Description

Technical Field

[0001] This application belongs to the field of indoor equipment, and specifically relates to an A-frame ladder with a toolbox. Background Technology

[0002] With the increasing prevalence of apartment buildings, people's living space has generally shrunk, leading to higher demands for space utilization of commonly used indoor equipment. Folding ladders are a practical tool for indoor use, taking up little space and being highly portable, making them useful in both renovations and daily life. However, due to their portability, they need to be used with a separate toolbox. Since the toolbox is not easy to secure, it is difficult to retrieve tools, requiring frequent climbing up and down the ladder. Simply placing the toolbox on the ladder poses a safety hazard when using the ladder. There are existing technologies that allow toolboxes to be mounted on folding ladders, but these either increase the space required or result in small toolboxes that lack practicality due to space constraints. Utility Model Content

[0003] To address the aforementioned issues, this application proposes an A-frame ladder with a toolbox, comprising a ladder body and a support frame rotatably connected to the ladder body via a pivot, and further comprising a toolbox and a connecting assembly;

[0004] There is a gap at the top of the ladder, and the connecting components are located in the gap.

[0005] The connecting component is connected to the toolbox. When the ladder and support frame are unfolded, the connecting component fixes the toolbox to the top surface of the ladder.

[0006] When the ladder and support frame are combined, the connecting assembly secures the toolbox to the empty space.

[0007] When not in use, the support frame and ladder are stored together, with the toolbox fixed in the empty space of the ladder, without affecting the overall footprint of the ladder. When in use, as the ladder and support frame unfold, the toolbox automatically moves to the top of the ladder under the action of the connecting components, making it convenient for workers standing on the ladder to use.

[0008] Furthermore, the connecting assembly includes a transmission component; the transmission component is connected between the rotating shaft and the toolbox, and the transmission component moves the toolbox by rotating with the rotating shaft. The transmission component realizes the movement of the toolbox by transmitting the rotation of the ladder and the support frame to the toolbox.

[0009] Furthermore, transmission components are installed on the shafts on both sides of the ladder. The transmission components on both sides are connected to the tool box, which can share the pressure, reduce the load on the transmission components, and extend their service life.

[0010] Furthermore, the connecting assembly also includes a lifting component, which is located between the tool box and the transmission component. The tool box can move along the lifting component, and the lifting component allows the tool box to be adjusted to different heights, making it convenient for workers to adjust the tool box to a suitable height according to their different positions on the ladder.

[0011] Furthermore, the toolbox includes a box body, inside which are a material section and a tool section. The material section has a cover, and the tool section has a fixing component. The material section contains parts, and the fixing component secures repair tools. The material section of the toolbox can hold small materials such as parts, while the tool section holds slightly larger tools such as screwdrivers, pliers, wrenches, and brushes.

[0012] Furthermore, the transmission components include a driving gear, a driven gear, and a connecting member; the driving gear is connected to the rotating shaft and rotates simultaneously with the rotating shaft, the driven gear meshes with the driving gear, the tooth diameter of the driven gear is smaller than the tooth diameter of the driving gear, the driven gear is connected to the connecting member, the connecting member rotates synchronously with the driven gear, and the connecting member is connected to the tool box;

[0013] During the unfolding of the support frame and the ladder, the support frame will rotate around the pivot. If this rotation direction is set to counterclockwise, then the drive gear and the support frame will rotate synchronously, and the drive gear will also rotate counterclockwise. When the driven gear meshes with the drive gear, the drive gear will rotate clockwise. The connecting piece and the driven gear will rotate synchronously, so the connecting piece will swing clockwise. In other words, the toolbox will move clockwise from the empty space to the top of the ladder, that is, move towards the top of the ladder, and finally be fixed in one side of the ladder.

[0014] Furthermore, the transmission components include a driving gear, a driven gear, a reversing gear, and a connecting member; the driving gear is connected to the rotating shaft and rotates simultaneously with the rotating shaft, the driven gear meshes with the driving gear, the tooth diameter of the driven gear is smaller than the tooth diameter of the driving gear, the reversing gear meshes with the driven gear, the reversing gear is connected to a connecting member, the connecting member rotates synchronously with the driven gear, and the connecting member is connected to the tool box.

[0015] With the reversing gear installed, the support frame will rotate around the pivot point during the unfolding of the support frame and ladder. If this rotation direction is set to counterclockwise, the driving gear and the support frame will rotate synchronously, and the driving gear will also rotate counterclockwise. When the driven gear meshes with the driving gear, the driving gear will rotate clockwise. When the reversing gear meshes with the driven gear, the reversing gear will rotate counterclockwise. The connecting piece and the reversing gear will rotate synchronously, so the connecting piece will swing counterclockwise. In other words, the toolbox will move counterclockwise from the empty space to the top of the ladder, that is, move away from the top of the ladder. Finally, it will be fixed in one position on the side of the support frame. Compared with the absence of the reversing gear, the toolbox on one side of the support frame will not affect the use of the ladder, making it more convenient to use.

[0016] Furthermore, the lifting component includes a scissor lift structure and a locking buckle. The scissor lift structure is connected to the tool box. The scissor lift structure is equipped with a locking buckle for fixing the scissor lift structure. When the scissor lift structure retracts, the tool box moves from the bottom to the top surface. When the scissor lift structure extends, the tool box moves from the top surface to the bottom surface. After adjusting to the appropriate position, the locking buckle is used to fix the scissor lift structure to each other so that it cannot extend or retract, thereby fixing the position of the tool box.

[0017] Furthermore, lifting components are located on the side of the toolbox and connected to the transmission components, with lifting components provided on both sides of the toolbox.

[0018] Furthermore, the material section includes multiple material cavities, and a cover is placed over the material cavities to seal them, preventing the internal parts of the toolbox from spilling out during movement.

[0019] Furthermore, the tool section includes a tool cavity, a fixing member is located inside the tool cavity, the fixing member is provided with a tool groove, the repair tool is fixed in the tool groove, the tool can be directly pulled out from the tool groove for use, and the tool is not easy to fall out when placed.

[0020] Furthermore, the tooth diameter ratio between the driving gear and the driven gear is adapted to the angle change ratio of the toolbox and the support frame. The tooth diameter ratio of the driving gear and the driven gear can affect the movement distance of the toolbox. The unfolding angle of the support frame and the ladder is a fixed value. Therefore, by using the transmission of gears to amplify the movement angle of the connecting parts, those skilled in the art can set the tooth diameter ratio of the driving gear and the driven gear according to the actual size of the ladder so that the toolbox can move smoothly from the empty space to the top surface of the ladder.

[0021] The beneficial effects of this utility model are as follows:

[0022] (1) The tool box is set in the space of the ladder body of the A-frame ladder. This not only avoids the problem of frequently going up and down the ladder to get tools when using the A-frame ladder, but also does not increase the space occupied by the A-frame ladder. It improves the practicality without affecting the storage.

[0023] (2) The ladder toolbox is flexible to move and can be used in a suitable position, which enhances the convenience of use and improves work efficiency. Attached Figure Description

[0038] like Figure 1-7 As shown, an A-frame ladder with a toolbox 4 includes a ladder body 1 and a support frame 2 rotatably connected to the ladder body 1 via a pivot 21, and also includes a toolbox 4 and a connecting assembly 3;

[0039] There is a space 11 at the top of ladder 1, and the connecting component 3 is located at space 11;

[0040] The connecting component 3 is connected to the tool box 4. When the ladder 1 and the support frame 2 are unfolded, the connecting component 3 fixes the tool box 4 to the top surface of the ladder 1.

[0041] When the ladder 1 and the support frame 2 are combined, the connecting component 3 fixes the tool box 4 to the space 11.

[0042] When not in use, the support frame 2 and the ladder 1 are stored together, and the tool box 4 is fixed in the space 11 of the ladder 1, without affecting the overall floor space of the ladder 1. When in use, as the ladder 1 and the support frame 2 are unfolded, the tool box 4 is automatically moved to the top of the ladder 1 by the connecting component 3, making it convenient for workers standing on the ladder to use.

[0043] In one embodiment, the connecting component 3 includes a transmission component 31; the transmission component 31 is connected between the rotating shaft 21 and the tool box 4, and the transmission component 31 rotates with the rotating shaft 21 to move the tool box 4. The transmission component 31 realizes the movement of the tool box 4 by transmitting the rotation of the ladder 1 and the support frame 2 to the tool box 4.

[0044] Depending on the different transmission components, a specific embodiment may be provided, such as... Figure 3 As shown, the transmission component 31 includes a driving gear 311, a driven gear 312, a reversing gear 313, and a connecting member 314. The driving gear 311 is connected to the rotating shaft 21 and rotates simultaneously with the rotating shaft 21. The driven gear 312 meshes with the driving gear 311, and the tooth diameter of the driven gear 312 is smaller than that of the driving gear 311. The reversing gear 313 meshes with the driven gear 312. The reversing gear 313 is connected to the connecting member 314, and the connecting member 314 rotates synchronously with the driven gear 312. The connecting member 314 is connected to the tool box 4.

[0045] With the reversing gear 313 in place, during the unfolding of the support frame 2 and the ladder 1, the support frame 2 will rotate around the pivot 21. If this rotation direction is set to counterclockwise, then the driving gear 311 and the support frame 2 will rotate synchronously, and the driving gear 311 will also rotate counterclockwise. When the driven gear 312 meshes with the driving gear 311, the driving gear 311 will rotate clockwise. When the reversing gear 313 meshes with the driven gear 312, the reversing gear 313 will rotate counterclockwise. The connecting piece 314 and the reversing gear 313 will rotate synchronously, so the connecting piece 314 will swing counterclockwise. That is to say, the toolbox 4 will move counterclockwise from the space 11 to the top surface of the ladder 1, that is, move away from the top surface of the ladder 1. Finally, the fixed position is located on one side of the support frame 2. Compared with the absence of the reversing gear 313, the toolbox 4 on the side of the support frame 2 will not affect the use of the ladder 1, making it more convenient to use.

[0046] Another specific embodiment, such as Figure 4 As shown, the transmission component 31 includes a driving gear 311, a driven gear 312, and a connecting member 314. The driving gear 311 is connected to the rotating shaft 21 and rotates simultaneously with the rotating shaft 21. The driven gear 312 meshes with the driving gear 311. The tooth diameter of the driven gear 312 is smaller than that of the driving gear 311. The driven gear 312 is connected to the connecting member 314. The connecting member 314 rotates synchronously with the driven gear 312. The connecting member 314 is connected to the tool box 4.

[0047] During the unfolding of the support frame 2 and the ladder 1, the support frame 2 will rotate around the pivot 21. If this rotation direction is set to counterclockwise, then the drive gear 311 and the support frame 2 will rotate synchronously, and the drive gear 311 will also rotate counterclockwise. When the driven gear 312 meshes with the drive gear 311, the drive gear 311 will rotate clockwise. The connecting piece 314 and the driven gear 312 will rotate synchronously, so the connecting piece 314 will swing clockwise. That is to say, the toolbox 4 will move clockwise from the space 11 to the top surface of the ladder 1, that is, move towards the top surface of the ladder 1, and finally be fixed in one side of the ladder 1.

[0048] In a preferred embodiment, the shafts 21 on both sides of the ladder 1 are equipped with transmission components 31. The transmission components 31 on both sides are connected to the tool box 4 to share the pressure, reduce the load on the transmission components 31, and extend their service life.

[0049] In one specific embodiment, the tooth diameter ratio between the driving gear 311 and the driven gear 312 is adapted to the angle change ratio between the tool box 4 and the support frame 2. The tooth diameter ratio between the driving gear 311 and the driven gear 312 can affect the movement distance of the tool box 4. The unfolding angle between the support frame 2 and the ladder 1 is a fixed value. Therefore, by using the gear transmission to amplify the movement angle of the connecting member 314, those skilled in the art can set the tooth diameter ratio between the driving gear 311 and the driven gear 312 according to the actual size of the ladder 1 so that the tool box 4 can move smoothly from the space 11 to the top surface of the ladder 1.

[0050] In one embodiment, such as Figure 5 As shown, the connecting component 3 also includes a lifting member 32, which is located between the tool box 4 and the transmission member 31. The tool box 4 can move along the lifting member 32. By setting the lifting member 32, the tool box 4 can be adjusted to different heights, so that the staff can adjust the tool box 4 to a suitable height according to the different positions of the ladder 1.

[0051] In a preferred embodiment, the lifting member 32 is disposed on the side of the tool box 4 and connected to the transmission member 31, and the transmission member 31 and the lifting member 32 are disposed on both sides of the tool box 4.

[0052] One specific embodiment, such as Figure 5 As shown, the lifting component 32 includes a scissor structure 321 and a locking buckle 322. The scissor structure 321 is connected to the tool box 4. The scissor structure 321 is provided with a locking buckle 322 for fixing the scissor structure 321. When the scissor structure 321 retracts, the tool box 4 moves from the bottom to the top surface. When the scissor structure 321 extends, the tool box 4 moves from the top surface to the bottom surface. After adjusting to a suitable position, the locking buckle 322 is used to fix the scissor structure 321 to each other so that it cannot extend or retract, thereby fixing the position of the tool box 4.

[0053] In one embodiment, such as Figure 6 As shown, the toolbox 4 includes a box body, inside which are a material section 41 and a tool section 42. The material section 41 is provided with a cover 412, and the tool section 42 is provided with a fixing member 422. The material section 41 contains parts, and the fixing member 422 fixes repair tools. The material section 41 of the toolbox 4 can hold small materials such as parts, while the tool section 42 holds slightly larger tools such as screwdrivers, pliers, wrenches, and brushes.

[0054] One specific embodiment, such as Figure 6As shown, the material section 41 includes multiple material cavities 411, and the cover 412 covers the material cavities 411 to seal the material cavities 411, preventing the internal parts of the tool box 4 from spilling during movement.

[0055] One specific embodiment, such as Figure 6-7 As shown, the tool part 42 includes a tool cavity 421, a fixing member 422 located in the tool cavity 421, and a tool groove 423 provided in the fixing member 422. The repair tool is fixed in the tool groove 423. When in use, the tool can be directly pulled out in the tool groove 423. When placed, the tool is stuck in the tool groove 423 and is not easy to fall out.

[0057] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0058] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.
