows:

[0005] A bridge connector with adjustable angle includes a first connecting frame, a second connecting frame hinged to the first connecting frame, and a connecting plate connecting the first connecting frame and the second connecting frame. The cross-sections of the first connecting frame and the second connecting frame are both U-shaped. Positioning bolts are arranged at one ends of the first connecting frame and the second connecting frame that are close to each other. The connecting plate is located on the outer side surfaces of the connecting frames, and an arc-shaped hole is formed in the connecting plate. The positioning bolts are arranged in the arc-shaped hole and can slide along the arc-shaped hole. The connecting plate is used to connect the first connecting frame and the second connecting frame and fix the included angle between the two.

[0006] Furthermore, connecting plates are arranged on both outer side surfaces of the first connecting frame and the second connecting frame.

[0007] Furthermore, connection reinforcement components are provided on both outer sides of the first connecting frame and the second connecting frame, and the reinforcement components can enhance the angle fixing effect between the first connecting frame and the second connecting frame.

[0008] Furthermore, the connection reinforcement component includes a first connecting rod hinged to the first connecting frame and a second connecting rod hinged to the second connecting frame. The first connecting rod is connected to the second connecting rod, and mutually matching sawteeth are provided on the surfaces of the first connecting rod and the second connecting rod that are in contact with each other. A sliding sleeve is slidably arranged on the first connecting rod and the second connecting rod together. A fastening screw is provided at the top or bottom of the sliding sleeve. When not in use, the sliding sleeve is located on the first connecting rod or the second connecting rod. After the angles of the first connecting frame and the second connecting frame are adjusted, the sawteeth on the first connecting rod and the second connecting rod are meshed and connected. Then, the sliding sleeve is slid to the part where the sawteeth on the first connecting rod and the second connecting rod are meshed, and the sliding sleeve is fixed by using the fastening screw, and at the same time, the first connecting rod and the second connecting rod are stably connected to prevent disconnection.

[0009] Furthermore, a rubber protection cap is sleeved on the end of the positioning bolt located inside the first connecting frame and the second connecting frame, which effectively reduces the friction between the cable inside the device and the positioning bolt, thereby reducing the wear of the cable.

[0010] Furthermore, hinges are provided at one end of the bottom surfaces of the first connecting frame and the second connecting frame that are close to each other, and the first connecting frame and the second connecting frame are hinged through the hinges.

[0011] Furthermore, bevel cuts are provided at one end of the first connecting frame and the second connecting frame that are close to each other, and the connecting plate is trapezoidal, and the side length of the upper end of the connecting plate is greater than the side length of the lower end. The shape of the connecting plate is adapted to the shape of the bevel cut, and the first connecting frame, the second connecting frame and the connecting plate of this shape are suitable for the wire routing situation of acute angles.

[0012] Furthermore, the connecting plate is semicircular, and the arc-shaped hole is divided into two segments with the same center of the circle. The first connecting frame, the second connecting frame and the connecting plate of this shape are suitable for the wire routing situation of obtuse angles.

[0013] The beneficial effects of the technical solution provided by the present utility model are as follows: The present utility model can be quickly adjusted according to the turning angle required by the on-site bridge through the hinged first connecting frame, second connecting frame and the connecting plate connecting the first connecting frame and the second connecting frame, so that the bridge connector can cope with different turning angles, improving flexibility and applicability, and correspondingly saving construction time and reducing time costs;

[0014] The present utility model can meet the different turning angle requirements of the bridge for upward turning and downward turning through different connector forms;

[0015] The utility model also strengthens the connection between the first connecting frame and the second connecting frame through a connection reinforcement component, so that after adjusting the corresponding angle, the fixation is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
