[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-3 An adjustable tablet computer support includes a connecting rod 12. A set of ball heads 13 are fixedly provided on both the upper and lower sides of the connecting rod 12. Insertion holes are evenly provided on the outer side wall of the ball head 13. A ball head seat 11 is rotatably sleeved on the outer side wall of the ball head 13. A through hole is provided on the rear side of the ball head seat 11, and the through hole corresponds to the insertion hole. A locking component is placed on the rear side of the ball head seat 11.
[0019] The locking assembly includes a connecting plate 131. A pull ring 132 is fixedly disposed on the rear side of the connecting plate 131. A first internal thread groove is formed on the front side of the connecting plate 131. A connecting ring 133 is placed on the front side of the connecting plate 131. A second internal thread groove is formed on the rear side of the connecting ring 133. A first external thread ring 135 is screwed into the first internal thread groove. A second external thread ring 136 is screwed into the second internal thread groove. A spring 137 is fixedly disposed between the first external thread ring 135 and the second external thread ring 136. A pin 134 is fixedly disposed on the front side of the connecting plate 131. The connecting ring 133 and the spring 137 are both located on the outer ring of the pin 134. The connecting ring 133 is fixedly disposed on the rear side of the ball head seat 11. The side of the pin 134 away from the connecting plate 131 passes through the through hole of the ball head seat 11 and is inserted into the ball head seat 11. Pulling the pull ring 132 backward through the ball head 131 causes the pin 134 to separate from the ball head 13. At this time, the ball head seat 11 can be tilted at an angle on the outer side wall of the ball head 13. When the ball head 13's insertion hole is aligned with the pin 134, the pull ring 132 is released. The spring 137 uses its own rebound force to drive the pin 134 to insert into the ball head 13's insertion hole through the connecting plate 131, thereby fixing the ball head seat 11 on the outer side of the ball head 13. When the spring force of the spring 137 decreases, rotating the connecting plate 131 can separate the connecting plate 131 from the first external threaded ring 135. Then, rotating the first external threaded ring 135 causes the second external threaded ring 136 to separate from the connecting ring 133 through the spring 137. In this way, the spring 137 can be removed and replaced.
[0020] In the two sets of ball joint seats 11, a base 1 is fixedly installed at the bottom of the lower ball joint seat 11. In the two sets of ball joint seats 11, a support plate 2 is fixedly installed at the top of the upper ball joint seat 11. A sliding groove is opened at the top of the support plate 2, and a double-acting screw 21 is rotatably installed in the sliding groove. The front side of the double-acting screw 21 passes through the front side of the support plate 2 and is connected to a handwheel 25. Internally threaded sliders 22 are evenly screwed onto the outer side wall of the double-acting screw 21. The two sets of internally threaded sliders 22 are evenly slidably installed in the sliding groove. Two sets of guide holes are evenly opened on the front and rear sides of the support plate 2, respectively. The guide holes are connected to the sliding groove of the support plate 2. Two sets of guide rods 23 are evenly fixed on opposite sides of the threaded slider 22. The guide rods 23, away from the internal threaded slider 22, pass through the guide hole of the tray 2 and are connected to the clamping block 24. Rotating the handwheel 25 drives the bidirectional screw 21 to rotate, which in turn drives the two sets of internal threaded sliders 22 to slide outward. The internal threaded sliders 22 drive the clamping block 24 to move outward through the guide rods 23, placing the tablet computer on the tray 2. Then, rotating the handwheel 25 in the opposite direction drives the bidirectional screw 21 to rotate, thereby driving the clamping block 24 to move inward and clamp and fix the tablet computer on the tray 2.
[0021] Working principle: Rotating the handwheel 25 drives the double-acting screw 21 to rotate, which in turn drives the two sets of internal threaded sliders 22 to slide outward. The internal threaded sliders 22, through the guide rod 23, drive the clamping block 24 to move outward, placing the tablet computer on the tray 2. Then, rotating the handwheel 25 in the opposite direction drives the double-acting screw 21 to rotate, thereby driving the clamping block 24 to move inward, clamping and fixing the tablet computer on the tray 2. Pulling the pull ring 132 backward causes the pin 134 to separate from the ball head 13 through the connecting plate 131. At this time, the ball head seat 11 can be tilted at an angle on the outer wall of the ball head 13. With the ball head 13 aligned with the pin 134, the pull ring 132 is released. The spring 137 uses its own rebound force to drive the pin 134 into the ball head 13 through the connecting plate 131, thereby fixing the ball head seat 11 to the outside of the ball head 13. When the spring force of the spring 137 decreases, the connecting plate 131 can be screwed away from the first external threaded ring 135 by rotating the connecting plate 131. Then, the first external threaded ring 135 is rotated to drive the second external threaded ring 136 to be screwed away from the connecting ring 133 through the spring 137, thereby allowing the spring 137 to be removed and replaced.
