Detailed Description
A locking and movable arm mechanism of a display bracket comprises a slide rail locking structure connection for locking a slide rail, wherein the slide rail is connected with a movable arm mechanism connected with a display fixing plate; the sliding rail locking structure is connected with the base through a vertical rod;
the base is in an upper locking base form and comprises a base casting 1, a base movable sheet 2, a base movable clamping plate 3 and a screw 4, wherein the base movable sheet and the base movable clamping plate are fixed through a threaded column, the lower end of the base casting is provided with a limiting groove for moving the base movable sheet (the width of the limiting groove is matched with the thickness of the base movable sheet so as to ensure that the base movable sheet 2 does not have displacement in the horizontal direction and ensure the stability of the bracket base to a certain extent), the upper end of the base movable sheet is provided with a through long threaded groove, and when the base movable sheet is installed in the limiting groove of the base casting, the screw 4 moves in the threaded groove on the base movable sheet to drive the base movable sheet to move up and down and realize locking and fixing installation between the base and the table plate; the top of the vertical rod is provided with a rotary joint which can be selected by 360 degrees.
The slide rail locking structure is a two-piece locking structure and comprises a base hoop connector 5 connected with the vertical rod, a base movable hoop sheet 6 and a slide rail 7; the base hoop connector and the base casting form an inclined angle, the slide rail is placed between the base hoop connector and the base movable hoop sheet to slide back and forth, and the screw 8 penetrates through the threaded holes of the base hoop connector and the base movable hoop sheet and is tightened and loosened through threads, so that the slide rail can slide back and forth and be fixed; the base hoop connector and the base casting form an inclination angle of 25 degrees.
The slide rail locking structure has the advantages that:
(1) the sliding rail 7 which slides back and forth has the advantages of convenience, rapidness and directness when the display moves.
(2) When the specific angle of 25 degrees is adopted, the human engineering design in use is met.
The movable arm mechanism comprises a ratchet wheel joint 9, a joint 12, a lower movable arm 13 and an upper movable arm 15, and the ratchet wheel joint, the joint, the lower movable arm and the upper movable arm are connected and installed through a pin shaft to form a parallel four-bar linkage; the lower movable arm is provided with a pressing mechanism for pressing down the pawl button 10, and the front end of the pawl button is inserted into a tooth groove of the ratchet joint. The movable arm adopting the ratchet structure thoroughly solves the weight limit of the display under the condition of theoretically allowing the strength of parts. The pressing mechanism comprises a spring gland 14 which is in contact with a pressure spring 11, and the pressure spring presses on the pawl button. The detent button is in the form of a lever.
Initial state: when the joint 12 is subjected to a downward acting force due to the display mounted (or the self weight of the joint 12). Under the action of the spring gland 14 and the pressure spring 11, the pawl button 10 is inserted into the tooth groove of the ratchet joint 9 to play a limiting role. This achieves hovering of the joint 12.
An upward adjustment process: when the joint knuckle 12 is to be raised (i.e., the display is raised), the pawl button 10 will be pulled out of the gullet of the ratchet knuckle 9 by applying only an upward lifting force. When the proper position is reached, the force is only required to be withdrawn directly, and when the joint 12 is subjected to a downward force due to the mounted display (or the self weight of the joint 12). The pawl button 10 is inserted into the tooth grooves of the ratchet joint 9 under the action of the spring gland 14 and the pressure spring 11 to play a limiting role. This achieves hovering of the joint 12.
The following adjustment process: when the joint 12 is to be lowered (i.e., the monitor is lowered), the joint 12 is held (i.e., the monitor is held), and the pawl button 10 is pressed and withdrawn from the tooth space of the ratchet joint 9. When lowered to the proper height, the detent button 10 is released and the supported joint 12 (i.e., the supported display) is slowly released, whereupon the joint 12 is forced downward. Under the action of the spring gland 14 and the pressure spring 11, the pawl button 10 is inserted into the tooth groove of the ratchet joint 9 again to play a limiting role. This enables the joint 12 to be hovered again.
