Abstract

Provided is a folding desk. Vertical foot tubes are perpendicularly and fixedly connected to cross foot tubes, the other end of each vertical foot tube is fixedly connected with a middle connector, each middle connector is provided with two desk frame tubes which are symmetrical left and right, every two desk frame tubes are fixedly connected through a desk frame connecting piece, and a desk face plate is fixedly connected to the desk frame connecting pieces through screws. Sliding blocks are provided with locating bolts and are connected to the vertical foot tubes in a sleeved mode, oblique supporting tubes are hinged to the sliding blocks and the desk frame tubes respectively, each sliding block and the corresponding vertical foot tube are connected through a tongue-and-groove structure, bolts are used for adjusting the clearance of each tongue-and-groove structure, and therefore variable triangular mechanisms formed by the desk frame tubes, the oblique supporting tubes and the vertical foot tubes are controlled, the angle state of the desk face plate is adjusted, and the desk can be folded or unfolded. The folding desk has the advantages that the structure is simple, operation is convenient, and the desk is suitable for being used indoors, in yards 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

The conventional desk of family adopts the dismountable structure of table leg at present, yet most crowd is less with room area, the space that desk occupies is larger, and when desk is not often used, the space that reduces desk by dismounting mode is more loaded down with trivial details and expend time in actual use.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 provide the folding desk of a kind of convenience solve joint feed consumption many, use the problems such as loaded down with trivial details.

The utility model solves the technical scheme that its technical problem adopts: a kind of folding desk, and it comprises desktop, table frame brace, screw, end cover, down tube, transition joint, table frame pipe, perpendicular pin pipe, horizontal pin pipe, foot pad, slide block and bolt; It is characterized in that on two horizontal pin pipes that be arranged in parallel vertical affixed two perpendicular pin pipes that be arranged in parallel respectively; Affixed two transition joints of the other end of perpendicular pin pipe, each transition joint is provided with two table frame pipes that are symmetrical set; Between two groups of table frame pipes, by four table frame braces, be fixed together; Two desktops are fixed on a frame brace by screw; Slide block is provided with bolt, and is socketed on perpendicular pin pipe; The two ends of four down tubes are provided with end cover, and are hinged with slide block and table frame pipe respectively; Foot pad is installed on horizontal pin pipe.

Described perpendicular pin pipe is provided with groove face, and described slide block is provided with the tenon face with groove face similar shape, and slide block is installed in the groove face on perpendicular pin pipe by tenon face.

Described bolt is provided with external screw thread, by bolt, regulates tenon groove structure gap.

Described slide block can slippage on perpendicular pin pipe, by bolt, regulate tenon groove structure gap, realize relative fixing between slide block and perpendicular pin pipe, make a frame pipe, down tube, perpendicular pin pipe form variable triangle mechanism by transition joint, slide block, the support angle of desktop is realized and being regulated and positioning supports.

The beneficial effects of the utility model are: between slide block and perpendicular pin pipe, adopt tenon groove structure to be connected, and by bolt, regulate the gap of tenon groove structure, thereby control by the variable triangle mechanism forming between table frame pipe, down tube and perpendicular pin pipe, and then the angle state of adjustment desktop, finally realize expansion or the folding of desk, therefore the utlity model has simple in structure, easy to operately, be applicable to the features such as various occasion uses such as indoor, garden.

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, it comprises desktop 1, table frame brace 2, screw 3, end cover 4, down tube 5, transition joint 6, table frame pipe 7, perpendicular pin pipe 8, horizontal pin pipe 9, foot pad 10, slide block 11 and bolt 12; It is characterized in that vertical affixed perpendicular pin pipe 8 on horizontal pin pipe 9, the affixed transition joint 6 of the other end of perpendicular pin pipe 8, the hinged table frame pipe 7 being symmetrical set in transition joint 6; Between table frame pipe 7, by table frame brace 2, be fixed together; Desktop 1 is fixed on a frame brace 2 by screw 3; Slide block 11 is provided with bolt 12, and is socketed on perpendicular pin pipe 8; The two ends of down tube 5 are provided with end cover 4, and are hinged with slide block 11 and table frame pipe 8 respectively; Foot pad 10 is installed on horizontal pin pipe 9.

With reference to Fig. 2, perpendicular pin pipe 8 is provided with groove face 81, slide block 11 is provided with the tenon face 111 with groove face 81 similar shapes, slide block 11 is installed in the groove face 81 on perpendicular pin pipe 8 by tenon face 111, and tenon face 111 can be in the interior slippage of groove face 81, by screwing bolt 12, until external screw thread 121 is inconsistent with groove face 81, causing the splaying between tenon face 111 and groove face 81 to increase, there is extruding in the other end, and the frictional force producing by extruding force realizes the relative positioning between tenon face 111 and groove face 81.

With reference to Fig. 3, during use, by slide block 11 upwards slippages, and then promotion is by triangular shaped the changing forming between perpendicular pin pipe 8, down tube 5 and table frame pipe 7, until table frame pipe 7 and desktop 1 are in level, now, by screwing bolt 12, make to realize and being located by connecting between slide block 11 and perpendicular pin pipe 8, now, the use state of folding desk after launching.

With reference to Fig. 4, when folding, by unscrewing between bolt 12 releasing slide blocks 11 and perpendicular pin pipe 8, be located by connecting, and by slide block 11 along the downward slippage of perpendicular pin pipe 8, by triangular shaped the changing forming between perpendicular pin pipe 8, down tube 5 and table frame pipe 7, now, folding desk is in folded state.

With reference to Fig. 5, while continuing to fold, continuation by slide block 11 along the downward slippage of perpendicular pin pipe 8, by triangular shaped continuation theing form between perpendicular pin pipe 8, down tube 5 and table frame pipe 7, changed, until table frame pipe 7 and desktop 1 are in vertical state, now, taking up room of folding desk diminishes, and saves indoor depositing and usage space.
