Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to an aluminum profile connector kit. Background Technology
[0002] Aluminum profiles are widely used in various industries due to their advantages such as light weight, high strength, ease of processing, and cost-effectiveness. As the core component in aluminum profile assembly, the performance of connectors directly affects the stability of the aluminum profile structure and the installation efficiency.
[0003] Patent publication number CN220286138U discloses a quick-assembly kit for furniture panels, comprising: a six-way connector, connecting bolts, and a splicing rod. The six-way connector has six identical splicing surfaces, adjacent to each other perpendicularly. Each splicing surface has a center-mounted interface hole of the same specification, with internal threads within the interface hole. The connecting bolt includes a bolt head and a bolt body. The bolt head has external threads matching the interface hole, and its thickness is less than the depth of the interface hole. The cross-sectional profile of the splicing rod is the same as the specifications of the splicing surfaces. A insertion hole is located at the center of the end face of the splicing rod, and this insertion hole is interference-fitted with the bolt body of the connecting bolt. Four identical panel slots are symmetrically arranged on the splicing rod, with a positioning screw hole at the end of the middle slot. Through this method, the present invention can reduce the difficulty of assembling furniture panels and improve assembly accuracy.
[0004] The above technical solution uses a positioning boss and positioning groove to achieve the installation angle positioning, and uses positioning screw holes and bolts to limit the connection bolts to achieve installation. However, the above technical solution requires customized profiles with positioning grooves and positioning screw holes, and is not suitable for ordinary profiles on the market. Utility Model Content
[0005] The purpose of this invention is to solve the problems mentioned in the background art by designing an aluminum profile connection kit.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an aluminum profile connecting kit, comprising a profile body, a connecting block, a connecting threaded hole, a connecting stud, a limiting ring groove, a positioning hole, a positioning pin, a limiting threaded hole, a limiting stud, and an opening. The connecting block has a six-sided cubic structure, with a connecting threaded hole in the center of each face of the connecting block. The connecting threaded hole is engaged with a connecting stud, and a limiting ring groove is opened at the rear of the connecting stud. Four positioning holes are respectively arranged in a cross pattern on each face of the connecting block. One to four of the four sides of the profile body are... Each side has a locating pin slidably embedded therein. The front end of the locating pin is inserted into a locating hole, and the rear part of the locating pin has a limiting threaded hole. A limiting stud is inserted into the limiting threaded hole. An opening is made on the profile body. The limiting stud passes through the opening and is squeezed against the limiting ring groove. The diameter of the limiting stud is the same as the width of the limiting ring groove. Under the action of the limiting ring groove and the opening, the limiting stud limits the position of the connecting stud and simultaneously limits the position of the locating pin. The squeezing action of the limiting stud against the limiting ring groove restricts the position and angle of the connecting stud.
[0007] Furthermore, the connecting stud has an external thread at its front, and the connecting stud engages with the connecting threaded hole through the external thread at its front. The diameter of the middle and rear parts of the connecting stud is greater than or equal to the diameter of the hole in the middle part of the profile body, and this part transitions into the hole in the middle part of the profile body.
[0008] Furthermore, the rear end of the connecting stud is provided with a screwing part, which is a hexagonal prism structure.
[0009] Furthermore, the positioning hole is an isosceles triangle structure, and the front end of the positioning pin is provided with a positioning head. The positioning head corresponds to the shape of the positioning hole, and the positioning pin is inserted into the positioning hole through the positioning head.
[0010] Furthermore, the tail of the limiting stud has an internal hexagonal hole.
[0011] Furthermore, the diameter of the opening is the same as the outer diameter of the limiting stud.
[0012] Furthermore, the shape of the positioning pin corresponds to the groove on the side of the profile body.
[0013] Furthermore, the front end of the connecting stud is provided with a tapered surface.
[0014] Furthermore, the thread depths of the connecting external thread and the connecting threaded hole are consistent.
[0015] Beneficial effects:
[0016] This utility model provides an aluminum profile connecting kit with the following advantages: Through its structural design, the device uses a connecting block as the connecting unit. When connecting the profile bodies, first, the connecting stud is screwed into the connecting threaded hole on the connecting block. Then, the hole in the middle of the profile body is aligned with the connecting stud and fitted. Before or after this, one to four positioning pins can be inserted into the slots on the four sides of the profile body. When the connecting block and one end of the profile body are fully aligned, the positioning pin is inserted into the positioning hole. Then, the positioning stud is screwed into the limiting threaded hole, causing the positioning stud to pass through the opening and be pressed against the limiting ring groove on the connecting stud, thereby limiting the connection stud. Furthermore, the connecting stud limits the front-to-back position of the connecting block, the positioning pin limits the torsion of the connecting block, and the inner wall of the hole in the connecting stud and the profile body limits the shearing movement between the profile body and the connecting block. Finally, the connecting block installs and fixes the profile bodies in six directions, achieving the connection between multiple profile bodies. Since this connection kit does not require a custom profile body, it only requires drilling holes in the profile body to adapt to common aluminum profiles on the market. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] Please see Figure 1-4 This utility model provides a technical solution: an aluminum profile connecting kit, including a profile body 1, a connecting block 2, a connecting threaded hole 3, a connecting stud 4, a limiting ring groove 5, a positioning hole 6, a positioning pin 7, a limiting threaded hole 8, a limiting stud 9, and an opening 10. The connecting block 2 has a six-sided cubic structure, with a connecting threaded hole 3 in the center of each face of the connecting block 2. The connecting threaded hole 3 is engaged with the connecting stud 4, and a limiting ring groove 5 is opened at the rear of the connecting stud 4. Four positioning holes 6 are respectively arranged in a cross pattern on each face of the connecting block 2. Positioning pins 7 are slidably embedded in one to four of the four sides of the profile body 1 (the slidable embedding of positioning pins 7 in one to four sides means that at least one of the four sides has a positioning pin 7 slidably embedded, and there may also be two). Each side is fitted with a positioning pin 7 (or possibly three sides, or four sides). The front end of the positioning pin 7 is inserted into the positioning hole 6, and the rear of the positioning pin 7 has a limiting threaded hole 8. A limiting stud 9 is inserted into the limiting threaded hole 8. The profile body 1 has an opening 10. The limiting stud 9 passes through the opening 10 and is squeezed against the limiting ring groove 5. The diameter of the limiting stud 9 is the same as the width of the limiting ring groove 5. Under the action of the limiting ring groove 5 and the opening 10, the limiting stud 9 limits the position of the connecting stud 4 and simultaneously limits the position of the positioning pin 7. The squeezing action of the limiting stud 9 against the limiting ring groove 5 restricts the position and angle of the connecting stud 4, thereby preventing loosening and avoiding shaking of the connecting stud 4.
[0026] In this utility model, the front part of the connecting stud 4 is provided with a connecting external thread 11. The connecting stud 4 engages with the connecting threaded hole 3 through the connecting external thread 11 at the front. The diameter of the middle and rear parts of the connecting stud 4 is greater than or equal to the diameter of the through hole in the middle part of the profile body 1, and this part transitions with the hole in the middle part of the profile body 1, thereby making the connecting stud 4 and the through hole in the middle part of the profile body 1 fit tightly together, avoiding shearing movement between the profile body 1 and the connecting block 2.
[0027] In this utility model, the rear end of the connecting stud 4 is provided with a screwing part 12, which is a hexagonal prism structure. The screwing part 12 facilitates the use of a socket or wrench to screw the connecting stud 4.
[0028] In this utility model, the positioning hole 6 is an isosceles triangle structure, and the positioning pin 7 has a positioning head 13 at the front end. The positioning head 13 and the positioning hole 6 correspond in shape. The positioning pin 7 is inserted into the positioning hole 6 through the positioning head 13, thereby locking the torsion angle between the profile body 1 and the connecting block 2. The positioning head 13 can also be other shapes, such as circles or other polygons.
[0029] In this utility model, the tail of the limiting stud 9 has an internal hexagonal hole 14, which facilitates the tightening of the limiting stud 9 with an internal hexagonal wrench. At the same time, the internal hexagonal hole 14 is a recessed structure, which does not affect the overall appearance of the device.
[0030] In this invention, the diameter of the opening 10 is the same as the outer diameter of the limiting stud 9, thereby limiting the position of the limiting stud 9. Furthermore, the limiting stud 9 limits the limiting annular groove 5 of the connecting stud 4 and the positioning pin 7.
[0031] In this utility model, the shape of the positioning pin 7 corresponds to the groove on the side of the profile body 1, so that the positioning pin 7 slides tightly in the groove on the side of the profile body 1, which plays a limiting role in positioning the positioning pin 7 and prevents the positioning pin 7 from shaking or loosening.
[0032] In this utility model, the front end of the connecting stud 4 is provided with a tapered surface 15, which facilitates the alignment of the connecting stud 4 and the connecting threaded hole 3 when installing the connecting stud 4.
[0033] In this invention, the thread depths of the connecting external thread 11 and the connecting threaded hole 3 are consistent, thereby limiting the screwing depth of the connecting stud 4 by matching the connecting external thread 11 and the connecting threaded hole 3.
[0034] In this implementation plan:
[0035] This connecting kit uses connecting block 2 as the connecting unit. When connecting the profile body 1, first screw the connecting stud 4 into the connecting threaded hole 3 on the connecting block 2. Then, align the hole in the middle of the profile body 1 with the connecting stud 4 and put it on. Before or after this, insert one to four locating pins 7 into the slots on one to four sides of the profile body 1. When the connecting block 2 and one end of the profile body 1 are fully aligned, insert the locating pin 7 into the locating hole 6. Then, screw the limiting stud 9 into the limiting threaded hole 8 so that the limiting stud 9 passes through the opening 10. The connecting stud 4 is pressed against the limiting annular groove 5, thereby limiting the connecting stud 4. The connecting stud 4 further limits the front and rear positions of the connecting block 2. The positioning pin 7 limits the torsion of the connecting block 2. The connecting stud 4 and the inner wall of the hole in the middle of the profile body 1 fit together to limit the shearing movement between the profile body 1 and the connecting block 2, so as to prevent the profile body 1 and the connecting block 2 from being misaligned. Then, the connecting block 2 is used to install and fix the profile body 1 in six directions, realizing the connection between multiple profile bodies 1.
