Description

Technical Field

[0001] This utility model relates to the field of building structure testing technology, and in particular to a drawing device. Background Technology

[0002] Currently, before demolishing a building, it is necessary to understand the building's structural layout and stress conditions, and to develop a demolition plan using the building's design drawings. However, for some buildings that have been in use for a long time, it is difficult to obtain the original design drawings. Therefore, on-site measurements of the building must be taken before developing a demolition plan. The measurement work is basically done manually, and various measurement data need to be manually compiled and drawn up for use in the development of the demolition plan.

[0003] In the prior art, such as the drawing device for building structure inspection with announcement number CN212014866U, there is a workbench with four mounting holes on the bottom. Each of the four mounting holes is threaded with a connecting stud. This drawing device for building structure inspection places support legs and anti-slip pads by opening a first mounting groove and a second mounting groove on the bottom of the workbench. However, in the prior art, the workbench of this drawing device for building structure inspection is a single structure that cannot be rotated, folded, or retracted. Because it cannot be rotated, folded, or retracted, it is inconvenient to carry. Therefore, a drawing device is proposed. Utility Model Content

[0004] In view of this, the present invention aims to provide a drawing device to solve or alleviate the technical problems existing in the prior art. By installing two folding components, the two box components can be rotated, folded and contracted. Because the two box components can rotate and contract, the device becomes smaller in size after rotation and contraction, making the device more portable.

[0005] The technical solution of this utility model embodiment is implemented as follows:

[0006] A drawing device includes two housing assemblies, with two rotating blocks and a folding assembly rotatably connected between the two housing assemblies. The folding assembly includes a connecting piece and two folding square rods rotatably disposed at both ends of the connecting piece. The two folding square rods are rotatably connected to the two housing assemblies respectively. A threaded rod that is threadedly connected to the rotating blocks is rotatably connected to the connecting piece. Four support assemblies are rotatably connected to each of the two housing assemblies. Each support assembly includes a connecting seat that is rotatably connected to the housing assembly and a rotating leg that is slidably connected to the connecting seat. The top of the rotating leg is threadedly connected to the housing assembly. A handle is fixedly installed on one side of each of the two housing assemblies.

[0007] Preferably, the housing assembly includes a rotating housing, a sliding plate that is slidably disposed inside the rotating housing, and two fixing locks are fixedly installed between the two rotating housings. The installation of the fixing locks facilitates the fixation of the two rotating housings.

[0008] Preferably, two positioning balls are fixedly installed on one of the rotating boxes, and a notch corresponding to the positioning balls is opened on the other rotating box. The positioning balls are hemispherical in shape. The installation of the positioning balls can position the two rotating boxes, so that the two rotating boxes are not prone to displacement after rotation.

[0009] Preferably, both the rotating box and the rotating block are provided with circular holes that rotate and cooperate with each other. The rotating block is provided with a first threaded hole. The bottom thread of the threaded rod is provided inside the first threaded hole. The lower surfaces of the rotating block and the rotating box are provided with limit protrusions. The limit protrusions can limit the rotating box and the rotating block, so that the rotating box and the rotating block can stop rotating after rotating 90°.

[0010] Preferably, both rotating boxes are provided with multiple cavities for storage, and both ends of the two rotating boxes are provided with a first groove for accommodating the folded square rod. The opening of the first groove facilitates the storage of the folded square rod.

[0011] Preferably, each of the two rotating boxes has two second grooves for accommodating four support components. The support components are rotatably fitted in the second grooves. Anchor bolts are threadedly fitted at the bottom of the rotating legs. The rotating box has multiple second threaded holes for fixing the rotating legs. The opening of the second grooves facilitates the storage of the rotating legs.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model, through the installation of two folding components, can drive two box components to rotate, fold, and retract. Because the two box components can rotate and retract, the device becomes smaller in size after rotation and retraction, making the device more portable.

[0014] Second, by installing the support components, this utility model can support the box assembly, making it easier for workers to draw on the sliding plate after the box assembly is supported.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, this utility model embodiment provides a drawing device, including: two box assemblies 1, two rotating blocks 2 rotatably coupled between the two box assemblies 1, and a folding assembly 3. The folding assembly 3 includes a connecting piece 4 and two folding square rods 5 rotatably coupled at both ends of the connecting piece 4. The two folding square rods 5 are rotatably coupled with the two box assemblies 1 respectively. A threaded rod 14 rotatably coupled with the rotating block 2 is provided on the connecting piece 4. Four support assemblies 6 are rotatably coupled on each of the two box assemblies 1. The support assemblies 6 include a connecting seat 7 rotatably coupled with the box assemblies 1 and a rotating leg 8 slidably coupled with the connecting seat 7. The top of the rotating leg 8 is threadedly coupled with the box assemblies 1. A handle 9 is fixedly installed on one side of each of the two box assemblies 1.

[0025] In this embodiment, specifically: the box assembly 1 includes a rotating box 10 and a sliding plate 11 that is slidably disposed inside the rotating box 10. Two fixing locks 12 are fixedly installed between the two rotating boxes 10. The installation of the sliding plate 11 facilitates the drawing work on it by the staff.

[0026] In this embodiment, specifically: two positioning balls 13 are fixedly installed on one of the rotating boxes 10, and a notch corresponding to the positioning ball 13 is opened on the other rotating box 10. The positioning ball 13 has a hemispherical structure, and the notch facilitates the positioning of the two rotating boxes 10.

[0027] In this embodiment, specifically: both the rotating box 10 and the rotating block 2 are provided with circular holes that rotate and cooperate with each other, the rotating block 2 is provided with a first threaded hole, the bottom of the threaded rod 14 is threaded and fitted inside the first threaded hole, and the lower surfaces of the rotating block 2 and the rotating box 10 are provided with limit protrusions 201. The opening of the first threaded hole facilitates the threaded cooperation between the rotating block 2 and the threaded rod 14.

[0028] In this embodiment, specifically: both rotating boxes 10 are provided with multiple cavities 1001 for storage, and both ends of the two rotating boxes 10 are provided with first grooves 1002 for accommodating folded square rods 5. The opening of the cavities 1001 facilitates the storage of items.

[0029] In this embodiment, specifically: each of the two rotating boxes 10 has two second grooves 1003 for accommodating four support components 6. The support components 6 are rotatably fitted in the second grooves 1003. The bottom of the rotating leg 8 is threadedly fitted with anchor bolts 15. The rotating box 10 has multiple second threaded holes for fixing the rotating leg 8. The installation of the anchor bolts 15 facilitates the use of the device on uneven ground.

[0030] When this utility model is in operation: when the device needs to be folded and retracted, the threaded rod 14 is rotated. After the threaded rod 14 rotates, it separates from the rotating block 2. Then, the two box assemblies 1 are rotated and folded and retracted. Then, the two folding assemblies 3 are folded and retracted. After the two box assemblies 1 are rotated and folded, the area occupied by the two box assemblies 1 is smaller, which makes the device easier to carry.

[0031] When the support component 6 in the device needs to support the device, the support component 6 is in a horizontal state. Then, rotate the rotating leg 8. After the rotating leg 8 rotates, it disengages from the rotating box 10. Then, rotate the connecting seat 7. The rotation of the connecting seat 7 drives the rotating leg 8 to rotate. When the rotating leg 8 rotates 90°, the rotating leg 8 is in a vertical state. Then, rotate the rotating leg 8. During the rotation of the rotating leg 8, it spirals into the interior of the rotating box 10. Then, the rotating leg 8 is threaded and fixed inside the rotating box 10. Then, the rotating leg 8 supports the rotating box 10. At this time, drawing can be performed on the sliding plate 11.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
