Description
Technical Field
The utility model relates to a design teaching in the teaching appurtenance is with data show shelf.
Background
In design class teaching field, the teacher can use the show shelf to place the teaching material (like the teaching plan) when giving lessons to the student, present show shelf is like "an industrial design teaching material show shelf" that chinese patent CN209825633U discloses, the dust cover including hollow structure, the bottom of dust cover is provided with the base, the upper end of dust cover articulates there is the backup pad, the inside screw rod that is equipped with vertical layout that rotates of dust cover, the transmission is connected with the screw on the screw rod, be connected through the push rod between the upper end of backup pad and the screw, the upper end of push rod links to each other with the backup pad is articulated, the lower extreme of push rod links to each other with the screw is articulated, the coaxial line is fixed with first bevel gear on the screw rod, it is equipped with the pivot of arranging perpendicularly in the screw rod to rotate on the dust cover, be.
During the use, the mr places the teaching material in the backup pad, because different mr's height is different, therefore mr needs the angle of adjustment backup pad to adapt to mr's height, and during the adjustment backup pad angle, mr drives the pivot through revolving first bevel gear soon, and first bevel gear drives the pivot through the second bevel gear and rotates, thereby the pivot drives the screw and reciprocates the angle that realizes the adjustment backup pad. The problems of the prior display rack are that: the supporting plate angle adjustment is realized through the transmission between first bevel gear, second bevel gear, pivot and the screw, and is harder, and every turn of pivot rotates the round in addition, and screw pitch that the screw could walk, and the adjustment efficiency is low very much, and more importantly needs to set up pivot and screw in the dust cover is inside for the dust cover needs great size just can satisfy the requirement, makes whole show shelf seem comparatively heavy.
Disclosure of Invention
An object of the utility model is to provide a design data show shelf for teaching to adjust the backup pad angle through pivot, screw among the solution prior art and lead to the lower technical problem of backup pad angular adjustment efficiency.
In order to solve the technical problem, the technical scheme of the utility model as follows:
the design teaching data display rack comprises a supporting rod, wherein a supporting plate is hinged to the upper end of the supporting rod, a guide long groove extending in the vertical direction is formed in the supporting rod, the guide long groove penetrates through the supporting rod in the left-right direction, an adjusting screw rod used for moving up and down along the guide long groove penetrates through the guide long groove, adjusting nuts are screwed on the adjusting screw rod on the left side and the right side of the supporting rod, opposite side faces of the two adjusting nuts are used for being tightly matched with the supporting rod in a propping mode, the upper end of the supporting rod is connected with one end of the adjusting screw rod through a connecting rod, the upper end of the connecting rod is hinged.
The supporting rod comprises an upper supporting rod part and a lower supporting rod part, the upper supporting rod part is in threaded connection with the lower supporting rod part, and the guide long groove and the supporting plate are arranged on the upper supporting rod part.
The upper end of the lower side supporting rod part is provided with a vertically arranged threaded hole, and the upper side supporting rod part comprises a screw rod matched with the threaded hole.
The upper end of the lower side supporting rod part is fixed with a limiting sleeve, a screw rod baffle is fixed on the screw rod, an inward-turning edge used for being matched with the screw rod baffle in a blocking mode to limit the upward movement limit of the screw rod is arranged at the inward-turning position of the upper end of the limiting sleeve, and a threaded hole opening edge used for being matched with the screw rod baffle in a blocking mode to limit the downward movement limit of the screw rod is formed in the threaded hole.
The utility model has the advantages that: the utility model discloses in, when needing the adjustment backup pad angle, loosen the adjusting nut of one side, the direct backup pad that overturns, the connecting rod drives adjusting screw and reciprocates in the direction elongated slot and can realize the adjustment of backup pad angle, and the adjustment back that targets in place only needs locking adjusting nut can, that is to say this is novel in, does not need the screw thread transmission to realize the backup pad angle, can realize the adjustment of backup pad angle fast.

Detailed Description
An embodiment of a design teaching material display rack is shown in fig. 1 to 3: including branch 10, the bottom of branch 10 is fixed with base 5, and the top of branch 10 articulates there is backup pad 1, and branch includes upside branch part 6 and downside branch part 4, and the upper end of downside branch part 4 is provided with vertical arrangement's screw hole 14, and upside branch part 6 includes with screw hole complex screw rod 13. The upper end of the lower side support rod part 4 is fixed with a limiting sleeve 12, a screw rod baffle plate 3 is fixed on the screw rod, an inward-turning edge 11 which is used for being in stop fit with the screw rod baffle plate to limit the upward movement limit of the screw rod is arranged at the inward-turning of the upper end of the limiting sleeve 12, and a threaded hole edge 15 which is used for being in stop fit with the screw rod baffle plate 3 to limit the downward movement limit of the screw rod is arranged in the threaded hole 14.
The upper side support rod part 6 is provided with a guide long groove 7 extending along the vertical direction, the guide long groove penetrates through the support rod along the left-right direction, an adjusting screw rod 9 used for moving up and down along the guide long groove is arranged in the guide long groove 7 in a penetrating mode, adjusting nuts 8 are connected to the left side and the right side of the support rod on the adjusting screw rod 9 in a threaded mode, opposite side faces of the two adjusting nuts 8 are used for being tightly matched with the support rod in a propping mode, the upper end of the support rod is connected with one end of the adjusting screw rod through a connecting rod 2, the upper end of the connecting rod 2 is hinged to the.
When the height of the supporting plate is adjusted to the maximum position, if the height of the supporting plate is adjusted to the maximum position, the supporting plate does not face a teacher, the teacher can lift the supporting rod, and the supporting rod is integrally rotated to adjust the facing angle of the supporting plate. When the pitch angle of the supporting plate needs to be adjusted, the operator only needs to loosen the adjusting nut on one side and loosen one or two circles, the operator directly holds the supporting plate to turn over the supporting plate, the connecting rod drives the adjusting screw rod to move up and down in the guide long groove, and after the pitch angle of the supporting plate is adjusted in place, the adjusting nut is locked to fix the position of the supporting plate.
