Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a hook lock structure, hook lock assembly, and door and window system. Background Technology

[0002] Existing door locks, especially those for sliding doors and windows, generally only have one locking hook. This hook extends and engages with the lock seat to lock the window sash to the door frame. However, a single locking hook has fewer locking points and weaker locking force, resulting in poor stability of the connection between the window sash and the door frame.

[0003] To improve the connection stability between the window sash and the door frame, the door lock in related technologies is equipped with two locking hooks. The two locking hooks extend simultaneously under the action of a transmission mechanism. After the two locking hooks extend, they cooperate with the lock seat to lock the window sash and the door frame. This transmission mechanism often adopts a gear and rack mechanism or a parallel linkage mechanism. The synchronous extension and retraction of the two locking hooks are achieved by the rotation of the gear or linkage. However, both gear and rack mechanisms and parallel linkage mechanisms are relatively complex and occupy a large space, which leads to the door sash itself needing to be made larger, affecting the lighting and view of the door and window. Utility Model Content

[0066] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0067] Example 1

[0068] Please see Figures 1 to 9 This application provides a hook lock structure, including: a hook lock component 10; a first fixing component 20, the hook lock component 10 being rotatably connected to the first fixing component 20; a transmission component 30, the transmission component 30 being slidably connected to the first fixing component 20, the transmission component 30 being provided with a transmission pin 40, each hook lock component 10 being provided with a first guide hole 101, the transmission pin 40 being correspondingly provided with the first guide hole 101, and the transmission pin 40 being tractively connected to the first guide hole 101; an elastic component 50, the elastic component 50 being disposed between two hook lock components 10, the two ends of the elastic component 50 being respectively abutting against the two hook lock components 10; the transmission component 30 sliding along a first direction to drive the two hook lock components 10 to rotate out, and the transmission component 30 sliding along a second direction to drive the two hook lock components 10 to rotate back.

[0069] The hook-lock structure in this utility model is connected to the first guide hole 101 via a transmission pin 40. In use, the transmission member 30 slides along the first direction to drive the two hook-lock members 10 to rotate out, and the transmission member 30 slides along the second direction to drive the two hook-lock members 10 to rotate back. Furthermore, the elastic member 50 is placed between the two hook-lock members 10 to provide positioning force for the hook-lock members 10. The overall structure is simple, the connection is stable, and it occupies less space.

[0070] It should be noted that the first direction and the second direction are two opposite directions. For example, the first direction and the second direction are directions parallel to the axis of the transmission component 30.

[0071] In this embodiment of the utility model, the transmission component 30 includes a transmission bar 301 and a push frame 302, the transmission bar 301 and the push frame 302 being connected to each other as a whole; the push frame 302 includes a first push body 3021 and a second push body 3022, the first push body 3021 and the second push body 3022 being connected to each other as a whole; two hook locks 10 are both disposed in the space between the first push body 3021 and the second push body 3022, and a transmission pin 40 passes through the first push body 3021 and the second push body 3022.

[0072] Since the elastic element 50 is disposed between the two hook-locking parts 10, both the hook-locking parts 10 and the elastic element 50 are disposed between the first pusher 3021 and the second pusher 3022. The first pusher 3021 and the second pusher 3022 limit both sides of the hook-locking parts 10 and both sides of the elastic element 50, thereby improving the stability of the hook-locking parts 10 when they turn out and turn back, and preventing the hook-locking parts 10 from shaking when they rotate.

[0073] Specifically, in order for the transmission component 30 to perform transmission, the transmission bar 301, the first pusher 3021, the second pusher 3022 and the transmission pin 40 can be connected and fixed into an integral structure. The transmission pin 40 can be connected and fixed to at least one of the first pusher 3021 and the second pusher 3022. The integral structure slides together, and during the sliding process of the integral structure, the transmission pin 40 slides along the corresponding first guide hole 101, thereby driving the corresponding hook lock component 10 to rotate relative to the first fixed component 20.

[0074] Specifically, the first pusher 3021 and the second pusher 3022 can be integrally formed or separately manufactured and then connected into one unit by welding, snap-fitting, bonding or other methods. The transmission bar 301 and the pusher frame 302 can be integrally formed or separately manufactured and then connected into one unit by welding, snap-fitting, bonding or other methods.

[0075] In this embodiment of the utility model, the first fixing member 20 includes a fixing frame 201, the fixing frame 201 includes a first fixing body 2011 and a second fixing body 2012, the first fixing body 2011 and the second fixing body 2012 are connected to each other as a whole; the push frame 302 provides a space between the first fixing body 2011 and the second fixing body 2012, and a rotating shaft 60 passes through the first fixing body 2011 and the second fixing body 2012, and the hook locking member 10 is rotatably connected to the first fixing member 20 through the rotating shaft 60.

[0076] Specifically, the rotating shaft 60 can be connected and fixed to at least one of the first fixing body 2011 and the second fixing body 2012.

[0077] Since the push frame 302 is positioned between the first fixed body 2011 and the second fixed body 2012, the first fixed body 2011 and the second fixed body 2012 limit both sides of the push frame 302, thereby improving the stability of the push frame 302 sliding along the first direction and along the second direction, thus achieving directional sliding.

[0078] Specifically, the first fixing body 2011 and the second fixing body 2012 can be integrally formed or separately manufactured and then connected into one piece by welding, snap-fitting, bonding or other methods.

[0079] In this embodiment of the utility model, the first fixing member 20 includes a cover 202, which is connected to the fixing frame 201 as a whole, and the cover 202 is provided with a connecting hole 203 for the hook lock member 10 to extend out.

[0080] Specifically, the fixing frame 201 and the cover 202 can be integrally formed or made separately and then connected into one piece by welding, snap-fitting, bonding or other methods.

[0081] In this embodiment of the utility model, a second guide hole 303 is provided on the transmission bar 301, and a guide portion 204 for sliding connection with the second guide hole 303 is provided on the first fixing member 20; a third guide hole 304 is provided on the push frame 302, and the third guide hole 304 is connected to the rotating shaft 60 in a transmission manner; the second guide hole 303 and the third guide hole 304 are arranged parallel to each other.

[0082] Specifically, during the sliding process of the integrated structure formed by the transmission bar 301, the first pusher 3021, the second pusher 3022 and the transmission pin 40, the transmission pin 40 slides along the corresponding first guide hole 101 and the third guide hole 304 slides along the rotating shaft 60, thereby driving the corresponding hook lock 10 to rotate relative to the first fixing member 20.

[0083] It should be noted that the extension direction of the second guide hole 303 and the extension direction of the third guide hole 304 are both parallel to the axial direction of the transmission component 30.

[0084] In this embodiment of the utility model, the hook lock member 10 includes a main body 102 and a hook portion 103, and the main body 102 and the hook portion 103 are connected to each other; at least one of the two hook lock members 10 has a first pushing recess 104, a pushing protrusion 105 and a second pushing recess 106 sequentially arranged on the edge of the main body 102; when the hook lock member 10 is in the rotated state, the elastic member 50 abuts against the first pushing recess 104, and when the hook lock member 10 is in the rotating state, the elastic member 50 abuts against the second pushing recess 106.

[0085] Specifically, the hook portions 103 of the two hook lock parts 10 are arranged opposite each other, so that the two hook lock parts 10 can be engaged with the lock seat structure described below after they are rotated out.

[0086] It should be noted that the edges of one of the two hook lock parts 10 main bodies 102 are sequentially provided with a first push recess 104, a push protrusion 105 and a second push recess 106, or the edges of both main bodies 102 are sequentially provided with a first push recess 104, a push protrusion 105 and a second push recess 106.

[0087] See Figure 3 When the hook lock 10 is in the rotated-out state, the elastic element 50 abuts against the first push recess 104. Under the elastic force of the elastic element 50, the hook lock 10 tends to rotate towards the other hook lock 10. Due to the limiting effect of the elastic element 50, the hook lock 10 maintains a relatively stable rotated-out state.

[0088] See Figure 6 When the hook lock 10 is in the rotating state, the elastic element 50 abuts against the second push recess 106. Under the elastic force of the elastic element 50, the hook lock 10 tends to rotate away from the other hook lock 10. Due to the limiting effect of the fixing frame 201, the hook lock 10 maintains a relatively stable rotating state.

[0089] Specifically, the main body 102 and the hook 103 can be integrally formed or made separately and then connected into one piece by welding, snap-fitting, bonding or other methods.

[0090] In this embodiment of the present invention, the setting direction of the first guide hole 101 on one hook lock member 10 and the setting direction of the first guide hole 101 on another hook lock member 10 are at an angle β.

[0091] Specifically, see Figure 3 as well as Figure 6 The first guide holes 101 on both hook lock parts 10 are inclined. Since there is an included angle β between the setting directions of the two first guide holes 101, it can be seen that the first guide holes 101 on the two hook lock parts 10 are inclined in different directions.

[0092] See Figure 13In use, to facilitate the storage of the hook lock 10, when the hook lock 10 is in the rotating state, the hook lock 10 is parallel to the first fixing member 20; to facilitate the engagement of the hook lock 10 with the lock seat structure described below, when the hook lock 10 is in the rotating out state, the hook lock 10 is perpendicular to the first fixing member 20; thus, when the transmission member 30 drives the two hook locks 10 to rotate from the rotating state to the rotating out state, both hook locks 10 rotate 90°. For example, when the two hook locks 10 rotate synchronously from the vertical state to the horizontal state, the included angle β is 90°.

[0093] In this embodiment of the utility model, the elastic element 50 includes a first positioning body 501, a second positioning body 502 and an elastic body 503. The first positioning body 501 is sleeved on one end of the elastic body 503, and the second positioning body 502 is sleeved on the other end of the elastic body 503.

[0094] Specifically, the elastomer 503 is a spring, a silicone pillar, or a rubber pillar.

[0095] In order to achieve directional expansion and contraction of the elastic body 503, the first positioning body 501 and the second positioning body 502 are nested and slidably connected. One end of the elastic body 503 is fixedly connected to the first positioning body 501, and the other end of the elastic body 503 is fixedly connected to the second positioning body 502.

[0096] Example 2

[0097] Please see Figures 10 to 12 This application provides a hook lock assembly, including the hook lock structure described above, and also includes a lock seat structure. The lock seat structure includes a second fixing member 70, a movable member 80, and an adjusting member 90. The movable member 80 is provided with a snap-fit ​​hole 100 for engaging with the hook lock member 10. The adjusting member 90 passes through between the second fixing member 70 and the movable member 80, and the distance between the second fixing member 70 and the movable member 80 is adjusted by rotating the adjusting member 90.

[0098] The hook-lock assembly of this utility model is configured with a lock seat structure that cooperates with the hook-lock structure. By rotating the adjusting member 90, the distance between the second fixed member 70 and the movable member 80 can be adjusted, thereby adjusting the tightness of the cooperation between the lock seat structure and the hook-lock structure.

[0099] Specifically, one end of the adjusting member 90 has an adjusting thread, and the other end of the adjusting member 90 is a smooth rod structure. The movable member 80 is provided with a threaded hole for threaded connection with the adjusting member 90, and the second fixed member 70 is provided with a mounting hole for rotatable connection with the adjusting member 90. The movable member 80 is embedded inside the second fixed member 70 and is slidably connected to the second fixed member 70. By rotating the adjusting member 90 in the forward direction, the movable member 80 is driven to slide closer to the second fixed member 70. By rotating the adjusting member 90 in the reverse direction, the movable member 80 is driven to slide away from the second fixed member 70, thereby adjusting the distance between the second fixed member 70 and the movable member 80.

[0100] It should be noted that the forward rotation is clockwise and the reverse rotation is counterclockwise; or the forward rotation is counterclockwise and the reverse rotation is clockwise.

[0101] To prevent the adjusting member 90 from falling off, the adjusting member 90 is inserted into the movable member 80 and the second fixed member 70 and then secured with a shim.

[0102] Specifically, the second fixing part 70 can be a base, the movable part 80 can be a buckle plate, and the adjusting part 90 can be an adjusting screw.

[0105] The door and window system of this utility model includes the above-mentioned hook and lock assembly, which has a stable connection. The tightness of the lock seat structure and the hook and lock structure in the hook and lock assembly is adjustable. Furthermore, the hook and lock structure occupies less space and has less impact on the lighting and view of the door and window system.

[0106] Specifically, the first fixing member 20 of the hook lock structure is connected and fixed to the window sash 110 by means of screw connection, welding, bonding, etc., and the second fixing member 70 of the lock seat structure is connected and fixed to the window frame 120 by means of screw connection, welding, bonding, etc.
