Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-6 , the present invention provides a technical solution:

[0029] An A-frame ladder for preventing tools from falling includes two leg bodies 1. The tops of the two leg bodies 1 are fixedly connected with storage boxes 2. Limiting mechanisms 3 are arranged on the front side and the rear side of the storage box 2, and magnetic balls 4 are arranged inside the storage box 2;

[0030] The limiting mechanism 3 includes four limiting columns 301, a limiting block 302 and a limiting box 303. One side of the limiting column 301 close to the limiting block 302 is fixedly connected with the limiting block 302. The surface of the limiting block 302 is in movable contact with the inner wall of the limiting box 303. One side of the limiting box 303 close to the storage box 2 is fixedly connected with the storage box 2.

[0031] In this embodiment: By inserting commonly used tools into the limiting box 303 for placement, at this time, the limiting block 302 can be squeezed by the commonly used tools. By sliding the limiting column 301 inside the through hole 7, the limiting block 302 can be moved, so that the spring 8 is compressed. At this time, the elastic force of the spring 8 can squeeze the limiting block 302 to clamp the commonly used tools, so that the commonly used tools can be limited inside the limiting box 303, avoiding accidental dropping of the tools, facilitating the taking and placing of the commonly used tools. Small metal tools and screws can be placed inside the storage box 2 and magnetically attracted by the magnetic balls 4, further enhancing the fixing effect on the tools and screws, avoiding the problem that the tops of the left leg and the right leg in the prior art solution do not have a structure for storing and limiting tools. When a worker climbs on the A-frame ladder and uses tools for operation, when temporarily placing the tools, the tools are likely to accidentally fall, and it is necessary to return to the ground to pick them up, which is rather inconvenient, and the dropped tools are likely to cause injury to the ground personnel, posing a safety hazard.

[0032] Specifically, asFigure 3 As shown, through holes 7 are formed inside the limit box 303, and the number of the through holes 7 is four. The limit posts 301 are movably connected inside the through holes 7.

[0033] Specifically, as Figure 3 and Figure 4 shown, a spring 8 is movably sleeved on the surface of the limit post 301. One side of the spring 8 close to the limit block 302 contacts the limit block 302, and one side of the spring 8 close to the inner wall of the storage box 2 contacts the inner wall of the storage box 2.

[0034] Specifically, as Figure 1 、 Figure 3 and Figure 4 shown, a chamfer is formed on one side of the top of the limit block 302 close to the storage box 2.

[0035] In this embodiment: The limit post 301 is slidably connected inside the through hole 7, so that the limit post 301 and the limit block 302 can move. The elastic force of the spring 8 can be used to push the limit block 302 to clamp the common tools. By forming a chamfer on one side of the top of the limit block 302 close to the storage box 2, it is convenient to insert the common tools into the limit box 303.

[0036] Specifically, as Figure 5 shown, a sealing mechanism 5 is arranged on the top of the right storage box 2. The sealing mechanism 5 includes a sliding cover 501, a first glass 502 and a handle 503. The first glass 502 is embedded inside the sliding cover 501, and the handle 503 is bonded to the top of the first glass 502.

[0037] Specifically, as Figure 1 and Figure 2 shown, clamping blocks 10 are fixedly connected to the front side and the rear side of the storage box 2. The sliding cover 501 is slidably connected between the opposite sides of the two clamping blocks 10 on the right side.

[0038] Specifically, as Figure 1 and Figure 2 shown, magnetic attraction blocks 11 are fixedly connected to the front side and the rear side of the opposite sides of the two storage boxes 2. The right side of the sliding cover 501 is magnetically attracted to the left side of the right magnetic attraction block 11.

[0039] In this embodiment: The first glass 502 is embedded in the sliding cover 501, facilitating the user to observe the tools in the storage box 2 from the top. The handle 503 facilitates the user to open and close the sliding cover 501. The sliding cover 501 is slidably connected between the opposite sides of two clamping blocks 10 on the right side. The clamping blocks 10 play a role in guiding and restricting the sliding of the sliding cover 501, enabling the sliding cover 501 to slide between the tops of the two storage boxes 2. One of the storage boxes 2 can be selected for sealing. When the sliding cover 501 moves to be magnetically attracted to the magnetic attraction block 11, the magnetic attraction block 11 can limit the sliding cover 501 to prevent accidental movement of the sliding cover 501.

[0040] Specifically, as Figure 2 and Figure 6 shown, a fixing column 9 is fixedly connected to the bottom of the magnetic attraction ball 4, and the bottom of the fixing column 9 is fixedly connected to the bottom of the inner wall of the storage box 2. Second glasses 6 are embedded on the opposite sides of the two storage boxes 2.

[0041] In this embodiment: Smaller metal tools and screws can be placed inside the storage box 2 and magnetically attracted by the magnetic attraction balls 4, further enhancing the fixing effect on the tools and screws and preventing the tools from falling when the ladder shakes or the user accidentally touches them.

[0042] Working principle: When the outrigger body 1 is in use, the storage box 2 provides a storage space for tools. When the user is working on an A-frame ladder, tools can be placed in the storage box 2 to prevent the tools from accidentally falling and causing danger. Small metal tools and screws can be placed inside the storage box 2 and magnetically attracted by the magnetic balls 4, further enhancing the fixing effect on the tools and screws and preventing the tools from falling when the ladder shakes or the user accidentally touches them. More commonly used tools can be inserted into the inner part of the limit box 303 for placement. At this time, the limit block 302 can be squeezed by the commonly used tools. By sliding the limit post 301 inside the through hole 7, the limit block 302 can be moved, and the spring 8 can be compressed. At this time, the elastic force of the spring 8 can squeeze the limit block 302 to clamp the commonly used tools, and the commonly used tools can be limited inside the limit box 303 to avoid accidental dropping of the tools and facilitate the taking and placing of the commonly used tools. By chamfering one side of the top of the limit block 302 close to the storage box 2, it is convenient to insert the commonly used tools into the limit box 303. When the tools are taken out of the storage box 2, the elastic force of the spring 8 will push the limit block 302 and the limit post 301 to reset, preparing for the next use. The first glass 502 is embedded in the sliding cover 501, facilitating the user to observe the tools in the storage box 2 from the top. The handle 503 facilitates the user to open and close the sliding cover 501. The sliding cover 501 is slidably connected between the opposite sides of the two right-side blocks 10. The blocks 10 play a role in guiding and restricting the sliding of the sliding cover 501, enabling the sliding cover 501 to slide between the tops of the two storage boxes 2. It is possible to choose to seal one of the storage boxes 2. By moving the sliding cover 501 to be magnetically attracted to the magnetic block 11, the magnetic block 11 can limit the sliding cover 501 to prevent accidental movement of the sliding cover 501. The tools in the storage box 2 can be observed from the side through the second glass 6. Through the coordinated action of the storage box 2, the magnetic balls 4, the limit block 302, and the sliding cover 501, effectively prevent the tools from falling off the A-frame ladder during use, improving the safety and convenience of working at heights, and avoiding the problem in the existing technical solutions that the tops of the left outrigger and the right outrigger do not have a structure for storing and limiting tools. When the worker climbs on the A-frame ladder and uses tools for work, when temporarily placing the tools, the tools are likely to accidentally fall, and it is necessary to return to the ground to pick them up, which is rather inconvenient. Moreover, the dropped tools are likely to injure the ground personnel, posing a safety hazard.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
