Abstract

The utility model discloses a height adjustable tablet chair for a student. The tablet chair is characterized in that nuts supported by a tablet chair rack are arranged below the tablet chair; screws matched with taps are arranged in nut holes; steps are arranged below the upward ends of the screws, support rigid supports and can rotate relative to the rigid supports; the upward ends of the screws are provided with fixing pieces; wrench joints are formed at joints of the upward ends of the screws and the fixing pieces or at the lower ends of the screws; a chair panel is arranged above the rigid supports, and guide posts are arranged below the rigid supports; guide holes are formed on the tablet chair rack; and extrusion head screws are arranged between the guide holes and the guide posts. When the wrench joints are formed at the upper ends of the screws, holes are formed at the upper ends of the screws corresponding to the chair panel. The tablet chair is driven by the screws, the rigid supports are pushed to drive the table surface to lift, the height of the seat surface is adjusted, and the problem that the conventional table chairs for children and youngsters are not suitable can be completely solved; and moreover, the height adjustable tablet chair is simple and firm in structure, low in manufacturing cost and convenient to popularize.

Description

Height Adjustable student uses tablet chair

Technical field

The utility model relates to tablet chair, is about the invention of Height Adjustable student with tablet chair.

Background technology

The student is uncontrollable with tablet chair seat surface height at present; Student's height is constantly being grown tall in fact, they need most desk tablet chair height and height adaptive, use can be regulated the tablet chair of tablet chair seat surface height; Although being arranged in the commodity, a lot of hydraulic pressure or spring regulate the swivel chair of seat height; But this seat is easy to damage, and is unfavorable for that again the student sits up straight, so in the student, be difficult to promote the use of.

Summary of the invention

The purpose of the utility model is to provide a kind of Height Adjustable student of screw drive to use tablet chair.

The purpose of the utility model is achieved in that the nut that under tablet chair, is provided with by the supporting of tablet chair frame, establishes the screw rod that cooperates with its tooth in the nut bore, and the termination that screw rod makes progress divides into step; The holder of step rigidity of support, and can be pop-jump moving with respect to rigidity, fixture is established in the termination that screw rod makes progress; Prevent rigidity holder slippage from the screw rod, fixture and screw rod can be welded to connect, screw rod upper end and fixture junction or establish the spanner interface at the screw rod lower end; Through the spanner drive screw turns, the holder of ejection rigidity is gone up and down, and establishes the seat plate above the rigidity holder; Establish lead below, on the tablet chair frame, establish pilot hole, pilot hole can be in the tablet chair leg; Between pilot hole and lead, can establish crowded head screw, on the chair frame, rock to prevent the seat plate.When the spanner interface is located at the screw rod upper end, in the corresponding screw rod upper end position perforate of seat plate, cooperates so that spanner stretches into from the hole with the spanner interface, the seat plate in screw rod upper end position tapping should establish the gadget covering.Can express installing desk tablet chair height and the adaptive scale of height on the facade of height at tablet chair, adaptive scale zero graduation and desk desktop are maintained an equal level, the standard seat of clearly indicating the student of the different heights of this desk of use to have is high.

The Height Adjustable student of the utility model uses tablet chair, uses screw drive, and the ejection rigidity is entrusted moving seat up-down, regulates the seat surface height, can solve present child, the not adaptive problem of teen-age tablet chair fully.And simple in structure firm, low cost of manufacture is convenient to popularize.

Description of drawings

Fig. 1 is that Height Adjustable student uses the tablet chair structural representation.

Fig. 2 is the structural representation of gadget.

The specific embodiment

With reference to Fig. 1, Fig. 2, the nut 12 by 13 supportings of tablet chair frame is set under tablet chair, establish the screw rod 14 that cooperates with its tooth in nut 12 holes; The termination that screw rod 14 makes progress divides into step 5, step 5 rigidity of support holders 6, and can rotate with respect to rigidity holder 6; Fixture 4 is established in the termination that screw rod 14 makes progress, and prevents rigidity holder 6 slippage from the screw rod 14, and fixture 4 can be welded to connect with screw rod 14; Rotate through spanner drive screw 14 screw rod 14 upper ends and fixture 4 junctions or establish spanner interface 5 at screw rod 14 lower ends, and ejection rigidity holder 6 is gone up and down; Establish seat plate 7 above the rigidity holder 6, establish lead 9 below, on tablet chair frame 13, establish pilot hole 8; Pilot hole 8 can be established between pilot hole 8 and lead 9 and squeeze head screw 16 in tablet chair leg 10, rocks on chair frame 13 to prevent seat plate 7.When spanner interface 5 is located at screw rod 14 upper ends; Screw rod 14 upper end position perforates 11 in seat plate 7 correspondences; So that stretching into from hole 11 with spanner interface 5, spanner cooperates; Seat plate 7 should be established gadget 15 at screw rod 14 upper end position tappings and hide, and can express installing desk tablet chair height and the adaptive scale 2 of height on the facade 1 of height at tablet chair, and the standard seat of clearly indicating the student of the different heights of this tablet chair of use to have is high.

Claims
