[0036] See also Figure 1-8 The embodiment of the present application provides an auxiliary positioning device for unit curtain wall window construction, including a positioning frame 100 and a supporting mechanism 200. The positioning frame 100 is configured to be able to expand and contract, and the supporting mechanism 200 is located inside the positioning frame 100. The positioning frame 100 includes four L-shaped positioning blocks 110 and four strip positioning blocks 120. The four L-shaped positioning blocks 110 and the four strip positioning blocks 120 together form a rectangle. The four L-shaped positioning blocks 110 are located at the four corners of the rectangle, and the four strip positioning blocks 120 are located at the four sides of the rectangle. The two ends of each strip positioning block 120 and the corresponding L-shaped positioning block 110 are connected through a multi-link telescopic mechanism 130. The support mechanism 200 is configured as a cross-shaped structure including eight telescopic arms, wherein four telescopic arms are respectively connected to four L-shaped positioning blocks 110, and the other four telescopic arms are respectively connected to four strip-shaped positioning blocks 120. The support mechanism 200 is configured to be able to drive the positioning frame 100 to expand and contract. When the window frame of the unit curtain wall needs to be installed with a window, the auxiliary positioning device for the construction of the unit curtain wall window is placed in the window frame, and the expansion of the positioning frame 100 is driven to connect with the inner side of the window frame through the telescopic movement of the support mechanism 200, and then the window is installed in the window frame. The installation of the window can be positioned by the auxiliary positioning device for the construction of the unit curtain wall window. The auxiliary positioning device for the construction of the unit curtain wall window can change the size of the positioning frame 100, so as to adapt to window frames of different sizes.

[0037] In some embodiments, four bar-shaped positioning blocks 120 are located in the middle of the four sides of the rectangle to accommodate the connection of the support mechanism 200 of the cross-shaped structure and to improve the structural stability.

[0038] In some embodiments, the multi-link telescopic mechanism 130 includes at least two cross connectors 131 and four connecting rod assemblies 133, and the four connecting rod assemblies 133 are rotatably connected to the four connecting ends of the two cross connectors 131 respectively; the cross connectors 131 at both ends are provided with connecting plates 132, and the connecting plates 132 are configured to be fixedly connected to the L-shaped positioning block 110 and the bar positioning block 120. By using the multi-link telescopic mechanism 130, the positioning frame 100 can be smoother and more stable when performing expansion movement, thereby increasing the stability and firmness of the positioning frame 100.

[0039] Specific to Figure 3 In the illustrated embodiment, there are four cross connectors 131 , and the connecting rod assembly 133 is a four-link assembly that cooperates therewith.

[0040] It is understandable that the number of the cross connectors 131 is generally the same as the number of the connecting rods of the connecting rod assembly 133 , and the number of the cross connectors 131 and the number of the connecting rods of the connecting rod assembly 133 depend on the required length of the multi-link telescopic mechanism 130 .

[0041] In some embodiments, the four telescopic arms connected to the four L-shaped positioning blocks 110 are active telescopic arms, and have a driving mechanism to drive the telescopic arms to achieve telescopic movement. The four telescopic arms connected to the four L-shaped positioning blocks 110 are active telescopic arms, which are mainly used to actively drive the four L-shaped positioning blocks 110 to improve the smoothness of the positioning frame 100 when expanding.

[0042] It is understandable that the other four telescopic arms may be active telescopic arms or non-driven passive telescopic arms. For cost considerations, passive telescopic arms may be used.

[0043] In some embodiments, the support mechanism 200 includes a first cross support frame 210 and a second cross support frame 220 . The first cross support frame 210 and the second cross support frame 220 both have four telescopic arms. The cross-shaped structure is formed by the first cross support frame 210 and the second cross support frame 220 .

[0044] In a further embodiment, the first cross support frame 210 includes a central sleeve 211, four outer square rectangular tubes 213 and four inner square rectangular tubes 214. The four outer square rectangular tubes 213 are evenly fixed on the central sleeve 211, and the four inner square rectangular tubes 214 are respectively inserted into the four outer square rectangular tubes 213. The four inner square rectangular tubes 214 are respectively fixedly connected to four strip-shaped positioning blocks 120. The passive telescopic arm using the square rectangular tube structure will not rotate, which can prevent the positioning frame 100 from twisting and deforming.

[0045] Furthermore, four through holes 212 are opened on the tube wall of the central sleeve 211 , and a first mounting plate 224 and a second mounting plate 225 are fixedly connected to both ends of the central sleeve 211 .

[0046] In a further embodiment, the second cross support frame 220 includes four scissor-type telescopic mechanisms 226 and four top plates 222. The mounting ends of the four scissor-type telescopic mechanisms 226 are mounted in the central sleeve 211. The four scissor-type telescopic mechanisms 226 are respectively connected to the four top plates 222 through the four through holes 212. The scissor-type telescopic mechanisms 226 are configured to drive the top plates 222 to move linearly. The four top plates 222 are respectively connected to four L-shaped positioning blocks 110. The use of the scissor-type telescopic mechanisms 226 can save space and provide a larger telescopic stroke.

[0047] It should be noted that the scissors-type telescopic mechanism 226 is an existing conventional scissors-type telescopic mechanism, which mainly includes a scissors structure and a driving mechanism. The driving mechanism generally adopts a pneumatic cylinder, an oil cylinder, an electric cylinder, etc., similar to a scissors-type lift. Since it is an existing structure, it will not be described in detail.

[0048] In a further embodiment, in order to save costs, reduce volume, and improve the synchronization of the movement of the four top plates 222, see Figure 7 , the four scissor-type telescopic mechanisms 226 can share one driving mechanism 227.

[0049] Furthermore, the driving mechanism 227 has a control switch 228, and the control switch 228 is mounted on the first mounting plate 224. The switch is mounted on the positioning device body for easy use.

[0050] In a further embodiment, the second cross support frame 220 further includes four limit frames 223, which are respectively sleeved on the four top plates 222, and the four limit frames 223 are all fixedly connected to the wall of the central sleeve 211. By limiting the movement direction of the top plate 222 by the limit frames 223, possible rotation caused by the scissor-type telescopic mechanism 226 can be avoided, and the positioning frame 100 can be prevented from being twisted and deformed.

[0051] Furthermore, the end of the top plate 222 has an angle connecting plate 221 , and the end of the angle connecting plate 221 has a right-angle structure, which is connected to the inner corner of the L-shaped positioning block 110 to facilitate connection and prevent the positioning frame 100 from twisting and deforming.

[0052] In summary, the method for using the auxiliary positioning device for unitized curtain wall window construction (hereinafter referred to as "positioning device") provided in the above preferred embodiment includes:

[0053] Step 1: When the unitized curtain wall needs to be constructed and installed with windows, the positioning device is placed in the window frame where the window needs to be installed, and then the control switch 228 is pressed to drive the driving mechanism 227 to move, so that the scissor-type telescopic mechanism 226 is extended;

[0054] Step 2: As the scissor-type telescopic mechanism 226 extends, the top plate 222 drives the L-shaped positioning block 110 to move outward, so that the positioning frame 100 expands and becomes larger until it hits the inner wall of the window frame and is fixed; release the control switch 228 to stop the expansion movement;

[0055] Step 3: After the positioning frame 100 is positioned and installed on the window frame of the curtain wall, the window is installed in the window frame. The positioning device can assist in the positioning of the window, thereby facilitating the installation of the window.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
