Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile device installation structure technology, and specifically to an external anti-creep mechanism. Background Technology
[0002] In the field of automation equipment, many mobile devices need to slide horizontally. Currently, the common practice is to fix the mobile device on a guide rail and control its movement on the guide rail to achieve the desired effect. However, the sliding of the mobile device may cause creeping along the guide rail, resulting in inaccurate positioning.
[0003] Therefore, based on the aforementioned shortcomings of the existing mobile device mounting structure, it is necessary to improve the existing mobile device mounting structure. Utility Model Content
[0004] The purpose of this utility model is to provide an external anti-creep mechanism to address the shortcomings of existing technologies. This external anti-creep mechanism solves the defects of existing mobile device installation structures, such as inaccurate positioning.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0006] An external anti-creep mechanism includes a base with a mounting groove. A left fixed guide rail and a right fixed guide rail are fixedly mounted on the left and right sides of the mounting groove, respectively. A movable guide rail is slidably arranged between the left and right fixed guide rails. A rack is fixed to the top of the movable guide rail. A left gear and a right gear are respectively mounted on the upper ends of the left and right fixed guide rails, and the left gear and the right gear mesh with the left and right sides of the rack, respectively.
[0007] Furthermore, rollers are embedded between the moving guide rail and the left and right fixed guide rails respectively, which can ensure that the moving guide rail moves smoothly.
[0008] Furthermore, the inner sides of the seat are respectively formed with clearance positions to avoid the left gear and the right gear, thereby reducing the volume of the seat.
[0009] Furthermore, the left and right gears are compound gears, with the toothed edges of the rack meshing with the upper gears of the left and right gears respectively, and the lower parts of the left and right gears also having coaxial gears.
[0010] Furthermore, the left and right fixed guide rails each have a fixing frame on their sides. The lower end of the fixing frame is vertical and has multiple limiting holes. The rollers are embedded in the limiting holes of the fixing frame, which can keep the rollers in stable contact with the moving guide rail.
[0011] Furthermore, the upper end of the fixing frame has toothed edges that mesh with the lower gears of the left gear and the right gear respectively. The left gear and the right gear can simultaneously mesh with the rack and the fixing frame, forming a mutual influence.
[0012] Furthermore, the sides of the left fixed guide rail, right fixed guide rail, and moving guide rail are all formed with sliding grooves along the axis. The rollers of one fixed frame are respectively embedded between the sliding grooves of the left fixed guide rail and the moving guide rail, and the rollers of another fixed frame are respectively embedded between the sliding grooves of the right fixed guide rail and the moving guide rail, so that the moving guide rail moves stably relative to the left fixed guide rail and the right fixed guide rail.
[0013] Furthermore, the rollers are set at 45 degrees, and the opening of the sliding groove is at 45 degrees, resulting in a more balanced force distribution.
[0014] The beneficial effects of this utility model are as follows: when the moving device moves, it moves together with the rack and the moving guide rail. Since the rack meshes with the left gear and the right gear, the moving device will not creep, thereby achieving accurate positioning. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] See Figure 1 —— Figure 4 This utility model discloses an external anti-creep mechanism comprising: a base 1, with a mounting groove 2 formed along the axial direction of the base 1; a left fixed guide rail 3 and a right fixed guide rail 4 fixedly mounted on the left and right sides of the mounting groove 2, respectively; a movable guide rail 5 slidably disposed between the left and right fixed guide rails 3 and 4; and a rack 6 fixedly mounted on the top of the movable guide rail 5, with toothed edges on the left and right sides of the rack 6. A moving device is fixedly mounted on the rack 6 and the movable guide rail 5.
[0023] In this invention, a left gear 7 and a right gear 8 are respectively installed on the upper ends of the left fixed guide rail 3 and the right fixed guide rail 4. The left gear 7 and the right gear 8 mesh with the toothed edges on the left and right sides of the rack 6, respectively. The inner side of the base 1 is formed with clearance positions 11 to avoid the left gear 7 and the right gear 8.
[0024] When the moving device moves, it moves together with the rack 6 and the moving guide rail 5. The rack 6 drives the left gear 7 and the right gear 8 to rotate. Due to the design of the left gear 7 and the right gear 8, the moving device will not creep.
[0025] The left gear 7 and right gear 8 of this utility model are compound gears, and the tooth edges of the rack 6 mesh with the upper gears of the left gear 7 and right gear 8 respectively.
[0026] The left fixed guide rail 3 and the right fixed guide rail 4 of this invention have fixing brackets 9 on their sides. The fixing brackets 9 are L-shaped, with a horizontal upper end and toothed edges, and a vertical lower end with multiple limiting holes. The toothed edges of the fixing brackets 9 mesh with the lower gears of the left gear 7 and the right gear 8. The rotation of the left gear 7 and the right gear 8 drives the fixing brackets 9 to move together. Rollers 10 are embedded in the limiting holes of the fixing brackets 9. Sliding grooves 12 are formed along the axis on the sides of the left fixed guide rail 3, the right fixed guide rail 4, and the moving guide rail 5. One roller 10 of the fixing bracket 9 is respectively embedded between the sliding grooves 12 of the left fixed guide rail 3 and the moving guide rail 5, and another roller 10 of the fixing bracket 9 is respectively embedded between the sliding grooves 12 of the right fixed guide rail 4 and the moving guide rail 5. The rollers 10 are set at a 45-degree angle, and correspondingly, the opening of the sliding groove 12 is at a 45-degree angle.
[0027] With the design of roller 10, when the moving guide rail 5 and rack 6 move relative to the left fixed guide rail 3 and right fixed guide rail 4, they will drive the left gear 7 and right gear 8 to rotate, thereby driving the fixed frame 9 to move. Roller 10 is always located between the moving guide rail 5 and the left fixed guide rail 3 and right fixed guide rail 4, thus ensuring that the moving guide rail 5 moves smoothly.
[0028] Of course, the above-described embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of the claims of this utility model.
