Description

Technical Field

[0001] This utility model relates to the field of computer stand technology, specifically to a magnetic multi-angle locking computer stand. Background Technology

[0002] Computer stands are commonly used devices to assist in placing and adjusting the angle of computers. They are widely used in office, study and exhibition scenarios. Their core requirement is to make the angle easy to adjust and lock reliably to adapt to different usage postures.

[0003] Existing computer stand angle locking structures have several shortcomings: First, the locking operation is cumbersome, with most using knobs, bolts, or lever-type hinges, requiring both hands to rotate multiple times to fix the angle, resulting in low adjustment efficiency. Second, the locking reliability is poor; threaded or lever-type structures are prone to loosening due to vibration and wear after prolonged use, causing the computer to slide or even tip over, posing a safety hazard. Third, the structure is complex and costly; traditional hinges require multiple parts such as spring washers, nuts, and damping plates, making assembly complex, increasing production costs and the failure rate. Fourth, it is difficult to adjust quickly with one hand; in scenarios such as conference presentations and temporary repositioning, existing structures cannot achieve a quick connection between lifting the computer and locking it instantly, limiting their applicability.

[0004] Therefore, there is an urgent need for a computer stand with a simplified structure, reliable locking, and the ability to be quickly adjusted with one hand to overcome the shortcomings of existing technologies. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides a magnetic multi-angle locking computer stand.

[0006] The technical solution adopted by this utility model is: a magnetic multi-angle locking computer stand, comprising: A bracket, wherein a turntable is fixed at the bottom of the bracket, a positioning hole is provided in the middle of the bottom wall of the turntable, a concave ring is provided on the outer ring of the positioning hole, an internal toothed ring is provided on the outer side wall of the concave ring, and a first permanent magnet is provided between the concave ring and the positioning hole. A fixed base is provided, on which a positioning post is adapted to the positioning hole and a convex ring is adapted to the concave ring. An outer toothed ring is provided on the outer side wall of the convex ring to engage with the aforementioned inner toothed ring. A second permanent magnet that attracts the first permanent magnet is provided between the convex ring and the positioning post.

[0007] Furthermore, the inner and outer toothed rings have the same module of straight or trapezoidal teeth with a tooth tip angle between 50° and 80° and a tooth height of 1 to 3 mm, so that the turntable can achieve one angle lock for each tooth pitch rotation relative to the fixed base.

[0008] Furthermore, both the turntable and the fixed chassis are made of non-magnetic metal materials or high-strength engineering plastics, and the first and second permanent magnets are neodymium iron boron magnets with nickel plating or epoxy resin coating on the surface.

[0009] Furthermore, the bottom of the fixed chassis is provided with a plurality of mounting holes at intervals, and suction cups are fixedly installed in the mounting holes.

[0010] Furthermore, both the first permanent magnet and the second permanent magnet are ring structures. The first permanent magnet is embedded in the turntable and sealed and fixed with glue, while the second permanent magnet is embedded in the fixed base and sealed and fixed with glue.

[0011] Furthermore, the top of the convex ring of the fixed chassis is provided with an annular chamfer with a chamfer angle of 30°-45°, and the bottom of the concave ring is provided with a guide slope that matches the annular chamfer.

[0012] The beneficial effects of this utility model are: 1. Simplify locking operations and improve adjustment efficiency. Eliminating cumbersome structures such as knobs and bolts, it achieves locking by using permanent magnets to attract and engage with the toothed ring. During adjustment, a single hand is sufficient to disengage the toothed ring from the adjustment angle, and releasing the hand allows the magnets to automatically pull the toothed ring back into place and lock it in place, eliminating the need for both hands and significantly improving adjustment efficiency.

[0013] 2. Simplify the overall structure and reduce production and maintenance costs. The core locking structure consists only of a turntable, a fixed base, and two sets of permanent magnets, eliminating the need for spring washers, nuts, and other parts found in traditional hinges. This simplifies the assembly process, reduces production and labor costs, and lowers the failure rate due to the reduced number of parts, making subsequent maintenance more convenient.

[0014] 3. Enables quick one-handed adjustment, adapting to various scenario needs. Adapted to scenarios such as conference presentations and temporary repositioning, the bracket can be pushed with one hand to adjust the angle. After releasing the hand, the magnetic attraction and toothed ring automatically lock together, realizing a smooth one-handed operation of "adjustment-locking". This expands the applicable scenarios and enhances the practicality of dynamic use.

[0015] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This utility model provides a magnetic multi-angle locking computer stand.

[0025] In this embodiment, refer to Figure 1-4 This magnetic multi-angle locking computer stand includes: A bracket 1 is provided with a turntable 2 fixed at its bottom. A positioning hole 4 is provided in the middle of the bottom wall of the turntable 2. A concave ring 5 is provided around the outer ring of the positioning hole 4. An internal toothed ring 6 is provided on the outer side wall of the concave ring 5. A first permanent magnet 7 is provided between the concave ring and the positioning hole. A fixed base 8 is provided with a positioning post 9 that matches the positioning hole and a convex ring 10 that matches the concave ring. An outer toothed ring 11 that engages with the aforementioned inner toothed ring is provided on the outer side wall of the convex ring 10. A second permanent magnet 12 that attracts the first permanent magnet is provided between the convex ring and the positioning post.

[0026] In the above technical solution, the turntable and the bracket are fixed together, and its positioning hole and the positioning post of the fixed chassis form radial positioning to ensure that the central axis coincides during rotation. The nesting fit of the concave ring and the convex ring further improves the axial fitting accuracy. The inner toothed ring on the outside of the concave ring and the outer toothed ring on the outside of the convex ring can achieve circumferential meshing and limiting. The first permanent magnet between the concave ring and the positioning hole and the second permanent magnet between the convex ring and the positioning post generate a continuous attraction force, so that the toothed ring always maintains the fitting tendency. During adjustment, applying external force to overcome the magnetic attraction force can disengage the toothed ring. After rotating around the positioning post to the target angle, the external force is removed, and the magnetic attraction force automatically pulls the toothed ring to re-engage, completing the angle locking.

[0027] Specifically, the inner and outer toothed rings have the same module of straight or trapezoidal teeth with a tooth tip angle between 50° and 80° and a tooth height of 1 to 3 mm, so that the turntable can achieve one angle lock for each tooth pitch rotation relative to the fixed base.

[0028] In this embodiment, the same module ensures complete tooth surface fit, avoiding angular deviation caused by meshing clearance; straight teeth are easy to machine, while trapezoidal teeth improve meshing stability and adapt to different application scenarios; a tooth tip angle of 50° to 80° balances meshing tightness and adjustment smoothness—too small a tooth tip angle can easily cause jamming, while too large a tooth tip angle results in insufficient meshing depth; a tooth height of 1 to 3 mm ensures mechanical strength while reducing the requirements for the overall thickness of the turntable and chassis. The standardized tooth pitch design ensures that each tooth pitch rotation of the turntable corresponds to a fixed angle increment, forming a gear-based locking mechanism.

[0029] Specifically, both the turntable and the fixed chassis are made of non-magnetic metal materials or high-strength engineering plastics, and the first and second permanent magnets are neodymium iron boron magnets with nickel plating or epoxy resin coating on the surface.

[0030] In this embodiment, the turntable and the fixed chassis are made of non-magnetic metal materials (such as aluminum alloy and stainless steel) or high-strength engineering plastics (such as ABS and PC) to avoid the shielding or interference of magnetic materials on the magnetic field of permanent magnets and ensure stable magnetic attraction force. Neodymium iron boron magnets are the material with the highest magnetic energy product among existing permanent magnets, which can provide continuous and stable attraction force. Nickel plating or epoxy resin coating on the surface forms a protective layer to isolate air, moisture and external friction, and prevent the magnet from oxidizing, rusting or wearing.

[0031] Specifically, the bottom of the fixed chassis is provided with a plurality of mounting holes 13 at intervals, and suction cups are fixedly installed in the mounting holes.

[0032] In this embodiment, a dual fixing mechanism of "base support + suction cup adsorption" is constructed by setting mounting holes at intervals on the bottom of the fixed base and fixing suction cups there. The spaced mounting holes ensure that the suction cups are evenly distributed, ensuring that the base is under balanced force; the suction cups expel internal air by squeezing, creating an internal and external air pressure difference, generating an adsorption force on the placement surface (such as a desktop or tabletop), which, together with the weight of the base itself, achieves anti-slip fixation of the entire bracket. The detachable design of the suction cups allows for the replacement of suction cups of different diameters or materials depending on the material of the placement surface (such as glass, wood, or metal).

[0033] Specifically, both the first permanent magnet and the second permanent magnet are ring structures. The first permanent magnet is embedded in the turntable and sealed and fixed with glue, while the second permanent magnet is embedded in the fixed base and sealed and fixed with glue.

[0034] In this embodiment, the annular structure ensures a uniform magnetic field distribution of the permanent magnet, guaranteeing consistent adsorption force between the turntable and the chassis contact surface and preventing meshing deviations caused by uneven magnetic fields. The embedding method embeds the permanent magnet into the turntable and chassis, creating mechanical restraints and preventing the magnet from falling off under stress. Adhesive sealing (such as epoxy resin) creates a sealed space, isolating dust and moisture from contact with the magnet and enhancing the bond strength between the magnet and the substrate. The coaxial design of the annular structure, positioning holes, and convex rings ensures that the center of the magnetic field coincides with the center of rotation.

[0035] Specifically, the top of the convex ring of the fixed chassis is provided with an annular chamfer with a chamfer angle of 30°-45°, and the bottom of the concave ring is provided with a guide slope that matches the annular chamfer.

[0036] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
