[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that the directional words such as "left" and "right" below are defined based on the drawings in the specification.

[0035] The core of the utility model is to provide a chain box window opener, the inner cavity of the chain guide box 1 is a multi-layer structure, which is used to accommodate the multi-layer chain 2 and can constrain the movement trajectory of the chain 2, thereby shortening the length of the window opener and facilitating the installation of the window opener on a narrow window.

[0036] Please refer to Figure 1 A chain box window opener includes a chain guide box 1, a chain 2 and an operating mechanism 3.

[0037] Specifically, the inner cavity of the chain guide box 1 is a multi-layer connected structure, and the chain 2 is movably arranged in the inner cavity of the chain guide box 1, so that a chain 2 can be coiled around the multi-layer connected structure of the inner cavity of the chain guide box 1. The multi-layer connected structure of the chain guide box 1 separates a chain 2 so that the chain 2 can enter and exit the chain guide box 1 in an orderly manner to avoid entanglement or interference of the chain 2. By setting the multi-layer connected structure, a chain 2 can be rotated and folded and stored in the chain guide box 1. The operating mechanism 3 is arranged at the end of the chain guide box 1 and connected to the end of the chain guide box 1. The operating mechanism 3 is used to control the movement of the chain 2. By setting the inner cavity of the chain guide box 1 as a multi-layer structure, the length of the window opener is shortened, which facilitates the installation of the window opener on a narrow window.

[0038] Among them, the multi-layer connecting structure divides the inner cavity of the chain guide box 1 into a multi-layer cavity structure for loading the long chain 2, so that the long chain 2 can be loaded and stored in the inner cavity of the chain guide box 1 in a bent manner, and the length of the chain guide box 1 can be shortened to adapt to the size requirements of different narrow window sashes, and the long chain 2 can smoothly enter and exit the chain guide box 1 along the multi-layer connecting structure. The multi-layer connecting structure also plays a guiding role.

[0039] The chain box window opener arranged in the above manner has a chain box 1 with a multi-layer structure in its inner cavity, so that the chain box 1 with the same travel specification has a shorter length to meet the size requirements of narrow window sashes.

[0040] Please refer to Figure 2 The chain guide box 1 includes a front chain guide box 11, a middle chain guide box 12 and a rear chain guide box 13. The first end of the front chain guide box 11 is connected to the operating mechanism 3, the first end of the front chain guide box 11 is connected to the second end of the front chain guide box 11, and the first end of the front chain guide box 11 is connected to the second end of the middle chain guide box 12.

[0041] It should be noted that the front chain guide box 11, the middle chain guide box 12 and the rear chain guide box 13 are assembled and combined for easy assembly and maintenance. In one embodiment, the chain guide box 1 is directly formed by the left and right parts of the box body being clamped together, which is also easy to assemble and maintain, and the disassembly process is simpler and faster.

[0042] Among them, in this embodiment, the chain guide box 1 includes a front chain guide box 11, a middle chain guide box 12 and a rear chain guide box 13, but in actual life, the chain guide box 1 can also be set as an integrated structure, without limitation, as long as the above-mentioned technical effects can be achieved.

[0043] Furthermore, there is no limitation on the size, shape, etc. of the chain guide box 1, as long as the above-mentioned technical effects can be achieved.

[0044] In the above situation, both the front chain guide box 11 and the rear chain guide box 13 are provided with an arc-shaped inner chain guide flange 4 and an outer chain guide flange 5, and a double-layer chain guide track is provided between the inner chain guide flange 4 and the outer chain guide flange 5.

[0045] It can be understood that a single-layer chain guide track is formed between the inner chain guide flange 4 and the outer chain guide flange 5, and the space between the inner chain guide flanges 4 is a double-layer chain guide track. The inner chain guide flange 4 and the outer chain guide flange 5 of the chain guide box 1 cooperate to accommodate multiple layers of chains 2 and can constrain the movement trajectory of the chain 2, thereby shortening the length of the window opener, which is suitable for narrow windows.

[0046] There are no restrictions on the size of the inner chain guide flange 4 and the outer chain guide flange 5 and the number of chain guide tracks formed, and they can be adjusted according to the length and specifications of the chain 2 as long as the above-mentioned technical effects can be achieved.

[0047] Furthermore, a partition strip 6 is provided in the inner cavity of the rear chain guide box 13 , and the partition strip 6 is located between the inner chain guide flanges 4 .

[0048] It should be noted that the separator bar 6 plays a role of separating the double-layer chain guide track. There is no restriction on the size of the separator bar 6, and it can be adjusted according to the length and specification of the chain 2, as long as the above-mentioned technical effect can be achieved.

[0049] In the above embodiment, the front chain guide case 11 and the rear chain guide case 13 are both formed by snap-joining two case bodies.

[0050] It is understandable that the front chain guide box 11 and the rear chain guide box 13 include two left and right box parts, which are assembled and formed to facilitate assembly and maintenance. In actual life, the front chain guide box 11 and the rear chain guide box 13 can also be set as an integrated structure, which is not limited as long as the above technical effects can be achieved.

[0051] Please refer to Figure 1 A limiting mechanism 7 and a torsion spring 8 are provided on the operating mechanism 3, and the limiting mechanism 7 and the torsion spring 8 are arranged in coordination.

[0052] It should be noted that the chain 2 is stored in the inner cavity of the multi-layer chain guide box 1. When opening, the chain 2 extends outward one by one under the action of the operating mechanism 3. When the last section of the chain 2 is about to reach the operating mechanism 3, the chain 2 starts to move under the action of the limiting mechanism 7 and the torsion spring 8 until the chain 2 is completely locked, completing the opening process; when closing, the chain 2 is under the action of the operating mechanism 3, and the chain 2 enters the multi-layer chain 2 containing body until the chain 2 is completely received therein, completing the closing process.

[0053] In summary, the chain box window opener provided by the utility model can solve the length problem of the chain box. By folding the chain 2 multiple times in the inner cavity of the chain guide box 1, the chain guide box 1 with the same stroke specification has a shorter length, which is convenient for installation in a relatively narrow space.

[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0056] The above is a detailed introduction to a chain box window opener provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
