Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a foldable scaffolding. Background Technology

[0002] Scaffolding refers to various supports erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It is commonly used in areas of construction sites where the exterior walls are too high for direct construction. Working platforms are one of the main components of scaffolding, primarily used by construction workers to stand on and perform their tasks. Scaffolding is classified according to its location as external or internal; according to materials as wooden, bamboo, or steel pipe; and according to its structural form as pole-type, bridge-type, frame-type, suspended, hanging, cantilevered, and climbing scaffolding.

[0003] Existing metal scaffolding is heavy and cannot be folded, making it inconvenient to quickly move and transport. Therefore, it does not meet the current needs. To address this, we propose a foldable scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable scaffolding to solve the problem mentioned in the background art that the existing metal scaffolding has a large self-weight and cannot be folded for use, which makes it inconvenient to quickly handle and transport the metal scaffolding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable scaffold, comprising two vertical support frames and a footrest crossbar. A footrest crossbar is installed at the upper end of the two vertical support frames. The two vertical support frames are symmetrically installed relative to the footrest crossbar. Each vertical support frame includes a first vertical rod, a third vertical rod is installed on one side of the first vertical rod, and a second vertical rod is installed on one side of the third vertical rod. A bending positioning unit is installed in the middle of the first, second, and third vertical rods. The bending positioning unit includes a positioning strip, a connecting frame is installed on one side of the positioning strip, and locking rods are installed on the inner sides of both the upper and lower ends of the connecting frame.

[0006] The footrest crossbar includes two overlapping plates, with multiple foot pedals installed between the two overlapping plates, and multiple transverse insertion units installed between the two overlapping plates and the multiple foot pedals. Each transverse insertion unit consists of a threaded sleeve and two connecting rods.

[0007] Preferably, the vertical support frame further includes a first connecting rod fixedly connected to the bottom end of the first vertical rod and the second vertical rod, a second connecting rod fixedly installed between the upper end of the first vertical rod and the second vertical rod, and the upper and lower ends of the third vertical rod being fixedly connected to the middle of the first connecting rod and the second connecting rod. The first vertical rod and the second vertical rod are installed symmetrically with respect to the third vertical rod.

[0008] Preferably, a plurality of climbing rods arranged in a linear pattern are installed between the first vertical rod and the third vertical rod. One end of each climbing rod passes through the first vertical rod and is inserted into the inside of the third vertical rod. The other end of each climbing rod is locked to the first vertical rod by a locking knob.

[0009] Preferably, the first, second, and third vertical rods are each composed of two rods, and adjacent rods are rotatably connected by a pin. The upper and lower ends of the connecting frame pass through the adjacent rods and are fixedly connected to the positioning strip by a locking rod.

[0010] Preferably, the two overlapping plates are in contact with the upper end face of the second connecting rod, the two ends of the threaded sleeve are provided with internal threads with opposite directions of rotation, the two ends of the threaded sleeve are connected to the two connecting rods by threads, and the ends of the two connecting rods away from the threaded sleeve are connected to the overlapping plates and the foot pedal by threads.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the first vertical rod and the second vertical rod are fixedly connected to the third vertical rod through the first connecting rod and the second connecting rod to form a vertical support frame. The first vertical rod, the second vertical rod and the third vertical rod are all kept vertically stable through bending positioning units, thereby realizing the stable support of the foot pedal cross frame by the vertical support frame. At the same time, the overlapping plate is connected to the foot pedal and the two adjacent foot pedals through the transverse insertion unit. By rotating the threaded sleeve, the threaded sleeve drives the two adjacent connecting rods to slide in opposite directions. Then, the threaded sleeve drives the two connecting rods to be inserted into the inner side of the overlapping plate and the end corner of the foot pedal, so as to realize the assembly of two overlapping plates and multiple foot pedals by multiple transverse insertion units.

[0013] 2. This utility model achieves the disassembly of the horizontal insertion unit from the overlapping plate and foot pedal by separating the connecting rod from the overlapping plate and foot pedal when the threaded sleeve is rotated in the opposite direction. This facilitates the folding and storage of the foot pedal cross frame. At the same time, the bending positioning unit in the middle of the first, second, and third vertical rods is disassembled, so that the positioning strip and connecting frame are separated from the locking rod. As a result, the two ends of the first, second, and third vertical rods swing relative to their middle parts, which facilitates the folding operation of the vertical support frame. This reduces the space occupied during scaffolding transportation and effectively improves the disassembly, assembly, and transportation of scaffolding. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1 The present invention provides an embodiment of a foldable scaffold, comprising two vertical support frames 1 and a footrest crossbar 2. A footrest crossbar 2 is installed at the upper end of the two vertical support frames 1. The two vertical support frames 1 are symmetrically installed with respect to the footrest crossbar 2. Each vertical support frame 1 includes a first vertical rod 104. A third vertical rod 106 is installed on one side of the first vertical rod 104. A plurality of linearly arranged climbing rods 103 are installed between the first vertical rod 104 and the third vertical rod 106. One end of the climbing rod 103 passes through the first vertical rod 104 and is inserted into the inner side of the third vertical rod 106. The other end of the climbing rod 103 is locked to the first vertical rod 104 by a locking knob 108. The multiple climbing rods 103 facilitate climbing by the user.

[0021] A second vertical rod 105 is installed on one side of the third vertical rod 106. A first connecting rod 101 is fixedly installed at the bottom of the first vertical rod 104 and the second vertical rod 105. A second connecting rod 102 is fixedly installed between the upper end of the first vertical rod 104 and the second vertical rod 105. The upper and lower ends of the third vertical rod 106 are fixedly connected to the middle of the first connecting rod 101 and the second connecting rod 102. The first vertical rod 104 and the second vertical rod 105 are symmetrically installed relative to the third vertical rod 106. The first connecting rod 101 and the second connecting rod 102 facilitate the stability of the first vertical rod 104, the second vertical rod 105 and the third vertical rod 106.

[0022] Please see Figures 1 to 3 A bending positioning unit 107 is installed in the middle of the first vertical rod 104, the second vertical rod 105, and the third vertical rod 106. The bending positioning unit 107 includes a positioning strip 109. A connecting frame 111 is installed on one side of the positioning strip 109. Locking rods 110 are installed on the inner sides of the upper and lower ends of the connecting frame 111. The first vertical rod 104, the second vertical rod 105, and the third vertical rod 106 are each composed of two rods. The two adjacent rods are rotatably connected by a pin. The upper and lower ends of the connecting frame 111 pass through the two adjacent rods and are fixedly connected to the positioning strip 109 by the locking rods 110. The bending positioning unit 107 is disassembled so that the positioning strip 109 and the connecting frame 111 are separated from the locking rods 110. Then, the two ends of the first vertical rod 104, the second vertical rod 105, and the third vertical rod 106 swing relative to their middle parts, which facilitates the folding operation of the vertical support frame 1.

[0023] Please see Figure 1 and Figure 4 The footrest frame 2 includes two overlapping plates 201, with multiple foot pedals 202 installed between the two overlapping plates 201. Multiple transverse insertion units 203 are installed between the two overlapping plates 201 and the multiple foot pedals 202. Each transverse insertion unit 203 consists of a threaded sleeve 204 and two connecting rods 205. The two overlapping plates 201 are in close contact with the upper end face of the second connecting rod 102. The two ends of the threaded sleeve 204 are provided with internal threads in opposite directions. The two ends of the threaded sleeve 204 are connected to the two connecting rods 205 by threads. The ends of the two connecting rods 205 away from the threaded sleeve 204 are connected to both the overlapping plates 201 and the foot pedals 202 by threads. By rotating the threaded sleeve 204 in the opposite direction, the connecting rods 205 are separated from the overlapping plates 201 and the foot pedals 202, thereby facilitating the folding and storage of the footrest frame 2.

[0024] In use, when installing and using the scaffolding, two vertical support frames 1 are assembled, and both ends of the footrest cross frame 2 are attached to the upper ends of the two vertical support frames 1. Specifically, the first vertical rod 104 and the second vertical rod 105 are fixedly connected to the third vertical rod 106 through the first connecting rod 101 and the second connecting rod 102 to form the vertical support frame 1. Then, one end of multiple climbing rods 103 is inserted through the first vertical rod 104 and inserted into the inside of the third vertical rod 106, so that the first vertical rod 104 and multiple climbing rods 103 are locked and installed through multiple locking knobs 108. The first vertical rod 104, the second vertical rod 105 and the third vertical rod 106 are all kept vertically stable through the bending positioning unit 107, thereby realizing the stable support of the footrest cross frame 2 by the vertical support frame 1.

[0025] Meanwhile, the overlapping plate 201 is connected to the foot pedal 202 and the two adjacent foot pedals 202 through the transverse insertion unit 203. By rotating the threaded sleeve 204, the threaded sleeve 204 drives the two adjacent connecting rods 205 to slide in opposite directions. Then, the threaded sleeve 204 drives the two connecting rods 205 to be inserted into the inner side of the end corner of the overlapping plate 201 and the foot pedal 202, so that the two overlapping plates 201 and the multiple foot pedals 202 can be assembled by the multiple transverse insertion units 203.

[0026] When the threaded sleeve 204 is rotated in the opposite direction, the connecting rod 205 is separated from the overlapping plate 201 and the foot pedal 202, thereby disassembling the horizontal connecting unit 203 from the overlapping plate 201 and the foot pedal 202. This facilitates the folding and storage of the footrest crossbar 2. At the same time, the bending positioning unit 107 in the middle of the first vertical bar 104, the second vertical bar 105 and the third vertical bar 106 is disassembled, so that the positioning strip 109 and the connecting frame 111 are separated from the locking rod 110. As a result, the two ends of the first vertical bar 104, the second vertical bar 105 and the third vertical bar 106 swing relative to their middle parts, which facilitates the folding operation of the vertical support frame 1 and effectively improves the disassembly, assembly and transportation of the scaffolding.

[0027] 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.
