Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a bridge device for communication cables. Background Technique

[0002] Communication cables are usually supported and protected by cable trays. A cable tray is a structure, usually made of metal or plastic materials, for supporting and protecting cables. The cable tray can be installed on walls, ceilings or floors, and is suitable for indoor or outdoor cable installation. It effectively supports and protects cables, prevents damage or interference, and facilitates the management of cable wiring and connection. In a communication system, a cable tray is a common accessory for supporting and managing various types of communication cables;

[0003] However, when the cable is routed, problems may occur at the right-angle bends of the cable tray. Since the routing angle of the cable changes suddenly, it will cause a large frictional force. In addition, the contact between the cable and the surface of the cable tray may increase the difficulty of wiring. Excessive force may damage the fixed end of the cable tray and the wall, resulting in the problem of the cable tray falling. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the utility model.

One end of the cable tray is connected to a support member, and the other end of the support member is fixed to the wall. It is characterized in that: a guiding component is provided at the corner of the cable tray. The guiding component includes a fixing member and a rolling member. The fixing member is arranged at the corner of the cable tray, and the rolling member is arranged on the fixing member, and its surface rolls relative to the surface of the cable in friction. When rolling relative to each other in friction, the surface of the cable gradually contacts the concave-convex surface of the rolling member from bottom to top.

[0006] Based on the above technical solutions, the utility model can be further improved as follows.

[0007] As a preferred solution of the bridge device for communication cables of the utility model, wherein: one end of the support member is a support frame, the support frame is connected to the cable tray, and the other end of the support member is a gasket, and the gasket is arranged on the support frame and fixed to the wall.

[0008] As a preferred embodiment of the cable tray device for communication cables of the present utility model, wherein: the concave-convex surface of the rolling member is a spiral groove formed on the roller shaft, and the surface of the cable is in contact with the spiral groove, and the roller shaft is arranged on the fixing member.

[0009] As a preferred embodiment of the cable tray device for communication cables of the present utility model, wherein: a shaft rod is provided at the center of the roller shaft, an extension block is provided on the shaft rod and is connected to the arc-shaped frame of the fixing member, and the number of the roller shafts is several.

[0013] As a preferred embodiment of the cable tray device for communication cables of the present utility model, wherein: the two sliders are connected by a connecting block, a contact plate is provided on the connecting block, and the contact plate is connected to the surface of the cable tray.

[0014] The beneficial effects of the present utility model are as follows: When the cable is routed, resistance will be encountered, increasing the construction difficulty. Excessive pulling of the cable may cause the fixing part between the cable tray and the wall to become loose. To reduce these problems, fixing members can be installed at the turning points of the cable tray, and rolling members can be installed at appropriate positions. When the cable is pulled, rolling friction is generated between the rolling member and the cable, reducing the resistance on the cable. At the same time, the concave-convex surface of the rolling member will guide the cable to move upward, lifting the cable at the turning point, reducing the contact between the cable in the area with greater resistance and the receiving groove. This facilitates the routing of the cable, reduces the pulling force, prevents the fixing part between the cable tray and the wall from becoming loose, and plays a protective role.

Detailed implementation manners

[0024] To make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. Embodiment

[0027] Refer to Figures 1 to 6, which is an embodiment of the present utility model. This embodiment provides a bridge device for a communication cable, including a bridge 100 and a receiving groove 100a on the bridge 100 for carrying the cable. One end of the bridge 100 is connected to a support member 101, and the other end of the support member 101 is fixed to the wall. A guiding component 200 is provided at the corner of the bridge 100. The guiding component 200 includes a fixing member 201 and a rolling member 202. The fixing member 201 is arranged at the corner of the bridge 100, and the rolling member 202 is arranged on the fixing member 201, and its surface relatively rolls and rubs against the surface of the cable. During the relative rolling friction, the surface of the cable gradually comes into contact with the concave-convex surface of the rolling member 202 from bottom to top;

[0028] Specifically, the bridge 100 plus the provided receiving groove 100a is a trough-type bridge. The bridge 100 is fixed to the wall or roof through the support member 101. The receiving groove 100a arranges the cable lines. However, due to the change in direction at the turning of the bridge 100, the cable lines will encounter great resistance during wiring, increasing the construction difficulty. If the cable lines are pulled excessively, the fixing part between the bridge and the wall will become loose. By installing the fixing member 201 at the turning of the bridge 100 and installing the rolling member 202 at a suitable position on the fixing member 201, when pulling the cable lines, the rolling member 202 and the cable lines roll and rub, greatly reducing the resistance on the cable. At the same time, the concave-convex surface on the rolling member 202 will drive the cable to move upward to the upper part of the rolling member 202, lifting the cable located at the turning of the bridge 100, greatly reducing the contact between the cable and the receiving groove 100a in the area with greater resistance, thus facilitating the wiring of the cable, reducing the resistance and then reducing the pulling force of the cable, preventing the fixing part between the bridge and the wall from becoming loose, and playing a protective role.

[0029] Exemplarily, as Figure 1 shown, one end of the support member 101 is a support frame 101a, the support frame 101a is connected to the bridge 100, the other end of the support member 101 is a gasket 101b, the gasket 101b is arranged on the support frame 101a and is fixed to the wall. The bridge 100 can be fixed to the wall or roof by matching the screw and the gasket 101b through drilling holes in the wall;

[0030] Exemplarily, as Figures 1 - 6 shown, in order to realize that the concave-convex surface on the rolling member 202 drives the cable to move upward to the upper part of the rolling member 202, the concave-convex surface of the rolling member 202 is a spiral groove 202a-1 opened on a roller 202a. The surface of the cable contacts with the spiral groove 202a-1. When the spiral groove 202a-1 contacts with the surface of the cable, it gradually drives the cable to move upward while pulling the cable, thus reducing the resistance when pulling the cable;

[0031] To achieve the rotation of the rolling member 202, so as to realize the rolling friction between the rolling member 202 and the surface of the cable, the roller 202a is arranged on the fixing member 201. A shaft rod 202b is provided at the axis of the roller 202a. An extension block 202c is provided on the shaft rod 202b and is connected to the arc-shaped frame 201a of the fixing member 201. And the number of the rollers 202a is several, and the rollers 202a can be reasonably installed according to the actual situation to cooperate with the cable to route at the turning of the cable tray 100;

[0032] To install the roller 202a on the cable tray 100, the number of the arc-shaped frames 201a connected is two, and they are connected by a connecting rod 201b. Bridge connectors 201c are provided at both ends of the arc-shaped frame 201a. The arc-shaped frame 201a is arranged at the corner of the cable tray 100 through the bridge connectors 201c. Universal holes 201a-1 are equidistantly arranged on the outer surface of the arc-shaped frame 201a. The universal holes 201a-1 facilitate the installation of the bridge connectors 201c on the arc-shaped frame 201a and the installation of the roller 202a on the arc-shaped frame 201a through the extension block 202c;

[0033] To enable the arc-shaped frame 201a to be better and more conducive to the roller 202a being arranged at a suitable position at the turning of the cable tray 100, the bridge connector 201c includes a connecting block 201c-1, a contact plate 201c-2 and a slider 201c-3. The slider 201c-3 is sleeved on the arc-shaped frame 201a. The number of the sliders 201c-3 is two. The limiting holes 201c-3a opened on the sliders 201c-3 are matched with the universal holes 201a-1. The two sliders 201c-3 are connected by a connecting block 201c-1. A contact plate 201c-2 is provided on the connecting block 201c-1. The contact plate 201c-2 is connected to the surface of the cable tray 100. The slider 201c-3 can slide within a certain range at both ends of the arc-shaped frame 201a and is locked by screws through the universal holes, so as to facilitate the installation of the arc-shaped frame 201a at the turning of the cable tray 100. Coupled with the fact that the roller 202a is also locked by screws through the universal screws, the cooperation of the two can make the roller 202a in a reasonable position at the turning of the cable tray 100, so that the roller 202a can play the most ideal effect.
