Description

Technical Field

[0001] This utility model relates to the field of mechanical repair auxiliary equipment technology, and in particular to a portable folding mechanical repair tool rack. Background Technology

[0002] In the daily maintenance and emergency repair of mechanical equipment, maintenance personnel need to carry a large number of professional tools, such as wrenches, screwdrivers, pliers, and various measuring instruments. For easy carrying and management, these tools are stored in portable toolboxes or tool bags. However, with the increasing precision of mechanical equipment, the types and quantities of tools required are increasing day by day. Traditional single-layer or simple multi-layer toolboxes are gradually showing their limitations in actual use, especially in narrow or complex maintenance sites. Maintenance personnel not only need to quickly find the required tools, but also need an operating platform that can stably hold the tools and is at a suitable height.

[0003] Most existing portable toolboxes adopt a simple flip-top or tray-style structure. This structure occupies a large amount of floor space when unfolded, and tools are stacked on top of each other, with lower tools being obscured by upper ones. This forces maintenance personnel to frequently search for tools, seriously affecting maintenance efficiency. In addition, existing toolboxes are placed directly on the ground without effective height adjustment or support structures. This forces maintenance personnel to frequently bend over or squat to retrieve tools, which can easily cause physical fatigue over long periods of time. Furthermore, in damp or oily environments, the bottom of the toolbox is easily damaged or contaminated. Although there are some tool stands with support legs on the market, these devices are bulky and heavy, failing to meet the needs of portability and rapid transfer, and making it difficult to balance the three aspects of large-capacity storage, convenient access, and stable support.

[0004] Therefore, this utility model proposes a portable folding mechanical repair tool rack to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the portable folding mechanical repair tool rack, such as unreasonable internal space layout leading to cumbersome tool retrieval and lack of stable and flexible support structure at the bottom resulting in unsuitable height for maintenance work, this utility model aims to provide a portable folding mechanical repair tool rack with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a portable folding mechanical repair tool rack, including: a portable frame and a base frame fixedly connected to the bottom of the inner side of the portable frame, as well as a folding mechanism disposed inside the portable frame and a support mechanism disposed at the bottom of the portable frame.

[0007] The folding mechanism includes a limiting rod, a traction rod, a moving frame, and a tray, while the support mechanism includes a fixed frame, a first support leg, a second support leg, a folding plate, and a connecting shaft.

[0008] Furthermore, the top inner left and right sides of the base frame are rotatably connected to limit rods, and the top outer left and right sides of the base frame are rotatably connected to traction rods. The middle of the movable frame is rotatably connected to the middle of the traction rod and the middle of the limit rod. The top of the traction rod is rotatably connected to a tray. Through this multi-link cooperation, the tool rack can be unfolded in layers. The fixed frame is fixedly connected to the front and rear sides of the bottom of the portable frame. The inner left and right sides of the fixed frame are respectively rotatably connected to support leg one and support leg two. The inner adjacent sides of support leg one and support leg two are rotatably connected to a folding plate and a connecting shaft. The connecting shaft passes through the bottom of the folding plate. One end of the folding plate is rotatably connected to the side wall of support leg one, and the connecting shaft is rotatably connected to the side wall of support leg two, thus constructing a stable off-ground support structure.

[0009] Preferably, handles are fixedly connected to the top left and right sides of the tray. When the traction rod is subjected to force, it drives the moving frame and the tray to make parallelogram movements relative to the base frame, thereby unfolding or folding. The handles make it easy for the user to apply operating force.

[0010] Preferably, the internal fixed connection of the traction rod has multiple fixing clips, which are constructed as U-shaped or C-shaped buckle structures that can hold and fix mechanical repair tools to prevent the tools from falling off during movement.

[0011] Preferably, a pull-out shelf is slidably connected to the inside right side of the base frame, and slide bars are fixedly connected to the front and rear sides of the pull-out shelf. The slide bars and the inner wall of the base frame form a linear guide engagement, thereby increasing the additional storage space.

[0012] Preferably, the pull-out shelf unfolds laterally along the length of the base frame via a slide bar, and when stored, the pull-out shelf is located below the movable frame. This layout makes full use of the deep space inside the base frame.

[0013] Preferably, support leg one is folded and stored inside support leg two. The outer width of support leg one is smaller than the inner width of support leg two, and support leg one and support leg two are folded in opposite directions. This nested design effectively reduces the volume after folding.

[0014] Preferably, the folding plate and connecting shaft form a lateral rigid support when the support mechanism is unfolded, thereby locking the relative positions of support leg one and support leg two and ensuring the stability of the entire tool rack under load.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problems of low internal space utilization and mutual obstruction of tools when using existing portable toolboxes by setting a folding mechanism consisting of a base frame, traction rod, limiting rod, moving frame and tray inside the portable frame. It utilizes the principle of parallel linkage to realize the stepped layering unfolding and linkage storage of the tool rack. It achieves the effect of significantly improving the tool storage capacity and on-site access convenience while ensuring compactness.

[0016] 2. This utility model solves the problem that existing toolboxes placed directly on the ground cause maintenance personnel to frequently bend over and are unstable on complex ground by setting a support mechanism at the bottom of the portable rack, which includes a fixed frame, nestable and foldable support legs one and two, and a folding plate locking structure. It achieves the effect of being able to quickly raise the height of the tool rack according to the working environment, providing stable off-ground support, and meeting ergonomic requirements.

[0017] 3. This utility model solves the problems of difficult utilization of deep space in traditional tool racks and easy scattering of scattered tools during movement by setting a lateral sliding pull-out frame inside the base frame and setting a fixing clip inside the traction rod. It achieves the effect of further expanding the effective storage area and ensuring that all kinds of maintenance tools remain neat, orderly and securely fixed during transportation and deployment.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0021] Please refer to Figures 1 to 6 This utility model provides a portable folding mechanical repair tool rack, which aims to solve the problems of inconvenient tool layering and unfolding due to the simple structure of existing mechanical repair tool racks, and the lack of a stable lifting structure at the bottom, resulting in an unsuitable height for maintenance operations.

[0022] Please refer to Figure 2 , Figure 3 and Figure 4 A portable folding mechanical repair tool rack includes a portable frame 1 and a base frame 205 fixedly connected to the bottom inner side of the portable frame 1. The portable frame 1 serves as the basic support box for the entire tool rack, while the base frame 205 serves as a basic platform for storing tools inside the portable frame 1 and provides an installation base for the subsequent unfolding structure.

[0023] Please refer to Figure 4 and Figure 5 The folding mechanism 2 includes a limiting rod 204, a traction rod 202, a moving frame 203, and a tray 4. The limiting rod 204 is rotatably connected to the left and right sides of the top inner side of the base frame 205. The traction rod 202 is rotatably connected to the left and right sides of the top outer side of the base frame 205. The middle part of the moving frame 203 is rotatably connected to the middle part of the traction rod 202 and the middle part of the limiting rod 204. This parallel linkage structure ensures that when the traction rod 202 is rotated under force, it can drive the moving frame 203 to maintain a horizontal posture and perform a parallelogram movement relative to the base frame 205, thereby realizing a stepped unfolding or folding. The tray 4 is rotatably connected to the top of the traction rod 202. The function of the tray 4 is to serve as the uppermost tool storage platform, and its position is lifted and moved forward through the linkage of the traction rod 202.

[0024] Please refer to Figure 3 and Figure 6The support mechanism 3 has a fixed frame 301, a first support leg 302, a second support leg 305, a folding plate 303, and a connecting shaft 304. The fixed frame 301 is fixedly connected to the front and rear sides of the bottom of the portable frame 1. The first support leg 302 is rotatably connected to the left side of the inner wall of the fixed frame 301, and the second support leg 305 is rotatably connected to the right side of the inner wall of the fixed frame 301. The first support leg 302 and the second support leg 305 can be folded downward relative to the fixed frame 301 to support the ground, or folded upward to be stored inside the fixed frame 301. One end of the folding plate 303 is rotatably connected to the inner side wall of the first support leg 302. The connecting shaft 304 passes through the bottom of the folding plate 303 and is rotatably connected to the inner side wall of the second support leg 305. When the support mechanism 3 is unfolded, the folding plate 303 and the connecting shaft 304 cooperate to form a lateral rigid support, thereby locking the relative position of the first support leg 302 and the second support leg 305 and preventing the frame from tipping over.

[0025] As a preferred embodiment, to improve the ease of operation of a portable folding mechanical repair tool rack, please refer to... Figure 1 , Figure 2 and Figure 5 The top left and right sides of the tray 4 are fixedly connected to handles 201. The handles 201 are used for users to hold and apply force to pull the traction rod 202 to unfold and store the folding mechanism 2.

[0026] As another preferred embodiment, to improve the fixing stability of mechanical repair tools of a specific shape, please refer to... Figure 5 The pull rod 202 has multiple fixing clips 206 fixedly connected inside. The fixing clips 206 are constructed as U-shaped or C-shaped buckle structures that can hold and fix mechanical repair tools. The fixing clips 206 use their own elastic deformation to firmly lock screwdrivers, wrenches and other tools into the inner space of the pull rod 202 to prevent the tools from falling out during movement.

[0027] As another preferred implementation, to further expand the storage space of the tool rack and improve space utilization, please refer to... Figure 5 A pull-out bracket 207 is slidably connected to the inside right side of the base frame 205. Slide strips 208 are fixedly connected to the front and rear sides of the pull-out bracket 207. A linear guide fit is formed between the slide strips 208 and the inner wall of the base frame 205. The pull-out bracket 207 unfolds laterally along the length of the base frame 205 through the slide strips 208. When the pull-out bracket 207 is stored, it is located below the movable frame 203. This lateral pull-out structure allows the deep space inside the base frame 205 to be effectively utilized.

[0028] As another preferred embodiment, to achieve a compact and flat structure after the support mechanism 3 is stowed, please refer to... Figure 3 and Figure 6The outer width of support leg 1 302 is smaller than the inner width of support leg 2 305, and support leg 1 302 is designed to be folded and stored inside support leg 2 305. Support leg 1 302 and support leg 2 305 fold in opposite directions. This nested folding design eliminates the spatial interference between the two sets of support legs when stored, making the bottom of the portable stand 1 flatter.

[0029] Working principle: When a portable folding mechanical repair tool rack is needed for repair work, the user first flips the support mechanism 3 at the bottom of the portable rack 1, and folds the support leg 1 302 and support leg 2 305 outward until the support leg 1 302 and support leg 2 305 contact the ground. At this time, the folding plate 303 and the connecting shaft 304 are straightened and form a lateral support, locking the angle of the support leg 1 302 and support leg 2 305, thereby steadily raising the height of the portable rack 1; Next, the user holds the handle 201 on the tray 4 and pulls it to the sides and upwards. The traction rod 202 rotates around the base frame 205 under the action of the pulling force. Since the traction rod 202, the limiting rod 204, the base frame 205 and the moving frame 203 form a parallelogram linkage mechanism, the moving frame 203 and the tray 4 will maintain a horizontal posture and move upwards and outwards, unfolding in a stepped shape. At this time, the tools in the base frame 205, the moving frame 203 and the tray 4 are fully exposed in the user's field of vision, making them easy to access. If more space is needed, the user can pull the pull-out frame 207 to the right. The slide bar 208 slides in the base frame 205, unfolding the pull-out frame 207 to the side. When the maintenance is finished and storage is required, the user reverses the operation of the handle 201 to push the folding mechanism 2 back into the portable frame 1, and folds the first support leg 302 into the inside of the second support leg 305. Finally, the second support leg 305 is folded into the fixed frame 301.
