[0002] Aluminum alloy profiles are materials formed by one-time drawing by a forming machine. They are mostly used in the building materials industry. In addition to their fixing performance, they are also reflected in the supporting structure. For example, when they are used as supports, they are often used on columns or cross braces of infrastructure. When installing, you need to first fix the profile pull-out to the building bodies on both sides with screws, and then clamp the two ends of the profile tube on the two profile pull-outs respectively.

[0003] In order to smoothly connect the two ends of the profile tube to the two profile pull-codes, the diameter of the profile tube is often larger than the outer diameter of the profile pull-code (clearance fit). Although the profile tube can be smoothly connected, after the profile tube is connected, the clearance fit between the tube cavities at both ends and the pull-codes will cause shaking, causing structural instability when subjected to force during loading, affecting strength.

[0007] The locking assembly also includes a second locking rod connected between the locking seat and the first locking rod. The locking assembly also includes a profile tube located outside the profile body. The profile tube is rectangular, and the four sides of the profile tube are located outside the four sides of the profile body. When the first locking rod is locked outwardly on the profile tube along the active gap, the locking seat is driven to move along the active gap through the second locking rod, and a locking force is provided to the first locking rod.

[0008] As a further preferred embodiment, a first groove is formed on both the first protruding portion and the second protruding portion, and a groove width of the first groove is close to a diameter of the first locking rod.

[0009] As a further preferred embodiment, the bending angle between the two ends of the first locking rod and the bent portion is ninety degrees, the outer end of the locking hole is connected to the first groove, and the bent portions at the two ends of the first locking rod are inserted into the locking hole through the first groove.

[0010] As a further preferred embodiment, a slot is provided on the outer surface of the locking seat, and the slot is clamped on the first locking rod.

[0011] As a further preferred embodiment, each outer surface of the profile body is provided with a second groove along its molding direction, the number of the second locking rods is consistent with the number of the second grooves, a second locking rod is connected in each of the second grooves, two third grooves are provided along the end surfaces of the four sides of the profile body, and each of the second grooves corresponds to a third groove, one end of the third groove is communicated with the second groove, and the other end of the third groove is communicated with the inner surface of the profile body;

[0012] The locking assembly also includes a steel wire, one end of which is connected to the first locking rod along the second groove and the third groove, and the other end of the steel wire enters the assembly hole on the same side and is connected to the curved portion on the same side.

Therefore, after the profile tube is combined with the profile body on the building, the shaking can be reduced and the strength can be improved. When the four locking screws are locked into the four assembly holes, the inner ends will be used to push against the two chamfers at the same time. Since the two chamfers are respectively located on the two bent portions, and the bent portions are the end bent portions of the first locking rod, after the four locking screws are driven into the four assembly holes to fix the profile body to the building body, the inner ends will be used to squeeze the chamfers to make the bent portions move outward along the locking holes where they are located, and the bent portions will push the first locking rods where they are located to move outward. Since two bent portions are provided at both ends of the same first locking rod, and the chamfers at the inner ends of the two bent portions are respectively in the two assembly holes, similarly, the bent portions at both ends of the four first locking rods are respectively in the two assembly holes. Therefore, when the four locking screws are driven into the four assembly holes, the eight bent portions can be moved outward along the tightening holes where they are located, which is equivalent to making the four first locking rods move toward the four inner surface directions of the profile tube respectively, so as to achieve the purpose of completely locking the profile tube on the profile body and completely connecting it with the building body.

DETAILED DESCRIPTION

[0027] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0028] In one embodiment, if Figure 1-Figure 8 As shown:

[0029] The present embodiment provides an aluminum profile, including a profile body 1, the cross-sectional shape of the profile body 1 is square, and is used as the profile puller mentioned in the back technology. The four corners of the profile body 1 are provided with raised parts 2, and the raised parts 2 on the same corner include a first raised part 3 and a second raised part 4 that are symmetrical and overlap each other. The first raised parts 3 or the second raised parts 4 at both ends of the same side of the profile body 1 are symmetrical to each other. Each raised part 2 is provided with an assembly hole 5 along the forming direction of the profile body 1, so that the four assembly holes 5 are arranged on the four corners of the profile body 1. The above-mentioned raised part 2, the assembly hole 5 and the two-part structure of the raised part 2 are all obtained by the profile body 1 being extruded by the mold of the molding machine head at one time. When it is made into a puller, it is cut by a cutting machine and cut into Figure 1As shown, in addition, it is processed twice, and two locking holes 6 are opened in each assembly hole 5 by an electric drill, the inner ends of the two locking holes 6 deviate from the hole center of the assembly hole 5, and the outer ends of the two locking holes 6 respectively penetrate the outer sides of the first protruding part 3 and the second protruding part 4; in addition, four sets of locking components 7 are arranged on the profile body 1, and the locking components 7 include first locking rods 8 distributed on the outer sides of the four sides of the profile body 1, the first locking rods 8 are parallel to the outer side of one side of the profile body 1, and the two ends of the first locking rods 8 are respectively provided with bending parts 9, and the two bending parts 9 are respectively inserted into the locking holes 6 of the two protruding parts 2 on the same side, and the bending parts 9 are provided with chamfers 10 on the opposite surfaces in the locking holes 6, and the locking components 7 also include locking screws 11 matched on each locking hole 6; in addition, active gaps 12 are formed between the four sides of the profile body 1 and the four first locking rods 8, and a locking seat 13 is provided in each active gap 12;

[0030] The locking assembly 7 also includes a second locking rod 14 connected between the locking seat 13 and the first locking rod 8. The locking assembly 7 also includes a profile tube 15 located on the periphery of the profile body 1. The profile tube 15 is rectangular, and the four sides of the profile tube 15 are located outside the four sides of the profile body 1. When the first locking rod 8 is locked outward on the profile tube 15 along the active gap 12, the locking seat 13 is driven to move along the active gap 12 through the second locking rod 14, and a locking force is provided to the first locking rod 8.

[0031] During assembly, the profile body 1 is placed on the building, the pipe mouth of the profile tube 15 is sleeved on the profile body 1, and the hand drill with an extended drill bit pushes the four locking screws 11 into the four assembly holes 5 respectively, and the four locking screws 11 are drilled on the building along the four assembly holes 5. The profile body 1 is equivalent to a pull code fixed on the building, and the four sides of the profile body 1 are equivalent to the internal connection of the profile tube 15. That is, in order to fix the profile tube 15 on the building, it is only necessary to sleeve one end of the profile tube 15 on the profile body 1. In addition to being directly sleeved on the profile body 1 and installed, the locking components 7 on the four sides of the profile body 1 will also increase the thickness of the four sides of the profile body 1, which is equivalent to forming a locking effect on the four inner surfaces of the profile tube 15. Therefore, after the profile tube 15 is combined with the profile body 1 on the building, the shaking can be reduced and the strength can be improved. Of course, when the profile tube 15 is used as a crossbeam or a cross brace, in order to improve its strength and prevent its deformation, two profile bodies 1 need to be symmetrically arranged on the building body, and a support is arranged at each end of the profile tube 15. The specific principle is as follows: when the four locking screws 11 are locked into the four assembly holes 5, the inner ends will be used to push against the two chamfers 10 at the same time. Since the two chamfers 10 are respectively located on the two curved portions 9, and the curved portions 9 are the end curved portions of the first locking rod 8, after the four locking screws 11 are driven into the four assembly holes 5 to fix the profile body 1 to the building body, the inner ends will be used to squeeze the chamfers 10 so that the curved portions 9 are along the corresponding curved portions. The locking hole 6 moves outward, and the first locking rod 8 is pushed outward by the curved portion 9. Since two curved portions 9 are provided at both ends of the same first locking rod 8, and the chamfers 10 at the inner ends of the two curved portions 9 are respectively in the two assembly holes 5, similarly, the curved portions 9 at both ends of the four first locking rods 8 are respectively in the two assembly holes 5. Therefore, when the four locking screws 11 are driven into the four assembly holes 5, the eight curved portions 9 can be moved outward along the locking holes 6, which is equivalent to making the four first locking rods 8 move toward the four inner surfaces of the profile tube 15, respectively, so as to achieve the purpose of completely locking the profile tube 15 on the profile body 1 and completely connecting it with the building body.

[0032] A first groove 16 is formed on the first protruding portion 3 and the second protruding portion 4 . The width of the first groove 16 is close to the diameter of the first locking rod 8 .

[0033] The bending angle between the two ends of the first locking rod 8 and the bent portion 9 is ninety degrees, the outer end of the locking hole 6 is connected to the first groove 16, and the bent portions 9 at the two ends of the first locking rod 8 are inserted into the locking hole 6 through the first groove 16. Since the protrusions 2 are provided at four places and distributed at the four corners of the profile body 1, and are formed at one time with the profile body 1, the strength of the profile body 1 is improved. When the profile body 1 bears the weight of the profile tube 15, the reinforcement effect of the protrusions 2 can prevent deformation. Since the first groove 16 is provided on the protrusion 2, and the bent portions 9 at the two ends of the first locking rod 8 are inserted into the assembly hole 5 along the locking hole 6 and are confined in the first groove 16, the strength of the bent portions 9 at the two ends of the first locking rod 8 is improved.

[0034] A clamping groove 17 is disposed on the outer surface of the locking seat 13 , and the clamping groove 17 is clamped on the first locking rod 8 . A second groove 18 is provided on each outer surface of the profile body 1 along its forming direction. The number of second locking rods 14 is consistent with the number of second grooves 18. A second locking rod 14 is connected to each second groove 18. Two third grooves 19 are provided along the end faces of the four sides of the profile body 1, and each second groove 18 corresponds to a third groove 19. One end of the third groove 19 is connected to the second groove 18, and the other end of the third groove 19 is connected to the inner surface of the profile body 1. The locking seat 13 is equivalent to a pad in the middle position of the first locking rod 8. When the first locking rod 8 moves outward, the locking seat 13 will also move with it. When the first locking rod 8 is pressed against the tube cavity surface of the profile tube 15 to lock the profile tube 15, the locking seat 13 supports the middle area of ​​the first locking rod 8 outward to prevent the middle area of ​​the first locking rod 8 from deformation. In order to enable the locking seat 13 to move outward with the first locking rod 8, as shown in the following example: Figures 4 to 8As shown, the locking assembly 7 also includes a steel wire 20, one end of which is connected to the first locking rod 8 along the second groove 18 and the third groove 19, and the other end of the steel wire 20 enters the assembly hole 5 on the same side and is connected to the curved portion 9 on the same side. The locking screw 11 is driven into the assembly hole 5, and the inner end is used to push against the chamfer 10 to move the curved portion 9 outward along the locking hole 6 where it is located, and at the same time, the four first locking rods 8 are moved outward and pressed against the tube cavity surface of the profile tube 15 to lock the profile tube 15. The curved portion 9 also pulls the steel wire 20 to move outward, and the steel wire 20 drives the second locking rod 14 to deflect outward. The deflection of the second locking rod 14 pushes the locking seat 13 to move outward along the active gap 12, and the card slot 17 is used to provide an outward thrust to the middle area of ​​the first locking rod 8, so as to further improve the locking force of the first locking rod 8 on the inner surface of the tube cavity of the profile tube 15, and prevent the first locking rod 8 from deforming. To sum up, whether it is the first locking rod 8 providing the locking force to the inner wall of the tube cavity of the profile tube 15, or the second locking rod 14 pushing the locking seat 13 to provide the locking force to the middle area of ​​the first locking rod 8, when the locking screw 11 is driven into the assembly hole 5 to fix the profile body 1 to the building body, one fixing action achieves two locking effects and is easy to operate.

[0035] In order to prevent the steel wire 20 from breaking, Figure 7 , Figure 8 As shown, a first rounded corner 21 is provided at a connection between the third groove 19 and the inner surface of the profile body 1 , and a second rounded corner 22 is provided at a connection between the third groove 19 and the second groove 18 .

[0036] A stepped groove 23 is opened inward along the end of the profile body 1, and the outer end of the stepped groove 23 is connected to the second groove 18. The steel wire 20 passes through the groove surface of the second groove 18 and is supported on the groove surface of the second groove 18. The stepped groove 23 provides a movement path for the steel wire 20 to ensure smooth movement of the steel wire 20.

[0037] like Figure 4 As shown, a recessed groove 24 is provided on the curved portions 9 at both ends of the first locking rod 8 along the chamfer 10, and one end of the steel wire 20 connected to the curved portion 9 is inserted into the recessed groove 24. When the locking screw 11 is driven into the assembly hole 5 to fix the profile body 1 on the building, the inner end of the locking screw 11 presses against the chamfer 10 and continues to drill. Since the connection between the steel wire 20 and the curved portion 9 is located in the recessed groove 24 of the chamfer 10, in addition to pushing the curved portion 9 outward, the inner end of the locking screw 11 is prevented from wearing and damaging the connection section of the steel wire 20 on the curved portion 9.
