TWI248537B - Angle-adjusting supporting stand - Google Patents

Abstract

An angle-adjusting supporting stand comprises a panel carrier and a supporting plate, which are pivotally connected to a base. A vertical guide slot of the panel carrier cooperates with a slide movably disposed on the supporting plate. Two sides of the vertical guide slot are a rock and a control module respectively. The control module comprises locking element engaged with the rock, and a pull rod is connected with a side of the control module. When a user pulls the pull rod to drive the locking element moving away from the rack, the slide moves upwardly and downwardly along the vertical slot for adjusting the angle of supporting plate. The stand with lateral pull rod, the user can be controlled easily the pull rod regardless of sizes of display panels.

Description

1248537 V. INSTRUCTION DESCRIPTION α) Technical Field of the Invention The present invention relates to a support frame, and more particularly to a side pull type adjustable angle support frame. [Prior Art] The liquid crystal display device is widely used as a computer screen or a television. However, with the development of technology, a liquid crystal display device having a display function has been developed to have a touch or handwriting function, so that the user can directly point on the display device. Select function or handwriting input to provide a more convenient interface.

Referring to FIG. 1 , a conventional liquid crystal display device 10 is provided with a display panel 1 1 on a binding base 1 2 , and a pivot 1 1 1 and a nut which are sleeved with a disk-shaped spacer 1 3 2 . 1 3 3 locks, and the two ends of the joint seat 1 2 are pivotally connected to a support frame 13 3 , because the disc-shaped gasket 1 32 is pressed by the nut 331 , the rebound force thereof will support the support frame 13 and the joint 1 2 is in a tight state, and when the display panel 1 1 needs to be adjusted, it is necessary to position the joint 1 2 at the adjusted angle by pulling the panel 1 1; however, since the pivot 1 3 1 is easy to be long Wear and use will result in insufficient tension and positioning force, so that the support angle of the panel 1 1 will loosely slide; and the structure is easy to be subjected to force, that is, the angle of rotation, therefore, the operation required to apply pressure to the panel 1 (eg, handwriting) Or touch, the conventional structure obviously cannot support the force of the user's elbow while maintaining the angle.

Therefore, how to solve the problem that the conventional support frame has insufficient positioning force and can not bear the weight, so that the support frame can be applied to the handwriting or touch operation panel is to be researched and developed. [Summary of the Invention]

Description of the invention (5) Block 2 3 1 , the sliding block 2 3 1 is provided with a stud 2311 at a position corresponding to the vertical chute 2 2 3 , and the stud 2311 is placed in the chute 2 2 3 to guide The sliding block 2 3 1 moves along the vertical chute 2 2 3 , and the crest 2 3 1 1 has a c-shaped seat 2 3 2 with a horizontal chute 2 3 2 1 , and the clamping member 2 2 5 4 The utility model is disposed in the horizontal chute 2 3 2 1 of the c-shaped seat 2 3 2 , so that the clamping member 2 2 5 4 can be horizontally moved relative to the sliding block 2 3 1 ; Adjustable angle support frame 20 (as shown in Figure 2). Referring to FIGS. 4A and 4B, when a display panel (not shown) is mounted in front of the panel carrier 2 2 through the connecting hole 2 2 2, the horizontal leg 2 1 1 of the base 2 1 and the bottom of the panel are supported by On the table top (not shown), at this time, the polygonal body 2 2 5 3 3 is clamped in the inclined hole 2 2 5 1 4, and the reset element 2 2 5 5 slides the sliding plate 2 2 5 1 toward the rack 2 2 4 Pushing in the direction, so that the sliding plate 2 2 5 1 drives the clamping member 2 2 5 4 the tooth portion 2 2 5 4 1 is clamped to the rack 2 2 4 the latching tooth 2 24 1 so that the supporting frame 20 maintains a fixed angle (As shown in Figure 4A); again, as shown in Figure 4B, when the user pulls the lever 2 2 5 1 2 horizontally from the side of the panel, the inclined surface of the inclined hole 225 1 4 of the sliding plate 225 1 is linked. 2 2 5 14 1 pushes the polygonal body 225 33 , and makes the inclined hole 225 14 out of the polygonal body 2 2 5 3 3, at this time, pulls the pulling rod 2 2 5 1 2 to drive the sliding plate 2251 and through the horizontal guiding groove Guided by 22513, the sliding plate 2 2 5 1 is horizontally moved, and the hook member 225 4 which is hooked to the sliding plate 22 5 1 vertical guide groove 22 5 1 1 is taken off in parallel.

Page 10 V. Invention Description (6) The rack is 2 2 4, and the deformation is reduced. At this time, the support member 2 2 5 5 is squeezed and then the adjustable panel or panel is used to form an adjustable state. Straight chute 2 2 3 slides up and down 1 seat 2 2 so that the relative angle between the sliding block 2 3 3 = variable panel carrier 2 f 5% 512, at this time sliding ίί [? After r is set, it is: pushed by the elastic force of 5] 1 is pulled by the reset element 2 2 4 and the polygon body 2 = part 2 2 5 4 is stuck in | you, and the fixed support frame is stuck in Oblique hole 22 5ι, truss angle. 2〇 at the predetermined position, so as to achieve the use of the lever 2, and then slide the A f to control the adjustment angle of the support frame 2 ,, and the angle is adjusted by 2 force 1 sliding, so it can be fast 2 2 5 4 card in the rack 2 f teeth 2: use the card holder 2 2 and the support plate 2 3 1m: and the panel can be loaded around different angles of inclination, LV plant 4 pairs of positions to change, can provide panels Dafan is also used as a standard for panels for viewing or handwriting. On the back end of the panel, when the panel is used for large-size panels, if it is set to be raised, a Bourgeois rod, gauge, and lever position will increase with the panel size, and the panel will operate twice. When the user manipulates the lever, it is not easy to wrap around = 2 2 5 ], 9 and 2, which makes adjustment difficult. However, the present invention will pull 2 2 5 xp J from the side of the panel, and the user operates the lever: the board is enlarged ^ ί ΐ f Bypass the panel, and the length of the lever 2 2 5 1 2 can be lightly slid near the side of the panel, so any panel ruler can easily operate the lever 2 2 5 1 2 from the side of the panel instead of Will be 1248537 V. Invention description (7) Limited by the increase in panel size. Due to the use of the clamping member 2 2 5 4 tooth portion 2 2 5 4 1 and the rack 2 2 4 card tooth 2 2 4 1 mutual positioning, while using the inclined hole 2 2 5 1 4 and the polygonal body 2 25 3 3 The function of the clamping and resetting element 2 2 5 5 is to strengthen the locking ability of the supporting frame 20 in a fixed state, so as to force the clamping capability of the toothed portion 2 2 5 4 1 and the latching tooth 2 2 4 1 to be improved. Therefore, the support frame 20 can be more stably fixed. Therefore, when the user applies pressure to the panel by handwriting or touch operation, the support frame 20 can withstand the weight applied by the user without loosening. In addition, since the vertical guide groove 22 5 1 1 of the control group 25 and the horizontal guide groove 2 2 5 1 3 are designed, the driving clamp 2 2 5 4 is moved in a single direction, so that the clamping member 2 2 5 4 teeth The part 2 2 5 4 1 is separated from the rack 2 2 4 the latch 2 2 4 1 is clamped, so that the clip 2 2 5 4 can be smoothly separated from the card. The above description is only for the convenience of the description of the preferred embodiments of the present invention, and the scope of the present invention is not limited to the preferred embodiments, and any changes made in accordance with the present invention may be made without departing from the spirit of the present invention. It belongs to the scope of patent application of the present invention.
