Description
Technical Field
[0001] This utility model relates to the field of garden maintenance technology, specifically a new type of garden ladder for garden maintenance. Background Technology
[0002] Garden maintenance refers to the technical measures taken to improve the growth of garden plants and enhance their ornamental value. When maintaining taller plants in a garden, garden ladders are used to help climb to higher positions so that taller trees can be pruned and maintained.
[0003] However, current garden ladders used for garden maintenance are not convenient for users to adjust their height. For example, a novel garden ladder for garden maintenance, as described in Chinese Patent Publication No. CN217632224U, includes a first ladder frame. The front of the first ladder frame has a sliding groove, and the inner wall of the sliding groove has a slot. A positioning rod is movably connected to the inner wall of the slot. A second ladder frame is movably connected to the front of the first ladder frame. A slider is fixedly connected to the back of the second ladder frame. A connecting rod is fixedly connected to the top of the second ladder frame. One end of the connecting rod is fixedly connected to a connecting shaft, and a movable sleeve is movably connected to the outer wall of the connecting shaft. This novel garden ladder for garden maintenance facilitates user adjustment during use. It can be adjusted according to the maintenance height to meet usage needs, bringing convenience to users' garden maintenance work and increasing flexibility in use, thereby greatly improving the effectiveness of the garden ladder and making it more convenient for users.
[0004] This garden ladder uses a positioning rod and slots to adjust its height, essentially a segmented adjustment system. The fixed interval between adjacent slots means that height adjustments can only be made between preset discrete values. For example, if a user needs to prune and maintain garden plants of different heights, and the target height happens to be between two preset levels, the desired height cannot be precisely matched. Furthermore, this adjustment method means that the minimum adjustment range is determined by the slot spacing, making it impossible to achieve small, continuous height changes. Utility Model Content
[0005] The purpose of this utility model is to provide a new type of garden ladder for garden maintenance, so as to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A novel garden ladder for garden maintenance includes a pair of first uprights, with several first crossbars connecting the pair of first uprights. The sides of the pair of first uprights have grooves, and second uprights slide within each groove. Several second crossbars connect the second uprights. Each of the second uprights has a rack installed on its opposite side, and each of the first uprights has a connecting sleeve installed on its opposite side. A gear is rotatably connected inside the connecting sleeve, meshing with the rack. A rotating shaft is rotatably connected to the side of the connecting sleeve, rotatably connected to the gear. A handle is installed at the free end of the rotating shaft, and a fixing member is provided on the outside of the rotating shaft to lock its rotation. This allows for stepless adjustment of the garden ladder's height, enabling users to precisely adjust the height according to their needs without being limited by fixed stops, improving flexibility and adaptability, and better meeting the height requirements of different garden maintenance scenarios.
[0008] Furthermore, the first upright is fixed to the ground with screws located in a groove.
[0009] Furthermore, the fixing component includes a first anti-loosening washer installed on the side of the connecting sleeve and a second anti-loosening washer sliding on the outside of the rotating shaft. The first and second anti-loosening washers engage with each other. The fixing component also includes a pressing member, which presses the second anti-loosening washer to effectively prevent the rotating shaft from rotating accidentally due to vibration or external force during the use of the garden ladder, ensuring that the height of the garden ladder remains stable after adjustment, and further improving the safety and reliability of the garden ladder.
[0010] Furthermore, a limiting groove is formed on the surface of the rotating shaft, and a limiting block is installed on the inner ring of the second anti-loosening washer. The limiting block slides in the limiting groove, and a fixing block is installed inside the limiting groove. A bolt is threadedly connected to the fixing block, and one end of the bolt presses against the limiting block to further enhance the locking effect of the fastener. By pressing the limiting block with the bolt, the engagement between the second anti-loosening washer and the first anti-loosening washer becomes tighter. Moreover, the cooperation between the limiting groove and the limiting block can also limit the axial displacement of the second anti-loosening washer, thereby improving the stability and reliability of the fastener.
[0011] Furthermore, the gear, shaft, first anti-loosening washer, and second anti-loosening washer are coaxially arranged to ensure smoother force transmission, reduce friction and energy loss caused by misalignment of components, and improve the ease of operation and stability of height adjustment of the garden ladder. The coaxial arrangement also facilitates the installation and coordination of various components, simplifies the structure of the garden ladder, and improves the overall reliability.
[0012] Furthermore, positioning strips are installed on the sides of the second uprights that are close to each other, and positioning grooves are opened on the side of the slide. The positioning strips slide in the positioning grooves, making the sliding of the second uprights in the slide more stable and smooth, avoiding the second uprights from deviating or shaking during the sliding process, further improving the stability and reliability of the height adjustment of the garden ladder, and also helping to extend the service life of the garden ladder.
[0013] Furthermore, the first crossbar is disposed between a pair of first uprights, and the second crossbar is disposed on the side of a pair of second uprights to prevent the first and second crossbars from contacting each other when the second uprights slide.
[0014] Furthermore, the surface of the handle is covered with an anti-slip sleeve, which increases the friction between the user's hand and the handle, preventing the hand from slipping when turning the handle to adjust the height of the garden ladder, improving the safety and convenience of operation, and enabling the user to control the height adjustment of the garden ladder more easily and accurately.
[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This novel garden ladder for garden maintenance achieves stepless height adjustment through the meshing transmission of gears and racks, combined with a handle and a rotating shaft. Users can precisely adjust the height of the garden ladder according to the actual height of trees in different garden maintenance scenarios, breaking through the limitations of traditional segmented adjustment and meeting any height requirement, greatly improving the flexibility and adaptability of use. For example, when pruning flowers or trees of different heights, the garden ladder can be easily adjusted to the appropriate height, improving work efficiency. Attached Figure Description

Detailed Implementation
[0021] 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.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a novel garden ladder for garden maintenance, comprising a pair of first uprights 1, with several first crossbars 2 connected between the pair of first uprights 1, and a sliding groove 7 on the side of the pair of first uprights 1, with second uprights 3 sliding inside each of the sliding grooves 7, several second crossbars 4 connected between the second uprights 3, and a rack 5 installed on the side of each of the second uprights 3 that is far apart from each other. A connecting sleeve 6 is installed on the side of each of the first uprights 1 that is far apart from each other, and a gear 8 is rotatably connected inside the connecting sleeve 6, with the gear 8 meshing with the rack 5. A rotating shaft 11 is rotatably connected to the side of the connecting sleeve 6, with the rotating shaft 11 rotatably connected to the gear 8, and the rotating shaft 11 is free. A handle 12 is installed at one end, and a fixing member is provided on the outside of the rotating shaft 11. The fixing member is used to lock the rotation of the rotating shaft 11. When the user turns the handle 12, the rotating shaft 11 is driven to rotate, and the rotating shaft 11 in turn drives the gear 8 connected to it to rotate in the connecting sleeve 6. Since the gear 8 meshes with the rack 5 on the second upright 3, the rotation of the gear 8 will cause the rack 5 to drive the second upright 3 to slide up and down in the slide groove 7 of the first upright 1, thereby realizing the adjustment of the height of the garden ladder. After adjusting to a suitable height, the rotating shaft 11 is locked by the fixing member, so that the gear 8 cannot rotate, thereby fixing the height at the adjusted position. At this time, the user can climb the forest ladder fixed to the ground to maintain the trees.
[0023] As an embodiment of this utility model, the fixing member further includes a first anti-loosening washer 9 installed on the side of the connecting sleeve 6 and a second anti-loosening washer 10 sliding on the outside of the rotating shaft 11. The first anti-loosening washer 9 and the second anti-loosening washer 10 engage with each other. The fixing member also includes a pressing member, which presses the second anti-loosening washer 10 to make the second anti-loosening washer 10 tightly engage with the first anti-loosening washer 9, thereby increasing the resistance to the rotation of the rotating shaft 11 and locking the rotating shaft 11 so that it cannot rotate.
[0024] As an embodiment of this utility model, a limiting groove 13 is further provided on the surface of the rotating shaft 11, and a limiting block is installed on the inner ring of the second anti-loosening washer 10. The limiting block slides in the limiting groove 13, and a fixing block 14 is installed inside the limiting groove 13. A bolt 15 is threadedly connected to the fixing block 14. One end of the bolt 15 presses against the limiting block. Rotating the bolt 15 causes it to move towards the limiting block and press against the limiting block. After being forced, the limiting block pushes the second anti-loosening washer 10, making it more tightly engaged with the first anti-loosening washer 9. At the same time, the limiting block slides in the limiting groove 13, restricting the axial movement of the second anti-loosening washer 10 and ensuring the stable operation of the fixing component.
[0025] As an embodiment of this utility model, the gear 8, the rotating shaft 11, the first anti-loosening washer 9, and the second anti-loosening washer 10 are further arranged on the same axis. With the coaxial arrangement, the rotating shaft 11 can drive the gear 8 to rotate more efficiently when it rotates, and the first anti-loosening washer 9 and the second anti-loosening washer 10 can interact better to achieve stable locking of the rotating shaft 11 and avoid jamming or shaking caused by the misalignment of the components.
[0026] As an embodiment of this utility model, the second uprights 3 are further provided with positioning strips 17 on their adjacent sides, and positioning grooves 16 are provided on the side of the slide groove 7. The positioning strips 17 slide in the positioning grooves 16, which serves as a guide and limiter, restricting the lateral displacement of the second uprights 3 and ensuring that the second uprights 3 can only slide up and down along the direction of the slide groove 7, thus ensuring the stability of the garden ladder height adjustment process.
[0027] In one embodiment of this utility model, the first crossbar 2 is further disposed between a pair of first uprights 1, and the second crossbar 4 is disposed on the side of a pair of second uprights 3.
[0028] As an embodiment of this utility model, the surface of the handle 12 is further covered with an anti-slip sleeve. The surface material of the anti-slip sleeve has a large coefficient of friction. When the user holds the handle 12, a large frictional force is generated between the anti-slip sleeve and the hand, ensuring that the user can apply force stably during the rotation of the handle 12 and avoiding operational errors caused by hand slippage.
[0029] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuits of the mold temperature controller, temperature controller, water pump, pump, solenoid valve, heater, generator, condenser, absorber and evaporator can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
