Power maintenance racks are specialized tools used for the maintenance and repair of power equipment, and they are especially important in the operation and maintenance of high-voltage power equipment. During the power maintenance process, it is necessary to fix and repair broken or damaged high-voltage power lines, so a cable support frame is used to position the cables.

[0003] However, existing power maintenance racks have the following drawbacks. When inspecting cables, a power maintenance rack is needed to support the cables and facilitate the inspection by the staff. However, most power maintenance racks are just ordinary supports, which are not convenient to adjust the length of the supports according to the inspection needs, and are not convenient to store and carry. Therefore, the current power maintenance racks need to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a power maintenance rack that is easy to fold and store, in order to solve the problem mentioned in the background art that most power maintenance racks on the market are just ordinary brackets, which are not convenient to adjust the length of the bracket according to maintenance needs and are not convenient to store and carry.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power maintenance rack that is easy to fold and store, comprising a support plate and a storage tube. A fixing plate is fixed to one side of the support plate, and the storage tube is fixed to the side of the support plate near the fixing plate. A folding mechanism is connected to the side of the fixing plate away from the support plate. A second slider is connected to the end of the folding mechanism away from the fixing plate. A sliding rod slides through the interior of the second slider. A rotating shaft and a fixing block are provided on the inner side of the folding mechanism. The folding mechanism includes a first connecting rod, a second connecting rod, a knob, a first slider, and a screw. The screw is installed in the reserved groove of the fixing plate through a bearing.

[0006] Preferably, a first slider is threaded onto the outer side of the screw, a knob is connected to one end of the screw and the knob is located on the outside of the storage cylinder, and a second connecting rod is connected to one side of the first slider via a movable shaft.

[0007] Preferably, the two ends of the second connecting rod are connected to the first connecting rod via a movable shaft, and the middle parts of the first connecting rod and the second connecting rod are connected via a rotating shaft.

[0008] Preferably, the end of the second connecting rod away from the first slider is connected to the fixed block via a movable shaft, the first connecting rod is connected to the second slider via a movable shaft, and the end of the first connecting rod away from the second slider is connected to the fixed block via a movable shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Equipped with a folding mechanism and a storage cylinder, rotating the knob drives the screw to rotate, and the screw engages with the first slider. The first slider then moves outside the screw, causing it to drive the second connecting rod to rotate. The second connecting rod then pulls the first connecting rod to rotate through the movable shaft and the rotating shaft. At the same time, the first connecting rod drives the second slider to slide outside the sliding rod, allowing the first and second connecting rods to push the extension plate to one side. This causes the extension plate to extend the sleeve out of the storage cylinder, facilitating the clamping and limiting of cables. The extension plate can be adjusted in length using the folding mechanism, and the sleeve can also be folded and stored in the storage cylinder. Workers can carry the power maintenance frame by the handle, improving the practicality of the power maintenance frame.

[0015] 2. A limiting mechanism is set up. The limiting frame is placed on both sides of the cable rack or utility pole. Then, the handle is rotated to drive the double-acting screw to rotate. The double-acting screw and the limiting frame are then threaded together, so that the limiting frame moves closer to each other on the outside of the double-acting screw. The limiting frame is clamped on both sides of the cable rack or utility pole, which facilitates the quick and easy installation of the power maintenance frame on the cable rack or utility pole, improving the convenience of the power maintenance frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a power maintenance rack that is easy to fold and store, including a support plate 1 and a storage tube 8. A fixing plate 2 is fixed to one side of the support plate 1, and the storage tube 8 is fixed to the side of the support plate 1 near the fixing plate 2. A folding mechanism 9 is connected to the side of the fixing plate 2 away from the support plate 1. An extension plate 3 is provided on the outer side of the second slider 11. A sleeve 4 is movably connected to the side of the fixing plate 2 away from the folding mechanism 9 through a rotating seat 7. A fastening bolt 5 passes through the inner thread of the sleeve 4.

[0024] Please see Figures 1-5The folding mechanism 9 has a second slider 11 connected to one end away from the fixed plate 2. A sliding rod 14 slides through the interior of the second slider 11. The inner side of the folding mechanism 9 has a rotating shaft 10 and a fixing block 15. The folding mechanism 9 includes a first connecting rod 901, a second connecting rod 902, a knob 903, a first slider 904, and a screw 905. The screw 905 is installed in the pre-reserved slot of the fixed plate 2 via a bearing. The outer side of the screw 905 is threaded onto the first slider 904. One end of the screw 905 is connected to the knob 903, which is located outside the storage cylinder 8. One side of the first slider 904 is connected to the second connecting rod 902 via a movable shaft. The second connecting rod 902... A first connecting rod 901 is connected to both ends via a movable shaft. The middle parts of the first connecting rod 901 and the second connecting rod 902 are connected via a rotating shaft 10. The end of the second connecting rod 902 away from the first slider 904 is connected to the fixed block 15 via a movable shaft. The first connecting rod 901 is connected to the second slider 11 via a movable shaft. The end of the first connecting rod 901 away from the second slider 11 is connected to the fixed block 15 via a movable shaft. A groove 13 is provided inside the extension plate 3 near the second slider 11. The second slider 11 and the groove 13 are slidably connected. The fixed block 15 is fixedly connected to both the extension plate 3 and the fixed plate 2. The first connecting rod 901 and the second connecting rod 902 are distributed in a crisscross pattern.

[0025] In practice, when inspecting cables, a power maintenance frame is needed to support them for easier maintenance. However, most power maintenance frames are just ordinary supports, which are not convenient for adjusting the length according to maintenance needs and are inconvenient for storage and transport. To address this, knob 903 can be rotated to rotate screw 905. Screw 905 engages with slider 904, causing slider 904 to move outside screw 905, thus rotating connecting rod 902. Link 902 then pulls link 901 to rotate via movable shaft and rotating shaft 10. At the same time, link 901 drives slider 11 to slide outside of slider 14. This allows link 901 and link 902 to push extension plate 3 to one side, causing extension plate 3 to extend sleeve 4 out of storage tube 8 for easy clamping and limiting of cables. Extension plate 3 can adjust the length of support through folding mechanism 9, and sleeve 4 can also be folded and stored in storage tube 8. Workers can carry the power maintenance frame through handle 12, improving the practicality of the power maintenance frame.

[0026] Please see Figure 2 , Figure 4 and Figure 5A limiting mechanism 6 is installed on the inner side of the support plate 1. A handle 12 is connected to one side of the storage tube 8. The limiting mechanism 6 includes a handle 601, a bidirectional lead screw 602, and a limiting frame 603. The bidirectional lead screw 602 is installed in the built-in groove of the support plate 1 through a bearing. One end of the bidirectional lead screw 602 is connected to the handle 601. The outer side of the bidirectional lead screw 602 is threaded with the limiting frame 603. A triangular slot is provided on the inner side of the limiting frame 603.

[0027] In practice, since most power maintenance racks are bolted to cable racks or utility poles, which is time-consuming, the limiting frame 603 can be placed on both sides of the cable rack or utility pole. Then, the handle 601 is rotated, causing the handle 601 to drive the double-acting screw 602 to rotate. Subsequently, the double-acting screw 602 and the limiting frame 603 are threadedly connected, so that the limiting frame 603 is close to each other on the outside of the double-acting screw 602. The limiting frame 603 is clamped on both sides of the cable rack or utility pole, which facilitates the quick installation of the power maintenance rack on the cable rack or utility pole, improving the convenience of the power maintenance rack.

[0028] Working principle: When using this convenient foldable power maintenance rack, the support plate 1 is first installed on the cable rack or utility pole by the limiting mechanism 6. Then, the extension plate 3 and the sleeve 4 are extended out of the storage tube 8 by the folding mechanism 9. Subsequently, the sleeve 4 is rotated by the rotating seat 7 to place the cable inside the sleeve 4. The sleeve 4 is then rotated again by the rotating seat 7. Finally, the fastening bolt 5 is installed on the sleeve 4 so that the sleeve 4 fits over the outside of the cable, which facilitates the support of the cable and improves the convenience and practicality of the power maintenance rack. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
