Description

TECHNICAL FIELD

[0001] The utility model relates to a multifunctional gardening ladder. BACKGROUND

[0002] In the garden work, the use of ladder is very common, especially in the work such as fruit picking, branch pruning, daily maintenance, which need to reach a certain height. However, the traditional ladder (such as long ladder or ladder) has some significant limitations in gardening work. First of all, the traditional ladder is mostly fixed height, which cannot be adjusted according to different work requirements. This fixed height design often causes the problem of unstable ladder feet when facing various complex terrains in the garden, especially the uneven ground, which easily leads to safety accidents.

[0003] In addition, due to the diversity of terrain and operation tasks, the traditional ladder is difficult to provide enough flexibility. For example, when picking fruits at a high place of a tree, the worker needs to adjust the ladder many times according to different heights of fruits, and the height limitation of the fixed ladder makes this adjustment cumbersome and low in work efficiency. At the same time, the foot support of the traditional ladder is easy to tilt on uneven ground, further increasing the risk in use, especially when working on inclined terrain or irregular ground.

[0004] Although some ladders designed specifically for gardening work, such as gardening ladders, have appeared on the market, these ladders are mostly fixed in overall structure, lacking the ability of height adjustment and multi-functional expansion. The existing gardening ladders generally can only provide a single function, such as serving as a common climbing tool, without considering the need for frequent height adjustment and balance maintenance during the work process, making it difficult to cope with different working environments and complex terrains. This often requires the gardening workers to move the ladder many times in actual operation, or use other auxiliary tools to make up for the insufficient functions of the ladder, greatly affecting the work efficiency and safety. SUMMARY

[0005] The purpose of the utility model is to provide a multifunctional gardening ladder that can adapt to different terrains, has height adjustment function and is more safe and stable.

[0015] The locking device of the ladder can lock the front ladder frame or the rear ladder frame at different heights, so that the ladder can be kept stable after the height is adjusted, and the ladder is not easy to slide or deform due to vibration or external force.

[0016] The multifunctional garden ladder is not only suitable for conventional gardening work such as fruit picking and branch pruning, but also suitable for other height operation scenes.

[0017] The purpose of the utility model can also be solved by the following technical measures:

[0018] Further, the rear ladder frame comprises rear ladder pipes opposite to each other and rear steps arranged between the rear ladder pipes;

[0019] The front ladder frame comprises front ladder pipes opposite to each other and front steps arranged between the front ladder pipes.

[0020] Further, the sliding blocks are arranged on the rear ladder pipes of the rear ladder frame in a sliding manner and slide along the length direction of the rear ladder pipes, and the upper ends of the front ladder pipes of the front ladder frame are rotatably connected to the corresponding sliding blocks.

[0021] The sliding blocks are arranged on the rear ladder pipes in a sliding manner and can freely slide along the length direction of the rear ladder pipes. The upper ends of the front ladder pipes of the front ladder frame are rotatably connected to the sliding blocks, so that the front ladder frame can be flexibly adjusted to the required height, and the user can quickly adjust the height of the ladder according to the actual work requirements. This design makes the height adjustment of the ladder more convenient and flexible, and meets the requirements of different gardening work.

[0022] Further, the locking device comprises a clamping seat and a safety hook, the clamping seat is provided with a first clamping hole for accommodating the front steps, the safety hook is provided with a second clamping hole for accommodating the front steps, the clamping seat is arranged on the rear ladder pipe, the first clamping hole faces downward, and the safety hook is movably arranged on the rear ladder pipe close to the clamping seat;

[0023] The corresponding front step of the front ladder frame enters the first clamping hole;

[0024] The safety hook is rotated to make the corresponding front step of the front ladder frame enter the second clamping hole, so as to lock the relative position of the front ladder frame and the rear ladder frame;

[0025] The safety hook is rotated to make the second clamping hole leave the corresponding front step of the front ladder frame to release the relative position locking of the front ladder frame and the rear ladder frame.

[0026] Through the double locking structure of the clamping seat and the safety hook, the relative position of the ladder frame part is firmly fixed, so that the structure of the ladder is prevented from loosening or accidentally tilting during work, and the stability of the ladder and the safety of the work are greatly improved.

[0027] The first clamping hole of the clamping seat and the second clamping hole of the safety hook form double protection, and when the front step of the front ladder frame enters the two clamping holes, the relative position of the front ladder frame and the rear ladder frame is accurately locked, and this double locking mechanism effectively prevents the ladder from moving accidentally during use.

[0028] The design of the rotating safety hook enables the user to easily complete the locking and unlocking operation of the ladder, ensures the convenience and flexibility during use, especially when frequently converting the height or unfolding / folding state of the ladder, simplifies the operation process and saves time.

[0029] The double-cartridge design reduces the risk of accidental deployment or folding of the ladder due to failure of a single locking device, significantly reducing the probability of misuse and ensuring the safety of users in different operating scenarios.

[0030] The locking device not only applies to ladder adjustments of different heights and angles, but also suits various complex terrains and operating needs. Users can easily adjust the state of the ladder according to the use environment, ensuring stability during high-altitude operations.

[0031] Further, the balancing device includes a balancing rod and a fine-tuning grip foot piece, which is arranged at the bottom of the balancing rod.

[0032] The fine-tuning grip foot piece is arranged at the bottom of the balancing rod, and can be fine-tuned according to the actual situation of the ground. Whether it is a flat ground or an irregular terrain such as a pothole or a slope, the grip foot piece can effectively grip the ground, enhancing the ground adaptability of the ladder. This design ensures the stability of the ladder on various complex terrains, reducing the risk of tilting or sliding of the ladder during use.

[0033] The firm contact of the grip foot piece with the ground, through the fine-tuning function of the grip foot piece, allows users to further adjust the balance of the ladder during use. The cooperation of the balancing rod and the grip foot piece can effectively disperse the gravity of the ladder, ensuring that the ladder remains stable at any height and inclination angle, reducing the problem of traditional ladders easily tilting or shaking on uneven ground.

[0034] The improved grip ability of the grip foot piece greatly enhances the safety of the ladder. Especially during high-altitude operations, the balance and stability of the ladder are key factors to ensure safety. Through the design of the balancing device, the ladder can maintain stability under various ground conditions, thereby reducing safety accidents caused by uneven ground or unstable foot support, protecting the safety of operating personnel.

[0035] The design of the balancing rod and the grip foot piece not only applies to various ground conditions in garden operations, but also can cope with different terrain needs in other scenarios. This design increases the flexibility of the ladder, making its application range more extensive, not limited to gardening operations, but can be extended to construction, maintenance and other fields that require high-altitude operations.

[0036] Further, a fastener is also included, the balancing device includes a balancing rod and a micro-adjustable grip foot, the micro-adjustable grip foot is arranged at the bottom of the balancing rod, the lower end of the front ladder pipe is provided with a clamping opening, the front ladder pipe is provided with a lock hole corresponding to the clamping opening position, the balancing rod is inserted into the clamping opening, the balancing rod is moved to make the lock hole communicate with the corresponding through hole, and the fastener is sequentially threaded through the lock hole and the through hole and locked, so that the front ladder frame and the balancing device are connected.

[0037] This design is particularly improved for the case of unbalanced ladder feet on uneven ground during gardening work. By configuring multiple groups of through holes on the balancing rod, and through the clamping opening and lock hole of the front ladder pipe corresponding to the through holes of the balancing rod, users can flexibly adjust the connection between the ladder and the balancing rod according to different terrain conditions. Moving the balancing rod ensures that the ladder feet are balanced at different heights and inclination angles. The locking function of the fastener ensures that after adjustment, the structure of the ladder is still stable, preventing shaking or tilting due to uneven ground.

[0038] Through the design of multiple groups of through holes in the balancing rod, the ladder can be adjusted according to different inclined terrain and height requirements, making it more widely adaptable. Under different terrain conditions, users can easily adjust the height of the ladder feet to ensure stable use of the ladder in complex environments. Whether it is an inclined ground, a stone road, or an irregular natural ground, this design can ensure that the ladder is firmly gripped, improving the stability and safety of ladder use.

[0039] The balancing rod and the front ladder frame are locked by the fastener, so that the ladder can maintain high structural stability after adjustment. After the fastener is threaded through the lock hole and the through hole, it is firmly locked with the front ladder frame and the balancing device, ensuring that the balancing rod does not loosen or displace during use, greatly improving safety during work, especially during high-altitude work, preventing accidents or structural instability from causing safety hazards.

[0040] The balancing rod has a micro-adjustable grip foot that can quickly adjust the balance of the ladder through simple operation.

[0041] Further, the bottom of the telescopic support foot is provided with a micro-adjustable grip foot.

[0042] The micro-adjustable grip foot can make fine adjustments according to the unevenness of the ground, ensuring that the ladder firmly grips the ground during use, especially in complex environments such as potholes or slopes, the ladder can still maintain stability, preventing sliding or tilting, and improving work safety.

[0043] The fine-tuning function allows users to adjust the angle and height of the gripping feet flexibly under different ground conditions, enabling the ladder to adapt to various complex terrain environments such as soft muddy ground, gravel road, or inclined terrain. Regardless of the height difference or angle change of the ground, the gripping feet of the ladder can be adjusted as needed to ensure the stability of the ladder.

[0044] The fine-tuning function of the gripping feet effectively reduces the safety hazards caused by uneven ground during the use of the ladder. By adjusting the gripping feet, it can ensure that all foot points of the ladder are in close contact with the ground, eliminating any instability and avoiding accidents caused by ladder shaking or tilting for the workers.

[0045] The design of the fine-tuning gripping feet allows users to quickly and conveniently adjust according to the ground conditions, with simple operation and without the need for complex tools or excessive time. This design improves the efficiency of the work, especially in gardening work that requires frequent movement of the ladder, reducing time and labor costs.

[0046] Through the fine-tuning function of the gripping feet, the ladder can be safely used in more scenarios, no longer limited to flat ground conditions. Whether it is an orchard, garden, or outdoor scene, users can stably use the ladder on various terrains, greatly expanding the applicability and use scenarios of the ladder.

[0047] Further, a support sheet is provided, with the upper end of the support sheet being rotatably connected to the center of the platform, and the lower end of the support sheet being detachably connected to the rear ladder frame.

[0048] Further, an iron chain is provided, with the iron chain being connected to the rear step near the lower end of the rear ladder frame, and the telescopic support foot being provided with a chain buckle, and the other end of the iron chain being connected to the chain buckle when the ladder frame part and the telescopic support foot are unfolded.

[0049] The iron chain connects the rear step at the lower end of the rear ladder frame and the telescopic support foot, and is fixed through the chain buckle. When the ladder frame part and the telescopic support foot are unfolded, the length of the iron chain limits the maximum unfolding angle of the ladder, preventing the ladder from losing stability due to excessive unfolding. This can effectively avoid the structural imbalance of the ladder caused by excessive unfolding during operation, improving the safety during use.

[0050] The addition of the iron chain provides additional support for the ladder frame part and the telescopic support foot. Even if the ladder is used in complex ground environments, the tension of the iron chain can ensure that the ladder frame part and the telescopic support foot remain stably connected, further enhancing the overall stability of the ladder. Especially during high-altitude operations, the safety of the ladder is particularly important, and the connection of the iron chain provides higher safety protection for the user.

[0051] The iron chain is connected with the telescopic supporting leg through a chain buckle, which is simple in design and easy to disassemble and assemble. Users can quickly connect or release the iron chain according to actual needs, so as to realize the folding or unfolding of the ladder and facilitate flexible use in different scenes. At the same time, the length of the iron chain is reasonably designed, which not only ensures the stability during use, but also does not affect the overall operation and adjustment function of the ladder. Through the additional protection of the iron chain, the structure of the ladder is more stable in complex terrain or high-altitude operation, reducing the safety risks caused by excessive unfolding, shaking or other accidental operations of the ladder. This safety design provides more protection for users, especially in high-altitude operation or uneven terrain operation, further reducing the incidence of accidents.

[0052] Further, the balance bar is an arc-shaped balance bar.

[0053] The arc-shaped balance bar design makes the ladder still stable on an inclined ground or a bumpy terrain, and the fine adjustment function of the ground gripping piece can adapt to different ground height differences, ensuring that the ladder can operate stably in various complex environments.

[0054] The beneficial effects of the utility model are as follows:

[0055] The utility model discloses a slidable structure of the sliding block and the front ladder frame, which realizes the free adjustment of the height of the ladder frame part, and users can adjust the height of the ladder according to the operation requirements, and the ladder can be flexibly adapted to different gardening operation scenes, such as actual picking and high-altitude pruning.
