[0022] Reference Figure 1-9 A sliding door and window lock includes a panel 100, a toggle bar 200, a knob 300, a limit seat 400, and a lock seat 500.

[0023] An operation groove 101 is provided on the front side of the panel 100. The internal length of the operation groove 101 is greater than the opening length, and both ends of the operation groove 101 penetrate through the top and bottom surfaces of the panel 100. A toggle bar 200 is slidably disposed within the operation groove 101 in the vertical direction. The front side of the toggle bar 200 is recessed inward, and operation surfaces 201 are formed at both ends of the sliding direction of the toggle bar 200. When the user presses the operation surface 201 through the opening of the operation groove 101, the toggle bar 200 can be pushed to slide within the operation groove 101.

[0024] A mounting hole 204 is provided on the rear side of the actuating bar 200. The mounting hole 204 passes through the actuating bar 200 along a sliding direction perpendicular to the actuating bar 200. A locking hook 600 is fixed through the mounting hole 204, and the orientation of the hook 600 can be selected according to the actual installation situation. The panel 100 is installed on the side of the door / window sash, and a lock plate 610 is installed on the door / window frame. The lock plate 610 has a lock hole 611. When the door / window sash is pushed until the locking hook 600 passes through the lock hole 611, pressing the operating surface 201 and sliding the actuating bar 200 can drive the locking hook 600 to slide upward, thereby locking the locking hook 600 onto the lock plate 610 and locking the sliding door / window. Pressing the other operating surface 201 and sliding the actuating bar 200 in the opposite direction can drive the locking hook 600 to slide downward, thereby disengaging the locking hook 600 from the lock plate 610 and unlocking the sliding door / window.

[0025] The knob 300 is rotatably connected to the toggle bar 200. The knob 300 slides as the toggle bar 200 slides. One end of the knob 300 passes through the toggle bar 200 and is positioned in the opening of the toggle bar 200 facing the operating slot 101. The knob 300 has a square structure because its length is greater than its width. The limit seat 400 is installed at the bottom of the panel 100 by screws, and a limit block 410 is provided on the top of the limit seat 400.

[0026] In the initial state, the length direction of the knob 300 is the same as the sliding direction of the knob 300. At this time, the limiting block 410 is just offset from the sliding path of the knob 300, so that the knob 300 is not restricted by the limiting block 410 and can slide smoothly with the sliding of the toggle bar 200. The toggle bar 200 is in an unlocked state.

[0027] When the actuating bar 200 slides to a position away from the limiting seat 400, such as when the actuating bar 200 slides to its uppermost position, the end of the knob 300 protruding from the surface of the actuating bar 200 is in the opening position of the operating groove 101. Rotating the knob 300 through the opening of the operating groove 101 makes the width direction of the knob 300 the same as the sliding direction of the actuating bar 200. Because the length of the knob 300 is greater than its width, the sliding path becomes wider. At this time, the limiting block 410 is located on the sliding path of the knob 300, causing the limiting block 410 to restrict the downward sliding of the knob 300, thereby restricting the downward sliding of the actuating bar 200 and achieving the locked state of the actuating bar 200. That is, when the sliding door / window is in the locked state, rotating the knob 300 can lock the lock hook 600, thereby preventing children from arbitrarily opening the sliding door / window by toggling the actuating bar 200, improving the safety of the sliding door / window.

[0028] The knob 300, with one end exposed on the toggle bar 200, has a hexagonal groove, a slotted groove, a cross groove, or other special groove structure, allowing for the design of corresponding tools to achieve the knob's rotation operation. The opening length of the operating groove 101 is shorter than the length of the panel 100. When the toggle bar 200 slides close to the limit seat 400, that is, when the toggle bar 200 slides to its lowest position, the end of the knob 300 exposed on the toggle bar 200 can be covered by the panel 100.

[0029] Furthermore, a first elastic element 420 is installed between the actuating bar 200 and the limiting seat 400. The lock seat 500 is installed on the actuating bar 200, meaning the lock seat 500 slides as the actuating bar 200 slides. A mounting post is provided at the bottom of the lock seat 500, and a mounting groove is provided at the top of the limiting seat 400. The first elastic element 420 is a first helical spring, with one end sleeved on the mounting post and the other end embedded in the mounting groove, placing the first helical spring between the lock seat 500 and the limiting seat 400. The spring force of the first helical spring pushes the lock seat 500 and the actuating bar 200 upwards, keeping the actuating bar 200 at a position away from the limiting seat 400. Correspondingly, the lock hook 600 remains engaged with the lock piece 610. By overcoming the spring force of the first helical spring and pressing the actuating bar 200 downwards, the actuating bar 200 is pushed, causing the lock hook 600 to disengage from the lock piece 610, thus unlocking the lock. On the other hand, the lock hook 600 is provided with a guide inclined surface. When the sliding door and window are closed, the lock hook 600 abuts against the lock plate 610 and moves downward against the elastic force of the first spiral spring under the action of the guide inclined surface. After the lock hook 600 is inserted into the lock plate 610, it automatically latches onto the lock plate 610 under the action of the elastic restoring force of the first spiral spring, thereby realizing the automatic locking of the sliding door and window.

[0030] In other embodiments, the first elastic element 420 may be omitted. When the sliding direction of the toggle bar 200 is horizontal, the toggle bar 200 can remain at any position in the operating groove 101 without external force. Alternatively, when the sliding direction of the toggle bar 200 is vertical or inclined, the maximum static friction between the toggle bar 200 and the panel 100 may be greater than the overall weight of the toggle bar 200 and other sliding components, allowing the toggle bar 200 to remain at any position in the operating groove 101 without external force. In other embodiments, the locking seat 500 may be omitted, and instead, the first elastic element may be connected between the toggle bar 200 and the limiting seat 400.

[0031] Furthermore, the vertical portion of the lock base 500 and the horizontal portion located at the bottom of the vertical portion give the lock base 500 an inverted T-shaped cross-section. A receiving groove 202 is provided at the bottom of the actuating bar 200, with the actuating bar 200 extending through both sides of the receiving groove 202. The horizontal portion of the lock base 500 abuts against the bottom of the actuating bar 200, and the vertical portion of the lock base 500 extends into the receiving groove 202. The knob 300 is rotatably connected to the vertical portion of the lock base 500. The actuating bar 200 has a clearance hole 203, which communicates with the receiving groove 202, allowing one end of the knob 300 to pass through the clearance hole 203 and protrude from the surface of the actuating bar 200, exposing itself at the opening of the operating groove 101, facilitating rotation of the knob 300.

[0032] Two positioning blocks 530 are provided on the side of the lock base 500 facing the knob 300. The side of the positioning blocks 530 facing the knob 300 has an arc surface. A positioning groove 540 is provided on the side of the knob 300 facing the lock base 500. The two positioning blocks 530 are respectively positioned in two positions where the knob 300 is in the same direction of length and sliding and in the same direction of width and sliding, corresponding to and embedded in the positioning groove 540, thereby positioning the knob 300 in two states. It should be noted that two positioning grooves 540 can also be provided on the side of the knob 300 facing the lock base 500, with the two positioning grooves 540 distributed at both ends of the length direction of the knob 300. In this embodiment, four positioning grooves 540 are provided on the side of the knob 300 facing the lock base 500, with two positioning grooves 540 distributed at both ends of the length direction of the knob 300 and the other two positioning grooves 540 distributed at both ends of the width direction of the knob 300.

[0033] Furthermore, a first slide bar 210 is provided on the side wall of the receiving groove 202. The first slide bar 210 is integrally formed with the actuating bar 200, and the length direction of the first slide bar 210 is perpendicular to the sliding direction of the actuating bar 200. A first sliding groove 220 is provided on one side of the lock seat 500, and the first sliding groove 220 is adapted to slide with the first slide bar 210. When the first slide bar 210 is slid into the first sliding groove 220, the horizontal part of the lock seat 500 also abuts against the end of the actuating bar 200, so that the lock seat 500 and the actuating bar 200 are connected, and the lock seat 500 can slide along with the sliding of the actuating bar 200. The structure is simple and easy to assemble. In other embodiments, the first sliding groove 220 may be provided on the side wall of the receiving groove 202, and the first slide bar 210 may be provided on one side of the lock seat 500, and the first slide bar 210 is integrally formed with the lock seat 500.

[0034] Furthermore, a second slide bar 230 is provided at the bottom end of the actuating bar 200, and the second slide bar 230 is integrally formed with the actuating bar 200. The second slide bar 230 is parallel to the first slide bar 210, and the lock seat 500 is provided with a second sliding groove 240, which is adapted to slide with the second slide bar 230. When the first slide bar 210 slides into the first sliding groove 220, the second slide bar 230 also slides into the second sliding groove 240, thereby stabilizing the connection between the lock seat 500 and the actuating bar 200. In other embodiments, the receiving groove 202 may only penetrate one side of the actuating bar 200, and the lock seat 500 slides into or out of the actuating bar 200 on this penetrating side.

[0035] In other embodiments, the lock base 500 may also be connected to the toggle bar 200 by means of screws or glue.

[0036] In this embodiment, a protrusion 510 is provided on the side of the lock base 500 near the knob 300, and the protrusion 510 is integrally formed with the lock base 500. The limiting block 410 is provided with a groove 520, the top of which passes through the limiting block 410 to allow the protrusion 510 to slide into it. When the lock base 500 slides with the toggle bar 200, the protrusion 510 slides on the groove 520, and the bottom side of the groove 520 can serve as a limiting position for the sliding of the protrusion 510, thereby limiting the sliding limit position of the toggle bar 200.

[0037] In this embodiment, two limiting blocks 410 are provided, respectively distributed on the left and right sides of the horizontal portion of the lock base 500, that is, the two limiting blocks 410 are located on both sides of the knob 300. The distance between the two limiting blocks 410 is greater than the width of the knob 300, and at the same time, the distance between the two limiting blocks 410 is less than the length of the knob 300. That is, when the knob 300 is rotated to the point where the length direction is the same as the sliding direction, the knob 300 can slide between the two limiting blocks 410 without being restricted by the two limiting blocks 410. However, when the knob 300 is rotated to the point where the width direction is the same as the sliding direction, the length of the knob 300 is greater than the distance between the two limiting blocks 410 and cannot slide between the two limiting blocks 410. The knob 300 is simultaneously restricted by the two limiting blocks 410 and cannot slide, thereby restricting the sliding of the toggle bar 200. In other embodiments, the limiting base 400 may also be provided with only one limiting block 410.

[0038] The knob 300 has an arc-shaped convex surface 310 on its outer periphery, distributed on both ends of the knob 300 along its length. The top of the two limiting blocks 410, on their adjacent sides, has an arc-shaped concave surface 320. The concave surface 320 matches the arc-shaped convex surface 310, allowing the arc-shaped convex surface 310 to engage or approach the arc-shaped concave surface 320 during knob rotation. When the knob 300 is rotated until its width direction is the same as its sliding direction, the limiting block 410 immediately restricts the sliding of the knob 300, thus preventing the toggle bar 200 from sliding relative to the panel 100 during locking, improving the stability and reliability of the locked state.

[0039] In this embodiment, a slider seat 110 and a slider fork 120 are provided at the top of the panel 100. The slider seat 110 is fixedly installed at the top of the panel 100 by screws, and the slider fork 120 is slidably connected to the panel 100. An inner groove 111 is provided between the slider seat 110 and the inner wall of the operation groove 101 of the panel 100, and the top of the toggle bar 200 is slidably disposed in the inner groove 111. The slider fork 120 is located at the top of the slider seat 110, and a second elastic element 130 is installed between the slider seat 110 and the slider fork 120. The second elastic element 130 is a second helical spring, one end of which is installed on the slider seat 110, and the other end is installed on the slider fork 120. The elastic force of the second helical spring can push the top of the slider fork 120 to extend out of the top of the panel 100. A triangular block 140 is provided at the top of the slider fork 120, and the triangular block 140 is integrally formed with the slider fork 120.

[0040] When installing a sliding door / window lock on a sliding door / window, the bottom of the panel 100 is inserted into the pre-cut groove. When the top of the panel 100 is pressed against the top of the groove, the sliding block 140 can push the slider fork 120 to overcome the elastic force of the second spiral spring and retract into the panel 100. After the top of the panel 100 is embedded in the groove, the triangular block 140 of the slider fork 120 extends into the groove, thereby stabilizing the position of the panel 100 and facilitating the installation of the panel 100.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
