Abstract

The utility model relates to a folding desk, which mainly comprises a desktop, positioning seats, foot tubes, oblique bracing tubes, end sleeves, telescopic bracing tubes, hinged seats, extension tubes, a landing tube, foot sleeves, elastic balls, transverse bracing tubes and adapters, and is characterized in that the positioning seats are arranged on a desktop board, and the foot tubes and the oblique bracing tubes are arranged in the positioning seats; the elastic balls are arranged on the foot tubes, and the foot tubes are placed in the extension tubes; the extension tubes are fixedly arranged on the adaptors and are provided with the hinged seats, and the end sleeves are arranged on the oblique bracing tubes; and one end of each telescopic tube is provided with the elastic balls and placed in the oblique bracing tube, and the other end of each telescopic tube is hinged with the hinged seat. The desktop, the foot tubes, the oblique bracing tubes and the telescopic bracing tubes form a variable triangular mechanism, and the triangular shape is controlled by controlling the length of the side in which the foot tubes are positioned, so that oblique desktops with different angles are obtained. The folding desk provided by the utility model has the advantages of simple structure and convenience in use, and is suitable for use in doors, camping, beaches, gardens and other occasions.

Description

A kind of folding desk

Technical field

The utility model relates to a kind of desk, particularly a kind of folding desk.

Background technology

A kind of common folding table of prior art, the utility model patent that name is called " folding table with expansion table top " was disclosed on January 21st, 2004 such as Chinese patent database, the patent No. is 02258660.1, a kind of folding table with expansion table top, it comprises desktop and table frame, it is characterized in that a frame is made of two fiddles, two folding stands and two extension table pin, and is corresponding with fiddle, desktop also has two, is installed in respectively on two fiddles; Be folding connection between two fiddles, an end of two folding stands links to each other with corresponding desktop respectively, and the other end joins with a corresponding table pin respectively.This employing support frame structure is realized the positioning supports between fiddle and the table pin, so that the table pin is stable bad, causes easily desktop to rock, simultaneously, the folding table of this structure, tabletop angles is single, can not carry out as required tilt adjustment.For above-mentioned shortcoming, be necessary to make improvement.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides the folding desk of a kind of tabletop angles tiltable adjusting and firm support desktop.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of folding desk mainly comprises desktop, positioning seat, pin pipe, down tube, end cover, flexible stay tube, hinged seat, extension, the pipe that lands, footmuff, hoodle, stull pipe, adapter; It is characterized in that four positioning seats are fixed under the desktop; A U-shaped pin pipe is placed in the positioning seat, and the port of pin pipe is provided with hoodle, and is placed in the extension; One end of extension is provided with hinged seat, the other end and adapter Joint; Be provided with the stull pipe between the adapter, the pipe that lands is hinged with adapter, and footmuff is installed in the corner of the pipe that lands; Down tube is placed in the positioning seat, and the termination of down tube is provided with the end cover; One end of flexible stay tube is provided with hoodle, and is placed in the down tube, and the other end and hinged seat are hinged.

Described down tube and pin pipe can rotate around positioning seat.

Described pin pipe, extension, stull pipe have formed the quadrilateral frame of rigidity, guarantee that extension and pin pipe are in same axle center.

Formed triangle mechanism between described desktop, pin pipe, down tube and the flexible stay tube.

The beneficial effects of the utility model are: desktop is provided with positioning seat, is provided with pin pipe and down tube in the positioning seat, and the pin pipe is provided with hoodle and is placed in the extension; Extension is installed on the adapter, and is provided with hinged seat; Down tube is provided with the end cover, and flexible stay tube one end is provided with hoodle, and is placed in the down tube, and the other end and hinged seat are hinged; Form variable triangle mechanism by desktop, pin pipe, down tube and flexible stay tube, by the length of side on limit, control pin pipe place, and then controlled leg-of-mutton shape, thereby obtained the inclination desktop of different angles; Therefore the utlity model has simple in structure, easy to operate and suitable indoor, camp, characteristics that the outdoor occasions such as sandy beach, garden are used.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of folding desk mainly comprises desktop 1, positioning seat 2, pin pipe 3, down tube 4, end cover 5, flexible stay tube 6, hinged seat 7, extension 8, pipe 9, footmuff 10, hoodle 11, stull pipe 12, adapter 13 land; It is characterized in that positioning seat 2 is fixed on desktop 1 time; Pin pipe 3 is placed in the positioning seat 2, and the port of pin pipe 3 is provided with hoodle 11, and is placed in the extension 8; One end of extension 8 is provided with hinged seat 7, the other end and adapter 13 Joints; Be provided with stull pipe 12 between the adapter 13, the pipe 9 that lands is hinged with adapter 13, and footmuff 10 is installed in the corner of the pipe 9 that lands; Down tube 4 is placed in the positioning seat 2, and the termination of down tube 4 is provided with end cover 5; One end of flexible stay tube 6 is provided with hoodle 11, and is placed in the down tube 4, and the other end and hinged seat 7 are hinged.

With reference to Fig. 2, during use, adapter 13 has limited the pipe 9 that lands and has clockwise rotated, thereby relative fixing with pipe 9 angles that land at force-bearing situation downward-extension pipe 8; Extension 9 is by hoodle 11 and pin pipe 3 Joints, and the gravity that bears of feet pipe 3; The gravity that the triangle mechanism supporting desktop 1 that is comprised of desktop 1, pin pipe 3, down tube 4 and flexible stay tube 6 bears, when regulating hoodle 11, variation that can the control pin pipe 3 place length of sides, thereby change leg-of-mutton shape, and then obtain the desktop 1 of differing tilt angles, at this moment, folding desk is in the use state after launching.

With reference to Fig. 3, when folding, desktop 1 landed set level first, then rotate the pipe 9 that the lands joint 13 that rotates and rotate counterclockwise, and it is naturally drooped.

With reference to Fig. 4, when continuing to fold, regulate hoodle 11, make pin pipe 3 convergent-divergents in extension 8, at this moment, in the triangle mechanism that is formed by desktop 1, pin pipe 3, down tube 4 and flexible stay tube 6, the pin pipe 3 place length of sides shorten, and by Triangle Principle as can be known, the angle between down tube 4 and the desktop 1 diminishes, be that down tube 5 rotates, and draw close to desktop 1.

With reference to Fig. 5, continue to regulate the hoodle 11 on the flexible stay tube 6 when folding, make the flexible stay tube 6 can be at down tube 4 interior free-extensions; Then rotate extension 8 and pin pipe 3 rotates counterclockwise around positioning seat 2, and make flexible stay tube 6 convergent-divergents in down tube 4, down tube 4 and the flexible stay tube 6 place length of sides are shortened, until down tube 4 and flexible stay tube 6 fit with desktop 1, the pipe 9 that lands fits with down tube 4, and at this moment, folding table is folded into flat, smaller volume is convenient for carrying and transports.

Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
