Detailed Description

The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Embodiment one:

As shown in fig. 1-6, a chair back table comprising: the table body 100, the locking mechanism 300 and the unlocking block 400 which can be pressed, wherein the table body 100 is provided with a rotating shaft 200; the locking mechanism 300 comprises a fixing part 310, a rotating part 320 and a holding spring 330, wherein the rotating part 320 is rotatably connected with the fixing part 310, the rotating shaft 200 is fixedly connected with the rotating part 320 in the circumferential direction, the holding spring 330 is sleeved on the rotating part 320, one end of the holding spring 330 is connected with the fixing part 310, and the holding spring 330 holds the rotating part 320 tightly so as to limit the unidirectional rotation of the rotating shaft 200; the unlocking block 400 is connected to the other end of the clasping spring 330, and when the unlocking block 400 is pressed, the other end of the clasping spring 330 is pushed so that the clasping spring 330 releases the rotating member 320.

Locking mechanism 300 can lock pivot 200 to restrict the rotation of table body 100, thereby, in locking mechanism 300, hold tightly spring 330 and be in the internal diameter is less when normal state and hold rotating member 320, thereby hold tightly spring 330 and become big and rotate member 320 separation in the internal diameter when torsional deformation state, because hold tightly spring 330's one end and mounting 310 fixed connection and the other end is supported by unlocking block 400, when holding tightly spring 330 and holding rotating member 320's state, hold tightly spring 330 and can restrict rotating member 320 and rotate for mounting 310, thereby lock pivot 200 and with restriction table body 100 to turn over.

When unlocking, the unlocking block 400 is pressed, and the unlocking block 400 pushes the other end of the clasping spring 330, so that the clasping spring 330 is torsionally deformed and the rotating member 320 is released, and at this time, the table body 100 can be rotationally adjusted.

It should be noted that, the locking mechanism 300 is a one-way locking element, that is, in the locked state, the table body 100 may rotate in the retracting direction, but cannot rotate in the opening direction, because a certain friction exists between the rotating member 320 and the holding spring 330, when the table body 100 is opened, the rotating member 320 rotates in a direction that is just enough to tighten the holding spring 330; and when the table top body 100 is rotated in the retracting direction, the rotating member 320 is rotated in a direction that causes the clasping spring 330 to slightly twist and deform, so that the rotating member 320 is allowed to rotate in that direction.

In actual use, the table body 100 is in a unidirectional locked state, if the table body 100 needs to be adjusted, the angle of the table body 100 can be adjusted by pressing the unlocking block 400, and the rotating member 320 is held again by holding the spring 330 after the unlocking block 400 is released, so that the table body 100 is limited to be opened.
