Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

as shown in fig. 1-3, a table side-turning structure comprises a support frame 1 and a support rod 2, wherein the support rod 2 is rotatably connected to the support frame 1, a table 3 is fixed to the support rod 2, and a plurality of locking holes 51 corresponding to each other are formed in the support rod 2 and the support frame 1; the support rod 2 is also provided with a lock pin 4 matched with the lock hole 51.

The working principle of the scheme is as follows: through the rotation of control bracing piece 2, reach the effect of control table 3 angles, lockpin 4 and lockhole 51's cooperation is simple, convenient operation. As shown in fig. 4-7, a locking block 6 is fixed on the support rod 2, a lock disc 5 is arranged on the support frame 1, and a plurality of lock holes 51 are arranged on the lock disc 5; one end of the lock pin 4 penetrates through the lock block 6 to be matched with the lock hole 51, the other end of the lock pin 4 is provided with a pull head 41, an extension spring is further sleeved outside the lock pin 4, and two ends of the extension spring are respectively fixed on the pull head 41 and the lock block 6. The lock pin 4 is elastically connected to one side of the support rod 2 along the axial direction of the support rod 2. The lock pin 4 is pulled by the pull head 41 and then automatically rebounds when locking is required, so that the control is convenient, and the lock pin 4 is connected with the support rod 2 and cannot fall off. Of course, it is also possible to arrange the locking pin 4 on the support 1 and the locking disk 5 on the support. The resilient connection of the locking pin 4 can be provided simply without the slider 41, the slider 41 being provided for easier handling. The lock disc 5 is fan-shaped, the two sides of the lock disc 5 are provided with side baffles 52, and the lock block 6 is provided with a convex block 61 which is matched with the side baffles 52 and used for limiting the rotation angle of the support rod 2. A plurality of lock holes 51 are arranged on an arc taking the axial direction of the support rod 2 as the center in the sector area, so that the lock pin 4 can be matched with the lock holes 51 at corresponding positions at a plurality of angles in the sector area. Of course, a 360 ° ring-shaped lock disc 5 can be provided, but generally speaking, the table board 3 only needs to be turned over at a small angle, and is not comfortable to look up when lying down completely, and the side stop 52 can be provided to prevent the table board from turning over. When the lock pin 4 is matched with the lock hole 51 at the edge of the lock disc 5, the side stop 52 is close to or contacted with the lug 61 to limit the support rod 2. The locking pin 4 is not limited to be matched with all the locking holes 51, and the table plate 3 is prevented from rotating over the head. The end of the lock pin 4 is provided with a guide surface, and the guide surface can be a whole circular arc surface or a certain taper. When the insertion is started, the area of the corresponding lock hole 51 is small, and after the insertion is completed gradually, the lock hole 51 is completely matched with the lock pin 4, so that the effects of convenient insertion and stability after the insertion are achieved.

The support rod 2 is provided with a plurality of auxiliary supports 21 at the bottom of the table plate 3 along the width direction of the table plate 3. The auxiliary support 21 allows the table 3 to be more stably fixed. The edge of the table plate 3 is provided with a barrier strip 31, and the barrier strip 31 is parallel to the support rod 2. The barrier strip 31 can facilitate the placement of books or electronic equipment when reading books or videos, but is not suitable to be arranged higher than the table plate 3 too much to affect dining.

According to the above technical scheme, the utility model discloses a working process does: when the dining table is used, the table plate 3 is unfolded to be parallel to the horizontal plane, and the lock pin 4 is matched with the lock hole 51 in the middle of the lock disc 5; when reading books or reading electronic products, the lock pin 4 is withdrawn from the lock hole 51 of the lock disc 5 through the pull head 41, and is adjusted towards two sides, so that the desk board 3 can be used on different sides of the bed. After the proper angle is adjusted, the position of the lock hole 51 is approximately corresponding to the attention; when the slider 41 is loosened, the guiding part of the lock pin 4 is firstly matched with the lock hole 51, then the table plate 3 is slightly rotated along the matching direction, and the lock pin 4 is completely matched with the lock hole 51 and is fixed stably.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
