Description

Technical Field

[0002] Aluminum alloy is the most widely used type of nonferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of industrial economy, aluminum brackets built with aluminum alloy materials have been widely used in work and life due to the excellent physical and chemical properties of aluminum alloy profiles. The erection of aluminum brackets requires the support of connectors, but the existing aluminum bracket connectors will have the following problems when used: 1. At present, when connecting aluminum profiles, it is generally necessary to use bolts to fix the two aluminum profiles on the aluminum bracket connectors respectively. This connection method requires workers to use wrenches to tighten the bolts one by one when assembling the aluminum bracket, which consumes a lot of manpower; 2. After long-term use, the existing aluminum bracket connectors and the aluminum profiles will become loose due to force and vibration, which requires workers to regularly maintain the aluminum bracket. However, during maintenance, workers generally use a wrench to tighten each bolt to ensure the stability of the aluminum bracket. This maintenance method is relatively complicated and requires a lot of manpower; 3. When the existing aluminum bracket is in use, if encountering special circumstances, the height of the aluminum profile beam part needs to be adjusted. When making the adjustment, the worker first needs to disassemble the aluminum bracket connector, thereby removing the entire aluminum profile beam, and then reinstall the aluminum profile beam at the required position using the aluminum bracket connector.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] Combination Figures 1 to 7 As shown in the figure, the aluminum bracket connector of this embodiment includes a connecting block 1, a rotating ring 2, a sliding sleeve 3 and a steel ball 4. Among them, the lower end of the connecting block 1 is provided with a first insertion end 6 that can be inserted into the side groove of the aluminum profile 5, and the upper end of the connecting block 1 is provided with a second insertion end 7 that can be inserted into the inner hole of the aluminum profile 5 along the axial direction. The rotating ring 2 is rotatably arranged on the connecting block 1. The sliding sleeve 3 is slidably arranged on the first insertion end 6 along the axial direction, that is, it can be inserted along the Figure 1 and Figure 2 As shown, the first insertion end 6 is reciprocated relative to the connection block 1 in the vertical direction, the first insertion end 6 is provided with a limiting inclined surface 8, the sliding sleeve 3 is provided with an extension opening 9 along the radial direction of the first insertion end 6, the limiting inclined surface 8 faces the extension opening 9, and the steel ball 4 is located between the sliding sleeve 3 and the first insertion end 6. The rotation of the rotating ring 2 relative to the connection block 1 can drive the sliding sleeve 3 to move in the vertical direction, and the sliding sleeve 3 can drive the steel ball 4 to extend from the extension opening 9 along the limiting inclined surface 8 and abut against the aluminum profile inclined surface 10 in the side groove of the aluminum profile 5.

[0020] In this embodiment, a sliding sleeve and a steel ball are provided, and the steel ball is moved between the limiting slope and the aluminum profile slope by utilizing the movement of the sliding sleeve relative to the connecting block. Thus, under the action of the limiting slope and the aluminum profile slope, the aluminum bracket connector can be preliminarily limited and connected to the aluminum profile, and the aluminum bracket connector can slide along the axial direction of the aluminum profile, so that when adjusting the aluminum profile beam, there is no need to remove the aluminum profile beam. Only the fixation needs to be loosened to drive the aluminum profile beam to slide axially on the vertical aluminum profile, which is convenient for rapid adjustment after installation.

[0021] Combination Figure 5 and Figure 7 As shown, in the aluminum bracket connector of this embodiment, when the sliding sleeve 3 moves toward the direction close to the limiting inclined surface 8 to the maximum distance position, that is, along Figure 7 As shown, when it moves downward to abut against the first insertion end 6 in the connecting block 1 , the distance between the limiting inclined surface 8 and the aluminum profile inclined surface 10 is equal to the diameter of the steel ball 4 .

[0022] At this time, the steel ball can be confined between the sliding sleeve and the connecting block so that it can extend out of the sliding sleeve to the largest possible size, and the forces exerted on the steel ball by the limiting slope and the aluminum profile slope are directed to the center of the ball, so that the steel ball maintains a stable position, thereby improving the stability and firmness of the connection between the aluminum profile and the connecting block.

[0023] Combination Figure 2 and Figure 6 As shown, in the aluminum bracket connector of this embodiment, the rotating ring 2 is provided with a first magnet 11 and a second magnet 12, and the sliding sleeve 3 is provided with a third magnet 13 and a fourth magnet 14. When the rotating ring 2 rotates relative to the connecting block 1 until the first magnet 11 is aligned with the third magnet 13 and the second magnet 12 is aligned with the fourth magnet 14, the sliding sleeve 3 can be driven to move in a direction away from the limiting inclined plane 8, that is, the mutually aligned magnets generate a force of mutual attraction, thereby attracting the sliding sleeve 3 to move in a direction close to the rotating ring 2 and away from the limiting inclined plane 8. Conversely, when the rotating ring 2 rotates relative to the connecting block 1 until the first magnet 11 is aligned with the fourth magnet 14 and the second magnet 12 is aligned with the third magnet 13, the sliding sleeve 3 can be driven to move in a direction close to the limiting inclined plane 8, that is, the mutually aligned magnets generate a force of mutual repulsion, thereby pushing the sliding sleeve 3 to move in a direction away from the rotating ring 2 and close to the limiting inclined plane 8.

[0024] At this time, by setting a magnet between the rotating ring and the sliding sleeve, and utilizing the rotation of the rotating ring relative to the connecting block, the interaction force generated between the magnets can be utilized to control the movement of the sliding sleeve relative to the first insertion end, thereby controlling the extension or retraction of the steel ball, thereby realizing the connection and separation operations between the connecting block and the aluminum profile.

[0025] Combination Figure 2 and Figure 5 As shown, in the aluminum bracket connector of this embodiment, a spring 15 is further provided between the sliding sleeve 3 and the connecting block 1. The spring 15 can drive the sliding sleeve 3 to move toward the direction close to the limiting inclined surface 8, and the action force generated between the first magnet 11, the second magnet 12, the third magnet 13 and the fourth magnet 14 can drive the sliding sleeve 3 to overcome the spring 15 and move away from the limiting inclined surface 8.

[0026] At this time, by setting a spring between the sliding sleeve and the connecting block, the force generated by the spring can be used to apply a force to the sliding sleeve in the direction of the limiting inclined surface, thereby generating a greater force on the steel ball to make it press against the limiting inclined surface, further improving the connection stability and firmness between the connecting block and the aluminum profile.

[0027] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in the aluminum bracket connector of this embodiment, a transmission rod 16 is further provided, a positioning groove 17 is provided on the rotating ring 2, and a positioning rod 18 corresponding to the positioning groove 17 is provided on the outer circumferential surface of the transmission rod 16, and the transmission rod 16 is slidably arranged on the connecting block 1 along the axial direction of the first insertion end 6, that is, along Figure 2 The vertical transmission rod 16 can reciprocate relative to the connecting block 1 but cannot rotate relative to it. Figure 1 The swivel ring 2 extends into the positioning groove 17 in the downward direction as shown, so as to limit the relative rotation between the rotating ring 2 and the connecting block 1.

[0028] At this time, by means of the relative rotation between the rotating ring and the connecting block, the connecting block and the aluminum profile are fixedly connected, and then the relative rotation between the rotating ring and the connecting block can be limited by driving the transmission rod downward to make the positioning rod extend into the positioning groove, so that the connecting block and the aluminum profile remain in a connected state.

[0029] Combination Figures 1 to 6 As shown, in the aluminum bracket connector of this embodiment, a fixing nail 19 is further provided at the lower end of the transmission rod 16. The fixing nail 19 can extend out of the connection block 1 along with the movement of the transmission rod 16 and abut against the side of the aluminum profile 5. In this way, the cooperation between the fixing nail and the steel ball can be utilized to further improve the firmness of the connection between the connection block and the aluminum profile.

[0030] Among them, combined Figure 1 and Figure 3 As shown, a plurality of mutually spaced fixing nails 19 are provided at the end of the transmission rod 16 of the present embodiment, thereby increasing the contact area between the transmission rod and the aluminum profile and improving the firmness of the connection between the connecting block and the aluminum profile.

[0031] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in the aluminum profile connector of this embodiment, a transmission groove 20 is provided at the upper end of the transmission rod 16, and a connecting nail 21 is provided on the second insertion end 7. The transmission groove 20 is an inclined groove, and the connecting nail 21 is slidably arranged along the radial direction of the second insertion end 7. When the transmission rod 16 moves downward relative to the connection block 1, the transmission groove 20 can move downward with the transmission rod 16, and the connecting nail 21 is driven to extend out of the second insertion end 7 and abut against the inner hole of the aluminum profile 5 through the inclined groove bottom 29 in the transmission groove 20.

[0032] At this time, by setting a transmission groove on the transmission rod and setting a connecting nail at the second insertion end, the connection between the connecting block and the aluminum profile can be reinforced when the transmission rod is used to limit the relative rotation of the connecting block and the rotating ring, thereby completing the connection between the two sections of aluminum profile and the aluminum profile connecting piece at the same time, realizing a quick and convenient connection of the two sections of aluminum profile, and there is no need to use a wrench to tighten the screws, saving manpower.

[0033] Combination Figure 1 As shown, the transmission rod 16 of the present embodiment is provided with a plurality of transmission grooves 20 distributed along its axial direction, and a plurality of connecting nails 21 are arranged axially at the second insertion end 7, so that the plurality of connecting nails 21 can be extended to form abutment with the inner hole of the aluminum profile 5, thereby increasing the connection area between the second insertion end 7 in the connecting block 1 and the aluminum profile 5, and improving the connection stability between the two.

[0034] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in the aluminum bracket connector of this embodiment, the transmission rod 16 is further provided with a section of driving gear shaft 22 along its axial direction, and the connecting block 1 is provided with a control gear 23. The control gear 23 is rotatably connected to the connecting block 1 and meshed with the driving gear shaft 22, and the control gear 23 can drive the transmission rod 16 to reciprocate axially through the driving gear shaft 22.

[0035] At this time, by controlling the reciprocating rotation of the control gear, the reciprocating movement of the transmission rod can be controlled by the driving gear shaft, thereby controlling the connection and removal of the aluminum bracket connector and the aluminum profile.

[0036] Combination Figure 1 As shown, in the aluminum bracket connector of this embodiment, a handle 24 is further provided on the control gear 23, and the handle 24 can be used to drive the control gear 23 to reciprocate, thereby improving the convenience of operation.

[0037] Combination Figure 1 and Figure 5As shown, in the aluminum bracket connector of this embodiment, a ratchet 25 is further provided. The ratchet 25 is rotatably connected to the connecting block 1 through a torsion spring 26, and the ratchet 25 is meshedly connected with the driving gear shaft 22 to limit the unidirectional movement of the driving gear shaft 22, that is, when the ratchet 25 is meshedly connected with the driving gear shaft 22, it can limit the transmission rod 16 from moving in a direction away from the first insertion end 6, that is, prevent the transmission rod 16 from moving in a direction away from the first insertion end 6. Figure 1 Move upward as shown.

[0038] In this embodiment, a pawl is provided to limit the unidirectional movement of the driving gear shaft, so that the transmission rod can move in a direction close to the first insertion end but cannot move in a direction away from the first insertion end, thereby avoiding accidental relative movement between the aluminum profile and the aluminum bracket connecting piece, causing the transmission rod to move upward, and further avoiding accidental loosening between the aluminum profile and the aluminum bracket connecting piece, further improving the connection firmness and stability between the aluminum profile and the aluminum bracket connecting piece.

[0039] At the same time, combined Figure 1 and Figure 5 As shown, in the aluminum bracket connector of this embodiment, a button 27 is also provided. The button 27 is slidably arranged on the connecting block 1, and the button 27 can be driven to abut against the pawl 25 to drive the pawl 25 to overcome the torsion spring 26 and rotate to disengage from the meshing connection with the driving gear shaft 22.

[0040] At this time, by setting a button on the connecting block, the button can be driven to control the pawl to disengage from the drive gear shaft, thereby releasing the unidirectional movement restriction on the transmission rod and allowing the transmission rod to move away from the first insertion end, thereby allowing the aluminum profile connector and the aluminum profile to be dismantled.

[0041] In addition, combined Figure 2 and Figure 6 As shown, in the aluminum bracket connector of this embodiment, two slide rails 28 are further provided on the connection block 1, and the two slide rails 28 are respectively arranged on both sides of the second insertion end 7 along the axial direction of the second insertion end 7. At this time, when the second insertion end 7 is inserted into the inner hole of the aluminum profile 5, the two slide rails 28 can be inserted into the grooves on the side of the aluminum profile 5 to assist in fixing the aluminum profile 5, thereby improving the connection firmness and stability between the second insertion end 7 and the aluminum profile 5 in the connection block 1.

[0042] Combination Figures 1 to 7 As shown, the connection operation of the aluminum profile using the aluminum bracket connector of this embodiment is as follows: When the aluminum bracket connector of this embodiment is used to vertically connect two sections of aluminum profiles, the second insertion end 7 of the connecting block 1 is axially inserted into the inner hole of one of the aluminum profiles 5, and the two slide rails 28 are inserted into the grooves on the side of the aluminum profile 5, as shown in FIG. Figure 6As shown, the first insertion end 6 of the connecting block 1 is inserted into the side groove of another aluminum profile 5, and the bottom surface of the connecting block 1 is fitted with the side surface of the aluminum profile 5, that is, Figure 5 At this time, the first magnet 11 is aligned with the third magnet 13, and the second magnet 12 is aligned with the fourth magnet 14. The magnets are attracted to each other, so that the sleeve 3 overcomes the force of the spring 15 and moves upward. Figure 1 The position shown is far away from the limiting slope 8, so that the steel ball 4 is far away from the limiting slope 8 and is located inside the sliding sleeve 3, thereby ensuring that the first insertion end 6 can be smoothly inserted into the groove on the side of the aluminum profile 5. The driving rotating ring 2 is rotated relative to the connecting block 1, and the rotating ring 2 rotates around the driving gear shaft 22 on the transmission rod 16 with the control gear 23 and the ratchet 25 until the first magnet 11 is aligned with the fourth magnet 14, and the second magnet 12 is aligned with the third magnet 13, and the magnets are transformed into mutually repelling forces, and under the action of the spring 15, the sliding sleeve 3 moves in the direction close to the limiting slope 8, so that the steel ball 4 moves along Figure 1 As shown in the downward direction, since the distance between the limiting inclined plane 8 and the aluminum profile inclined plane 10 is equal to the diameter of the steel ball 4, the steel ball 4 moves downward and slides along the gap between the limiting inclined plane 8 and the aluminum profile inclined plane 10, and the steel ball 4 extends out of the sliding sleeve 3 under the action of the limiting inclined plane 8. When the sliding sleeve 3 moves downward to the bottom and forms a fit with the first insertion end 6, that is, Figure 7 In the position shown, the preliminary connection of the aluminum profile is completed and it is in a translation state. At this time, if the aluminum profile 5 and the first insertion end 6 are pulled in the separation direction, since the line between the contact point between the aluminum profile inclined surface 10 and the steel ball 4 and the contact point between the limiting inclined surface 8 and the steel ball 4 passes through the center of the steel ball 4, the force of the limiting inclined surface 8 pushing the steel ball 4 is directed to the center of the ball, and the force of the aluminum profile inclined surface 10 pushing the steel ball 4 is also directed to the center of the ball, that is, the two forces are in opposite directions, and since the limiting inclined surface 8 and the aluminum profile inclined surface 10 both have a certain inclination angle, the steel ball 4 cannot move, and the first insertion end 6 cannot be pulled out of the aluminum profile 5, but the connection block 1 can be pushed along the axial direction of the aluminum profile 5 to move, thereby adjusting the installation position of the connection block 1.

[0043] After the installation position adjustment of the aluminum bracket connector of this embodiment is completed, the control gear 23 is driven to rotate by the handle 24, and the transmission rod 16 is moved to the right by the driving gear shaft 22. Figure 1As shown in the downward movement, on the one hand, the rotating ring 2 aligns the positioning groove 17 with the positioning rod 18 through the above rotation, so that the downward movement of the transmission rod 16 inserts the positioning rod 18 into the positioning groove 17 to limit the relative rotation between the rotating ring 2 and the connecting block 1, and makes the fixing nail 19 at the lower end of the transmission rod 16 move downward and abut against the side of the aluminum profile 5, completing the fixed connection between the aluminum profile 5 and the connecting block 1. On the other hand, the downward movement of the transmission rod 16 causes the transmission groove 20 to push the connecting nail 21 to extend out of the second insertion end 7 and abut against the inner wall of the inner hole of the aluminum profile 5, completing the fixed connection between the aluminum profile 5 and the second insertion end 7 in the connecting block 1. When the handle 24 is rotated to be flush with the side of the aluminum profile 5, that is, Figure 5 In the position shown, the aluminum bracket connector of this embodiment enters a fixed state and completes the fixed connection with the two sections of aluminum profiles.

[0044] When the aluminum bracket connector of this embodiment is loosened after being connected to the aluminum profile for a long time, the push handle 24 is further rotated, that is, Figure 5 Pushing the handle 24 in the left direction as shown in the figure, the transmission rod 16 is continuously driven to the right through the control gear 23, the drive gear shaft 22 and the ratchet 25. Figure 5 The downward movement shown in the figure allows the fixing nail 19 to continue to extend and abut against the side of the aluminum profile 5, thereby improving the connection firmness between the connecting block 1 and the aluminum profile 5, and allows the connecting nail 21 to continue to extend and abut against the inner wall of the inner hole of the aluminum profile 5, thereby improving the connection firmness between the connecting block 1 and the aluminum profile 5.

[0045] When the position of the aluminum profile needs to be adjusted, the button 27 is pushed to drive the pawl 25 to overcome the torsion spring 26 and rotate to disengage the meshing connection with the drive gear shaft 22, and the handle 24 is rotated in the opposite direction, that is, to Figure 5 Turning the handle 24 in the right direction as shown drives the transmission rod 16 to the right through the control gear 23 and the drive gear shaft 22. Figure 5 The upward movement shown drives the fixing nail 19 to disengage from the side of the aluminum profile 5, so that the connecting block 1 can translate relative to the aluminum profile 5 again. At this time, under the limiting action of the steel ball 4, the connecting block 1 can slide along the axial direction of the aluminum profile 5, so that the position of the aluminum profile can be adjusted.

[0046] When it is necessary to dismantle the connection between the aluminum bracket connector of this embodiment and the aluminum profile, firstly, the above operation is performed to enable the connecting block 1 to translate relative to the aluminum profile 5, and the positioning rod 18 is moved upward with the transmission rod 16 to disengage from the positioning groove 17, thereby releasing the relative rotation restriction between the rotating ring 2 and the connecting block 1, and the rotating ring 2 is rotated to align the first magnet 11 with the third magnet 13, and the second magnet 12 with the fourth magnet 14. Under the mutual attraction between the relative magnets, the sliding sleeve 3 overcomes the force of the spring 15 and moves upward, and the positioning rod 18 is overlapped with the upper end surface of the rotating ring 2 after rotation to keep the sliding sleeve 3 in the position after the upward movement, that is, Figure 1 In the position state shown, the upward movement of the sliding sleeve 3 drives the steel ball 4 to move upward and slide along the gap between the limiting inclined surface 8 and the aluminum profile inclined surface 10, moving the steel ball 4 into the sliding sleeve 3, releasing the connection between the connecting block 1 and the aluminum profile 5. At the same time, the upward movement of the transmission rod 16 causes the transmission groove 20 to lose the force on the connecting nail 21, releasing the connection between the connecting block 1 and the aluminum profile 5, and the connecting block 1 can be pulled out from the aluminum profile 5 to complete the removal operation.
