Description

Technical Field

[0001] This utility model relates to a ladder with a rotatable and closable tool tray. Background Technology

[0002] With the increasing demand for home maintenance, engineering construction and routine repair work, ladders, as a commonly used auxiliary tool for working at heights, are widely used in homes, factories and construction fields.

[0003] To facilitate the temporary placement of tools, spare parts, and other items while using ladders, various ladders with tool trays have appeared on the market. Tool trays effectively improve work efficiency and avoid the need for frequent climbing up and down the ladder to retrieve tools, thus possessing high practical value.

[0004] Currently, ladders with tool trays on the market mainly include two structural forms: The first type is the ladder with a fixed tool tray. In this type of structure, the tool tray is usually fixedly connected to the ladder frame and is pre-installed at the factory. Although this type of structure is convenient to use, it has the problems of large packaging volume, high transportation costs, and large storage space for users. Moreover, in order to control the overall size, the size of the tool tray is often limited, and the capacity is relatively small, which may not meet the needs of users to place multiple tools or large objects in some cases.

[0005] The second type is the ladder with a detachable tool tray. In this type of structure, the tool tray can be installed or disassembled by the user as needed to reduce its size during storage and transportation. However, this type of structure has certain drawbacks in actual use: the user needs to install it before each use, and disassemble it after use to save space. Frequent disassembly and assembly can easily lead to wear and tear on the connecting parts or damage to the tool tray. There is also a risk of losing parts, which affects the user experience and product lifespan. Utility Model Content

[0006] The purpose of this utility model is to provide a ladder with an adjustable tool tray that can effectively reduce packaging volume, facilitate storage, and avoid the cumbersome disassembly and assembly.

[0007] The purpose of this utility model is achieved as follows: A tool tray rotatable ladder includes a front ladder frame, a rear ladder frame, a connecting lug, and a tool tray. The front ladder frame and the rear ladder frame are connected by the connecting lug, so that the front ladder frame and the rear ladder frame can be unfolded or folded together. The top of the left ladder tube and the top of the right ladder tube of the front ladder frame form a tool tray mounting area. The top of the left ladder tube and the top of the right ladder tube of the front ladder frame are both provided with connecting ears, and the connecting ears are provided with an unfolding limit part and a retracting limit part at the corresponding tool tray installation area. The left and right sides of the tool disk are provided with blocking parts. The tool disk is rotatably mounted in the tool disk installation area. The blocking parts are located between the unfolding limiting part and the retracting limiting part. Rotate the tool tray until the blocking part abuts against the unfolding limit part to put the tool tray into use; Rotate the tool disc until the blocking part abuts against the closing limit part, so that the tool disc is in the closed state.

[0008] By setting a tool tray mounting area at the top of the front ladder frame and incorporating unfolding and folding limiters at the connecting lugs, the tool tray can be unfolded and folded within the mounting area by rotation. This structure allows for tool tray position adjustment without disassembly, effectively solving the problems of large space occupation and inconvenient transportation associated with existing fixed tool trays, as well as the susceptibility to damage and loss of parts in detachable tool trays. The tool tray can be switched between its active and folded states simply by rotating, improving ease of use and storage efficiency.

[0009] The objective of this utility model can also be achieved by the following technical measures: Furthermore, it also includes a rotating shaft, the tool disk having a rotating shaft receiving channel, the connecting ear having a connecting port, the rotating shaft passing through the rotating shaft receiving channel, and the ends of the rotating shaft being inserted into the corresponding connecting ports, so that the tool disk is set in the tool disk mounting area in a rotating manner.

[0010] By setting a shaft receiving channel on the tool tray, and allowing the shaft to pass through this channel and insert into the connecting ear's connector, a reliable rotational connection of the tool tray is achieved. This structure ensures a firm installation and smooth rotation, guaranteeing accurate positioning of the tool tray during rotation and preventing loosening or detachment due to long-term use, thus improving the structural stability and service life of the ladder.

[0011] Furthermore, the tool disk has a shaft receiving channel located near its front end.

[0012] By positioning the shaft receiving channel near the front of the tool disc, the tail end of the tool disc naturally droops under gravity when unfolded, thus ensuring the blocking part stably rests against the unfolding limit part. This design utilizes gravity for automatic limiting, preventing the tool disc from loosening or tipping over during use, thereby improving safety and reliability.

[0013] Furthermore, the connecting ear is provided with a plug-in part, the top of the left ladder tube of the front ladder frame is inserted into the plug-in part of the corresponding connecting ear, so as to connect the left ladder tube of the front ladder frame with the connecting ear, and the top of the right ladder tube of the front ladder frame is inserted into the plug-in part of the corresponding connecting ear, so as to connect the right ladder tube of the front ladder frame with the connecting ear.

[0014] By setting plug-in parts on the connecting ears and inserting the tops of the left and right ladder tubes of the front ladder frame into the corresponding plug-in parts, a reliable assembly between the front ladder frame and the connecting ears is achieved. This structure simplifies and speeds up the assembly process, ensures the strength and stability of the connection parts, provides a stable installation foundation for the tool tray, and contributes to the overall robustness and durability of the ladder structure.

[0015] Furthermore, it also includes bolts, which pass through connecting ears to lock the left ladder tube of the front ladder frame, thereby connecting the left ladder tube of the front ladder frame to the corresponding connecting ear; and bolts pass through connecting ears to lock the right ladder tube of the front ladder frame, thereby connecting the right ladder tube of the front ladder frame to the corresponding connecting ear.

[0016] By inserting bolts through the connecting lugs and locking them into the left and right ladder tubes of the front ladder frame, a detachable and reliable connection is formed between the connecting lugs and the ladder frame. This structure not only enhances the connection strength but also facilitates later maintenance and replacement, further improving the overall stability and service life of the ladder.

[0017] Furthermore, it also includes a platform, with the front ladder frame having spaced-apart steps and the rear ladder frame having spaced-apart treads. One side of the platform is hinged to the ladder frame. When the front and rear ladder frames are unfolded, the other side of the platform rests against the corresponding treads, thus enabling the platform to unfold.

[0018] By incorporating a hinged platform structure into the ladder, when the front and rear ladder frames are extended, one side of the platform is hinged to the frame, while the other side rests against the rungs for support, thus creating a stable working platform during use. This design not only improves safety and comfort during use but also expands the functionality of the ladder, meeting the diverse work needs of users in various scenarios.

[0019] The beneficial effects of this utility model are as follows: This invention features a tool tray mounting area at the top of the front ladder frame, connected by a pivot structure. This allows the tool tray to rotate freely between the unfolding and retracting limiting parts, enabling unfolding and retracting without disassembly. This structure effectively solves the problems of large packaging volume and high transportation costs associated with existing fixed tool trays, as well as the frequent installation, easy damage, or loss of parts associated with detachable tool trays. When retracted, the tool tray fits snugly against the ladder frame without increasing the overall thickness, significantly improving the ladder's storage and portability.

[0020] In this invention, the tool disc's rotating shaft receiving channel is located near the front end, allowing the tail end of the tool disc to naturally droop under gravity when unfolded for use. This ensures the blocking part stably rests against the unfolding limit part, preventing it from tipping over or loosening due to shaking or external force during use. This design utilizes the principle of automatic gravity limiting, achieving structural self-locking and stable support, ensuring safety and reliability during operation.

[0021] This utility model features a compact overall ladder structure. The front and rear ladder frames are foldably connected via connecting lugs, and together with the unfoldable platform structure, a stable working platform can be formed during use. It automatically folds up for storage, making operation simple. Meanwhile, the tool tray has ample capacity to meet the storage needs of various tools, improving the convenience and efficiency of working at heights. The entire ladder can be used and stored without disassembly, greatly improving the user experience. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments: Implementation examples, in conjunction with Figures 1 to 7 As shown, a tool tray rotatable ladder includes a front ladder frame 1, a rear ladder frame 2, a connecting lug 3, and a tool tray 4. The front ladder frame 1 and the rear ladder frame 2 are connected by the connecting lug 3, so that the front ladder frame 1 and the rear ladder frame 2 can be unfolded or folded together. The top of the left ladder tube 12 and the top of the right ladder tube 13 of the front ladder frame 1 form a tool tray mounting area 11. The top of the left ladder tube 12 and the top of the right ladder tube 13 of the front ladder frame 1 are both provided with connecting ears 5. The connecting ears 5 are provided with an unfolding limiting part 51 and a retracting limiting part 52 at the corresponding positions of the tool tray installation area 11. The left and right sides of the tool disk 4 are provided with blocking parts 41. The tool disk 4 is rotatably disposed in the tool disk mounting area 11. The blocking parts 41 are located between the unfolding limiting part 51 and the retracting limiting part 52. Rotate the tool disk 4 until the blocking part 41 abuts against the unfolding limit part 51, so that the tool disk 4 is in the use state; Rotate the tool disk 4 until the blocking part 41 abuts against the closing limit part 52, so that the tool disk 4 is in the closed state.

[0030] Furthermore, it also includes a rotating shaft 6. The tool disk 4 has a rotating shaft receiving channel 42, and the connecting ear 5 has a connecting port 53. The rotating shaft 6 passes through the rotating shaft receiving channel 42, and the ends of the rotating shaft 6 are respectively inserted into the corresponding connecting ports 53, so that the tool disk 4 is set in the tool disk mounting area 11 in a rotating manner.

[0031] Furthermore, the tool disk 4 is provided with the shaft receiving channel 42 near its front end.

[0032] Furthermore, the connecting ear 5 is provided with a plug-in part 54. The top of the left ladder tube 12 of the front ladder frame 1 is inserted into the plug-in part 54 of the corresponding connecting ear 5, so as to connect the left ladder tube 12 of the front ladder frame 1 with the connecting ear 5. The top of the right ladder tube 13 of the front ladder frame 1 is inserted into the plug-in part 54 of the corresponding connecting ear 5, so as to connect the right ladder tube 13 of the front ladder frame 1 with the connecting ear 5.

[0033] Furthermore, it also includes a bolt 10, which passes through the connecting ear 5 to lock the left ladder tube 12 of the front ladder frame 1, thereby connecting the left ladder tube 12 of the front ladder frame 1 with the corresponding connecting ear 5. The bolt 10 passes through the connecting ear 5 to lock the right ladder tube 13 of the front ladder frame 1, thereby connecting the right ladder tube 13 of the front ladder frame 1 with the corresponding connecting ear 5.

[0034] Furthermore, it also includes a platform 7, with the front ladder frame 1 having treads 8 spaced apart, and the rear ladder frame 2 having step sticks 9 spaced apart. One side of the platform 7 is hinged to the ladder frame. When the front ladder frame 1 and the rear ladder frame 2 are unfolded, the other side of the platform 7 abuts against the corresponding step stick 9, thereby enabling the platform 7 to unfold.

[0035] Ladder usage and storage methods: The user first unfolds the front ladder frame 1 and the rear ladder frame 2, and the connecting lugs 3 provide stable support for both, putting the ladder into working condition. One side of the platform 7 is connected to the ladder frame by a hinge, and after unfolding, the other side rests against the rungs 9 of the rear ladder frame 2, thus forming a stable operating platform 7 for the user to stand on or place large tools.

[0036] The tool tray 4 is rotatably mounted via a pivot 6 located at the top of the front ladder frame 1. The user simply rotates the tool tray 4 until its blocking part 41 abuts against the unfolding limit part 51, thus putting the tool tray 4 into use. In this state, the tool tray 4 can be used to hold commonly used tools such as screwdrivers, wrenches, and spare parts. It has ample capacity, is easy to access, and effectively improves the efficiency and safety of working at heights. Because the pivot channel 42 of the tool tray 4 is located near the front end, when the tool tray 4 is in use, its tail end naturally droops under gravity, ensuring that the blocking part 41 remains stably abutted against the unfolding limit part 51. This prevents the tool tray 4 from tipping over or loosening due to shaking or external force during use, further improving stability and safety.

[0037] After use, the user simply rotates the tool tray 4 forward so that the blocking part 41 abuts against the folding limit part 52, allowing the tool tray 4 to fold and fit snugly against the tool tray mounting area 11, thus not increasing the overall thickness of the ladder. Then, the front ladder frame 1 and rear ladder frame 2 are folded away, and the platform 7 is folded away simultaneously to complete the overall storage. This design eliminates the need to disassemble the tool tray 4, avoiding damage or loss of parts caused by frequent disassembly and assembly, effectively reducing packaging and transportation volume, facilitating user storage and handling, and significantly improving the ease of use, stability, and durability of the ladder.
