Detailed ways

Please refer to FIGS. 1 to 5 , which disclose a pivot device for a display screen, including a base 1 , a pressing member 2 , a connecting member 3 , a limiting mechanism 4 and a supporting member 5 .

The base 1 has a connection surface 11 and a linkage surface 12, the connection surface 11 is used for connecting a mounting plate 6 conforming to VESA standard, and the mounting plate 6 is used for installing a known display screen (not shown) . And the interlocking surface 12 is used for the installation of the pressing member 2, wherein the specific position of the interlocking surface 12 is on the bottom surface of the base 1, so the pressing member 2 is combined, for example, with a locking member, such as A screw passes through a bottom end of the pressing member 2 and is locked to the bottom surface of the base 1 .

The pressing part 2 is arranged on the bottom surface of the base 1, and a pressing part 21 extends on one side. The pressing part 2 has a pair of adjacent flat surfaces 24 and a pair of inclined surfaces 22 on the pressing part 21. The pair of flat surfaces 24 is formed by extending horizontally away from the side of the base 1, so that the pair of planes 24 of the pressing part 21 are located on the opposite side of the connection position between the pressing part 2 and the base 1. As for the The pair of slopes 22 continues to extend away from the side of the base 1 and obliquely from the side of the pair of planes 24, as shown in Figures 1 and 2, the pressing part 21 is a pair of supporting arms arranged at intervals, The pair of support arms each have the pair of planes 24 and the pair of slopes 22, so that the pair of planes 24 and the pair of slopes 22 of the pressing portion 21 are respectively in contact with an abutting portion 431 of the position-limiting mechanism 4 in the assembled state. touch.

In another embodiment, the base 1 and the pressing member 2 are integrally formed, and the locking process using the locking member, such as a screw, can be omitted. In the integrally formed structure, the pressing portion 21 The adjacent pair of flat surfaces 24 and the pair of inclined surfaces 22 are still in contact with the abutting portion 431 .

The connector 3 is an inverted U-shaped frame, one side of which is pivotally connected to the base 1 by a pivot 31, and a pivot space 32 for the rotation of the base 1 is opened, so that the base 1 is accommodated and pivoted. in the connector 3. On the other side of the connecting member 3 , there is an accommodating space 33 corresponding to the position of the base 1 and the pressing member 2 for the moving of the pressing member 2 , thereby forming the effect of shielding and protection.

The limiting mechanism 4 is arranged between the pressing member 2 and the connecting member 3, wherein the limiting mechanism 4 includes a fixing member 41, an elastic member 42, a movable bushing 43, and an adjusting member 44. The fixing part 41 is fixed on the top surface of the connecting part 3 , for example, a joint part 412 , such as a screw, passes through the top surface of the connecting part 3 and is screwed to a head 411 at one end of the fixing part 41 . The fixing member 41 is sequentially sleeved with the elastic member 42 in the accommodation space 33 , such as a spring, and then passes through the movable bush 43 , so that the elastic member 42 is sandwiched between the connecting member 3 and the movable bush 43 between, and let an abutting portion 431 at the bottom of the movable bushing 43 touch the pressing portion 21 of the pressing member 2, after an engaging section 413 at the other end of the fixing member 41 passes through the movable bushing 43, That is, it is combined with the adjustment member 44 , for example screwed. And the pressing member 2 can be a U-shaped frame body and a hollow groove 23 is opened corresponding to the position of the fixing member 41 and the adjusting member 44 on the moving path, so that the hollow groove 23 is formed on the pressing The pressing part 21 of the piece 2, let the pressing part 21 become a pair of plate-shaped support arms arranged at intervals, which helps to reduce the thickness and volume, and makes the pressing part 21 still provide support in the longitudinal direction, and also The hollow groove 23 is located between the pair of plate-shaped support arms, so that the base 1 and the pressing member 2 will not interfere with the fixing member 41 and the adjusting member 44 during rotation.

Therefore, through the longitudinal adjustment and positioning of the adjusting member 44 on the joint section 413 of the fixing member 41 , the longitudinal movable space of the movable bush 43 is limited.

One end of the support member 5 is connected in the accommodating space 33 at the opposite end of the pivot space 32 of the connecting member 3, and the other end of the support member 5 is connected in a known base ( not shown).

Fig. 1 shows a perspective view of the assembled pivot device of the present invention, the assembly plate 6 can be further connected with a display screen (known, not shown). As shown in FIG. 4, when the user wants to adjust the display screen, for example, adjust the depression angle of the display screen, the part of the base 1 located in the pivot space 32 will rotate counterclockwise, so that the base 1 and the pressing The position where the component 2 is connected will move downward, and the pair of flat surfaces 24 of the pressing portion 21 will be moved away from the abutting portion 431, and the adjacent pair of inclined surfaces 22 will move upward toward a first direction X to touch and push Squeeze the abutting portion 431 of the movable bush 43 to gradually compress the elastic member 42, so that the elastic member 42 is limited between the connecting member 3 and the movable bush 43, and the elastic member 42 forms a reservoir It can be used to resist the forward tilting moment of the display screen, thereby forming a supporting effect.

The lower part of the fixing member 41 and the adjusting member 44 pass through the bottom of the hollow groove 23 . The advantage is that the length of the fixing member 41 can be increased, thereby effectively providing adjustment and limiting the movable space of the movable bush 43 .

Conversely, as shown in FIG. 5 , when the user adjusts the elevation angle of the display screen, the part of the base 1 located in the pivot space 32 will rotate clockwise, so that the base 1 and the pressing member 2 are connected. will move upwards, and the pair of slopes 22 of the pressing portion 21 will be moved down toward a second direction Y to leave the abutting portion 431, and the pair of adjacent flat surfaces 24 will continue to touch the abutting portion 431. During this process, the compressed elastic member 42 is gradually released to stretch the elastic member 42, and push the abutting portion 431 of the movable bushing 43 against the pair of flat surfaces 24 of the pressing portion 21 and the adjusting member 44, The elastic member 42 is continuously limited between the connecting member 3 and the movable bushing 43 . And the base 1 will form a stop function with the contact surface of one side end of the connecting member 3 at the position where the connecting surface 11 is located, so as to avoid the situation that the elevation angle is too large.

Furthermore, the connecting surface 11 of the base 1 and the adjoining surface of the mounting plate 6 are provided with a known pivot device 7 in addition, and its rotation centerline is perpendicular to the rotation centerline of the pivot shaft 31, so that the pivot The rotation device 7 provides the rotation adjustment function of the left and right rotation of the mounting plate 6 .

Therefore, through the implementation of the present invention, the enhanced effect is that when the display screen is adjusted for pitch angle, the base will pivot accordingly, and drive the resisting member to move upward or downward, so that the resisting The pressing part will drive the movable bush to compress or release the elastic part, so as to adjust the pitch angle and support the display screen. It is a great structure that has never been seen before in similar products.
