Description

Technical Field

[0001] This utility model relates to the field of wire feeding frame technology, and in particular to a wire feeding frame that is easy to assemble. Background Technology

[0002] Wires and cables refer to materials used for power, electrical, and related transmission applications. They are typically composed of several or groups of conductors. With the rapid development of the communications industry over the past two decades, these products have also experienced astonishing growth. From simple telephone and telegraph cables of the past, they have evolved into multi-pair cables, coaxial cables, optical cables, data cables, and even composite communication cables. The distribution and prevalence of cables and wires have become more widespread, making cable laying a significant challenge. During cable laying, since cables are mostly coiled on rollers or turntables, the turntable needs to be placed on a cable-laying rack each time a line is laid for easy cable extraction and subsequent arrangement. However, the large size of the cable-laying rack causes inconvenience during transportation, occupying considerable transport space. Furthermore, the large size of the coiled cable rollers requires lifting them into the insertion holes of the insertion pole when placed on the cable-laying rack, a laborious and unsafe process that is relatively cumbersome. Sometimes, equipment is even needed to be erected on the cable-laying rack, resulting in wasted equipment resources.

[0003] Utility model CN221439936U discloses an easily assembled aluminum rod cable feeder, including a base, a support rod, a stabilizing rod assembly, and an upward pushing structure. A heightening block is located in the middle of the upper surface of the base, and a rod slot extending into the base is located in the middle of the heightening block. The upper half of the support rod has an upward pushing structure with a support opening at the push structure location. The upward pushing structure includes a semi-circular ring, a pull rope, and a rope winding reel. One end of the pull rope is tied to the other end of the semi-circular ring, and the other end passes through the support rod along a guide roller and is tied to the rope winding reel. The stabilizing rod assembly includes a crossbar and a lower rotating support rod. U-shaped connectors are located at the lower ends of the crossbar, and one end of the lower rotating support rod is rotatably mounted on the U-shaped connector. This utility model cable feeder is simple to install and disassemble, and easy to transport. Rotating the semi-circular ring upwards causes the rotating shaft to rise and roll into the support opening, thus lifting the cable-winding roller off the ground. Tightening the pull rope interface completes the placement of the roller. The operation is simple and effortless.

[0004] The above-mentioned utility model has many installation steps, is complicated to operate, and has low installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a wire feeding frame that is easy to assemble, so as to solve the problems of numerous installation steps, complex operation, and low installation efficiency mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding frame that is easy to assemble, comprising two mounting bases, each mounting base having a first connecting rod movably inserted into it, each first connecting rod having a second connecting rod sleeved on it, the two second connecting rods having a common crossbar movably connected to them, and the tops of the two second connecting rods having a common top rod rotatably connected to them. Each mounting base has a receiving cavity, and the bottom of each of the two first connecting rods has a connecting shaft installed thereon. The bottom end of the connecting shaft has a frustum installed thereon, which is located inside the receiving cavity. Two limiting blocks are elastically connected to the receiving cavity, and both limiting blocks are located above the frustum.

[0007] Preferably, each of the two second connecting rods has a first connecting hole, and the crossbar is adapted to the first connecting hole.

[0008] Preferably, a connecting block is installed on the top of each of the two second connecting rods, and the two ends of the top rod are rotatably connected to the corresponding connecting block.

[0009] Preferably, each of the two second connecting rods is elastically connected to a limiting shaft, and each of the two first connecting rods is provided with a plurality of limiting holes, which are adapted to the limiting shafts.

[0010] Preferably, each of the two mounting bases has two opposing second connecting holes, and the limiting block is elastically connected in the second connecting holes.

[0011] Preferably, each of the limiting blocks has a sliding shaft installed at the end away from the connecting shaft, and a spring is sleeved on the sliding shaft, with the spring located in the corresponding second connecting hole.

[0012] Preferably, a movable ring is slidably connected to the connecting shaft, and the movable ring is positioned between the frustum and the first connecting rod.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, one of the first connecting rods is inserted into the receiving cavity of the mounting base, thereby inserting the frustum on the first connecting rod into the receiving cavity. Then, two limiting blocks on the mounting base pop out, thereby restricting the frustum within the receiving cavity. Then, the other first connecting rod is movably installed on another mounting base in the same way, thus completing the connection between the first connecting rod and the mounting base. After that, the two mounting bases are adjusted to the appropriate positions so that the top rod is parallel to the ground, thereby allowing the crossbar to be horizontally movably connected to the two second connecting rods. When installing the crossbar, first insert one end of it into the second connecting rod, then attach the cable loop to the crossbar, and finally insert the crossbar into the other second connecting rod, thereby achieving the purpose of successfully assembling the cable feeder and equipping the cable loop on the cable feeder. This method is simple to operate, has a short installation time, and effectively improves the assembly efficiency of the cable feeder. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A wire feeding frame that is easy to assemble includes two mounting bases 1. A first connecting rod 2 is movably inserted into each of the two mounting bases 1. A second connecting rod 3 is sleeved on each of the two first connecting rods 2. The same crossbar 4 is movably connected to the two second connecting rods 3, and the same top rod 5 is rotatably connected to the top of each of the two second connecting rods 3. A receiving cavity 6 is opened on each of the two mounting bases 1. A connecting shaft 7 is installed at the bottom of each of the two first connecting rods 2. A frustum 8 is installed at the bottom end of the connecting shaft 7. The frustum 8 is located inside the receiving cavity 6, and two limiting blocks 9 are elastically connected to the receiving cavity 6. The two limiting blocks 9 are both located above the frustum 8.

[0022] When installing the cable reel, first place two mounting bases 1 on a flat surface. Then, insert one of the first connecting rods 2 into the receiving cavity 6 of the mounting base 1, thereby inserting the frustum 8 on the first connecting rod 2 into the receiving cavity 6. Then, the two limiting blocks 9 on the mounting base 1 pop out, thereby restricting the frustum 8 in the receiving cavity 6. Then, in the same way, movably install the other first connecting rod 2 onto the other mounting base 1, thus completing the connection between the first connecting rod 2 and the mounting base 1. Then, adjust the two mounting bases 1 to the appropriate position so that the top rod 5 is parallel to the ground, thereby allowing the crossbar 4 to be horizontally movably connected to the two second connecting rods 3. When installing the crossbar 4, first insert one end into the second connecting rod 3, then attach the cable loop to the crossbar 4, and finally insert the crossbar 4 into the other second connecting rod 3, thereby achieving the purpose of successfully assembling the cable reel and equipping the cable loop on the cable reel. This method is simple to operate, has a short installation time, and effectively improves the assembly efficiency of the cable reel.

[0023] Specifically, in this embodiment, each of the two second connecting rods 3 is provided with a first connecting hole 10, and the crossbar 4 is adapted to the first connecting hole 10, so that the crossbar 4 can be movably connected to the two second connecting rods 3 through the first connecting hole 10, thereby facilitating the connection of cable loops on the crossbar 4 for subsequent cable laying.

[0024] Specifically, in this embodiment, a connecting block 11 is installed on the top of each of the two second connecting rods 3, and the two ends of the top rod 5 are rotatably connected to the corresponding connecting block 11. This allows the top rod 5 to be rotatably connected to the second connecting rod 3 through the connecting block 11, which makes it easier to fold the top rod 5 and the two second connecting rods 3 together by rotating the top rod 5 when disassembling the wire feeding frame, thereby reducing the space occupied.

[0025] Specifically, in this embodiment, each of the two second connecting rods 3 is elastically connected to a limiting shaft 12, and each of the two first connecting rods 2 is provided with a plurality of limiting holes 13. The limiting holes 13 are adapted to the limiting shafts 12, so that the height of the second connecting rod 3 on the first connecting rod 2 can be adjusted through the adaptability of the limiting holes 13 and the limiting shafts 12. This allows the cable feeder to be adapted to cable coils of different specifications, further improving the practicality of the cable feeder.

[0026] Specifically, in this embodiment, each of the two mounting bases 1 has two opposing second connecting holes 14. The limiting block 9 is elastically connected in the second connecting hole 14, so that when the frustum 8 enters the receiving cavity 6, the limiting block 9 will be pushed into the corresponding second connecting hole 14 by the thrust applied by the frustum 8, thereby facilitating the frustum 8 to enter the receiving cavity 6.

[0027] Specifically, in this embodiment, a sliding shaft 15 is installed on the end of each of the limiting blocks 9 away from the connecting shaft 7. A spring 16 is sleeved on the sliding shaft 15. The spring 16 is located in the corresponding second connecting hole 14, so that after the frustum 8 enters the receiving cavity 6, the spring 16 will push the limiting block 9 to move towards the frustum 8 under the action of elastic force, thereby restricting the frustum 8 in the receiving cavity 6 and locking the two together.

[0028] Specifically, in this embodiment, a movable ring 17 is slidably connected to the connecting shaft 7. The movable ring 17 is located between the frustum 8 and the first connecting rod 2, so that when the wire feeding frame needs to be dismantled, the worker can move the first connecting rod 2 downward, move the movable ring 17 to below the limiting block 9, and then move the first connecting rod 2 upward, thereby pulling the first connecting rod 2 out of the mounting base 1, thereby terminating the connection between the two and facilitating the quick dismantling of the wire feeding frame.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
