Description

Technical Field:

[0001] The utility model relates to a self-locking device for a computer bracket, belonging to the technical field of computer brackets. Background Art:

[0002] With the progress of the times and the development of technology, there are many things that are indispensable in modern people's lives. Among them, the most important one is the "computer", which is a product of the information age. It brings convenience and speed to each of our lives, and besides helping people complete their work, it also provides leisure and entertainment for us to kill time.

[0003] Notebook computers are becoming more and more popular. Notebook computers are much smaller in volume than desktop computers, are convenient to carry and store, and their functions are getting closer and closer to those of desktop computers. They are deeply loved by users, and their demand is also increasing. Existing notebook computers are mainly composed of a display screen and a main body keyboard. There is no special support frame and they can only be placed on a platform board for use, which makes the height of the notebook computer fixed, not conducive to the operation of the user. Moreover, the bottom surface of the notebook computer is in large-area contact with the platform board, which is not conducive to heat dissipation. If the notebook computer is used for a long time, the temperature will be too high, resulting in a decline in the performance of the notebook computer and even affecting the service life of the notebook computer.

The adjusting self-locking device is composed of an upper gear, a lower gear, a screw, a nut, a rotating rod, a positioning screw, a positioning nut, a rod seat, an upper locking rod, a lower locking rod and a spring. The upper gear is fixed on the adjusting plate, and the lower gear is fixed on the bottom plate. The upper gear and the lower gear are designed to be staggered, and after folding, it is a planar structure. The upper gear and the lower gear are connected to the upper and lower ends of the rotating rod through the screw and the nut. The rotating rod is fixed with the rod seat through the positioning screw and the positioning nut. The rod seat is provided with an upper connecting cavity and a lower connecting cavity. A self-locking through hole is arranged between the upper connecting cavity and the lower connecting cavity. One ends of the upper connecting cavity and the lower connecting cavity are respectively integrally provided with an upper movable groove and a lower movable groove. An upper locking rod and a lower locking rod are respectively arranged in the upper connecting cavity and the lower connecting cavity. Springs are sleeved outside the upper locking rod and the lower locking rod. A through hole one is arranged in the middle of the rotating rod and is designed to be opposite to the self-locking through hole in the middle of the rod seat.

[0006] Preferably, a lever is arranged between the two adjusting and self-locking devices. Both ends of the lever are inserted into the through hole I in the middle of the rotating rod and the self-locking through hole in the middle of the rod base.

The upper gear 31 is fixed on the adjusting plate 2, and the lower gear 32 is fixed on the bottom plate 1. The upper gear 31 and the lower gear 32 are designed to be offset. After folding, it is a flat structure. The upper gear 31 and the lower gear 32 are connected to the upper and lower ends of the rotating rod 35 through the screw 33 and the nut 34. The rotating rod 35 is fixed with a rod seat 38 through the positioning screw 36 and the positioning nut 37. The rod seat 38 is provided with an upper connection cavity 3801 and a lower connection cavity 3802. A self-locking through hole 3803 is arranged between the upper connection cavity 3801 and the lower connection cavity 3802. One ends of the upper connection cavity 3801 and the lower connection cavity 3802 are respectively integrally provided with an upper movable groove 3804 and a lower movable groove 3805. An upper locking rod 39 and a lower locking rod 310 are respectively arranged in the upper connection cavity 3801 and the lower connection cavity 3802. Springs 311 are sleeved outside the upper locking rod 39 and the lower locking rod 310. A first through hole 3501 is arranged in the middle of the rotating rod 35, and is designed to be opposite to the self-locking through hole 3803 in the middle of the rod seat 38.

[0019] There is a lever 4 arranged between two adjusting self-locking devices 3. The two ends of the lever 4 are inserted into the through hole 3501 in the middle of the rotating rod 35 and the self-locking through hole 3803 in the middle of the rod base 38. Open slots 41 and through holes 42 are arranged at both ends of the lever 4. A limiting screw 43 and a limiting screw 44 are respectively arranged in the through holes 42 at both ends of the lever 4. A self-locking spring 45 is arranged on the lever 4.
