[0032] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figure 1-Figure 6 The folding drawer-type platform disclosed in the utility model includes a platform body 1, a diagonal support 3 and an extended drawer frame 5, wherein the extended drawer frame 5 is stored in a folding frame 4 and can be effectively unfolded outward when in use, thereby expanding the activity space of construction workers. The technical solution is specifically described as follows:

[0034] In a specific embodiment disclosed in the present utility model, Figure 1 and Figure 2 The platform body 1 is a lattice structure, counterweights can be added to the bottom, and a load-bearing member 2 is installed on the top. The platform body 1 is equipped with a load-bearing member 2 on the top, and a folding frame 4 is hingedly installed at the edge of the load-bearing member 2. The folding frame 4 can swing up and down. When placed vertically, the folding frame 4 can be used as a guardrail. When placed horizontally, it can be stepped on by users, thus serving as a pressure plate extending outward. For the convenience of description, spatial relative terms can be used here to describe, for example, Figure 1The spatial positional relationship of one device or feature shown in the figure to other devices or features. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

[0035] In this embodiment, structurally, the end of the folding frame 4 is hinged to the load-bearing component 2, and the side of the folding frame 4 can be abutted against the diagonal brace 3, and the other end of the diagonal brace 3 is hinged to the front side of the platform body 1, thereby using the diagonal brace 3 as a load-bearing component to keep the folding frame 4 level.

[0036] On the basis of this structure, an extended drawer frame 5 is also slidably arranged at the bottom of the folding frame 4, and the extended drawer frame 5 can slide along the folding frame 4. Specifically, the platform body 1, the load-bearing member 2, the diagonal support 3, the folding frame 4 and the extended drawer frame 5 are all sprayed with anti-rust paint. The folding frame 4 is provided with a plurality of linearly arranged positioning holes 6, and the extended drawer frame 5 is provided with a limiting hole 8, and any positioning hole 6 is suitable for being aligned with the limiting hole 8 and fixed by a pin.

[0037] In some embodiments, Figure 5 and Figure 6 The diagonal brace 3 includes a telescopic rod 31 and a block 33. Two mounting seats 32 are provided at both ends of the telescopic rod 31. The mounting seats 32 are provided with plug holes. One of the mounting seats 32 is suitable for being installed on the double-ear plate seat 7 on the front side of the platform body 1. The plug hole is fixed to the slot of the double-ear plate seat 7 through a pin shaft. The other mounting seat 32 abuts against the block 33 provided at the bottom of the folding frame 4 and is locked with a fastener, thereby fixing the position of the folding frame 4.

[0038] In some embodiments, the folding frame 4 includes a guide rail frame 41 and a load-bearing mesh surface 42, and the load-bearing mesh surface 42 is also sprayed with anti-rust paint, welded and covered on the guide rail frame 41. A block 33 is installed at the bottom of the guide rail frame 41. At the same time, a number of positioning holes 6 are evenly arranged along the length direction of the guide rail frame 41, so that the positioning holes 6 can be aligned with the limit holes 8 and fixed by fasteners while adjusting the extension length of the drawer frame 5. It should be noted that the detailed description of this embodiment is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as those generally understood by ordinary technicians in the technical field to which this application belongs.

[0039] In some embodiments, Figure 4The extended drawer rack 5 includes a frame 51 and a steel mesh 52. The limiting holes 8 are arranged on the frame 51. The frame 51 is covered with the steel mesh 52. In another optional technical solution, a guide groove 53 is also arranged on the top of the frame 51. A guide frame 41 is slidably arranged in the guide groove 53. The guide groove 53 is a closed slide groove. The guide frame 41 can only slide in the guide groove 53, and the block 33 is fixedly installed at the bottom of the frame 51. In the case that the length of the telescopic rod 31 is inconvenient, when the folding rack 4 is folded upward, the frame 51 is also automatically folded into the folding rack 4 under the traction of the telescopic rod 31. Similarly, when the folding rack 4 is squared downward, the extended drawer rack 5 can also be automatically unfolded.

[0040] In this embodiment, the telescopic rod 31 may be a cylinder or a motor screw structure, so as to achieve the effect of automatically adjusting the length of the telescopic rod 31 .
