Gypsum board anchoring assembly

Abstract

The invention discloses a gypsum board anchoring assembly. The gypsum board anchoring assembly comprises a positioning screw sleeve, an anchoring piece and a fixing bolt. The first protruding rib and the second protruding rib which protrude out are arranged on the positioning threaded sleeve and the anchoring piece respectively, the second protruding rib can cut the first protruding rib and generate a notch in the moving process of the anchoring piece, and then the second protruding rib moves in the formed notch and does not face other directions, so that the anchoring piece does not rotate in the moving process, and the anchoring piece does not rotate in the moving process. And only when the positioning screw sleeve moves to the tail end of the positioning screw sleeve and the second convex rib is separated from the first convex rib, the positioning screw sleeve can rotate, so that the situation that the posture of the positioning screw sleeve needs to be frequently adjusted through a fixing bolt due to advanced rotation is avoided, the operation time is shortened, and the working efficiency is improved.

Description

Technical Field

[0001] The invention belongs to the technical field of hardware materials, and in particular relates to a gypsum board anchoring assembly. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. Gypsum board has been widely used in various buildings such as residential, office buildings, shops, hotels and industrial plants, such as interior partitions, wall covering panels (instead of wall plastering), ceilings, sound-absorbing panels, ground base panels and various decorative panels. However, due to the material itself, the strength of gypsum board itself is not high and bolts cannot be fixed well. Therefore, gypsum board usually uses anchoring components to make fixed positions. Common anchoring components consist of a rotating screw sleeve group and a bolt. After the screw sleeve group is inserted into the gypsum board, the movable screw sleeve needs to be adjusted and the screw sleeve group is anchored to the gypsum board by bolts. The movable screw sleeve rotates on the other side of the gypsum board. The traditional screw sleeve group often fails to rotate into place and needs to be adjusted frequently with bolts, which is time-consuming and laborious.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] like Figure 1-8 As shown, a gypsum board anchor assembly in an embodiment of the present invention includes a positioning screw sleeve 10, an anchor member 20 and a fixing bolt 30.

[0029] The positioning screw sleeve 10 includes a first columnar main body 12 and two extension arms 13 extending from the first main body 12. An accommodating space is formed between the two extension arms 13. The extension direction of the two extension arms 13 is parallel to the axial direction of the first main body 12. The inner side of the extension arm 13 protrudes with a first rib 131 perpendicular to the extension direction of the extension arm 13. The first main body 12 is also provided with a through hole 11 that penetrates along its own axial direction, and a stop ring 14 is provided at the distal end of the extension arm 13.

[0030] The anchor 20 includes a columnar second main body 22, which is provided with a screw hole 21 extending perpendicularly to its own axial direction and a first arc-shaped guide surface 222 facing the stop ring 14, and a second convex rib 224 extending parallel to its own axial direction is protruded on its side wall. The anchor 20 is at least partially accommodated in the accommodation space and can move along the axial direction of the positioning screw sleeve 10, and under the cooperation of the stop ring 14 and the first guide surface 222, the anchor 20 can rotate relative to the positioning screw sleeve 10.

[0031] In actual operation, firstly, the positioning screw sleeve 10 and the anchor member 20 are coaxial (such as Figure 1 As shown in FIG. 1 , the positioning screw sleeve 10 is drilled in the gypsum board. When the positioning screw sleeve 10 is almost completely inserted into the gypsum board, the anchor member 20 is also completely located behind the gypsum board. Figure 3 , the anchor 20 is rotated 90°, at which time the anchor 20 is axially perpendicular to the positioning screw sleeve 10, and the through hole 11 is aligned with the screw hole 21. The anchor 20 is transverse to the positioning screw sleeve 10 and is located behind the gypsum board, performing an anchoring positioning function, so that the positioning screw sleeve 10 cannot move in the axial direction of the drilled hole.

[0032] The fixing bolt 30 is used to be inserted into the through hole 11 after the positioning screw sleeve 10 and the anchor 20 are inserted into the gypsum board, contact and push the anchor 20 to move to the stop ring 14 at the far end of the positioning screw sleeve 10 and rotate, and then inserted into the screw hole 21 and tightened. The anchor 20 moves toward the first main body 12 (gypsum board) under the meshing of the thread until it contacts and presses on the gypsum board, thereby fixing the entire gypsum board anchor assembly on the gypsum board.

[0033] In actual use, after the positioning screw sleeve 10 is almost completely inserted into the gypsum board, when the anchor 20 is pushed to move in the direction away from the first main body 12 (the distal end of the positioning screw sleeve 10) by the fixing bolt 30, the ideal situation is that the anchor 20 moves axially upward in the accommodating space without deflection, and rotates again when the first guide surface 222 abuts the stop ring 14. However, during actual operation, the anchor 20 may rotate in advance during the movement process, and the fixing bolt 30 cannot contact and push the anchor 20 well, resulting in difficulty in the movement of the anchor 20, and the need to frequently adjust the fixing bolt 30. Therefore, the first convex rib 131 and the second convex rib 224 are respectively provided on the positioning screw sleeve 10 and the anchor 20. The positioning screw sleeve 10 and the anchor 20 are drilled into or enter the gypsum board in a coaxial posture, and the first convex rib 131 is perpendicular to the second convex rib 224. When the fixing bolt 30 pushes the anchor 20 to move, the end of the second rib 224 contacts and cuts the first rib 131 to create a notch. In the subsequent movement process, the remaining part of the second rib 224 will move in the notch cut on the first rib 131, so that it will not move in other directions until it moves to the farthest end and the second rib 224 is separated from the first rib 131. Therefore, under the cooperation of the first rib 131 and the second rib 224, the anchor 20 will not rotate in advance, ensuring its posture during movement, without the need to frequently adjust the anchor 20 through the fixing bolt 30, reducing the operation time and improving work efficiency.

[0034] In actual use, the anchor 20 is first adjusted to be coaxial with the positioning screw sleeve 10 and inserted into the gypsum board from one end. Then the fixing bolt 30 is inserted into the through hole 11, and the anchor 20 is pushed to move to the far end of the positioning screw sleeve 10 on the other side of the gypsum board and rotated to make the screw hole 21 coaxial with the through hole 11. Finally, the fixing bolt 30 is inserted, and the fixing bolt 30 passes through the through hole 11 (for the convenience of operation, the through hole 11 is not threaded) in turn and then screwed into the screw hole 21. Under the action of the thread, the anchor 20 approaches and abuts the gypsum board. Continuing to rotate the fixing bolt 30 can fix the positioning screw sleeve 10 and the anchor 20 on the gypsum board. Then, the fixing bolt 30 is pulled out, and at this time, the positioning screw sleeve 10 and the anchor 20 are in a vertical state, and the first convex rib 131 and the second convex rib 224 are in a parallel state. Even if the anchor 20 loses its traction force when the fixing bolt 30 is pulled out, causing the anchor 20 to move away from the first main body 12, the first convex rib 131 will block the second convex rib 224, thereby preventing the anchor 20 from moving too far away from the first main body 12 and keeping it in a vertical state. At this time, move the object to be fixed to the vicinity of the positioning screw sleeve 10, pass the fixing bolt 30 through the object to be fixed, and then re-insert it into the screw hole 21 through the through hole 11 and tighten it.

[0035] Preferably, a plurality of first convex ribs 131 are provided on the extension arm 13, so that when the anchor 20 moves toward the first main body 12, the second cross bar 224 can move between two adjacent first convex ribs 131. At this time, even if the fixing bolt 30 is pulled out, the second convex rib 224 is restricted by the adjacent first convex ribs 131, so that the anchor 20 is limited between the adjacent first convex ribs 131, and will not move or rotate significantly. When reinserting the fixing bolt 30 or other threaded components, there is no need to readjust the anchor 20. Therefore, the gypsum board anchor assembly in this embodiment can replace the fixing bolt 30 with a threaded hook or other threaded component when needed midway without readjustment, and has higher flexibility.

[0036] like Figure 6 As shown, a support plate 23 and a limit strip 24 are protruded from the second main body 22, and the two are arranged on both sides of the main axis of the second main body 22, and are arranged in a staggered manner in a direction perpendicular to the main axis of the second main body 22, that is, they are arranged on both sides of the screw hole 21. And the distance between the support plate 23 and the limit strip 24 in the axial direction of the screw hole, and the minimum distance in the axial direction of the second main body 22 are the same as the width of the extension arm 13. In this embodiment, the extension arm 13 is arranged between the support plate 23 and the limit strip 24, and the two cooperate to clamp the extension arm 13, so that the anchor 20 is fixed on the positioning screw sleeve 10. And because the distance between the support plate 23 and the limit strip 24 in two directions is the same as the width of the extension arm 13, the anchor 20 can be rotated 90° on the positioning screw sleeve 10 and will not be disengaged, thereby improving the overall ease of use.

[0037] like Figure 3 As shown, one side of the support plate 23 abuts against the gypsum board, which is configured as Figure 6 The long strip plate structure in the gypsum board can increase the contact area with the gypsum board, prevent or reduce the deformation of the gypsum board, and further improve the stability and load-bearing capacity of the gypsum board.

[0038] Furthermore, a stop ring 14 is provided at the distal end (the end away from the first main body 12) of the positioning screw sleeve 10, and its two ends are connected to the extension arm 13, which is used to improve the overall strength of the positioning screw sleeve 10, provide support for the drilling assembly, and prevent the extension arm 13 from deforming during the drilling process. Secondly, the anchor 20 is limited when it rotates to prevent it from rotating excessively.

[0039] In actual use, after drilling into the gypsum board, the posture of the anchor 20 is adjusted at the other end of the gypsum board. Usually, the other end of the gypsum board cannot be directly touched, so its adjustment action basically needs to be performed through the fixing bolt 30, and the action of the fixing bolt 30 is limited to the through hole 11. Therefore, in order to improve the success rate and avoid multiple adjustments, a guide surface structure is provided on the second main body 22. After the anchor 20 is abutted and pushed to move by the fixing bolt 30, the first guide surface 222 approaches and contacts the stop ring 14. When the fixing bolt 30 is continued to be operated to push the anchor 20 to move, the anchor 20 rotates under the cooperation of the stop ring 14 and the first guide surface 222 until it is perpendicular to the positioning screw sleeve.

[0040] Preferably, in order to further improve the success rate of posture adjustment, an arcuate second guide surface 223 is also provided on the second main body 22, and the second guide surface 223 is provided at a position on the second main body 22 away from the first guide surface 222, and the two guide surfaces are parallel to each other. At this time, after the fixing bolt 30 is inserted, the fixing bolt 30 abuts against the arcuate second guide surface 223 when moving toward the anchor 20, and then moves toward the stop ring 14 under the cooperation of the two sets of limit strips and the extension arm 13. When the first guide surface 222 abuts against the stop ring 14, under the dual cooperation of the first guide surface 222 and the stop ring 14, and the second guide surface 223 and the fixing bolt 30, the anchor 20 can be rotated faster and smoother to be perpendicular to the positioning screw sleeve 10, and the success rate is higher, and there is no need to repeatedly adjust the fixing bolt 30.

[0041] After the anchor 20 is rotated to be perpendicular to the positioning screw sleeve 10, the screw hole 21 faces the through hole 11. If the fixing bolt 30 is fully covered by the thread, the fixing bolt 30 may not be inserted into the screw hole 21 during rotation due to the insertion angle (not inserted vertically), even if the fixing bolt 30 contacts the screw hole 21, it may still be impossible to select the fixing bolt 30 into the screw hole 21 during rotation, resulting in the need to adjust the insertion position and angle of the fixing bolt 30 in order to successfully insert it into the screw hole 21. Therefore, preferably, the fixing bolt 30 is not entirely covered with threads, and a first smooth section 31 without threads is provided at the head position. The first smooth section 31 first contacts the end of the screw hole 21. Since it has no threads, it will not collide with the threads of the screw hole 21. Even if the angle or insertion position is incorrect, it can slide to the correct insertion position without the need for secondary position adjustment, and is more user-friendly.

[0042] Furthermore, the fixing bolt 30 is a three-section design, including a first smooth section 31 at the head, a second smooth section 32 at the tail, and a threaded section 33 between the first smooth section 31 and the second smooth section 32. The fixing bolt 30 is configured such that when the threaded section 33 abuts against the screw hole 21 in a correct posture under the action of the first smooth section 31, the other end of the threaded section 33 is immersed in the through hole 11, that is, the entire threaded section 33 is inserted into the through hole 11, and only the second threaded section 32 is exposed in the through hole 11. In this way, the operator is reminded that the fixing bolt 30 abuts against the screw hole 21 in a correct posture only when the threaded section 33 is not observed, and only at this time can the fixing bolt 30 be correctly engaged with the anchor 20 by rotating it.

[0043] Preferably, in one embodiment, the second smooth section 32 and the threaded section 33 have the same diameter, and the first smooth section 31 has a smaller diameter than the second smooth section 32 and the threaded section 33. The head of the fixing bolt 30 can slide into the screw hole 21 more easily by shrinking the rod.

[0044] Preferably, a fixing block 141 protrudes from the stop ring 14, a support block 27 is provided at the head of the anchor 20, and a slot 271 is provided on the support block 27. When the gypsum board anchor assembly is in the initial state, the support block 141 is supported on the stop ring 14, and the fixing block 141 is inserted into the slot 271. The gypsum board anchor assembly is punched in the initial state, and the anchor 20 is driven to rotate by the positioning screw sleeve 10. The fixing block 141 and the slot 271 cooperate to play a positioning role, which is used to limit the head position of the anchor 20 and improve the stability during rotation to prevent the anchor 20 from detaching from the positioning screw sleeve 10 during rotation.

[0045] The traditional anchor assembly adopts a single-pointed spiral form, which has a large friction force with the gypsum board when drilling. Since the two screw sleeves are movably connected, the large friction force between the two screw sleeves and the gypsum board may cause the two screw sleeves to separate. Figure 6As shown, the anchor 20 also includes a drilling assembly protruding from the support block 27, specifically including a main drill bit 25 coaxial with the second main body 20, and a scraper 26 arranged on the periphery of the main drill bit 25, and the height of the main drill bit 25 located in the middle position is greater than the height of the peripheral scraper 26. Each scraper 26 is connected to the main drill bit 25 through a connecting portion 28, and the two connecting portions 28 are parallel to each other and staggered. In this embodiment, the main drill bit 25 at the middle position first contacts the gypsum board and determines the drilling position. After drilling a certain distance, the scraper 26 contacts the gypsum board and cooperates with the main drill bit 25 to drill. Under the cooperation of the main drill bit 25 and the scraper 26, a relatively regular cylindrical hole is drilled on the gypsum board, which greatly reduces the friction between the rest of the gypsum board anchor assembly and the gypsum board, thereby preventing the positioning screw sleeve 10 and the anchor 20 from being separated. At the same time, the two connecting portions 28 can also discharge the debris generated by drilling, thereby helping to improve the drilling efficiency.

[0046] In one embodiment, one of the scrapers 26 and the connection portion 28 connecting the scraper 26 and the main drill bit 25 is flush with the support plate 23 (eg, Figure 7 As shown), the contact area between the anchor 20 and the gypsum board is further increased, thereby preventing the anchor 20 from sinking into the gypsum board.

[0047] In one embodiment, since a drilling mechanism (such as a screwdriver, a pistol drill, etc.) acts on the positioning screw sleeve 10 during drilling, and the positioning screw sleeve 10 drives the anchor 20 to rotate, a fixing groove 121 is provided on the first main body 12, and a fixing foot 221 protrudes from the second main body 22 accordingly. When the anchor 20 is coaxial with the positioning screw sleeve 10, the fixing foot 221 is correspondingly embedded in the fixing groove 121. The fixing groove 121 and the fixing foot 221, as well as the fixing block 141 and the clamping groove 271 respectively fix the positioning screw sleeve 10 and the anchor 20 from both ends to prevent the two screw sleeves from being out of sync during drilling, or even idling.

[0048] For example, Figure 4 and 6 In the embodiment shown, two parallel fixed legs 221 are protruded from the second main body 22, and two fixed grooves 121 are correspondingly provided on the first main body 12, so that the force on each fixed leg 221 can be reduced to avoid the situation where a single fixed leg 221 is subjected to excessive force and breaks. Of course, the fixed legs 221 and the fixed grooves 121 can be provided in other numbers, and their positions can be interchanged, that is, a column is provided on the positioning screw sleeve 10, and a groove is provided on the anchor 20, which is not limited in this embodiment.

[0049] Preferably, in order to improve the stability between the positioning screw sleeve 10 and the gypsum board, a spiral thread 122 is provided on the first main body 12, and a plurality of cutting grooves 1221 are provided on the thread 122 to improve the cutting effect with the surface of the gypsum board and prevent the surface of the gypsum board from peeling.

[0050] The positioning screw sleeve 10 includes a countersunk head 123 at the end of the first main body 12, and a backstop rib 1231 is also provided on the countersunk head 123. The backstop rib 1231 is located on the side of the countersunk head 123 facing the extension arm 13, and is used to increase the friction between the positioning screw sleeve 10 and the gypsum board to further avoid shaking or loosening.

[0051] In addition, an indicator arrow 1232 is provided on the side of the countersunk head 123 facing away from the extension arm 13, and the indicator arrow 1232 points to the direction of the drilling assembly in a vertical posture. When two or more gypsum board anchoring assemblies need to be arranged at a relatively close distance, in order to avoid collision between two or more anchoring members 20, the indicator arrow 1232 can be used to distinguish the direction of the drilling assembly, and then adjust the overall direction.

[0052] In one embodiment, the positioning screw sleeve 10 and the anchor 20 are separately manufactured and then assembled, wherein the anchor 20 also needs to bear the drilling operation, so it is made of metal material to improve the strength. The positioning screw sleeve 20 is made of plastic, so that the extension arm 13 can produce a certain deformation, and the anchor 20 can be inserted into the extension arm 13 during assembly, so that the anchor 20 can move between different first ribs 131.

[0053] It should be understood that, in addition to being applied to gypsum boards, the gypsum board anchor assembly in this embodiment can also be applied to other scenarios where fixing bolts 30 are required.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0055] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
