Specific implementation manner
[0020] To make the above - mentioned features and advantages of the present utility model more understandable, specific embodiments are given below in conjunction with the accompanying drawings and described in detail as follows, but the present utility model is not limited thereto.
[0021] Reference Figures 1 to 4
[0022] A display mounting seat with a flipping limit - adjusting function includes a connecting seat plate 100 for connecting with the vertical arm of a bracket and a flipping seat 200 for connecting with a display board such as a display. A driving mechanism is provided between the connecting seat plate and the flipping seat to drive the flipping seat to flip up and down, realizing the automatic up - and - down flipping function of the flipping seat. A flipping - angle limit mechanism with an adjusting function is arranged on one side of the connecting seat plate to cooperate with the flipping seat, thereby limiting the flipping angle of the flipping seat and enabling fine - tuning of the flipping angle.
[0023] In this embodiment, the flipping - angle limit mechanism includes flipping limit switches 201 installed on the upper and lower sides of the rear part of the flipping seat. The flipping limit switches are electrically connected to the driving mechanism via a controller. On the upper and lower parts of one side end of the connecting seat plate, lugs 101 extending outwards are fixed, and adjusting bolts 102 are screwed on the lugs, and the adjusting bolts face the corresponding flipping limit switches. Thus, by rotating the adjusting bolts, the distance between the end of the adjusting bolt and the flipping limit switch is controlled to adjust the flipping angle.
[0024] In this embodiment, in order to realize the connection between the flipping seat and the connecting seat plate, wing plates 110 turning forward are arranged at both side ends of the connecting seat plate, and fixing plates 210 rotatably connected to the corresponding wing plates are fixed at both sides of the flipping seat.
[0025] In this embodiment, in order to hinge the wing plate on one side to the connecting plate and keep it in the corresponding position after being flipped to the required position, a transverse pin shaft 120 is passed through between the wing plate on one side and the fixed plate. The cross-section of the pin shaft is a waist-shaped structure formed by cutting off a bow-shaped structure from the upper and lower parts respectively. A baffle 121 is sleeved on the end of the transverse pin shaft passing through the fixed plate and locked by a nut 122. The baffle can move axially but cannot rotate. A sleeve is sleeved on the transverse pin shaft between the baffle and the fixed plate, and a torsion spring 123 is sleeved on the outside of the sleeve. One end of the torsion spring is connected to the fixed plate, and the other end of the torsion spring is connected to a card slot on the baffle.
[0026] In this embodiment, the driving mechanism is arranged between the wing plate on the other side and the fixed plate. Specifically, the driving mechanism includes a worm 203 vertically installed on the flipping seat and driven to rotate by a motor 202 through a reduction gear pair. A rotating shaft 130 is horizontally passed through between the wing plate on the other side and the fixed plate. A worm gear 140 meshing with the worm is installed on the rotating shaft. A pre-tightening component for fastening the worm gear is installed on the rotating shaft. The pre-tightening component makes the rotating shaft have a rotational damping between the wing plate and the fixed plate.
[0027] The pre-tightening component makes the worm gear drive the fixed plate and the flipping seat to flip through the pre-tightening force (clamping force). When the sum of the forces applied to the fixed plate is greater than the pre-tightening force (frictional force) between the fixed plate and the rotating shaft, the rotating shaft does not rotate and the connecting plate rotates. For example, when manually pushing the flipping seat, when the force applied to the flipping seat is not greater than 50 KN, the flipping seat can be rotated while the rotating shaft does not rotate. Or when the flipping of the flipping seat is blocked, the rotating shaft can rotate and the fixed plate does not rotate, avoiding damage to the motor and avoiding the situation of bumping people.
[0028] In this embodiment, the pre-tightening component includes a first disc spring 151 and a second disc spring 152. The arc openings of the first disc spring 151 and the second disc spring 152 face each other. A first disc spring is sleeved on one end of the rotating shaft passing through the fixed plate and a first locking nut 153 is screwed. A second disc spring is sleeved on one end of the rotating shaft passing through the wing plate and a second locking nut 154 is screwed. The worm gear is arranged between the second disc spring and the wing plate.
[0029] In this embodiment, a third gasket 155 is sleeved on the rotating shaft between the first disc spring and the outer end face of the fixed plate. The third gasket is in a stop connection with the fixed plate. A fourth gasket for stop connection with the wing plate is arranged on the rotating shaft between the worm gear and the wing plate.
[0030] In this embodiment, a first gasket 157 is provided between the wing plate and the fixing plate. On both sides of the first gasket, a fifth gasket 158 for stop connection with the fixing plate and a sixth gasket 159 for stop connection with the wing plate are provided. A second gasket 156 is provided between the second butterfly gasket and the second locking nut. A matching structure for driving the first gasket, the second gasket, the first butterfly gasket, the second butterfly gasket and the worm gear to rotate synchronously is provided on the rotating shaft. Thus, when the turbine rotates, the rotating shaft, the first gasket, the second gasket, the first butterfly gasket and the second butterfly gasket are driven to rotate simultaneously.
[0031] In this embodiment, the cross-section of the section of the rotating shaft located inside the fixture is circular, and the cross-sections of both ends of the rotating shaft passing through the fixing plate are non-circular. The first gasket, the second gasket, the first butterfly gasket, the second butterfly gasket and the worm gear are all provided with special-shaped holes matching the non-circular structure of the rotating shaft. For example, the cross-sections of the sections of the rotating shaft on both sides of the circular structure are waist-shaped structures formed by cutting off a bow-shaped structure from the upper and lower parts respectively, and the first gasket, the second gasket, the first butterfly gasket, the second butterfly gasket and the worm gear are respectively provided with waist-shaped holes matching the waist-shaped structure.
[0032] If terms such as "first" and "second" are used in the above text of the present utility model to limit components, those skilled in the art should be aware that: the use of "first" and "second" is only for the convenience of distinguishing components in description. Unless otherwise stated, the above terms have no special meaning.
[0033] If the present utility model discloses or involves components or structural members that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or it can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured by integral casting process) (except when it is obviously impossible to adopt the integral forming process).
[0034] In addition, unless otherwise stated, the terms used to represent the positional relationship or shape in any technical solution disclosed in the above present utility model include states or shapes similar, analogous or close to it.
[0035] Any component provided by the present utility model can either be assembled from a plurality of separate components or be a single component manufactured by an integral forming process.
[0036] The above are only the preferred embodiments of the present utility model. All equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
