Description

Technical Field

[0001] The utility model relates to the technical field of aluminum brackets, in particular to an aluminum bracket operating mechanism with adjustable length. Background Art

[0002] Aluminum profile racks are also called assembly line aluminum profile racks and aluminum profile frames. They refer to equipment racks, brackets, load-bearing skeletons, and wire frames made of industrial aluminum profiles. They are one of the extended products of profile applications and can be used in multiple industries, among which the mobile phone bracket industry is more common.

[0003] Referring to Chinese patent authorization announcement number CN220325651U, a mobile phone holder includes: a holder base, the side edge of the holder base is provided with a clamping part for clamping the mobile phone; a holder plate, the upper side end of the holder plate is hinged to the upper side of the holder base, and can fit with the holder base after rotation, in a flat state; or form an angle with the holder base, in a holder state; a limit plate, one end of the limit plate is hinged to the free end of the holder plate, and the other end is connected to the holder base in a sliding limit position. When the holder plate is opened, the limit plate slides along the base, and the limit plate is connected between the holder base and the holder plate, and has a limit support function. The mobile phone holder described in this utility model has stable support, light structure, and durability;

[0004] By referring to the above comparison, it can be seen that in the prior art, since the aluminum bracket operating mechanism is often used to support mobile phones, and the mobile phone is generally clamped and fixed by the clamping structure on the bracket, but during the clamping process, the mobile phone is often clamped and fixed by the clamping plate driven by the rebound force of the spring. This clamping method generally requires manual pulling of the clamping plate and compression of the spring, and then the clamping plate is driven by the elastic force of the spring to clamp the mobile phone. The operation process is relatively cumbersome, and the length of the aluminum bracket operating mechanism is not convenient to adjust, so it is difficult to conveniently adjust the operating height of the mobile phone, which easily affects the user experience comfort.

[0005] Therefore, how to design an aluminum bracket operating mechanism with adjustable length has become a problem that we currently need to solve. Utility Model Content

The hollow mounting plate 1 is connected with a lower return spring 10, and L-shaped clamping plates 7 are provided on both sides of the left and right sides of the hollow mounting plate 1. The front end of the inner side of the L-shaped clamping plate 7 is fixed with a side limit block 15, and the rear end of the inner side of the L-shaped clamping plate 7 is fixed with a side movable rod 11. The side movable rods 11 are slidably penetrated into the hollow mounting plate 1, and the ends of the side movable rods 11 are fixed with side pressure blocks 12.

When the threaded adjustment rod 19 rotates, it will drive the internal threaded sleeve 16 and the support shaft 4 to move up and down. At the same time, the support shaft 4 will stretch or compress the telescopic rod 17, thereby ensuring the stability of the internal threaded sleeve 16 and the support shaft 4 moving up and down. When the support shaft 4 moves up and down, it will drive the support plate 24 and the hollow mounting plate 1 to move up and down together. Therefore, the height of the bracket can be easily adjusted, which is conducive to adjusting the bracket to a comfortable height for the user to operate. In addition, by rotating the damping shaft 18, the use position of the bracket after rotation can be easily adjusted.

The block 30 will compress the spring return rod 28, so that the block 30 can be easily moved out of the slot 29, and then the support shaft 4 is moved out of the slot 26, which is convenient for disassembling the hollow mounting plate 1 for separate use or maintenance, and the support shaft 4 is inserted into the slot 26. At this time, the support shaft 4 pushes the block 30 into the contraction slot 27 along the inclined surface of the block 30, and the block 30 will compress the spring return rod 28 until the block 30 is aligned with the notch of the slot 29. The elastic force of the spring return rod 28 will drive the block 30 to automatically fit into the slot 29, thereby facilitating the installation of the hollow mounting plate 1 on the bracket for use.

[0042] The working process of the utility model is as follows: put the mobile phone on the L-shaped support plate 5 from top to bottom, the gravity of the mobile phone will drive the L-shaped support plate 5 to move downward, in this process, the L-shaped support plate 5 will drive the lower movable rod 8, the lower pressure block 9 and the linkage rod 14 to move downward, the lower pressure block 9 will compress the lower return spring 10, and at the same time the lower movable rod 8 will drive the linkage rod 14 to rotate, so the linkage rod 14 will pull the side movable rod 11, the side pressure block 12 and the L-shaped clamping plate 7 inward, the side pressure block 12 will stretch the side return spring 13, and the L-shaped The clamping plate 7 will approach the side of the mobile phone until the two L-shaped clamping plates 7 clamp the two sides of the mobile phone, turn the knob 22 and drive the main bevel gear 20, the auxiliary bevel gear 21 and the threaded adjustment rod 19 to rotate, and when the threaded adjustment rod 19 rotates, it will drive the internal threaded sleeve 16 and the support shaft 4 to move up and down, and at the same time, the support shaft 4 will stretch or compress the telescopic rod 17, and when the support shaft 4 moves up and down, it will drive the support plate 24 and the hollow mounting plate 1 to move up and down together, so the use height of the bracket can be conveniently adjusted.
