[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 3 A micro-adjustable sliding door and window extension rod structure includes a fixed rod 100, a movable rod 200, a connector 300, and a micro-adjustment unit 400. The fixed rod 100 is provided with a sliding groove 110 along its length. The movable rod 200 is disposed in the sliding groove 110 and can slide along the sliding groove 100. The connector 300 is connected to the bottom end of the movable rod 200 through the micro-adjustment unit 400. The micro-adjustment unit 400 can make micro-adjustments between the connector 300 and the movable rod 200.

[0029] Specifically, in this embodiment, the fixed rod 100 is connected to the fixed plate part of the door and window actuator, and the lower end of the moving rod 200 is connected to the sliding plate part of the door and window actuator through the connecting piece 300. Therefore, the sliding plate part of the door and window actuator and the moving plate 200 can move synchronously, while the fixed plate part of the door and window actuator and the fixed rod 100 remain fixed. By cooperating with the fixed rod 100, the moving rod 200 and the connecting piece 300 with the door and window actuator, the length of the door and window actuator can be extended to meet the height specifications of more door leaves or windows. To facilitate the assembly of the extension rod and the door / window actuator, the connector 300 is connected to the bottom end of the moving rod 200 via a fine-tuning unit 400. The fine-tuning unit 400 fine-tunes the position of the connector 300, thereby allowing for fine-tuning of the sliding plate portion of the moving rod 200 and the door / window actuator. This facilitates the assembly of the extension rod and the door / window actuator, making assembly convenient. At the same time, fine-tuning the position of the connector 300 via the fine-tuning unit 400 also ensures the overall accuracy during the assembly of the extension rod, thus guaranteeing the subsequent assembly quality.

[0030] Please see Figure 2 or Figure 3 To achieve fine adjustment of the connector 300, the fine adjustment unit 400 in this embodiment includes a plurality of fine adjustment holes 410 disposed at the bottom end of the moving rod 200 and a fine adjustment block 420 movably disposed on the connector 300. The plurality of fine adjustment holes 410 are arranged along the length direction of the moving rod 200, and the fine adjustment block 420 is provided with a connecting post 421 corresponding to the fine adjustment hole 410. In addition, a movable cavity 310 is provided in the connector 300, and the fine adjustment block 420 is installed in the movable cavity 310. A fine adjustment nut 430 is threadedly connected to the top of the connector 300, and the lower end of the fine adjustment nut 430 passes through the movable cavity 310 and connects with the fine adjustment block 420. When the connecting post 421 of the fine adjustment block 420 is inserted into the corresponding fine adjustment hole 410, the fine adjustment nut 430 is driven to rotate, so that the connector 300 moves relative to the fine adjustment block 420.

[0031] By arranging several fine-tuning holes 410 at the bottom of the moving rod 200 and inserting the connecting post 421 of the fine-tuning block 420 into the fine-tuning holes 410 at different positions, the connector 300 can be placed at different positions at the bottom of the moving rod 200 to achieve different distances between the bottom of the moving rod 200 and the sliding plate of the door and window actuator, thereby facilitating the assembly of the moving rod 200 and the sliding plate of the door and window actuator. When the connecting post 421 of the fine-tuning block 420 is inserted into the set fine-tuning hole 410, the fine-tuning nut 430 is threadedly connected to the connector 300. Therefore, the fine-tuning nut 430 on the top of the connector 300 can be turned to allow the connector 300 to move relative to the fine-tuning block 420 in the movable cavity 310, thereby fine-tuning the relationship between the moving rod 200 and the sliding plate to ensure the overall accuracy during the assembly of the extension rod and to guarantee the subsequent assembly quality.

[0032] Of course, in order to enable the fine-tuning block 420 in the movable cavity 310 to connect with the fine-tuning nut 430, a slot 431 is provided at the lower end of the fine-tuning nut 430, and a snap-fit ​​part 422 is provided at the top of the fine-tuning block 420. During assembly, the fine-tuning block 420 is installed into the movable cavity 310, and the snap-fit ​​part 422 at the top of the fine-tuning block 420 is snapped into the slot 431 at the lower end of the fine-tuning nut 430, thereby realizing the connection between the fine-tuning block 420 and the fine-tuning nut 430. After the fine-tuning block 420 is installed into the movable cavity 310, its connecting post 421 can be inserted into the corresponding fine-tuning hole 410. Then, by turning the fine-tuning nut 430, the connecting piece 300 can be finely adjusted relative to the fine-tuning block 420.

[0033] Please see Figure 2 In order to assemble the extension rod and enable it to be used normally, in this embodiment, the movable rod 200 is provided with a lock head 210, and the fixed rod 100 is provided with a first through groove 120 for the lock head 210 to pass through. The length of the first through groove 120 is greater than the length of the lock head 210. At the same time, the fixed rod 100 is also provided with a number of positioning holes 130, and the movable rod 200 is provided with a second through groove 220 corresponding to the positioning holes 130. The opening of the sliding groove 110 is also provided with a number of pads 140, and the number of pads 140 corresponds one-to-one with the number of positioning holes 130.

[0034] By connecting the locking screw 150 to the side of the door and window through the positioning hole 130, the second through slot 220 and the pad 140 in sequence, the fixed rod 100 can be assembled and the moving rod 200 is limited in the sliding groove 110 of the fixed rod 100. The connecting piece 300 is connected to the moving rod 200 through the fine adjustment unit 400. The bottom end of the connecting piece 300 can be connected to the sliding part of the door and window actuator through the connecting nut 320, so as to realize the assembly between the extension rod and the door and window actuator.

[0035] Furthermore, the lock head 210 can be fixedly mounted on the moving rod 200 by screws, and when the moving rod 200 slides in the sliding groove 110, the lock head 210 can move in the first through groove 120. In order to ensure that the moving rod 200 can slide, the first through groove 120 and the second through groove 220 are both elongated holes. The elongated first through groove 120 and the second through groove 220 enable the moving rod 200 to slide normally in the sliding groove 110, so that the structure design of the extension rod is reasonable.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
