Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be understood as imposing any limitation on the scope of the present invention.

As shown in fig. 1 to 7, the embodiment of the application provides a locking structure for adjusting any angle of a movable plate of a desktop, which can be used in scenes such as study tables, desks, dining tables, etc. The structure includes the following components:

a pair of fixing plates 1 connected to the lower surface of the table top movable plate 0, the pair of fixing plates 1 being vertically connected to the table top movable plate 0, the fixing plates 1 being formed with first passing holes 11.

Each angle adjusting plate 2 is partially overlapped with one fixing plate 1 and is connected with the fixing plate through a hinge 21, an arc-shaped groove 22 is formed in each angle adjusting plate 2, and the arc-shaped groove 22 takes the hinge 21 as the center of a circle.

And two ends of the cross shaft 3 sequentially penetrate through the arc-shaped groove 2 on the angle adjusting plate 2 and the first through 11 holes on the fixing plate 1 and extend out to two sides, one end of the cross shaft 3 is connected with an eccentric wrench 7, and the other end of the cross shaft 3 is connected with a locking piece 10.

The limiting transverse pipe 4 is sleeved outside the transverse shaft 3, and the limiting transverse pipe 4 is positioned between the pair of angle adjusting plates 2.

And the friction brake pads 5 are arranged between the two ends of the transverse limiting pipe 4 and the angle adjusting plate 2.

When the angle of the desktop movable plate 0 needs to be adjusted, the eccentric wrench 7 is loosened, the desktop movable plate 0 is pulled, and the transverse shaft 3 moves in the arc-shaped groove 2. When the adjusting device is adjusted to a proper position, the eccentric wrench 7 is locked, the eccentric wrench 7 and the locking piece 10 exert pressure inwards from two ends, the limiting transverse pipe 4 is relatively outwards propped against the friction brake pad 5, so that the friction brake pad 5 and the angle adjusting plate 2 generate friction force, and position locking is achieved. Compared with the existing angle adjusting structure, the structure provided by the embodiment can realize arbitrary angle adjustment (namely stepless adjustment) and ensure good stability.

In order to increase the stability of the locking, the cross section of the transverse shaft 3 can be designed to be non-circular, so that the transverse shaft 3 itself cannot rotate. For example, the cross-section of the transverse axis 3 may be rectangular, triangular, trapezoidal, parallelogram or elliptical. In the present embodiment, the cross-section of the transverse shaft 3 is square. In addition, the first through holes 11 of the fixing plate 1 may be formed in a slightly larger square shape corresponding to the cross-sectional shape of the lateral shaft 3, as shown in fig. 3, so that the rotation of the lateral shaft 3 and the eccentric handle 7 can be restricted.

In order to avoid the friction brake piece 5 and the angle adjusting plate 2 to separate and cause the locking to be invalid, a rotation stopping gasket 6 can be further arranged, a second through hole 61 is formed in the rotation stopping gasket 6, the transverse shaft 3 penetrates through the second through hole 61, the rotation stopping gasket 6 is arranged between the friction brake pad 5 and the limiting transverse pipe 4, and the rotation stopping gasket 6 is covered outside the friction brake pad 5 and is attached to the friction brake pad 5. Further, the second through hole 61 of the rotation stop washer 6 may be designed to be square in conformity with the square cross shaft 3, as shown in fig. 4, to prevent the rotation stop washer 6 and the friction brake washer 5 from rotating.

Referring to fig. 6 and 7, the eccentric wrench 7 is connected to the cross shaft 3 through a fixing shaft 71, the adjusting member 8 (which may be made of POM material) is sleeved on the end of the cross shaft 3, and the end of the eccentric wrench 7 and the fixing shaft 71 are clamped in the adjusting member 8 to ensure the position fixing.

In a possible embodiment, a padding sleeve 9 is sleeved on the transverse shaft 3, and the padding sleeve 9 is arranged between the fixing plate 1 and the adjusting piece 8.

Preferably, the surface of the friction brake pad 5 may be provided with an anti-slip texture, such as a rough leather texture, to increase the friction force and secure the locking force.

Furthermore, the locking element 10 can be designed as an adjusting nut which is screwed to the end of the transverse shaft 3, so that the locking force value of the eccentric wrench 7 can be controlled by means of the adjusting nut.

To sum up, the locking structure is adjusted to arbitrary angle of desktop fly leaf that this application embodiment provided realizes dying the mechanical lock of fly leaf through opening and shutting of eccentric spanner, can realize the position locking at arbitrary angle. Preferably, by adopting a square transverse shaft and performing corresponding design, the stability can be good.
