Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profiles, in particular to an aluminum profile with adjustable length. Background Art

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Aluminum profiles are usually manufactured in a fixed length. The existing aluminum profiles are too long, which makes them inconvenient to transport. In addition, the fixed length makes it impossible to adjust the length as needed during use, which is not conducive to the installation of the aluminum profiles.

[0003] In the prior art, for example, announcement number CN219692924U proposes an aluminum profile with adjustable length. This technical solution discloses an aluminum profile with adjustable length, comprising: a first aluminum profile, a second aluminum profile being slidably connected to the interior of the first aluminum profile, a plug-in mechanism being provided on the first aluminum profile, the plug-in mechanism comprising a fixed seat, two sliding rods and a pressing assembly, the fixed seat being a hollow cavity with an opening on the bottom side, the bottom side of the fixed seat being fixedly welded to the top wall at one end of the first aluminum profile, a fixed block being fixedly welded to the rear wall of the inner cavity of the fixed seat, a first spring being fixedly bonded to both sides of the fixed block, the two sliding rods being slidably connected to the two side walls of the fixed seat respectively, a connecting seat being fixedly welded to the end of the sliding rod close to the fixed block, and the connecting seat being fixedly bonded to the end of the first spring away from the fixed block. The utility model can achieve the effect of adjusting the length of the aluminum profile, making it easy to ship the aluminum profile during transportation and the length can be adjusted as required, thereby facilitating the installation of the aluminum profile;

[0004] However, in the prior art, when adjusting the length of the aluminum profile, it is necessary to press the pressing block and pull the second aluminum profile at the same time to adjust the length of the aluminum profile, which makes the use of the aluminum profile inconvenient. Moreover, after the length of the aluminum profile is adjusted, the pressing block is exposed to the outside, which makes it easy for people to accidentally touch the pressing block during use, causing the aluminum profile to loosen, thereby reducing the stability of the aluminum profile during use.

[0005] In order to solve the above problems, this application proposes an aluminum profile with adjustable length. Utility Model Content

[0006] The utility model is intended to provide an aluminum profile with adjustable length, which is mainly used to solve the problem that the existing aluminum profile needs to press a pressing block and pull a second aluminum profile at the same time to adjust the length of the aluminum profile, which makes the use of the aluminum profile more inconvenient. In addition, people can easily accidentally touch the pressing block during use, causing the aluminum profile to loosen, thereby resulting in low stability of the aluminum profile during use.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A length-adjustable aluminum profile comprises a first aluminum profile and a second aluminum profile slidably connected to one end of the first aluminum profile, a sliding cavity is provided inside the second aluminum profile, a symmetrical moving block is slidably connected inside the sliding cavity, the top and bottom of the moving block are fixedly connected to a guide block, a guide groove matching the guide block is provided on the inner wall of the sliding cavity, one side of the moving block is fixedly connected to a limiting block, a second aluminum profile is extended from the side of the limiting block away from the moving block, and the limiting block is slidably connected to the second aluminum profile, a plurality of limiting grooves matching the limiting block are provided on both sides of the inner wall of the first aluminum profile, and the limiting grooves are equidistantly distributed in a linear array on both sides of the inner wall of the first aluminum profile, and one side of the inner wall of the sliding cavity is rotatably connected to a driving component that causes the two moving blocks to move synchronously.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the aluminum profile is in use, the driving assembly inside the sliding cavity can be operated to enable the two moving blocks to drive the limit blocks to move simultaneously into the sliding cavity. When the limit blocks are out of the limit groove on the inner wall of the first aluminum profile, the second aluminum profile can be pulled to move outward, thereby adjusting the length of the aluminum profile. After the length of the aluminum profile is adjusted appropriately, the driving assembly can be operated to enable the two moving blocks to move away from each other at the same time. When the limit blocks on the moving blocks are inserted into the limit groove, the second aluminum profile can be limited and the aluminum profile can be used normally.

[0011] 2. Beneficial effect: After the limit block on the moving block is disengaged from the limit slot through the operation of the driving component, the length of the aluminum profile can be adjusted by pulling the second aluminum profile. After the length of the aluminum profile is adjusted appropriately, the limit block is inserted into the limit slot through the operation of the driving component to limit the second aluminum profile. This not only makes the adjustment of the length of the aluminum profile more convenient, but also makes the aluminum profile more stable after the length is adjusted.

[0012] Preferably, the driving assembly includes a threaded rod rotatably connected to one side of the inner wall of the sliding cavity, the other end of the threaded rod is fixedly connected to a rotating rod, one end of the second aluminum profile is provided with a cavity, the end of the rotating rod extends away from the threaded rod into the cavity and is slidably connected to a knob, and the rotating rod is rotatably connected to the second aluminum profile, one side of the knob is fixedly connected to a limiting assembly, the outer wall of the threaded rod is threadedly connected to a threaded sleeve, the outer wall of the threaded sleeve is rotatably connected to a symmetrical connecting rod, the other end of the connecting rod is rotatably connected to the moving block, when adjusting the length of the aluminum profile, turning the knob can drive the threaded rod to rotate through the rotating rod, and the rotation of the threaded rod can move the threaded sleeve threadedly connected to it, and the threaded sleeve can drive the two moving blocks through the connecting rod when it moves. The moving blocks move in the direction of approaching at the same time. When the limit block on the moving block is out of the limit slot, the length of the aluminum profile can be adjusted by pulling the second aluminum profile. After the length of the aluminum profile is adjusted appropriately, rotating the knob in the opposite direction can make the two moving blocks move in the direction of separation at the same time. When the limit block on the moving block is inserted into the limit slot, the second aluminum profile can be limited and the aluminum profile can be used normally. The adjustment of the length of the aluminum profile with this setting is more convenient, and the knob is located inside the cavity, and the limit assembly can further limit the knob, which can effectively prevent the aluminum profile from loosening due to accidentally touching the knob and causing it to rotate, thereby making the aluminum profile more stable when used.

[0013] Preferably, the limit assembly includes a plurality of plug-in blocks fixedly connected to one side of the knob, and the plug-in blocks are equidistantly distributed on the knob in a circular array. A slot matching the plug-in block is provided on one side of the inner wall of the cavity. After turning the knob to insert the limit block on the movable block into the limit slot, the knob is pressed to insert the plug-in block on one side into the slot. This can serve as a better limit assembly for the knob, thereby effectively preventing the aluminum profile from loosening due to accidentally touching the knob and causing it to rotate during use.

[0014] Preferably, the guide block is rotatably connected to a side away from the moving block, and the balls are evenly distributed on the guide block in a linear array. When the moving block slides inside the sliding cavity, the guide block will slide inside the guide groove. The multiple balls arranged on one side of the guide block can effectively reduce the friction between the guide block and the inner wall of the guide groove, so that the moving block can slide more smoothly inside the sliding cavity.

[0015] Preferably, the end of the plug away from the knob is fixedly connected to a magnet, and the inside of the slot is fixedly connected to an iron sheet attracted to the magnet. After pressing the knob to insert the plug into the slot, the magnet at one end of the plug will be attracted to the iron sheet inside the slot, thereby fixing the plug inside the slot. This can effectively prevent the plug from falling out of the slot, thereby making the aluminum profile more stable when used.

[0016] Preferably, a slider is fixedly connected to the inner wall of the knob, and a sliding groove matching the slider is provided on the outer wall of the rotating rod. When the knob slides on the rotating rod, the slider provided on the inner wall of the knob and the sliding groove provided on the outer wall of the rotating rod can better limit and guide the knob. This not only makes the knob more stable when sliding on the rotating rod, but also effectively prevents the knob from falling off the rotating rod.

[0017] Preferably, the outer wall of the knob is provided with a rubber sleeve, and the rubber sleeve is provided with anti-slip grooves. The rubber sleeve provided on the outer wall of the knob can make people's hands more comfortable when turning the knob, and the anti-slip sleeve provided on the rubber sleeve can increase the friction between people's hands and the knob, thereby effectively preventing people's hands from slipping when turning the knob.

The guide rails 22 are provided with a plurality of guide rails 21 on the inner wall of the guide rail 3. The guide rails 22 are provided with a plurality of guide rails 21 on the inner wall of the guide rail 3. The guide rails 22 are provided with a plurality of guide rails 21 on the inner wall of the guide rail When the limit block 7 is disengaged from the limit groove 8 on the inner wall of the first aluminum profile 1, the second aluminum profile 2 can be pulled outward by the drive assembly, thereby realizing the adjustment of the length of the aluminum profile. After the length of the aluminum profile is adjusted appropriately, the two moving blocks 4 can be moved in the direction of separation at the same time by the drive assembly. When the limit block 7 on the moving block 4 is inserted into the limit groove 8, the second aluminum profile 2 can be limited and the aluminum profile can be used normally.

[0026] like Figure 2 and Figure 4As shown, the driving assembly includes a threaded rod 9 rotatably connected to one side of the inner wall of the sliding cavity 3, and the other end of the threaded rod 9 is fixedly connected to a rotating rod 10. A cavity 11 is provided at one end of the second aluminum profile 2, and the rotating rod 10 extends to the inside of the cavity 11 away from the end of the threaded rod 9 and is slidably connected to a knob 12, and the rotating rod 10 is rotatably connected to the second aluminum profile 2, and the outer wall of the knob 12 is provided with a rubber sleeve, and the rubber sleeve is provided with anti-slip grooves. The inner wall of the knob 12 is fixedly connected to a slider 19, and the outer wall of the rotating rod 10 is provided with a sliding groove 20 matching the slider 19. One side of the knob 12 is fixedly connected to a limiting assembly, and the outer wall of the threaded rod 9 is threadedly connected to a threaded sleeve 13, and the outer wall of the threaded sleeve 13 is rotatably connected to a symmetrical connecting rod 14. The other end of the connecting rod 14 is rotatably connected to the moving block 4. When adjusting the length of the aluminum profile, rotating the knob 12 can drive the threaded rod 9 to rotate through the rotating rod 10, and the thread The rotation of the rod 9 can move the threaded sleeve 13 threadedly connected thereto. When the threaded sleeve 13 moves, the two moving blocks 4 can be driven to move in the direction of approaching at the same time through the connecting rod 14. When the limit block 7 on the moving block 4 disengages from the limit groove 8, the second aluminum profile 2 can be pulled to adjust the length of the aluminum profile. After the aluminum profile length is adjusted appropriately, rotating the knob 12 in the opposite direction can make the two moving blocks 4 move in the direction of moving away at the same time. When the limit block 7 on the moving block 4 is inserted into the limit groove 8, the second aluminum profile 2 can be limited and the aluminum profile can be used normally. The adjustment of the length of the aluminum profile set in this way is more convenient, and the knob 12 is located inside the cavity 11, and the limit assembly can further limit the knob 12. This can effectively prevent the aluminum profile from loosening due to accidentally touching the knob 12 and causing it to rotate during use, thereby making the aluminum profile more stable when used.

[0027] like Figure 2 and Figure 5 As shown, the limit assembly includes a plurality of plug-ins 15 fixedly connected to one side of the knob 12, and the plug-ins 15 are equidistantly distributed on the knob 12 in a circular array. A slot 16 matching the plug-in block 15 is provided on one side of the inner wall of the cavity 11, and the end of the plug-in block 15 away from the knob 12 is fixedly connected to a magnet 17, and the inside of the slot 16 is fixedly connected to an iron sheet 18 attracted by the magnet 17. After the knob 12 is rotated to insert the limit block 7 on the movable block 4 into the limit groove 8, the knob 12 is pressed to insert the plug-in block 15 on one side into the slot 16. The magnet 17 at one end of the plug-in block 15 will be attracted by the iron sheet 18 inside the slot 16, thereby fixing the plug-in block 15 inside the slot 16. This can serve as a better limit assembly for the knob 12, thereby effectively preventing the aluminum profile from loosening due to accidentally touching the knob 12 and causing it to rotate during use.

[0028] From the above, it can be seen that the specific implementation of the present utility model is as follows:

[0029] When the aluminum profile is in use, first pull the knob 12 to disengage the plug 15 on one side from the slot 16, then turn the knob 12 to drive the threaded rod 9 to rotate through the rotating rod 10. The threaded rod 9 rotates to move the threaded sleeve 13 threadedly connected thereto. When the threaded sleeve 13 moves, the two moving blocks 4 can be driven to move toward each other at the same time through the connecting rod 14. When the limit block 7 on the moving block 4 is disengaged from the limit slot 8, the length of the aluminum profile can be adjusted by pulling the second aluminum profile 2. After the aluminum profile length is adjusted appropriately, the two moving blocks 4 can be moved away from each other at the same time by turning the knob 12 in the opposite direction. When the limit block 7 on the moving block 4 is inserted into the limit groove 8, the second aluminum profile 2 can be limited. Then the knob 12 is pressed to insert the plug 15 on one side into the slot 16. The magnet 17 at one end of the plug 15 will be attracted by the iron sheet 18 inside the slot 16, thereby fixing the plug 15 inside the slot 16. This can play a better role as a limiting component for the knob 12, thereby effectively preventing the aluminum profile from loosening due to accidentally touching the knob 12 and causing it to rotate during use, thereby making the aluminum profile more stable after the length is adjusted.
