Abstract
Description
Technical Field
[0001] This utility model relates to the field of gasket structure technology, and in particular to a gasket die-casting structure for a notebook hinge. Background Technology
[0002] The pads used in laptop hinges are mainly for providing support and shock absorption, reducing wear on the hinge, maintaining the stability and durability of the laptop, preventing the hinge from loosening after prolonged use, and ensuring the hinge functions properly.
[0003] During prolonged rotation of the shaft, the shims will wear and loosen. After secondary tightening, the connecting parts on both sides of the shims will deform due to the squeezing force, resulting in poor shaft rotation and situations where the shaft is too tight or too loose.
[0004] To address the aforementioned issues, we propose a die-cast pad structure for notebook hinges. Utility Model Content

The left end of the rotating cylinder is horizontally connected to a limiting block and engages with both ends of a limiting ring. A first sliding groove and two second sliding grooves are provided on the outer wall of the rotating cylinder. The first sliding groove and the two second sliding grooves are located at the two ends of the rotating cylinder, and the two second sliding grooves are set close to the limiting block. A locking washer is slidably inserted in both first sliding grooves. A locking washer is slidably sleeved on the fixed shaft, and its left end is in contact with the right end of the limiting washer. Two elastic washer rings are provided between the locking washer and the locking washer, and are slidably sleeved on the insertion rod.
[0008] In the above-mentioned die-cast pad structure for a notebook hinge, a fixed frame is slidably inserted into the slide groove, and a fixed sleeve of the same width as the fixed frame is provided at the rear end of the fixed frame and located between the rotating cylinder and the insertion rod. A threaded rod is horizontally connected to the right end of the insertion rod, and a threaded sleeve is fitted on the threaded rod.
[0009] In the above-mentioned die-cast shim structure for a notebook hinge, the limiting ring on the limiting shim does not contact the hole on the limiting shim, the right end of the limiting ring and the right end of the insert block are on the same horizontal plane, and the ports at both ends of the limiting ring are arc-shaped.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-3 A die-cast pad structure for a laptop hinge includes a rotating bracket 1. The outer wall of the rotating bracket 1 has two grooves of different sizes, a first groove and a second groove. The first groove is elliptical in shape and has a horizontally positioned fixed shaft 2 slidably inserted into it. The fixed shaft 2 includes a fixed block, a baffle, and a rod, with the length of the fixed block being less than the length of the rod. The baffle on the fixed shaft 2 is fixedly fitted onto the fixed block, and the shape of the fixed block matches that of the first groove. A limiting pad 3 is slidably inserted into the fixed block and located to the right of the baffle. A horizontal connection is made to the outer wall of the limiting pad 3. The insert 4 is slidably inserted into the groove 1, and together with the hole in the center of the limiting pad 3, it fixes the limiting pad 3 so that it will not tilt. The side of the limiting pad 3 away from the baffle is vertically provided with a crescent-shaped limiting ring 5 and its outer side wall is connected to the insert 4. The limiting ring 5 on the limiting pad 3 does not contact the hole on the limiting pad 3. The right end of the limiting ring 5 is on the same horizontal plane as the right end of the insert 4, and the ports at both ends of the limiting ring 5 are arc-shaped. When the arc-shaped ports play a limiting role, they will also reduce the occurrence of hard collisions and reduce wear.
[0021] A rotating cylinder 6 is slidably sleeved on the insertion rod of the fixed shaft 2. The left end of the rotating cylinder 6 is horizontally connected to a limiting block and engages with both ends of the limiting ring 5. A first sliding groove and two second sliding grooves are provided on the outer wall of the rotating cylinder 6. The first sliding groove and the two second sliding grooves are located at both ends of the rotating cylinder 6, and the two second sliding grooves are set close to the limiting block. A locking washer 7 is slidably inserted in the two first sliding grooves. The locking washer 7 includes a ring sleeve, two locking blocks 8 and a limiting sleeve 9. The two ends of the two locking blocks 8 are provided with arc end faces with the same curvature as the outer surface of the rotating cylinder 6, so that the locking washer 7 and the outer wall of the rotating cylinder 6 together form a smooth arc surface, which facilitates the installation and movement of the laptop hinge and will not affect the rotation and installation of the rotating cylinder 6 due to the protrusion of the outer edge of the locking block 8. The limiting sleeve 9 has a notch and is aligned with the two locking blocks 8. The locking pad 10 is slidably fitted on the fixed shaft 2, and its left end is in contact with the right end of the limiting pad 3. The locking pad 10 is provided with a limiting sleeve 11. The limiting sleeve 11 is the same size as the limiting sleeve 9 and is set opposite to it. Two elastic washers 12 are provided between the locking pad 7 and the locking pad 10 and are slidably fitted on the insert rod. The two elastic washers 12 are respectively inserted into the limiting sleeve 9 and the limiting sleeve 11 to fix it. However, during subsequent tightening, it can prevent the two elastic washers 12 from being deformed by the squeezing force and the deformed part from moving between the locking pad 7 and the insert rod or tilting, which would affect the rotation of the shaft.
[0022] A fixed frame 13 is slidably inserted into the chute. A fixed sleeve of the same width as the fixed frame 13 is provided at the rear end of the fixed frame 13 and is located between the rotating drum 6 and the insert rod. A threaded rod is horizontally connected to the right end of the insert rod. A threaded sleeve 14 is fitted on the threaded rod. The outer diameter of the threaded sleeve 14 is smaller than the outer diameter of the rotating drum 6.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
