[0031] The following is combined with Figure 1-8 The utility model is further described in detail.
[0032] Example 1, refer to Figure 1-8 In order to solve the problem in the prior art that the herringbone ladder with fixed support by ropes can avoid the herringbone ladder opening angle of 180 degrees, it is difficult to ensure the instability caused by the two ladders being close to each other during use, and the problem that workers may take the wrong parts during residential construction, affecting the work progress.
[0033] The utility model discloses a multifunctional climbing device for residential construction, comprising: a top plate 1, on which a climbing ladder 1 2 and a climbing ladder 2 3 are rotatably mounted respectively; a mounting rod 6 is fixedly mounted on the opposite side of the climbing ladder 1 2 and the climbing ladder 2 3; a support rod 4 is rotatably mounted in the mounting rod 6; a same connecting block 7 is rotatably mounted on the opposite ends of the two support rods 4; two through holes 11 are provided in the connecting block 7; two through holes 13 connected to the corresponding through holes 11 are provided on both sides of the support rod 4; an insertion rod 8 is inserted and installed in the through hole 11; two ends of the insertion rod 8 respectively pass through the corresponding two through holes 2 13 and extend to the outside; a limiting hole 12 is provided at one end of the insertion rod 8; two limiting assemblies, which are respectively located in the two limiting holes 12 and are respectively used to limit the positions of the two insertion rods 8; a placement groove 17, which is provided at the top of the top plate 1, and a sealing plate 5 is rotatably mounted in the placement groove 17.
[0034] When the climbing ladder 1 2 and the climbing ladder 2 3 are folded up, the two limiting assemblies are used to respectively release the limits of the two insertion rods 8, and then the insertion rod 8 can be pulled out from the corresponding through-hole 1 1 and the corresponding two through-holes 2 13. After the two insertion rods 8 are removed, the limits between the connecting block 7 and the two support rods 4 are released. Subsequently, the climbing ladder 1 2 and the climbing ladder 2 3 can be brought close to each other. Under the action of gravity, the connecting block 7 will move downward, causing the opposite ends of the two support rods 4 to rotate downward until the climbing ladder 1 2 and the climbing ladder 2 3 contact each other. At this time, the two support rods 4 will also contact each other. Subsequently, the two insertion rods 8 can be restored to their original positions, and then the two limiting assemblies are used to respectively limit the positions of the two insertion rods 8, so that the opposite ends of the two support rods 4 cannot rotate, thereby fixing the positions of the climbing ladder 1 2 and the climbing ladder 2 3 and preventing them from being opened;
[0035] During use, when small parts such as screws are needed, the fixing assembly is used to release the fixing of the sealing plate 5. Then, the sealing plate 5 can be rotated and opened, and the staff can place the small parts in the placement groove 17, and then rotate and close the sealing plate 5. Then, the fixing assembly is used to fix the position of the sealing plate 5 to prevent the parts in the placement groove 17 from falling out. When taking small parts, it is more convenient to open the sealing plate 5 to take them.
[0036] The limiting block 10 is inserted and installed in the limiting hole 12. The limiting block 10 has a hand-tightening bolt 9 installed on its inner thread. One end of the hand-tightening bolt 9 passes through one side of the limiting hole 12 and extends to the outside.
[0037] By inserting the two limit blocks 10 into the two limit holes 12 respectively, and then rotating the two hand-tightening bolts 9, under the action of the thread, the hand-tightening bolts 9 will rotate and enter the limit blocks 10, thereby fixing the limit blocks 10 in the corresponding limit holes 12.
[0038] One end of the hand screw bolt 9 is threadedly connected to the insertion rod 8. Ensure that one end of the hand screw bolt 9 can be threadedly installed in the insertion rod 8.
[0039] The fixing assembly includes: a slide groove 14, which is opened in the top plate 1 and is located on one side of the placement groove 17. A slider 16 is slidably installed in the slide groove 14. One end of the slider 16 passes through one side of the slide groove 14 and extends into the sealing plate 5. A spring 15 is provided in the slide groove 14 and at the other end of the slider 16. The upper end of the slider 16 passes through the top of the slide groove 14 and extends to the outside.
[0040] By manually moving the slider 16, the slider 16 is displaced in the direction away from the sealing plate 5 until one end of the slider 16 is completely pulled out of the sealing plate 5. At this time, the spring 15 is squeezed by the slider 16 and will shrink. Then, the sealing plate 5 can be rotated and opened. The sealing plate 5 is rotated and closed. Under the action of the rebound force of the spring 15, the spring 15 will push the slider 16 and displace in the direction close to the sealing plate 5 until one end of the slider 16 is inserted into the sealing plate 5, thereby fixing the position of the sealing plate 5.
[0041] One end of the slider 16 is plugged into the sealing plate 5, and the two ends of the spring 15 are tightly welded to the other end of the slider 16 and the inner wall of the chute 14. Ensure that one end of the slider 16 can be inserted into the sealing plate 5 to ensure the structural stability of the spring 15.
[0042] The insertion rod 8 is plugged into the second through hole 13 to ensure that the insertion rod 8 can be inserted into the second through hole 13 .
[0043] The limiting hole 12 is located on one side of the support rod 4. Ensure that the limiting block 10 can limit the position of the insertion rod 8 after being inserted into the limiting hole 12.
[0044] The cross-sections of the through hole 11, the through hole 2, and the insertion rod 8 are all rectangular structures, ensuring that the insertion rod 8 will not rotate after being inserted into the through hole 11 and the through hole 2, 13.
[0045] Specific implementation principle: When stowing the climbing ladder 1 2 and the climbing ladder 2 3, the staff can turn the two hand-tightening bolts 9 by hand. Under the action of the thread, the hand-tightening bolt 9 will rotate and move, so that one end of the hand-tightening bolt 9 will move out of the limit block 10. At this time, the two limit blocks 10 will be released, and the staff can pull the limit block 10 upwards to make the limit block 10 be pulled out from the corresponding limit hole 12. At this time, the insertion rod 8 will be released, and then the insertion rod 8 can be pulled out from the corresponding through hole 11 and the corresponding two through holes 2 13. After the two insertion rods 8 are removed, the limit between the connecting block 7 and the two support rods 4 is released, and then the climbing ladder 1 2 can be raised. When the two ladders 1 and 2 are close to each other, the connecting block 7 will move downward under the action of gravity, causing the opposite ends of the two support rods 4 to rotate downward until the ladder 1 2 and the ladder 2 3 are in contact with each other. At this time, the two support rods 4 will also be in contact with each other. Subsequently, the two insertion rods 8 can be restored to their original positions, and then the two limit blocks 10 can be inserted into the two limit holes 12 respectively. Then, the two hand screws 9 are turned. Under the action of the threads, the hand screws 9 will rotate and enter the limit blocks 10, thereby fixing the limit blocks 10 in the corresponding limit holes 12, so that the opposite ends of the two support rods 4 cannot rotate, thereby fixing the positions of the ladder 1 2 and the ladder 2 3 and preventing them from being opened.
[0046] During use, when small parts such as screws are needed, the staff first moves the slider 16 to move the slider 16 in the direction away from the sealing plate 5 until one end of the slider 16 is completely pulled out of the sealing plate 5. At this time, the spring 15 will shrink due to the squeezing of the slider 16. Then, the sealing plate 5 can be rotated and opened. The staff can place the small parts in the placement groove 17, and then rotate and close the sealing plate 5. Under the action of the rebound force of the spring 15, the spring 15 will push the slider 16 to move in the direction close to the sealing plate 5 until one end of the slider 16 is inserted into the sealing plate 5, thereby fixing the position of the sealing plate 5 to prevent the parts in the placement groove 17 from falling out. When taking small parts, it is more convenient to open the sealing plate 5 to take them out.
[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
