The center of the window opener can be adjusted as needed to improve the adaptability of the window opener. A through hole is provided in the middle of the positioning platform 11. 111, the crown buckle 3 is matched with the through hole 111, the first end of the crown buckle 3 has a boss 31 for clamping the bracket 2, and the second end of the crown buckle 3 has a clamping structure 32 for clamping the through hole 111, and the bracket 2 and the crown buckle 3 are axially limited and prevented from falling off through the boss 31 and the clamping structure 32. The crown buckle 3 is a hollow structure, and the tightening plug 4 is movably arranged in the crown buckle 3 to lock the crown buckle 3 and the positioning platform 11. After the window opener is installed in place, it is locked by tightening the plug 4 to limit the bracket 2 axially to prevent it from falling off.

[0032] There is no limit on the number of pre-adjustment holes 21, as long as the above technical effects can be achieved. The bracket 2 is formed with two, three, or more pre-adjustment holes 21 in the longitudinal direction, and is installed in conjunction with the positioning platform 11 to fix the chain box 1, and the longitudinal pre-adjustment holes 21 can adjust the chain box 1 in the longitudinal space. The pre-adjustment holes 21 on the bracket 2 adopt a multi-hole position design and can be adjusted as needed, thereby improving the adaptability of the product.

[0033] The center-adjustable window opener arranged in the above manner can achieve the effects of quick installation, anti-dropping and center adjustment. The crown buckle 3 and the tightening plug 4 are used to limit the window opener bracket 2 and prevent it from dropping out. There is no need for pre-installation in advance. The pre-adjustment hole 21 is reserved in advance for the bracket 2 to facilitate on-site installation and adjustment.

[0034] Please refer to Figure 3 The clamping structure 32 includes a clamping body 321 , and a sliding groove 322 extending along the axial direction of the clamping body 321 is provided on the clamping body 321 .

[0035] It should be noted that the positioning of the crown buckle 3 and the positioning platform 11 is achieved through the clamping structure 32, so as to prevent the crown buckle 3 from being separated from the positioning platform 11 during use, thereby causing the window opener to fall off.

[0036] In the above situation, at least two slide grooves 322 are provided, and at least two slide grooves 322 are provided in the circumferential direction of the engaging body 321 .

[0037] It can be understood that by providing the slide groove 322, the movement and coordination between the screw plug 4 and the crown buckle 3 is realized, so that the screw plug 4 can be directly inserted into the hole of the crown buckle 3, which is simple to operate and has high installation efficiency.

[0038] There is no limitation on the number, position and size of the slide grooves 322 as long as the above-mentioned technical effects can be achieved.

[0039] Furthermore, an undercut rib 323 is provided between two adjacent slide grooves 322 , and at least two undercut ribs 323 are provided, and at least two undercut ribs 323 are provided in the circumferential direction of the clamping body 321 .

In real life, there is no restriction on the number, position and size of the undercut ribs 323, as long as the above technical effect can be achieved.

[0041] In the above embodiment, a buckle groove 324 is provided at the inner side of the end of the undercut rib 323 .

[0042] It can be understood that the inner end of each undercut rib 323 has a buckle groove 324, and there are slide grooves 322 between adjacent undercut ribs 323. The buckle groove 324 extends toward the outer end of the crown buckle 3, and a groove is formed on the inner annular surface of the crown buckle 3. The buckle groove 324 is communicated with the slide groove 322. The crown buckle 3 passes through the pre-adjustment hole 21, and the undercut rib 323 is inserted into the through hole 111 of the positioning platform 11 and buckled with the inside of the through hole 111 of the positioning platform 11. The threaded connection method in the prior art is replaced by the direct insertion buckle method, which makes assembly and disassembly more convenient and improves assembly efficiency.

[0043] On the basis of the above embodiment, the first end of the tightening plug 4 is provided with a clamping platform 41 clamped with the boss 31, and the second end of the tightening plug 4 is circumferentially provided with a locking platform 42, which is movable along the slide groove 322, and the locking platform 42 is matched with the buckle groove 324.

[0044] It should be noted that the bracket 2 is clamped by the clamping platform 41 of the crown buckle 3 to achieve the fixation of the bracket 2. The tightening plug 4 is columnar, and the inner end of the tightening plug 4 has a protruding locking platform 42, which cooperates with the buckle groove 324 of the inner annular surface of the crown buckle 3. The locking platform 42 slides inward along the slide groove 322, and then the tightening plug 4 is rotated, and the locking platform 42 is clamped with the buckle groove 324 of the undercut rib 323 to achieve locking, further strengthening the installation structure and increasing the stability of the structure.

[0045] As a preferred embodiment, the opening between two adjacent pre-adjustment holes 21 is set smaller than one third of the diameter of the positioning platform 11 .

[0046] It can be understood that two adjacent pre-adjustment holes 21 are connected, and the opening is smaller than one-third of the diameter of the positioning platform 11 , thereby saving materials while ensuring connection stability.

[0047] There is no restriction on the diameter of the through opening as long as the above-mentioned technical effect can be achieved.
