Technical Field
[0001] The utility model relates to the technical field of door and window accessories, in particular to a lock seat with adjustable bottom height. Background Art
[0002] When the window sash is open, it is usually hung on the door frame on one side through hinges and other structures. If the window sash is opened for a long time, it is easy for the window sash to shift downward due to gravity, causing the window sash to be positioned below the correct closing position when closing the window sash, which may affect the normal closing of the window sash and other daily uses. Utility Model Content
[0003] The purpose of the present utility model is to provide a bottom-adjustable height lock seat 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 is: a bottom-adjustable height lock seat, used to limit the locking point, the lock seat includes: a base, provided with a threaded hole and a lock groove for the locking point to be embedded from top to bottom, and a notch is provided on the front side of the lock groove; an adjusting slider, rotatably installed with an adjusting screw that can be screwed into the threaded hole, when the adjusting screw rotates in the threaded hole, the adjusting slider moves up and down relative to the base, and the top of the adjusting slider is provided with an adjusting surface for limiting the locking point.
[0005] This technical solution has at least the following beneficial effects: the base is mounted on the door frame, and the locking point is slidably arranged on the door and window sashes. After closing the door and window sashes, when the locking point is locked downward, the locking point is embedded in the lock groove and contacts or is close to the adjustment surface of the adjustment slider. The locking point is restricted by the side wall of the lock groove to achieve locking of the door and window sashes. When the door and window sashes deviate downward, the adjustment screw can be rotated to fine-tune the adjustment slider relative to the base. When the locking point is embedded in the lock groove, it contacts the adjustment surface of the adjustment slider before reaching the original locking position, thereby lifting the door and window sashes and balancing the original downward deviation, so that the door and window sashes can be corrected to the correct position. The position adjustment gradient of the adjustment slider is small, which can achieve fine-tuning and prevent the door and window sashes from being over-corrected. There is no need to readjust the position of the base on the door frame, ensuring that the door and window sashes are efficiently and conveniently adjusted to the correct or appropriate position.
[0006] As a further improvement of the above technical solution, the adjusting slider is slidably arranged in the locking slot, which can improve the sliding stability of the adjusting slider and improve the utilization rate of the internal space of the locking slot, making the overall structure more concise and compact.
[0007] As a further improvement of the above technical solution, the threaded hole is arranged on the bottom wall of the lock slot, making full use of the internal space of the lock slot and making the overall structure more concise and compact.
[0008] As a further improvement to the above technical solution, a limiting ridge is formed around the side wall of the adjusting screw, and a limiting groove is formed on the side wall of the adjusting slider. The limiting ridge can be inserted into the limiting groove along the diameter of the adjusting screw and rotate relative to the side wall of the limiting groove. This simplifies the structure of the adjusting slider for mounting the adjusting screw and facilitates assembly of the adjusting slider and the adjusting screw.
[0009] As a further improvement to the above technical solution, the limiting flange is provided on the top of the adjusting screw, and the top of the adjusting screw is provided with a tool slot for inserting a rotating tool. The adjusting screw can be a conventional screw such as a cylindrical head screw or a flat head screw, which can reduce manufacturing costs.
[0010] As a further improvement to the above technical solution, a protruding block is provided on the rear side of the adjustment slider, a sliding groove is provided in the locking slot for the protruding block to slide, and the protruding block and the adjustment slider are both provided with a clearance hole corresponding to the tool slot. This increases the operable space within the locking slot, making it easier for a tool to pass through the clearance hole to rotate the adjustment screw.
[0011] As a further improvement to the above technical solution, the front side of the adjusting slider is flush with the front side of the base, and the adjusting surface is located in the notch, thereby expanding the space available for setting the clearance hole and facilitating the rotation of the adjusting screw.
[0012] As a further improvement to the above technical solution, a through slot is formed on one side of the base, forming a mounting edge at the rear of one side of the base. A set screw extending to the rear of the other side of the base is screwed in obliquely through the front of one side of the base, and the set screw is located below the lock slot 220. The mounting edge on one side is first embedded in one side of the groove of the door or window frame, and then the set screw is screwed in so that the end of the set screw contacts the other side of the groove. This allows the lock base to be securely mounted on the door or window frame, and also allows for significant adjustment of the lock base's mounting position.
[0013] As a further improvement to the above technical solution, an abutment block extends from the bottom of the adjustment slider, with the bottom of the abutment block contacting the front sidewall of the base. When the locking point contacts the adjustment surface at the top of the adjustment slider, the outer sidewall of the base provides support for the abutment block, balancing the downward force of the locking point on the adjustment slider and ensuring the stability of the adjustment slider.
[0014] As a further improvement of the above technical solution, the base is provided with anti-skid patterns in the range of the abutment block, which not only prevents the adjustment slider from sliding down, but also serves as a mark of the adjustable range of the adjustment slider.

Therefore, they cannot be understood as limitations on the present invention.
[0027] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.
[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0029] Generally, a lock seat is installed on the inner side of the door and window frame, and a transmission rod that slides by a handle operation is provided on the side of the door and window sash. The transmission rod can drive the lock point assembly 110 to move, thereby driving the lock point 100 on the lock point assembly 110 to embed into the lock seat, so that the lock seat can limit the lock point 100, thereby limiting the door and window sash and realizing the locking of the door and window sash.
[0030] Reference Figure 1-7 The bottom-adjustable height lock base includes a base 200 and an adjustment slider 300. A lock slot 220 is defined at the top of the base 200. A notch 221 is formed on the front side of the lock slot 220, extending through the front side of the base 200. The notch 221 is the same length as the lock slot 220, and its width is smaller than the width of the lock slot 220, resulting in a T-shaped cross-section of the lock slot 220 and the notch 221. The locking point 100 is a columnar structure with a T-shaped cross-section. The lock base is mounted on the inside of the door or window frame, and the lock point 100 is positioned on the side of the door or window sash via the lock point assembly 110. When the door or window is closed and locked, the handle causes the lock point assembly 110 to move the lock point 100 downward, embedding it in the lock slot 220 of the base. The sidewalls of the lock slot 220 and / or the sidewalls of the notch 221 serve as locking surfaces to constrain the lock point 100, thereby achieving the desired locking effect.
[0031] The outer shape of the adjustment slider 300 matches the interior space of the locking slot 220, allowing the adjustment slider 300 to be inserted into the locking slot 220 through the top opening of the locking slot 220, allowing the adjustment slider 300 to slide stably up and down within the locking slot 220. A bump 320 is integrally formed on the rear side of the adjustment slider 300. The bump 320 is thinner in the vertical direction than the adjustment slider 300 itself. A slide groove 330 is defined on the rear sidewall of the locking slot 220, and its length is the same as that of the locking slot 220. As the adjustment slider 300 slides up and down within the locking slot 220, the bump 320 also slides up and down within the slide groove 330, ensuring the sliding stability of the adjustment slider 300.
[0032] The front side of the adjustment slider 300 is flush with the front side of the base 200. An upwardly projecting adjustment surface 310 is formed at the top of the adjustment slider 300, located at the position of the notch 221. This surface 310 is U-shaped, with the opening facing upward. When the locking point 100 is inserted into the locking slot 220, the locking point 100 can contact the adjustment surface 310 or be in a position close to contacting the adjustment surface 310.
[0033] A threaded hole 210 is vertically formed at the bottom of the lower portion of the locking slot 220. An adjusting screw 400 is rotatably mounted on the adjusting slider 300. The adjusting screw 400 can be screwed into the threaded hole 210, thereby securing the adjusting slider 300 at a desired height. By rotating the adjusting screw 400 to change the depth of the screw 400 inserted into the threaded hole 210 or the height of the screw 400 removed from the threaded hole 210, the height position of the adjusting slider 300 can be changed, thereby limiting the locking point 100. If the door or window sash deviates downward during use, the adjusting screw 400 can be rotated to adjust the adjusting slider 300 upward to a certain height. This allows the locking point 100 of the door or window sash to contact the adjusting surface 310 during the process of falling and locking, thereby raising the door or window sash to a certain height, thereby correcting the door or window sash to the correct position and resolving the downward deviation. There is no need to change the position of the base 200 installed on the door and window frame. The adjustment operation is convenient and quick, and the height of the adjustment slider 300 can be fine-tuned. The adjusted adjustment slider 300 can also ensure its own stability and ensure the normal use of the door and window sashes.
[0034] In addition, the setting of the slide groove 330 can make the bottom area of the locking groove 220 larger, and the size of the threaded hole 210 can be set larger to ensure the stability of the connection between the adjusting screw 400 and the base 200, thereby further ensuring the stability of the adjusting slider 300.
[0035] In other embodiments, the adjustment slider 300 can also be slidably disposed on the front side of the base 200 or at the position of the notch 221. The base 200 can be provided with a platform on the outside with a threaded hole formed on the top of the platform. The bottom of the adjustment slider 300 is rotatably connected to the adjustment screw 400, which is screwed into the threaded hole. The height of the adjustment slider 300 can also be easily changed by rotating the adjustment screw 400.
[0036] The top of the adjusting screw 400 is surrounded by a retaining flange 410, and a tool slot 430 is defined on the top surface of the adjusting screw 400. The tool slot 430 is a hexagonal socket, facilitating the use of an hexagonal wrench to turn the adjusting screw 400. In other embodiments, the tool slot 430 may alternatively be a cross slot, a slotted slot, or other slot configurations that facilitate the use of a tool to turn the adjusting screw 400. A retaining groove 420 is defined on the rear side of the adjusting slider 300. The retaining groove 420 is semicircular in shape, adapted to fit the retaining flange 410. The top side of the retaining groove 420 is flush with the bottom side of the protrusion 320. The retaining flange 410 of the adjusting screw 400 can be inserted into the retaining groove 420 from the rear, i.e., in the diametrical direction. As the adjusting screw 400 rotates, the retaining flange 410 can rotate relative to the sidewalls of the retaining groove 420. A clearance hole 340 is provided between the protrusion 320 and the adjusting slider 300 . The position of the clearance hole 340 corresponds to the position of the tool slot 430 , so that a tool can pass through the clearance hole 340 and be inserted into the tool slot 430 to rotate the adjusting screw 400 .
[0037] When installing the adjusting slider 300, the limiting convex edge 410 of the adjusting screw 400 can be embedded in the limiting groove 420, and then the adjusting slider 300 can be embedded in the locking groove 220. A tool is used to pass through the clearance hole 340 and be embedded in the tool groove 430 to rotate the adjusting screw 400, thereby facilitating the assembly between the adjusting screw 400 and the adjusting slider 300. The structure of the adjusting slider 300 is simple, easy to manufacture, and reduces production costs.
[0038] In other embodiments, the connection between the adjusting screw 400 and the adjusting slider 300 can also be achieved by providing a countersunk hole in the protrusion. After the adjusting screw 400 passes through the countersunk hole, the limiting flange 410 is embedded in the countersunk hole and then a limiting ring that can limit the limiting flange 410 is installed or fixed. The adjusting screw 400 can also be rotated relative to the adjusting slider 300, and when the adjusting screw 400 is rotated, the adjusting slider 300 can be driven to move up and down to adjust the height.
[0039] The left side of the base 200 is provided with a through slot 500 extending vertically, forming a mounting edge 510 at the rear portion of the left side of the base 200. A set screw 520 is screwed in at an angle at the front portion of the left side of the base 200. One end of the tilted set screw 520 passes through the base 200 and reaches the rear portion of the right side of the base 200. The door and window frame profile is provided with a profile slot. The mounting edge 510 is first inserted into one side of the profile slot, and then the set screw 520 is screwed in so that it abuts the other side of the profile slot, thereby enabling the lock seat to be installed. This installation method has the advantage of allowing the lock seat to be arbitrarily adjusted in its installation position, which is highly flexible. However, the accuracy of the adjustment position is difficult to control. Therefore, the height of the adjustment surface 310 is fine-tuned by rotating the adjustment screw 400, thereby ensuring the accuracy of the position of the adjustment slider 300 and resolving the problem of the door and window sash being tilted downward.
[0040] The set screw 520 is located below the locking slot 220, so the setting of the slide slot 330 can occupy the position on the rear side of the base 200, or in other words, the setting of the through slot 500 and the base 200 will not increase the thickness of the base 200 too much, thereby achieving the adjustability of the base 200 while reducing the thickness of the base 200 as much as possible to achieve a light and thin effect.
[0041] An interference block 600 extends downward from the front of the bottom surface of the adjustment slider 300 and is integrally formed with the adjustment slider 300. The rear side of the bottom of the interference block 600 contacts the front side of the base 200. Anti-slip grooves 610 are provided on the front side of the base 200 where the interference block 600 contacts. The anti-slip grooves 610 are multiple transverse grooves arranged in parallel along the longitudinal direction. It should be understood that the two positions where the bottom of the interference block 600 contacts the anti-slip grooves 610 correspond to the bottom and top of the anti-slip grooves 610, respectively, where the adjustment screw 400 is fully threaded into the threaded hole 210 and where it is loosened until it disengages from the threaded hole 210 or the stability of the adjustment slider 300 is no longer guaranteed. Furthermore, the anti-slip grooves 610 also increase friction between the interference block 600 and the base 200, thereby improving the base 200's support for the adjustment slider 300 and further ensuring the stability of the adjustment slider 300 and its support for the locking point 100. In addition, the anti-slip pattern 610 can also serve as a marker to help the user understand the adjustable range of the slider 300 .
[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
