Abstract

The utility model discloses a school table having adjustable table top angles. The school table comprises two table legs and a panel placed on the upper surfaces of the table legs, a supporting surface connected with the table legs is arranged below the panel, the rear end of the upper portion of the supporting surface is hinged with the panel, and a panel angle adjusting part is connected between the panel and the supporting surface. The panel angle adjusting part comprises an outer sliding sleeve and an inner sliding rod which is arranged inside the outer sliding sleeve in a sliding mode, the inner sliding rod is provided with a clamp part containing cavity, and a clamp port is formed on one side of the clamp part containing cavity. A clamp part is arranged inside the clamp part containing cavity, one end of the clamp part is limited inside the clamp port, the clamp part is provided with a clamp rod, locating clamp ports are arranged on two sides of the outer sliding sleeve, and a clamp part spring is arranged between the middle of the clamp part and the clamp part containing cavity. When the school table is used, the panel is only pulled to an appropriate angle along the hinging portion, if the panel needs restoring to a horizontal state, the panel is pulled to the position of the maximal angle and then is directly pulled back to the horizontal position, operation is greatly convenient and can be completed in a bare-handed mode, any other auxiliary tools are not needed.

Description

The desk that a kind of tabletop angles is adjustable

Technical field

The utility model belongs to a tool technical field, is specifically related to the adjustable desk of a kind of tabletop angles.

Background technology

The desk that the students in middle and primary schools of prior art use has and much all is designed to height-adjustable, can adapt to better like this height of adjusting easily desk after adolescent student height increases, also the student writes some desk, difference needs when reading in order to make things convenient for, desktop is set to tilt, it generally is the gradient of regulating desktop by stay bolt is set, because the pitch of bolt is generally less, needs the long period rotating bolt to regulate during adjusting, also has inconvenience during practical operation.

Summary of the invention

The purpose of this utility model is: the deficiency for prior art exists provides a kind of Stability Analysis of Structures, the desk that tabletop angles is easy to adjust.

For realizing the purpose of the utility model, be achieved by the following technical solutions: the desk that a kind of tabletop angles is adjustable, the panel that includes two table legs and be positioned at the table leg top, the panel below is provided with the supporting surface that is connected with table leg, supporting surface rear end, top and panel hinged also are connected with a panel angle adjusting piece between panel and the supporting surface.Described panel angle regulating part includes outer sliding sleeve and is slidingly arranged in the interior interior slide bar of outer sliding sleeve, and interior slide bar end and supporting surface are hinged, outer sliding sleeve end and panel lower hinge; Be provided with the fastener cavity volume on the described interior slide bar, fastener cavity volume one side is provided with bayonet socket, in the fastener cavity volume fastener is installed, the dop of fastener one end is limited in the bayonet socket, be provided with perpendicular kelly on the fastener, the outer sliding sleeve both sides are provided with the limited bayonet for the unidirectional fastening of kelly, also are provided with the push card masthead to the fastener spring of limited bayonet between fastener middle part and the fastener cavity volume.

As preferred version: interior slide bar one side in the described outer sliding sleeve is provided with back the cunning locating part, interior slide bar sidewall is provided with and carries out spacing spacing preiection and limiting block end to returning sliding locating part, returns to be provided with on the sliding locating part and limit the limited mouth that kelly breaks away from limited bayonet in the relative outer sliding sleeve return motion of interior slide bar.

Compared with prior art, the beneficial effects of the utility model are: owing to adjust the angle of panel with the panel angle regulating part, only needing that panel is pulled to proper angle along hinge point gets final product, make panel Reversion Level state, then panel is pulled to the maximum angle position, then can directly pushes back to horizontal level, easy to operate, the free-hand complete operation that gets final product need not other any aid.

The specific embodiment

The below makes a detailed explanation the specific embodiment of the present utility model with reference to the accompanying drawings.

Embodiment

Extremely shown in Figure 6 according to Fig. 1, the adjustable desk of the described a kind of tabletop angles of present embodiment, the panel 5 that includes two table legs 1 and be positioned at table leg 1 top, panel 5 belows are provided with the supporting surface 8 that is connected with table leg 1, supporting surface rear end, 8 top and panel 5 are hinged, also are connected with a panel angle adjusting piece 7 between panel 5 and the supporting surface 8.Described panel angle regulating part 7 includes outer sliding sleeve 72 and the interior slide bar 71 that is slidingly arranged in the outer sliding sleeve 72, and interior slide bar 71 ends and supporting surface 8 are hinged, outer sliding sleeve 72 ends and panel 5 lower hinge; Be provided with fastener cavity volume 711 on the described interior slide bar 71, fastener cavity volume 711 1 sides are provided with bayonet socket 712, fastener 74 is installed in the fastener cavity volume 711, the dop 742 of fastener 74 1 ends is limited in the bayonet socket 712, be provided with perpendicular kelly 741 on the fastener 74, outer sliding sleeve 72 both sides are provided with the limited bayonet 721 for kelly 741 unidirectional fastenings, also are provided with between fastener 74 middle parts and the fastener cavity volume 711 to promote kelly 741 tops to the fastener spring 75 of limited bayonet 721.

Interior slide bar 71 1 sides in the described outer sliding sleeve 72 are provided with back sliding locating part 73, interior slide bar 71 sidewalls are provided with and carry out spacing spacing preiection 713 and limiting block end 714 to returning sliding locating part 73, return to be provided with on the sliding locating part 73 and limit the limited mouth 731 that kelly 741 breaks away from limited bayonet 721 in interior slide bar 71 relative outer sliding sleeve 72 return motions.

When needs arrange panel 5 and are in heeling condition, namely when interior slide bar 71 relative outer sliding sleeve 72 reverse displacement, kelly 741 on the fastener 74 can slide along limited bayonet 721, when reaching desired location, hand unclamps panel 5, and panel 5 rotates towards supporting surface 8 directions under Action of Gravity Field, interior slide bar 71 and outer sliding sleeve 72 move toward one another, kelly 741 snaps in the limited bayonet 721 of relevant position, realizes the purpose of support panel 5.When needs return back to horizontal level with panel 5, first panel is continued to be pulled upwardly, make interior slide bar 71 and outer sliding sleeve 72 continue oppositely to be moved to extreme position, this moment, kelly 741 snapped in the limited mouth 731 of replying locating part 73, then pressed down panel 5 and can make it to return back to horizontal level.In this process, kelly 741 is limited in the limited mouth 731 and breaks away from limited bayonet 721, can not be subject to it to stop, behind the pull-up panel 5, kelly 741 breaks away from limited mouths 731 again.The distance that described spacing preiection 713 and limiting block end are 714 deducts back the length of sliding locating part 73 greater than the length of limited mouth, thereby guarantees that kelly 741 can break away from limited mouth 731.

Be arranged with adjusting rod 3 on the described table leg 1, table leg 1 is connected with supporting surface 8 by adjusting rod 3, be provided with a plurality of hole clippings on the adjusting rod 3, table leg 1 is connected by holding out against knob 2 with adjusting rod 3, hold out against knob 2 and be threaded with table leg 1, hold out against knob 2 ends and be connected with the hole clipping fastening of adjusting rod 3 relevant positions.
