Description

Technical Field

[0001] The utility model relates to the technical field of transmission locks, in particular to an adjustable one-way transmission lock box. Background Art

[0002] Door and window lock boxes are commonly used locks on casement doors and windows. During use, the door and window lock boxes are installed on the window sash profile, and the lock point seat is installed on the window frame profile. The door and window lock boxes and the lock point seat are used together to realize the opening and closing of doors and windows. The Chinese patent with publication number CN219654479U discloses a one-way transmission lock box. In this solution, the transmission stroke is fixed and cannot be adjusted. It is only suitable for inner casement bottom-hung windows. In addition, in the process of installing the lock box on the window sash profile in this technical solution, due to the error of the installer, the locking force is too large, thereby pulling the lock box off. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an adjustable one-way transmission lock box, the transmission bar stroke of the transmission lock box can be adjusted according to the use scenario, the locking point on the transmission bar is adjustable, the transmission lock box has an anti-pull deviation function, and has a wide range of applications.

[0004] According to the first aspect of the utility model, the adjustable one-way transmission lock box includes a transmission bar and a box body arranged on the transmission bar, the box body is provided with a slide groove, and the transmission bar is slidably arranged in the slide groove. It is characterized in that notches are provided at both ends of the slide groove, and limiting parts adapted to the notches are provided at both ends of the transmission bar, and the length between the two limiting parts is longer than the length between the two notches, and a limiting block can be selectively installed in the notch.

[0005] The adjustable one-way transmission lock box according to the embodiment of the utility model has at least the following technical effects: the transmission bar can be slidably connected to the box body. In addition, the length between the two limiting parts on the transmission bar is longer than the length between the two notches on the lock box. The limiting part and the notch on the transmission bar cooperate with each other to achieve the limiting function of the sliding stroke of the transmission bar. In addition, a limiting block can be installed in the notch or not. When installed, the limiting block replaces the notch and cooperates with the limiting part to achieve the limiting function. Among them, when the door lock is used for the inward-opening casement window, the handle needs to be rotated 180 degrees, and the stroke is relatively long. Therefore, in the utility model, the notches added on both sides of the box body can increase the moving stroke of the transmission bar, so that the operation of rotating the handle 180 degrees can be satisfied, and at the same time, the cooperation between the limit part and the notch can also be used to make the transmission bar limited in movement so that it will not exceed the set stroke; on the other hand, one of the notches can be added with a limit block to make the space of the notch relatively smaller, so that one of the limit parts will directly cooperate with the limit block to achieve the limiting function of limiting the sliding stroke of the transmission bar. When it is suitable for the inward-opening bottom-hung window, the handle needs to be rotated 90 degrees. At this time, the stroke is shorter, and the utility model just uses the limit block to shorten the stroke, thereby ultimately reflecting the beneficial effects of the utility model in that the stroke is adjustable, the scope of application is wider, and the versatility is higher when in use.

[0006] According to some embodiments of the present invention, the slide groove has side walls on both sides, and the gap is located between the side walls on both sides.

[0007] According to some embodiments of the present utility model, the limiting portion is a limiting protrusion, and the width of the limiting portion is smaller than the width of the notch.

[0009] According to some embodiments of the utility model, the box body is provided with a positioning groove at the upper part of the notch, and the limiting block is provided with a positioning protrusion matched with the positioning groove.

[0010] In the above scheme, the cooperation of the positioning groove and the positioning protrusion can make the limit block be smoothly installed in the gap. Generally speaking, after the limit block is installed in the gap, the surface of the gap is basically filled. Of course, the length of the limit block can also be longer or shorter than the length of the gap, which can be specifically configured according to the actual implementation process.

[0011] According to some embodiments of the utility model, a waist-shaped stepped through groove is provided in the middle part of the limiting portion, the length direction of the waist-shaped stepped through groove is parallel to the length direction of the transmission bar, a screw is adapted to be provided in the waist-shaped stepped through groove, and the adjustable one-way transmission lock box includes a locking point seat installed on one side of the waist-shaped step through groove, a screw hole adapted to the screw is provided in the middle part of the locking point seat, a locking point is provided on one side of the locking point seat, and the screw passes through the waist-shaped step through groove and is connected with the screw hole of the locking point seat.

In this way, even if the force during installation is too large, the entire lock body will not be pulled out, and other functions of the lock body of the utility model except anti-pull-out will not be affected.

[0019] According to some embodiments of the utility model, a groove is provided on one side of the wedge-shaped plug, and a spherical convex point matching the groove is provided inside the box body.

[0020] In the above scheme, the groove and the spherical protrusion cooperate to form a snap limit, which can limit the wedge-shaped plug in the installation cavity during the assembly process and prevent it from falling out. In this way, before the utility model is installed on the window, the wedge-shaped plug is always loaded in the installation cavity during transportation and packaging.

[0021] According to some embodiments of the utility model, an elastic ring is arranged inside the box body, and the spherical convex point is installed on the elastic ring.

[0022] In the above solution, the elastic ring has a certain elasticity, so that the spherical convex points and the grooves can be more conveniently staggered with each other under the action of external force, making it convenient for the wedge-shaped plug to be installed into the installation cavity or partially slide out of the installation cavity.
