Description

Technical Field

[0001] This utility model relates to the field of locking device technology, and in particular to a locking device for aluminum profiles. Background Technology

[0002] Aluminum profiles are widely used in fields such as automated equipment, industrial frames, and display racks due to their advantages such as lightness, aesthetics, and reconfigurability. Various workbenches, sensors, and other components are often installed on existing aluminum profiles. The current installation method is to use fasteners such as hex bolts and T-nuts to install these components on the aluminum profiles. These installation methods often require tools such as wrenches and screwdrivers, which is cumbersome. Moreover, modular assembly or rapid changeover of production lines is the future trend, which also puts forward requirements for the ease of disassembly of components. Utility Model Content

[0003] To address the shortcomings of existing components being cumbersome and inefficient to install and remove on aluminum profiles, this invention proposes a locking device for aluminum profiles that makes tightening, loosening, and installation / removal more convenient and efficient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A locking device for aluminum profiles includes a rotating assembly, mounting rods, and a slider. The rotating assembly has a non-circular cross-section transmission groove coaxially arranged at both ends. Two mounting rods are coaxially arranged on the left and right sides of the rotating assembly. The inner end of the mounting rod is adapted to the transmission groove and slidably connected in the transmission groove. The outer end of the mounting rod is provided with an external thread. The external threads of the mounting rods on the left and right sides are opposite in direction. The slider is adapted to a groove on the side of the aluminum profile. The slider is provided with a threaded hole. The outer end of the mounting rod engages with the threaded hole through the external thread.

[0005] With the above settings, the tension of the sliders on the left and right sides can be controlled by simply rotating the rotating component, which facilitates slider position adjustment and slider disassembly and assembly, thereby making it easier to replace and disassemble parts on the aluminum profile.

[0006] Furthermore, the locking device also includes a connector, which includes a connecting plate and a stabilizing sleeve. The connecting plate is provided with mounting holes, and the end of the connecting plate abuts against the aluminum profile. The stabilizing sleeve is fixedly connected to the connecting plate, and the stabilizing sleeve wraps around the mounting rod. Both ends of the rotating component abut against the stabilizing sleeve.

[0007] The above settings improve the stability of the mounting rod and facilitate the installation of components.

[0008] Furthermore, the rotating assembly includes a driving part, a driven part, a first bevel gear, a second bevel gear, and an anti-rotation mechanism. The driven part is rotatably connected to both ends of the driving part. The driven part is provided with a transmission groove on the side away from the driving part. A receiving cavity is provided inside the driving part. The first bevel gear is provided on both the left and right sides of the receiving cavity. The first bevel gear is fixedly connected to the corresponding driven part. The second bevel gear meshes between the first bevel gears. The second bevel gear is rotatably connected in the driving part. The anti-rotation mechanism is installed on the driving part and is used to brake the second bevel gear.

[0009] By setting it up as described above, you can ensure that both the left and right sliders are locked.

[0010] Furthermore, the first bevel gear is fixedly connected to the corresponding driven part through the first rotating shaft, and the driving part includes two half-shells with semi-circular grooves at both ends of the half-shells. The second bevel gear and the anti-rotation mechanism are disposed on one of the half-shells. The two half-shells are detachably connected together, and the semi-circular grooves at both ends of the two half-shells wrap around the first rotating shaft.

[0011] The above settings facilitate the assembly of the rotating components.

[0012] Furthermore, an annular groove is provided along the outer periphery of the driven part, and a retaining edge adapted to the annular groove is fixedly connected to the end of the half shell, with the retaining edge engaging in the annular groove.

[0013] With the above configuration, the driven part is stably installed on the left and right sides of the drive part.

[0014] Furthermore, the second bevel gear is rotatably connected to the half-shell via the second rotating shaft. The anti-rotation mechanism includes a friction ring and a push plate disposed on the inner and outer sides of the half-shell, and a connecting rod fixedly connected between the friction ring and the push plate. The connecting rod passes through the half-shell and is slidably connected to the half-shell. The friction ring is disposed around the second rotating shaft and faces the second bevel gear.

[0015] Furthermore, a graphite layer is provided on the wall of the semi-circular groove.

[0016] The above settings reduce the resistance between the semicircular groove and the first rotating shaft. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] Figures 1 to 4 A locking device for aluminum profiles includes a rotating assembly 3, mounting rods 4, and sliders 5. The rotating assembly 3 has a non-circular cross-section transmission groove 6 coaxially arranged at both ends. Two mounting rods 4 are arranged coaxially on the left and right sides of the rotating assembly 3. The inner end of the mounting rod 4 is adapted to the transmission groove 6 and slidably connected in the transmission groove 6. The outer end of the mounting rod 4 is provided with an external thread 9. The external threads 9 of the mounting rods 4 on the left and right sides are opposite in direction. The slider 5 is adapted to the groove 7 on the side of the aluminum profile. The slider 5 is provided with a threaded hole 8. The outer end of the mounting rod 4 is engaged with the threaded hole 8 through the external thread 9.

[0025] With the above settings, simply rotating the rotating component 3 can control the tension of the sliders 5 on the left and right sides, making it convenient to adjust the position of the sliders 5 and disassemble them, thereby facilitating the replacement and disassembly of parts on the aluminum profile.

[0026] Specifically, the locking device of this application is mainly suitable for locking components such as sensors and worktables between two parallel, stationary aluminum profiles. The aluminum profiles are rod-shaped structures with grooves 7 on their sides. The grooves 7 extend through to the end face of the aluminum profiles, and the groove openings are narrowed. This is one of the widely used aluminum profiles currently. When using the locking device of this application, an installation rod 4 is inserted into the rotating grooves at both ends of the rotating assembly 3. The cross-section of the rotating groove can be set as square or oblong. The end of the installation rod 4 can only slide axially in the rotating groove and cannot rotate. The component to be installed, such as a sensor, is installed onto the installation rod 4. The end of the installation rod 4 away from the rotating assembly 3 is threadedly connected to a slider 5. The slider 5 slides into the groove 7 from the end of the groove 7, and the installation rod 4 extends into the groove 7 from the groove opening. Initially, as Figure 4The end of the mounting rod 4 does not contact the bottom of the groove 7, that is, it does not contact the aluminum profile. The groove 7 has a narrow opening, so the slider 5 will not come out of the groove 7. The slider 5 can only slide back and forth along the groove 7, allowing the entire locking device to adjust the position of the component to be installed. After the slider 5 moves to the designated position, the rotating assembly 3 is manually rotated. The rotating assembly 3 drives the mounting rod 4 to rotate through the rotating groove. The mounting rod 4 and the slider 5 rotate relative to each other. Since the external threads 9 of the mounting rods 4 on the left and right sides are in opposite directions, when the rotating assembly 3 rotates, the mounting rods 4 on both sides move away from the rotating assembly 3, causing the end of the mounting rod 4 away from the rotating assembly 3 to move closer to the bottom of the groove 7. After tightening the rotating assembly 3, the end of the mounting rod 4 away from the rotating assembly 3 is pressed against the bottom of the groove 7. Figure 3 Under the friction between the end face of the mounting rod 4 and the bottom of the groove 7, the locking device achieves front-to-back locking. When it is necessary to adjust the front-to-back position, manually rotate the rotating assembly 3 in the opposite direction. The rotating assembly 3 drives the mounting rod 4 to rotate through the rotating groove. The mounting rod 4 and the slider 5 rotate relative to each other. The mounting rods 4 on the left and right sides move towards the rotating assembly 3 simultaneously, and the ends of the mounting rods 4 disengage from the bottom of the groove 7. Figure 4 At this point, the slider 5 can slide freely along the groove 7 to adjust the front and rear position of the locking device. The slider 5 can also slide out from the end of the groove 7 to remove the locking device.

[0027] As one implementation, the locking device also includes a connector 10, which includes a connecting plate 101 and a stabilizing sleeve 102. The connecting plate 101 is provided with a mounting hole 103. The end of the connecting plate 101 abuts against the aluminum profile 200. The stabilizing sleeve 102 is fixedly connected to the connecting plate 101. The stabilizing sleeve 102 wraps around the mounting rod 4. Both ends of the rotating component 3 abut against the stabilizing sleeve 102.

[0028] The above settings improve the stability of the mounting rod 4 and facilitate the installation of components.

[0029] Specifically, the connecting plate 101 is basically a rectangular structure with its long side extending horizontally. The wide sides on both sides are attached to the aluminum profile. The connecting plate 101 is provided with multiple mounting holes 103 to facilitate the installation of components. Several stabilizing sleeves 102 are fixedly connected to the connecting plate 101. The inner diameter of the stabilizing sleeve 102 is adapted to the outer diameter of the mounting rod 4. The stabilizing sleeve 102 wraps around the mounting rod 4 to prevent the mounting rod 4 from bending. The stabilizing sleeve 102 and the mounting rod 4 can rotate freely, allowing the rotating component 3 to rotate freely to loosen and tighten the slider 5. The connecting plate 101 is provided with multiple mounting holes 103 to facilitate the installation of the required components on the connecting plate 101. In addition, for larger components, two sets of parallel locking devices can be used for locking. Specifically, the front and rear ends of the component are locked onto the connecting plate 101 of the two sets of locking devices. After the sliders 5 of the two sets of locking devices slide into the grooves 7 and are locked, the two ends of the component are supported by the two sets of locking devices to stably lock the component between the aluminum profiles.

[0030] In another embodiment, such as Figures 5 to 6 The rotating assembly 3 includes a driving part 31, a driven part 32, a first bevel gear 33, a second bevel gear 34, and an anti-rotation mechanism 35. The driven part 32 is rotatably connected to both ends of the driving part 31. The driven part 32 is provided with a transmission groove 6 on the side away from the driving part 31. The driving part 31 is provided with a receiving cavity. The first bevel gear 33 is provided on both the left and right sides of the receiving cavity. The first bevel gear 33 is fixedly connected to the corresponding driven part 32. The second bevel gear 34 meshes between the first bevel gears 33. The second bevel gear 34 is rotatably connected in the driving part 31. The anti-rotation mechanism 35 is installed on the driving part 31 and is used to brake the second bevel gear 34.

[0031] The above settings ensure that both left and right sliders 5 are locked.

[0032] In the first embodiment, the synchronous rotation of the connecting rods 353 on the left and right sides can easily lead to one side's slider 5 locking first, while the other side's slider 5 cannot be locked. Therefore, this embodiment optimizes the rotating assembly 3. The driven part 32 is basically a cylindrical structure coaxial with the mounting rod 4, and the driving part 31 is basically a hollow cylindrical structure coaxial with the driven part 32, rotatably connected between the driven parts 32 on the left and right sides. Two first bevel gears 33 are provided, mirror-image arranged on the left and right sides of the receiving cavity, and respectively coaxially fixedly connected to the driven parts 32 on the left and right sides. The driven part 32 is inserted into the mounting rod 4 through the transmission groove 6. Initially, the sliders 5 on the left and right sides are not locked. When the driving part 31 is manually rotated, the driving part 31 drives the internal second bevel gear 34 to rotate around the axis of the driving part 31. At this time, the second bevel gear 34 plays a transmission role, and at the same time drives the mounting rods 4 on the left and right sides to rotate through the first bevel gears 33 on the left and right sides. The second bevel gear 34 basically does not rotate at this time. When one of them rotates, the second bevel gear 34 rotates. After the end of the mounting rod 4 contacts the bottom of the corresponding groove 7, that is, after one of the sliders 5 is locked, the mounting rod 4, the driven part 32, and the first bevel gear 33 corresponding to the slider 5 can no longer rotate. When the drive part 31 is manually rotated, the second bevel gear 34 will start to revolve around the axis of the drive part 31 and rotate around its own axis, continuing to drive the other bevel gear to continue locking the other slider 5. After the drive part 31 is tightened, both sliders 5 are locked. When it is necessary to unlock, the second bevel gear 34 is locked by the anti-rotation mechanism 35, and the second bevel gear 34 cannot rotate. At this time, the drive part 31 is reversed, and the drive part 31 drives the mounting rods 4 on the left and right sides to rotate synchronously through the second bevel gear 34 and the first bevel gear 33, so as to release the sliders 5 on the left and right sides.

[0033] In one implementation, the first bevel gear 33 is fixedly connected to the corresponding driven part 32 via the first rotating shaft 36. The driving part 31 includes two half-shells 311, with semi-circular grooves at both ends of the half-shells 311. The second bevel gear 34 and the anti-rotation mechanism 35 are mounted on one of the half-shells 311. The two half-shells 311 are detachably connected together, and the semi-circular grooves at both ends of the two half-shells 311 enclose the first rotating shaft 36.

[0034] The above settings facilitate the assembly of rotating component 3.

[0035] Specifically, the first bevel gear 33 is pre-installed on the driven part 32 via the first rotating shaft 36, and the second bevel gear 34 is pre-installed in one of the half-shells 311. When assembling the rotating assembly 3, the two driven parts 32 are placed opposite each other, and the two half-shells 311 are fastened together between the two driven parts 32. The semi-circular grooves of the two half-shells 311 are joined together to form a circular rotating groove that matches the first rotating shaft 36, so that the driving part 31 wraps around the first bevel gear 33 and makes the first bevel gear 33 cooperate with the second bevel gear 34. The two half-shells 311 are connected together by fasteners or welding.

[0036] As one implementation, an annular groove is provided along the outer periphery of the driven part 32, and a retaining edge 37 adapted to the annular groove is fixedly connected to the end of the half-shell 311, and the retaining edge 37 is engaged in the annular groove.

[0037] With the above configuration, the driven part 32 is stably installed on the left and right sides of the drive part 31.

[0038] The annular groove of this application is provided on the outer periphery of the driven part 32 near the driving part 31. The cross-section of the annular groove is L-shaped, and the end face of the half-shell 311 is semi-circular. A semi-circular retaining edge 37 is fixedly connected along the circumference. When assembling the rotating assembly 3, when the two half-shells 311 are fastened together, the retaining edge 37 is engaged in the annular groove. The retaining edges 37 of the two half-shells 311 are joined together to form an annular structure. On the one hand, the driving part 31 and the driven part 32 can rotate freely, and on the other hand, the end of the driving part 31 and the driven part 32 are closely fitted together and will not separate.

[0039] In one implementation, the second bevel gear 34 is rotatably connected to the half housing 311 via the second rotating shaft 38. The anti-rotation mechanism 35 includes a friction ring 351 and a push plate 352 disposed on the inner and outer sides of the half housing 311, and a connecting rod 353 fixedly connected between the friction ring 351 and the push plate 352. The connecting rod 353 passes through the half housing 311 and is slidably connected to the half housing 311. The friction ring 351 is disposed around the second rotating shaft 38 and faces the second bevel gear 34.

[0040] Specifically, when the push plate 352 is not pressed, the friction ring 351 and the second bevel gear 34 do not contact each other, such as... Figure 5 The second bevel gear 34 can rotate freely. Rotating the drive unit 31 can lock the left and right sliders 5. When it is necessary to release the sliders 5, press the push plate 352. The push plate 352 presses the friction ring 351 onto the second bevel gear 34 through the connecting rod 353. Relying on the friction between the friction ring 351 and the second bevel gear 34, the second bevel gear 34 is prevented from rotating. Reverse the drive unit 31 to release the left and right sliders 5.

[0041] As one implementation method, a graphite layer 39 is provided on the wall of the semi-circular groove.

[0042] The above settings reduce the resistance between the semicircular groove and the first rotating shaft 36.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
