[0039] Example

[0040] Please refer to Figure 1 and Figure 5 As shown, this embodiment provides a ladder stand stabilizer, comprising:

[0041] The overlapping portion 110 has a pair of overlapping legs 111;

[0042] The connecting portion 120 includes a fixed connecting portion 121 and a sliding connecting portion 122. The fixed connecting portion 121 includes a first crossbar 1211, a pair of first sleeves 1212 and a pair of first U-shaped clips 1213. The pair of first sleeves 1212 are respectively provided on both sides of the first crossbar 1211 to sleeve and fix the legs 111 and allow the lower ends of the legs 111 to pass through. One end of the pair of first U-shaped clips 1213 is connected to the first crossbar 1211. The sliding connection portion 122 includes a second cross bar 1221, a pair of second sleeves 1222 and a pair of second U-shaped clips 1223. The pair of second sleeves 1222 are respectively arranged on both sides of the second cross bar 1221 to slide and sleeve the lower end of the leg 111. One end of the pair of second U-shaped clips 1223 is connected to the second cross bar 1221, and the other end is hooped on another cross bar of the ladder body 200.

[0043] Specifically, the ladder stand stabilizer 100 is connected to the ladder body 200 through a connecting part 120. The connecting part 120 includes a fixed connecting part 121 and a sliding connecting part 122. The fixed connecting part 121 is connected to a certain cross bar of the ladder body 200, and its first sleeve 1212 is fixedly sleeved on the bridge leg 111 to ensure the stability of the connection structure; the sliding connecting part 122 is connected to another cross bar of the ladder body 200, and its second sleeve 1222 is slidably sleeved on the lower end of the bridge leg 111, and can be slidably adjusted to the distance with the fixed connecting part 121 to adapt to the distance between different cross bars of the ladder body 200, so that the ladder stand stabilizer 100 can meet the use requirements of different ladders, increase its universal applicability, and be easy to promote and use.

[0044] In addition, one end of a pair of first U-shaped clips 1213 is connected to the first crossbar 1211, and the other end is hooped to a crossbar of the ladder body 200, that is, a frame interface is formed between the closed end of the first U-shaped clip 1213 and the first crossbar 1211 to accommodate the crossbar of the ladder body 200, and the first crossbar 1211 is close to the crossbar of the ladder body 200 and connected to the first U-shaped clip 1213, so that the crossbar of the ladder body 200 is tightly fixed and connected within the frame interface; ensuring that the fixed connection part 121 is firmly connected to the ladder body 200 Fixed; one end of a pair of second U-shaped clips 1223 is connected to the second cross bar 1221, and the other end is hooped to another cross bar of the ladder body 200, that is, a frame interface that can accommodate the cross bar of the ladder body 200 is formed between the closed end of the second U-shaped clip 1223 and the second cross bar 1221, and the second cross bar 1221 is close to the cross bar of the ladder body 200 and connected to the first U-shaped clip 1213, so that the cross bar of the ladder body 200 is tightly fixedly connected to the frame interface, ensuring that the sliding connection part 122 is stably connected to the ladder body 200.

[0045] like Figure 1 、 Figure 3 and Figure 5 As shown, the closed end hoop of the first U-shaped clip 1213 is arranged on a certain crossbar of the ladder body 200, and the clamping foot of the first U-shaped clip 1213 faces the first crossbar 1211. The first crossbar 1211 is provided with a first latch hole 1214. The clamping feet on both sides of the first U-shaped clip 1213 are provided with a plurality of first through holes 1215 distributed in a straight line corresponding to the first latch holes 1214. The first latch hole 1214 and the first through hole 1215 are connected by a latch 123.

[0046] Specifically, a first pin hole 1214 is provided on the first cross bar 1211 and a plurality of corresponding first through holes 1215 are provided on the first U-shaped card 1213, and the pin 123 passes through the first pin hole 1214 and the first through hole 1215 to achieve a fixed connection between the ladder stand stabilizer 100 and the ladder body 200. While ensuring the stability of the connection, the cross bar width can be adjusted to adapt to different ladder bodies 200 by changing the position of the first through hole 1215 through which the pin 123 passes, thereby meeting the usage requirements of different ladder cross bar widths on the basis of meeting the usage requirements of different ladder cross bar spacings.

[0047] like Figure 3 and Figure 4 As shown, the first crossbar 1211 is provided with a first through slot 1217 for the foot of the first U-shaped card 1213 to pass through. The foot of the first U-shaped card 1213 passes through the first through slot 1217 and is fixedly connected to the first U-shaped card 1213 through the pin 123.

[0048] Furthermore, the width of the first through slot 1217 is greater than the width of the foot of the first U-shaped card 1213. There are several first pin holes 1214 along the width direction of the first through slot 1217. In order to adapt to the length of the cross bar of the ladder body 200 and achieve uniform force on the fixed positions of both ends of the cross bar of the ladder body 200, several first pin holes 1214 are set along the two ends of the ladder cross bar. The fixed position can be adjusted in this direction according to the different lengths of the cross bars of the ladder body 200. At the same time, in order to facilitate adjustment, the width of the first through slot 1217 is greater than the width of the foot of the first U-shaped card 1213, so that the foot of the first U-shaped card 1213 can also be adjusted to the fixed position after passing through the first through slot 1217.

[0049] like Figure 1 As shown, the leg 111 includes an upper leg 1111 and a lower leg 1112. The lower end of the upper leg 1111 is sleeved with the upper part of the lower leg 1112. The overlapping portion 110 of the upper leg 1111 and the lower leg 1112 is sleeved in the first sleeve 1212 and connected by a pin 123. Specifically, in order to facilitate carrying and placement, the ladder stand stabilizer 100 is of a detachable design. When idle, the ladder stand stabilizer 100 can be removed from the ladder body 200. When the leg 111 is disassembled, it can be decomposed into the upper leg 1111 and the lower leg 1112, which is convenient to carry and saves storage space.

[0050] Further, such as Figure 3 As shown, the latch 123 includes a pin body 1231 and an open spring strip 1232. One end of the open spring strip 1232 is connected to one end of the pin body 1231, and the other end is sleeved on the other end of the pin body 1231. The pin body 1231 and the open spring strip 1232 are fixed together to enhance their fixed stability.

[0051] like Figure 1 、 Figure 2 and Figure 5 As shown, a pair of legs 111 are distributed in a V-shape, and the two legs 111 expand outward to form an angle to further increase the stability of the overall structure.

[0052] Furthermore, the overlapping portion 110 also includes an extended leg 112, a pair of extended legs 112 are sleeved on the side of the leg 111 away from the ladder body 200, the leg 111 is provided with an extended pin hole 1113, and the extended leg 112 is provided with several extended through holes 1121 distributed at straight line intervals corresponding to the extended pin hole 1113.

[0053] Specifically, by providing an extended leg 112 at the overlapping portion 110 of the ladder stand stabilizer 100, it is possible to achieve horizontal length extension and contraction. While ensuring the stability and safety of the ladder, by adjusting the expanded leg 111, it is possible to overlap a climbing object that is laterally far away from the top of the ladder body 200 due to a large inclination angle.

[0054] like Figure 1 and Figure 5 As shown, the overlapping portion 110 also includes a workbench 113, which is arranged above the leg 111 and / or the extended leg 112, and a plurality of storage holes 1131 are provided on the workbench 113. By arranging the workbench 113 on the overlapping portion 110 and arranging a plurality of storage holes 1131 on the workbench 113, it is more convenient for users who need to place items to climb and use the ladder, thereby increasing the convenience of using the ladder. The position, shape and size of the storage holes 1131 can be adjusted according to the actual needs of the user, and are not further limited in this embodiment.

[0055] Furthermore, a pair of overlapping blocks 114 are provided at the end of the telescopic rod. The hardness of the material of the overlapping blocks 114 is lower than the hardness of the material of the object being overlapped, and the overlapping blocks 114 are detachably connected to the telescopic rod. Specifically, when the ladder is overlapped on the climbing body, the overlapping blocks 114 are in contact with the surface of the climbing body. On the one hand, its anti-slip ability is better than the edge of the ladder body 200 directly overlapping the climbing body, thereby improving stability and safety; on the other hand, the ladder body 200 does not contact the climbing body (such as a gutter, a wall panel, or a paint finish), thereby avoiding damage to the surface of the climbing body. The overlapping blocks 114 are detachably connected to the telescopic rod. If the overlapping blocks 114 are worn, they can be easily replaced. In this embodiment, the material of the overlapping blocks 114 is preferably rubber.

[0056] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
