Technical Field

[0001] The utility model relates to the technical field of ladders, in particular to a ladder hanger. Background Art

[0002] A ladder is a widely used tool for climbing by leveraging force in daily life. Ladders on the market usually consist of two vertical rods and multiple crossbars fixed at equal intervals between the two vertical rods. When using a ladder to climb, the ladder needs to be leaned against a support obliquely. For example, the ladder can be leaned against the eaves, and the user climbs up by relying on the crossbars of the ladder.

[0054] Embodiment

[0055] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown in

[0056] Specifically, the left hanger 1 includes a first hanger 10 and a second hanger 11. The top of the first hanger 10 is provided with a hook-shaped first hanging part 101. By using the first hanging part 101 to contact the top of the support, the ladder 4 is leaned against the support. The bottom of the first hanger 10 is provided with a clamping part 102 that forms a bayonet with the first hanger 10. One end of the second hanger 11 is arranged at the bottom of the first hanger 10, and the other end of the second hanger 11 is provided with a hook part 111. The hook mouth of the hook part 111 is arranged facing the bayonet of the clamping part 102. Then, the two cross bars of the ladder 4 can be clamped by the clamping part 102 and the hook part 111, thereby realizing the connection between the left hanger 1 and the ladder 4. The top of the right hanger 2 is provided with a hook-shaped second hanging part 21 for contacting the support. A framing part 22 for framing the vertical bar of the ladder 4 is arranged on the middle part and / or the bottom of the right hanger 2. By framing the vertical bar of the ladder 4 with the framing part 22, the connection between the right hanger 2 and the ladder 4 is realized. In this way, the clamping part 102 and the hook part 111 clamp the two cross bars of the ladder 4, restricting the vertical displacement of the ladder 4, and the framing part 22 frames the vertical bar of the ladder 4, restricting the lateral displacement and deflection of the ladder 4, so that the ladder 4 can be placed stably, thereby ensuring safety during use.

[0057] Further, in order to reduce the possible damage to the support caused by the first hanging part 101 and the second hanging part 21 when contacting the support under the action of gravity, two overlapping parts 3 are provided. One overlapping part 3 is arranged on the hook end of the first hanging part 101, and the other overlapping part 3 is arranged on the hook end of the second hanging part 21. On the one hand, the overlapping part 3 can increase the contact area between the first hanging part 101 and the second hanging part 21 and the support, thereby increasing the friction force and improving the stability of the ladder 4; on the other hand, the overlapping part 3 can be made of a flexible material to improve the adhesion to the support and prevent the first hanging part 101 and the second hanging part 21 from damaging the support.

[0058] In this way, the structure of the ladder hanger is simple, and the disassembly and assembly with the ladder 4 are convenient. Since the left hanger 1 is connected to the cross bar on one side of the ladder 4 and the right hanger 2 is connected to the vertical bar on the other side of the ladder 4, the distance between the left hanger 1 and the right hanger 2 can also be adjusted to adapt to the vertical bar distances of different ladders 4, expanding the applicable range of the ladder hanger.

[0059] As Figure 3 、 Figure 4 、 Figure 6 and Figure 7 shown, in this embodiment, one overlapping part 3 includes an overlapping rod 31 and two anti-slip rubber sleeves 32. The overlapping rod 31 is welded to a plate-shaped part to form a "T" shape, and then bolted to the hook end of the first hanging part 101 and distributed in a "T" shape. One anti-slip rubber sleeve 32 is arranged at one end of the overlapping rod 31, and the other anti-slip rubber sleeve 32 is arranged at the other end of the overlapping rod 31. And the other overlapping part 3 is arranged on the hook end of the second hanging part 21 with the same structure as one overlapping part 3.

[0060] Specifically, the overlapping part 3 is used to increase the contact area between the first hanging part 101 and the second hanging part 21 and the support, thereby increasing the friction force between the first hanging part 101 and the second hanging part 21 and the support, so that the ladder 4 can be placed more stably. The anti-slip rubber sleeves 32 sleeved at both ends of the overlapping rod 31 can improve the adhesion of the overlapping part 3 to the support, further improve the stability of the placement of the ladder 4, and avoid damaging the support at the same time.

[0061] As Figure 4 and Figure 5 shown, in this embodiment, a channel-shaped part is welded to the bottom of the first hanger 10 to form a fixed box. A fixing hole 103 is arranged in the fixed box. A plurality of adjusting holes 112 are arranged along the length direction of the top of the second hanger 11. An installation hole 1022 is arranged on the clamping part 102. The top of the second hanger is inserted into the fixed box, and the fixing bolt 1023 passes through the installation hole 1022, the fixing hole 103 and the adjusting hole 112 and then is locked.

[0062] Specifically, since the spacing between the crossbars of different ladders 4 is different, by selecting adjustment holes 112 at different positions and aligning the positions of the adjustment holes 112, the fixing holes 103, and the mounting holes 1022, the connection of the first hanger 10, the second hanger 11, and the clamping member 102 can be realized by using the fixing bolt 1023. In this way, by selecting adjustment holes 112 at different positions, the connection position of the first hanger 10 and the second hanger 11 can be adjusted, and further the spacing between the clamping member 102 and the hook member 111 can be adjusted to adapt to the crossbar spacing of different ladders 4, expanding the applicable range of the ladder 4 hanger.

[0063] As Figure 4 and Figure 5 shown, in this embodiment, the clamping member 102 is a Z-shaped structure. The mounting hole 1022 is arranged on a cross plate of the Z-shaped structure, and a clamping opening for clamping the crossbar of the ladder 4 is formed between another cross plate of the Z-shaped structure and the first hanger 10. Since the mounting hole 1022 is a strip-shaped hole, the mounting position of the clamping member 102 can be adjusted through the strip-shaped hole. Opposite toothed grooves 10221 are arranged on both side walls of the mounting hole 1022, and the toothed grooves 10221 can be engaged and fixed, so that the fixing bolt 1023 is not easy to rotate, achieving an anti-loosening effect.

[0064] Furthermore, in order to strengthen the connection strength between the left hanger 1 and the ladder 4, a limiting plate 104 and a limiting bolt 1041 that abuts against or separates from a cross plate of the Z-shaped structure are arranged on the first hanger 10. The limiting bolt 1041 is threadedly penetrated through the limiting plate 104. By rotating the limiting bolt 1041, the tightening force of the limiting bolt 1041 against the clamping member 102 can be adjusted, and further the clamping force of the clamping member 102 and the hook member 111 for clamping the crossbar of the ladder 4 can be strengthened.

[0065] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in this embodiment, a fixing band 12 for connecting with the vertical rod is arranged in the middle of the left hanger 1.

[0066] As Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in this embodiment, the frame connector 22 includes a first frame connector 221 and a second frame connector 222. The first frame connector 221 is disposed in the middle of the right hanger 2, and the second frame connector 222 is disposed at the bottom of the right hanger 2. By respectively disposing the first frame connector 221 and the second frame connector 222 in the middle and at the bottom of the right hanger 2, the connection strength between the right hanger 2 and the ladder 4 is improved.

[0067] As Figure 6 and Figure 7 shown, in this embodiment, the first frame connector 221 includes a first connecting plate 2211, a second connecting plate 2212, and a plurality of first connecting members 2213 connecting the first connecting plate 2211 and the second connecting plate 2212. Specifically, the first connecting plate 2211 is attached to the side of the right hanger 2 facing away from the ladder 4, and the second connecting plate 2212 is attached to the side of the vertical rod of the ladder 4 facing away from the right hanger 2. The first connecting plate 2211 and the second connecting plate 2212 are connected by the first connecting members 2213 to frame the vertical rod of the ladder 4. The first connecting members 2213 can be butterfly bolts, which can be disassembled and assembled by hand rotation.

[0068] Moreover, a plurality of first connecting holes 22111 are provided in the first connecting plate 2211 along the width direction, and a plurality of second connecting holes 22121 corresponding to the first connecting holes 22111 are provided in the second connecting plate 2212.
