Technical Field

[0001] The utility model belongs to the field of window hinges, and particularly relates to a sliding block for locking a sliding support arm and a hinge using the sliding block. Background Art

[0002] A sliding arm is often provided in a window hinge, and the sliding of the sliding arm is used to drive other connecting rods to realize the opening and closing of the hinge. The sliding of the sliding arm is usually realized by sliding a slider along a frame fixing plate. The existing slider only has a sliding function. If a child accidentally operates the window and opens the hinge to open the window sash, it is easy to cause a risk of falling. Therefore, a slider with a locking function is needed to ensure that the window sash can only be opened at a safe angle to improve safety assurance. Utility Model Content

[0003] The utility model aims to provide a child lock slider, which has the functions of locking and unlocking.

[0004] The child lock slider comprises a slide seat, the slide seat is provided with a communicating transverse hole and a longitudinal hole, the longitudinal hole is provided with a driving member, the transverse hole is provided with a locking member, and the driving member can drive the locking member to move along both sides of the slide seat.

[0005] The driving member is a screw, and the longitudinal hole is a screw hole.

[0006] The locking member is a locking ball, and the screw abuts against the locking ball via a transmission ball.

[0007] There are two locking balls, an insert is provided at the bottom of the slide seat, and transverse holes are provided on both sides of the insert, and the locking balls are correspondingly installed in the transverse holes.

[0008] One end of the sliding seat is provided with a step.

[0009] The other end of the slide is provided with a roller which rolls along the width direction of the slide.

[0010] The hinge includes a child lock slider, a window frame fixing plate, a window sash fixing plate and a connecting rod mechanism. The window frame fixing plate and the window sash fixing plate are rotatably connected through the connecting rod mechanism. The sliding end of the connecting rod mechanism is installed on a sliding seat. The window frame fixing plate is provided with a sliding groove along its length direction, and the sliding seat is installed in the sliding groove.

[0011] The connecting rod mechanism includes a first support arm, a second support arm and a sliding arm, one end of the first support arm and one end of the second support arm are both rotatably connected to the window frame fixing plate, the other end of the first support arm is rotatably connected to one end of the window sash fixing plate, the other end of the second support arm is rotatably connected to the middle part of the sliding arm, the second support arm is arranged between the first support arm and the sliding arm, one end of the sliding arm is slidably and rotatably connected to the sliding seat, and the other end of the sliding arm is rotatably connected to the middle part of the window sash fixing plate.

[0012] The window frame fixing plate is provided with a wind-resistant pressure block, and the wind-resistant pressure block is limited to the first support arm and the second support arm along the width direction and the length direction of the window frame fixing plate.

[0013] The utility model has the beneficial effect that the slider drives the driving roller to squeeze the locking roller by tightening the screw, and the locking roller presses the slide groove along the lateral sides, so as to achieve the purpose of locking the slider to the slide groove. Therefore, the slider is applied to the hinge, and the hinge can be locked when it is opened to a certain safety angle, thereby preventing the danger caused by children's misoperation. At the same time, the roller provides rolling support for the window sash when the window sash is closed, thereby preventing the window sash from falling to one end.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 , 2 As shown, the child lock slider A includes a slide 8, and the slide 8 is provided with a connected transverse hole 9 and a longitudinal hole 10. The longitudinal hole 10 is installed with a driving member, and the transverse hole 9 is installed with a locking member. The driving member can drive the locking member to move along both sides of the slide. The driving member is a screw 11, and the longitudinal hole 10 is a screw hole. The locking member is a locking ball 13, and the screw 11 abuts against the locking ball 13 through a transmission ball 14. There are two locking balls 13, and an insert 15 is provided at the bottom of the slide 8. Both sides of the insert 15 are provided with transverse holes 9, and the locking balls 13 are correspondingly installed in the transverse holes 9. A step 12 is provided at one end of the slide 8. A roller 16 that rolls along the width direction of the slide 8 is provided at the other end of the slide 8.

[0019] like Figure 1 , 2As shown in Figures 3, the hinge includes a child lock slider A, a window frame fixing plate 1, a first support arm 2, a second support arm 3, a sliding arm 4 and a window sash fixing plate 5. The first support arm 2, the second support arm 3 and the sliding arm 4 form a connecting rod mechanism. One end of the first support arm 2 and one end of the second support arm 3 are both rotatably connected to the window frame fixing plate 1. An anti-wind pressure block 6 is installed between one end of the first support arm 2 and one end of the second support arm 3. The anti-wind pressure block is limited to the first support arm and the second support arm along the width direction and the length direction of the window frame fixing plate. The other end of a support arm 2 is rotatably connected to one end of a window sash fixing plate 5, the other end of a second support arm 3 is rotatably connected to the middle of a sliding arm 4, the second support arm 3 is arranged between the first support arm 2 and the sliding arm 4, one end of the window frame fixing plate 1 is provided with a slide groove 7 along the length direction of the window frame fixing plate 1, one end of the sliding arm 4 is rotatably connected to a step 12, the upper surface of the slide groove 7 is installed along the bottom of a slide seat 8, an insert 15 is embedded in the slide groove 7, a bottom plate is installed on the lower surface of the slide groove 7, and the bottom plate is fixedly connected to the slide seat 8 with screws. The other end of the sliding arm 4 is rotatably connected to the middle of the window sash fixing plate 5. The above-mentioned rotational connection is preferably connected by rivets.
