Description

Wall anchor components Technical Field

[0001] This utility model belongs to the field of hardware technology, specifically relating to a wall anchor component. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, and easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties, making it one of the new lightweight building materials currently under development. Gypsum board is widely used in various buildings such as residences, office buildings, shops, hotels, and industrial plants for interior partitions, wall cladding (replacing plaster layers), ceilings, sound-absorbing panels, floor baseboards, and various decorative panels. However, due to the material's inherent limitations, gypsum board itself is not very strong and cannot effectively secure bolts. Therefore, anchoring components are typically used to fix gypsum board in place. Common anchoring components consist of threaded sleeves and anchoring elements. After inserting the threaded sleeve assembly into the gypsum board, the anchoring elements need to be adjusted to be perpendicular to the threaded sleeve using bolts to fix the component to the gypsum board. However, the failure rate of this adjustment process is relatively high with current anchoring components, and repeated operations may be necessary to achieve the desired alignment.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] As shown in Figure 1, the wall anchor assembly 100 in one embodiment of this utility model includes a positioning screw sleeve 10, an anchoring member 20, and a fixing bolt 40. The positioning screw sleeve 10 includes a main body 11, two extending arms 12, and a connecting part 13. The main body 11 has a columnar structure with a through hole 111 along its own axial direction. One end of each of the two extending arms 12 is fixed to the main body 11, and their extension direction is parallel to the axial direction of the main body 11. The connecting part 13 is disposed at the other end of the extending arms 12 and forms a rectangular receiving space between the connecting part 13, the extending arms 12, and the main body 11. The anchoring member 20 is at least partially housed in the receiving space and can move along the axial direction of the positioning screw sleeve 10 within the receiving space and rotate relative to the positioning screw sleeve. A through screw hole 21 is provided on the anchoring member 20 in a direction perpendicular to its own axial direction. The fixing bolt 40 is used to push the anchoring member 20 to be inserted into the through hole 111 and the screw hole 21 after it has moved and rotated to be perpendicular to the positioning screw sleeve 10.

[0029] After the anchoring component 100 is drilled into the gypsum board, the fixing bolt 40 is inserted into the through hole 111, and the anchoring component 20 is pushed to move towards the connecting part 13 and rotated 90 degrees, so that the anchoring component 20 is perpendicular to the main body 11. At this time, the through hole 111 and the screw hole 21 are coaxial. After the fixing bolt 40 is pulled back a certain distance, it is screwed into the screw hole 21. Under the action of the thread, the anchoring component 20, after adjusting its posture, moves towards the main body 11 until the anchoring component 20 is fastened to the gypsum board.

[0030] The connecting part 13 has a semi-circular structure as shown in Figure 2. It is used to limit the movement distance of the anchor 20, prevent the anchor 20 from disengaging from the positioning screw sleeve 10, and limit the anchor to rotate only along the opening direction of the semicircle.

[0031] To ensure that the anchor 20 can rotate smoothly to be perpendicular to the positioning screw sleeve 10, a first stop surface 121 is provided on at least one of the two extension arms 12. The first stop surface 121 is located on the side near the connecting part 13, and a matching second stop surface 22 is provided on the outer wall of the anchor 20. As shown in Figure 5, the anchor 20 is located on the side of the main body 11. When it moves towards the connecting part 13, the second stop surface 22 abuts against the first stop surface 121 (as shown in Figure 6). During the continued insertion of the fixing bolt 40, the anchor 20 rotates around the contact position of the two stops surface until the two stops surface are in contact (as shown in Figure 7; for demonstration purposes, there is a gap between the first stop surface 121 and the second stop surface 22 in Figure 7). The through hole 111 is coaxial with the screw hole 21. Since the through hole 111 and the screw hole 21 are coaxial only when the first stop surface 121 and the second stop surface 22 are in contact, whether the two stops are in contact can be sensed by the operator through the fixing bolt 40. Furthermore, the two stops can also prevent the anchor 20 from rotating excessively, thus improving the success rate of the operation and reducing or avoiding the situation of repeated operation.

[0032] For example, in the embodiment shown in Figure 2, the extension arm 12 includes an inner side 122 facing another extension arm 11, and a boss 123 is formed on the inner side 122. The first stop surface 121 is an inclined surface that connects the inner side 122 and the boss 123 and forms a 45-degree angle with the axial direction of the main body 11. The second stop surface 22 is an inclined surface that protrudes from the outer wall of the anchor 20 and forms a 45-degree angle with the axial direction of the anchor 20. When the two inclined surfaces are in contact, the anchor 20 is perpendicular to the positioning screw sleeve 10, and the through hole 111 is coaxial with the screw hole 21.

[0033] Preferably, the aforementioned inclined surface (first stop surface 121) is provided on both extension arms 12, and correspondingly, two aforementioned inclined surfaces (second stop surface 22) are provided on the outer wall of the anchor 20, which further improves the stability of the anchor 20 during rotation, preventing it from rotating or moving in other directions, or even disengaging from the positioning screw sleeve 20.

[0034] A first limiting plate 23 protrudes outward from one side of the anchor 20, and a second limiting plate 24 protrudes outward from the opposite side. The distance between the first limiting plate 23 and the second limiting plate 24 in the axial and vertical directions of the anchor 20 is the same as the width of the extension arm 12. The extension arm 12 is clamped between the first limiting plate 23 and the second limiting plate 24. The two cooperate to fix the anchor 20 on the positioning screw sleeve 10, while restricting the rotation angle of the anchor 20. That is, when the anchor 20 rotates 90 degrees, it is blocked by the ends of the two limiting strips and cannot continue to move.

[0035] Since the anchor 20 can move and rotate simultaneously on the positioning screw sleeve 10, in order to improve the stability of both, the anchor 20 only moves when the fixing bolt 40 pushes. A flexible latch 112 protrudes from the main body 11. The latch 112 is interference-fitted with the anchor 20. Therefore, when the anchor 20 moves to one side of the main body 11, the latch 112 deforms to a certain extent and applies a certain amount of force to the anchor 20, so that the anchor 20 is held at one end of the main body 11 in a coaxial position with the positioning screw sleeve 10, and does not rotate unexpectedly on that side, so as to maintain the posture during the movement and facilitate transportation.

[0036] Preferably, since the latch 112 and the anchor 20 are interference fit, in order to ensure that the anchor 20 can smoothly contact the latch 112 and abut against the main body 11 when it moves, the latch 112 is configured as shown in FIG. 4, which includes a guide surface 1121 facing the extension arm 12. The guide surface 1121 extends from the top of the latch 112 toward the main body 11. Therefore, when the anchor 20 moves toward the main body 11, the arc-shaped guide surface 1121 contacts the anchor 20 first to guide the anchor 20 to continue moving toward the main body 11, thus avoiding the situation where the anchor 20 is stuck by the latch 112 and cannot move.

[0037] Furthermore, a contact surface 1122 is provided between the guide surface 1121 and the main body 11. Since the latch 112 will deform to a certain extent, if the contact surface 1122 is perpendicular to the top surface of the main body 11 under normal conditions, it will not be able to fully contact the anchor 20 when deformation occurs, resulting in a decrease in the force. Therefore, the contact surface 1122 needs to be set to be slightly inclined towards the anchor 20 so that the contact surface 1122 can contact the anchor 20, thereby ensuring the force on the anchor 20.

[0038] In the embodiment shown in Figure 1, the drilling action is performed by the anchor 20, so its end away from the main body 11 extends outside the positioning sleeve 10, and a drill bit 25 is provided at that end. Of course, the drilling operation can also be performed by the positioning sleeve 10, in which case a drill bit is provided at the front end of the positioning sleeve 10, and the anchor 20 is embedded entirely between the main body 11 and the connecting part 13. This embodiment is not limited.

[0039] Preferably, to ensure stability during drilling, a protrusion 131 protrudes from the side of the connecting part 13 away from the main body part 11, and a corresponding slot 251 for accommodating the protrusion 131 is provided on the drill bit 25. By embedding the protrusion 131 into the slot 251, a limiting structure is added at the front end of the entire anchoring assembly 100 to prevent relative rotation or even separation between the positioning screw sleeve 10 and the anchoring member 20.

[0040] Both the drill bit 25 and the positioning screw sleeve 10 are provided with threads 30, and notches 31 are provided on some of the threads 30, especially the tail part of the threads 30, to discharge the debris generated during drilling, and to cut the paper of the gypsum board well, so that the paper surface is flat and smooth.

[0041] As shown in Figure 8, the fixed thread 40 does not use an overall overlay thread. Instead, it has a smooth section 41 without threads at the head. When screwed into the screw hole 21, since there are no threads at the head, it will not collide with the internal threads of the screw hole 21. Even if the angle or insertion position is incorrect, it can slide to the correct insertion position, reducing the need for secondary position adjustments and making it more user-friendly.

[0042] As shown in Figure 8, the fixed thread 40 does not cover the entire thread. A smooth section without threads is provided at the head, and a retractable rod section 41 is provided at the tip. When inserted into the screw hole 21, the smooth retractable rod section 41 will not collide with the thread in the screw hole 21. Even if the angle or insertion position is incorrect, it can slide smoothly to the correct position, reducing the need for secondary position adjustments.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
