Description

Technical Field

[0001] This invention relates to the field of brackets, specifically a telescopic floor bracket. Background Technology

[0002] With the widespread use of electronic devices such as tablets, mobile phones, and monitors, the demand for stands that can flexibly support these devices is increasing. Floor stands, due to their ability to be moved and placed freely without being fixed to a wall or desktop, are widely used in homes, offices, and commercial displays. However, existing floor stands still have shortcomings in height adjustment, arm extension, and suspension stability.

[0003] Traditional floor stands typically use a sleeve-type structure, with height locking via knobs or set screws. This adjustment method is cumbersome, requiring both hands, and the locking force is difficult to control, easily leading to slippage or difficulty locking. Furthermore, to meet different height requirements, multiple adjustment levels are often needed, but the adjustment process is not smooth, resulting in a poor user experience.

[0004] Furthermore, existing floor mounts mostly use gas springs or ordinary coil springs for support on their crossarms. Gas springs are expensive and pose a risk of air leakage; ordinary coil springs are difficult to provide constant support force throughout the entire stroke, resulting in uneven feel of the crossarm during raising and lowering, making it difficult to achieve stable hovering at any position.

[0005] Therefore, we propose a telescopic floor support to solve the above problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a telescopic floor support.

[0007] The present invention provides a telescopic floor stand, including a base, a fixed column fixed to the top of the base, an extension column embedded in the top of the fixed column, a height locking mechanism cooperating with the fixed column at the bottom of the extension column, a slide rail assembly slidably connected inside the extension column, a constant force spiral spring installed inside the slide rail assembly, the extension end of the constant force spiral spring being fixedly connected to the top of the extension column, and a cross arm installed on the slide rail assembly.

[0008] Preferably, a dual-axis torque hinge is installed at the end of the cross arm, and a mounting plate is fixed at the output end of the dual-axis torque hinge.

[0009] Preferably, the base has a mounting hole at the top for accommodating the fixed column, the fixed column is hollow, a connecting plate is installed on the inner side of the bottom end of the fixed column, and a sealing plate for sealing the bottom of the mounting hole is fixedly connected to the bottom of the base by screws, the sealing plate being fixedly connected to the connecting plate by screws.

[0010] Preferably, the side wall of the fixed column is provided with several locking holes, the height locking mechanism includes a V-shaped spring and a limiting post, the extension column is hollow, a bottom plug is embedded and fixed at the bottom end of the extension column, a V-shaped spring is provided on the inner side of the extension column, a limiting post is fixed at the bend of the V-shaped spring, the limiting post protrudes through the side wall of the extension column and cooperates with the locking holes, and both ends of the V-shaped spring are in contact with the inner wall of the extension column.

[0011] Preferably, the slide rail assembly includes a U-shaped sheet metal part, with several sliders fixed on both sides of the U-shaped sheet metal part, and the sliders are slidably connected to the extension column. Several mounting seats are installed on the inner side of the U-shaped sheet metal part, and the mounting seats are provided with arc-shaped grooves. The constant force spiral spring is installed in the arc-shaped grooves, and one end of the cross arm is fixedly connected to the U-shaped sheet metal part.

[0012] Preferably, the side wall of the extended column is provided with a clearance slide for avoiding the cross arm, and a baffle for blocking the clearance slide is fixed on one side of the U-shaped sheet metal part.

[0013] Preferably, a decorative panel is installed on the outer side of the cross arm.

[0014] Preferably, the base is equipped with casters at all four corners of its bottom.

[0015] Compared with related technologies, the present invention provides the following beneficial effects: I. Convenient and reliable height adjustment The height locking mechanism, consisting of a V-shaped spring and a limiting post, along with multiple locking holes on the fixed column, allows users to easily adjust the extension height of the column simply by pressing the limiting post. It automatically locks when released, making the operation simple, quick, and reliable.

[0016] II. Smooth lifting and easy hovering. Using a constant force spiral spring as a balancing element, the tension output is constant throughout the entire stroke. In conjunction with the slide rail assembly, the horizontal arm is subjected to uniform force during lifting and lowering, resulting in a smooth feel and stable suspension at any position without the need for an additional locking device.

[0017] III. Compact structure and attractive appearance The slide rail assembly is built into the extension column. The design, which avoids the slide rails and baffles, ensures smooth sliding of the crossarm while preventing the internal structure from being exposed, resulting in a clean overall appearance. Decorative panels can be installed on the outer side of the crossarm to further enhance the product's aesthetics. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 15A telescopic floor stand is mainly supported by a base 1. The top of the base 1 has a mounting hole 10 for accommodating a fixed column 2. The fixed column 2 is hollow, and a connecting plate 11 is installed on the inner side of its bottom end. A sealing plate 13 for sealing the bottom of the mounting hole 10 is fixedly connected to the bottom of the base 1 by screws 12. The sealing plate 13 is fixedly connected to the connecting plate 11 by screws 12, thereby firmly fixing the fixed column 2 to the base 1.

[0022] An extension column 3 is embedded in the top of the fixed column 2. The extension column 3 is hollow, and its bottom end is equipped with a height locking mechanism 4 that cooperates with the fixed column 2. The side wall of the fixed column 2 has several locking holes 14. The height locking mechanism 4 includes a V-shaped spring 15 and a limiting post 16. A bottom plug 17 is embedded in the bottom end of the extension column 3. A V-shaped spring 15 is provided on the inner side of the extension column 3. A limiting post 16 is fixed at the bend of the V-shaped spring 15. The limiting post 16 protrudes from the side wall of the extension column 3 and cooperates with the locking hole 14. Both ends of the V-shaped spring 15 are in contact with the inner wall of the extension column 3. When the height needs to be adjusted, press the limiting post 16 inward to disengage it from the current locking hole 14. Then move the extension column 3 up and down to the desired position, release the limiting post 16, and under the elastic force of the V-shaped spring 15, the limiting post 16 automatically engages into the corresponding locking hole 14, achieving rapid locking.

[0023] The extension column 3 is internally connected to a slide rail assembly 5, which includes a U-shaped sheet metal part 18. Several sliders 19 are fixed to both sides of the U-shaped sheet metal part 18, and the sliders 19 are slidably connected to the extension column 3. A constant force spiral spring 6 is installed inside the slide rail assembly 5. Specifically, several mounting seats 20 are installed inside the U-shaped sheet metal part 18, and each mounting seat 20 has an arc-shaped groove 21. The constant force spiral spring 6 is installed in the arc-shaped groove 21, and its extension end is fixedly connected to the top of the extension column 3. The constant force spiral spring 6 can output a nearly constant tension throughout its entire stroke, used to balance the weight of the cross arm 7 and the equipment it supports.

[0024] A cross arm 7 is mounted on the U-shaped sheet metal part 18, with one end of the cross arm 7 fixedly connected to the U-shaped sheet metal part 18. The side wall of the extension column 3 is provided with a clearance slide 22 to avoid the cross arm 7. A baffle 23 is fixed to one side of the U-shaped sheet metal part 18 to cover the clearance slide 22, preventing the internal structure from being exposed and preventing dust from entering. A decorative panel 24 is installed on the outer side of the cross arm 7 to enhance the overall appearance and texture.

[0025] A dual-axis torque hinge 8 is installed at the end of the cross arm 7, and a mounting plate 9 is fixed to the output end of the dual-axis torque hinge 8. The dual-axis torque hinge 8 provides two orthogonal degrees of rotational freedom, facilitating the adjustment of the pitch and roll angles of the device (such as a tablet computer, monitor, etc.) carried on the mounting plate 9, enabling flexible adjustment at multiple angles. Universal wheels 25 are installed at each of the four corners of the bottom of the base 1 for easy movement.

[0026] The working principle of this telescopic floor stand is as follows: I. Height Adjustment According to the user's needs, press the limiting post 16 to retract it into the extension post 3, releasing its engagement with the locking hole 14. Then, pull the extension post 3 up or down to the appropriate height and release the limiting post 16. Under the elastic restoring force of the V-shaped spring 15, the limiting post 16 automatically pops out and locks into the corresponding locking hole 14 on the fixed post 2, completing the height locking. The entire process can be operated with one hand, making it quick and convenient.

[0027] II. Lifting and Hovering of the Horizontal Arm When the height of the crossarm 7 needs to be adjusted, the user applies an upward or downward force to the crossarm 7. The slide rail assembly 5 slides inside the extension column 3 via the slider 19. The tension end of the constant force spiral spring 6 is fixed to the top of the extension column 3, and its output constant tension acts on the slide rail assembly 5. This tension is set to balance the overall weight of the crossarm 7 and the equipment it supports. Therefore, without external force, the crossarm 7 can be stably suspended at any height; under external force, the crossarm 7 can be smoothly raised and lowered with a uniform feel and no jerking.

[0028] III. Angle Adjustment The mounting plate 9 can be rotated in two axes relative to the crossarm 7 via the dual-axis torque hinge 8. Users can adjust the pitch and roll angles of the mounted equipment as needed to achieve the optimal viewing or usage angle.
