Technical Field
[0001] The utility model relates to the technical field of doors and windows, and in particular to a hidden locking center column and a door and window locking mechanism. Background Art
[0002] On September 11, 2023, our company applied for a utility model case for a patent entitled "A Sliding Door and Window Gap Compensation Component", with application number 2023224692882. The patent application discloses a pulling component and a clamping component, wherein the clamping component is arranged on the middle column of the door and window frame, and the pulling component is arranged on the side of the sliding door and window, and the lateral movement is achieved by linkage with the handle of the sliding door and window, and the flat-head screw of the pulling component is clamped with the U-shaped dovetail of the clamping component. Since the middle column is fixed on the door and window frame, and the sliding door and window can slide in the door and window frame, in order to improve the sealing of the sliding door and window, after the flat-head screw is clamped with the U-shaped dovetail of the clamping component, the lateral movement of the flat-head screw can pull the sliding door and window to move sideways on the door and window frame to reduce the gap, thereby increasing the sealing.
[0003] However, in the above case, since the engaging component is protruding from the center column, the pulling component on the sliding door and window is prone to collide with the engaging component due to the lateral clearance during the sliding process of the sliding door and window, thereby causing damage to the sliding door and window and the engaging component.
[0004] Based on the above, the present application proposes a hidden locking center column and door and window locking mechanism to solve the problem of collision damage caused by lateral clearance. Utility Model Content
[0005] The utility model provides a hidden locking center column, which solves the problems mentioned in the above background technology.
[0006] The technical solution of the utility model is achieved in this way:
[0007] A hidden locking center column comprises a door and window center column and a locking block, wherein a locking block is arranged on one side of the door and window center column; a sliding groove is provided on the side of the door and window center column corresponding to the locking block, a sliding block is provided on the side of the locking block close to the door and window center column, and the sliding block slides inside the sliding groove; the sliding groove has convex ribs flush with both sides of the locking block; the locking block is provided with a plurality of screws threadedly mounted with the door and window center column.
[0008] Furthermore, the slide groove is a dovetail groove, the slider is a dovetail block, and the dovetail block and the dovetail groove cooperate with each other.
[0009] Furthermore, a dovetail buckle is provided on one side of the convex rib corresponding to the slide slot, and the dovetail buckle is engaged and connected with the slide slot.
[0010] Furthermore, the screw is installed in a direction obliquely or perpendicular to the locking block.
[0011] Furthermore, a dovetail lock opening is provided on one side of the locking block.
[0012] Furthermore, a support column is provided on the back side of the door and window center column.
[0013] The door and window locking mechanism includes a door and window locking assembly, which is applied to the hidden locking center column; the door and window locking assembly includes a grooved limit strip and a grooved sliding strip that slides laterally inside the grooved sliding strip, and a flat head screw is provided on the grooved sliding strip, and the flat head end of the flat head screw is fitted with a dovetail lock.
[0014] Furthermore, the inside and outside of the groove-type limit bar are respectively slidably provided with a side shift bar and a pull bar, wherein a guide hole is opened in the groove-type limit bar, and an oblique hole is opened in the side shift bar, and a guide block is provided on the pull bar, which passes through the guide hole and extends into the oblique hole; the guide block is respectively slidably connected with the guide hole and the oblique hole.
[0015] Furthermore, the side of the side shift bar away from the pull bar is fixedly connected to the groove-shaped sliding bar.
[0016] Furthermore, the groove-shaped limiting strip is provided with a plurality of guide shafts, wherein the groove-shaped sliding strip is sleeved on the guide shafts and slides along the outside thereof.
[0017] Beneficial effects of the technical solution provided by this application:
[0018] 1. The hidden locking center column is provided with convex ribs at the position of the door and window center column, and the convex ribs are used to surround the two sides of the lock block to align it with the door and window center column, so as to prevent the lock block from protruding outward and causing collision with the door and window locking mechanism; in addition, a dovetail slider and a dovetail groove are provided on the lock block to achieve hidden interlocking, and the position is limited by screws to fix it at the position required for the corresponding door and window locking mechanism.
[0019] 2. The hidden locking center column will be deformed due to the drag of the pulling force during the engagement process between the door and window locking mechanism and the lock block. In this case, a support column is provided on the door and window center column to improve the stability of the door and window center column and avoid bending. In order to ensure that the lock block does not protrude, it is necessary to provide an entire structure wrapped around the outside of the lock block on the center column. Since the center column itself is relatively long, the structure surrounding the lock block needs to be ensured to be at the same height as the center column in order to completely improve the aesthetics. The added structure surrounding the lock block will increase the cost. The lock block can be hidden by providing ribs and dovetail grooves, and there is no need to provide an additional structure wrapped around the outside of the lock block, thereby avoiding cost increases.
[0020] 3. The door and window locking mechanism can prevent the sliding door and window from colliding with the door and window locking components due to the protrusion of the lock block during the sliding process when the lock block is hidden in the center column. The up and down movement of the lock block pull bar can act on the side shift bar in the grooved limit bar through the guide block. The side shift bar moves sideways through the cooperation of the oblique hole and the guide block to pull the flat head screw on the grooved sliding bar. The flat head screw pulls the dovetail lock of the lock block to the door and window center column. Then, the door and window center column can improve the overall balance and stability through the support column to avoid deformation of the door and window center column due to dragging.

[0030] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] In the prior art, the upper and lower guide wheel assemblies of sliding doors and windows usually have the function of lateral movement, which is mainly generated by the output of the gear transmission assembly during the rotation of the handle, and then acts on the transmission assembly linked to the upper and lower guide wheel assemblies respectively. The guide wheels of the upper and lower guide wheel assemblies are limited in the slide grooves at the top and bottom of the door and window frame, so the lateral movement will not drive the door and window frame to move, but directly act on the sliding door and window to make the sliding door and window slide laterally, and then move closer to the middle of the door and window frame to improve the sealing and locking effect. However, only by the lateral displacement of the upper and lower guide wheels, it cannot be guaranteed that the side of the sliding door and window can also achieve the locking effect. There will still be a gap between the side of the sliding door and window and the door and window frame after the lateral movement. In order to improve the sealing and locking effect of the side of the sliding door and window and the door and window frame, in this embodiment, in addition to retaining the lateral sliding function of the upper and lower guide wheel assemblies of the prior art, a structure that can cooperate to lock the side of the sliding door and window is also provided.
[0032] Reference Figure 1-3 , a hidden locking center column, including a door and window center column 100 and a locking block 120; because the door and window center column 100 is arranged in the door and window frame, in order to provide a locking function after the side of the sliding door and window is lateral displaced, a locking block 120 is arranged on one side of the door and window center column 100. The setting of the locking block 120 is mainly to provide a limit, and a lateral displacement mechanism is arranged on the side of the sliding door and window to complete a snap-on connection with the locking block 120. Then, the lateral displacement mechanism can reduce the gap between the door and window center column 100 through lateral movement, thereby improving the sealing effect.
[0033] In order to prevent the lock block 120 from protruding from the door and window center column 100, convex ribs 102 flush with the door and window center column 100 are provided on both sides of the corresponding lock block 120 of the door and window center column 100; the convex ribs 102 can surround the outside of the lock block 120, so that the lock block 120 is embedded in the door and window center column 100, ensuring that the lock block 120 is flush with the door and window center column 100, avoiding the protrusion that affects the appearance and easily causing the sliding of the sliding door and window to collide with the lock block 120.
[0034] The specific installation method of the lock block 120 on the door and window center column 100 is as follows: a slide groove 101 is provided on the side of the door and window center column 100 corresponding to the lock block 120, and a slider 121 is provided on the side of the lock block 120 close to the door and window center column 100, and the slider 121 slides inside the slide groove 101; the sliding installation can quickly match the height of the lateral displacement mechanism set on the side of the sliding door and window, and adjust the position of the lateral displacement mechanism. In addition, the lock block 120 is provided with a plurality of screws 122 threadedly installed with the door and window center column 100. After the lock block 120 is adjusted to the height corresponding to the lateral displacement mechanism, the lock block 120 is locked and fastened by the screws 122.
[0035] In some embodiments, the slide groove 101 is a dovetail groove, and the slider 121 is a dovetail block, and the dovetail block cooperates with the dovetail groove. The cooperation between the dovetail block and the dovetail groove can prevent the locking block 120 from falling off or loosening during installation or use, so that the locking block 120 and the door and window center column 100 are locked with each other. The characteristic of this connection method is that the connection is very tight and stable.
[0036] In some embodiments, a dovetail buckle 103 is provided on one side of the rib 102 corresponding to the slide slot 101, and the dovetail buckle 103 is engaged with the slide slot 101. Figure 2 The top exploded view of the hidden locking center column shown in the figure shows that the dovetail buckle 103 is specifically arranged to be composed of two hooks, and there is a certain distance between the two hooks, which is adapted to the width of the dovetail chute, and the purpose is mainly to facilitate the dovetail buckle 103 composed of two hooks to be buckled in the dovetail chute. The dovetail buckle 103 is matched with the spacing distance between the two hooks, so that there is space for bending and deformation between the two hooks. When the dovetail buckle 103 is inserted from the front of the dovetail chute, the hook heads of the two hooks set apart are bent relative to each other at the moment of entering the dovetail chute. After entering the inside of the dovetail chute, the two hooks of the dovetail buckle 103 are engaged in the dovetail chute. The convex rib 102 is limited in the dovetail chute of the door and window center column 100 by the dovetail buckle 103, so that the locking block 120 is protected. The setting of the convex rib 102 can also ensure that the locking block 120 is aligned with the door and window center column 100, thereby realizing a hidden setting.
[0037] In some embodiments, the screw 122 is installed in an oblique direction or perpendicular to the direction of the locking block 120. When the screw 122 is installed perpendicular to the direction of the locking block 120, the locking block 120 will not be skewed or offset by forming a mutually perpendicular angle with the locking block 120, because the locking block 120 itself is limited by the dovetail slot, and then the vertical limit is used, so that the locking block 120 will not be skewed or offset, thereby increasing its stability. When the oblique installation is adopted, the force distribution of the screw 122 is more uniform, and the tensile or shear force in the force direction can be more effectively resisted, thereby improving the strength of the connection; when the locking block 120 is pulled by the lateral displacement mechanism set on the side of the sliding door and window, since the direction of the force is not directly perpendicular to the thread axis, a certain pressure will be generated on the thread, thereby increasing the friction between the threads and preventing the screw from loosening by itself; the oblique installation can disperse the stress of the locking block 120 to a larger area, thereby reducing the single-point stress concentration, which helps to reduce fatigue damage and deformation of parts or structures and extend the service life.
[0038] In some embodiments, a dovetail lock opening 123 is provided on one side of the lock block 120. The dovetail lock opening 123 is mainly provided to provide a limiting condition for the lateral displacement mechanism provided on the side of the sliding door and window. The dovetail lock opening 123 is convenient for engaging with the lateral displacement mechanism, and then the lateral displacement mechanism drives the sliding door and window to move inside the door and window frame through lateral displacement under the limiting condition and approaches the inner side of the door and window frame, thereby increasing the sealing and locking effect.
[0039] In some embodiments, a support column 110 is provided on the back of the door and window center column 100. When the lock block 120 on the door and window center column 100 is subjected to the lateral pulling force of the lateral displacement mechanism, the door and window center column 100 may be deformed and bent due to frequent pulling, thereby affecting the stability of the door and window center column 100. In order to increase the supporting effect of the door and window center column 100 and prevent deformation, the support column 110 plays an auxiliary supporting effect on the door and window center column 100.
[0040] For a clearer understanding of how the lateral displacement mechanism mentioned in the technical solution of the hidden locking center column is specifically engaged with the adapter lock block 120 and lateral displacement is achieved, please refer to Figure 4-5 The door and window locking mechanism includes a door and window locking assembly 200, which is applied to the hidden locking center column; the door and window locking assembly 200 includes a groove-type limit strip 220 and a groove-type sliding strip 230 that slides laterally inside the groove-type sliding strip 230, and a flat-head screw 231 is provided on the groove-type sliding strip 230, and the flat-head end of the flat-head screw 231 is snap-fitted with the dovetail lock 123.
[0041] The door and window locking assembly 200 is the lateral displacement mechanism mentioned in the technical solution of the above-mentioned hidden locking center column. First, a grooved limit strip 220 and a grooved sliding strip 230 that slides laterally therein are provided. Since the grooved sliding strip 230 can complete lateral sliding in the grooved limit strip 220, the conditions for lateral displacement are basically met. Further, a flat-head screw 231 is provided on the grooved sliding strip 230 to engage with the dovetail lock 123, and the door and window locking assembly 200 is provided on the side of the sliding door and window. When the sliding door and window slide in the door and window frame, the flat-head screw 231 and the dovetail lock 123 complete the engaging action, and the sliding door and window are pulled by the locking block 120 on the door and window center column 100. When the grooved sliding strip 230 slides laterally on the grooved limit strip 220, the grooved limit strip 220 drives the sliding door and window to approach the door and window center column 100, thereby achieving the purpose of reducing the gap.
[0042] In some embodiments, a side shift bar 240 and a pull bar 210 are slidably disposed inside and outside the groove-shaped limit bar 220, respectively, wherein a guide hole 221 is provided in the groove-shaped limit bar 220, and an oblique hole 241 is provided in the side shift bar 240, and a guide block 211 is provided on the pull bar 210, and the guide block 211 passes through the guide hole 221 and extends into the oblique hole 241; the guide block 211 is slidably connected to the guide hole 221 and the oblique hole 241, respectively; and the side of the side shift bar 240 away from the pull bar 210 is fixedly connected to the groove-shaped sliding bar 230.
[0043] By limiting the sliding of the pull rod 210 to the side of the sliding door and window (connecting one end of the pull rod 210 to the gear rack transmission assembly of the handle mechanism, the specific situation is based on the actual situation), the pull rod 210 can only slide up and down on the side of the sliding door and window. When the pull rod 210 slides up and down on the side of the sliding door and window, the guide block 211 on the pull rod 210 slides up and down along the guide hole 221 of the groove-type limit strip 220. Since the guide block 211 is respectively slidably connected to the guide hole 221 and the oblique hole 241, the sliding of the guide block 211 in the oblique hole 241 is converted from oblique and vertical restrictions to lateral movement.
[0044] Furthermore, because the side of the side shift bar 240 away from the pull bar 210 is fixedly connected to the grooved sliding bar 230, if the flat end of the flat head screw 231 on the grooved sliding bar 230 is engaged with the dovetail lock 123, the position of the grooved sliding bar 230 is pulled by the lock block 120 on the door and window center column 100, then the grooved sliding bar 230 and the side shift bar 240 are fixed parts; the guide block 211 passes through the guide hole 221 so that the grooved limit bar 2 20 is pulled and restricted by the pull strip 210, because the pull strip 210 is restricted on the side of the sliding door and window, then the groove-shaped limit strip 220 and the pull strip 210 act as movable parts, when the guide block 211 on the movable part moves in the oblique hole 241 of the fixed part, the up and down vertical movement is converted from oblique to left and right lateral movement, and the lateral movement of the pull strip 210 as a movable part will pull the sliding door and window to fit close to the door and window center column 100, thereby achieving the purpose of sealing.
[0045] In some embodiments, the groove-shaped limit bar 220 is provided with a plurality of guide shafts 222, wherein the groove-shaped sliding bar 230 is sleeved on the guide shafts 222 and slides along the outside thereof. The setting of the guide shafts 222 mainly serves the purpose of guiding during the lateral displacement process. When the groove-shaped sliding bar 230 slides laterally between the groove-shaped limit bar 220, the groove-shaped limit bar 220 supports and balances the groove-shaped sliding bar 230 through the guide shafts 222, and can also provide a sliding guide during the sliding process to avoid sliding stagnation and jamming.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
