Description

Technical Field

[0001] The present invention relates to the technical field of door and window hardware components, and particularly relates to a new type of bar lock. Background Art

[0002] Hook locks are mainly anti-theft devices on door and window sashes and can be seen everywhere in our daily life. For balcony sashes or double-opening sliding windows, bar hook locks are widely used. In the prior art, the lock hook of the bar hook lock extends to one side so as to be engaged with the hook groove on the door and window frame to lock the door and window sash. When installed on the door and window sash, it is necessary to distinguish the orientation of the lock hook according to the opening and closing and pushing and pulling directions of the door and window sash; and the angle needs to be adjusted repeatedly to put the bar lock into the lock groove of the door and window sash, and the installation process is very inconvenient. Summary of the Invention

[0003] The purpose of the present invention is to provide a new type of bar lock to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] A new type of bar lock includes: a lock shell, a sliding member, a lock hook and a locking assembly;

[0006] The sliding member is slidably installed on the rear side of the lock shell in the up and down direction; the lock hook includes a connecting body and a hook body, the connecting body has a rotation axis extending in the front and rear directions, the lock hook is rotatably connected to the sliding member around the rotation axis, the hook body is arranged on one side of the connecting body, and two hook parts are arranged at one end of the hook body far from the rotation axis. On the projection plane perpendicular to the front and rear directions, the two hook parts are respectively arranged on the opposite sides of the hook body; the locking assembly is used to prevent the lock hook from rotating relative to the sliding member.

[0007] The new type of bar lock provided by the present invention has at least the following beneficial effects: the lock hook can rotate around the rotation axis. When the hook body rotates to the direction coinciding with the lock shell, the bar lock can be easily put into the lock groove, making the installation simpler and faster. After the bar lock is installed in the lock groove, the hook body can be rotated out to the left or right as needed for use, and can adapt to left-opening or right-opening door and window sashes, without the need to distinguish between left-opening and right-opening special bar locks, making production and installation more convenient. After the hook body rotates out laterally, it can be locked by the locking assembly to prevent the lock hook from rotating again, facilitating the use of the bar lock. The sliding member can move up and down relative to the lock shell, so that the hook body rotated out to the side can catch the hook part into the hook groove on the door and window frame to realize the locking action of the door and window sash.

[0008] As a further improvement of the above technical solution, a push-pull notch is provided on the front side of the lock case, and an upper push part and a lower push part arranged vertically are provided on the front side of the push-pull member. Through the above technical solution, the lock hook can be driven to move up and down by pushing the push-pull member up and down, so that the lock hook can be engaged with or disengaged from the hook groove on the door frame; when it is necessary to push the push-pull member up and down, the push-pull member can be moved up and down relative to the lock case through the upper push part and the lower push part at the push-pull notch.

[0009] As a further improvement of the above technical solution, a limiting post extending left and right is provided on the rear side of the lock case, a limiting groove extending up and down is provided on the push-pull member, the limiting post is inserted into the limiting groove, and the length dimension of the limiting groove is greater than the length dimension of the hook part. Through the above technical solution, the limiting post moves up and down in the limiting groove, providing guidance and limitation for the up and down movement of the push-pull member relative to the lock case. The length dimension of the limiting groove is greater than the length dimension of the hook part, so that the stroke of the up and down movement of the push-pull member can be greater than the size of the hook part, and the hook part can be completely engaged with or completely disengaged from the hook groove within the stroke of the push-pull member.

[0010] As a further improvement of the above technical solution, the locking assembly includes a first locking and engaging part and a second locking and engaging part that are mutually matched and engaged, and they are respectively arranged on the lock hook and the push-pull member; the number of the first locking and engaging parts is three, and the three first locking and engaging parts are circumferentially spaced apart around the rotation axis. Through the above technical solution, the lock hook and the push-pull member can be locked by the mutually matched and engaged first locking and engaging part and the second locking and engaging part, so as to achieve the effect of preventing the lock hook from rotating relative to the push-pull member. When the second locking and engaging part is respectively engaged with the three spaced-apart first locking and engaging parts, the lock hook can correspond to three rotation angles, and the hook body can be kept rotating outwards on both sides of the lock case or coinciding with the lock case.

[0011] As a further improvement of the above technical solution, the connecting body is in a plate shape, the rotation axis is arranged in the middle of the connecting body, the three first locking and engaging parts are arranged on the connecting body, and the three first locking and engaging parts and the hook body are circumferentially evenly distributed around the rotation axis; the second locking and engaging part is arranged on the push-pull member, and the second locking and engaging part is arranged above the rotation axis.

[0012] As a further improvement of the above technical solution, the push-pull member includes a push-pull block body and a sliding seat. The push-pull block body is provided with a chute extending left and right. The sliding seat is adjustably installed in the chute in the left-right direction. The locking hook is installed on the sliding seat. The first locking and clamping portion and the second locking and clamping portion are respectively arranged on the locking hook and the sliding seat. Through the above technical solution, the sliding seat can move left and right, so that the protruding length of the hook portion of the hook lock in the left-right direction can be adjusted according to the relative position of the locking groove.

[0013] As a further improvement of the above technical solution, the sliding seat is provided with a connection hole penetrating through the front and back. The connection main body is provided with a connection column coaxially arranged with the rotation axis. The connection column rotatably penetrates through the connection hole. The rear end of the connection column is fixedly connected to the connection main body. The front end of the connection column is provided with a rotation driving portion convenient for driving the connection column to rotate; the push-pull block body is provided with an avoidance hole penetrating through the front and back. The rotation driving portion coincides with the avoidance hole on the projection plane perpendicular to the front-back direction. Through the above technical solution, the locking hook can rotate relative to the sliding seat through the connection column and the connection hole, so that the hook body can rotate around the rotation axis. When screwing the locking hook, a tool corresponding to the shape of the rotation driving portion can be used to drive the locking hook to rotate.

[0014] As a further improvement of the above technical solution, the connection column axially slides through the connection hole. An elastic member is arranged between the sliding seat and the locking hook. The elastic member has a first end connected to the locking hook and making the locking hook tend to move forward relative to the sliding seat, and the elastic member has a second end connected to the push-pull member and making the push-pull member tend to move backward relative to the locking hook. Through the above technical solution, the locking hook can rotate relative to the sliding seat and move back and forth at the same time, and the elastic member can drive the locking hook to tightly abut forward. When screwing the locking hook, the locking hook is pushed backward to separate the first locking and clamping portion and the second locking and clamping portion from each other front and back so as to perform rotational adjustment; after rotating to the position, the locking hook is released, and the locking hook tightly abuts forward under the action of the elastic member so that the first locking and clamping portion and the second locking and clamping portion are clamped with each other to achieve fixation, and the operation is simple.

[0015] As a further improvement of the above technical solution, the sliding seat includes two connecting parts, which are respectively arranged on the upper and lower sides of the connecting hole. The two connecting parts are respectively in sliding contact with the upper and lower sides of the sliding groove. The front side of the connecting part is provided with an adjusting threaded hole extending backward. The push-pull block body is provided with an adjusting hole that is aligned with the adjusting threaded hole front and back. The adjusting hole is a strip-shaped hole extending in the left-right direction. By connecting the connecting screw passing through the adjusting hole with the adjusting threaded hole, the sliding seat can be locked in the sliding groove. When it is necessary to adjust the position of the sliding seat left and right, the connecting screw installed in the adjusting threaded hole can be loosened, so that the sliding seat can move left and right relative to the push-pull block body for adjustment. After adjusting to the required position, it can be locked for use.

[0016] As a further improvement of the above technical solution, the lock shell is provided with a locking operation hole penetrating through the front and back, and the locking operation hole is aligned with the locking component front and back. Through the above technical solution, when the lock hook is screwed and rotated, the operation can be performed from the locking operation hole. Brief Description of the Drawings
