[0035] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0036] like Figure 1-6As shown, a folding ladder with a detachable tool tray is used in places such as residences, libraries, and building electrical maintenance, making it convenient for users to climb to heights. The folding ladder with a detachable tool tray includes a ladder foot, a step 20, and a tool tray 30. The ladder foot comprises a first ladder foot 10 and a second ladder foot 11. The upper end of the first ladder foot 10 is configured as a U-shape; the second ladder foot 11 is composed of two parallel tube feet connected by a plurality of reinforcing rods 12. The upper ends of the first ladder foot 10 and the second ladder foot 11 are hinged to each other, allowing the first ladder foot 10 and the second ladder foot 11 to be unfolded for use and folded for storage. The lower ends of the first ladder foot 10 and the second ladder foot 11 are supported on the ground.

[0037] More specifically, the pedals 20 are provided in a plurality of pieces, and the pedals 20 are arranged along the length direction of the first ladder foot 10 and the second ladder foot 11. When the first ladder foot 10 and the second ladder foot 11 are unfolded for use, the pedals 20 are installed horizontally along the climbing direction of the first ladder foot 10 and the second ladder foot 11.

[0038] One end of the step 20, mounted at the highest position of the ladder legs, is movably connected to the first leg 10 via a rotating shaft. The other end of this step 20 has a positioning slot 201 defined at its bottom, which engages with the reinforcing rod 12 of the second leg 11. The other end of the step 20, mounted in the middle and lowest position of the ladder legs, is movably connected to the first leg 10 via a pin. The other end of this step 20 is movably connected to the second leg 11 and the steps 20 located on the upper and / or lower levels via a connecting plate 13. Therefore, when using the folding ladder, operating the highest step 20 activates the remaining steps 20 via the connecting plate 13, facilitating the ladder's deployment and folding.

[0039] The tool tray 30 has a tray body 301 and an adapter 302. The overall shape of the tray body 301 is roughly a U-shaped sleeve. The top of the tray body 301 has a receiving cavity 3014 for accommodating tools. The shape of the receiving cavity 3014 includes strip grooves, square grooves and round holes to facilitate the accommodation and placement of various tools.

[0040] In addition, a reversible seat 3015 is provided on the top of the tray body 301. The reversible seat 3015 has a circular hole for inserting and inserting tools such as an electric drill. One end of the reversible seat 3015 is movably connected to a side of the accommodating cavity 3014 via a rotating shaft, so that the reversible seat 3015 can be reversibly inserted above the accommodating cavity 3014. Therefore, when in use, the reversible seat 3015 is flipped outward and extended outside the tray body 301, and then tools can be inserted into the reversible seat 3015. At this time, tools can also be placed in the accommodating cavity 3014. In this way, by adjusting the accommodating cavity 3014 and the structure of the tray body 301, the accommodating space of the tray body 301 can be changed, making it convenient for users to place different types of tools. When not in use, the reversible seat 3015 is flipped and inserted into the accommodating cavity 3014, replacing the space occupied by the entire tray body 301, so that the reversible seat 3015 does not hinder the user's daily use.

[0041] The bottom of the tray body 301 has an assembly groove 3013 that matches the U-shaped tube at the upper end of the first ladder foot 10. When installing the tray body 301, the assembly groove 3013 is inserted into the upper end of the first ladder foot 10 without the use of tools and parts, thereby conveniently and firmly assembling the tray body 301 on the upper end of the first ladder foot 10.

[0042] The left and right connecting ends extending downward from the bottom of the disc body 301 are provided with connecting holes 3011 , and one side surface of the left and right connecting ends of the disc body 301 is provided with a locking hole 3012 connected to the connecting holes 3011 .

[0043] At least two adapters 302 are provided, and the two adapters 302 are respectively mounted on the left and right sides of the first ladder foot 10 and the second ladder foot 11, so that the left and right connection ends of the tray body 301 can be detachably mounted on the ladder foot through the adapters 302. Specifically, the adapter 302 has a first connector 3021 and a second connector 3022.

[0044] The adapter 302 is hinged to the ladder foot through the first connecting head 3021. The first connecting head 3021 has a first hinge hole 30211 and a second hinge hole 30212. The first hinge hole 30211 is communicated with the ends of the first connecting head 3021 and the second connecting head 3022. Therefore, the upper end of the first ladder foot 10 can be passed through the first hinge hole 30211. The first hinge hole 30211 is hingedly connected to the first ladder foot 10 by setting a hinge axis, so that the upper end of the first ladder foot 10 is firmly connected to the first hinge hole 30211 and exposed above the adapter 302, so that the U-shaped upper end of the first ladder foot 10 can be assembled with the disk body 301.

[0045] The second hinge hole 30212 is arranged adjacent to the first hinge hole 30211, and the second hinge hole 30212 extends along the corner of one end of the adapter 302. The upper end of the second ladder foot 11 is inserted into the second hinge hole 30212. The second hinge hole 30212 is hingedly connected to the second ladder foot 11 by setting a hinge axis, so that the upper end of the second ladder foot 11 can be folded or unfolded with the first ladder foot 10 with the hinge axis as the fulcrum.

[0046] The adapter 302 is detachably connected to the tray body 301 via a second connector 3022. The second connector 3022 is provided with a latch 30221. The second connector 3022 can be inserted into the connection holes 3011 at the left and right ends of the tray body 301. The latch 30221 engages with the latch holes 3012 on the connection ends of the tray body 301. Therefore, when the second connector 3022 is inserted into the connection holes 3011 at the ends of the tray body 301, the latch 30221 engages with the latch holes 3012, allowing the tray body 301 to be snap-connected to the adapter 302, thereby achieving the purpose of detachably assembling the tray body 301 onto the first and second ladder legs 10, 11 via the adapter 302.

[0047] Thus, compared to previous implementations where the tool tray 30 could not be removed from the ladder, the present invention facilitates the user to remove and replace different styles of tool trays 30 on the ladder foot through the detachable assembly of the tray body 301 and the ladder foot, providing a user-friendly design. Furthermore, when manufacturing a folding ladder, only the folding ladder or the tool tray 30 need to be manufactured, reducing manufacturing costs. When selling a folding ladder, only the folding ladder with the tool tray 30 can be sold, or the folding ladder and the tool tray 30 can be sold separately. This allows for flexible adjustment of sales strategies, improves marketing effectiveness, and meets the diverse needs of users.

[0048] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
