Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PVC special-shaped materials, in particular to a PVC special-shaped material with double-sided V-shaped grooves. Background Art
[0002] PVC, also known as polyvinyl chloride, is obtained by polymerizing vinyl chloride. PVC material offers advantages such as tensile strength, bending strength, compression strength, impact resistance, wear resistance, a smooth surface, and bright color. PVC profiles are made by extruding PVC resin at high temperatures after adding various functional additives. PVC profiles are categorized into two types based on performance: rigid and flexible. Rigid PVC profiles are primarily used in construction, such as PVC doors and windows, PVC flooring, and PVC pipes.
[0003] Traditional methods for joining PVC profiles often rely on gluing, simple mortise and tenon joints, or additional metal fasteners. While relatively simple to use, gluing has limited bond strength. Over time and due to environmental factors, the glue can age and fail, causing the joints to loosen and compromising the stability of the overall structure. For PVC profiles with simple mortise and tenon joints, even the slightest deviation during processing and installation can lead to loose joints and gaps, which not only affects the aesthetics but also reduces the overall strength of the structure. Utility Model Content
[0004] The purpose of the utility model is to solve the problem in the prior art that PVC profiles cannot be accurately and tightly spliced, and to propose a PVC profile with double-sided V-grooves.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A PVC profile with double-sided V-grooves, comprising a PVC profile body, a V-groove on one side of the PVC profile body, a V-shaped clamping block mounted on the other side of the PVC profile body, the V-shaped clamping block being engaged with the V-groove, and a through hole being formed in the PVC profile body;
[0007] Also includes:
[0008] Mounting parts, which are used to preliminarily fix the PVC profile body for splicing and installation;
[0009] Fasteners are used to reinforce and disassemble the PVC profile body for splicing and installation.
[0010] Preferably, the mounting member comprises:
[0011] A snap-fit groove, the snap-fit groove being provided on two adjacent side walls of the V-shaped snap-fit groove;
[0012] A groove is provided on two adjacent side walls of the V-shaped block;
[0013] a spring fixed on the inner wall of the groove;
[0014] A clamping block, the clamping block is fixed on the spring and is clamped with the clamping groove;
[0015] a resisting rod fixed to the inner surface of the clamping block;
[0016] A through groove is provided on the V-shaped block and is communicated with the through hole.
[0017] Preferably, the end side of the interference rod is provided with a curved surface.
[0018] Preferably, the fastener comprises:
[0019] an embedded block, the embedded block being fixed in the through hole;
[0020] a screw, the screw being threadedly connected within the embedded block;
[0021] A sliding rod, wherein the sliding rod is threadedly sleeved on the screw rod, the sliding rod is placed in the through hole and slides, the sliding rod is hollow, and is provided with an external thread that matches the screw rod thread;
[0022] A resistance ball is fixed at the end of the slide bar.
[0023] Preferably, the interference ball matches the arc-shaped surface of the interference rod.
[0024] Preferably, the fastener further comprises:
[0025] An embedded groove is provided at the end of the screw and is arranged in a hexagonal shape.
[0026] Compared with the prior art, the present invention has the following advantages:
[0027] This utility model achieves splicing installation by providing matching V-shaped blocks and V-shaped slots. During installation, the connecting block mounted on the V-shaped block encounters moderate compression from the sidewalls of the V-shaped slot, which in turn causes the spring to compress and deform, driving the connecting block back into the groove to smoothly traverse the obstacle. Once the connecting block reaches a position that matches the slot, the spring instantly releases energy due to its elastic force, pushing the connecting block rapidly outward and achieving a tight snap connection with the slot. This series of actions seamlessly connects, ensuring a tight, gap-free splicing installation and ultimately ensuring the overall strength of the PVC profile body during splicing.
[0028] 2. The utility model inserts an external hexagonal wrench into the through hole and clamps it into the embedded groove on the top surface of the screw. Turning the hexagonal wrench drives the screw to rotate and drives the interference ball at the end of the slide rod to slide through the action of the thread. When the interference ball contacts the arc surface of the interference rod, it will exert an additional pressure on the clamping block, making the clamping between the V-shaped clamping block and the V-shaped clamping groove tighter, thereby effectively strengthening the splicing and installation of the PVC profile body, avoiding loosening at the splicing point, and improving the stability of the overall structure.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all the embodiments.
[0037] Reference Figure 1-Figure 5 A PVC profile with a double-sided V-groove includes a PVC profile body 1, a V-shaped groove 2 is opened on one side of the PVC profile body 1, a V-shaped block 5 is installed on the other side of the PVC profile body 1, the V-shaped block 5 is clamped with the V-shaped groove 2, and a through hole 3 is opened in the PVC profile body 1.
[0038] The PVC special-shaped material with double-sided V-shaped grooves also includes a mounting piece and a fastener.
[0039] The mounting piece is used to initially fix the PVC profile body 1 for splicing and installation. The mounting piece includes a clamping groove 4, a groove 51, a spring 52, a clamping block 53, a contact rod 54, and a through groove 55. The clamping groove 4 is provided on the adjacent side walls of the V-shaped clamping groove 2, the groove 51 is provided on the adjacent side walls of the V-shaped clamping block 5, the spring 52 is fixed to the inner wall of the groove 51, and the clamping block 53 is fixed to the spring 52. The spring 52 provides elasticity, allowing the clamping block 53 to move flexibly to adapt to different installation requirements. The clamping block 53 can move with the elastic force of the spring 52, allowing it to closely cooperate with the clamping groove 4 to achieve stable clamping. The clamping block 53 is clamped to the clamping groove 4, the contact rod 54 is fixed to the inner surface of the clamping block 53, and the end side of the contact rod 54 is provided with an arc surface. The through groove 55 is provided on the V-shaped clamping block 5 and is connected to the through hole 3.
[0040] The fasteners are used to reinforce the disassembly and splicing of the PVC profile body 1. The fasteners further pressurize the clamping block 53, making the entire splicing structure more stable, able to effectively resist external forces, avoid loosening of the splicing joints, and greatly improve the firmness of the splicing installation of the PVC profile body. The fastener includes an embedded block 6, a screw 7, a sliding rod 8, a contact ball 9 and an embedded groove 71. The embedded block 6 is fixed in the through hole 3, and the embedded block 6 provides a stable support point so that the subsequent screw 7 and sliding rod 8 can be stably installed. The screw 7 is threadedly connected to the embedded block 6, and the sliding rod 8 is threadedly sleeved on the screw 7. The sliding rod 8 is placed in the through hole 3 and slides. The sliding rod 8 is hollow and has an external thread that matches the thread of the screw 7. The contact ball 9 is fixed at the end of the sliding rod 8. The contact ball 9 matches the arc surface of the contact rod 54, so that uniform pressure distribution can be provided during the tightening process, reducing the risk of damage to the PVC profile body 1. The embedded groove 71 is opened at the end of the screw 7. The embedded groove 71 is hexagonal in shape. A convenient interface is provided through the embedded groove 71, so that a wrench or similar tool can be used to rotate the screw 7, thereby conveniently performing tightening or disassembly operations.
[0041] It should be noted that the shape of the embedded groove 71 matches that of the hexagonal wrench. As shown in the figure, the hexagonal wrench can be inserted into the embedded groove 71 during disassembly to control the rotation of the screw 7.
[0042] The functional principle of this utility model can be explained through the following operation modes:
[0043] When splicing the PVC profile body, the V-shaped block on one side is inserted into the V-shaped groove on the other side. During the insertion process, the clamping block 53 on the V-shaped block will be squeezed by the side wall of the V-shaped groove, causing the spring 52 to compress and the clamping block 53 to retract into the groove 51. When the clamping block 53 moves to the position corresponding to the clamping groove 4, under the elastic force of the spring 52, the clamping block 53 quickly pops out and clamps with the clamping groove 4, thereby achieving preliminary fixation of the PVC profile body.
[0044] Then, the hexagonal wrench matching the embedded groove 71 is inserted into the through hole 3 and clamped into the embedded groove 71 on the top surface of the screw 7. Then, the hexagonal wrench is turned to drive the screw 7 to rotate. Due to the threaded matching relationship between it and the slide rod 8, the slide rod 8 will be driven to slide in the through hole 3. When the interference ball 9 at the end of the slide rod 8 contacts the arc surface of the interference rod 54 and continues to push, an additional pressure will be applied to the clamping block 53, making the clamping between the clamping block 53 and the clamping groove 4 tighter, thereby effectively strengthening the splicing and installation of the PVC profile body.
[0045] When disassembly is required, the screw rod 7 is rotated in the opposite direction, and the sliding rod 8 drives the contact ball 9 to retreat, releasing the pressure on the contact rod 54 and the clamping block 53. The spring 52 uses its own performance to drive the clamping block 53 to return to the embedded groove 51, so that the clamping block 53 is disengaged from the clamping groove 4, thereby releasing the limit of the V-shaped clamping block from the V-shaped clamping groove, making it easy to pull the V-shaped clamping block out of the V-shaped clamping groove, thereby realizing a convenient disassembly operation.
[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
