Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a cable head installation device for an inflatable cabinet. Background Art

[0002] With the development of the power industry, inflatable cabinets are increasingly being used. Reliable cable installation is essential. Typically, on-site installers manually push plug-in cable heads into place. This is limited by the confines of the cable room, making it difficult to apply force, time-consuming, and labor-intensive. This can lead to improper installation of the cable heads. Some installation tools use custom tools, which can cause uneven force and offset, increasing contact resistance and leading to abnormal temperature rise, potentially causing safety incidents. Therefore, a reliable, labor-saving installation device is required to meet actual installation requirements. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a cable head installation device for an inflatable cabinet. Through a more integrated structural design, it solves the problems of uneven force and offset during cable head installation and the inconvenient installation problem of the narrow cable room space in the prior art.

[0004] In order to achieve the purpose of this utility model, the technical solution adopted is:

[0005] A cable head installation device for an inflatable cabinet, comprising:

[0006] a mounting rod, wherein the end portion of the mounting rod is connected to a mounting base plate, and a first connecting plate and a second connecting plate are symmetrically provided on the mounting base plate;

[0007] A first supporting wheel is provided on the first connecting plate, and a first four-sided step structure is provided on the outer periphery of the first supporting wheel;

[0008] A second supporting wheel is provided on the second connecting plate, and a second four-sided step structure is provided on the outer periphery of the second supporting wheel;

[0009] A connecting rod structure is provided on the lower side of the first connecting plate and the second connecting plate, and a first suspension hinge structure and a second suspension hinge structure are provided on both sides of the connecting rod structure respectively.

[0010] In a preferred embodiment of the present invention, a mounting hole is opened in the middle of the mounting base plate, and a connecting shaft passes through the mounting hole to connect the mounting base plate to the mounting rod.

[0011] In a preferred embodiment of the present invention, the first suspension hinge structure and the second suspension hinge structure are fixed on the top of the cable chamber.

[0012] The beneficial effects of the present invention are:

[0013] Unlike previous installation methods that relied solely on manual labor, this greatly reduces labor intensity. Unlike other installation tools, the innovative design of four-sided stepped wheels prevents noticeable displacement when subjected to force during use, providing better support compared to simple circular wheels. This utility model has a simple structure and is easy to carry. The cable head can be easily installed using the lever principle. The threaded end of the connecting rod in this device allows for different cabinet installation distances by extending the connecting rod to increase the lever arm for more labor-saving operation, making it highly practical.

[0018] like Figure 1 The cable head installation device of the inflatable cabinet shown includes a mounting rod 40 for installing other components. The end of the mounting rod 40 is connected to a mounting base plate 50, and a symmetrical first connecting plate 11 and a second connecting plate 12 are provided on the mounting base plate 50.

[0019] A first supporting wheel 21 is provided on the first connecting plate 11 , and a first four-sided step structure 211 is provided on the outer periphery of the first supporting wheel 21 .

[0020] A second supporting wheel 22 is provided on the second connecting plate 12 , and a second four-sided step structure 222 is provided on the outer periphery of the second supporting wheel 22 .

[0021] A connecting rod structure 60 is provided on the lower side of the first connecting plate 11 and the second connecting plate 12 , and a first suspension hinge structure 31 and a second suspension hinge structure 32 are provided on both sides of the connecting rod structure 60 , respectively.

[0022] The first suspension hinge structure 31 and the second suspension hinge structure 32 are fixed on the top of the cable chamber.

[0023] A mounting hole is defined in the middle of the mounting base plate 50 , and the connecting shaft 70 passes through the mounting hole 50 to connect the mounting base plate 50 to the mounting rod 40 .

[0024] The first and second connecting plates 11, 12 of the device are adjusted to accommodate different cable head types. The first and second supporting wheels 21, 22 of the device utilize a four-sided stepped structure, which effectively prevents uneven force on the cable head during installation. The first and second hanging hinge structures 31, 32 can be connected to the cabinet body as fixed fulcrums.

[0025] Compared to conventional assembly methods that rely solely on assemblers and use conventional cylindrical rollers as fulcrums, there are problems with uneven force on the cable head during installation, which can lead to deviation. Furthermore, the labor intensity is high and it is difficult to ensure that the cable head is properly installed. The present invention can solve the problem of inconvenient and limited space during on-site installation by connecting the mounting rod 40, and effectively solve the problem of uneven force on the cable head during installation.

[0026] Because of the above structure, the working principle of the utility model is:

[0027] 1) During on-site installation, pre-insert the cable head into the insulating sleeve;

[0028] 2) Fix the two suspension hinges 30 of the present invention to the top of the cable chamber;

[0029] 3) Place the two step surfaces of the support wheel 20 of the present invention close to the bottom surface of the flange 80 ( Figure 2 );

[0030] 4) Hang the suspension hinge 30 on the connecting rod 60 and use the lever principle to press down the device to push the flange 80 upward;

[0031] 5) Adjust the positions of the suspension hinge 30 and the connecting rod 30 until the cable head is installed.

[0032] Through the above-mentioned implementation mode, the flange 80 is pushed up using the lever principle, and the bottom surface of the flange 80 fits with the stepped surfaces of the first support wheel 21 and the second support wheel 22, which can ensure that the cable head is evenly stressed when pressed down and will not deviate, thereby ensuring installation reliability. The use of this utility model reduces labor intensity and improves assembly efficiency.

[0033] The basic principles and main features of the utility model and the advantages of the utility model are shown and described above.
