Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile technology, specifically relating to a quick-assembly aluminum profile connection structure. Background Technology

[0002] Aluminum profiles are aluminum alloy materials produced through extrusion. They have standardized cross-sectional shapes and dimensions and pre-fabricated grooves for easy installation of connectors. They are commonly used in frames or structural components in industries such as industry, construction, and machinery. Built-in connectors, as components specifically designed to connect aluminum profiles, are usually hidden inside the profile or in the groove, enabling rapid assembly, structural stability, and a clean appearance. One type of connector has a wedge-shaped clamping plate connected to one end of a screw, and a circular plate screwed to the outer wall of the other end to embed into a pre-set circular hole in the side wall of the aluminum profile. The wedge-shaped clamping plate is then inserted into the groove of another aluminum profile. By rotating the hexagonal groove at the top of the screw, the vertical movement of the wedge-shaped clamping plate is controlled, achieving the tension clamping of the two profile sections.

[0003] In existing aluminum profile connectors, after the circular plate is embedded in the circular hole opened on the profile, the screw and the hexagonal groove at its top are also located inside the slide groove to maintain its built-in concealed feature. However, the narrow sidewalls of the slide groove will block the rotation angle of the wrench (the rotation angle is usually difficult to exceed 45°), and the wrench needs to be repeatedly inserted and removed and the position adjusted to complete the tightening, resulting in low operating efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly aluminum profile connection structure that allows for side-operation angle adjustment (rather than top-operation) via a transverse groove. The large diameter of the circular plate provides ample space, avoiding interference from the sidewalls of the aluminum profile slide. This allows for greater rotation angles of the composite rod mechanism, while the operating groove ensures that the tool can find a point of force application at different stages of rotation. Furthermore, the circular plate remains embedded in the circular hole of the aluminum profile, and the composite rod mechanism is concealed within the slide, maintaining a neat and hidden appearance.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A quick-assembly aluminum profile connection structure includes a circular plate that fits into a pre-drilled hole in the aluminum profile. A through transverse groove is radially formed in the center of one side of the circular plate. A composite rod mechanism is provided in the center of the circular plate. The composite rod mechanism includes a screw and an adjusting rod at its top. Three operating grooves are evenly formed in the circumferential direction on the side wall of the adjusting rod.

[0007] The transverse groove is symmetrically provided with connecting plates integrally formed with the circular plate at both ends.

[0008] The axial width of the connecting plate is 1 / 2 of the width of the transverse groove.

[0009] The circular plate has a through hole and a threaded hole arranged coaxially.

[0010] The through hole is used for the adjustment rod to pass through, and the threaded hole is threadedly engaged with the screw.

[0011] The bottom of the screw is rotatably connected to a wedge-shaped clamp, and the working surface of the wedge-shaped clamp has a trapezoidal structure that is adapted to the groove of the aluminum profile.

[0012] The technical effects achieved by this utility model are as follows: the side operating angle adjustment is achieved by the horizontal groove (instead of the top), and the large diameter of the circular plate provides ample space, avoiding interference from the side wall of the aluminum profile slide. This allows for a larger angle of rotation of the composite rod mechanism, while the operating groove ensures that the tool can find a point of force application at different stages of rotation. Furthermore, the circular plate is still embedded in the round hole of the aluminum profile, and the composite rod mechanism is hidden in the slide, maintaining a neat and concealed appearance.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figure 1-3As shown, a quick-assembly aluminum profile connection structure includes a circular plate 1 that fits into a pre-drilled hole in the aluminum profile. A through transverse groove 101 is radially formed in the center of one side of the circular plate 1. Connecting plates 103, integrally formed with the circular plate 1, are symmetrically arranged at both ends of the transverse groove 101. The axial width of the connecting plates 103 is half the width of the transverse groove 101. A composite rod mechanism 104 is provided at the center of the circular plate 1. The composite rod mechanism 104 includes a screw 104a and a... The top of the adjusting rod 104b has a circular plate 1 with a coaxial through hole 102a and a threaded hole 102b. The through hole 102a is used for the adjusting rod 104b to pass through, and the threaded hole 102b is threaded with the screw 104a. The side wall of the adjusting rod 104b is evenly provided with three operating grooves 105 along the circumference. The bottom of the screw 104a is rotatably connected to a wedge-shaped clamping plate 106. The working surface of the wedge-shaped clamping plate 106 is a trapezoidal structure adapted to the groove of the aluminum profile.

[0020] According to the above structure, the circular plate 1 is embedded in the pre-drilled circular hole on the aluminum profile, and the wedge-shaped clamping plate 106 is simultaneously embedded in the groove of another aluminum profile. At this time, the composite rod mechanism 104 is located in the sliding groove of the aluminum profile, with a hidden built-in design. A small wrench or screwdriver or other tool is inserted into the operating groove 105 from the horizontal groove 101, and then the tool is rotated horizontally with the composite rod mechanism 104 as the axis. One end of the tool drives the adjusting rod 104b to rotate through the engagement with the operating groove 105. The adjusting rod 104b drives the screw 104a to rotate, which can make itself and the wedge-shaped clamping plate 106 move up and down. The through hole 102a allows the adjusting rod 104b to pass through. The operating groove 105 is long and narrow, which can ensure that even after the adjusting rod 104b moves up, part of the operating groove 105 is still exposed in the horizontal groove 101.

[0021] Furthermore, each time the tool rotates, one operating groove 105 will face the end of the transverse groove 101. At this time, the tool is pulled out and inserted into another operating groove 105 from the other end of the transverse groove 101, and continues to rotate. The three operating grooves 105 are evenly distributed on the circumference, with 120° between each two grooves. That is, the tool can rotate the adjusting rod 104b by 120° each time. The upward movement of the composite rod mechanism 104 can clamp the two aluminum profiles together. The connecting plate 103 provides support for the structural strength of the circular plate 1, preventing a significant decrease in the strength of the middle part of the circular plate 1 due to the transverse groove 101. Here, "axial" refers to the depth direction of the transverse groove 101 in this structure. If the horizontal groove width of the transverse groove 101 is W, then the axial width of the connecting plate 103 is W / 2, so that the two ends of the transverse groove 101 still maintain a half gap, avoiding affecting the rotation of the tool.

[0022] The working principle of this utility model is as follows: a circular plate 1 is embedded into a pre-drilled circular hole on an aluminum profile, and a wedge-shaped clamping plate 106 is simultaneously embedded into a groove in another aluminum profile. At this time, the composite rod mechanism 104 is located in the sliding groove of the aluminum profile, with a hidden built-in design. A small wrench or screwdriver or other tool is inserted into the operating groove 105 from the horizontal groove 101, and then the tool is rotated horizontally with the composite rod mechanism 104 as the axis. One end of the tool drives the adjusting rod 104b to rotate through the engagement with the operating groove 105. The adjusting rod 104b drives the screw 104a to rotate, which allows itself and the wedge-shaped clamping plate 106 to move up and down. The through hole 102a allows the adjusting rod 104b to pass through. The operating groove 105 is elongated, which ensures that even after the adjusting rod 104b moves up, part of the operating groove 105 is still exposed in the horizontal groove 101.

[0023] Furthermore, each time the tool rotates, one operating groove 105 will face the end of the transverse groove 101. At this time, the tool is pulled out and inserted into another operating groove 105 from the other end of the transverse groove 101, and continues to rotate. The three operating grooves 105 are evenly distributed on the circumference, with 120° between each two grooves. That is, the tool can rotate the adjusting rod 104b by 120° each time. The upward movement of the composite rod mechanism 104 can clamp the two aluminum profiles together. The connecting plate 103 provides support for the structural strength of the circular plate 1, preventing a significant decrease in the strength of the middle part of the circular plate 1 due to the transverse groove 101. Here, "axial" refers to the depth direction of the transverse groove 101 in this structure. If the horizontal groove width of the transverse groove 101 is W, then the axial width of the connecting plate 103 is W / 2, so that the two ends of the transverse groove 101 still maintain a half gap, avoiding affecting the rotation of the tool.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
