Description

Technical Field

[0001] This utility model relates to the field of building engineering and construction technology, and in particular to a height-adjustable construction operation stool. Background Technology

[0002] In construction scenarios such as building decoration and equipment installation, construction workers often need to use work stools as climbing tools when performing low-altitude operations such as ceiling painting, lighting installation, and pipeline laying. To adapt to different working heights, existing technology often designs the legs of the work stools as telescopic rod structures. The height can be changed by adjusting and locking the telescopic joints. This type of structure is particularly common in interior building applications.

[0003] However, while pursuing height adjustment, these telescopic work stools often neglect their suitability for confined spaces. Especially in residential areas with limited space, such as staircases and corners, poorly designed work stools can take up too much space, making it easy for construction workers to bump into walls while carrying them up and down stairs or moving them. This inconvenience not only affects construction efficiency but also poses a significant safety hazard, increasing the risk of workers losing their balance and falling.

[0004] To address the above technical problems, this utility model discloses a height-adjustable construction operating stool. This utility model has advantages such as improving the stability of the connection by reducing the height of the operating stool while using the removed ladder mechanism, and reducing the horizontal and vertical space occupied by the device by folding the top plate and reducing the height of the operating stool. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a height-adjustable construction operating stool. This utility model improves the stability of the connection by reducing the height of the operating stool and using the removed ladder mechanism. At the same time, it reduces the horizontal and vertical space occupied by the device by folding the top plate and reducing the height of the operating stool.

[0006] This utility model is achieved through the following technical solution: This utility model discloses a height-adjustable construction operation stool, including a top plate 1 and a top plate 2 connected at their tops by a hinge shaft. A climbing mechanism 1, a climbing mechanism 2, and a climbing mechanism 3 are sequentially connected from high to low at the outer bottom ends of the top plates 1 and 2. The outer bottom ends of the top plates 1 and 2 are hinged to the climbing mechanism 1. The bottom of both the top plates 1 and 2 are provided with support mechanisms to maintain stability. The bottom ends of the climbing mechanisms 1 and 2 are symmetrically provided with limit grooves, and springs are fixed to the inner ends of the limit grooves. A slider is connected to the other end of the spring, and plug-in blocks are symmetrically fixed to the outer ends of the sliders. An elastic rope is provided between the two plug-in blocks. The top ends of the climbing mechanisms 2 and 3 are symmetrically provided with embedding blocks that can be inserted into the limit grooves. An insertion groove is provided at the top of the embedding block for the plug-in block to be inserted into, and the other end of the elastic rope is connected to the top of the embedding block.

[0007] Furthermore, connecting grooves are provided on the climbing mechanism 1 and climbing mechanism 2 at the position of the limiting groove.

[0008] Furthermore, climbing mechanism one, climbing mechanism two, and climbing mechanism three are all distributed in an I-shape, and each climbing mechanism three has a support leg hinged at its bottom.

[0009] Furthermore, at the hinge position between top plate one and top plate two and climbing mechanism one, a limiting plate is fixed to the outside of climbing mechanism one to abut against the sides of top plate one and top plate two.

[0010] Furthermore, the support mechanism includes two fixed seats fixedly connected to the inner side of the climbing mechanism, and a sliding groove is provided on the inner side of the fixed seats. An abutment block is slidably connected inside the sliding groove, and an abutment groove for limiting the abutment block is provided at the top of the sliding groove. A hinge plate is hinged on the abutment groove, and grooves are symmetrically provided at the bottom ends of the top plate 1 and the top plate 2. A hinge rod is fixed at the end of the groove away from the climbing mechanism 1, and the other end of the hinge plate is sleeved on the hinge rod.

[0011] Furthermore, the connecting groove on the first climbing mechanism is connected to the limiting groove on one side, while the connecting groove on the second climbing mechanism is connected to the limiting groove on both sides.

[0012] This utility model has the following advantages:

[0013] (1) This utility model selects one of the climbing mechanisms 2 and moves the embedded block at its top out of the corresponding limiting groove, so that the plug-in block and the plug-in groove are released from the limiting state, thereby removing the selected climbing mechanism 2 at its original height. During this process, due to the presence of the elastic rope, when the selected climbing mechanism 2 is removed, the elastic rope can slide along the connecting groove above the selected climbing mechanism 2, thereby attaching the selected climbing mechanism 2 to the outside of the climbing mechanism below it. Then, the climbing mechanism below the selected climbing mechanism 2 is inserted into the top of the selected climbing mechanism 2, thereby reducing the height of the top plate 1 and the top plate 2. The removed climbing mechanism 2 will attach between the climbing mechanism 3 and the upper climbing mechanism 2, thereby increasing the stability of the connection between the upper climbing mechanism 2 and the climbing mechanism 3.

[0014] (2) On the one hand, this utility model removes the contact block from inside the contact groove and then lets the contact block slide down the groove to its bottom. Since the top plate one and the top plate two are hinged by the hinge shaft, and the top plate one and the top plate two are hinged to the climbing mechanism one, the top plate one and the top plate two will fold inward, thereby reducing the horizontal space occupied by the device. On the other hand, by reducing the height between the top plate one and the top plate two, the climbing mechanism one, the climbing mechanism two and the climbing mechanism three can cooperate with each other, thereby reducing the vertical space occupied by the device.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model, and detailed implementation methods and specific operation processes are given. However, the protection scope of this utility model is not limited to the following embodiments. In the description of this utility model, words such as "front", "rear", "left", and "right" that indicate orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The embodiment discloses a height-adjustable construction operation stool, such as Figure 1 -- Figure 5 As shown, the device includes a top plate 100 and a top plate 200 connected at their tops by a hinge shaft 300. A climbing mechanism 400, a climbing mechanism 500, and a climbing mechanism 600 are connected sequentially from high to low at the bottom outer sides of the top plate 100 and the top plate 200. The bottom outer sides of the top plate 100 and the top plate 200 are hinged to the climbing mechanism 400. The bottom of the top plate 100 and the top plate 200 are both provided with a support mechanism for maintaining the stability of the top plate 100 and the top plate 200.

[0023] like Figures 1-4 As shown, both the first climbing mechanism 400 and the second climbing mechanism 500 have symmetrically provided limiting grooves 403 at their bottom ends, and a spring 404 is fixed to the inner end of the limiting groove 403. The other end of the spring 404 is connected to a slider 405, and the outer end of the slider 405 is symmetrically fixed with a plug-in block 406. An elastic rope 407 is provided between the two plug-in blocks 406. The top ends of the second climbing mechanism 500 and the third climbing mechanism 600 are symmetrically fixed with an embedded block 501 that can be inserted into the limiting groove 403. A plug-in groove 502 is provided at the top end of the embedded block 501 for the plug-in block 406 to be inserted, and the other end of the elastic rope 407 is connected to the top end of the embedded block 501. A connecting groove 402 is provided on the first climbing mechanism 400 and the second climbing mechanism 500 at the position of the limiting groove 403.

[0024] When it is necessary to lower the height of top plate 100 and top plate 200, firstly, select one of the climbing mechanisms 2 500 and move its top embedded block 501 out of the corresponding limiting groove 403, so that the plug block 406 is released from the limiting state of the plug groove 502, thereby removing the selected climbing mechanism 2 500 at its original height; during this process, due to the presence of the elastic rope 407, when removing the selected climbing mechanism 2 500, the elastic rope 407 can slide along the connecting groove 402 above the selected climbing mechanism 2 500, thereby fitting the selected climbing mechanism 2 500 against the outside of the climbing mechanism below it. Then, insert the climbing mechanism below the selected climbing mechanism 2 500 into the top of the selected climbing mechanism 2 500, thereby lowering the height of top plate 100 and top plate 200.

[0025] For example, such as Figure 2 As shown, when the second climbing mechanism 500 above the third climbing mechanism 600 is removed, the elastic rope 407 connecting the upper and lower second climbing mechanisms 500 will slide upward along the connecting groove 402 on the upper second climbing mechanism 500. At the same time, the limiting groove 403 at the bottom of the lower second climbing mechanism 500 will also disengage from the top embedded block 501 of the third climbing mechanism 600. Since the connecting groove 402 on the second climbing mechanism 500 is double-sided, the elastic rope on the lower second climbing mechanism 500 will... 407 will slide along the inner side of the connecting groove 402 opened at the lower rear, and then insert the embedded block 501 on the climbing mechanism 3 600 into the limiting groove 403 of the upper climbing mechanism 2 500 to limit it, thereby achieving the effect of reducing the height of the top plate 1 100 and the top plate 2 200. At the same time, the removed climbing mechanism 2 500 will fit between the climbing mechanism 3 600 and the upper climbing mechanism 2 500, thereby increasing the stability of the connection between the upper climbing mechanism 2 500 and the climbing mechanism 3 600.

[0026] In this embodiment, the climbing mechanism 1 400, climbing mechanism 2 500 and climbing mechanism 3 600 are all arranged in an I-shape, and each climbing mechanism 3 600 has a support foot 601 hinged to its bottom end.

[0027] like Figure 4 As shown, in this embodiment, a limiting plate 401 is fixed to the outside of the climbing mechanism 400 at the hinge position between the top plate 100 and the top plate 200 and the climbing mechanism 400. The limiting plate 401 is designed to prevent the top plate 100 and the top plate 200 from rotating outward along the hinge position of the climbing mechanism 400.

[0028] like Figure 3As shown, in this embodiment, the support mechanism includes two fixed seats 411 fixedly connected to the inner side of the climbing mechanism 400. A sliding groove 410 is provided on the inner side of the fixed seat 411, and an abutment block 409 is slidably connected inside the sliding groove 410. An abutment groove 408 for limiting the abutment block 409 is provided at the top of the sliding groove 410. A hinge plate 412 is hinged to the abutment groove 408. Grooves 101 are symmetrically provided at the bottom ends of the top plate 100 and the top plate 200, and the grooves 101 are far away from the climbing mechanism 400. One end of the hinge is fixed with a hinge rod 102, and the other end of the hinge plate 412 is sleeved on the hinge rod 102. By moving the abutment block 409 out of the abutment groove 408, the abutment block 409 slides down the slide groove 410 to its bottom. Since the top plate 100 and the top plate 200 are hinged through the hinge shaft 300, and the top plate 100 and the top plate 200 are hinged to the climbing mechanism 400, the top plate 100 and the top plate 200 will fold inward, thereby reducing the lateral space occupied by the device.

[0029] In this embodiment, the connecting groove 402 on the first climbing mechanism 400 is connected to the limiting groove 403 on one side, while the connecting groove 402 on the second climbing mechanism 500 is connected to the limiting groove 403 on both sides. Since the connecting groove 402 on the second climbing mechanism 500 is connected on both sides, the elastic rope 407 on the lower second climbing mechanism 500 will slide along the inner side of the connecting groove 402 on the lower rear side.

[0030] In this embodiment, during operation: First, workers use the ladder mechanism 1 (400), ladder mechanism 2 (500), and ladder mechanism 3 (600) to work on top plate 1 (100) and top plate 2 (200). When it is necessary to lower the height of top plate 1 (100) and top plate 2 (200), one of the ladder mechanisms 2 (500) is selected, and its top embedded block 501 is moved out of the corresponding limiting groove 403, so that the insertion block 406 is released from the limiting state with the insertion groove 502, thereby raising the selected ladder mechanism 2 (500) to its original height. During the removal process, due to the presence of the elastic rope 407, when removing the selected climbing mechanism 2 500, the elastic rope 407 can slide along the connecting groove 402 above the selected climbing mechanism 2 500, thereby fitting the selected climbing mechanism 2 500 against the outside of the climbing mechanism below it. Then, the climbing mechanism below the selected climbing mechanism 2 500 is inserted above the selected climbing mechanism 2 500, thereby reducing the height of the top plate 1 100 and the top plate 2 200. For example, as... Figure 2As shown, when the second climbing mechanism 500 above the third climbing mechanism 600 is removed, the elastic rope 407 connecting the upper and lower second climbing mechanisms 500 will slide upward along the connecting groove 402 on the upper second climbing mechanism 500. At the same time, the limiting groove 403 at the bottom of the lower second climbing mechanism 500 will also disengage from the top embedded block 501 of the third climbing mechanism 600. Since the connecting groove 402 on the second climbing mechanism 500 is double-sided, the elastic rope on the lower second climbing mechanism 500 will... 407 will slide along the inner side of the connecting groove 402 opened at the rear below, and then insert the embedded block 501 on the climbing mechanism 3 600 into the limiting groove 403 of the upper climbing mechanism 2 500 to limit it, thereby achieving the effect of reducing the height of the top plate 1 100 and the top plate 2 200. At the same time, the removed climbing mechanism 2 500 will fit between the climbing mechanism 3 600 and the upper climbing mechanism 2 500, thereby increasing the stability of the connection between the upper climbing mechanism 2 500 and the climbing mechanism 3 600.

[0031] Meanwhile, when the device is stored as a whole, on the one hand, the contact block 409 is removed from the inside of the contact groove 408, and then the contact block 409 slides down the slide groove 410 to its bottom. Since the top plate 100 and the top plate 200 are hinged through the hinge shaft 300, and the top plate 100 and the top plate 200 are hinged to the climbing mechanism 400, the top plate 100 and the top plate 200 will fold inward, thereby reducing the horizontal space occupied by the device. On the other hand, by reducing the height between the top plate 100 and the top plate 200, the climbing mechanism 400, the climbing mechanism 2 500 and the climbing mechanism 3 600 can cooperate with each other, thereby reducing the vertical space occupied by the device.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
