Description

Technical Field

[0001] This utility model relates to the field of rotary seat technology, specifically to a rotary seat that is convenient for limiting and fixing. Background Technology

[0002] A swivel seat, as a device or structure capable of rotating around a certain axis, is widely used in various mechanical equipment, amusement facilities, car seats, and other fields. Its main function is to provide rotational freedom, allowing the connected equipment or components to be rotated and adjusted as needed to meet specific operational or user experience requirements.

[0003] The rotating base disclosed in patent CN211176074U is assembled from three parts. The foot pad is installed at the bottom of the lower cover for support. The lower cover and the upper cover are slidably connected by a ring slide rail pair, allowing the upper cover to rotate 360° around the lower cover. The display screen is installed and fixed on the upper cover, so the display screen can be rotated and its position adjusted directly. This utility model has the advantages of simple structure, convenient assembly, low cost and high stability.

[0004] While the top cover of this rotating stand can rotate 360° around the bottom cover, it does have some shortcomings in practical applications. Specifically, it lacks a locking mechanism, meaning the top cover cannot be locked after rotating to a certain angle. The design of this rotating stand primarily focuses on structural simplification and cost reduction, achieving basic functionality through the assembly of three main components. However, this design does not consider the user's need to lock the display at specific angles. Because of the lack of a locking mechanism, the top cover cannot lock after rotation, which could lead to the display rotating due to accidental touch or external force during use, thus affecting the user's viewing and operating experience.

[0005] Therefore, it is necessary to invent a rotary seat that is convenient for limiting and fixing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rotary seat that is convenient for limiting and fixing, so as to solve the problems in the above-mentioned technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotary seat for convenient positioning and fixing, comprising a top plate and a chassis, wherein the top plate is disposed on the top of the chassis, and a positioning component is disposed on each of the two sides of the bottom of the top plate. The positioning component includes an L-shaped loading plate, the top of the L-shaped loading plate is fixedly connected to the bottom edge of the top plate, the bottom end of the L-shaped loading plate hangs below the bottom edge of the chassis, an adjusting bolt is threadedly connected to the middle of the bottom end of the L-shaped loading plate, a knob is fixedly connected to the bottom end of the adjusting bolt, a pressing plate is fixedly connected to the top of the adjusting bolt, and an anti-slip rubber pad is fixedly connected to the top of the pressing plate, the top surface of the anti-slip rubber pad abutting against the bottom of the chassis.

[0008] By designing a limiting component, the limiting and fixing function of the rotating seat is realized. Utilizing components such as an L-shaped loading plate, adjusting bolts, knobs, compression plates, and anti-slip rubber pads, the fixing state between the top plate and the chassis can be easily adjusted, improving the flexibility and stability of the rotating seat.

[0009] Preferably, a cross assembly block is fixedly connected to the center of the bottom of the top plate, and a rotating shaft is rotatably connected to the center of the top of the chassis. A cross assembly groove is opened at the top of the rotating shaft, and the cross assembly block is engaged with the cross assembly groove.

[0010] The cross-shaped assembly block at the bottom center of the top plate engages with the rotating shaft and cross-shaped assembly slot at the top center of the chassis, achieving a simple and reliable rotational connection between the top plate and the chassis. This connection method is not only easy to assemble and disassemble, but also ensures the stability of the top plate during rotation.

[0011] Preferably, a roller is installed at the bottom of the top plate, and an annular groove is formed at the top edge of the chassis, with the roller slidably connected to the annular groove.

[0012] Rollers are installed at the bottom of the top plate, and an annular groove is opened at the top edge of the chassis, so that the top plate can rotate smoothly relative to the chassis. The sliding connection design between the rollers and the annular groove reduces frictional resistance and improves the smoothness of rotation.

[0013] Preferably, the number of rollers is set to multiple, and the multiple rollers are distributed in a circular array.

[0014] The design of multiple rollers can distribute the pressure of the top plate weight on individual rollers, extending the service life of the rollers.

[0015] Preferably, a fixing ring is provided directly below the chassis, and a support column is fixedly connected between the chassis and the fixing ring, and the support column does not contact the bottom end of the L-shaped loading plate.

[0016] The raised column serves two purposes: firstly, it supports the rotating base, and secondly, by raising the chassis, it prevents the L-shaped loading plate of the limiting component from touching the mounting platform.

[0017] Preferably, the number of the elevated columns is set to multiple, and the multiple elevated columns are distributed in a ring array.

[0018] Setting up multiple elevated columns in a circular array improves the stability and load-bearing capacity of the rotating base. This design ensures that the rotating base is subjected to more even force, avoiding damage caused by excessive local stress.

[0019] Preferably, the surface of the fixing ring is provided with a plurality of mounting holes, and the plurality of mounting holes are arranged alternately with the plurality of elevated columns.

[0020] Multiple mounting holes are made on the surface of the fixed ring and are staggered with the support column to facilitate the fixed installation of the rotating seat.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. The design of the limiting component realizes the limiting and fixing function of the rotating seat. The adjusting bolt, extrusion plate and anti-slip rubber pad in the limiting component work together to lock the top plate after it is rotated to the required angle, which avoids rotation due to accidental contact or external force, and improves the stability and safety of the rotating seat.

[0023] 2. The top plate is connected to the chassis shaft by a cross assembly block, achieving a rotatable connection. At the same time, the sliding design of the rollers in the annular groove allows the top plate to rotate smoothly. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figure 1-7 The rotating seat shown includes a top plate 1 and a chassis 2. The top plate 1 is located on top of the chassis 2. A limiting component 3 is provided on each side of the bottom of the top plate 1. The limiting component 3 includes an L-shaped loading plate 4. The top of the L-shaped loading plate 4 is fixedly connected to the bottom edge of the top plate 1. The bottom end of the L-shaped loading plate 4 hangs below the bottom edge of the chassis 2. An adjusting bolt 5 is threadedly connected to the middle of the bottom end of the L-shaped loading plate 4. A knob 6 is fixedly connected to the bottom end of the adjusting bolt 5. A pressing plate 7 is fixedly connected to the top of the adjusting bolt 5. An anti-slip rubber pad 8 is fixedly connected to the top of the pressing plate 7. The top surface of the anti-slip rubber pad 8 abuts against the bottom of the chassis 2.

[0035] In one aspect of this embodiment, a cross-shaped assembly block 9 is fixedly connected to the bottom center of the top plate 1, and a rotating shaft 10 is rotatably connected to the top center of the chassis 2. A cross-shaped assembly groove 11 is provided at the top of the rotating shaft 10, and the cross-shaped assembly block 9 is engaged with the cross-shaped assembly groove 11. A roller 12 is installed at the bottom of the top plate 1, and an annular sliding groove 13 is provided at the top edge of the chassis 2. The roller 12 is slidably connected to the annular sliding groove 13. The number of rollers 12 is set to multiple, and the multiple rollers 12 are distributed in a circular array. A fixing ring 14 is provided directly below the chassis 2, and a support column 15 is fixedly connected between the chassis 2 and the fixing ring 14. The support column 15 does not contact the bottom end of the L-shaped loading plate 4. The number of support columns 15 is set to multiple, and the multiple support columns 15 are distributed in a circular array. The surface of the fixing ring 14 is provided with multiple mounting holes 16, and the multiple mounting holes 16 and the multiple support columns 15 are arranged alternately.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual appendix Figure 1-7When using this utility model, the top plate 1 is first engaged with the cross assembly block 9 at its bottom and the cross assembly groove 11 on the rotating shaft 10 at the top of the chassis 2 to achieve a rotational connection between the top plate 1 and the chassis 2. At the same time, the roller 12 at the bottom of the top plate 1 will slide in the annular groove 13 at the top of the chassis 2, so that the top plate 1 can rotate smoothly relative to the chassis 2.

[0038] When the top plate 1 is rotated to a certain angle and needs to be locked, the knob 6 in the limiting assembly 3 can be rotated. The knob 6 drives the adjusting bolt 5 to rotate in the L-shaped loading plate 4, thereby pushing the extrusion plate 7 and the anti-slip rubber pad 8 on its top to move upward until the anti-slip rubber pad 8 generates sufficient friction with the bottom of the chassis 2, thereby achieving the limiting and fixing of the top plate 1.

[0039] In addition, the fixing ring 14 and the support column 15 directly below the chassis 2 not only provide additional support and stability, but also allow the entire rotating seat to be easily fixed and installed through the mounting holes 16 on the surface of the fixing ring 14.
