Description

Technical Field

[0001] This utility model relates to the field of door and window hardware accessories, and in particular to lock box components and lock box installation structures. Background Technology

[0002] Existing top locks typically consist of a lock box and a lock body. The lock box is located on the upper slide rail, and the lock body is located on the sliding door. The lock tongue of the lock body can slide up and down relative to the sliding door. When the lock tongue extends upward and enters the lock box, the sliding door is locked; when the lock tongue retracts downward and separates from the lock box, the sliding door is unlocked.

[0003] However, the existing lock box installation method for top locks has significant drawbacks. The lock box can only be inserted into the upper track from its end along its extension direction. If the upper track is fixed to the top of the doorway first, and then the lock box is fixed into the upper track, the installation of the lock box is extremely difficult due to the limited installation space. It may even require an additional access port to be opened in the upper track to install the lock box, which not only increases installation costs and complexity but may also affect the overall structural strength of the upper track. If the lock box is fixed into the upper track first, and then the upper track is fixed to the top of the doorway, it will be difficult to adjust the position of the lock box relative to the upper track. Due to installation or manufacturing errors, there may be inaccurate fit between the lock box and the latch, causing the top lock to fail to properly lock and unlock the sliding door, affecting product performance and user experience.

[0034] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0035] Please see Figures 1 to 4 This application provides a lock box assembly for being disposed on an upper track 4. The upper track 4 has a track groove 41, the track groove 41 has a groove side wall 413, a groove top wall 411 and a groove bottom wall 412, and the groove bottom wall 412 is provided with a groove opening 414.

[0036] The lock box assembly includes a fixing block 1, a lock box body 2, and fasteners 3; the fixing block 1 is inserted into the top wall 411 of the track groove 41; the lock box body 2 can rotate relative to the fixing block 1 between a first position and a second position; when the lock box body 2 is in the first position, please refer to [the relevant documentation]. Figure 1 The lock box body 2 can be inserted upward into the track groove 41 from the slot opening 414; when the lock box body 2 is in the second position, please refer to the details. Figure 3 The two sides of the lock box body 2 are respectively used to abut against the side wall 413 or the groove opening 414 to achieve pre-fixation; the fastener 3 is connected between the fixing block 1 and the lock box body 2, and the fastener 3 can drive the lock box body 2 in the second position to abut against the bottom wall 412 of the groove downward.

[0037] The lock box assembly disclosed in this application firstly uses a fixing block 1 inserted into the top wall 411 of the track groove 41, serving as a preliminary connection with the upper track 4 and providing basic support for the installation of the lock box body 2. The lock box body 2 can rotate relative to the fixing block 1 between a first position and a second position. Secondly, when the lock box body 2 is in the first position, it can be inserted upwards into the track groove 41 from the groove opening 414 without needing to be inserted laterally from the end of the upper track 4. This effectively solves the problem of installation difficulties caused by limited installation space, eliminates the need for additional inspection ports, reduces installation costs and complexity, and improves installation efficiency. When the lock box body 2 is in the second position, both sides of the lock box body 2 are used to abut against the side wall 413 or the opening 414 of the groove to achieve pre-fixation. At this time, the lock box body 2 is in an adjustable state, which makes it easy for construction personnel to make fine adjustments to the position of the lock box body 2 according to the actual situation, so as to ensure that the lock box body 2 and the lock tongue can be precisely matched. Furthermore, the fastener 3 is connected between the fixing block 1 and the lock box body 2. The fastener 3 can drive the lock box body 2 in the second position to abut against the bottom wall 412 of the groove, so that the lock box body 2 and the upper rail 4 form a firm connection, enhance the fixing stability of the lock box assembly, and ensure the long-term reliable operation of the top lock.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the fastener 3 is screwed onto the lock box body 2. When the lock box body 2 is in the first position, rotating the fastener 3 can drive the lock box body 2 to rotate synchronously. When the lock box body 2 rotates to the second position under the drive of the fastener 3, due to the thread drive between the fastener 3 and the lock box body 2, continuing to rotate the fastener 3 can drive the lock box body 2 to press downward against the bottom wall 412 of the groove. Thus, on the first aspect, when the lock box body 2 is in the first position, rotating the fastener 3 can drive the lock box body 2 to rotate synchronously. This synchronicity ensures the stability and controllability of the lock box body 2 during the rotation process. Construction personnel can precisely control the rotation angle of the fastener 3 according to actual needs, thereby accurately rotating the lock box body 2 to the second position to achieve precise contact with the groove side wall 413 or the groove opening 414, completing the pre-fixing. Secondly, after the lock box body 2 rotates to the second position, due to the threaded drive between the fastener 3 and the lock box body 2, rotating the fastener 3 can drive the lock box body 2 to press against the bottom wall 412 of the groove downwards. The threaded drive has self-locking and adjustability. Construction personnel can finely control the tightness between the lock box body 2 and the bottom wall 412 of the groove by finely adjusting the rotation amount of the fastener 3 according to the actual situation on site. This fine adjustment can ensure that a firm and suitable connection is formed between the lock box body 2 and the upper track 4, further improving the accuracy and stability of the installation.

[0039] like Figure 1 , Figure 3and Figure 4 As shown, in one embodiment, the fastener 3 is vertically arranged, passing through the fixing block 1 and screwed to the lock box body 2. When the lock box body 2 rotates to the second position under the drive of the fastener 3, one end of the fastener 3 passes through the fixing block 1 and abuts against the top wall 411 of the groove. Due to the thread drive between the fastener 3 and the lock box body 2, continued rotation of the fastener 3 can drive the lock box body 2 downward to abut against the bottom wall 412 of the groove. Thus, the lock box assembly of this embodiment has good adaptability and can adapt to upper rails 4 of different sizes and shapes. Since the position and abutment degree of the lock box body 2 can be controlled by adjusting the rotation amount of the fastener 3, the lock box assembly can be adjusted according to the actual installation situation to ensure perfect fit with the upper rail 4. Whether in new construction or old house renovation projects, the lock box assembly can be easily installed and used, improving the product's versatility and market competitiveness. Furthermore, when maintenance or replacement of the lock box assembly is required, the connection between the lock box body 2 and the upper track 4 can be loosened simply by rotating the fastener 3. This simple disassembly method makes maintenance and replacement more convenient, reducing repair time and costs. At the same time, because the connection between the fastener 3 and the lock box body 2 is clear and straightforward, maintenance personnel can quickly locate and repair problems, improving repair efficiency and quality.

[0040] like Figure 4 and Figure 5 As shown, in one embodiment, the lock box body 2 is provided with a connecting groove 23, a connecting piece 5 is provided in the connecting groove 23, and a connecting screw hole 51 is provided on the connecting piece 5. The fixing block 1 is provided with a limiting hole 14, and the fastener 3 is screwed into the connecting screw hole 51, with one end of the fastener 3 passing through the limiting hole 14. This avoids directly providing screw holes on the lock box body 2. With this structure, the design of the lock box body 2 can focus more on the structural optimization of its core functional parts, without having to consider the impact of screw hole placement on the overall structure. At the same time, the connecting piece 5 can be individually designed and replaced according to different fastener 3 specifications and installation requirements, without needing to redesign and manufacture the entire lock box body 2. This improves the flexibility and scalability of product design, enabling rapid adaptation to market demands for lock box components of different specifications and performance.

[0041] It should be noted that in some other embodiments, screw holes can also be directly made on the lock box body 2. The design can be based on actual needs and is not limited here.

[0042] In some embodiments, one end of the fastener 3 may be screwed or rotatably connected to the limiting hole 14, and the design can be made according to actual needs, without being limited to a single one.

[0043] In one embodiment, the lock box body 2 includes an upper body 21 and a lower body 22 connected to each other, with the lower body 22 connected to the lower side of the upper body 21. When the lock box body 2 is in the second position, the upper body 21 is located within the track groove 41, and the two sides of the lower body 22 are respectively used to abut against the two sides of the groove opening 414 to achieve pre-fixation. Thus, the abutment between the lower body 22 and the two sides of the groove opening 414 achieves pre-fixation, facilitating the initial adjustment of the lock box body 2's position. In the pre-fixed state, the lock box body 2 is not completely fixed, and construction personnel can fine-tune the lock box body 2 according to the actual situation to make its position more accurate. This adjustability makes the installation process more flexible, adaptable to different installation environments and installation errors, reduces installation difficulty, and reduces the need for reinstallation due to inaccurate positioning. Specifically, in this embodiment, the cooperation relationship between the lower body 22 and the locking tongue is as follows: the locking tongue of the lock body can slide up and down relative to the sliding door body. When the locking tongue extends upward and enters the lower body 22, the sliding door body can be locked; when the locking tongue retracts downward and separates from the lower body 22, the sliding door body can be unlocked.

[0044] like Figure 5 and Figure 6 As shown, in one embodiment, the lower body 22 has a blocking wall 223 for cooperating with the locking tongue to achieve the above-mentioned locking or unlocking.

[0045] like Figure 3 and Figure 5 As shown, in one embodiment, the connecting groove 23 is disposed on the upper body 21; it should be noted that in some other embodiments, the connecting groove 23 may also be disposed on the lower body 22, depending on the actual needs.

[0046] like Figure 5 and Figure 6 As shown, in one embodiment, the upper body 21 and the lower body 22 are integrally formed. This design eliminates the connection gaps and weak points that may exist in the split structure, making the lock box body 2 a highly rigid whole. When subjected to external forces, such as vibrations, impacts, and latching forces generated during the opening and closing of the sliding door, the integrated structure can more effectively disperse and transfer stress, avoiding structural deformation or damage caused by local stress concentration. This greatly improves the structural strength and stability of the lock box body 2 and extends the service life of the product.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, in one embodiment, the lower body 22 has two opposing limiting sidewalls 221. When the lock box body 2 is in the second position, the two limiting sidewalls 221 abut against the two sides of the slot opening 414 respectively. The first end of the limiting sidewall 221 is provided with a relief slope 222. During the process of the lock box body 2 rotating from the first position to the second position along the first direction, the relief slope 222 can move relative to the slot opening 414 to allow the lock box body 2 to rotate to the second position. When the lock box body 2 rotates from the first position along the second direction, the second end of the limiting sidewall 221 can abut against the sidewall of the slot opening 414 to restrict the rotation of the lock box body 2. The first direction and the second direction are opposite. Thus, firstly, the setting of the avoidance slope 222 provides a clear guiding effect for the lock box body 2 to rotate from the first position to the second position along the first direction. During the rotation, the avoidance slope 222 can move smoothly relative to the slot opening 414, guiding the lock box body 2 to rotate along the correct path. This guiding function ensures that the lock box body 2 can accurately reach the second position, so that the lock box body 2 can be accurately placed in the appropriate position in the track slot 41, laying the foundation for the accurate cooperation with the lock tongue in the future, and effectively avoiding the problem of poor cooperation between the lock box and the lock tongue caused by deviation in the rotation direction or inaccurate position. Secondly, when the lock box body 2 rotates from the first position along a second direction opposite to the first direction, the second end of the limiting sidewall 221 can abut against the sidewall of the slot opening 414, thereby restricting the rotation of the lock box body 2. This design cleverly prevents the lock box body 2 from reversing, avoiding installation errors caused by operator misoperation or incorrect judgment of the installation direction. Installation errors not only increase installation time and cost, but may also affect the normal use of the lock and even cause product damage. By abutting and restricting the second end of the limiting sidewall 221, such problems are effectively avoided, improving the accuracy and reliability of installation.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, a limiting groove 211 is provided on the lower side of the upper body 21. When the lock box body 2 is in the second position and is pressed downward against the bottom wall 412 of the groove, the limiting groove 211 is used to engage with the limiting protrusion 415 on the bottom wall 412 of the groove. With this configuration, firstly, the limiting groove 211 provided on the lower side of the upper body 21 cooperates with the limiting protrusion 415 on the bottom wall 412 of the groove, playing a precise positioning role during the installation of the lock box body 2. When the lock box body 2 is in the second position and is pressed downward against the bottom wall 412 of the groove, the limiting groove 211 and the limiting protrusion 415 can automatically engage, so that the position of the lock box body 2 in the track groove 41 is accurately determined. This precise positioning avoids positional deviation of the lock box body 2 during installation, ensures that the lock box and other components such as the lock tongue can be accurately matched, improves the quality and reliability of the top lock installation, and reduces problems such as door locking and unlocking difficulties caused by inaccurate installation position. Secondly, the snap-fit ​​design of the limiting groove 211 and the limiting protrusion 415 simplifies the installation process for installers. Installers do not need to spend a lot of time and effort to precisely adjust the position of the lock box body 2. They only need to put the lock box body 2 into the track groove 41 and press it downwards. When they hear or feel the limiting groove 211 and the limiting protrusion 415 snap into place, they can be sure that the lock box body 2 is installed in the correct position. This fast and accurate positioning method greatly shortens the installation time and improves the installation efficiency, and is especially suitable for large-scale production or rapid installation scenarios.

[0049] like Figure 3 and Figure 4 As shown, in one embodiment, the limiting groove 211 is an arc-shaped groove. This design allows the installer to make small-range rotations and adjustments without completely removing the lock box body 2 during installation if the initial position or angle is inaccurate, in order to try and find the correct locking position. This flexibility reduces the need for repeated removal and placement of the lock box body 2, lowers the installation difficulty, and improves installation efficiency, making it particularly suitable for scenarios with limited installation space or inconvenient operation.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment, the side of the limiting protrusion 415 facing the limiting groove 211 is also arc-shaped.

[0051] It should be noted that in some other embodiments, the limiting groove 211 may also be, but is not limited to, a square groove or a trapezoidal groove, etc., and can be selected according to actual needs. There is no unique limitation here.

[0052] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, in one embodiment, a guide block 11 is provided on the side wall of the fixing block 1. The guide block 11 is used to guide the fixing block 1 into the fixing groove 416 of the top wall 411. Thus, the guide block 11 on the side wall of the fixing block 1 provides clear guidance for the fixing block 1 to be inserted into the fixing groove 416 of the top wall 411. During installation, the installer does not need to spend a lot of time and effort to precisely adjust the position and direction of the fixing block 1. The guide block 11 will guide the fixing block 1 to be accurately inserted into the fixing groove 416 along the correct path, ensuring precise positioning between the fixing block 1 and the fixing groove 416. This not only improves the accuracy of installation but also avoids problems such as insecure fixing and poor component fit caused by installation position deviations, ensuring the overall quality and reliability of the top lock installation.

[0053] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, in one embodiment, the fixing block 1 includes two opposing fixing sidewalls 12, with a hollow portion 13 formed between the inner sides of the two fixing sidewalls 12. A guide block 11 is disposed on the outer side of the fixing sidewalls 12. With this configuration, since the hollow portion 13 is formed on the inner sides of the two fixing sidewalls 12, a certain elastic deformation can occur between the two fixing sidewalls 12 during the process of the fixing block 1 being inserted into the fixing groove 416 of the top wall 411. This elastic deformation allows the fixing block 1 to be inserted more smoothly into the fixing groove 416 when encountering situations such as a slightly small inlet size of the fixing groove 416 or minor obstructions in the installation path, through its own structural elastic adjustment. Installers do not need to use excessive force to forcibly push the fixing block 1 in, reducing resistance and operational difficulty during installation and greatly improving installation convenience, especially suitable for scenarios with narrow installation spaces and inconvenient operation.

[0054] In addition, such as Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment also provides a lock box installation structure, including the lock box assembly as described in any of the above embodiments, and further including an upper track 4. The upper track 4 has a track groove 41. The track groove 41 has a groove side wall 413, a groove top wall 411 and a groove bottom wall 412. The groove top wall 411 and the groove bottom wall 412 are arranged vertically opposite to each other. The groove side wall 413 is connected between the groove top wall 411 and the groove bottom wall 412. The groove bottom wall 412 is provided with a groove opening 414. The fixing block 1 is inserted into the groove top wall 411.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a fixing groove 416 is provided on the top wall 411 of the groove, and the fixing block 1 is inserted into the fixing groove 416.

[0056] In summary, the lock box assembly and lock box mounting structure disclosed in this utility model can bring at least the following beneficial technical effects:

[0057] (1) The lock box body 2 can be inserted into the track groove 41 from the slot opening 414 upwards, without the need to insert it from the end of the upper track 4. This effectively solves the problem of installation difficulties caused by small installation space, eliminates the need for additional maintenance ports, reduces installation costs and complexity, and improves installation efficiency.

[0058] (2) The lock box body 2 can be finely adjusted in the pre-fixed state, which overcomes the problem of difficulty in adjusting the lock box position in the prior art. It can flexibly adjust the lock box position according to the actual situation, effectively avoid the situation of inaccurate matching between the lock box and the lock tongue due to installation error or production error, and improve the installation accuracy and reliability of the lock.

[0059] (3) The lock box body 2 is driven downward by the fastener 3 to abut against the bottom wall 412 of the groove, so that a firm connection is formed between the lock box body 2 and the upper track 4. This can effectively resist the interference of external factors, such as vibration and impact, and ensure that the lock box assembly always maintains a stable state during use, thus ensuring the long-term reliable operation of the lock and extending the service life of the product.

[0060] (4) Due to the threaded drive between the fastener 3 and the lock box body 2, rotating the fastener 3 can drive the lock box body 2 to press against the bottom wall 412 of the groove downwards. The threaded drive has self-locking and adjustable properties. Construction personnel can finely control the tightness between the lock box body 2 and the bottom wall 412 of the groove by finely adjusting the rotation amount of the fastener 3 according to the actual situation on site.
