[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0020] Example
[0021] The present embodiment provides a stepladder that is convenient for placing tools, such as Figure 1 and Figure 3As shown, the ladder body 1 is a "herringbone ladder" structure, which can also be called "herringbone ladder" or "A-type ladder". The ladder body 1 is mainly composed of four ladder beams, a plurality of pedals and ladder feet. Because the ladder body 1 is a relatively mature technology known in the art, its specific structure and principle are well known to those skilled in the art, so it will not be repeated. When in use, workers can perform construction on the high roof by stepping on the pedals.
[0022] like Figure 1 As shown, a groove is provided at the top of the left front ladder beam of the ladder body 1, and a plug rod 6 is vertically arranged in the groove; when the plug rod 6 is arranged in the groove, it can move up and down in the vertical direction in the groove;
[0023] like Figure 1 As shown, a limit block 7 is arranged in the groove, and the limit block 7 is fixed on the inner side of the notch of the groove. A second threaded hole communicating with each other from top to bottom is provided on the limit block 7, and a first external thread threadedly matched with the second threaded hole is provided on the lower end of the insertion rod 6; the outer diameter of the insertion rod 6 is smaller than the major diameter of its first external threaded section; this section of the scheme as a whole constitutes a locking assembly for locking the lower end of the insertion rod 6 in the notch of the groove; because the outer diameter of the insertion rod 6 is smaller than the major diameter of the threaded section on it, the part without thread on the insertion rod 6 can pass through the threaded hole on the limit block 7; because the insertion rod 6 can move up and down in the groove, so the upper end of the insertion rod 6 can pass through the threaded hole on the limit block 7. When the lower end of the insertion rod 6 moves to the position of the threaded hole, the external thread at the lower end of the insertion rod 6 can be tightened on the threaded hole of the limit block 7, thereby locking the lower end of the insertion rod 6; by tightly limiting only the lower end of the insertion rod 6, when the insertion rod 6 needs to be used, it is pulled out of the groove and fixed; when the insertion rod 6 needs to be stored, the insertion rod 6 is moved back into the groove, thereby saving a certain amount of storage space;
[0024] In the specific implementation process, the limit block 7 in the locking assembly can also be replaced by a screw, and the groove and the insertion rod 6 are both provided with interconnected screw holes, and the rear screw is passed through the two screw holes, thereby fixing the insertion rod 6 in the groove;
[0025] like Figure 1 and Figure 2 As shown, a connecting rod 5 is horizontally arranged on the left side of the upper end of the insertion rod 6, and the right end of the connecting rod 5 is fixed on the insertion rod 6. A sliding sleeve 10 capable of free rotation is sleeved on the connecting rod 5. When the sliding sleeve 10 is specifically installed on the connecting rod 5, it is directly inserted on the connecting rod 5, so that the sliding sleeve 10 can realize free rotation;
[0026] like Figure 1As shown, a first storage box 2 for storing tools is fixed on the outer wall of the sliding sleeve 10; because the first storage box 2 is fixed on the sliding sleeve 10, the sliding sleeve 10 can rotate on the connecting rod 5, so it can drive the first storage box 2 to rotate. Therefore, when in use, when the ladder body 1 is opened, the insertion rod 6 and the connecting rod 5 will also tilt with the ladder body 1, so that the first storage box 2 will also tilt, and then the first storage box 2 can be rotated on the connecting rod 5 through the sliding sleeve 10, so that the first storage box 2 can be adjusted to a horizontal state, and it is convenient for workers to place the tools to be used on the first storage box 2 later. The design of storing tools in the first storage box 2 avoids the problem of inconvenient tools to be taken during use.
[0027] like Figure 1 and Figure 2 As shown, a first threaded hole communicating with the inside and outside is provided on the sliding sleeve 10, and a fastening screw 9 threadably matched with the first threaded hole is installed in the first threaded hole; through the design of the fastening screw 9, when the sliding sleeve 10 drives the first storage box 2 to rotate to a horizontal position, the position of the sliding sleeve 10 can be fixed by tightening the fastening screw 9, thereby limiting the first storage box 2 to prevent it from continuing to rotate under the action of the sliding sleeve 10, so that the tool can be stably placed in the first storage box 2;
[0028] like Figure 1 and Figure 2 As shown, the fastening screw 9 is in a "T"-shaped structure. With the design of this structure, it is more convenient and quick to rotate the fastening screw 9;
[0029] like Figure 1 and Figure 2 As shown, the connecting rod 5 is provided with an anti-slip sleeve 8 to prevent the sliding sleeve 10 from moving out from its left end, the left end of the connecting rod 5 is provided with a second external thread, and the inner side wall of the anti-slip sleeve 8 is provided with an internal thread that is threadably matched with the second external thread; when the anti-slip sleeve 8 specifically prevents the sliding sleeve 10 from moving out, the inner diameter of the sliding sleeve 10 is smaller than the outer diameter of the anti-slip sleeve 8, so the anti-slip sleeve 8 can limit the sliding sleeve 10; when the anti-slip sleeve 8 is specifically installed, the internal thread on it is directly tightened on the external thread of the connecting rod 5 to complete the installation; when the anti-slip sleeve 8 is unscrewed from the connecting rod 5, the sliding sleeve 10 can drive the first storage box 2 to be taken out together, thereby facilitating the disassembly and replacement of the first storage box 2;
[0030] like Figure 1 , Figure 3 and Figure 4As shown, a second storage box 3 is arranged on the left side of the first storage box 2, and a slide groove for the second storage box 3 to slide left and right is opened on the left side wall of the first storage box 2, and the second storage box 3 and the slide groove are slidably matched with each other left and right; through this design, when a large number of tools are used, the second storage box 3 can be pulled out of the slide groove, and then the excess tools can be placed in the second storage box 3, so that more tools can be stored through the design of two storage boxes;
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, a handle 4 is fixed on the second storage box 3 for conveniently pulling it to slide left and right in the slide slot. The design of the handle 4 makes it more convenient to pull the second storage box 3 to move left and right.
[0032] The first storage box 2 and the second storage box 3 are both made of aluminum. Aluminum has many advantages, such as being lightweight and high-strength, lighter than other metal materials, corrosion-resistant, excellent in thermal conductivity, and good in machinability.
[0033] During specific use: when using the ladder body 1, first pull the upper end of the insertion rod 6 out of the groove, and when its lower end is pulled to the position of the groove notch, rotate the insertion rod 6 to lock the lower end in the groove; then adjust the first storage box 2 to a horizontal state, and then tighten and fix it by fastening the screws 9; then place the required tools in the first storage box 2, and then take the tools out of the first storage box 2 for use; when use is completed, the used tools can be taken out of the first storage box 2, and the insertion rod 6 can be re-stored in the groove, avoiding the problem of occupying a large space when storing; during use, through the design of the first storage box 2, the tools can be placed, so that it is convenient for workers to directly take out and replace tools.
