Description

Rotary picture and text information display table

Technical Field

The utility model relates to a picture and text information display device technical field especially relates to a rotation type picture and text information display platform.

Background

At present, many exhibits need to be provided with graphic boards during exhibition so as to make necessary explanation or operation prompt for the exhibits. However, because there is the design defect, or be subject to the preparation material, technology etc, picture and text board in the exhibition hall is for the convenience of not equidirectional show at present, the structure that generally adopts can rotate, but the common fault that this kind of rotatory show structure exists at present is the life-span weak point, use a period and will go wrong, the leading cause is for practicing thrift the cost, directly drive the speed reducer with the motor, directly drive the carousel through the speed reducer and rotate, because the showpiece generally all has certain weight, so long-time can push down the output pole of speed reducer, because speed reducer itself does not set up the protection to the axial, so lead to using this output pole of a period and will take place to become flexible, finally lead to equipment damage, the later maintenance is very inconvenient, need to change whole speed reducer, the cost is also very high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a rotary type image-text information display platform.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a rotary type image-text information display table is characterized in that: comprises a bracket, a showing stand, a rotating shaft, a sleeve bracket, a sliding sleeve, a shell, a bottom plate, a right bevel gear, a lower bevel gear and a motor; the top of the sleeve support is fixed at the bottom of the support through a bolt, the sleeve support penetrates through the upper part of the shell and is in interference connection with the shell, the sliding sleeve is connected in the sleeve support in an interference manner, the rotating shaft penetrates through the sliding sleeve and is in running fit with the sliding sleeve, the upper part of the rotating shaft passes through the sleeve support and the support and is connected with the bottom of the upper display frame, the lower part of the rotating shaft is fixedly connected with the lower bevel gear, the lower part of the lower bevel gear is connected with the bottom plate through a thrust bearing and a rotating bearing, the bottom plate is fixed at the bottom of the shell through bolts, the lower bevel gear is meshed with the right bevel gear, the right bevel gear is fixed on a driving shaft, the driving shaft is connected with the side part of the shell through a bearing, and the other end of the driving shaft is connected with a motor fixed outside the shell.

Preferably, one side corresponding to the right bevel gear is provided with a left bevel gear, the left bevel gear is fixed on a left transmission shaft, and the left transmission shaft is installed on the left side of the shell through a bearing.

Preferably, the display rack is arranged on three sides, and the nut penetrates through the top of the display rack and is screwed on the rotating shaft.

Preferably, the number of the sliding sleeves is two, and the two sliding sleeves are respectively connected to the upper part and the lower part of the sleeve support in an interference manner.

Compared with the prior art, traditional speed reducer structure has been removed to this device, designs an solitary rotary mechanism, through the bevel gear transmission, can make the rotatory more stable of show stand, and the pivot adopts and utilizes sleeve support and sliding sleeve to carry out radial spacing, and the bottom is fixed with lower bevel gear, and lower bevel gear passes through thrust bearing and fixes with the bottom plate to the countershaft axial is carried out spacingly, and overall structure compactness very can improve holistic life greatly.

Detailed Description

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1, a rotary type image-text information display table comprises a support 1, a display frame 2, a rotating shaft 3, a sleeve support 4, a sliding sleeve 5, a shell 6, a bottom plate 7, a right bevel gear 8, a lower bevel gear 9 and a motor 10; the top of sleeve holder passes through the bolt fastening in the bottom of support, sleeve holder passes and rather than the interference connection from the upper portion of shell, directly impresses sleeve holder in the shell, in advance will sliding sleeve interference connection is in sleeve holder, specifically does, the sliding sleeve is two, and the difference interference connection is in sleeve holder's upper portion and lower part. The pivot is passed sliding sleeve and rather than normal running fit, the upper and lower both ends of pivot are direct and the sliding sleeve cooperation, and pivot surface and sliding sleeve inboard all very smooth, and the pivot can be directly at the internal rotation of sliding sleeve, the upper portion of pivot is passed sleeve holder and support are connected with the show shelf bottom on upper portion, the lower part of pivot with umbrella gear fixed connection down, down umbrella gear's lower part pass through thrust bearing 11 and rolling bearing 12 with the bottom plate is connected, be equivalent to down the fixed minor axis in umbrella gear bottom, installation rolling bearing between minor axis and the bottom plate, thrust bearing sets up at bottom plate and umbrella gear bottom self-checking down, and thrust bearing upwards supports lower umbrella gear. The bottom plate is fixed at the bottom of the shell through bolts, the lower bevel gear is meshed with the right bevel gear, the right bevel gear is fixed on a driving shaft 13, the driving shaft is connected with the side part of the shell through a bearing 14, and the other end of the driving shaft is connected with a motor fixed outside the shell.

In order to make the lower bevel gear symmetrical, not eccentric and improve the service life, a left bevel gear 15 is arranged on one side corresponding to the right bevel gear, the left bevel gear is fixed on a left transmission shaft 16, and the left transmission shaft is arranged on the left side of the shell through a bearing 17.

The utility model discloses in, the show shelf sets up and three side, and the nut passes and twists to the pivot from the top of show shelf.

The working principle is as follows: the motor rotates to drive the driving shaft to rotate, the driving shaft drives the bevel gear to rotate, so that the lower bevel gear is driven to rotate, the lower bevel gear drives the rotating shaft to rotate in the sliding sleeve, and therefore the display table on the upper portion is driven to rotate, and rotary display is achieved. The thrust bearing and bevel gear mechanism are used, so the device can bear a heavy upper display stand.

The device is very easy to assemble, the sliding sleeve is assembled firstly, then the bevel gears on the left and right sides are arranged, the bevel gear on the bottom is arranged on the bottom, finally the bottom plate is fixed on the shell through the bolt, and the bevel gear core is connected with the motor through the flange.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
