Description

Technical Field

[0001] This utility model belongs to the field of finished building materials technology, and specifically discloses a sliding and fixing lock for boards. Background Technology

[0002] In the installation of building materials, connection and fixing are crucial steps, with accurate positioning being a significant challenge, especially in the installation of gypsum board products. Inaccurate positioning can lead to irregular joints, stress concentration, and subsequent warping and cracking. Traditional board connection methods involve butt-fitting each board individually. This method results in the positional accuracy of each subsequent board depending on the positional accuracy of the previous one. The cumulative error after installing multiple boards is significant, and the installation process is time-consuming, labor-intensive, and requires a high level of worker skill, leading to low efficiency. While adhesive bonding can achieve a tighter connection, the adhesive's effectiveness can be affected by environmental conditions such as temperature and humidity, resulting in poor bonding in certain environments. Furthermore, the curing time required for the adhesive also reduces construction efficiency. In addition, adhesives may release harmful gases, posing risks to the environment and human health.

[0003] In scenarios where the panels require movable and adjustable functions, such as movable display racks and adjustable furniture, traditional fixing methods are insufficient. Existing connection methods cannot allow for easy repositioning and re-fixing of the panels after they are fixed, limiting the flexibility and versatility of the product. As the demands for panel usage continue to increase across industries, there is an urgent need for a connection device that can achieve quick and convenient connection, ensure flexible sliding and adjustment of the panels when needed, and provide stable fixation once in place. The panel sliding and fixing lock was developed to solve these problems. Utility Model Content

[0004] To address the technical problems listed in the background section, this utility model provides a sliding and fixing lock for sheet metal. The specific technical solution is as follows: A sliding and fixing lock for sheet metal includes a locking button and a locking seat. The locking button includes a locking part and a connecting part. The connecting part is a rod with threads on its outer periphery for fixing to a load-bearing structure. The locking part has a flange with an axial connecting neck and a nut adjacent to the flange and mating with the threads on the rod. The flange can be detachably installed at one end of the rod through the axial connecting neck. The locking seat is a rigid sleeve structure, including a sleeve bottom and a sleeve surface. The sleeve bottom has a positioning hole for fitting and positioning with the sheet metal. The sleeve surface has a locking groove parallel to the installation direction of the sheet metal. The locking groove has an entry eye and a locking eye at both ends. The size of the entry eye is sufficient to allow the flange surface to pass through. Both the locking eye and the locking groove can allow the axial connecting neck to pass through and can block the flange surface from passing through.

[0005] Preferably, one locking eye connects two locking slots, the two locking slots are parallel to the two adjacent sides of the board, and the locking eye is circular with a diameter greater than the width of the locking slot.

[0006] Preferably, the thread on the outer circumference of the rod has two sections. The thread on the section of the rod near the flange is a standard external thread with a thread length equal to the thickness of the nut that it is mating with. The thread from the end of the standard external thread to the other end of the rod is a self-tapping thread.

[0007] Preferably, the axial connecting neck is installed at one end of the rod by screwing, and the flange surface is provided with a slotted or cross-shaped groove.

[0008] Preferably, the other end of the rod is also provided with a detachable locking part.

[0009] Preferably, a strip-shaped pressure spring is installed inside the lock seat from the entry buttonhole to the locking buttonhole, and the distance between the pressure spring and the sleeve surface gradually decreases from the entry buttonhole to the locking buttonhole.

[0010] Compared with the prior art, this utility model has the following advantages: This utility model provides a sliding and fixing lock for sheet metal. Because the bottom of the lock seat has positioning holes, the lock seat can be precisely fixed to the sheet metal by aligning the positioning holes with the locking grooves on the sleeve surface. Following the principle that the installation positions of sheets of the same model are basically consistent, the specific installation points on the load-bearing structure can be determined. Locking buttons are then fixed at these installation points, and the locking buttons are inserted into the lock seat and the sheet metal is fixed to the load-bearing structure through the locking grooves. Since the locking grooves have a certain length, the final position of the sheet metal during sliding and fixing can be slightly adjusted to meet the needs of seam alignment, ensuring good positional accuracy of the installed sheet metal. This allows for quick and convenient connection while ensuring that the sheet metal can be flexibly slid and adjusted when needed, and can be stably fixed after adjustment. This reduces the use of glue and allows for convenient repositioning and refixation in the future, facilitating the reuse of sheet metal after exhibitions and other events, and is environmentally friendly.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] like Figure 1-4 As shown, the plate sliding fixing lock proposed in this embodiment includes a locking button and a locking seat. The locking button includes a locking part and a connecting part. The connecting part is a rod with threads on its outer periphery for fixing to the load-bearing structure. The locking part is provided with a flange 1 with an axial connecting neck and a nut 5 adjacent to the flange and engaged with the threads on the rod. The flange 1 can be detachably installed on one end of the rod through the axial connecting neck 2. The locking seat is a rigid sleeve structure, including a sleeve bottom 11 and a sleeve surface 10. The sleeve bottom 11 is provided with a positioning hole 13 for fitting and positioning with the plate. The sleeve surface 10 has a locking groove 8 parallel to the installation direction of the plate. The locking groove 8 has an entry eye 9 and a locking eye 7 at both ends. The size of the entry eye 9 is sufficient to allow the flange surface to pass through, and the locking groove 8 is just enough to allow the axial connecting neck 2 to pass through. The diameter of the locking eye 7 is larger than the width of the locking groove 8 and can block the flange surface from passing through.

[0014] In another embodiment, a locking eyelet 7 connects two locking slots 8 (see...) Figure 3 The two locking grooves 8 are parallel to the two adjacent sides of the plate, and in this embodiment the plate can have two sliding installation directions.

[0015] The rod has two sections of threads on its outer circumference. The thread near the flange is a standard external thread 3, with a thread length equal to the thickness of the mating nut 5. The thread from the end of the standard external thread 3 to the other end of the rod is a self-tapping thread 4. The connection has two implementations: in the first implementation, the rod is a single unit, and the axial connecting neck 2 is screwed to one end of the rod; in the second implementation, the rod has a self-tapping screw with a threaded sleeve screwed to one end. The external thread of the threaded sleeve is a standard external thread 3, and the end is welded to the axial connecting neck 2. The threaded section where the self-tapping screw and the threaded sleeve are screwed together is a reverse standard thread 6.

[0016] The flange surface is uniformly provided with a cross groove for tightening.

[0017] Other embodiments also include a detachable locking part at the other end of the rod (see...). Figure 4 ).

[0018] In all the above embodiments, a strip-shaped compression spring 12 is installed inside the lock seat from the entry buttonhole 9 to the locking buttonhole 7. The distance between the compression spring 12 and the sleeve surface gradually decreases from the entry buttonhole 9 to the locking buttonhole 7.

[0019] During on-site installation, first, based on the positional relationship between the positioning hole 13 and the locking groove 8, install the lock seat on the back of the plate at the designated position; then, install the locking button at the specific installation point on the load-bearing structure. After fixing the locking button at the installation point, the locking button can be inserted into the lock seat and the plate can be fixed on the load-bearing structure through the locking groove. Since the locking groove 8 has a certain length, and the diameter of the locking eye 7 is greater than the width of the locking groove 8, it also provides a certain amount of room for the locking button to move. This allows the plate to be slightly adjusted in the final position of sliding and fixing, so that the plate is in the set installation position.

[0020] The embodiment with a detachable locking part at the other end of the rod is suitable for application scenarios where double walls are installed on opposite sides of a load-bearing structure. The two plates are combined with the locking button and locking seat at both ends of the rod to form a whole, which is stronger and more aesthetically pleasing.

[0021] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
