Description

Technical Field

[0001] The utility model relates to the technical field of sliding mechanisms, in particular to a novel up-and-down sliding mechanism. Background Art

[0002] Most of the up-down sliding mechanisms on the current market are mainly designed for linear motion, such as vertical lifting, horizontal movement, etc., but have obvious deficiencies in rotation function. This single-function design limits the application ability of the mechanism in complex tasks and cannot meet the needs of all-round operation or flexible angle adjustment. In the fields of 3D design, simulation, virtual reality, and in the operation and maintenance of certain industrial equipment, users often need to obtain a full view of the object. However, due to the lack of rotation function, the traditional up-down sliding mechanism is limited by the user's viewing angle when observing or operating, and cannot achieve 360-degree all-round viewing and operation. In mechanical design, adding a rotation function often means the need to add additional transmission mechanisms, support structures, control systems and other components, which not only increases the complexity of the design, but may also have an adverse effect on the stability, accuracy and cost of the mechanism. Therefore, many designers tend to choose an up-down sliding mechanism with simpler functions in practical applications.

[0003] Therefore, there is an urgent need for a new type of up and down sliding mechanism to provide an effective solution to the defects of the prior art. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel up and down sliding mechanism comprises an upper base plate and a lower base plate, a guide column frame is rotatably installed between the upper base plate and the lower base plate, a lifting frame is slidably installed on the outer side of the guide column frame, the lower base plate is fixedly installed on the base through a bracket, the guide column frame is driven to rotate by a rotary drive motor, a vertically arranged rack is fixedly installed on the guide column frame, a motor base plate is fixedly connected to the lifting frame, a lifting drive motor is fixedly installed on the motor base plate, a gear is fixedly connected to the output shaft of the lifting drive motor, and the gear is meshed with the rack.

[0007] Furthermore, the guide column frame includes four vertical guide columns, and the upper and lower ends of the vertical guide columns are respectively fixedly connected to the upper disk seat and the lower disk seat, and the lifting frame includes a square profile frame with a cubic structure as the outer contour, and a pair of roller frames arranged perpendicular to each other are fixedly installed on the inner side of each corner of the square profile frame, and guide rollers are rotatably connected to the roller frames, and the circumferential outer walls of the guide rollers are tightly attached to the vertical guide columns.

[0008] Furthermore, an arc groove which fits with the vertical guide column is provided on the circumferential outer wall of the guide roller.

[0010] Furthermore, the lifting frame and the guide column frame are both made of aluminum alloy.

[0011] Furthermore, the lifting frame is made of standard industrial aluminum profiles.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Compared with the traditional mechanism which only has the function of sliding up and down, the utility model integrates the rotation function, which can easily realize full-scale rotation during operation or observation, and meet the requirements of full-scale viewing angle; however, through the ingenious structural design and reasonable transmission mechanism arrangement, the complexity of the structure is not significantly increased; the modular design concept makes it easy to install, debug and maintain the various components.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figures 1 to 5 A novel up and down sliding mechanism includes an upper base plate 6 and a lower base plate 3, a guide column frame 9 is rotatably installed between the upper base plate 6 and the lower base plate 3, a lifting frame 11 is slidably installed on the outer side of the guide column frame 9, the lower base plate 3 is fixedly installed on the base 1 through a bracket 2, the guide column frame 9 is driven to rotate by a rotary drive motor 10, a vertically arranged rack 18 is fixedly installed on the guide column frame 9, a motor base plate 15 is fixedly connected to the lifting frame 11, a lifting drive motor 16 is fixedly installed on the motor base plate 15, a gear 17 is fixedly connected to the output shaft of the lifting drive motor 16, and the gear 17 is meshed with the rack 18.

[0024] The guide column frame 9 includes four vertical guide columns, and the upper and lower ends of the vertical guide columns are fixedly connected to the upper disk seat 5 and the lower disk seat 4 respectively. The lifting frame 11 includes a square profile frame 12 with a cubic structure as the outer contour. A pair of roller frames 13 arranged perpendicular to each other are fixedly installed on the inner side of each corner of the square profile frame 12. A guide roller 14 is rotatably connected to the roller frame 13, and the circumferential outer wall of the guide roller 14 is in close contact with the vertical guide column.

[0025] An arc groove that fits with the vertical guide column is provided on the circumferential outer wall of the guide roller 14.

[0026] The lower surface of the upper base plate 6 and the upper surface of the lower base plate 3 are both fixedly connected with an annular track 7 , and the upper surface of the upper disc seat 5 and the lower surface of the lower disc seat 4 are both installed with a group of rollers 8 , which are slidably installed on the annular track 7 .

[0027] The lifting frame 11 and the guide column frame 9 are both made of aluminum alloy.

[0028] The lifting frame 11 is made of standard industrial aluminum profiles.

[0029] Working principle of this embodiment:

[0030] When the rotation function is required, the rotation drive motor 10 is started to drive the guide column frame 9 to rotate around its axis. Since the guide column frame 9 is rotatably mounted with the upper base plate 6 and the lower base plate 3 through the upper plate seat 5 and the lower plate seat 4, the rotation of the guide column frame 9 can drive all components thereon, including the lifting frame 11 and its load, to rotate 360 ​​degrees in all directions.

[0031] The lifting function is realized by the lifting drive motor 16. The motor 16 is fixedly mounted on the motor base plate 15, and the motor base plate 15 is fixedly connected to the lifting frame 11. When the motor 16 is started, its output shaft drives the gear 17 to rotate, and the gear 17 meshes with the rack 18 fixed on the guide column frame 9, thereby converting the rotational motion into linear motion.

[0032] At the same time, the rollers 8 on the upper disc seat 5 and the lower disc seat 4 slide along the annular tracks 7 on the upper base plate 6 and the lower base plate 3 to ensure stability and accuracy during the rotation process.

[0033] The lifting frame 11 adopts a square profile frame 12 structure, and each corner thereof is provided with a roller frame 13 and a guide roller 14. The circumferential outer wall of the guide roller 14 is in close contact with the vertical guide column, and is provided with an arc groove that fits the vertical guide column to reduce sliding friction and improve the stability of lifting.

[0034] The use of lightweight and high-strength materials such as aluminum alloy to make the lifting frame 11 and the guide column frame 9 not only reduces the overall weight, but also improves the durability and corrosion resistance of the mechanism. At the same time, the application of standardized industrial aluminum profiles reduces the manufacturing difficulty and improves the production efficiency of the product.

[0035] Compared with the traditional mechanism which only has the up and down sliding function, this embodiment integrates the rotation function, which can easily realize 360-degree rotation during operation or observation to meet the requirements of all-round viewing angle; but through clever structural design and reasonable transmission mechanism arrangement, the complexity of the structure is not significantly increased; the modular design concept makes it easy to install, debug and maintain the components.
