Description

Technical Field

[0001] The utility model relates to the technical field of feeder installation equipment, in particular to a corner feeder chuck. Background Art

[0002] With the rapid development of modern communication technology, feeders, as important components for signal transmission, are increasingly used in various communication facilities, especially in base stations, indoor distribution systems, data centers, and other scenarios. In these scenarios, feeders often need to pass through various corners and bends during installation, and how to accurately and efficiently complete the corner bending of feeders has become a major challenge for construction workers.

[0003] Deficiencies of existing technology:

[0004] In the existing feeder installation technology, when construction workers encounter the need to bend the feeder during the installation process, they usually use manual bending to bend the feeder to the required angle, and then fix it to the wall with wire clips or other fixings at both ends of the corner. However, this bending method has many defects. First, when the number of feeders that need to be bent is large, or when they need to be bent at multiple locations, it is difficult to ensure that the angles of each bending point are accurate and consistent by manual bending, which will affect the overall aesthetics. Secondly, in the process of manual bending, due to the different materials and diameters of the feeder, it is easy for construction workers to cause the feeder to be damaged or even the internal wire core to be broken due to uneven force or excessive force, which will seriously affect the later signal transmission effect and the overall service life of the feeder. In addition, for feeders with higher wire skin hardness and toughness, construction workers need to spend a lot of physical strength and time to complete the bending work, which not only reduces construction efficiency, but also increases construction costs.

[0031] See also Figure 1-5As shown, the utility model provides a technical solution for a corner feeder chuck: a corner feeder chuck, comprising a chuck seat 1, a corner mechanism 2 for bending the feeder is centrally installed on the end face of the chuck seat 1, and a rotation positioning mechanism 3 for positioning the feeder is installed on both sides of the corner mechanism 2 on the end face of the chuck seat 1. The corner mechanism 2 includes an L-shaped groove 201, a bending frame 204 and two positioning rings 205. The L-shaped groove 201 is provided on the end face of the chuck seat 1, and both ends of the L-shaped groove 201 pass through the side wall of the chuck seat 1. A plurality of springs 202 are installed in the transverse groove of the L-shaped groove 201, and the upper end of the spring 202 is connected to a limit plate 203, and the limit plate 203 is slidably connected to the inner wall of the transverse groove of the L-shaped groove 201. The bending frame 204 is slidably connected in the transverse groove of the L-shaped groove 201 to push the feeder to bend. The bottom of the bending frame 204 is connected and positioned with the end face of the limit plate 203 by providing a one-way tooth meshing connection. Two positioning rings 205 are fixedly installed on the end face of the chuck seat 1 at one end of the L-shaped groove 201. The two positioning rings 205 are threadedly connected with a screw 206 to push the bending frame 204 to move in the L-shaped groove 201. The end of the screw 206 is provided with an external hexagonal head to facilitate the construction personnel to operate and rotate. When the feeder needs to be bent when passing through a corner, the chuck seat 1 is first fixed to the corner of the wall, and then the feeder is passed through the corresponding two rotation positioning mechanisms 3. Then, a bending frame 204 is inserted from the vertical groove end of the L-shaped groove 201, and the part of the feeder located on the chuck seat 1 passes through the front end of the bending frame 204. Then, the staff drives the screw 206 to rotate through a sleeve or a wrench, and the rotating screw 206 pushes the bending frame 204 forward along the two positioning rings 205, thereby driving the feeder to bend along the front end of the bending frame 204. During the movement of the bending frame 204, the limit plate 203 is subjected to the downward pressure of the one-way teeth, and then overcomes the elastic force of the spring 202 and slides downward a certain distance, so that the limit plate 203 is separated from the one-way teeth on the end face of the bending frame 204. After the bending frame 204 moves to the specified position and the feeder is bent, the feeder is first fixed by the rotating positioning mechanism 3, and the staff can take it out by rotating the screw 206 in the opposite direction. The bending frame 204 is limited by the limit plate 203 under the action of the one-way teeth, keeping the feeder in a tensioned state. Through the corner mechanism 2, the feeder can be accurately bent to a specified angle on the chuck seat 1. Compared with the traditional bending method, the positioning effect is more beautiful, and the method of using the screw 206 to promote the bending will not damage the line, thereby ensuring the signal transmission effect. For feeders with higher hardness and toughness, it also saves more physical effort.

[0032] The rotation positioning mechanism 3 includes a mounting groove 301, a positioning bolt 303 and a riding clamp 304. The mounting groove 301 is symmetrically arranged on the end face of the chuck seat 1 relative to the transverse groove of the L-shaped groove 201. A rotating seat 302 is movably arranged in the mounting groove 301. The rotating seat 302 can rotate in the mounting groove 301 and can also move up and down. The rotating seat 302 is located at one end inside the mounting groove 301 and on the upper wall of the mounting groove 301. The positioning bolt 303 is threadedly connected in the threaded groove on the chuck seat 1 and is located below the rotating seat 302. The riding clamp 304 is installed on the upper end of the rotating seat 302 by screws. The chuck seat 1 can be provided with a plurality of mounting grooves 301 and a rotating seat 302 according to actual use requirements. Before bending the feeder, first loosen the positioning bolt 303 so that the rotating seat 302 is separated from the surface teeth on the upper wall of the installation slot 301, and then rotate the rotating seat 302 according to the angle at which the feeder needs to be bent, and adjust the angle of the axis of the riding card 304 to set it. After the angle adjustment is completed, tighten the positioning bolt 303 so that the rotating seat 302 is re-positioned by the installation slot 301. When the feeder needs to pass through the riding card 304, first loosen the screws that fix the riding card 304, and then pass the wire ends of the feeder through the corresponding riding card 304 in turn. After the feeder is bent, tighten the screws, and the riding card 304 will position the feeder on the rotating seat 302. By rotating the positioning mechanism 3, the flexible setting of the feeder bending angle is realized, which further expands the application range of the angle feeder chuck, improves practicality and flexibility, and better meets the current construction application needs.

[0033] The vertical groove of the L-shaped groove 201 is opened at a height higher than the horizontal groove, so that the bending frame 204 can slide from the vertical groove end of the L-shaped groove 201 to the top of the limiting plate 203.

[0034] The propulsion end of the bending frame 204 is rotatably connected to a pulley 2041 , and the pulley 2041 can provide sufficient protection when the feeder moves at the front end of the bending frame 204 .

[0035] A positioning sleeve 2042 matching the end of the screw rod 206 is installed at one end of the bending frame 204 away from the pulley 2041. The screw rod 206 pushes the bending frame 204 to move in the positioning sleeve 2042 without slipping or dislocation, thereby improving construction efficiency.

[0036] The working principle of the utility model is as follows:

[0037] When using a corner feeder chuck of this embodiment, before bending the feeder, first loosen the positioning bolt 303 to separate the rotating seat 302 from the surface teeth on the upper wall of the installation groove 301, then rotate the rotating seat 302 according to the angle required to be bent by the feeder, adjust the angle of the axis of the riding card 304 to set it, and tighten the positioning bolt 303 after the angle adjustment is completed, so that the rotating seat 302 is re-positioned by the installation groove 301. Then, fix the chuck seat 1 to the corner of the wall through the expansion bolt, loosen the screws that fix the riding card 304, and then pass the wire ends of the feeder through the corresponding riding card 304 in sequence. Then insert a bending frame 204 from the vertical groove end of the L-shaped groove 201, and the part of the feeder located on the chuck seat 1 passes through the front end of the bending frame 204. Then the staff drives the screw 206 to rotate through a sleeve or a wrench, and the rotating screw 206 pushes the bending frame 204 forward along the two positioning rings 205, thereby driving the feeder to bend along the front end of the bending frame 204. After the bending frame 204 moves to the designated position and the feeder is bent, the screws are tightened, and the riding card 304 will position the feeder on the rotating seat 302. Finally, the staff can rotate the screw 206 in the opposite direction to take it out. The bending frame 204 is limited by the limiting plate 203 under the action of the one-way teeth, keeping the feeder in a tensioned state, and the bending positioning of a feeder is completed. If multiple feeders need to be bent, insert a bending frame 204 into the vertical slot end of the L-shaped slot 201 in turn, and repeat the above operation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
