Description

Technical Field

[0001] This utility model relates to the field of cable rack technology, specifically a cable rack with an adjustable spacing structure. Background Technology

[0002] Cable storage racks are specialized storage equipment used for the centralized storage of cable products. The racks are mostly made of high-strength steel to ensure stable load-bearing capacity, and the surface is treated with rust prevention to adapt to humid or dusty warehouse environments. In practical applications, cable storage racks are widely used in warehouses of industries such as power, communications, and construction. By standardizing storage processes, they reduce problems such as cable tangling and damage, and improve inbound and outbound efficiency. They are an indispensable infrastructure in modern cable storage management.

[0003] According to the search, Chinese patent document, publication number: CN220975423U, discloses a cable storage rack, which belongs to the field of storage rack technology. The surface of the support plate is threadedly connected to the surface of the square rack with threaded posts. A water tank is fixedly installed on the side of the base. A fixing plate is fixedly connected to the side of the base. A support post is fixedly connected to the top of the fixing plate. A light is fixedly installed on the top of the support post. The threaded posts are designed to facilitate disassembly.

[0004] The aforementioned device requires disassembling and assembling threaded posts each time the shelf height spacing is adjusted. This structure makes it impossible to perform continuous operation during the adjustment process. If the warehouse needs to adjust the shelf height spacing of all shelves simultaneously according to the specifications of the goods entering the warehouse, a lot of time will be spent on disassembling and assembling threaded posts, extending the preparation cycle before the goods are put on the shelves. In view of this, we provide a cable rack with a spacing adjustment structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cable rack with an adjustable spacing structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable rack with an adjustable spacing structure, comprising a welding frame, wherein multiple sliding rods are fixedly connected to both sides of the inner wall of the welding frame, and a bottom shelf is fixedly connected to the bottom of the welding frame, a top shelf is slidably connected to the top of the welding frame via sliding rods, and multiple middle shelves are slidably connected to the center of the welding frame via sliding rods. Multiple slide rails are fixedly connected to both sides of the bottom shelf, top shelf, and middle shelf, one end of each slide rail is fixedly connected to a connector via bolts, and a moving part is slidably connected to the outer wall of the slide rail away from the connector. A connecting shaft is fixedly connected to one side of the outer wall of both the connector and the moving part, and a synchronous connecting rod is rotatably connected to one end of the connecting shaft.

[0007] As mentioned above, the top surfaces of the bottom, top, and middle cargo pallets are all equipped with restraint fences, and the restraint fences have a semi-circular open structure.

[0008] As described above, a drive motor is fixedly connected to the center of the top surface of the welding frame, and a screw is fixedly connected to the output end of the drive motor. The top of the outer wall of the screw is threadedly connected to the center of the inner surface of the top layer of the cargo plate.

[0009] As mentioned above, the outer wall of the screw is provided with multiple telescopic tubes, and the multiple telescopic tubes are respectively installed between the welding frame, the bottom cargo plate, the top cargo plate and the middle cargo plate.

[0010] As described above, the multiple synchronous connecting rods are arranged in a cross pattern, and the two ends of the synchronous connecting rods are rotatably connected to the outer walls of multiple connecting shafts through rotating shafts.

[0011] The aforementioned synchronous connecting rods are symmetrically arranged on both sides inside the welding frame.

[0012] Compared with existing technologies, this cable rack with an adjustable spacing structure has the following advantages:

[0013] I. This utility model forms a rhomboid structure by arranging multiple synchronous connecting rods in a cross pattern. The synchronous connecting rods are connected to the connecting parts and moving parts on both sides of the bottom, top, and middle cargo plates through connecting shafts. When the drive motor drives the top cargo plate to move vertically through the screw, the synchronous connecting rods can drive the bottom, top, and middle cargo plates to move up and down synchronously through the connecting shafts. This eliminates the need for disassembling and assembling the threaded column in the traditional structure. At the same time, the cross coordination of multiple synchronous connecting rods ensures that the spacing between the bottom, top, and middle cargo plates remains uniform, reducing the preparation period before goods are put on the shelves and solving the problem of operation interruption caused by frequent disassembly and assembly of threaded columns.

[0014] Second, this utility model uses sliding rods to constrain the top and middle layer cargo plates, providing stable conditions for subsequent spacing adjustment operations and further improving the vertical movement stability of the bottom, top, and middle layer cargo plates.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[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] like Figures 1-5 As shown, this utility model provides a technical solution: a cable rack with an adjustable spacing structure, including a welding frame 1. Multiple sliding rods 101 are fixedly connected to both sides of the inner wall of the welding frame 1. A bottom shelf 2 is fixedly connected to the bottom of the welding frame 1. A top shelf 201 is slidably connected to the top of the welding frame 1 through the sliding rods 101. Multiple middle shelf 202 is slidably connected to the center of the welding frame 1 through the sliding rods 101. Multiple slide rails 203 are fixedly connected to both sides of the bottom shelf 2, the top shelf 201, and the middle shelf 202. A connector 204 is fixedly connected to one end of the slide rail 203 by bolts. A moving part 205 is slidably connected to the outer wall of the slide rail 203 away from the connector 204. A connecting shaft 206 is fixedly connected to one side of the outer wall of the connector 204 and the moving part 205. A synchronous connecting rod 207 is rotatably connected to one end of the connecting shaft 206.

[0024] Under the action of the slide bar 101, the bottom layer 2, the top layer 201 and the middle layer 202 can all be vertically displaced along the inner wall of the welding frame 1, and cooperate with multiple synchronous connecting rods 207 and connecting shafts 206. By simply starting the drive motor 102 to drive the screw 103 to rotate, the layer height spacing between the bottom layer 2, the top layer 201 and the middle layer 202 can be changed synchronously.

[0025] like Figures 1-3 As shown, the top surfaces of the bottom cargo plate 2, the top cargo plate 201, and the middle cargo plate 202 are all equipped with restraint fences 208, and the restraint fences 208 have a semi-circular open structure.

[0026] The restraint fence 208 has a semi-circular open structure. During the adjustment of the height spacing of the cargo pallet, it can restrain the cable roll, effectively restrain the cable, prevent it from slipping, and at the same time, it does not hinder the loading and unloading of the cable.

[0027] like Figure 1 and Figure 3 As shown, a drive motor 102 is fixedly connected to the center of the top surface of the welding frame 1, and a screw 103 is fixedly connected to the output end of the drive motor 102. The top of the outer wall of the screw 103 is threadedly connected to the center of the inner surface of the top layer cargo plate 201.

[0028] The drive motor 102 drives the top cargo plate 201 to rise and fall via the screw 103, thereby completing the electric adjustment of the height of the top cargo plate 201.

[0029] like Figure 3 As shown, the outer wall of the screw 103 is provided with multiple telescopic tubes 104. The telescopic tubes 104 are sleeve-type structures that expand and contract with the change of the spacing between the cargo plates to protect the screw 103. The multiple telescopic tubes 104 are respectively installed between the welding frame 1, the bottom cargo plate 2, the top cargo plate 201 and the middle cargo plate 202.

[0030] The telescopic tube 104 is installed between the welding frame 1, the bottom cargo plate 2, the top cargo plate 201 and the middle cargo plate 202 to protect the screw 103 and block external dust and moisture, so as to prevent dust from entering the connection of the screw 103 and causing jamming.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, multiple synchronous connecting rods 207 are arranged in a cross pattern, and the two ends of the synchronous connecting rods 207 are rotatably connected to the outer walls of multiple connecting shafts 206 through rotating shafts.

[0032] Multiple synchronous linkages 207 are arranged in a cross pattern, so that the spacing between the bottom cargo plate 2, the top cargo plate 201, and the middle cargo plate 202 can change synchronously when the layer height spacing is adjusted.

[0033] like Figures 1-3 As shown, multiple synchronous connecting rods 207 are symmetrically arranged on both sides inside the welding frame 1.

[0034] Multiple synchronous connecting rods 207 are symmetrically arranged on both sides inside the welding frame 1 to avoid unilateral displacement as much as possible during the adjustment process and improve the overall structural stability.

[0035] It should be noted that the threads on the outer wall of the screw 103 only exist at the connection between the top and the top layer cargo plate 201. The bottom outer wall of the screw 103 is smooth and will not interfere with the middle layer cargo plate 202 when it rotates.

[0036] Working principle: When the original spacing between the pallets cannot accommodate the existing cable rolls, the drive motor 102 on the top surface of the welding frame 1 is activated, and its output end drives the screw 103 to rotate. The screw 103 drives the top pallet 201 to move upward along the slide rails 101 on both sides. As the top pallet 201 moves, the connecting parts 204 and connecting shafts 206 on the slide rails 203 on both sides, and the moving parts 205 slide along the slide rails 203. They are connected to the synchronous connecting rod 207 through the connecting shaft 206. The middle pallet 202 is connected to the synchronous connecting rod 207 through the connecting shaft 206. Then, the top layer pallet 201 moves synchronously as it rises and falls, and the cross-placed synchronous connecting rods 207 rotate accordingly, pulling the bottom middle layer pallet 202 upwards synchronously. The middle layer pallet 202 rises synchronously under the constraint of the sliding rod 101. When the height spacing between the bottom layer pallet 2, the top layer pallet 201 and the middle layer pallet 202 meets the existing cable roll storage height, the drive motor 102 can be turned off, the screw 103 self-locks and fixes the position of the top layer pallet 201 and the middle layer pallet 202, and at the same time the constraint fence 208 effectively constrains the cable to prevent it from slipping.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
