Abstract
Description
Technical Field
[0001] This utility model relates to a transmission structure for an inward-opening and inward-tilting window. Background Technology
[0002] An inward-opening and tilt-and-turn window is a type of window that can open vertically by 90° towards the interior, or tilt inward slightly horizontally. Existing inward-opening and tilt-and-turn structures generally include a drive rod and a corner mechanism, as illustrated in Chinese utility model patents CN219711341U, CN217872449U, CN215169318U, and CN217999380U. In these structures, the drive rod is inserted into a groove in the window sash and has a through hole. The corner mechanism has connecting posts at both ends, and the corner mechanism is connected to the drive rod via the connecting posts passing through the through hole. (See CN219711341U appendix for details.) Figure 4 (See attached figure 17 of CN217872449U). For window sashes of different sizes, it is necessary to cut transmission rods of different sizes and then drill holes in the transmission rods. The process is quite complicated, and if the transmission rod is cut too small or the hole is drilled incorrectly, the transmission rod will have to be scrapped. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a transmission structure for an inward-opening and inward-tilting window, including a corner mechanism and a transmission rod. The corner mechanism includes an L-shaped base, a first pull rod, a second pull rod, and a transmission spring. The base has a first sliding groove and a second sliding groove on both sides. The first pull rod and the second pull rod can slide in the first sliding groove and the second sliding groove respectively. One end of the first pull rod and one end of the second pull rod are connected by the transmission spring to achieve linkage. The transmission rod is set in the sliding groove of the window sash of the inward-opening and inward-tilting window. The transmission rod has a third sliding groove. The outward-facing ends of the first pull rod and the second pull rod are respectively provided with a first sliding block and a second sliding block that cooperate with the third sliding groove. The installation position of the transmission rod can be adjusted by sliding the transmission rod or the first pull rod.
[0005] The first slider part and the second slider part are respectively provided with a first threaded hole and a second threaded hole, and screws are provided in the first threaded hole and the second threaded hole. The first slider part and the second slider part are fixedly connected by screws and transmission rod.
[0006] The third groove is a T-shaped groove.
[0007] It also includes a middle connector, which has a third slider portion that cooperates with the third slide groove.
[0008] The middle connector has a third threaded hole at both ends, and a screw is installed in the third threaded hole. The middle connector is fixedly connected to the transmission rod by the screw.
[0009] It also includes a flip support, one end of which is provided with a fourth slider that cooperates with the third slide groove.
[0010] The fourth slider part is provided with a fourth threaded hole, and a screw is provided in the fourth threaded hole. The flip support is fixedly connected to the transmission rod by the screw.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a first slider part and a second slider part that cooperate with the third sliding groove of the transmission rod at the outward end of the first pull rod and the second pull rod, respectively. The installation position of the transmission rod can be adjusted by sliding the transmission rod or the first pull rod, so that the transmission rod can be used for window sashes within a certain size range. Moreover, no holes need to be drilled on the transmission rod, making assembly more convenient. Attached Figure Description

[0020] like Figures 1-8As shown, a transmission structure for an inward-opening and tilt-and-turn window includes a corner mechanism 1 and a transmission rod 2. The corner mechanism 1 includes an L-shaped base 101, a first pull rod 102, a second pull rod 103, and a transmission spring 104. The base 101 has a first sliding groove 105 and a second sliding groove 106 on both sides. The first pull rod 102 and the second pull rod 103 can slide in the first sliding groove 105 and the second sliding groove 106 respectively. One end of the first pull rod 102 and one end of the second pull rod 103 are connected by the transmission spring 104 to achieve linkage. The transmission rod 2 is set in the sliding groove of the window sash of the inward-opening and tilt-and-turn window. The transmission rod 2 has a third sliding groove 201. The outward-facing ends of the first pull rod 102 and the second pull rod 103 are respectively provided with a first sliding block 107 and a second sliding block 108 that cooperate with the third sliding groove 201. The installation position of the transmission rod 2 can be adjusted by sliding the transmission rod 2 or the first pull rod 102.
[0021] The first slider part 107 and the second slider part 108 are respectively provided with a first threaded hole 109 and a second threaded hole 110. Screws 3 are provided in the first threaded hole 109 and the second threaded hole 110. The first slider part 107 and the second slider part 108 are fixedly connected to the transmission rod 2 by the screws 3.
[0022] like Figure 6 As shown, the third groove 201 is a T-shaped groove.
[0023] It also includes a middle connector 4, which has a third slider portion 401 that mates with the third sliding groove 201. The middle connector 4 has third threaded holes 402 at both ends, and screws 3 are installed in the third threaded holes 402. The middle connector 4 is fixedly connected to the transmission rod 2 by the screws 3. In the prior art, the middle connector of the inward-opening and inward-tilting window is used for transmission between the handle and the transmission rod. Using the existing connection method, the middle connector has transmission rods at the top and bottom, and the two ends of the middle connector mate with openings on the transmission rods via connecting posts (refer to Figure 11 of CN217872449U and Figure 11 of CN219711341U). Figure 4 With the solution of this utility model, the connecting part 4 can slide to any position on the transmission rod 2, which is convenient for adjustment. Moreover, only one transmission rod 2 needs to be set, making assembly more convenient.
[0024] The system also includes a flip support 5, one end of which has a fourth slider portion 501 that mates with the third sliding groove 201. The fourth slider portion 501 has a fourth threaded hole 502, and a screw 3 is installed inside the fourth threaded hole 502. The flip support 5 is fixedly connected to the transmission rod 2 by the screw 3. In the prior art, the connection method between the flip support and the transmission rod is similar to that between the corner device and the transmission rod, requiring the size and opening of the transmission rod connected to the flip support to be precisely matched, leaving no room for adjustment. Using the solution of this utility model, the transmission rod 2 can slide up and down relative to the flip support 5, facilitating adjustment.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Structures of components not described in the specification may employ conventional structures found in the prior art. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Simple modifications and substitutions made by those skilled in the art without departing from the spirit and scope of this utility model are within its protection scope.
