Description

Technical Field

[0001] This utility model belongs to the field of display bracket technology, and specifically relates to a damping positioning shaft seat, and more particularly to a solution that allows the vertical axis of the bracket to remain stable in its initial state as the fixed object tilts. Background Technology

[0002] The vertical positioning axis of a monitor stand is generally used when it is perpendicular to a fixed object such as a desktop, and the desktop or other fixed object remains stable, so there is little need to consider whether the positioning axis will change direction due to the load. However, in some special situations, such as when placed on a tilted fixed object or in gaming applications where the desktop moves with the monitor screen, the positioning axis must be locked; otherwise, it will rotate in the direction of the load. While locking the positioning axis to maintain its orientation is the simplest structure, its biggest drawback is the difficulty in adjustment.

[0003] The object of this invention is how to incorporate the concept of a damping axis into the technical solution for positioning a vertical axis. Summary of the Invention

[0004] The purpose of this invention is to design a damping positioning shaft seat that can resist the load and remain stable when the vertical shaft is tilted.

[0005] The technical solution of this utility model is implemented as follows: a damping positioning shaft seat includes a seat body that can be fixed on a fixed object and a vertical shaft that stands on the horizontal surface of the seat body; characterized in that: the vertical shaft passes through a shaft hole on the horizontal surface of the seat body, and the inner end is locked with a wheel, which abuts against an adjustable damping mechanism provided on one side of the seat body, and the adjustable damping mechanism maintains the balance with the load torque of the vertical shaft.

[0006] The base has a shaft cylinder section integrally formed outside the shaft hole. A bearing is provided at the upper and lower ends of the shaft cylinder section, and the vertical shaft can be rotatably positioned through the bearings.

[0007] The vertical shaft is provided with a rotational travel limit, which includes a travel groove, a self-locking switch and a travel rod located around the wheel; the self-locking switch and the travel rod are located on the inner surface of the seat, and the travel rod is installed in the slide groove of the seat. The action of the self-locking switch is linked to the travel rod extending into or retracting from the travel groove.

[0008] A flange is also provided on the vertical shaft, which abuts against the top of the shaft section, and a gasket is provided between the two.

[0009] As a preferred embodiment, the wheel is a wear-resistant disc, and the corresponding adjustable damping mechanism is a caliper disposed outside the wheel. The adjustable bolt for driving the caliper's clamping force is rotatably positioned on the horizontal surface of the base.

[0010] As a preferred embodiment, the wheel is a main gear, and the corresponding adjustable damping mechanism includes a driven gear meshing with the main gear and a friction disc clamped on the end face of the driven gear. An adjustable bolt for driving the clamping force of the friction disc passes through the driven gear and the friction disc and is rotatably positioned on the horizontal surface of the base.

[0011] Furthermore, a disc-shaped spring is provided at the center between the contact surfaces of the gear and the friction disc, and nested conical rings are provided around the periphery, with the tightness of the fit adjusted by an adjustable bolt.

[0012] Furthermore, there are two friction discs: an upper friction disc that abuts against the inner wall of the horizontal surface of the seat and a lower friction disc that can be driven by an adjustable bolt; a hard liner is also provided on the bottom surface of the lower friction disc, which is driven by the nut of the adjustable bolt to press against the lower friction disc.

[0013] Furthermore, the vertical shaft is equipped with a rotating sound mechanism, which includes a corrugated wheel assembly connected to one end face of a main gear or a driven gear, a self-locking switch, and a toggle lever. The self-locking switch and the toggle lever are disposed on the inner surface of the seat body, and the toggle lever is installed in the slide groove of the seat body. The action of the self-locking switch is linked to the toggle lever abutting against the surface of the corrugated wheel assembly, and the rotation of the corrugated wheel assembly moves the toggle lever to produce a sound.

[0014] This invention employs damped positioning for the vertical axis, maintaining the convenience of rotational adjustment while ensuring the stability of the fixed axis. It features a unique overall design, reasonable structure, and adjustable damping range, meeting the needs of different loads and tilt angle changes, and maintaining stable support within the maximum design tilt angle.

[0030] Reference Figures 1 to 3 The damping positioning shaft seat includes a seat body 1 that can be fixed to a fixed object and a vertical shaft 2 that stands upright on the horizontal surface of the seat body. There are two ways to fix the seat body 1 to the fixed object: one is to place it directly on the horizontal platform or other objects by means of counterweight; the other is to clamp it to the edge of the platform by means of clamps or to lock it by means of bolts passing through it. The illustration shows the solution using clamps. On one side of the seat body 1, usually the rear side, there is a clamping plate 15 with adjustable spacing. The clamping plate 15 and the seat body are used to clamp it to the edge of the platform, making the seat body 1 stable. The supported object, such as the bracket, is directly locked to the upper end of the vertical shaft 2, and the vertical shaft 2 can be used to adjust the orientation to meet the viewing needs of sitting in different positions.

[0031] To achieve a damping effect where the vertical axis 2 is both adjustable and positionable, the following structure is adopted:

[0032] A shaft hole 11 is provided on the horizontal surface of the base. A shaft sleeve section 12 is integrally formed outside the shaft hole. A bearing 4 is provided at the upper and lower ends of the shaft sleeve section 12. The vertical shaft 2 can be rotatably positioned through the bearings 4. The double bearing design ensures that the vertical shaft 2 has good torsional resistance.

[0033] The vertical shaft 2 passes through the inner end of the seat and is locked to a wheel 21. The wheel 21 abuts against an adjustable damping mechanism 3 located on one side of the seat 1. The adjustable damping mechanism 3 maintains the balance with the load torque of the vertical shaft 2.

[0034] Reference Figures 4 to 6To prevent the vertical shaft 2 from rotating and tangling with the cable, a rotational travel limit is provided on the vertical shaft 2. This travel limit includes a travel groove 22 located around the wheel 21, a self-locking switch 5, and a travel rod 51. The self-locking switch 5 and the travel rod 51 are located on the inner surface of the base 1. The travel rod 51 is installed in the slide groove 13 of the base. The action of the self-locking switch 5 triggers the travel rod 51 to extend into or retract from the travel groove 22. That is, the self-locking switch 5 drives the travel rod 51 to achieve a feeding action, entering the travel groove 22 to achieve the limit and enter the working state, avoiding excessive rotation by human intervention; after release, it facilitates disassembly and assembly operations.

[0035] Furthermore, a flange 23 is also provided on the vertical shaft 2, which abuts against the top of the shaft cylinder section 12, and a gasket 24 is also provided between the two to provide a gravity transmission path, such as... Figure 2 .

[0036] As a preferred implementation: the wheel 21 is a master gear, and the corresponding adjustable damping mechanism 3 includes a driven gear 31 meshing with the master gear and a friction disc 32 clamped on the end face of the driven gear 31. An adjustable bolt 33, which drives the clamping force of the friction disc 32, passes through the driven gear 31 and the friction disc 32 and is rotatably positioned on the horizontal plane of the base 1. The adjustable bolt 33 plays a dual role here: firstly, its rotation relative to the base is used to adjust the tightness of the friction disc 32 and control the friction force; secondly, it provides a positioning shaft function for the driven gear 31 and the friction disc 32.

[0037] Between the contact surfaces of gear 31 and friction disc 32, a disc-shaped spring 34 is positioned at the center, surrounded by nested conical rings 35, and the tightness is adjusted by an adjustable bolt 33. The design of the conical rings 35 increases the friction area and improves the friction force, while the disc-shaped spring 34 has the opposite effect; when adjusted in the loosening direction, it is easy to push the two apart.

[0038] More specifically, there are two friction discs 32: an upper friction disc 321 that abuts against the inner wall of the horizontal plane of the base 1, and a lower friction disc 322 that can be driven by an adjustable bolt 33. A rigid liner 36 is also provided on the bottom surface of the lower friction disc 322. This rigid liner 36 is driven by a nut 331 matching the adjustable bolt 33 to press against the lower friction disc 32. The rigid liner 36 ensures that the force is evenly transmitted to the periphery of the lower friction disc 322. A base plate 14 is also provided at the bottom of the base 1 to enclose the components and to provide positioning for the friction discs 32, preventing them from shifting during adjustment. For example, pin holes 141 are provided on the inner surface of the base 1 and the base plate 14, and pins 323 are provided on the back of each friction disc 32. When assembled, the pins 323 are inserted into the pin holes 141 for positioning. Similarly, the pins 323 also pass through the rigid liner 36 and are positioned together with the nut 331.

[0039] Furthermore, to achieve rotation sensing of the vertical shaft 2, a rotation sound mechanism 6 is provided on the vertical shaft 2. This rotation sound mechanism 6 includes a corrugated wheel assembly 61 integrally formed with one end face of the main gear or driven gear 31, a self-locking switch 5, and a toggle lever 62. The self-locking switch 5 and the toggle lever 62 are disposed on the inner surface of the base 1. The toggle lever 62 is installed in the slide groove 13 of the base. The action of the self-locking switch 5 triggers the toggle lever 62 to abut against the surface of the corrugated wheel assembly 61, causing the corrugated wheel assembly to rotate and move the toggle lever 62 to produce a sound. It should be noted that the toggle lever 62 has two options: one is a spring plate, which rebounds when moved and produces a sound; the other is an elastic telescopic rod, which retracts when moved and rebounds to strike the corrugated wheel assembly 61 to produce a sound.

[0040] As a simplified implementation scheme: the wheel 21 is a wear-resistant disc, and the corresponding adjustable damping mechanism 3 is a caliper located outside the wheel 21. The adjustable bolt 33, which drives the caliper's clamping force, is rotatably positioned on the horizontal surface of the base 1. Here, the caliper is a disc brake caliper, replacing the hydraulic drive of the brake pads with the drive of the adjusting bolt 33. The rotational stroke limit and rotational sound mechanism are also applicable.

[0041] The aforementioned self-locking switch 5, also known as a bistable mechanical switch, is a common small component in the mechanical and electronic fields. Its working principle involves switching and locking the state with a single press. Common examples include the push-pull switches in ballpoint pens, the push-pull switches in SD card slots, and the power switches used in various electrical appliances. Figure 5 and Figure 6 The self-locking switch 5 is an eccentric heart-shaped groove, and the swing pin 52 can be swing-fixed on the base 1 and the base plate 14 respectively to control the self-locking switch 5 to switch the feed state.
