Description

Technical Field

[0001] The utility model relates to the technical field of aluminum arm brackets, in particular to a stable aluminum arm bracket. Background Art

[0002] Aluminum arm brackets are usually made of aluminum alloy materials, which are widely used in various fields due to their light weight and installation characteristics.

[0003] After searching, the patent number CN220363522U discloses a stable aluminum arm bracket, which uses a combination of a positioning rod and a connecting plate to fix the sliding rod on the front end surface of the cross bracket. First, the locking rod is rotated to make its open end separate from the outer wall of the sliding rod. At this time, the sliding rod loses its restraint force. When the lifting mechanism on the four-sided racket drives the outer sliding seat to adjust the vertical position, the sliding seat is linked to the cross bracket through the cooperation of the profile mounting plate and the connecting plate, and the cross bracket is linked to the sliding rod. At this time, the position of the sleeve rod remains unchanged until the cross bracket reaches the specified height. Then, the locking rod is rotated to make its open end close to the outer wall of the sliding rod to fix the sleeve rod and the sliding rod. When the cross bracket is translated, the universal wheel at the bottom of the sleeve rod rolls synchronously, thereby providing auxiliary support for the cross bracket without hindering the movement of the cross bracket, thereby ensuring the stability of the aluminum arm bracket.

[0004] However, the length of the upper cross bracket of the above-mentioned aluminum arm bracket cannot be adjusted according to usage requirements. At the same time, when heavy goods are placed on the cross bracket, the bottom of the bracket is not effectively supported, which can easily cause the cross bracket to bend from the middle, resulting in a decrease in the overall support stability of the cross bracket.

[0033] The side walls of the cross tube 2 and the adjusting tube 6 are provided with sliding grooves, in which a sliding block 8 is slidably inserted, a connecting plate 9 is fixedly provided at the bottom of the sliding block 8, and two symmetrically arranged rotating rods 10 are rotatably provided on the surface of the connecting plate 9, a threaded rod 11 is rotatably sleeved on the rod wall of the rotating rod 10, and a support tube 12 is threadedly sleeved on the lower end of the threaded rod 11.

[0034] When the aluminum arm bracket is in use, the aluminum arm bracket can be stably moved to the designated use position through the rotation cooperation of the two walking guide wheels 21 and the cross bar 20, and then the cross tube 2 is placed on the placement frame 5 to connect the upper and lower parts of the aluminum arm bracket, and the mounting plate 26 is connected to the external equipment to fix the position of the aluminum arm bracket. In this process, the adjustment column 4 and the support column 1 can be adjusted longitudinally, and the cross tube 2 and the adjustment tube 6 can be adjusted laterally, so that the support height and width can be quickly adjusted according to the support requirements, thereby improving the versatility of the use of the aluminum arm bracket. At the same time, before the aluminum arm bracket is used, the threaded rod 11 can be driven to rotate through the rotation support of the rotating rod 10. At this time, the support tube 12 can be rotated, so that after the threaded rod 11 is rotated to a certain angle, the support tube 12 is in contact with the ground. At this time, with the auxiliary support of the two support tubes 12, the lateral support part of the aluminum arm bracket can be effectively pushed up, and the upper end of the aluminum arm bracket can be avoided from bending when the support weight is large, thereby improving the stability of the use of the aluminum arm bracket.

[0035] Example 2

[0036] Embodiment 2 is based on Embodiment 1 in order to be able to stably adjust the longitudinal height and lateral support and range of the aluminum arm bracket according to the use requirements, such as Figure 1 and Figure 4-5 As shown, the tops of the cross tube 2 and the adjusting tube 6 are each provided with a plurality of positioning threaded holes 13 arranged at intervals, and a positioning bolt 14 is threadedly passed through two longitudinally adjacent positioning threaded holes 13. The cross-sections of the support column 1 and the adjusting column 4 are both rectangular. The longitudinal adjustment mechanism includes a screw rod 27, which is rotatably disposed at the bottom of the inner wall of the support column 1 and is threadedly disposed inside the adjusting column 4. A first bevel gear 28 is fixedly sleeved at the lower end of the screw rod 27, and a driving rod 29 is rotatably passed through the lower end of the side of the support column 1.

At this time, the adjustment of the support range of the upper end of the bracket can be completed, and then the knob 31 can be turned to rotate the second bevel gear 30. Under the engagement of the first bevel gear 28 and the second bevel gear 30, the screw rod 27 rotates and drives the adjusting column 4 to move longitudinally. At this time, the support height of the aluminum arm bracket can be adjusted, thereby improving the use effect of the aluminum arm bracket.

[0038] Example 3

[0039] Embodiment 3 is based on Embodiment 1-2, in order to adjust the support position of the two support tubes 12 according to the distance between the cross tube 2 and the adjustment tube 6, as shown in FIG. Figure 1 and Figure 3 As shown, two symmetrically arranged fixing plates 15 are fixed on the upper end of the outer surface of the connecting plate 9, and worms 16 are rotatably penetrated inside the two fixing plates 15. The thread directions of the rod walls of the two worms 16 are opposite, and a rotating block 17 is fixed between the two worms 16. A worm wheel 18 is meshed with the worm 16, and the worm wheel 18 is fixedly sleeved on the outer side of the rotating rod 10. A plurality of positioning grooves 22 arranged at intervals are provided on both sides of the inner walls of the plurality of slide grooves, and two symmetrically arranged grooves are provided on the top of the sliding block 8.

[0040] After the distance between the cross tube 2 and the adjusting tube 6 is adjusted, the two positioning blocks 24 are pressed so that the positioning blocks 24 are pulled out of the positioning grooves 22 and the springs 25 are squeezed. Then, the slider 8 is moved to the middle of the two cross tubes 2 and the adjusting tube 6 by sliding between the slider 8 and the slide groove, and the positioning blocks 24 are released. Under the elastic force recovery of the spring 25, the positioning blocks 24 are inserted into the positioning grooves 22 to complete the positioning of the slider 8. Then, the rotating block 17 can be rotated to rotate the two worm gears 16. At this time, under the meshing of the worm gear 16 and the worm wheel 18, the two rotating rods 11 drive the threaded rods 11 to rotate synchronously, so that the support angle between the two support tubes 12 is adjusted. Then, the support tube 12 is rotated so that the bottom of the support tube 12 contacts the ground. At this time, the end support assembly of the aluminum arm bracket can be effectively supported under the support of multiple support tubes 12 and the threaded rods 11, thereby improving the stability of the bracket.
