Description

Technical Field

[0001] The utility model relates to the technical field of IPAD clamping and fixing, in particular to a clamping mechanism for IPAD. Background Technique

[0002] The clamping mechanism for iPad is a device designed to stably support and fix the iPad. The clamping mechanism usually uses metal or high-strength plastic as the main material, and the part in contact with the iPad may use soft silicone or rubber pads. Common clamping methods include up-and-down clamping and side clamping. The clamping mechanism for iPad is usually used in scenarios such as learning, office work, and entertainment.

[0003] For example, the Chinese patent "A Fixing Device for iPad Photographing" with the publication number CN220269247U includes a base, a light box, a first LED lamp bead, a second LED lamp bead, a housing, an annular lamp cover, a rear cover, and an infrared remote control receiver. The light box is arranged in a cuboid structure, the light box is vertically arranged on the base, the first LED lamp beads are respectively arranged in the light box, a light-transmitting lamp cover is arranged at the front end of the light box, the outer contour of the housing is arranged in a circular structure, the lower end wall of the housing is rotatably connected to the upper end wall of the light box up and down, the annular lamp cover covers the front end of the housing, the second LED lamp beads are respectively arranged in the annular lamp cover along the circumferential direction, a notch groove adapted to the rear cover is concavely arranged in the middle of the rear end wall of the housing, first limiting flanges are respectively convexly arranged on the inner side walls of the front end and the rear end of the notch groove along the circumferential direction, the rear cover is detachably embedded in the rear end of the notch groove, a first limiting plate is convexly arranged on the lower end wall of the rear cover, first limiting grooves are respectively concavely arranged on both sides of the inner side wall of the rear end of the notch groove, the first limiting plate is detachably embedded in the first limiting grooves, the upper end of the rear cover is detachably fixedly connected to the rear end wall of the housing, second limiting plates are respectively convexly arranged on both sides and the upper end of the front end wall of the rear cover, and the iPad is detachably embedded in the notch groove.

[0004] Although the above-mentioned prior art can realize the clamping and fixing of the iPad, in actual use, on the one hand, it is difficult to fix the position of the telescopic plate. Usually, the iPad is clamped and fixed by the way of spring extrusion with the telescopic plate, resulting in deformation of the side of the iPad due to excessive extrusion, thus causing damage to the iPad. On the other hand, the telescopic plate is prone to shaking during the movement process, and is prone to position deviation during the process of pulling the telescopic plate out of the telescopic cavity, resulting in difficulty in moving the telescopic plate to the precise position, thereby affecting the clamping accuracy of the telescopic plate. Therefore, it does not meet the existing requirements, and for this reason, we propose a clamping mechanism for IPAD. Summary of the Invention

[0012] Preferably, four fixing buckles are fixedly arranged on both sides of the rear end of the base exterior, and the fixing buckles are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) Through the pawl and the second rack, the present utility model can fix the position of the telescopic plate. Before pulling the telescopic plate, the labyrinth lock assembly is unlocked. At this time, press down the adjusting plate. Under the pulling force of the coil spring, the adjusting plate pops outwards. At this time, the pawl pops out together in the avoidance track. After the adjusting plate pops out, the pawl enters the working track under the push of the third return spring. At this time, push down the adjusting plate again, and the lower end of the adjusting plate squeezes the pawl, so that the pawl rotates on the first bolt and retracts into the telescopic plate. At the same time, the third return spring is in a stretched state until the telescopic plate is adjusted to a suitable position and the adjusting plate is released. At this time, through the reset of the third return spring, the pawl is re-rotated into the working track and contacts the second rack, so that the pawl is clamped and fixed with the second rack, thereby completing the fixation of the telescopic plate. When the adjusting plate is pushed to the bottom, the lower end of the adjusting plate squeezes the pawl, so that the pawl moves vertically inwards outside the first bolt. At the same time, the third return spring is in a compressed state again. At this time, the pawl enters the avoidance track again, thereby improving the flexibility of the telescopic plate fixation.

[0015] (2) Through the second bolt and the damping wheel assembly, the present utility model can improve the stability of the telescopic plate during the stretching process. When pulling the telescopic plate, the labyrinth lock assembly is unlocked. At this time, the telescopic plate slides outwards from the telescopic cavity. During the process of the telescopic plate sliding outwards, the fixed second bolt slides in the chute. At the same time, the damping wheel assembly rotates at a constant speed under the drive of the first rack. Through the second bolt and the chute, the telescopic plate reduces position deviation during the stretching process. At the same time, the damping wheel assembly and the first rack can improve the stability of the telescopic plate during stretching, thereby improving the movement accuracy of the telescopic plate. [[ID=,13]]

[0016] (3) The utility model can lock the telescopic plate through the labyrinth lock assembly and the limiting groove. When it is necessary to lock the telescopic plate, the operator uses a tool to rotate the threaded rod on the labyrinth lock assembly at this time, so that the threaded rod drives the labyrinth lock assembly to rotate until the labyrinth lock assembly is rotated to an inclined state. At this time, the protrusion at the rear end of the labyrinth lock assembly is clamped and fixed with the inner wall of the limiting groove, avoiding the accidental sliding out of the telescopic plate when it is not in use, thereby improving the safety of the clamping mechanism.

At the same time, the third return spring 11 is in a stretched state. Until the telescopic plate 2 is adjusted to the appropriate position and the adjusting plate 4 is released, at this time, through the reset of the third return spring 11, the pawl 9 is rotated back into the working track 21 and contacts the second rack 22, so that the pawl 9 is clamped and fixed with the second rack 22. When the adjusting plate 4 is pushed to the bottom, the lower end of the adjusting plate 4 squeezes the pawl 9, so that the pawl 9 moves vertically inwards outside the first bolt 8. At the same time, the third return spring 11 is in a compressed state again. At this time, the pawl 9 enters the avoidance track 23 again. When pulling the telescopic plate 2, at this time, the telescopic plate 2 slides outwards from the telescopic cavity 5. During the process of the telescopic plate 2 sliding outwards, the fixed second bolt 15 slides in the chute 14. At the same time, the damping wheel assembly 13 rotates at a constant speed under the drive of the first rack 18. When it is necessary to lock the telescopic plate 2, at this time, the operator uses a tool to rotate the threaded rod on the labyrinth lock assembly 12, so that the threaded rod drives the labyrinth lock assembly 12 to rotate until the labyrinth lock assembly 12 is rotated to an inclined state. At this time, the protrusion at the rear end of the labyrinth lock assembly 12 is clamped and fixed with the inner wall of the limiting groove 17.
