Description

Technical Field

[0001] The utility model relates to the technical field of side-pressure door and window accessories, in particular to a side-pressure locking mechanism. Background Art

[0002] Sliding doors and windows are widely used because they do not occupy indoor space, have beautiful appearance, and are flexible to open. Reference application number: 202410075402.1 is a side lock device and door and window system for sliding doors and windows. In order to improve the sealing effect of sliding windows, a side pressure sliding door and window has been derived with the development of sliding doors and windows. In the closed state, by turning the handle, the transmission rod drives the side pressure device to make the movable sash move inward / outward horizontally so that it presses against the window frame to improve the overall sealing performance. However, the side pressure structure is a gear assembly that directly converts the longitudinal movement of the transmission rod into a lateral movement to drive the door and window sash to move horizontally and press the outer frame. In this process, the rubber strips between the frame and the sash need to be squeezed and matched, and the transmission structure design is not reasonable, resulting in greater resistance during the side pressure process. In addition, the current movable sash is heavy, and people encounter greater resistance when turning the handle, especially for the elderly or children who find it difficult to turn the handle to achieve side pressure, which seriously affects the user experience.

A positioning hole 20 and an opening 30 are provided on a side of the base 1 facing the movable part 2. A first slider 31 slidably connected to the strip groove 10 is provided on one side of the transmission part 3, and a positioning column 33 inserted into the positioning hole 20 and a second slider 32 slidably connected to the opening 30 are provided on the other side. The first slider 31 is arranged at an eccentric position between the second slider 32 and the positioning column 33, and is close to the positioning column 33. The opening 30 is used to provide a space for the second slider 32 to move. It should be understood that the opening 30 and the strip groove 10 are mainly used to provide a space for the second slider 32 and the first slider 31 to move. The shapes of the opening 30 and the strip groove 10 can be further confirmed according to the movement trajectories of the first slider 31 and the second slider 32. Figure 1 , 3 The opening 30 is arranged in an arc shape, and the opening 30 and the positioning hole 20 are arranged concentrically. The concentric arrangement allows the second slider 32 to swing in an arc according to the arc of the opening 30 with the positioning post 33 as the center.

[0020] The utility model discloses a side pressure locking mechanism, the movable part 2 and the base 1 make relative transverse sliding through the transmission part 3, the positioning column 33 on the transmission part 3 is used as a fixed point, and the second slider 32 is used to move along the arc of the opening 30, so as to drive the first slider 31 to move, so that the movable part 2 makes relative transverse movement, and the position distribution of the first slider 31, the second slider 32 and the positioning column 33 on the transmission part 3 is used, and the lever principle is used, with the positioning column 33 as the origin, and the second slider 32 far from the positioning column 33 drives the first slider 31 close to the positioning column 33, so as to improve the mechanical structure of the side pressure locking mechanism, achieve the effect of labor saving, stability and smoothness, reduce resistance, so that people can easily turn the handle, so that the user experience is better, and the side pressure locking structure replaces the existing side pressure structure, and the force distance of the handle is shorter during the side pressure process.

[0021] In this embodiment, the base 1 is fixedly installed on the movable sash, and there is a connecting hole on the base 1, which can be fixedly connected to the movable sash by screws. The transmission member 3 is connected to the transmission rod 300 set on the movable sash, specifically, the second slider 32 on the transmission member 3 is connected to the transmission rod 300, and the transmission rod 300 is connected to the handle. This belongs to the transmission structure of existing doors and windows. The transmission rod 300 is provided with a long strip of through grooves, and the length direction of the through grooves corresponds to the thickness direction of the doors and windows. The second slider 32 protrudes from the opening 30 and is inserted into the through groove. Furthermore, the groove width of the through groove corresponds to the diameter of the second slider 32. By turning the handle, the second slider 32 of the transmission member 3 is driven by the transmission rod 300, so that the second slider 32 swings around the positioning column 33, thereby causing the movable member 2 to slide horizontally.

[0022] like Figure 4-5 As shown, the transmission member 3 is divided into an a section 301 and a b section 302 in the sliding direction of the movable member 2. The a section 301 and the b section 302 are two isosceles triangles with the same base. The waist portion of the a section 301 is larger than the waist portion of the b section 302. The positioning column 33 is arranged at the top corner of the b section 302. The second slider 32 is arranged at the top corner of the a section 301. The first slider 31 is arranged on one waist portion of the b section 302. The bases of the a section 301 and the b section 302 are the same. It can also be regarded that the positioning column 33, the first slider 31 and the second slider 32 constitute the corners of the triangle, and The side between the first slider 31 and the second slider 32 is a short side. The first slider 31 can be set on one of the waist sides or the bottom corner of the b section 302. By changing the position of the first slider 31 in the b section 302, that is, changing the distance between the first slider 31 and the positioning column 33, it can be seen that when the transmission member 3 is swung during side pressure, the distance between the first slider 31 and the positioning column 33 is equal to the side pressure distance. The side pressure distance can be adjusted by setting the distance between the first slider 31 and the positioning column 33. In actual applications, the side pressure distances of different side pressure doors and windows are different. Different transmission members 3 can be set according to the side pressure distances of different side pressure doors and windows.

[0023] In this embodiment, the diameter of the first slider 31 corresponds to the diameter of the second slider 32. Figure 1 As shown, the opening 30 is set to a preferred arc shape, and the groove width of the opening 30 corresponds to the groove width of the strip groove 10, the first slider 31 and the second slider 32 have the same diameter, the groove width of the opening 30 is equal to the groove width of the strip groove 10, and the diameters of the first slider 31 and the second slider 32 are matched to the groove widths of the strip groove and the opening 30 respectively to prevent them from having loose gaps.

[0024] In this embodiment, the movable member 2 is recessed with a slide groove 211, and the base 1 is provided with a sliding portion 111 that slides in the slide groove 211. The relative sliding of the movable member 2 and the base 1 is achieved by the cooperation between the sliding portion 111 and the slide groove 211. Figure 6 As shown, limit blocks are arranged on both sides of the movable part 2, and the limit blocks are fixedly connected to the base 1. The movable part 2 is provided with protrusions on the corresponding two sides, and the limit blocks are arranged to match the recesses of the protrusions to prevent the movable part 2 from escaping from the base 1. The sliding part 111 is provided with a sliding part 44, and the sliding part 44 is located between the sliding part 111 and the slide groove 211. The sliding part 44 contacts the movable part 2 and the base 1, so that the movable part 2 and the base 1 can slide more smoothly. The sliding part 44 can be a ball or a graphite slide, etc., refer to Figure 1 If a ball bearing is used, a groove for accommodating the sliding member 44 may be further provided on the sliding groove 211 or the surface of the sliding portion 111 to prevent the ball bearing from shifting.
