Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] like Figures 1 to 6 As shown, where Figure 1 This is a schematic diagram of the overall structure of the turntable snap-fit ​​mechanism. Figure 2 This is a structural schematic diagram of gear 112. Figure 3 This is a structural schematic diagram of the dovetail groove 107. Figure 4 yes Figure 3 Enlarged view of point A in the middle. Figure 5 This is a structural diagram of the split plastic ring 105. Figure 6 This is a schematic diagram of the internal gear ring 110 mounting a cross-connector. This utility model provides a turntable snap-fit ​​structure: including a base 101, a first pressure plate 102, a second pressure plate 103, a mating block 104, a split plastic ring 105, and a driving device. The driving device includes the internal gear ring 110 and a power assembly, which includes a reducer 111 and a gear 112. The aforementioned solution solves the problem of high wear caused by direct contact in existing turntable snap-fit ​​structures. It is understood that the aforementioned solution can optimize the structure and reduce wear.

[0024] In this embodiment, the base 101 is used for mounting support and rotation support of the turntable 106.

[0025] The base 101 is provided with a first pressure plate 102, which is detachably connected to a second pressure plate 103. A mating block 104 is provided between the first pressure plate 102 and the second pressure plate 103. Both the first pressure plate 102 and the second pressure plate 103 have a wear-resistant plastic layer on their surfaces, with metal components inside. During installation, the wear-resistant plastic layer is directly applied to the outer surface of the metal components of the first pressure plate 102 and the second pressure plate 103, which have corresponding shapes and structures, to improve wear resistance and provide contact isolation. The first pressure plate 102 is fixed to the base 101 with bolts, and the second pressure plate 103 is connected to the first pressure plate 102 with bolts. The first pressure plate 102 has an installation groove to facilitate the installation of the mating block 104. The fixing bolts of the second pressure plate 103 pass through the vertical through hole of the mating block 104. The mating block 104 is used for the abutment and support of the split plastic ring 105, which helps to improve stability.

[0026] Two separate plastic rings 105 are disposed between the first pressure plate 102 and the second pressure plate 103, and are engaged within the dovetail groove 107 and rectangular groove 108 of the turntable 106, with the ends of the two separate plastic rings 105 pressed together vertically. Corresponding mounting portions are provided on each of the two separate plastic rings 105 to engage with the dovetail groove 107 and rectangular groove 108 for installation. Simultaneously, the assembled first pressure plate 102 and second pressure plate 103 further limit their position. The dovetail groove 107 and rectangular groove 108 are evenly spaced in a ring, which facilitates multi-point positioning assistance during installation of the two separate plastic rings 105, improving their installation stability.

[0027] The drive device is located on the base 101 near the turntable 106. The drive device is used to drive the turntable 106 to rotate for angle adjustment.

[0028] Secondly, the base 101 is also provided with a plurality of guide rolled edges 109 evenly spaced in a ring. The guide rolled edges 109 slide in engagement with the mating rolled edges on the turntable 106. The guide rolled edges 109 are detachable parts and can be replaced after wear. The mating rolled edge surface is provided with a wear-resistant coating to improve its service life.

[0029] Then, the internal gear ring 110 is connected to the turntable 106 via a cross connecting bracket and is located on the top side of the turntable 106; the power assembly is located on the base 101 near the internal gear ring 110. The internal gear ring 110 is connected to the cross connecting bracket by bolts, and the four ends of the cross connecting bracket are respectively connected to the turntable 106 by bolts. This structure facilitates the rotation of the gear 112 after the reducer 111 rotates, which in turn drives the turntable 106 to rotate, thereby achieving adjustment.

[0030] Furthermore, the reducer 111 is mounted on the base 101; the gear 112 is mounted on the output shaft of the reducer 111 and meshes with the internal gear ring 110. The motor mounting bracket of the reducer 111 is connected to the base 101 by bolts, and the reducer 111 is mounted on the motor mounting bracket by bolts. The gear 112 is mounted on its output shaft by a flat key and locking bolts. The gear 112 meshes with the internal gear ring 110. During adjustment, the reducer 111 is controlled to rotate, thereby rotating the gear 112. The rotation of the gear 112 will drive the turntable 106 to rotate, thereby realizing angle adjustment.

[0031] Finally, an abutment piece 113 is provided on one side of the mating block 104. The abutment piece 113 is directly disposed in the gap between the mating block 104 and the first pressure plate 102 for the mating block 104 to be installed and mated. At the same time, after the second pressure plate 103 is installed, the mating block 104 can be limited under the action of the first pressure plate 102 and the second pressure plate 103 to prevent it from moving vertically.

[0032] When using this invention to solve the problem of excessive wear caused by direct contact in the turntable snap-fit ​​structure in the prior art, firstly, the two separate plastic rings 105 are made of wear-resistant plastic material and are directly snapped into the multiple dovetail grooves 107 and multiple rectangular grooves 108 of the turntable 106 during installation. The ends of the two separate plastic rings 105 are pressed together vertically to form an annular isolation structure. Furthermore, the first pressure plate 102 and the second pressure plate 103 cooperate to limit the position of the separate plastic rings 105, ensuring a stable annular isolation structure. Both the first pressure plate 102 and the second pressure plate 103 are respectively provided with wear-resistant plastic layers to isolate the turntable 106 during rotation and prevent direct contact. Finally, the reducer 111 is controlled to drive the gear 112 to rotate. After the gear 112 rotates, it will drive the turntable 106 to rotate, thereby realizing adjustment. When the turntable 106 rotates, the two split plastic rings 105 can isolate the base 101 and the turntable 106 to avoid direct contact, thus solving the problem of high wear caused by direct contact in the turntable snap-fit ​​structure in the prior art.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
