[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0031] Example 1:
[0032] Reference Figure 1-8The concealed door and window locking structure includes a lock box 100, a support plate 200, a lock hook 300, and a lock base. The lock box 100 has first guide grooves 110 on both its front and rear sides. Two support plates 200 are symmetrically distributed on the front and rear sides of the lock hook 300, with respect to the center of the front and rear sides. The support plates 200 can slide relative to the lock box 100 in a first direction, where the first direction is upward.
[0033] The tray 200 has a second guide groove 210 that runs through the front and back. The length direction of the second guide groove 210 is the left-right direction, that is, perpendicular to the first direction. The end of the first guide groove 110 extending along the first direction is inclined towards the direction in which the lock hook 300 needs to extend out of the lock box 100, that is, the upper end of the first guide groove 110 is inclined to the left, and the inclination angle is between 0 degrees and 90 degrees.
[0034] The locking hook 300 is located inside the locking box 100. The locking hook 300 is provided with rollers 310. The middle part of the rollers 310 passes through the locking hook 300. After passing through the side wall of the locking hook 300, the two ends of the rollers 310 pass through the second guide groove 210 and the first guide groove 110 on the corresponding side.
[0035] The lock base includes a base 600 and a lock shaft 620. The base 600 has a lock groove 610 on the side facing the lock box 100. The lock shaft 620 is placed horizontally in the lock groove 610 in the front-back direction. There is a certain space between the lock shaft 620 and the bottom wall of the lock groove 610 for the lock hook 300 to be inserted.
[0036] When the drive plate 200 slides upward relative to the lock box 100, the roller 310 can slide to the left relative to the drive plate 200 along the second guide groove 210. At the same time, the roller 310 can slide to the upper left relative to the lock box 100 along the first guide groove 110, thereby driving the lock hook 300 to slide relative to the lock box 100 along the path of the first guide groove 110. This allows the hook of the lock hook 300 to extend out of the lock box 100 to the upper left and be inserted obliquely into the gap between the lock shaft 620 and the bottom wall of the lock groove 610. Since the movement of the lock hook 300 has an upward displacement, the lock hook 300 can hook the lock shaft 620, thereby achieving the effect of locking the door and window.
[0037] When unlocked, the lock hook 300 is located inside the lock box 100, preventing it from protruding from the door or window structure. This prevents the lock hook 300 from scratching people or damaging property, reducing the safety risks associated with the lock hook 300 and improving security. Furthermore, the door or window structure with the lock box 100 installed can become flat, simple, and aesthetically pleasing.
[0038] The outer surface of the roller 310 is cylindrical. Two rollers 310 are arranged side-by-side along the vertical direction of the locking hook 300. The support plate 200 also has two second guide grooves 210 arranged side-by-side along the vertical direction. Two first guide grooves 110 are also arranged side-by-side along the vertical direction on both sides of the locking box 100. This design makes the sliding movement of the locking hook 300 smoother and more reliable.
[0039] Furthermore, both ends of the first guide groove 110 are provided with extension sections 113, the length direction of the extension sections 113 being vertical. In the initial stage of sliding the pallet 200 relative to the lock box 100, the roller 310 remains at the rightmost end of the second guide groove 210, while the roller 310 slides in the extension section 113 on the right side of the first guide groove 110. At this time, the lock hook 300 has not extended out of the lock box 100.
[0040] When the roller 310 begins to enter the first guide groove 110, the roller 310 begins to slide from the rightmost end of the second guide groove 210 to the left, and the locking hook 300 begins to extend out of the lock box 100 and is inserted at an angle into the lock seat.
[0041] When the roller 310 enters the extension 113 at the left end of the first guide groove 110 and slides, the roller 310 reaches the leftmost end of the second guide groove 210, and the locking hook 300 moves upward and is inserted deeper into the lock seat, improving the locking strength and stability. It is understood that, to ensure the tightness of the locking hook 300, the locking hook 300 has a hook groove, and the inner side of the hook groove is inclined with an inclined surface 301 that matches the inclined direction or trajectory of the second guide groove 210. In other embodiments, the extension 113 may only be provided at the left end of the first guide groove 110.
[0042] Furthermore, the lock box 100 includes an upper block 101, a lower block 102, and two cover plates 104. The upper and lower ends of the two cover plates 104 are respectively mounted on the upper block 101 and the lower block 102, and the two cover plates 104 are positioned at the front and rear sides of the upper block 101 and the lower block 102, respectively. A first guide groove 110 is provided on the cover plate 104. Side plates extend from the right sides of the two cover plates 104 in a direction of mutual approach, allowing the support plate 200 to abut against the cover plate 104 and the side plates, thereby enabling the two support plates 200 to slide on the side of the two cover plates 104 that are close to each other. The front cover plate 104, the front support plate 200, the lock hook 300, the rear support plate 200, and the rear cover plate 104 are stacked sequentially.
[0043] Furthermore, the lock box 100 also includes a clamping plate 105, the upper and lower ends of which are respectively mounted on the upper side block 101 and the lower side block 102 by bolts. The clamping plate 105 has a limiting hole 106, which extends through the lock in the left-right direction. The limiting hole 106 has four side walls, which respectively abut against the opposite sides of the upper side block 101 and the lower side block 102, and the opposite sides of the two cover plates 104. It can be understood that after the two cover plates 104 are respectively installed on the sides of the upper side block 101 and the lower side block 102 to form a frame structure, the clamping plate 105 is then fitted onto the frame structure, and the frame structure fits into the limiting hole 106, thereby stabilizing the frame structure and improving the overall stability of the lock box 100.
[0044] Furthermore, this embodiment also includes a pull rod 400 and a panel 500. Two pull rods 400 are provided, each connected to the upper and lower ends of the support plate 200 respectively. That is, the upper pull rod 400 is connected to the upper ends of both support plates 200, and the lower pull rod 400 is connected to the lower ends of both support plates 200. The panel 500 has a U-shaped cross-section and is fitted onto the left side of the lock box 100, with the pull rod 400 positioned between the panel 500 and the lock box 100. The panel 500 has a through hole 510 through which the lock hook 300 can pass. Screws are threaded through both the upper and lower ends of the panel 500 and are connected to the lock box 100, thereby connecting the panel 500 and the lock box 100. A second groove 440 with the length direction in the up-down direction is provided on the pull rod 400. The screw slides in the second groove 440, which can provide sliding guidance and limit for the pull rod 400.
[0045] Specifically, the screws include mounting screws 520 and fixing screws 530. The two mounting screws 520, positioned vertically, are threadedly connected to the upper block 101 and lower block 102 in the lock box 100, respectively. The fixing screw 530, after passing sequentially through the second sliding groove 440 of the corresponding pull rod 400 and the corresponding upper block 101 or lower block 102, is threadedly connected to the clamping plate 105. This improves the connection stability between the panel 500 and the lock box 100, as well as the sliding stability of the pull rod 400.
[0046] Furthermore, the pull rod 400 is equipped with a stepped hook point 410. First sliding grooves 103 are provided on both the upper block 101 and the lower block 102, with the length of the first sliding groove 103 running vertically. The stepped hook point 410 of the upper pull rod 400 slides within the first sliding groove 103 of the upper block 101 and partially protrudes from the right side of the upper block 101. This allows the stepped hook point 410 to be connected to a transmission mechanism, facilitating the sliding of the pull rod 400 via a handle or similar component, thereby causing the support plate 200 to slide upwards and achieve locking. The stepped hook point 410 of the lower pull rod 400 slides within the first sliding groove 103 of the lower block 102 and partially protrudes from the right side of the lower block 102. This allows the stepped hook point 410 to be connected to a transmission mechanism, facilitating the sliding of the pull rod 400 via a handle or similar component, thereby causing the support plate 200 to slide downwards and achieve unlocking.
[0047] Specifically, slots 420 are provided on both the front and rear sides of the pull rod 400, and a protrusion structure 430 is formed between the end of the pull rod 400 and one side wall of the slot 420. A groove 220 is provided on the left side of the support plate 200, and a locking block structure 230 is formed between the end of the support plate 200 and one side wall of the groove 220. When the pull rod 400 is inserted and assembled with the two support plates 200 from left to right, the two protrusion structures 430 are respectively embedded in the grooves 220 of the two support plates 200. At the same time, the locking block structure 230 of the support plate 200 is embedded in the corresponding slot 420, so that the pull rod 400 is connected to the two support plates 200. When the pull rod 400 is pulled in the up and down direction, the support plate 200 can be stably slid.
[0048] It should be noted that the left and right sides of the tray 200 abut against the side walls of the panel 500 and the cover plate 104 respectively, thereby ensuring the stable sliding of the tray 200.
[0049] Example 2:
[0050] Reference Figure 9 The difference between this embodiment and Embodiment 1 lies in the shape and orientation of the second guide groove 210. In this embodiment, the end of the second guide groove 210 extending along the first direction is inclined in the opposite direction to where the locking hook 300 needs to extend out of the lock box 100, that is, the upper end of the second guide groove 210 is inclined to the right, with an inclination angle ranging from 0 degrees to 90 degrees. When the roller 310 slides in the second guide groove 210, the displacement in the vertical direction can offset the pulling distance of the pull rod 400, making the vertical sliding displacement of the locking hook 300 less than that of the pull rod 400. Therefore, the inclination angle of the second guide groove 210 can be set according to actual needs.
[0051] When the drive plate 200 slides upward relative to the lock box 100, the roller 310 can slide downward to the left relative to the drive plate 200 along the second guide groove 210. At the same time, the roller 310 can slide upward to the left relative to the lock box 100 along the first guide groove 110, thereby driving the lock hook 300 to slide relative to the lock box 100 along the path of the first guide groove 110. This allows the hook of the lock hook 300 to extend upward to the left from the lock box 100 and be inserted obliquely into the gap between the lock shaft 620 and the bottom wall of the lock groove 610. Alternatively, the hook of the lock hook 300 can first extend to the left from the lock box 100 and then be inserted into the gap between the lock shaft 620 and the bottom wall of the lock groove 610 under the guidance of the extension section 113, thus achieving the effect of locking the door and window.
[0052] Example 3:
[0053] Reference Figure 10 The difference between this embodiment and Embodiment 1 lies in the shape and orientation of the first guide groove 110 and the second guide groove 210. In this embodiment, the first guide groove 110 includes a first segment 111 and a second segment 112, with one end of the first segment 111 connected to one end of the second segment 112. The length direction of the first segment 111 is left-right, that is, perpendicular to the first direction. The length direction of the second segment 112 is up-down, that is, parallel to the first direction. In other words, the first guide groove 110 is L-shaped.
[0054] The second guide groove 210 is inclined at one end along the first direction in the opposite direction to the direction in which the lock hook 300 needs to extend out of the lock box 100, that is, the upper end of the second guide groove 210 is inclined to the right, and the inclination angle is between 0 degrees and 90 degrees.
[0055] When the drive plate 200 slides upward relative to the lock box 100, the roller 310 can slide downward to the left relative to the drive plate 200 along the second guide groove 210. At the same time, the roller 310 can slide to the left relative to the lock box 100 along the first section 111, thereby driving the lock hook 300 to slide relative to the lock box 100 along the path of the first guide groove 110. This allows the hook of the lock hook 300 to first extend to the left from the lock box 100, and then, under the guidance of the second section 112, insert into the gap between the lock shaft 620 and the bottom wall of the lock groove 610, thus achieving the effect of locking the door and window.
[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
