[0022] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0023] like Figure 1-5 As shown, a building scaffold that is easy to use includes a sliding rod 1, a screw rod 2, a connecting frame 3 and a supporting frame 4; two connecting frames 3 are provided, and the two connecting frames 3 are spaced apart from each other, and the upper and lower ends of the sliding rod 1 and the screw rod 2 are respectively connected to the two connecting frames 3; the supporting frame 4 is slidably connected to the sliding rod 1, and a supporting gear 20 is screwed on the screw rod 2, and the supporting gear 20 is located below the supporting frame 4, and an adjusting gear 5 is rotatably provided on the supporting frame 4, and the adjusting gear 5 is located below the supporting frame 4, and the adjusting gear 5 and the supporting gear 20 are meshed with each other.

[0024] The connecting frame 3 is a frame-shaped structure. In this embodiment, two connecting frames are commonly provided, one is relatively located at the bottom, that is, one end close to the ground, and the other is located at the top; the two connecting frames 3 are respectively connected to the top and bottom of the sliding rod 1 and the screw rod 2 to ensure the stability of the sliding rod 1 and the screw rod 2.

[0025] The connecting frame 3 is provided with a sliding sleeve 10, which is respectively arranged above and below the connecting frame 3. When the connecting frame 3 is connected to the sliding rod 1, it slides through the connecting frame 3 and the sliding sleeve 10 is also provided to ensure the stability of the connecting frame 3 when it moves axially relative to the sliding rod 1.

[0026] A support gear 20 is threadedly connected to the screw rod 2, and the support gear 20 and the screw rod 2 are matched through a self-locking thread, that is, the support gear 20 can move relative to the screw rod 2 along the axial direction of the screw rod 2 only when it is rotated, thereby ensuring the safety and stability of the support frame 4.

[0027] The adjusting gear 5 is rotatably arranged on the connecting frame 3, and the adjusting gear 5 is meshed with the supporting gear 20. When the adjusting gear 5 is rotated, the supporting gear 20 rotates relative to the screw rod 2, thereby driving the entire connecting frame 3 to move axially relative to the sliding rod 1 (screw rod 2).

[0028] In some other embodiments, the radius of the adjusting gear 5 can be larger than the radius of the supporting gear 20, so that a fewer number of rotations of the adjusting gear 5 can cause a greater number of rotations of the supporting gear 20, thereby improving the efficiency of adjusting the height of the support frame 4.

[0029] Under the action of the adjusting gear 5, the supporting gear 20, the sliding rod 1 and the screw 2, the entire connecting frame 3 can be adjusted in the height direction. Compared with the scaffolding that cannot be adjusted in height as described in the background technology, the building scaffolding provided in the present application can be adjusted in height during use, thereby meeting the height requirements of the construction workers, which is very convenient.

[0030] In some further embodiments, two support frames 4 are provided, and the two support frames 4 are arranged at intervals; each support frame 4 corresponds to two sliding rods 1 and two screw rods 2.

[0031] Exemplarily, two support frames 4 are provided, and the two support frames 4 are arranged at an interval.

[0032] Each support frame 4 corresponds to two sliding rods 1 and two screw rods 2. Preferably, the two sliding rods 1 and the two screw rods 2 are arranged in a 2x2 square, which further ensures the operating stability and safety of the support frame 4.

[0033] When in use, construction workers can stand on one of the support frames 4 to adjust the height of the other support frame 4. After the adjustment is completed, they can move to the other support frame 4 and adjust one of the support frames 4 again, so that the workers do not need to get down from the scaffolding to adjust the height, which is very convenient.

[0034] In some further embodiments, the corresponding screw rods 2 in the two support frames 4 are arranged close to each other.

[0035] The screw rods 2 to which the two support frames 4 are attached are close to each other, so that the staff can adjust the adjustment gear 5 in the other support frame 4 on one of the support frames 4 .

[0036] In some further embodiments, a rotating handle is provided on the adjusting gear 5 , and the rotating handle is located on the upper side of the supporting frame 4 .

[0037] The adjusting gear 5 includes a rotating shaft 6 for realizing its rotation relative to the support frame 4, the lower end of the rotating shaft 6 is located below the support frame 4, and the upper end of the rotating shaft 6 is located above the support frame 4; the rotating handle includes a rotating handle 60 and a roller 61, one end of the rotating handle 60 is connected to the upper end of the rotating shaft 6, and the roller 61 is rotatably set at the other end of the rotating handle 60, the rotating handle 60 is set parallel to the support frame 4, and the roller 61 is set vertically to the support frame 4. During actual rotation, the construction personnel can rotate the roller 61 to drive the adjusting gear 5 to rotate, thereby rotating the supporting gear 20 and driving the support frame 4 to move up and down.

[0038] The weight of the support frame 4 is relatively moderate and should be as light as possible while ensuring the bearing capacity, so as to facilitate the height adjustment of the support frame 4 and ensure the flexibility of the entire scaffolding.

[0039] In some further embodiments, a sliding cavity is provided on the two sides of the two support frames 4 facing away from each other, a support plate 40 is slidably provided inside the sliding cavity, and a guardrail 41 is provided on the support plate 40 .

[0040] The support plate 40 can slide out of a part of the support frame 4 to temporarily increase the bearing area of ​​the entire support plate 40. It should be noted that the bearing capacity of the support plate 40 is relatively poor compared to the bearing capacity of the support frame 4. In actual use, it is preferred to place some construction tools used for the building.

[0041] A corresponding slide groove can be set at the bottom of the support plate 40, and a corresponding limiting protrusion can be set in the sliding cavity. When the support plate 40 slides to a certain extent, the limiting protrusion and the end of the slide groove are limited to prevent the support plate 40 from being pulled out excessively.

[0042] In some further embodiments, a rib 400 is provided at the bottom of the support plate 40, the length direction of the rib 400 is consistent with the sliding direction of the support plate 40, there are multiple ribs 400, and the multiple ribs 400 are arranged at intervals along the sliding direction of the vertical rib 400.

[0043] In order to further ensure the bearing capacity of the support plate 40, a plurality of ribs 400 are provided at the bottom of the support plate 40, thereby increasing the anti-bending capacity of the entire support plate 40 and ensuring the safety of its bearing.

[0044] In some further embodiments, an auxiliary plate 30 is slidably provided on the connecting frame 3 relatively located at the bottom, and the sliding direction of the auxiliary plate 30 is consistent with the sliding direction of the support plate 40; a bearing plate 31 is provided in the connecting frame 3 relatively located at the bottom to support the auxiliary plate 30 in a non-working state.

[0045] An auxiliary plate 30 is provided on the connecting frame 3 relatively to the bottom along the sliding direction of the supporting plate 40. When it is needed to be used, the construction personnel can first pull out the auxiliary plate 30 to increase the supporting performance of the entire scaffolding and reduce the risk of tipping.

[0046] When not in use, the auxiliary plate 30 can slide into the interior of the connecting frame 3. For this purpose, a bearing plate 31 is provided on the connecting frame 3 to support the auxiliary plate 30 in a non-working state.

[0047] In some further embodiments, universal wheels are provided on the bottom of the connecting frame 3 and the auxiliary plate 30 which are relatively located at the bottom.

[0048] The bottom of the connecting frame 3 and the bottom of the auxiliary plate 30 are both provided with locking universal wheels; it should be known that the universal wheels on the auxiliary plate 30 should be as close as possible to the outward edge of the auxiliary plate 30, and the bottoms of all the universal wheels should be in the same horizontal plane.

[0049] Universal wheels are relatively common in the industry and are prior art, and their specific structure and working principle will not be described in detail in this embodiment.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
