Description

Technical Field

[0001] This invention relates to the field of building decoration tools and fixtures, and specifically refers to an adjustable long-arm keel clamping and fixing device for users to use in wall panel bonding and fixing. Background Technology

[0002] In existing wall panel decoration processes, decorative panels are typically glued to the two sides of the wall frame. Since the adhesive requires curing time, temporary fixing is necessary to prevent misalignment and detachment of the panels, ensuring a firm and accurate bond. Current temporary fixing devices mostly use wooden frames erected on-site for support, which is time-consuming and labor-intensive. Furthermore, when the top of the wooden frame presses against the decorative panel, the point of contact is uneven, easily causing hollow areas and warping of the adhesive layer, making it difficult to guarantee the flatness of the panels. To solve the problems caused by this construction process, a new type of clamping and fixing device needs to be developed to temporarily fix the glued wall panels. This device should be convenient and quick to use, have adjustable spacing to suit decorative walls of different widths, and ensure the flatness of the decorative panels. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the above-mentioned situation by providing a convenient and quick adjustable long-arm keel clamping and fixing device with adjustable spacing to suit decorative walls of different widths and ensuring the flatness of the decorative panels.

[0004] To achieve the above objectives, the technical solution of this invention is as follows: an adjustable long-arm keel clamping and fixing device, comprising a left square support arm, a right square support arm, a left clamping square arm, a right clamping square arm, a left clamping adjusting screw assembly, a right clamping adjusting screw assembly, a first adjusting screw assembly, and a second adjusting screw assembly, wherein...

[0005] The first and second adjustable screw assemblies are identical in structure. They are connected in parallel and spaced apart between the left and right square support arms to adjust the distance between them.

[0006] The left clamping adjusting screw assembly and the right clamping adjusting screw assembly are structurally identical. The left clamping adjusting screw assembly is threaded to the top of the left square tube support arm, and the free end of the left clamping square tube assembly is connected to the left clamping square tube arm to adjust the inward parallel clamping stroke of the left clamping square tube arm. The right clamping adjusting screw assembly is threaded to the top of the right square tube support arm, and the free end of the right clamping adjusting screw assembly is connected to the right clamping square tube arm to adjust the inward parallel clamping stroke of the right clamping square tube arm.

[0007] After assembly, the left square tube support arm is rotatably connected to the left clamping square tube arm via the left clamping adjusting screw assembly shaft, and the right square tube support arm is rotatably connected to the right clamping square tube arm via the right clamping adjusting screw assembly shaft.

[0008] The first adjustable pitch screw assembly includes: a screw, a pressure seat, and a base. The pressure seat is fixed on the left side support arm, and the base is fixed on the right side support arm. The screw body is connected to the rotating bearing inside the pressure seat, and the threaded end of the screw is threadedly connected to the threaded hole of the base.

[0009] The left clamping adjusting screw assembly includes: a rocker arm, a live flange, a flange fixing plate, and a fixing screw. The live flange is welded to the flange fixing plate, and the fixing screw fixes the flange fixing plate to the left clamping square tube arm. The threaded rod of the rocker arm passes through the threaded sleeve at the top of the left square tube support arm. The free end of the rocker arm is a smooth rod, which is inserted into the live flange to rotate within the live flange.

[0010] The left and right square support arms have the same structure. A support arm clip is connected to the front end of the left square support arm by a self-tapping screw, and the threaded sleeve is fixed on the support arm clip.

[0011] The movable flange includes a flange sleeve, a movable insert, and a positioning screw. The movable insert is inserted into the flange sleeve, and the positioning screw passes through the threaded hole of the flange sleeve and abuts against the movable insert to control the rotation of the movable insert. During assembly, the flange sleeve is welded to the flange fixing plate, and the free end of the rocker arm is sleeved in the movable insert.

[0012] The screw includes a handle, a rotating ring, and a lead screw connected in sequence.

[0013] The base includes a base threaded sleeve and a base fixing plate.

[0014] The pressure seat includes: pressure seat screw sleeve one, pressure seat screw sleeve two, fastening washer, circular washer, pressure seat screw, pressure seat nut, rotating bearing, bearing seat, and fixing plate. The rotating bearing is built into the bearing seat. The pressure seat screw passes through the bearing seat and fixing plate in sequence and is locked by the pressure seat nut. After assembly, pressure seat screw sleeve one, pressure seat screw sleeve two, fastening washer, and circular washer are sequentially sleeved and fixed to the front threaded end of the lead screw. The optical shaft of the lead screw is assembled on the rotating bearing.

[0015] The left square tube support arm, right square tube support arm, left clamping square tube arm, and right clamping square tube arm are all square tubes.

[0016] By adopting the above structure, this new type of structure solves the problems of traditional wooden frame support being time-consuming and labor-intensive, and easily leading to uneven stress on the wall panels; and has the following features: 1) The left and right square tube support arms are set in parallel and connected by two identical adjustable screw assemblies. The distance between the two support arms can be precisely adjusted in parallel by rotating the screws to adapt to decorative walls of different widths; 2) The left and right clamping square tube arms are respectively connected to the top of the support arms by left and right clamping adjustment screw assemblies. The design of the clamping adjustment screw assembly allows the clamping square tube arms to be precisely moved inward in parallel clamping when the rocker arm is rotated; 3) All support arms and clamping arms adopt a square tube structure with good rigidity and not easily deformed. Therefore, this new composite structure ensures that a large-area, evenly distributed parallel clamping force is applied to both sides of the decorative panel during clamping, effectively preventing the hollowing phenomenon caused by excessive local pressure in the adhesive layer and the warping and deformation of the panel, significantly improving the flatness and bonding firmness of the decorative panel; at the same time, the screw adjustment method is convenient and efficient to operate, greatly saving manpower and time costs, and can be used for temporary fixing of the panel surface of decorative walls of different widths.

[0030] The adjustable long-arm keel clamping device of this embodiment includes a left square support arm 10, a right square support arm 20, a left clamping square arm 30, a right clamping square arm 40, a left clamping adjusting screw assembly 50, a right clamping adjusting screw assembly 60, a first adjusting screw assembly 70, and a second adjusting screw assembly 80, wherein...

[0031] The first adjusting screw assembly 70 and the second adjusting screw assembly 80 are components with the same structure. The first adjusting screw assembly 70 and the second adjusting screw assembly 80 are connected in parallel and spaced between the left square support arm 10 and the right square support arm 20 to adjust the distance between the left square support arm 10 and the right square support arm 20 in parallel.

[0032] The left clamping adjusting screw assembly 50 and the right clamping adjusting screw assembly 60 are structurally identical. The left clamping adjusting screw assembly 50 is threaded to the top of the left square tube support arm 10, and the free end of the left clamping square tube arm 30 is connected to adjust the inward parallel clamping stroke of the left clamping square tube arm 30. The right clamping adjusting screw assembly 60 is threaded to the top of the right square tube support arm 20, and the free end of the right clamping adjusting screw assembly 60 is connected to the right clamping square tube arm 40 to adjust the inward parallel clamping stroke of the right clamping square tube arm 40.

[0033] After assembly, the left square support arm 10 is rotatably connected to the left clamping square arm 30 via the rotating shaft of the left clamping adjusting screw assembly 50, and the right square support arm 20 is rotatably connected to the right clamping square arm 40 via the rotating shaft of the right clamping adjusting screw assembly 60.

[0034] The first adjustable pitch screw assembly 70 includes: screw 71, pressure seat 72, and base 73. Pressure seat 72 is fixed on the left side support arm 10, and base 73 is fixed on the right side support arm 20. The shaft of screw 71 is connected to the rotating bearing 727 inside pressure seat 72, and the threaded end of screw 71 is threadedly connected to the threaded hole of base 73.

[0035] The left clamping adjusting screw assembly 50 includes: a rocker arm 51, a live flange 52, a flange fixing plate 53, and a fixing screw 54. The live flange 52 is welded to the flange fixing plate 53, and the fixing screw 54 fixes the flange fixing plate 53 to the left clamping square tube arm 30. The threaded rod of the rocker arm 51 passes through the threaded sleeve 11 at the top of the left square tube support arm 10. The free end of the rocker arm 51 is a smooth rod 511, which is inserted into the live flange 52 to rotate within the live flange 52.

[0036] The left square support arm 10 and the right square support arm 20 have the same structure. The front end of the left square support arm 10 is connected to the support arm clip 13 by a self-tapping screw 12, and the threaded sleeve 11 is fixed on the support arm clip 13.

[0037] The movable flange 52 includes a flange sleeve 521, a movable insert 522, and a positioning screw 523. The movable insert 522 is inserted into the flange sleeve 521. The positioning screw 523 passes through the threaded hole of the flange sleeve 521 and abuts against the movable insert 522 to control the rotation of the movable insert 522. During assembly, the flange sleeve 521 is welded to the flange fixing plate 53, and the free end of the rocker arm 51, i.e., the smooth rod 511, is sleeved in the movable insert 522.

[0038] The screw 71 includes a handle 711, a rotating ring 712, and a lead screw 713 connected in sequence.

[0039] The base 73 includes a base threaded sleeve 731 and a base fixing plate 732.

[0040] The pressure seat 72 includes: a pressure seat screw sleeve 721, a pressure seat screw sleeve 722, a fastening washer 723, a circular washer 724, a pressure seat screw 725, a pressure seat nut 726, a rotating bearing 727, a bearing seat 728, and a fixing plate 729. The rotating bearing 727 is built into the bearing seat 728. The pressure seat screw 725 passes through the bearing seat 728 and the fixing plate 729 in sequence and is locked by the pressure seat nut 726. After assembly, the pressure seat screw sleeve 721, the pressure seat screw sleeve 722, the fastening washer 723, and the circular washer 724 are sequentially sleeved and fixed to the front threaded end of the lead screw 713. The optical shaft of the lead screw 713 is mounted on the rotating bearing 727.

[0041] The left square tube support arm 10, the right square tube support arm 20, the left clamping square tube arm 30, and the right clamping square tube arm 40 are all square tubes.

[0042] When using it, follow these steps:

[0043] 1) Determine the width and adjust the spacing between the support arms:

[0044] Based on the width of the wall 100 of the wall panel 110 to be bonded, the operator rotates the handle 712 of the first adjusting screw assembly 70 and the second adjusting screw assembly 80, driving the screw 71 to rotate relative to the pressure seat 72 fixed on the left square support arm 10 and the base 73 fixed on the right square support arm 20. Since the screw 71 engages with the threaded hole of the base 73, rotating the screw 71 will drive the left square support arm 10 and the right square support arm 20 to move relative to or towards each other, thereby precisely and parallelly adjusting the distance between them to adapt to the width of the wall 100. The parallel arrangement of the two adjusting screw assemblies ensures the stability and parallelism of the adjustment process.

[0045] 2) Positioning support arm:

[0046] Place the entire fastener with the adjusted spacing at the wall frame 120 where the wall panel 110 needs to be bonded, so that the bottom ends of the left through support arm 10 and the right through support arm 20 are firmly supported at appropriate positions on both sides of the wall frame 120.

[0047] 3) Initial placement of the clamping arm and wall panel 110:

[0048] Place the pre-applied adhesive wall panel 110 that needs to be temporarily fixed in the preset position of the wall frame 120, and place the left clamping square tube arm 30 and the right clamping square tube arm 40 on the left and right outer surfaces of the wall panel 110 to be fixed, respectively.

[0049] 4) Adjust and apply parallel clamping force:

[0050] The operator rotates the rocker arm 51 of the left clamping adjusting screw assembly 50 and the right clamping adjusting screw assembly 60 respectively. The threaded rod of the rocker arm 51 rotates through the threaded sleeve 11 fixed to the top of the support arm 10. The rotational motion of the rocker arm 51 is converted into the axial movement of its free end, i.e., the smooth rod 511, within the live flange 52, i.e., feed or retraction. Since the free end of the rocker arm 51 is inserted into the movable insert 522, and the flange sleeve 521 of the live flange 52 is firmly connected to the left clamping square arm 30 through the flange fixing plate 53 and the fixing screw 54, the axial movement of the rocker arm 51 will directly push or pull the entire left clamping square arm 30, and the same applies to the right side.

[0051] Because the left square support arm 10 is rotatably connected to the left clamping square arm 30 via the rotating shaft, i.e., the live flange 52, of the clamping adjusting screw assembly 50, when the rocker arm 51 drives the left clamping square arm 30 to move, the left clamping square arm 30 only performs a parallel movement of clamping inward or releasing outward, without deflection; the same applies to the right side.

[0052] The operator continuously rotates the rocker arms 51 on both sides, driving the left clamping square arm 30 and the right clamping square arm 40 to move inward synchronously and parallel until their inner planes are in close and uniform contact with and pressed against the two outer surfaces of the wall panel 110, applying a stable and evenly distributed clamping force.

[0053] 5) Fixing, waiting, and disassembling:

[0054] After applying uniform pressure to fix the wall panel 110 with the left clamping square arm 30 and the right clamping square arm 40, maintain this state and wait for the adhesive on the back of the wall panel 110 to solidify. After the adhesive has solidified, rotate the rocker arm 51 of the left clamping adjusting screw assembly 50 and the right clamping adjusting screw assembly 60 in the opposite direction to move the left clamping square arm 30 and the right clamping square arm 40 outward in parallel, releasing the wall panel 110. Then, as needed, rotate the rocker arm 51 of the left clamping adjusting screw assembly 50 and the right clamping adjusting screw assembly 60 in the opposite direction to reduce the distance between the support arms, making it easier to store or move to the next work station.

[0055] As can be seen from the above, this new type of device ensures that a large area of ​​parallel clamping force is applied to both sides of the decorative panel during clamping, which effectively prevents the hollowing phenomenon caused by excessive local pressure in the adhesive layer and the warping and deformation of the panel, and significantly improves the flatness and bonding firmness of the decorative panel. At the same time, the screw adjustment method is convenient and efficient to operate, which greatly saves manpower and time costs, and can be used for temporary fixing of the surface layer of decorative wall panels of different widths.

[0056] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on the utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
