DETAILED DESCRIPTION
[0028] 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.
[0029] See also Figure 1-6 The embodiment of the utility model provides a limiting device for door and window installation, comprising a sliding member 2, and a locking assembly 3 for fixing is installed on the inner side of the sliding member 2, and a connecting rod 4 for driving the window sash to move is also movably connected to the locking assembly 3;
[0030] The locking assembly 3 comprises a shaft rod 32 with gear teeth integrated at the end thereof, and stop blocks 33 and springs 35 arranged alternately at both sides of the end of the shaft rod 32 , and a rotating handle 31 is fixed to the end of the shaft rod 32 .
[0031] In this embodiment, a tooth groove 34 meshing with the gear teeth at the end of the shaft 32 is formed on a side of the stop block 33 close to the shaft 32 .
[0032] In this embodiment, the sliding member 2 includes a slider 21 that slides with the slide rail 1 and a transverse oil groove 22 and a cross oil groove 23 for storing lubricating oil. The transverse oil groove 22 and the cross oil groove 23 are respectively located on both sides of the slider 21.
[0033] In this embodiment, a sliding cavity 25 is further provided on the inner side of the sliding member 2 , and an opening penetrating the inner side of the sliding cavity 25 is further provided at the diagonal portion of the sliding cavity 25 .
[0034] In this embodiment, a boss 24 is integrally formed on the slider 21 , and the shaft 32 passes through the boss 24 and extends to the inner side of the sliding cavity 25 , and the shaft 32 is movably connected to the slider 21 .
[0035] In this embodiment, the stop blocks 33 are respectively slidably connected to the inner side of the sliding cavity 25 , and the ends of the stop blocks 33 pass through the openings of the sliding cavity 25 .
[0036] In this embodiment, one end of the spring 35 is in contact with the stop block 33 , and the other end is in contact with the inner side of the sliding cavity 25 , so that automatic locking is achieved through the elasticity of the spring 35 .
[0037] In this embodiment, a through hole rotatably matched with the boss 24 is provided on one side of the connecting rod 4 close to the slider 21 , and the other end of the connecting rod 4 is movably connected to the fixing frame 5 .
[0038] In this embodiment, the inner side of the slide rail 1 is symmetrically provided with a slot 11 which is plugged into the end of the stop block 33 , and cooperates with the stop block 33 to lock the position of the slider 21 on the inner side of the slide rail 1 and improve the fixing effect.
[0039] By adopting the above technical solution, the shaft 32 is rotated by rotating the handle 31, and the gear teeth at the end of the shaft 32 are engaged with the tooth grooves 34, driving the stop blocks 33 on both sides to move inward at the same time until the end of the stop block 33 is separated from the inner side of the slot 11, and then the relative position of the sliding member 2 on the inner side of the slide rail 1 is adjusted, and the rotating handle 3 is released. The spring 35 will push the end of the stop block 33 to reinsert into the slot 11, thereby improving the fixing effect and preventing the window sash from sliding at will.
[0040] In this embodiment, the fixing frame 5 is composed of a connecting plate with holes and an ear plate, and the ear plate is movably connected to the connecting rod 4 through a pin, and the ear plates are symmetrically arranged on both sides of the end of the connecting rod 4, so that the connecting rod 4 and the window sash are movably connected.
[0041] In this embodiment, the rotating handle 31 is located outside the slide rail 1 , and the end of the connecting rod 4 is located between the rotating handle 31 and the slider 21 .
[0042] In this embodiment, the outer side of the sliding member 2 is slidably matched with the slide rail 1, and the end of the slide rail 1 is symmetrically provided with oil filling holes 12, and the lubricating oil can directly enter the transverse oil groove 22 through the oil filling holes 12 to lubricate the contact surface during the sliding process.
[0043] In this embodiment, the longitudinal cross section of the slider 21 and the longitudinal cross section of the inner side of the slide rail 1 are respectively T-shaped, and the slider 21 and the slide rail 1 are slidably matched, so that the slider 21 slides along the inner side of the slide rail 1.
[0044] In this embodiment, the portion of the stop block 33 located outside the slider 21 is inserted into the slot 11 inside the slide rail 1 to improve the fixing effect after locking.
[0045] The working principle of the utility model is as follows: before use, the slide rail 1 is first fixed to the inner side of the window frame, and then the fixing frame 5 is fixed to one side of the end of the window sash through a fastener. When adjusting the opening size of the window, the shaft rod 32 is driven to rotate by rotating the handle 31, and the gear teeth at the end of the shaft rod 32 and the tooth grooves 34 on the inner side of the stop block 33 are engaged, so that the stop blocks 33 on both sides slide inward until the ends of the moving blocks 33 are separated from the card grooves 11 on the inner side of the slide rail 1, and then the sliding member 2 is driven to slide on the inner side of the slide rail 1. When the sliding member 2 moves, the stop blocks 33 on both sides are driven to slide inward. By the movable connection between the boss 24 and the end of the connecting rod 4, the connecting rod 4 drives the window sash to rotate, thereby adjusting the size of the large opening of the window sash. Since the stop block 33 will compress the spring 35 at the end when it moves inward, after the position adjustment of the window sash is completed, the spring 35 will push the stop block 33 to move outward, so that the end of the stop block 33 is reinserted into the groove 11 on the inner side of the slide rail 1 to fix the connection. The plug-in fit between the stop block 33 and the groove 11 can prevent the fixed window sash from sliding under force, thereby improving the fixing effect.
[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
